Description

Technical Field

[0001] This utility model relates to the field of weeding machine technology, and in particular to a towable weeding machine. Background Technology

[0002] In the past, manual weeding was a commonly used method. While manual weeding can precisely remove weeds to a certain extent, it is extremely inefficient. Taking large areas of farmland as an example, hiring a large workforce for weeding not only consumes a significant amount of time and labor costs, but also, during busy farming seasons, labor shortages often prevent timely completion of weeding work, affecting crop growth and harvest. Furthermore, manual weeding is physically demanding; prolonged bending and working puts a considerable strain on the health of workers. With the development of technology, mechanized weeding has gradually emerged. Ordinary large weeding machines, in open, large-area fields such as vast plains, can quickly clear weeds thanks to their powerful engines and efficient operation, greatly improving weeding efficiency. However, these weeding machines have significant limitations. In areas with special terrain or layouts, such as orchards and woodlands, where trees are densely distributed, large weeding machines struggle to maneuver flexibly among the trees and cannot effectively clear weeds between them. If weeds in these areas are not removed in time, they will compete with trees for nutrients, water and sunlight, affecting the growth and development of trees, reducing fruit yield and quality, and may even lead to the breeding and spread of pests and diseases.

[0003] Most existing towed weed cutters are mounted on the back of the drive structure, which moves the weed cutter to remove weeds. However, towed weed cutters often have poor flexibility when facing complex terrain, such as clearing weeds between trees or uneven ground, making it inconvenient to carry out weed removal operations. Therefore, a towed weed cutter has been proposed. Utility Model Content

[0004] (a) Technical problems to be solved

[0005] The purpose of this utility model is to provide a towable weed cutter, which solves the problem mentioned in the background art that most existing towable weed cutters are installed on the back of the drive structure, and the drive structure drives the weed cutter to move and thus achieve the removal of weeds. However, towable weed cutters often have poor flexibility when facing complex terrain, such as clearing weeds between trees and uneven ground, making it inconvenient to carry out weed removal operations.

The auxiliary mechanism includes a positioning hook A fixedly connected to the surface of the extension block, a torsion spring inserted into the end of the positioning hook A, a positioning hook B inserted into the end of the torsion spring, a placement plate fixedly connected to the end of the positioning hook B, and an auxiliary weeding disc installed at the bottom of the placement plate.

[0008] As a further embodiment of this utility model, two connecting blocks are fixedly connected to the bottom of the rotating shaft. The connecting blocks have through holes inside, and the connecting blocks serve to connect the limiting rod.

[0009] As a further embodiment of this utility model, a limiting rod is slidably connected inside the through hole, and support blocks are fixedly connected to both sides of the limiting rod. The limiting rod serves to limit the position of the connecting block.

[0010] As a further embodiment of this utility model, a rotating hole is provided on one side of the placement plate. The rotating hole is rotatably connected to the surface of the rotating shaft, and the rotating shaft serves to support the placement plate.

[0011] As a further embodiment of this utility model, two fixed joints are fixedly connected to the left side of the main body of the weeder, and two connecting rods are rotatably connected to the surface of the fixed joints. The connecting rods serve to connect to the external support structure.

[0014] (III) Beneficial Effects

[0015] This utility model provides a towable weed cutter, which has the following beneficial effects:

[0016] 1. This towable weeder, through the setting of an auxiliary mechanism, when used, because there are trees in the weeding area, therefore, an auxiliary weeding disc is installed on one side of the main body of the weeder. A torsion spring is connected to one side of the auxiliary weeding disc. The reverse force provided by the torsion spring drives the auxiliary weeding disc to reciprocate, shuttling back and forth between two trees, thereby achieving the effect of weeding between trees, improving the flexibility and comprehensiveness of the main body of the weeder when weeding.

[0017] 2. This towable weeder features a lifting mechanism. When the equipment is idle, the auxiliary weeding disc is in constant contact with the ground, which can cause wear and tear. Therefore, a lifting structure is installed on one side of the auxiliary weeding disc. Activating the hydraulic rod on the rotating shaft on one side of the auxiliary weeding disc causes the shaft at its end to adjust its height under the control of a limit rod on one side. This effectively reduces wear and tear on the auxiliary weeding disc caused by prolonged contact with the ground when idle, extending the equipment's service life. Attached Figure Description

An extension block 4 is fixedly connected to the surface of the lifting mechanism 3, and an auxiliary mechanism 5 is fixedly connected to the surface of the extension block 4. The structure 5 is designed to remove weeds between trees, improving the flexibility and comprehensiveness of the weeding machine body 1 during weeding. The lifting mechanism 3 includes a hydraulic rod 301 fixedly connected to the surface of the connecting plate 2, and a rotating shaft 302 fixedly connected to the end of the hydraulic rod 301. The auxiliary mechanism 5 includes a positioning hook A501 fixedly connected to the surface of the extension block 4, a torsion spring 502 inserted into the end of the positioning hook A501, a positioning hook B503 inserted into the end of the torsion spring 502, a placement plate 504 fixedly connected to the end of the positioning hook B503, and an auxiliary weeding disc 505 installed at the bottom of the placement plate 504.

[0025] Two connecting blocks 6 are fixedly connected to the bottom of the rotating shaft 302. The connecting blocks 6 have through holes inside, and the connecting blocks 6 serve to connect the limiting rod 7.

[0026] A limiting rod 7 is slidably connected inside the through hole. Support blocks 8 are fixedly connected to both sides of the limiting rod 7. The limiting rod 7 serves to limit the position of the connecting block 6.

[0027] A rotating hole is provided on one side of the placement plate 504. The rotating hole is rotatably connected to the surface of the rotating shaft 302. The rotating shaft 302 serves to support the placement plate 504.

[0028] Two fixed joints 9 are fixedly connected to the left side of the weeder body 1. Two connecting rods 10 are rotatably connected to the surface of the fixed joints 9. The connecting rods 10 serve to connect to the external support structure.

[0029] A fixing plate 11 is fixedly connected to the end of the connecting rod 10, and a rotating joint 12 is fixedly connected to one side of the fixing plate 11. The rotating joint 12 drives the connecting rod 10 to rotate.

[0030] The top surfaces of the weed cutter body 1 are fixedly connected to the edges of both sides of the top surface with lifting rings 13. The surface of the lifting rings 13 is provided with positioning holes, which facilitates the handling of the equipment.

[0031] In this invention, the working steps of the device are as follows:

[0032] First step: When in use, since there are trees in the weeding area, an auxiliary weeding disc 505 is installed on one side of the main body 1 of the weeder. A torsion spring 502 is connected to one side of the auxiliary weeding disc 505. The reverse force provided by the torsion spring 502 drives the auxiliary weeding disc 505 to reciprocate and shuttle back and forth between the two trees.

[0033] The second step: When the equipment is idle, the auxiliary weeding disc 505 wears out due to prolonged contact with the ground. Therefore, a lifting structure is installed on one side of the auxiliary weeding disc 505. Activating the hydraulic rod 301 on the rotating shaft 302 on one side of the auxiliary weeding disc 505 causes the rotating shaft 302 at its end to adjust its height under the limit of the limiting rod 7 on one side. It should be noted that the equipment structure and accompanying drawings of this utility model mainly describe the principle of this utility model. The technical details of the device's power mechanism, power supply system, and control system are not fully described.
