It is possible to perform stable threshing and selection processing while keeping the angle of the dust guide plates 60, 60 ', 60 "constant by controlling the traveling so as to keep the amount of dust close to the reference value.

Another Embodiment 3 Next, another embodiment 3 shown in FIGS. 13 and 14 will be described. First, the grain discharge cylinder 70 has a grain discharge port at its tip, has a base connected to an upper portion of a fried grain cylinder 71 so as to be vertically rotatable, and is configured to be vertically rotatable by a telescopic cylinder-72. There is. Further, the fried grain cylinder 71 includes a lower cylinder 71a and an upper cylinder 7.

The guide lights 76 and 76 'are attached to both the left and right sides of the tip end portion of the grain discharge cylinder 70 so that the turning direction side lights up prior to the turning operation. That is, when the storage switch in the cockpit is operated, the grain discharge cylinder 70 detects the position of the potentiometer 77 mounted on the swivel motor 73 and selects the direction close to the storage position to swivel. However, at that time, prior to turning, the guide lights 76, 76 '
The one on the turning direction side is lit up.

With the above configuration, the grain discharge cylinder 70
The operator within the turning locus of the turning direction can know the turning direction before the turning operation and can retreat, so that there is an advantage that the operation can be performed very safely.

Other Embodiment 4 Another embodiment 4 will be described with reference to FIGS. 15 to 20. The grain discharge cylinder 80 is connected to the upper part of the fried food cylinder so that the base can be freely turned up and down and swung like a known configuration, and the grain discharge port 81 is opened at the tip. Are configured. The grain discharge cylinder 80 is configured such that a discharge spiral is axially mounted inside and the grain sent from the fried grain cylinder on the base side can be conveyed and discharged from the grain discharge port 81 to the outside.

The lid 82 is pivotally attached to the outside so as to be openable and closable so as to close the grain discharge port 81, and the structure shown in FIGS. 16 and 17 is constructed by tensioning and tightening with a torque spring.
The configuration shown in FIG. 19 is attached to the operating rod 83. Therefore, first, the configuration example shown in FIG. 16 and FIG. 17 will be described.
One end of the connecting rod 84 is rotated by an auger receiving member 85, and normally, an operating link 87 is pulled by a spring 86.
The other side is connected to a pressing arm 88 pivotally attached to the outside of the lid 82. Therefore, when the grain discharge cylinder 80 is housed in and placed on the auger receiver 85, the pressing arm 88 is actuated against the spring 86 from the operation link 87 via the connecting rod 84. As shown in FIG. 17, the lid 82 is pressed from the outside.

In addition, the configuration example of FIG. 18 and FIG.
The operating rod 83 connecting the two is connected to the connecting rod 84. With the above configuration, the lid 82 forcibly tightens the grain discharge port 81 (see FIGS. 17 and 19) when the grain discharge cylinder 80 is stored in the auger receiver 85. Moreover, there is an advantage that there is no danger of inserting a hand or the like into the grain discharge cylinder 80, the safety is extremely high, and the grain remaining in the cylinder does not drop too much.

The configuration example shown in FIG. 20 is an example in which the lid 82 for closing the grain discharge port 81 is provided with a clogging sensor-89. With this configuration, the clogging sensor-89 detects the grain pressure when the pad is full and the lid 82 is pushed up and closed when the grain discharge port 81 is packed with the paddy bag. It has the feature that it can notify the full state.

Next, the operation will be described. First, when the work is started, the grains that have been threshed by the threshing device 3 are transported to the grain tank 4 by the first fried device 8 and supplied, and the grains are sequentially stored. In this way, when the threshing work proceeds, the grain tank 4 stores the grains processed in association with the threshing work and reaches a certain amount, and based on the detection of the full sensor installed inside the tank. An alarm is issued and the work begins to discharge grain.

First, the chassis 2 is moved to the edge of the road to approach the truck waiting on the farm road. Next, the grain discharge cylinder 1
3 moves by using the operating motor 16 and the telescopic cylinder-18 so that the grain discharge port 14 at the tip thereof faces the tank of the truck at the edge of the ridge to prepare for grain discharge work. Then, when the operator appropriately operates, the discharge spiral 10
Is transmitted from the prime mover 23 in the order of the direction changing gear box 24, the drive shaft 25, the drive gear 27, and the vertical gear 22, and is rotated to start the grain unloading operation. And fried helix 1
2 and the discharge spiral 15 in the grain discharge cylinder 13 are sequentially transmitted from the transmission shaft 10a and rotated, and the grains stored in the grain tank 4 can be carried out to the tank of the truck described above.

Next, an operation of rotating the grain tank 3 to the outside of the traveling vehicle body 1 in order to perform maintenance between the threshing device 2 and the grain tank 3 will be described. First,
The operator is the operator of the Glen tank 4 in FIG.
When the operation lever 34 is operated in the clockwise direction prior to the punting operation, the operation interlocking rod 33 rotates in the same direction. Then, the rotary locking rod 29 is interlocked with the lower connecting rod 35, the locking portion 28 at the tip portion pivots upward to open the fixed locking tool 6a, and the upper rotary locking rod 31. The base portion is pulled downward by the upper connecting rod 36, and the locking portion 30 at the tip pivots upward with the pivot portion as a fulcrum to open the fixed locking tool 6b.

As described above, the Glen tank 4 has two upper and lower parts.
The upper locking device 5b and the lower locking device 5a are interlocked with each other and simultaneously released from the locked state to be in a free state, and moved toward the outside of the chassis 2 about the rotation fulcrum a. At this time, the vertical gear 22 is rotated integrally with the Glen tank 4 and disengages from the drive gear 27 so that the meshing is released and the vertical gear 22 can move.

As described above, when the Glen tank 4 is rotated to the outer position of the chassis 2 as shown in FIGS. 2 to 4, a space portion is formed on the side portion of the threshing device 3 and is arranged at that portion. It is possible to easily perform maintenance of the transmission device that is used. Next, when returning to the normal working position, the Glen tank 4 may be rotated in the opposite direction of the open operation, and returns to the range of the width of the chassis 2 around the rotation fulcrum a. At that time, the guide guide plate 38 can be easily returned to the original position by the fixed locking tool 6b being guided and guided in the guide concave portion at the tip thereof.

The lower locking device 5a and the upper locking device 5b can be operated from the operation interlocking rod 33 to the lower connecting rod 35 by operating the operation lever 34 in the opposite side (counterclockwise direction) when the lock is released. And the upper connecting rod 36 simultaneously push downward and upward,
The upper and lower two rotation locking rods 29 and 31 are rotated. Then, the locking portions 28 and 30 at the tips rotate downward with the pivotally-attached portion as a fulcrum and engage with the fixed locking tools 6a and 6b, respectively, and are locked.

The vertical gear 22 is located above the drive gear 27 and returns to the meshing state in which it can be transmitted. As described above, since the Glen tank 4 is firmly engaged with the chassis 2 side in two places at the upper and lower sides, it is integrated with the chassis 2 even when traveling in a rough field scene. Although it may vibrate, it does not vibrate significantly in a separate body.

[0037]

As described above, according to the present invention, the threshing device 3 for threshing the supplied grain culms is mounted on the chassis 2 equipped with the traveling device 1, and the threshing device 3 side is provided. On the other hand, a grain tank 4 for accommodating and storing threshed grains is mounted and provided, and the grain tank 4 has either one of the front side and the rear side with respect to the forward direction of the chassis 2 on the chassis 2 side. And the other side is separated from the threshing device 3 so that the other side can be rotated to the outside of the chassis 2.
A lower locking device 5a and an upper locking device 5b are provided on the outer side of the Glen tank 4 so that they can be operated in association with each other.
The lower locking device 5a is attached to the fixed locking tool 6a on the chassis 2.
Further, the upper locking device 5b is a fixed locking tool 6 on the threshing device 3 side.
Since the gren tank is configured so that it can be freely engaged and disengaged with each other, the Glen tank can very easily and simultaneously perform the related operations of the two upper and lower locking devices at the same time when the threshing device is maintained. Since it is possible to perform the engagement and disengagement operation, it is possible to perform the opening and closing operation easily.

In addition to this, according to the present invention, the Glen tank can be securely locked to the chassis side by using the two upper and lower locking devices, so that the Glen tank is not affected by the vibration generated during traveling. However, even if it vibrates integrally with the chassis, there is almost no vibration in a separate body, and it has a remarkable effect that stable traveling and work are possible.
