Detailed Description

In order to make the technical problem, technical solution and advantageous effects to be solved by the present invention more clearly understood, the following description is given in conjunction with the accompanying drawings and embodiments to illustrate the present invention in further detail. It should be understood that the specific embodiments described herein are merely illustrative of the invention and are not intended to limit the invention.

As shown in figure 1, the hammer crusher comprises an upper shell 1, a lower shell 2 and a curved screen body 3 arranged in the lower shell, wherein a plurality of supporting plates 4 are arranged in the lower shell 2, the tops of the supporting plates 4 are provided with curved notches, the two sides of the lower shell 2 are respectively provided with an upper cushion block 5 and a lower cushion block 6, the bottoms of the upper cushion blocks 5 and the tops of the lower cushion blocks 6 are curved, a curved fixing groove 7 is formed by a gap between the upper cushion blocks 5 and the lower cushion blocks 6, the curved fixing groove 7 on one side penetrates through the inner wall of the lower shell to form a curved jack 8, the curved screen body 3 is inserted along the curved jack 8, the end part of the curved screen body is inserted in the curved fixing groove 7 on the other side, the middle part of the curved screen body is supported on the supporting plates 4, strip-shaped limiting blocks 9 are arranged on the two sides of the curved screen body 3, the two ends of the strip-shaped limiting blocks 9 are respectively fixed, the two ends of the arc-shaped baffle plate 10 are respectively fixed on the strip-shaped limiting blocks 9 through bolts, the middle part of the arc-shaped baffle plate 10 is also provided with a pressing plate 11, and the pressing plate 11 is fixed on the lower shell 2 through bolts.

The utility model discloses it is internal that the sieve bend passes through arc jack 8 and inserts the inferior valve, and both sides and the laminating of strip stopper 9 are then fixed the sieve bend through cowl 10, and the sieve bend is installed in the inferior valve casing like this.
