Technical Field

[0001] The utility model relates to the field of pulley protection, in particular to a pulley protection device for a multi-cylinder hydraulic cone crusher. Background Art

[0002] Cone crusher is a kind of raw material crushing machine widely used in metallurgy, construction, road construction, chemical and silicate industries. It is suitable for secondary and tertiary crushing in metal mines and construction sand and gravel processing. It has the characteristics of strong crushing ability and large output. It is mostly used for crushing medium-hard materials. The working principle of multi-cylinder hydraulic cone crusher is to use the hydraulic system to provide power and realize the operation of cone crusher by controlling the inlet and outlet of hydraulic oil. During the crushing process, the material enters the crushing chamber from the feed port and is crushed under the action of the conical crushing wall and guide plate. By adjusting the winch equipment and the adjustment sleeve, the size and particle size of the crushing chamber can be controlled to meet different needs, and the belt drive system is an important part of driving the crusher;

[0003] However, in the prior art, the environment in which the crusher is used, such as the ore, has a large amount of gravel flying around, which can easily get into the gap between the pulley and the belt, causing wear of the belt and the pulley. At the same time, the connection gap between the belt and the pulley can easily cause the belt to slide relative to each other, causing accidents such as slipping and wear in power transmission, thus affecting the service life.

[0004] Therefore, a pulley protection device for a multi-cylinder hydraulic cone crusher is proposed to solve the above problems. Utility Model Content

[0005] The purpose of the utility model is to provide a pulley protection device for a multi-cylinder hydraulic cone crusher in order to solve the above-mentioned problem, which improves the problem that the environment in which the crusher is used, such as ore, has a large amount of stone splashing, which is easy to enter between the pulley and the belt, causing wear of the belt and the pulley. At the same time, the connection gap between the belt and the pulley easily causes the belt to slide relative to each other, causing accidents such as slipping and wear in power transmission, thus affecting the service life.

The two push rods 3013 slide through the upper inner wall of the mounting shell 2 and extend downward. The push rods 3013 are fixedly connected to the fitting assembly 4. When it is necessary to adjust the tensioning protection mechanism 3 for downward pressure protection, the lead screw 3011 can be rotated at this time, so that the lead screw 3011 drives The nut 3012 is pressed downward, and the nut 3012 drives the push rod 3013 and the fitting component 4 to descend and fit the belt surface to tension and protect the belt. Two guide frames 3014 are fixedly connected to the upper end of the mounting shell 2, and the two push rods 3013 are slidably connected to the inner walls of the two guide frames 3014 respectively. When the push rod 3013 descends, it is easy to be skewed. At this time, the guide frame 3014 is used to limit the downward pressure of the push rod 3013, so that when the push rod 3013 slides down, it is not easy to be skewed.
