Description

[Detailed Description of the Invention] [Industrial Application Field] The present invention provides grains that are accurately fed into a horizontally long drying cabinet with an open top surface by reciprocating movement of a conveyor cart, and drying in a stationary state. A large amount of grain supplied to the source can be uniformly dried while being transferred to the discharge side in an even state by the stirring, mixing and transferring action and the suction and ventilation action of hot air obtained by solar heat. Installed in the grain leveling device in the agitation draft dryer.

[Prior Art] Conventionally, a drying chamber is divided into an upper part and a ventilation chamber at a lower part, with a horizontal ventilation panel disposed inside a horizontally long drying cabinet with an open top surface, and a drying chamber is provided on the drying cabinet. A stirring and mixing transfer machine is installed to move the grain supplied to the storage area toward the discharge section so that it can freely move back and forth along the longitudinal direction, and the grain stored in a stationary state is efficiently stirred and mixed and transferred by the action of stirring and the transfer action of hot air and the action of pumping hot air. A grain drying device that discharges grains from a discharge section while drying them well and uniformly is well known and was described in, for example, Jikkanno 2-13992 before the present application.

[Problems to be Solved by the Invention] By the way, in conventional grain drying devices of this type, when feeding grain into the drying case, the grain is directly fed to the input side of the drying case through a supply cylinder of an appropriate diameter, and the grain is deposited in a fixed quantity. At this stage, the stirring and mixing transfer machine was run back and forth several times to feed the grain.

Therefore, because the conventional grain feeding operation depended on the conveying capacity of the stirring and mixing transfer machine, it was difficult to efficiently achieve the speedy grain feeding operation, and the grain was fed into the drying cabinet in an even state. Not only does it have to move the supply tube in a direction perpendicular to the longitudinal direction of the drying cabinet, but it also has to stop the grain loading operation when the stirring and mixing transfer machine moves backwards into the grain loading section. He had 3 points during his performance.

The present invention has been made in view of the problems of the conventional technology, and its purpose is to automatically stop the reciprocating movement and open/close the shutter along the longitudinal direction of the drying cabinet. By using a transport vehicle that can
Grain leveling in an agitating ventilation dryer that aims to increase the efficiency of grain leveling by quickly and continuously loading a large amount of grain to any position without relying on the conveyance of an agitating mixer. It is intended to provide a flat feeding device.

[Means for Solving the Problems] In order to achieve the above object, the grain leveling device in the agitating ventilation dryer according to the present invention has a horizontally long drying cabinet with a deserted top surface, and a horizontal ventilation panel as a boundary between the grain leveling device and the grain leveling device of the present invention. A drying chamber is divided into a suction chamber at the bottom, and a transport cart and an agitation/mixing transfer machine that can reciprocate along the longitudinal direction are mounted on the drying case, and a transport cart is mounted on the input side of the drying case. A flow control tank is installed to supply grain to the tank.

Then, when the transport vehicle comes into contact with the grains that had been put into the drying chamber, the transport vehicle is stopped, and at the same time, a shutter provided at the bottom of the transport vehicle is opened to allow the grains to be thrown into the drying chamber for an appropriate period of time. A detection body is installed that closes the shutter after the passage of time and causes the carriage to move backward toward the flow control tank.

In addition, if a level switch is installed inside the flow control tank that closes the shutter located at the bottom of the flow control tank and moves the transport vehicle forward at the same time as grain supply to the transport vehicle is completed.
It is possible to easily and reliably accomplish the automatic feeding of grain from the flow control tank to the transport vehicle and the automatic movement of the transport vehicle.

In addition, on the input side of the drying cabinet, the carriage is stopped when it comes into contact with the carriage that has been moved backwards to the bottom of the flow control tank, and a shutter installed at the bottom of the flow control tank is opened to close the flow control tank. If a home switch is provided to supply the grains inside to the transport vehicle, complete automation of the large-volume grain supply operation can be easily achieved.

[Function] Now, a flow control tank with an open shutter on the input side of the drying cabinet and a transport vehicle with a closed shutter are installed below it. Therefore, if the grains are placed in the flow control tank, the grains are successively supplied into the transport vehicle through the flow control tank.

When the transport vehicle is fully supplied with grain and the excess grain is deposited in the flow control tank, the level switch is released due to the grain pressure, and the shutter of the flow control tank is automatically closed. At the same time, the home switch is switched off. is turned on, and the conveyance cart is automatically advanced toward the discharge side.

As the transport vehicle moves forward, when the detection body installed on the transport vehicle comes into contact with the grain that had been previously placed in the drying cabinet, the forward movement of the transport vehicle is automatically stopped by the activation of the detection body. At the same time, the shutter is opened and the stored grain is thrown into the drying chamber. Then, several minutes later, the shutter automatically closes due to the activation of the timer, and at the same time, the transport vehicle is moved backward toward the input side of the drying cabinet.

As mentioned above, the transport vehicle is located on the input side of the drying box, that is, f
When it is moved backwards to the bottom of the f1F tank, the home switch is turned OFF by the contact operation with the transport vehicle, and at the same time, the reverse movement of the transport vehicle is stopped, and at the same time, the shutter of the flow control tank is closed, and when the supply starts, Similarly, the grains are successively supplied into the transport vehicle through the flow control tank.

Therefore, when a large amount of grain is loaded into the drying chamber by repeating the above-mentioned operation, the stirring mixer is made to run back and forth along the length of the drying cabinet, and at the same time, the previously loaded grain is leveled. While being stirred and mixed while being transferred from the input side to the discharge side, it is dried to a predetermined moisture content using hot air obtained from solar heat that is suctioned and distributed through a drying chamber toward a suction chamber, and finally discharged from the discharge section. Dry! ! Let them do the work.
