[0027] Reference Figures 1 to 4As shown, a ditching device according to an embodiment of this application includes a traction frame 100, a ditching plow 200, and rollers 300. The traction frame 100 extends in a front-to-back direction, and a connector 130 is provided at the front end of the traction frame 100, which can be bolted to the traction device. Optionally, the traction device can be an existing mulching machine traction device (driven by a diesel engine to move the traction wheels), which will not be described in detail here. A mounting beam 110 is provided at the rear end of the traction frame 100. The mounting beam 110 is perpendicular to the traction frame 100, and ridging plates 120 are connected to both ends of the mounting beam 110. The ridging plates 120 at both ends are symmetrically arranged. Optionally, the ridging board 120 is provided with a guide part 123 at the front end. The guide part 123 is a plate that is inclined at the front end in a direction away from the traction frame 100. The guide part 123 can gather and guide the soil to accumulate, thereby improving the ridging efficiency of the ridging board 120. The bottom end of the ridging board 120 is inclined in a direction away from the traction frame 100, so that the ridging board 120 can compact the soil and form a ridge with a trapezoidal cross section.

[0028] The furrowing plow 200 includes a connector 210, a plow head 220, and two furrowing plates 230. The connector 210 can move up and down relative to the traction frame 100 or be fixed to the traction frame 100. The plow head 220 is located between the two ridging plates 120 and at the rear end of the ridging plates 120. The top of the plow head 220 is hinged to the connector 210. A hinge seat 222 is provided on the rear side of the plow head 220. The connector 210 is provided with a first adjusting member 240, which is connected to the hinge seat 222 on the plow head 220 to control the rotation of the plow head 220 relative to the connector 210. Optionally, the first adjusting member 240 can be a crank-connecting rod structure, a locking structure with an arc-shaped slot, etc., which will not be described in detail here.

[0029] Two furrowing plates 230 are symmetrically arranged on both sides of the plowshare 220 and located behind the plowshare 220. Both furrowing plates 230 are hinged to the plowshare 220. A support portion 221 is provided on the side of the plowshare 220 away from the traction frame 100, and the support portion 221 extends in the front-rear direction. The support portion 221 is provided with a second adjusting member 250, which is connected to the furrowing plates 230 to control the rotation of the furrowing plates 230 relative to the plowshare 220. In this embodiment, the second adjusting member 250 is set as a knob, and the outer periphery of the knob is provided with adjusting teeth. The furrowing plates 230 are hinged with adjusting plates 231, and the adjusting plates 231 are provided with strip grooves. The inner wall of the strip grooves is provided with tooth grooves that mesh with the adjusting teeth. The knob passes through the strip grooves of the adjusting plates on both furrowing plates 230, ensuring that the user can drive the two furrowing plates 230 to rotate synchronously when turning the knob.

[0030] The roller 300 is installed at the rear end of the support 221 and located between the two ridging plates 120. The support 221 is provided with a third adjusting member 310, which is connected to the roller 300 to control the up and down movement of the roller 300. Optionally, the third adjusting member 310 can be a telescopic sleeve structure fixed by a pin, or an electric push rod, etc., which will not be described in detail here.

[0031] Understandably, before the ditching equipment is put into operation, a traction device can be connected to the traction frame 100. When the ditching equipment is in operation, the traction device pulls the ditching equipment to move in the planting area. The two ridging plates 120 work together to gather the soil and form ridges. The plow head 220 of the ditching plow 200 simultaneously opens grooves on the ridge surface for transplanting chain-type paper pot seedling trays. The ditching plate 230 expands and compacts the side walls of the grooves, integrating the ridging and ditching functions to achieve simultaneous ridging and ditching.

[0032] By setting the connector 210, the user can adjust the vertical position of the connector 210 to adjust the trench depth. By setting the first adjusting member 240, the user can adjust the angle of the plow head 220 to change the working depth of the plow head 220 into the soil, adapting to soil surfaces with different inclination angles. By setting the second adjusting member 250, the user can adjust the angle of the trenching plate 230 to adjust the trench width. By setting the third adjusting member 310, the user can adjust the vertical position of the roller 300 to ensure that the roller 300 has good grounding, reduce the friction on the trenching equipment, and distribute the pressure of the trenching plow 200, optimize the stress distribution of the trenching force, and improve the smoothness of the trenching force.

[0033] Users can freely adjust the external dimensions of the trenches using the connector 210, the first adjusting member 240, and the second adjusting member 250. The height of the roller 300 can be adjusted using the third adjusting member 310 to accommodate the adjusted plow head 220, allowing the trenching equipment to adapt to different terrains and improving its adaptability. This enables the rapid creation of trenches that meet the transplanting requirements of chain-type paper pot seedling trays of different sizes. By placing the first adjusting member 240 on the connector 210, and the second adjusting member 250, the third adjusting member 310, and the roller 300 on the support 221, the layout of the components in the trenching plow 200 can be optimized, improving the space utilization of the trenching plow 200, reducing its size, and facilitating the transportation and deployment of the trenching equipment.

[0034] Furthermore, the rear end of the ridging board 120 is provided with an extension section 122, which is used to install an extension board. Optionally, the extension section 122 can be a structure such as a mounting hole, hook, or groove opened on the ridging board 120, which will not be described in detail here.

[0035] By setting up the extension section 122, users can install extension plates on tobacco seedlings with special planting requirements to obtain ridge planting that meets the planting requirements, thereby expanding the applicable scope of the ditching equipment and further improving its practicality.

[0036] Reference Figure 1 As shown, it can be understood that lifting components 140 are provided on both opposite sides of the trenching plates 230 at both ends. The lifting components 140 are used to control the raising and lowering of the trenching plates 230. Optionally, the lifting components 140 can be supports, telescopic rods, etc., that are detachably connected to the trenching plates 230, which will not be described in detail here.

[0037] By incorporating the lifting assembly 140, users can adjust the overall height of the trenching plate 230 when using the trenching equipment, thereby controlling the height of the ridges and further improving the controllability of the trenching equipment.

[0038] Furthermore, the lifting assembly 140 includes a base 141, a foot support, and a drive component 142. The base 141 is fixedly connected to the ridging plate 120, the foot support is located below the base 141, and the drive component 142 is mounted on the base 141 and connected to the foot support to drive the foot support to move up and down. Optionally, the drive component 142 may be a crank-screw structure rotatably connected to the base 141, or a telescopic rod structure pinned to the base 141, etc., which will not be described in detail here.

[0039] By setting up the base 141 and the foot support, on the one hand, the foot support can increase the contact area between the lifting component 140 and the ground, thereby improving the stability of the lifting component 140. On the other hand, by using the drive component 142 to lift the foot support, the drive structure of the lifting component 140 can be simplified, making it easier for users to control and adjust, and improving the user experience of the lifting component 140.

[0040] Reference Figure 2 As shown, it can be understood that the first adjusting member 240 includes a first lead screw 241 and a bushing 242. The first lead screw 241 is rotatably connected to the connecting member 210, and the bushing 242 is fixed to the first lead screw 241. The plow head 220 is hinged to the bushing 242 through the hinge seat 222. The third adjusting member 310 includes a second lead screw 311. The second lead screw 311 is rotatably connected to the support part 221, and the roller 300 is disposed at the bottom end of the second lead screw 311.

[0041] Reference Figure 3As shown, in another embodiment of this application, a linkage assembly 320 is provided between the first adjusting member 240 and the third adjusting member 310. The linkage assembly 320 is used to link the first adjusting member 240 and the third adjusting member 310 so that the bottom end of the plowshare 220 and the bottom end of the roller 300 fall on the same horizontal plane. Optionally, the linkage assembly 320 includes a first turbine, a second turbine, and a transmission rod. The first turbine is sleeved on the first lead screw 241, the second turbine is sleeved on the second lead screw 311, and the transmission rod is rotatably mounted on the support part 221 and located above the second adjusting member 250. Both ends of the transmission rod are respectively provided with worm gear portions that mesh with the first turbine and the second turbine. In addition, in some embodiments, the linkage assembly 320 can also be a multi-end synchronous belt structure connected to the ends of the first lead screw 241 and the second lead screw 311, with the tensioning pulley in the middle of the synchronous belt mounted on the support part 221.

[0042] By setting up the linkage component 320, when the user rotates the first lead screw 241 (or the second lead screw 311), the linkage component 320 rotates synchronously and drives the second lead screw 311 (or the first lead screw 241) to rotate synchronously, thereby realizing the linkage between the first adjusting component 240 and the third adjusting component 310. This ensures that when the plow head 220 rotates, the roller 300 can rise and fall synchronously, thus ensuring that the bottom end of the plow head 220 and the bottom end of the roller 300 fall on the same horizontal plane. This simplifies the original two independent adjustment processes into one adjustment process, improving the ease of use of the ditching equipment.

[0043] It should be noted that, since both the first lead screw 241 and the second lead screw 311 move vertically during rotation, the first turbine and the second turbine are both extended vertically to counteract the vertical displacement of the first lead screw 241 and the second lead screw 311.

[0044] Reference Figure 1 and Figure 4 As shown, it can be understood that the traction frame 100 is provided with a first mounting frame 150, which is a rectangular structure formed by bending sheet metal. The first mounting frame 150 is provided with an insertion hole 151 and two first pin holes 152. The two first pin holes 152 are symmetrically connected to both sides of the insertion hole 151. The connector 210 is an L-shaped right-angle plate. The connector 210 is provided with an insertion part 211 (i.e., a plate extending vertically from the right-angle plate). The insertion part 211 is provided with multiple through holes 2111. The multiple through holes 2111 are arranged at intervals along the vertical direction. The first mounting frame 150 is connected with a fixing pin 160. The insertion part 211 is inserted into the insertion hole 151 and the fixing pin 160 passes through the first pin hole 152 and one of the through holes 2111.

[0045] By setting the first mounting bracket 150 and the insertion part 211, the structure of the first mounting bracket 150 and the insertion part 211 is simple and easy to manufacture. It can simplify the connection structure between the connector 210 and the traction frame 100, reduce the manufacturing and installation cost of the connector 210, and the insertion hole 151 of the first mounting bracket 150 can limit the insertion part 211 in the circumferential direction, so that the user can fix the connector 210 with only one fixing pin. At the same time, it is convenient for the user to adjust the height of the connector 210 and ensure the installation stability of the connector 210.

[0046] Furthermore, the mounting beam 110 is connected to a plurality of second mounting brackets 112. The second mounting brackets 112 and the first connector 210 have the same shape and are equal in size. The plurality of second mounting brackets 112 are spaced apart along the direction of the mounting beam 110.

[0047] By setting multiple second connecting frames, the user can install the connector 210 onto any of the second connecting frames to adjust the position of the furrowing plow 200 on the mounting beam 110, thereby adjusting the furrowing position on the ridge surface. The user can also add an additional furrowing plow 200 to the second connecting frame, enabling the furrowing equipment to simultaneously open multiple furrows on the ridge surface.

[0048] Continue to refer to Figure 1 As shown, it can be understood that the mounting beam 110 is provided with a plurality of second pin holes 111, which are arranged at intervals along the direction of the mounting beam 110. The ridge plate 120 is provided with a first connecting sleeve 121, which is fitted onto the mounting beam 110 and connected with a fastener. The fastener is inserted into one of the second pin holes 111.

[0049] By setting the first connecting sleeve 121 and the second pin hole 111, the ridging plate 120 can be installed easily and the user can easily adjust the position of the ridging plate 120 on the crossbeam, thereby facilitating the control of the ridge width and adapting to tobacco seedlings with different planting requirements, further improving the practicality of the ditching equipment.

[0050] Reference Figure 4 As shown, the mounting beam 110 has multiple second pin holes 111, which are spaced apart along the direction of the mounting beam 110. The second mounting bracket 112 has a second connecting sleeve 1121, which is the same shape and size as the first connecting sleeve 121. The second connecting sleeve 1121 is fitted onto the mounting beam 110 and connected with fasteners, including pins and bolts, which will not be described in detail here. The fasteners are inserted into one of the second pin holes 111.

[0051] By setting the second connecting sleeve 1121, and based on the second pin hole 111 set on the mounting beam 110, it is convenient to install the second mounting frame 112 and convenient for the user to adjust the position of the ridging plate 120 on the crossbeam. This facilitates the control of the position and spacing of multiple trenches, further improves the controllability of the trenching equipment, and reduces the production cost of the second mounting frame 112.

[0052] Furthermore, the cross-sectional shape of the mounting beam 110 is polygonal. Optionally, the cross-sectional shape of the mounting beam 110 can be quadrilateral, pentagonal, or hexagonal, etc., which will not be elaborated here. The first connecting sleeve 121 and the second connecting sleeve 1121 are fitted onto the mounting beam 110, that is, the first connecting sleeve 121 and the second connecting sleeve 1121 are polygonal sleeves that match the shape of the mounting beam 110.

[0053] Setting the mounting beam 110 as a polygonal beam makes it easier for users to fit the first connecting sleeve 121 and the second connecting sleeve 1121 together, reduces the installation direction of the first connecting sleeve 121 and the second connecting sleeve 1121, facilitates the alignment of the fasteners with the second pin hole 111, and effectively improves the ease of loading and unloading the ridging plate 120 and the second mounting bracket 112.

[0054] Obviously, the above embodiments of this utility model are merely examples for clearly illustrating the present utility model, and are not intended to limit the implementation of the present utility model. Those skilled in the art can make various obvious changes, readjustments, and substitutions without departing from the protection scope of this utility model. It is neither necessary nor possible to exhaustively describe all embodiments here. Any modifications, equivalent substitutions, and improvements made within the spirit and principles of this utility model should be included within the protection scope of the claims of this utility model.
