Description

[Detailed description of the invention] Industrial application field This invention is capable of detecting the maximum loading amount for each type of grain in a grain dryer that dries multiple types of grain such as paddy, wheat, and beer barley. The present invention relates to a device that does this.

Conventional technology Conventionally, a grain dryer equipped with a type selection dial on the control panel for drying different types of grain such as paddy and wheat is described in Japanese Utility Model Application Publication No. 101191/1983. A grain dryer capable of electrically detecting the height of grain piled up inside the machine body is described in Japanese Utility Model Publication No. 58-24149.

As shown in FIG. 3, the type switching dial in the conventional grain dryer is used to change the drying conditions in the control panel by turning the rotary knob 1 to match the display for paddy, wheat, etc. Also,
As shown in FIG. 4, a conventional device for electrically detecting the height of grain accumulation has electrical contacts 3 arranged in multiple stages in the upper part of the dryer main body 2, which are closed by the accumulation of grain. The structure is as follows.

Problems that the invention aims to solve Generally, in a grain dryer that dries different varieties of grain such as paddy and wheat, when fully loaded with grain of a variety with a small bulk specific gravity,
% drying capacity, and the strength of the dryer body is designed to withstand the weight of the grain. Therefore, for example, in a grain dryer that dries paddy and wheat, paddy with a small bulk specific gravity can be fully loaded, but wheat with a larger bulk specific gravity cannot be fully loaded. If the dryer is full, it will exceed the weight capacity of the dryer, so the maximum amount of wheat that can be loaded must be less than the full amount of paddy.

By the way, in the conventional grain dryer,
Although the amount of grain loaded into the dryer body can be detected in stages, it is not possible to set the maximum amount of grain loaded depending on the type of grain to be loaded.
For this reason, when tacking grain, the operator must be aware of the maximum tacking amount for each type of grain and then monitoring the status of grain tacking, which is not only cumbersome, but also difficult. In some cases, the amount of drying material exceeds the specified amount, which poses a problem in terms of the strength and durability of the dryer.

Means for solving the problems The present invention solves the above problems, and includes:
The contents will be explained below with reference to FIGS. 1 and 2 corresponding to the embodiment.

A grain sensor 102 is provided at the top of the dryer main body 101 to detect the height of stacked grain in multiple stages.
3 is a grain type setting device 10 for setting the type of dry grain;
4 is provided. And the grain setting device 104
In conjunction with this, the detection position of the plurality of grain sensors 103 is changed so as to detect the maximum loading amount for each set type of grain.

Operation When performing grain drying work, the type of grain to be dried is set by operating the grain type setting device 104. When this setting operation is performed, the detection positions of the multiple grain sensors 103 are changed in conjunction with the setting operation so as to detect the maximum loading amount for each type of grain.

Therefore, if the grain set in the dryer body 101 is loaded until the grain sensor 102 detects the grain, the grain will be loaded in the dryer body 101 to the maximum amount for each type. Therefore, the drying capacity can be fully utilized regardless of the type of grain to be dried, and safety can always be ensured without putting the main body 101 of the dryer in an overweight state.

Example An embodiment of the present invention will be described.

In FIG. 1, reference numeral 101 denotes a dryer main body, and a grain sensor 102 is provided in the upper part of the dryer main body 101 to detect the height of stacked grain in multiple stages. This grain sensor 102 is a plurality of electrical contacts that are closed by the grain stacking pressure, but any other suitable sensor such as one that detects the grain stacking height using ultrasonic waves may be used. 1
03 is a control panel of the dryer, and the control panel 103 is provided with a grain type setting device 104 for setting the type of dried grain. In the illustrated example, the grain setting device 104
Paddy, wheat, and beer barley are now available. This grain type setting device 104 and the grain sensor 10
2 are linked as follows. That is, when the grain type setting device 104 is set to paddy, the highest value of the grain sensor 102 becomes valid, and when it is set to wheat or beer barley, the lowest value becomes valid. In the case of wheat and beer, the height of the piled grain is set so that the maximum amount is reached at several tens of percent or less than the full amount, as shown in b, in the case of wheat and beer barley. The circuit is configured to be detected. Furthermore, since the bulk specific gravity of the former is small and the bulk specific gravity of the latter is large between paddy and wheat, it is assumed that the maximum tensioning amount (full amount) of the paddy and the maximum tensioning amount of the wheat are equal. Become.

In the apparatus configured as described above, when the type of grain is set using the grain type setting device 104 when performing drying work, the grain sensor 10
2 is in a state to detect the maximum loading amount for each grain, so the grain sensor 10 is installed inside the dryer main body 101.
By tensioning the grain until the sensor 2 is activated, it is possible to reliably tension the grain to the maximum amount for each type of grain. Therefore, by performing drying work in this state, the dryer can utilize its full capacity regardless of the type of grain. Moreover, the dryer main body 101 does not become overweight depending on the type of grain, and drying work can always be carried out safely.

Effects of the Invention In short, the present invention is configured as described above, so that by simply setting the type of grain using the grain setting device 104 of the control panel 103, the grain sensor 102 detects the maximum loading amount corresponding to the grain. By charging the grain until the grain sensor 102 detects the grain sensor 102, the grain can be reliably loaded to the maximum loading amount for each type of grain.
Regardless of the type of grain being dried,
It is possible to perform the drying operation at 100%, and moreover, the drying work can be carried out safely at all times without causing the dryer main body 101 to fall into an excessively heavy state.
