Description

[Detailed Description of the Invention] The present invention relates to a side marker mechanism that also serves as a side marker in a walk-behind rice transplanter.

In other words, it can be effectively used as a streak marker on rice fields with little water, and this streak marker can also be used as a side marker when there is a lot of water. Although the disclosed technology is already known, this known technology is a marker that is used as a side marker by moving the machine so that the tip of the marker is in line with the planted seedlings. As a result, it is not easy to check the degree of agreement between the direction of movement of the machine and the direction of the existing seedling rows, and therefore, it is difficult to align rows after the direction of movement of the machine has changed significantly, such as when aligning rows after turning the machine at the edge of the field. This method had the disadvantage that it could not be performed immediately.

The invention of the present application was made to solve these problems, and can be selectively used for line citations and side markers, and can be installed and changed to the side bumper, resulting in a compact structure.
Moreover, the function as a side marker has been improved,
It is provided to enable suitable implementation.

Next, the embodiment shown in the drawings will be described. FIG. 1 shows a side view of a walk-behind six-row rice transplanter, with a center float 5 that is long in the front-rear direction between both wheels 2 and 2', and both side floats 5 that are short in the front-rear direction on the outside. An engine 6, etc. is installed above the front part of the center float 5, and a center marker 7 is installed upright above the front part of the engine 6 at the center of the width direction of the entire aircraft. Above the rear side of the float 5 is a handle 8,
8 is extended, and in front of the handles 8, 8 is a laterally long seedling stand 9 on which six pine seedlings are respectively placed.
is installed diagonally, and a seedling loading stand 9 is placed along the lower seedling taking out stand 10.
Each float 5, 5',
A total of six planting claws 4 extending upward on both sides of the seedling tray 5' are constructed in the same manner as the conventional type so that six rows of seedlings can be planted by scraping off the block seedlings from the seedling take-out stand 10, respectively.

In addition, on both sides of the planting area which widens to the outside of both wheels 2, 2' and to the outside of both side floats 5', 5', both side bumpers 1, which are formed by bending a pipe into a U-shape in a plane, are installed. 1' is installed in a protruding manner on both sides, upper and lower supports 11, 11' are inserted into both side bumpers 1, 1', and are removably attached with bolts 12. 11' is equipped with a line citation marker mechanism to be described later. That is,
The streak quotation marker mechanism is composed of a marker body a made of rod that partially immerses into the field and forms streaks on the field surface as the machine advances, and a linear support rod A that supports the marker body a. , the support rod A is support rod 1
Another support rod 14' is attached to the tube metal 13 fixed to the tip of 4.
The base portion of the marker member 14 is formed so that it can be rotated 180 degrees to be fitted and fixed by a set bolt 15, and the marker body a is provided vertically at the tip of the support rod 14'.

The base of the support rod 14 is connected to the protrusion 1 on the support metal 11.
7 and 17 via pins 18, and the support metal 11
The tip of the inner wire 19 extending from the top of the support rod 12 is connected to the protruding piece 20 in the middle of the support rod 12, and the inner wire 19' and the outer wire 19' are extended to the operating part (not shown) on the handle 8, 8 side. Configure it for operation.

In addition, by fixing the supports 11, 11' to the fore-and-aft rod portions of both side bumpers with bolts 12, the support rod A can be extended in the lateral direction of the aircraft, and further by fixing the supports 11, 11' to the lateral rod portions of both side bumpers with bolts 12, the support rod A can be extended in a direction along the fore-and-aft direction of the aircraft, and by changing the mounting position of the supports 11, 11', the direction of the streak reference marker mechanism can be changed.

Although the length of the support rod A is short in the drawing, it is actually long.

However, if there is little water during planting, as shown in Figures 2 to 4, align the supports 11, 11' with the longitudinal rods on the sides of both side bumpers 1, 1'. When the support rod A is attached so that it can extend in the lateral direction of the machine body, the unplanted surface can be marked with a streak 16 by the marker body A as the machine moves forward.
When the aircraft changes direction and plants adjacent to each other, the center marker 7 can be aligned with the line 16 and moved forward as a mark, and when the aircraft turns, the inner wire 19 is pulled, as shown by the imaginary line in Fig. 4. It is also possible to turn with the support rod A erected in the state shown in FIG. 1 so that it does not get in the way.

Also, if there is a lot of water on the rice field, it will be difficult to make streaks as described above, and in such a case, loosen the bolts 12 and remove the supports 11, 11', and remove the front of both side bumpers 1, 1'. The support rods 11 and 11' are aligned and fixed to the outer ends of the transverse rod portions, so that the support rod A extends in the front-rear direction, and the set bolt 15 is loosened to rotate the support rod 14' by 180 degrees. When the marker body A is fixed with the set bolt 15, it can be installed and changed as shown in Figs. It can be driven straight.

In this way, the invention of the present application has streak reference marker bodies that are partially immersed in the field and form streaks on the field surface as the machine advances. , A line quotation marker mechanism consisting of a linear support rod that supports the marker body is installed so as to extend in the lateral direction of the fuselage, and the marker mechanism is installed by changing the direction so that it follows the longitudinal direction of the fuselage. Because it is configured to be changeable, it can be effectively used as a line marker on rice fields with little water, and can also be used as a side marker when there is a lot of water, allowing one marker mechanism to be selected as both a line marker and a side marker. It can be used for various purposes, and can be attached to the side bumper to create a compact structure.
Moreover, in order to use the marker mechanism as a side marker, the support rod of the marker mechanism is configured to be able to be attached and changed by changing the direction of the support rod so that it follows the front and rear directions of the fuselage. By changing the direction so that it follows the front and back direction of the machine, you can instantly check the degree of coincidence between the machine's traveling direction and the direction of the already planted seedling row, as well as the distance between the two, and check the conditions after the machine turns at the edge of the field. It has the feature that alignment can be performed immediately after a major change in the direction of travel of the aircraft during alignment, and the function as a side marker is improved and can be carried out suitably.
