Tunnel blasting gravel recycling stone crusher with uniform crushing effect

Abstract

The invention relates to the field of gravel, in particular to a tunnel blasting gravel recycling stone crusher with uniform crushing effect. The tunnel blasting gravel recycling stone crusher comprises a protection box, a gravel vibration device, a circulating conveying device, a guide mechanism, a discharging device and a conveying device, wherein a first rectangular groove, a second rectangular groove and a third rectangular groove are formed in the top, the bottom and one end of the protection box correspondingly; the gravel vibration device is arranged on the protection box; and the discharging device is arranged under the protection box. Through tight and coordinated operation of a crushing assembly and a vibration assembly, the gravel is uniformly crushed, meanwhile, the crushed gravel is sorted to obtain qualified gravel and unqualified gravel, the qualified gravel is directly conveyed out through the discharging device, the unqualified gravel is moved to a turnover mechanism through the conveying device, then the turnover mechanism is driven by a lifting mechanism to move to the guide mechanism, the unqualified gravel is poured into the crushing device through the guide mechanism to be subjected to secondary crushing, the labor amount input is reduced, and high automation of operation is achieved.

Description

technical field [0001] The invention relates to the field of stone crushing, in particular to a tunnel blasting stone recycling stone crusher with uniform crushing effect. Background technique [0002] During the tunnel blasting process, a lot of rubble will be produced, which can be used as building materials. However, due to the uneven size of the blasted crushed stones, it is necessary to use a stone crusher to crush the stones. [0003] The stone crushers in the prior art tend to have uneven stone sizes during the stone crushing process, so it is necessary to perform secondary crushing on unqualified stones. At present, the stones that need secondary crushing are manually crushed. Lifting to a high place for secondary crushing, the speed is relatively slow, which affects the efficiency of crushing stones. Therefore, a more convenient and easy-to-operate machine is urgently needed to carry out the work. Contents of the invention [0004] In order to solve the above te...
