Abstract
Description
(I) Technical field
[0001] The invention relates to a weeding knife, in particular to a sheet metal formed roller weeding knife. (II) Background technology
[0002] Roller weeding blades are very important in weeding machine tools due to their high efficiency and labor saving. Roller weeding blades are mature in market application, simple in driving mode, and have good weeding effect, which has been verified by the market. Roller weeding blades on the market are all spliced and welded parts, which cannot further reduce costs and cannot be mass-produced automatically.
[0003] For this reason, it is necessary to develop a sheet metal forming roller weeding knife that can be mass-produced automatically at a very low cost. (III) Summary of the invention
[0004] The purpose of the invention is to develop a sheet metal forming roller weeding knife which can be mass-produced automatically at a very low cost.
[0005] To achieve the above purpose, the sheet metal formed roller weeding knife proposed by the present invention comprises: a knife disc, a knife plate, reinforcing ribs, knife teeth, and mounting holes. The above knife features are all formed from a piece of sheet metal.
[0006] Cut a piece of sheet metal according to the sheet metal unfolding diagram, cut out the cutter disc, cutter teeth, mounting holes, and make the cutter plate and reinforcing ribs on the sheet metal forming machine.
[0007] The four blade plates, reinforcing ribs and blade teeth formed above are bent rightwards by 90 degrees, and the other four are bent leftwards by 90 degrees. Finally, the gap between the reinforcing ribs and the blade disc is welded to form the sheet metal forming roller weeding blade of the present invention.
[0008] Compared with the prior art, the invention has the advantages of simple structure, easy production, low cost and easy large-scale production. (IV) Description of the drawings
[0009] The specific structure of the present invention is given by the following embodiments and the accompanying drawings:
[0010] Attached Figure 1 It is a side view of the sheet metal forming roller weeding knife shaft of the present invention.
[0011] Attached Figure 2 It is a front view of the sheet metal forming roller weeding knife of the present invention.
[0012] Attached Figure 3 It is a sheet metal expansion diagram of the sheet metal forming roller weeding knife of the present invention.
[0013] The invention comprises: (1) a cutter disc, (2) a cutter plate, (3) reinforcing ribs, (4) cutter teeth, and (5) a mounting hole. (V) Specific implementation methods
[0014] See attached Figure 1 , Attachment Figure 3 , according to the attached Figure 3 As shown in the expanded diagram, a sheet metal is cut to form a cutter disc (1), cutter teeth (4), and mounting holes (5). Figure 1 The knife plate (2) and reinforcing ribs (3) shown in the figure are formed from a piece of sheet metal.
[0015] See attached Figure 1 The four blade plates (2), reinforcing ribs (3) and blade teeth (4) formed above are bent rightwards by 90 degrees at intervals, and the other four are bent leftwards by 90 degrees at intervals. Finally, the gap between the reinforcing ribs (3) and the blade disc (1) is welded to form the sheet metal formed roller weeding blade of the present invention.
[0016] The present invention has the following characteristics:
[0017] 1. The existing advantages of Chengqi roller weeding knife are simple driving method and good weeding effect.
[0018] 2. It is formed from a piece of sheet metal, with simple structure, easy production, low cost, and easy to carry out large-scale production.
