Abstract

The invention discloses a hopper pad for a coal separator. The hopper pad for the coal separator comprises a square pad body, an isolating rib is arranged above the pad body, an isolating groove is arranged at each of two sides of the isolating rib, a first elastic rib array composed of first elastic ribs is arranged in each isolating groove, and a second elastic rib array composed of second elastic ribs is arranged at the back of the pad body. The hopper pad for the coal separator uses the pad body made of hard rubber in an integral molding mode; because both the upside and downside of the pad body are provided with elastic rib arrays, a hopper bottom plate can be protected, and on the other hand, the hopper vibrating effect is reinforced, and the coal dressing efficiency is improved. The hopper pad is simple in structure, low in cost and convenient to use.

Description

technical field [0001] The present invention relates to coal mining equipment, more specifically a hopper pad for a coal separator. Background technique [0002] A coal separator is a machine used to separate raw coal impurities and is a very common coal mining and processing equipment. Since the hopper of the coal separator adopts vibration coal separation, the bottom of the hopper is very worn and needs to be replaced regularly, which costs a lot. Contents of the invention [0003] The invention mainly solves the technical problems existing in the prior art, thereby providing a hopper pad for a coal separator. [0004] Above-mentioned technical problem of the present invention is mainly solved by following technical scheme: [0005] A hopper pad for a coal preparation machine, the hopper pad for a coal preparation machine includes a square pad main body, an isolation rib is provided above the pad main body, and the two sides of the isolation rib are respectively An is...
