It is levitated over the entire length together with the front part by 1. On the contrary, when housing the support leg 1 and the hydraulic cylinder 2, etc., the hydraulic cylinder 2 is contracted in the opposite manner to the above, the rear portion of the crawler 14 is grounded, and then the crawler 14 is driven in the reverse direction. Is rotated upward from the standing position to be in the storage posture. At this time, the supporting leg 1
Since the hydraulic cylinder 2 and the hydraulic cylinder 2 are interlocked with each other in the storage direction, the hydraulic cylinder 2 also takes the storage posture as the support leg 1 is stored.

る。The crawler frame 23 has a front and rear direction.
A driving wheel 25, a driven wheel 26, and a rolling wheel 27 are arranged, and the crawler 14 is wound around them. The support leg 1 is mounted on the chassis frame 1 by means of lateral support leg mounting pins 3 that pass through the mounting holes.
It is attached to the outer side of the front portion of No. 0, and is rotatable around this support leg attachment pin 3. When the combine is advanced with the lower end of the support leg 1 grounded, the combine leg 1 pivots around the grounding point of the support leg 1 and stands up to the chassis frame 10 and the crawler 1.
The front part of 4 can be levitated from the ground plane. When the front part of the combine is lowered from the floating state, when the combine is moved backward, the supporting leg 1 rotates about the grounding point, reaches the state of FIG. 1, and the crawler 14 is grounded over the entire length.

At this position, a spring receiver 4 is projected at a position sufficiently distant from the center of rotation of the supporting leg 1, and one end of a coil spring 9 is inserted and attached. The other end of the coil spring 9 is attached to one end of a wire 15. ing. Wire 15
Is rotatably attached by a hydraulic cylinder pin 13 to a hole provided in the tubular portion of the hydraulic cylinder 2 through the inside of the machine body. The outer wire 6 that wraps the wire 15 is
Both ends thereof are adjustably fixed by wire fixing fittings 5 and 7 provided on the chassis frame 10.

In storing the vehicle body levitation device, when the supporting leg 1 on the driver's seat side is rotated forward and upward, the hydraulic cylinder 2 is moved through the coil spring 9 and the wire 15.
Is pulled forward and rotated around the pin 13 to be stored in a position in contact with the constituent members of the chassis frame 10.

While the coil spring 9 is extended, the coil spring 9 continues to rotate to reach the storage position, and pins are inserted into the storage fixing hole 11 and the pin hole 12 to be connected to the chassis frame 10. After the vehicle body levitation device is housed, the support leg 1 and the hydraulic cylinder 2 attract each other due to the tension of the coil spring, so that the gap between the mounting portions can be eliminated and the noise generated from the relevant portion during traveling can be reduced.

るものである。Regarding the interlocking mechanism of the supporting leg 1 and the hydraulic cylinder 2, instead of the wire 15, a rod mechanism, a link mechanism, a hydraulic mechanism or the like may be used for interlocking. 5 to 9, a point different from the above example is that the hydraulic cylinder 2 and the lock claw 31 are connected by a lock interlocking wire 29,
In the state where the hydraulic cylinder 2 is not housed, the lock claw 31 fixes the power steering lever 22 at the intermediate position, so that the reaper 16 cannot be operated up and down, and the combine cannot perform the reaping work. Since the user notices that the hydraulic cylinder 2 is forgotten to be stored, the damage to the relevant portion and the traveling obstacle due to the straw waste discharged to the field are prevented in advance.

行なうことができる。When the hydraulic cylinder 2 is rotated forward and upward for storage, the arm 28 fixed to the hydraulic cylinder also rotates, pulling the lock connecting wire 29 attached to one end of the arm 28 and removing the lock connecting wire 29. Since the lock pawl 31 connected to the end is rotated around the lock pawl pin 34 against the tension of the return spring 32, the lock pawl 31 is locked by the lock pawl 31 provided integrally with the power steering lever 22. When the power steering lever 22 is released, the power steering lever 22 is opened and a predetermined operation can be performed.

When is rotated downward, the lock claw 31 and the lock interlocking wire 29 are pulled by the tension of the already-expanded return spring 32, and the lock claw 31 is locked by the lock claw pin 34.
Since the power steering lever 22 is fixed by turning around the center of the hydraulic claw, it locks into the locking claw locking part, and the power steering lever 22 is fixed.
It is possible to detect a state in which the housing is not housed, and it is possible to prevent damage or the like as described above.

た。In the case where the support leg 1 and the hydraulic cylinder 2 are connected as shown in FIG. 1, the same effect can be obtained by interlocking the support leg 1 and the lock claw 31 with the lock connecting wire 29. Figure 1
The difference from the above example in FIGS. 0 to 11 is that the hydraulic cylinder 2 is used as an earth discharging plate. Hydraulic cylinder 2
Is configured to be fixed at an arbitrary angle rearward according to the working condition.

る。12 to 14 is different from the above example in that the ground plate 38 of the hydraulic cylinder 2 is formed in a disk shape, and the mounting direction is changed by the ground plate pin 39 so that it can be used as an auxiliary wheel. By using the expansion and contraction of the hydraulic cylinder 2, when lowering the combine to the stepped ground, auxiliary tools such as an eddy plate are unnecessary. 15 is different from the above example in that the reduction spring hydraulic cylinder reduction spring 40 of the hydraulic cylinder 2 is also used as a tumbler spring for housing this hydraulic cylinder.

It is configured so that it is forcibly switched to a certain tank port T. That is, the hydraulic cylinder pin 13, which is the rotation fulcrum of the hydraulic cylinder 2, extends toward the outer side of the machine body and is integrally connected to the hydraulic cylinder storage lever 42 at a position where it penetrates the chassis frame 10.
By operating this, the hydraulic cylinder 2 can be operated and rotated to the storage position.

Is fixed. When the hydraulic lever 43 is operated to the P position, the hydraulic pressure passes through the P to C circuits and applies the hydraulic pressure to the hydraulic cylinder 2 to extend it. At this time, the spring pins 47, 4
Since 8 is bending the U-shaped return spring 46 in the opening direction, this restoring force automatically returns to the neutral position when the hydraulic lever 43 is released, and the hydraulic cylinder 2 stops the extension.

The hydraulic lever 43 stays in the Q position, and the CT circuit remains open as shown in FIG.
Due to the body weight and the hydraulic cylinder pulling spring 40, the hydraulic fluid in the hydraulic cylinder 2 flows out through the C to T circuit, and the hydraulic cylinder 2 can be easily shortened.
