BACKGROUND OF THE INVENTION 1. Field of the Invention The present invention relates to a stuck amount detecting device for a grain dryer or the like.

[0002]

2. Description of the Related Art Conventionally, grains are dried by being exposed to the dry hot air by passing the dry hot air through the drying chamber while being fed and circulated while being fed from the grain storage chamber to the grain drying chamber. Then, when the moisture content of the grain being dried reaches the finishing target moisture content, the drying of the grain is stopped. When starting this drying operation,
The amount of grains to be loaded into the storage chamber is such that a plurality of strain sensors provided in a plurality of rows in the storage chamber at predetermined intervals in the storage chamber and a control panel of an operation mechanism for operating the operation are installed on the storage chamber upper side. Through the provided relay case, the respective amount sensors connected to each connector and each cord are sequentially pressed by the grain pressure from the lower part for each row to turn on, and by this turning on, a predetermined voltage value is controlled as a signal. It was a grain input amount detection device that is input to the board and the input grain amount is detected by this input. For example, a dry hot-air temperature is set according to the detected amount of grain and the set type of grain, and dry hot air having the set temperature is generated to dry the grain.

[0003]

The grains stored in the grain storage chamber of the grain dryer are such that hot dry air passes through the drying chamber while being fed out from the storage chamber to the grain drying chamber and flowing down. Thus, the grain is dried by being exposed to the dry hot air, and when the moisture content of the grain being dried reaches the finishing target moisture, the drying of the grain is stopped.

At the start of this drying operation, the grains that have been stretched into the storage chamber have a plurality of strain sensors installed in the storage chamber in a plurality of rows at predetermined intervals in the vertical direction. It is turned on by being pressed by the grain pressure, and a predetermined voltage value is input as a signal to the control panel of the operation mechanism by this ON,
The input grain amount is detected by this input, for example, the dry hot air temperature is set according to the detected grain amount and the set grain type, and the dry hot air at the set temperature is generated to generate the grain. The grains are dried.

In a machine having a large amount of grain to be stuck, the amount of pulling sensor also becomes large, so that there are many connectors and cords for connection through the relay case, which makes mounting difficult, but this is reduced. To improve the external appearance and the mounting.

[0006]

According to the present invention, while the grains are being fed from the grain storage chamber 9 in the upper part to the grain drying chamber 10 in the lower part and flowing down, the grains are exposed to dry hot air to be dried, and the storage is performed. In the chamber 9, a plurality of stake-in sensors 3 provided in a plurality of rows at predetermined intervals in the vertical direction are sequentially relayed above the storage chamber 9 by ON / OFF by a predetermined digital voltage value signal for each row by a grain pressure from the bottom. It is input to the stake-in control panel 8'provided in the case 7 ', converted into an analog signal by the stake-in control panel 8', and input to the control panel 41 provided in the operating mechanism 16 to detect the amount of the stuck grain. A configuration of a stake amount detecting device such as a grain dryer characterized in that.
