Semi-active roller weeding knife

Abstract

The semi-active roller weeding knife comprises a blade, a blade holder, a buffer spring, blade teeth, a bearing, a blade shaft, and an electromagnetic clutch. The blade is mounted on the blade holder, which relies on the buffer spring to cushion the blade, effectively removing weeds of varying depths. The blade of the semi-active roller weeding knife has blade teeth mounted outside the blade shaft, with a bearing mounted on one side and an electromagnetic clutch mounted on the other. The working process of the semi-active roller weeding knife is as follows: 1. The electromagnetic clutch is energized, the blade teeth are fixed to the blade shaft, and the blade teeth cut the weeds. 2. As more weeds are cut, the blade resistance increases, reaching a set value 1. 3. The electromagnetic clutch is de-energized, the blade teeth disengage from the blade shaft, the blade teeth release the weeds, and the blade resistance decreases, reaching a set value 2. 4. Steps 1 to 3 are repeated. 5. The weeding task is completed. The beneficial effects of this invention are: it inherits the existing advantages of roller weeding knives, has a simple driving method, and provides good weeding effect. The engagement and disengagement of the electromagnetic clutch enables both the removal of deep-rooted weeds and ensures continuous operation of the weeding knife.

Description

(I) Technical Field

[0001] This utility model relates to weeding tools, and more particularly to a semi-active roller weeding tool. (II) Background Technology

[0002] Roller weed cutters hold a significant share in the market due to their high efficiency and labor-saving nature. Their application is mature, their drive mechanism is simple, and their weeding effect is excellent, proven by the market. Most roller weed cutters on the market are unpowered, rotating discs propelled by the weeding trolley, using their teeth to remove weeds. This method is effective for shallow-rooted weeds but ineffective against deep-rooted ones.

[0003] Therefore, it is necessary to develop a semi-active roller weeding knife that can easily and effectively eradicate deep-rooted weeds. (III) Utility Model Content

[0004] The purpose of this invention is to develop a semi-active roller weeding knife that can easily and effectively eradicate weeds.

[0005] To achieve the above objectives, the semi-active roller weed cutter proposed in this utility model comprises a cutter, a cutter holder, a buffer spring, cutter teeth, a bearing, a cutter shaft, and an electromagnetic clutch.

[0006] The blades are mounted on a blade holder, which uses a buffer spring to cushion the blades and remove weeds with roots at different depths.

[0007] The semi-active roller weeding blade has blades mounted on the outside of the blade shaft, with a bearing mounted on one side and an electromagnetic clutch mounted on the other.

[0008] The semi-active roller weed cutter operates as follows: 1. The electromagnetic clutch is energized, the blade teeth are fixed to the cutter shaft, and the blade teeth cut the weeds. 2. As more weeds are cut, the blade resistance increases, reaching the set value 1. 3. The electromagnetic clutch is de-energized, the blade teeth are released from the cutter shaft, the blade teeth release the weeds, and the blade resistance decreases, reaching the set value 2. 4. Repeat steps 1 to 3. 5. The weeding task is completed.

[0009] Compared with existing technologies, the advantages of this utility model are: it inherits the existing advantages of roller weeding blades, has a simple driving method, and provides good weeding effect. The engagement and disengagement of the electromagnetic clutch enables both the removal of deep-rooted weeds and the continuous operation of the weeding blades. (iv) Description of the attached drawings

[0010] The specific structure of this utility model is given by the following embodiments and accompanying drawings:

[0011] Appendix Figure 1 This is an isometric view of the semi-active roller weeding blade structure of this utility model.

[0012] Appendix Figure 2 This is a side view of the semi-active roller weed cutter of this utility model.

[0013] Among them, (1) cutting tool, (2) tool holder, (3) buffer spring, (11) cutting tooth, (12) bearing, (13) cutting shaft, and (14) electromagnetic clutch. (V) Detailed Implementation

[0014] See attached document Figure 1 The blade (1) is mounted on the blade holder (2), and the blade holder (2) uses the buffer spring (3) to buffer the blade (1) and remove weeds with roots of different depths.

[0015] See attached document Figure 2 The cutting tool (1) has cutting teeth (11) mounted on the outside of the cutting shaft (13), and a bearing (12) is mounted on one side and an electromagnetic clutch (14) is mounted on the other side.

[0016] The working process of a semi-active roller weed cutter is as follows:

[0017] 1. When the electromagnetic clutch (14) is energized, the blade (11) is fixed to the blade shaft (13), and the blade (11) cuts the weeds.

[0018] 2. As the amount of weeds cut increases, the resistance of the blade (1) increases, reaching the set value of 1.

[0019] 3. When the electromagnetic clutch (14) is de-energized, the blade (11) and the blade shaft (13) are disengaged. The blade (11) puts down the weeds, and the resistance of the blade (1) decreases, reaching the set value 2.

[0020] 4. Repeat steps 1 through 3.

[0021] 5. Complete the weeding task.

[0022] Setting value 1 is greater than setting value 2.

[0023] This utility model has the following features: 1. It inherits the existing advantages of roller weeding blades, with a simple driving method and good weeding effect. 2. By using an electromagnetic clutch, it can remove deep-rooted weeds while ensuring the continuous operation of the weeding blade.
