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 Grain fed to the upper storage chamber by the grain hoist is circulated downward from the storage chamber to the drying chamber by rotating the delivery valve at the bottom of the drying chamber, while the hot air generated by the burner is circulated. In the grain dryer, the grains are dried by ventilation into the drying chamber, and the moisture content of the grains flowing down in the storage chamber is detected by a moisture measuring device attached to the wall plate of the storage chamber. When the amount of grain stored in the container is relatively small to the vicinity of the moisture measuring device, as the grain dries, the capacity decreases and the position of the grain is below the moisture measuring device. If this happens, the moisture measurement device will detect the moisture content without any grains, and therefore the moisture measurement device will detect the end of drying, and the drying end signal will cause the moisture measurement device to detect the end of drying. Even when the dryer is stopped, the grain may still be undried.

Means for Solving the Problem This invention provides a delivery valve (
2), the upper storage chamber (4) is moved by the grain raising machine (3).
The supplied grains are transferred from this storage chamber (4) to the drying chamber (1).
), and was dried by hot air sucked and discharged from the burner (5) through the drying chamber (1) to the exhaust fan (6), and attached to the wall plate (7) of the storage chamber (4). In a dryer configured to use a moisture measuring device (8) to detect moisture in grains flowing down in this storage chamber (4), a portion below the wall plate (7) on the side where the moisture measuring device (8) is located. The outer diameter of the one end of the delivery valve (2) has a smaller diameter (9
) The structure of the grain feeding device of the grain dryer is as follows.

Functions and Effects of the Invention The grains supplied and stored in the upper storage chamber (4) by the grain hoist (3) are transferred from the storage chamber (4) to the drying chamber (1) by rotating the delivery valve (2). ), and the burner (5
) is sucked and exhausted by an exhaust fan (6), passes through the drying chamber (1) on the way, and is dried, and is dried in the storage chamber (4).
This storage chamber (4) is measured by the moisture measuring device (8) on the wall plate (7).
Moisture in the grains being dried by flowing down inside the storage chamber (4) is detected, but even when the amount of grains stored in the storage chamber (4) is small, the wall on the side where the moisture measuring device (8) is installed is detected. The outer diameter part of the delivery valve (2) below the plate (7) has a smaller diameter (9) than the other outer diameter parts.
), the amount of grain fed out at the small diameter portion (9) of this feeding valve (2) is smaller than the amount fed out from other parts, and the state of grain accumulation in the storage chamber (4) is The moisture measuring device (
8) The upper part is deposited more than the other parts, and this moisture measuring device (8) constantly detects the moisture content of the grains flowing down in the storage chamber (4) to ensure accurate moisture detection. I can do it.

Embodiment In the illustrated example, the wall of the dryer (10) has a rectangular shape in plan view that is long in the front and back direction, and includes wall plates (7), (7) on the front and rear sides, and wall plates (11), (11) on the left and right sides. ), and has a ceiling plate (12), (I2) on the upper part of this machine wall,
A moisture measuring device (8) and an operation box (13) are detachably attached to the front wall plate (7).

A lower helical transfer gutter (14) which is located in the center of the machine wall in the left-right direction and extends in the longitudinal direction is provided, and a lower helical transfer gutter (14) having a mouth shape when viewed from the front is provided. A grain collecting room (15) is formed in the grain collecting room (15), and a vertical drying room ('l) (1) is formed between the left and right ventilation mesh plates and communicated with this grain collecting room (15) J2. (1), (1) The delivery valves (2), (2) are provided in the - door section, and the delivery valves (2) -.
That is, the wall plate (7) on the side where the moisture measuring device (8) is installed.
) side end outer diameter section is made smaller in diameter (9) than the other outer diameter sections to reduce the amount of grains that are fed out downward. An inclined plate is provided above each ventilation mesh plate, a partition plate is provided below, a ventilation chamber (16) is formed between the inner ventilation mesh plates, and a burner (5) is installed in the front wall plate (7). The left and right wall plates (11
), (11) and the left and right outer ventilation mesh plates, there is a ventilation chamber (1
7) and an exhaust fan (6) provided on the rear wall plate (7).
). A storage chamber (4) is formed above the drying chambers (1), (1), and the moisture measurement device is installed in an opening provided in the front wall plate (7) forming the storage chamber (4). The moisture measuring part of the device (8) is mounted in a protruding state, and the moisture measuring part M(8) detects the moisture of the grain flowing down in the storage chamber (4). An upper helical transfer gutter (18) is provided along the ceiling plates (12), (12) above the storage chamber (4), and the grains are transferred to the center of the upper helical transfer gutter (18). (4) A supply port for supplying the inside is opened, and a diffusion @ (19) is provided below this supply port.

The grain raising fi (3) is removably attached to the front part of the truss wall,
A bucket conveyor (20) belt is stretched between the upper and lower pulleys inside, and a dispensing cylinder (21) is removably provided between the upper end and the starting end of the upper helical transfer gutter (18) for communication. A supply gutter (22) is provided between the lower helical transfer gutter (14) and the terminal end thereof for communication.

The hot air generated from the burner (5) installed at the front of the machine wall is sucked in by the exhaust fan (6) installed at the rear, and the air is circulated across the drying chamber (1) formed between the ventilation mesh plates, and the dryer (lO
) The grains housed in the drying chamber (1) are dried while being exposed to the hot air while flowing down the drying chamber (1), and then the grains are dried in the drying chamber (1).
) to the lower part, the lower helical transfer gutter (14) discharges and supplies the grain into the supply gutter (22), the grain hoist (3) transports it to the upper part, and the upper helical transfer gutter (18) transfers it to the spreading plate ( 18)
The grains are transferred to the upper part and are evenly diffused and returned into the storage chamber (4) by the diffusion plate (19), and then circulated and dried. The device (8) detects moisture, and when the specified moisture is reached, the operation box (13)
The dryer (10) is automatically stopped by automatic control,
Even when the amount of grains stored in this dryer a (10) is small, the wall plate (7) on the side where the moisture measuring device (8) is attached
Since the outer diameter portion of the lower end of the feeding valve (2) is smaller in diameter (9) than the other outer diameter portions, the amount of grain fed out at this small diameter portion (9) is smaller than that at the other portions. Therefore, the upper force on the small diameter part (9), that is, the amount of grains deposited on the upper part of the moisture measuring device (8) is larger than that in other parts. ) does not detect moisture in a state where the grains are not flowing down, so the moisture is detected accurately and there is no chance of the grains being undried.
