Embodiment 1

[0026] Mine bin automatic control system, including industrial computer, industrial control electromechanical connection with PLC controller, PLC controller is electrically connected with interleaved control module, interleaved control module is electrically connected with several electromagnetic reversing valves, and electromagnetic reversing valve is connected with The hydraulic cylinder 3 opened and closed by the opening and closing mechanism 2 on the discharge port 11 of 1.

[0027] The opening and closing mechanism 2 is a jaw-type ore-drawing valve. The jaw-type ore-drawing valve 2 includes two sets of rotating valve plates 21. Both sets of rotating valve plates 21 are hinged with the mine bin 1. Gears 22 are connected to the rotating valve plates 21. Two sets of rotating valve plates The gear 22 on the rotating valve plate 21 meshes, and one end of one group of rotating valve plates 21 away from the gear 22 is hinged to the piston rod of the hydraulic cylinder 3 . The tw...

Embodiment 2

[0031] On the basis of Embodiment 1, the interleaved control module includes a time relay, the time relay is electrically connected to the PLC controller, the normally open contact of the time relay is electrically connected to the first switch, and the first switch is electromagnetically commutated with a part thereof The positive stroke contact of the valve is electrically connected; the normally closed contact of the time relay is electrically connected to a second switch, and the second switch is electrically connected to the positive stroke contact of another part of the electromagnetic reversing valve. The closing time and disconnection of the time relay The time is the same; the reverse travel contact of the electromagnetic reversing valve is electrically connected with the PLC controller.

[0032]When the vehicle is in place, the PLC controller is connected to the contact of the time relay. The closing time and opening time of the time relay are the same, so the first ...

Embodiment 3

[0034] On the basis of Embodiment 1 or Embodiment 2, the interleaved control module includes a time relay, the time relay is electrically connected to the PLC controller, the normally open contact of the time relay is electrically connected to the first switch, and the normally closed contact of the time relay The contacts are electrically connected to a second switch; the positive stroke contacts of several electromagnetic reversing valves are connected to a full warehouse control module, the output end of the first switch is electrically connected to a part of the full warehouse control module, and the second switch is connected to the other part of the full warehouse control module. The control module is electrically connected; the full warehouse control module is electrically connected to the PLC controller to form a feedback circuit, the reverse travel contact of the electromagnetic reversing valve is electrically connected to the PLC controller, and the closing time of the...

Abstract

The invention relates to the field of mineral conveying, and especially relates to an automatic control system for an ore storage bin. The technical scheme of the invention is that the system comprises an industrial personal computer which is connected with a PLC controller; the PLC controller is electrically connected with an interleaving control module; the interleaving control module is electrically connected with a plurality of electromagnetic reversing valves; the electromagnetic reversing valves are connected with a hydraulic cylinder which is used for controlling the on/off of opening and closing mechanisms at discharge ports of the ore storage bin. The system provided by the invention can control the alternate discharging of the discharge ports of the ore storage bin, and solves a problem that a vehicle bears an overlarge impact or rolls over from one side during the non-uniform discharge of the ore storage bin.

Description

technical field [0001] The invention relates to the field of mineral transportation, in particular to an automatic control system for mine bins. Background technique [0002] Traditional bulk material loading usually adopts belt conveying method, its main disadvantages are: first, the conveying efficiency is low, and it takes a long time for a single conveyor to fill a car. Second, it cannot solve the problem of loading viscous materials. Belt conveying is usually suitable for bulk materials without viscous materials. For materials with strong viscous materials, the roller and belt will slip, and the conveyor cannot operate normally. Third, the silo must be made into a cone bucket. Due to the single-point discharge method, the silo can only be made into a cone bucket to meet the needs. For viscous materials, the cone bucket must be hollow, and it often happens that the material cannot be discharged. . Fourth, the loading is uneven, forming a pagoda-like stacking area when ...
