Abstract

The aim is the automatic, uniform storage of bulk materials in a circular tank. The stated purpose is achieved by transporting the material into the hopper of the storage screw with a longitudinal discharge on the lower part of the screw trough, equipped with a drive unit, mobilely placed on the upper surface of the peripheral wall of the circular tank. The circular movement of the storage screw is controlled automatically by means of a capacitive switch after the material has been stored to the sensing electrodes located on the lower part of the screw trough by the drive unit.

Description

(54) Rotary equipment for automatic storage of bulk materials

The aim is an automatic even loading of bulk materials into a circular tank. This is accomplished by conveying the material into a hopper with a longitudinal hopper on the bottom of the screw trough provided with a drive unit disposed mobilely on the top surface of the peripheral wall of the circular tank. to the sensing electrodes located at the bottom of the auger trough of the drive unit.

GIANT. 1

The invention relates to a rotary device for automatically loading bulk materials into a circular tank.

When preparing the flavored straw, it is usually stored in a layer 1 m high by means of a conveyor belt with a folding trolley. However, the operation of the conveyor as well as the treatment of the straw layer requires a considerable amount of manual work.

The aforementioned drawbacks are eliminated by the method of storing straw into a circular tank by means of a rotary device according to the invention, which consists in that the trough of a storage screw with unidirectional 360 ° circular displacement, whose vertical axis of circular displacement is perpendicular shaft in the center parts are provided with a longitudinal hopper. The storage screw is provided with a drive unit, which is mobile on the upper surface of the circumferential graft of the circular tank and on the lower part of the drive unit with sensing electrodes of the capacitive switch. The output of the electronic part of the capacitive switch is connected to the first input of the bistable flip-flop, the output of which is connected both to the contour of the circular screw shift and secondly to the input of the timer, whose output is connected to the second input of the bistable flip-flop.

When the bulk materials are loaded into the circular tank by means of the rotary device according to the invention, the material is automatically evenly loaded into the circular tank, even if the material feed to the rotary device is irregular.

1 is a mechanical part and FIG. 2 is an electronic part of the rotary device. FIG.

In the middle of the annular tank 2 there is a perpendicular shaft 2 which forms the vertical axis of the circular displacement of the storage auger. The storage auger 4 is provided with a circular hopper 3, a longitudinal hopper 5, a drive unit 11 disposed mobilely on the upper surface of the peripheral wall of the circular tank 11, and capacitive switch sensing electrodes 7 located at the lower part of the screw channel. The low voltage terminal 9 is connected via the start 10 and the shut-off button 11 both to the worm drive contactor 12 and to the electronic input of the capacitive switch 13, the output of which is connected to the first input of the bistable flip-flop. 15 of a circular auger shift and, secondly, an input of a timer 16, the output of which is connected to a second input of a bistable flip-flop 14.

When the bulk material is loaded into the circular tank 2 according to the invention, the material is dosed into the circular hopper 2 of the storage auger 4, from which the longitudinal discharge hopper 5 gradually flows into the circular tank 2 as soon as the material J3 approaches the sensing electrodes 7 near the peripheral wall. For example, a pulse is applied to the first input of the bistable flip-flop 21 ' which flips, resulting in the application of a voltage to the contactor 21 ' which actuates the rotary screw drive drive unit 6 and the timer 16.

After the set time interval has elapsed, the output of the timer 16 connects the pulse to the second input of the bistable flip-flop 21 »which flips, thereby disconnecting the voltage from the timer 16 and the contactor 21», causing the drive unit 5 of the storage auger 1 stops. Upon displacement of the storage auger 4 by the desired angle, the magnitude of which is determined by the time interval of the timer 21 ', the material is released from the longitudinal hopper 5 and the material storage proceeds in the next section.

The rotary automatic bulk storage device of the invention can be used, for example, in the preparation of fermented straw for cattle feeding or in the preparation of compost from liquid excrements of farm animals and straw or other suction materials.
