Description

Technical Field

[0001] This utility model relates to the field of agricultural implements technology, and in particular to a weeding device for ridge-grown crops. Background Technology

[0002] Ridge cultivation is a common agricultural practice that involves piling soil into raised ridges (ridge platforms) and planting crops on them to improve soil aeration, drainage, and ground temperature. It is suitable for crops such as potatoes, corn, and tobacco. Ridge cultivation typically consists of ridge platforms, furrows, and ridge sides. However, the complex structure also makes it easy for weeds to grow in multiple places, including the top of the ridges, the ridge sides, and the furrows, which can affect crop growth.

[0003] In related technologies, farmers often use hand-push small weeders for weeding in small farmlands or family farms. These devices are usually pushed by manpower and rely on rotating blades or hoes to cut or remove weeds. They are characterized by low cost and flexible operation, making them suitable for small-scale planting scenarios.

[0004] However, the blades of existing small weeders are usually designed to be horizontal and fixed, which can only work on the bottom of the furrows and cannot effectively clear weeds on the top of the ridges and the slopes of the ridges. This results in incomplete weeding and still requires manual weeding, which increases labor intensity and production costs. Utility Model Content

[0005] This utility model provides a weeding device for ridge crops, which solves the technical problem that existing small weeders, due to structural limitations, fail to thoroughly remove weeds from ridge crops, thus increasing labor intensity and production costs. The technical solution is as follows: This utility model provides a weeding device for ridge crops, including: a main frame, wheels, and a mowing assembly. The walking wheels are located at the front end of the main frame, and a push handle is located at the top rear end of the main frame. The mowing assembly includes a connecting frame, a flat blade, and a tillage rake. The connecting frame is located at the bottom rear end of the main frame and is connected to the main frame at one end. The flat blade and the tillage rake are detachably connected to the other end of the connecting frame. The cutting edge of the flat blade faces the walking wheels, and the tillage rake is longitudinally positioned above the flat blade and its orientation is adjustable relative to the traveling direction of the walking wheels.

[0006] Optionally, the connecting frame includes two vertical support rods and a mounting beam. The tops of the two vertical support rods are connected to the main frame, and the mounting beam is laterally connected to the bottoms of the two vertical support rods. The mounting beam has multiple fixing parts evenly distributed along its length, and the flat blade and the tillage harrow are connected to at least one of the multiple fixing parts.

[0007] Optionally, the fixing part is a first fixing hole, and the flat blade is provided with a second fixing hole that matches the first fixing hole, and is bolted to the mounting beam through the second fixing hole and the first fixing hole.

[0008] Optionally, a plurality of second fixing holes are provided and are spaced apart along the extension direction of the flat blade.

[0009] Optionally, the tillage harrow includes harrow blades and a connecting part, the connecting part being provided with a third fixing hole that matches the first fixing hole, and being bolted to the mounting beam through the third fixing hole and the first fixing hole.

[0010] Optionally, the tillage harrow includes harrow teeth, which are integrally formed and connected above the flat blade.

[0011] Optionally, the vertical support rod is an electric telescopic rod, and the main frame is equipped with an electric control box that is electrically connected to the electric telescopic rod, and the push handle is equipped with a controller that is electrically connected to the electric control box.

[0012] Optionally, a rotating motor is provided at the bottom rear end of the main frame. The rotating motor is electrically connected to the electrical control box. The top of the vertical support rod is connected to the rotating end of the rotating motor. The rotating shaft of the rotating motor is parallel to the mounting beam.

[0013] Optionally, the main frame includes a base frame and a vertical beam. The base frame is arranged horizontally, the traveling wheel is disposed at one end of the base frame, the vertical beam is longitudinally connected to the top of the other end of the base frame, the push handle is disposed at the top of the vertical beam and extends away from the traveling wheel, and one end of the connecting frame is connected to the bottom of the other end of the base frame.

[0014] Optionally, a reinforcing bar is provided between the vertical beam and the base frame.

[0015] The beneficial effects of the technical solution provided by this utility model embodiment include at least the following: When using this weeding device for ridge crops, the user can hold the handle on the side where it is located, lift and push the entire main frame, guided by the wheels, to move it within the furrow between two ridges. During movement, the flat blades located below the connecting frame are parallel to the ground and scrape away the topsoil, cutting the grass. This effectively cuts and removes weeds within the furrow area. In the weeding assembly connected to the bottom of the connecting frame, a longitudinally positioned tillage harrow is located above the flat blades. Before weeding, the orientation of the tillage harrow is adjusted according to the angle of the ridge sides on both sides of the furrow, ensuring that the harrow blades intersect the slope of the ridge side. While moving along the ridge, the flat blades remove weeds in the furrows, and the above-mounted rakes simultaneously insert shallowly into the soil on the ridge side slope, thus bringing out the weeds on the ridge side as well. This greatly reduces the amount of manual weeding required afterward and solves the technical problem of existing small weeders not being able to completely remove weeds from ridge crops due to structural limitations, which increases labor intensity and production costs.

Detailed Implementation To make the objectives, technical solutions, and advantages of this utility model clearer, the embodiments of this utility model will be described in further detail below with reference to the accompanying drawings.

[0019] Figure 1 This is a three-dimensional structural schematic diagram of the weeding device for ridge crops provided in this embodiment of the utility model; Figure 2 This is a partial structural schematic diagram of the lawn mowing component provided in an embodiment of the present utility model; Figure 3 This is a partial structural diagram of the connection between the connecting frame and the flat blade provided in this embodiment of the utility model; Figure 4 This is a schematic diagram of the structure of the flat blade provided in this embodiment of the utility model; Figure 5 This is a schematic diagram of the structure of a tillage harrow provided in an embodiment of this utility model; Figure 6 This is a schematic diagram of another tillage harrow structure provided in an embodiment of this utility model. (See diagram below.) Figures 1 to 6 As shown, this utility model embodiment provides a weeding device for ridge crops, including a main frame 1, a walking wheel 2, and a mowing component 3.

[0020] The walking wheels 2 are located at the front end of the main frame 1, and a push handle 4 is located at the top rear end of the main frame 1. The mowing assembly 3 includes a connecting frame 31, a flat blade 32, and a tillage harrow 33. The connecting frame 31 is located at the bottom rear end of the main frame 1 and is connected to the main frame 1 at one end. The flat blade 32 and the tillage harrow 33 are detachably connected to the other end of the connecting frame 31, with the cutting edge of the flat blade 32 facing the walking wheels 2. The tillage harrow 33 is longitudinally positioned above the flat blade 32, and its orientation is adjustable relative to the traveling direction of the walking wheels 2.

[0021] In this embodiment of the invention, when using the weeding device for ridge crops, the user can hold the push handle 4 on one side, lift and push the entire main frame 1, guided by the wheels 2, to move within the furrow between two ridges. During this movement, the flat blade 32 located below the connecting frame 31 is parallel to the ground and scrapes away the top layer of soil, thus cutting the grass and effectively removing weeds within the furrow area. In the weeding assembly 3 connected to the bottom of the connecting frame 31, a longitudinally positioned tillage harrow is also provided above the flat blade 32. Before weeding, the orientation of the tillage harrow 33 is adjusted according to the angle of the sides of the ridge, so that the direction of the harrow blade intersects with the slope of the ridge side. While the flat blade 32 is used to remove weeds in the furrows during the movement, the intermediate harrow 33 above it will simultaneously insert shallowly into the soil on the ridge side slope, thereby bringing out the weeds on the side of the ridge, greatly reducing the amount of manual weeding work afterwards. This can solve the technical problem that existing small weeders are limited by structure, resulting in incomplete weeding of ridge crops, which increases labor intensity and production costs.

[0022] Exemplary, in this embodiment of the invention, the main frame 1 has only one wheel 2 at its front end. This single-wheel structure provides the user with the freedom to tilt to both sides when pushing with the handle 4, after setting the approximate orientation of the tillage harrow 33 relative to the ridge slope. During pushing, the user can flexibly tilt the main frame 1 left and right, ensuring that the tillage harrow 33 on the flat blade 32 fully contacts the surface soil of the ridge slope, thus guaranteeing effective weed control.

[0023] Optionally, the connecting frame 31 includes two vertical support rods 311 and a mounting beam 312. The tops of the two vertical support rods 311 are connected to the main frame 1, and the mounting beam 312 is laterally connected to the bottoms of the two vertical support rods 311. Multiple fixing parts 3121 are evenly distributed along the length of the mounting beam 312. The flat blade 32 and the tillage harrow 33 are connected to at least one of the fixing parts 3121. Exemplarily, in this embodiment of the invention, the connecting frame 31 has an inverted U-shaped frame structure, supported by multiple points of connection through the two vertical support rods 311, which improves structural stability and mechanical strength. The mounting beam 312 at the bottom is provided with multiple fixing parts 3121 for connecting the flat blade 32 and the tillage harrow 33. Before weeding, the user can adjust the installation position of the flat blade 32 and the relative installation position and orientation angle of the tillage harrow 33 according to the actual weeding environment requirements to adapt to different soil conditions and improve adaptability.

[0024] Optionally, the fixing part 3121 is a first fixing hole, and the flat blade 32 is provided with a second fixing hole 321 that matches the first fixing hole. The flat blade 32 is bolted to the mounting beam 312 through the second fixing hole 321 and the first fixing hole. Exemplarily, in one possible implementation of this utility model, the fixing part 3121 is a through-hole structure, and the corresponding flat blade 32 is provided with a second fixing hole 321. During assembly, the two are bolted together using standard parts, resulting in a simple structure and convenient disassembly and adjustment.

[0025] Optionally, multiple second fixing holes 321 are provided and spaced apart along the extension direction of the flat blade 32. Further, in this embodiment of the invention, depending on the actual weeding environment requirements, the second fixing holes 321 at different positions on the flat blade 32 can be matched with the first fixing holes on the mounting beam 312 to achieve relative position adjustment of the flat blade 32 relative to the connecting frame 31. This allows the flat blade 32 to extend to the left and right sides relative to the connecting frame 31, adapting to the clearing of weeds in furrows of different widths, thus improving practicality.

[0026] Optionally, the tillage harrow 33 includes a harrow blade 331 and a connecting part 332. The connecting part 332 is provided with a third fixing hole 3321 that matches the first fixing hole, and is bolted to the mounting beam 312 through the third fixing hole 3321 and the first fixing hole. Exemplarily, in one open-view embodiment of this utility model, the tillage harrow 33 and the mounting beam 312 are also bolted together. By selecting different positions of the first fixing hole and using the third fixing hole 3321 on the connecting part 332 for connection, the harrow blade 331 can be positioned in different locations. By adjusting the orientation of the connecting part 332 before bolting, the orientation of the harrow blade 331's cutting edge can be adaptively adjusted. The structure is simple, and disassembly and adjustment are convenient.

[0027] Optionally, the tillage harrow 33 includes harrow teeth 333, which are integrally formed and connected above the flat blade 32. Exemplarily, in another possible implementation of this utility model, the tillage harrow 33 can also use a harrow tooth 333 structure integrally formed with the flat blade 32. During the relative adjustment of the relative position of the flat blade 32 and the connecting frame 31, the relative adjustment of the harrow tooth 333 position can be displayed. Furthermore, by prefabricating harrow teeth 333 with different orientations relative to the cutting edge of the flat blade 32, before weeding, a flat blade 32 with corresponding harrow teeth 333 can be selected to cooperate with the mounting beam 312, thereby achieving the orientation adjustment of the tillage harrow 33. This further improves adjustment and assembly efficiency.

[0028] Optionally, the vertical support rod 311 is an electric telescopic rod. An electrical control box 5, electrically connected to the electric telescopic rod, is mounted on the main frame 1, and a controller 51, electrically connected to the electrical control box 5, is mounted on the push handle 4. Exemplarily, in this embodiment of the invention, the user can adjust the rod using the controller held on the push handle 4. Upon receiving a control command from the electrical control box 5, the user can drive the vertical support rod 311 to extend and retract longitudinally, adjusting the relative distance between the flat blade 32 and the tillage harrow 33 and the surface of the raised bed to adapt to different raised bed heights and to overcome obstacles during weeding. This eliminates the need for the user to physically move and adjust the entire main frame 1, reducing the user's burden and improving weeding efficiency.

[0029] Optionally, a rotary motor 6 is provided at the bottom rear end of the main frame 1. The rotary motor 6 is electrically connected to the electrical control box 5. The top of the vertical support rod 311 is connected to the rotating end of the rotary motor 6, and the rotating shaft of the rotary motor 6 is parallel to the mounting beam 312. Exemplarily, in several embodiments of this utility model, by providing a rotary motor 6 at the bottom rear end of the main frame 1, its rotating end has a certain rotational stroke along the axial direction of the rotating shaft. This stroke can be adjusted by the controller 51 during user operation. Upon receiving a control command from the electrical control box 5, its rotating end can drive the vertical support rod 311, as well as the entire flat blade 32 and the tillage harrow 33, to rotate back and forth along the horizontal rotating shaft. When rotating forward, the flat blade 32 and the tillage harrow 33 embedded in the soil can be pushed upwards by the power to fully cut weeds and remove them from the soil. When the flat blade 32 and the tillage rake 33 are embedded too deeply into the soil, causing the movement to become stuck, they can be rotated backward and pushed upward to exit the soil layer in the opposite direction, so that the user can adjust and continue to move. The operation is carried out in an electronic way, so the user does not need to move and adjust the entire main frame 1, which saves time and effort and can further improve weeding efficiency.

[0030] Optionally, the main frame 1 includes a base frame 11 and a vertical beam 12. The base frame 11 is horizontally arranged, with wheels 2 located at one end of the base frame 11. The vertical beam 12 is longitudinally connected to the top of the other end of the base frame 11. A push handle 4 is located at the top of the vertical beam 12 and extends away from the wheels 2. One end of a connecting frame 31 is connected to the bottom of the other end of the base frame 11. Exemplarily, in this embodiment of the invention, the main frame 1 includes a horizontally placed base frame 11 with a certain distance from the ground. The base frame 11 has a certain extension length, and wheels 2 are located at one end of the base frame 11. The vertical beam 12 is longitudinally connected to the top of the other end of the base frame 11, and its entire structure is inclined away from the wheels 2. The push handle 4 is located at the top of the vertical beam 12 and extends away from the wheels 2. When the user holds the frame, the lawnmower assembly 3 is located at the bottom of the other end of the base frame 11, that is, the entire assembly is located in front of the user, leaving space for the user to stand and walk. When the user is not moving, the connecting frame 31 can also serve as a support structure between the user and the walking wheels 2, and contact the ground to ensure that the entire weeding device for ridge crops remains upright.

[0031] Optionally, a reinforcing rod 13 is provided between the vertical beam 12 and the base frame 11. Exemplarily, in this embodiment of the present invention, a U-shaped reinforcing rod 13 is provided between the vertical beam 12 and the base frame 11, with one end connected to the vertical beam 12 and the other end connected to the base frame 11. This can prevent all stress from concentrating at the connection between the base frame 11 and the vertical beam 12 during operation, thereby improving the overall mechanical strength and structural stability.
