Abstract

FIELD: agriculture.

SUBSTANCE: device comprises hummer crusher and cutting machine whose cylindrical housings are interconnected through the passage. The sides of the passage are made of two parts. One of the parts is secured to the cylindrical housing of the hummer crusher, and the other part is secured to the cylindrical housing of the cutting machine for permitting rotation around their axis and movement one with respect to the other. Each of the cylindrical housings is mounted for permitting rotation around its axis clockwise or counterclockwise.

EFFECT: reduced power consumption.

Description

The invention relates to agricultural production, in particular to devices for grinding feed.

Known feed chopper containing a hammer mill and a cutting machine, the cylindrical body of which is communicated with each other by the channel / RU 1634171 A1, 03/15/1991 /.

In this design of the grinder, the contact angle of the front wall of the channel with the generatrix of the hammer mill body is constant. It is known that the speed of impact of the hammer in the working chamber of the crusher on the material has a significant impact on the energy intensity of the process, grinding time, and grinding module. An increase in the speed of hammers leads to a decrease in the specific energy consumption. Therefore, all hammer crushers operate at a peripheral speed of hammers of 70-95 m / s. However, a further increase in the speed of the hammers also leads to an increase in ventilation losses. Therefore, it is necessary to increase the collision velocity of the particles of the crushed material and the hammers of the crusher. Also, the speed of collision will affect the particle size of the resulting product. It is known that different types of animals need their own grinding material. To achieve this in the existing design of the grinder is not possible. Since the rotational speed of the rotors of the cutting machine and hammer mill is constant, the angle of entry of the pre-ground material from the cutting machine into the crushing chamber is also constant.

This task is achieved in a feed mill containing a hammer mill and a cutting machine, the cylindrical bodies of which are communicated with each other by the channel, while the side walls of the channel are made of two parts, one of which is mounted on the cylindrical body of the hammer mill, and the other part on the cylindrical body of the cutting machines with the possibility of rotation around the axis of their attachment and movement relative to each other, while each cylindrical body is mounted with the possibility of rotation around its axis along or prot in the clockwise direction to change the angle of the channel walls with coupling housings hammermill and cutting machine.

Figure 1 shows a General view of a universal feed chopper.

In Fig.2 - the same (option).

Figure 3 is the same (option).

The feed chopper consists of a hammer mill 1 and a cutting machine 2 mounted on a frame 3. The cutting machine and the feed mill are connected via a channel 4, the walls 5 of which consist of two parts, one part belongs to the hammer mill and the second to the cutting machine. Moreover, the walls belonging to both the hammer mill and the cutting machine can be located both outside and inside the channel. The proposed design of the grinder provides the ability to rotate the cylindrical body of the hammer mill or cutting machine around its axis.

The walls of the channel have a separate attachment to each cylindrical body of both the hammer mill and the cutting machine. In this case, the side walls of the channel have the ability to rotate around the axis of attachment to the cylindrical body and move relative to each other in the horizontal plane. By turning a cylindrical body, for example, a hammer mill, clockwise or counterclockwise, we achieve a change in the angle of the channel with the cylindrical bodies of the hammer mill and cutting machine. Thereby, the angle of entry of the pre-ground material from the cutting machine into the crushing chamber also changes. This will allow you to change the collision speed of the particles of the crushed material and the hammers of the crusher, which in turn will allow you to get a different grinding of the crushed product and reduce the cost of grinding the material.
