Description

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

Conventional technology Conventionally, a valve motor rotationally drives a feeding valve that feeds out and flows down the grains, an exhaust fan motor rotationally drives an exhaust fan that sucks and exhausts hot air, an up and down transfer spiral that transports and conveys the grains, and a A motor for the shell raising machine that rotates the grain raising machine, a motor for the discharge valve that opens and closes the discharge valve that supplies grain to the discharge device, and a motor for the discharge device that rotates and drives the discharge device that discharges the grains to the outside of the machine. In addition, a tensioning work starting device, a drying work starting device, a discharging work starting device, a stopping device, etc. are provided to start and stop each of these motors for each grain drying operation, and each of these work starting devices is operated. Then, the dryer starts each work, and performs the tensioning work, drying work, and discharge work, and when the drying work and discharge work are completed, the respective motors are automatically stopped in sequence at appropriate time intervals to stop the dryer. Also, when the stop device is operated when the tensioning work is completed, all the motors are stopped at the same time and the dryer is stopped.If you want to stop the dryer during the drying work or the discharge work, you need to operate the stop device. When operated, the motors were configured to stop all at once, thereby stopping the dryer.

Problems to be Solved by the Invention When performing a discharge operation to discharge dried grains to the outside of the machine, each motor rotates and the dryer is started by operating the discharge operation starting device, and the dryer is started and the dryer is discharged inside the storage chamber. The dried grains are
From this storage chamber, the grain is fed to the lower part by a feeding valve in the drying chamber, flows down and is supplied into the grain collection gutter, is transferred by the lower transfer spiral in this collection gutter and is supplied into the grain hoisting machine, and is fed into the grain hoisting machine. It is transported to the upper part and supplied into the transfer gutter, and depending on the open state of the discharge valve in the discharge funnel provided at the bottom of the starting end of this transfer gutter,
The grains are supplied through this discharge funnel into the discharge device, which discharges them outside the machine, and when there are no dried grains in the dryer, a circulation sensor detects the circulation state of the grains. When it is no longer detected, each motor is automatically stopped in the order of the feeding valve motor, the grain hoist motor, the exhaust fan motor, the discharge device motor, and the exhaust fan motor at appropriate time intervals. The dryer stops, but
In this dryer, when a stop device is operated during this discharge operation, the motors automatically stop all at once and the dryer is stopped. In order to change the discharge direction of the discharge device to discharge to the adjacent storage, operate the stop device to temporarily stop the dryer, change the discharge direction, and perform the discharge operation again. Even if the starting device is operated, once the motors have stopped, the ejecting device may be clogged with grains being ejected, and this clogging may cause restarting. There were times when I couldn't do it.

Means for Solving the Problems The present invention provides for drying grains in a dryer (21) that dries the grains with hot air while circulating the grains.
) A sequential stop control type 21 (48) that automatically stops each dryer unit of this dryer (21) sequentially at appropriate time intervals upon completion of discharging outside the machine;
The operation control device is configured to be manually operable during the operation of discharging the dried grains to the outside of the machine.

Effect of the Invention When discharging dried grains to the outside of the machine, for example, when the discharging operation starts? When you manually operate TFI, the dryer (
21) rotates, and the dried grains in the storage chambers of each drying function section of this dryer (21) are fed from this storage chamber into the drying chamber to the lower part by a feeding valve and supplied into the grain collection chamber. The grain is transferred by the lower transfer spiral in the room and supplied into the hoisting machine, and by this hoisting machine it is conveyed to the upper part and supplied into the transfer gutter. The grains are supplied through the discharge funnel into the discharge device, and are discharged outside the machine by this discharge device.When there are no grains within the drying 4m (21) and the grains no longer circulate in the dryer (21), the circulation begins. When the sensor no longer detects circulating grains, each drying function section of the dryer (21) automatically stops one after another at appropriate time intervals using the stop control type 21 (47), and this dryer (21) automatically stops.

When it is desired to stop the dryer (21) during this drying operation, by manually operating the discharge operation starting device again, each drying function section of this dryer (21) is activated when the grain discharge is completed. Similarly, the stop control type 21 (47) automatically stops the dryer (21) at appropriate time intervals.
