Embodiment approach 1

[0033] The application of a reciprocating coal feeder driven by a linear motor in the present invention is applied to a large vertical coal bunker. The feed port of the overall device is installed in parallel between the discharge port below the coal bunker and the belt conveyor, replacing the original one. reciprocating coal feeder.

[0034] It consists of three parts: the discharge device, the drive device and the bracket (refer to the attached figure 1 And attached figure 2), the bracket 11 is welded into a cuboid with front and rear openings with thick steel plates, and the steel plate at the upper middle position of the bracket 11 is cut and removed, and its width matches the width of the discharge chute 6. At the upper steel plate on the left side of the bracket 11 Install the upper left guide rail 7 and the upper right guide rail 8 at the upper right steel plate, install the lower left guide rail 9 at the lower steel plate on the left side of the bracket 11, and insta...

Embodiment approach 2

[0041] The application of a reciprocating coal feeder driven by a linear motor in the present invention is used to regulate the coal flow in a large vertical coal bunker. The feed port of the overall device faces upwards and is installed in parallel between the discharge port below the coal bunker and the belt conveyor. , to replace the original reciprocating coal feeder. At the same time, the three-phase AC power supply supplies power to the coils of the primary 2 of the left linear motor and the primary 3 of the right linear motor through the three-phase AC frequency regulator, changing the frequency of the three-phase AC power, thereby changing the moving speed of the discharge slider 1, and achieving the adjustment of fuel consumption. Purpose of coal flow. Others are the same as Embodiment 1.

Abstract

The invention belongs to the technical field of mining equipment, and relates to a reciprocating type coal feeder driven by a linear motor. The reciprocating type coal feeder is an electromechanical device applied to a discharging port in the bottom of a large coal bunker and used for controlling the discharging state of the coal bunker. The reciprocating type coal feeder is characterized in that a middle transmission mechanical part is not arranged, compared with an existing reciprocating type coal feeder, the reciprocating type coal feeder driven by the linear motor is the electromechanical device having the advantages of being small in size, light in weight, low in failure rate and manufacturing cost and the like, and the reciprocating type coal feeder driven by the linear motor is an ideal upgrading product for the existing reciprocating type coal feeder.

Description

technical field [0001] The invention relates to a reciprocating coal feeder driven by a linear motor, which belongs to the technical field of mining equipment, and is an electromechanical device applied to a discharge port at the bottom of a large coal bunker in a coal mine to control the discharge state of the coal bunker. Compared with the existing reciprocating coal feeder, the present invention has the advantages of small size, light weight, low failure rate, low cost, etc., and is an updated product of the existing reciprocating coal feeder. Background technique [0002] The coal feeder is an indispensable and important equipment for the production of coal mines, coal washing plants and power plants. It is usually installed at the bottom of the cylindrical coal bunker, and mainly completes the coal blending and feeding between the coal bunker and the belt conveyor in the entire production process . According to production needs, the coal in the coal bunker is continuou...
