Abstract

The invention discloses an automatic pulverizer for a coal sample. The machine comprises a frame, a feed hopper arranged on the frame, a pulverizing means, a sample picking means and an impurity discarding means, wherein the feed hopper is arranged at the upper part of the frame, the pulverizing means comprises a cavity in which a hammer body is arranged, the hammer body is connected with a first drive unit, the cavity is provided with a feed inlet, a discharge outlet with a screen mesh and an impurity discarding opening, the feed hopper is connected with the feed inlet, the sample picking means is connected with the discharge outlet, and the impurity discarding means is connected with the impurity discarding opening. The automatic pulverizer provided by the invention changes traditional coal dust production manners and has the following advantages: all the procedures consisting of feeding, pulverizing, screening, bottling and impurity discarding in the preparation process of the coal sample can be carried out automatically, so a high degree of automation is realized; a fast speed and high efficiency are obtained in sample preparation; sealed design is used for equipment, which is clean and green and causes no dust pollution and small noises.

Description

technical field [0001] The invention belongs to material crushing equipment, in particular to an automatic pulverizer for coal samples. Background technique [0002] At present, the coal sample pulverizer adopts a vibrating pulverizer. The coal sample is put into a round steel cup, and then the steel rod smaller than the inner diameter of the cup is put into the cover and fixed on the motor-driven On the disc, the disc rotates at a high speed, driving the steel rod in the cup to move and hit the cup wall to crush the coal sample; remove the steel cup and pour out the coal sample, sieve through a 0.2mm sieve, pour out the impurities on the sieve, and Coal powder was used as a coal sample. This method of coal sample pulverization has a large manual workload, and it takes a long time to prepare each coal sample. The working environment is noisy and dust pollution is serious. Contents of the invention [0003] In order to overcome the above-mentioned deficiencies in the prio...
