Description

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

Problems to be Solved by the Invention In a dryer that repeatedly circulates and dries grains while flowing them down from a storage chamber through a downstream chamber to a drying chamber, the grains flowing down in the drying chamber are generated by a burner. Hot air passes through this drying chamber and is exposed to this hot air to dry it. However, when the grains to be housed and dried in the dryer are wheat grains and have a particularly high moisture content, the side walls forming the storage chamber The flow of grains on the inclined plate portion forming the flow chamber may be poor and the grains may stagnate, resulting in dry spots.

Means for Solving the Problem This invention has an inclined plate (2) which is connected to the bottom of a storage chamber (1) for storing grains and which slopes from both the left and right sides to the inner lower part, so that the lower end is fixed to either the left or right side. Ventilated drying room tilted downward to the side (
In the downstream chamber (4) connected to the drying chamber (3), there is provided a downstream guide plate (5) that is inclined at an appropriate angle along the side of the inclined plate (2) on the side opposite to the inclination of the drying chamber (3). The structure of the grain dryer is as follows.

Effects of the invention The grains accommodated in the storage chamber (1)
While flowing down the drying chamber (3) through the downstream chamber (4) formed by the inclined plate (2), it is exposed to hot air generated by a burner and dried. The grains that are located on the plate (2) and flow down can be dried by providing a flow guide plate (5) on the side of the outer inclined plate (2), so that the grains to be dried are barley grains with high moisture content. Even in some cases, the outer inclined plate (2) in the flow chamber (4) is closer to the flow guide plate (5) than the inner inclined plate (2). Since the partitioned area is narrow, the suppression of the grains by the outer inclined plate (2) is reduced, and therefore the flow resistance of the grains is reduced, and the grains are pushed into the outer inclined plate (2). There will be no stagnation, and therefore no patchy dryness will occur.

Embodiment In the illustrated example, the dryer (6) has a rectangular shape in plan view that is long in the front-rear direction and consists of front and rear wall plates (7), (7) and left and right wall plates 1), (8). Ceiling board (
9), (9), and an operation box (10) is detachably attached to the front wall plate (7).

A transfer gutter (1!) located in the center of the machine wall and extending in the front-rear direction and having a U-shape when viewed from the front is provided, and this transfer machine (11)
A helix (12) for feeding and transporting grains is pivotally supported inside. A passage window (13) vertically viewed from the front is formed on the transfer gutter (11) and communicated with the passage chamber (13).
Above, drying chambers (3), (3) having a V-shape when viewed from the front are formed with a constant width in the upper and lower sides between the upper and lower ventilation mesh plates (14), and communicate with each other. An inclined plate (2) is provided above the extension, a mountain-shaped inclined plate (2) is provided on the upper ventilation mesh plate (14), and a flow chamber (2) is provided between the inclined plates (2), (2). 4), (4) is formed, and the lower ventilation net plate (10) is formed along this inclined plate (2) at a position closer to the inclined plate (2) side on the extension of this flow chamber (4). A downstream guide plate (5) is provided which is inclined at an appropriate angle.A mirror mountain-shaped inclined plate (
2) and the upper ventilation mesh plate (10) form a ventilation chamber (15), which communicates with the burner (tS) provided on the front wall plate (7), and the left and right wall plates (8), A ventilation chamber (18) is formed by the lower ventilation mesh plate (10), the inclined plate (2), and the lower partition plate (17), and the ventilation fan (19) provided on the rear wall plate (7). A storage chamber (1) is formed above the downstream chambers (4), and the ceiling plate (9) above the storage chamber (1)
), an upper helical transfer gutter (20) is provided along (9),
A supply port for supplying transferred grains into the storage chamber (1) is opened in the center of the upper helical transfer gutter (20), and a diffusion plate (21) is provided below the supply port.

The grain raising machine (22) is detachably attached to the front part of the front wall plate (7), and a bucket conveyor (23) belt is stretched between the upper and lower pulleys inside, and the upper end and the upper helical transfer gutter are connected to each other. (
20) A configuration in which a dispensing tube (24) is removably provided between the starting end and the transfer gutter (11) for communication, and a supply gutter (25) is provided and communicated between the lower end and the terminal end of the transfer gutter (11). It is.

In addition, the left and right wall plates (8), (8) are in a divided configuration, and the divided left and right wall plates (8), (8) and the inclined plate (2),
(2) may be integrally formed so that they can be taken out outwardly, and the downstream guide plate (5) and the outer inclined plate (2) may be configured so that they can be taken out outwardly.
), and the inner inclined plate (2).This king may be connected by providing partition plates at appropriate intervals in the front-rear direction.

By operating the operation box (1o) provided on the front wall plate (7), hot air generated from the burner (18) provided on the front wall plate (7) is directed to the exhaust provided on the rear wall plate (7). The drying chambers (3), (3) formed between the ventilation mesh plates (10, (14)) are ventilated by suction by the wind machine (19), and the grains stored in the dryer (6) are transferred to the storage chamber. (1) to flow chamber (4), (4
), the drying chamber (3), is exposed to this hot air while flowing down inside (3), is dried, passes through the passage chamber (13), and is dried by the spiral (12).
), is transferred and discharged into the supply gutter (25) while being fed out by the transfer gutter (11), transported to the upper part by the grain hoist (22), and spread from the supply port by the upper helical transfer gutter (2G) 11 (21)
Transferred to the top and spread this! (21), the grains are evenly diffused and reduced into the storage chamber (1), and when the grains reach the specified moisture content through circulation drying, the operation box (10) automatically controls the dryer (6). Although it automatically stops, the dryer (6
) Even when the grains to be stored in the storage chamber (1) are barley and have a particularly high moisture content, the left and right wall plates (8), (8) forming the storage chamber (1)
) Since the downstream guide plate (5) is provided near the inclined plate (2) part connected to the inclined plate (2), the area on this inclined plate (2) side is narrow, so grains hanging on this inclined plate (2) are suppressed. Since this decreases, the flow resistance of grains located on this inclined plate (?) portion and flowing down is lower than that of the left and right wall plates (8) and (8) portions, and the grains can flow down smoothly.
