Description

The invention relates to metering equipment and can be used to supply various bulk materials in agricultural and forest seed processing equipment for the purpose of their separation into fractions.

Known separating device (US Pat. RF No. 2175895; B07B 1/28; publ. 11/20/2001) containing an oscillating working surface with riffles installed on it, bounded by the end and two side walls, and a feeder for feeding the initial grain mixture to the working surface. The corrugations are made in the form of plates having a height less than the height of the end or side walls and installed symmetrically at an angle to the axis parallel to the side walls.

The disadvantage of this device is the large consumption of materials, since to control the feed rate of the material it is necessary to produce new work surfaces.

A device for cleaning and calibrating forest seeds of conifers (Pat. RF No. 2170147; B07B 1/16; publ. 07/10/2001), including a loading device with a hopper and a guiding vibratory tray, orienting and sorting device of several pairs of cylindrical multi-stage shafts installed with the possibility of rotation in opposite directions and with a gap relative to each other, increasing from the loading device to the discharge end, receivers of impurities and seeds.

The disadvantage of this device is that the feed rate of bulk material depends on the configuration of the feed hopper.

Closest to the proposed device is a separator of bulk materials (US Pat. RF No. 2200636; B07B 1/04; publ. March 20, 2003), including a hopper mounted at an angle to the horizontal surface, and the shutter. The hopper is a channel with screening devices installed in it motionless at an angle to the horizontal plane and assembled from combs with cantilevered fingers. Above the combs, at an acute angle to them, the shutters are mounted on the hinges in such a way that one edge of the shutter with the hinge is located above the layer of the material being processed, and the other edge of the shutter is pressed against the combs with the help of a load or spring, directed along the direction of movement of the material layer and has the ability move away from the combs under the influence of the flow of material. Adopted for the prototype.

The disadvantage of this device is that the angle of inclination of the damper is determined by a spring or a load. The pressure on the dampers depends on the volume of bulk material coming from the hopper: the larger the volume, the greater the pressure, and the more the dampers open; with decreasing volume, the degree of opening of the dampers decreases. All this complicates the adjustment of the feed rate of bulk material.

The main objective of the invention is the creation of a new device that allows for a dosed uniform supply of bulk material to the working bodies of the machine (rollers).

The technical result is achieved by the fact that in the device for feeding seeds, including a hopper mounted under the fragile surface to a horizontal surface, the shutter, according to the invention, the hopper is made triangular, with the ability to adjust the angle of inclination; the flaps are attached to the housing of the hopper with the possibility of adjusting their angle of inclination relative to the longitudinal axis of the hopper, which improves the uniformity of seed supply to the rotating rollers.

In FIG. 1 shows a diagram of a device for feeding seeds.

A device for feeding seeds contains a triangular hopper 1, triangular shutters 2 and rotating rollers 3 mounted on the housing 4.

The operation of the device for feeding seeds is as follows.

The triangular hopper 1 is set to the required angle. The triangular shutters 2 are set at the required angle and are rigidly fixed. Material (seeds) is poured into the hopper 1, which, under the force of gravity and vibration from the rotating rollers, begins to pour down and rests against the shutters 2. By adjusting the angle of inclination of the hopper 1 and shutters 2, the necessary feed rate of bulk material can be achieved. The material is fed to the rollers 3, where it is divided into fractions.

The inventive device for feeding seeds, in comparison with the prototype, due to the presence of three rigidly fixed triangular dampers allows to increase the uniformity of supply of material, and by changing the angles of inclination of the triangular hopper and triangular dampers, to regulate the speed and volume of the supplied bulk material on the rotating rollers.
