[0006]

1 and 3 show a combine embodying an embodiment of the present invention. In front of the undercarriage 2 having the traveling device 1, a mowing device 9 and a supply and transport device 1 are provided.
0 is provided. The cutting device 9 includes a weeding tool 11 for weeding the planted grain culm, a raising case 12 for causing the planted grain culm, a cutting blade 13 for cutting the planted grain culm, and a cutting blade 13 for cutting. A stock transfer device 14 for holding the culled culm and conveying it backward is provided. Behind the stock transfer device 14, a supply transfer device 10 that takes over and transports the grain stems transferred from the stock transfer device 14 is provided.

The reaper 9 is supported by a reaper supporting frame 16 which moves up and down about a fulcrum above the traveling transmission device 15 at a substantially right and left intermediate portion. It is configured to move up and down together with the support frame 16. Above the undercarriage 2, the supply and transport device 10
A threshing device 18 having a feed chain 17 for taking over and transporting grain culms conveyed from the plant; a Glen tank 3 for temporarily storing the grains selected by threshing by the threshing device 18;
The operation unit 21 is mounted. Behind the threshing device 18, a culm chain 19 that takes over and conveys the culm conveyed from the feed chain 17,
Is provided with a cutter 20 for cutting the culm.
Further, instead of the cutter of this embodiment, another working machine such as a knotter for binding the culm may be attached.

In addition, a vertical auger 4 and a horizontal auger 5 are provided for discharging grains in the Glen tank 3 to the outside of the machine. When the grains in Glen Tank 3 are full,
By setting the grain discharge lever (not shown) provided in the operation unit 21 to the on state, the lower spiral (not shown) in the Glen tank 3, the spiral in the vertical auger 4, the horizontal auger 5
The spiral 5a in the inside is rotationally driven to discharge the grains in the Glen tank 3 to the outside of the machine.

In the combine having the above-described configuration, as shown in FIG. 3, in the discharge guide tube 8 provided at the distal end of the horizontal auger 5, the grain passage in the discharge guide tube 8 has a grain passage. The left and right side walls are configured to protrude from the outside to the inside and become narrower from the upper side to the lower side discharge port 7 in the grain discharging direction. That is, FIG. 3B shows a cross section taken along the line S1-S1 of FIG. 3A. The side portions 8a of the discharge guide tube 8 are pressed to form left and right projecting portions 8a.
b, 8b, and the upper ends of the left and right protruding portions 8b, 8b are brought closer to the end of the spiral 5a. Then left
Wide grain drop passages 8c, 8d are formed before and after the right protrusions 8b, 8b in the grain discharge direction. FIG. 4 shows a perspective view thereof.

As a result, the number of parts is reduced and the cost is reduced. In addition, since the discharge port 7 is narrow, it is possible to prevent the hand of the operator from entering and it is safe. Next, FIGS. 5 to 7 will be described. The grain tank 3 for temporarily storing grains is composed of an upper grain tank 3a and a lower grain tank 3b. The upper Glen tank 3a is made of resin and the lower Glen tank 3b
Is configured to be detachable. The upper edge portion 22 of the lower Glen tank 3b is formed wide by bending a plate. In addition, the edge 23 at the lower end of the upper Glen tank 3a is also made wider at the time of molding. Therefore,
The upper Glen tank 3a can be stably mounted on the lower Glen tank 3b.

Further, in order to fix the upper Glen tank 3a more stably, the upper Glen tank 3a is fixed to an auger receiver 25 installed at the upper part of the first deep-frying cylinder 24 by a hook 26. The lever 26a and the pin 26c of the hook 26 are provided on the upper Glen tank 3a side, and the pin 26b is fixed on the auger receiver 25 side. When the pin 26c is engaged with the pin 26b to lock the lever 26a, the upper Glen tank 3a is fixed and does not move.

However, if the fixing of the above 26 is forgotten, the upper Glen tank 3a is separated from the lower Glen tank 3b. In particular, when traveling on a road at a high speed, the vehicle may depart from the vehicle due to the influence of wind pressure, vibration, or the like, which is dangerous. Therefore, when the holding rod 27 is attached to the horizontal auger 5 and the horizontal auger 5 is stored in the auger receiver 25, the holding rod 27 is brought into contact with the upper part of the upper Glen tank 3a. Accordingly, even if the hook 26 is forgotten to be fixed, the upper Glen tank 3a is pressed by the presser bar 27, so that the upper Glen tank 3a is separated from the lower Glen tank 3b due to wind pressure, vibration or the like while traveling on a high speed road. Can be prevented. Since the upper Glen tank 3a is formed of resin, it is preferable to attach an elastic body such as rubber to a portion of the pressing rod 27 that contacts the upper Glen tank 3a. Presser bar 27
It may be made of resin.

In another embodiment, a hole (not shown) may be formed in the upper part of the upper Glen tank 3a, and the pressing rod 27 may be inserted into the hole.
Of course, when the grain is stored in the Glen tank 3 during the operation, the horizontal auger 5 is stored in the auger receiver 25 and the hole is closed, so there is no problem. A configuration for raising and lowering the horizontal auger 5 will be described.

A gas damper 28 is provided between the vertical auger 4 and the horizontal auger 5, so that the horizontal auger 5 is always urged upward. For this reason, while the lateral auger 5 is being stored in the auger receiver 25, it is necessary to lock the auger 5 so as not to rise. The lock portion 29 is configured such that a U-shaped pin 29a fixed to the horizontal auger 5 is hooked by a hook 29b provided on the auger receiver 25 side. When the hook 29b is released, the horizontal auger 5 is raised by the urging force of the gas damper 28.

The turning of the vertical auger 4 in the left-right direction in plan view is such that the operator himself grips the handle 30 of the horizontal auger 5 and turns the same with the horizontal auger 5 to an arbitrary position. As described above, since the horizontal auger 5 is always urged upward by the gas damper 28, the urging force of the gas damper 28 needs to be increased so as not to fall naturally. As a result, for example, when working with the horizontal auger 5 lowered, the operator must work hard and labor is required.

To solve such a problem, FIG.
And a configuration as shown in FIG. That is, the plate 31 is provided between the horizontal auger 5 and the vertical auger 4, and the plate 31 is rotatable about a fulcrum 32 on the vertical auger 4 side, and the pin on the tip side is a slide rail 33 on the horizontal auger 5 side. It is configured to slide between. The gas damper 28 is loosely fitted on the plate 31.

Thus, when the horizontal auger 5 is lowered, the fulcrum of the gas damper 28 is moved to A by moving the plate 31.
Since it moves from point to point B, even if you lower the horizontal auger 5,
Since the contraction amount of the gas damper 28 is reduced, the horizontal auger 5
The load when lowering is reduced, and the labor of the operator is reduced.

As described above, according to the present invention, a discharge guide cylinder 8 is provided at the end of the horizontal auger 5 for discharging the grains down, and the side wall of the discharge guide cylinder 8 is inflated inward to form a substantially central portion. Is narrowed, so that it is possible to prevent the hand of an operator from being accessed, and it is safe. In addition, the number of parts is reduced and costs are reduced, and assembly and inspection and maintenance can be performed easily and efficiently.
