Background

In traditional grain warehouse-out technology, every feed bin bottom sets up a hand, electric gate, and the flow of warehouse-out material needs the artifical aperture size of constantly adjusting hand, electric gate, until satisfying the design output of later production line.

Wherein, the hand gate and the electric gate are provided with an upper set of gate plate and a lower set of gate plate which respectively control the opening, the closing and the opening of the gate. One set is by the motor control upper portion electric gate open or close (full-open or full-closed), and one set is by the hand wheel to control the manual gate opening size in lower part to the flow of control delivery material. When the grains need to be taken out of the bin, motors in the hand gate and the electric gate can be started remotely through a computer in the central control room, so that the electric gate is opened completely, but the discharge flow needs to be adjusted manually under the bin according to the flow value displayed by the metering scale. If the opening of the manual gate is small, the yield of grains discharged from the bin and entering a subsequent production line is small, so that the waste of productivity and power consumption is caused, and the production benefit is low; if the manual gate is opened greatly, the flow rate exceeds the design yield of the production line, so that the material blockage of the elevator and the subsequent equipment is caused, and the production line is stopped. Therefore, the traditional grain discharging process needs to adjust the opening of the gate continuously by manpower after the material bin starts discharging until the design yield of the subsequent production line is met.

Detailed Description

The following describes embodiments of the present invention with reference to the drawings.

As shown in fig. 1-4, the intelligent control system for the discharge rate of the bin of the present embodiment includes a bin 10, an electric gate 20, a bucket elevator 30 and a weighing scale 40, the electric gate 20 is installed at a discharge outlet at the bottom of the bin 10, an outlet of the electric gate 20 is communicated with a feed inlet of the bucket elevator 30 through a first chute 50, a discharge outlet of the bucket elevator 30 is communicated with a measuring cylinder in the weighing scale 40 through a second chute 60, the electric gate 20 includes a motor 21, a horizontal movement mechanism, an electronic ruler 22 and a shutter 23, the motor 21 drives the shutter 23 to move horizontally through the horizontal movement mechanism to open or close the discharge outlet of the bin 10, a sliding end of the electronic ruler 22 is connected with the shutter 23, and a sliding direction of the sliding end of the electronic ruler 22 is parallel to a moving direction of the horizontal movement mechanism.

The horizontal moving mechanism comprises a screw rod 24 and a nut 25 matched with the screw rod, the motor 21 drives the screw rod 24 to rotate, the lower surface of the gate plate 23 is vertically fixed with a vertical plate 28, and the nut 25 is fixed on the vertical plate 28.

The electric gate 20 comprises a shell 26, the shell 26 is a frame plate type formed by surrounding plates, a vertical partition plate 27 is arranged inside the shell 26, one side of the partition plate 27 and the shell 26 are surrounded to form a material channel, the upper end of the material channel is communicated with a bottom discharge hole of the storage bin 10, the lower end of the material channel is communicated with a chute 50, an insertion slot for inserting the gate plate 23 is formed in the partition plate 27, the gate plate 23 moves to control the opening or closing of the material channel, the vertical plate 28 is arranged on the other side of the partition plate 27, and the motor 21 is arranged outside the shell 26.

A strip plate 29 is fixed at the lower end of the vertical plate 28, one end of the strip plate 29 is welded at the lower end of the vertical plate 28, the other end of the strip plate 29 extends out of a strip seam 261 formed in a surrounding plate of the shell 26, the electronic ruler 22 is installed on the outer surface of the shell 26, the sliding end of the electronic ruler 22 is vertically connected with the other end of the strip plate 29, and when the sliding end of the electronic ruler 22 slides, the strip plate 29 moves along the length direction of the strip seam 261.

When the electric gate 20 is opened, the motor 21 rotates positively to drive the screw rod 24 to operate, and then the gate plate 23 is driven to move rightwards through the nut 25, and at the moment, the larger the electric gate 20 is opened; on the contrary, when the electric gate 20 is closed, the motor 21 rotates reversely to drive the screw rod 24 to rotate reversely, and then the nut 25 drives the gate plate 23 to move leftwards, and at this time, the closer the electric gate 20 is, the smaller the electric gate is. The displacement of the shutter 23 synchronously displaces the electronic ruler 22.

The electronic ruler 22 is also called a displacement sensor, and converts mechanical displacement into linear resistance output through a potentiometer element, the variation of the resistance value reflects the magnitude of the displacement, namely the opening degree of the electric gate 20, and the potentiometer is connected with a power supply to convert the resistance variation into voltage output, so that the electric signal can be directly sent to a PLC system for data processing. And meanwhile, the flow value of the metering scale 40 is collected through 485 communication and is sent to the PLC system. The PLC compares the data with the set flow through software calculation, if the data is smaller than the set flow, the PLC sends an instruction to enable the motor 21 of the electric gate 20 to rotate forward to drive the gate plate 23 to open a small distance (which can be set according to actual conditions), then collects and compares new flow values again, sends and executes a new instruction, and repeats the steps until the flow is consistent with the set flow; otherwise, the PLC sends a command to make the motor 21 rotate reversely to drive the gate plate 23 to be opened slightly.
