Description

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

Conventional technology Conventionally, there was a storage chamber in the upper part for storing grains, a drying chamber in the lower part for drying the grains, and a transfer spiral to collect the grains flowing down from the drying chamber and transfer them to one side. A floating grain shelf is installed inside the machine to form a V-shaped grain collecting room when viewed from the front, and this flowing grain shelf is equipped with a tensioner for feeding grain into the grain collecting room from a grain feeding device installed outside the machine. An on-off valve is provided to open and close the inlet, and when loading grain, the on-off valve is manually operated to open to add grain, and when loading is completed, the on-off valve is manually closed. It was a grain loading device to be operated.

Problems to be Solved by the Invention When loading grain into the dryer, manually operate the on-off valve that opens and closes the loading port of the grain rack, and leave the on-off valve open to remove the grain from outside the machine. When the grains are fed to the grain feeding device installed in the grain feeding device, the fed grains are pulled from the grain feeding device into the grain collecting chamber through the loading port, and are transferred to one side by the transfer spiral inside the grain collecting chamber. The grains are transported to the upper part of the grain raising machine.
When the amount of grains supplied into the storage chamber reaches a predetermined amount, the stakeout operation is stopped, and at the same time, the opening/closing valve is manually operated to the closed state. In this dryer, which starts the drying operation and then dries the grains, the opening and closing of the on-off valve is manually operated, so it is possible to forget to close the on-off valve and start the drying operation. If you forget to carry out the drying operation with the opening open, outside air will be sucked in through the inlet, which may reduce the drying speed of the grains.

Means for Solving the Problems This invention has a storage chamber (1') for storing grains in the upper part, a drying chamber (2) for drying the grains in the lower part, and a drying chamber (2) for drying the grains. A grain rack (5) is provided which is equipped with a transfer spiral (3) that collects grains flowing down and transfers them to one side, forming a grain collection chamber (4) that is V-shaped when viewed from the front. The shelf (5) is equipped with an open/close valve (7) that opens and closes a loading port (9) for loading grain from a grain feeding device (6) provided outside the machine into the grain collection chamber (4). ), and the opening/closing of the on-off valve (7) is linked to the operation of an operating device (8) that starts, stops, etc. the grain feeding device (6). The structure of the grain feeding device is as follows.

Effect of the Invention When carrying out the work of loading grain into the dryer, when operating the operating device M (8) that starts the grain feeding device (6) provided outside the dryer, the operation is linked to this operation. Grain collection room (
The opening/closing valve (7) that opens and closes the loading port (9) of the flowing grain shelf (5) forming the grain shelf (4) is in the open state, and the grain feeding device (6)
When the grains are supplied to the grain collecting trough (4), the supplied grains are inserted into the grain collecting chamber (4) from the grain feeding device (6) through the collecting port (9). ) is transferred to one side by the transfer spiral in the grain elevator, and is transported to the upper part by the grain raising machine to the storage chamber (1).
When the amount of grains fed into the storage chamber (1) reaches a predetermined amount, the grain feeding device (6) is stopped and at the same time the operating device (8) is operated. The grain supply device (6) is stopped, and in conjunction with this stop, the on-off valve (7) is stopped.
) becomes closed and the tensioning work is completed, after which the grain drying work begins to dry the grains.

Effects of the Invention This invention provides an on-off valve (7) that opens and closes the loading port (9) into which grains are loaded in conjunction with the operation of the operating device (8) that starts and stops the grain feeding device (6). By opening and closing the on-off valve (7), there is no chance of forgetting to close the on-off valve (7) while drying the grains, which prevents the drying speed of the grains from decreasing, and also prevents the drying of the grains from slowing down during the tensioning work. It also becomes easier to operate.
