Abstract

A device for grinding meat and fish feed, consisting of a fixed cylindrical body resting on a support, inside of which a shaft with fingers and knife elements is located on the bearings, characterized in that the knife elements are mounted on the fingers with the possibility of adjusting the angle of rotation of the knife elements with adjusting nuts, moreover fingers and knife elements are located along a helical line along the shaft.

Description

A device for grinding meat and fish feeds relates to the field of agriculture, namely, devices for grinding meat feeds, fresh and defrosted fish and can be used on animal husbandry and livestock farms and complexes for preparing animal feed.

A device for grinding meat and fish feed - a meat grinder G7-MT2-K15 [1], consisting of a screw, receiving grill, two knives, two knives and a drive mounted in the housing. The principle of operation of the device is as follows: the product loaded into the hopper is fed by a screw to the cutting apparatus, where it is crushed using knives and grids. The degree of grinding of the feed is regulated by a set of interchangeable knife grids with different hole diameters.

The disadvantage of the device for grinding meat and fish feed - meat grinder G7-MT2-K15 is that the resulting degree of grinding feed has strictly defined values, depending on the diameter of the holes of the knives of the grills. On the one hand, this does not allow to obtain optimal values of the degree of grinding for various types of feed, feed is over-crushed or under-crushed, on the other hand, it leads to the need to contain an excessive set of interchangeable knife grids with different hole diameters.

It is also known a device for grinding meat and fish feed - chopper IK-5 [2], consisting of a disk on which knives, blades, grills and drives mounted in the housing are mounted. The principle of operation of the device is as follows: the product is loaded into the device and supplied to a rotating disk, is pressed against the disk by the action of its own weight, and crushed by knives mounted on it. Through the grooves in the disk, it is pressed into the lower chamber and ejected by two blades through the outlet pipe.

The disadvantages of the device for grinding meat and fish feed - chopper IK-5 are: 1) the heterogeneity of the linear dimensions of the resulting particles, due to the fact that the cutting is carried out with the removal of chips, the length of the chips to be cut exceeds the thickness several times; 2) sensitivity to uneven loading, with a small filling of the device, the feed does not have enough weight to press against the disk and grinding does not occur.

The technical result achieved by the proposed device for grinding meat and fish feed is the possibility of obtaining a wide range of sizes of the crushed product. In addition, the linear sizes of the resulting particles are quite uniform, which helps to increase the efficiency of the subsequent processes of preparation of feed for animals, such as dosing, mixing and distribution. The working process of the device is not affected by the uneven loading of the material, grinding occurs at any degree of filling.

A technical result is achieved by means of knife elements mounted on the fingers with the possibility of adjusting the angle of rotation of the knife elements with adjusting nuts, and the fingers and knife elements are located along a helical line along the shaft.

Figure 1 shows a General view of the device for grinding meat and fish feed.

Figure 2 shows the cutting apparatus of the device for grinding meat and fish feed.

A device for grinding meat and fish feed consists of a fixed cylindrical body 1, a prefabricated of two parts. The housing of the device is supported by a support 2. Inside the housing of the bearings 3 there is a shaft 4, pins 5 are mounted in the through holes of the shaft, to which the knife elements are attached 6. The path along which the fingers with the knife elements are mounted represents a helical line. Changing the angle of rotation of the knife elements is carried out by adjusting nuts 7. The output end of the shaft 8 is connected to the drive using a coupling.

A device for grinding meat and fish feed works as follows.

The material to be ground is fed into the loading neck 9 of the device, from which it enters the rotating shaft with knife elements, where it is ground. Knife elements during rotation form a helical surface, facilitating the gradual movement of material along the shaft to the discharge neck 10. As a result, the grinding process proceeds throughout the entire period of the material inside the device.

The degree of grinding and the performance of the device are adjusted by turning the fingers around their axis of rotation by the required angle and fixing them with adjusting nuts. The angle of rotation of the fingers varies over a wide range, with an increase in the angle of rotation, the degree of grinding decreases and the productivity of the device increases. Fingers with knife elements can be installed both with a constant pitch of the angle of rotation of all fingers, and with a variable pitch of the angle of rotation from the loading zone to the unloading zone of the product. The choice of installation method depends on the physico-mechanical properties of the product being ground and the degree of grinding required.
