Description

Technical Field

[0001] The utility model relates to the field of automatic control, in particular to an automatic bin-changing system for gangue bin entry. Background Art

[0002] The gangue produced after coal washing enters the gangue bin. Usually, in order to ensure production safety, two gangue bins are usually used on the production line, one for use and one for standby. However, in the prior art, the operation of gangue bin switching requires manual switching of the mechanical flap after one of the gangue bins is full, so that the gangue enters another gangue bin. This not only requires special personnel to operate, but also has the hidden danger of overflow accidents caused by untimely observation. Utility Model Content

[0003] The purpose of the utility model is to overcome the shortcomings of the prior art and provide a gangue bin automatic changing system which has a simple structure and safe operation, and which automatically adjusts the direction of the belt conveyor by adding an over-position warning in the gangue bin to divert the gangue.

[0004] The equipment includes a gangue bin, which refers to a storage chamber for containing gangue in the prior art; there are two gangue bins in total, and the two gangue bins are arranged at intervals;

[0005] A belt conveyor is arranged on the upper part of the two gangue bins, the belt conveyor power is connected to the servo motor, and the two ends of the belt conveyor are arranged corresponding to the two gangue bins respectively;

[0006] A bin position warning unit is arranged in the gangue bin, and a signal of the bin position warning unit is connected to a servo motor.

[0007] The effect achieved in this way is that the gangue is introduced into a gangue bin through a belt conveyor. When the gangue inside it exceeds the position, the early warning unit alarms and sends a signal to the servo motor. The servo motor reverses, the belt conveyor rotates in the opposite direction, and the gangue falls into another bin.

[0008] The beneficial effects of the utility model are as follows: the utility model solves the problem that the gangue bin change in the prior art requires manual operation, realizes low-cost gangue over-position warning in the form of infrared counter-radiation, and cooperates with the servo motor to realize the forward and reverse rotation of the belt, so that the gangue can be put into the bin in both directions and the output direction can be switched after the gangue in a single bin is full. It can greatly improve production safety, reduce production risks and safety hazards caused by human factors, and has greater safety promotion value. BRIEF DESCRIPTION OF THE DRAWINGS

[0012] The realization of the purpose, functional features and advantages of the utility model will be further explained in conjunction with embodiments and with reference to the accompanying drawings. DETAILED DESCRIPTION

[0013] Reference Figure 1 The utility model discloses a waste rock storage automatic bin changing system, comprising a waste rock bin 5, wherein the waste rock bin 5 refers to a storage bin for storing waste rock in the prior art; there are two waste rock bins 5 in total, and the two waste rock bins 5 are arranged at intervals;

[0014] A belt conveyor 2 is arranged on the upper part of the two gangue bins 5, the belt conveyor 2 is connected to a servo motor 3, and the two ends of the belt conveyor 2 are respectively arranged corresponding to the two gangue bins 5;

[0015] A bin position warning unit 1 is arranged in the gangue bin 5 , and the bin position warning unit 1 is connected to the servo motor 3 by a signal.

[0016] Preferably, the signal of the warehouse warning unit 1 is connected to PLC4, and the signal of PLC4 is connected to the servo motor 3.

[0017] Furthermore, the belt conveyor 2 is centrally installed between the two gangue bins 5 .

[0018] Furthermore, the warehouse warning unit 1 is an infrared radiation warning unit, and its setting form is as follows:

[0019] An infrared signal transmitter and an infrared signal receiver are respectively arranged in the gangue bin 5, the infrared signal transmitter and the infrared signal receiver are arranged opposite to each other and connected by signals, and an anti-collision shell is provided outside the infrared signal transmitter and the infrared signal receiver.

[0020] The effect achieved in this way is that when the 5th level of the gangue bin gradually rises, the raised gangue in the middle blocks the infrared signal, thereby realizing over-level warning.

[0021] When the utility model is used, the gangue is introduced into a gangue bin 5 through the belt conveyor 2. When the gangue inside the bin exceeds the position, the early warning unit alarms and sends a signal to the PLC 4. The PLC 4 controls the servo motor 3 to reverse, the belt conveyor 2 rotates in the opposite direction, and the gangue falls into another bin.

[0022] The above shows and describes the basic principle and main features of the utility model and the advantages of the utility model. For those skilled in the art, it is obvious that the utility model is not limited to the details of the above exemplary embodiments, and can be implemented in other specific forms without departing from the spirit or basic features of the utility model. Therefore, no matter from which point of view, the embodiments should be regarded as exemplary and non-restrictive. The scope of the utility model is limited by the attached claims rather than the above description, and it is intended to include all changes within the meaning and scope of the equivalent elements of the claims. Any figure mark in the claims should not be regarded as limiting the claims.

[0023] In addition, it should be understood that although the present specification is described according to implementation modes, not every implementation mode contains only one independent technical solution.
