Cleaning device

Abstract

This invention relates to a ridging device assembly, comprising a mounting assembly, first and second ridging device arms, a guide wheel, a linkage device, and an actuator. The mounting assembly is connected to the tool bar of an agricultural planter. The first and second ridging device arms respectively support first and second ridging device wheels, each rotatable about a corresponding first and second ridging device wheel axle. The guide wheel is disposed between the first and second ridging device arms and rotatably supported on a guide wheel axle located behind the first and second ridging device wheel axles. The linkage device operably supports the first and second ridging device arms and the guide wheel axle from the mounting assembly. The actuator is connected to the linkage device such that when the actuator is actuated, the downward pressure applied to the soil surface by the guide wheel changes.

Background Technology

[0003] The ridging device is positioned in front of the furrowing assembly on the planter to move any crop residue, clods of soil, or other debris laterally outward, thereby preparing a ridging bed area for the rear-aligned furrowing assembly, which opens seed furrows in which seeds are deposited. While many commercially available ridging devices fulfill their intended purpose, there is still a need for a ridging device assembly that provides improved performance. Attached Figure Description

[0109] The entire contents of all references cited in this paper are incorporated herein by reference. In the event of any conflict between the definitions in this paper and those in the incorporated references, the definitions in this paper shall prevail.

[0110] Referring now to the accompanying drawings, where similar reference numerals are used throughout several drawings to designate the same or corresponding parts. Figure 1 The diagram shows a tractor 5 towing an agricultural planter 10 in the forward direction indicated by arrow 11. The planter 10 includes a tool bar 14 that operatively supports multiple planter ridge units 200. A planter monitor 50 may be located in the cab of the tractor 5, and the planter monitor 50 may include a central processing unit (“CPU”), memory, and a graphical user interface (“GUI”) (e.g., a touchscreen interface). A global positioning system (“GPS”) receiver 52 may be mounted to the tractor 5.

[0111] Figure 2This is a side view of an embodiment of a planting machine ridge unit 200. The ridge unit 200 includes a ridge unit frame 210, which includes a downwardly extending handle 254 and a rearwardly extending frame member 212 supported from a forward support 214. The ridge unit frame 210 may also include an upper beam 215, also supported by the forward support 214. The upper beam 215 may support one or more hoppers 226 that contain a supply of seeds and optionally a supply of fertilizer or other chemical inputs. The ridge unit frame 202 may be pivotally connected to a tool bar 14 by parallel links 216. An actuator 218 may be configured to apply an upward force and / or downward pressure to the ridge unit 200. A solenoid valve 390 may be fluidly communicated with the actuator 218 for modifying the upward force and / or downward pressure applied by the actuator 218. The opening system 234 may include two opening discs 244, which are slidably mounted to a downwardly extending handle 254 and configured to open V-shaped trenches 38 in the soil 40. A pair of guide wheels 248 may be pivotally supported from the frame member 204 by a pair of corresponding guide wheel arms 260. It is known that the upward travel of the guide wheels 248 relative to the opening discs 244 defines the depth of the trench 38. A depth adjustment rocker arm 268 limits the upward travel of the guide wheel arms 260, and thus limits the upward travel of the guide wheels 248. A depth adjustment actuator 380 may be configured to modify the position of the depth adjustment rocker arm 268, and thus modify the height of the guide wheels 248. The actuator 380 may be a linear actuator mounted to the ridge unit 200 and pivotally coupled to the upper end of the rocker arm 268. In some embodiments, the depth adjustment actuator 380 may include the means disclosed in International Patent Application No. PCT / US2012 / 035585 (Publication No. WO2012149415). The encoder 382 may be configured to generate a signal relating to the linear extension of the actuator 380; it should be understood that the linear extension of the actuator 380 is relating to the depth of the trench 38 when the guide wheel arm 260 contacts the rocker arm 268. The downpressure sensor 392 may be configured to generate a signal relating to the amount of force applied to the soil 40 by the guide wheel 248; in some embodiments, the downpressure sensor 392 may include instrumentation pins about which the rocker arm 268 is pivotally coupled to the ridge unit 200, such as those disclosed in U.S. Patent Publication No. US2010 / 0180695.

[0112] Continue to refer to Figure 2Seed meter 230 (e.g., the seed meter disclosed in International Patent Application No. PCT / US2012 / 030192 (Publication No. WO2012129442)) can be configured to deposit seeds 42, for example, from hopper 226 into trench 38 through seed tube 232, which is configured to guide the seeds toward the trench. In some embodiments, seed meter 230 can be powered by an electric actuator 315 configured to drive a seed disk within the seed meter. In other embodiments, actuator 315 may include a hydraulic actuator configured to drive the seed disk. Seed sensor 305 (e.g., an optical or electromagnetic seed sensor configured to generate a signal indicating the passage of a seed) can be mounted to seed tube 232 and configured to transmit light or electromagnetic waves across the path of seed 42 to detect the passage of each seed. Closing system 236, which may include one or more closing wheels, can be pivotally coupled to ridge unit 200 and configured to close trench 38.

[0113] Figure 2 An embodiment of a ridge clearer assembly 1000 is also shown, which is mounted to the tool bar 14 and positioned in front of the furrowing assembly 234. It should be understood that each ridge unit 200 of the planter 10 will have an associated ridge clearer assembly 1000, which is longitudinally aligned with the corresponding furrowing assembly 234 of the ridge unit 200. In the illustrated embodiment, the ridge clearer assembly 1000 includes guide wheels 1050 (e.g., ...). Figure 3 (As shown). The clearer assembly 1000 extends toward the rear of the tool bar 14 and is rigidly mounted to the underside of the tool bar 14 by a suitable mounting structure, which may include a mounting plate 1101 and one or more U-bolts 1001, as shown. Alternatively, the clearer assembly 1000 can be mounted to the top, rear, or front side of the tool bar 14 by any suitable mounting structure or connector (including bolt brackets or by welding).

[0114] Figure 2A Alternative embodiments of the clearer assembly designated by reference numeral 1000A are shown. The embodiment of clearer assembly 1000A is substantially the same as the embodiment of clearer assembly 1000, except that the embodiment of 1000A does not include guide wheels.

[0115] Figure 3 yes Figure 2 An enlarged rear perspective view of the cleaning unit 1000 shown. Figure 3A The view and Figure 3The views are the same, but an embodiment of the clearer assembly 1000A without the guide wheel is shown. Since the two embodiments of clearer assemblies 1000 and 1000A are substantially the same, only embodiment 1000 is described except for the removal of the guide wheel in embodiment 1000A. It should be understood that any references to the guide wheel 1050, guide wheel shaft 1051, and associated components will not apply to embodiment 1000A.

[0116] Figure 4 and Figure 5 These are the right and left views of the cleaning unit 1000. Figure 6 and Figure 7 These are the front view and the rear view, respectively. Figure 8 and Figure 9 These are top and bottom views, respectively. The ridging assembly 1000 includes a frame assembly 1100 supported at its rear end by guide wheels 1050. Riddler wheels 1060-1 and 1060-2 are rotatably supported by the frame assembly 1100. Each ridging wheel 1060-1 and 1060-2 includes radially spaced teeth 1062 around its circumference. The ridging wheels 1060-1 and 1060-2 are oriented outward and rearward, such that the teeth 1062 of the ridging wheels 1060-1 and 1060-2 are interlaced at their front ends as they rotate. In operation, as the planter 10 moves in the forward direction 11, the soil engages with the teeth 1062, causing the ridging wheels 1060-1 and 1060-2 to rotate. Due to their orientation, as the ridging wheels 1060-1 and 1060-2 rotate, they guide any crop residue, clods of soil, or other debris laterally outward to provide a ridging bed for the rearward-aligned furrowing assembly 234. Before the furrow 38 is opened by the furrowing assembly 234, the guide wheel 1050 is used to compact the soil 40 that will be disturbed by the ridging wheels 1060-1 and 1060-2. Compacting the soil with the guide wheel 1050 in dry soil helps prevent soil 40 from falling into the furrow 38.

[0117] An actuator system 1300 is positioned within the frame assembly 1100 to provide adjustable downforce and optional upforce to the guide wheel 1050 and the clearer wheels 1060-1, 1060-2. In this embodiment, the actuator system 1300 includes a pneumatic cylinder 1302; however, the actuator system 1300 can utilize any actuator that provides adjustable downforce and optional upforce, including pneumatic cylinders, hydraulic cylinders, airbags, and electromechanical actuators, as will be discussed in more detail later.

[0118] Figure 10 This is a rear perspective view of frame assembly 1100, with guide wheels 1050, clearer wheels 1060-1, 1060-2 and actuator system 1300 removed for clarity. Figure 11This is a front perspective view of the frame assembly 1100 with the guide wheel 1050, actuator system 1300, and first clearer wheel 1060-1 removed, but an exploded view of the second clearer wheel 1060-2 and its mounting components is shown. Figure 12 This is a rear perspective view of the exploded frame component 1100. See reference 10 to... Figure 12 The frame assembly 1100 includes an upper subframe 1100A, a middle subframe 1100B, a lower subframe 1100C, a rear support subframe 1100D, and a first side link 1200-1 and a second side link 1200-2. The rear support subframe 1100D includes a portion of the lower subframe 1100C. The components including subframes 1100A, 1100B, 1100C, and 1100D will be described in more detail later.

[0119] like Figure 12As best shown, the intermediate subframe 1100B is pivotally connected at its front end to the upper subframe 1100A via threaded connectors 1002 received in alignment apertures 1003 and 1004 in the respective intermediate subframe 1100B and the upper subframe 1100A. The intermediate subframe 1100B is also pivotally connected at its rear end to the rear pillar subframe 1100D via threaded connectors 1006 received in alignment apertures 1007 and 1008 in the respective intermediate subframe 1100B and the rear pillar subframe 1100D, which includes a portion of the lower subframe 1100C. The first side link 1200-1 and the second side link 1200-2 are pivotally connected at their front ends to the upper subframe 1100A via threaded connectors 1010 received in alignment holes 1011 and 1012 in the respective first side link 1200-1 and the second side link 1200-2. The first side link 1200-1 and the second side link 1200-2 are pivotally connected at their rear ends to the rear support subframe 1100D via threaded connectors 1014 received in alignment holes 1015 and 1016 in the respective first side link 1200-1 and the second side link 1200-2. The rear support subframe 1100D is rotatably fixed to the lower subframe 1100C via a threaded connector 1018, which is received within an arcuate slot 1019 in the lower frame 1100C and threadably engages with an opening 1021 in the rear support subframe 1100D. The rear support subframe 1100D is connected to the lower frame 1100C via guide wheel shaft bolts 1051, which are received through alignment holes 1022, 1023 in the respective lower frame 1100C and rear support subframe 1100D. It should be apparent that in embodiment 1000A, where the guide wheel 1050 is omitted, a short bolt extending through holes 1022, 1023 and secured by a nut (not shown) can replace the guide wheel shaft bolt 1051. It should be understood that the forward pivoting connection between the upper subframe 1100A and the middle subframe 1100B and the side links 1200-1, 1200-2, together with the rearward pivoting connection between the middle subframe 1100B and the side links 1200-1, 1200-2 and the rear support subframe 1100D, provides a four-bar linkage mechanism that allows the middle subframe 1100B and the lower subframe 1100C to move vertically relative to the upper subframe 1100A, which is rigidly fixed to the tool bar 14.

[0120] Figure 13An exploded front perspective view of the upper subframe 1100A is shown. The upper subframe 1100A includes a first gusset plate 1102-1 and a second gusset plate 1102-2 extending downward from the mounting plate 1101 and laterally spaced by the front plate 1104. The gusset plates 1102-1 and 1102-2 may include gusset tabs 1105 received in gusset tab slots 1106 in the mounting plate 1101. The front plate 1104 includes a cutout 1107 to receive an actuator 1302 passing through it (see [link to documentation]). Figures 6 to 7 The front panel 1104 may include actuator front mounting lugs 1108-1, 1108-2 extending downward from the front panel 1104. Each of the actuator front mounting lugs 1108-1, 1108-2 may include a hole 1109 to receive a pin 1110. Figure 11 ), for mounting the front end of actuator 1302 to upper subframe 1100A (see Figure 6 Each of the actuator front mounting lugs 1108-1 and 1108-2 may include a lug tab 1111, which is received within a corresponding lug tab slot 1112 in the front plate 1104. The front plate 1104 may also include side tabs 1113, which are received within side tab slots 1114 in the gusset plates 1102-1 and 1102-2. It should be understood that the various parts of the upper subframe 1100A are not connected using tabs and slots, but rather by welding or by bolted connections. Alternatively, the upper subframe 1100A may be manufactured as a single part, for example, by casting. The gusset plates 1102-1 and 1102-2 include apertures 1004 for receiving threaded connectors 1002, for pivotally securing the intermediate subframe 1100B to the gusset plates 1102-1 and 1102-2, as described above. Figure 12 As described above. Furthermore, the gusset plates 1102-1 and 1102-2 include apertures 1012 for receiving threaded connectors 1010, for pivotally securing the first side link 1200-1 and the second side link 1200-2 to the gusset plates 1102-1 and 1102-2, as referred to above. Figure 12 As described. The gusset plates 1102-1 and 1102-2 also include apertures 1115 and 1116 for receiving the upper threaded connector 1117 and the lower threaded connector 1118. Figure 11 and Figure 12 The upper threaded connector 1117 and the lower threaded connector 1118 act as upper and lower stops by abutting the first side link 1200-1 and the second side link 1200-2 to restrict the upward and downward vertical movement of the four-bar linkage.

[0121] Figure 14An exploded rear perspective view of the intermediate subframe 1100B is shown. The intermediate subframe 1100B includes a base member 1120 and a first side guide rail 1121-1 and a second side guide rail 1121-2. The base member 1120 includes a cutout 1122 to accommodate an actuator 1302 (see [link to documentation]). Figure 3 and Figure 6 The base member 1120 may include a side tab 1123, which is received within a side tab slot 1124 in the side guides 1121-1, 1121-2. The rear end of the base member 1120 may include an actuator rear mounting lug 1125. The actuator rear mounting lug 1125 may include a hole 1126 to receive a pin 1127. Figure 3 and Figure 10 The actuator rear mounting lug 1125 may include a lug tab 1128 received within a lug tab slot 1129 in the base member 1120. It should be understood that the individual parts of the intermediate subframe 1100B are not connected using tabs and slots, but rather by welding or bolted connections. Alternatively, the intermediate subframe 1100B may be manufactured as a single part, for example, by casting. Side rails 1121-1, 1121-2 include forward openings 1003 for receiving threaded connectors 1002, for pivotally securing the side rails 1121-1, 1121-2 of the intermediate subframe 1100B to the corner plates 1102-1, 1102-2 of the upper subframe 1100A, as referenced above. Figure 12 As described above, the side guide rails 1121-1 and 1121-2 include rearward openings 1007 for receiving threaded connectors 1006, for pivotally securing the side guide rails 1121-1 and 1121-2 of the intermediate subframe 1100B to the rear support subframe 1100D, as referenced above. Figure 12 As described.

[0122] Figure 15An exploded rear perspective view of the lower subframe 1100C is shown. The lower subframe 1100C includes a first auger wheel support arm 1130-1 and a second auger wheel support arm 1130-2, which are connected at their front ends by a front plate 1132. The front plate 1132 may include side tabs 1133 received within side tab slots 1134 in the first auger wheel support arm 1130-1 and the second auger wheel support arm 1130-2. It should be understood that the individual parts of the lower subframe 1100C are not connected using tabs and slots, but rather by welding or by bolted connections. Alternatively, the lower subframe 1100C may be manufactured as a single part, for example, by casting. Each of the first clearer wheel support arm 1130-1 and the second clearer wheel support arm 1130-2 includes a square opening 1135 for receiving clearer wheel axle bolts 1061-1, 1061-2. Figure 11 The corresponding square handle portion 1063 in ) Figure 11 (This will be discussed in more detail later.) Each cleaning wheel support arm 1130-1, 1130-2 also includes an opening 1022 for receiving the guide wheel shaft bolt 1051, as shown below. Figures 10 to 12 As shown. Each clearer wheel support arm 1130-1, 1130-2 also includes an arcuate slot 1019 for receiving a threaded connector 1018, which is threadably received by the rear support subframe 1100D, for securing the clearer wheel support arms 1130-1, 1130-2 to the rear support subframe 1100D, as referenced above. Figure 12 As described. It should be understood that the arcuate slot 1019 and the threaded connector 1018 cooperate to form a depth selector 1400, thereby allowing the lower subframe 1100C to pivot about the guide wheel shaft bolt 1051, such that the cleaning wheels 1060-1, 1060-2 are adjustablely positioned relative to the rear support subframe 1100D and the guide wheel 1050 to change the depth setting of the cleaning wheels 1060-1, 1060-2 relative to the guide wheel 1050. Figure 16 In the alternative embodiment shown, a series of discrete openings 1019a arranged along an arc can be used instead of a single arcuate slot 1019 to provide discrete depth settings for the cleaning wheels 1060-1, 1060-2 relative to the guide wheel 1050.

[0123] Figure 17This is a rear perspective view of the rear strut subframe 1100D. The rear strut subframe 1100D includes a first strut 1140-1 and a second strut 1140-2 spaced apart by side plates 1142. The side plates 1142 may include tabs 1143 received within slots 1144 in each of the first strut 1140-1 and the second strut 1140-2. Alternatively, the side plates 1142 may be attached to the struts 1140-1 and 1140-2 by welding or bolting. Alternatively, the struts 1140-1 and 1140-2 and the side plates 1142 may be manufactured as a single part, for example, by casting. Each of the first support 1140-1 and the second support 1140-2 includes an aperture 1016 for receiving a threaded connector 1014 for connection with a corresponding side link 1200-1, 1200-2, and each of the first support 1140-1 and the second support 1140-2 includes an aperture 1023 for receiving a guide wheel shaft bolt 1051, as referenced above. Figure 12 As described.

[0124] The rear strut subframe 1000D may include a scraper 1145 to remove dirt or debris that may accumulate on the guide roller 1050 during operation. The scraper 1145 may be attached to a side plate 1142 between the rear struts 1140-1 and 1140-2 of the rear strut subframe 1000D, and may include a plate with a curved edge 1146 that approximates the contour of the guide roller 1050 (see [link to relevant documentation]). Figure 3 , Figure 7 and Figure 8 The scraper 1145 can be attached to the side plate 1142 by means of a threaded connector 1148 extending through an elongated hole 1147 that aligns with an internally threaded aperture 1149 in the side plate 1142. The elongated hole 1147 allows the scraper 1145 to be adjusted relative to the side plate 1142 to change the distance from the guide wheel 1050 to accommodate different guide wheel sizes and profiles, as well as to take into account wear on the guide wheel surface and the scraper 1145.

[0125] Reference Figure 11The square opening 1135 in each of the cleaner wheel support arms 1130-1, 1130-2 and the square shank portion 1063 of the cleaner wheel axle bolts 1061-1, 1061-2 cooperate to rotatably constrain the cleaner wheel axle bolts 1061-1, 1061-2 to the cleaner wheel support arms 1130-1, 1130-2. Each cleaner wheel axle bolt 1061-1, 1061-2 receives a spacer 1063. Each cleaner wheel axle bolt 1061-1, 1061-2 extends through a central opening 1064 within each of the corresponding first cleaner wheel 1060-1 and second cleaner wheel 1060-2. A bushing 1065 is received at the end of each cleaner wheel axle bolt 1061-1, 1061-2, and the bushing is received within a hub 1070 having a central opening 1071. Hub 1070 is secured to the respective first clearer wheel 1060-1 and second clearer wheel 1060-2 by nuts 1072, which are threadably received on threaded connector 1074, extending through orifices 1066 in clearer wheels 1060-1 and 1060-2 and through alignment holes 1073 in hub 1070. Lug nuts 1075 threadably receive the ends of axle bolts 1061-1 and 1061-2, thereby axially constraining clearer wheels 1060-1 and 1060-2 to the respective clearer wheel axle bolts 1061-1 and 1061-2, while spacers 1063 and bushings 1065 allow clearer wheels 1060-1 and 1060-2 to rotate freely about the respective clearer wheel axle bolts 1061-1 and 1061-2.

[0126] Return to reference Figure 3 and Figure 12 The guide wheel shaft bolt 1051 passes through the alignment holes 1022, 1023 in the corresponding first clearer wheel support arm 1130-1 and second clearer wheel support arm 1130-2 of the lower subframe 1100C with the supports 1140-1, 1140-2 of the rear support subframe 1100D and through the hub 1052 of the guide wheel 1050. Figure 3 ) extension. Spacer bushing 1053 ( Figure 12 A guide wheel 1050 can be mounted on a guide wheel shaft bolt 1051 on each side of the hub 1052 to keep the guide wheel 1050 centered between the supports 1140-1 and 1140-2. A nut 1054 is threaded onto the end of the guide wheel shaft bolt 1051, thereby securing the guide wheel 1050 to the lower subframe 1100C and the rear support subframe 1100D.

[0127] As previously described, actuator system 1300 can utilize any actuator that provides adjustable downforce and optional upforce, including pneumatic cylinders, hydraulic cylinders, airbags, and electromechanical actuators. In one embodiment, actuator 1302 including actuator system 1300 is a CleenSweep® cylinder available from Precision Planting LLC, 23207 Townline Rd, Tremont, IL 61568, as described in U.S. Patent No. 8,550,020, or a DeltaForce® cylinder also available from Precision Planting, as described in U.S. Patent No. 9,144,189. The downforce applied to guide wheel 1050 by actuator system 1302 can be controlled by a controller (e.g., “Controller 300” referenced in U.S. Patent No. 8,550,020) or by a fluid control port (e.g., “Fluid Control Port 10” described in PCT Publication No. WO2020 / 056395). The actuators 1302 of each clearer assembly 1000 of the planter 10 can be controlled row by row, or controlled by a portion of the planter 10 as a group, or collectively controlled on the entire planter 10.

[0128] The desired amount of downforce can be a function of soil conditions and the amount or type of crop residue, as well as the depth to which the ridging wheel 1060 engages with the soil. For example, under dry soil conditions, greater downforce can be expected, causing the guide wheel 1050 to more firmly pack the soil 40 in front of the opening assembly 234 for better seed furrow 38 formation and to prevent or minimize soil falling into the seed furrow 38 before seeds are deposited. Alternatively, under wet soil conditions, less downforce can be expected. A downforce monitoring system (discussed later) can be used to determine and adjust the downforce applied by the actuator system 1300.

[0129] Figure 18 This is a side view of the planting machine ridge unit 200, as previously referred to above. Figure 2 The described embodiment, however, includes a different ridging assembly designated by reference numeral 2000. The ridging assembly 2000 is mounted on the tool bar 14 and positioned in front of the furrowing assembly 234. Again, it should be understood that each ridge unit 200 of the planter 10 will have an associated ridging assembly 2000, which is longitudinally aligned with the corresponding furrowing assembly 234 of the ridge unit 200. In the illustrated embodiment, the ridging assembly 2000 includes guide wheels 2050 (such as...). Figure 19(As shown). The clearer assembly 2000 extends toward the rear of the tool bar 14 and is rigidly mounted to the underside of the tool bar 14 by a suitable mounting structure, which may include a mounting plate 2101 and one or more U-bolts 2001, as shown. Alternatively, the clearer assembly 2000 can be mounted to the top, rear, or front side of the tool bar 14 by any suitable mounting structure or connector (including bolt brackets or by welding).

[0130] Figure 18A Alternative embodiments of the clearer assembly designated by reference numeral 2000A are shown. The embodiment of clearer assembly 2000A is substantially the same as the embodiment of clearer assembly 2000, except that the embodiment of 2000A does not include guide wheels.

[0131] Figure 19 yes Figure 18 An enlarged rear perspective view of the cleaning unit 2000 shown. Figure 19A The view and Figure 19 The views are the same, but an embodiment of the clearer assembly 2000A without the guide wheel is shown. Since the two embodiments of clearer assemblies 2000 and 2000A are substantially the same, only embodiment 2000 is described except for the removal of the guide wheel in embodiment 2000A. It should be understood that any references to the guide wheel 2050, guide wheel shaft 2051, and associated components do not apply to embodiment 2000A.

[0132] Figure 20 and Figure 21 These are the right and left views of the cleaning unit 2000. Figure 22 and Figure 23 These are the front view and the rear view, respectively. Figure 24 and Figure 25These are top and bottom views, respectively. The ridging assembly 2000 includes a frame assembly 2100 supported at its rear end by guide wheels 2050. Riddler wheels 2060-1 and 2060-2 are rotatably supported by the frame assembly 2100. Each ridging wheel 2060-1 and 2060-2 includes radially spaced teeth 2062 around its circumference. The ridging wheels 2060-1 and 2060-2 are oriented outward and rearward, such that the teeth 2062 of the ridging wheels 2060-1 and 2060-2 are interlaced at their front ends as they rotate. In operation, as the planter 10 moves in the forward direction 11, the soil engages with the teeth 2062, causing the ridging wheels 2060-1 and 2060-2 to rotate. Due to their orientation, as the ridging wheels 2060-1 and 2060-2 rotate, they guide any crop residue, clods of soil, or other debris laterally outward to provide a ridging bed for the rearward-aligned furrowing assembly 234. Before the furrow 38 is opened by the furrowing assembly 234, the guide wheel 2050 is used to compact the soil 40 that will be disturbed by the ridging wheels 2060-1 and 2060-2. Compacting the soil with the guide wheel 2050 in dry soil helps prevent soil 40 from falling into the furrow 38.

[0133] An actuator system 2300 is positioned within the frame assembly 2100 to provide adjustable downforce and optional upforce to the guide wheel 2050 and the clearer wheels 2060-1, 2060-2. In this embodiment, the actuator system 2300 includes an air bladder 2302 and a spring assembly 2310; however, the actuator system 2300 can utilize any actuator that provides adjustable downforce and optional upforce, including pneumatic cylinders, hydraulic cylinders, air bladders, and electromechanical actuators, as will be discussed in more detail later.

[0134] Figure 26 This is a rear perspective view of frame assembly 2100. For clarity, guide wheels 2050, cleaning wheels 2060-1, 2060-2, and actuator system 2300 have been removed. Figure 27 This is a front perspective view of the frame assembly 2100 with the guide wheel 2050, actuator system 2300, and first clearer wheel 2060-1 removed, but an exploded view of the second clearer wheel 2060-2 and its mounting components is shown. Figure 28 This is the rear perspective view of the exploded frame component 2100. (See reference...) Figures 26 to 28 The frame assembly 2100 includes an upper subframe 2100A, a middle subframe 2100B, a lower subframe 2100C, a rear support subframe 2100D, and a first link 2200-1 and a second link 2200-2. The rear support subframe 2100D includes a portion of the lower subframe 2100C. Subframes 2100A, 2100B, 2100C, and 2100D will be described in more detail later.

[0135] like Figure 28 As best shown, the intermediate subframe 2100B is pivotally connected at its front end to the upper subframe 2100A via a threaded connector 2002 received in alignment apertures 2003, 2004 in the respective intermediate subframe 2100B and the upper subframe 2100A. The intermediate subframe 2100B is pivotally connected at its rear end via a threaded connector 2006 received in alignment apertures 2007, 2008, and 2009 in the respective intermediate subframe 2100B, the rear support subframe 2100D, and the lower subframe 2100C. It should be understood that aperture 2007 in the rear end of the intermediate subframe 2100B is internally threaded for receiving the threads of the threaded connector 2006. The aperture 2008 in the rear support subframe 2100D is sized to pivotally receive the unthreaded shank of the threaded connector 2006, and the aperture 2008 in the lower subframe 2100C is an elongated opening 2008, sized to receive the head of the threaded connector 2006. Therefore, the lower subframe 2100C is not connected to the rear support subframe via the threaded connector 2006. Instead, the elongated opening 2008 serves as a guide within which the head of the threaded connector 2006 moves.

[0136] The first link 2200-1 and the second link 2200-2 are pivotally connected at their front ends to the upper subframe 2100A via threaded connectors 2010 received in alignment holes 2011 and 2012 in the respective first link 2200-1 and the second link 2200-2. The first link 2200-1 and the second link 2200-2 are pivotally connected at their rear ends to the rear support subframe 2100D via threaded connectors 2014 received in alignment holes 2015 and 2016 in the respective first link 2200-1 and the second link 2200-2.

[0137] The rear support subframe 2100D is rotatably secured to the lower subframe 2100C via a threaded connector 2018, which is received within an arcuate slot 2019 in the lower frame 2100C and threadably engages with a threaded orifice 2021 in the rear support subframe 2100D. The rear support subframe 2100D is connected to the lower subframe 2100C via guide wheel shaft bolts 2051, which are received via alignment holes 2022, 2023 in the respective lower frame 2100C and the rear support subframe 2100D. It should be apparent that in the 2000A embodiment, where the guide wheel 2050 is omitted, a short bolt can extend through holes 2022, 2023 and be secured by a nut (not shown) instead of the guide wheel shaft bolt 2051. It should be understood that the forward pivoting connection between the upper subframe 2100A and the middle subframe 2100B and the links 2200-1, 2200-2, together with the rearward pivoting connection between the middle subframe 2100B and the links 2200-1, 2200-2 and the rear support subframe 2100D and the lower subframe 2100C, provides a four-bar linkage mechanism that allows the middle subframe 2100B and the lower subframe 2100C to move vertically relative to the upper subframe 2100A, which is rigidly fixed to the tool bar 14.

[0138] Continue to refer to Figure 28 The exploded view shows that the rear support subframe 2100D may also include an optional depth selector 2400 to change the depth setting of the cleaning wheels 2060-1, 2060-2 relative to the guide wheel 2050. The depth selector 2400 includes a finger screw 2024 having a threaded shank and a pin end. The threaded shank of the finger screw 2024 is threaded into an internally threaded hole 2025 in the lower subframe 2100C, while the pin end of the finger screw 2024 engages with one of a series of discrete holes 2026 arranged in an arcuate pattern in the rear support subframe 2100D. It should be understood that the relative angle or position of the lower subframe 2100C can be movably adjusted relative to the rear support subframe 2100D by loosening the threaded connector 2018, which passes through an arcuate slot 2019 into a threaded orifice 2021. When the lower subframe 2100C is adjusted to the desired angle or position (the threaded connector moves within the arcuate slot 2019, and the threaded connector 2006 moves within the elongated opening 2009), the finger screw 2024 can be rotated to cause the pin end to seat within one of the discrete holes 2026. The threaded connector 2018 can then be tightened to secure the lower subframe 2100C to the rear support subframe 2100D. Alternatively, as described above... Figure 16As described in embodiment 1000 of the clearer, the arcuate slot 2019 can be replaced by a series of discrete holes arranged in an arc (not shown, but similar to...). Figure 16 (corresponding to hole 2019a in the middle), and the finger screw 2024 and holes 2019 and 2026 will be eliminated, but the use of the aforementioned depth selector 2400 makes it easier to set the desired angle or position of the lower subframe 2100c relative to the rear support subframe 2100d.

[0139] Continue to refer to Figure 28 A spring assembly 2310, which is part of an actuator system 2300 (discussed later), is secured to an intermediate subframe 2100B via a threaded connector 2028, which is received in alignment holes 2029 and 2030 in the lower rod 2302 of the corresponding intermediate subframe 2100B and the spring assembly 2310. The spring assembly 2310 is secured to an upper subframe 2100A via a threaded connector 2032, which is received in alignment holes 2033 and 2034 in the corresponding upper subframe 2100A and the U-shaped bracket 2320 (discussed later) of the spring assembly 2310.

[0140] Continue to refer to Figure 28 The threaded connector 2036 passes through the arcuate opening 2037 in the upper subframe 2100A and is received within the orifice 2038 in the intermediate subframe 2100B. As discussed later, as the intermediate subframe 2100D moves relative to the upper subframe 2100B (as part of a four-bar linkage), the threaded connector 2036 moves along the arcuate opening 2037. When the threaded connector 2026 abuts against the upper end of the arcuate opening 2037, it acts as an upper stop, preventing the intermediate subframe 2100B from moving further upward. When the threaded connector 2026 abuts against the lower end of the arcuate opening 2037, it acts as a lower stop, preventing the intermediate subframe 2100B from moving further downward.

[0141] Figure 29An exploded front perspective view of the upper subframe 2100A is shown. The upper subframe 2100A includes a first gusset plate 2102-1 and a second gusset plate 2102-2, which extend downward from the mounting plate 2101 and are laterally spaced by the front plate 2104. The gusset plates 2102-1 and 2102-2 may have an upper front hook 2103 for receiving the front edge of the mounting plate 2101. The gusset plates 2102-1 and 2102-2 may include a gusset tab 2105, which is received in a gusset tab slot 2106 in the mounting plate 2101. Alternatively, an ear plate 2107 having a gusset tab 2109 may be received in the gusset tab slot 2106 in the mounting plate 2101. The ear plate 2107 can be connected via a threaded connector 2108 ( Figure 28 The threaded connector 2108 is attached to the gusset plates 2102-1 and 2102-2, and is received in alignment holes 2110 and 2111 in the respective gusset plates 2102-1, 2102-2 and ear plate 2107. The front plate 2104 may include side tabs 2112, which are received in side tab slots 2113 in the gusset plates 2102-1 and 2102-2. It should be understood that the various parts of the upper subframe 2100A are not connected using tabs and slots, but rather by welding or by bolted connections. Alternatively, the upper subframe 2100A may be manufactured as a single part, for example, by casting.

[0142] The front panel 2104 includes an aperture 2114 through which the upper connector (nipple) of the airbag 2302 extends and threadably receives a fitting 2126 (discussed later). Brackets 2102-1, 2102-2 include apertures 2004 for receiving a threaded connector 2002 for pivotally securing the intermediate subframe 2100B to the brackets 2102-1, 2102-2, as referenced above. Figure 28 As described above. Additionally, each of the gusset plates 2102-1 and 2102-2 includes an aperture 2012 for receiving a threaded connector 2010, for pivotally securing the first link 2200-1 and the second link 2200-2 to the gusset plates 2102-1 and 2102-2, as referred to above. Figure 28 As described above, each of the gusset plates 2102-1 and 2102-2 also includes an aperture 2033 for receiving a threaded connector 2032, which secures the U-shaped bracket of the spring assembly 2310 (discussed later). Furthermore, each of the gusset plates 2102-1 and 2102-2 also includes an arcuate opening 2037 in which the threaded connector 2036 is movable, as referenced above. Figure 28 As described.

[0143] Figure 30 An exploded rear perspective view of the intermediate subframe 2100B is shown. The intermediate subframe 2100B includes a base member 2120 and a first side guide rail 2121-1 and a second side guide rail 2121-2. The base member 2120 may include a side tab 2122 received within a side tab recess 2123 in the side guide rails 2121-1 and 2121-2. The base member 2120 includes an aperture 2124 through which a threaded connector 2125 extends. Figure 28 This is used to secure the lower end of the airbag 2302 to the base member 2120. It should be understood that the individual parts of the intermediate subframe 2100B are not connected using tabs and slots, but rather by welding or bolted connections. Alternatively, the intermediate subframe 2100B can be manufactured as a single part, for example, by casting. Each of the side rails 2121-1, 2121-2 includes a front aperture 2003 for receiving a threaded connector 2002, for pivotally securing the side rails 2121-1, 2121-2 of the intermediate subframe 2100B to the corner plates 2102-1, 2102-2 of the upper subframe 2100A, as referred to above. Figure 28 As described above, each of the side rails 2121-1 and 2121-2 includes a rear aperture 2007 for receiving a threaded connector 2006, as referenced above. Figure 28 As described above, each of the side rails 2121-1 and 2121-2 includes an aperture 2029 for receiving a threaded connector 2028 and a rod for attaching a spring assembly 2310 (discussed later). Each of the side rails 2121-1 and 2121-2 includes an aperture 2038 for receiving a threaded connector 2036, which is received within an arcuate opening 2037 of the upper subframe 2100A, as referred to above. Figure 28 As described.

[0144] Figure 31An exploded rear perspective view of the lower subframe 2100C is shown. The lower subframe 2100C includes a first auger wheel support arm 2130-1 and a second auger wheel support arm 2130-2, which are connected at their front ends by a front plate 2132. The front plate 2132 may include side tabs 2133 received within side tab slots 2134 in the first auger wheel support arm 2130-1 and the second auger wheel support arm 2130-2. It should be understood that the individual parts of the lower subframe 2100C are not connected using tabs and slots, but rather by welding or by bolted connections. Alternatively, the lower subframe 2100C may be manufactured as a single part, for example, by casting. Each of the first clearer wheel support arm 2130-1 and the second clearer wheel support arm 2130-2 includes a square opening 2135 for receiving clearer wheel axle bolts 2061-1, 2061-2. Figure 27 The corresponding square handle portion 2063 in ) Figure 27 (This will be discussed in more detail later.) Each cleaning wheel support arm 2130-1, 2130-2 also includes an opening 2022 for receiving the guide wheel shaft bolt 2051, as shown below. Figure 28 As shown. Each cleaning wheel support arm 2130-1, 2130-2 also includes an elongated opening 2009 in which a threaded connector 2006 is received, as referenced above. Figure 28 As described above. Each cleaning wheel support arm 2130-1, 2130-2 also includes an arcuate slot 2019 for receiving the threaded connector 2018, as referenced above. Figure 28 As described above. Each ridge clearer wheel support arm 2130-1, 2130-2 also includes an aperture 2025 for receiving a finger screw 2024, as referred to above. Figure 28 As described.

[0145] Figure 32 This is a rear perspective view of the rear support subframe 2100D. The rear support subframe 2100D includes a first support 2140-1 and a second support 2140-2 spaced apart by side plates 2142. The side plates 2142 may include tabs 2143 received within slots 2144 in each of the first support 2140-1 and the second support 2140-2. Alternatively, the side plates 2142 may be attached to the supports 2140-1 and 2140-2 by welding or bolting. Alternatively, the supports 2140-1, 2140-2 and the side plates 2142 may be manufactured as a single part, for example, by casting. Each of the first support 2140-1 and the second support 2140-2 includes an aperture 2022 aligned with an aperture 2023 in the lower subframe 2100C for receiving wheel bolts 2051, as referenced above. Figure 28As described above. Each of the support rods 2140-1 and 2140-2 further includes: an aperture 2008 through which a threaded connector 2006 extends; and an aperture 2016 for receiving a threaded connector 2014; and an internal thread aperture 2021 for receiving a threaded connector 2018; and a series of apertures 2026 arranged in an arc, through which the pin end of a finger screw 2024 is received, as referred to above. Figure 28 As described.

[0146] The rear strut subframe 2100D may include a scraper 2145 to remove dirt or debris that may accumulate on the guide roller 2050 during operation. The scraper 2145 may be attached to a side plate 2142 between the rear struts 2140-1 and 2140-2 of the rear strut subframe 2100D, and may include a plate with a curved edge 2146 that approximates the contour of the guide roller 2050 (see [link to documentation]). Figure 19 The scraper 2145 can be attached to the side plate 2142 by means of a threaded connector 2148 extending through an elongated hole 2147 that aligns with an internally threaded aperture 2149 in the side plate 2142. The elongated hole 2147 allows the scraper 2145 to be adjusted relative to the side plate 2142 to change the distance from the guide wheel 2050 to accommodate different guide wheel sizes and profiles, as well as to take into account wear on the guide wheel surface and the scraper 2145.

[0147] Reference Figure 27The square opening 2135 in each of the cleaner wheel support arms 2130-1, 2130-2 and the square shank portion 2063 of the cleaner wheel axle bolts 2061-1, 2061-2 cooperate to rotatably constrain the cleaner wheel axle bolts 2061-1, 2061-2 to the cleaner wheel support arms 2130-1, 2130-2. Each cleaner wheel axle bolt 2061-1, 2061-2 receives a spacer 2063. Each cleaner wheel axle bolt 2061-1, 2061-2 extends through a central opening 2064 within each of the corresponding first cleaner wheel 2060-1 and second cleaner wheel 2060-2. A bushing 2065 is received at the end of each cleaner wheel axle bolt 2061-1, 2061-2, and the bushing is received within a hub 2070 having a central opening 2071. Hub 2070 is secured to the corresponding first clearer wheel 2060-1 and second clearer wheel 2060-2 by nuts 2072, which are threadably received on threaded connector 2074, which extends through orifices 2066 in clearer wheels 2060-1 and 2060-2 and through alignment holes 2073 in hub 2070. Lug nuts 2075 threadably receive the ends of axle bolts 2061-2 and 2061-2, thereby axially constraining clearer wheels 2060-1 and 2060-2 to the corresponding clearer wheel axle bolts 2061-2 and 2061-2, while spacers 2063 and bushings 2065 allow clearer wheels 2060-1 and 2060-2 to rotate freely about the corresponding clearer wheel axle bolts 2061-2 and 2061-2.

[0148] Return to reference Figure 19 and Figure 28 The guide wheel shaft bolt 2051 passes through the alignment holes 2022, 2023 in the corresponding first clearer wheel support arm 2130-1 and second clearer wheel support arm 2130-2 of the lower subframe 2100C with the supports 2140-1, 2140-2 of the rear support subframe 2100D and through the hub 2052 of the guide wheel 2050. Figure 19 ) extension. Spacer bushing 2053 ( Figure 28 A guide wheel 2050 can be mounted on a guide wheel shaft bolt 2051 on each side of the hub 2052 to keep the guide wheel 2050 centered between the supports 2140-1 and 2140-2. A nut 2054 is threaded onto the end of the guide wheel shaft bolt 2051, thereby securing the guide wheel 2050 to the lower subframe 2100C and the rear support subframe 2100D.

[0149] Figure 33 This is an exploded perspective view of the actuator system 2300, including the airbag 2302 and the spring assembly 2310. (Refer to...) Figure 29Combined Figure 33 The airbag 2302 is secured at its upper end by a fitting 2126, which threadedly receives a connector 2127 extending through an opening 2114 in the front plate 2040 of the upper subframe 2100A. (Refer to...) Figure 28 and Figure 30 Combined Figure 33 The airbag 2302 is secured at its lower end by a threaded connector 2125, which extends through an aperture 2124 in the base member 2120 of the intermediate subframe 2100B. (Refer to...) Figure 27 , Figure 28 and Figure 29 Combined Figure 33 The spring assembly 2310 is fixed to the intermediate subframe 2100B and received between the gusset plates 2102-1 and 2102-2 of the upper subframe 2100A, in front of the front plate 2104 and in front of the airbag 2302. The spring assembly 2310 includes a rod 2312 having an internally threaded orifice 2030 in which a threaded connector 2028 is received, as referenced above. Figure 28 As described. A transverse bore 2314 passes transversely through rod 2312, perpendicular to the longitudinal axis of the rod. Rod 2312 includes a transverse channel 2316 sized to receive the head of bolt 2318 to prevent rotation of bolt 2318. The shaft of bolt 2318 passes through orifice 2319 in U-shaped bracket 2320. The upwardly rotating end of U-shaped bracket 2320 includes orifice 2034, which receives threaded connector 2032, as described above. Figure 28 As described. Bolt 2318's shaft receives collar 2322. Spring 2324 sits on collar 2322. The upper end of bolt 2318 receives washer 2326 and threadably receives nut 2328. It should be understood that because rod 2312 is fixed to intermediate subframe 2100B and U-shaped bracket 2320 is fixed to upper subframe 2100A, when nut 2327 is tightened onto bolt 2317, spring 2325 is compressed, tending towards a clockwise direction (e.g., ...). Figure 28As shown, the intermediate subframe 2100B pivots about an axis passing through a threaded connector 2002, which pivotally secures the front end of the intermediate subframe 2100B to the upper subframe 2100A. Therefore, it should be understood that the spring assembly 2310 serves to provide an upward force at the rear end of the intermediate subframe 2100B (and thus provide the upward force to the lower subframe 2100C and the rear support subframe 2100D). The compression of the spring 2325 increases the upward force on the intermediate subframe 2100B by tightening the nut 2327 onto the bolt 2317. The amount of upward force can be reduced by loosening the nut 2327 on the bolt 2317. In one embodiment, the amount of upward force provided by the spring assembly is sufficient to lift the clearer wheels 2060-1, 2060-2 away from contact with the soil 40. Although the spring assembly 2310 is shown as having two springs 2325, it can be constructed from a single spring 2325, which is received on a single bolt 2317 positioned at the midpoint of the rod 2312. On the other hand, the airbag 2302 applies downward pressure to the intermediate subframe 2100B to counteract the upward force of the spring assembly 2310. By increasing and decreasing the air pressure in the airbag 2302, causing it to expand and contract respectively, the desired amount of downward pressure applied to the guide wheel 2050 and the cleaning wheels 2060-1, 2060-2 can be achieved.

[0150] While the above embodiments of actuator system 2300 describe an airbag 1302 combined with spring assembly 2310, it should be understood that actuator system 2300 may utilize any actuator providing adjustable downforce and optional upforce. The downforce applied to guide wheel 2050 by actuator system 2302 may be controlled by a controller (e.g., “Controller 300” referenced in U.S. Patent No. 8,550,020) or by a fluid control port (e.g., “Fluid Control Port 10” described in PCT Publication No. WO2020 / 056395). The actuators 2302 of each clearer assembly 2000 of planter 10 may be controlled row by row, or by portions of planter 10 as a group, or collectively across the entire planter 10.

[0151] The desired amount of downforce can be a function of soil conditions and the amount or type of crop residue, as well as the depth to which the ridging wheel 2060 engages with the soil. For example, under dry soil conditions, greater downforce can be expected, causing the guide wheel 2050 to more firmly pack the soil 40 in front of the opening assembly 234 for better seed furrow 38 formation and to prevent or minimize soil falling into the seed furrow 38 before seeds are deposited. Alternatively, under wet soil conditions, less downforce can be expected. A downforce monitoring system (discussed later) can be used to determine and adjust the downforce applied by the actuator system 2300.

[0152] Figure 34 This is a side view of the planting machine ridge unit 200, as previously referred to above. Figure 2 This is yet another embodiment, but with the ridge clearer assembly designated by reference numeral 3000. The ridge clearer assembly 3000 is mounted to the tool bar 14 and positioned in front of the furrowing assembly 234. Again, it should be understood that each ridge unit 200 of the planter 10 will have an associated ridge clearer assembly 3000, which is longitudinally aligned with the corresponding furrowing assembly 234 of the ridge unit 200. In the illustrated embodiment, the ridge clearer assembly 3000 includes guide wheels 3050 (e.g., ...). Figure 35 (As shown). The clearer assembly 3000 extends toward the rear of the tool bar 14 and is rigidly mounted to the underside of the tool bar 14 by a suitable mounting structure, which may include a mounting plate 3101 and one or more U-bolts 3001, as shown. Alternatively, the clearer assembly 3000 can be mounted to the top, rear, or front side of the tool bar 14 by any suitable mounting structure or connector (including bolt brackets or by welding).

[0153] Figure 34A Alternative embodiments of the clearer assembly designated by reference numeral 3000A are shown. The embodiment of clearer assembly 3000A is substantially the same as the embodiment of clearer assembly 3000, except that the embodiment of 3000A does not include the guide wheel 3050. Furthermore, the embodiment of 3000A may omit the rear support subframe 3100B (described later).

[0154] Figure 35 yes Figure 34 An enlarged rear perspective view of the cleaning unit 3000 shown. Figure 35A The view and Figure 35The views are the same, but an embodiment of the clearer assembly 3000A (discussed later) is shown without the guide wheel and the rear support subframe 3100D. Since the two embodiments of clearer assemblies 3000 and 3000A are substantially the same, only embodiment 3000 will be described, except that the guide wheel (and optionally the rear support subframe 3100D, discussed later) is removed in embodiment 3000A. It should be understood that any references to the guide wheel 3050, guide wheel shaft 3051, and associated components will not apply to embodiment 3000A.

[0155] Figure 36 and Figure 37 These are the right and left views of the cleaning unit 3000. Figure 38 and Figure 39 These are the front view and the rear view, respectively. Figure 40 and Figure 41 These are top and bottom views, respectively. The ridging assembly 3000 includes a frame assembly 3100 supported at its rear end by guide wheels 3050. Riddler wheels 3060-1 and 3060-2 are rotatably supported by the frame assembly 3100. Each ridging wheel 3060-1 and 3060-2 includes radially spaced teeth 3062 around its circumference. The ridging wheels 3060-1 and 3060-2 are oriented outward and rearward, such that the teeth 3062 of the ridging wheels 3060-1 and 3060-2 are interlaced at their front ends as they rotate. In operation, as the planter 10 moves in the forward direction 11, the soil engages with the teeth 3062, causing the ridging wheels 3060-1 and 3060-2 to rotate. Due to their orientation, as the ridging wheels 3060-1 and 3060-2 rotate, they guide any crop residue, clods of soil, or other debris laterally outward to provide a ridging bed for the rearward-aligned furrowing assembly 234. Before the furrow 38 is opened by the furrowing assembly 234, the guide wheel 3050 is used to compact the soil 40 that will be disturbed by the ridging wheels 3060-1 and 3060-2. Compacting the soil with the guide wheel 3050 in dry soil helps prevent soil 40 from falling into the furrow 38.

[0156] An actuator system 3300 is positioned within the frame assembly 3100 to provide adjustable downforce and optional upforce to the guide wheel 3050 and the cleaning wheels 3060-1, 3060-2. In this embodiment, the actuator system 3300 utilizes two airbags 3302 and 3304 ( Figure 45 However, the actuator system 3300 can utilize any actuator that provides adjustable downforce and optional upforce, including pneumatic cylinders, hydraulic cylinders, airbags, and electromechanical actuators, as will be discussed in more detail later.

[0157] Figure 42This is a rear perspective view of the frame assembly 3100. For clarity, the guide wheel 3050, the cleaning wheel 3060-1, 3060-2, and the actuator system 3300 have been removed. Figure 43 This is a front perspective view of the frame assembly 3100 with the guide wheel 3050, actuator system 3300, and first clearer wheel 3060-1 removed, but an exploded view of the second clearer wheel 3060-2 and its mounting components is shown. Figure 44 This is the rear perspective view of the exploded frame component 3100. (Refer to...) Figures 42 to 44 The frame assembly 3100 includes an upper subframe 3100A, a middle subframe 3100B, a lower subframe 3100C, a rear support subframe 3100D, a first link 3200-1, and a second link 3200-2. The rear support subframe 3100D includes a portion of the lower subframe 3100C. Figure 45 This is an exploded front perspective view showing the lower subframe 3100C and the rear support subframe 3100D. Figure 46 A perspective view of the intermediate subframe 3100B and connecting rods 3200-1 and 3200-2 is shown. For clarity, the first airbag 3302 and the second airbag 3304 of the actuator assembly 3300 are shown in dashed lines. Subframes 3100A, 3100B, 3100C, 3100D and connecting rods 3200-1 and 3200-2 will be described in more detail later.

[0158] like Figure 44As best shown, the intermediate subframe 3100B is pivotally connected at its front end to the upper subframe 3100A via a threaded connector 3002 received in alignment apertures 3003, 3004 in the respective intermediate subframe 3100B and the upper subframe 3100A. The threaded connector 3002 and apertures 3003, 3004 can be threaded together as shown in the previous embodiments 1000, 2000. Alternatively, as shown, aperture 2003 in the intermediate subframe 3100B can be a square aperture receiving the square shank portion of the threaded connector 3002. The aperture 3004 in the upper subframe 3100A can be sized to receive a sleeve 3009 and a collapsed bushing 3010, which are retained by a nut 3011 received at the threaded end of the threaded connector 3002. The intermediate subframe 3100B is pivotally connected at its rear end by a threaded connector 3006 received in orifices 3007, 3008 in the respective intermediate subframe 3100B and in the lower subframe 3100C. The threaded connector 3006 and orifices 3007, 3008 can be threaded together as shown in the previous embodiments 1000, 2000. Alternatively, as shown, the orifice 3008 in the lower subframe 3100C can be a square orifice receiving the square shank portion of the threaded connector 3006. The orifice 3007 in the intermediate subframe 3100B can be sized to receive a sleeve 3009 and a bushing 3010, which are retained by a nut 3011 received at the threaded end of the threaded connector 3006.

[0159] The first link 3200-1 and the second link 3200-2 are pivotally connected at their front ends to the upper subframe 3100A via threaded connectors 3012 received in alignment openings 3013, 3014 in the respective first link 3200-1 and second link 3200-2. The threaded connectors 3012 and the openings 3013, 3014 can be threaded together as shown in the previous embodiments 1000, 2000. Alternatively, as shown, the opening 3014 in the upper subframe 3100A can be a square opening that receives the square shank portion of the threaded connector 3012. The orifice 3013 in the first link 3200-1 and the second link 3200-2 can be sized to receive a sleeve 3009 and a bushing 3010, which are retained by a nut 3011 received at the threaded end of a threaded connector 3012. The first link 3200-1 and the second link 3200-2 are pivotally connected at their rear ends to the lower subframe 3100C via threaded connectors 3016 received in aligned orifices 3017 and 3018 in the respective first link 3200-1 and second link 3200-2. The threaded connectors 3016 and orifices 3017 and 3018 can be threaded together as shown in the previous embodiments 1000 and 2000. Alternatively, as shown in the figure, the aperture 3017 in the lower subframe 3100C can be a square aperture that receives the square shank portion of the threaded connector 3016. The apertures 3018 in the first link 3200-1 and the second link 3200-2 can be sized to receive a sleeve 3009 and a bushing 3010, which are retained by a nut 3011 received at the threaded end of the threaded connector 3016.

[0160] The rear support subframe 3100D is aligned with the lower subframe 3100C via alignment holes 3025, 3026 (see...). Figure 45 The threaded connector 3024 received within the subframe 3100C is pivotally connected. (As shown) Figure 43 and Figure 45As best shown, the rear support subframe 3100D is also linked to the lower subframe 3100C via the hook arm 3402 of the depth selector 3400 (discussed later). It should be understood that the forward pivoting connection of the upper subframe 3100A with the intermediate subframe 3100B and links 3200-1, 3200-2, together with the rearward pivoting connection of the intermediate subframe 3100B and links 3200-1, 3200-2 with the lower subframe 3100C, provides a four-bar linkage that allows the intermediate subframe 3100B and lower subframe 3100C to move vertically relative to the upper subframe 3100A, which is rigidly fixed to the tool bar 14. It should be apparent that in the 3000A embodiment, the entire rear support subframe 3100D can be omitted, as the primary purpose of the rear support subframe 3100D is to support the guide wheel 3050, which is absent in the 3000A embodiment. However, as explained in detail later, the rear support subframe 3100D cooperates with the lower subframe 3100C to achieve depth selection via the depth selector 3400. Therefore, if depth selection is desired, an embodiment of the clearer assembly 3000A can be used with the rear support subframe 3100D, thereby omitting only the guide wheel 3050 and guide wheel shaft bolt 3051.

[0161] Figure 47 An exploded front perspective view of the upper subframe 3100A is shown. The upper subframe 3100A includes a first gusset plate 3102-1 and a second gusset plate 3102-2, which extend downward from the mounting plate 3101 and are laterally spaced from the front plate 3104. The gusset plates 3102-1 and 3102-2 may respectively include apertures 3004 and 3014 for receiving threaded connectors 3002 and 3012, for attaching the intermediate subframe 3100B and guide rails 3200-1 and 3200-2, as referenced above. Figure 44 As described. The front plate 3104 may include side tabs 3105 received within side tab slots 3106 in the gusset plates 3102-1, 3102-2. The front plate 3104 includes a recess 3107 to accommodate insertion of a threaded connector 3012 into an aperture 3014 in the gusset plates 3102-1, 3102-2. The connecting plate 3108 includes an upper tab 3109 received within a tab slot 3110 in the mounting plate 3101. The connecting plate 3108 also includes a bottom hook 3111 receiving and engaging the rear edge and recessed area of ​​the front plate 3104. It should be understood that the individual parts of the upper subframe 3100A are not connected using tabs and slots, but rather by welding or by bolted connections. Alternatively, the upper subframe 3100A may be manufactured as a single part, for example, by casting.

[0162] Figure 48An exploded rear perspective view of the intermediate subframe 3100B is shown. The intermediate subframe 3100B includes a front base member 3120 and a rear base member 3122, as well as a first side guide rail 3121-1 and a second side guide rail 3121-2. The base members 3120, 3122 may include side tabs 3123, which are received within side tab recesses 3124 in the side guide rails 3121-1, 3121-2. It should be understood that the individual parts of the intermediate subframe 3100B are not connected using tabs and slots, but rather by welding or by bolted connections. Alternatively, the intermediate subframe 3100B may be manufactured as a single part, for example, by casting. The front base member 3120 includes an aperture 3125 through which the connector of the first airbag 3302 extends and receives a fitting 3126. Figure 43 The accessory 3126 threadably secures the second airbag 3304 to the front base member 3120. The rear base member 3122 includes an aperture 3127 through which the connector of the first airbag actuator 3302 extends and receives the accessory 3128. Figure 46 The accessory 3128 threadably secures the first airbag 3302 to the rear base member 3122. Each of the side rails 3121-1 and 3121-2 includes a front opening 3003 for receiving a threaded connector 3002 for pivotally securing the side rails 3121-1 and 3121-2 of the intermediate subframe 3100B to the corner plates 3102-1 and 3102-2 of the upper subframe 3100A, as referred to above. Figure 44 As described above, each of the side rails 3121-1 and 3121-2 includes a rear aperture 3007 for receiving a threaded connector 3006, as referenced above. Figure 44 As described.

[0163] Figure 49An exploded rear perspective view of the first link 3200-1 and the second link 3200-2 is shown. The first link 3200-1 and the second link 3200-2 can be connected via a front plate 3202 and a rear plate 3204. Each of the front plate 3202 and the rear plate 3204 may include a side tab 3203 received within a side tab recess 3205 in the links 3200-1 and 3200-2. A stiffening plate 3206 may be provided to reinforce the front plate 3202. The stiffening plate 3206 may include a tab 3207 received within a tab slot 3208 in the front plate 3202 and the links 3200-1 and 3200-2. It should be understood that the various parts of the intermediate subframe 3100B are not connected using tabs and slots, but rather by welding or by bolted connections. Alternatively, the intermediate subframe 3100B can be manufactured as a single part, for example, by casting. The front panel member 3202 may include an aperture 3210 for receiving a threaded connector (not shown) for attaching the first airbag actuator 3302 and the second airbag actuator 3304 to the front panel member 3202 (see [link to documentation]). Figure 46 ).

[0164] Figure 50 An exploded rear perspective view of the lower subframe 3100C is shown. The lower subframe 3100C includes a first mandator wheel support arm 3130-1 and a second mandator wheel support arm 3130-2, which are connected at their front ends by a front plate 3132. The front plate 3132 may include side tabs 3133 received within side tab slots 3134 in the first mandator wheel support arm 3130-1 and the second mandator wheel support arm 3130-2. A rear plate 3136 may be configured to laterally constrain the rear ends of the mandator wheel support arms 3130-1 and 3130-2. The rear plate 3136 may include side tabs 3137 received within side tab slots 3138 in the mandator wheel support arms 3130-1 and 3130-2. It should be understood that the components of the lower subframe 3100C are not connected using tabs and slots, but rather by welding or bolted connections. Alternatively, the lower subframe 3100C can be manufactured as a single part, for example, by casting. Each of the cleaning wheel support arms 3130-1, 3130-2 also includes an opening 3026 that aligns with an aperture 3025 in the rear support subframe 3100D for receiving a threaded connector 3024, for pivotally attaching the lower subframe 3100C to the rear support subframe 3100D (see [link]). Figure 45Each clearer wheel support arm 3130-1, 3130-2 also includes orifices 3008, 3017 for receiving corresponding threaded connectors 3006, 3008 and connecting rods 3200-1, 3200-2 of the corresponding intermediate subframe 3100B, as referred above. Figure 44 As described. Each of the first clearer wheel support arm 3130-1 and the second clearer wheel support arm 3130-2 includes a square opening 3135 for receiving a square shank portion of a corresponding one of the clearer wheel axle bolts 3061-1, 3061-2, as will be discussed in more detail later. The front plate 3132 may include a tab slot 3153 for the depth selector 3400, which will be discussed later.

[0165] Figure 51 This is a rear perspective view of the rear support subframe 3100D. The rear support subframe 3100D includes a first support 3140-1 and a second support 3140-2, which are spaced apart at their rear ends by side plates 3142. The side plates 3142 may include tabs 3143 received within slots 3144 in each of the first support 3140-1 and the second support 3140-2. Alternatively, the side plates 3142 may be attached to the supports 3140-1 and 3140-2 by welding or bolting. Alternatively, the supports 3140-1 and 3140-2 and the side plates 3142 may be manufactured as a single part, for example, by casting. Each of the supports 3140-1 and 3140-2 includes a bore 3022 for receiving a wheel bolt 3051, as referenced above. Figure 44 As described. In this embodiment, each of the supports 3140-1, 3140-2 includes forward-extending arms 3141-1, 3141-2, which are connected at their front ends by a cross member 3152. The cross member 3152 includes an aperture 3153 for the depth selector 3400, which will be discussed later.

[0166] The rear support subframe 3100D may include a scraper 3145 to remove dirt or debris that may accumulate on the guide roller 3050 during operation. The scraper 3145 may be attached to a side plate 3142 between the rear supports 3140-1 and 3140-2 of the rear support subframe 3100D, and may include a plate with an arcuate edge 3146 that approximates the contour of the guide roller 3050 (see [link to relevant documentation]). Figure 35The scraper 3145 can be attached to the side plate 3142 by means of a threaded connector 3148 extending through an elongated hole 3147 that aligns with an internally threaded aperture 3149 in the side plate 3142. The elongated hole 3147 allows the scraper 3145 to be adjusted relative to the side plate 3142 to change the distance from the guide wheel 3050 to accommodate different guide wheel sizes and profiles, and to take into account wear on the guide wheel surface and the scraper 3145.

[0167] Reference Figure 45 The exploded view shows that the depth selector 3400 allows the angle or position of the lower subframe 3100C to be selectively adjusted relative to the rear support subframe 3100D. The depth selector 3400 includes laterally spaced hook arms 3402-1, 3402-2, each hook arm having a plurality of notches 3404 formed on its upper surface. Each of the hook arms 3402-1, 3402-2 can be attached to the lower subframe 3100C via a tab 3405 received within a tab slot 3406 in the front plate 3132 of the lower subframe 3100C. Alternatively, the hook arms 3402-1, 3402-2 can be attached to the lower subframe 3100C by any suitable means, such as welding or bolting. Figure 45 Combined Figure 43 As shown, hook arms 3402-1 and 3402-2 extend from the front cross member 3152 of the rear support subframe 3100D. Each hook arm 3402-1 and 3402-2 includes a front abutment 3408 and a rear abutment 3410. (Refer to...) Figure 43 It should be understood that the abutments 3408 and 3410 engage with the front cross member 3152, limiting the angle of rotation that can be achieved by the lower subframe 3100C about the axis of the threaded connector 3024, which pivotally connects the lower subframe 3100C to the rear strut subframe 3100D. A handle 3412 is attached to a handle shaft 3414. The handle shaft 3414 passes between laterally spaced hook arms 3402-1 and 3402-2 and extends through a collar 3415 and through an aperture 3153 in the front end of the rear strut subframe 3100D. A spring 3416 is received at the end of the handle shaft 3414 and retained by a washer 3417 and a clip 3418. Spring 3416 biases the handle 3412 downward, such that the handle 3412 is received in one of a plurality of recesses 3404 in the upper surface of the hook arms 3402-1, 3402-2.

[0168] To adjust the angle or position of the lower subframe 3100C relative to the rear support subframe (thus increasing or decreasing the depth of penetration into the soil by the tiller wheels 3060-1, 3060-2), the operator grasps the handle 3412 and applies an upward force to compress the spring 3416, disengaging the handle 3412 from the notch 3402. With the handle disengaged from the notch, the operator can pivot the lower subframe 3100C relative to the rear support subframe 3100D about the axis of the threaded connector 3024, thereby pivotally connecting the lower subframe 3100C to the rear support subframe 3100D. Once the lower subframe is at the desired angle or position, the operator releases the upward pressure on the handle 3412, and the spring bias repositions the handle 3412 back into the corresponding notch 3404, thus securely holding the lower subframe 3100C at the desired angle or position relative to the rear support subframe 3100D, corresponding to the desired tiller wheel depth.

[0169] Reference Figure 43 In each of the clearer wheel support arms 3130-1 and 3130-2, the square opening 3135 is configured to receive the square shank portion (not shown, but see) of the clearer wheel axle bolts 3061-1 and 3061-2. Figure 27(As an example). The square opening 3135 cooperates with the square shank portion of the cleaner wheel axle bolts 3061-1, 3061-2 to rotatably constrain the cleaner wheel axle bolts 3061-1, 3061-2 to the cleaner wheel support arms 3130-1, 3130-2. Each cleaner wheel axle bolt 3061-1, 3061-2 extends through a central opening 3064 within each of the respective first cleaner wheel 3060-1 and second cleaner wheel 3060-2. A bushing 3065 is received at the end of each cleaner wheel axle bolt 3061-1, 3061-2, and the bushing is received within a hub 3070 having a central opening 3071. Hub 3070 is secured to the corresponding first clearer wheel 3060-1 and second clearer wheel 3060-2 by nuts 3072, which are threadably received on threaded connector 3074, which extends through orifices 3066 in clearer wheels 3060-1 and 3060-2 and through alignment holes 3073 in hub 3070. Lug nuts 3075 threadably receive the ends of axle bolts 3061-1 and 3061-2, thereby axially constraining clearer wheels 3060-1 and 3060-2 to the corresponding clearer wheel axle bolts 3061-1 and 3061-2, while bushing 3065 allows clearer wheels 3060-1 and 3060-2 to rotate freely about the corresponding clearer wheel axle bolts 3061-1 and 3061-2. Spacers (not shown) can be provided on the shaft bolts 3061-1 and 3061-2 of the purifier to position the purifier wheels 3060-1 and 3060-2 outward away from the purifier wheel support arms 3130-1 and 3130-2. Figure 43 Also shown is a scraper 3076, which can be mounted on the purifier shaft bolts 3061-1, 3061-2 to scrape away dirt or mud from the purifier wheels 3060-1, 3060-2 as they rotate.

[0170] Reference Figure 35 and Figure 44 The guide wheel shaft bolt 3051 passes through the hole 3022 in the rear support subframe 3100D and through the hub 3052 of the guide wheel 3050. Figure 35 ) extension. Spacer bushing 3053 ( Figure 44 The guide wheel 3050 can be mounted on the guide wheel shaft bolt 3051 on each side of the hub 3052 to keep the guide wheel 3050 centered between the supports 3040-1 and 3040-2. The nut 3054 is threaded onto the end of the guide wheel shaft bolt 3051 to secure the guide wheel 3050 to the rear support subframe 3100D.

[0171] Reference Figure 44 and Figure 46The actuator system 3300 may include a first airbag 3302 and a second airbag 3304, which are disposed within the intermediate subframe 3100B and cooperate with links 3200-1 and 3200-2. The first airbag 3302 is connected at its rear end to the rear plate 3122 of the intermediate subframe 3100B behind the second airbag 3304, and at its front end to a side plate 3202 between the first link 3200-1 and the second link 3200-2. The second airbag 3404 is connected at its rear end to the same side plate 3202, and at its front end to the front plate 3120 of the intermediate subframe 3100B. As shown schematically in Figure 52A, as the pressure in the first or rear airbag 3302 increases, causing the first or rear airbag 3302 to inflate and the second or front airbag 3404 to collapse, downward pressure and downward rotational motion are applied, as indicated by the directional arrows in Figure 52A. This downward pressure on the lower subframe 3100C and the rear support subframe 3100D (indicated by dashed lines relative to the solid lines) causes the guide wheel 3050 and the clearing wheel 3060-1, 3060-2 to move downward or apply greater downward pressure to the soil 40. Conversely, as schematically shown in Figure 52B, the increased pressure in the second and front airbags 3404 causes them to expand and the first or rear airbag 3302 to collapse, applying an upward force and an upward rotational motion, as indicated by the directional arrows in Figure 52B. This pressurizes the lower subframe 3100C and the rear support subframe 3100D (indicated by dashed lines relative to the solid lines), causing the guide wheel 3050 and the clearing wheels 3060-1, 3060-2 to move upward or apply a smaller downward pressure to the soil 40. Therefore, it should be understood that by increasing and decreasing the air pressure in the first airbag 3302 and the second airbag 3304, causing them to expand and contract respectively, the desired amount of downward pressure applied to the guide wheel 3050 and the clearing wheels 3060-1, 3060-2 can be achieved.

[0172] The first actuator 3302 and the second actuator 3304 can be any type of single-acting or double-acting actuator, which can be configured to provide adjustable downforce and optional upforce, including pneumatic cylinders, hydraulic cylinders, airbags, and electromechanical actuators, instead of the airbag used for actuator system 3300. In some other embodiments, a single-acting actuator, such as an airbag and a front spring assembly, similar to the spring assembly 2300 described above with respect to embodiment 2000 of the second clearer assembly, can be utilized. The downforce applied by actuator system 3300 to guide wheel 3050 and clearer wheels 3060-1, 3060-2 can be controlled by a controller (e.g., “Controller 300” referenced in U.S. Patent No. 8,550,020) or by a fluid control port (e.g., “Fluid Control Port 10” described in PCT Publication No. WO2300 / 056395). The actuator system 3300 of each clearer assembly 3000 of the planter 10 can be controlled row by row, or controlled by a portion of the planter 10 as a group, or collectively controlled on the entire planter 10.

[0173] The desired amount of downforce can be a function of soil conditions and the amount or type of crop residue, as well as the depth to which the ridging wheel 3060 engages with the soil. For example, under dry soil conditions, greater downforce can be expected, causing the guide wheel 3050 to more firmly pack the soil 40 in front of the opening assembly 234 for better seed furrow 38 formation and to prevent or minimize soil falling into the seed furrow 38 before seeds are deposited. Alternatively, under wet soil conditions, less downforce can be expected. A downforce monitoring system (discussed later) can be used to determine and adjust the downforce applied by the actuator system 3300.

[0174] Figure 53 This is a side view of the planting machine ridge unit 200, as previously referred to above. Figure 2 This is yet another embodiment, but with the ridge clearer assembly designated by reference numeral 4000. The ridge clearer assembly 4000 is mounted to the tool bar 14 and positioned in front of the furrowing assembly 234. Again, it should be understood that each ridge unit 200 of the planter 10 will have an associated ridge clearer assembly 4000, which is longitudinally aligned with the corresponding furrowing assembly 234 of the ridge unit 200. In the illustrated embodiment, the ridge clearer assembly 4000 includes guide wheels 4050 (e.g., ...). Figure 54(As shown). The row clearer assembly 4000 extends toward the rear of the tool bar 14 and is rigidly mounted to the front of the tool bar 14 by a suitable mounting structure, which may include a pair of mounting brackets 4101 bolted to a plate or gusset plate fixed to the tool bar 14. Alternatively, the row clearer assembly 4000 may be mounted to the top, rear, or underside of the tool bar 14 by any suitable mounting structure or connector (including bolted brackets or by welding).

[0175] Figure 53A Alternative embodiments of the clearer assembly designated by reference numeral 4000A are shown. The embodiment of clearer assembly 4000A is substantially the same as the embodiment of clearer assembly 4000, except that the embodiment of 4000A does not include the guide wheel 4050. Furthermore, the embodiment of 4000A may omit the rear support subframe 4100B (described later).

[0176] Figure 54 yes Figure 53 An enlarged rear perspective view of the cleaning unit 4000 shown. Figure 54A The view and Figure 54 The views are the same, but an embodiment of the clearer assembly 4000A (discussed later) is shown without the guide wheel 4050 and the rear support subframe 4100D. Since the two embodiments of clearer assemblies 4000 and 4000A are substantially the same, only embodiment 4000 will be described, except that the guide wheel (and optionally the rear support subframe 4100D, discussed later) is removed in embodiment 4000A. It should be understood that any references to the guide wheel 4050, guide wheel shaft 4051, and associated components will not apply to embodiment 4000A.

[0177] Figure 55 and Figure 56 These are the right and left views of the cleaning unit 4000. Figure 57 and Figure 58 These are the front view and the rear view, respectively. Figure 59 and Figure 60These are top and bottom views, respectively. The ridging assembly 4000 includes a frame assembly 4100 supported at its rear end by guide wheels 4050. Riddler wheels 4060-1 and 4060-2 are rotatably supported by the frame assembly 4100. Each ridging wheel 4060-1 and 4060-2 includes radially spaced teeth 4062 around its circumference. The ridging wheels 4060-1 and 4060-2 are oriented outward and rearward, such that the teeth 4062 of the ridging wheels 4060-1 and 4060-2 are interlaced at their front ends as they rotate. In operation, as the planter 10 moves in the forward direction 11, the soil engages with the teeth 4062, causing the ridging wheels 4060-1 and 4060-2 to rotate. Due to their orientation, as the ridging wheels 4060-1 and 4060-2 rotate, they guide any crop residue, clods of soil, or other debris laterally outward to provide a ridging bed for the rearward-aligned furrowing assembly 234. Before the furrow 38 is opened by the furrowing assembly 234, the guide wheel 4050 is used to compact the soil 40 that will be disturbed by the ridging wheels 4060-1 and 4060-2. Compacting the soil with the guide wheel 4050 in dry soil helps prevent soil 40 from falling into the furrow 38.

[0178] An actuator system 4300 is positioned within the frame assembly 4100 to provide adjustable downforce and optional upforce to the guide wheel 4050 and the cleaning wheels 4060-1, 4060-2. In this embodiment, the actuator system 4300 utilizes two airbags 4302 and 4304 ( Figure 63 However, the actuator system 4300 can utilize any actuator that provides adjustable downforce and optional upforce, including pneumatic cylinders, hydraulic cylinders, airbags, and electromechanical actuators, as will be discussed in more detail later.

[0179] Figure 61 This is a rear perspective view of frame component 4100. For clarity, guide wheel 4050, cleaning wheel 4060-1, and 4060-2 have been removed. Figure 62 This is a front perspective view of the frame assembly 4100 with the guide wheel 4050, actuator system 4300, and first clearer wheel 4060-1 removed, but an exploded view of the second clearer wheel 4060-2 and its mounting components is shown. Figure 63 This is a rear perspective view of the exploded frame component 4100. See reference 61 to... Figure 64 The frame assembly 4100 includes an upper subframe 4100A, a middle subframe 4100B, a lower subframe 4100C, a rear support subframe 4100D, a first link 4200-1, and a second link 4200-2. The rear support subframe 4100D includes a portion of the lower subframe 4100C. Figure 64This is an exploded front perspective view showing the lower subframe 4100C and the rear support subframe 4100D. Figure 65 The diagram shows a perspective view of the intermediate subframe 3100B and connecting rods 3200-1, 32002 with the first airbag 4302 and the second airbag 4304 of the actuator assembly 4300. Subframes 4100A, 4100B, 4100C, 4100D and connecting rods 4200-1, 4200-2 will be described in more detail later.

[0180] like Figure 63 As best shown, the intermediate subframe 4100B is pivotally connected at its front end to the upper subframe 4100A via a threaded connector 4002 received in alignment apertures 4003, 4004 in the respective intermediate subframe 4100B and the upper subframe 4100A. The threaded connector 4002 and apertures 4003, 4004 can be threaded together as shown in the previous embodiments 1000, 2000. Alternatively, as shown, aperture 4003 in the intermediate subframe 4100B can be a square aperture receiving the square shank portion of the threaded connector 4002. The aperture 4004 in the upper subframe 4100A can be sized to receive a sleeve bushing 4010, which is retained by a nut 4011 received on the threaded end of the threaded connector 4002. The intermediate subframe 4100B is pivotally connected at its rear end by a threaded connector 4006 received in apertures 4007, 4008 in the respective intermediate subframe 4100B and in the lower subframe 4100C. The threaded connector 4006 and apertures 4007, 4008 can be threaded together as shown in the previous embodiments 1000, 2000. Alternatively, as shown, aperture 4007 in the intermediate subframe 4100B can be a square aperture receiving the square shank portion of the threaded connector 4006. The aperture 4008 in the lower subframe 4100C can be sized to receive a sleeve bushing 4010, which is retained by a nut 4011 received on the threaded end of the threaded connector 4006.

[0181] The first link 4200-1 and the second link 4200-2 are pivotally connected at their front ends to the upper subframe 4100A via threaded connectors 4012 received in alignment apertures 4013, 4014 in the respective first link 4200-1 and second link 4200-2 and the upper subframe 4100A. The threaded connectors 4012 and apertures 4013, 4014 can be threaded together as shown in the previous embodiments 1000, 2000. Alternatively, as shown, aperture 4013 in the links 4200-1, 4200-2 can be a square aperture receiving the square shank portion of the threaded connector 4012. The aperture 4014 in the upper subframe 4100A can be sized to receive a sleeve bushing 4010, which is retained by a nut 4011 received on the threaded end of the threaded connector 4012. The first link 4200-1 and the second link 4200-2 are pivotally connected at their rear ends to the lower subframe 4100C via threaded connectors 4016 received in alignment apertures 4017, 4018 in the respective first link 4200-1 and second link 4200-2 and in the lower subframe 4100C. The threaded connectors 4016 and apertures 4017, 4018 can be threaded together as shown in the previous embodiments 1000, 2000. Alternatively, as shown, aperture 4017 in the links 4200-1, 4200-2 can be a square aperture receiving the square shank portion of the threaded connector 4016. The aperture 4018 in the lower subframe 4100C can be sized to receive a sleeve bushing 4010, which is retained by a nut 4011 received on the threaded end of the threaded connector 4016.

[0182] The rear support subframe 4100D is aligned with the lower subframe 4100C via alignment holes 4025, 4026 (see...) Figure 63 The threaded connector 4024 received within the subframe 4100C is pivotally connected. (As shown) Figure 62 and Figure 64As best shown, the rear support subframe 4100D is also linked to the lower subframe 4100C via a depth selector 4400 (discussed later). It should be understood that the forward pivoting connection of the upper subframe 4100A with the intermediate subframe 4100B and links 4200-1, 4200-2, together with the rearward pivoting connection of the intermediate subframe 4100B and links 4200-1, 4200-2 with the lower subframe 4100C, provides a four-bar linkage that allows the intermediate subframe 4100B and lower subframe 4100C to move vertically relative to the upper subframe 4100A, which is rigidly fixed to the tool bar 14. It should be apparent that in the 4000A embodiment, the entire rear support subframe 4100D can be omitted, as the primary purpose of the rear support subframe 4100D is to support the guide wheel 4050, which is absent in the 4000A embodiment. However, as explained in detail later, the rear support subframe 4100D cooperates with the lower subframe 4100C to achieve depth selection via the depth selector 4400. Therefore, if depth selection is desired, an embodiment of the clearer assembly 4000A can be used with the rear support subframe 4100D, thereby omitting only the guide wheel 4050 and guide wheel shaft bolt 4051.

[0183] Figure 66 A front perspective view of the upper subframe 4100A is shown. In this embodiment, the upper subframe 4100A is shown as a monolithic cast component, but it can be made of individual parts connected by tabs and slots, as described in conjunction with embodiments 1000, 2000, and 3000 above, or the individual parts can be connected by welding or by bolted connectors. The upper subframe 4100A includes a first gusset plate 4102-1 and a second gusset plate 4102-2, which extend downward from the top plate or top surface 4101 and are laterally spaced apart by the front plate or surface 4104. The gusset plates 4102-1 and 4102-2 include apertures 4004 and 4014, respectively, for receiving threaded connectors 4002 and 4012, for attaching the intermediate subframe 4100B and guide rails 4200-1 and 4200-2, as referred to above. Figure 63 As described.

[0184] Figure 63 and Figure 68The rear and front perspective views of the intermediate subframe 4100B are shown respectively. Again, in this embodiment, the intermediate subframe 4100B is shown as a monolithic cast component, but it can be made of individual parts connected by tabs and slots, as described in conjunction with embodiments 1000, 2000, and 3000 above, or the individual parts can be connected by welding or by bolted connectors. The intermediate subframe 4100B includes a front base member 4120 and a rear base member 4122, as well as a first side guide rail 4121-1 and a second side guide rail 4121-2. The front base member 4120 includes an aperture 4125 through which the connector of the first airbag 4302 extends and receives the fitting 4126. Figure 62 The accessory 4126 threadably secures the second airbag 4304 to the front base member 4120. The rear base member 4122 includes an opening 4127 through which the connector of the first airbag 4302 extends and receives the accessory 4128. Figure 65 The accessory 4128 threadably secures the first airbag 4302 to the rear base member 4122. Each of the side rails 4121-1, 4121-2 includes a front aperture 4003 for receiving a threaded connector 4002 for pivotally securing the side rails 4121-1, 4121-2 of the intermediate subframe 4100B to the gusset plates 4102-1, 4102-2 of the upper subframe 4100A, as referred to above. Figure 63 As described above, each of the side rails 4121-1 and 4121-2 includes a rear aperture 4007 for receiving a threaded connector 4006, as referenced above. Figure 63 As described.

[0185] Figure 63 and Figure 67Rear and front perspective views of the first link 4200-1 and the second link 4200-2 are shown, respectively. Again, in this embodiment, the first link 4200-1 and the second link 4200-2 are shown as being connected as a single integral component, for example by casting; however, the links can be made of individual parts connected by tabs and slots, as described in conjunction with the above embodiment 3000, or the individual parts can be connected by welding or by bolted connectors. The first link 4200-1 and the second link 4200-2 can be connected by a front plate 4202. The front plate may include an aperture 4203 for receiving a threaded connector (not shown) for attaching the front and rear ends of the first airbag 4302 and the second airbag 4304 to the front plate, respectively. One or more lateral members 4204 may be connected between the first link 4200-1 and the second link 4200-2 to provide structural rigidity. Each of the connecting rods 4200-1 and 4200-2 includes a front aperture 4013 for receiving a threaded connector 4012, for pivotally securing the connecting rods 4200-1 and 4200-2 to the gusset plates 4102-1 and 4102-2 of the upper subframe 4100A, as referenced above. Figure 63 As described above, each of the connecting rods 4200-1 and 4200-2 includes a rear aperture 4017 for receiving a threaded connector 4016, as referenced above. Figure 63 As described.

[0186] Figure 69 A front perspective view of the lower subframe 4100C is shown. Again, in this embodiment, the lower subframe 4100C is shown as a monolithic cast component, but it can be made of individual parts connected by tabs and slots, as described in conjunction with embodiments 1000, 2000, and 3000 above, or the individual parts can be connected by welding or by bolted connectors. The lower subframe 4100C includes a first scourer wheel support arm 4130-1 and a second scourer wheel support arm 4130-2, which are connected at their front ends. A rear lateral member 4134 may extend between the rear ends of the support arms 4120-1 and 4120-2 to provide structural rigidity. An arcuate panel 4138 extends across the scourer wheel support arms 4130-1 and 4130-2 toward their front ends. The arcuate panel 4138 includes an opening 4402 with a notch, which will be discussed in more detail later in conjunction with the description of the depth adjuster 4400. Each of the clearer wheel support arms 4130-1 and 4130-2 further includes an opening 4026 aligned with an aperture 4025 in the rear support subframe 4100D for receiving a pin 4024 for pivotally attaching the lower subframe 4100C to the rear support subframe 4100D (see [link]). Figure 64Each clearer wheel support arm 4130-1, 4130-2 also includes orifices 4008, 4018 for receiving corresponding threaded connectors 4006, 4016, for connecting the corresponding intermediate subframe 4100B and connecting rods 4200-1, 4200-2, as described above. Figure 63 As described. Each of the first mandator wheel support arm 4130-1 and the second mandator wheel support arm 4130-2 further includes an aperture 4135 for receiving mandator wheel axle bolts 4061-1, 4061-2. A plurality of apertures 4135 may be provided spaced along the mandator wheel support arms 4130-1, 4130-2 to allow the mandator wheel to be positioned forward or backward as desired, depending on the size or configuration of the mandator wheel. In one embodiment, as... Figure 62 As best shown, an oversized rectangular opening 4155 can be formed or manufactured in the purifier wheel support arms 4130-1, 4130-2 to receive a rectangular bevel washer 4156 having an opening 4135 therein, to receive the purifier wheel axle bolts 4060-1, 4060-2. The bevel washer 4156 can have different bevel pitches, which can be oriented within the rectangular opening to provide different tilt angles (e.g., pitch, roll, or yaw) for the purifier wheel depending on site conditions.

[0187] Figure 70 This is a rear perspective view of the rear support subframe 4100D. Again, in this embodiment, the rear support subframe 4100D is shown as a monolithic cast component, but it can be made of individual parts connected by tabs and slots, as described in conjunction with embodiments 1000, 2000, and 3000 above, or the individual parts can be connected by welding or by bolted connectors. The rear support subframe 4100D includes a first support 4140-1 and a second support 4140-2. A lateral member 4142 may extend between supports 4140-1 and 4140-2. Each of supports 4140-1 and 4140-2 includes a bore 4022 for receiving axle bolts 4051, as referred to above. Figure 63 As described. In this embodiment, each of the supports 4140-1, 4140-2 includes forward-extending arms 4141-1, 4141-2, which are connected at their front ends by longitudinally spaced first and cross members 4152, 4154. The first cross member 4152 includes a first aperture 4153, and the second cross member 4154 includes a second aperture 4155 longitudinally aligned with the first aperture 4153. Apertures 4153 and 4155 are configured to receive a depth selector 4400, which will be discussed later.

[0188] The rear support subframe 4100D may include a scraper 4145 to remove dirt or debris that may accumulate on the guide roller 4050 during operation. The scraper 4145 may be attached to a lateral member 4142 between supports 4140-1 and 4140-2, and may include a plate with an arcuate edge 4146 that approximates the contour of the guide roller 4050 (see [link]). Figure 58 The scraper 4145 can be attached to the side member 4142 by means of bolts 4148, which extend through an aperture 4149 in the side member 4142 and through an elongated hole in the scraper 4147 and are secured by a nut 4150. The elongated hole 4147 allows the scraper 4145 to be adjusted relative to the side member 4142 to change the distance from the guide wheel 4050 to accommodate different guide wheel sizes and profiles and to take into account wear on the guide wheel surface and the scraper 4145.

[0189] Reference Figure 64The exploded view shows that the depth selector 4400 allows the angle or position of the lower subframe 4100C to be selectively adjusted relative to the rear strut subframe 4100D. The depth selector 4400 includes a handle 4404 attached to a base 4406. A shaft 4408 extends downward from the base 4406. The base 4406 also includes downwardly extending, laterally spaced pins 4410 that settle within a notch in an opening 4402 with a notch in an arcuate panel 4138 of the lower subframe 4100C. The shaft 4408 extends through the notched opening 4402 and through a first aperture 4153 in the first and second cross members 4152 and settles in a second aperture 4155 in a second cross member 4154 of the rear strut subframe 4100D. A spring (not shown) is retained on the shaft 4408 between the first cross member 4152 and the second cross member 4154 of the rear strut subframe 4100D. To adjust the angle or position of the lower subframe 3100C relative to the rear support subframe 4100D (thus increasing or decreasing the depth of penetration into the soil by the tiller wheels 4060-1, 4060-2), the operator grasps the handle 4404 and applies an upward force to compress the spring, causing the pin 4410 to disengage from the notch 4402 of the opening 4402. With the pin 4410 disengaged from the notch, the operator can pivot the lower subframe 4100C relative to the rear support subframe 4100D about the axis of pin 4024, thereby pivotally coupling the lower subframe 4100C to the rear support subframe 4100D. Once the lower subframe 4100C is in the desired angle or position, the operator releases the upward pressure on the handle 4404, and the spring bias causes the pin 4410 to reseat in the notch of the notched opening 4402, thereby firmly holding the lower subframe 4100C in the desired angle or position relative to the rear support subframe 4100D, corresponding to the desired depth of the clearer wheel.

[0190] Reference Figure 62The first cleaning wheel 4060-1 and the second cleaning wheel 4060-2 are respectively secured to the first cleaning wheel support arm 4030-1 and the second cleaning wheel support arm 4030-2 of the lower subframe 4100C by cleaning wheel axle bolts 4061-2 and 4061-2. Each cleaning wheel axle bolt 4061-1, 4061-2 extends through a central opening 4064 within each of the corresponding first cleaning wheel 4060-1 and second cleaning wheel 4060-2. A bushing 4065 is received at the end of each cleaning wheel axle bolt 4061-1, 4061-2, and the bushing is received within a hub 4070 having a central opening 4071. The hub 4070 is secured to the corresponding first clearer wheel 4060-1 and second clearer wheel 4060-2 by a nut 4072, the nut 4072 being threadably received on a threaded connector 4074, the threaded connector 4074 extending through an opening 4066 in the clearer wheels 4060-1 and 4060-2 and through an alignment hole 4073 in the hub 4070. Nuts 4075 on the rear side of the purifier wheel support arms 4030-1 and 4030-2 receive the ends of wheel axle bolts 4061-1 and 4061-2, thereby axially constraining the purifier wheels 4060-1 and 4060-2 to the corresponding purifier wheel axle bolts 4061-1 and 4061-2, while bushings 4065 allow the purifier wheels 4060-1 and 4060-2 to rotate freely about the corresponding purifier wheel axle bolts 4061-1 and 4061-2. Spacers 4063 and washers can be provided on the purifier axle bolts 4061-1 and 4061-2 to position the purifier wheels 4060-1 and 4060-2 outward away from the purifier wheel support arms 4130-1 and 4130-2. Figure 62 Also shown is a scraper 4076, which can be mounted on the purifier shaft bolts 4061-1, 4061-2 to scrape away dirt or slurry from the purifier wheels 4060-1, 4060-2 as they rotate.

[0191] Reference Figure 54 and Figure 61 The guide wheel shaft bolt 4051 extends through the hole 4022 in the rear support subframe 4100D and through the hub of the guide wheel 4050. Spacer bushing 4053 ( Figure 61 The guide wheel 4050 can be mounted on the guide wheel shaft bolt 4051 on each side of the hub to keep the guide wheel 4050 centered between the supports 4040-1 and 4040-2. The nut 4054 is threaded onto the end of the guide wheel shaft bolt 4051 to secure the guide wheel 4050 to the rear support subframe 4100D.

[0192] Reference Figure 63 and Figure 65The actuator system 4300 may include a first airbag 4302 and a second airbag 4304, which are disposed within the intermediate subframe 4100B and cooperate with links 4200-1 and 4200-2. The first airbag 4302 is connected at its rear end to the rear plate 4122 of the intermediate subframe 4100B behind the second airbag 4304, and at its front end to a lateral member 4202 between the first link 4200-1 and the second link 4200-2. The second airbag 4304 is connected at its rear end to the same lateral member 4202, and at its front end to the front plate 4120 of the intermediate subframe 4100B. Figure 68 The actuator system 4300 operates with respect to the guide wheel 4050 and the clearer wheels 4060-1, 4060-2, applying downward pressure and upward force in a manner substantially the same as that explained above in conjunction with the embodiment of the clearer assembly 3000, which has been described above with reference to Figures 52A and 52B, and will therefore not be repeated here.

[0193] The first actuator 4302 and the second actuator 4304 can be any type of single-acting or double-acting actuator, which can be configured to provide adjustable downforce and optional upforce, including pneumatic cylinders, hydraulic cylinders, airbags, and electromechanical actuators, instead of the airbag used for actuator system 4300. In some other embodiments, a single-acting actuator, such as an airbag and a front spring assembly, similar to the spring assembly 2300 described above with respect to embodiment 2000 of the second clearer assembly, can be utilized. The downforce applied by actuator system 4300 to guide wheel 4050 and clearer wheels 4060-1, 4060-2 can be controlled by a controller (e.g., “Controller 300” referenced in U.S. Patent No. 8,550,020) or by a fluid control port (e.g., “Fluid Control Port 10” described in PCT Publication No. WO2300 / 056395). The actuator system 4300 of each clearer assembly 4000 of the planter 10 can be controlled row by row, or controlled by a portion of the planter 10 as a group, or collectively controlled on the entire planter 10.

[0194] The desired amount of downforce can be a function of soil conditions and the amount or type of crop residue, as well as the depth to which the ridging wheel 4060 engages with the soil. For example, under dry soil conditions, greater downforce can be expected, causing the guide wheel 4050 to more firmly pack the soil 40 in front of the opening assembly 234 for better seed furrow 38 formation and to prevent or minimize soil falling into the seed furrow 38 before seeds are deposited. Alternatively, under wet soil conditions, less downforce can be expected. A downforce monitoring system (discussed later) can be used to determine and adjust the downforce applied by the actuator system 4300.

[0195] Alternative installation layout

[0196] Figure 71 Alternative mounting arrangements are shown that can be used with any of the embodiments of the clearer assemblies 1000, 1000A, 2000, 2000A, 3000, 3000A, 4000, and 4000A described above. Not as... Figure 2 , Figure 2A , Figure 18 , Figure 18A , Figure 34 , Figure 34A , Figure 53 , Figure 53A As shown, the ridge clearer components 1000, 1000A, 2000, 2000A, 3000, 3000A, 4000, and 4000A are mounted to the tool bar 14. The ridge clearer components 1000, 1000A, 2000, 2000A, 3000, 3000A, 4000, or 4000A can be mounted to the ridge unit frame handle 254, or as shown... Figure 71 The mounting bracket 220 shown is mounted to other structural members of the ridge unit frame 210. Although Figure 71 The embodiment shown is that of using a clearer assembly 1000; however, as will be appreciated by those skilled in the art, the same or similar mounting configurations will be applicable to all embodiments of clearer assemblies 1000, 1000A, 2000, 2000A, 3000, 3000A, 4000, and 4000A. Therefore, separate drawings are not included for each clearer assembly embodiment (the alternative mounting arrangement may be applicable to each of said clearer assembly embodiments), but rather... Figure 71 Include reference numerals corresponding to each of the clearer assemblies 1000, 1000A, 2000, 2000A, 3000, 3000A, 4000, 4000A, to indicate that each of those embodiments can be mounted using the mounting bracket 220.

[0197] Figure 72Another alternative embodiment is shown that can be used with any of the embodiments of the clearer assembly 1000, 1000A, 2000, 2000A, 3000, 3000A, 4000, 4000A described above. In this arrangement, the clearer assembly is generally designated by reference numeral 5000 and is shown as similar to clearer assembly 2000 because the clearer assembly utilizes the same rear support subframe 2100D, lower subframe 2100C, guide wheel 2050, and clearer wheels 2060-1, 2060-2 as clearer embodiment 2000. However, in this embodiment, the upper subframe 2100A, middle subframe 2100B, and connecting rods 2200-1, 2200-2 are removed and replaced with parallel arm connecting rod 5002. Parallel arm link 5002 is pivotally connected at its rear end to ridge unit support 5004, which is attached to ridge unit frame 210. In embodiment 2000, if the intermediate subframe 2100B and links 2200-1, 2200-2 are pivotally connected at one point, at the same point, the front end of parallel arm link 5002 is pivotally attached to rear support subframe 2100D and lower subframe 2100C. Actuator system 2300 is removed and replaced with actuator system 5300, which is connected between support member 5006 and parallel arm link 5002 to provide the desired downforce and optional upforce to guide wheel 2050 and clearer wheels 2060-1, 2060-2. Actuator system 5300 can utilize any actuator that provides adjustable downforce and optional upforce, including pneumatic cylinders, hydraulic cylinders, air bladders, and electromechanical actuators. The downforce and optional upforce applied by actuator system 5300 can be controlled by a controller (e.g., “Controller 300” referenced in U.S. Patent No. 8,550,020) or by a fluid control port (e.g., “Fluid Control Port 10” described in PCT Publication No. WO2020 / 056395). Actuators including actuator system 5300 can be controlled row by row, or grouped by portions of planter 10, or collectively across planter 10.

[0198] Although not described separately, the same or substantially similar modifications can be used with each of the ridge unit components 1000, 1000A, 2000, 2000A, 3000, 3000A, 4000, and 4000A. Instead of separate drawings for each ridge clearer component embodiment (each of which can utilize this alternative embodiment 5000), Figure 72Includes reference numerals corresponding to each of the clearer assemblies 1000, 1000A, 2000, 2000A, 3000, 3000A, 4000, 4000A, to indicate that each of those embodiments can be adapted to utilize, as Figure 72 Alternative embodiments 5000 are shown and described. For example, when using ridge unit assembly 1000 or 1000A, the upper subframe 1100A, the middle subframe 1100B, and the links 1200-1 and 1200-2 can be removed and replaced with parallel arm links 5002, and the actuator system 1300 can be removed and replaced with the actuator system 5300 as described in the preceding paragraphs. Similarly, when using ridge unit assembly 3000, the middle subframe 3100B, and the links 3200-1 and 3200-2 can be removed and replaced with parallel arm links 5002 mounted to the lower subframe 3100C, and the actuator system 3300 can be replaced with the actuator system 5300 as described in the preceding paragraphs. Similarly, when using the ridge unit assembly 3000A (i.e., without the guide wheel 3050), the upper subframe 3100A, the middle subframe 3100B, the connecting rods 3200-1, 3200-2 (and optionally the rear support subframe 3100D) can be removed and replaced with parallel arm connecting rods 5002 mounted to the lower subframe 3100C, and the actuator system 3300 can be replaced with the actuator system 5300 as described in the preceding paragraphs. Likewise, when using the ridge unit assembly 4000, the upper subframe 4100A, the middle subframe 4100B, and the connecting rods 4200-1, 4200-2 can be removed and replaced with parallel arm connecting rods 5002 mounted to the lower subframe 4100C, and the actuator system 4300 can be replaced with the actuator system 5300 as described above. Similarly, when using the ridge unit assembly 4000A (i.e., without the guide wheel 4050), the upper subframe 4100A, the middle subframe 4100B, the connecting rods 4200-1, 4200-2 (and optionally the rear support subframe 4100D) can be removed and replaced with the parallel arm connecting rod 5002 mounted to the lower subframe 4100C, and the actuator system 4300 can be replaced with the actuator system 5300.

[0202] Reference Figure 79 and Figure 80The mounting strip 6080 is configured to be mounted to the lower subframes 1100C, 2100C, 3100C, and 4100C with the threaded connector 6081 extending through an aperture 6082 in the mounting strip 6080, the aperture 6082 being aligned with apertures 1035, 2025, 3025, and 4035 in the corresponding clearer wheel support arms 1130-2, 2130-2, 3130-2, and 4130-2. Nuts 6083 on the rear side of the lower subframes 1100C, 2100C, 3100C, and 4100C receive the threaded connector 6081 to secure the mounting strip 6080 to the lower subframes 1100C, 2100C, 3100C, and 4100C. Mounting strip 6080 includes a rear opening 6084 for mounting the second ridge cleaner wheels 1060-2, 2060-2, 3060-2, 4060-2 to the ridge cleaner wheel support arms 1130-2, 2130-2, 3130-2, 4130-2 of the respective lower subframes 1100C, 2100C, 3100C, 4100C via the second ridge cleaner shaft bolts 1061-2, 2061-2, 3061-2, 4061-2 to the mounting strip 6080. In an alternative embodiment, the mounting strip 6080 may include an enlarged orifice 6086 for aligning and receiving bushings for securing the second clearer wheels 1060-2, 2060-2, 3060-2, 4060-2 to the clearer wheel support arms 1130-2, 2130-2, 3130-2, 4130-2 of the respective lower subframes 1100C, 2100C, 3100C, 4100C. The mounting strip 6080 includes the orifice 6086, which may be an elongated orifice through which a third clearer wheel axle bolt 6061 extends. The third wheel axle bolt 6061 extends through a central opening 6064 of the third clearer wheel 6060. A bushing 6065 is received at the end of the third row clearer wheel axle bolt 6061, and the bushing 6065 is received within a hub 6070 having a central opening 6071. The hub 6070 is secured to the third row clearer wheel 6060 by a nut 6072, which is threadably received on a threaded connector 6074 extending through an aperture 6066 in the third row clearer wheel 6060 and through an alignment hole 6073 in the hub 6070. A nut 6075 on the rear side of the mounting strip 6080 receives the end of the third row clearer wheel axle bolt 6061, thereby axially constraining the third row clearer wheel 6060 to the mounting strip 6080, while the bushing 6065 allows the third row clearer wheel 6060 to rotate freely about the corresponding clearer wheel axle bolt 6061.Spacers and washers (not shown) may be provided on the purifier shaft bolt 6061 to position the third purifier wheel 6060 away from the mounting strip 6080 and the second purifier wheels 1060-2, 2060-2, 3060-2, 4060-2 outwards. Although...

[0203] It should also be understood that, although Figures 73 to 80 The third ridge clearer wheel 6060 is shown to be mounted adjacent to the second ridge clearer wheels 1060-2, 2060-2, 3060-2, and 4060-2 on the second side. However, the third ridge clearer wheel 6060 may be mounted adjacent to the first ridge clearer wheels 1060-1, 2060-1, 3060-1, and 4060-1 on the first side.

[0205] Figures 81 to 85 Another embodiment of a clearer assembly 7000 is shown, which includes an embodiment of a clearer diverter assembly 7010. Although Figures 81 to 85 The illustration shows a mulcher assembly 7000 utilizing an embodiment of the mulcher assembly 4000; however, it should be understood that any of the other embodiments of the mulcher assemblies 1000, 1000A, 2000, 2000A, 3000, 3000A, 4000A, and 5000 described above can be configured to include the mulcher diverter assembly 7000. Therefore, instead of a separate set of figures for each mulcher assembly embodiment, this illustration is presented. Figures 81 to 85 Includes reference numerals corresponding to each of the clearer assembly frames 1100, 2100, 3100, 4100, and their respective components may be adapted to include the clearer diverter assembly 7010.

[0206] Figure 81 This is a right front perspective view of a clearer assembly 7000, including an embodiment of a clearer diverter assembly 7010. Figure 82 and Figure 83 They are respectively with Figure 81 Top and bottom views of the 7000 purifier assembly. Figure 84 Is it like this? Figure 81 The same view of the clearer assembly 7000 is shown, but the clearer wheel has been removed for better illustration of the embodiment of the clearer diverter assembly 7010. Figure 85 Is with Figure 84Same view, but showing the decomposed clearer diverter assembly 7010. Figure 86 yes Figure 81 Rear perspective view of the clearer diverter assembly.

[0207] Reference Figures 84 to 86 The clearer diverter assembly 7010 includes a vertically oriented diverter plate 7012, which is supported at the front end of the lower sub-frames 1100C, 2100C, 3100C, and 4100C of the clearer frame assemblies 1100, 2100, 3100C, and 4100C of any one of the clearer embodiments 1000, 1000A, 2000, 2000A, 3000, 3000A, 4000, 4000A, and 5000. The diverter plate 7012 is positioned such that it is disposed between the cleaning rollers 1060-1, 1060-2; 2060-1, 2060-2; 3060-1, 3060-2; 4060-1, 4060-2 and extends forward from the cleaning rollers 1060-1, 1060-2; 2060-1, 2060-2; 3060-1, 3060-2; 4060-1, 4060-2 in the direction of travel shown in the figure. It has been found that under certain conditions, the row clearing wheels 1060-1, 1060-2; 2060-1, 2060-2; 3060-1, 3060-2; 4060-1, 4060-2 can pull crop residue in both directions, leaving some residue in the rows or seedbeds. This can cause some crop residue to become trapped in the seed furrows 38 formed by the tail opening assembly 234. Therefore, by positioning the forward-extending diverter plate 7012 between the row clearing wheels, which lifts and disperses the crop residue in front of the row clearing wheels, pressurizing the crop residue to one or both sides, the row clearing wheels can move crop residue more efficiently from the rows or seedbeds, making it less likely that any crop residue will become trapped in the seed furrows 38.

[0208] The leading edge 7014 of the splitter plate 7012 may be angled to form a sharp blade. In other embodiments, the leading edge 7014 may have a flat, rounded, or blunt edge. In some embodiments, the splitter plate 7012 may have a profile such that the upper portion of the leading edge 7014a is convex in the direction of movement 11 and the lower portion 7014b is concave in the direction of movement 11.

[0209] In one embodiment, the splitter plate 7012 is sandwiched between two side plates 7016-1 and 7016-2. For example... Figure 85As best shown, the diverter plate 7012 includes a vertically oriented elongated slot 7018 aligned with an aperture 7020 in the side plates 7016-1, 7016-2. A threaded connector 7022 extends through the aperture 7020 and the elongated slot 7018 and is secured by a nut 7024. The elongated slot 7018 allows the diverter plate 7012 to be vertically adjustable relative to the side plates 7016-1, 7016-2, such that the diverter plate 7012 can be positioned to contact the soil surface or penetrate the soil surface at a desired depth, which may be less than or greater than the seed depth.

[0210] like Figure 84 and Figure 85 As best shown, the purifier diverter assembly 7010 may include an adapter assembly 7030 configured to be mounted with forward-extending purifier wheel support arms 1130-1, 1130-2; 2130-1, 2130-2; 3130-1, 3130-2; 4130-1, 4130-2, including lower subframes 1100C, 2100C, 3100C, 4100C. Figure 85 and Figure 86 As best shown, the adapter assembly 7030 may include a vertically oriented plate 7032 attached to a substrate 7034 (e.g., by welding or other suitable connection means). Rearwardly extending arms 7036-1, 7036-2 may be attached to the substrate 7034 (e.g., by welding or other suitable connection means). The rearwardly extending arms 7036-1, 7036-2 may have apertures 7038 positioned to align with apertures 1135, 2135, 3135, 4135 (or other apertures) in the cleaning wheel support arms 1130-1, 1130-2; 2130-1, 2130-2; 3130-1, 3130-2; 4130-1, 4130-2. If orifice 7038 is positioned aligned with orifices 1135, 2135, 3135, 4135, then the cleaner shaft bolts 1061-1, 1061-2; 2061-1, 2061-2; 3061-1, 3061-2; 4061-1, 4061-2 can be received by aligning orifices 7038 and 1135, 2135, 3135, 4135 to be used in combination with other bolts and nuts (not shown) to secure the adapter assembly 7030 to the cleaner wheel support arms 1130-1, 1130-2; 2130-1, 2130-2; 3130-1, 3130-2; 4130-1, 4130-2. The vertical plate 7032 may include vertically spaced orifices 7040. Figure 85The orifice 7040 is aligned with any of a series of horizontally spaced upper orifices 7042 and horizontally spaced lower orifices 7042 in the side plates 7016-1 and 7016-2. The threaded connector 7044 can extend by aligning the orifices 7040 and 7042 and can be secured by the nut 7046 to secure the side plates 7016-1 and 7016-2 to the vertical plate 7032 of the adapter assembly 7030 and thereby secure the splitter plate 7012 to the vertical plate 7032 of the adapter assembly 7030. It should be understood that a series of orifices 7042 allow the side plates 7016-1, 7016-2 to be adjustable forward and backward positioned relative to the adapter assembly 7030, and thus allow the clearer wheel support arms 1130-1, 1130-2; 2130-1, 2130-2; 3130-1, 3130-2; 4130-1, 4130-2 and clearer wheels 1060-1, 1060-2; 2060-1, 2060-2; 3060-1, 3060-2; 4060-1, 4060-2 to change the distance by which the diverter plate 7012 protrudes forward or backward from the clearer wheels 1060-1, 1060-2; 2060-1, 2060-2; 3060-1, 3060-2; 4060-1, 4060-2.

[0211] Figure 87 This is a front perspective view of an alternative embodiment of a diverter assembly suitable for use with an embodiment of the lower subframe 4100C of the clearer assembly 4000, as shown. Figure 50 and Figure 69 As shown. In this embodiment, the lower subframe 4100C includes a front protrusion 7050 extending forward from the manure cleaner support arms 4130-1, 4130-2. Each of the other embodiments of the manure cleaner assemblies 1000, 1000A, 2000, 2000A, 3000, 3000A, 4000A, and 5000 can be manufactured with a similar front protrusion 7050. For this embodiment, the adapter assembly 7030 can be omitted, and the side plates 7016-1, 7016-2 can be directly mounted to the front protrusion 7050 via a threaded connector 7044, which extends through an opening 7042 in the side plates 7016-1, 7016-2 and through an opening 7052 in the front protrusion 7050 and is secured by a nut 7046. The splitter plate 7012 is attached to the side plates 7016-1 and 7016-2 using a threaded connector 7022, which extends through an opening 7020 in the side plates 7016-1 and 7016-2 and is secured by a nut 7024, the opening 7022 being aligned with an elongated slot 7018 in the splitter plate 7012, as in the previous embodiment.

[0212] Downforce monitoring

[0213] It would be desirable to measure the load experienced by the clearer assemblies 1000, 1000A, 2000, 2000A, 3000, 3000A, 4000, 4000A, 5000, 6000, and 7000 to determine whether a greater or lesser downforce should be applied by the actuator systems 1300, 2300, 3300, 4300, and 5300. Refer to 88 to... Figure 91 The side view shows each of the embodiments 1000, 1000A, 2000, 2000A, 3000, 3000A, 4000, 4000A with the removal of the respective first clearing wheel 1060-1, 2060-2, 3060-1, 4060-1.

[0214] One method for measuring the load experienced by a respective clearer assembly is to utilize a load sensor 8000 disposed on the lower subframes 1100C, 2100C, 3100C, 4100C. In one embodiment, the load sensor 8000 may be a load pin 8002, which replaces the guide wheel shaft bolts 1051, 2051, 3051, 4051 of the respective embodiments of the clearer assemblies 1000, 2000, 3000, 4000, 5000, 6000, 7000. An example of a suitable load pin 8002 is disclosed in U.S. Patent No. 8,561,472.

[0215] In another embodiment, the load sensor 8000 may be a Wheatstone bridge 8004, which is disposed on one or both of the clearer support arms 1130-1, 1130-2; 2130-1, 2130-2; 3130-1, 3130-2; 4130-1, 4130-2 of the respective lower subframes 1100C, 2100C, 3100C, 4100C.

[0216] In yet another embodiment, load sensor 8000 may include load sensor 8010, which is substantially identical to the handle assembly described in PCT Publication No. WO2019169369, designated by reference numeral (i.e., "1600") in that PCT. (Refer to 88 to...) Figure 93 The load sensor 8010 is an assembly including a sleeve 8012 having a handle bracket 8014 at its upper end for pivotally connecting a handle 8016 to a pivot pin 8018. (Refer to 92 to...) Figure 93Depending on the configuration, the side plate 8020 extends between the connecting rods 1200-1, 1200-2; 2200-1, 2200-2; 3200-1, 3200-2; 4200-1, 4200-2 or between the side guide rails 1121-1, 1121-2; 2121-1, 2121-2; 3121-1, 3121-2; 4121-1, 4121-2 of the intermediate subframes 1100B, 2100B, 3100B, 4100B. In some embodiments, the side plate 8020 may be the base members 1120, 2120, 3120, 4120 of the intermediate subframes 1100B, 2100B, 3100B, 4100B. Side plate 8020 includes a hole 8021 through which sleeve 8012 extends. A contact plate 8022 is disposed above side plate 8020, the contact plate 8022 having a convex lower surface 8023 and a central bore 8024 passing through it, such that the convex lower surface 8023 contacts side plate 8020. A load sensing component 8030, such as a "pancake" load sensor, is disposed above contact plate 8022. Figures 95 to 96 The load sensing member 8030 has a hole 8032 passing through it. The load sensing member 8030 includes a plurality of feet 8033 ( Figure 96 It is positioned to allow the load sensing element 8030 to bend and measure force. The bending of the load sensing element 8030 generates a load signal, which is communicated to the monitor 50 or the control module (discussed later).

[0217] like Figure 94 As best shown, the sleeve 8012 has a first diameter 8034 and a larger second diameter 8035, resulting in a shoulder 8036 between them. The first diameter 8034 and the second diameter 8035 pass through a hole 8032 in the load sensing member 8030. The first diameter 8034 is sized to pass through the central bore 8024 of the contact plate 8022, but the second diameter 8035 and the shoulder 8036 are sized such that they cannot pass through the central bore 8024 of the contact plate 8022.

[0218] Refer again Figure 92 and Figure 93Angled washers 8040 and 8042 are disposed on the sleeve 8012 below the handle bracket 8014 and above the load sensing member 8030. The angled washers 8040 and 8042 are configured such that their concave surfaces face each other, allowing them to be elastically compressed or flattened to absorb shocks experienced by the cleaning assemblies 1000, 1000A, 2000, 2000A, 3000, 3000A, 4000, 4000A, 5000, 6000, and 7000, thereby preventing overload of the load sensing member 8030. Before the angled washers 8040 and 8042 are sufficiently compressed due to the load, the shoulder 8036 of the sleeve 8012 contacts the upper surface of the contact plate 8022 to limit the vertical travel of the sleeve 8012. Washer 8045 can be positioned below side plate 8020. At the lower end of sleeve 8012, in bore 8047 ( Figure 94 The shaft 8046 is received internally. A shaft bracket 8048 is mounted to the lower end of the shaft 8046. The shaft bracket 8048 includes an aperture 8049 for receiving the purifier wheel axle bolts 1061-1, 1061-2; 2061-1, 2061-2; 3061-1, 3061-2; 4061-1, 4061-2 or a rod 8050 extending near the axis of the purifier wheel axle bolts 1061-1, 1061-2; 2061-1, 2061-2; 3061-1, 3061-2; 4061-1, 4061-2 between the purifier wheel support arms 1130-1, 1130-2; 2130-1, 2130-2; 3130-1, 3130-2; 4130-1, 4130-2.

[0219] It should be understood that, despite Figures 88 to 92The diagram illustrates all types of load sensors 8000, 8002, 8004, and 8010 on a clearer assembly 1000, 1000A, 2000, 2000A, 3000, 3000A, 4000, and 4000A. This is for illustrative purposes only, to illustrate the placement of load sensors 8000, 8002, 8004, and 8010, as each clearer assembly 1000, 1000A, 2000, 2000A, 3000, 3000A, 4000, 4000A, 5000, 6000, and 7000 will require only one type of load measuring device. Load sensors 8000, 8002, 8004, and 8010 can communicate with monitor 50 to maintain the desired downforce. Load sensors 8000, 8002, 8004, and 8010 can communicate directly with the monitor or via the control module. Alternatively, load sensors 8000, 8002, 8004, and 8010 can be used together with actuator systems 1300, 2300, 3300, 4300, and 5300 as part of a closed-loop or open-loop system to maintain a desired downforce, for example, as disclosed in International Publication No. WO2014018716. In an arrangement utilizing, for example, the control module disclosed in U.S. Patent No. 9,173,339, the control module may be a row-mounted module that controls the downforce of individual clearer assemblies 1000, 1000A, 2000, 2000A, 3000, 3000A, 4000, 4000A, 5000, 6000, and 7000, or the control module may be configured to control the downforce of multiple clearer assemblies 1000, 1000A, 2000, 2000A, 3000, 3000A, 4000, 4000A, 5000, 6000, and 7000 spanning the planter 10. In either case, signals from load sensors 8000, 8002, 8004, and 8010 are communicated to and processed by the control module. In yet another embodiment, the controller may be a single-line or multi-line control module as described in PCT Publication No. WO2014018717, wherein load sensors 8000, 8002, 8004, and 8010 are connected to a CAN network with a CAN processor. In such an embodiment, the CAN processor can communicate with signals from load sensors 8000, 8002, 8004, and 8010 via the CAN network, and the CAN processor can also communicate with control signals via the CAN network to control the downforce of one or more clearer components 1000, 1000A, 2000, 2000A, 3000, 3000A, 4000, 4000A, 5000, 6000, and 7000.

[0220] The above description and figures are intended to be illustrative and not restrictive. Various modifications to the embodiments and general principles and features of the modular metering system and metering modules, as well as the processes described herein, will be apparent to those skilled in the art. Therefore, this disclosure should be given the broadest scope consistent with the appended claims and the full scope of equivalents entitled to such claims.
