Description

Technical Field

[0001] The utility model relates to the technical field of gardening and greening, in particular to a weeding tool. Background Art

[0002] Wild vegetation (such as weeds) is ubiquitous in experimental fields, experimental plots, grasslands, and gardens. Weeds are extremely resilient, fiercely competing for limited sunlight and nutrients in the lawn or garden, severely hindering the growth of established flowers and plants. Therefore, effective weed control methods are urgently needed. Conventional weed control methods operate solely on the surface, removing only the weed branches and leaves but not the roots deep within. Once suitable weather conditions occur, weeds will regrow, wasting the manpower and financial resources previously invested. Therefore, complete weed control is achieved only by eradicating weeds at their roots.

[0003] There are several common methods for weed removal: One is direct manual removal, where the operator grasps the weed branches and leaves with their hands and pulls them outwards to free the roots from the soil. However, this purely manual method is laborious and inefficient. Another method involves using hand tools, such as a spade or shovel, to remove the weeds by their roots. For example, a multifunctional manual weed puller uses a digging blade and a target to remove weeds. However, these tools are often cumbersome, inefficient, and incomplete, often damaging existing plants. Utility Model Content

[0004] The purpose of the utility model is to provide a weeding tool for solving the problem mentioned in the above background technology that the existing equipment is inconvenient for removing grass roots.

[0006] Furthermore, the telescopic handheld part includes a control box, a telescopic sleeve provided on one end of the control box, and a spline telescopic rod connected to the support plate and located in the telescopic sleeve; an electric push rod is provided in the control box, the output shaft of the electric push rod passes through the control box and is connected to one end of the spline telescopic rod, and the telescopic sleeve slides in conjunction with the spline telescopic rod.

[0007] Furthermore, the clamping assembly includes a positioning plate connected to the support plate through a column, and a rotating disk rotatably connected to the positioning plate and connected to the motor output shaft; four sliding grooves perpendicular to each other are horizontally opened on the positioning plate, one end of the clamping plate is slidably connected to the sliding groove, and the rotating disk is circumferentially opened with four equidistant arc grooves, and a slider is provided on one end of the clamping plate, and the slider is located in the arc groove and slides with the arc groove.

[0008] Furthermore, the weeding blade consists of an arc-shaped plate and a conical plate arranged at the bottom of the arc-shaped plate.

[0009] Furthermore, a cover plate is detachably connected to the other end of the control box, and a battery is installed on the cover plate. The battery is respectively connected to the motor and the electric push rod.

[0010] Furthermore, handles are provided on both sides of the control box, and the two handles are respectively provided with a first control switch and a second control switch connected to the motor and the electric push rod.

[0011] Compared with the prior art, the beneficial effects of the present invention are as follows:

[0012] The utility model is used for removing weeds, and the grass roots are removed together. The electric push rod drives the spline telescopic rod to move downward, thereby driving the weeding mechanism to extend into the soil, and then the motor drives the four clamping plates to move closer to each other, thereby driving the four weeding blades to move closer to each other, so that the weeds and grass roots are collected and clamped together, and then the electric push rod drives the spline telescopic rod to move upward, so that the weeding mechanism is taken out of the soil, and finally the motor is reversed to drive the four weeding blades to move away from each other to remove the removed weeds and grass roots. The device allows the staff to extend the weeding mechanism into the soil through the telescopic handpiece, and then removes the weeds and grass roots through the clamping assembly, so that the weeds and grass roots are completely removed, thereby improving the weeding efficiency.

[0019] See also Figures 1 to 4 A weeding tool, comprising a retractable telescopic handheld portion 1 and a weeding mechanism 2 for removing grass roots, which is provided on the telescopic handheld portion 1. The weeding mechanism 2 is composed of a support plate 3 connected to the end of the telescopic handheld portion 1, a motor 4 provided on the support plate 3, and a clamping assembly 5 connected to the support plate 3 and in transmission connection with the motor 4. When removing grass roots, the telescopic handheld portion 1 is extended to drive the weeding mechanism 2 into the soil, and then the motor 4 drives the clamping assembly 5 to operate. Under the action of the clamping assembly 5, the L-shaped clamps respectively provided on the four ends of the clamping assembly 5 and connected to the clamping assembly 5 slide. The holding plates 6 are close to each other, thereby driving the weeding blades 7 respectively provided at the ends of the four clamping plates 6 to approach each other. Since the weeding blade 7 is composed of an arc plate 17 and a conical plate 18 provided at the bottom of the arc plate 17, when the four arc plates 17 are close to each other, a ring structure is formed. When the four conical plates 18 are close to each other, a hollow conical structure is formed, clamping the grass roots therein, and then the grass roots are brought out of the soil by contracting the telescopic handheld part 1. Finally, the four weeding blades 7 are driven away from each other by the clamping assembly 5 to remove the grass roots, collect and process them, and then fill the removed soil back to its original place.

[0020] The telescopic handheld part 1 for driving the weeding mechanism 2 to move is composed of a control box 8, a telescopic sleeve 9 provided on one end of the control box 8, and a spline telescopic rod 10 connected to the support plate 3 and located in the telescopic sleeve 9. A cover plate 19 is detachably connected to the other end of the control box 8. An electric push rod 11 is provided in the control box 8, and a battery 20 for providing power to the electric push rod 11 is installed on the cover plate 19. If the weeding mechanism 2 is to be controlled to extend into the soil, the staff will hold the handles 22 provided on both sides of the control box 8 and press the first control switch 21 provided on one of the handles 22 and connected to the electric push rod 11. Then, the electric push rod 11 provided in the control box 8 is started by the first control switch 21, and the battery provides power for it, driving the spline telescopic rod 10 slidingly matched with the telescopic sleeve 9 to move downward, thereby driving the weeding mechanism 2 to extend into the soil. In order to save installation space, the electric push rod 11 is preferably a multi-section electric push rod.

[0021] The clamping assembly 5 for driving the four clamping plates 6 to move closer to or away from each other is composed of a positioning plate 12 connected to the support plate 3 through a column, and a rotating disk 13 rotatably connected to the positioning plate 12 and connected to the output shaft of the motor 4. In order to achieve the above-mentioned effect, four mutually perpendicular slide grooves 14 are horizontally opened on the positioning plate 12, and one end of the clamping plate 6 is slidably connected to the slide groove 14, and then the rotating disk 13 is provided with four equally spaced arc grooves 15 along the circumferential direction. Finally, a slider 16 is provided on one end of the clamping plate 6, and the slider 16 is located in the arc groove 1 5 and slides with the arc groove 15. The above-mentioned battery 20 and the second control switch 23 are connected to the motor 4. When in use, the second control switch 23 provided on the other handle 22 is used to control the forward rotation of the motor 4. The battery provides power for it. Since the motor 4 is specifically a stepping motor, the angle and number of rotations can be controlled to rotate, so that the rotating disk 13 rotates, driving the slider 16 that slides with the arc groove 15 to move. Under the limit of the slide groove 14, the four clamping plates 6 are brought closer to each other. If the four clamping plates 6 are to be moved away from each other, the motor 4 can be controlled to rotate in the reverse direction.

[0022] The working principle of the present utility model is as follows: when weeding the roots, the staff places the weeding mechanism 2 above the weeds, and then the staff holds the handle 22 to hold the device against the weeds, and then starts the electric push rod 11 by pressing the first control switch 21, and the electric push rod 11 drives the spline telescopic rod 10 to move down, and the weeding mechanism 2 is extended into the soil, and then the motor 4 is started by the second control switch 23, and the motor 4 drives the rotating disk 13 to rotate, and drives the slider 16 that slides with the arc groove 15 to move. Under the limit of the slide groove 14, the four clamping plates 6 are close to each other, and the weeds and grass roots are clamped in the four weeding blades 7, and then the electric push rod 11 drives the spline telescopic rod 10 to move up, and the weeds and grass roots are taken out of the soil. Finally, the motor 4 is controlled to reverse, so that the four clamping plates 6 are away from each other, so that the staff can take out the weeds and grass roots for subsequent processing and collection.
