Description

The utility model relates to the field of agriculture, in particular, is used for grinding meat and bone raw materials in the preparation of meat and bone meal.

A device is known [German Patent B 02С 4/8, DT 2158868 СЗ dated 11/27/1971], where two stages of crushing are realized. According to this patent, the rolls are located in perpendicular planes, the device is at least 4-5 times the diameter of the rolls and is not intended for the processing of dimensional materials.

Known technical solution [A.S. USSR №939069, 04.01.1980], where the grinding rolls are also located one under the other and have different sizes of teeth in pitch and height. But this device is intended for processing bulk materials and cannot be used for processing dimensional objects, such as animal carcasses.

Known roller crusher [A. USSR №939068 from 10.22.1979], where the rolls are made up of sections in which the longitudinal ribs of different heights and are installed with different pitch. This allows you to get a smaller fraction when applying the already received mass on the section with a larger step. Selective processing of materials on various sections is possible, but this crusher is intended for processing logging waste into lumpy mass and cannot be used for other purposes in its design features, since the moment transfer to the driven roll is due to the engagement of the driving roll knives, and therefore, the rotational speeds of the rolls are always the same, whereas friction is necessary for efficient grinding work, i.e. the difference in the speeds of rotation of the rolls. As experience shows, the smaller the size of the mass to be used (crumb, powder) is needed, the greater the friction should be, and disk roll crushers allow this to be realized.

Known shredder with rollers having different parameters of the disks [US Pat. RF No. 2 492 927, IPC B02C 4/30 Schröder / applicant and patentee: Smerdov Viktor Vasilyevich and Smerdov Maxim Viktorovich - No. 2011124730/13, decl .: 16.06.2011, publ. 09/20/2013 Bull. No. 26], in which to combine several stages of crushing disks with the same parameters section by section placed on each roll.

The disadvantage of the shredder is the low productivity due to the probability of sticking of large-sized raw materials.

The closest in technical essence and the achieved effect is the crusher animal carcasses DP-30 [http://utilbio.ru/catalog/drobilka-tush-zhivotnih-dp30.html], which includes a housing with a loading and unloading neck, horizontal shaft grinder with rotating blades mounted on it, the cutting edges of which form a discontinuous helix, with fixed knives mounted on the cylindrical housing between the rotating blades, and the shaft with the blades is driven by an electric motor.

The disadvantages of this crusher is the poor capture of meat and bone raw materials with knives and the difficulty of sharpening them. Raw materials can get stuck on fixed knives, which greatly reduces the performance of this crusher.

Therefore, to eliminate these shortcomings, knives should have a number of features:

1. Have a sufficiently large working surface to capture large-sized raw materials (cattle carcass) without slipping.

2. To have a sufficient radius of the base in order to cover the space between the shafts, thereby preventing the crumbling of unground raw materials.

3. At the same time, the above parameters should be selected in such a way as to exclude the possibility of the knives clinging to the adjacent shaft. Otherwise, you will have to increase the overall dimensions of the crusher itself, which will lead to an increase in the cost of construction due to a strong increase in material consumption.

The technical task of the utility model is to increase productivity by eliminating the likelihood of sticking of raw materials, as well as to increase the reliability and efficiency of the crusher.

The technical problem of the utility model is achieved by the fact that in the crusher of animal carcasses, including a body with loading and unloading necks, having fixed knives, a horizontal driven shaft and installed on it with the possibility of rotating a number of knives, a new one is that between a number of knives, installed in the possibility of rotation, an additional row of knives is placed with the possibility of counter-rotation, the cutting edge of which is sharply sharpened, and the shaft on which they are mounted is in contact through the cylindrical gear with a horizontal shaft of another row of knives, while the cutting edges are spaced apart by an angle of 60 ^o .

The technical result of the utility model is to increase productivity by eliminating the likelihood of sticking of raw materials, as well as increasing the reliability and efficiency of the crusher.

Figure 1 shows the three-dimensional model of the proposed crusher animal carcasses; figure 2 - arrangement of shafts and knives; figure 3 - General view of the crusher animal carcasses.

Crusher animal carcasses (figure 1) consists of a housing 1 placed on the frame 2 with the boot 3 and the discharge (not shown) neck. In the case there are installed leading 4 and driven 5 horizontal hexagonal shafts, with knives 7 and 6 alternately worn on them, between which limiters 8 are installed. At the same time, the cutting edge of knives 7 has a sharp sharpening

The cutting edges of the knives 6 and 7 are separated by an angle of 60 ⁰ (figure 2).

Lead 4 and slave 5 horizontal hexagonal shafts of knives 7, 6 are installed with the possibility of counter-rotation relative to each other. To transfer the rotation from the drive shaft 4 to the slave 5 serves a cylindrical gear 9 (figure 3).

On the inner surface of the housing 1 between the knives mounted fixed knives 10.

The drive of the drive shaft 4 includes an electric motor 11 and a gearbox 12.

Crusher animal carcasses works as follows.

From the electric motor 11 through the gearbox 12, the rotation is transmitted first to the driving shaft 4 with the blades 7, and then through the cylindrical gear 9 to the driven shaft 5 with the blades 6 rotating in the opposite direction relative to the driving shaft 4. The raw material, for example, animal carcass, enters the loading neck 3 knives 6 and 7 rotating towards each other, alternately installed and separated by limiters 8, where it is caught by knife 6, and then interacting with the sharp edge of knife 7 is cut and crushed together m the action of the knives 6 and 7, while moving down into the discharge opening (not shown).

The proposed design crusher animal carcasses has the following advantages:

- placement between a number of knives installed with the possibility of rotation, an additional row of knives with the possibility of counter-rotation, the cutting edge of which has a sharp sharpening allows for efficient grinding of large-sized raw materials by cutting it, which reduces the resistance to movement through the grinding zone, which improves productivity and reliability by eliminating the possibility of sticking of raw materials;

- placement of knives, cutting edges of which are spaced apart by an angle of 60 ⁰ , on the shafts that are in contact with each other through a cylindrical gear transmission allows you to increase the efficiency of the crusher.
