Description

DETAILED DESCRIPTION OF THE INVENTION Field of the Invention The present invention relates to a grain feeding and discharging device for a grain dryer.

Problems to be Solved by the Invention In order to discharge the grains that have been dried in the dryer, the drying room In the case where grains are conveyed to the upper part by a raising device and then discharged, this is inconvenient because the position of the outer shell device is fixed and the discharge positions are limited.

Means for Solving the Problem This invention provides a diffusion impeller (2) located above the tempering chamber (1) that receives supplied grains and spreads them to the outer periphery by rotation.
and a discharge pipe (3) located on the outer periphery of the diffusion impeller (2) to guide the grains diffused by the diffusion impeller (2) out of the tempering chamber (1). wing wheel case (4)
A grain supply and discharge device for a grain dryer, which is configured to be switchable so as to move the diffusion impeller (2) up and down relatively to expose the rotating outer periphery of the diffusion impeller (2) into the conditioning chamber (1). The structure is as follows.

Functions and Effects of the Invention During drying, the grains housed in the dryer are exposed to the tempering chamber (1) by moving the diffusion impeller (2) downward. The grains supplied onto the car (2) are evenly diffused and returned into the tempering chamber (1) by the diffusion wheel (2), and when drying is completed, the dried grains are discharged outside the machine. By moving the diffusion impeller (2) in the - direction, the diffusion impeller (2) is housed in the impeller case (4).
) The grains supplied above are discharged from the impeller case (4) by the dispersion impeller (2) to the outside of the machine via the discharge pipe (3),
In this way, by switching the vertical movement of the diffusion impeller (2), the grain can be easily switched between being diffused and returned into the tempering chamber (1) and being discharged to the outside of the machine. Since there is no resistance on the outer periphery of the diffusion impeller (2), the diffusion condition is good during diffusion and reduction into the tempering chamber (1). It has a simple structure that allows for diffusion reduction and discharge outside the machine.

Embodiment In the illustrated example, the wall of the dryer (5) has a rectangular shape in plan view that is long in the front and back direction, and consists of front and rear wall plates (6), (6) and left and right wall plates (7), (7). At the top of this machine wall is a ceiling plate (
8). A lower helical transfer gutter (9) located in the center of the machine wall in the left-right direction and extending longitudinally in the shape of an opening in front view is provided. A grain collection room 00 is formed, and this grain collection room θL+
Drying chambers 01) and 01) placed on top of the drying chambers 01) and 01) are formed between the left and right ventilation mesh plates and communicated with each other, and feed rolls 0 and 0 are provided at the bottom of these drying chambers 01) and 01). , each ventilation mesh board"1
An inclined plate is provided on the front side, and a partition plate is provided on the lower side, and a ventilation chamber (13) is formed between the inner ventilation net plates to communicate with the burner Oa provided on the front wall plate (6). The ventilation chamber θ0 formed between the board and the left and right wall panels (7) and (7) is communicated with the ventilation fan OQ provided in the rear wall panel (6).The drying chamber 01)・01) A tempering chamber (1) is formed on the upper side, and above the ceiling plate (8) above the tempering chamber (1),
An upper helical transfer gutter 0η is provided along this ceiling plate (8), and a supply port Qal for supplying grains to be transferred is opened at the terminal end of this "partial helical transfer gutter a"i).
The impeller case (4) and the discharge tube (3) are rotatably mounted integrally at a position communicating with the supply port 08) between the engine and the ceiling plate (8), and a pair of gears rotating diffusion axis o1
A groove ring is provided in the circumferential direction at the upper end, and a diffusion impeller (
2) is fixed, and the outer circumference of the diffusion impeller (2) and the inner circumference of the impeller case (4) are provided with a gap that does not allow grains to be trapped;
The diffusion axis o1 has a groove 0υ in the axial direction, and this groove (2])
K inserts the key (A) and opens the upper helical transfer gutter 07)
A shifter (to) which is shaped like a letter in side view is rotatably attached to the upper part, and the tip of this shifter (a) is inserted into the groove (e) of the diffusion shaft arm, and the other side The end of the wire (C) is attached to the tip of the curved part, and the other end is attached to a lever (C), which is rotatably attached to the grain raising device. By operating the lever (c), the shifter (c) moves 1", and the diffusion shaft 09 and the diffusion impeller (2) move up and down, causing the diffusion to flow into the tempering chamber (1). When the impeller (2) is exposed, the grains are diffused and returned into the tempering chamber (1), and when the impeller case (4) contains the diffusion impeller (2), the grains are diffused and returned to the tempering chamber (1). The grains are discharged from the impeller case (4) by the diffusion impeller (2) to the outside of the machine via the discharge pipe (3).

The grain raising device (c) is detachably attached to the front part of the front wall plate (6), has a bucket inside, a conveyor belt (a) and is stretched between the upper and lower pulleys of the belt truck, and has an upper end portion and the upper helical conveyor. Gutter (17
) A dispensing tube (c) is removably provided at the 1iiiI end for communication, and a supply gutter (a) is removably provided for communication between the lower end and the front end of the lower helical transfer gutter (9). I'm letting you do it.

An operation box (to) is removably attached to the front wall plate (6).

The hot air generated from the burner 0→ of the front wall plate (6) is sucked by the exhaust fan 0→ of the rear wall plate (6), thereby cross-ventilating the drying chamber 01) formed between the ventilation mesh plates. , dryer (5
) The grains stored in the drying chamber 01) are dried while being exposed to the hot air while flowing down the drying chamber 01), are delivered to the lower part by the delivery roll 0, and are raised in the lower helical transfer gutter (9). The grains are supplied into the device (c), transported to the upper part by the grain raising device (c), and are exposed inside the tempering chamber (by operating the lever (c) from the supply port α8) of the upper helical transfer gutter 071. The diffusion impeller (2) is supplied with the diffusion impeller (2).
Then, the water is evenly diffused and reduced into the conditioning chamber (1) for circulation drying, and when the specified moisture content is reached, it is automatically controlled and stopped by the operation box (to). To discharge the dried grains, operate the lever (c)! ll wing wheel case (4)
The diffusion impeller (2) is supplied to the dispersion impeller (2) in which the dispersion impeller (2) is built-in, and the discharging tube (3) is supplied from the impeller case (4) at the dispersion impeller (2). By operating the lever (c), the diffusion impeller (2) can be moved up and down and can be easily switched between the drying operation state and the discharge operation state.
