Abstract

PURPOSE:To make the extraction of a shutter easily as well as to facilitate cleaning inside an elevating case, by installing a shutter can which makes the shutter adhere to a bottom port and closes it at a insert process terminal part of the shutter opening or closing the elevating case bottom port. CONSTITUTION:A U-shaped shutter 4 opening or closing a bottom port is installed in the bottom of an elevating case 3 free of insertion. And, in an outer circumferential part of a bottom end of the elevating case 3, there is provided with a U-shaped shutter receiving plate 27 which receives the shutter 4. An upper edge of a projecting wall 25 of this shutter receiving plate 27 is formed into a shutter can part 5 made to come into a gradually up-grade state at a terminal part from an insert process starting end of the shutter 4. Therefore, when the shutter 4 is inserted thereinto, it is lifted up at an insert process terminal part and made to adhere to a bottom opening and closed. Then, it is joined to the receiving plate 27 by a lock bar 29. With this constitution, extraction of the shutter 4 becomes facilitated, thus cleaning for the inside of the elevating case at the time of selecting grain types comes easy.

Description

DETAILED DESCRIPTION OF THE INVENTION Field of Industrial Application This invention relates to a grain lifting device for a grain raising machine, and can be used as a grain removing device for a grain raising machine such as a grain dryer or a huller.

Conventional technology In the past, a shutter for opening and closing the bottom opening was inserted into the bottom of the grain hoisting case housing the bucket/conveyor belt for conveying grains. A residual grain removal device was formed in close contact with the bottom of the grain raising case.

Problems to be Solved by the Invention In the residual grain removal device of a grain raising machine used in a dryer for drying grains, when grains to be dried are supplied into this grain raising machine, a bucket that is rotatably driven within this grain raising machine is used. On the conveyor belt
The supplied grains are conveyed to the upper part and supplied to the storage chamber of the dryer, and are repeatedly circulated from this storage chamber to the lower drying chamber to dry the grains. , when changing from paddy grains to wheat grains, etc., a! ! , the shutter that opens and closes the bottom opening at the bottom of the grain raising case of the grain raising machine is pulled out from the bottom so that the bottom mouth of the grain raising case is opened, and the inside of the grain raising case is opened from this opened bottom opening. The remaining rice grains are discharged outside the machine, and this! The inside of the grain case is cleaned, but during this cleaning, the entire surface of the shutter is in close contact with the bottom of the grain raising case, so if this contact is poor, the shutter and the bottom of the grain raising case may In some cases, grains get stuck between the shutters, making it difficult to remove the shutter.
A shutter cam (5) that tightly closes the bottom opening at the end of the insertion stroke where a shutter (4) for opening and closing the bottom opening is inserted into the bottom of the grain raising case (3) in which the belt (2) is installed.
The structure of the residual grain removal device of a shell lifter is provided with the following.

Effect of the Invention For example, when the grain raising machine residual grain removal device of the present invention is used in a dryer for drying grain, when the grains to be dried are supplied into the grain raising machine, the rotation drive occurs within the raising machine. The supplied grains are conveyed to the upper part by the bucket conveyor (1) and belt (2), and are supplied into the dryer, but when the type of grain to be dried changes from paddy grains to wheat grains, In this step, the shutter (4) for opening and closing the bottom opening at the bottom of the grain raising case (3) of the grain raising machine is removed from the bottom of the grain raising case (3), and the bottom opening at the bottom of the grain raising case (3) is opened. The remaining rice grains in the grain raising case (3) are discharged from the machine through this opened bottom port, and the cleaning of the inside of the grain raising case (3) is completed.

When the shutter (4) is inserted into the bottom of the grain raising case (3) and inserted to the end of the insertion stroke, the shutter (4) is brought into close contact with the bottom of the grain raising case (3) by the shutter cam (5). Then, the bottom opening at the bottom of the grain raising case (3) is closed with the shaft (4).

Effects of the Invention According to the present invention, at the end of the insertion stroke where the shutter (4) for opening and closing the bottom opening at the bottom of the grain raising case (3) of the grain raising machine is inserted, this shutter (4) closes the grain raising case (3). ) Since the shutter (4) comes off from the shutter cam (5) when the shutter (4) is pulled out, this shutter (
By creating a predetermined gap between 4) and the bottom of the grain raising case (3), the shutter (4) can be easily pulled out and the inside of the grain raising case (3) can be easily cleaned. .
