Problems solved by technology

[0009] However, in the structure of the elevating device of the seedling planting device of the conventional agricultural work machine, the engine speed will become high when the driving operation lever is located in the forward and backward stop area. When the seedling planting device is still in the middle of rising, the driving operation lever is moved to the low-speed driving position of the reverse, because the working machine has not been fully raised, it may come into contact with the field ridge, etc.

Embodiment approach 1

[0073] figure 1 It is a side view of a six-row type passenger rice transplanter as an example of the rice seedling transplanting work vehicle of the present invention, figure 2 for its top view. in addition, image 3 It is a block diagram for demonstrating the control processing mechanism of the riding rice transplanter of this embodiment.

[0074] (I.) First, using these drawings, it demonstrates centering on the structure of the riding rice transplanter 1 of this embodiment.

[0075] Such as figure 1 , figure 2 As shown, a six-row type passenger rice transplanter 1 as an example of a seedling transplanting operation vehicle is composed of the following parts: front and rear wheels (traveling device) 3, 4, which support the traveling vehicle body 2 in a manner that can travel in the field; Speed ​​change device 5, it transmits traveling power to these front and rear wheels 3,4 variable speed; Engine 6, it is the active part that provides power to each equipment that in...

Abstract

The invention provides a work vehicle, which does not need any stand-by time when the vehicle is stopped, and enables a work machine to rise in a shorter time during backward driving, and prevents speed of backward driving from excessively rising. A driving vehicle body is provided with a seedling planting device capable of being freely lift up and down, an engine, a variable speed gear which changes speed of the power of the engine and drives the driving device, and a driving operation rod which operates the variable speed gear to change the driving speed. The driving operation rod can be operated to a forward driving area, a forward and backward stop area and a backward driving area in order. The work vehicle also comprises a control device which controls the rotating speed of the engine and is arranged corresponding to the operation position of the driving operation rod. The control device enables the rotating speed of the engine when the driving operation rod is operated to a position adjacent to a low-speed side to be higher than the rotating speed of the engine when the driving operation rod is operated to the highest position in the backward driving area.

Description

technical field [0001] The invention relates to a working vehicle which connects working machines such as a seedling transplanting machine to the rear of the vehicle body to perform various operations, and belongs to the technical field of agricultural machinery. Background technique [0002] In the past, with regard to work vehicles connected with working machines such as seedling planting devices, for example, when the body was retreated on the side of the field bank during the seedling planting operation, in order to travel at a relatively low speed, many operating levers were operated. to set the engine speed to low rpm. However, if the engine speed is lowered by the above-mentioned method, the ascending speed of the lifting device for raising and lowering the rice seedling planting device driven by the power from the engine will slow down. [0003] Therefore, it is necessary to wait for the backward operation until the seedling planting device rises above the height at...
