  In the embodiment, as shown in FIG. 12, the second exhaust pipe 57 is piped in the space between the double wind tunnels 63, 63 having a double structure. There is a risk of quality degradation due to the heat of the object. In order to prevent this, in this example, a temperature sensor 64 is installed on the upper surface of the Kara wind tunnel 63, and when the detection result of the temperature sensor exceeds the set temperature, an alarm device (not shown) is activated to make the operator recognize it. Therefore, it is possible to prevent deterioration in quality due to fire or heat of the processed material.

  An exhaust gas introduction switching valve 65 is provided near the branch portion from the exhaust pipe 55 to the second exhaust pipe 57, and an alarm is issued based on the detection result equal to or higher than the set temperature by the temperature sensor 64, and at the same time, the exhaust gas introduction switching valve 65 is provided. Can also be configured to block the introduction of exhaust gas into the threshing machine.

  The temperature sensor 64 may be provided on the start end side of the grain sieve 54 as shown in FIG. Further, by arranging the triangular space between the double wind tunnels 63, 63 of the tangy tang 44 and the tangled wind guide plate 66 with a heat storage body (fluid) 67 such as oil, the temperature distribution can be differentiated. Temperature changes due to fluctuations in work load are reduced, a stable temperature can be maintained, and deterioration in quality due to fire and heat of processed materials can be prevented.

  Further, the number of the heat radiating plates 59 provided in the second exhaust pipe 57 is larger (dense) on the counter feed chain side (point side) of the handling chamber than on the feed chain 11 side (stock source side) of the handling chamber. By doing (refer FIG. 10), the leakage wet material from the treatment room tip side with many processed materials can be warmed efficiently, and wet material adaptability will improve.

  As shown in FIG. 14, the exhaust gas introduction switching valve 65 is configured so that the exhaust can be switched between the first exhaust pipe 56 side and the second exhaust pipe 57 side. It is configured to switch to the first exhaust pipe 55 side when switching or not working. Then, by linking this switching of exhaust with the on / off operation of the cutting / removing clutch lever 68, the operator can save the operation and can efficiently warm the wet material. In addition, when the switching of the exhaust is interlocked with the threshing clutch lever, the operator can work comfortably by shutting off the exhaust toward the second exhaust pipe 57 during the handling operation.

  The embodiment shown in FIGS. 15 and 16 will be described. The cleaning port lids 70 and 70 for opening and closing the cleaning port at the bottom of the receiving port of the first transfer spiral 45 and the second transfer spiral 46 are interlocked with each other so as to swing and open around the opening / closing operation shaft 71. Each of the cleaning mouth lids 70 and 70 is configured to swing and open with the rotation of the opening / closing operation shaft 71 through the link mechanism 72, and the opening / closing operation shaft 71 protrudes in the left-right direction from the shaft core. In addition, an operation handle 73 having grip portions 73a and 73b that can be gripped with both hands is attached to both left and right ends. According to this operation handle, it can be rotated by holding the grips at both the left and right ends, so that the opening and closing operation of the cleaning mouth cover can be performed with an extremely light operation force as compared with a single lever system. Further, the operation handle 73 can be made longer by disposing the operation handle 73 outside the drive pulleys 74 and 75 of the first transfer spiral 45 and the second transfer spiral 46, and the operation load can be further reduced. .
