The sheet metal forming roller weeding cutter has the advantages of the roller weeding cutter, the driving mode is simple, and the weeding effect is good. The sheet metal formed roller weeding knife is formed by a sheet metal, and is simple in structure, easy to produce, low in cost and easy to produce on a large scale.

Description

(I) Technical Field

[0001] This utility model relates to weeding tools, and more particularly to a sheet metal forming roller weeding tool. (II) Background Technology

[0002] Roller weed cutters hold a significant share in weeding machine blades due to their high efficiency and labor-saving characteristics. Their market application is mature, their drive mechanism is simple, and their weeding effect is excellent, proven by the market. However, most roller weed cutters on the market are welded components, which limits further cost reduction and automated mass production.

[0003] Therefore, it is necessary to develop a sheet metal forming roller weed cutter that can be mass-produced automatically at extremely low cost. (III) Utility Model Content

[0004] The purpose of this invention is to develop a sheet metal forming roller weed cutter that can be mass-produced automatically at extremely low cost.

[0005] To achieve the above objectives, the sheet metal forming roller weed cutter proposed in this utility model includes: a cutter disc, a cutter plate, reinforcing ribs, cutter teeth, and mounting holes. All of these cutter features are formed from a single piece of sheet metal.

[0006] Cut a piece of sheet metal according to the sheet metal unfolding drawing, cut out the cutter head, cutter teeth, and mounting holes, and make blades and reinforcing ribs on the sheet metal forming machine.

[0007] The four blades, reinforcing ribs, and teeth formed above are bent 90 degrees to the right at intervals, and the other four are bent 90 degrees to the left at intervals. Finally, the gaps between the reinforcing ribs and the blade discs are welded to form the sheet metal forming roller weeding knife of this utility model.

[0008] Compared with the prior art, the advantages of this utility model are: simple structure, easy production, low cost, and easy to carry out mass production. (iv) Description of the attached drawings

[0009] The specific structure of this utility model is given by the following embodiments and accompanying drawings:

[0010] Appendix Figure 1 This is a side view of the sheet metal forming roller weed cutter of this utility model.

[0011] Appendix Figure 2 This is a front view of the sheet metal forming roller weeding blade of this utility model.

[0012] Appendix Figure 3 This is a sheet metal unfolded drawing of the sheet metal forming roller weeding knife of this utility model.

[0013] Among them, (1) cutter head, (2) cutter plate, (3) reinforcing rib, (4) cutter teeth, and (5) mounting holes. (V) Detailed Implementation

[0014] See attached document Figure 1 Appendix Figure 3 According to the appendix Figure 3 The unfolded diagram shows the cutting of a sheet metal piece, cutting out the cutter head (1), cutter teeth (4), and mounting holes (5), and the resulting part is made on a sheet metal forming machine as shown in the attached diagram. Figure 1 The blade (2) and reinforcing rib (3) are shown. This tool is formed from a single sheet metal piece.

[0015] See attached document Figure 1 The four blades (2), reinforcing ribs (3), and blade teeth (4) formed above are bent 90 degrees to the right at intervals, and the other four are bent 90 degrees to the left at intervals. Finally, the gap between the reinforcing ribs (3) and the blade disc (1) is welded to form the sheet metal forming roller weeding knife of this utility model.

[0016] This utility model has the following features:

[0017] 1. The existing advantages of the roller weeding blade are simple driving method and good weeding effect.

[0018] 2. It is formed from a single sheet metal piece, has a simple structure, is easy to produce, has low cost, and is easy to mass-produce.
