[0002] As an important structure in mining production, the chute is an important transportation channel for ore to flow down. The control method of ore discharge is often different according to the different mining processes. In the past, vibration ore discharge and hydraulic ore discharge were mainly used. The ore discharged by this type of equipment is very easy to leak out of the mine car, which brings certain inconveniences to mining production. In addition, this type of equipment often requires specialized production, which is not convenient for mines to invest in production by themselves, and the production cost is high. There is also a method in the prior art that uses the traction of a wire rope to control the lifting and lowering of the lower end of the chute, so as to achieve control of the ore discharge amount. However, the wire rope used in this method has poor stability and is easy to shake, and connecting the wire rope to the chute is likely to hinder the transportation process of the ore.

[0003] In view of this, it is necessary to design a chute ore placing device to solve the above problems. Utility Model Content

The iron remover 5 includes a fixed frame connected to the base plate 1, a magnet 52 in the cavity of the fixed frame, a conveyor belt 53 surrounding the outer periphery of the fixed frame, and a driving motor 54 for driving the conveyor belt 53 to move. The width of the fixing frame (from the side panel 1 212 to the side panel 2 213) is greater than the width of the movable tongue (from the side panel 1 212 to the side panel 2 213) and is equal to the width of the magnet 52 (from the side panel 1 212 to the side panel 2 213); the magnet 52 is located directly above the movable tongue.

The iron remover 5 comprises a fixed frame connected to the substrate 1, a magnet 52 in the cavity of the fixed frame, a conveyor belt 53 surrounding the outer periphery of the fixed frame, a driving motor 54 for driving the conveyor belt 53 to move, a driving roller 51 connected to the driving motor 54, a control switch 1 55 arranged on the substrate 1, and a magnetic field perturbation instrument arranged at one end away from the electric push rod; the driving roller 51 drives the conveyor belt 53 to move; that is, the fixed frame is divided into a magnetic field area (arranged with the magnet 52) ​​and a demagnetization area (arranged with the magnetic field perturbation instrument); the driving motor 54 is located at a side away from the traction device and close to the magnet 52. The width of the fixed frame (the direction from the side plate 1 212 to the side plate 2 213) is greater than the width of the movable tongue (the distance from the side plate 1 212 to the side plate 2 213) and is equal to the width of the magnet 52 (the direction from the side plate 1 212 to the side plate 2 213); the magnet 52 is located directly above the movable tongue.

The telescopic shaft 412 and the fixed plate 413 in the electric push rod are respectively provided with a gap between the movable tongue.

[0032] The following is a description of the working process of a chute ore discharge device provided by the utility model:

[0033] like Figures 1-2 As shown, when the control switch 1 55 for controlling the iron remover 5 and the control switch 2 43 for controlling the traction device on the substrate 1 are turned on at the same time, the control motor 411 extends the length of the telescopic shaft 412 forward, thereby driving the fixed plate 413 to rotate, so that the outlet of the second cavity is lowered; when the control motor 411 shrinks the length of the telescopic shaft 412 backward, it drives the fixed plate 413 to rotate back, so that the outlet of the second cavity is recovered. At the same time, the drive motor 54 drives the conveyor belt 53 to move (movement direction: from close to the electric push rod to away from the electric push rod). During operation, when the mineral flows from the opening of the substrate 1 to the movable tongue, the magnet 52 in the iron remover 5 located just above the movable tongue will absorb the iron-containing minerals in the mineral, and be transported from the end close to the electric push rod to the end away from the electric push rod along the conveyor belt 53. When it is transported to the demagnetizing field area (i.e., the end away from the electric push rod), the iron-containing minerals fall down and are collected, and the first iron removal operation is performed on the mineral, so that the iron in the mineral is separated in time to avoid damage to subsequent process equipment. The remaining minerals enter the second cavity along the first cavity, and the motor 411 is controlled to extend the length of the telescopic shaft 412 forward, thereby driving the fixed plate 413 to rotate, so that the outlet of the second cavity is lowered and the minerals are transported to the destination; and when the minerals in the movable tongue splash out, the enclosure 3 located below can collect the minerals without causing waste; when the mineral transportation volume reaches the standard, the motor 411 is controlled to shrink the length of the telescopic shaft 412 backward, thereby driving the fixed plate 413 to rotate back, so that the outlet of the second cavity is recovered and no more minerals are transported, thereby realizing the control of the ore release volume.

[0034] In summary, the utility model provides a device for releasing ore from a chute. The device is provided with a movable tongue connected to a base plate and rotatable, a fence connected to the base plate and placed under the movable tongue, a traction device for pulling the movable tongue to move, and an iron remover placed above the movable tongue; when the traction device is turned on, the opening of the movable tongue can be driven to rotate, thereby realizing the control of the amount of ore released; and when the minerals in the movable tongue splash out, the fence located below can collect the minerals without causing waste; at the same time, the iron remover located above the movable tongue performs the first iron removal operation on the minerals, and separates the ironware in the minerals in time to avoid damage to subsequent process equipment; and realizes the control of the amount of ore released in a refined manner. By adopting a traction device composed of a motor connected to a base plate, a telescopic shaft connected to the motor, a fixed plate connected to the telescopic shaft, and a crossbar connecting the electric push rod to the second cavity, it is more stable when working with the movable tongue, so the control of the amount of ore released by the movable tongue can be more accurately controlled.

Although the utility model is described in detail with reference to the preferred embodiments, those skilled in the art should understand that the technical solution of the utility model can be modified or replaced by equivalents without departing from the spirit and scope of the technical solution of the utility model.
