Description

The utility model relates to the machine-building industry, and specifically to devices for loading bulk material into silos and can be used in various sectors of the agro-industrial complex, both in open and closed silos.

A device for loading bulk materials into a hopper for storing them is known, comprising a loading funnel for feeding bulk material into a hopper and located under a loading funnel and coaxially with a bulk material distributor made in the form of a hollow truncated cone enriched with its narrow part, having a central inlet for bulk material, in the direction of the feed funnel, the diameter of the outlet of which, located on its narrowed part, facing down, is larger than the diameter of the narrowed part Itel material (Patent US 3868028 A, 02.25.1975).

The known device does not sufficiently ensure the distribution of bulk material in the hopper when it is loaded. The degree of uniformity of this distribution is not too high, since the material supplied to the hopper is not sufficiently divided into streams. Basically, the material enters the central inlet of the distributor and the movement of material along the surface of the wall of the distributor, which is insufficient for uniform loading throughout the hopper. A device for loading bulk materials into a hopper for storing them is known, comprising a loading funnel for feeding bulk material into a hopper and located under a loading funnel and coaxially with a bulk material distributor made in the form of a hollow truncated cone facing its narrow part, having a central inlet for bulk material, towards the loading funnel, the diameter of the outlet of which, located on its narrowed part, facing down, is larger than the diameter of the central inlet The hole of the truncated cone of the material distributor. The hollow truncated cone of the distributor is made with holes in its wall located staggered along the surface of the said wall with the formation of rows of holes located along the height, and the distributor is equipped with truncated cones located one above the other, installed to adjust the area of the holes in the wall of the distributor by turning them [RF patent No. 2225821, IPC B65D 88/54, B65G 65/40, “Device for loading bulk materials into a hopper”, authors: Tretyakov G.M. et al., publ. March 20, 2004., BI No. 14].

The disadvantage of this technical solution is the complexity of the design and the complexity of its implementation. When loading bulk material, the rectangular openings of the distributor become clogged, the material sticks to the walls of the cones, which makes them impossible to rotate, causing damage to the device.

The technical result of the proposed device is to simplify the design and increase its reliability.

The technical result is achieved by the fact that in the device for loading bulk materials into the hopper for storing them, containing a loading funnel for supplying bulk material and located under the loading funnel on the shaft, a distributor of bulk material coaxial to it, the distributor is made of at least four blades with the possibility of constant and uniform rotation around the axis of the shaft, the blades are made helical with an angle of attack of 18-21 °, each blade is a half-blade shape, the top of which is fixed to the shaft aspredelitelya.

The execution of the distributor of at least four helical blades with an angle of attack from 18 ° to 21 °, provides a constant and uniform rotation around their own axis, and therefore a uniform distribution of material over the cross section of the loaded hopper.

Figure 1 shows a device for loading bulk materials into the hopper.

Figure 2 shows a view along section aa.

Figure 3 shows a view along section BB.

Figure 4 shows the location of the angle of attack of the blade of the distributor of bulk material.

Figure 5 shows a graph of the influence of the angle of attack of the blade on the diameter of the dispersion of the material.

A device for loading bulk materials into the hopper consists of a loading funnel 1, a shaft 2, at least four screw-shaped blades 3, a hopper 4, an outlet 5.

This device is installed on a container for loading bulk material and works as follows. Bulk material, flowing out of the loading mechanisms, enters the loading funnel 1, from there from its outlet 5 goes to the blades 3, mounted on the shaft 2 with the possibility of rotation around its axis and causes them to rotate in a circular motion under the action of gravitational forces arising from the flow of granular material. Thus, the material is evenly distributed over the entire cross section of the hopper 4.

The proposed device for loading bulk materials into the hopper has a simple and reliable design, ease of manufacture, versatility, lack of energy consumption, and ensures uniform distribution of bulk material over the entire cross section of the loaded container.
