Cereal classifying and separating mechanical device beneficial for removing impurities

Abstract

The invention discloses a cereal classifying and separating mechanical device beneficial for removing impurities. The mechanical device comprises a bottom frame, an impurity removal separating bucketand a first screening cavity. The left side of the upper surface of the bottom frame is fixedly connected with a feed device through a connecting frame. The lower side of the impurity removal separating bucket is fixedly connected to the middle of the upper surface of the bottom frame through a connecting frame. An impurity removal block is arranged on the outer side of the lower side of an impurity removal connecting pipe. A connecting block is fixedly connected with the upper side of a light impurity discharge port. A heavy material guide plate is arranged on the lower side of a heavy graindischarge port. By means of the cereal classifying and separating mechanical device, feeding can be conveniently and uninterruptedly conducted with lower efforts, work efficiency is improved, the workdifficulty is lowered, different types of impurities can be conveniently removed, and cereal can be separated into different sizes to be collected.

Description

technical field [0001] The invention relates to the related technical field of general machinery, in particular to a grain grading and separation mechanical device that facilitates the removal of impurities. Background technique [0002] General machinery refers to mechanical equipment with strong versatility and wide range of uses. Commonly used are drying equipment, motors, pumps, separation machinery, etc. Separation machinery refers to substances with different physical and chemical properties in the mixture, according to their particle size, It is an operation process to separate substances according to different characteristics such as phase, density, solubility, boiling point, etc. The separation device is widely used in chemical industry, metallurgy, coal, dyestuff, food, brewing and other fields. Grain is almost used in our daily life. For edible food, after the grain is harvested and dried in the planting area, there will often be some impurities such as dust, fall...
