Description

Technical Field

[0001] This utility model relates to the field of walnut cultivation, and in particular to a weeding device for walnut cultivation. Background Technology

[0002] Walnuts are the fruit of a deciduous tree of the Juglandaceae family. They are covered with a hard outer shell and contain a kernel rich in unsaturated fatty acids, high-quality protein, and vitamin E. They can be eaten raw, roasted, or pressed for oil. Because of their high nutritional density, they are known as the "longevity fruit." The tree also has timber value and symbolizes wisdom and health in culture. Walnuts are a natural delicacy that combines nutritional, economic, and cultural significance.

[0003] Because weeds easily compete with walnuts for water and nutrients during their growth, it is often necessary to remove weeds from the soil before planting to ensure that walnuts can grow smoothly.

[0004] Currently, existing weeding devices often use a relatively movable cutter with a V-shaped groove at the front end to cut weeds. However, in actual use, although the V-shaped groove can gather the weeds on the inside of the cutter, when the cutter moves relative to the weeds, the contact surface between the cutter and the weeds is inclined, which also generates a pushing force on the sidewalls of the weeds away from the cutter. Therefore, after the cutter has been used for a period of time and its sharpness has decreased, the cutting effect is easily weakened. To address this problem, a weeding device for walnut planting is proposed. Utility Model Content

[0005] To overcome the above shortcomings, this utility model provides a walnut planting weeding device, which aims to improve the problem in the prior art where weeds are easily pushed out of the cutting area by the inclined surface of the cutter during the cutting process, thus affecting the cutting effect.

[0006] To achieve the above objectives, the present invention adopts the following technical solution: a walnut planting weeding device, comprising a frame, a support bar fixedly connected to the lower surface of the frame, a weed cutting mechanism provided on the inner side of the support bar, a support wheel provided on the lower surface of the frame near the front, a connecting bar fixedly connected to the lower surface of the frame near the right side, a rotating shaft rotatably connected to the inner wall of the connecting bar, and a roller fixedly connected to the outer wall of the rotating shaft;

[0007] The weed cutting mechanism includes a weed gathering component and a cutting component;

[0008] The grass-gathering component includes a grass-gathering board, the front side of which has a V-shaped groove, and the inner wall of the grass-gathering board behind the V-shaped groove has an anti-movement groove.

[0009] As a further description of the above technical solution:

[0010] The cutting assembly includes a sliding rod that is slidably connected to the upper surface of the grass-gathering board. A cutter is fixedly connected to the outer wall of the sliding rod. A sliding plate is slidably connected to the upper surface of the grass-gathering board behind the cutter. A contact groove is formed on the lower surface of the sliding plate near the front. An inclined groove is formed on the inner wall of the sliding plate above the contact groove. A control strip is fixedly connected to the upper surface of the sliding rod. The upper part of the control strip is located inside the inclined groove. A protrusion is fixedly connected to the outer wall of the rotating shaft. A reset assembly is jointly provided inside the sliding plate and the support strip.

[0011] As a further description of the above technical solution:

[0012] The reset assembly includes a movable groove, which is located on the side of the support bar near the sliding plate. A sliding block is slidably connected to the inner wall of the movable groove. The outer wall of the sliding block is fixedly connected to the outer wall of the sliding plate. The front end of the sliding block is elastically connected to the inner wall of the movable groove by a spring.

[0013] As a further description of the above technical solution:

[0014] The outer wall of the frame is rotatably connected to a push rod, which is U-shaped.

[0015] As a further description of the above technical solution:

[0016] The cutter is arc-shaped, and adjacent cutters are positioned at different locations in the vertical direction.

[0017] As a further description of the above technical solution:

[0018] The opening of the V-shaped groove on the side closer to the anti-slip groove is smaller than the opening farther away from the anti-slip groove.

[0019] As a further description of the above technical solution:

[0020] The number of anti-slip grooves is the same as the number of V-shaped grooves, and the anti-slip grooves correspond one-to-one with the V-shaped grooves.

[0021] As a further description of the above technical solution:

[0022] The thickness of the contact groove is the same as the thickness of the sliding rod, and the lower surface of the contact groove is in contact with the upper surface of the sliding rod.

[0023] This utility model has the following beneficial effects:

[0024] 1. In this utility model, by moving the cutter in the left and right directions and by setting the shape of the cutter, weeds are ensured to be gathered on the inside of the cutter after they come into contact with it. This ensures that when two adjacent cutters come into contact with each other, the weeds can be cut without being pushed outward, thus achieving the effect of cutting the weeds.

[0025] 2. In this utility model, by setting up the V-shaped groove and the anti-movement groove, weeds can be better controlled by the inclined surface of the V-shaped groove to enter the V-shaped groove. When the weeds enter the V-shaped groove, the displacement of the weeds in the left and right directions can be restored. At this time, the opening that the weeds need to pass through to pass through the V-shaped groove is small, so as to achieve the effect of ensuring that the weeds are not easily moved out of the area to be cut.

[0036] The technical solutions of the present utility model will be clearly and completely described below with reference to the accompanying drawings of the embodiments. Obviously, the described embodiments are only some embodiments of the present utility model, and not all embodiments. Based on the embodiments of the present utility model, all other embodiments obtained by those of ordinary skill in the art without creative effort are within the protection scope of the present utility model.

[0037] Reference Figures 1-3 The present invention provides an embodiment of a walnut planting weeding device, comprising a frame 1, which is the main frame of the walnut planting weeding device. A push rod is rotatably connected to the outer wall of the frame 1. The push rod ensures that the staff can push the device to move it. The push rod is U-shaped. A support bar 2 is fixedly connected to the lower surface of the frame 1. The support bar 2 is L-shaped and is located on the front and rear sides of the frame 1.

[0038] Reference Figure 3 , Figure 4 and Figure 4 The inner side of the support bar 2 is provided with a weed cutting mechanism 3. The weed cutting mechanism 3 includes a grass gathering component 31 and a cutting component 32. The grass gathering component 31 includes a grass gathering plate 311, which is used to gather weeds. A V-shaped groove 312 is provided on the front side of the grass gathering plate 311. The grass gathering plate 311 can move backward along its inclined surface by setting the V-shaped groove 312. An anti-movement groove 313 is provided on the inner wall of the grass gathering plate 311 behind the V-shaped groove 312. The anti-movement groove 313 makes it difficult for weeds to leave the area to be cut. The opening of the V-shaped groove 312 near the anti-movement groove 313 is smaller than the opening away from the anti-movement groove 313. The number of anti-movement grooves 313 is the same as the number of V-shaped grooves 312, and the anti-movement grooves 313 and V-shaped grooves 312 correspond one-to-one. When weeds pass through the V-shaped groove 312, they can enter the anti-movement groove 313.

[0039] Reference Figure 2 , Figure 3 and Figure 6The cutting assembly 32 includes a sliding rod 321, which is slidably connected to the upper surface of the grass gathering board 311. A cutter 322 is fixedly connected to the outer wall of the sliding rod 321. The cutter 322 is arc-shaped, and two adjacent cutters 322 are in different positions in the vertical direction. By setting the shape of the cutter 322, when two adjacent cutters 322 come close to each other, they can gather the weeds together without pushing them out.

[0040] Reference Figures 6-8 A sliding plate 323 is slidably connected to the upper surface of the grass-gathering board 311 behind the cutter 322. The sliding plate 323 slides left and right relative to the grass-gathering board 311. A contact groove 324 is provided on the lower surface of the sliding plate 323 near the front. The thickness of the contact groove 324 is the same as the thickness of the sliding rod 321. The lower surface of the contact groove 324 contacts the upper surface of the sliding rod 321. An inclined groove 325 is provided on the inner wall of the sliding plate 323 above the contact groove 324. The inclined groove 325 ensures that when the sliding plate 323 moves back and forth, the left and right position of the inclined groove 325, which is in the same position in the front and back direction, changes. A control strip 326 is fixedly connected to the upper surface of the sliding rod 321. The upper part of the control strip 326 is set inside the inclined groove 325. A protrusion 327 is fixedly connected to the outer wall of the rotating shaft 5.

[0041] Reference Figure 1 , Figure 3 and Figure 5 The interior of the sliding plate 323 and the interior of the support bar 2 are jointly provided with a reset component 34. The reset component 34 includes a moving groove 341, which is opened on the side of the support bar 2 near the sliding plate 323. A sliding block 342 is slidably connected to the inner wall of the moving groove 341. The sliding block 342 moves back and forth relative to the moving groove 341. The outer wall of the sliding block 342 is fixedly connected to the outer wall of the sliding plate 323. The front end of the sliding block 342 is elastically connected to the inner wall of the moving groove 341 by a spring 343. One end of the spring 343 is fixedly connected to the front end of the sliding block 342, and the other end of the spring 343 is fixedly connected to the inner wall of the moving groove 341.

[0042] Reference Figure 1 and Figure 2 Support wheels 7 are provided on the lower surface of the frame 1 near the front side. A connecting strip 4 is fixedly connected to the lower surface of the frame 1 near the right side. A rotating shaft 5 is rotatably connected to the inner wall of the connecting strip 4. A roller 6 is fixedly connected to the outer wall of the rotating shaft 5. The lower end of the roller 6 is in contact with the ground.

[0043] Working principle: When in use, the staff pushes the equipment into the land where weeding is needed and pushes the equipment through the push rod on the outside of the frame 1.

[0044] As the frame 1 moves forward after being pushed, the weeds can enter the anti-movement groove 313 along the inclined surface of the V-shaped groove 312 after contacting the inclined surface of the V-shaped groove 312.

[0045] Since the opening at the rear end of the V-groove 312 is smaller than the opening at the front end, even if the weeds are subjected to a forward external force, they are more likely to come into contact with the front surface of the anti-movement groove 313 and have difficulty passing through the V-groove 312.

[0046] At the same time, after the equipment is pushed, the roller 6 rotates due to contact with the ground, thereby driving the rotating shaft 5 to rotate.

[0047] After the rotating shaft 5 rotates, it drives the protrusion 327 to rotate synchronously. When the protrusion of the protrusion 327 rotates to a position close to the front, it pushes the sliding plate 323 to move forward. During the forward movement of the sliding plate 323, the inclined surface of the inclined groove 325 pushes the control bar 326, thereby causing the control bar 326 to drive the sliding rod 321 and the cutter 322 to move towards the center of the anti-slip groove 313.

[0048] Because the cutter 322 is curved, as the cutter 322 moves toward the center of the anti-movement groove 313, it can only gather the weeds toward the center of the anti-movement groove 313, but cannot push the weeds out.

[0049] When two adjacent cutters 322 come into contact, the weeds are cut off by the combined cutting action of the two cutters 322.

[0050] When the protrusion 327 rotates away from the sliding plate 323, the sliding block 342 is driven by the elastic force of the spring 343 to reset the sliding plate 323. During the reset process, the inclined groove 325 pushes the control bar 326 through the inclined surface, so that the control bar 326 is reset, thereby ensuring that the equipment can collect and cut weeds multiple times and ensure the cutting effect.

[0051] Finally, it should be noted that the above description is only a preferred embodiment of the present utility model and is not intended to limit the present utility model. Although the present utility model has been described in detail with reference to the foregoing embodiments, those skilled in the art can still modify the technical solutions described in the foregoing embodiments or make equivalent substitutions for some of the technical features. Any modifications, equivalent substitutions, improvements, etc., made within the spirit and principles of the present utility model should be included within the protection scope of the present utility model.
