Description

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

Problems to be Solved by the Invention In a dryer that receives grains conveyed by a grain hoist using a helical transfer gutter and switches between supplying them into a storage chamber and discharging them outside the machine, it is difficult to supply grains into the storage chamber and discharge them outside the machine. If you forget to switch between external discharge and external discharge, for example, if the dryer is in the external discharge state during drying, when you start the dryer, the grains stored in the dryer will be discharged outside the machine. As a result, this dryer cannot be started.

Means for Solving the Problems This invention provides a helical (1) transfer gutter (1) for transferring and supplying grains.
2) is provided in the upper part of the grain storage chamber (3), and the supply port at the upper end is communicated with the upper part of the helical (1) transfer gutter (2) that protrudes outside the storage chamber (3). A grain raising machine (4) is provided to transport and supply grains, and the grains are discharged to the outside of the machine and stored at the bottom of the transfer gutter (2) between the grain raising machine (4) and the storage chamber (3). A discharge funnel (6) equipped with a built-in switching valve (5) that switches between supply and transfer into the chamber (3) is installed, and a detection sensor (7) that detects the opening and closing of this switching valve (5) is connected to the discharge funnel. Funnel (6)
A starting control device for a grain dryer is constructed by interlocking the detection of this detection sensor (7) with a start switch (8) that starts the dryer.

Function and effect of the invention The drying operation is carried out by closing the switching valve (5) of the discharge funnel (6), and moving the grains from the grain hoist (4) to the helical (1) and the transfer gutter (2).
) into the storage chamber (3), and this storage chamber (3)
Dry the inside under running water. In the discharge operation, the switching valve (5) of the discharge funnel (6) is opened, and the dried grains are transferred from the grain raising machine (4) to the discharge funnel (6) at the bottom of the transfer gutter (2). A sensor (7) is installed to detect the open/closed state of the switching valve (5) during the drying work, tensioning work, and discharge work.

By linking this detection sensor (7) with the start switch (8) that starts the dryer, the detection sensor (7)
Since the dryer is started by operating the start switch (8) only when 7) detects that the switching valve (5) is in the closed state, it is possible to forget to operate the switching valve (5). Even if there is a problem, the grains stored in the dryer will not be discharged to the outside of the dryer.
