Description

Technical Field

[0001] This invention relates to the field of agricultural machinery technology, and in particular to a high-efficiency plow head for a multi-angle adjustable tiller. Background Technology

[0002] In agricultural production, with the development of intelligent agricultural power machinery and other mechanized agricultural and horticultural machinery manufacturing technologies, the practice of returning straw to the field and retaining a certain amount of weeds to maintain the ecosystem in order to improve soil fertility and reduce environmental pollution is becoming increasingly common. However, when cultivating fields with a large amount of straw returned to the field or with many weed roots, straw, weeds, and roots easily become entangled and accumulate in key areas between the plowshare and the plow frame, causing blockages. Blockages between the plowshare and the plow frame severely reduce cultivation efficiency, forcing the operator to frequently stop to clear the blockages, greatly affecting the cultivation progress. Furthermore, blockages can lead to uneven force on the implements, potentially damaging them over time and increasing maintenance costs. In addition, existing plow designs have limitations; the row spacing between plowshares is not adjustable, making it difficult to flexibly adjust according to the actual situation of straw and weed roots in different plots and the width of the land. This seriously affects cultivation quality and efficiency and is difficult to meet the current demands for flexibility and efficiency in the field of intelligent agricultural power machinery and other mechanized agricultural and horticultural machinery manufacturing. Summary of the Invention

[0003] One objective of this invention is to make the row spacing between plow blades adjustable.

[0004] Another objective of this invention is to reduce the risk of blockage between the plowshare and the plow frame.

[0005] Specifically, this invention provides a multi-angle adjustable high-efficiency ploughing head, comprising: a U-shaped frame, two plow frames, and a first telescopic cylinder; the U-shaped frame is horizontally arranged, with a cover plate and a base plate respectively provided on its upper and lower sides; both ends of the U-shaped frame extend beyond the base plate, and each end of the U-shaped frame is provided with a vertically downward first connecting column; the two plow frames are horizontally arranged below the base plate and are respectively connected to the two first connecting columns; a first sliding groove is provided on the top of the plow frame along its length, and the first connecting column is rotatably slidably arranged in the first sliding groove; a plurality of rotatable plow blades are evenly arranged on the bottom of the plow frame; the first... A telescopic cylinder is positioned above the U-shaped frame and connected to a push plate. Two vertically downward-pointing second connecting columns are respectively installed at both ends of the push plate. These two second connecting columns pass through a cover plate and a bottom plate and are rotatably connected to one end of each of the two plow frames. Both the cover plate and the bottom plate have elongated holes for accommodating the movement of the second connecting columns. When the first telescopic cylinder moves the push plate, it causes the second connecting columns to slide along the elongated holes, thereby moving and deflecting the plow frame, changing the row spacing between adjacent plow blades. The plow blades are configured to rotate in the opposite direction to the plow frame during deflection, thereby reducing the angle between the plow blades and the direction of travel.

[0006] Furthermore, a first gear is fixed on each second connecting post, the first gear being located between the base plate and the cover plate; a first rack is also provided between the base plate and the cover plate, the first rack being located between and meshing with the two first gears; a second gear is fixed at the bottom end of each second connecting post, and two opposing second racks are provided on each plow frame; the second gear extends between and meshes with the two second racks; a third gear is fixed at the top of each plow blade, the third gear extending between and meshing with the two second racks; a second telescopic cylinder is connected to the first rack; the second telescopic cylinder is configured to remain stationary when the first telescopic cylinder moves.

[0007] Furthermore, the second telescopic cylinder is also configured such that, after the first telescopic cylinder stops moving, when the plow blade is deviated from the direction of travel, it pulls the first rack to move, driving the first gear to rotate; the first gear drives the plow blade to rotate through the second connecting column, the second gear, the second rack, and the third gear, thereby reducing the degree of deviation between the plow blade and the direction of travel.

[0008] Furthermore, a second slide groove is provided on the first rack, and a first slider is connected below the push plate, the first slider being slidably disposed in the second slide groove.

[0009] Furthermore, the plow blade includes a plow column that can rotate relative to the plow frame and a plow blade disposed below the plow column. The plow column is provided with vertical blades that can move up and down for cutting the entangled material wrapped around the plow column; wherein the blades have serrated edges.

[0010] Furthermore, each plow frame has multiple sleeves fixedly installed at its bottom end. These sleeves are fitted onto the outside of multiple plow columns in a corresponding manner, and each sleeve has a vertical through groove. The plow column has a wavy third sliding groove along its circumference, and a sliding second slider is installed in the third sliding groove. The second slider passes through the through groove and connects to the blade.

[0011] Furthermore, the plow column is provided with two third sliding grooves, and the two third sliding grooves are symmetrically arranged about the cross-section of the plow column; each third sliding groove is provided with a second slider, and the two second sliders pass through the through groove and are connected to the two blades, so that the two blades move synchronously in opposite directions.

[0012] Furthermore, the two blades located on the same plowshare always partially overlap.

[0013] Furthermore, the plowshare is configured to rotate in both directions as the blades cut the tangled material.

[0014] Furthermore, the multi-angle adjustable high-efficiency ploughing head also includes a connecting frame, which is set on the U-shaped frame and the cover plate for connecting the ploughing machine.

[0015] The beneficial effects of this invention are: The multi-angle adjustable high-efficiency plow head of this invention features a plow frame rotatably and slidably mounted at the bottom of a first connecting column, with one end of the plow frame rotatably connected to a second connecting column. This allows the plow frame to sway under the influence of the second connecting column as the pusher plate moves along with the first telescopic cylinder, thus altering the row spacing between adjacent plow blades. The row spacing can be adjusted according to actual land conditions (soil texture, land width, etc.), broadening its applicability and practicality while improving work efficiency and effectiveness. Furthermore, by having the plow blades rotate in the opposite direction to the plow frame during swaying, the angle between the plow blades and the direction of travel is reduced, decreasing resistance during plowing and further improving work efficiency.

[0016] Furthermore, the multi-angle adjustable high-efficiency ploughing head of the present invention, by setting serrated blades on the plough column, uses the up and down movement of the blades to cut the entangled material wrapped around the plough column, causing the entangled material to break and detach from the plough blades, thereby reducing the risk of blockage between the plough column and the plough frame, and thus ensuring the working efficiency when the plough blades continue to work, and improving the ploughing effect.

[0017] Furthermore, the multi-angle adjustable high-efficiency ploughing head of the present invention is equipped with a plow column that rotates in both directions, so that while the blades move up and down, the plow blades swing back and forth. On the one hand, this can break free from and throw off the tangled material wrapped around it, and on the other hand, it can work with the moving blades to make the blades cut the tangled material more effectively.

[0023] The following reference Figures 1 to 12 This invention describes a multi-angle adjustable, high-efficiency ploughing head provided by the present invention.

[0024] This embodiment provides a multi-angle adjustable high-efficiency tiller head. The multi-angle adjustable high-efficiency tiller head generally includes: a U-shaped frame 100, two tiller frames 200, and a first telescopic cylinder 400.

[0025] A U-shaped frame 100 is horizontally positioned, with a cover plate 110 and a base plate 120 on its upper and lower sides, respectively. Both ends of the U-shaped frame 100 extend beyond the base plate 120, and each end of the U-shaped frame 100 has a vertically downward-pointing first connecting post 130. Two plow frames 200 are horizontally positioned below the base plate 120 and connected to the two first connecting posts 130. A first sliding groove 210 is provided along the length of the top of the plow frame 200, and the first connecting posts 130 are rotatably slidably positioned within the first sliding groove 210. Multiple rotatable plow blades 300 are evenly distributed at the bottom of the plow frame 200. A first telescopic cylinder 400 is positioned above the U-shaped frame 100 and connected to a push plate 410. Each end of the push plate 410 has a vertically downward-pointing second connecting post 420, which passes through the cover plate 110 and the base plate 120 and is rotatably connected to one end of each of the two plow frames 200. Both the cover plate 110 and the base plate 120 are provided with elongated holes 121 for accommodating the movement of the second connecting post 420. When the first telescopic cylinder 400 moves the push plate 410, it causes the second connecting post 420 to slide along the elongated holes 121, thereby moving and deflecting the plow frame 200, changing the row spacing between two adjacent plow blades 300. The plow blades 300 are configured to rotate in the opposite direction to the plow frame 200 during the deflection process, in order to reduce the angle between the plow blades 300 and the direction of travel.

[0026] In this embodiment, the plow frame 200 is rotatably and slidably mounted at the bottom of the first connecting column 130, and one end of the plow frame 200 is rotatably connected to the second connecting column 420. This allows the plow frame 200 to sway under the pull of the second connecting column 420 when the push plate 410 is driven by the first telescopic cylinder 400, thereby changing the row spacing formed by adjacent plow blades 300 during tillage. The row spacing of the plow blades 300 can be adjusted according to the actual land conditions (soil texture, land width, etc.), resulting in a wider range of applications, greater practicality, and improved work efficiency and effectiveness.

[0027] Furthermore, in this embodiment, the plow blade 300 is configured to rotate in the opposite direction to the plow frame 200 during the deflection process of the plow frame 200, thereby reducing the angle between the plow blade 300 and the direction of travel, thus reducing the resistance of the plow blade 300 when plowing and improving the work efficiency.

[0028] like Figure 2 , 3As shown, in some preferred embodiments, the bottom end of the first connecting column 130 is an annular shape that protrudes radially outward, and the first sliding groove 210 on the top of the plow frame 200 is a T-shaped groove that is adapted to the first connecting column 130. This not only ensures that the first connecting column 130 rotates and slides smoothly relative to the plow frame 200, but also restricts the degree of freedom of the plow frame 200 in the vertical direction, thereby improving structural stability.

[0029] like Figure 5 As shown, the two second connecting columns 420 and the two plow frames 200 are symmetrically arranged about the vertical central axis of the U-shaped frame 100. The push plate 410 moves back and forth along the direction of travel directly above the central axis of the U-shaped frame 100. When the push plate 410 drives the second connecting columns 420 to move, the deflection angle of the two plow frames 200 remains consistent, thereby ensuring that the row spacing formed by the multiple plow blades 300 on the two plow frames 200 is uniform and consistent, improving the working effect.

[0030] like Figure 5 , 8 As shown, the plow frame 200 may include two symmetrically arranged side plates 201 and baffles 202 located at both ends of the side plates 201. The side plates 201 and baffles 202 are fixedly connected by screws. The two side plates 201 are joined together to form a first sliding groove 210, an installation space 203 for accommodating the second rack 220, and a moving groove (not shown in the figure) for the plow blade 300 to be installed and moved. The length of the installation space 203 is greater than the length of the rack, so that the rack can move smoothly in the installation space 203.

[0031] To ensure that the plow blade 300 rotates in the opposite direction to the plow frame 200 during its deflection, in some embodiments, a first gear 421 is fixed to each second connecting post 420, located between the base plate 120 and the cover plate 110. A first rack 510 is also provided between the base plate 120 and the cover plate 110, located between and meshing with the two first gears 421. A second gear 422 is fixed to the bottom end of each second connecting post 420, and two opposing second racks 220 are provided on each plow frame 200. The second gear 422 extends between and meshes with the two second racks 220. A third gear 230 is fixed to the top of each plow blade 300, extending between and meshing with the two second racks 220. The first rack 510 is connected to a second telescopic cylinder 500. The second telescopic cylinder 500 is configured to remain stationary while the first telescopic cylinder 400 moves.

[0032] like Figure 3 , 7As shown, when the first telescopic cylinder 400 moves the push plate 410, the push plate 410 drives the second connecting column 420 to move. Since the first gear 421 and the first rack 510 on the second connecting column 420 are in a meshing state, the second connecting column 420 rotates simultaneously during its movement. The rotation of the second connecting column 420 drives the second gear 422 on it to rotate, and the rotation of the second gear 422 drives the two second racks 220 meshing with it to move synchronously in the opposite direction, thereby causing the third gear 230 meshing between the two second racks 220 to rotate. The rotation of the third gear 230 drives the plow blade 300 fixedly connected to it to rotate, reducing the degree of deviation between the plow blade 300 and the direction of travel.

[0033] In this embodiment, by setting a first rack 510, a second gear 422, a second rack 220, and a third gear 230, the plow blade 300 rotates synchronously in the opposite direction during the deflection of the plow frame 200, thereby reducing the degree of deviation between the plow blade 300 and the direction of travel, and thus improving the working efficiency and effect of the plow blade 300.

[0034] In other embodiments, a motor can be installed on the top of each plow blade 300, and by controlling the start and stop of the motor, the plow blade 300 can rotate in the opposite direction during the deflection of the plow frame 200.

[0035] The second telescopic cylinder 500 is also configured such that, after the first telescopic cylinder 400 stops moving, when the plow blade 300 is deviated from the direction of travel, it pulls the first rack 510 to move, driving the first gear 421 to rotate. The first gear 421 drives the plow blade 300 to rotate through the second connecting column 420, the second gear 422, the second rack 220, and the third gear 230, thereby reducing the degree of deviation between the plow blade 300 and the direction of travel.

[0036] After the first telescopic cylinder 400 stops moving (i.e., after the plow frame 200 has finished deflecting), the rotation angle of the first gear 421 is not completely consistent with the deflection angle of the plow frame 200. Therefore, the plow blade 300 cannot be oriented exactly in the direction of travel.

[0037] In this embodiment, after the first telescopic cylinder 400 stops moving, the second telescopic cylinder 500 is controlled to move, so that the first gear 421 only rotates without moving. Thus, while ensuring that the deflection angle of the plow frame 200 remains unchanged, the rotation of the first gear 421 is transmitted sequentially through the second connecting column 420, the second gear 422, the second rack 220, and the third gear 230, driving the plow blade 300 to rotate. This further reduces the angle between the plow blade 300 and the direction of travel, thereby reducing the soil resistance encountered by the plow blade 300 when plowing, and improving plowing efficiency and plowing effect.

[0038] In some preferred embodiments, the plow head of the multi-angle adjustable high-efficiency plow can also be equipped with a detection and control system. This system detects the direction and distance of movement of the traction push plate 410 of the first telescopic cylinder 400. Based on the installation and structural dimensions of the U-shaped frame 100, plow frame 200, and first gear 421, it calculates the deflection angle of the plow frame 200 and the rotation angle of the plow blade 300. Based on the angular difference between the deflection angle of the plow frame 200 and the rotation angle of the plow blade 300, it calculates the distance the first rack 510 needs to move to rotate the first gear 421 corresponding to this angular difference. The second telescopic cylinder 500 is then controlled to move the first rack 510 this distance, thereby ensuring that the plow blade 300 is precisely oriented in the direction of travel.

[0039] The first rack 510 is provided with a second slide groove 511, and the push plate 410 is connected to a first slider 423 below it. The first slider 423 is slidably disposed in the second slide groove 511.

[0040] In this embodiment, by providing a second sliding groove 511 on the first rack 510 and connecting a first slider 423 below the push plate 410, the first slider 423 slides within the second sliding groove 511. This allows the push plate 410 to move more smoothly and steadily relative to the first rack 510 under the guidance of the second sliding groove 511. Furthermore, the second sliding groove 511 and the first slider 423 prevent the push plate 410 from shifting in the direction perpendicular to the first rack 510, ensuring that both first gears 421 located on either side of the first rack 510 maintain good meshing with it, thus making the rotation of the first gears 421 and the movement of the first rack 510 smoother.

[0041] The plow blade 300 includes a plow column 310 that can rotate relative to the plow frame 200 and a plow blade 320 disposed below the plow column 310. The plow column 310 is provided with a vertically movable blade 330 for cutting the material wrapped around the plow column 310. The blade 330 has a serrated edge.

[0042] When tangled material (such as straw, weeds, roots, etc.) on the plowshare 310 causes blockage between the plowshare 310 and the plow frame 200, or after the plow blade 300 has plowed a row, the plow blade 300 is controlled to detach from the soil. Then, the up-and-down movement of the blade 330 cuts the tangled material on the plowshare 310, causing it to break and detach from the plow blade 300. This reduces the risk of blockage between the plowshare 310 and the plow frame 200, thereby ensuring the working efficiency of the plow blade 300 and improving the plowing effect.

[0043] Furthermore, in this embodiment, the cutting edge of the blade 330 is set to a serrated shape, which makes the cutting effect of the blade 330 on the wrapped material better.

[0044] To enable the blade 330 to move up and down, in some embodiments, a plurality of sleeves 240 are fixedly provided at the bottom end of each plow frame 200. The plurality of sleeves 240 are fitted one-to-one around the plurality of plow columns 310, and each sleeve 240 is provided with a vertical through groove 241. A wavy third sliding groove 311 is provided on the plow column 310 along the circumference. A slidable second slider 331 is provided in the third sliding groove 311. The second slider 331 passes through the through groove 241 and connects to the blade 330.

[0045] In this embodiment, a wave-shaped third groove 311 is provided circumferentially on the plow column 310, and a sleeve 240 with a vertical through groove 241 is fitted on the outside of the plow column 310. When the plow column 310 rotates, the second slider 331 moves along the third groove 311 and moves up and down along the through groove 241 under the push of the groove wall of the third groove 311, thereby driving the blade 330 to move up and down to cut the wrapped material. This solution is not only simple in structure and low in cost, but also stable in operation.

[0046] In other embodiments, the blade 330 may be connected to a motor, and the movement and cutting of the blade 330 can be controlled by controlling the start and stop of the motor.

[0047] The plowstock 310 is provided with two third sliding grooves 311, and the two third sliding grooves 311 are symmetrically arranged with respect to the cross-section of the plowstock 310. Each third sliding groove 311 is provided with a second slider 331, and the two second sliders 331 pass through the through groove 241 and are connected to the two blades 330, so that the two blades 330 move synchronously in opposite directions.

[0048] In this embodiment, by providing two blades 330 on each plowshare 310, the cutting range of the blades 330 is expanded. Simultaneously, the two blades 330, moving synchronously in opposite directions, can cooperate with each other during the cutting of the wrapped material, pulling on the material and thus improving the cutting effect.

[0049] The two blades 330 located on the same plowstock 310 always partially overlap.

[0050] In this embodiment, the two blades 330 on the same plowstock 310 are always partially overlapping. On the one hand, this can prevent hard impurities from getting stuck between the two blades 330 when they are completely separated, thus preventing the blades 330 from getting stuck. On the other hand, the serrated cutting edge of the overlapping part can form a shearing action during the synchronous reverse movement of the two blades 330, thereby improving the cutting effect on the entangled material.

[0051] The plowshare 310 is configured to rotate in both directions as the blade 330 cuts the entangled material.

[0052] In this embodiment, the plow column 310 is set to rotate in both directions, so that while the blade 330 moves up and down, the plow blade 320 swings back and forth. On the one hand, it can break free from and throw off the entangled material, and on the other hand, it can work with the moving blade 330 to make the blade 330 cut the entangled material better.

[0053] The second telescopic cylinder 500 can repeatedly extend and retract according to a preset telescopic frequency and distance, thereby causing the plow column 310 to rotate in a forward and reverse cycle according to a certain rotation angle and rotation frequency.

[0054] Preferably, the plowshare 310 is configured to oscillate back and forth at a high frequency to improve the plow blade 320's ability to free the entangled object.

[0055] The multi-angle adjustable high-efficiency ploughing head may also generally include a connecting frame 600. The connecting frame 600 is disposed on the U-shaped frame 100 and the cover plate 110 for connecting the ploughing machine.

[0056] like Figure 1 As shown, the connecting frame 600 includes four supports, one end of which is connected together, and the other end is connected to the U-shaped frame 100 and the cover plate 110. Two supports are connected to the U-shaped frame 100, and the other two supports are connected to the cover plate 110 to improve structural stability.

[0057] Preferably, the connecting frame 600 is detachably connected to the U-shaped frame 100 and the cover plate 110 to reduce installation and maintenance costs.

[0058] The specific working process of the multi-angle adjustable high-efficiency ploughing head provided by the present invention will be described in conjunction with the above embodiments: Before use, first connect the connecting frame 600 of the multi-angle adjustable high-efficiency ploughing head to the ploughing machine. The ploughing machine pulls the connecting frame 600, causing the multi-angle adjustable high-efficiency ploughing head to fall and move along the direction of travel, thereby causing the plow blades 300 to plough the land.

[0059] When tangled material (such as straw, weeds, roots, etc.) on the plowshare 310 causes blockage between the plowshare 310 and the plow frame 200, or after the plow blade 300 has plowed a row, the connecting frame 600 is pulled upwards to detach the plow blade 300 from the soil. After the plow blade 300 is detached from the soil, the extension and retraction of the second telescopic cylinder 500 causes the first rack 510 to move back and forth, thereby driving the first gear 421 meshing with it to rotate forward and backward, which in turn drives the second connecting column 420 and the second gear 422 to rotate forward and backward synchronously. The rotation of the second gear 422 drives the movement of the second rack 220 meshing with it, thereby driving the third gear 230 to rotate forward and backward synchronously. The forward and backward rotation of the third gear 230 causes the plow blade 300 to swing back and forth, and at the same time causes the blades 330 on the plow blade 300 to move up and down, thereby cutting and freeing the tangled material on the plow blade 300.

[0060] When land conditions change, such as when the width of the land changes, the plow blade 300 is first lifted off the land by activating the connecting frame 600. Then, the first telescopic cylinder 400 is controlled to move the push plate 410, causing the synchronously moving second connecting column 420 to move and deflect the plow frame 200, thus adapting the plowing range of the plow blade 300 to the width of the land. During the movement of the second connecting column 420, since the first gear 421 and the first rack 510 on it remain engaged, the second connecting column 420 rotates synchronously, thereby driving the second gear 422 to rotate. The rotation of the second gear 422 drives the second rack 220, which meshes with it, to move, thereby driving the third gear 230 to rotate, causing the plow blade 300 to rotate away from the deflection direction of the plow frame 200. This reduces the degree of skew between the plow blade 300 and the direction of travel after the plow blade 300 row spacing is adjusted. After the first telescopic cylinder 400 stops operating, the second telescopic cylinder 500 is controlled to move, causing the first rack 510 to move, thereby driving the plow blade 300 to rotate, so that the plow blade 300 faces the direction of travel.
