Abstract

FIELD OF THE INVENTION The invention relates to machinery for livestock and fodder production, in particular to shredder stalk feed. The aim of the invention is to increase the productivity of the shredder and reduce the energy consumption for grinding by increasing the uniformity of the feed due to the more efficient impact of the blades on the material. The grinder contains a frame 1 with a rotating hopper 2, a drive 3, a fixed bottom 4, in the center of which there is a shaft 7 on which blades 8 are fixed, the outer ends rigidly connected to the wall of the bunker 2. On the inner surface of the wall of the bunker 2 are placed the blades 6. When the rotation of the hopper 2, the mass contained in it is sealed by the blades 6. At the same time, the material is caught by the additional blades 8 mounted on the vertical shaft 7, due to the fact that the frequency of rotation of the shaft 7 is equal to the frequency of rotation of the hopper 2, feed and the grinding apparatus is produced synchronously, both by blades 8 of shaft 7 and blades 6. 1 sludge.

Description

The invention relates to mechanical engineering for livestock and feed production, in particular to choppers of stalk feed, and is an improvement of the invention by ed. St. No. 1396999.

The purpose of the invention is to increase the performance of the grinder and reduce energy consumption for the grinding process by increasing the uniformity of the feed by increasing the efficiency of the action of the blades on the material.

The drawing shows a feed chopper, a longitudinal section.

The feed chopper contains a frame 1 with a rotating feed hopper 2, a drive 3, a fixed bottom 4 with a chopping apparatus 5. On the inner surface of the wall of the hopper 2 are blades 6. In the central part of the bottom there is a shaft 7 with additional blades 8, the working surface of which is concave along circles in the direction of rotation of the hopper. The lower end of the shaft is located in a bearing 9 mounted in a fixed bottom, and the upper end is rigidly connected to the blades 8, which in turn are rigidly connected to the side wall of the hopper by the outer ends, and the rotational speed of the shaft 7 with additional blades 8 is equal to the rotational speed of the hopper 2.

The feed chopper operates as follows.

The stalk feed with a grab loader or stacker is loaded into the receiving hopper 2. When the receiving hopper 2 is rotated, the mass inside it is compacted by the blades 6 mounted on the inner surface of the wall of the hopper 2, at the same time the material is captured by additional blades 8 mounted on a vertical shaft 7 due to the fact that the rotational speed of the shaft 7 is equal to the rotational speed of the hopper 2, the feed of the stalk feed to the grinding apparatus is carried out synchronously by both the blades 8 of the shaft 7 and the blades 6 of the hopper 2 with a constant density over the entire volume of the hopper, regardless of the thickness of the layer.

The use of the proposed grinder made it possible to increase its productivity and reduce energy consumption for the grinding process.

Claims (2)
