Conveying and crushing device with anti-blocking function

Abstract

The invention discloses a conveying and crushing device with an anti-blocking function. The conveying and crushing device is provided with a crusher, a storage cavity, an upper jaw plate, a lower actuator, a lower jaw plate, fine material holes, a back face, a spring bearing plate, firing pins, holes, an upper actuator, a fine material auxiliary cavity, a width adjusting device, reset springs, anupper opening and a lower opening. Crushed materials are uniform in size, the utilization rate of the materials is high, the crushing efficiency is high, the thicknesses of the lower jaw plate and theupper jaw plate do not need to be set excessively, machine materials are saved, a machine is not very heavy, and energy consumption is low.

Description

technical field [0001] The invention belongs to the field of rock crushing, in particular to a conveying crushing device with an anti-clogging function. Background technique [0002] Existing crushers, which are used in mining and other rock crushing industries, do not have an upper actuator, a spring bearing plate, a return spring, and a striker, but only drive the lower jaw plate around the lower end of the lower jaw plate through the lower and lower actuators. The hinge pivots and the scrap, the above scrap has a simple structure, usually requires the lower actuator to provide a larger pivoting moment, and requires the lower jaw plate to have higher strength, which undoubtedly requires increasing the thickness of the upper jaw plate and the lower jaw plate to improve the strength (Perhaps select the material with higher strength to make the upper jaw plate and the lower jaw plate, and the price of the material with higher strength is half more expensive), and the lower ...

Problems solved by technology

[0002] Existing crushers, which are used in mining and other rock crushing industries, do not have an upper actuator, a spring bearing plate, a return spring, and a striker, but only drive the lower jaw plate around the lower end of the lower jaw plate through the lower and lower actuators. The hinge pivots and the scrap, the above scrap has a simple structure, usually requires the lower actuator to provide a larger pivoting moment, and requires the lower jaw plate to have higher strength, which undoubtedly requires increasing the thickness of the upper jaw plate and the lower jaw plate to improve the strength (Perhaps select the material with higher strength to make the upper jaw plate and the lower jaw plate, and the price of the material with higher strength is half more expensive), and the lower jaw plate is cyclically pivoting (continuously extruding and crushing under the action of the cam mechanism 4, for example) Stone process, that is, the process of the upper jaw plate and the lower jaw plate approaching-leaving-approaching-leaving...), due to the large thickness, the mandibular plate is relatively bulky and the inertial force is also large, and the energy waste is serious in the process of cyclic pivoting. And the crushed material usually becomes crushed due to simple extrusion, the crushed material is of different sizes, and the utilization rate is low, that is, one of the disadvantages of the existing jaw crusher is that due to the splitting only by the compression force, The crushing efficiency is low, which needs to increase the power of the engine
