Description

(54) HAMMER CRUSHER

one

The invention relates to a device for crushing material, namely, hammer crushers, and can be applied in the agricultural and other industries.

Known hammer crusher, comprising a housing made in the form of a cochlea, a shaft with hammers, a charging port and a discharge grid with elongated holes.

The closest technical solution to the invention of the known ones is a hammer mill, containing a grinding chamber with a rotor, a loading window and a discharge sieve, formed by a series of parallel plates 2,

The disadvantage of this design is clogging of the sieve in the process of operation and the impossibility of removing foreign bodies from the chamber.

The aim of the invention is to eliminate clogging of the sieve during operation and removal of foreign bodies from the chamber.

This goal is achieved by the fact that in a hammer mill, it contains a grinding chamber with a rotor, loading

the window and the discharge sieve formed by a series of parallel plates, the sieve plates have a series of elastic elements cantilevered in a staggered order, the apex of which is opposite to the direction of rotation of the rotor, and the opposite pairs of elements can be installed with a slope forming a groove.

FIG. 1 - Hammer crusher is shown, general view; in fig. 2 - unloading sieve, plan view; in fig. 3 - type B-B

in fig. 2

The crusher contains a crushing chamber 1 with a rotor 2 mounted inside it. In the upper part of the chamber there is a loading

A window 3, and in the bottom, an discharge sieve 4 is installed, consisting of a series of parallel plates 5 with elastic elements 6 cantileverly fixed to them at an angle arranged in a checkerboard pattern.

Elements 6 are set in such a way

that the apex of the acute angle in the place of their attachment to parallel plates 5 is opposite to the direction of rotation of the rotor 2.

. .

.

-...., tjc.t;: r: -; - -The temporal pairs of elastic elements have a slope to form an elobok 7.

Hammer crusher works as follows: coarse feed of high humidity, which is to be crushed, is loaded through the window 3 into the crushing chamber 1, where it is crushed by the rotor hammers 2 and removed through the sieve 4.

The product, which is piling on the plane of the elastic elements 6, due to their openness and the angle of attachment, directed opposite to the vortex flow, shifts to the periphery and descends from it, as a result of which the sieve self-cleans.

The foreign body that has entered the chamber 1 under the action of the working body of the crusher and due to the inclined installation of the counter pairs of elements 6 enters the groove 7 and, by bending them, penetrates the sieve. After the passage of the body, the elastic elements occupy the same position.
