Description

Technical Field

[0001] The utility model relates to the technical field of removing hanging materials from a four-shaft crusher, in particular to a fixed knife structure used for removing hanging materials from a knife body of a four-shaft crusher. Background Art

[0002] The four-shaft crusher consists of two sets of upper and lower knife rollers. The upper and lower knife rollers on the same side and the two lower knife rollers cooperate to shear the materials, and the materials are crushed to the size that can pass through the filter.

[0003] When the crushed material is straw stalks or similar materials, especially when the material itself contains a certain amount of moisture, the crushed material is easy to stick to the knife roller and accumulate more and more with the reciprocating rotation of the knife roller, thereby affecting the feeding speed of the new material, and finally causing the crusher load to increase and the efficiency to decrease. Utility Model Content

[0004] The utility model aims to provide a fixed knife structure for removing material hanging on the knife body of a four-axis crusher, so as to solve the problems existing in the prior art, reduce the stickiness of materials during use, and ensure a stable material feeding speed and crushing efficiency.

[0005] In order to achieve the above purpose, the solution of the utility model is:

[0006] A fixed knife structure for removing material hanging on the cutter body of a four-axis crusher comprises a filter seat, a filter, a scraper and a fixed knife block; the upper depression of the filter seat forms a groove providing space for the four cutter rollers of the four-axis crusher to rotate, and the cross section of the groove is two pairs of first circular arcs and second circular arcs that are mirror-symmetrical; the filter is laid in the groove; the scraper is arranged on the line connecting the proximal ends of the two second circular arcs, and its two sides are tangent to the lower cutter roller of the four-axis crusher; the fixed knife blocks are arranged at equal intervals on the line connecting the second circular arc and the first circular arc on the same side, and a spacing for the clearance of the blade of the upper cutter roller to cooperate is reserved between adjacent fixed knife blocks.

[0007] Both sides of the filter seat are provided with foot seats for fixing the filter seat on the frame of the four-shaft crusher.

[0008] The fixed blade structure for removing material hanging from the blade of the four-shaft crusher further comprises a mounting bar arranged along the line connecting the second circular arc and the first circular arc on the same side, and the fixed blade blocks are arranged at equal intervals on the mounting bar.

[0009] Preferably, the mounting strip is locked onto the filter seat by a plurality of bolts.

[0010] After adopting the above technical solution, the utility model has the following technical effects:

[0011] The utility model arranges a scraper bar and a fixed knife block on the filter seat. When the upper and lower knife rollers rotate, the fixed knife block can scrape off the materials adhering to the side edge of the blade of the upper knife roller, and the scraper bar can scrape off the materials adhering to the peripheral surface of the blade of the lower knife roller, thereby reducing the adhesion of materials during the use of the four-axis crusher and ensuring a stable feeding speed and crushing efficiency.
