Abstract

PURPOSE:To guide grain into either of right and left dryer chambers, if thee is only a small amount of grain, for preventing blow-by of hot blast by providing a guide plate disposed in the opening at the upper portion of a grain riser and adapted for changing the direction of grain feed to a storing chamber. CONSTITUTION:Grain is fed from a grain riser 3 to a storing chamber 2, and while it flows down from the storing chamber 2 into right and left dryer chambers 1, the grain is dried by hot blast generated by a burner 17 and led into the dryer chambers 1. When there is only a small amount of grain to be accommodated in a dryer, a guide plate 5 provided in the opening 4 at the upper portion of the grain riser is directed toward either one of the dryer chambers 1 to which grain is to be introduced. Thus, the grain fed into the storing chamber 2 flows down, guided and supplied only into the one of the right and left dryer chambers 1, and the one of the dryer chambers 1 is fully filled with the grain, preventing blow-by of hot blast. Further more, as the grain is uniformly fed into the storing chamber 2 by the guide plate 5, there is no fear of reduction of drying speed or spotted drying.

Description

[Detailed description of the invention] Industrial applications The present invention relates to a grain feeding device for a grain dryer.

Problems to be Solved by the Invention The grains supplied from the upper opening of the grain raising machine to the storage chamber are caused to flow down from the storage chamber to the drying chambers on both left and right sides of the lower part.
This is a grain dryer that dries hot air generated by a burner through the drying chamber.When the amount of grain stored in the dryer is small, the drying chambers on both the left and right sides will not be filled with the grains supplied. In such a situation, the hot air may blow through many areas in the drying chamber where there are no grains, which may reduce the drying speed, or the grains to be supplied may not be evenly supplied into the storage chamber. This may cause patchy dryness.

Means for Solving the Problem This invention is a grain dryer in which a drying chamber (1) for drying grains with ventilation while flowing down is arranged on the left and right sides. The storage chamber (2) above the left and right drying chambers (1) is placed in the upper opening (4) of the grain hoist (3) which looks into the storage chamber (2) of the chamber (1). The grain feeding device of the grain dryer is provided with a guide plate (5) for changing the direction of grain feeding to the grain dryer.

Effects and Effects of the Invention The grains supplied from the f2 machine (3) into the storage chamber (2) are generated by the burner while flowing down from the storage chamber (2) to the drying chambers (1) on both the left and right sides. The hot air is passed through the drying chamber (1) and dried.
By directing the guide plate (5) provided in the section ) toward the drying chamber (1) that is to be supplied, the guide plate (5) guides only the drying chamber (1) on one of the left and right sides. The drying chamber (1) on one side is filled with grains and it is easy to prevent hot air from blowing through the drying chamber (1). , and the storage chamber (2)
Since the grains fed into the container are fed evenly by the operation of the guide plate (5), the drying speed does not decrease and drying does not occur unevenly.

Embodiment In the illustrated example, the a-wall of the dryer (6) has a rectangular shape in a 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 (8), (8). The upper part of this machine wall has ceiling plates (9), (9), the front center of this machine wall has a grain hoist (3), and the front wall plate (7) has an operation box. (1
0) is removably attached.

Part 4! ! A transfer gutter (11) located in the center of the wall and extending in the front-rear direction and having a single character shape when viewed from the front is provided, and a transfer helix (12) for feeding and transferring grains is pivotally supported in the transfer gutter (11), This transfer helix (12) is configured to feed transferred grains into the lower end of the grain hoist (3). A vertical downstream chamber (13) is provided at the top of the transfer gutter (12) for communication, and a V-shaped drying chamber (1) in front view is installed at the top of this downstream chamber (13).
(14) is an inclined plate extending above the lower ventilation mesh plate, and (15) is a mountain-shaped slope on the upper ventilation mesh plate. This inclined plate (15) and the upper ventilation mesh plate form a ventilation chamber (
1B) and provided on the front wall plate (7).
17) through the ventilation chamber path (IB), and the left and right wall plates (8), (8), the lower ventilation net plate and the lower partition plate (
19) to form an exhaust chamber (20).

It communicates with the exhaust air It (28) provided on the rear wall plate (7). A rotatable shaft (21) is pivotally supported between the front and rear wall plates (7) between the lower partition plate (18) and the outside of the bottom of the transfer gutter (11). ) on the opening/closing plate (22
) is fixed and grains are supplied only to one side of the drying chambers (1), (1), when this opening/closing plate (22) is placed in a hanging state, the grains of the drying chamber (1) are supplied. The structure is such that hot air does not pass through the drying chamber (1) on the side that is not in use. A storage chamber (2) is formed in the upper part of the drying chamber (1), (1), and an opening (23) is provided in the center of the upper part of the front wall plate (7) forming the storage chamber (2). ing.

Inside the grain raising machine (3), a heketoto conveyor (24) belt is stretched between the upper and lower pulleys, and an opening (4) is provided at the upper end. Rotatable guide plates (5) are provided at three locations in the section, and each guide plate (5) h
and a disc (27) provided at the end of the shaft of the motor (26) fixed to the ceiling plate (9) by a rod (25),
The guide plates (5) are configured to rotate left and right by the rotation of the motor (2B), and the opening (4) in the upper part of the grain raising 41J1 (3) and the opening (7) in the front wall plate (7) The grains conveyed by the packet conveyor (24) are communicated with the storage chamber (23) through the 6B openings (4) and (23).
2) It is a configuration that is supplied to the inside.

By operating the operation box (lO) provided on the front wall plate (7), the front wall plate (7)! The hot air generated from the burner (17) installed in the rear wall plate (7) is sucked by the exhaust fan (2B) installed in the rear wall plate (7), thereby drying chambers (1) on both the left and right sides formed between the ventilation mesh plates (1), ( 1) Ventilation and drying The grains stored in the drying chamber (8) are dried by this hot air while flowing down in the drying chambers (1), (1), and are transferred to the helical wire ( 12), the grain is fed out, and then transferred and discharged into the grain raising machine (3), which transports it to the upper part and opens the grain through the opening (4).
) is guided by a guide plate (5) that rotates from side to side, and the grains are evenly diffused and returned into the storage chamber (2) through the opening (23) of the front wall plate (7), and are circulated and dried. When the moisture content reaches the specified level, the operation box (10) automatically controls the drying process.
m (6) will automatically stop, but when the amount of grain stored in the dryer (6) is small, the rotation of the motor (2B) will be stopped and the grain in the drying chambers (1), (1) will be stopped automatically. The guide plate (5) is rotated and fixed to the side of this drying chamber (1) where grains are to be supplied, and at the same time, the shaft (21) is rotated to adjust the opening/closing plate (22) to a hanging state. With no ventilation to the drying chamber (1) on the side to which grains are not supplied, the grain raising chamber a (3) passes through the storage chamber (2) to the drying chamber (1) on the one side.
1) Supply only the side and dry.
