Abstract

The utility model discloses a coal screening machine which comprises a rack, a hopper, a screen and a drive motor, wherein the hopper is arranged on the top of the rack, the screen is arranged inside the rack, and the drive motor is arranged on one side of the rack. The screen is provided with a push rod, a cam connected with the push rod in a matching mode is arranged at the output end of the drive motor, a conveyor belt which is located below the screen is arranged inside the rack, and a screw feed mechanism is arranged between the screen and the hopper. By means of the screw feed mechanism, coals in the hopper can fall into the screen slowly, and the screen is prevented from being damaged by overlarge impact force. The coal screening machine is simple in structure and suitable for popularization and application.

Description

A kind of coal ore screening machine

Technical field

The utility model relates to a kind of coal ore screening machine.

Background technology

At present, employed coal ore screening machine in the operation of colliery, its enter material way is generally dead-beat, namely need the grate coal ore directly to be dropped on the screen cloth by hopper, because the quality of coal ore is bigger, above discharged way damages or internal injury screen cloth probably, influences the service life of screening machine.

Summary of the invention

The technical problems to be solved in the utility model provides a kind of slowly pan feeding, and is easy to use, the coal ore screening machine of long service life.

For addressing the above problem, the utility model adopts following technical scheme:

A kind of coal ore screening machine, comprise frame, and be arranged on the hopper of frame top, and be arranged on the screen cloth of frame inside, and be arranged on the drive motors of frame one side, described screen cloth is provided with push rod, described drive motors output is provided with the cam that is connected with push rod, also be provided with conveyer belt in the described frame, described conveyer belt is positioned at the screen cloth below, is provided with screw feed mechanism between described screen cloth and the hopper.

As optimized technical scheme, described drive motors is stepper motor.

As optimized technical scheme, described hopper is taper.

The beneficial effect of the utility model coal ore screening machine is: by set screw feed mechanism, make the material in the hopper to drop into slowly on the screen cloth, the injury of avoiding excessive impulsive force that screen cloth is caused, and the utility model structure is comparatively simple, is fit to promote the use of.

Description of drawings

In order to be easy to explanation, the utility model is done to describe in detail by following specific embodiment and accompanying drawing.
