Adjusting mechanism capable of adjusting buffering power for hammer crusher

Abstract

The invention discloses an adjusting mechanism capable of adjusting buffering power for a hammer crusher. The adjusting mechanism comprises a material receiving box, a crushing box, a belt wheel, a transmission roller and a crushing device, wherein the crushing box is arranged at the upper part of the material receiving box; a transmission roller is fixedly connected to the outer side of the transmission shaft, a buffer force adjusting device is fixedly connected to the outer side of the transmission roller, and the buffer force adjusting device and the crushing device are all positioned in acrushing roller; the buffer force adjusting device comprises fixing sleeve pipes, wherein pressure buffer springs are arranged at the bottoms of the inner sides of the fixing sleeve pipe, spherical sliding blocks are arranged on the upper parts of the pressure buffer springs, the upper end surfaces of the sliding blocks are fixedly connected to telescopic rods, and shear thickening liquids are further filled in the fixing sleeve pipes; and side an edge anti-leakage plate is arranged on the two sides of the crushing roller, and a planetary gear is arranged at the center of the side edge anti-leakage plate. The adjusting mechanism has the advantages that the crushing effect is good, crushing is uniform, blockage is not prone to occur, the pressure can be automatically adjusted, and the service life of the device can be prolonged.

Description

technical field [0001] The invention relates to the field of mechanical equipment, in particular to an adjustable buffer power adjustment mechanism for a hammer crusher. Background technique [0002] Crusher is also called stone crusher, and stone crusher can be divided into medical stone crusher and mining stone crusher according to major categories. In principle, the mining rock crusher is suitable for crushing a large number of hard rocks in mines. Its typical granite output particle size is ≤40mm, which accounts for 90%. The crushing ratio is large, and the crushed material is in the form of cubic particles. Mining crushing machinery refers to the crushing machinery in which the particle size greater than 3 mm in the discharge accounts for more than 50% of the total discharge. The hammer crusher is a crusher for crushing materials with a maximum particle size of 600-1800 mm to 25 mm or less. The hammer crusher is suitable for crushing medium-hard materials in industri...
