7, a plurality of rollers 23 are provided to facilitate movement of the movable auger cylinder 17 with respect to the fixed auger cylinder 9. Further, it is preferable to provide a seal member 24 on the entire circumference between the fixed auger cylinder 9 and the movable auger cylinder 17 because scattering of grains can be prevented. In this case, if the moving auger cylinder 17 is configured to have a larger diameter than the fixed auger cylinder 9, the movement of the grains becomes better and clogging can be prevented, which is preferable. Further, since the telescopic operation shaft member 16 is provided on the outer periphery of the movable auger cylinder 17, the movement of the telescopic operation shaft member 16 and the fixed auger cylinder 9 do not interfere with each other, resulting in a reasonable configuration. Further, at least the moving auger cylinder 17 of the fixed auger cylinder 9 and the moving auger cylinder 17 is formed by a tubular member having a seam 30, the seam 30 is provided inside, and the seam 30 is provided on the outer periphery of the fixed auger cylinder 9. Guide member 32 having fitting groove 31 to be fitted
Is provided. Note that a plurality of guide members 32 may be provided at predetermined intervals in the circumferential direction. The fixed auger cylinder 9 and the movable auger cylinder 17 are provided with telescopic spirals 33. The telescopic spiral 33 includes a fixed half cylinder member 34 and a movable half cylinder member 35, each of which is formed by dividing a cylindrical member into approximately half in parallel with the generatrix direction.
Are provided so as to face each other, and a fixed half-spiral blade 36 and a movable half-spiral blade 37 are provided on the outer periphery of the fixed half cylinder member 34 and the movable half cylinder member 35, respectively. The movable half cylinder member 35 is configured to expand and contract with respect to the fixed half cylinder member 34 in accordance with the expansion and contraction of the movable auger cylinder 17 with respect to the cylinder 9.

That is, when it is most reduced, the fixed-side half spiral blade 36 and the moving-side half spiral blade 37 constitute a continuous spiral blade over the entire circumference. They will be lined up at intervals. One end of a fixed inner guide member 38 is fixed to the inner surface of the fixed half cylinder member 34, and one end of a movable inner guide member 39 is fixed to the inner surface of the movable half cylinder member 35. The other ends of the fixed inner guide member 38 and the movable inner guide member 39 are formed on separated surfaces so as not to come into contact with the inner surfaces of the fixed half cylinder member 34 and the movable half cylinder member 35, respectively. Also,
It is preferable that a plurality of the fixed half cylinder members 34 and the movable half cylinder member 35 are provided side by side in the longitudinal direction. The fixed inner guide member 38 and the movable inner guide member 39 are formed with fixed-side different-diameter insertion holes 40 and moving-side different-diameter insertion holes 41 having different diameters, respectively. Insertion hole 41
, A transmission shaft member 42 having the same outer peripheral surface is inserted. In this case, the fixed-side different-diameter insertion hole 40, the moving-side different-diameter insertion hole 41, and the transmission shaft member 42 may have a quadrangular or pentagonal polygonal shape or a so-called oval shape. It is configured to transmit the rotation by sliding with respect to the hole 40 and the moving-side different-diameter insertion hole 41 but not rotating.

The vertical spiral 5a in the vertical fryer 5
Bevel gears on fixed auger spiral 11 (not shown)
The rotation of the fixed auger spiral 11 is transmitted to the fixed half cylinder member 34, and the rotation of the fixed half cylinder member 34 is transmitted to the fixed inner guide member 38.
The rotation of the fixed inner guide member 38 is transmitted to the transmission shaft member 42, the rotation of the transmission shaft member 42 is transmitted to the movable inner guide member 39, and the rotation of the movable inner guide member 39 is transmitted to the movable half cylinder member 35. Thereby, the moving side half spiral blade 37 is rotated. Accordingly, when the base side of the fixed half cylinder member 34 is axially mounted on the intermediate metal member 10, and the distal end side of the movable half cylinder member 35 is axially mounted on the distal end bearing member 50 of the movable auger cylinder 17, it is possible to expand and contract. The spiral 33 has a configuration in which the start end side and the end side are supported by the intermediate metal member 10 and the front end side bearing member 50 and rotate. In the embodiment, a fixed-side cylindrical member 43 is provided on the base side of the fixed-side half-cylindrical member 34, and a fitting hole 44 is provided on the base of the fixed-side cylindrical member 43.
The front end (end) of the fitting transmission shaft 14 of the middle bearing portion 13 of the intermediate metal member 10 is fitted to the middle bearing member 13. Fitting transmission shaft 14
Is attached to the middle bearing portion 13 of the intermediate metal member 10 so as to be rotatable only. The fixed auger spiral 11 and the fixed-side tubular member 43 are mounted on the shaft, and the fixed auger spiral 11 and the fixed-side half tubular member 34 (fixed-side). The rotation is transmitted by connecting to the cylindrical member 43). Further, a fixed-side full-circle spiral blade 45 is provided on the outer periphery of the fixed-side cylindrical member 43, whereby the front and rear portions of the intermediate metal member 10 are combined with the fixed auger spiral 11 to form a full-round spiral blade. Configure and secure the transfer force. In addition, a movable side tubular member 46 is provided at the tip end side of the movable side half tubular member 35,
A moving-side full-circle spiral blade 47 is provided on the outer periphery of the moving-side cylindrical member 46 to secure a conveying force near the discharge port 48 of the lateral discharge auger 6. Therefore, the start and end sides of the telescopic spirals 33 other than the fixed half spiral blades 36 and the movable half spiral blades 37 are configured as a full spiral (continuous spiral). In this case, if the moving-side full-circle spiral blade 47 is formed shorter than the fixed-side full-circle spiral blade 45, not only can the entirety be reduced in weight, but also the leading end of the lateral discharge auger 6 becomes lighter and the weight balance becomes better. Is preferred.

A shaft portion 49 is formed at the distal end side of the movable side tubular member 46, and the shaft portion 49 is protruded from an opening 52 formed in the movable auger barrel 17 so that the distal end side bearing member 50 can rotate only. Attach the shaft. In this case, the shaft portion 49 may be formed so that the transmission shaft member 42 protrudes from the moving-side cylindrical member 46 and is coaxial with a round shaft. Further, the distal end side bearing member 50 may be provided in the moving auger cylinder 17, and in this case,
It is preferable to provide a conical portion 53 that becomes thinner toward the distal end on the moving-side cylindrical member 46 side of the shaft portion 49, because attachment to the distal-end-side bearing member 50 is further facilitated. Also, by mounting the shaft portion 49 on the distal-end-side bearing member 50 so as to be rotatable only, the extending movable auger cylinder 17 pulls the movable-side tubular member 46 to extend the telescopic spiral 33, and conversely, the movable auger cylinder 33 is extended. When the cylinder 17 is contracted, the movable side cylinder member 46 is pushed in to contract the telescopic spiral 33. In this case, the transmission shaft member 42 is located between the fixed inner guide member 38 and the movable inner guide member 39, and the transmission shaft member 42 is only slidable with the fixed inner guide member 38 and the movable inner guide member 39. Then, the expansion and contraction of the expansion and contraction spiral 33 is guided, and the rotation is transmitted.
Even if it is fixed to one of the fixed half cylinder member 34 and the movable half cylinder member 35, the embodiment can be implemented, and the mounting configuration including the fixing of the transmission shaft member 42 is arbitrary. In the embodiment, the distal end of the transmission shaft member 42 is fixed to the distal end side of the moving-side cylindrical member 46, and the base of the transmission shaft member 42 is reduced when the fixed-side cylindrical member 4 is reduced.
3 so that the transmission shaft member 42 slides with respect to the fixed inner guide member 38 and does not slide with respect to the movable inner guide member 39. A plurality of fixed inner guide members 38 and movable inner guide members 39 are provided at predetermined intervals, and the movable inner guide member 39 is responsible for the rotation transmitting action.
We also expect the function of guiding expansion and contraction.

The transmission shaft member 42 has a hollow cylindrical shape inside, and the balance piece 5 is provided on the inner surface on the side where the fixed half spiral blade 36 and the movable half spiral blade 37 are not provided.
4 is provided to make the rotation of the telescopic spiral 33 smooth. Also,
A shielding member 55 is provided at the boundary between the fixed-side half tubular member 34 and the fixed-side tubular member 43 and at the boundary between the movable-side half tubular member 35 and the movable-side tubular member 46 to prevent the entry of grains. It is possible and suitable. Then, the fixed half spiral wing 36
The moving-side half spiral blade 37 has an entry side 56 (upper side in the transport direction) close to an angle perpendicular to the axial direction to form an entry surface 58a, and a release side 57 (lower side in the transport direction) has a generatrix. The feed surface portion 58b is formed at an angle close to the direction (FIG. 28). That is, in the spiral blade, the conveying force is proportional to the contact resistance, and if the conveying force is strong, the contact resistance is increased, and the grains may come off. This conveying force is proportional to the contact area,
In the direction perpendicular to the axial direction, the transport action is zero or weak,
When the wing shape is parallel to the generatrix direction, the conveying force becomes stronger (the wing shape simply has no conveying force in the wing shape parallel to the generatrix direction, but needs to be an inclined surface, but is expressed as parallel for the sake of comparison with an orthogonal surface). Therefore, if the starting end side (upper side) in the transport direction is formed on the entry surface portion 58a and formed on the end side feed surface portion 58b, the impact at the time of contact with the grain by the entry surface portion 58a is reduced, and the subsequent feed surface portion is formed. The transfer is ensured by 58b. FIG. 29 shows an embodiment in which the feed surface 58a is slightly enlarged.

FIG. 31 shows another embodiment, in which a starting end side feed surface 58c is formed at the start end of the entry surface 58a. That is, since the fixed-side half spiral blade 36 and the moving-side half spiral blade 37 are provided with one half spiral blade at an interval of one, the upper half side of the half-spiral blade is located at the start end side of the entry surface 58a. In this case, a starting end side feed surface portion 58c for taking over the grain conveyed from the feed surface portion 58b of the half spiral wing is provided to smoothly convey. The fixed-side half spiral blade 36 and the moving-side half spiral blade 37 are formed such that the corner of the entry side 56 is formed into an arc portion 58d having an arc shape, and the corner of the escape side 57 is formed as an isolated end surface. Thus, the fixed half spiral wings 36 and the movable half spiral wings 37 may be configured such that the fixed-side full-circle spiral wings 45 and the moving-side full spiral wings 47 have different intervals (pitch). . In this case, if the interval between the fixed-side half spiral blade 36 and the moving-side half spiral blade 37 is made short (narrow), the rotational load can be reduced.
The fixed half spiral blade 36 and the movable half spiral blade 3
7 is long (wide), the fixed-side full-circle spiral blade 45
There is no problem because they are conveyed by the spiral wings 47 on the moving side and the entire length thereof, and it is preferable that the distance is made longer (wider) so that the weight can be reduced and the sliding amount can be increased. .

The fixed half spiral wings 36 and the movable half spiral wings 37 are formed at the same interval, and when they are expanded and contracted, they form a continuous spiral (full circumference spiral wing). In this case, when the driving amount of the driving member 18 is detected by a detecting member 60 such as a potentiometer and is expanded and contracted, the moving half spiral blade 37 and the fixed half spiral blade 36
Is preferably configured to stop in a continuous state, so that the conveyance is smooth. Further, when reducing the moving-side half spiral blade 37, one interval (one pitch) of the moving-side half spiral blade 37 is reduced to one unit so as to form a continuous spiral (full-circle spiral blade). I do. in this case,
When the extension / retraction operation of the lateral discharge auger 6 is performed and the fixed half spiral blade 36 and the movable half spiral blade 37 of the expansion / contraction spiral 33 are shifted and stopped, when the extension operation is performed, the extension is performed to correct the deviation.
In the case of a reduction operation, the image is reduced to correct the deviation. Further, it is preferable that the end of the fixed-side half spiral blade 36 and the start of the movable-side half spiral blade 37 be in a continuous state when extended to the maximum, so that the transport becomes smooth and suitable. Then
In the expansion and contraction operation of the lateral discharge auger 6, normally, when the switch is operated, the operation is automatically stopped.
6 and the moving-side half spiral blade 37 are shifted and stopped,
It is preferable to operate (drive) as it is because the operability is improved.

[0015]

Next, the operation will be described. Run the fuselage and cut the mower 3
The culm in the field is cut off by threshing and threshing by the threshing device 2, the threshed grains are stored in the Glen tank 4, and the grain tank 4
Is full, the grain is fried by the vertical fryer 5, and the fried grains are discharged to the tank of the truck near the field by the horizontal discharge auger 6. Thus, since the horizontal discharge auger 6 is formed by dividing the fixed auger 7 connected to the vertical fryer 5 and the movable auger 8 attached to the fixed auger 7 to extend and contract, the drive member 18 is formed. When operated by a motor or the like, the expansion and contraction operation shaft member 16 is extended by the operation of the driving member 18, and the expansion and contraction operation shaft member 16 extends the moving auger 8 with respect to the fixed auger 7, and the tip of the lateral discharge auger 6 is It is easier to align with the tank. Also,
When the discharge operation is completed, the lateral discharge auger 6 is stored in a reduced size, and the next operation is resumed, so that the operation is not hindered and the workability is improved. In this case, the telescopic operating shaft member 1
6 and the drive member 18, the telescopic operation shaft member 16 is formed in the rack groove 19, and the drive member 18 is formed in the pinion gear 20 and meshed with each other. Even in the case of the moving auger 8, it is expanded and contracted smoothly and reliably.

The fixed auger cylinder 9 and the movable auger cylinder 17
Are configured to be superimposed and expanded by different diameters, and a plurality of rollers 23 are provided between the fixed auger cylinder 9 and the moving auger cylinder 17.
The expansion and contraction movement of the moving auger cylinder 17 with respect to Further, since the seal member 24 is provided on the entire circumference between the fixed auger cylinder 9 and the movable auger cylinder 17 so as to close the gap, the scattering of grains from the gap is prevented. Thus, one of the fixed auger cylinder 9 and the movable auger cylinder 17 is made thicker to be overlapped with each other, but the movable auger cylinder 1 is larger than the fixed auger cylinder 9.
Since the diameter of 7 is larger, the volume of the transfer channel is larger on the lower side, so that clogging is prevented. In addition, with this configuration, the arrangement of the telescopic operation shaft member 16 is also facilitated, and the movement of the telescopic operation shaft member 16 does not interfere with the fixed auger cylinder 9, resulting in a rational configuration. Further, at least the moving auger cylinder 17 of the fixed auger cylinder 9 and the moving auger cylinder 17 is formed by a tubular member having a seam 30 and the seam 30 is provided so as to be bent inward.
The cost can be reduced by forming the cylindrical member having the shape. Since a guide member 32 having a fitting groove 31 into which the joint 30 is fitted is provided on the outer periphery of the fixed auger cylinder 9, expansion and contraction of the movable auger cylinder 17 can be guided by using the joint 30. An anti-rotation effect can also be expected, and this point is also a reasonable configuration.

Thus, the fixed auger cylinder 9 and the movable auger cylinder 17 are provided with a telescopic spiral 33. The telescopic spiral 33 is composed of a fixed half cylinder part 34 obtained by dividing the cylindrical member into approximately half in parallel with the generatrix direction. Since the fixed-side half spiral blade 36 and the movable-side half spiral blade 37 are provided on the outer periphery of the movable-side half-cylindrical member 35 in half, respectively, the fixed-side half spiral blade 36 and the movable-side half The spiral wings of each half of the spiral wings 37 are arranged at predetermined intervals. Therefore, the difficulty of manufacturing individual parts is not high, and the simple structure and the expansion and contraction spiral 3
3 can be constituted, cost can be reduced, and weight can be reduced. That is,
In the conventional configuration, both the spiral wing and the center member for attaching the spiral wing are provided and expanded and contracted, so that the weight and the cost are doubled, but the fixed half cylinder member 34 and the movable half cylinder member 35 are one in one. As one continuous spiral is constituted by the fixed half spiral wing 36 and the movable half spiral wing 37, the number of components is not increased while the expansion and contraction spiral 33 is configured to expand and contract. , Do not increase the cost. Thus, one end surface of the fixed inner guide member 38 is fixed to the inner surface side of the fixed half cylinder member 34, and one end surface of the movable inner guide member 39 is fixed to the inner surface side of the movable half cylinder member 35. In the fixed inner guide member 38 and the movable inner guide member 39, a fixed side different diameter insertion hole 40 and a moving side different diameter insertion hole 41 are formed, and the fixed side different diameter insertion hole 40 and the movement side different diameter insertion hole 41 are formed. Since the transmission shaft member 42 is inserted, the movable half cylinder member 35 expands and contracts along with the transmission shaft member 42, and the expansion and contraction of the expansion and contraction spiral 33 is performed smoothly.

The fixed-side different-diameter insertion hole 40, the moving-side different-diameter insertion hole 41, and the transmission shaft member 42 are formed in a quadrangular or pentagonal polygonal shape or a so-called oval-shaped non-circular non-circular shape. When the fixed half cylinder member 34 is rotated, the transmission shaft member 42 is thereby rotated, and the rotation of the transmission shaft member 42 causes the movable half cylinder member 35 to rotate. Therefore,
The transmission shaft member 42 guides the expansion and contraction of the telescopic spiral 33 and also transmits the rotation. Further, the cost can be reduced as compared with the key or spline configuration, and the assembly becomes easy. The fixed half cylinder member 34 may transmit the rotation of the vertical spiral 5 a in the vertical fryer 5 via the fixed auger spiral 11 of the fixed auger 7. Thus, the base side of the fixed side half cylinder member 34 of the telescopic spiral 33 is mounted on the intermediate metal member 10 at the middle part of the fixed auger cylinder 9, and the tip side of the movable half cylinder member 35 is the movable auger cylinder 17. , The base and the tip of the telescopic spiral 33 are supported by being mounted on the shaft, and rotate smoothly. In this case, in the embodiment, the fitting transmission shaft 14 is rotatably mounted on the middle bearing portion 13 of the intermediate metal member 10, and the terminal side (front end side) of the fitting transmission shaft 14 is fixed to the fixed half cylinder member 34. Since the fitting end 44 of the fitting transmission shaft 14 is fitted into the fitting hole 12 of the fixed auger spiral 11, The intermediate metal member 10 not only functions as a bearing for mounting the fixed auger spiral 11 and the fixed-side tubular member 43 on a shaft, but also the fixed auger spiral 11 and the fixed-side half-split tubular member 34 (the fixed-side tubular member) by the fitting transmission shaft 14. The member 43) is connected to transmit rotation.

Since the fixed-side full-circle spiral blade 45 is provided on the outer periphery of the fixed-side cylindrical member 43, the intermediate metal member 10 is formed by the fixed-side full-round spiral blade 45 and the fixed auger spiral 11.
The spiral blades of the entire circumference can be arranged at the front and rear sides of the intermediate metal member 10, thereby securing the conveying force between the front and rear of the intermediate metal member 10.
In addition, a moving-side tubular member 46 is provided at the distal end side of the moving-side half tubular member 35, and a moving-side full-circle spiral blade 47 is provided on the outer periphery of the moving-side tubular member 46. The conveyance force near the outlet discharge port 48 is secured. Therefore, the start and end sides of the telescopic spirals 33 other than the fixed half spiral blades 36 and the movable half spiral blades 37 are configured as a full-circle spiral (continuous spiral).
, While securing the transfer force. Thus, a shaft portion 49 is formed at the distal end side of the movable side tubular member 46 of the movable side half tubular member 35 of the telescopic spiral 33, and the shaft portion 49 is connected to the movable auger barrel 17.
Projecting from the opening 52 formed in the front end side bearing member 5
Since only the shaft is freely rotatable to zero, the telescopic spiral 33 can be inserted into the distal end side bearing member 50 from the opening 52, and mounting becomes very easy, and maintenance becomes easy. . That is, it is not easy to simply provide the distal end side bearing member 50 inside the moving auger cylinder 17 and insert the telescopic spiral 33 from the base side of the moving auger cylinder 17 to attach the distal end, but the opening 52 is provided. This facilitates the mounting. In addition, since the conical portion 53 that becomes thinner toward the tip is provided on the moving-side cylindrical member 46 side of the shaft portion 49,
The attachment to the distal end side bearing member 50 is further facilitated.

Thus, the shaft 49 is connected to the front-end bearing member 50.
Since the shaft of the movable half cylinder member 35 is attached to the movable auger cylinder 17 only by rotatably mounting the shaft on the movable auger cylinder 17,
When the movable auger cylinder 17 extends with respect to the fixed auger cylinder 9, the movable side cylinder member 46 is pulled by the movable auger cylinder 17 to extend the telescopic spiral 33, and conversely, when the movable auger cylinder 17 is reduced, the telescopic spiral 33 is reduced. Let it. In this case, the transmission shaft member 42 guides the expansion and contraction of the fixed half cylinder member 34 and the movable half cylinder member 35, and is expected to have an effect of transmitting rotation. The transmission shaft member 42 may be located between the fixed inner guide member 38 and the movable inner guide member 39, and the transmission shaft member 42, the fixed inner guide member 38, and the movable inner guide member 39 may be in a slidable relationship. Note that the transmission shaft member 42 can be implemented even if it is fixed to either the fixed half cylinder member 34 or the movable half cylinder member 35. Optional. In the embodiment, the distal end of the transmission shaft member 42 is fixed to the distal end side of the moving-side cylindrical member 46, and the base of the transmission shaft member 42 is configured to be housed in the fixed-side cylindrical member 43 when reduced.
Since the fixed side tubular member 43 is also used as a storage portion of the transmission shaft member 42, space can be effectively used, and the whole can be reduced in size as compared with the expansion and contraction ratio.

When a plurality of fixed inner guide members 38 and movable inner guide members 39 are provided at predetermined intervals, smooth and reliable rotation can be transmitted, and smooth and reliable expansion and contraction guide is provided. That is,
If a minimum number is provided, guidance and rotation transmission can be achieved, strength can be ensured, concentricity can be easily ensured, and manufacturing and assembly accuracy is improved. Thus, the transmission shaft member 42 is formed in the shape of a hollow rectangular cylinder, and the balance piece 54 is provided on each of the inner surfaces on the side where the fixed half spiral blade 36 and the movable half spiral blade 37 are not extended. Therefore, the rotational balance is improved, and noise due to resonance can be prevented.
To make the rotation smooth. In this case, since the balance piece 54 is provided in the transmission shaft member 42, the balance piece 54 does not interfere with the expansion and contraction of the fixed half cylinder member 34 and the movable half cylinder member 35,
It will be a reasonable configuration. Further, a boundary portion between the fixed-side half tubular member 34 and the fixed-side tubular member 43 and the moving-side half tubular member 35
A shielding member 55 is provided at the boundary between the
Is provided, it is possible to prevent grains from entering the fixed half cylinder member 34 and the movable half cylinder member 35. The shielding member 55 includes a fixed half cylinder member 34 and a movable half cylinder member 35.
Are provided on the respective end surfaces, an opening preventing action for preventing the half-cylinder member from opening can also be expected, and the sheet can be transported reliably.

Thus, the fixed side half spiral blade 36 and the movable side half spiral blade 37 are formed such that the entry side 56 is formed at an approach surface 58a at an angle orthogonal to or close to the axial direction, and the exit side 57 is formed in the generatrix direction. Feed surface 58b inclined to an angle close to
, The entrance surface portion 58a is formed on the feed surface portion 58b.
Rotational resistance (shock) to the grain is further reduced to prevent the occurrence of slippage, and the slanting side 57 has a stronger inclination of the feed surface 58b than the entrance surface 58a, thereby increasing the conveying force. That is,
Because of the half-helix, the beginning always touches the grain,
This initial resistance or impact is reduced, and the terminal side secures feeding. Also, in the embodiment of FIG.
Since the starting end side feed surface portion 58c is also formed on the start end side of a, the grain conveyed from the feed surface portion 58b of the half spiral wing on the better side is taken over, so that the handing over becomes smooth. That is, the grain is not conveyed in a state where the entire inside of the moving auger cylinder 17 is filled, but is located at a depth of about half, and the fixed side half spiral blade 36 and the moving side half spiral blade 37 , While being conveyed to the lower side while being scooped up, the starting end side feed surface portion 58c
Has a small impact at the time of abutment because it takes over the grains scooped up by the feed surface portion 58b on the better side, and has an entry surface portion 58a next to the feed surface portion 58b on the starting end side to make the inclination substantially orthogonal. Therefore, the impact when the feed surface portion 58b on the end side comes into contact with the bottom grain in the moving auger cylinder 17 is reduced. In short, since the entry surface portion 58a is formed in a part of the spiral wing, the impact when coming into contact with the grain is reduced.

The fixed half spiral blade 36 and the movable half spiral blade 37 are formed such that the corner of the entry side 56 is formed into an arc-shaped portion 5 having an arc shape.
Since it is formed in 8d, the beginning end contacts the grain,
This initial resistance or impact is reduced. In addition, since the winding of the straw waste is prevented by the arc portion 58d and can be constituted only by this processing, an increase in cost can be suppressed. Also,
Since the corner of the escape side 57 is formed on the end face as it is cut off, the conveying force is secured because the area of the spiral blade is not reduced. The fixed-side half spiral blade 36 and the moving-side half spiral blade 37 may be configured such that the fixed-side full-round spiral blade 45 and the moving-side full-round spiral blade 47 have different intervals (pitch). If the distance between the fixed-side half spiral blade 36 and the moving-side half spiral blade 37 is short (narrow), the rotational load can be reduced. Even if the distance between the fixed half spiral blade 36 and the movable half spiral blade 37 is long (widened), the fixed half spiral blade 45 and the movable full spiral blade 47 convey the same, respectively. However, it is preferable that the distance be long (wide) to reduce the weight and to increase the slide amount. If the fixed half spiral blade 36 and the movable half spiral blade 37 are formed at the same interval, a continuous spiral (full-circle spiral blade) can be formed, which is preferable.

In this case, the amount of expansion and contraction of the moving auger 8 is detected by detecting the amount of driving of the driving member 18 by a detecting member 60 such as a potentiometer. Since the spiral blades 36 are stopped in a continuous state, the transportation is smooth, the wear resistance of the movable half spiral blades 37 and the fixed half spiral blades 36 is improved, and the durability is also improved. . That is, when the moving-side half spiral blade 37 is expanded and contracted, one interval (one pitch) of the moving-side half spiral blade 37 is expanded and contracted by one unit. Wing) to reduce the rotational load. In this case, the extension / retraction operation of the lateral discharge auger 6 is performed to
When the fixed half spiral blade 36 and the moving half spiral blade 37 of 3 are shifted and stopped, when the extension operation is performed, the displacement is corrected by correcting the displacement, and when the reduction operation is performed, the displacement is corrected by correcting the displacement. The sensation of the user and the actual expansion / contraction match, the operation feeling is improved, and the operability is improved. In addition, when extended to the maximum, the end of the fixed-side half spiral blade 36 and the beginning of the movable-side half spiral blade 37 are in a continuous state, so that the transport is smooth. Therefore, in the expansion and contraction operation of the lateral discharge auger 6, even when the fixed half spiral blade 36 and the movable half spiral blade 37 of the telescopic spiral 33 are shifted and stopped by giving priority to the operation, they are operated (driven) as they are. In addition, the positioning of the discharge port 48 can be reliably performed, and the operability is improved. That is, if the fixed half spiral blade 36 and the movable half spiral blade 37 can be operated only when they coincide with each other, the alignment adjustment range of the outlet 48 becomes narrower, and it becomes necessary to move the airframe. 4
8 to facilitate the alignment and improve the operability.

And the moving side half spiral blade 37 can form a continuous spiral. In the present invention, when the telescopic spiral 33 is stopped at an intermediate position between the half spiral wing and the half spiral wing in the telescopic operation, the telescopic spiral 33 is extended at the time of the extending operation and is reduced at the time of the reducing operation to the one unit position. Since the grain discharging device is adapted to match, when the fixed half spiral wing 36 and the moving half spiral wing 37 of the telescopic spiral 33 are shifted and stopped, in the case of the extension operation, it is stretched to correct the gap. In the case of a reduction operation, the displacement can be corrected by reducing the size, and the sense of the operator matches the actual expansion and contraction, so that the operation feeling is improved and the operability is improved. According to the present invention, the telescopic spiral 33 is a grain discharging device that stops the expansion and contraction so as to form a continuous spiral when the fixed half spiral blade 36 and the movable half spiral blade 37 overlap. From, when stretched,

In the present invention, the expansion and contraction of the moving auger 8 is a grain discharging device that is detected by a detection member 60 such as a potentiometer. The present invention relates to the moving side half spiral blade 37.
The expansion and contraction of the grain discharging device is such that the manual operation of stopping at the intermediate position of the expansion and contraction interval is prioritized to the automatic stop in which the fixed half spiral blade 36 and the moving half spiral blade 37 are continuously spiraled with each other. Therefore, it is possible to give priority to the positioning of the truck with respect to the tank, thereby improving operability and improving work efficiency.
