[0031] In the aspect of the weeding operation of existing agricultural machinery, the weeding agricultural machinery usually has a single function. Generally, a weeding machine either weeds between crop rows or weeds between crop plants or seedlings. This results in a low weeding efficiency of crops and increases the weeding cost of crops.

[0032] In view of the above problems, the present application designs a weeding device and its weeding machine. The weeding device includes a fixing mechanism, a lifting mechanism, and a weeding mechanism. It can be fixed to a target traveling device through the fixing mechanism, so that the weeding device realizes automatic weeding as the target traveling device moves. The lifting mechanism can adjust the distance of the weeding mechanism relative to the crop planting surface, thereby improving the weeding reliability of the weeding mechanism. In addition, the weeding mechanism designed in this solution simultaneously includes an inter - plant weeding device and a row - to - row weeding device, so as to simultaneously remove other plant weeds between crop rows and between plants, thereby improving the weeding efficiency.

[0033] Based on the above ideas, the present application first provides a weeding device, such as Figure 1 shown.

[0034] For the weeding device designed above, the weeding mechanism 10 may include an inter-row weeding device 110 and an in-row weeding device 120. Among them, the inter-row weeding device 110 is used for weeding between crop plants, and the in-row weeding device 120 is used for weeding within crop rows. Here, it should be noted that in the case of crop planting, it is generally carried out row by row. The area between crop rows described in this solution refers to the area between every two rows of crops, and the area around the crop plants themselves is referred to as the area between crop plants. In addition, the weeding described in this solution does not only refer to weeds, but also represents all other plants except the planted crops.

[0035] For the weeding device designed above, the height of the weeding mechanism 10 in the weeding device relative to the planting surface can be adjusted by the lifting mechanism 20, so that the weeding mechanism 10 is located at an appropriate weeding height. In this case, the weeding device is arranged on the target traveling device through the fixing mechanism 30, and the target traveling device can move in the crop planting area to drive the weeding device to move, so that the weeding mechanism 10 removes the weeds in the crop planting area, realizing automatic weeding.

[0036] The weeding device designed in this solution includes a fixing mechanism, a lifting mechanism, and a weeding mechanism. Through the fixing mechanism, it can be fixed to the target traveling device, so that the weeding device realizes automatic weeding with the movement of the target traveling device. The lifting mechanism can adjust the distance of the weeding mechanism relative to the crop planting surface, thereby improving the weeding reliability of the weeding mechanism. In addition, the weeding mechanism designed in this solution includes both an inter-row weeding device and an in-row weeding device, so that other plant weeds between crop rows and between crop plants can be removed, thereby improving the weeding efficiency.

[0037] In an alternative embodiment of this embodiment, as Figure 2 shown, the lifting mechanism 20 designed in this solution may include an electric lifting device 210, a follow-up device 220, and a carrying device 230.

[0038] For the lifting mechanism 20 designed above, the electric lifting device 210 is used to drive the follower device 220 and the carrying device 230 to lift through the telescopic movement of the electric push rod, so as to adjust the heights of the follower device 220 and the carrying device 230 relative to the planting surface; the follower device 220 is used to perform follow-up adjustment of the angles and heights of the carrying device 230 relative to the planting surface during the movement of the weeding device.

[0040] Among them, the electric push rod 2150 includes a hollow fixed rod 21510 and a telescopic rod 21520, the push rod connecting member 2160 includes a first connecting rod 21610 and a second connecting rod 21620, the first end of the first connecting rod 21610 is connected to the first end of the second connecting rod 21620, and the first connecting rod 21610 and the second connecting rod 21620 are perpendicular to each other; the first end of the first fixing plate 2110 is fixedly connected to the fixing mechanism 30, the first end of the hollow fixed rod 21510 is fixedly connected to the first surface of the first fixing plate 2110, the first ends of the first pull rod 2120, the second pull rod 2130, and the third pull rod 2140 are all rotatably connected to the first fixing plate 2110, the first end of the telescopic rod 21520 is embedded in the hollow fixed rod 21510, the second end of the telescopic rod 21520 is fixedly connected to the second end of the first connecting rod 21610, and the second ends of the second pull rod 2130 and the third pull rod 2140 are rotatably connected to the second end of the second connecting rod 21620; a protrusion 21630 is provided on the second connecting rod 21620, and the second end of the first pull rod 2120 is rotatably connected to the protrusion 21630; among them, the second pull rod 2130 and the third pull rod 2140 are parallel to each other, and the height of the first pull rod 2120 relative to the planting surface is greater than the heights of the second pull rod 2130 and the third pull rod 2140 relative to the planting surface.

[0041] For the electric lifting device designed above, the telescopic rod 21520 in the electric push rod 2150 extends or contracts in the hollow fixed rod 21510, and then drives the first pull rod 2120, the second pull rod 2130, and the third pull rod 2140 to rotate downward or upward, so that the electric lifting device 210 drives the follower device 220 and the carrying device 230 to descend or ascend, thereby adjusting the heights of the follower device 220 and the carrying device 230 relative to the planting surface.

[0042] As a specific implementation, please continue to refer to Figure 3, the follow-up device 220 includes: a connecting portion 2210, a first rotating plate 2220, a second rotating plate 2230, and a rotating rod 2240. The first rotating plate 2220 is fixedly connected to the second connecting rod 21620 through the connecting portion 2210. The first rotating plate 2220 and the second rotating plate 2230 are connected through the rotating rod 2240 to form a parallelogram structure. The second rotating plate 2230 is fixedly connected to the carrying device 230.

[0043] The carrying device 230 includes a support rod 2310, a first carrying member 2320, and a second carrying member 2330. The first carrying member 2320 includes a first fixing portion 23210 and a first carrying portion 23220 connected to the first fixing portion 23210. The second carrying member 2330 includes a second fixing portion 23310 and a second carrying portion 23320 connected to the second fixing portion 23310. Among them, the first carrying portion 23220 is used to carry the inter-row weeding device 110, and the second carrying portion 23320 is used to carry the in-row weeding device 120.

[0044] The second rotating plate 2230 is fixedly connected to the first position of the support rod 2310. The first fixing portion 23210 is movably sleeved between the first end of the support rod 2310 and the first position. In this way, the first carrying portion 23220 carrying the inter-row weeding device 110 can move between the first end of the support rod 2310 and the first position, so as to realize the position adjustment of the inter-row weeding device 110; a profiling wheel is provided at the second end of the support rod 2310. The second fixing portion 23310 is movably sleeved between the second end of the support rod 2310 and the first position. In this way, the second carrying portion 23320 carrying the in-row weeding device 120 can move between the second end of the support rod 2310 and the first position, so as to realize the position adjustment of the in-row weeding device 120.

[0045] For the above-designed follow-up device 220, the rotating rod is used to rotate according to the height change of the crop planting surface during the movement process to adjust the height and angle of the carrying device relative to the planting surface. Specifically, the profiling wheel at the second end of the support rod 2310 contacts the planting surface. During the movement of the weeding device, the height of the planting surface may change. In the case where the height of the planting surface changes, the height change is transmitted to the support rod 2310 through the profiling wheel, and then transmitted to the second rotating plate 2230 through the support rod 2310, so that the rotating rod 2240 rotates, and further enables the follow-up device 220 to adjust the height and angle of the carrying device relative to the planting surface according to the height change of the crop planting surface during the movement process.

[0046] In an alternative embodiment of this embodiment, as Figure 4 and Figure 5As shown in the figure, the inter-row weeding device 110 includes a weeding connecting rod 1110, an angle adjusting member 1120, and a weeding member 1130. The first end of the weeding connecting rod 1110 is fixedly connected to the lifting mechanism 20. Specifically, the weeding connecting rod 1110 is connected to the aforementioned first bearing portion 23220, and the second end of the weeding connecting rod 1110 is connected to the weeding member 1130 through the angle adjusting member 1120.

[0047] With the above-designed angle adjusting member 1120, the inclination angle of the weeding connecting rod 1110 relative to the planting surface can be adjusted, so as to adjust the inclination angle of the weeding member 1130 relative to the planting surface.

[0048] As a possible implementation manner, the weeding member 1130 designed in this solution includes a rotary bearing 11310, an inter-row weeding disk 11320, and a driving disk 11330. A plurality of first convex structures 11340 protruding outward and horizontal with the outer peripheral edge are provided on the outer peripheral edge of the inter-row weeding disk 11320. A plurality of second convex structures 11350 are inclinedly provided on the outer peripheral edge of the driving disk 11330. The central axis portions of both the inter-row weeding disk 11320 and the driving disk 11330 are connected to the rotary bearing 11310, and the inter-row weeding disk 11320 is arranged between the driving disk 11330 and the rotary bearing 11310.

[0049] With the above-designed weeding member 1130, when weeding, the plurality of second convex structures 11350 are used to contact and rub against the planting surface. The rotary bearing 11310 drives the driving disk 11330 to rotate, and the driving disk 11330 rotates and then drives the inter-row weeding disk 11320 to rotate, so that the plurality of first convex structures 11340 of the inter-row weeding disk 11320 rub against the target grass plants, thereby realizing the weeding of the target grass plants. And in this solution, a plurality of first convex structures 11340 are designed such that when the inter-row weeding device 110 weeds the crops, the crops can be located between two first convex structures while weeding, and thus the effect of not damaging the crops can be achieved.

[0050] As a possible implementation manner, the driving disk 11330 and the inter-row weeding disk 11320 designed in this solution can be made of rubber material, so that the driving disk 11330 deforms when contacting the ground, increasing the contact area with the ground. At the same time, the inter-row weeding disk 11320 made of rubber material can increase the friction force with the weeds, thereby improving the weeding effect.

[0051] In an alternative implementation manner of this embodiment, please continue to refer to Figure 4 and Figure 5, the angle adjustment member 1120 may include an angle adjustment plate 11210, on which a plurality of bolt holes 11220 are formed. The angle adjustment plate 11210 is used to fix the weeding connecting rod 1110 to bolt holes at different positions through bolts, so as to adjust the inclination angle of the weeding connecting rod 1110 relative to the planting surface, and further adjust the inclination angle of the weeding member 1130 relative to the planting surface.

[0052] In an alternative embodiment of the present embodiment, as Figure 6 shown, the rotary bearing 11310 may be formed by a bushing 113110, a hole retaining ring 113120, a shaft retaining ring 113130, a bearing 113140 and a shaft body 113150. Of course, other bearing forms can also be adopted in this solution, and specific adaptation can be made according to the actual application scenario.

[0053] In an alternative embodiment of the present embodiment, as Figure 7 shown, the inter-row weeding device 120 may include an inter-row weeding connecting rod 1210 and a cutting member 1220. The first end of the inter-row weeding connecting rod 1210 is fixedly connected to the lifting mechanism 20. Specifically, the first end of the inter-row weeding connecting rod 1210 may be fixedly connected to the aforementioned second bearing portion 23320, and the second end of the inter-row weeding connecting rod 1210 is connected to the cutting member 1220.

[0054] For the inter-row weeding device 120 designed above, the cutting member 1220 moves as the weeding device moves. During the movement, the cutting member 1220 cuts the plants between the rows on the planting surface, so as to achieve inter-row weeding.

[0055] The present application also provides a weeding machine, as Figure 8 shown, the weeding machine includes a traveling device A and the weeding device B described in any of the foregoing alternative embodiments. Among them, the weeding device B is fixedly connected to the traveling device A through a fixing mechanism 30. When the traveling device A is traveling, inter-row weeding and in-row weeding of the crops are performed through the weeding device B.

[0056] For the weeding machine designed above, since it includes the aforementioned weeding device, the designed weeding machine can achieve automatic weeding. The lifting mechanism can adjust the distance between the weeding mechanism and the crop planting surface, so as to improve the weeding reliability of the weeding mechanism. In addition, the weeding machine designed in this solution includes both an in-row weeding device and an inter-row weeding device, so that other plant weeds between the rows and in the rows of the crops can be removed, thereby improving the weeding efficiency.
