Description

[Detailed description of the invention] Industrial applications This invention relates to a grain dryer.

Problems to be Solved by the Invention In a grain dryer that repeatedly circulates and dries grains while flowing them down from a storage chamber to a drying chamber, the grains flowing down in the drying chamber are exposed to hot air generated by a burner. The drying room is ventilated across the drying chamber and the grains are exposed to the hot air and dried. If the grain is contaminated with a lot of straw waste, the grain may not flow down easily in the four corners of the downstream chamber formed by the sloping wall that guides the grain to the drying chamber, and the grain may become stagnant. , this sometimes resulted in dry spots.

Means for Solving the Problem The present invention provides a storage chamber having a rectangular planar shape for storing grain;
Flow chamber with sloping walls (O) that slope toward the inner lower part to guide the flow into the interior ■ Side walls of these corners (5)
, a corner wall (7) that short-circuits between the side wall (6) and the inclined wall 0.
The structure of the grain dryer is as follows.

Effects of the invention The grains accommodated in the storage chamber (1)
The drying room is reached through the downstream chamber (formed by the inclined wall (3)).
As the grains flow down, they are exposed to the hot air generated by the burner and dried, but the grains located at the four corners are guided by the corner walls ■, reducing the flow resistance and drying the grains. Even when the moisture content is high, the grain has a lot of grains attached to the branches, or the grain has a lot of straw dust mixed in, the grains are kept in the four corners of the downstream chamber. There is no longer any stagnation, and therefore patchy dryness does not occur.

Embodiment In the illustrated example, (8) is a dryer, and the side wall is rectangular in plan view long in the front and back direction, and consists of front and rear side walls (5), 6) and left and right side walls 0, (6), and this side wall (!5) The operation box (9) and the moisture measuring device 0 are removably attached to the front side, and the upper part of the side wall has a ceiling plate l1l) and αυ. A lower helical transfer gutter (2) located in the center of this side wall (6) and having a U-shape when viewed from the front and extending in the front-rear direction is provided, and a grain collection room (0) which is V-shaped when viewed from the front is provided above this lower helical transfer gutter (2). A vertical drying chamber (2 and Slanted walls (3), (3) are provided that connect the upper part of the outer ventilation mesh plate and the side wall (6) to guide the grains down into the drying chamber (2), and the upper part of the inner ventilation mesh board A downstream chamber (4
), a storage chamber (1) is formed in the upper part of this downstream chamber, and a partition plate is provided at the lower part of the ventilation mesh plate. This flowing down chamber (1) and the side walls (5), 6) forming the storage chamber (1), the side wall 0.0, and the inclined walls (2), (3) are short-circuited to promote the flow of grains. Corner walls (7) are provided at the four corners. qO
is a ventilation chamber, and this ventilation chamber 00 is connected to the burner Q7+ installed on the front side of the side wall 6), and 0 is an exhaust chamber, and this ventilation chamber (to) is installed on the rear side of the side wall (!5). It is connected to exhaust fan 0.

An upper spiral transfer gutter O is provided along the ceiling plate Q1) at the upper part of the storage chamber (1), and the grains to be transferred are supplied to the center of the upper spiral transfer gutter (C) into the storage chamber (1). A supply port is opened, and a diffusion plate is provided below the supply port.

@ is removably attached to the front side of the side wall 6) of the grain raising machine, and the packet conveyor Q1 belt is stretched inside between the upper and lower pulleys, and between the upper end and the front end of the upper helical transfer gutter 0. A dispensing tube (c) is removably provided and communicated with it, and a supply gutter (c) is removably provided and communicated between the lower end and the front end of the lower helical transfer gutter.

The hot air generated from the burners installed on the front side of the side wall 6) is sucked into the exhaust fan installed on the rear side of the side wall 6), and the drying chamber (21) formed between the ventilation mesh plates is ventilated. The grains stored in the dryer (8) are dried while being exposed to this hot air while flowing down from the storage chamber (υ) through the downstream chamber (■) inside the drying chamber (■), and are fed out to the lower part by the feeding valve. The grains are transferred and discharged into the supply gutter (C) through the lower helical transfer gutter ■, transported to the upper part by the grain raising machine @, transferred to the supply port through the upper helical transfer gutter ■, and into the storage chamber (1) by the diffusion plate ■. When the grains are evenly diffused and reduced, circulated and dried, and reach a specified moisture content, the operation box (9) automatically controls the operation box (9) to automatically stop the dryer. The drainage chamber (4
) The four corners of the inclined wall (3) are closed by the corner wall (■), so grains do not stagnate and dry spots do not occur.

Note that the corner wall (7) may be formed of a multi-perforated plate.
