Coke cutting machine

Abstract

The invention discloses a coke cutter which comprises a rack, a motor, a gearbox, a coke cutting box, a bearing pedestal set, a master coke cutting roller and a slave coke cutting roller. The motor, the gearbox, the coke cutting box and the bearing pedestal set are arranged on the rack. The master coke cutting roller and the slave coke cutting roller are arranged in the coke cutting box in parallel through the bearing pedestal set. The motor is in transmission connection with the gearbox, and an output shaft of the gearbox is in transmission connection with the master coke cutting roller. The master coke cutting roller and the slave coke cutting roller each comprise a roller shaft, a plurality of pull rods, a roller shaft sleeve arranged on the roller shaft through an end sleeve, a plurality of gear rings arranged on the roller shaft sleeve, spacer rings arranged at the positions, between the adjacent gear rings, of the roller shaft sleeve, and end discs arranged at the positions, on the outer sides of the gear rings at the two ends, of the roller shaft sleeve. The end discs, the gear rings and the spacer rings are in fastened connection through the pull rods and pull rod nuts. Each gear ring comprises a disc-shaped gear ring disc body and a plurality of main cutter teeth evenly distributed on the periphery of the gear ring disc body. Slope faces are formed on three sides of the main side face of each main cutter tooth, and the contact position of every two adjacent slope faces is of a corner angle structure. The gear rings of the master coke cutting roller and the gear rings of the slave coke cutting roller are staggered, and the coke cutter is good in coke cutting quality.

Description

technical field [0001] The invention relates to the technical field of crushing equipment, in particular to a coke cutter. Background technique [0002] At present, commercially available coke is a large block structure with irregular shapes and sizes, which cannot be directly used in industrial production. In the process of industrial production, lump coke needs to be further pulverized and processed into coke raw materials with a certain particle size to meet the needs of industrial equipment, such as metallurgical equipment. [0003] The wolf tooth crusher is a kind of coke crushing equipment, but it has the technical problems of high powder extraction rate and easy damage to the equipment itself. Aiming at the above-mentioned problems of the wolf-tooth crusher, a coke cutter adopts a toothed cutter clamped on the roller shaft, and the roller shaft drives the cutter to rotate to realize the cutting of coke lumps. For example, the Chinese patent document whose publicatio...

Problems solved by technology

However, the cutting blade of the existing coke cutting machine, that is, the knife tooth, is in surface contact with the material during coke cutting, and the cutting resistance is relatively large. At the same time, the cutting blade wears quickly, and the cutting blade often breaks. Coke materials are often jammed between two adjacent cutting blades, which affects the cutting efficiency and cutting quality of coke
