Description

The invention relates to agriculture, and in particular to equipment for the preparation of bulk feed in farms.

A well-known line for the production of feed (Patent for utility model RU No. 47627 MPK A23N 17/00. Technological line for the preparation of full feed) consisting of feed bins, batchers, crushers, mixer.

The disadvantage of this line is the bulkiness of the design, high material consumption, as well as the absence of a cleaning device for the separation of large mineral and metal impurities (Clause 6.1.1. NTP-APK 1.10.16.002-03. Norms of technological design of agricultural enterprises for the production of animal feed [Text]: approved by the Ministry of Agriculture of the Russian Federation on December 31, 03; input to the village from January 1, 2004: instead of VNTP 19-86: - M., 2003). In addition, the difficulty is setting up a system of screw feeders when changing the formulation, which does not allow you to effectively respond to changes in the properties of the material, such as humidity, because it is necessary to link the physical and mechanical properties of the material with the working processes of machines (Melnikov S.V. Mechanization and automation of livestock farms. - M .: Kolos, 1978, p. 66).

A known line for the production of animal feed (Patent RU No. 2276568 IPC A23N 17/00. Workshop for the preparation of animal feed), consisting of feed bins, batchers, crushers, mixer.

With the existing preliminary purification from metallomagnetic impurities, the disadvantage of this line is also the bulkiness of the structure and high material consumption. The supply of crushed components is carried out by gravity in turn into the trolley. This leads, firstly, to dusting the air, which is unacceptable in the production of animal feed (Hygienic standards GN 2.2.5.1313-03 of the Ministry of Health of Russia, Moscow, 2003. Table "Maximum permissible concentrations (MPC) of harmful substances in the air of the working zone", p. 1759. Grain dust in the air - 4 mg / m ³ ), and secondly, a transport operation is added to the feed production line, which generally complicates the system.

The closest in its technical essence is the line for the production of animal feed (Patent RU No. 2284860 IPC B02C 13/00. Feed mill), consisting of feed hoppers, batchers, crushers, mixer.

This line is much simpler in design and less material intensive. The disadvantage of this line is the inconsistency in the dosage of grain and mineral components, which leads to a change in the ratio between the components and, accordingly, the formulation. In addition, there is no preliminary cleaning of the material from large mineral and metal impurities.

The technical essence of the claimed invention is to increase the efficiency and quality of the prepared feed.

The present technical essence is achieved by the fact that in the feed production line containing a blockage pit, elevators, auger conveyor, loading hoppers with a slide gate, a vibrating batcher, a hammer mill, a mixer, scales and a storage hopper, a cleaning device is located in the upper part of the blocking pit made in the form of a gable inclined sieve with a rigid system of gable slats on both sides and a filling pit spring-loaded on one side of the wall and connected to a vibration exciter on the other, and w The Iberian flap of the loading hoppers is made in the form of a sector with concentric openings and offset relative to each other by an angle φ formed by tangents extending radially to the opening located at the smallest concentric radius.

Figure 1 is a functional diagram of a line for the production of animal feed (side view).

Figure 2 - cleaning device (top view).

Figure 3 is a view A in figure 2.

Figure 4 - slide gate (top view).

The feed production line consists of a filling pit 1, a noriya 2, a screw conveyor 3 with unloading windows 4, loading bins 5 for unmilled grain components with a vibrating batcher 6, a hammer mill 7, norias 8 and 9, a hopper 10 for crushed grain components and loading hoppers 11 for additives, a slide gate 12 mounted on an axis 14, with holes 13 and a handle 15, a mixer 16 with a shutter 17, weights 18 and a storage hopper 19. In the upper part of the filling pit 1 there is a cleaning device 20 for separating neural and metallic impurities from the source material, made in the form of a gable inclined sieve 21 with a rigid system of gable slats 22, spring-loaded on one side by a spring 23 to the wall of the filling pit 1, and on the other through a cable 24 and block 25 is connected to the vibration exciter 26. Planks 22 made gable toward the sieve 21. The slide gate 12 of the loading bins is made in the form of a sector, and the holes 13 are concentric thereon and offset relative to each other by an angle φ formed by tangent radially extending to the hole located at the smallest concentric radius.

A feed production line operates as follows.

When you turn on the drive of the vibration exciter 26, suspended on a cable 24 passing through the block 25, a rigid system of gable slats 22 of the cleaning device 20 is brought into reciprocal motion, attached on the opposite side by a spring 23 to the wall of the filling pit 1, due to which the material located in blocking pit 1, is sifted through a gable inclined sieve 21, separating large mineral and metal impurities, and enters the elevator 2. Noria 2 lifts the material up to the auger conveyor 3 and then not crushed the components are fed into the loading hoppers 5 through the corresponding open shutters 4. Additives that do not require grinding are moved by the screw 3 into the loading hoppers 11. After starting the elevator 8, the crusher drive 7 is turned on, and then the vibration dispenser 6 with a pre-set output rate of each component and feeds them in the crusher 7, where the material is crushed and mixed, and then through the elevator 8 is loaded into the hopper 10.

In the mixer 16, with the shutter 17 closed, mounted on the scales 18, the components in the required quantity from the bins 10 and 11 are alternately loaded using the slide gate 12, which is rotated around the axis 14 and controlled by the handle 15, while each time the rotation is made through an angle φ and when combining the hole 13 with the outlet in the hopper 10, the remaining hoppers remain closed until the required amount of material, determined by the weights 18, is fed into the mixer 16. Then, we again turn the slide gate by an angle 15 φ until the next hole 13 is combined with the feed hopper 11, until the required quantity of this component is supplied. This continues until all components are fed into the mixer 16. When the shutter 17 is closed, the components are mixed in the mixer 16, and then when it is opened, the mixture is unloaded and fed through the elevator 9 to the storage hopper 19.
