Description

[Detailed Description of the Invention] This invention relates to a transport vehicle for a planting work machine of a riding rice transplanter. The horizontal dimensions of the seedling tank of the planting machine have become wider, and when driving on the road, it is no longer possible to move the seedling tank horizontally in the road width direction. The seedlings were removed from the body and transported onto another transport vehicle with the sides of the seedling tank facing forward and backward.

However, the planting device is attached to the rear of the machine frame body of the planting machine, and in front of it is installed a seedling tank that is tilted so that the front side is upward, and a soil leveling float that extends long from below the planting body to the rear. When transporting a long planting machine on a transport vehicle, it is necessary to have a support stand with a wide width on the left and right sides of the vehicle. Not only that, but it was also necessary to provide a very high support stand for the planting machine to prevent the back of the float from coming into contact with the outer periphery of the wheel.

This invention aims to eliminate this drawback and has taken the following technical measures.

That is, in the present invention, a ground leveling float 42 is attached to the lower side of the planting section main body 41, and a float 42 for leveling the ground is attached to the upper side of the main body 41, and a float 42 that protrudes forward (larger than the main body 41) from the lower part of the rear side to the upper part of the front side. A seedling tank 43 is provided, and a planting body 44 facing the lower end of the seedling tank 43 is provided on the rear side of the main body 41.
In a transport vehicle 6 for transporting the planting machine 4, which is equipped with a A support frame 64 is provided to support the float so that it can be swung up in the front-back direction, and running wheels 62 are installed at the bottom of both left and right sides of the support frame 64. The wheels 62 on one side are positioned below the leveling float 42, and the wheels 62 on the other side are positioned below the leveling float 42. The wheels 62 are provided below the seedling tank 43 (in a related position) to form a transport vehicle for a planting machine of a riding rice transplanter.

One embodiment of the present invention will be described in detail with reference to the drawings. Reference numeral 1 denotes a passenger vehicle body, which has a pair of left and right front wheels 11 and a rear wheel 12. The front and rear wheels 1L12 are driven to run, and the vehicle body 1
A driver's seat 13 and a spare seedling tank 14 are provided on the top.

Reference numeral 2 denotes a link mechanism, in which the bases of the upper link 21 and lower link 22 are pivotally connected to a vertical frame 23 at the rear of the vehicle body, and both links 21 and 22 on the rear tip side are pivotally connected by a vertical connecting frame 24 so that they are parallel to each other. A hydraulic cylinder device 25 is interposed between the passenger vehicle body 1 and the upper link 21 so that the link mechanism 2 can be moved up and down.

Reference numeral 3 denotes an attachment/detachment device, which is installed on the vertical connection frame 24 of the link mechanism 2, and configured so that an engagement body 32 is actuated by an operating lever 33 to engage/detach a mounting hitch 31 of a planting machine, which will be described later. There is.

Reference numeral 4 denotes a planting work machine, in which a planting body 44 is attached to the rear end of a main body 41 which also serves as a planting mission case, and a planting body 44 is attached to the front side of the main body 41, with the rear side being lower and facing upward (slanted in side view). A shaped seedling tank 43 is attached to move back and forth from side to side, and a soil leveling float 42 is attached to the lower part of the main body 41. The front part of this float 42 is located below the seedling tank 43, and the rear part is used for planting. It is provided so as to extend rearward from the inclusion body 44.

Reference numeral 5 denotes a stand which can be rotated up and down by a support shaft 52, and has a triangular shape in side view and has a grounding side 52.

Reference numeral 31 indicates a hitch that can be attached to and detached from the engagement body 32 of the attachment and detachment device 3.

Reference numeral 6 denotes a transport vehicle, which has a pair of wheels 62 with a small diameter on both the left and right sides of a loading platform 61, and a support frame 64 that tilts in the left-right direction (in this direction) is provided at the middle of the left and right sides of this loading platform 61, and the support frame 64 is used to carry out the planting operation. The back surface of the front and rear intermediate portions of the float 42 of the machine 4 is supported so that the planting machine can be mounted on the carrier.

Reference numeral 63 indicates a towing pitch, and the vertical connection frame 24 of the passenger vehicle body 1
A removable O is provided.

Next, to explain the function of the upper side, in order to mount the planting work machine 4 removed from the link mechanism section of the passenger vehicle body 1 on the transport vehicle 6, the back side of the float 42 of this planting work machine 4 must be attached to the support frame. 64 and stacked horizontally as shown in FIG.

Then, the rear of the float 42 is swung upward and mounted, so that the wheels 6 located at the lower rear of the float 42
2 (The floats do not touch each other, and the front part of the seedling tank 43, which is tilted upward, is also lowered so that the front end is not in a very high position, and the center of gravity is located at the middle of the front and back.) The planting work machine 4 can be mounted in an extremely stable state as it moves.

As described above, since the present invention has the above-mentioned structure, the wheels are arranged at the lower part between the front and rear widths of the planting machine, so that it can be operated satisfactorily even on narrow roads. It can be stably mounted in the lower position, and the upper end of the seedling tank can also be lowered, making it easier to transport.
