The auger for frying 18 is rotatable toward the lower metal 14, but has a fixed cylinder 23 fixed in the vertical direction and a movable cylinder 24 moving up and down with respect to the fixed cylinder 23. The moving cylinder 24 is formed so as to be vertically movable with respect to the fixed cylinder 23 so as to be able to expand and contract the whole height of the auger for frying 18. The expansion / contraction configuration is arbitrary, but as an example, the rotation transmission shaft 25 is mounted on the bearing 16 in the lower metal 14 to which the base of the fixed cylinder 23 is attached,
The rotation of the rotation center shaft 11 is transmitted to the rotation transmission shaft 25. Different diameter portion (square axis) 26 on the upper side of the rotary transmission shaft 25
The base of the hollow shaft 27 is fixed to the upper end of the hollow shaft 27, and a cylindrical member 28 is fixed to the upper end of the hollow shaft 27. The cylindrical member 28 is rotatably mounted on a bearing 29 provided at the tip of the fixed cylinder 23. The fixed spiral wing 30 is attached to the above.

In the movable cylinder 24 fitted to the outer periphery of the fixed cylinder 23, there is provided a telescopic spiral wing 31 whose length can be expanded and contracted in accordance with the expansion and contraction of the movable cylinder 24. The telescopic spiral wing 31 is provided by providing a plurality of spiral wing pieces 32 slidably only on the rotary sliding shaft 33 and changing the interval between the spiral wing pieces 32 by the expansion and contraction of the moving cylinder 24.

Reference numeral 41 denotes an opening at the other end of the large-diameter collar 37, and reference numeral 42 denotes a pair of engagement members (pins) for preventing the engagement plate 35 from coming off. Each spiral wing piece 3
2 moves, the engagement plate 35 engages with the engagement body 42 and moves in a chain, but the uppermost spiral wing piece 32X and the lowermost spiral wing piece 32Y on the discharge auger 19 side are
It is fixed to the rotary sliding shaft 33 so as to rotate integrally with the rotary sliding shaft 33 but not move in the axial direction. The base of the rotary slide shaft 33 is slidably fitted to the cylindrical member 28 only, and the upper end of the rotary slide shaft 33 is freely rotatable only on a bearing 45 provided at the upper end of the movable cylinder 24. Attach. Therefore,
The rotating / sliding shaft 33 is rotated by the rotating tubular member 28, and expands / contracts due to expansion and contraction of the tip of the movable barrel 24. When the movable barrel 24 is reduced, the base of the rotating / sliding shaft 33 is housed in the hollow shaft 27.

A first telescopic motor 46 is provided on the fixed cylinder 23 side, a rotary screw shaft 47 protruding upward is attached to the first telescopic motor 46, and a support member 48 is provided on the movable cylinder 24 side. And a hollow rotary shaft 49 is attached to the support members 48 and 48 so as to rotate only freely.

The rotation screw shaft 47 is inserted into the screw shaft, and the engagement protrusion 51 provided on the inner periphery of the hollow rotation shaft 49 is screwed into the screw groove of the rotation screw shaft 47, and the rotation screw shaft 47 and the engagement protrusion 51 are relatively positioned. Rotate to. Therefore, when the first expansion / contraction motor 46 and the second expansion / contraction motor 50 are operated, the expansion and contraction is performed quickly, and when one of them is rotated, the expansion and contraction is performed slowly. Also,
12 and 13 show a second embodiment, in which the number of expansion and contraction motors is one, and a motor mounting plate 53 fixed to the fixed cylinder 23 is shown.
, A base of a support member 54 parallel to the fry auger 18 is fixed to the motor mounting plate 53, a bearing member 55 is provided at an upper end of the support member 54, and the bearing member 55 is rotated by the telescopic motor 46. The tip of the rotating screw shaft 47 is rotatably mounted. A screw hole of a moving body 56 is screwed into the rotary screw shaft 47, and the moving body 56 is fixed to the moving cylinder 24 side. Therefore, the moving body 5 is rotated by the rotation of the rotary screw shaft 47.
6 moves to expand and contract the moving cylinder 24.

Rolling means is provided between the body frame 1 and the traveling frame 60 of the traveling device 2 to make the body frame 1 horizontal with respect to the left-right inclination of the field, and the body frame 1 is kept horizontal with respect to the front-back inclination. Is provided. The rolling means attaches a front link mechanism 62 to a front support metal 61 provided on the body frame 1 side by a front support shaft 63, and axially attaches a front end of a front side arm 64 of the front link mechanism 62 to a front portion of the traveling frame 60. I do. A rear support shaft 65 supported by pitching means, which will be described later, is provided at a rear portion of the body frame 1, and a rear link mechanism 66 is attached to the rear support shaft 65.
The distal end of the rear side arm 67 of the rear link mechanism 66 is pivotally mounted on the rear part of the traveling frame 60. The front vertical arm 68 of the front link mechanism 62 and the rear link mechanism 6
The rear vertical arm 69 is connected to the rear vertical arm 69 by a connecting member 70 so that the rear vertical arm 69 and the front vertical arm 68 rotate simultaneously. Then, the tip of the rod of the rolling cylinder 71 is axially mounted on the rear vertical arm 69,
The base of the rolling cylinder 71 is pivotally attached to the tip of an arm 72, and the base of the arm 72 is pivotally attached to the body frame 1.

Thus, the pitching means 73 is provided at the rear of the body frame 1. Pitching means 73
A pair of left and right pitching support metals 74 is provided at a predetermined position on the rear side of the body frame 1, and both ends of a horizontal pitching horizontal shaft 75 are freely rotatably mounted between the left and right pitching support metals 74. A base of a pitching horizontal arm 76 is fixed to the pitching horizontal shaft 75, and a tip of the pitching horizontal arm 76 is pivotally mounted on an upper part of an arm 78 of a left and right link mechanism support member 77 by a shaft 79. The left and right arms 78 are provided as a pair, and the middle portions of the left and right arms 78 are connected by a horizontal rod. The pair of pitching lateral arms 76
The base of the pitching vertical arm 80 is fixed to one of them, and the pitching rod of the pitching cylinder 81 is mounted on the tip of the pitching vertical arm 80. The base of the pitching cylinder 81 is mounted on the side of the machine frame 1 by being pivoted. Reference numeral 82 denotes a regulating member. The tip of the regulating member 82 is pivotally mounted on the upper part of the arm 78 of the left and right link mechanism support member 77. When the pitching horizontal arm 76 is extended and retracted, the shaft 79 moves to the center of the pitching horizontal axis 75 so that the base of the regulating member 81 pushes the base of the rolling cylinder 71 rearward. And the traveling frame 60 is lowered to relatively raise the body frame 1 and
It is configured to increase the interval between.

In a fixed state in which the pitching cylinder 81 does not expand and contract, the left and right link mechanism support members 77 are not moved, so that the rear support shaft 65 of the rear link mechanism 66 is also not moved. The rolling frame 71 is moved up and down by extending and contracting the rolling cylinder 71 to move the vehicle up and down. In addition, the traveling frame 60, the front link mechanism 62, the rear link mechanism 66, and the connecting member 70 each constitute a parallel link, and if the rolling cylinder 71 does not expand and contract,
When the pitching cylinder 81 is expanded and contracted in this state, the portion of the rear support shaft 65 moves up and down. As a result, the rear side of the parallel link supports the front side of the front side support metal 61. It moves up and down around the axis 63. Thus, the auger for frying 18 is configured so that when the auger for frying 18 is expanded and contracted, the height of the vehicle is simultaneously raised by the rolling mechanism, and the discharging operation is performed easily and quickly. In other words, raising the height of the auger 18 and the discharging auger 19 and raising the vehicle height are:
If they are performed separately, the operation is troublesome, and it takes time to extend the auger for frying 18 and increase the vehicle height. Therefore, by simultaneously performing these operations, the operability is improved and the operation time is shortened.

FIG. 17 shows a second embodiment. When the auger for frying is extended, the body frame 1 on the side where the auger for frying is provided (in the rear side in the embodiment) is simultaneously pitched. It is configured to be raised by a mechanism.
Thus, when the discharge auger 19 is at the overhang position and the aircraft is to be moved backward, the fry auger 18 is extended so as to increase the height of the discharge auger 19, and after the discharge operation is completed. After a predetermined distance, the discharge auger 19
Is configured to return the height to the initial position. That is, even if the tip height of the discharge auger 19 is apparently higher than that of a nearby truck, when the aircraft is run, the tip of the discharge auger 19 may move up and down due to the vibration, and may contact the tank peripheral wall of the truck. When the vehicle moves backward to approach the truck, the height position of the discharge auger 19 is raised. The lifting means extends the fry auger 18 first, then raises the vehicle height by a rolling mechanism, and then raises the body frame 1 on the fry auger 18 side by a pitching mechanism.
However, depending on the height of the discharge auger 19 at that time, the elongation of the auger for agglomeration 18 and the increase in vehicle height by the rolling mechanism may be performed simultaneously.

In the embodiment of FIGS. 20 and 21, the lifting of the discharge auger 19 is automated. The right and left rolling mechanisms and the rear pitching mechanism are operated according to the position of the discharge auger 19, and the discharge auger 19 is operated. When the user turns 19, the right and left rolling mechanisms or pitching mechanisms corresponding to the position are automatically operated. In the embodiment shown in FIG. 22, the body level control by the rolling mechanism and the pitching mechanism is normally performed during the harvesting work, so that the body level control is performed during traveling to the discharge position, and the body level control is performed during the discharge work. Instead, the operation is performed again when the original harvesting operation is returned after the discharging operation is completed. At this time, the vehicle is returned to the vehicle body horizontal control state immediately before the discharging operation is started. That is, as described above, when the tip discharge height of the discharge auger 19 is increased by using the rolling mechanism and the pitching mechanism, the aircraft may not be horizontal, and when returning to the cutting operation, the horizontal control is performed again. Although it is not possible to return to the re-working immediately, but by returning to the state immediately before the start of the discharging work, the horizontal control can be omitted or requires less correction, and the time required for returning to the work can be reduced. FIG. 23 shows a configuration in which the auger for fry 18 is extended when the discharge auger 19 is swung above the Glen tank 8. When turning the discharge auger 19, the base itself is raised, so that the interval with the Glen tank 8 is widened, and the volume of the Glen tank 8 can be increased accordingly.
The degree of freedom in designing the external shape can be increased. Note that when a cabin surrounding the cockpit is provided, when the discharge auger 19 is swung above the cabin, the grain auger 18 may be extended.

[0016]

Next, the operation will be described. Move the fuselage forward and cut
To cut the culm, supply the cut culm to the threshing device 3 and thresh in the threshing device 3 to perform cutting and threshing work. When a certain amount of grains are accumulated in the Glen tank 8, the machine is waiting near the field. Move to the light truck inside. Next, the augmenting auger 18 in the reduced state is extended, and the discharge auger 19 is turned to the position above the tank of the light truck.
The grain discharge device 9, the auger for agitation 18, and the discharge auger 19 are driven to discharge the grains in the Glen tank 8. When the discharging operation of the grain is completed, the discharging auger 19 is stored and the cutting and threshing operation and the discharging operation are repeated. In this case, the tank position of the light truck may be located considerably above the fuselage.
Since the movable cylinder 24 is extended and raised with respect to the fixed cylinder 23 of FIG. 8, the height of the distal end of the discharge auger 19 is increased to enable the discharge operation.

That is, the distal end of the discharge auger 19 rotates upward about the base of the discharge auger 19,
Even if it does not reach, the base itself of the discharge auger 19 rises, so that the discharge operation can be performed even in a place where the discharge auger 19 has not reached without being reached. Also, the discharge auger 19
Is inclined, so that the discharge auger 19 cannot be located far from the frying auger 18. However, when the base of the discharge auger 19 itself is raised, the length of the discharge auger 19 is reduced to the discharge distance. And the range of discharge operation can be extended (FIG. 24). Therefore, when the auger 18 for frying is expanded or contracted, the height of the body frame 1 is raised or lowered by the rolling mechanism in response to the operation, so that the time required to move the tip of the movable barrel 24 up and down is reduced. You can shorten and work faster. That is, the auger for frying 18
Since the vehicle height of the body frame 1 is automatically increased by the rolling mechanism at the same time, the vehicle height is not increased after the augmenting auger 18 is extended, so that the time can be shortened accordingly.

Further, since the height of the auger 18 is raised by the rolling mechanism by the operation of extending the auger 18 for frying, only one operation is required and the operability is improved. Of course,
The auger for frying 18 does not expand or contract only by the operation of raising the vehicle height by the rolling mechanism. When the discharging operation is completed, the auger for frying 18 is reduced and, at the same time, the vehicle height is lowered by the rolling mechanism to return to the original state, thereby improving the operability thereafter. In addition, in the embodiment of FIG. 17, the pitching mechanism is used to extend the auger 18 for frying in parallel with the extension of the auger 18 for frying.
8), the same operation is achieved. Further, it is not clear which of the rolling mechanism and the pitching mechanism can raise the tip position of the discharge auger 19 depending on the specific configuration, but a rolling mechanism or a pitching mechanism that can raise the tip of the discharge auger 19 is automatically selected. It is, of course, possible to perform the operation, and it is also possible to operate the pitching mechanism after rolling, or to operate the rolling mechanism after pitching.

In the embodiment shown in FIGS. 18 and 19, when the discharge auger 19 is at the overhanging position and the aircraft is to be moved backward, the fry auger 18 is extended to discharge the auger 1.
Since the height of the discharge auger 19 is returned to the initial position, the height of the discharge auger 18 is reduced and the height of the discharge auger 19 is returned to the initial position at a predetermined distance after the discharge operation. Even if the tip of the discharge auger 19 moves up and down due to the vibration caused by the vibration, the tip of the discharge auger 19 can be prevented from contacting the tank peripheral wall of the truck. In this case, the H of the continuously variable transmission
Since the above operation is performed simply by moving the ST lever backward, even if the forging operation of the auger for frying 18 is forgotten, it can be prevented from coming into contact with the peripheral wall of the truck, improving operability and ensuring safety. . In the embodiment of FIGS. 20 and 21, the operation of the left and right rolling mechanisms for raising the discharge auger 19 and the operation of the pitching mechanism on the rear side are automated by the position of the discharge auger 19; When the auger 19 is located, the left rolling mechanism is used to raise the left side. When the auger 19 is located at the position b, the rear side is raised by the pitching mechanism. When the discharge auger 19 is located at the position c, the right rolling mechanism is used. To rise. Therefore, the time required for setting the position of the discharge auger 19 is reduced, and the operability is also improved.

In this case, a turning operation part of the auger 18 may be provided at the base of the auger 18. In this case, in particular, after the discharge auger 19 is turned to perform the positioning, the operation of the driver's seat is performed. Although the rolling mechanism or the pitching mechanism is operated by the operation unit, the rolling mechanism or the pitching mechanism is automatically selected and operated according to the position of the discharge auger 19, so that there is no need to return to the driver's seat, and extremely operability is achieved. Improve. Although the expansion and contraction configuration of the auger for frying 18 is arbitrary, the operation in the embodiment will be described. By operating the expansion and contraction switch, one or both of the first expansion and contraction motor 46 and the second expansion and contraction motor 50 are operated. Is operated, the rotary screw shaft 47 and the engagement protrusion 51 rotate relatively, the hollow rotary shaft 49 moves upward with respect to the rotary screw shaft 47, and the movable cylinder 24 is extended with respect to the fixed cylinder 23. On the contrary, when one or both of the first telescopic motor 46 and the second telescopic motor 50 are rotated, the movable cylinder 24 is reduced with respect to the fixed cylinder 23.

In the second embodiment shown in FIGS. 12 and 13,
The rotary screw shaft 47 is rotated by the telescopic motor 46,
The rotation of the rotary screw shaft 47 causes the movable body 56 fixed to the movable cylinder 24 side to move up and down to expand and contract the movable cylinder 24. In this case, the cost is reduced because there is only one telescopic motor. When the movable cylinder 24 moves up and down with respect to the fixed cylinder 23, the spiral wing piece 32 rotates but is slidable with respect to the rotary sliding shaft 33. Since the piece 32X is fixed to the rotary sliding shaft 33 so that it can only rotate and is fixed in position, when the moving cylinder 24 is extended, the spiral wing piece 32X at the tip moves upward, and the spiral wing piece 32X moves upward. The engagement plate 35 moves upward in the large-diameter collar 37, and the engagement plate 35 is moved to the next spiral wing piece 3.
When the engaging member 42 is engaged, the engaging member 42 is pulled and moved, and the respective spiral wing pieces 32 are moved, so that the interval between the respective spiral wing pieces 32 is increased.
4 corresponds to an extension of 4. When the moving cylinder 24 is extended, each spiral wing piece 32 is pulled by the upper spiral wing piece 32, but the spiral wing piece 32 near the lowermost fixed cylinder 23 is moved to the next lower spiral wing piece 32. The independent spiral wing piece 32Y is not pulled by the independent spiral wing piece 32Y, so that the distance between the end of the fixed spiral wing 30 of the fixed cylinder 23 and the independent spiral wing piece 32Y is always constant, and the conveyance due to the presence of bearings and the like is performed. Even if there is resistance, the grain is reliably fried and the transfer of the grain from the fixed cylinder 23 to the moving cylinder 24 is improved.

The interval between the spiral wing pieces 32 is
Even when the moving cylinder 24 is extended to the maximum, each spiral wing piece 3
The second spiral wing body 38 is set so as to be able to fry the grain.
Since the interval between the spiral wing pieces 32 is set by the length of the fitting hole 40 of the spiral wing piece 32,
If the length of each fitting hole 40 is shortened to increase the number of the spiral blade pieces 32, the interval between the spiral blade bodies 38 does not increase. As described above, the fried auger 18 is constituted by the fixed cylinder 23 provided at the vertical position on the fuselage side and the movable cylinder 24 provided to extend and contract with the fixed cylinder 23 so as to be stretchable. The structure of the telescopic spiral wing 31 can be simplified, can be operated reliably, the installation space can be reduced, and the whole combine can be made smaller. When the auger for agitation 18 and the discharge auger 19 are operated, the auger for agitation 18 flies the grains in the Glen tank 8. The rotation of the rotation center shaft 11 of the discharge spiral blade 10 of the discharge device 9 causes the rotation transmission shaft 25 of the lifting auger 18 in the lower metal 14 to rotate via a bevel gear or the like, and the different diameter portion 26 of the rotation transmission shaft 25 is hollow. The shaft 27 is rotated, and the hollow shaft 27 rotates the fixed spiral blade 30 to fry the grains. The rotation of the hollow shaft 27 causes the cylindrical member 28 to rotate, and the rotary sliding shaft 33 slidably fitted only to the cylindrical member 28 to rotate. The engaging plate 35 and the boss 36 of the piece 32 are rotated, and the boss 36 rotates the large-diameter collar 37 to rotate the spiral wing body 38, and the spiral wing body 38 of each spiral wing piece 32 is rotated to expand and contract the spiral wing. 31 functions to fry the grains.

Next, after the above operation is completed, the Glen tank 8
When the inside is empty, the fry auger 18 is reduced to prepare for the next threshing operation. When the movable cylinder 24 is reduced, the engaging plate 35 moves downward in the large-diameter collar 37. The piece 32 is reduced by its own weight, and the engagement plate 35 abuts the boss 36 to push the boss 36, and each spiral wing piece 3
The interval 2 is surely shortened in accordance with the reduction of the moving cylinder 24.

And a starting end of a lateral discharge auger 19 is connected to an upper end side of the fried auger 18, and the fried auger 18 is connected to a fixed cylinder 23 provided at a vertical position on the fuselage side. Since this is a combine grain discharging device constituted by a movable cylinder 24 provided to be able to expand and contract with respect to the cylinder 23, the tank position of the light truck is located considerably above the body and the discharge auger 19 Even if it does not reach even if it is rotated upward about the base, the fixed cylinder 2 of the auger for frying 18
Since the moving cylinder 24 is extended and raised with respect to 3, the height of the distal end of the discharge auger 19 is increased, so that the discharge operation can be performed.
