Description

A soil loosening structure and weeding device between Chinese medicinal materials under the forest

Technical Field

The invention belongs to the technical field of agriculture and forestry planting, and in particular relates to a soil loosening structure and a weeding device between Chinese medicinal materials under the forest.

Background Art

With the transformation of the domestic economic development model from extensive to intensive, achieving sustainable economic development is a requirement and an inevitable trend. Among them, relying solely on limited wild resources to ensure the acquisition of Chinese medicinal materials is not only difficult to meet market demand, but may also cause great damage to wild resources. In order to alleviate the contradiction between supply and demand, artificial introduction and cultivation is imperative. Planting Chinese medicinal crops under the forest as a typical forestry composite production and management method can improve the utilization efficiency of limited land resources, ensure farmers' increased production and income, and promote the development of local circular economy.

Before planting, the existing Chinese medicinal materials under the forest need to be cultivated and weeded between the Chinese medicinal materials planned under the forest to meet the soil planting conditions of Chinese medicinal materials. As the under-forest planting method has become a new development, corresponding weeding equipment is needed to carry out weeding operations to free up manpower. The existing weeding equipment basically cuts and weeds by rotary tillage, and the soil is not loosened. Due to the lack of loosening action during the inter-plant planting of Chinese medicinal materials, the compaction of the soil makes the porosity between the Chinese medicinal materials poor, which seriously affects their growth and the development of the root system; in addition, the stones in the soil will affect the bulk density of the soil, making the nutrients in the soil easily impacted by rainwater, resulting in a fast flow rate of soil and nutrients, and also affecting the smooth growth of the root system of Chinese medicinal materials.

In view of this, the present invention is proposed.

Summary of the invention

The present invention provides a soil loosening structure between Chinese medicinal materials under a forest. Two soil loosening claws that can slide laterally are arranged on a third mounting frame, and a driving mechanism is used to drive the soil loosening teeth on the soil loosening claws to move laterally and staggeredly, so that the corresponding soil can be loosened, thereby effectively preventing the soil from being compacted, and improving the porosity between Chinese medicinal materials, thereby ensuring the growth of subsequently planted Chinese medicinal materials and the development of the root system.

In the description of the present invention, it should be noted that, unless otherwise clearly specified and limited, the terms "installed", "connected", and "connected" should be understood in a broad sense, for example, it can be a fixed connection, a detachable connection, or an integral connection; it can be a mechanical connection or an electrical connection; it can be a direct connection or an indirect connection through an intermediate medium. For ordinary technicians in this field, the specific meanings of the above terms in the present invention can be understood according to specific circumstances.

As shown in FIGS. 7 to 11 , the soil loosening structure between Chinese medicinal materials under forests of the present invention comprises a third mounting frame 8 which can reciprocate vertically;

Two loosening claws 9 are slidably disposed on the third mounting frame 8 in a transverse manner. The loosening claws 9 at least include a plurality of loosening teeth 91 extending vertically downward. The loosening teeth 91 on the two loosening claws 9 correspond to each other and are fitted together.

The driving mechanism 10 is arranged on the third mounting frame 8, and its driving end can simultaneously drive the two loosening claws 9 to move toward or away from each other.

In the present invention, the third mounting frame 8 is arranged at the bottom of the weeding device. Specifically, two cylinders are symmetrically arranged on the third mounting frame 8. The driving end of the cylinder is connected to the third mounting frame 8, and the base thereof is fastened to the bottom side wall of the weeding device by bolts. Thus, the third mounting frame 8 can be driven to reciprocate vertically relative to the bottom of the weeding device through the driving action of the cylinder.

Wherein, two loosening claws 9 that can slide laterally are arranged on the third mounting frame 8, and the direction of its lateral movement is perpendicular to the direction of travel of the weeding device. Both loosening claws 9 are provided with a plurality of loosening teeth 91 extending vertically, and each loosening tooth 91 is arranged at intervals in the lateral direction. The loosening teeth 91 on the two loosening claws 9 are arranged one by one on the left and right, and the relative side walls are arranged in a fitting manner. Then, the two loosening teeth 91 can be driven by the driving mechanism 10 arranged on the third mounting frame 8, so that the two loosening teeth 91 can slide laterally with the corresponding loosening claws 9, thereby forming the staggered movement of adjacent loosening teeth 91. During specific implementation, the third mounting frame 8 is driven downward by the cylinder start, so that the loosening teeth 91 are inserted into the soil, and the driving mechanism 10 is used to drive the loosening teeth 91, so that the plurality of loosening teeth 91 are staggered laterally, so that the corresponding soil can be loosened. Because the loosening operation effectively prevents the compaction of the soil, the porosity between the plants of Chinese medicinal materials is improved, thereby ensuring the growth of the subsequent planting of Chinese medicinal materials and the development of the root system.

Furthermore, the width of each loosening tooth 91 of the left loosening claw member 9 gradually decreases from the middle of the loosening claw member 9 to both sides, forming an outer contour of an isosceles triangle.

In the present invention, the width of the loosening teeth 91 on at least the loosening claw 9 on the left side is different, and the width gradually decreases from the middle position of the loosening claw 9 to both sides. Among them, the front side of the loosening teeth 91 on the left side (the front side is the forward direction of the weeding device) has an inclined surface, so that the end surface of each loosening tooth 91 is formed as two discontinuous and symmetrical inclined surfaces as a whole, and isosceles triangles are formed with the outer periphery of the entire rear side.

In the specific implementation process, when the weeding device is moving, the loosening teeth 91 on the left side are arranged in a symmetrical inclined plane, which can reduce the travel resistance of the whole weeding device; in addition, due to the setting of the inclined plane, the stones outside the soil can be pushed to roll to both sides, and because the loosening teeth 91 move laterally and staggered, the movement state is used to push the stones, and the stones are also prevented from being stuck between two adjacent loosening teeth 91. By moving the stones on the soil to both sides of the loosening claw 9, the influence of the soil bulk density can be reduced, the loss of soil can be avoided, and the root system of the planted Chinese herbal medicine can grow smoothly.

Furthermore, the two loosening claws 9 further include a moving block 92 arranged parallel to the third mounting frame 8, and a plurality of loosening teeth 91 are correspondingly arranged on the lower side of the moving block 92;

The third mounting frame 8 is provided with a plurality of guide rods 83 protruding outwards, and the upper end of the moving block 92 is provided with a connecting block 93 . The connecting block 93 is provided with a through hole, and the guide rods 83 pass through the through hole to connect with the third mounting frame 8 .

In the present invention, the loosening claws 9 on the left and right sides include a moving block 92 arranged in parallel with the third mounting block, and the two moving blocks 92 are arranged side by side, wherein the loosening teeth 91 on the left and right sides are respectively arranged on the two moving blocks 92. A connecting assembly is arranged between the third mounting frame 8 and the moving block 92, wherein the connecting assembly includes a plurality of guide rods 83 arranged at the end of the third mounting frame 8 and a connecting block 93 connected to the moving block 92, and a through hole is arranged on the connecting block 93, and the guide rod 83 is passed through the through hole to connect with the third mounting frame 8, so that the two moving blocks 92 are assembled on the third mounting frame 8.

Furthermore, a convex head is provided at one end of the guide rod 83 away from the third mounting bracket 8, and a second telescopic spring 94 is sleeved on the outside of each guide rod 83;

The two ends of the second telescopic spring 94 are respectively against the convex head and the connecting block 93 or the two ends of the second telescopic spring 94 are respectively against the third mounting bracket 8 and the connecting block 93.

In the present invention, a convex head is provided at the front end of the guide rod 83, and a second telescopic spring 94 is sleeved on the outside thereof, wherein the two ends of the second telescopic spring 94 can be respectively provided between the convex head and the connecting block 93 or between the third mounting frame 8 and the connecting block 93, thereby being able to ensure that the movable block 92 is always in a tensioned state during the lateral movement process, so that the movable block 92 can accurately reach the preset position.

Furthermore, the driving mechanism 10 includes a second driving motor 101 and a cam 102, wherein the second driving motor 101 is disposed on the third mounting frame 8; the cam 102 is connected to the driving end of the second driving motor 101;

The two moving blocks 92 are provided with upwardly extending abutting blocks 103 , and the two sides of the cam 102 are respectively arranged opposite to the two abutting blocks 103 .

In the present invention, the second driving motor 101 in the driving mechanism 10 is arranged on the third mounting frame 8, and the driving end thereof is connected to a cam 102, and the two sides of the cam 102 correspond to the abutment blocks 103 on the two moving blocks 92 respectively. When the second driving motor 101 drives the cam 102 to rotate, the loosening teeth 91 can be staggered to move toward or away from each other, so that the two rows of loosening teeth 91 can perform loosening operations on one side; on the other side, because the opposite side walls of the two loosening teeth 91 are arranged in close contact, they can act as cutters. .

Furthermore, it also includes:

The fourth mounting frame 11 can be horizontally reciprocated relative to the loosening claw member 9, and the fourth mounting frame 11 is rotatably connected to the loosening claw member 9;

The crushing claw member at least includes a plurality of crushing teeth 111 extending vertically downward and arranged at intervals along the length direction of the fourth mounting frame 11 .

The present invention also includes a fourth mounting frame 11 that is rotatably connected to the loosening claw member 9, and the fourth mounting frame 11 can move horizontally forward and backward relative to the loosening claw member 9. The vertically extending crushing teeth 111 arranged on the fourth mounting frame 11 are located at the front side of the loosening claw member 9, and after the front and rear projection, the multiple crushing teeth 111 are located between the intervals of two adjacent loosening teeth 91 to avoid interference with the loosening teeth 91 on the rear side. As the weeding device moves forward, the multiple crushing teeth 111 can longitudinally cut and crush the passing soil blocks, weeds and branches, and then cooperate with the lateral cutting of the loosening teeth 91, so that the weeds and branches in the process of the weeding device can be cut, and cooperate with the lateral movement of the loosening teeth 91 to move the stones, so that the dual operations of weeding and loosening the soil between the Chinese medicinal materials under the forest can be effectively performed.

Furthermore, fixed blocks 112 are symmetrically arranged on both sides of the fourth mounting frame 11, and the fourth mounting frame 11 is rotatably connected to the fixed blocks 112 on both sides via a rotating shaft, and the fixed blocks 112 can reciprocate horizontally relative to the loosening claw member 9;

The third mounting frame 8 is provided with a fixing rod 81 extending along the length direction thereof, and the fixing rod 81 is provided with a plurality of wedge blocks 82 at intervals along the length direction thereof;

The fixing block 112 is provided with a butt rod 115 which can butt against the wedge block 82 .

In the present invention, the fourth mounting frame 11 is installed in such a way that fixed blocks 112 are arranged at both ends thereof, and the fixed blocks 112 can reciprocate forward and backward relative to the loosening claw member 9. An axial hole is arranged on the fixed block 112, and a rotating shaft matching the axial hole is arranged at both ends of the fourth mounting frame 11. A fixed rod 81 is arranged on the third mounting frame 8, and wedge blocks 82 are arranged at intervals along the length direction of the fixed rod 81, and at the same time, a vertically upwardly extending abutting rod 115 is arranged on the fixed block 112, and the abutting rod 115 is arranged to abut against the wedge block 82.

In the specific implementation process, when the loosening tooth 91 on the left side moves horizontally, the fixed block 112 moves horizontally with the push rod 115. Due to the pressing effect of the push rod 115 and the wedge block 82, the crushing tooth 111 moves forward and backward, and because the crushing tooth 111 can rotate during the movement, the crushing tooth 111 can be tilted to cut the weeds and branches longitudinally when moving forward, and when the crushing tooth 111 moves backward, it can maintain a vertical state again, so that the crushing tooth 111 will not be stuck in the weeds and branches. When the weeds, branches or stones are too hard to cut, the crushing tooth 111 can rotate with the fourth mounting frame 11, so as to achieve the avoidance function.

Furthermore, two limit blocks 114 are provided on the side wall of any fixed block 112, namely a first limit block 114 and a second limit block 114; a stop rod 113 located between the two limit blocks 114 is provided at the outer end of the rotating shaft;

When the blocking rod 113 abuts against the first limiting block 114 , the crushing tooth 111 is in a vertical state; when the blocking rod 113 abuts against the second limiting block 114 , the crushing tooth 111 is located in front of the loosening tooth 91 on the left side.

In the present invention, two limit blocks 114 are arranged on the fixed block 112, so that the rotation range of the crushing tooth 111 is limited to the vertical state and the inclined state and the front side of the left loosening tooth 91. This can effectively prevent the crushing tooth 111 from being unable to avoid thicker weeds and branches, and the crushing tooth 111 can be cut in an inclined state without affecting the normal operation of the loosening tooth 91 on the rear side.

Furthermore, the lower end of the crushing tooth 111 is provided with an inclined surface, which is gradually inclined downward from left to right.

In the present invention, the inclined surface provided at the lower end of the crushing tooth 111 is inclined downward along the direction in which the weeding device moves, which can effectively protect the end of the crushing tooth 111. The tip of the end of the crushing tooth 111 is provided to facilitate the insertion and removal of the crushing tooth 111 from the soil.

The present invention further provides a weeding device comprising a vehicle body 1 and a soil loosening structure having any of the above embodiments.

Another embodiment of the present invention: Referring to FIGS. 1-6 , the vehicle body 1 is further provided with a weeding structure, which includes a first mounting frame 3 , both ends of which are bent and extended downward to form a mounting opening 31 ;

Two movable frames 4 arranged up and down can be slidably disposed in the installation opening 31 in a transverse manner. A plurality of clamping portions 41 extending outwardly and protruding are disposed at intervals on the front sides of the two movable frames 4. The clamping portions 41 in the upper and lower movable frames 4 are staggered in sequence to form a clamping opening.

The trigger mechanism 5 is disposed on the first mounting frame 3 and the movable frame 4, and is used to drive the two movable frames 4 to slide in opposite directions.

The first mounting frame 3 has two ends bent and extended downward to form a mounting opening 31;

Two movable frames 4 arranged up and down can be slidably disposed in the installation opening 31 in a transverse manner. A plurality of clamping portions 41 extending outwardly and protruding are disposed at intervals on the front sides of the two movable frames 4. The clamping portions 41 in the upper and lower movable frames 4 are staggered in sequence to form a clamping opening.

The trigger mechanism 5 is disposed on the first mounting frame 3 and the movable frame 4, and is used to drive the two movable frames 4 to slide in opposite directions.

In the present invention, a second weeding mechanism is also provided, which includes a first mounting frame 3 which is U-shaped as a whole and opens downward, and the first mounting frame 3 can be fixed or rotatably arranged on the weeding device. In the mounting opening 31 of the first mounting frame 3, at least a plurality of mounting holes are symmetrically arranged up and down, and a mounting rod is fixedly installed in the mounting hole. A plurality of sliding holes slidably connected to the mounting rod are provided at both ends of the corresponding movable frame 4. Of course, the sliding holes at both ends of the movable frame 4 can be connected to form a sliding hole, and the movable frame 4 is slidably sleeved in the mounting rod. The two movable frames 4 are arranged in parallel up and down. A spring is sleeved on the outer side of the mounting rod to ensure the positioning of the movable frame 4 after installation and the reset function after the activity.

The front side of the movable frame 4 is the direction in which the entire weeding device moves. A clamping portion 41 protruding from the side wall is provided on the front side of the movable frame 4, and the upper and lower clamping portions 41 at corresponding positions are alternately arranged in sequence to form a clamping opening. It should be noted that the clamping opening can be the clamping opening formed by the two upper and lower corresponding clamping portions 41 having a spacing in the transverse direction; of course, the two upper and lower corresponding clamping portions 41 can fit each other, and the clamping opening is formed by a spacing between the other group of upper and lower corresponding clamping portions 41. The molding methods of the two clamping openings are essentially the same, depending on the distribution of the spacing between the two upper and lower corresponding clamping portions 41 in the initial stage.

A trigger mechanism 5 is also provided on the first mounting frame 3 and the movable frame 4. The two movable frames 4 can slide in corresponding opposite directions through the driving action of the trigger mechanism 5, so that the clamping opening can gradually reduce the opening size.

Specific implementation method: During the movement of the weeding device, a plurality of rotary tillage blades 23 are driven to rotate synchronously by a third driving motor relatively arranged at the front side of the weeding device, so as to cooperate in cutting the weeds and branches passing by; then, after passing through the second weeding mechanism, half of the cut weeds and branches are exposed to the outside, and during the movement of the weeding device, the weeds and branches will move to the clamping opening composed of a plurality of clamping parts 41. At this time, by starting the trigger mechanism 5, the upper and lower clamping parts 41 move laterally toward or away from each other with the movable frame 4, thereby gradually reducing the opening size of the clamping opening, so as to clamp the weeds and branches. As the weeding device moves, the weeds and branches can be uprooted, so as to cut and uproot the weeds and branches during the movement, so that the weeding is more thorough and the weeding effect is effectively improved.

Furthermore, the orthographic projections of the clamping portions 41 in the upper and lower movable frames 4 in the transverse direction at least partially overlap.

In the present invention, the clamping portion 41 in the upper movable frame 4 extends outward from the front side thereof for a distance and then bends and extends downward until it has a certain overlap area with the clamping portion 41 in the lower movable frame 4, then bends and extends forward, and is arranged opposite to the extension portion of the lower movable frame 4. By designing the upper and lower movable frames 4 to have an overlapped portion, in order to allow corresponding forces to be applied on both sides of the overlapped portion when clamping weeds and branches, that is, the upper and lower spacing of the two clamping portions 41 is large and there is no overlapped portion, so that different parts of the weeds and branches are subjected to force, resulting in the weeds and branches being squeezed, broken and deformed, and the effect of always clamping cannot be achieved, and thus the weeds and branches cannot be more thoroughly removed during the movement of the weeding device.

Furthermore, the trigger mechanism 5 comprises,

Two trigger fixing heads 55 are respectively arranged at the rear side of the movable frame 4, and the projections of the two trigger fixing heads 55 in the vertical direction have a spacing;

The two trigger cone heads 54 are connected in sequence up and down through the pull rope 52, and the two trigger fixing heads 55 are respectively in contact with different side positions of the two trigger cone heads 54;

The first driving motor 51 has a driving end connected to the pull rope 52 and is used to reel in the pull rope 52 .

In the present invention, trigger fixing heads 55 protruding vertically outward are fixedly disposed on the rear side walls of the two movable frames 4, wherein the trigger fixing heads 55 may be cylindrical or at least the side walls of the outer circumference contacting with the subsequent trigger cone head 54 may be arc-shaped. When the two trigger fixing heads 55 are vertically projected downward onto the same plane, the two trigger fixing heads 55 do not overlap and there is a certain distance between them.

The driving end of the first driving motor 51 is connected to a rope winding drum, in which a pull rope 52 is wound. The pull rope 52 is arranged vertically, and two trigger cone heads 54 are arranged at intervals along the extension direction thereof. The head side wall of the trigger cone head 54 close to the cone center can be abutted against two trigger fixed heads 55 when initially unknown. Specifically, during the driving process of the first driving motor 51, the pull rope 52 is straightened and moves upward, and the two trigger fixed heads 55 are squeezed by the trigger cone heads 54, so that the two movable frames 4 move laterally and staggered, so that the clamping opening formed by the two adjacent clamping parts 41 can be gradually reduced, thereby effectively clamping the weeds and branches, and pulling out the weeds and branches as the weeding device moves.

Furthermore, it also includes a second mounting frame 6 connected to the weeding device, and the first driving motor 51 is arranged on the second mounting frame 6;

The first mounting frame 3 is provided with a telescopic assembly 7 which can be telescoped up and down, and the free end of the telescopic assembly 7 is connected to the second mounting frame 6;

The first mounting frame 3 is provided with a through hole, and the pull rope 52 is provided with a stop shoulder 53 whose hole diameter is larger than that of the through hole. The stop shoulder 53 is located between the through hole and the trigger cone head 54 located above.

In the present invention, a second mounting frame 6 is disposed horizontally at the bottom of the weeding device, wherein the first drive motor 51 is fixedly disposed on the second mounting frame 6. The first mounting frame 3 and the second mounting frame 6 are connected by a telescopic assembly 7, so that the components on the first mounting frame 3 can be telescoped vertically toward or away from the second mounting frame 6.

Further, the telescopic assembly 7 comprises:

The telescopic sleeve 71 has one end movably connected to the first mounting frame 3 or the second mounting frame 6 through a ball shaft 74;

The telescopic rod 72 is slidably sleeved in the telescopic sleeve 71, and one end of the telescopic rod 72 is movably connected to the second mounting frame 6 or the first mounting frame 3 through a ball shaft 74;

Preferably, a first telescopic spring 73 is sleeved on the outer sides of the telescopic sleeve 71 and the telescopic rod 72 .

In the present invention, the telescopic assembly 7 specifically includes a telescopic sleeve 71 and a telescopic rod 72 that are slidably sleeved with each other, wherein the ends of the telescopic rod 72 and the telescopic sleeve 71 that are away from each other are universally connected to the first mounting frame 3 or the second mounting frame 6 through a ball shaft 74. In the process of the first driving motor 51 pulling the pull rope 52 upward, firstly, the trigger fixed head 55 and the trigger cone head 54 abut and gradually squeeze each other, so that the two movable frames 4 are staggered and moved horizontally, and the opening of the clamping mouth is gradually reduced; then, when the shoulder 53 on the pull rope 52 abuts against the perforation, the entire first mounting frame 3 can be driven to approach the second mounting frame 6, so that after the clamping mouth is gradually reduced, the first mounting frame 3 drives the clamping part 41 to move upward, thereby providing an upward pulling force, and the weeding device can be more effectively pulled and removed by the moving action.

Specifically, by sleeved the first telescopic spring 73, the clamping portion 41 of the telescopic assembly 7 can be as close to the ground as possible in the initial state, thereby facilitating subsequent clamping operations and ensuring that weeds, branches, etc. can be clamped.

Furthermore, it also includes:

A mounting strip 62, one end of which is connected to the side wall of the second mounting frame 6, and the other end of which extends vertically downward, wherein the mounting strip 62 is provided with a plurality of arc contacts 63 spaced from top to bottom;

One end of the touch rod 32 is connected to the side wall of the first mounting frame 3 , and the other end of the touch rod 32 extends vertically upward and bends to approach the mounting bar 62 .

In the present invention, a mounting bar 62 extending vertically downward is provided on the left or right side of the second mounting frame 6, wherein a plurality of arc contacts 63 are provided at intervals on the plate surface in the extension direction of the mounting bar 62. A touch rod 32 extending upward and bending toward the mounting bar 62 is provided on the first mounting frame 3 on the same side as the mounting bar 62, wherein the touch rod 32 and the arc contact 63 partially overlap in the vertical direction. When the first driving motor 51 drives the pull rope 52 to move, when the first mounting frame 3 moves upward, the touch rod 32 will contact the arc contact 63 on the mounting bar 62, thereby causing the first mounting frame 3 to shift left and right, thereby connecting the end ball shaft 74 of the telescopic assembly 7, and realizing the left and right shift of the entire clamping portion 41. When the roots of weeds and branches have not been pulled out, the soil near them can be loosened by shaking left and right, making it easier for the weeds and branches to be pulled out of the soil; when the weeds and branches are pulled out, the shaking action can shake the soil attached to the roots of the weeds and branches, separating the soil from the weeds and branches.

Furthermore, two reset blocks 61 extending vertically downward are provided on the second mounting frame 6 , and the extending ends of the two reset blocks 61 have inclined surfaces which are arranged opposite to each other and tilted upward. The two inclined surfaces have a height difference which is at least equal to the vertical spacing between the two trigger fixing heads 55 .

In the present invention, two left-right distributed reset blocks 61 are provided on the rear side of the second mounting frame 6, and the reset blocks 61 extend downward. The extended ends of the two reset blocks 61 are provided with inclined surfaces that are relatively inclined, and the height difference between the two inclined surfaces is at least equal to the spacing between the trigger fixing heads 55, preferably equal to the spacing between the trigger fixing heads 55. When the pull rope 52 moves upward under the drive of the first drive motor 51, the left-right distributed trigger fixing heads 55 respectively abut against the inclined surfaces of the two reset blocks 61, so that the lower movable frame 4 moves in the opposite direction of the original staggered movement, and the clamping opening formed by the two clamping parts 41 is reopened, so that the clamped weeds and branches can be loosened. The above-mentioned clamping and weeding action is repeated, so that the weeds and branches between the Chinese medicinal materials under the forest can be quickly and fully weeded.

It should be noted that the vehicle body 1 in the present invention can be a hand-held type or a mechanically powered type. In order to ensure the effect and efficiency of weeding, the above-mentioned loosening structure can be arranged behind the weeding device, and the weeding structure is arranged at the bottom of the weeding device. In the direction of travel of the weeding device, the weeding structure is at the front side of the loosening structure, so that after the weeding operation, the soil can be loosened.

The weeding structure includes a first weeding mechanism 2 arranged at the front side of the weeding device, and a block frame of the first weeding mechanism 2, which is arranged at the bottom of the weeding device, wherein the frame includes at least three mounting columns 21 protruding from the bottom side wall thereof. The mounting columns 21 are on different straight lines in the same plane, and the connecting lines of the mounting columns 21 form an isosceles triangle. A rotary tillage blade 23 is rotatably connected to the mounting column 21, and the orthographic projection of the rotary tillage blade 23 in the direction of travel of the weeding device is overlapped; each rotary tillage blade 23 has a spacing between them perpendicular to the direction of travel of the weeding device, and the rotation of each rotary tillage blade 23 will not interfere.

The rotary tillage heads 23 are cooperatively driven by the pulley and the belt 22, and one of the rotary tillage heads 23 is driven by the third drive motor, so that the rotary tillage heads 23 on at least three mounting columns 21 can be synchronously rotated. On the one hand, the three rotary tillage heads 23 are synchronously rotated, so that weeds and branches encountered in the weeding device during the travel process can be cut off at the same time; on the other hand, the three rotary tillage heads 23 are arranged in a triangular shape and have overlapping parts in the orthographic projection in the travel direction of the weeding device, so that during the travel of the weeding device, one rotary tillage head 23 can be guaranteed to be cleanly cut, and the remaining rotary tillage heads 23 can be used as compensation cutting to ensure the effect of the cutting operation.
