Returning extensible system used for impact crusher

Abstract

The invention belongs to the technical field of crushers, and particularly relates to a returning extensible system used for an impact crusher. The returning extensible system used for the impact crusher comprises a tail-end telescopic device which is arranged at the tail end of a returning transmission rack and has a telescopic function, and a head-end lifting device which is located at the headend of the returning transmission rack and has a lifting function; the head-end lifting device comprises a four-bar linkage jacking assembly, and a head supporting assembly which is used for being connected with the four-bar linkage jacking assembly and the returning transmission rack; and the tail-end telescopic device comprises a telescopic cylinder fixed to a car body, and a tail supporting assembly which is used for being connected with the telescopic cylinder and the returning transmission rack. By means of the returning extensible system used for the impact crusher, online folding and storage and lifting functions of the returning transmission rack can be achieved, so that the efficiency of transportation work of the impact crusher is effectively improved.

Description

technical field [0001] The invention belongs to the technical field of pulverizers, and in particular relates to a return stretching system for impact crushers. Background technique [0002] The impact crusher is called impact crusher for short. It is mainly used for the processing of metallurgy, chemical industry, building materials, hydropower and other materials that often need to be relocated, especially for the pre-crushing of mobile stones such as highways, railways, and hydropower projects. When the impact crusher works, firstly, the material is sent from the hopper to the feeder, and then the material is sent to the impact crusher through the vibration of the feeder. After crushing, the material falls to the conveyor, and the conveyor sends the material to the return material. The sieve and return sieve separate the finished product from the unfinished product through vibration; the unfinished material falls into the transition conveyor, and the transition conveyor t...

Problems solved by technology

The traditional return conveyor frame is a monolithic structure. Affected by the height of the return material, it is normal for the material rack to be super high and long; however, the super high and long return conveyor frame obviously causes the overall size of the impact crusher to increase. , which makes the transportation operation extremely inconvenient

At present, when the impact crusher is transported, the return conveyor frame needs to be disassembled as a whole, that is, the return conveyor frame and the impact crusher are transported separately; after the impact crusher is transported to the operating site, the return conveyor frame is reassembled. The operation is extremely cumbersome and the transportation efficiency is extremely low, which brings many troubles to the actual use of the impact crusher
