Description

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

Problems to be Solved by the Invention ``While grains are diffused and supplied from the upper part of the storage chamber and flowed down from this storage chamber to the drying chamber with multiple rows at the lower part, hot air generated by a burner is passed through the drying chamber. When the amount of grain stored in the dryer is small,
The drying chamber of the plurality of rows may not be completely filled with grains, and in such a state, the drying speed may decrease because the hot air blows through many parts of the drying chamber where there are no grains.

Means for Solving the Problem This invention provides a multi-row drying chamber (1) in which grains are ventilated and dried while flowing down;
The storage chamber (2), which is made of an elastic material or cloth material, receives the grains that are diffused and supplied from the upper part, and the plurality of drying chambers (1)
The grain dryer has a structure of 114, which is provided with a guide plate (3) that can be tilted to guide the flow down to a part of the drying chamber (1).

Effects and Effects of the Invention The grains diffused and supplied into the storage chamber (2) are
The hot air generated by the burner is passed through the drying chamber (1) and dried while flowing from the drying chamber (1) to the multiple rows of drying chamber (1). Even if there is a guide plate (3) made of an elastic body or cloth material provided in the storage chamber (2), by fully operating the guide plate (3).
) is inclined and the grains supplied into the storage chamber (2) are guided down and supplied only to some of the drying chambers (1) among the plurality of drying chambers (1). (1) i-1:
Since the amount of grain is a and hot air does not blow through, and the guide plate (3) is made of an elastic material or cloth material, the storage chamber (2
) It also prevents damage to the grains fed into the interior and prevents noise.

Embodiment In the illustrated example, the wall of the dryer (4) is rectangular in plan view, long in the front and rear direction, and the front and rear wall plates (5), (5) and the left and right wall plates (6), (6) are similar to each other. The ceiling plate (which is part of the machine wall)
7) and (7), and an operation box (8) is detachably attached to the front wall plate (5).

A lower helical transfer gutter (9) is provided in the center of the left and right inside the machine wall and has a cross-shaped shape when viewed from the front and extends in the front-rear direction. A vertical drying chamber (1
) and (1) are formed between the left and right ventilation mesh plates to communicate with each other, and in the lower part of this drying chamber (1) and (1), there is a dispensing pulp (1υ
1υ is set. A mountain-shaped inclined plate α4 is provided above the inner ventilation mesh plate, nuts are fixed at appropriate intervals on the inside of the upper part of this inclined plate (2), and a partition plate is provided in the lower part of the inner ventilation mesh plate. A ventilation chamber a3 is formed by the inner ventilation net plate, the inclined plate Q2, and the partition plate, and communicates with the burner 0 provided on the front wall plate (5), and the inclined plate 0 is provided above the outer ventilation net plate.
F9Th is provided, a partition plate is provided below, and these outer ventilation net plates, conflict swash plate αG, the left and right wall plates (6), (6), and the partition plate form ventilation chambers α→・αQ, This ventilation room α uniform
A box-shaped exhaust duct chamber Q8) communicating with Qf9 is connected to the rear wall plate (
5), an exhaust fan 07) is fixed to the exhaust passage chamber α, and the exhaust fan αη and the exhaust chambers 00 and αe are communicated with each other. There is a storage chamber (2) above the drying chamber (1).
) completely formed, and the ceiling plate (7) on the upper part of this storage chamber (2).
An upper helical transfer gutter is provided along (7), and this upper helical transfer gutter transfers grains to the central part of this storage chamber (2).
) is opened, and a diffusion plate (4) is provided below the supply port. A guide plate (3) made of an elastic material or a cloth material is fixed to the inside of the upper part of the left and right wall plates (6) (6), which form the entire storage chamber (2), in a hanging state with bolts and nuts, etc., to prevent the diffusion. When all the grains to be supplied into the storage chamber (2) are supplied to only one side of the drying chamber (1) using a board, the grains are fixed to the inclined plate (6) with a bolt or the like. A shaft Qυ is rotatably supported between the upper and lower wall plates of the exhaust duct chamber α,
A valve (a) is fixed to this axis Qσ, and a lever @ is fixed to the upper end of the shaft t2), and this lever @ is configured to be fixed to the earth wall board part of the exhaust duct room Q8). By rotating the lever @, the terminal end port of the exhaust chamber 0Q is closed by the valve □□□.

The grain raising machine ■ is removably attached to the front part of the front wall plate (5),
A bucket (7) conveyor (c) V) is stretched between the upper and lower pulleys, and a dispensing tube (c) is removably provided between the upper end and the starting end of the upper helical transfer gutter 01. A supply gutter is provided between the lower end and the terminal end of the lower helical transfer gutter (9) for communication.

In addition, when preventing the hot air from passing through the drying chamber (1) on the side where grains are not supplied, a box-shaped closing plate with the same width as this drying chamber (1) is installed on the rear wall plate (5). The drying chamber (1) on the side to which grains are not supplied is closed when the closing plate is folded down and inserted into the drying chamber (1). Alternatively, the left and right wall plates (6-inch) can be divided into upper and lower parts, and the upper end of the upper side can be rotated. One of the left and right wall plates (6) on the upper side of the drying chamber (6) is tilted inward, and the grains are guided down only to the inner drying chamber (1) by this inclined wall plate (6). J7&
You may also choose to do so.

The hot air generated from the burner α installed on the front wall plate (5) is sucked by the exhaust fan α installed on the frame of the exhaust duct room α, and is then passed through the drying room (4-inch dryer). The grains stored in the drying chamber (1) are dried by this hot air while flowing down inside the drying chamber (1), are fed out to the lower part by the feeding valve Qυ, and are sent into the supply gutter (a) by the lower helical transfer gutter (9). The grains are transferred and discharged, transported to the upper part by the grain raising machine (c), fed onto the diffusion plate (e) by the upper helical transfer gutter (1 gutter), and fed to the storage chamber (2) by the diffusion plate (a).
), and when the grain reaches the specified moisture content through circulation drying, the operation box (8) automatically controls the dryer (4) to automatically stop. When the amount of grains to be stored in the storage chamber (2) is small, the guide plate (3) is tilted around 1, the lower edge is fixed to the inclined plate α, and the diffusion plate is used to diffuse and supply the grain into the storage chamber (2). The grains to be dried are guided down by this guide plate (3) only into the drying chamber (1) on one side, and the grains are fed to the drying chamber (1) using the ear stopper 1. The end port of the exhaust chamber OQ on the side where the grains are not stored is closed with a valve (a), and the hot air generated in the burner a is vented only to the side of the drying chamber (1) where the grains are stored. and dry.
