Description

Technical Field

[0001] This utility model relates to the field of tillage equipment technology, specifically to a ditching and soil covering device and a four-wheeled riding micro-tiller. Background Technology

[0002] Ditching and covering with soil are two important operations in agricultural production. Ditching helps prevent waterlogging in the field and facilitates fertilization and planting. Covering with soil can effectively cover seeds or seedlings, making the soil temperature and humidity more stable.

[0003] To save labor, the current farming process generally involves first attaching a ditching implement to a mini-tiller, which then moves and drags the implement to create the ditch. Next, a soil-covering implement is used, and soil is covered along the created furrow. However, disassembling and changing different implements is time-consuming and labor-intensive, reducing farming efficiency. Utility Model Content

[0004] In order to overcome the shortcomings of the existing technology, one of the objectives of this utility model is to provide a trenching and covering device that can quickly switch the tillage state.

[0005] The technical solution adopted in this utility model is as follows:

[0006] A ditching and covering device further includes a limiting component and a rotating mechanism. The rotating mechanism can drive the ditching implement and the covering implement to rotate. After rotating to a specified angle, the limiting component limits the rotating mechanism, which can switch to the covering mode or the tillage mode.

[0007] Working principle: When the device is in the soil covering mode or the tillage mode, it can complete the ditching or soil covering work under the drag of the micro tiller. In the tillage process, the ditching tool is used to open the ditch first. After sowing in the ditch, the limiting component is released, and the ditching tool and the soil covering tool are rotated so that the soil covering tool contacts the ground and the ditching tool is removed from the ground. The limiting component is used to fix it again and switch to the soil covering mode to carry out the soil covering work.

[0008] Compared with the prior art, the beneficial effects of this utility model are as follows:

[0009] The ditching implement and the covering implement can be switched without disassembly using the rotating mechanism and the limiting components, saving time and effort and improving farming efficiency.

[0010] In a preferred embodiment of the present invention, the rotating mechanism includes a first plate and a first rod that rotates about the Y-axis. The first plate is connected to the trenching tool, the first rod and the covering tool in sequence along the length direction.

[0011] Beneficial effects: With the above structure, different trenching tools and soil covering tools can be switched every 180 degrees of rotation of the first plate, with the first rod as the rotation center.

[0012] In a preferred embodiment of the present invention, the first plate is provided with a plurality of first through holes in sequence along its length, and the first rod and the trenching tool are respectively bolted to the first rod through the corresponding first through holes.

[0013] Beneficial effects: The installation position of the first rod can be adjusted according to the tillage depth and the height of the implements. By passing through different first through holes, the height of the two implements at both ends of the first plate can be changed to adapt to more tillage environments.

[0014] In a preferred embodiment of this utility model, the rotating mechanism includes a second plate, a first cylinder is fixedly connected to the middle of the second plate along the Y-axis, the end of the first rod away from the first plate is rotatably installed in the first cylinder, and the second plate has two second through holes symmetrically opened about the central rod. The limiting component is inserted into the corresponding second through hole to limit the central rod.

[0015] Beneficial effects: The two symmetrically opened through holes facilitate positioning when the machine is manually switched and rotated 180 degrees each time, ensuring the relative angle between the machine and the ground.

[0016] In a preferred embodiment of this utility model, two third plates are spaced apart at the middle of the first rod. Each of the two third plates has a third through hole corresponding to the second through hole. The limiting component includes an elastic element and a second rod. When the limiting component is in a limiting position, the second rod passes through the third through hole and the corresponding second through hole in sequence. The elastic element is installed on the second rod and is located between the two third plates. When the second rod is disengaged from the second through hole, the elastic element is compressed.

[0017] Working principle: When the second rod is pulled outward, the elastic element is compressed and disengaged from the corresponding second through hole. At this time, rotating the second rod around the first rod can drive the first rod to rotate through the third plate, thereby driving the first plate to rotate. During the rotation, no outward pulling force is applied, and the elastic element has a tendency to recover its deformation. After rotating 180 degrees, the elastic element will automatically drive the second rod to extend into the corresponding second through hole, completing the limit.

[0018] Beneficial effects: The above structure allows for precise positioning of the equipment during switching, and is easy to operate.

[0019] In a preferred embodiment of the present invention, the elastic element includes a compression spring and a pressure ring. The pressure ring is mounted on the second rod and located between the two third plates. The compression spring is sleeved on the second rod and located between the pressure ring and the corresponding third plate.

[0020] Beneficial effects: The pressure ring and compression spring allow the compression spring to be compressed when the second rod is pulled out. When the compression spring returns to its original position, the pressure ring can drive the second rod to move.

[0021] In a preferred embodiment of the present invention, the soil covering tool includes a triangular frame, the straight side of which is connected to a rotating mechanism. When in the soil covering state, the lower part of the two inclined sides of the triangular frame extends downward into the soil, and the upper part of the two inclined sides is integrally formed with a bent part, and the two bent parts are connected.

[0022] Beneficial effect: By setting up a triangular frame with a bend, the triangular frame has better structural strength during cultivation.

[0023] In a preferred embodiment of the present invention, the ditching tool includes a plowshare and two fourth plates. One end of each of the two fourth plates is fixedly connected to the two inner walls of the plowshare, and the other end of each of the two fourth plates is connected to a rotating mechanism.

[0024] Beneficial effects: Due to the structural characteristics of the plowshare, the whole structure is a V-shaped structure with a certain curvature. It is supported obliquely by the two inner walls of the two fourth plates of the plowshare, which makes the force more even and improves the overall structural strength.

[0025] In a preferred embodiment of this utility model, a third rod is provided on the inner side of the plowshare to support it on the ground.

[0026] Beneficial effect: By setting up a third rod, the third rod can be supported on the ground during trenching, making the work more stable.

[0027] The second objective of this utility model is to provide a four-wheeled riding micro-tiller that uses the aforementioned ditching and soil-covering device, making it more convenient to switch between different tillage tools, saving time and effort, and improving tillage efficiency.

[0033] Typical embodiments embodying the features and advantages of this utility model will be specifically described in the following description. It should be understood that this utility model can have various variations in different embodiments, all of which do not depart from the scope of this utility model, and the descriptions and illustrations therein are for illustrative purposes only and not intended to limit this utility model.

[0034] In the description of this application, the terms "first", "second", "side", etc., indicate the orientation or positional relationship based on the orientation or positional relationship shown in the accompanying drawings. They are used only for the convenience of describing this application and simplifying the description, and do not indicate or imply that the structure referred to must have a specific orientation, or be constructed and operated in a specific orientation. Therefore, they should not be construed as limitations on this application.

[0035] See Figure 1 As shown, the trenching and covering device of this embodiment includes a trenching tool 1, a covering tool 2, a limiting component 3, and a rotating mechanism 4. The rotating mechanism 4 can drive the trenching tool 1 and the covering tool 2 to rotate. After rotating to a specified angle, the limiting component 3 limits the rotating mechanism 4, switching to trenching mode or covering mode.

[0036] Among them, see Figure 2 As shown, the rotating mechanism 4 includes a first plate 41, a second plate 42, and a first rod 43. The second plate 42 is fixedly connected to a first cylinder 44 along the Y-axis (the forward direction of the micro-tiller during tillage) at its middle part. One end of the first rod 43 is rotatably installed inside the first cylinder 44, and the other end of the first rod 43 is provided with a connecting part 45. The first plate 41 has a plurality of first through holes 411 sequentially opened along its length. The connecting part 45 is connected to the corresponding first through hole 411 by screws. The installation position of the first rod 43 can be adjusted according to the tillage depth and the height of the implements. By passing through different first through holes 411, the height of the two implements at both ends of the first plate 41 can be changed to adapt to more tillage environments.

[0037] In this embodiment, the soil covering tool 2 is welded to one end of the first plate 41, and the trenching tool 1 is installed on the other end of the first plate 41 by screws. In other embodiments, the soil covering tool 2 can be connected to the corresponding through hole by screws, and the trenching tool 1 can be welded.

[0038] Among them, see Figure 2 As shown, a connecting frame 46 is fixedly connected to the side of the second plate 42 away from the first rod 43. The connecting frame 46 can be connected to the rear end of the micro-tiller by bolts.

[0039] Among them, see Figure 2 As shown, the second plate 42 has two second through holes 421 symmetrically opened about the central rod. The first rod 43 has two third plates 431 spaced apart in the middle. Each of the two third plates 431 has a third through hole corresponding to the second through hole 421. The limiting component 3 includes an elastic element 31 and a second rod 32. When the limiting component 3 is limiting, the second rod 32 passes through the third through hole and the corresponding second through hole 421 in sequence. The elastic element 31 is installed on the second rod 32 and is located between the two third plates 431. When the second rod 32 is disengaged from the second through hole 421, the elastic element 31 is compressed. The two symmetrically opened through holes facilitate positioning when the machine is manually rotated 180 degrees each time, ensuring the relative angle between the machine and the ground.

[0040] Among them, see Figure 2 As shown, the elastic element 31 includes a compression spring 311 and a pressure ring 312. The pressure ring 312 is mounted on the second rod 32 and located between two third plates 431. The compression spring 311 is sleeved on the second rod 32 and located between the pressure ring 312 and the corresponding third plate 431. The second rod 32 is provided with a pin hole between the pressure ring 312 and the adjacent third plate 431. A pin 313 is provided in the pin hole to prevent the pressure ring 312 from moving toward the second plate 42. With the above structure, the position of the machine tool can be accurately positioned when switching, and the operation is convenient.

[0041] In other embodiments, the elastic element 31 may be made of rubber.

[0042] The second rod 32 is an L-shaped rod, and the shorter end of the L-shaped rod can be used as a handle for the convenience of the operator.

[0043] Among them, see Figure 3As shown, the soil covering device 2 includes a triangular frame 21. The straight side of the triangular frame 21 is connected to the rotating mechanism 4. When in the soil covering state, the lower part of the two inclined sides of the triangular frame 21 extends downward into the soil. The upper part of the two inclined sides is integrally formed with a bent part 22, and the two bent parts 22 are connected. By setting the triangular frame 21 with the bent part 22, the triangular frame 21 has better structural strength during cultivation.

[0044] Among them, see Figure 4 As shown, the ditching tool 1 includes a plow head 11 and two fourth plates 12. One end of each of the two fourth plates 12 is fixedly connected to the two inner walls of the plow head 11, and the other end of each of the two fourth plates 12 is connected to the rotating mechanism 4. Due to the structural characteristics of the plow head 11, the whole is a V-shaped structure with a certain curvature. The two fourth plates 12 provide oblique support to the two inner walls of the plow head 11, resulting in more uniform force distribution and improved overall structural strength.

[0045] Among them, see Figure 4 As shown, a third rod 13 is provided on the inner side of the plow head 11 to support the ground; by providing the third rod 13, the third rod 13 can be supported on the ground when digging a trench, making the operation more stable.

[0046] In other embodiments, when both the trenching implement 1 and the covering implement 2 are off the ground, the rotating mechanism 4 is limited, and the device can be switched to walking mode.

[0047] The four-wheeled riding micro-tiller of this embodiment adopts the above-mentioned ditching and soil covering device, which makes it more convenient to switch between different tillage tools, saves time and effort, and improves tillage efficiency.

[0048] The above embodiments are merely preferred embodiments of this utility model and should not be construed as limiting the scope of protection of this utility model. Any non-substantial changes and substitutions made by those skilled in the art based on this utility model shall fall within the scope of protection claimed by this utility model.
