Description

Detailed Description of the Invention

[0001]

BACKGROUND OF THE INVENTION 1. Field of the Invention The present invention relates to a stand device for a tilling work machine detachably mounted on a traveling machine body such as a tractor.

[0002]

2. Description of the Related Art Conventionally, a stand for detaching a tilling implement mounted on a tractor from a traveling machine body to maintain the posture in an upright posture has a rod rod on one side surface of a rotary cover covering a rotary portion of the tilling implement. It is known that the stand is shaped so that it can be attached by switching between a storage posture in which the stand stands upward and a stand posture in which the stand stands downward.

[0003]

However, the conventional stand device has a rotary portion (cultivating claw) which is grounded on the ground.
Since the grounding part of the and the grounding part of the stand are close to each other, it is unstable to maintain the posture of the tiller. Further, since the structure is such that an excessive force is applied to the stand and its mounting portion, there is a drawback that the structure becomes complicated, such that the structural members of both must be reinforced with high rigidity. Further, the means for switching the mounting of the stand with respect to the rotary cover is constituted by a pin or a mounting bolt, and there is a problem that it is difficult to operate due to clogging of mud or rust.

[0004]

The present invention has been achieved in order to solve the problems of the above-mentioned conventional device.
The cultivating work machine 1 is provided on the traveling machine body 3 so as to be vertically movable and removable.
While extending the tool bar 4 on this tiller 1,
In the tiller working machine supporting the supporting rod 40 on the tool bar 4, a stand 20 for supporting the tiller working machine 1 in an upright position on the supporting rod 40 is inserted and supported through a rotation switching mechanism 21, and the stand 20 is stored. It is provided so as to be switchable between a posture and a stand posture.

Further, it is characterized in that the stand 20 is oriented toward the driver's seat 3b of the traveling machine body 3 in the retracted posture, and can be switched from the driver's seat 3b to the stand posture.

As described above, since the posture can be switched between the two postures, the rotation switching mechanism 2 is attached to the support rod 40.
By switching and rotating the stand 20 mounted via 1 from the retracted position along the toolbar 4 to the stand position, the tiller 1 can be stably supported in the standing position by the stand 20 and the rotary portion 12. .

[0007]

Embodiments of the present invention will now be described with reference to the drawings. As shown in FIG. 1, reference numeral 1 is a tilling work machine having a stand device 2 of the present invention, and is attached to and detached from a hitch 30 provided on a lifting link 3a arranged at a rear portion of a traveling machine body 3 such as a tractor via a top mast 10. It is designed to be installed as much as possible.

The tiller 1 supports a rotary portion 12 having a tilling claw 11 laterally rotatably in a body frame 1a having a top mast 10 such that the rotary portion 12 can be rotatably driven, and a rotary cover 13 is provided above and behind the rotary cover 13. It is covered with the rear cover 13a. As shown in FIGS. 1 and 2, two tool bars 4 are provided at the center of the machine body frame 1a so that the mounting height can be adjusted by an adjusting screw rod 5 with a handle provided on the top mast 10. It is supported and extended backwards.

A support rod 40 having a polygonal cross section (a quadrangular shape in this embodiment) capable of mounting and supporting another working machine (not shown) having a tail wheel or the like at the rear end portions of the two toolbars 4.
Is fixed laterally, and a stand device 2 for maintaining the tilling implement 1 in an upright posture by using an intermediate portion of the support rod 40 is attached so that it can be easily switched between a storage posture and a stand posture. There is.

As shown in FIGS. 4 and 5, the stand device 2 has a mounting portion 21 which is provided on the base side of a rod-shaped stand 20 and which is composed of a rotation switching mechanism, and is fitted to a support rod 40. The position with respect to the support rod 40 can be adjusted. Further, as shown in FIG. 3, a supporting rod 41 is extended from the supporting rod 40, and when the stand 20 is housed by a supporting body 42 made of rubber attached to the tip of the supporting rod 41, it is sandwiched by the supporting body 42 and predetermined. It is designed to be fixed in a posture.

The mounting portion 21 is a support rod 40 having a square cross section.
The positioning member 2 fixed to the cylinder shaft 23 by fitting the cylinder shaft 23 into the cylinder shaft 23 and fitting the bracket 25 onto the outer surface of the cylinder shaft 23.
6 are arranged on both sides of the bracket 25. A holder 27 is provided on the bracket 25, and the tip of the stand 20 is supported between the holder 27 and the bracket 25.
The ends of the bolts 22, 22 screwed on both sides of 3 are supported by the rod 4.
The position on the support rod 40 can be adjusted by pressing on the surface of 0.

The stand 20 is attached to the stand 20 with its base side slidably inserted into a holder 27 having a U-shaped cross section fixed to the bracket 25 and a hole formed in the bracket 25. A fixing hole 2 in which the end of the stand 20 is opened to the cylindrical shaft 23 by a spring 29 compressed between the stopper 28 and the holder 27.
3a is inserted into the support rod 40, and its end face is in pressure contact with the lower end face 40a formed on the support rod 40. Further, the cylindrical shaft 23 has a fixing hole 23b that is directed toward the driver's seat 3b of the traveling machine body 3.

The tiller 1 constructed as described above has the stand 20 fixed to the fixing hole 23 of the cylinder shaft 23 at the time of tilling work.
It is fixed in a state in which it is inserted into b and the side surface of the support rod 40 is pressed, and as shown in FIG. It can be compactly stored. When the cultivating implement 1 is to be separated from the traveling machine body 3, the cultivating implement 1 is moved upward as shown in FIG. Then, when the worker can operate the stand 20 from the driver's seat 3b, the stand 20 is pulled out from the fixing hole 23b on the driver's seat 3b side and is rotated upward in the arrow direction. While being slidably in contact with the outer periphery of the cylinder shaft 23, the spring is pressed into the downward fixing hole 23a by the spring 29 and is fitted and positioned and fixed in the suspended stand posture.

Then, the elevating link 3a of the traveling machine body 3 is lowered to lower the tiller implement 1, so that the tiller implement 1 has a rotary portion 12 on the front side as shown in FIG.
The grounding is performed by the lowermost plowing claw 11, and the leg portion of the stand 20 which is supported on the rear side of the rotary portion 12 at the rear side of the rotary portion 12 is placed in a stable standing state.

In this state, the hitch 30 is disengaged, and then the traveling machine body 3 is moved forward, whereby the tilling implement 1 can be easily and accurately separated from the traveling machine body 3. Further, when the cultivating implement 1 is reattached, the cultivating implement 1 is erected in the original correct stable posture,
The cultivating implement 1 can be efficiently mounted by the reverse operation to the above.

[0016]

According to the first aspect of the present invention, the tool bar is used to mount the rotation switching mechanism on the supporting rod and the stand is provided so that the posture can be switched, so that the stand can be stored without hindering the storage. In addition, since it can be grounded with a sufficient distance from the grounding part of the rotary part in the stand posture, the tiller can be supported in a stable state, and the stand device is simple and has high rigidity. Can be

According to the second aspect of the present invention, the stand can be left attached without removing it during cultivating work, and when the stand is used, the driver's seat can be switched to the stand posture by a simple operation. Work can be done efficiently.
