Problems solved by technology

[0003] Most of the existing sampling equipment is fed by manually taking coal from the coal pile, putting the coal into the conveyor belt, and directly below the end of the conveyor belt is the opening of the crushing bin of the crusher. This kind of feeding mechanism cannot control the accuracy of coal feeding, and at the same time, Unable to clean the coal accumulation on the equipment, resulting in uneven sampling and affecting the quality of sampling

Embodiment

[0024] When in use, the coal mine that needs quality inspection and sampling is put on the conveyor belt of the conveyor conveyor inlet, and the coal mine is sent to the conveyor outlet via the conveyor belt, enters the guide trough through the hopper, and then enters the crusher cabin. At this time, the shaft of the crusher is driven by the rotation of the belt pulley to drive the fixed rod on the pendulum seat fixed on the rotating plate to rotate together through the flat key. Since the fixed rod and the pendulum sleeve are movably sleeved, the pendulum sleeve is fixed The first pendulum and the second pendulum are all stretched under the action of centrifugal force, and continue to rotate in the cabin to crush the coal mine. The crushed coal mine falls from the screen to the lower hopper.

[0025] The first pendulum and two second pendulums are arranged at intervals. Since the first pendulum is arranged in the middle and the length is smaller than the length of the cabin, the ...

Abstract

The invention discloses a primary feeding mechanism. A conveying outlet is connected with an opening of a feeding hopper. An outlet in the lower portion of the feeding hopper is connected with a guidechute on the top of a crusher bin. A pendulum bob mechanism is arranged in the crusher bin. A screen is arranged at the position, below the pendulum bob mechanism, of the bin. A discharging hopper isarranged below the screen. A motor is arranged on the top of the feeding hopper. A rotating shaft of the motor is connected with the circle center of an eccentric wheel disc. One end of the eccentricwheel disc is connected with a connection rod, and the other end of the connection rod is connected with the top of a chamber interior cleaning plate. The chamber interior cleaning plate is insertedin the guide chute from the top and is movably connected with a rear plate of the guide chute. The feeding mechanism is reasonable in structure, high in sampling and crushing precision and convenientto use and maintain.

Description

Technical field [0001] The invention relates to a one-time feeding mechanism and belongs to the technical field of coal mine sampling equipment. Background technique [0002] At present, raw coal sampling refers to an important link in the quality control of the raw coal receiving process in the coking plant. The quality of coal transported to the coking plant is not uniform, so samples should be taken from different parts of the incoming coal. After the original sub-samples are mixed, crushed and reduced, they are used for analysis and inspection. The more sampling points, the more representative the sample, that is, the closer the quality of the sampled product is to the quality of the batch of raw coal. [0003] Most of the existing sampling equipment feeds coal by manually taking coal from the coal pile and putting the coal into the conveyor belt. The crushing bin opening of the crusher is directly set below the end of the conveyor belt. This feeding mechanism cannot control ...
