Description

[Detailed explanation of the idea] (Industrial application field) The present invention relates to a mounting device for a muzzleloading work machine.

(Prior art) For example, when attaching a front loader to a tractor, as shown in Japanese Utility Model Application No. 58-45762,
A pair of left and right cradle openings are provided on both the left and right sides of the tractor body, and a tapered cradle is formed in the cradle by making the inner surface of the front wall part tilt forward. A taper part is formed at the bottom of the left and right mounting bodies of the front loader to have a tapered shape that corresponds to the taper receiving part and is connected to the taper receiving part, and the taper part is pressed downward against the tapered receiving part by a bolt. It may be fixed in shape.

The above-described structure has the advantage that the left and right mounting bodies of the front loader can be mounted on the cradle of the tractor body without rattling.

(Problem to be solved by the invention) However, in the above-mentioned device, due to long-term use or vibration of the front loader, the taper part digs into the taper receiving part, and as a result, it is difficult to remove the front loader from the tractor. At the time, there was a problem in that the tapered part could not be easily removed from the tapered receiving part, and the front loader could not be easily removed from the tractor.

An object of the present invention is to provide a mounting device for a front loader that can solve the above problems.

(Means for Solving the Problems) In order to achieve the above object, the present invention is characterized by providing a pair of left and right cradle 8 opening upward on the left and right sides of the tractor body 1. Installation work machine 1
A tapered portion 21 is formed on the left and right mounting bodies 13 of 2 so that the front surface thereof is tilted forward.
In the device in which each tapered portion 21 is removably fixed in the pedestal 8 by pressing downward, the tapered portion is rotatable about the horizontal axis 10 in the left-right direction between the left and right side walls of each pedestal 8. 21 is provided with a roller 11 movably in contact with the front surface of the roller 11.

(Function) According to the present invention, when the muzzleloading machine 12 is attached to and detached from the tractor, the tapered portion 21 of the mounting body 13 is fitted into and removed from the inside of the pedestal 8, and the roller 11
relatively rolls on the front surface of the tapered portion 21.

(Embodiment) An embodiment of the present invention will be described below with reference to the drawings. In Fig. 2, 1 is a tractor body, 2 is a front wheel, 4 is a front wheel bearing stand, 5 is a bumper, 6 is a steering handle, 7 is the bonnet.

Reference numeral 8 denotes a pair of left and right pedestals, which are disposed on both left and right sides of the tractor body 1 and erected on a support base 9 fixed to the tractor body 1.

As shown in FIGS. 1 and 3, the pedestal 8 is
It has a U-shape in plan view that opens upward and forward, and a horizontal shaft 10 in the left and right direction is provided between the vertical center of the left and right side walls, and a roller 11 is rotatably mounted on the horizontal shaft 10. It is fitted.

Reference numeral 12 denotes a front loader shown as an example of a front loading work machine, and a pair of left and right mounting bodies 13 are installed in an upright manner.
, a pair of left and right lift arms 14 whose base ends are pivotably supported on each mounting body 13 so as to be able to rise and fall freely, and each mounting body 13
and a pair of left and right lift cylinders 1 that are interposed between each lift arm 14 and move the lift arms 14 up and down.
5, a bucket 17 exemplified as a working part that is pivotally supported at the tip of the lift arm 14 by a support shaft 16 in the left and right direction, and a working part cylinder that is interposed between the lift arm 14 and the bucket 17 and rotates the bucket 17. A pair of left and right bucket cylinders 18 and both lift arms 14 are removably connected, and when the front loader 12 is attached or detached, the bucket 1
It is provided with a pair of stands 19 which are provided on the mount 7 and prevent its rotation with respect to the ground, and a pair of left and right places 20 which project forward from the mounting body 13.

The lower part of the mounting body 13 has a front surface tilted forward to form a tapered part 21, and the tapered part 21 is fitted into the pedestal 8 to form the tapered part 21.
A roller 11 is in contact with the front surface of the roller 11 so as to be relatively movable.

22 is a bolt bolt, which has a pedestal 8 and a tapered part 2.
1 in a horizontally removable manner, and fixes the tapered part 21 downwardly against the pedestal 8 in a pressing manner, and the tip side has a rectangular cross section and a sloped surface 23 on the lower surface. It has a tapered wedge part 24, and has a bolt part 25 with a circular cross section on the base side.

The insertion hole 26 in the side wall of the tapered part 21 through which the wedge part 24 is inserted has a part of the side wall part of the tapered part 2.
1 by being bent inside the wedge portion 24.
The wedge portion 24 is releasably tapered and connected in a tapered shape corresponding to the above.

Further, a pair of nuts 28 and 29 having a rotating handle 27 are removably screwed onto the bolt portion 25. Note that the inner nut 28 has a cylindrical portion 30.
is fixed. 31 is a reinforcing plate.

A fitting part 32 is provided at the front of the brace 20, and the fitting part 32 is tapered and removably fitted to a support member 33 that stands up from the front vehicle bearing stand 4 from above. In addition, the front part of the brace 20 is
The support member 3 is attached via the lever 34 and the fixture 35.
It is detachably fixed to 3.

According to the embodiment configured as described above, when attaching the front loader 12 to the tractor, the second
As shown by the imaginary line in the figure, the bucket 17 is grounded and its rotation with respect to the ground is prevented by the stand 19, and the mounting body 13 is mounted at a higher mounting position than the normal mounting position shown by the solid line in Fig. 2. I'll leave it as that.

In this state, position the tractor at a position corresponding to the front loader 12, and move the bucket cylinder 18
is operated to lower the mounting body 13 so that its tapered portion 21 is fitted into each pedestal 8, and the fitting portion 32 is tapered fitted into the support member 33.

At this time, the roller 11 relatively rolls on the front surface of the tapered portion 21, so that the tapered portion 21 is easily fitted into the pedestal 8.

Next, insert the bolt 22 through the taper portion 21 and the pedestal 8, and then attach the nut 2 to the bolt 22.
By screwing 8 and 29 together, the tapered portion 21 is fixed downwardly to the pedestal 8 in a pressing manner, and the mounting body 13 of the front loader 12 is mounted on the pedestal 8 without wobbling.

Further, the front portion of the brace 20 is fixed to the support member 33 using a lever 34 and a fixture 35.

Next, when removing the front loader 12 from the tractor, the front loader 12 can be removed from the tractor by performing the work in the reverse order to the above.

By the way, in the above case, since the roller 11 which is rotatable around the horizontal axis 10 in the left and right direction is provided between the left and right side wall portions of the pedestal 8, the tapered portion 21 is inserted into the pedestal 8. The tapered portion 21 does not become stuck and cannot be easily removed, but due to the rolling of the roller 11 relative to the front surface of the tapered portion 21.
can be easily pulled out from inside the pedestal 8.

(Effects of the invention) As described in detail above, according to the invention, the mounting body of the muzzleloading machine can be securely mounted on the right and left cradle of the tractor body without rattling, and the taper of the mounting body can be The parts can be easily attached to and detached from the pedestal.
The present invention has the above advantages and is of great practical benefit.
