[0002] Cone crusher is a kind of crushing machine suitable for raw materials in metallurgy, construction, road construction, chemical and silicate industries. According to different crushing principles and different product particle sizes, it is divided into many models. Cone crusher has large crushing ratio, high efficiency, low energy consumption, uniform product particle size, suitable for medium and fine crushing of various ores and rocks. Its models are mainly divided into SMG series, spring type and HPC series.

[0003] Traditional cone crushers, including Simmons spring cone crusher, multi-cylinder cone crusher, etc., have an open lubrication system. The lubricating oil leaks out directly from the wrist-shaped bearing as the moving cone swings.

[0004] During actual use, if the lubrication flow is not well controlled, a large amount of lubricating oil will leak directly to the outside, causing lubricating oil loss and environmental pollution. In addition, since the lubrication channel is directly connected to the external environment, a breathing effect is produced as the main shaft moves, and a large amount of dust enters the lubrication system to contaminate the lubricating oil, reducing the use time of the lubricating oil and affecting the use of the machine. For this reason, the present application provides an oil leakage and dust prevention structure on a cone crusher. Utility Model Content

[0035] When in use, first start the equipment to crush the material. During the crushing process, the main shaft 4 and the crushing wall 5 will rotate. In order to ensure smoother rotation, the lubricating oil is injected into the main shaft groove 3 through the oil inlet pipe 12. After the lubricating oil enters the main shaft groove 3, the rotation of the main shaft 4 and the guide rod 6 will guide the excess lubricating oil into the drainage groove 7. The lubricating oil is collected into the transfer groove 8 through the inclined drainage groove 7, and then recovered into the recovery chamber 10 through the inclined chute 9.

When the filter 147 needs to be replaced, the L-shaped plate 1492 can be pulled to move inside the sliding groove 1491, so as to drive the bottom block 1493 away from the groove on the clamping block 148, so that the block 1493 is separated from the clamping block 148. When the block 1493 is separated from the clamping block 148, the shell 2 144 can be separated from the shell 1 141 to quickly replace the internal filter 147;

When the clamping block 148 is inserted into the clamping groove 149, the L-shaped plate 1492 can be loosened, and the clamping block 1493 will be driven to re-enter the clamping groove of the clamping block 148 according to the rebound of the spring 1494, thereby completing the quick connection between the shell 1 141 and the shell 2 144, and the filter 147 can be replaced more quickly and conveniently. In addition, the air flow can be directly blown into the lubricating oil circuit through the ventilation pipe 16, so that the air flow blows from the inside to the outside, so that the dust generated during the operation of the equipment cannot enter the lubricating oil circuit.
