RU52342U1 - GRAIN MINUSPUSTER - Google Patents

Abstract

The invention relates to the feed industry and agriculture. Mini-flattening machine refers to a device for flattening grain in order to increase its nutritional properties. The design used a device for internal conditioning, a drive from an electric motor through a V-belt drive directly to the shell, and the passage through the rollers of solid inclusions was carried out by turning the platform with the conditioning roller shaft mounted on it. The platform is spring-loaded and it is possible to change the stiffness of the springs to adjust the thickness of the flattening grain.

Description

Mini-flattening machine refers to devices for flattening grain in order to increase its nutritional properties and can be used in agriculture for the preparation of animal feed in a private farm or in the farm.

Known roller grain conditioner (certificate for utility model No. 31517, 7 V 02 C 4/06) containing a hopper with a slide gate, a pair of rollers rotating towards each other, with axes located in a horizontal plane, one of which is fixed, and the other with the ability to move in the plane of the axes; a safety spring and an adjusting-and-clamping mechanism of the axis of the movable drum, while a cup with a pressing spring and a rod with an adjusting screw and nut are located in the safety spring.

The disadvantages of the conditioner are: large dimensions and weight, high energy costs for the drive.

The closest in technical essence is a thermomechanical conditioner for grain (see, for example, patent No. 2121398 С1 6 В 02 С 4/42, В 02 С 9/00) including a frame, a drive, a conditioner for internal conditioning, in the form of a shell with a heating an element installed inside the shell of the cantilever roller, the bearing housing of which is mounted by means of a spring on the frame, and to regulate the gap between the working surface of the roller and the inner surface of the shell, a wedge is moved by a screw pair along the guides made roller bearing housing, and the guide formed in the protrusion is rigidly fixed to the shaft. The roller shaft through a V-belt drive and a power take-off shaft is kinematically connected to another

V-belt drive of the drive of rotation of the shell through the axis and V-belt pulley.

The disadvantages of this design are:

1. The complexity of the design in the presence of two V-belt drives.

2. Large dimensions and weight.

3. When the wedge mechanism is located to the left of the axis of rotation of the shell and the roller, the passage of solid inclusions between them is impossible, because the wedge will not allow the roller to move away from the surface of the shell.

4. The proposed dimensions of the spring and its stiffness do not allow solid objects to pass more than 6 mm thick and lead to breakdown of the conditioner.

5. The use of electric heating of the shell complicates the design and increases the energy consumption without tangible benefits and improve the quality of conditioning.

The objective of our invention is to create a small-sized, simple in arrangement and operation, with minimal material costs, safe to use, high-performance grain conditioner with the possibility of using it in a private peasant farmstead, using a household electrical network.

An example of a mini-flattening grain is shown in the figures. Figure 1 is a schematic diagram of a mini-flattening grain, the main view is a vertical projection; figure 2 is the same in plan: figure 3 is a computer photograph of a prototype.

The minisplitter for grain consists of a frame 1 (Fig. 1), an electric motor 2, a V-belt drive 3 for transmitting rotation to the shell 13 (Fig. 2) by means of the wedge groove 12 located on its outer surface. The shell rotates in the bearing assembly 11. Inside the shell 13 cantilever

a roller 10 is installed, which rotates on the shaft in bearings, and the other end of the shaft is mounted on a platform 9, which is pivotally mounted on the frame 3 with one end, and rests on the spring 7 with the other end, the rigidity of which can be changed with the adjusting nut 6 (Fig. 1).

For feeding grain there is a hopper 4 with a slide gate 5, equipped with a grain distribution device in the form of a gutter. A scraper 8 cleans the rolled grain from the inner surface of the shell 13 and the outer surface of the drum 10 and sends it to a container for collection or storage.

Minisplitter works as follows. The grain is poured into the receiving hopper 4. The motor 2 is turned on. A torque through the V-belt drive 3 drives the ring 13. The slide gate 5 is opened, feeding the grain to the ring and the roller 10 and the necessary conditioning thickness is set, decreasing or increasing the spring stiffness 7 with a nut 6. Grain plates after conditioning with a scraper 8 are issued from the conditioner. When a solid inclusion falls into the gap between the inner surface of the shell and the outer surface of the roller, the roller together with the platform 9 rises up, overcoming the resistance of the spring 7, passes the solid inclusion and returns to its original position.

The mini-pliers of the proposed design are manufactured, tested and have shown high performance and flattening quality. The performance of the mini-pliers is 250 kg / h with a total weight of about 30 kg. Electric motor power 0.55 kW. (Figure 3).

Claims (1)
