Abstract

PURPOSE:To facilitate the running of a transplantation machine on road and the housing of the machine and to protect the safety of a streaking marker by supporting a streaking marker on an upper bumper in a state to be held along a side of a seedling table when the right and left side bumpers are folded into a transplantation part to decrease the lateral width of the part. CONSTITUTION:The right and left side bumpers 76 having a structure to be foldable inward are attached to the outermost part of the right and left sides of a seedling table 16. Right and left streaking markers 87 are erectably supported on the side bumpers 76 foldable to the upper part at the rear side of a transplantation part 15. The streaking marker 87 is held along the side of the seedling table 16 in the case of folding the side bumpers 76. Accordingly, the streaking marker 87 can be stored safely in good state without being protruded upward or backward from the seedling table 16.

Description

[Detailed Description of the Invention] "Industrial Application Field" The present invention relates to a rice transplanter for rice transplanters in which the left and right outermost parts of the seedling platform are folded inward to reduce the total width of the seedling platform. Regarding mounting equipment.

``Prior art'' This rice transplanter is designed to reduce the total left and right width of the seedling table, and the lower guide rail and left and right side bumpers of the seedling table are also folded down to reduce the width of these pads. I'm letting you do it.

"Problem to be Solved by the Invention" With such a structure, the left and right striation markers are attached to the side bumper, and when the side bumper is folded and stored, the left and right striation markers are also stored inside the contact body. Although there is a means to do this, there is another problem in that it is difficult to store the seedlings reliably and safely because the tip end protrudes to the side, above, or behind the seedling stand.

Further, when both the lower guide rail and the left and right side bumpers are folded and stored, fixing fittings for storage and holding are required for each.

``Means for Solving the Problems'' Therefore, the present invention provides a structure in which left and right side bumpers provided at the left and right outermost parts of a seedling stand are folded inward, and left and right joint markers are attached to the side bumpers. The side bumper is supported in a manner that it can be raised and lowered freely, and the side bumper is provided so as to be folded and stored at the upper rear side of the planting section, so that when the side bumper is folded, the striped marker is stored along the side of the seedling stand. It is configured so that it can be retained.

Further, in the structure in which the left and right side bumpers provided on the left and right outermost parts of the seedling stand and the left and right outermost parts of the lower guide rail of the seedling stand are folded inwardly, the side bumpers and the guide rails are folded inwardly. The folding direction is set in a direction that intersects with the side bumper when viewed from the side, and the side bumper is folded so that the side bumper is overlapped on the outside of the guide rail when folded.

"Function" According to the present invention, when the left and right side bumpers are folded inward to the planting part to reduce the left and right width, the knot markers supported on the bumpers are also folded to the side of the seedling stand. The rice transplanter is housed in a state along the road, making it convenient to drive the rice transplanter on the road or storing it, and also to protect the safety of the harvesting marker.

In addition, when both the lower guide rail and side bumper of the seedling stand are folded and stored, the side bumper should be folded compactly so that it is stacked on the outside of the guide rail, and the side bumper should be stored and held using a position-fixing metal fitting or the like. Therefore, the position of the guide rail can be regulated by the bumper, and the guide rail can be easily and reliably stored, and safety can be ensured when the guide rail is stored by the bumper.

Further, the left and right ends of the lower rail (18) are divided by a certain length to form a divided rail body 118a), and the bracket (82) of the rail body (18a) is attached to the bracket on the central rail body f18b). (83) is the folding fulcrum shaft (8
4) so that they can be folded inward at approximately 90 degrees. In this case, the split rail body (18al) is folded at approximately 90 degrees with respect to the central rail body (f18bl), and is in a state along both left and right sides of the seedling stand body (18bl).
The pumper frame (71) has a split rail body (18al
On the outer side, as shown in FIG. 1, the side view rail body f1
8a), and when the frame (77) is stored and held by the positioning bin (81), the frame (77) is used to store the divided rail body (18al). It is constructed to ensure retention and safety protection.

Further, the base ends of the left and right striation markers (87) are supported at the distal end of the pumper frame (77) via a fulcrum shaft (85) and a marker mounting plate (86) in a freely undulating manner, and the pumper frame When the marker (87) is folded and stored, when the marker (87) is placed in the upright storage state by pulling the marker wire (88), the marker (87) is folded and stored.
In order to prevent the seedlings from protruding laterally or upwardly, the seedlings are stored and held with their tips along the outsides of the left and right folded seedling carriers (18a) at the upper rear side.

Furthermore, the marker arm (
An auxiliary hook (90) is provided in the middle part of 87al via an arm mounting bracket (89), and it can be attached to the marker (87al) during work.
7) When lodging, move the auxiliary hook (90) to the arm (87a)

), when the stand (94) is removed from the planting part (
15).

By the way, the bumper (76) is formed in a curved part (76al) with the tip side bent downward, and the bumper frame (
77) is folded and stored, the fertilizer tank (9) of the outermost side row fertilizer application device (34) installed in the planting section (15)
The lower part of the roll case (96), which is connected to the roll case (96), is surrounded from the outside by the curved part (76al) to ensure its safety.

In addition, the split seedling carrier (16al) and the seedling carrier main body (16al) are also included.
The surface of the seedling stand (16) is colored in a different color so that the folded portion of the seedling stand (16) and the folding status can be easily and reliably confirmed.

The present embodiment is configured as described above, and the folding operation of the left and right divided seedling carriers f16al will be described below.

As shown in FIGS. 5 and 6, when the seedling carrier (16al) is combined, the first arm (37), which is in the lower vertical position, is driven by the motor (43), and when the wire f52al (52bl) is loosened, the gas spring (53), rotate the seedling support body (16al) outward by approximately 90 degrees about the first fulcrum shaft (36), and move the seedling support body (16al) to the central seedling support body
6b) It is pulled outward and pulled upward. Then, when the first arm (37) rotates approximately 90 degrees and the upper and lower second fulcrum shafts (38) overlap on one vertical line (R), the seedling carrier (1
