Detailed Description

Referring to fig. 1-2, a crusher for construction comprises a crushing box 10, four legs 11 fixed to the lower end of the crushing box 10, two crushing rolls provided therein: a left crushing roller 20 and a right crushing roller 30, and a plurality of crushing teeth 21 are fixed on the outer surfaces of the two crushing rollers.

The upper part of the crushing box 10 is provided with a feed inlet 13, the lower part thereof is provided with a fine material outlet 18, and the side part thereof is provided with a coarse material outlet 15.

A supporting beam 16 is fixed on the front side and the rear side of the crushing box 10, two ends of a left crushing roller 20 are connected to the supporting beam 16 through a left bearing respectively, two ends (see reference numeral 31) of a right crushing roller 30 are fixed on an inner ring of a right bearing 33 respectively, an outer ring of the right bearing 33 is fixed on a sliding block 35, the sliding block 35 is arranged in a horizontal groove 36 of the supporting beam 16, the sliding block 35 can slide along the horizontal groove 36, and a pressure spring 37 is arranged between the right side surface of the sliding block 35 and the supporting beam 16.

The outer surface of the left box wall of the crushing box 10 is fixed with a support plate 12, a motor 22 is fixed on the support plate 12, the motor 22 is connected with the end part of the left crushing roller 20, and the motor 22 provides driving power for the left crushing roller 20.

Be equipped with sieve 40 in broken case 10, sieve 40 is located the below of crushing roller, the one end of sieve 40 articulates on the inboard tank wall of broken case 10 (see reference numeral 41), the opposite side stretches out from coarse fodder export 15 and forms extension plate 401, the whole slope of sieve 40 sets up, the left side is high, the right side is low, the fixed spring board 43 of right tank wall surface of broken case 10, the lower surface of sieve 40 and the broken case tank wall contactless of 15 departments of coarse fodder export, sieve pressure spring 42 between extension plate 401's lower surface and the spring board 43.

In this patent, only for left crushing roller 20 connect the drive assembly, for making the better rotation of right crushing roller 30, right crushing roller 3 is less than left crushing roller 20, and the left surface of feed inlet 13 extends to crushing case 10 inside and forms feed plate 131, and the lower extreme of feed plate 131 is the slope of left crushing roller 20.

As shown in fig. 1, the feed inlet 13 is a trumpet shape with a large top and a small bottom for the convenience of feeding.

The working principle is as follows:

when the crushing is needed, the motor 20 drives the left crushing roller 20 to rotate clockwise, referring to fig. 3, the material 90 slides along the feeding plate 131, and after contacting the left crushing roller 20 (referring to reference numeral 91), the material will rotate clockwise along the left crushing roller 20, and after contacting the right crushing roller 30 (referring to reference numeral 92), the material will enter the crushing area (referring to reference numeral 93) along the gap between the left crushing roller 20 and the right crushing roller 30, so as to complete the crushing.

When the material contacts the right crushing roller 30 (see reference numeral 92), because the position of the right crushing roller 30 is lower, the material itself carries more kinetic energy to be transmitted to the right crushing roller 30 (if the two crushing rollers are horizontal, the kinetic energy should be transmitted to the two crushing rollers averagely), so that the right crushing roller 30 can obtain more energy from the material to increase the speed of the counterclockwise rotation of the material, and the crushing is convenient.

If the material is hard, the right crushing roller 30 and the sliding block 35 move backwards together in the horizontal groove 36, so that the gap between the two crushing rollers is enlarged to enable the material to pass through, and the material is prevented from being damaged by the crushing roller (or the motor). After the hard material passes through, the right crushing roller 30 is reset by the pressure spring 37.

As shown in figure 1, the materials which are broken fall on the sieve plate 40, the fine materials are discharged from the fine material outlet 18 below, the coarse material (the materials which cannot meet the requirement are along) sieve plate 40 slides rightwards and flows out from the coarse material outlet 15, in the process, the sieve plate 40 can vibrate to accelerate the sieving operation due to the vibration of the motor 22, and the sieve plate pressure spring 42 can reduce the impact of the sieve plate 40 on the wall of the crushing box at the coarse material outlet 15 and prolong the service life of the crushing box.

See the prior art for additional details.

While the preferred embodiments of the present invention have been described, it will be understood by those skilled in the art that various changes and modifications may be made without departing from the general inventive concept, and it is intended to cover all such changes and modifications as fall within the true spirit and scope of the invention.
