An ore sorting and crushing device

Abstract

The invention discloses an ore separating and crushing device. A separating plate is arranged at the lower end of an ore inlet; the left end of the separating plate is rotationally connected with theside wall of a device body; the lower end of the separating plate is hinged to the upper end of a connecting rod; the lower end of the connecting rod is hinged to the right end of a sliding block; theleft end of the sliding block is glidingly connected with a guide groove; the lower end of the sliding block is fixedly connected with the upper end of a threaded rod; the lower end of the threaded rod is in threaded connection with a threaded sleeve; the upper end of the threaded sleeve is sleeved with the right end of a transverse support rod; the left end of the transverse support rod is fixedly connected with the side wall of the device body; a bearing at the bottom of the threaded sleeve is rotationally connected with the device body; and the lower end of the threaded sleeve is fixedly connected with a large gear. According to the device, the bottoming function is used through cooperation of the threaded rod and the threaded sleeve, the separating plate swings up and down in a reciprocating manner to realize intermittent feeding, a No.1 motor drives a rotating roller through a bevel gear group to rotate to crush ore, and then the crushed ore is separated by the aid of a sieve plate and a fixed filter plate. The device is reasonable and applicable in structural design and high in connection rigidity, the ore separating and crushing quality is greatly improved, and the production efficiency is accelerated.

Description

technical field [0001] The invention relates to a mining machine, in particular to an ore sorting and crushing device. Background technique [0002] Any natural aggregate of minerals in the earth's crust, under the condition of modern technical and economic level, from which metals or other mineral products necessary for the national economy can be extracted on an industrial scale, is called ore. [0003] The stones containing some valuable minerals mined from the mine can be used in metal mines, metallurgical industry, chemical industry, construction industry, iron (road) road construction units after crushing and grinding. In engineering fields such as cement industry and sand and gravel industry, ore is generally composed of ore minerals and gangue minerals. Ore minerals refer to metal or non-metallic minerals that can be utilized in ores, also known as useful minerals. Such as chromite in chromium ore, chalcopyrite, bornite, chalcocite and malachite in copper ore, asbe...

AI Technical Summary

Problems solved by technology

[0004] At present, most of the existing ore crushing and screening devices have complex structures, high maintenance and use costs, and do not have the function of intermittent feeding, and the screening effect is not good.
