Abstract

This invention relates to agriculture. The aim of the invention is to improve the uniformity and accuracy of dosing, stabilizing the operating mode of the control system, as well as eliminating the formation and adhesion of feed on the walls of the storage bin. The feed particles under the action of the vibrating movable part 2 of the storage bin 1 fill the cells of the sector feeder 8 and drop them onto the weighing conveyor belt 12, where they are exposed to the flow equalizer 14. Next, the material flow on the tape effects its mass on the sensor 20. The resulting flow deviation generates the signal acting on the control unit 22 by an adjustable drive 23, which either accelerates or delays the flow of the material, thereby ensuring a constant flow rate at the output. 2 hp f-ly, 5 ill. i (L i i (4% oo soo 00 ND 00

Description

one

The invention relates to agriculture, in particular, to devices for the dosage of shredded root crops in feed houses and feed and food industry.

The purpose of the invention is to improve the uniformity and accuracy of dosing, stabilizing the operating mode of the control system, as well as eliminating the arching and sticking of feed on the walls of the storage bin.

FIG. 1 shows a device, a general view and a functional diagram of its control; in fig. 2 shows section A-A in FIG. one; in fig. 3 - the device, top view; in fig. 4 is a view B in FIG. 3; in fig. 5 is an electrical diagram of the layer thickness control organ.

The device for dispensing root crops contains hopper 1, having a movable part 2, equipped with sensors of the upper 3 and lower 4 levels, a vibrator 5, oscillating the movable part 2, elastic band 6, connecting along the perimeter the movable part 2 of the bunker-accumulator 1 with the fixed 7 , which includes a sector feeder 8 articulated with a variator 9, rotated by a belt drive 10 from the master roller 11 of the weighing conveyor 12, equipped with a damping device 13, a flow equalizer 14 with the element 15 reg the thickness of the flow layer, made in the form of a solenoid 16 with a working winding 17 and a bias winding 18 as well as the weighing section 19, the metering process control system consisting of a sensor 20, an adder 21, a control unit 22 for controlling an adjustable electric drive 23 and a driver 24, when In this way, the biasing winding 18 of the element 15 for controlling the thickness of the flow layer is electrically connected to the driver 24.

The device works as follows.

In order to carry out the dispensed delivery process, it is necessary to prepare the dispenser for operation. At this stage, the operator of the feed mill installs on the setting device 24 by switching the lever the desired rate of rooting of the fruits and vegetables. On the scale on the setting device 24, the required value of the installation of the latch of the variator 9 is determined, its switching

in the required position provides the necessary ratio of angular speeds of the weighing conveyor 12 and the sector feeder 8.

The operating mode of the device begins with the operator turning on the power to the dosing control system. This turns on the vibrator

- „5, oscillating movable part 2 of storage bin 1. Vibration of the movable part is carried out with the aim of eliminating the coagulation and sticking of feed particles to the walls, as well as full

-R. filling the cells of the sector feeder 8. The sector feeder 8 is the main element of the fixed part 7 of the storage bin 1, which is connected along the entire perimeter with the movable part 2 with an elastic band 6. Simultaneously with the vibrator 5, the layer thickness adjustment element 15 is set to the required distance from the tape is the weight of the measuring conveyor 12. This occurs due to the addition of magnetic fluxes generated by the solenoid windings 17 and 18.

When the power is turned on, the working winding 17 creates the main magnetic

 a stream that is designed to raise the razravnivatel51 14 material flow to a certain height from the belt weighing conveyor 12, corresponding to the minimum root layer of fruit on the belt. The bias winding 18 is electrically connected to the driver device 24, which can be configured as a potentiometer. Depending on the installed flow rate on the driver 24, a current flows through the winding 18, creating an additional magnetizing flow. The currents add up, the current of the solenoid grows, raises and holds

If the sensor 4 of the lower level shows the presence of chopped root vegetables, then the control unit 22 is turned on.

In the presence of roots electric motor 23 rotation of the leading roller 11

drives the weighing conveyor belt 12. Simultaneously with the start of operation of the conveyor 12, the sector feeder 8 starts feeding material onto the belt, since the drive of the feeder 8 is performed by a belt drive 10 from the pulley located on the drive roller 11 of the conveyor 12, the feed material you - the oscillations of the tape, which are extinguished by the damping device 13, are formed. Formed by the sector feeder 8, the hill of root crops is distributed by leveling 20

the flow teleme 14 across the entire width of the motor 15 is tera, with the leading roller of the tape.

The feed layer arriving at the weighing section 19 with its mass acts on the sensor 20. The signal arising from this is compared in the adder 21, which can be performed on a properly connected operational amplifier,. with a given. The resulting mismatch enters the control unit 22 with an adjustable drive 23, and. In accordance with the magnitude and mismatch sign, the speed of the tape and, accordingly, the sector feeder 8 either increases or decreases, the lowering of the level of shredded root crops during the operation of the dispenser triggers the sensor 4 of the lower level, which turns on the loading device.
