[0002] Traditional trenching operations are carried out manually, with low trenching efficiency and difficult to guarantee the forming quality of the trench. With the continuous popularization of agricultural mechanization, currently, vertical spiral trenchers are connected to agricultural tractors through a three-point suspension device to carry out trenching operations. However, most vertical spiral trenchers are only suitable for digging medium-sized trenches, cannot adjust the trenching position, and do not meet the agronomic requirements.

[0004] Some vertical spiral trenchers can change the trenching position. For example, in Chinese patent document CN114753424A, a rotatable mounting adjustment bracket is used in cooperation with the main support frame, and with the assistance of a reversing transmission box one, a power extension sleeve, and a reversing transmission box two, the trenching angle can be adjusted according to the usage needs, so that the trench can be dug in an inverted manner. However, it is not convenient to adjust the position of the soil spreading cover, still requires a lot of time for adjustment and has low adjustment accuracy, affecting the soil spreading effect and trenching efficiency.

The semi-circular traction frame 110 includes a semi-circular support plate 111 and a traction frame 112 vertically arranged upward at the diameter end of the semi-circular support plate 111. The semi-circular traction frame 110 is an overall frame structure with an L-shaped cross-section.

[0037] A plurality of first pin shaft assembly holes are provided on the semi-circular support plate 111. The first pin shaft assembly holes include first assembly holes 113 arrayed along the arc edge and multiple groups of second assembly holes 114 arranged at the lower part of the fan-shaped hollow, which are used to adaptively select appropriate assembly holes to fix the support seat when adjusting the fixed position of the support seat. A bevel gearbox is assembled at the center position of the semi-circular support plate 111 for power output.

[0038] The semi-circular support plate 111 is a plate body composed of a semi-circular support plate and a rectangular support plate horizontally extending along the diameter direction. The first assembly holes 113 are circularly arrayed and extend to both ends of the rectangular support plate; the semi-circular support plate and the rectangular support plate are integrally formed structures; two fan-shaped hollows are also provided symmetrically along the midline at the upper part of the semi-circular support plate for avoiding other components.

[0039] The traction frame 112 is a plate body with a semi-circular notch in the middle. An assembly ear 115 for connecting the three-point suspension device is provided on the back of the traction frame 112, and this semi-circular notch is used to arrange the power input shaft of the gearbox.

[0040] An arc-shaped support bar 116 matching the shape of the semi-circular support plate 111 is also provided at the edge of the semi-circular support plate 111, which is used to strengthen the stability of the semi-circular traction frame 110. The two ends of the arc-shaped support bar 116 are fixedly connected to the traction frame 112, and the bottom surface is fixedly connected to the semi-circular support plate 111.

[0041] Please refer to Figure 3 and Figure 4 , the guiding mechanism 120 is used to adjust the relative positions of the soil scattering cover 140, the cutter assembly 150 below the soil scattering cover 140, and the diversion and shaping assembly 160 on the side of the soil scattering cover 140, so as to be able to adaptively select an appropriate trenching position. Hereinafter, the soil scattering cover 140, the cutter assembly 150 below the soil scattering cover 140, and the diversion and shaping assembly 160 on the side of the soil scattering cover 140 are collectively referred to as the trenching device.

[0042] Specifically, please refer to Figure 6 and Figure 7 the guiding mechanisms in two different states shown in. Both ends of the two groups of guiding mechanisms 120 are respectively hinged to the semi-circular support plate 111 and the soil-dispersing cover 140, and the guiding mechanism 120 can rotate. The four hinge points form a parallelogram, that is, the distances between the two hinge points above the soil-dispersing cover 140 and the distances between the two hinge points on the semi-circular support plate 111 are the same, and the projection of the hinge point on the first hinge seat and the central axis of the bevel gear box are on the same horizontal line, and the projection of the hinge point on the second hinge seat and the tool axis are on the same horizontal line. During the change of the parallelogram, the position of the ditching device is adaptively adjusted, so as to change the ditching position, realize the parallel guiding movement of the ditching device, and use split pins to lock the support seat 125 to ensure the stability and safety of the connection.

[0043] More specifically, a single group of guiding mechanism 120 includes: a connecting rod 121, a first hinge seat 122 and a second hinge seat 123 hinged at both ends of the connecting rod 121. The two connecting rods 121 are symmetrically arranged on the left and right sides of the flange plate assembly. The two ends of the connecting rod 121 are hinge parts, and a support seat 125 that can slide on the connecting rod 121 is arranged on the connecting rod 121; the first hinge seat 122 is fixedly arranged under the semi-circular support plate 111, and the lower part of the first hinge seat 122 is hinged to the hinge part at the end of the connecting rod 121; the second hinge seat 123 is arranged above the soil-dispersing cover 140, and the upper part of the second hinge seat 123 is hinged to the hinge part at the end of the connecting rod 121.

[0044] The hinge seats are made of metal or alloy frames with a C-shaped cross-section and are welded to the semi-circular support plate 111 and the soil-dispersing cover 140 respectively. In other embodiments, the connecting rod 121 can also be directly hinged to the semi-circular support plate 111 and the soil-dispersing cover 140 respectively, or welded with hinge seats of other more stable structures or materials.

[0045] The connecting rod 121 is a flat strip-shaped rod. Hinge holes 124 are arranged at both ends of the connecting rod 121, and the connecting rod 121 and the hinge seat are hinged by a pin shaft. The lengths of the two connecting rods 121 are the same. The support seat 125 includes a sliding sleeve 1251, a support column 1252 and a connecting piece 1253. The sliding sleeve 1251 is sleeved on the connecting rod 121 and can slide on the connecting rod 121. The support column 1252 is used to support the connecting piece 1253 and attach the connecting piece 1253 to the bottom of the semi-circular support plate 111. A second pin shaft assembly hole 1254 for connecting the pin shaft is arranged on the semi-circular support plate 111.

[0046] When it is necessary to adjust the ditching position, only the fixing parts of the two support seats 125 need to be loosened, and the adjusting rod is moved. The chain drive box is driven to rotate by the rotation of the adjusting rod on the semi-circular arc. For the enabling method of the adjusting rod, please refer to the Chinese patent document CN110344463B, so as to adjust the ditching position of the tool and drive the soil scattering cover to perform horizontal guidance. The adjustment method is very convenient; then, fixing parts such as pins or bolts are used to fix the support seat 125 and the semi-circular support plate 111, and the inclination angle of the parallelogram is fixed, so that the position of the ditching device is fixed. A plurality of first pin assembly holes are provided on the semi-circular support plate 111 to improve the adjustment accuracy; and the ditching device is always kept perpendicular to the driving direction of the ditching machine for soil discharge.

[0047] The soil scattering cover 140 is a frame body with an open lower end and two symmetric side edges, that is, the soil scattering cover 140 includes an upper top cover 141, a front soil retaining plate 142 and a rear soil retaining plate 143. The upper top cover 141 is a rectangular plate body, and first ear plates 144 are provided at both ends of the front soil retaining plate 142 and the rear soil retaining plate 143. The guiding mechanism 120 is fixedly connected to the upper surface of the upper top cover 141. A flange plate assembly 145 is provided in the middle of the upper top cover 141 for assembling the tool assembly 150. The transmission mechanism 130 is connected to the bevel gear box and the flange plate assembly 145 to transmit power to the tool assembly 150 installed below the flange plate assembly 145; a diversion and shaping assembly 160 is also assembled on the rear soil retaining plate 143 of the soil scattering cover 140 along the direction of the tool assembly 150.

[0048] The soil scattering cover 140 further includes one or two side end covers 146 for improving the soil regularization effect. The figure shows the case of one side end cover 146. The side end cover 146 is detachably connected to the first ear plates 144 provided at the same-side ends of the front soil retaining plate 142 and the rear soil retaining plate 143. The side end cover 146 is connected to the front soil retaining plate 142 and the rear soil retaining plate 143 by bolt connection, which is convenient for the installation and disassembly of the side end cover 146. When in use, it can be selected to use the side end cover 146 on one end of the soil scattering cover 140, or not use the side end cover 146 at both ends, or even use the side end cover 146 at both ends, achieving the purpose of controllable unidirectional and bidirectional soil discharge of the soil scattering cover 140 during the operation of the ditching machine.

[0049] The side end cover of the soil scattering cover is set to be detachable, realizing controllable unidirectional and bidirectional soil discharge, ensuring uniform soil scattering, being beneficial to shaping, and preventing the soil from scattering in different directions due to the rotation of the soil scattering cover shell and the shaping structure driven by the vertical spiral tool during the adjustment of the ditching position along the circular frame of the ditching machine, which brings interference to the ditching work and meets the different requirements of farmland ditching and orchard ditching.

[0050] Please refer to Figure 5, the flange assembly 145 includes a special-shaped flange 1451 and a tool shaft flange 1452, which are used to assemble the tool assembly 150 and the transmission mechanism 130 to prevent the soil scattering cover 140 from being affected by the transmission mechanism 130. Among them, the special-shaped flange 1451 is composed of a circular flange and a rectangular extension plate extending towards the direction of the flow guiding and shaping assembly 160, and the connection between the circular flange and the rectangular extension plate is smoothly transitioned. The circular flange is installed at the assembly position of the tool assembly 150 on the soil scattering cover 140, and the rectangular extension plate extends outside the rear soil retaining plate 143; the tool shaft flange 1452 is assembled in the middle of the circular flange, and two deep groove ball bearings 1453 are assembled on the tool shaft of the tool assembly 150, and the deep groove ball bearings 1453 are assembled at the center of the tool shaft flange 1452, without affecting the power output.

[0051] In this embodiment, two deep groove ball bearings 1453 are installed on the vertical spiral tool shaft and are embedded in the tool shaft flange 1452. Then, the tool shaft flange 1452 is bolted to the soil scattering cover. The soil scattering cover is not directly connected to the tool shaft of the ditch opener. Therefore, when the ditch opener adjusts the ditch opening position, the soil scattering cover will not move along the arc of the circular frame of the ditch opener together.

[0052] For the purpose of realizing the parallel guiding movement of the side-end detachable soil scattering cover 140 and the flow guiding and shaping mechanism, two deep groove ball bearings 1453 are installed on the vertical spiral tool shaft and are embedded in the tool shaft flange 1452. Then, the output flange is bolted to the soil scattering cover 140. The soil scattering cover 140 is not directly connected to the tool of the ditch opener. Therefore, when the ditch opener adjusts the ditch opening position, it will not move along the arc of the circular frame of the ditch opener together. It is guided and adjusted by the parallel guiding mechanism 120 to keep the position of the soil scattering cover 140 shell and the shaping structure perpendicular to the driving direction of the ditch opener for soil discharging.

[0053] The flow guiding and shaping assembly 160 includes a shaping plate 161 and a flow guiding plate 162. The shaping plate 161 is a trapezoidal plate vertically arranged at the lower part of the rear soil retaining plate 143, and the lower bottom of the shaping plate 161 is fixedly connected to the rear soil retaining plate 143; two flow guiding plates 162 are respectively arranged on both sides of the shaping plate 161, and the included angle between the flow guiding plate 162 and the shaping plate 161 is an obtuse angle.

[0054] The diversion and shaping assembly 160 further includes a connecting pipe 163 and connecting pipe lugs 164, which are used to enhance the structural strength of the shaping plate 161, prevent the shaping plate 161 from deforming, and thus extend the service life of the diversion and shaping assembly 160. Specifically, the connecting pipe 163 is a rectangular square pipe. The upper part of the connecting pipe 163 is welded to the end of the rectangular extension plate of the special-shaped flange 1451. The connecting pipe 163 is fixedly arranged on the central axis of the shaping plate 161, and the lower part of the connecting pipe 163 does not exceed the shaping plate 161. The connecting pipe lugs 164 are welded on both sides of the connecting pipe 163, and the connecting pipe lugs 164 are fixedly connected to the rear retaining plate 143.

[0055] Structures such as the conveyor belt, the driving pulley, and the driven pulley provided in the transmission housing 131 are not improved and will not be elaborated here.

[0056] In summary, the horizontal guiding type soil spreading and shaping device of the vertical spiral trencher provided in this embodiment has a simple structure and is convenient for maintenance, and can solve the problems that the existing vertical spiral trencher cannot adjust the trenching position, the soil spreading cover 140 does not discharge soil perpendicular to the driving direction of the trencher, the opening direction of the soil spreading cover 140 cannot be adjusted during soil discharging, and the adjustment accuracy is not high when operating in farmland / orchards, etc.
