Description

The invention relates to agriculture, in particular to feed mixers.

A known mixer [1], including a casing with a multi-start screw located in it with alternating winding breaks and a reflector mounted above the screw, is made in the form of plates, each of which is located at an acute angle in the longitudinal axis of the screw, the apex of which is turned in the direction opposite to the direction of movement stern.

The disadvantage of this device is the low quality of feed mixing and the inability to mix in certain proportions of the individual components of the feed.

The purpose of the invention is improving the quality of feed and dosing of feed components.

This goal is achieved by the fact that at the opposite ends of the casing establish a loading hopper and an unloading window. The loading hopper is divided into sections by vertical partitions. At the bottom of the sections, dispensers are installed. At the ends of the turns of the screw, parallel to its axis and symmetrically relative to it, rods are installed. Inside the casing, along the outer surface of the screw, a spiral screw is installed, and the screw and spiral screw are provided with separate drives with adjustable rotational speeds.

The drawing shows a General view of the feed mixer.

The feed mixer includes a casing 1 with a horizontal screw 2 placed in it with alternating breaks of winding 3. At the opposite ends of the casing 1 there is a loading hopper 4 and an unloading window 5. The loading hopper 4 is divided into sections by vertical partitions 6. At the bottom of the sections, dispensers 7, which can be made, for example, in the form of dampers. At the ends of the turns of the screw 2, rods 8 are installed parallel to its axis and symmetrically relative to it. Inside the casing 1, along the outer surface of the screw 2, a spiral screw 9 is installed. The screw 2 and the spiral screw 9 are equipped with separate drives 10 and 11, the rotation speeds of which can be adjusted, for example, with the help of variators.

The mixer operates as follows. The feed components are fed separately to the section of the feed hopper 4, from where they enter the internal cavity of the casing 1. The required ratio of the components entering the casing is set using the dispensers 7. Further, the feed components are captured by winding the screw 2 and the spiral screw 9, which rotates between the casing 1 and a screw 2 along the rods 8 mounted on the ends of the turns of the screw 2 parallel to its axis and symmetrically relative to it. The rods 8 limit the lateral movement of the spiral screw 9. When rotating at different frequencies of the screw 2 with the rods 8 and spiral screw 9 installed on it, the feed components are intensively mixed and simultaneously moved to the discharge window 5.

Improving the quality of feed mixing is achieved by the fact that the components of the feed randomly move between the winding of the screw with the rods installed on the ends of the turns of the screw and the spiral screw. Due to the rotation with different frequencies of the screw and spiral screw, intensive mixing of the feed components occurs while they are simultaneously moving from the loading hopper to the discharge window, thereby improving the quality of the resulting mixture.

Dividing the loading hopper into sections with vertical partitions allows feeding individual feed components into the sections, each of which can be included in the mixture in a certain proportion, specified using the batchers installed in the lower part of the sections.
