Abstract

PROBLEM TO BE SOLVED: To facilitate the operation of unit clutch levers during rice transplanting works. SOLUTION: This planting apparatus of a rice transplanter is equipped with a planting part (12) in a freely liftable manner at the rear side of a running part through a link mechanism (22) and longitudinal feed clutches. When a unit clutch (48), stopping a planting tine (14) of each planting unit, is shifted to off, a longitudinal feed clutch stops a longitudinal seedling-feeding member (43) corresponding to a planting tine (14) under interlocking. The planting apparatus is provided with unit clutch levers (57a), (57b), (57c) which intermittently operate the unit clutches (48) and the longitudinal feed clutches for each planting unit. The unit clutch levers (57a), (57b), (57c) are linked to the unit clutches (48) and the longitudinal feed clutches (68) through wires (56), (66).

Description

Detailed Description of the Invention

[0001]

BACKGROUND OF THE INVENTION 1. Field of the Invention The present invention relates to a planting apparatus for a multi-row planter planting machine, in which a plurality of planting cases provided in a planting section respectively drive and support planting claws.

[0002]

2. Description of the Related Art Conventionally, as shown in Japanese Utility Model Publication No. 57-53125, when a unit clutch and a vertical feed clutch are interlocked to stop a planting pawl, a seedling vertical feed member corresponding thereto is automatically stopped. There was a technique to make it.

[0003]

However, in the prior art, since the unit clutch lever is provided on the side of the planting portion, the planting work is interrupted and the planting portion is raised when the unit clutch lever is operated. However, there is a problem in handling operation such that the operator needs to move to the planting section side and the operation of the unit clutch lever is extremely troublesome.

[0004]

SUMMARY OF THE INVENTION However, according to the present invention, a unit clutch is provided on the rear side of a running unit so that a planting unit can be lifted and lowered via a link mechanism and a planting claw is stopped for each planting unit. In the planting device of the rice transplanter, which is provided with a vertical feed clutch that interlocks the seedling vertical feed member corresponding to the planting claw when turning off, the unit clutch and the vertical feed clutch are intermittently operated for each planting unit. A unit clutch lever is installed, and the unit clutch lever is connected to the unit clutch and the longitudinal feed clutch by tensioning the wire. It is possible to perform both the operation of stopping the planting claws and the seedling vertical feed member to reduce the number of planting rows and the operation of returning to the original number of planting rows in the running section. To perform resulting is to obtain aim and facilitate improvement in simplicity and work efficiency of handling operations.
