Description

[Detailed description of the device]

[0001]

[Industrial applications]

 The present invention relates to a bonnet device for a mobile agricultural machine, such as a walking rice transplanter, which picks up one seedling from a seedling mounting table that reciprocates left and right by a planting claw and sequentially plants it in a field.

[0002]

[Prior Art]

 For example, in the bonnet of a walking rice transplanter, the mounting pivot of the rear end of the bonnet is fitted and supported on the mounting part of the machine body, and the front end side of the bonnet is hooked on the machine body by a spring member or the like to be mounted. ..

[0003]

[Problems to be solved by the device]

 However, in the case of such a bonnet installation, there is a drawback in that the positional displacement of the bonnet in the left-right direction is not regulated and the bonnet cannot be installed safely and stably.

[0004]

[Means for Solving the Problems]

 Therefore, in the present invention, in the structure in which the bonnet is attached to the machine body, the front and rear ends of the bonnet are attached to the machine body via the left and right regulation mounting shafts that regulate the lateral position deviation and the front and rear regulation mounting shafts that regulate the longitudinal position deviation. By removably fitting and supporting the side, it is possible to mount the bonnet properly and stably with one-touch operation with no displacement in the front-rear direction and the left-right direction.
