When the grains are put into the tank 2 from the grain supply cylinder 8, the grains are accumulated while being evenly scattered by the equalizer 9 provided in the upper center part of the tank 2. When the grains are accumulated in the tank 2, dry air is sent from the burner 4 into the tank 2, and exhaust air is sucked by the suction fan 6. Then, the stirring screw 23 revolves around the inside of the tank 2 while revolving, and stirs and flows the grains from the upper layer of the grain in the tank 2 to the lower layer near the upper surface of the floor plate 10.

That is, in the revolution of the stirring screw 23, the rotation output is directly transmitted to the guide arm 21 by the operation of the guide arm drive motor 22 attached to one end of the guide arm 21, and the other end of the guide arm 21 is transmitted. A roller 20 axially mounted on the rail 20 is provided around the inner wall surface of the tank 2.
It is done by proceeding. When the stirring screw 23 revolves around the revolution, since the guide arm 21 is laterally mounted on the hanger frame 19, the hanger frame 19 rotates about the axis of the support pipe 18. At this time, since the axis of the guide arm 21 and the axis of the support pipe 18 are orthogonal to each other, the power supply cable 46 and the temperature measurement cable 47 for grain temperature detection that pass through the inside of the support pipe 18 are connected to the guide arm 21.
It is avoided that it is twisted by the rotation of and is not affected by cutting or the like.

On the other hand, the parts that revolve in the grain tank 2 together with the guide arm 21 are the hanger frame 19, the connector fixing frame 30, and the motor base 2.
9, a guide arm bearing 31, a power cable 35, a rotary connector rotating part 42, and a relay temperature measuring cable 39.

Therefore, the power supply cable 46 passing through the support pipe 18 which is the fixed portion is branched by the slip ring 34 into the power supply cable 35 which is the rotating portion and connected to the rotation motor 25 of the stirring screw 23.
The power cable 46 in the support pipe 18 is not twisted by the rotation of the guide arm 21. In addition, the grain temperature cable 46 for detecting the grain temperature is the terminal 37 of the slip ring 34.
And is connected to the upper rotary connector 38, and is curved from the upper rotary connector 38 via the temperature measuring cable 39 for relay to the lower rotary connector 40 so as to avoid the guide arm 21. Connected. As a result, as the guide arm 21 rotates, only the relay temperature measuring cable 39 is rotated around the axis of the support pipe 18, so that the grain temperature detecting temperature measuring cables 43 and 47 are twisted and cut. Not affected by.

As another embodiment, the hanger frame 1
In some cases, the upper rotary connector 38 fixed to 9 is not provided. This embodiment will be described with reference to FIG. As shown in FIG. 3, the temperature measuring cable 47 is connected to the inner cavity of the slip ring 34 together with the power cable 46. Then, the power supply cable 46 is branched to the power supply cable 35 which is a rotating portion, and the temperature measuring cable 47 is branched to the temperature measuring cable 48 which is a rotating portion. And the power cable 35
Is connected to the rotation motor 25 of the stirring screw 23 as in the conventional case, while the temperature measuring cable 48 is connected to the lower rotary connector 40 so as to avoid the guide arm 21, the temperature measuring cables 43 and 47 are connected to the guide arm. It is not twisted by the rotation of 21.

When a predetermined grain temperature is detected by the temperature measuring cable 47, the blower 7 is appropriately controlled, and the temperature measuring cable operates reliably and properly.
