Description

[0001]
BACKGROUND OF THE INVENTION
The present invention relates to simplification of an operation monitor panel and a marker support structure in a riding rice transplanter.
[0002]
[Prior art]
The riding rice transplanter is provided with a pair of left and right drawing markers that draws the position where the left and right centers of the machine pass in the next stroke on the surface of the field when performing work while turning the field. A drawing marker operation lamp for displaying which one of the pair of left and right drawing markers is in an active state is provided on the operation monitor panel.
[0003]
In addition, when the pair of left and right direction indicators that indicate the direction of turning when traveling on the road is in a position that cannot be seen by the operator, a direction indicator lamp that displays which direction indicator is in the active state is displayed on the monitor. It is necessary to install on the panel.
[0004]
[Problems to be solved by the invention]
If the drawing marker operation lamp and the direction indicator lamp are provided on the monitor panel, the monitor panel becomes complicated, and both the lamps are provided in a pair on both the left and right sides. It is a design problem how the drawing marker operating lamp and the direction indicating lamp are provided on the monitor panel. Therefore, the present invention has an object to make the drawing marker operation lamp and the direction indicating lamp coexist while simplifying the monitor panel. Moreover, when the side marker (44) indicating the position of the outermost existing vegetation planted in the previous process is provided in addition to the drawing marker, only the drawing marker is stored, and the course is determined using only the side marker. It is also an object of the present invention to provide a configuration that can be performed.

DETAILED DESCRIPTION OF THE INVENTION
Hereinafter, the present invention will be specifically described with reference to the drawings.
A riding rice transplanter 1 shown in FIGS. 1 and 2 has a seedling planting portion 4 mounted on the rear side of a traveling vehicle body 2 via a lifting link device 3 so as to be movable up and down, and a fertilizer application device 5 at a rear portion of the traveling vehicle body 2. The main parts of each are provided.
[0007]
The traveling vehicle body 2 is provided with front wheel final cases 11 and 11 on the left and right sides of the transmission case 10 disposed at the front of the airframe, and the front wheels 12 and 12 are pivotally supported on the case so as to be able to change the direction. A rear wheel final case 15 is provided at both left and right ends of a left and right rear frame 14 that extends rearward from the rear portion of the main frame 13 and is connected to and integrated with the rear end of the main frame. 16 and auxiliary rear wheels 17 and 17 are pivotally supported.
[0008]
An engine 20 is mounted on the main frame 13, and the rotational power of the engine 20 is transmitted to the transmission case 10 via the first belt transmission device 21 and the continuously variable second belt transmission device 22. A main clutch is provided at the input portion of the mission case 10. A part of the rotational power shifted by the main transmission in the mission case 10 is transmitted to the front wheels 12, 12 and the rear wheels 16, 16, 17, 17 to cause the traveling vehicle body 2 to travel. The transmission system for the rear wheels is provided with a rear wheel differential device and a rear wheel brake device capable of individually braking the left and right rear wheels. The remainder of the rotational power shifted by the main transmission is transmitted to the seedling planting unit 4 and the fertilizer application device 5 via the planting clutch 23.

Furthermore, a center marker 45 is provided at the left and right center of the front end of the aircraft to determine the course of the aircraft by visually matching the lines drawn on the field by the drawing markers 43 and 43.
[0014]
As shown in FIGS. 4 and 5, the drawing marker 43 is composed of a marker arm 43a that is rotatable about a longitudinal axis 46 and a drawing action body 43b that is vertically attached to the tip of the marker arm. When the wire 47 is pulled in conjunction with the expansion / contraction operation of the lifting cylinder 56 described later, it becomes an inactive state (indicated by a solid line in FIG. 4), and when the wire 47 is loosened, the leading end of the drawing action body 43b is in the mud. The inserted action state (indicated by a chain line in FIG. 4) is obtained.
[0015]
The shaft 46 in the front-rear direction is provided at the outer end of a marker support frame 48 whose base is fixed to the horizontal frame 42a. The marker support frame 48 is bent at a folding fulcrum 48a at substantially the same position as the outer end of the auxiliary step 33. When not working, the marker support frame 48 is placed outside the auxiliary step 33 as shown by a chain line in FIG. It can be stored in a position adjacent to the edge.
[0016]
The side marker 44 is a vertical bar, and is supported by the side marker support bar 49 so that the lower end of the side marker 44 has a height close to the upper part of the existing seedling. The side marker support rod 49 is provided on the upper side of the marker support frame 48 so as to be rotatable about a position inside the bending support point 48a of the marker support frame as a fulcrum 48b. The side marker 44 can also be stored at a position adjacent to the outer edge of the auxiliary step 33 as shown by a chain line in FIG. At this time, the side marker support rod 49 is obliquely passed over the auxiliary step 33.
[0017]
By arranging the bending fulcrum 48a of the line drawing marker and the rotation fulcrum 48b of the side marker at the same position in the front-rear direction, a simple configuration can be achieved. Further, the side marker support rod 49 has a shape in which the outer end portion is bent forward, and the side marker 44 is positioned on the front side rather than the drawing marker 43, so that only the drawing marker 43 is stored rearward. It is possible to determine the course using only the side marker 44.
[0018]
The elevating link device 3 includes an upper link 51 and lower links 52, 52 that are rotatably attached to a link base 50 that is fixed to the rear end of the main frame 13. A vertical link 53 is connected. Then, a connecting shaft 54 fixed to the seedling planting part side is rotatably inserted and connected to a bearing part protruding rearward from the lower end of the vertical link 53, and the seedling planting part 4 is mounted so as to be able to roll in the traveling direction. Is done. When the elevating cylinder 56 is expanded and contracted, the elevating link device 3 moves up and down, and the seedling planting unit 4 moves up and down while maintaining a fixed posture.

【The invention's effect】
As described above, the riding rice transplanter according to the present invention functions as a drawing marker operation indicator lamp for letting an operator perceive which one of the pair of left and right drawing markers is in an active state during seedling planting work. Sometimes a monitor panel is simply configured by combining one indicator for two purposes so that it can function as a direction indicator to let the operator perceive which of the pair of left and right direction indicators is in action. As well as being able to prevent operator misdetection. In addition, even if side markers are provided separately from the drawing marker, both can be supported so that they can be stored well. Only the drawing marker can be stored rearward, and the course can be determined using only the side marker. .
