配置したことにある。A feature of the present invention is that a feed blade for guiding a processing object flowing in a circumferential direction of a handling cylinder in a direction of an axis of a handling cylinder is fixed to a top plate of a handling chamber, and the processing object is used. The oscillating sensor is disposed close to the feed blade on the downstream side in the processing object flow direction, and a pivot portion for swingably supporting the sensor is disposed on the upper side of the guide surface of the feed blade in the processing object guide direction, In an axial-flow threshing device in which the free end of the sensor is disposed on the lower side of the guide surface from the end of the guide surface, the second feed vane for guiding the work from the feed blade is connected to the sensor in the flow direction of the work with respect to the sensor. It is fixed to the top plate in a state close to the lower side, and the guide surfaces of both feed blades are arranged on substantially the same virtual plane.

より脱穀性能を十分に向上できる。In other words, by bringing the second feed blade closer to the downstream side of the process flow direction of the processing blade with respect to the sensor arranged closer to the process flow direction side of the feed blade, the guide action of both feed blades causes the vicinity of the sensor. In this way, the reverse flow of the processed material to the back side of the feed blade can be sufficiently and reliably suppressed, and the processed material is sufficiently prevented from being caught on the sensor pivot and the flow disturbance, thereby preventing the sensor from malfunctioning in a highly reliable state. it can. Further, since the guide surfaces of the two feed blades are arranged on substantially the same virtual plane, the processed material can be smoothly guided over a sufficiently long distance by the two feed blades, and the flow disturbance of the processed material can be more reliably suppressed. Threshing performance can be sufficiently improved by smooth transfer of the processed material in the processing chamber.

The guide surface 1b is arranged on substantially the same imaginary plane, and the workpiece flowing in the circumferential direction of the handling cylinder is guided in the axial direction of the handling cylinder by a long distance between the two feed blades 11a and 11b. It is configured so that turbulence in flow can be suppressed. The sensor 13 oscillated by the processing object is disposed closer to the first feed blade 11a on the lower side in the processing object flow direction, and the second feed blade 11b is positioned closer to the sensor 13 on the lower side in the processing object flow direction. The pivotal support 13a that is arranged and swingably supports the sensor 13 is disposed on the upper side of the guide surface end 11c of the first feed blade 11a and the guide surface start end 11d of the second feed blade 11b, in the processing object guide direction, The free end of the sensor 13 is disposed on the lower side in the workpiece guide direction from the guide surface end 11c and the guide surface start 11d, and the workpiece toward the back side of the feed blade near the sensor 13 is guided by the two feed blades 11a and 11b. The configuration is such that reverse flow is suppressed, and malfunction of the sensor 13 due to the processing object being caught on the sensor pivot 13a can be prevented. During operation, the sensor 13 is formed so as to come into contact with the second feed blade 11b so as to be in a posture with a small amount of protrusion toward the guide surface,
As shown in FIG. 4, the height X of the guide surface end 11c of the first feed blade 11a, the height Y of the sensor 13, and the second
The height Z of the guide surface start end 11d of the feed blade 11b is set to be higher toward the former. The movable feed blades 12 are rotatably mounted around the support shaft 14, and all the movable feed blades 12 are connected to the interlocking rods 15, so that the feed angles of all the movable feed blades 12 can be adjusted according to the type of the workpiece. It is configured to be adjusted by 15 driving devices. As shown in FIGS. 5 and 6, in the bucket conveyor 9 for supplying the first item to the Glen tank, the support shaft 19 of the lower sprocket 18 with respect to the chain 17 to which the bucket 16 is attached is removably bolted to the case body 20. Two connected lids 2
1, 22, and over the bearings 23 attached thereto, the lids 21, 22, the support shaft 19, the lower sprocket 18
And a cover 24 for preventing grains falling in the case main body 20 from falling on the lower sprocket 18.
It is mounted in a cantilever shape so that it can be integrally attached to and detached from the device 1.
