Description

Crushing and screening shaft with replaceable stirring block

Technical Field

The utility model relates to the technical field of material crushing, in particular to a crushing and screening shaft with replaceable stirring blocks.

Background

In the construction process of soil, construction waste or other environmental protection projects, the materials need to be processed into smaller materials through screening and crushing equipment or sundries which cannot be biochemically processed need to be cleaned out. In the prior art, the patent documents US10676892B2, WO2017068237a1 relate to a replaceable blade. Simultaneously, as the Chinese utility model patent: 201821973167.6, which relates to replaceable sifting portions, there is also a tendency for them to wear out and require frequent replacement. The parts such as the blade and the screening part are generally of a cast or integrally forged structure, and need to be hardened by integral heat treatment after casting or forging in order to improve the wear resistance. A large number of engineering practices prove that the abrasion of the part is local abrasion, the bottom of the part does not relate to abrasion consumption, and obviously, the structure has the defects of complex processing and high cost.

SUMMERY OF THE UTILITY MODEL

The utility model provides a crushing and screening shaft with replaceable stirring blocks, which aims to solve the technical defects, wherein the stirring blocks are replaceable, and the surface of each stirring block is embedded with a wear-resistant block, so that the wear resistance is improved.

The utility model discloses a crushing and screening shaft with replaceable stirring blocks, which comprises a shaft body, wherein the shaft body is provided with the stirring blocks and a conveying block, the stirring blocks are detachably connected to the shaft body, the conveying block is fixed on the shaft body, a plurality of inner concave holes are arrayed on the surfaces of the stirring blocks and the conveying block, which are far away from the shaft body, wear-resistant blocks are arranged in the inner concave holes, the wear-resistant blocks are made of hard alloy, and the upper end surfaces of the wear-resistant blocks protrude out of the surfaces of the corresponding stirring blocks and the corresponding conveying block.

Above-mentioned technical scheme, its surface that is used for contacting with the material promptly at the up end of stirring piece and transport piece sets up interior concave hole to including the inside wear-resisting piece of inlaying of shrinkage pool, utilize wear-resisting piece to extrude the breakage to the material, thereby avoid stirring the excessive wearing and tearing of piece and transport piece. The wear-resistant block protrudes out of the surface of the stirring block, and is firstly contacted with the wear-resistant block when being contacted with a material, so that the wear to the stirring block is reduced, meanwhile, the area of the wear-resistant block is relatively small, the wear-resistant block can better crush the material when being contacted with the material, and the crushing effect is better.

And the wear-resistant block and the concave hole are in interference fit or welded. The interference fit needs to adopt thermal assembly, or the interference fit and the clearance fit are fixedly connected by welding.

The stirring block passes through the pedestal connection on the axis body, the base is fixed on the axis body, is provided with the connector on the stirring block, the connector is located two relative sides of stirring block respectively with wear-resisting piece, is provided with the cavity that is used for holding the connector on the base, all is provided with the pinhole that link up on connector and base, and the connector is pegged graft through the round pin axle after cooperating with the base. The design of this structure can realize the change to the stirring piece through the dismouting of round pin axle, and is simple and convenient.

The stirring blocks and the conveying blocks are respectively arranged on the shaft body in a spiral shape, and at least one stirring block and at least one conveying block are arranged on any radial section between the stirring blocks at two ends of the shaft body. The design of this structure can ensure the normal transport and the breakage to the material.

According to the crushing and screening shaft with the replaceable stirring block, the replaceable stirring block is adopted, and the wear-resistant block is embedded in the working surface of the stirring block, so that the wear resistance of the stirring block is improved, the wear is reduced, the service life is prolonged, and the replacement frequency is reduced.
