Description

Technical Field

[0001] This application relates to the technical field of agricultural equipment, and in particular to a tracked self-propelled intelligent ditching variable fertilizer applicator. Background Technology

[0002] Currently, most agricultural machinery in the field of agricultural mechanization engineering equipment is integrated. However, hilly and mountainous areas often require going up and down slopes. When existing ditching and fertilizing machines climb slopes, the front ditching and fertilizing components are prone to hitting the ground, hindering the machine's progress and easily damaging them. Although some existing ditching and fertilizing machines can adjust the height of the ditching and fertilizing components, the control structure is complex, resulting in a large overall size of the machine, which is not conducive to climbing slopes.

[0003] Therefore, in the relevant technology, Chinese utility model patent with announcement number CN219165087U provides a tracked remote-controlled hydraulically driven trenching and fertilizing machine for hilly terrain, including a walking component and a trenching and fertilizing component; power is transmitted to the tracked chassis and the trenching and fertilizing component separately through a transfer case, realizing independent control of the two; at the same time, a double-acting cylinder is set, which is connected to the hydraulic oil tank, and can independently control the lifting and lowering of the trenching and fertilizing component; the structure is compact, and the components do not interfere with each other, with strong scalability, which is conducive to subsequent adaptive modification.

[0004] When the walking and ditching components of the trenching and fertilizing machine work simultaneously, the double-acting hydraulic pipe is compressed. The ditching depth can be further adjusted by regulating the extension of the cylinder extension rod. Power from the diesel engine is transmitted in two directions: one path from the transfer case to the gear pump, then to the hydraulic motor, driving the machine; the other path from the transfer case to the left side of the machine, then to the transmission mechanism, which transmits the power through the gearbox to the ditching disc cutter. The machine moves while the ditching disc cutter rotates, completing the ditching operation. A ditching guard prevents soil from flying everywhere after ditching. When the fertilizer hopper discharge plate opens, the ditching and fertilizing operations can be completed in one go, coinciding with the ditching process.

[0005] Regarding the aforementioned related technologies, the inventors believe that: in the related technologies, the small volume of the fertilizer hopper leads to insufficient fertilizer storage, which in turn increases the number of feeding times. At the same time, the feeding method is to manually feed the fertilizer into the hopper. This method of frequent manual feeding not only increases labor intensity but also consumes more time, ultimately affecting the overall efficiency of ditching and fertilization operations. Utility Model Content

[0006] The purpose of this application is to provide a tracked self-propelled intelligent ditching and variable fertilizer applicator to solve the problem in related technologies where the fertilizer hopper has a small volume, resulting in insufficient fertilizer storage and thus increasing the number of feeding operations. In addition, the feeding method is to manually feed the fertilizer into the hopper. This method of frequent manual feeding not only increases labor intensity but also consumes more time, ultimately affecting the overall efficiency of ditching and fertilization operations.

[0007] The technical solution of the tracked self-propelled intelligent trenching and variable fertilizer applicator provided in this application is as follows: A tracked self-propelled intelligent ditching and variable fertilizer applicator includes a tracked walking device and a ditching and fertilizing device and a storage device disposed on the tracked walking device. The storage device includes a storage rack installed on the top of the tracked walking device. The storage rack is provided with a storage hopper. The storage hopper is symmetrically provided with storage chambers. On one side of the storage hopper, there are also symmetrically provided discharge ports that communicate with the two storage chambers. Each of the two storage chambers is provided with a feeding mechanism between it and the two discharge ports. The trenching and fertilizing device includes a bracket mounted on the tracked walking device. A trenching structure is rotatably mounted on one side of the bracket via a swing mechanism. A fertilizer trough is mounted on the trenching structure. A fertilizer hopper is mounted on the inlet of the fertilizer trough via a material guiding mechanism. The fertilizer hopper cooperates with the discharge port. The tracked walking device is also equipped with a hydraulic transmission structure connected to the trenching structure.

[0008] Furthermore, the feeding mechanism includes a spiral conveying rod rotatably disposed between the storage chamber and the discharge port. A feeding drive motor is disposed on the side of the storage hopper away from the discharge port. The output end of the feeding drive motor is connected to one end of the spiral conveying rod, and the feeding drive motor is connected to the hydraulic transmission structure.

[0009] Furthermore, the swing mechanism includes fixed blocks symmetrically arranged on one side of the support, and a hydraulic cylinder is rotatably arranged between the two fixed blocks via a first rotating shaft. The piston rod of the hydraulic cylinder is provided with a U-shaped frame, and a mounting base is provided at the bottom of the grooved structure. A mounting plate is provided on the mounting base via multiple fixing parts, and a connecting block is provided on one side of the mounting plate. The connecting block and the U-shaped frame are hinged together via a second rotating shaft.

[0010] Furthermore, the material guiding mechanism includes a discharge conduit disposed on the inlet of the fertilizer trough, the middle part of the discharge conduit being connected to the inlet of the fertilizer trough, a discharge assembly being disposed inside the discharge conduit, and discharge chambers being symmetrically disposed inside the fertilizer hopper, a connecting plate being disposed between the outlets of the two discharge chambers, and the connecting plate being connected to the top of the discharge conduit by a plurality of locking elements.

[0011] Furthermore, the discharge assembly includes a rotating rod rotatably disposed inside the discharge conduit. The two ends of the rotating rod are respectively provided with a forward spiral blade and a reverse spiral blade. One end of the discharge conduit is provided with a support frame. The support frame is provided with a discharge drive motor. The output end of the discharge drive motor is connected to one end of the rotating rod, and the discharge drive motor is connected to the hydraulic transmission structure.

[0012] Furthermore, each of the two discharge chambers has an adjustment hole at its outlet. An adjustment plate that slidably engages with the inner side of the discharge chamber outlet is slidably disposed in each of the two adjustment holes. A movable handle is provided on one side of each of the two adjustment plates. A top support plate and a bottom support rod are symmetrically disposed in the outlets of the two discharge chambers.

[0014] Furthermore, the top of the storage hopper is symmetrically provided with a cover plate, and both sides of the storage hopper are provided with sight glasses.

[0015] Compared with the prior art, the beneficial effects of this application are as follows: By setting up a device that coordinates the storage rack, storage hopper, storage chamber, discharge port, and feeding mechanism, when the fertilizer hopper is empty, the angle of the fertilizer hopper is adjusted by the swing mechanism, so that the fertilizer hopper swings to the bottom of the discharge port. Then, the feeding mechanism orderly transports the fertilizer stored in the storage hopper to the discharge port. The fertilizer then falls into the fertilizer hopper through the discharge port, thereby achieving automatic feeding. This reduces labor intensity and saves time, thus improving the overall efficiency of trenching and fertilization operations.

[0016] In addition, the feeding mechanism can quantitatively control the amount of fertilizer applied in the fertilizer hopper, thereby ensuring that different amounts of fertilizer can be applied under different fertilization operating conditions. Attached Figure Description

[0028] The following is in conjunction with the appendix Figure 1-10 This application will be described in further detail.

[0029] This application discloses a tracked self-propelled intelligent ditching and variable-rate fertilizer applicator, referring to... Figure 1 and Figure 2 In this embodiment, the tracked self-propelled intelligent ditching and variable displacement fertilizer applicator includes a tracked walking device 1, a ditching and fertilizing device 2, and a material storage device 3. The tracked walking device 1 is hydraulically driven to move stably and flexibly in hilly terrain, and features low torque and high rotational speed, enabling the ditching and fertilizing machine of this application to perform forward, backward, and in-situ turning movements. Specifically, the structure of the tracked walking device 1 is prior art and will not be described in detail here.

[0030] Meanwhile, the trenching and fertilizing device 2 is installed at the rear of the tracked walking device 1 to complete the trenching and fertilizing operations. Specifically, refer to... Figures 3-5 In this embodiment, the trenching and fertilizing device 2 includes a support 21, a swing mechanism 22, a trenching structure 23, a fertilizer trough 24, a fertilizer hopper 25, a material guiding mechanism 26, and a hydraulic transmission structure 27. The support 21 is installed at the rear of the tracked walking device 1. The trenching structure 23 is rotatably mounted on the side of the support 21 away from the tracked walking device 1 via the swing mechanism 22. Under the driving action of the swing mechanism 22, the swing angle of the trenching structure 23 can be adjusted, thereby allowing the trenching structure 23 to control the depth of trenching operations in mountainous areas. Specifically, the trenching structure 23 includes a gearbox 231 rotatably mounted on the support 21 and a disc cutter 232 connected to the output end of the gearbox 231. All components within the trenching structure 23 are existing technologies and will not be described in detail here.

[0031] More specifically, refer to Figure 4 and Figure 5 In this embodiment, the swing mechanism 22 includes a fixed block 221, a hydraulic cylinder 222, a first rotating shaft 223, a U-shaped frame 224, a mounting base 233, a mounting plate 234, a fixing member 235, a connecting block 236, and a second rotating shaft 237. Two fixed blocks 221 are provided, symmetrically mounted on one side of the bracket 21. The end of the hydraulic cylinder 222 is rotatably mounted between the two fixed blocks 221 via the first rotating shaft 223. The U-shaped frame 224 is mounted at the piston rod of the hydraulic cylinder 222; when the hydraulic cylinder 222 is activated, the piston rod drives the U-shaped frame 224 to extend and retract.

[0032] Meanwhile, the mounting base 233 is installed at the bottom of the gearbox 231 inside the trenching structure 23; the mounting plate 234 is installed on the side of the mounting base 233 away from the gearbox 231 by four fasteners 235; the connecting block 236 is installed on the side of the mounting plate 234 away from the mounting base 233, and the connecting block 236 and the U-shaped frame 224 are hinged to each other by the second rotating shaft 237, so that the hydraulic cylinder 222 is connected to the gearbox 231. Under the drive of the piston rod of the hydraulic cylinder 222, the gearbox 231 drives the disc cutter 232 to swing up and down, thereby adjusting the angle of the disc cutter 232 to effectively control the trenching depth.

[0033] Preferably, in this embodiment, the fasteners 235 are all bolts, and four mounting holes are provided on the mounting plate 234 and four threaded holes are provided on the mounting base 233. By passing the bolts through the mounting holes and then screwing them into the threaded holes, the mounting plate 234 can be securely mounted on the mounting base 233.

[0034] In addition, refer to Figure 2 , Figure 4 and Figure 6 In this embodiment, the fertilizer trough 24 is installed on top of the gearbox 231 of the trenching structure 23. The fertilizer trough 24 allows fertilizer to be conveyed into the trench created by the disc cutter 232. The fertilizer hopper 25 is installed at the inlet of the fertilizer trough 24 via a guiding mechanism 26. The fertilizer hopper 25 holds fertilizer, and the guiding mechanism 26 controls the flow of fertilizer from the hopper 25 into the trough 24. This guiding mechanism 26 allows for quantitative control of the amount of fertilizer applied from the hopper 25, ensuring different application rates under different fertilization conditions.

[0035] The hydraulic transmission structure 27 is mounted on the tracked walking device 1. It is connected to the input end of the gearbox 231 of the trenching structure 23, and also to the tracked walking device 1. Power is transmitted via the gearbox 231 to the trenching disc cutter 232 through the hydraulic transmission structure 27, allowing the machine to move while the trenching disc cutter 232 rotates, thus completing the trenching operation. It should be noted that this hydraulic transmission structure 27 is existing technology and will not be elaborated upon further.

[0036] The structure of the material guiding mechanism 26 is described in detail below: Specifically, refer to Figure 6 and Figure 7In this embodiment, the material guiding mechanism 26 includes a discharge conduit 261, a discharge assembly, a discharge chamber 251, a connecting plate 258, and a locking member 259. The discharge conduit 261 is horizontally installed on the inlet of the fertilizer trough 24, and has a top notch on the side facing away from the fertilizer trough 24. A side notch is also provided in the middle of the side of the discharge conduit 261 that connects to the fertilizer trough 24. The top notch, the side notch, and the inlet of the fertilizer trough 24 are interconnected.

[0037] Meanwhile, the discharge assembly is located inside the discharge conduit 261 to facilitate the transport of fertilizer from the fertilizer hopper 25 to the fertilizer trough 24. There are two discharge chambers 251, which are symmetrically installed inside the fertilizer hopper 25. The connecting plate 258 is installed between the outlets of the two discharge chambers 251, and the connecting plate 258 is fixedly connected to the top of the discharge conduit 261 by multiple locking parts 259, so that the connecting plate 258 is fixedly covered on the top notch of the discharge conduit 261. More specifically, these locking parts 259 are bolt and nut mating structures. Through the threaded engagement of the bolt and nut, the connecting plate 258 can be fixedly connected to the discharge conduit 261, thereby realizing the mutual communication between the two discharge chambers 251 and the discharge conduit 261.

[0038] The structure of the discharge assembly is described in detail below: Specifically, refer to Figure 7 In this embodiment, the discharge assembly includes a rotating rod 262, a forward spiral blade 263, a reverse spiral blade 264, a support frame 265, and a discharge drive motor 266. The rotating rod 262 is rotatably mounted at both ends inside the discharge conduit 261; the forward spiral blade 263 and the reverse spiral blade 264 are respectively mounted on the outer sides of both ends of the rotating rod 262, and the spiral directions of the forward spiral blade 263 and the reverse spiral blade 264 are opposite; the support frame 265 is mounted on the outer side of one end of the discharge conduit 261; the discharge drive motor 266 is mounted inside the support frame 265, with its output end connected to one end of the rotating rod 262 and its input end connected to the hydraulic transmission structure 27.

[0039] When fertilization is required, the discharge drive motor 266 is started. The output end of the discharge drive motor 266 drives the rotating rod 262 to rotate. The rotating rod 262 simultaneously drives the forward spiral blade 263 and the reverse spiral blade 264 to rotate. Since the forward spiral blade 263 and the reverse spiral blade 264 rotate in opposite directions, the fertilizer in the discharge chamber 251 can be transported from the discharge guide pipe 261 to the fertilizer trough 24. Finally, under the guidance of the fertilizer trough 24, the fertilizer falls accurately into the trench opened by the disc cutter 232, thus completing the trenching and fertilization process.

[0040] Better, refer to Figure 7 and Figure 8 In this embodiment, adjustment holes 252 are respectively provided at the outlets of the two discharge chambers 251. Adjustment plates 253 are slidably installed in both adjustment holes 252. The adjustment plates 253 cooperate with the inner side of the outlet of the discharge chamber 251 to isolate the discharge chamber 251. Furthermore, a movable handle 254 is installed on one side of each of the two adjustment plates 253 to facilitate the movement of the adjustment plates 253.

[0041] Meanwhile, a top support plate 255 and a bottom support rod 256 are symmetrically installed in the outlets of the two discharge chambers 251. The top support plate 255 and the bottom support rod 256 are combined to form a sliding frame. Specifically, two sliding frames are symmetrically installed at the outlets of the two discharge chambers 251, and the two sliding frames cooperate with the two sides of the adjusting plate 253. By setting the two sliding frames, the sliding of the adjusting plate 253 can be effectively supported and guided.

[0042] In addition, the amount of fertilizer delivered can be controlled by manually controlling the movement of the adjusting plate 253; and in other embodiments, the movement of the two adjusting plates 253 can be automatically driven by the combination of a motor and a positive and negative threaded rod, thereby achieving an automated control effect.

[0043] Secondly, refer to Figure 2 , Figure 9 and Figure 10 In this embodiment, the storage device 3 is installed on the top of the tracked walking device 1, and the storage device 3 cooperates with the fertilizer hopper 25. When the fertilizer hopper 25 is empty, the storage device 3 can automatically feed the fertilizer hopper 25.

[0044] Specifically, in this embodiment, the storage device 3 includes a storage rack 31, a storage hopper 32, a storage cavity 33, a discharge port 34, and a feeding mechanism. The storage rack 31 is mounted on top of the tracked walking device 1; the storage hopper 32 is mounted on the storage rack 31; two storage cavities 33 are provided, symmetrically installed inside the storage hopper 32, and both storage cavities 33 store fertilizer. Simultaneously, cover plates 35 are symmetrically installed on the top of the storage hopper 32 to seal it; and sight glasses 36 are installed on both sides of the storage hopper 32. The sight glasses 36 allow operators to clearly see the amount of fertilizer in the storage cavities 33, enabling timely replenishment.

[0045] In addition, there are two discharge ports 34. The two discharge ports 34 are symmetrically installed on the side of the storage hopper 32 near the fertilizer hopper 25. The two discharge ports 34 are connected to the two storage chambers 33 respectively. At the same time, the discharge ends of the two discharge ports 34 are both set downward. The two discharge ports 34 cooperate with the two discharge chambers 251 in the fertilizer hopper 25. Under the driving action of the hydraulic cylinder 222, the fertilizer hopper 25 swings to the bottom of the discharge ports 34, so that the two discharge ports 34 correspond to the two discharge chambers 251.

[0046] There are two feeding mechanisms, which are respectively located between the two storage chambers 33 and the two discharge ports 34, so as to orderly transport the fertilizer in the two storage chambers 33 to the two discharge ports 34, and then the fertilizer is discharged from the discharge end of the two discharge ports 34.

[0047] Specifically, refer to Figure 9 and Figure 10 In this embodiment, the feeding mechanism includes a screw conveyor 37 and a feeding drive motor 38. The screw conveyor 37 is rotatably mounted between the storage chamber 33 and the discharge port 34. The feeding drive motor 38 is mounted on the side of the storage hopper 32 away from the discharge port 34. The output end of the feeding drive motor 38 is connected to one end of the screw conveyor 37, and the input end of the feeding drive motor 38 is connected to the hydraulic transmission structure 27.

[0048] When the fertilizer hopper 25 is empty and needs to be filled, the position of the fertilizer hopper 25 is first swung to below the discharge port 34 by the hydraulic cylinder 222. Then, the feeding drive motor 38 is started. The output end of the feeding drive motor 38 drives the screw conveyor 37 to rotate. The rotating screw conveyor 37 conveys the fertilizer in the storage chamber 33 to the discharge port 34. Finally, the fertilizer is discharged from the discharge end of the discharge port 34 into the discharge chamber 251 of the fertilizer hopper 25. This achieves the effect of automatic feeding, thereby reducing labor intensity and saving time, and improving the overall efficiency of trenching and fertilization operations.

[0049] In addition, refer to Figure 3 and Figure 4 In this embodiment, a top frame 257 is also installed on the top of the fertilizer hopper 25. The top frame 257 cooperates with the two discharge ports 34. The top frame 257 can provide some shielding for the top of the fertilizer hopper 25. On the other hand, when the fertilizer hopper 25 swings to below the discharge ports 34, the top frame 257 can effectively guide the fertilizer discharged from the discharge ports 34, so that the fertilizer can be transported into the fertilizer hopper 25 in an orderly manner.

[0050] Preferably, a level sensor is also installed in each of the two storage chambers 33. The level sensor can monitor the changes in the material level in the storage chamber 33 in real time, and the level sensor is connected to the hydraulic cylinder 222. When the level sensor detects that the fertilizer level in the storage chamber 33 is less than the set height, the fertilizer hopper is swung and moved below the discharge port 34 under the drive of the hydraulic cylinder 222. Then, the fertilizer in the storage chamber 33 is transported to the discharge port 34 through the feeding mechanism. Finally, the fertilizer is discharged from the discharge end of the discharge port 34 into the discharge chamber 251 of the fertilizer hopper 25, thereby completing the automatic replenishment process of the fertilizer hopper 25.

[0051] In this embodiment, a speed sensor is also installed in the tracked walking device 1. The speed sensor is connected to the discharge drive motor 266. By setting the speed sensor to sense the rotation of the gears in the tracked walking device 1, the walking speed of the fertilizer applicator is measured. This is then used to control the driving speed of the discharge drive motor 266, so that different fertilizer amounts can be matched at different walking speeds. This allows the fertilizer amount to be determined according to the user's own needs, thereby achieving the effect of variable fertilization.

[0052] Meanwhile, an angle sensor is also installed inside the trenching and fertilizing device 2. This angle sensor is connected to the hydraulic cylinder 222. By setting this angle sensor to measure the swing angle of the trenching structure 23, the trenching depth of the disc cutter 232 is determined. It should be noted that the material level sensor, speed sensor, and angle sensor are all existing technologies and will not be elaborated upon here.

[0053] The above description is merely an embodiment of this utility model and does not limit the patent scope of this utility model. Any equivalent structural or procedural transformations made based on the description and drawings of this utility model, or direct or indirect applications in other related technical fields, are similarly included within the patent protection scope of this utility model.
