Abstract
Description
Technical Field
[0001] This utility model belongs to the field of agricultural machinery technology, specifically relating to a wide-range adjustable tillage weeding device. Background Technology
[0002] In grain cultivation, mechanized planting is used to create evenly spaced rows. However, during the growth of seedlings from grain seeds, weeds growing between the rows can seriously threaten their growth. They not only block sunlight but also compete with the seedlings for water and nutrients, requiring timely removal. Moreover, different types of grains have different row spacings after planting, meaning the row widths vary. Current weeding tools are of a single type and have a fixed width. When weeding, they can complete the weeding work when the row spacing matches the width. However, they cannot weed when the row spacing is too small or too large. When the row spacing is too small, the tool may damage the seedlings, while when the row spacing is too large, a single movement cannot cover the width of the weed distribution.
[0003] For example, prior art with publication number CN220776417U discloses a weeding and tilling 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 in farmland, the width of the weeding mechanism is fixed and cannot be changed. It cannot meet the needs when the row spacing is different, unless a different size weeding mechanism is used. However, that would require more cost and temporary replacement, which would not only delay the weeding process but also cause the user to expend a lot of physical energy. Summary of the Invention
[0004] Based on this, this application provides a wide-width adjustable weeding device for cultivation, to solve the technical problem that the size of existing weeding tools is fixed and cannot be used between multiple rows of seedlings with different row spacing.
[0005] The technical solution to the above-mentioned technical problems in this application is as follows:
[0006] A wide-range adjustable tillage weeding device includes:
[0007] A towing frame is used to connect to traction equipment;
[0008] A weed-shoveling assembly, several weed-shoveling assemblies are set on the traction frame, used to shovel into the soil to cut the roots of weeds;
[0009] The weed-shoveling assembly has extension components on both sides, which can change the width range of the weed-shoveling assembly in lateral weeding.
[0010] A support component is disposed on the weeding component and is used to drive the extension component to adjust the width of the side of the weeding component.
[0011] Preferably, the grass-shoveling assembly includes a shovel head and a suspension arm disposed at the rear end of the shovel head and provided with a reinforcing plate. The suspension arm is disposed on the traction frame, and the extension assembly is disposed on both sides of the shovel head.
[0012] Preferably, the front end of the reinforcing plate is provided with a guide cone for pushing away the soil, and the support component is disposed on the reinforcing plate.
[0013] Preferably, the extension component includes a side blade with a rotating column, and the ends of the two side blades are rotatably connected to both sides of the shovel head via connecting ears. The support component is connected to the rotating column and can drive the side blades to rotate on the connecting ears.
[0014] Preferably, the support assembly includes a bolt connected to the reinforcing plate and a movable plate connected to the bolt, the movable plate being rotatably connected to a rotating arm, the end of the rotating arm being rotatably connected to a rotating column.
[0015] Preferably, the reinforcing plate has an elongated hole, in which the bolt can slide, and when the nut is tightened, the movable plate is clamped to the reinforcing plate for position fixation.
[0016] Preferably, a torsion spring is provided at the rotatable connection between the connecting ear and the side blade, and the torsion spring drives the side blade to rotate toward the reinforcing plate.
[0017] Preferably, it also includes an adjustment component, which is disposed on the weeding component and detachably connected to the traction frame. The adjustment component can drive the weeding component to adjust the depth of the weeding component into the soil.
[0018] Preferably, the adjustment 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 grass-shoveling assembly disposed at the lower end of the square tube.
[0019] Compared with the prior art, this application has at least the following advantages:
[0020] This application provides a wide-width adjustable weeding device for cultivation. When weeding between rows of seedlings, in the initial state, the support component drives two extension components to rotate and retract towards the weeding component. That is, the extension components retract from both sides to the width range of the weeding component. When the traction device, such as a tractor or towing vehicle, lowers the traction frame, the traction frame lowers the weeding component and the extension components, causing the weeding component to shovel into the soil. At this time, as the traction device moves forward, the width of the weeding component between the rows is its own width. Therefore, by the support component driving the extension components to rotate and open on the side of the weeding component, that is, the extension components rotate out to both sides of the weeding component, extending the weeding range formed by the two together. This allows for adjustment according to different row spacing sizes. When the traction device moves forward, the weeds between the rows are removed. When weeding between rows of seedlings, it can adaptively adjust according to the width of the row spacing to ensure that all weeds between rows are removed. Compared with traditional weeding tools that have limited width and cannot be adjusted, it is suitable for more scenarios and can improve the weed removal effect and range.

[0033] Please refer to Figure 1 and Figure 8 In one specific embodiment of this application,
[0034] A wide-range adjustable tillage weeding device includes:
[0035] The draw frame 510 is used to connect to the traction equipment;
[0036] A weed-shoveling assembly, several weed-shoveling assemblies are set on the traction frame 510, used to shovel into the soil to cut the roots of weeds;
[0037] The weed-shoveling assembly has extension components on both sides, which can change the width range of the weed-shoveling assembly in lateral weeding.
[0038] A support component is disposed on the weeding component and is used to drive the extension component to adjust the width of the side of the weeding component.
[0039] The weeding component and the extension component can be weeding tools, hoes, shovels, or devices and facilities capable of removing weeds. The support component can be a telescopic rod (such as a cylinder or electric push rod), or a device or facility capable of moving the extension component.
[0040] When weeding between rows of seedlings, in the initial state, the support component drives the two extension components to rotate and retract towards the weeding component. That is, the extension components retract from both sides to the width range of the weeding component. When the traction device, such as a tractor or towing vehicle, lowers the traction frame 510, the traction frame 510 lowers the weeding component and the extension components, causing the weeding component to shovel into the soil. At this time, as the traction device moves forward, the width of the weeding component between the rows is its own width. Therefore, the support component drives the extension components to rotate and open on the side of the weeding component, that is, the extension components rotate out to both sides of the weeding component, extending the weeding range formed by the two together. This allows for adjustment according to the different row spacing sizes. Under the traction of the traction device, the weeds in the row spacing are removed.
[0041] The above method allows for adaptive adjustments based on the row spacing when weeding between multiple rows of seedlings, ensuring that all weeds between rows can be removed. Compared to traditional methods where weeding tools have limited width and cannot be adjusted, this method is suitable for more scenarios and can improve the weed removal effect and range.
[0042] In a preferred embodiment, the grass-shoveling assembly includes a shovel head 110 and a suspension arm 120 disposed at the rear end of the shovel head 110 and provided with a reinforcing plate 130. The suspension arm 120 is disposed on the traction frame 510, and the extension assembly is disposed on both sides of the shovel head 110.
[0043] The suspension arm 120 is connected to the traction frame 510 in a detachable manner using bolts or latches, facilitating replacement and maintenance. When the traction device moves the traction frame 510 forward, it first lowers the traction frame 510, causing the shovel head 110 to shovel soil below the soil surface. During the movement, the shovel head 110 cuts the roots of the weeds, thus removing them. The extension component rotates on both sides of the shovel head 110. Initially, the extension component rotates closer to the suspension arm 120, and at this time, the extension component is within the width range of the shovel head 110. When adjustment is needed, the support component drives the extension component to rotate outward on the side of the shovel head 110, that is, to rotate away from the suspension arm 130. Thus, when the extension component is rotated open, the weed-shoveling range on the side of the shovel head 110 is extended.
[0044] In a preferred embodiment, the front end of the reinforcing plate 130 is provided with a guide cone 140 for pushing away the soil, and the support component is disposed on the reinforcing plate 130.
[0045] The reinforcing plate 130 can increase the strength of the suspension arm 120 in the vertical direction and improve the resistance to deformation of the suspension arm 120 in the direction of following the traction equipment. At the same time, when the shovel head 110 removes weeds as the suspension arm 120 moves forward, it will scoop up a small amount of soil because it is below the soil surface. At this time, the guide cone 140 can be used to block and guide the soil in the forward direction, so that the soil flows to both sides after encountering the guide cone 140, preventing the soil from accumulating on the suspension arm 120. It can also push away the weeds when the roots are cut by the shovel head 110 and the weeds fall down, preventing the weeds from getting tangled on the suspension arm 120.
[0046] In a preferred embodiment, the extension component includes a side blade 210 with a rotating post 220. The ends of the two side blades 210 are rotatably connected to both sides of the shovel head 110 via connecting ears 150. The support component connected to the rotating post 220 can drive the side blades 210 to rotate on the connecting ears 150.
[0047] During application, the end of the side blade 210 near the shovel head 110 is rotatably connected to the connecting ear 150, which is located on the shovel head 110. The side blade 210 can rotate around the rotatable connection between the side blade 210 and the connecting ear 150. The rotating column 220 connected by the support component can rotate the side blade 210 when the support component moves the end of the side blade 210 away from the shovel head 110 via the rotating column 220. In other words, when the support component moves the rotating column 220 closer to the suspension arm 120, it can move the side blade 210 closer to the suspension arm 120, so that the two side blades 210 on both sides of the shovel head 110 can close. At this time, the weeding width formed by the side blade 210 and the shovel head 110 together decreases. Conversely, when the support component moves the rotating column 220 away from the suspension arm 120, the side blade 210 unfolds, increasing the weeding width formed by the side blade 210 and the shovel head 110 together. In this way, the width of the weed cutter can be adaptively adjusted to meet the needs of weeding with different row spacing.
[0048] In a preferred embodiment, the support assembly includes a bolt 310 connected to the reinforcing plate 130 and a movable plate 320 connected to the bolt 310. The movable plate 320 is rotatably connected to a rotating arm 330, and the end of the rotating arm 330 is rotatably connected to a rotating column 220.
[0049] Bolt 310 can be connected to different positions on reinforcing plate 130. When in use, bolt 310 is installed (the installation method can be to open multiple threaded holes on reinforcing plate 130 and move bolt 310 through the connection position of different threaded holes) on the side of reinforcing plate 130 near shovel head 110. This allows moving plate 320 to pull the end of rotating arm 330 connected to rotating column 220 closer to suspension arm 120, thereby causing rotating column 220 to drive side blade 210 to rotate towards suspension arm 120 to complete the closure. Conversely, when bolt 310 is installed on the side of reinforcing plate 130 away from shovel head 110, when moving plate 320 moves, rotating arm 330 will rotate forward under the restriction of rotating column 220. At this time, the end of rotating arm 330 drives rotating column 220 to move away from suspension arm 120, thereby causing side blade 210 to rotate and unfold, increasing the shoveling range.
[0050] In a preferred embodiment, a torsion spring is provided at the rotatable connection between the connecting ear 150 and the side blade 210, and the torsion spring drives the side blade 210 to rotate toward the reinforcing plate 130.
[0051] Driven by the torsion spring, the side blade 210 maintains a rotational tendency toward the suspension arm 120. Thus, when the moving plate 320 moves, the rotating column 220 at the other end of the side blade 210 can drive the rotating arm 330 to always maintain a rotational tendency toward the suspension arm 120. Therefore, when the moving plate 320 moves along the direction of the reinforcing plate 130, it drives the rotating arm 330 to rotate on the moving plate 320. That is, when the bolt 310 drives the moving plate 320 to move toward the shovel head 110, the rotating arm 330 rotates toward the suspension arm 120; conversely, the rotating arm 330 rotates away from the suspension arm 120, realizing the opening and closing process of the side blade 210.
[0052] In a preferred embodiment, the reinforcing plate 130 has an elongated hole 160, the bolt 310 can slide in the elongated hole 160, and when the nut is tightened, the movable plate 320 is clamped to the reinforcing plate 130 for position fixation.
[0053] Bolt 310 is inserted into elongated hole 160. When bolt 310 slides along the length of elongated hole 160, it drives two movable plates 320 to move. The two movable plates 320 are located on both sides of reinforcing plate 130. After bolt 310 is fixed in its moved position, the nut on bolt 310 can be tightened, pressing one of the movable plates 320 against it. The two movable plates 320 clamp the reinforcing plate 130 to increase friction and thus fix the position. In other words, when bolt 310 moves towards the shovel head 110 in elongated hole 160, the movable plate 320 drives the rotating arm 330 to rotate towards the suspension arm 120, closing the side blade 210, and vice versa. This method allows for convenient repositioning and fixing of bolt 310, facilitating operation.
[0054] In the traditional method, the height of the traction frame 510 is controlled by the traction machinery. The lifting stroke of the traction machinery determines the lifting range of the traction frame 510, and the depth of the weeding component driven by the traction frame 510 into the soil is also matched accordingly. There is a situation where the weeding component does not penetrate the soil deeply enough. Therefore, in a preferred embodiment, an adjustment component is also included. The adjustment component is set on the weeding component and is detachably connected to the traction frame 510. The adjustment component can drive the weeding component to adjust the depth of penetration into the soil.
[0055] The adjustment component can be an electric telescopic rod, a cylinder, or other device or facility that can adjust its length. When in use, the adjustment component can further drive the weeding component to rise and fall, increasing the range and depth of the weeding component. This can also increase the depth into the soil, ensuring that the roots of deep-rooted weeds are cut or even dug out during weeding.
[0056] In a preferred embodiment, the adjustment assembly includes a sleeve 410 detachably connected to the traction frame 510, and a square tube 420 that slides within the sleeve 410 and can be locked in place, with the grass-shoveling assembly disposed at the lower end of the square tube 420.
[0057] The sleeve 410 is connected to the traction frame 510 by connectors such as bolts and locks. The square tube 420 can slide in the sleeve 410 and can be fixed in position by the lock or tightening bolts. The suspension arm 120 is detachably connected to the lower end of the square tube 420. When the square tube 420 slides in the sleeve 410, it can drive the suspension arm 120 to change the distance between it and the traction frame 510, thereby adjusting the depth to which the shovel head 110 can dig into the soil.
[0058] 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.
