Technical Field

The invention relates to the field of crushers, in particular to a vertical shaft hammer crusher with a main shaft protection function.

Background

With the modernization of the coal industry, the coal mining process has undergone a great change, and the top coal caving process has been scientifically applied and developed. When the hardness of the coal is f2, the strength of the coal is not easy to be damaged, the top coal is easy to form blocks, when a working face encounters a fault, the number of the blocks is increased, the blocks and the blocks are not easy to pass through a transfer conveyor or a transfer point, damage in the forms of collision, smashing and the like is generated to transportation equipment, and difficulty is brought to underground safe transportation. The crusher fully crushes the blocky coal and the blocky rocks to ensure that the blocky coal and the blocky rocks smoothly pass through the transfer conveyor or the transfer point, thereby ensuring the underground safe transportation and production. At present, the type of the crusher used in the underground of the coal mine is different due to different production conditions and production capacities of various mines. Of which jaw crushers and hammer crushers are most used.

Chinese utility model patent publication No. CN206082770U discloses a screenable multistage crushing machine, which can crush coal blocks of different sizes, and has good continuous crushing performance and uniform particle size of crushed products, but when the crushing process is blocked, the main shaft of the crushing machine is damaged under strong driving, so that the main shaft of the crushing machine is easily damaged.
