Description

[Detailed description of the invention] The present invention relates to a rice transplanter in which a seedling planting device is connected to the vehicle body via a swing link mechanism and a drive device that drives and swings the swing link mechanism so as to be able to move up and down. .

In the rice transplanter mentioned above, the seedling planting device is raised and lowered without significantly changing its posture back and forth, for example, in order to suppress changes in the planting posture and to prevent damage to the placed seedlings. However, as a result, the front-to-back length of the machine became quite large over the entire range of raising and lowering the seedling planting device, which was inconvenient when storing it in a warehouse or loading it onto a transport vehicle.

The present invention has been developed in view of the above-mentioned circumstances, and is intended to solve the above-mentioned inconvenience by allowing the longitudinal length of the aircraft to be shortened as necessary.

Embodiments of the present invention will be described in detail below with reference to the drawings.

As shown in Fig. 1, four pine-shaped seedlings W...
A slanted seedling stand 5 which is horizontally reciprocated at a constant stroke with... placed side by side side by side, and a 4 in which one seedling is taken out one by one from the lower end of each of the pine-shaped seedlings W... and planted. A seedling planting device 8 equipped with individual planting claws 6 .

The seedling planting device 8 is connected to the vehicle body so as to be movable up and down in a substantially parallel position by a swing link mechanism B consisting of a pair of upper and lower swing links 9 and 10 connected to the vehicle body so as to be able to swing up and down. At the same time, a hydraulic cylinder 11 is provided as a drive device for raising and lowering the lower swing link 10 with respect to the vehicle body. In order to avoid contact with the ground at times, etc., it is configured to be able to be raised and lowered.

As shown in FIG. 2, both the swing links 9, 1
0 and supports the front end of the hydraulic cylinder 1.
A frame body 12 that supports the front end of the frame body 12 is rotatably supported on the vehicle body so as to be rotatable around a horizontal axis X, and a worm 14 that engages with a wheel 13 fixed to the frame body 12 is supported on the vehicle body. Furthermore, a crank handle 15 for rotational operation is interlocked with the worm 14 by a bevel gear, and as shown in FIG. The vehicle body is constructed so that it can be folded down and stored by operating the handle 15. That is, the frame body 12 is configured to be rotatable upward via a drive mechanism C constituted by the wheel 13, the worm 14, and the handle 15.

Further, the free end of the arm 17, which is provided so as to be able to swing up and down with respect to the upper swing link 9 and to be fixed by a pin 16 in an attitude along the swing link 9, is used to raise the seedling planting device 8 to the maximum. In this state, the frame bodies of the vertical swing links 9 and 10 can be pivoted downward and fixed with a pin to the lower swing link 10, and even if oil leaks in the hydraulic cylinder 11, the frames of the vertical swing links 9 and The structure is such that the posture relative to 12 can be maintained at an appropriate posture.

Incidentally, in carrying out the present invention, the drive device 11 may be of various types other than a hydraulic cylinder.

Further, in implementing the present invention, when the seedling planting device 8 is driven by power from the vehicle body, it is preferable that the transmission mechanism is configured to allow the attitude of the seedling planting device 8 to be changed.

In summary, the rice transplanter according to the present invention includes a swing link mechanism B and a drive device 11 that controls the drive thereof.
is attached to a frame 12 that is swingably attached to the vehicle body A around the horizontal axis X on the upper end side, and the frame 12 is attached to the vehicle body A so that the frame 12 is swingable around the horizontal axis X on the upper end side.
It is characterized in that it is provided with another drive device C that swings around it.

That is, the swing link mechanism is attached to a frame body that is rotatable around the horizontal axis, and the frame body is rotated to lower the seedling planting device 8, which is raised to the maximum by the drive mechanism 11, against the vehicle body. Since the seedling planting device 8 can be stored in a horizontal position, the longitudinal length of the machine body can be shortened by storing the seedling planting device 8 lying down against the vehicle body when storing it in a warehouse or transporting it. Since the frame body to which the swinging link mechanism is attached is rotated and stored, for example, the upper link of the pair of upper and lower swinging links is constructed to be expandable and retractable, and the upper link is contracted. Therefore, compared to the case where the seedling planting device is stored on the vehicle body side, the longitudinal length of the machine body can be made shorter, which allows it to be stored even in narrow warehouses such as barns. , when shipping from the factory, more units can be loaded onto trucks or containers, and when stored in warehouses, more units can be stored, which has the advantage of reducing logistics costs. be.
