Crawler-type grain impurity-clearing machine

Abstract

The invention relates to a crawler-type grain impurity-clearing machine, which comprises a main bracket, and a crawler conveying mechanism, a motor, an air blower, a draught fan, a high-position intercepting device, a mesh sieve plate and a baseplate storage box that are arranged on the main bracket, wherein the conveying tail end of the crawler conveying mechanism is higher than the conveying start end of the crawler conveying mechanism; the air blower and the draught fan are positioned above a crawler, and the air outlet direction of the air blower is opposite to the conveying direction of the crawler; the draught fan is positioned between the conveying start end of the crawler and the air blower, the introduction end of the draught fan faces to the air blower, and the discharge end of the draught fan is connected with an impurity storage bag; the high-position intercepting device is arranged behind the conveying tail end of the crawler and used for intercepting impurities with volume being larger than that of grains, the high-position intercepting device is shaped as a dustpan, the dustpan opening is positioned below the conveying tail end of the crawler, and the inner bottom surface of the high-position intercepting device is provided with a grain circulating channel; the mesh sieve plate is used for filtering impurities with volume being smaller than that of grains and arranged right below the grain circulating channel; the rear end of the mesh sieve plate is lower than the front end of the mesh sieve plate; the baseplate storage box is arranged below the mesh sieve plate, the inner bottom surface of the baseplate storage box is obliquely arranged, and the lowest part of the inner bottom surface is provided with an impurity collecting port, and the impurity collecting port is communicated with an external impurity bag. The crawler-type grain impurity-clearing machine can finish impurity clearing in one step and has high impurity clearing efficiency.

Description

technical field [0001] The invention relates to a mechanical device for cleaning grain. Background technique [0002] At present, most of the cleaning methods for grain are: field dusting method, roller dust blowing method or box type cleaning method. However, the above methods have their own deficiencies. Although the site dust raising method is fast, it cannot complete the cleaning work at one time, and needs to be cleaned later, while the roller dust blowing method and the box type cleaning method not only have low cleaning speed, but also need two. Secondary storage. Therefore, in order to save efficiency and complete the cleaning work at one time on the basis of improving efficiency, we designed and invented a crawler grain cleaning machine. Contents of the invention [0003] The object of the present invention is to provide a crawler-type grain cleaning machine, which can complete the cleaning at one time and has high cleaning efficiency. [0004] The technical so...
