Abstract

The utility model relates to the field of agriculture. A forage crusher is proposed, which contains a loading cylindrical rotating hopper open from above, inside which guide bars with blades are fixed, ensuring a uniform supply of material to the grinding zone, while the hopper is installed on a fixed bottom, in which two supply windows are made, each of which is mounted counter combs. Hammer rotors with hammers are installed under the supply windows, which are mounted with the possibility of their flight above the supply windows, the hammer rotors at the ends of the hammers are covered by pivotally suspended and spring-loaded decks, equipped with shaking devices for cleaning sticky feed particles. The device ensures the quality of the finished product. 2 ill.

Description

The utility model relates to devices for crushing materials, namely to hammer crushers, and can be used in the agricultural, forestry and construction industries.

Known feed crusher, which contains a hopper, a bottom with feed windows, two rotating rotors with hammers flying over the feed windows, a transport device [1].

This design has a low productivity, since when loading the feed, the product hangs on the walls of a stationary hopper, and a uniform supply of material to the rotors is impossible.

The closest technical solution to the utility model is a feed crusher, a vertical rotating loading hopper, a bottom with feed windows and shearing combs, under which horizontal rotors are located one against the other with the possibility of hammers flying over the bottom, covered by spring-loaded corrugated decks. [2].

The disadvantage of this crusher is the lack of reliability of the work process and the quality of the finished product due to sticking of the corrugated deck.

The purpose of the utility model is to improve the quality of the finished product by cleaning the deck using eccentric cams.

This goal is achieved by the fact that in the crusher for feed, containing a working chamber with parallel horizontal rotors located one against the other and a hopper mounted for rotation, the bottom of which is made in the form of two oppositely located segments, between which feeding windows are formed above the rotors by means of transverse plates , in which corrugated decks made in the form of combs are installed, the latter are equipped with eccentric cams.

In FIG. 1 shows a feed crusher, general view, fig. 2 - view A in Fig. 1.

The feed crusher has a loading cylindrical rotating hopper 1 open from above. The drive of the hopper 1 is carried out, for example, by a hydraulic motor through the drive wheel 2. Inside the hopper 1, guide bars 3 with blades 4 are fixed for a more uniform supply of material to the grinding zone. Hopper 1 is installed on a fixed bottom 5, in which two supply windows 6 are made. In each window, counter combs 7 are mounted. e.g. from an electric motor. The rotors 8 at the ends of the hammers 9 are covered by hinged and spring-loaded decks 10, equipped with eccentric cams 11 for cleaning particles of stuck feed. To remove the crushed feed, a transporting device 12 is mounted.

The operation of the feed crusher is carried out as follows.

Roughage of any kind and condition is fed, for example, by a clamshell gripper, into a hopper 1 rotating on a stationary bottom, driven, for example, through a wheel 2. With the help of guide bars 3 and blades 4 of the rotating hopper 1, the loaded feed is fed to the feeding windows 6. Next, the feed moves to the shearing combs 7 directly into the rotation zones of the hammers 9 flying over the supply windows 6 and, when interacting with the spring-loaded decks 10, is crushed to the specified sizes, while the ability of the decks to respond to the volume and density of the feed, for example, deviate in the event of a large piece of material, allows you to maintain the uniformity of the crusher. At the same time, the presence of eccentric cams 11 in spring-loaded decks 10 makes it possible to eliminate clogging of the riffles with wet food. The conveyor 12 displays the crushed material for further processing.

The use of the proposed utility model makes it possible to increase the reliability of the workflow and, accordingly, the quality of the finished product.
