Stone crushing and screening machine for mining engineering

Abstract

The invention discloses a stone crushing and screening machine for mining engineering. A third motor is fixedly arranged in a first motor box, and the output shaft of the third motor penetrates through the top of a gearbox and extends to the interior of the gearbox to be fixedly provided with first gears. The invention relates to the technical field of engineering machinery. According to the stonecrushing and screening machine for the mine engineering, a first roller shaft and a second roller shaft are obliquely arranged, so that large stones which cannot pass through the first roller shaft and the second roller shaft cannot be moved to the front end of the first roller shaft and the front end of the second roller shaft; the second motor drives a first belt wheel to rotate, a belt is usedfor driving a second belt wheel to rotate, and a threaded sleeve is driven to rotate, so that a screw rod drives the first motor box and the gearbox to move downwards; and the third motor drives thefirst gears to rotate, and second gears which are meshed with each other are used for driving the drill bit to rotate at a high speed, so that the large stones are crushed, and the crushed small stones can be crushed through the first roller shaft and the second roller shaft.

Description

technical field [0001] The invention relates to the technical field of engineering machinery, in particular to a stone crushing and screening machine for mining engineering. Background technique [0002] The so-called mining engineering is based on mineral resources, engineering technology for resource mining operations in mines, including ground and underground engineering, ground engineering mainly includes mining machinery and facilities, such as dressing plants, well towers, hoists, compressors Ventilators, etc. Underground engineering includes shaft engineering, chamber engineering and some installation engineering. [0003] Mineral resources are the product of the long-term formation, development and evolution of the earth's crust, and are formed by the accumulation of natural minerals under certain geological conditions and through certain geological processes. Different geological processes can form different types of minerals. According to the geological process o...

Problems solved by technology

[0005] Aiming at the deficiencies of the prior art, the present invention provides a stone crushing and screening machine for mining engineering, which solves the problem that the crusher cannot directly crush some larger stones, and the use has limitations. Multiple devices not only make the operation complicated , It also takes up a lot of space, and a lot of dust will be generated when the stone is broken, which will affect the surrounding environment and even affect the health of the workers.
