Internal explosion-proof device for high-safety jaw crusher

Abstract

The invention provides an internal explosion-proof device for a high-safety jaw crusher. Transmission rods are slidably mounted in the left end and the right end of a jaw plate wheel, and rotatably mounted in frame seats; spring seats are fixedly mounted on the outer surfaces of the frame seats, and bevel gear rods penetrate through the upper surfaces and the lower surfaces of the frame seats; push rods are attached to the inner side surfaces of the frame seats, and telescopic bags are attached to the tops of the push rods; discs are meshed with the top ends of the bevel gear rods; when the dust amount in the crusher body reaches the maximum, dust is absorbed through the telescopic bags, and then the push rods are pushed to move; the frame seats are extruded by the push rods to move outwards; therefore, the transmission rods are driven to move, and then meshed with the bevel gear rods; then, the bevel gear rods are driven to rotate together; when the dust amount is gradually reduced, the frame seats are moved inwards through the spring seats, and therefore the transmission rods are separated from the bevel gear rods; and thus, the purpose of automatically avoiding dust explosion according to the internal dust amount is achieved.

Description

Technical field [0001] The present invention belongs to the technical field of jaw crusher, and in particular, an internal explosion-proof device for high safety jaw crusher. Background technique [0002] The jaw crusher is commonly known as a crushing cavity, an analog animal, and the crusher of the mine smelting, building materials, roads, railways, and railways. In the various industries, various ores and large amounts of dust produced in material crushing, and the risk of dust explosions is prone to dust, requiring specific devices. [0003] In the traditional jaw crusher, when the internal dust is too much, the safety hazard is high, and the dust explosion cannot be avoided according to the internal dust while breaking. At the same time, after crushing, the jaw crusher often causes clogging phenomenon, separation It is not effective, so in view of this, it is important for existing structures and deletions to improve the internal explosion-proof device for high-security Jaw ...

AI Technical Summary

Problems solved by technology

[0003] In the traditional jaw crusher, when the amount of internal dust is too much, the potential safety hazard is high, and it is impossible to automatically avoid dust explosion according to the amount of internal dust during crushing. At the same time, after crushing, the jaw crusher often causes blockage and separation. The effect is not good, so, in view of this, the existing structure and defects are researched and improved, and the internal explosion-proof device for the high-safety jaw crusher is provided, in order to achieve the purpose of having more practical value
