Description

[Detailed Description of the Invention] The present invention relates to a vehicle body frame structure for a power carrier.

Conventionally, in a power transport vehicle in which a harvesting basket is removably mounted on a vehicle body frame and the harvesting basket can be freely dumped using a dump cylinder, when the harvesting basket is attached or removed, the harvesting basket is not moved. The same work is carried out by supporting the harvesting basket in a lifted state with pedestals, etc. and moving the vehicle body frame. There were disadvantages in that it was difficult and time consuming to place.

In the present invention, by providing a tapered part for guiding the harvesting basket on the main frame of the vehicle body frame, the harvesting basket can be attached to the body of the power transport vehicle reliably and quickly through the tapered part. It is intended to provide a frame structure.

The embodiment of the present invention will be explained in detail based on the drawings.
A indicates a multi-purpose work vehicle having a transportation function, and the work vehicle A has a prime mover section 2 and a cabin 3 on the left and right sides of the front part of the vehicle body frame 1, respectively, and Attach harvest basket 4.
It is configured to be removably mounted and to carry out transportation work using wheels 5 and 6 provided at the lower front and rear portions of the vehicle body frame 1, respectively.

In addition, PTO shafts 7 and 8 are protruded from the front and rear of the work vehicle A, and a front three-point linkage device 9 is installed on the front side of the prime mover section 2.
Alternatively, the required work equipment may be connected to the rear to enable versatile work to be performed.

The vehicle body frame 1 has a rectangular machine frame 11 connected to the front half of the left and right main frames 10, 10 formed in a longitudinally longitudinally longitudinal shape, and auxiliary frames 12 are constructed at required locations, and the prime mover section 2 and , the main frame 10 is configured to support the cabin 3, and the harvesting basket 4 is configured to be mounted and detachably placed on the rear half of the main frame 10, 10.

That is, the left and right main frames 10, 10
The center part of the second half is bent inward from the first half part arranged in a parallel opposed state with a required interval maintained, and tapered parts 13, 13 are provided, and the tapered part 1
The same frame 10, 1 located at the rear of 3, 13
0 are formed parallel to each other at narrow intervals, and a steering space S is provided on the outer side of the rear part of the frame 1.
Guide rollers 14, 14 are provided at the rear ends of the harvest baskets 14, 14 in a slightly outwardly extending manner, so that the harvesting basket 4 can be easily attached via the tapered portions 13, 13. .

Reference numeral 15 indicates a reinforcing frame horizontally suspended between the left and right main frames 10 and the rear halves of the 10.

The harvesting basket 4 has a rear side surface inclined rearward and upward to form an inverted trapezoidal box shape, and an opening 16 is provided at the top, and the upper machine frame 1 of the harvesting basket
The upper and lower ends of the dump cylinder 19 are connected between the center part of the harvesting basket 4 and the center part of the lower frame 18, and the basket support rod 21 is connected between the upper part of the rear machine frame 20 of the harvesting basket 4 and the rear end of the lower frame 18. The upper end of the support rod 21 is connected to the upper part of the rear machine frame 20 with a pivot 22, and the harvesting basket 4 is moved around the pivot 22 by the extension operation of the dump cylinder 19. It is configured to allow backward rotation.

At the front side of the lower frame 18, roller bodies 23, 23 are vertically disposed via pivots 24, 24 at the positions where the outer surfaces of the front half of the main frames 10, 10 contact, and at the rear of the lower frame 18. on the side,
At the rear end outer surface abutment positions of the main frames 10, 10, guide-cum-lateral slip prevention bodies 25, 25, which are formed by bending a laterally elongated plate body into a dogleg shape forward, are vertically provided.

Reference numeral 26 denotes a pedestal that is attached to the left and right front portions of the lower frame 18 so that it can be folded and stored, and 27 is a rear pedestal that is attached to the rear center portion of the lower frame 18 so that it can be folded and stored.

The embodiment of the present invention is constructed as described above, and when harvesting grass, the harvesting basket 4 is attached to the rear part of the body frame 1 of the multi-purpose work vehicle A having a transportation traveling mechanism, and the harvesting basket 4 is placed inside the harvesting basket 4. It is sufficient to load and transport the grass, and in this case, the work of attaching the harvest basket 4 is done by attaching the harvest basket 4 to the left and right front lower surfaces and the rear central lower surface of the lower frame 18 that supports the harvest basket 4. Then, the pillars 26, 26 and the rear pillar 27, which have been contracted and housed, are extended and hung down, and the harvesting basket 4 is moved by the pillars 26, 26, 27.
Support the main frame 1 at the required height, then tilt the multi-purpose work vehicle A in the same state and lift the main frame 1.
After positioning the rear half of the frame 10, 10 below the harvesting basket 4, the pillars 26, 26, 27 are contracted to place and fix the harvesting basket 4 on the rear half of the frame 10, 10. At this time, there is a tapered part 13 in the center of the second half of the main frame 10,
13, and a steering space S is provided at the rear outer side of the tapered portions 13, 13, so that the multi-purpose work vehicle A can be mounted on the main frame 10,
When the rear end of the main frame 10 is positioned between the roller bodies 23, 23 hanging down from the front side of the lower frame 18 of the harvesting basket 4 and is operated to move backward, the main frames 10, 10 are moved between the roller bodies 23, 23. It moves to the specified position while being guided, and then moves to the same frame 1.
The rear ends of 0 and 10 are guided and positioned between guide and lateral slip prevention bodies 25 and 25 hanging down from the rear side of the lower frame 18 via guide rollers 14 and 14,
At the same time, the center portions of the frames 10, 10 are positioned while being sandwiched between the roller bodies 23, 23, so that the work of placing the harvesting basket 4 can be completed reliably and easily.

According to the present invention, since the tapered part is provided in the middle part of the latter half of the left and right main frames, the structure is simplified and the strength of the frames is increased, and
Guided by the tapered part, the work of mounting and mounting the harvest basket can be done reliably, easily and quickly, and a space is formed outside the tapered part to ensure sufficient steering space for the rear wheels. There is an effect.

In addition, at the rear side of the lower frame, at the position where the rear end of the main frame comes into contact with the outer surface, a guide and lateral slip prevention body, which is made by bending a horizontally elongated plate into a dogleg shape, is installed vertically. Since the rear end of the main frame is guided and positioned by the lateral slip prevention body via the guide roller, the work of placing the harvest basket can be performed reliably.
