Abstract

The invention relates to dosing devices and can be used for dosing bulk and poorly flowing feed from bins. The purpose of the invention is to improve the dosing accuracy by maintaining a constant speed of movement of the feed particles. The increase in the accuracy of dosing and the reduction of the energy consumption of the dosing process occurs due to the conical bottom 2 with some curvilinear generatrix having a convex working surface. Under the action of vibration transmitted by the vibration exciter of torsional vibrations 9 to the carrier plate 7, and consequently to the conical bottom 2 with the stimulating cone 5, the feed enters from the hopper I through the annular channel to the conical bottom 2 and is discharged to the outside through the outlet 3. The speed of movement of the feed particles throughout the length of the curvilinear generatrix of the conical bottom 2 is constant in magnitude due to the fact that in the upper part of the angle of inclination the generatrix is minimal at the maximum amplitude of oscillations, and in the lower part the generatrix has an angle Maximum Feed value at the minimum vibration amplitude. This makes it possible to eliminate the loading of feed in the area of its descent from the conical bottom 2 and, consequently, to improve the metering accuracy. I 3. n. F-ly, 2 ill. (L

The invention relates to dosing devices that can be used in agriculture for dosing bulk and poorly flowing fodder.

The purpose of the invention is to improve the dosing accuracy by maintaining a constant speed of movement of the feed particles.

FIG. 1 shows schematically a bunker vibrating feeder for feed; at (f) iii. 2 section A-A in FIG. one.

The bunker vibrating dozer contains a bunker 1, in the lower part of which there is a conical bottom 2 with a curvilinear generatrix, and a convex working surface in the direction of the motive cone with an outlet nozzle 3. On the conical bottom 2 with the help of racks 4, there is a fixed cone 5 with blades 6, hym. megrichno fixed on its outer surface. To the conical bottom 2, a nonsuch plate 7 is rigidly attached, which by means of elastic hangers 8 is attached to the base of the bunker I. At the end of the carrier plate 7, vibration exciter 9 is torsionally vibrating. In this case, the angle of inclination of the forming bottom is equal to 5–25 ° in the initial section and 50–70 ° in the section of the outlet nozzle.

As can be seen from the equation, OS, and L are interconnected by a one-to-one dependency, and therefore, it is possible for any food to construct a conical bottom forming with an inclination angle continuously increasing in the Q direction of the outlet nozzle.

The use in a bunker vibrator for feeds of a conical bottom with a convex working surface in the direction of the stimulating cone (at a constant speed of movement of feed particles) allows to reduce the thickness of the layer in the zone of the outlet nozzle and thereby eliminate the loading of the feed. Due to the small thickness of the layer, the particles of its upper part are connected with the surface of the conical bottom due to the forces of friction and adhesion and converge with the bottom speed, 1; the speed of the particles of the lower layer. In addition, when the feed moves along the convex bottom of the bottom, segregation of particles is prevented, since the torsional vibrations of the bottom ensure a continuous movement of the feed particles and the time of vibrating processing is very short. As a result, the accuracy of the dosing of feed is higher.
