Description

DETAILED DESCRIPTION OF THE INVENTION Field of the Invention The present invention relates to a grain coarser that efficiently separates grains containing contaminants.

Conventional technology and its problems With the spread of mechanized agriculture, a considerable amount of coarse impurities such as vinyl string, straw waste, wood chips, and stems have been mixed into the harvested raw material grains. When directly supplied to a processing machine, contaminants often stay or get caught in the flow path of the processing machine, closing the flow path and preventing uniform flow, significantly reducing the efficiency of the processing process. This has harmful effects.

This type of rough separator (see Fig. 4) has a porous wall sorting tube 32 with a large number of through holes 31 on its outer circumferential surface mounted horizontally so as to be rotatable, and a guiding blade installed inside the sorting tube 32. A structure is known in which a wheel 33 is fitted and rotated, and a grain feeding section 37 is provided between the sorting tube and the supply hopper 34 provided on the upper part thereof, and the grain feeding section 37 has an am-shaped mesh body 36 placed on a grain flow plate 35. This coarse separator allows the grains mixed with coarse contaminants to flow down from the supply hopper 34 to the comb-like mesh 36 to separate coarse contaminants such as vinyl strings and stems, and also removes the contaminants. The elastic force of the net body 36 discharges the objects near the upper end surface of the sorting tube 32, and small foreign objects such as grains, straw waste, and wood chips that pass through the grooves of the net body 36 and fall onto the sorting tube 32. While flowing down near the side, the rotation of the sorting cylinder 32 rotates the foreign matter along the circumferential surface of the cylinder and discharges it forward.
The grains are collected in the cylinder by passing through the through holes 31 of the grains, and are guided to the bottom of the sorting cylinder 32 while being placed on the blades by the rotation of the impeller 33, passing through the through holes 31 at the bottom of the sorting cylinder 32. A configuration is known in which the grains are air-selected by a wind-selecting device, and then flow down onto the surface of an inclined perforated plate 38 provided at the bottom to sort out the grains to ensure fine selection and regularization. In the sorting cylinder, the grains flow into the cylinder through holes in the porous wall and are guided by the impeller and discharged through the holes in the bottom of the porous wall for sorting, so the size of the sorting cylinder is extremely large. It is inconvenient to transport, assemble, and install the entire device, and the rotating blades cause damage to the grains, and the operation is often interrupted to clean the sorting cylinder of foreign matter inserted into the through hole, reducing sorting efficiency. This had problems such as a decrease in

Purpose of the Invention In view of the above-mentioned points, the present invention has been developed by installing a non-porous wall sorting tube with a plurality of pot holes on the outer circumferential surface into which the grains are placed, which is rotatably hung horizontally, and which has a grain-flowing container on one side of the upper part of the sorting tube. In addition to providing a regulating body, by providing a coarse impurity discharge device at a lower position, the grains are immersed in the multiple holes of the rotating sorting cylinder and discharged, and the coarse contaminants flowing down through the grain regulating body are removed. By roughly selecting and discharging impurities, the drawbacks of the conventional device consisting of the porous wall sorting tube mentioned above are eliminated, the sorting tube is made smaller, and the transportation, assembly, and installation of the entire device are simplified. , a high-performance grain coarse separator that facilitates the sorting and removal of coarse contaminants and uses pot holes that do not allow coarse contaminants to get stuck in them, ensuring efficient coarse sorting and mass production of selected grains. The purpose is to provide
