Ore crushing and dust collection device

Abstract

The invention discloses an ore crushing and dust collection device. The right end of a driving motor is rotatably connected with a sleeve shaft. The right end of the sleeve shaft is in sleeved connection with a stepped shaft. The right end of the stepped shaft is fixedly connected with a first lead screw. The first lead screw is connected with a sleeve. The right end of the first lead screw is rotatably connected with a movable plate through a bearing. A guide groove is slidably connected to the upper end of the movable plate. The left and right ends of the lower portion of the movable plate are slidably connected with sleeve plates correspondingly. The two ends of the first lead screw are fixedly connected with semicircular bevel gears correspondingly. Tooth parts of the semicircular bevel gears are engaged with a bevel gear. The bevel gear is fixedly connected with the upper end of a driven shaft. The middle of the driven shaft is rotatably connected with the movable plate through abearing. The ore crushing and dust collection device conducts crushing on ores on the inclined bottom of a device body through a rolling drum. Dust generated in the crushing process is sucked into a dust collection chamber for collection to prevent the situation that flying dust is generated, pollutes the environment and damages health of working staff. Moreover, an arc plate rotates to achieve intermittent discharging to prevent excessive ores at the bottom of the device body from damaging the rolling drum due to excessive working load, and meanwhile, the crushing effect is improved.

Description

technical field [0001] The invention relates to a mining machine, in particular to an ore crushing and dust collection device. Background technique [0002] Ore refers to mineral aggregates from which useful components can be extracted or which have certain usable properties, and can be divided into metallic minerals and non-metallic minerals. The ore needs to be mined from the mine and processed step by step by crushing and grinding, and then it can be used in engineering fields such as metal mines, metallurgical industry, chemical industry, construction industry, railway, highway and other construction units, cement industry and sand and gravel industry. [0003] At present, most of the existing ore crushing and grinding devices do not have the function of dust reduction. During the crushing process of ore, large dust is often generated, which is not conducive to environmental protection and will damage the health of the staff. Other auxiliary equipment is required during ...

Problems solved by technology

[0003] At present, most of the existing ore crushing and grinding devices do not have the function of dust reduction. During the crushing process of ore, large dust is often generated, which is not conducive to environmental protection, and will damage the health of the staff. Other auxiliary equipment is required during the crushing process. Mechanically add materials to the crushing device continuously or intermittently, the structure is complex, the work efficiency is not high, the load of the crushing device is high, and the crushing effect is not good
