Two-way operation grate-cleaning crusher

Abstract

The invention relates to a two-way operation grate-cleaning crusher; a crushing transmission mechanism can be used for driving a two-way crush roller mechanism to move in the positive direction and the negative direction; the two-way crush roller mechanism comprises a roller body, two-way crush tooth holders and crush teeth; the roller body is provided with the plurality of two-way crush tooth holders; the outer end of each two-way crush tooth holder is symmetrically provided with two crush teeth; a bridge-type structure is adopted by a stand; the stand comprises an end beam and two intermediate beams; the two intermediate beams are respectively arranged at the two sides of the roller body, and are respectively provided with a shearing mechanism which comprises a shear knife; the positions of the shear knives correspond to those of the two-way crush tooth holders; and a shearing pair is formed by the shearing mechanisms and the two-way crush tooth holders. The two-way operation grate-cleaning crusher has the functions of two-way crush cleaning and efficient shearing, can automatically lubricate, prevents the accident caused by deorbit of equipment, can be used for efficiently cleaning all residues on a screening grate, and is reasonable in structure, high in reliability, simple in use, simple and convenient to maintain and long in service life.

Description

technical field [0001] The invention relates to an auxiliary equipment used in screening systems in the fields of thermal power, metallurgy, ports and petrochemical industries, in particular to a two-way working grate crusher. Background technique [0002] Usually, in enterprises that use large amounts of coal or petroleum coke in the electric power, metallurgy, port and petrochemical industries, the coal or petroleum coke transported into the factory by means of transportation such as automobiles and grab cranes must be screened once with a sieving grate. There are often large lumps of coal, frozen coal, coal gangue, petroleum coke or iron ore, straw ropes, woven bags, etc. remaining on the sieving grate. In the past, the sieve grates were cleaned manually, which was labor-intensive and the environment was harsh, and dust and the like could easily cause huge damage to the health of workers. All kinds of grate crushers (also known as grate crushers, mobile crushers or dredg...

AI Technical Summary

Problems solved by technology

However, the integrated pin gear and steel wheel structure either adds an obstacle to the screen grate to hinder the falling of materials (the pitch circle of the pin gear is equal to the outer diameter of the steel wheel); The inconsistency of the radial speed (the pitch circle of the pin gear and the outer diameter of the steel wheel is not equal) causes the steel wheel and the rail to slide relative to each other, which adds a resistance to the walking of the equipment, the actual effect is not ideal, and energy is wasted

[0005] Although most of the current cleaning grate crushers use the hand-operated mechanism to solve the situation that the related machines cannot be used normally due to abnormal shutdowns, etc., it includes multiple bearing seats, steering gear boxes, connecting shafts, hand-operated shafts and handles. complex and wasteful of material

Most of the existing cleaning grate crushers do not have automatic lubrication systems and anti-lifting devices. Manual lubrication is used for the bearings and chain transmission parts that need to be lubricated. Failure brings great loss

Since the cleaning grate crusher and similar equipment use the rotation of the crushing roller to impact, crush and squeeze the large coal, frozen coal, coal gangue or large petroleum coke that need to be crushed, so the corresponding materials will have a certain impact on the equipment. Huge reaction force, especially when encountering hard-to-break or unbreakable objects such as stones and iron blocks, will generate huge reaction force, causing the equipment to lift and the steel wheel to fall off the track. The equipment is hoisted back to the original position, which not only delays the work but also requires a lot of money for maintenance, which greatly increases the maintenance cost of the equipment
