However, according to the configuration disclosed in this publication, in order to drive the fried grain spiral conveyor from the No. 1 spiral conveyor, the connecting case I understand the opposite and am transmitting it.

Therefore, in the case of a threshing machine that is mounted on a traveling device as a self-propelled self-extraction machine where the ground clearance at the bottom of the machine is not high due to this horizontally mounted drive shaft, the grain supply port to the handling room tends to be high, making it difficult to feed the grain. It is not easy to supply culms,
Furthermore, if this drive shaft is horizontally suspended below the bottom, problems such as the straw rods getting wrapped around the shaft arise.

(c) Problems to be solved by the invention As described above, in the conventional configuration, in order to drive the fried grain spiral conveyor from the No. 1 spiral conveyor, the No. 1 spiral conveyor is suspended horizontally in the body below. Since the power is transmitted between the connecting case and the opposite side through the drive shaft, the horizontally mounted drive shaft increases the ground clearance at the bottom of the machine. The grain culm supply port to the handling room tends to be high, making it difficult to feed the grain culm.Furthermore, if this drive shaft is placed horizontally under the bottom, problems such as the straw rods getting wrapped around occur. Therefore, in the present invention, the transmission mechanism for driving the grain frying spiral conveyor from the No. 1 spiral conveyor is provided on the connecting case side, and the transmission mechanism is covered with a safety cover to make it safe. However,
The cleaning port for removing paddy stuck in the transfer section of paddy from the No. 1 spiral conveyor to the grain frying spiral conveyor or cleaning this section can be easily opened and closed from the outside, making it convenient to remove paddy from the cleaning port. It was devised with the aim of providing a simple structure that will not cause the phenomenon that the paddy or the like gets caught in the transmission mechanism when removing the rice or the like.

That is, the terminal end of the No. 1 spiral conveyor is visible in the lower part of the connecting case that has an overflow port above, and the starting end of the grain frying spiral conveyor is visible below the terminal end, and the above-mentioned grain frying is carried out in the connecting case. A cleaning port is provided on the outer surface of the base at the joining part of the No. 1 spiral conveyor and the grain frying spiral conveyor by connecting the bases of the grain lifting cylinders housing the grain spiral conveyor, and providing a cleaning opening with a lid that can be opened and closed by a freely opening/closing device. At the same time, the transmission mechanism for driving the fried grain spiral conveyor from the No. 1 spiral conveyor provided above the cleaning opening is covered with a safety cover, and the openable/closable tool is located outside the safety cover when viewed from the side. It was constructed in this way.

(E) Effect With this configuration, the grain lifting spiral conveyor is transmitted from the No. 1 spiral conveyor by the transmission mechanism, and the paddy conveyed by the No. 1 spiral conveyor is transferred to the base of the grain lifting tube within the connecting case. The grains fall into the frying cylinder and are lifted up by the spiral conveyor.

At this time, if the grain frying tube becomes clogged and grain frying becomes impossible, the paddy continuously conveyed by the No. 1 spiral conveyor will overflow from the overflow port of the connection case.

In that case, the transmission mechanism is covered with a safety cover and the paddy from the No. 1 spiral conveyor is lifted up by the grain frying spiral conveyor in a safe state, and the opening/closing lid is opened to open the cleaning port and the paddy is lifted up from the No. 1 spiral conveyor in a safe state.
