Description

Lining plate for impact crusher

Technical Field

The utility model relates to a breaker accessory technical field specifically is a welt for impact crusher.

Background

The impact crusher is also called as impact crushing, is mainly used for processing materials which often need to be moved in metallurgy, chemical industry, building materials, water and electricity and the like, is particularly used for processing flowable stone materials in expressways, railways, water and electricity engineering and the like, and can adopt various configuration forms according to the types and scales of processing raw materials and different requirements of finished materials.

The inside of impact crusher is covered with the welt, at the during operation, the welt is beaten to broken material, reach the purpose of protection impact crusher inner wall, however, because the welt is beaten by the material for a long time, wearing and tearing are comparatively serious, belong to vulnerable part, need change after wearing and tearing are serious, and the welt adopts the bolt fastening to be at impact crusher's inner wall usually, through seting up recess and through-hole on the surface at the welt, make the bolt run through the through-hole, the head of bolt is located the inside of recess, reduce the destruction of material to the bolt, but, current impact crusher uses the welt, when using, there is following shortcoming:

the head of the bolt is located in the groove on the lining plate and does not protrude out of the surface of the lining plate, so that damage to the head of the bolt by materials is reduced, but the head of the bolt does not have protection measures, the head of the bolt can still be hit by the materials with small particle sizes, the bolt is damaged, the bolt is broken, and the lining plate falls or the head of the bolt deforms, so that the problem of inconvenient disassembly is solved.

SUMMERY OF THE UTILITY MODEL

The utility model aims at providing a welt for impact crusher for, the bolt that is used for solving fixed welt does not have safeguard measure, is easily by the technical problem who is destroyed by the material.

The above utility model discloses an above-mentioned utility model purpose can realize through following technical scheme:

the utility model provides a welt for impact crusher, includes the welt, the spout has been seted up at the back of welt, the welt is through setting up spout and slider sliding connection at its back, one side fixedly connected with lug of slider, one side fixedly connected with screw rod of slider is kept away from to the lug, the surface threaded connection of screw rod has the nut.

The utility model discloses further set up to: the lug is in sliding connection with a sliding groove arranged on the back of the lining plate.

Through adopting above-mentioned technical scheme, the lug fills the space between slider and the spout, realizes seamless laminating.

The utility model discloses further set up to: the lining plate is connected with the filling block in a sliding mode through a sliding groove formed in the back face of the lining plate.

Through adopting above-mentioned technical scheme, the filling block fills the spout, avoids having the existence of empty drum in the welt.

The utility model discloses further set up to: the front of the lining plate is fixedly connected with a ladder platform block.

Through adopting above-mentioned technical scheme, the top surface of step piece is less than ground to the counterattack formula breaker is at the during operation, and the material strikes back on the welt, and the top surface and the material contact of step piece, area of contact is little, improves and smashes the probability with the material, and reaches the purpose of protection welt, has prolonged the life of welt.

The utility model discloses further set up to: the quantity of terraced platform piece is a plurality of, and a plurality of terraced platform piece is covered with the front of welt.

To sum up, the utility model discloses a beneficial technological effect does:

1. according to the lining plate for the impact crusher, the sliding block, the convex block and the screw form a bolt, the sliding block and the convex block are connected in the sliding groove in a sliding manner by arranging the sliding groove on the back surface of the lining plate, so that when the impact crusher works, materials cannot contact the sliding block and cannot be damaged by the materials, and the problem that the lining plate is difficult to drop or disassemble is solved;

2. according to the lining plate for the impact crusher, the sliding groove is filled by arranging the sliding block, the convex block and the filling block, so that the problem that the lining plate is crushed by materials due to hollowing existing in the lining plate when the impact crusher works is solved, the structure is firm, and the practicability is improved;

3. this welt for impact crusher, through being covered with the trapezoidal piece in the front of welt, the material strikes back on the welt, the top surface and the material contact of trapezoidal piece, area of contact is little, improves the probability of smashing the material to reach the purpose of protection welt, prolonged the life of welt.
