Description

Weeding equipment for broad bean fields that prevents root damage Technical Field

[0001] This utility model relates to the field of agricultural machinery and equipment technology, specifically to a weeding device for broad bean fields that prevents root damage. Background Technology

[0002] In agricultural production, broad beans are an important food and cash crop, and weed control during cultivation is a crucial step in ensuring yield and quality. Manual weeding by hand remains one of the most common methods for weeding broad bean fields.

[0003] Existing handheld weeding tools are mostly simple shovels and hoes, which come into direct contact with the soil, easily damaging broad bean roots and affecting plant growth. While some designs have attempted improvements, they suffer from complex structures, inflexible operation, and poor grip comfort, failing to effectively adapt to the complex planting environment of broad bean fields. Furthermore, in confined planting spaces, traditional handheld tools struggle to precisely control the weeding area, easily damaging broad bean plants. Therefore, there is an urgent need for a handheld weeding device that is comfortable to hold, easy to operate, and capable of accurately removing weeds without damaging broad bean roots, to solve the problems of existing technologies and improve the quality and efficiency of broad bean cultivation. Summary of the Invention

[0004] To overcome the above shortcomings, this utility model provides a weeding device for broad bean fields that prevents root damage.

[0005] The technical solution of this utility model is:

[0006] A weeding device for broad bean fields to prevent root damage includes a mounting plate and two hemispherical clamping blocks symmetrically mounted on the mounting plate. Protective pads are installed on the outer walls of the clamping blocks. An anti-slip pad is fixedly connected to the outer wall of each clamping block near its opposite side. The anti-slip pad has horizontally arranged anti-slip teeth on its outer wall. A connecting rod is integrally formed on the outer wall of each clamping block near the mounting plate. A wedge mechanism for driving the two connecting rods is installed inside the mounting plate. The wedge mechanism includes a wedge body fixed to the connecting rod and a double-ended slider. The two ends of the double-ended slider are slidably connected to the two wedge bodies respectively. A U-shaped operating frame is fixedly mounted on the side of the mounting plate away from the clamping blocks, and a pull rod fixedly connected to the double-ended slider is installed inside the U-shaped operating frame. The symmetrically arranged hemispherical clamping blocks, combined with anti-slip pads and anti-slip teeth, can stably clamp the weed stems during weeding, avoiding direct contact with the soil and damage to the roots. The linkage design of the inclined wedge mechanism and the pull rod allows the operator to control the opening and closing of the clamping blocks with one hand through the U-shaped operating frame, achieving precise weeding and greatly improving work efficiency and the protection of broad bean roots.

[0007] As a preferred technical solution, the mounting plate has a movable groove for the connecting rod to move within it. A limiting rod is fixedly connected within the movable groove, and the limiting rod is plugged into the connecting rod. The movable groove and the limiting rod ensure linear movement of the connecting rod, prevent deviation during clamping, and improve the stability of the weeding operation.

[0008] As a preferred technical solution, the mounting plate has a mounting groove for mounting the wedge mechanism. A limiting groove is formed at the top and bottom of the mounting groove, and limiting strips are integrally formed at the top and bottom of the slider, slidingly connected to the limiting grooves. The sliding cooperation between the limiting grooves and the limiting strips restricts the movement trajectory of the double-headed slider, preventing jamming or misalignment of the wedge mechanism during operation, and ensuring the long-term reliable operation of the equipment.

[0009] As a preferred technical solution, the mounting plate has a slot for insertion and connection with the pull rod, and the slot communicates with the interior of the mounting groove. The slot design provides guiding support for the pull rod, enabling more precise transmission of operating force to the wedge mechanism and improving the opening and closing response speed of the clamping block.

[0010] As a preferred technical solution, a handle is fixedly connected to the end of the pull rod away from the mounting plate, and the handle is located near the end of the U-shaped operating frame away from the mounting plate. The handle's position near the end of the U-shaped operating frame is ergonomic, reduces hand fatigue during long-term operation, and improves operating comfort.

[0011] As a preferred technical solution, a handle is fixedly connected to the top of the middle part of the U-shaped operating frame, and the handle is U-shaped. The U-shaped handle facilitates the operator's two-handed control of the equipment, and allows for more flexible adjustment of the weeding angle and force when operating in complex terrain.

[0012] As a preferred technical solution, a fixing plate is fixedly connected to the outer wall of the pull rod near the mounting plate. Two guide shafts are symmetrically fixedly connected to the fixing plate near the mounting plate. The mounting plate has insertion holes for the guide shafts. A spring is provided on the outer side of each guide shaft, with both ends of the spring fixedly connected to the mounting plate and the fixing plate, respectively. This combination of spring and guide shaft design allows the clamping block to remain open when no external force is applied, and it automatically resets after operation, simplifying the operation process.

[0013] As a preferred technical solution, when the spring is at its original length, the double-ended slider moves to one end closer to the spherical clamping block, and the two spherical clamping blocks move away from each other. With the spring at its original length, the clamping blocks separate, providing an initial opening position for the next weeding operation and improving operational continuity.

[0014] Compared with the prior art, the beneficial effects of this utility model are:

[0015] This invention utilizes symmetrically arranged hemispherical clamping blocks, along with anti-slip pads and anti-slip teeth, to stably clamp weed stems during weeding, preventing direct contact with the soil and root damage. The linkage design of the inclined wedge mechanism and the pull rod allows operators to control the opening and closing of the clamping blocks with one hand via the U-shaped operating frame, achieving precise weeding and significantly improving work efficiency and the protection of broad bean roots.

Detailed Implementation

[0022] The technical solutions of the present utility model will be clearly and completely described below with reference to the accompanying drawings. 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.

[0023] Please refer to Figures 1-4. This utility model provides a technical solution:

[0024] The weeding equipment for broad bean fields that prevents root damage includes a mounting plate 2 and two hemispherical clamping blocks symmetrically mounted on the mounting plate 2. Protective pads are installed on the outer walls of the clamping blocks. An anti-slip pad 10 is fixedly connected to the outer wall of each clamping block near the opposite side. The outer wall of the anti-slip pad 10 is provided with horizontally arranged anti-slip teeth. A connecting rod 11 is integrally formed on the outer wall of each clamping block near the mounting plate 2. A wedge mechanism for driving the two connecting rods 11 is installed inside the mounting plate 2. The wedge mechanism includes a wedge body 25 fixed to the connecting rod 11 and a double-headed slider 26. The two ends of the double-headed slider 26 are slidably connected to the two wedge bodies 25 respectively. A U-shaped operating frame 3 is fixedly installed on the side of the mounting plate 2 away from the clamping blocks, and a pull rod 4 fixedly connected to the double-headed slider 26 is installed inside the U-shaped operating frame 3. The symmetrically arranged hemispherical clamping blocks 1, together with the anti-slip pads 10 and anti-slip teeth, can stably clamp the weed stems during weeding, avoiding direct contact with the soil and damage to the roots. The linkage design of the inclined wedge mechanism and the pull rod 4 allows the operator to control the opening and closing of the clamping blocks with one hand through the U-shaped operating frame 3, achieving precise weeding and greatly improving work efficiency and the protection effect of broad bean roots.

[0025] In a preferred embodiment, the mounting plate 2 has a movable groove 21 for the connecting rod 11 to move. A limiting rod 24 is fixedly connected within the movable groove 21 and is plugged into the connecting rod 11. The movable groove 21 and the limiting rod 24 ensure that the connecting rod 11 moves linearly, prevent deviation during clamping, and improve the stability of the weeding operation.

[0026] In a preferred embodiment, the mounting plate 2 has a mounting groove 20 for mounting the wedge mechanism. The top and bottom of the mounting groove 20 each have a limiting groove 27. The top and bottom of the slider each have an integrally formed limiting strip 260 that slides through the limiting groove 27. The sliding engagement between the limiting groove 27 and the limiting strip 260 restricts the movement trajectory of the double-headed slider 26, preventing jamming or misalignment of the wedge mechanism during operation and ensuring the equipment's long-term reliable operation.

[0027] In a preferred embodiment, the mounting plate 2 has a slot 22 for insertion and connection with the pull rod 4, and the slot 22 communicates with the interior of the mounting groove 20. The slot 22 is designed to provide guiding support for the pull rod 4, so that the operating force is transmitted to the wedge mechanism more accurately and the opening and closing response speed of the clamping block is improved.

[0028] In a preferred embodiment, a handle 40 is fixedly connected to the end of the pull rod 4 away from the mounting plate 2. The handle 40 is located near the end of the U-shaped operating frame 3 away from the mounting plate 2. The position of the handle 40 near the end of the U-shaped operating frame 3 is ergonomic, reduces hand fatigue during long-term operation, and improves operating comfort.

[0029] As a preferred embodiment, a handle 30 is fixedly connected to the top of the middle part of the U-shaped operating frame 3. The handle 30 is U-shaped. The U-shaped handle 30 makes it easier for the operator to control the equipment with both hands, and allows for more flexible adjustment of the weeding angle and force when working in complex terrain.

[0030] In a preferred embodiment, a fixing plate 41 is fixedly connected to the outer wall of the pull rod 4 near the mounting plate 2. Two guide shafts 43 are symmetrically fixedly connected to the fixing plate 41 near the mounting plate 2. The mounting plate 2 has insertion holes 23 for inserting into the guide shafts 43. A spring 42 is provided on the outer side of the guide shafts 43, and both ends of the spring 42 are fixedly connected to the mounting plate 2 and the fixing plate 41, respectively. The combination design of the spring 42 and the guide shafts 43 allows the clamping block to remain in an open state when no external force is applied, and it can automatically reset after operation, simplifying the operation process.

[0031] In a preferred embodiment, when the spring 42 is at its original length, the double-ended slider 26 moves to one end near the spherical clamping block 1, and the two spherical clamping blocks 1 move away from each other. With the spring 42 at its original length, the clamping blocks separate, providing an initial opening position for the next weeding operation and improving operational continuity.

[0032] In the initial state of use, the spring 42 is at its original length, the double-headed slider 26 is located near one end of the clamping block, and the two hemispherical clamping blocks 1 are separated. The operator holds the U-shaped handle 30 with one hand to stabilize the device and the handle 40 with the other hand, adjusting the device angle through the U-shaped operating frame 3, aligning the open clamping blocks with the base of the target weed stem. Pulling the handle 40 moves the pull rod 4 away from the mounting plate 2, causing the double-headed slider 26 to slide along the limiting groove 27. The double-headed slider 26 pushes the two inclined wedge bodies 25 to move in the opposite direction through the inclined surface, forcing the connecting rod 11 to slide linearly along the limiting rod 24. The two clamping blocks gradually close, and the anti-slip pad 10 and anti-slip teeth tightly adhere to the weed stem. At this time, the U-shaped operating frame 3 is pulled upward, using friction to remove the entire weed, and the protective pad prevents external force from damaging the broad bean plant. After releasing handle 40, spring 42 elastically resets and pushes fixed plate 41, causing pull rod 4 to drive double-headed slider 26 back to its initial position. The clamping block automatically opens, ready for the next weeding operation. This device converts linear motion into opposing motion through a wedge mechanism. Combined with the spring 42 reset and guide limit design, it achieves precise weeding that can be controlled by one hand, effectively avoiding the root damage problem of traditional tools, and significantly improving weeding efficiency and crop protection.

[0033] The foregoing has shown and described the basic principles, main features, and advantages of this utility model. Those skilled in the art should understand that this utility model is not limited to the above embodiments. The embodiments and descriptions in the specification are merely preferred examples and are not intended to limit the utility model.
