Description
BACKGROUND OF THE INVENTION 1. Field of the Invention The present invention relates to a working vehicle such as a seedling transplanting machine for seedling a seedling in a package.
The seedling transplanting machine as the working vehicle can attach and detach the seedling feeding device or the like to be the working device provided on the rear portion of the running vehicle body. This type of seedling transplanting machine is disclosed in Patent Document 1 below.
In the seedling transplanting machine shown in Patent Document 1, a receiving hitch is provided at a rear portion of a lifting link mechanism for lifting and lowering the seedling feeding device, and a mounting hitch of a working device such as a seedling feeding device is connected to the receiving hitch, As shown in FIG. The receiving hitch is provided with a rolling axis for rotating the working device around the axis in the longitudinal direction of the base.
In addition, a horizontal sensor for detecting the posture in the lateral direction is provided on the working device, and a rolling control motor for rotating the working device is provided on the base side. The seedling transplanting machine is configured such that the working device is rotated by the control motor until the planting apparatus is in a horizontal state, and the control motor is stopped when the working device is in a horizontal state.
Accordingly, even if there is unevenness on the packaging surface, the working device can be kept in a horizontal state, so that the working accuracy of the working device can be maintained.
However, in the seedling transplanting machine disclosed in Patent Document 1, when the elevating link mechanism and the working device are connected, the operator needs to move to the rear side of the traveling vehicle body and perform a locking operation. This reduces work efficiency and wastes extra labor . When a worker other than the worker who manages the running body performs the locking operation, the worker who manages the running body is not required to move, but there is a problem that the worker is increased by that amount.
An object of the present invention is to provide a work vehicle which can easily perform attaching / detaching work of a work device and does not require an extra work argument.
