Abstract
The invention relates to a double-roller crusher. The double-roller crusher comprises rollers and a plurality of toothed plates. Each roller comprises a roller body. The toothed plates are fixed to the surfaces of the roller bodies. Each toothed plate comprises a positioning column, a plate seat and a tooth, wherein the positioning column is fixedly connected with the bottom of the plate seat and is in a circular truncated cone shape, and the diameter of the upper bottom face of the positioning column is larger than the diameter of the lower bottom face of the positioning column. A plurality of tooth installation grooves are formed in the surface of each roller body in the axial direction of the roller body, the bottom of each tooth installation groove is provided with a plurality of positioning holes used for positioning the corresponding tooth in the radial direction of the roller body, each positioning hole is in a circular truncated cone shape, the diameter of an upper opening of each positioning hole is larger than the diameter of a lower opening of the positioning hole, the upper openings of the positioning holes are formed in the bottoms of the tooth installation grooves, and the bottoms of the tooth installation grooves are further provided with a plurality of connection holes. The positioning columns are installed in the positioning holes. Fastener holes are matched with the connection holes. The double-roller crusher is reasonable in structural design, firm, reliable in performance and long in service life.
Description
technical field [0001] The invention relates to a double-roll crusher, which belongs to the field of crushers. Background technique [0002] The toothed rollers in the existing double-roller crusher are worn out during long-term use, resulting in high maintenance costs and maintenance time. The production cycle of the toothed rollers is about 10 to 20 days. Therefore, a double-roller crusher The production cycle is about one month. And once the toothed roller wears out, it is necessary to replace the roller body, which brings greater economic loss. [0003] Chinese patent 201410353652.3 discloses a toothed roller for a plug-in tooth crusher with an interlocking mechanism and a pressing shear blade, which includes a plurality of hollow roller bodies, and multiple rows of tooth handles are respectively arranged on the outer circular surfaces of the plurality of hollow roller bodies A plurality of roller teeth are respectively inserted in the holes of the multi-row tooth shan...
