Description

Technical Field

[0001] The invention relates to the field of crushers, in particular to an anti-falling wear-resistant part for crushers. Background Art

[0002] As an engineering tool, crusher is the main equipment used in mining, mainly for crushing stones of different sizes.

[0003] When the machine is working, driven by the motor, the rotor rotates at high speed. When the material enters the plate hammer action area, it collides with the wear-resistant hammer head on the rotor and is crushed.

[0004] However, this wear-resistant hammer head is connected to the hammer disc through a pin hole. Although it is easy to replace, the hammer head is easy to loosen during operation and fall off. The impact of falling stone will also cause wear on the crushing components and reduce the efficiency of the crusher in crushing stones. Summary of the invention

[0005] The object of the present invention is to provide a wear-resistant part for a crusher that prevents it from falling off, so as to solve the problems raised in the above-mentioned background technology.

[0006] To achieve the above-mentioned purpose, the present invention provides the following technical scheme: a wear-resistant part for a crusher to prevent falling off, comprising: a crusher; a rotating shaft is rotatably connected inside the side wall of the crusher, and the rotating shaft is fixedly connected to a driving shaft at one end of the crusher, and the front and rear ends of the driving shaft are both threadedly connected with positioning bolts from the outside to the inside, and the outer wall of the driving shaft is sleeved with a wear-resistant ring, and the wear-resistant ring is movably connected to a wear-resistant disk 1 and a wear-resistant disk 2 at one end of the driving shaft, and the back side of the wear-resistant disk 1 is movably connected to the front side of the wear-resistant disk 2, and high-strength screws are inserted at the matching parts of the wear-resistant disk 1 and the wear-resistant disk 2, and high-strength nuts are threadedly connected at both ends of the high-strength screw, and a high-strength spring is sleeved on the outer wall of the high-strength screw, and the edges of the opposite surfaces of the wear-resistant disk 1 and the wear-resistant disk 2 are inserted with The embedded part has a V-shaped wear-resistant hammer head fixedly connected to one end of the wear-resistant disk 1 and the wear-resistant disk 2. By connecting the V-shaped wear-resistant hammer head to the embedded part, the V-shaped wear-resistant hammer head can be embedded in the hammer disk composed of the wear-resistant disk 1 and the wear-resistant disk 2 through the embedded part. The wear-resistant disk 1 and the wear-resistant disk 2 are assembled by simply inserting the high-strength screw, sleeved with the high-strength spring and arranged in the opposite surfaces of the wear-resistant disk 1 and the wear-resistant disk 2, and the high-strength nut is screwed in to compress the wear-resistant disk 1 and the wear-resistant disk 2. The high-strength spring shrinks to the extreme, and the wear-resistant disk 1 and the wear-resistant disk 2 are combined into a hammer disk. The embedded design makes the combination of the hammer head and the hammer disk more firm, avoids the detachment of the hammer head when crushing stones, solves the problem of frequent replacement of the hammer head during use, and the V-shaped head at the bottom of the wear-resistant hammer head greatly improves the crushing effect.

[0007] As a further solution of the present invention: the matching parts of the embedded part, wear-resistant disk 1 and wear-resistant disk 2 are all provided with fixing holes, and the internal threads of the fixing holes are connected with fixing bolts. After the hammer head is embedded in the hammer disk, the insertion of the fixing bolts can further enhance the connection firmness, prevent the hammer head from falling off during high-speed operation, and improve the stone crushing efficiency.

[0008] As a further solution of the present invention: a gear is fixedly connected to the end of the rotating shaft, and a servo motor is fixedly connected to the front end of the rotating shaft on the right side. The two sets of gears are meshed, and under the drive of the servo motor, a strong rotational force is provided for the crushing assembly. The left and right sets of crushing assemblies in the crusher crush the incoming stone.

[0009] As a further solution of the present invention: a baffle plate 1 and a baffle plate 2 are respectively fixedly connected to the feed port of the crusher, and the positions of the baffle plate 1 and the baffle plate 2 are symmetrically arranged. The baffle plate 1 and the baffle plate 2 are arranged at the feed end of the crusher, which can not only transfer the stone into the crushing assembly for crushing, but also prevent the stone from splashing out during crushing, thereby improving the safety of operation.

[0010] As a further solution of the present invention: a fixed plate is fixedly connected to the bottom of the crusher, and the fixed plate is movably connected to a support base at one end of the crusher. The support base not only provides support for the crusher, but also serves the purpose of shock absorption.

[0011] As a further solution of the present invention: the inner cavity of the support base is fixedly connected with a support plate, the interior of the support plate is movably connected with a shock-absorbing rod, and the outer wall of the shock-absorbing rod is sleeved with a shock-absorbing spring, which can not only eliminate the tangential and radial vibrations and twisting forces generated by the crushing assembly during the operation of the crusher, but also reduce the vibrations caused by axial stress, which not only improves the shock-absorbing effect, but also increases the service life of the crushing assembly.

[0012] As a further solution of the present invention: the shock-absorbing rod is movably connected with a shock-absorbing plate at one end of the shock-absorbing spring, and both ends of the shock-absorbing rod are fixedly connected to limiting rings. The shock-absorbing plate can move up and down stably, and can provide stable support for the crusher, fully meet the conditions for normal use of the crusher, improve the shock-absorbing effect of the crusher, and also increase the service life of the crushing assembly.

[0013] As a further solution of the present invention: a buffer groove is provided in the inner cavity of the support base, and a buffer pad 1 and a buffer pad 2 are fixedly connected in the buffer groove respectively. The buffer groove is movably connected to the edge of the shock-absorbing plate. The force buffering effectively reduces the resonance amplitude of the mechanical structure, thereby avoiding structural damage caused by dynamic stress reaching its limit, which helps the crusher to quickly recover to a stable state after being subjected to instantaneous vibration.

The V-shaped wear-resistant hammer head can be embedded in the hammer disc composed of the wear-resistant disc 1 and the wear-resistant disc 2 through the embedded part. The assembly of the wear-resistant disc 1 and the wear-resistant disc 2 only requires the high-strength screw to be inserted, the high-strength spring to be sleeved and the high-strength spring to be arranged in the opposite surfaces of the wear-resistant disc 1 and the wear-resistant disc 2, the high-strength nut is twisted in, the wear-resistant disc 1 and the wear-resistant disc 2 are compressed, the high-strength spring is contracted to the extreme, the wear-resistant disc 1 and the wear-resistant disc 2 are combined into a hammer disc, the embedded design makes the combination of the hammer head and the hammer disc more firm, avoids the separation of the hammer head when crushing stones, solves the problem of frequent replacement of the hammer head during use, and the V-shaped head at the bottom of the wear-resistant hammer head greatly improves the crushing effect;

[0016] 2. Through the arrangement of the embedded parts, the first wear-resistant plate, the second wear-resistant plate, the fixing holes and the fixing bolts, after the hammer head is embedded in the hammer plate, the fixing bolts are inserted, which can further strengthen the connection firmness, prevent the hammer head from falling off during high-speed operation, and improve the stone crushing efficiency.
