Crushing beam combined structure of double-tooth roller crusher

Abstract

The invention discloses a crushing beam combined structure of a double-tooth roller crusher applied in the industry of crushing equipment. The structure consists of a rack, an adjusting gasket, a bolt, a crushing beam, a crushing tooth cap, a tooth cap cover, a guide element, a stop block, a bolt for the stop block, and a bolt; a crushing beam assembly of the double-tooth roller crusher is positioned below two crushing tooth rollers of the crusher, and the crushing beam assembly is assembled on the rack through the bolt; two ends of the crushing beam are provided with a guide groove C and a guide groove D respectively; the guide element is arranged on the rack; the crushing beam assembly is placed on the rack along the guide groove C and the guide groove D and assembled through the bolt; and the adjusting gasket is provided with a plurality of U-shaped grooves, the opening directions of the U-shaped grooves and the side of the adjusting gasket from inclination angles, and the sides of the inclination directions of the U-shaped grooves are provided with unfilled corners parallel to the opening directions of the U-shaped grooves, so that the adjusting gasket is obliquely inserted into the long and narrow space more deeply. The guide structure of the crushing beam of the device is simple, so that the crushing beam assembly is convenient to install; and by combining the adjusting gasket structure with large bearing area, the stress state of the crushing beam assembly is effectively improved.

Description

Technical field: [0001] The invention relates to a broken beam combination structure of a mine crusher, in particular to a broken beam combined guide structure, an adjusting gasket structure capable of increasing the bearing area, and a broken tooth cap bolt groove of the broken beam which can be easily disassembled structure and a fastening structure to increase the bearing capacity of the broken tooth cap of the broken beam. Background technique: [0002] Double-toothed roller crusher is a new type of crushing equipment that has appeared abroad in recent years. This type of crusher can crush materials twice to ensure that the output particle size is qualified. The primary crushing is that the crushing teeth on the two toothed rollers bite and crush the material, and the crushed material is discharged from the gap between the teeth of the toothed rollers. The material whose particle size is still too large is blocked by the crushing beam. When the crushing tooth on the cru...

Problems solved by technology

In the above-mentioned prior art, due to the large combined mass of the crushing beam, it is very difficult to align the bolt holes during installation; when the crushing teeth of the toothed roller and the crushing tooth cap interact with the crushed material, a large force is generated, which can only be borne by the bolts at both ends of the crushing beam. , and due to the compact structure and small space of the inner cavity of the crusher, the bearing area of ​​the adjusting gasket in the existing structure is very small, so the combination of the broken beam and the frame is not firm.

The crushing tooth cap and the crushing beam are connected by bolts, and the crushing tooth cap is independent of each other. When the crushing tooth cap and the crushing roller crush the material, a large force is generated, which makes the crushing tooth cap have a tendency to reverse and crush Tooth cap under stress is not good

Since the closing bolt of the crushing tooth cap can be rotated, when the crushing tooth cap is disassembled, the tooth cap welded on the crushing tooth cap must be removed first. After the crusher is assembled, the structure is relatively compact and the disassembly space is small, so the whole The tooth roller is disassembled, and then the tooth cap welded on the crushing tooth cap is removed to disassemble the crushing tooth cap, which leads to long maintenance time and affects production efficiency
