Description

The invention relates to a device for grinding feed. The goal is to increase the efficiency of the separation process. Set2

The device consists of a crusher body 1 with a hopper 5 connected by pipe 6 to a separation chamber 8, at the entrance of which a package of 9 parallel plates arranged perforated with openings exceeding the maximum size of crushed feeds is installed. At the same time, the possibility of turning the package allows you to change the amount of resistance to the air flow acting on the feed, depending on its physical and mechanical properties. The hinge mounting plates with the possibility of their free movement under the action of its own weight ensures their constant orientation relative to the direction of the air flow. 1 il.

The invention relates to a device for grinding feed, can be applied in agricultural and other industries and is an improvement of the invention according to ed. St. No. 959681.

The purpose of the invention is to increase the efficiency of the separation process.

The drawing shows a device for grinding feed, General view.

The device comprises a crusher body 1, inside which a corrugated deck 2 and a crushing rotor 3 with hammers 4 are fixed. A hopper 5 is installed above the crusher. The case 1 is equipped with a discharge pipe 6 and a return channel 7 connected to the separation chamber 8. At the entrance of the latter in its upper part opposite the holes of the discharge pipe 6 is installed package 9 parallel located in it across the direction of flow of the vertical plates, which are perforated with the size of their holes exceeding the maxi the maximum particle size of the crushed feed. Fixing the package 9 on a common frame 10 pivotally connected to the housing allows changing the position of the entire package relative to the vertical plane. In addition, each plate, package 9 has a hinge, located above its center of gravity, which ensures their free movement under the action of its own weight when turning the package. Under the package of plates mounted rotary valve 11, forming with the lower edges of the plates receiving hopper 12 for the selection of the crushed feed, in the lower part of which is installed the discharge auger 13.

The device works as follows.

The feed to be crushed, for example grain, from the hopper 5 is fed by gravity into the housing 1, where it is crushed by hammers 4 of the crushing rotor 3 and guided along the discharge pipeline 6 to the separation chamber 8.

5 A pack of 9 plates installed in the chamber gradually quenches the speed of the flow passing through the openings of the plates, as a result of which particles of crushed feed with different windage and weight will fall in different places throughout the depth of the pack. By changing the position of the plate pack by turning it in the hinge, they are shifted relative to the orifice of the injection pipe 6, as a result of which the resistance to airflow changes. When you rotate the package, each plate is in a vertical position. Smoothly changing the position of the package 9 and the valve 11, set them to the appropriate degree of 20 grinding, depending on the physical and mechanical properties of the feed. When this fraction falling before the valve 11, is sent to the return channel 7 for regrinding, and the fraction that got into the receiving funnel 12, with the help of the auger 13 is given for
