Description

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

2. Description of the Related Art Conventionally, a paddy flow sensor is provided to detect the flow of grains to be put into a storage chamber, and a paddy flow sensor is installed in the storage chamber to detect the full amount of grains in the storage chamber. A full-load warning device is installed to issue an alarm when the rice-filling amount sensor detects the full amount, and when the grain is put into the storage chamber of the dryer, the paddy flow sensor is in the cut-off state in which it does not operate. Then, set the full quantity alarm device to the activated state and perform tensioning work. When the tensioning amount sensor detects the full quantity, the full quantity alarm device will activate and issue an alarm. At the same time as stopping the filling operation, the device turned off the full warning device so that it would not operate.

Problems to be Solved by the Invention When carrying out the tensioning work in which grains are pushed into the storage chamber of the dryer, the paddy flow sensor is set to the off state, which does not operate, and the full amount warning device is set to the activated state. When the storage chamber is filled with grains during operation, the filling amount sensor detects this full amount, and the full amount alarm device is activated in conjunction with this detection and issues an alarm. In the dryer of type 5, in which the paddy flow sensor and the full gage warning device are operated in the off state at the same time as the piling operation is stopped, if the paddy flow sensor and the paddy gage warning device are operated incorrectly, for example, the paddy If the flow sensor remains in the activated state, the paddy flow sensor will be activated if the grain tensioning is cut off midway, and if the full amount alarm remains in the off state, in which it is not activated, Even if the loading amount sensor detects the full amount of loaded grains,
There are cases where the full capacity warning device does not issue an alarm, and this is an attempt to solve these problems.

Means for Solving the Problems The present invention provides a paddy flow sensor (2) for detecting the flow of pitched grains into the storage chamber (1), and also includes a paddy flow sensor (2) in the storage chamber (1). A filling amount sensor (3) that detects the full amount of grain in the storage chamber (1) and this filling amount sensor (3)
The paddy flow sensor (2) is equipped with a full capacity alarm device (4) that issues an alarm when the full capacity is detected. When the loading amount sensor (3) detects the full amount of grain while detecting the flow of grains, the g alarm device (4) is activated, but when the loading operation is stopped, this alarm device (4) is activated. ) is configured with a grain full warning system for a grain dryer, which is characterized by being equipped with an alarm control device that does not activate the grain dryer.

Effect of the invention Operate the stakeout work start switch and dry! ! When the dryer is started and grain is loaded into the storage chamber (1) of the dryer, the paddy flow sensor (2) detects the flow of the loaded grain. When the inside of the storage chamber (1) becomes full with grains during this detection, the filling amount sensor (3) detects this full amount, and along with this detection, y
A four-volume alarm device (4) issues an alarm.

When the grain tensioning is stopped when the alarm is issued, the paddy flow sensor (2) no longer detects the flow of the staked grains, and when the flow is no longer detected, the full amount warning device (4) stops issuing the alarm.

Effects of the Invention According to the present invention, during the tensioning operation in which grains are tensioned into the storage chamber (1) of the dryer, while the flow of the grains to be tensioned is detected by the paddy flow sensor (2), the amount of tensioning is detected. The sensor (3) is connected to the storage chamber (
i) When a full amount of grain is detected, the full amount alarm device (4) activates and issues an alarm, and when the loading of grains is stopped, the paddy flow sensor (2) ) no longer detects the flow of grains, and when it stops detecting it, the operation of the full amount alarm device (4) stops and the generation of the alarm automatically stops, so the paddy flow sensor (2) and the full amount Alarm device (4)
There is no need to perform on/off operations, which makes the tensioning work easier and eliminates problems caused by erroneous operations.
