Double-geared roller strong graded crusher capable of adjusting and controlling particle size continuously

Abstract

The invention relates to industrial crushing equipment, in particular to a double-geared roller strong graded crusher capable of adjusting and controlling a particle size continuously. The crusher solves the problems of low degree of automation, high labor intensity, long construction period, high adjustment difficulty and the like of the conventional crusher during the adjustment of the particle size. The crusher comprises a base, a movable bearing block, a static bearing block, a static tooth roller and a movable tooth roller, wherein the movable bearing block is connected with the static bearing block by a pull rod; the static bearing block is locked with the pull rod; the movable bearing block can move to and fro along the pull rod by an adjusting gearbox driven by a hydraulic motor and a worm and worm wheel mechanism; a movable bearing block slide is arranged on the base; a hydraulic locking cylinder is mounted on the base; a compression sliding block which can extrude the movable bearing block is fixed at the front end of the piston rod of the hydraulic locking cylinder; an encoder is mounted in the adjusting gearbox; and a displacement sensor is mounted in the hydraulic locking cylinder and is connected with a programmable logic controller (PLC) control system. The crusher has the advantages of simple structure, simplicity and convenience in operation, short adjustment period, high production efficiency and degree of automation and the like, and can be widely applied to the field of industrial crushing.

Description

technical field [0001] The invention relates to an industrial crushing equipment, in particular to a double-toothed roller powerful grading crusher capable of continuously regulating the particle size. Background technique [0002] At present, there are four ways to adjust the particle size of the powerful grading crusher, but each has its own shortcomings in actual use. The specific analysis is as follows: [0003] 1. The eccentric bearing cup adjusts the granularity. [0004] When adjusting, it is necessary to stop the machine and turn the eccentric bearing cup to adjust the center distance between the two crushing rollers to achieve the purpose of adjusting the particle size. [0005] Disadvantages: After adjustment, it is necessary to add or reduce gaskets on the base of the motor and reducer to meet the changing center height, which is not conducive to ensuring the accuracy of the height direction of the transmission center, directly affects the stability of the high-s...
