Roller screen type stone extractor for separating soil and stone

Abstract

The invention discloses a soil-stone separation roller screen stone extractor, which comprises a frame, wherein the inside of the machine frame is provided with a delivery hopper, a storage hopper and a stone outlet groove; a roller shaft is arranged above the delivery hopper; a plurality of rotary discs are uniformly arranged on the roller shaft which is provided with soil crushing knifes through the rotary discs; a fixed rack for fixing a movable swinging arm is arranged on the left of the roller shaft; the movable swinging arm consists of a horizontal section and a swinging section which is inclined downwards; a frame top shell is arranged on exteriors of the movable swinging arm, a spring and the roller shaft; a feed hopper is arranged on a top plate of the frame top shell and positioned above the roller shaft and the swinging section of the movable swinging arm; a roller screen is inclined above the storage hopper; a left opening of the roller screen is communicated with the delivery hopper, and a right opening of the roller screen is communicated with the stone outlet groove; and the roller shaft and a second drive unit are connected with a first drive unit and a second drive unit respectively. The soil-stone separation roller screen stone extractor has the advantages of compact structure, good stone removal effect, high work efficiency and low cost.

Description

technical field [0001] The invention relates to a stone removing machine for removing stones and other hard impurities in brick-making raw material soil, in particular to an earth-rock separating rolling screen type stone removing machine. Background technique [0002] At present, the stone removal equipment in the brick and tile production industry is mainly an ordinary rolling screen stone removal machine. Ordinary roller sieve stone remover has the following disadvantages: when it screens out stones, it discharges the soil larger than the sieve hole together with the stones, resulting in waste of resources; on the other hand, when the water content in the raw soil is too large , that is, when the clay is too wet, a snowball effect is formed in the sieve body, which often causes interruption of production. Contents of the invention [0003] The technical problem to be solved by the present invention is to provide an earth-rock separation rolling screen type stone remove...
