Abstract

FIELD: agriculture. SUBSTANCE: grain grinder has housing accommodating plate-shaped disk. plate is secured on shaft for rotation and is provided with perforations over entire surface. Funnel-shaped branch pipe is installed inside plate coaxially with plate for displacement in vertical plane. Stops are provided from inner side of funnel-shaped branch pipe. End face surfaces of funnel-shaped branch pipe, stops and smaller base of plate are made riffled. Grain to be ground is delivered into space of branch pipe. With plate rotating, grain comes in engagement with riffled surface of plate base and secondary grinding is provided owing to contact of grain with riffled end face surface of branch pipe and stops. EFFECT: increased capacity of grinder owing to increased area of contact of grain and working surface. 2 cl, 5 dwg

Description

 The invention relates to the mechanization of technological processes of agricultural production for use in the livestock industry.

 Known feed chopper, made in the form of a cylindrical body, a rotor with a L-shaped knives and an opposing element. (A.S.SSSR N 793473, MKI A 01 F 29/00).

 The disadvantage of this grinder is its low productivity, due to the limited use of the working surface of grinding, as well as the unsatisfactory degree of grinding of the product.

 Known disk chopper root crops KPI-4, containing a receiving hopper, discharge neck, inner blades, a vertical knife, a thrower, deck, lower disk, upper disk, horizontal knife, emphasis. (B.I. Vagin, V.M. Pobedinsky Projection on mechanization of livestock farms - L. Kolos, 1983. - p. 48, Fig. 11. (prototype).

 The disadvantage of this grinder is the high energy intensity, limited ability to adjust the degree of grinding of the product, which leads to a deterioration in the quality of grinding.

 Improving the performance of the grain grinder and the quality of grinding is achieved by the fact that the grain grinder contains a housing and a disk placed in it, over which stops are installed, the disk being made in the form of a perforated plate with a large base facing the top, and the stops are rigidly connected to the inner surface of the funnel-shaped nozzle, perforated plate placed with the possibility of movement in the vertical plane, and the smaller base of the plate and the end surface of the funnel-shaped nozzle are made corrugated s.

 In FIG. 1 shows a diagram of a grain grinder, general view; in FIG. 2 - working bodies (corrugated base of a perforated plate and funnel-shaped pipe); in FIG. 3 is a section AA in FIG. 2; in FIG. 4 - product interaction with an emphasis (partition) and a rotating corrugated disk; in FIG. 5 - axonometric projection of the funnel-shaped pipe with inclined stops.

 The grain chopper includes a housing 1, in which a disk is made, made in the form of a plate 2, which has perforation over its entire surface. The plate 2 is mounted rotatably on the shaft of the electric motor 3.

 Inside the plate 2, and coaxially with it, a funnel-shaped pipe 4 is placed, which with the help of the adjusting nut 5 can move in a vertical plane.

 On the inside, the funnel-shaped pipe is equipped with stops 6, which are installed at an angle to the lower (smaller) base of the plate 2. The end surfaces 7 of the funnel-shaped pipe 4, stops 6 and the smaller base of the plate 2 are corrugated.

 The housing 1 has openings 8 and 9 for the removal of solid and liquid fractions.

The grain grinder works as follows:
Pre-soaked, for example, soybean grain together with water is fed into the loading funnel and is located in the inner cavity of the funnel-shaped nozzle 4. After the chopper is turned on, the grain is distributed under the action of centrifugal forces at the inclined surfaces of the stops 6. When the plate 2 rotates, the soybean grain interacts with corrugated the surface of the base of the plate 2, as well as secondary grinding at the moment of grain contact with the corrugated end surfaces 7 of the pipe, stops 6 and plates 2.

 The crushed mass along the walls of the plate 2 rises to the discharge hole 8 and is removed outside. And the liquid fraction through the perforation enters the housing 1 and is removed through the lower hole 9.

 By increasing the area, the interaction of the grain surface with the working surfaces increases the performance of the grinder; the introduction of the design of inclined stops allows you to increase the degree of grinding of grain due to the two-phase grinding scheme, which positively affects the quality of grinding.
