Description

[Detailed Description of the Invention] (Field of Industrial Application) This invention is based on the invention, in which top mat seedlings, paper pot-shaped mat seedlings, or only seeds are placed flat in a box and germinated as they are to form a mat. This is a planting device that plants mat seeds, which are made by putting soil or other seedling-raising material into a small box, sowing seeds, germinating them, and making them into a mat. This invention relates to a rank-type planting device that generates less vibration and has a simple configuration.

(Prior Art) As a prior art of this type, there is one in which a single seedling planting body is operated in a closed loop curve by a driving rotating crank and a swinging crank to plant one row of seedlings.

(Problems with the prior art) In the prior art described above, one row of seedlings is planted using one seedling planting body, so when planting at a high vehicle speed (high-speed planting In this case), the rotational speed of the seedling planting body inevitably increases, causing the seedling planting device to vibrate, making it impossible to perform a good seedling planting operation. In addition, there are some devices that have a balancer installed in the rotary drive crank to suppress this vibration, but at present, even a balancer cannot suppress this vibration, which is the biggest problem with seedling planting devices. .

(Means for solving the problem) In order to solve the above problems, the present invention provides a closed loop curve (A
), the planting device (2) reciprocates between the platform (1) and the field to plant seedlings or mat seeds in the field. 3a) and (3b).

A planter configured to operate the plurality of planting bodies (3a) and (3b) by rotating cranks (4a) and (4b) and swinging cranks (5a) and 11 (5b) without interfering with each other. In the attachment device (2)..., a rotary crank (4a) is provided so as to penetrate from one planting body (3a) l side to the other side, and the other planting body (3b
) is connected to a rotating crank (4b) for driving and rotating the planting device.

(Effect of the invention) Since one row of seedlings or mat seed rows is planted using multiple planting bodies, even if the vehicle speed is increased to perform high-speed planting, the rotational speed of each individual planting body is It is much slower than the conventional one, and the vibration of the planting device is sufficiently suppressed, allowing for good planting work. Further, since a plurality of planting bodies are operated by a rotating crank and a swinging crank, a good planting device with low production cost and less trouble can be obtained. Furthermore, since it is a combination of rotary cranks that drive and rotate other planting bodies from the tip of the rotating crank that penetrates from one side of one planting body to the other side, it is possible to plant multiple plants. Although it is a device that drives and rotates the body, it has a simple structure, and since rotation cranks are arranged on the left and right sides of the planting body, the planting device can be configured very compactly.

Seedling planting work is carried out, and in particular, each seedling planting device (
2) Each has two seedling planting bodies (3a) and Φ(3b) that are out of phase by 1800 degrees, so one row of seedlings is divided into two seedling planting bodies (3a). - Seedlings will be planted in (3b), and even if the vehicle is moved forward at high speed to perform high-speed planting, the individual rotational speeds of the seedling planting bodies (3a) and (3b) will be half of the conventional one. However, since the two seedling planting bodies (3a) and (3b) are set 180 degrees out of phase, they rotate extremely smoothly and do not generate large vibrations. Good seedling planting work can be performed.

Further, a driving rotation crank (4a) for driving and rotating the seedling planting body (3a) is provided to penetrate from the inside of the seedling planting body (3a) toward the outside, and the tip portion penetrating to the outside A sub-rotation crank (4b) for driving and rotating the seedling planting body (3b) is connected to the seedling planting body (3a) and (3b).
