Description

[Detailed description of the device] "Industrial application field" The present invention is a planting machine for planting a seedling for one plant from a seedling table that reciprocates left and right by picking it with a planting claw and sequentially planting it in a field. Regarding the device.

"Prior Art" Conventionally, as disclosed in Japanese Utility Model Laid-Open No. 59-98717, there has been a technology for mounting a seedling take-out amount adjusting lever and the like on the lower surface side of the lower end of the inclined seedling table.

"Problems to be solved by the device" In the conventional technology, the horizontal shaft body is provided in the frame for mounting the flattening float for the flat surface, and the seedling take-out amount adjusting lever is connected to the seedling mounting table side through the horizontal shaft body. , The frame or the horizontal shaft is easily deformed and damaged by external pressure, and the lever seedling removal amount adjustment position of the lever is likely to be different from the set position due to mechanical vibration, etc., and the seedling removal amount is changed due to the deformation or displacement. There was a functional problem that could not be easily prevented.

[Means for Solving Problems] Therefore, the present invention is an apparatus in which the seedling table (13) is supported by the planting case (17) so as to be reciprocally movable to the left and right, and in a side view, the planting case (17) is used. ) Vertical / horizontal feed drive section (17a) and transmission chain section
(17b) to (17f) and the seedling table (13) form a triangular space (4
8) is provided, the horizontal shaft body (35) is installed in the left and right direction above the transmission chain parts (17b) to (17f) of the triangular space part (48), and the base of the seedling removal amount adjusting lever (36) is provided. End the horizontal shaft body (35)
, And the horizontal axis body (35) and the horizontal axis body (35) are respectively connected to the quadrangle by the arm body (34) in a plan view, and the horizontal axis body (35) is connected to the seedling taking-out plate (15) and the horizontal axis body (35). (35) is a horizontal transmission frame that connects the left and right transmission chain parts (17b) to (17f) together.
It is provided between the (39) and the seedling take-out plate (15) substantially parallel to them.
