Automatic screening equipment based on coal

Abstract

The invention discloses automatic screening equipment based on coal, relates to the technical field of automatic screening, and provides the following scheme for solving the problems that when the coal is automatically screened, due to the fact that accurate screening cannot be achieved manually, the quality of the coal is prone to being mixed, the percent of pass is reduced, the manual salary ishigh, the screening time is long, the capital is wasted, and the efficiency is affected. The automatic screening equipment is characterized in that a motor is fixedly arranged at the bottom of an outer box in a sleeved mode; an output shaft of the motor is fixedly connected to a first bevel gear; the right side of the first bevel gear is provided with a vibration mechanism; the left side of the first gear is provided with a push-pull mechanism; the right side of the vibration mechanism is provided with a transmission mechanism; the vibration mechanism comprises a first fixing rod fixedly connected to the top of the outer box; and the top of the first fixing rod is fixedly connected to a first bearing. The automatic screening equipment is automatic in operation, not only accurately screensexcellent coal according to standards and improves the percent of pass, but also saves labor funds, shortens the screening time and improves the efficiency.

Description

technical field [0001] The invention relates to the technical field of automatic screening, in particular to a coal-based automatic screening equipment. Background technique [0002] Screening is the process of using a sieve to make the fine-grained materials smaller than the sieve holes pass through the sieve surface, while the coarse-grained materials larger than the sieve holes stay on the sieve surface, thereby completing the process of separating coarse and fine materials. This separation process can be regarded as It consists of two stages: material stratification and fine-grain sieving. Material stratification is the condition for separation, and fine-grain sieving is the purpose of separation. [0003] When coal is automatically screened, due to the inability to accurately screen manually, it is easy to cause the coal to be mixed up, the pass rate is reduced, and the manual wages are high, the screening time is long, waste of money, and affect the efficiency. Therefo...
