Description

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

Problem to be Solved by the Invention While the grains are flowing down from the storage chamber in the upper part to the drying chamber with multiple rows in the lower part, the hot air generated by the burner is passed from the hot air chamber to the drying chamber and the exhaust chamber to the exhaust fan. In a dryer that sucks and exhausts air and exposes the grains flowing down the drying chamber to this hot air to dry them, when the amount of grains stored in the dryer is, for example, small, the multi-row drying chamber is Sometimes the grain is not full, and in such a case, if the grain is stored and dried only in one side of the drying chamber, the amount of hot air will be reduced if the hot air is ventilated only to the side of the drying chamber where the grain is stored. As a result, the drying speed becomes too fast and a large number of grains and crushed grains are generated.Also, it is necessary to blow hot air into both the drying chamber where grains are stored and the drying chamber where grains are not stored. If this is done, a large amount of hot air will be blown only into the drying chamber on the side where grains are not stored, which may reduce the drying speed, so this is an attempt to solve both of these problems.

Means for Solving the Problems This invention utilizes hot air generated from an eight-cell (3) while flowing grains from an upper storage chamber (1) to a lower multiple-row drying chamber (2). chamber (4), the plurality of drying chambers (2) where the grains can flow down, and the exhaust chamber (5) and then the exhaust fan (6).
This ventilation chamber (5) is suctioned and exhausted to dry.
) part, there is a partition plate (8
) is the structure of the grain dryer.

Functions and Effects of the Invention The grains stored in the storage chamber (1) flow down from the storage chamber (1) into the drying chamber (2) with multiple rows at the bottom, while being exposed to the hot air generated from the burner (3). The grains are dried by suction and exhaust air from the hot air chamber (4) through the drying chamber (2) and the exhaust chamber (5) with the exhaust fan (6), but when the amount of grain stored in the dryer is small. Even when storing and drying grains only in the drying chamber (2) on one side, the terminal opening (7) of the ventilation chamber (5)
) is provided with a partition plate (8) that is in a half-open state, so that the hot air generated from the burner (3) is also ventilated to the drying chamber (2) on the side that does not contain grains. Since the amount of hot air flowing into the drying chamber (2) on the side where the grains are stored is reduced, a predetermined drying speed is maintained, and no shell side or crushed grains occur.

A yonokusu (3) is provided and communicated with each other, a ventilation chamber (5) is formed between the outer ventilation net plate and the left and right wall plates (11), and the rear wall plate The (io) section has a box-shaped exhaust duct chamber (
17) is provided, and this exhaust duct room (17) is provided with a t-side exhaust mode (6).
), and the exhaust fan (6) and the exhaust chamber (5) are communicated via the exhaust channel chamber (17). A rotatable shaft (18) is supported between the upper and lower wall plates of the exhaust duct chamber (17), a partition plate (8) is fixed to this shaft (18), and a partition plate (8) is fixed to this shaft (18). ) A lever (19) is provided at the upper end, and this lever (18) is configured to be fixed to the earthen wall board of the exhaust duct room (17), and by operating the lever (19), the partition plate (
8) is rotated so that the terminal opening (7) of the exhaust chamber (5) is in a half-open state. A storage chamber (1) is formed above the drying chambers (2), (2), and an upper helical transfer gutter (20) is installed along the ceiling plates (12), (12) above the storage chamber (1).
A supply port for supplying the transferred grains into the storage chamber (1) is opened in the center of the upper helical transfer gutter (20).

A diffusion adjustment plate (21) is provided at the bottom of this supply port so as to be rotatable left and right, and a diffusion plate (22) is provided at the bottom of this diffusion adjustment plate (21).
), and this diffusion plate (22) distributes the grains into the storage chamber (1).
), and the diffusion control plate (
By the operation 21), grains are diffused and supplied only to one of the drying chambers (2), (2).

The grain raising machine (23) is detachably attached to the front part of the front wall board (10), has a packet conveyor (20 belts) stretched between the upper and lower pulleys, and connects the upper end to the upper helical transfer gutter (20).
0) A dispensing pipe (25) is removably provided between the starting end and the dispensing pipe (25) for communication, and a supply gutter (2B) is provided between the lower end and the terminal end of the lower spiral transfer gutter (14). It communicates.

In addition, an extension sink gutter is provided at the bottom of the diffusion control plate (21), and an extension shaft is provided on the shaft to which the diffusion plate (22) is fixed.
This diffusion plate (22) may be configured to be positioned below the storage chamber (1) for diffusion and reduction, and another partition plate may be provided at the terminal opening (7) of the exhaust chamber (5). The terminal opening (7) may be configured to be fully closed, and the exhaust chamber (5) may be configured to be completely closed.

The hot air generated by the burner (3) provided on the front wall plate (10) is sucked by the exhaust air 111c6) provided in the air exhaust duct chamber (17) on the rear wall plate (10), thereby creating a hot air chamber ( 4) Air is sucked and exhausted from the drying chamber (2) and the exhaust chamber (5), and the grains stored in the dryer (9) are exposed to this hot air while flowing down inside the drying chamber (2). It is dried, and the delivery valve (1B
), the lower helical transfer gutter (14) transfers and discharges the grain into the supply gutter (26), the grain hoist (23) transports it to the upper part, and the upper helical transfer gutter (20) sends it to the diffusion control plate. (21) and is transferred and supplied onto the diffusion ff1 (22),
This diffusion plate (22) uniformly diffuses and returns into the storage chamber (1).

When the grains are circulated and dried and reach the specified moisture content, the dryer (9) is automatically stopped by the operation box (13), but the amount of grains stored in the dryer (9) is small. At this time, the diffusion control plate (21) is operated so that the grains are diffused and returned only to one side of the drying chamber (2), and at the same time, the supply of grains to the drying chamber (2) is controlled. Operate the lever (18) provided in the ventilation duct chamber (17) on the side that is not open and use the partition plate (8) to close the terminal opening (7) of the ventilation chamber (5) on this partition plate (8). By drying in a half-open state,
Since hot air is also ventilated to the side of the drying room (2) to which grains are not supplied, the drying room (2)
Since the amount of hot air passing through this drying chamber (2) on the side to which the grains are supplied is reduced, the grains are supplied only to the − blade side of the drying chamber (2) for drying. can always be dried at a predetermined drying rate.
