Description

Technical Field

[0001] This utility model belongs to the field of agricultural machinery technology, specifically relating to an anti-tangling weeding device. Background Technology

[0002] In grain planting, mechanical planting is used to form evenly spaced rows. However, during the growth of seedlings from grain seeds, weeds growing between the rows can seriously threaten the growth of seedlings. They not only block sunlight but also compete with seedlings for water and nutrients, so they need to be removed in time. Current weeding tools are of a single type, and weeds easily get tangled in them when weeding, causing them to gradually accumulate. When the weeds accumulate to a certain amount, their volume becomes too large, and they can damage the seedlings on both sides as the weeding tools are moved.

[0003] For example, prior art with publication number CN220776417U discloses a weeding and cultivating device, belonging to the field of agricultural machinery and equipment technology. It includes a frame and a weeding mechanism. The weeding mechanism is mounted on the frame, and the frame is equipped with wheels that can be adjusted vertically. The weeding mechanism includes an adjusting sleeve and a curved plow blade. The adjusting sleeve is mounted on the frame, and the curved plow blade is vertically positioned and fitted inside the adjusting sleeve, allowing it to slide within the sleeve. By adjusting the height of the wheels and the curved plow blade, weeding can be performed between rows of plants in different fields, achieving adjustable weeding depth and improving the weeding effect between rows. While the above solution can achieve weeding between rows, weeds can become entangled in the crank of the weeding mechanism and gradually increase in number, potentially damaging the seedlings on both sides. Summary of the Invention

[0004] Based on this, this application provides an anti-tangling weeding device to solve the technical problem in the prior art where weeding tools are easily entangled with weeds, causing the weeds to damage the seedlings on both sides.

[0006] An anti-tangling weeding device, comprising:

[0007] A towing frame, which can be connected to a towing machine;

[0008] The root-cutting component is provided on the traction frame, and the root-cutting component can cut the roots of weeds by shoveling into the soil.

[0009] A cutting component, disposed on the root-cutting component, is used to cut weeds entangled on the root-cutting component;

[0010] A power component, which is disposed on the root-cutting component, is capable of driving the shearing component to cut weeds.

[0011] Preferably, the root-cutting component includes a blade and a housing disposed behind the blade, the power component is disposed inside the housing, and the shearing component is disposed on the upper side of the housing.

[0012] Preferably, a triangular plate is provided on the rear side of the blade to guide weeds to the cutting assembly.

[0013] Preferably, guide plates extend rearward on both sides of the blade for backfilling soil to the rear side of the blade.

[0014] Preferably, the shearing assembly includes a shearing tooth box disposed in the outer shell and open at the center of the front side, and a shearing tooth plate slidably connected in the shearing tooth box. Both the shearing tooth box and the shearing tooth plate have a plurality of toothed blades formed on their front sides. The power assembly drives the shearing tooth plate to reciprocate along the height direction.

[0015] Preferably, the power assembly includes a rotating wheel rotatably connected to the root-cutting assembly. When the root-cutting assembly moves forward into the soil, the rotating wheel rotates upon contact with the soil. A groove is provided in the middle of the rotating wheel, and several arc-shaped protrusions are distributed circumferentially along the axis of the rotating wheel inside the groove. The lower end of the shearing plate passes through the outer shell and contacts the arc-shaped protrusions.

[0016] Preferably, a spring is provided between the upper end of the shear plate and the inner top end of the shear box.

[0017] Preferably, a cleaning section is provided at the rear end of the outer casing, which can contact the rotating wheel and is used to clean the soil on the rotating wheel.

[0018] Preferably, it further includes an adjustment component, which is disposed on the shearing component. The adjustment component can drive the shearing component to change its height, thereby changing the depth to which the root-cutting component is inserted into the soil.

[0019] Preferably, the adjusting assembly includes a sleeve detachably connected to the traction frame, and a square tube that slides and can be locked inside the sleeve, with the shearing assembly disposed at the lower end of the square tube.

[0020] Compared with the prior art, this application has at least the following advantages:

[0021] This application provides an anti-tangling weeding device. A traction frame is connected to a traction machine (tractor, towing vehicle, etc.). The traction machine lowers the traction frame, causing it to lower root-cutting components. Simultaneously, the traction machine slowly advances, allowing several root-cutting components to enter between rows of seedlings. As the components descend, they follow the traction machine forward, gradually shoveling into the soil. When the root-cutting components have penetrated to the required depth, such as 3-6 cm below the soil surface, effectively severing the roots of most weeds, the traction machine stops driving the traction frame. The machine descends, and the traction mechanism continues to advance. The root-cutting component then severs the roots of the weeds between rows. As the root-cutting component moves forward, the weeds with severed roots will fall down and become entangled or hooked onto it. At this point, the weeds will come into contact with the shearing component. The power component drives the shearing component to operate, causing the weeds in contact with it to be cut off. This process, along with the advancement of the root-cutting component, cuts off the weeds that are entangled or hooked onto it, allowing them to slide off from both sides of the component and away from it. This prevents the weeds from becoming entangled and accumulating on the root-cutting component. This method can cut off weeds entangled on the root-cutting component while removing weeds between rows of seedlings, preventing them from becoming entangled or hooked onto it. This avoids the accumulation of weeds, which increases in volume and weight and can scratch or damage adjacent seedlings. It also avoids the increased forward power required by the traction mechanism due to the increased weight of the accumulated weeds, reducing energy consumption and lowering costs.

The term "and / or" as used herein includes any and all combinations of one or more of the associated listed items.

[0036] Please refer to Figure 1 and Figure 10 In one specific embodiment of this application,

[0037] An anti-tangling weeding device, comprising:

[0038] A traction frame 610, which can be connected to a traction machine;

[0039] The root-cutting component is provided on the traction frame 610, and the root-cutting component can cut the roots of weeds by shoveling into the soil.

[0040] A cutting component, disposed on the root-cutting component, is used to cut weeds entangled on the root-cutting component;

[0041] A power component, which is disposed on the root-cutting component, is capable of driving the shearing component to cut weeds.

[0042] The root-cutting component can be a blade, a hoe, or any device or tool capable of cutting the roots of weeds by shoveling into the soil. The shearing component can be a cutting blade, electric clippers, or other device or facility capable of cutting weeds. The power component can be an electric motor, or a device or facility that drives the cutting blade or electric clippers.

[0043] In use, the traction frame 610 is connected to the traction machinery (tractor, towing vehicle, etc.). The traction machinery then lowers the traction frame 610, causing it to lower the root-cutting components. Simultaneously, the traction machinery slowly advances, allowing several root-cutting components to enter between rows of seedlings. As the components descend, they follow the traction machinery forward, gradually shoveling into the soil. When the root-cutting components have penetrated to the required depth, such as 3-6 cm below the soil surface, effectively severing the roots of most weeds, the traction machinery stops driving the traction frame 610. The descent stops, and the traction machine continues to move forward. The root-cutting component then cuts the roots of the weeds between rows. As the root-cutting component moves forward, the weeds with cut roots will fall down and become entangled or hooked on the root-cutting component. At this point, the weeds will come into contact with the shearing component. The power component drives the shearing component to run, causing the weeds in contact with the shearing component to be cut off, thus breaking the weeds. In this way, as the root-cutting component moves forward, the weeds that are entangled or hooked on it are cut off, and after being cut off, the weeds slide off from both sides of the root-cutting component and leave the root-cutting component, thereby preventing the weeds from becoming entangled on the root-cutting component and accumulating.

[0044] By using the above method, when cutting weeds between rows of seedlings, weeds entangled on the root cutting component can be cut off, preventing weeds from tangling or hanging on it. This avoids the gradual accumulation of weeds, which increases in volume and weight and may scratch or damage the adjacent seedlings. It also avoids the increase in forward power of the traction machine due to the increased weight when weeds accumulate, reducing the energy consumption of the traction machine and lowering costs.

[0045] In a preferred embodiment, the root-cutting component includes a blade 110 and a housing 140 disposed on the rear side of the blade 110, the power component is disposed inside the housing 140, and the shearing component is disposed on the upper side of the housing 140.

[0046] As the traction frame 610 moves forward with the traction machinery, it drives the blade 110 on the root-cutting component forward. At the same time, the traction machinery drives the traction frame 610 to gradually descend, so that the blade 110 is inserted into the soil and moves forward together. During the forward movement of the blade 110, the roots of the weeds are cut off or dug out. That is to say, weeds with shallow roots will be dug out directly, while the roots of weeds with deep roots will be cut off.

[0047] The above methods can remove weeds between the rows of seedlings, thus preventing them from affecting the growth of the seedlings.

[0048] In a preferred embodiment, a triangular plate 130 is provided on the rear side of the blade 110 for guiding weeds to the cutting assembly.

[0049] When the blade 110 cuts the root of the weed, the weed will fall down. At this time, as the blade 110 continues to move forward, the weed can slide along the triangular plate 130, causing the weed to move towards the shearing component, so that it is cut off when it comes into contact with the shearing component, thereby avoiding entanglement on the root cutting component and the shearing component.

[0050] In a preferred embodiment, guide plates 120 extend rearward on both sides of the blade 110 for backfilling soil to the rear side of the blade 110.

[0051] After the blade 110 cuts the roots of the weeds, as the weeds fall over and the blade 110 continues to move forward, the weeds will cause the soil scooped up by the blade 110 to move to both sides of the blade 110, that is, to push the soil to both sides of the plant rows. This will cause the soil between the plant rows to be lower than the sides, forming a ditch. When the soil is pushed aside, as the blade 110 moves forward, the guide plate 120 on the rear side of the blade 110 can guide the soil on both sides to the rear side of the blade 110, so that the soil is backfilled in the area where the blade 110 has passed, thereby avoiding the formation of a ditch.

[0052] By using the above methods, it is possible to effectively avoid the formation of ditches during weeding, and to prevent the soil or roots of the seedlings from being exposed due to the presence of ditches. This would reduce the amount of soil around the roots and the sides of the seedlings, and prevent the seedlings from falling over during watering or in windy weather.

[0053] In a preferred embodiment, the shearing assembly includes a shearing tooth box 210 disposed in the housing 140 and open at the center of the front side, and a shearing tooth plate 220 slidably connected in the shearing tooth box. Both the shearing tooth box 210 and the shearing tooth plate 220 have a plurality of tooth blades 230 formed on their front sides. The power assembly drives the shearing tooth plate 220 to reciprocate along the height direction.

[0054] After the weeds are flattened, when the triangular plate 130 contacts the front side of the shearing box 210, the weeds will enter between several blades 230 on the front side of the shearing box 210. At this time, the power component drives the shearing plate 220 to move back and forth. The direction of movement of the shearing plate 220 is along the height direction of the shearing box 210. That is to say, when the shearing plate 220 moves back and forth, several blades 230 at the front end of the shearing plate 220 will cross with several blades 230 on the front side of the shearing box 210. During the crossing process, the weeds are cut, thus breaking the weeds. At this time, as the blade 110 continues to move forward, the outer shell 140 drives the shearing box 210 forward, passing through the broken weeds, thereby avoiding weed entanglement and effectively preventing weeds from tangling and gathering.

[0055] In a preferred embodiment, the power assembly includes a rotating wheel 310 rotatably connected to the root-cutting assembly. When the root-cutting assembly moves forward into the soil, the rotating wheel 310 rotates upon contact with the soil. A groove 320 is provided in the middle of the rotating wheel 310. Several arc-shaped protrusions 330 are distributed circumferentially along the axis of the rotating wheel 310 inside the groove 320. The lower end of the shear plate 220 passes through the outer shell 140 and contacts the arc-shaped protrusions 330.

[0056] When weeding, the root-cutting component is inserted into the soil, that is, when the blade 110 is inserted into the soil, it will drive the outer casing 140 closer to the soil surface. At this time, the rotating wheel 310 connected to the outer casing 140 will come into contact with the ground. As the root-cutting component moves forward with the traction frame 610, the rotating wheel 310 will move on the ground and roll. When the rotating wheel 310 rolls, several arc-shaped protrusions 330 in the groove 320 will pass through the lower end of the shearing plate 220 in sequence. Due to its own gravity, it will continue to slide downwards. When the arc-shaped protrusion 330 passes the shear plate 220, it will push the shear plate 220 upwards, causing the shear plate 220 to move upwards in the shear box 210. When the arc-shaped protrusion 330 leaves the lower end of the shear plate 220, the lower end of the shear plate 220 falls into the groove 320. In this way, the shear plate 220 slides back and forth in the vertical direction, so that the shear plate 220 and the shear box 210 cooperate to complete the process of cutting weeds.

[0057] In this way, the reciprocating motion of the shear plate 220 can be driven without the use of an additional power source, such as a motor, cylinder, or device and facility for driving the reciprocating motion of the shear plate 220, thereby reducing energy consumption and manufacturing costs.

[0058] In a preferred embodiment, a spring is provided between the upper end of the shear plate 220 and the inner top of the shear box 210. In the initial state, the spring is in its natural state, and the lower end of the shear plate 220 is in contact with the groove 320. When the rotating wheel 310 rotates, the arc-shaped protrusion 330 contacts the lower end of the shear plate 220 from below and pushes the shear plate 220 upward. During this process, the shear plate 220 compresses the spring, causing the spring to store force. When the arc-shaped protrusion 330 leaves the lower end of the shear plate 220, the spring pushes the shear plate 220 downward, providing a downward reset thrust for the shear plate 220.

[0059] By means of the above method, the driving force of the reciprocating movement of the shearing plate 220 during use can be increased, and the shearing force of the blade 230 on weeds can be increased when the shearing plate 220 and the shearing box 210 are in contact, thereby improving the ability to cut weeds.

[0060] In a preferred embodiment, a cleaning section is provided at the rear end of the housing 140, which can contact the rotating wheel 310 for cleaning the soil on the rotating wheel 310.

[0061] As the wheel 310 rolls across the ground, the soil adhering to its surface and in the grooves 320 is removed upon contact with the cleaning section. Figure 4 and Figure 6 As shown, the cleaning section includes a hinged plate 410 and a brush 420. The hinged plate 410 is detachably connected to the rear end of the housing 140 and can be connected by a buckle or bolts. After connection, the brush 420 is located inside the housing 140 and contacts the rotating wheel 310. When the rotating wheel 310 rolls, the soil attached to its surface and the groove 320 will be cleaned off by the brush 420, so as to prevent the soil from clogging the groove 320 and affecting the contact between the lower end of the shear plate 220 and the arc protrusion 330.

[0062] In the traditional method, the height of the traction frame 610 is controlled by the traction machinery. The lifting stroke of the traction machinery determines the lifting range of the traction frame 610, and the depth to which the root-breaking component is driven into the soil by the traction frame 610 is also matched accordingly. This can lead to a situation where the root-breaking component is not driven into the soil deeply enough. Therefore, in a preferred embodiment, an adjustment component is also included. The adjustment component is set on the shearing component, and the adjustment component can drive the shearing component to change its height, thereby changing the depth to which the root-breaking component is driven into the soil.

[0063] The adjusting component can be an electric telescopic rod, a cylinder, or other device or facility that can adjust its length. When in use, the adjusting component can further drive the root-cutting component to rise and fall, increasing the range and depth of the root-cutting component into the soil. When weeding weeds with deep roots, it can ensure that the roots are cut off or even dug out.

[0064] Specifically, an embodiment of the adjustment component in the above process is provided.

[0065] The adjustment assembly includes a sleeve 510 detachably connected to the traction frame 610, and a square tube 520 that slides and can be locked inside the sleeve 510. The shearing assembly is disposed at the lower end of the square tube 520.

[0066] The sleeve 510 is connected to the traction frame 610 via connectors such as bolts and buckles. The square tube 520 can slide in the sleeve 510 and can be fixed in position by buckles or tightening bolts. The shearing box 210 is detachably connected to the lower end of the square tube 520. When the square tube 520 slides in the sleeve 510, it can drive the shearing box 210, the outer shell 140 and the blade 110 to change the distance between them and the traction frame 610, thereby adjusting the depth to which the blade 110 can dig into the soil.

[0067] The above embodiments merely illustrate several implementation methods of this application, and while the descriptions are relatively specific and detailed, they should not be construed as limiting the scope of the patent application. It should be noted that those skilled in the art can make various modifications and improvements without departing from the concept of this application, and these all fall within the protection scope of this application. Therefore, the protection scope of this patent application should be determined by the appended claims.
