According to this configuration, the number of outer struts on the outside is greater than the number of inner struts on the outside where the change in weight due to rolling of the fuselage is greater than on the inside, so the required strength is reduced with a small number as a whole. Easy to configure the tank support.
In addition, the number of inner struts is smaller than that of the outer struts, so that it is possible to reduce the cost by reducing the components of the tank support, and the inner struts on the inside where various devices are likely to be complicated. By reducing the number, there is an advantage that it is easy to easily install and maintain various placement devices and devices.

In the present invention, it is preferable that the tank support is supported by the threshing device at a portion on the threshing device side.

In the present invention, the tank support base is an outer strut positioned on the side farther from the threshing device, an inner strut positioned closer to the threshing device than the outer strut, and these It is preferable that an upper frame supported by at least one of the outer support column and the inner support column is provided.

According to this configuration, the tank support is configured by including the outer support, the inner support, and the upper frame, so that the space below the Glen tank supported by the tank support is disposed in the other device. There is an advantage that it can be easily secured as a space for use and maintenance.

In the present invention, it is preferable that the inner support column is connected to a support portion fixed on the vehicle body frame.

This configuration has an advantage that the strength of the tank support can be improved because the inner support column is connected to the support portion fixed on the vehicle body frame.

In the present invention, it is preferable that the upper frame of the tank support base includes an outer front and rear frame connecting the upper end side of the outer support column, and the outer front and rear frame supports one end side of the Glen tank.

According to this configuration, one end side of the Glen tank in the left-right direction can be stably supported via the outer front and rear frames of the upper frame, and the tank support base can be supported at a position on the outer side of the machine body as much as possible.
Therefore, there is an advantage that the Glen tank can be stably supported with a long span in the left-right direction.

In the present invention, the Glen tank is disposed over the entire width or almost the entire width in the left-right direction of the machine body, and the end opposite to the side supported by the outer front and rear frame is supported by the threshing device. It is preferable that

According to this configuration, the grain tank that is long in the left-right direction disposed over the entire width or almost the entire width in the left-right direction of the machine body is provided by the tank support base and the threshing device located on the opposite side of the tank support base. There is an advantage that it is easy to support stably.

According to this configuration, the end of the grain tank on the side of the grain discharge port can be rocked up and down around the rocking shaft center in the front-rear direction that is located laterally outward as much as possible.
Therefore, it is advantageous in that the grains stored in the Glen tank can be discharged from a position close to the laterally outer side of the machine body as much as possible by swinging up and down.

In the present invention, it is preferable that a dumping actuator for swinging the Glen tank up and down is supported on the inner support column.

According to this configuration, the actuator is positioned as far away as possible from the upper end side of the outer support column where the longitudinal axis serving as the swing fulcrum of the Glen tank exists to the side of the machine body in the left-right direction. Thus, it is advantageous in that the posture of the Glen tank can be easily changed.

In the present invention, the actuator lifts the end of the grain tank opposite to the grain outlet side by an extension operation, swings the grain tank to a discharge posture, and performs a contraction operation to The end of the grain tank opposite to the grain outlet side is lowered so that the grain tank is in the storage posture, and the upper end is the lower end in the storage posture. It is preferable to be equipped in a posture inclined toward the side farther from the end on the grain outlet side than the side.

According to this configuration, the actuator that is extended and contracted is in the storage posture of the Glen tank, and the upper end side is inclined to the side farther from the end portion on the grain outlet side than the lower end side. For this reason, when changing the posture of the Glen tank from the storage posture to the discharge posture, it acts so as to push up a portion far from the end on the grain discharge port side close to the pivot axis.
Therefore, there is an advantage that the Glen tank can be easily swung up and down with a relatively small driving force.

It is preferable that the position is fixed.

According to this configuration, the weight on the Glen tank side acts intensively on the inner strut that receives the reaction force of the actuator when the Glen tank is lifted to change the posture from the storage posture to the discharge posture. At this time, since the lower end portion of the inner column is supported by the main frame, it can be firmly supported even if a large weight on the side of the Glen tank acts.

In the present invention, it is preferable that the inner support column is erected in a state where the upper end portion is tilted toward the body side away from the outer support column than the lower end portion.

According to this configuration, since the inner support column is tilted toward the body side, the posture of the actuator to be supported by the inner support column is determined such that the upper end side connected to the glen tank is the lower end side connected to the inner support column. It can be equipped in a state tilted toward the aircraft side.
Therefore, when the posture of the Glen tank is changed by the expansion / contraction operation of the actuator, the actuator can be attached so that a place as far as possible from the end on the grain discharge port side close to the swing axis of the Glen tank can be pushed up. This has the advantage that the required driving force of the actuator can be reduced and a small size can be adopted.

According to this configuration, the inclination of the upper column part toward the inward side of the machine body is larger than a virtual line segment connecting the lower end of the lower column part and the upper end of the upper column part. Then, the vicinity of the intersection of the upper strut portion and the lower strut portion is closer to the swing axis of the Glen tank than one point existing at the same height on the imaginary line segment.
Therefore, when an actuator is provided near the intersection between the upper column part and the lower column part and near the upper end of the upper column part, the actuator is located at the same height as the intersection on the virtual line segment. The amount of expansion / contraction operation of the actuator can be made shorter than when the actuator is provided near one existing point and near the upper end of the upper support portion. That is, since the Glen tank undulates and swings around the swing axis, the upper end of the actuator connected to the lower surface side of the Glen tank also moves along an arc locus around the swing axis. At this time, the intersection between the upper column portion and the lower column portion where the lower end of the actuator is located is closer to the pivot axis than one point existing at the same height as the intersection point on the virtual line segment. Position.
For this reason, when the upper end of the actuator moves along the circular arc locus around the swing axis along with the extension operation of the actuator, the distance from the vicinity of the intersection of the upper column portion and the lower column portion to the upper end of the actuator is The distance from one point existing at the same height as the intersection on the imaginary line segment to the upper end of the actuator may be shorter. This also has the advantage that the amount of expansion and contraction of the actuator can be shortened.

In the present invention, it is preferable that the actuator is provided so that a lower end side is attached to the lower strut portion of the inner strut and is located outside the upper strut portion.

According to this configuration, the load on the side of the Glen tank acting on the actuator acts directly on the lower strut portion, not on the upper strut portion, and therefore acts on the upper strut portion intensively via the actuator. It is not necessary to apply the load on the grain tank side.
Therefore, there is an advantage that a difference in support strength between the upper support portion and the lower support portion can reduce the weight of the vehicle body and reduce the cost by reducing the weight of the upper support portion.

The third tension ring body 65 is pivotally supported by a support shaft 65 a provided on the mounting plate 77, and is not changed in position by the swinging operation of the operating arm 62, but is fixed on the mounting plate 77. It is what was done.
As shown in FIGS. 16 and 17, the second tension ring body 64 and the third tension ring body 65 include a shaft center p <b> 1 </ b> A of the relay output pulleys 55 b and 55 c that are drive rotating bodies and a fan input that is an input rotating body. The pulley 72 is arranged in a state of being distributed on both sides of an imaginary line segment L1A connecting the axis p2A of the support shaft 71 that is the rotation center of the pulley 72.

The forward rotation transmission belt 56 is wound around the relay output pulley 55b on the outer side of the machine body, the fan input pulley 72, and the first tension ring body 63 among the relay output pulleys 55b and 55c that are drive rotating bodies. Has been. The relay output pulley 55 b, the fan input pulley 72, and the first tension ring body 63 are all disposed so as to be in contact with the inner peripheral side of the normal rotation transmission belt 56.
Therefore, as shown in FIG. 16, when the operating arm 62 is operated to the “forward rotation” position indicated by the solid line, the swing plate 60 swings clockwise, and the forward drive belt 56 is tensioned. The first tension ring body 63 is moved. The position of the first tension ring body 63 is maintained so as to be in the forward transmission state even when the operation with respect to the operation arm 62 is released by the urging force of the coil spring 66 acting.
At this time, the arm portion 60 </ b> B of the swing plate 60 that supports the second tension ring body 64 swings (swings clockwise) to loosen the reverse transmission belt 57, and power is transmitted by the reverse transmission belt 57. Is in a state that is not performed.

The reverse transmission belt 57 includes a relay output pulley 55c, a fan input pulley 72, a second tension ring body 64, and a third tension ring body among the relay output pulleys 55b and 55c that are driving rotary bodies. It is wound over 65.
Among these, the relay output pulley 55c, the second tension ring body 64, and the third tension ring body 65 are in contact with the inner peripheral side of the reverse transmission belt 57, and the fan input pulley 72 is in contact with the outer peripheral side of the reverse transmission belt 57. Thus, the reverse transmission belt 57 is wound.
Accordingly, as shown in FIG. 17, when the operating arm 62 is operated to the “reverse rotation” position, the swing plate 60 swings counterclockwise against the biasing force of the coil spring 66 and the reverse transmission belt 57 is moved. The second tension ring body 64 is moved to the tension side. The reverse transmission belt 57 that is tensioned in this state is in the reverse transmission state.
At this time, the arm portion 60 </ b> A of the swinging plate 60 that supports the first tension ring body 63 swings (swings counterclockwise) to the side that loosens the normal transmission belt 56, and the normal transmission belt 56. The power transmission by is not performed.

As described above, the forward output power transmission mechanism is configured by including the relay output pulley 55b, the fan input pulley 72, the first tension ring body 63, and the normal transmission belt 56, and the relay output pulley 55c and the fan input pulley 72 are configured. The reverse tension power transmission mechanism includes the second tension ring body 64, the third tension ring body 65, and the reverse rotation transmission belt 57.
The forward / reverse selection mechanism 6 causes the forward drive belt 56 of the forward drive power transmission mechanism and the reverse drive belt 57 of the reverse drive power transmission mechanism to swing the swing plate 60 by operating the operation arm 62, It is constituted by a tension clutch capable of intermittently motive power by selectively selecting and tensioning or relaxing.
The swing operation of the swing plate 60 by the operation of the operation arm 62 is continued even when the operation force by the operation arm 62 is released by the biasing force of the coil spring 66 while the switching state to the forward rotation side is maintained. The operation to the reverse side is continued only while the swinging plate 60 is swung by the operation of the operation arm 62. When the operation by the operation arm 62 is released, the forward rotation is performed by the biasing force of the coil spring 66. The drive is automatically restored.

13 to 18 is a rod-shaped stopper guide integrally provided on the swing plate 60, and 68 is a plate-shaped stopper guide bent in an L shape. Reference numeral 77 b denotes a rod-shaped detachment prevention guide provided on the mounting plate 77. These are all for preventing the forward transmission belt 56 or the reverse transmission belt 57 from coming off.

For the forward transmission belt 56 and the reverse transmission belt 57 that are stretched across the pair of relay output pulleys 55b and 55c on the relay shaft 55 side and the fan input pulley 72 on the radiator cooling fan 70 side, A belt guide 69 for guiding the transmission belt 56 and the reverse transmission belt 57 is provided.
The belt guide 69 does not come into contact with the forward transmission belt 56 or the reverse transmission belt 57 in a state of being tensioned in the driving state with respect to the forward transmission belt 56 and the reverse transmission belt 57, and is not less than a predetermined amount. When slack occurs, it is configured to support it from below. By doing so, it is possible to avoid a state in which the slack reverse rotation transmission belt 57 or the normal rotation transmission belt 56 droops greatly and comes into contact with the forward rotation transmission belt 56 or the reverse rotation transmission belt 57 that is being driven. It is. As a result, it is possible to reduce the possibility that the slack reverse rotation transmission belt 57 or the normal rotation transmission belt 56 contacts the driving normal rotation transmission belt 56 or the reverse rotation transmission belt 57 and wears each other.

Specifically, as shown in FIGS. 16, 17, and 19, the belt guide 69 does not contact as indicated by the phantom line during the driving of the reverse transmission belt 57, and the forward transmission belt 56 is driven. When the reverse transmission belt 57 is not driven, the slack side and the tension side of the reverse transmission belt 57 are supported as shown by the solid line on the lower side when a predetermined amount of slack occurs. The 1st support part 69a and the 2nd support part 69b for carrying out are provided. On the reverse transmission belt 57 side, the side in contact with the fan input pulley 72 on the outer peripheral side of the reverse transmission belt 57 is the tension side, and the side in contact with the third tension ring body 65 on the inner peripheral side is the loose side.

Further, the belt guide 69 allows the slack side of the normal transmission belt 56 to be seen from below when a slack of a predetermined amount or more occurs on the slack side of the normal transmission belt 56 with respect to the normal transmission belt 56 side. A third support portion 69c is provided for support as indicated by the phantom line.
Since the first support portion 69a, the second support portion 69b, and the third support portion 69c are provided in this manner, either the forward transmission belt 56 or the reverse transmission belt 57 is loosened when switching between forward and reverse rotation. When this occurs, the slack forward rotation transmission belt 56 or the reverse rotation transmission belt 57 is prevented from drooping more than necessary.

As shown in FIGS. 16 and 17, an adjustment ring body 79 for removing slack is provided on the tension side of the forward transmission belt 56, as shown in FIGS. 16 and 17.
The adjustment wheel body 79 can be vertically changed with respect to the support member 78 erected from the front end portion of the rectangular tubular member 76 fixed to the fan mounting base 74 toward the upper frame 13C of the tank support base 13. It is attached.
The adjusting wheel 79 is positioned below the tension side of the normal transmission belt 56 so that when the normal transmission belt 56 is loosened, the drooping due to the slack of the normal transmission belt 56 can be limited. Just place it. The adjusting wheel 79 does not need to be in particular contact with the forward transmission belt 56 in a tension state, but when the longer forward transmission belt 56 is used, or when the forward transmission belt 56 is extended. In the case of loosening, the position for bringing the forward transmission belt 56 into a tension state may be adjusted in order to remove the slack.

The relay shaft 55 is attached to the upper frame 13C of the tank support 13 in a suspended state via an attachment bracket 13D.
A pair of relay output pulleys 55b and 55c provided on the relay shaft 55 is provided with a detachment prevention guide 58 as shown in FIGS.
The detachment prevention guide 58 faces the outer periphery of the relay output pulleys 55b and 55c, and is provided along the outer periphery of the relay output pulleys 55b and 55c on the front side of the machine body in a side view. The shape of the anti-separation guide 58 in a side view is formed so as to be along substantially half of the outer circumference of the relay output pulleys 55b and 55c while refracting the plate material into a polygonal shape.

The polygonal locking guide 58 is bolted to the mounting bracket 13D via a pair of mounting pieces 58a, 58a provided on both sides of the corner of the upper end.
Further, as shown in FIG. 21, the upper end portion and the lower end portion of the polygonal locking guide 58 are connected by relay output pulleys 55b and 55c and a U-shaped bent bar 58b that bypasses the relay shaft 55. Therefore, the strength of the detachment prevention guide 58 is increased.

On the equipment mounting base 232, as shown in FIG. 36 and FIG. A valve unit 260 in which control valves for hydraulic equipment are integrated and a battery 261 are mounted.
The device mounting base 232 includes an end of the support member 212b that protrudes laterally outward of the right vertical frame 210A, and an attachment seat 212d provided on the upper surface side of the right vertical frame 210A. It is connected to.

Of the outer struts 230, the rear outer strut 230c located at the rearmost portion is formed of a linearly formed square pipe material, the lower end is welded and fixed to the mounting plate 236a, and the upper end is the outer front and rear of the upper frame 234 which will be described later. The frame 234A is fixed by welding at a position near the rear portion. Thereafter, the lower end of the outer support column 230c is connected and fixed to the upper side of the support member 212a formed to protrude laterally outward of the right vertical frame 210A via a mounting plate 236a.

Further, an attachment piece 236c for fixing the reserve tank 262 is attached to the front side of the rear outer support 230c toward the inward side of the machine body. Accordingly, the radiator 270 can be installed on the rear side of the tank support 203 and the reserve tank 262 can be installed on the front side.

The inner column 231 will be described.
The inner strut 231 is composed of a single pillar member that is located closer to the center outer strut 230 in the front-rear direction and closer to the threshing device 204 than the outer strut 230.
As described above, the lower end of the inner column 231 is fixed to the equipment mounting base 232 by welding, and the upper end is fixed to the inner front and rear frames 234B of the upper frame 234 by welding. As shown in FIGS. 35 and 39, the lower end of the inner column 231 is a right side of the body frame 201, which is a main frame 210 located on the inward side of the body in the left-right direction of the body. Is fixed to the upper side of the vertical frame 210A.
As a result, the weight when lifting the Glen tank 205 acting intensively on the inner support 231 is configured to be received by the vertical frame 210A.

As shown in FIGS. 35, 37, and 39, the inner column 231 is formed by a combination of a thick rectangular tube-shaped lower column part 231A and a rectangular column-shaped upper column part 231B that is thinner than the lower column part 231A. Has been.
As shown in FIG. 35 to FIG. 37 and FIG. 39, the upper support portion 231B is in surface contact with the lower support portion 231A and on the rear side surface of the lower support portion 231A. Are integrated by welding.
The inner column 231 is erected in a tilted posture in which the upper end portion is directed toward the body side away from the outer column 230 than the lower end portion. Then, the angle at which the upper thin upper column part 231B is inclined with respect to the plane perpendicular to the body frame 201 is larger than the angle at which the lower thick lower column part 231A is inclined with respect to the plane perpendicular to the body frame 201. The tilt angles of the lower column part 231A and the upper column part 231B are made different so as to increase.

With this configuration, as shown in the conceptual diagram of FIG. 42, the amount of expansion / contraction of the dump cylinder 206 when the Glen tank 205 is tilted by a predetermined angle can be reduced.
For example, as shown in FIG. 42, the inner portion formed between the lower end point AB (fixed point to the vehicle body frame 201) of the lower column portion 231A and the upper end point BB of the upper column portion 231B is formed in a straight line. Between the support 231 and the lower end point AB of the lower support post portion 231A and the upper end point BB of the upper support post portion 231B, the intermediate point C1B is bent toward the side approaching the vertical line YB passing through the lower end point AB. Consider the inner strut 231 having the above shape, and compare it.
Both the linearly formed inner strut 231 and the bent inner strut 231 are inclined postures in which the upper end side is away from the outer strut 230 toward the inward side of the machine body rather than the lower end side. For this reason, when the dump cylinder 206 is disposed along the inner column 231, the side farther from the rocking axis z <b> 2 </ b> B of the Glen tank 205 is compared with the structure in which the inner column 231 is merely standing in the vertical direction. Both of them are useful in that they can be supported and pushed up and the driving force for lifting and driving the Glen tank 205 can be reduced.

In the inner strut 231 having a bent shape, a dump cylinder 206 having a predetermined length is provided between the upper end point BB and the intermediate point C1B. In the inner strut 231 formed in a straight line, the upper end point BB and the intermediate point C2B are It is assumed that the dump cylinder 206 having the same length is provided between the two.
