The invention discloses a self-open type block coal conveying spiral chute. The self-open type block coal conveying spiral chute is mainly composed of a support I, a support II, a connecting rod I, a connecting rod II, a fixed plate, an inclined plate and a movable plate, wherein the fixed plate is a rectangular plate provided with an arc, the fixed plate is fixedly arranged on a bin wall, the lower end of the fixed plate is connected with the inclined plate, the inclined plate is a rectangular plate, an angle is kept between the inclined plate and the fixed plate, the support I and the support II are respectively arranged on the bin walls of the two ends of the upper part of the fixed plate, round holes are formed in the support I and the support II respectively, the support I is connected with one end of the connecting rod I by virtue of a pin shaft in the round holes, the support II is connected with one end of the connecting rod II by virtue of the pin shaft in the round holes, the connecting rod I is made from channel steel, a round hole is formed in one end of the connecting rod I, the connecting rod II is also made from the channel steel, and a round hole is also formed in one end of the connecting rod II. The self-open type block coal conveying spiral chute solves the problem which can not be solved by an L-shaped structural spiral chute, namely block coal falls off on the half way, and avoids the problem that follow-up normal production is influenced as the block coal is accumulated in a chute slideway.
Description
technical field [0001] The invention relates to a mechanical device, in particular to a mechanical device for preventing lump coal from falling into a cylindrical coal storage bunker in coal mines and coal preparation plants. Background technique [0002] Anti-breakage of lump coal is one of the effective measures for coal classification and utilization. After coal is classified into lump coal and fine coal according to particle size, lump coal can be used in coal chemical industry or civil fuel. Its price is much higher than that of fine coal, thus reducing The crushing rate of lump coal has become an effective method for coal mining enterprises to improve economic benefits. How to maximize the output of lump coal, reduce the breakage rate of lump coal during storage, and reduce the breakage rate of lump coal is a major problem that the coal industry needs to solve urgently. Due to the complex environment in the coal bunker, repeated changes in the coal level will inevitab...
