Description

Technical Field

[0001] The utility model relates to the technical field of crushers, in particular to a speed regulating and anti-blocking device for crushers. Background Art

[0002] Crusher is a material crushing device, which is widely used in metallurgy, mining, chemical industry, cement and other industries. In many industries, there are a large number of raw materials and recyclable waste materials that need to be processed by crushers, and the raw materials need to be crushed into the particle size required by the next step of operation by crushers. According to the principle of crushing, crushers can be divided into impact crushers, hammer crushers, jaw crushers, roller crushers, compound crushers, etc. Among them, hammer crushers are a more typical crusher.

[0003] However, existing crushers are generally blocked during use, especially at the feeding and discharging locations. When feeding, a feeding funnel that is wide at the top and narrow at the bottom is generally used to assist in feeding. When there are a large number of coal blocks, the coal will often be blocked at the feed port of the crusher, resulting in failure to feed normally; when discharging, the crushed coal will fly out along the tangent direction of the rotating crushing hammer, forming an angle approximately right with the side wall of the discharging funnel, first falling on the side wall of the discharging funnel, and then falling down along the side wall of the discharging funnel to discharge. It is very easy for coal to stick to the side wall of the discharging funnel, gradually accumulating and causing blockage, making it impossible for the entire coal feeding system to operate normally.
