Description

[Detailed description of the invention] The present invention has a separate configuration of a seedling receiving plate member that receives mat seedlings corresponding to a unit planting row and a partition member located between adjacent seedling receiving plate members, and The members can be freely inserted and extracted from the lateral direction via the slit-shaped engagement groove and the engagement protrusion, and can be fixedly connected in a continuous state via a horizontal stay placed on the lower surface of the members. Regarding the structure of a seedling stand for a certain rice transplanter.

In the seedling mounting table structure of such a rice transplanter, seedling receiving plate members and partition members of the same shape are mass-produced, and a number of seedling receiving plate members equal to the desired number of planting rows and one less than this number are prepared. By sequentially engaging the partition member through the retaining groove and the engaging protrusion, and fixedly connecting them in a continuous state through the stay, it is possible to economically create seedling stands with various numbers of planting rows. It can be configured to be advantageous.

However, if this type of device simply engages and connects both types of members, a step will occur on the seedling placement surface at the engagement part between the engagement groove and the engagement protrusion, and as a result, the seedlings on the placement mat will also be affected. A difference in level occurs at both ends, which causes variation in the amount of seedlings taken out.

Therefore, conventionally, a method has been taken in which the joining side edges of both types of members are brought into butt contact with each other in a position near the seedling take-out port, with their upper surfaces being flush with each other. , there is a risk that one of the butt ends may float up, and if such a butt end floats up, a new level difference will occur in the mounting mat seedlings.To avoid this,
This eliminates the need for tedious assembly work such as fixing the abutting ends of both types of members to the horizontal stays, but this has the desired effect of allowing a seedling stand with any number of rows to be constructed easily and economically. This was the cause of the decrease.

In view of the above points, the present invention minimizes the number of assembly steps required, and at the same time, does not create a step at the seedling outlet, nor does the side surface rise, and is fixedly connected to the soil surface. The purpose is to try to make things possible.

The seedling stand structure of the rice transplanter according to the present invention has the above-mentioned structure, and the upper surfaces of the two types of members are located flush with the joining side of the two types of members in the vicinity of the seedling take-out port. The present invention is characterized in that a member having step portions that overlap each other vertically and having the step portion located at the upper part of the overlapping portion is provided with a fixing portion for the horizontal stay.

That is, since the joint side edges of both types of members are joined with the stepped portion so that their upper surfaces are flush, one of the members on the side having the stepped portion located at the upper part in the overlapping portion is joined horizontally. By simply fixing it to the stay, the other member can also be pressed and fixed to the horizontal stay.

In this way, by simply fixing one member to the side stay, both types of members can be securely attached to the side stay without creating a step at the joint and without raising the sides. Therefore, it has become possible to facilitate assembly with a constant planting amount.

Hereinafter, an embodiment of the present invention will be described based on the drawings. As shown in FIG. The structure of the seedling platform C is equipped to be reciprocally movable in the lateral direction with respect to the direction of movement of the aircraft, and is capable of sending out seedlings downward on an incline, and corresponds to a unit planting row, as shown in Figure 2 and below. A seedling receiving plate member 1 for receiving mat seedlings a, a partition member 2 having a diagonal opening with a downward opening located between adjacent seedling receiving plate members 1, and a seedling receiving plate member 1 located on both sides of the mat. , a downward opening located along the outer side of 1.

The side frame members 2A, 2A having a cylindrical shape are divided, and the seedling receiving plate member 1 and the partition member 2 are connected to each other by a lateral opening slit-like engagement groove 3 on the side of the seedling receiving plate member 1. The seedling receiving plate member 1 and the side frame member 2A also have the slit shape. These three types of members 1.2.
2A can be fixedly connected in a series through horizontal stays 5 attached to their lower surfaces at three locations in the direction of sending out seedlings, thereby creating a number of seedling receiving plates equal to the desired number of planting rows. A member 1, one less partition member 2, two side frame members 2A, 2A, and three horizontal stays 5.
. . . The seedling mounting table C is configured to have a desired number of planting rows.

Note that the engagement groove 3 is located at the side portion of the seedling receiving plate member 1, and
By integrally connecting the L-shaped members 1a at the locations spaced apart in the direction of sending out the seedlings, the engaging protrusions 4, 4A
The engaging protrusions 4, 4A are arranged in a state in which the engaging portions of the partition member 2 and the side frame member 2A, which are continuous in the seedling sending direction, are shaped intermittently in the seedling sending direction. It is attacked from the side.

Further, the partition member 2 and the side frame member 2A are the same member.

Furthermore, the seedling receiving plate member 1 is provided with holes 1b for allowing the rotary forced seedling sending device E disposed on the lower surface of the seedling platform C to act on the lower surface of the soil of the seedling bed. be.

The joining side portion of the seedling receiving plate member 1 and the partition member at a position near the seedling take-out opening formed on the rail D that slidably supports the lower end of the seedling mounting table C and the seedling placing mat seedling a. 2
The member ( The drawing shows a partition member.

) 2 side is formed with a hole 7 (an example of a fixing part) for fixing the screw 8 to the horizontal stay 5, so that by fixing the partition member 2 to the horizontal stay 5, the seedling receiving plate member 1 can be stepped. Part 6, 6
It is designed to be fixed to the horizontal stay 5 via '.

The seedling receiving plate member 1 and the partition member 2 are designed to have the same thickness, and the stepped portions 6 and 6' are designed to overlap vertically within the thickness of both types of members 1 and 2. , the plate thickness is half that of the members 6 and 6'.

Also, at the joint side portion between the seedling receiving plate member 1 and the side frame member 2A,
The same stepped portions 6, 6' as described above are used.
