Description

Technical Field

[0001] The utility model belongs to the field of agricultural machinery, and particularly relates to a disc for a strip tillage machine. Background Art

[0002] The strip tillage machine is an essential agricultural implement accepted by the majority of farmers for conservation tillage, and plays a key role in promoting conservation tillage agronomy. However, the existing disc for a strip tillage machine is formed by welding a disc and a tool magazine, which is particularly prone to damage. During operation, the disc often deforms and breaks, and the tool magazine deforms and cracks, etc. Repairing and replacing are very laborious and delay farming seasons. In view of the above situation, the disc for a strip tillage machine provided by the utility model can solve the above problems. The disc for a strip tillage machine provided by the utility model is formed by welding one main disc and two sub - discs. The main disc is located in the middle, and the sub - discs are on both sides. Since the sub - disc is an annular disc, after welding, it forms an integral tool magazine, thus avoiding the problem that the existing welded tool magazine is easily damaged. Content of the Utility Model

[0003] The purpose of the utility model is to provide a disc for a strip tillage machine to solve the problems put forward in the above background art.

[0004] To solve the above technical problems, the utility model provides the following technical solution: A disc for a strip tillage machine, including a main disc, sub - discs, a tool magazine groove opened on the main disc, bolt holes for fixing tools, welding openings on the sub - discs, positioning holes, and welding beads of the sub - discs, characterized in that the disc for a strip tillage machine is formed by combining and welding the main disc and the sub - discs.

[0005] Further, a tool magazine groove is opened on the main disc. After the main disc and the sub - discs are welded together, they form a tool magazine. Since the tool magazine is formed by the main disc and two sub - discs, it has high strength and is not easily damaged.

[0006] Further, corresponding positioning holes are opened on the main disc and the sub - discs. After the positioning holes are aligned, it can ensure that the positions of the main disc and the sub - discs are fixed during welding and will not shift.

[0007] Further, bolt holes for fixing tools are opened on the sub - discs. When the main disc and the sub - discs are welded together and the positioning holes are aligned, the bolt holes for fixing tools are exactly at the appropriate positions of the tool magazine groove opened on the main disc, so as to fix the rotary tillage blades.

[0008] Further, welding openings are opened on the sub - discs. Through the welding openings on the sub - discs, the tool magazine part formed by the main disc and the sub - discs is firmly welded into one body, and there is no welding inside the tool magazine and no weld interference, so the rotary tillage blades can be inserted and removed easily.

[0009] Further, welding beads are formed on the auxiliary cutter disc, and the main cutter disc and the auxiliary cutter disc are firmly welded into one body through the welding beads of the auxiliary cutter disc.

[0010] Compared with the prior art, the beneficial effects achieved by the present utility model are as follows: The structure of this utility model is compact, ingeniously and reasonably designed. The integrated tool magazine formed by welding the main cutter disc and the auxiliary cutter disc has much higher strength than the existing welded tool magazine, making the cutter disc of the ridging machine more durable, reducing the failure rate of the machine, and saving farming time for farmers.

[0016] The following further describes the present utility model with reference to the drawings and embodiments.

[0017] As Figures 1-3 shown, the present utility model includes a main cutter disc 1, on which a tool magazine slot 3 and a positioning hole 6 are opened. There is also an auxiliary cutter disc 2, on which there are: bolt holes 4 for fixing the cutter, welding opening 5 on the auxiliary cutter disc, positioning hole 6, and welding bead 7 of the auxiliary cutter disc. Place the main cutter disc 1 in the middle, place one auxiliary cutter disc 2 on each side, fix their relative positions through the positioning holes 6, perform welding at the welding opening 5 on the auxiliary cutter disc, and also perform welding at the welding bead 7 of the auxiliary cutter disc, so that the main cutter disc 1 and two auxiliary cutter discs 2 form the cutter disc of the ridging machine.
