Suction specific gravity stone removal combined grain cleaning machine

Abstract

The invention provides a suction-type specific gravity de-stoning combined grain cleaner. Wheat passes through a first layer of cleaning sieve, and impurities larger than the wheat are discharged out of a shell through a large slag outlet. The wheat penetrates through the bottom of the first layer of cleaning sieve to enter a second layer of cleaning sieve, and fine sand smaller than the wheat is discharged out of the shell through a fine sand channel. The cleaned wheat flows into a third layer of material distribution sieve. The third layer of material distribution sieve and a fourth layer of stone collecting sieve communicate with a low-pressure air hose and a dust catcher to form an air flue. Air draft is performed inside the shell under the wind action of a low-pressure fan, and airflow penetrates through the sieving material layer of the fourth layer of stone collecting sieve and the sieving material layer of the third layer of material distribution sieve from bottom to top to make the wheat suspend. Under the combined action of the airflow and sieve body vibration, the wheat penetrates through sieve pores to be evenly distributed on the surface of the fourth layer of stone collecting sieve, and heavy stones of approximately the same size are discharged from a stone outlet in the upper end of the sieve surface. By means of the suction-type specific gravity de-stoning combined grain cleaner, the defects existing in other grain cleaners are overcome, meanwhile, labor and pollution to the ambient environment are reduced, and the combined grain cleaner is suitable for small and medium size grain processing enterprises and matching equipment for processing materials supplied by clients.

Description

technical field [0001] The invention belongs to the field of wheat impurity cleaning machinery and equipment, and in particular relates to a suction-type specific gravity stone-removing combined grain cleaning machine. Background technique [0002] At present, the wheat grain cleaning machine for small flour processing equipment on the market, in the cleaning process, the impurities larger and smaller than wheat are cleaned through the coarse sieve and fine sieve, and then the stones are removed by the stone remover, and the wheat is moistened after threshing. Can be done. The cleaning process is not operated in a closed state, dust and wheat husks are flying everywhere, affecting the surrounding environment and the health of operators. Due to the poor cleaning effect, the cleaned wheat still contains dust, wheat husks and small stones, which cannot meet the requirements of flour processing. standard. Contents of the invention [0003] The technical problem to be solved ...
