Description

[Detailed description of the invention] Fields of use for Jr industry J2 This invention relates to a grain dryer.

Conventional technology In the past, the lower parts of the left and right wall plates forming the storage chamber were inclined inward, and the inclined edges were fixed to the upper edge of the ventilation mesh plate forming the drying chamber. I! It was a device that was brought into contact with the

Problems to be Solved by the Invention A grain dryer that dries grains stored in a storage chamber by flowing hot air generated from a burner into the drying chamber while flowing the grains from this storage chamber to a lower drying chamber. In this case, when the grains to be stored and dried in the storage chamber have a high moisture content, or are particularly wheat grains, the drying chamber is tilted inward from the vertical portions of the left and right wall plates forming the storage chamber. The pressure of the grains on the slope that connects to the ventilation mesh plate that forms is large, and this is why this! The flow resistance of the grains flowing down the slope t''6 becomes large and may become stagnant, resulting in poor circulation. In such a state, the grains may become patchy dry.

Means for Solving the Problems The present invention stores grains in a drying chamber (1) with two or more rows in which the grains are ventilated and dried while flowing down (1). The storage chamber (2) is formed by the front and rear wall plates (3), (3) and the left and right wall plates (4), (4) divided into upper and lower parts, and the lower left and right wall plates (4), (4) on the upper side. is inclined toward the inner drying chamber (1) and connected to the outer ventilation net plate (5) forming this drying chamber (1), and a mountain-shaped In addition to providing and connecting the tilting plate 1 (6), the left and right wall plates (4) on the 1- side are connected with the left and right wall plates (4) on the 1- side using the lower inclined lower edge of the lower part of the plate (4) as a pivot point. ) and (4) are provided rotatably inward.

Effect of the Invention The grains stored in the storage chamber (2) are transferred from the storage chamber (2) into the lower drying chamber (1) through the left and right wall plates (4), (4) the lower sloped part and the sloped plate ( 6) While guiding the flow down,
The hot air generated by the burner passes through the drying chamber (1) to dry the grains, but if the grains to be dried have a high moisture content, and especially when drying wheat grains, the left and right wall plates (4), (4) inward to adjust the angle of the slope of the left and right wall plates (4), (4)'F section to a steep angle, so that the grains flowing down the slope can be adjusted to a steep angle. dry the grains.

Effects of the Invention According to the present invention, the left and right wall plates (4), (4) that guide the grains from the storage chamber (2) to the drying chamber (1) are configured to be freely rotatable inward. Even when the grains to be dried are wheat grains and have a high moisture content, by rotating the left and right wall plates (4) inward, the left and right wall plates (4),
(4) The angle of the lower slope becomes steeper, which improves the flow of grains on this slope, so the grains do not stagnate and have poor circulation; does not cause patchy dryness.
