RU230912U1 - FEED GRINDER-MIXER - Google Patents

Abstract

The utility model relates to mechanical engineering for animal husbandry and forage production, in particular to feed choppers and mixers. The technical result of the utility model is to increase the efficiency of the feed chopping process, as well as to increase the quality of the chopped product, which meets zootechnical requirements. For chopping and mixing, feed (root crops, forage, compound feed, etc.) is loaded into a receiving bin and, under the action of gravity, with the help of guides, the product being chopped is directed to the operating area of chopping and counter-cutting knives with main horizontal and additional vertical blades. Counter-cutting knives with main horizontal and additional vertical blades are fixed on the inner wall of the working chamber housing in such a way that the chopping knife passes between them, facilitating more complete and rapid chopping of the product. Next, the chopped product moves to the lower part of the working chamber, from where it is unloaded as finished feed by a blade thrower, during the rotation of which the feed moves along the surface of the blades from the center to the unloading chamber. The use of counter-cutting knives with main horizontal and additional vertical blades in the chopper-mixer allows to increase the percentage of the content of the sizes of feed slices corresponding to zootechnical requirements.

Description

The utility model relates to mechanical engineering for animal husbandry and feed production, in particular to feed choppers and mixers.

One of the problems with feed grinding in grinders-mixers is to ensure an effective grinding and mixing process to obtain a homogeneous feed mass. However, grinding often produces a low-quality product that does not meet zootechnical requirements.

A device for crushing root crops is known [1], which contains a body, a vertical chamber, two horizontal disks, knives mounted on the upper disk, and a counter-cutter, the working surface of which is installed at an acute angle to the plane of the disk in the direction of its rotation. Catchers are installed in the vertical chamber.

The disadvantage of this device is the impossibility of obtaining slices of root vegetables.

A feed chopper-mixer is known [2], which includes a vertical cutting element placed in the housing, made in the form of a screw thread with cutting edges along its periphery, and a counter-cutting element covering the cutting element. In this case, a screw working element with a tape screw and directions of winding and rotation opposite to the cutting element is used as a counter-cutting element.

The disadvantage of this chopper-mixer is its low functionality and large losses of juice when chopping root crops.

The closest to the declared utility model, selected as a prototype, is a feed chopper-mixer [3], consisting of a working chamber with a receiving bin and an unloading chamber, a thrower placed in it, chopping knives on a shaft and rotary counter-cutting knives on the inner surface of the working chamber.

The disadvantage of this feed chopper-mixer is that it produces a chopped product with a low percentage of feed slice sizes that meet zootechnical requirements.

The technical result of the utility model is an increase in the efficiency of the technological process of grinding feed, as well as an increase in the quality of the ground product, which meets zootechnical requirements.

The use of counter-cutting knives with main horizontal and additional vertical blades in the chopper-mixer allows for increased homogeneity of the chopped feed, producing slices that meet zootechnical requirements.

The specified technical result is achieved by the fact that the feed chopper-mixer contains a working chamber with a receiving hopper, guides, chopping knives on a shaft, an unloading chamber with a blade thrower placed in it in the form of a plate concave in the direction of rotation, and counter-cutting knives on the inner surface of the working chamber are made in the form of main horizontal and additional vertical blades. The blades of the counter-cutting knives are sharpened at an angle of 6-8°, and the distance between them varies depending on the type of animal in width 10 ... 30 mm and thickness 5 ... 10 mm.

A distinctive feature of the claimed device is the presence of a new design element, namely counter-cutting knives with main horizontal and additional vertical blades.

The claimed grinder-mixer is illustrated by drawings:

Fig. 1 - General view of the grinder-mixer.

Fig. 2 - View A.

Fig. 3 - View B.

The chopper-mixer includes a working chamber 1 with a receiving hopper 2, chopping knives 3 on a shaft 4, guides 5, counter-cutting knives with main horizontal blades 6 and additional vertical blades 7 on the inner surface of the working chamber 1 and a discharge chamber 8 with a blade thrower 9 located in it.

The feed chopper-mixer works as follows:

Before loading the feed, the electric motor of the chopper-mixer is started to set the rotor to the required rotation speed. For chopping and mixing, the feed (root crops, forage, compound feed, etc.) is loaded into the receiving hopper 2 and, under the action of gravity, with the help of guides 5, the product being chopped is directed to the operating area of the chopping knives 3 and counter-cutting knives with the main horizontal 6 and additional vertical 7 blades. The counter-cutting knives with the main horizontal and additional vertical blades are fixed on the inner wall of the working chamber housing in such a way that the chopping knife passes between them, facilitating a more complete and rapid chopping of the product. Next, the crushed product moves to the lower part of the working chamber 1, from where it is unloaded as finished feed by a blade thrower 9, during the rotation of which the feed moves along the surface of the blades from the center to the unloading chamber 8. The use of counter-cutting knives with main horizontal and additional vertical blades in the chopper-mixer allows increasing the percentage of the content of the sizes of feed slices that meet zootechnical requirements.
