[Problems to be Solved by the Invention] Since the known bearing housing d is integrally constructed with the outer case C and the connecting portion e, the connecting portion e between the case C and the bearing housing d is connected to the grain conveying passage. block the
There was a problem that transportation was not carried out smoothly. Also,
Since the cleaning window f cannot be opened at the connection part e of the case C with the bearing housing d, the cleaning window f cannot be opened.
Another issue was that the opening area could not be increased, making cleaning difficult. [0004] When connecting and supporting bearings and housings to L-shafts and cases, it is better not to make them into an integral cast structure from the beginning as in the known example, but to connect separate pieces later with something like screws. , the connection part becomes very small,
Grain flow is extremely improved. In addition, assembly becomes easier. [0005]

[0017] Note that the auger metal 15 is used for various connection parts, and the connection parts are not limited. For example, the lower fixed cylinder part 11 described above can also be used as a horizontal cylinder member provided on the grain tank 9 side. Of course, it is also possible to connect a vertical cylinder member to the auger metal 15 to make it separable. [0018]

[Effect] Next, the effect will be described. When the machine moves forward, the grain culms in the field are divided by the weed cutting body 5, the grain culms divided by the weed division body 5 are pulled up by the pulling device 6, and the grain culms pulled up by the cutting blade 7 are reaped. The grain is supplied to a threshing device, threshed in the threshing device, and temporarily stored in a grain tank 9. When a certain amount of grain is stored in the grain tank 9, the machine is moved to a light truck waiting near the field and the grain frying device 10 is activated. The inflowing grain is fried by the spiral conveyor 16 in the drive side outer cylinder 12 to the end of the drive side outer cylinder 12,
Enter the drive side case 20 of the Auger Metal 15. [0019] The rotation of the spiral conveyor 16 is caused by the rotation shaft 2.
5→bevel gear 24→bevel gear 27→rotary shaft 28→rotary shaft 29, and rotates the intermediate helical blade 30. Then, the rotation of the rotating shaft 29 is transmitted to the rotating shaft 28''→bevel gear 27''→bevel gear 24''→rotating shaft 25'', thereby rotating the passive spiral conveyor 18. Grain is intermediate spiral wing 30
The grain enters the passive outer cylinder 13 through the passive case 21, and is discharged into the tank of the light truck by the passive spiral conveyor]8. [00201 In this case, the auger metal 15 connecting each cylindrical member of the conventional fried grain discharging device 10 is made of cast metal and is connected to the outer case 20.21 and the inner bearing housing 2.
2.22゛ were integrally formed, so the movement of grains could not be carried out smoothly.Also, since the opening area of the cleaning window 36.36゛ could not be formed large, it was not easy to clean it after the work was completed. Ta. [00213 The auger metal 15 of the present invention has an outer case 20.21 and a bearing housing 22.22' on which the inner bevel gear 24 and the like are preliminarily mounted. A fitting hole 31.31'' is formed at the intersection of one cylindrical portion 23.23'' and the other cylindrical portion 26.26'', and a screw hole 32.32'' is formed in the case 20.21. Then, insert the screw groove 34.34'' of the pin 33.33'' into the screw hole 32.
Screw in 32゛, the tip of pin 33.33゛ 35.3
When the bearing housings 22 and 22' are fitted into the fitting holes 31 and 31', the bearing housings 22 and 22' can be fixed to the case 20 and 21. Therefore, a wide space can be formed in which the grains move within the cases 20 and 21, and the grains can be transported smoothly. [0022] Furthermore, a cleaning window 36.36'' is opened at the corner of the case 20.21, but the case 20.2
1 has no connecting portion with the bearing housing 22.22', so the opening area of the cleaning window 36.36' can be formed large. When the pins 33, 33' are removed, the lid members 37, 37' can be easily removed from the case 20, 21, making cleaning work easier. [0023]

[Effect] The present invention provides relative rotation between the starting end of the driven side outer cylinder 13 surrounding the driven side spiral conveyor 18 and the terminal end of the driving side outer cylinder 12 surrounding the driving side spiral conveyor 16 via the auger metal 15. In a device in which the spiral conveyor 16 is movably connected and the rotation of the spiral conveyor 16 is transmitted to the spiral conveyor 18 via a transmission mechanism in the auger metal 15,
The auger metal 15 includes a case 20 fixed to the drive-side outer cylinder 12 side, a bearing housing 22 in which bevel gears 24 and 27 provided separately and independently from the case 20 are mounted inside the case 20, and It is composed of a case 21 fixed to the side outer cylinder 13 side and a bearing housing 22' in which bevel gears 24'', 27'' provided independently from the case 21 are mounted inside the case 21, and the bearing housing 22 .22" is the auger metal of the grain discharge device which is supported by the case 20.21 by pins 33.33". [00241■ In the conventional type, the bearing housing is Since the case and casting are integrally constructed, the connecting part has a large area, so it is difficult for grain to pass through. However, in the present invention, the bearing housing 22.22° is connected to the case 20.2] by the pin 33.33°. Since it has a supported structure, it can be connected in a small area and grains can pass through easily. [0025] ■ In the conventional bearing housing, the outer case and the outer case were integrally cast, so assembling the bevel gear was troublesome, but in the present invention, the bearing housing 22.22゛ is a pin 33.33゛. Since the structure is such that they are each supported later by the cases 20 and 21, assembly is easy. ■Although the case 20.21 has conventionally been provided with a cleaning window, in the present invention, since the connecting portion is small as described above, the opening area of the cleaning window 36.36'' can be increased, making cleaning work easier. It has the effect of being effective.
