[0001]

BACKGROUND OF THE INVENTION 1. Field of the Invention The present invention relates to a structure for holding a seedling mat on a seedling table mounted on a rice transplanter.

[0002]

2. Description of the Related Art Conventionally, a mat holding member for holding a lower surface of a seedling mat is provided on a seedling extracting plate provided at a lower portion of a seedling mounting table, and a main seedling mat pressing body is provided at an upper position of the seedling mat. Things exist.

[0003]

However, in the above-mentioned seedling mounting table, however, in order to hold the seedling mat on the seedling extracting plate from above and below only by the mat holding member and the main seedling mat holding body,
Although the contact surface between the seedling mat and the seedling take-out plate can be partially reduced, the lateral deformation of the seedling mat cannot be prevented. Therefore, when the seedling mat is displaced laterally and both ends of the seedling mat are planted, a lack of stock occurs, and the planting work of the seedlings cannot be carried out smoothly.

[0004]

According to the present invention, a mat holding member for holding a lower surface of a seedling mat is connected to a lower end of a seedling mounting table on which a seedling mat is mounted, and the mat holding member is connected to a seedling. A rice planting plant that is located on the upper surface of the take-out plate, and has a main seedling mat holding body that is provided in parallel with a gap at the lower end of the seedling mounting table so that the upper surface of the seedling mat can be pressed with the main seedling mat holding body. In the seedling mounting table of the rice planting machine, an elastic pressing member for pressing the upper surface of the seedling mat is provided downwardly on the main seedling mat pressing body, and a seedling mat holding structure in the seedling mounting table of the rice transplanter is not provided. It is assumed that.

The present invention is also characterized in that the elastic holding member can be attached to the main seedling mat holding member so as to be vertically adjustable.

[0006]

[Function] In conjunction with the planting operation of the planting claw, the seedling mounting table moves intermittently to the left or right, but at the lower end of the seedling mounting table, the seedling mat is attached to the seedling extracting plate. Slide the top surface sideways. The lower surface of the seedling mat is held by the mat holding member, while the upper surface is pressed by the main seedling mat pressing body and the elastic pressing member.

Therefore, the seedling mat can be moved in the lateral direction while being securely clamped from above and below.

Further, the elastic holding member can be adjusted in the up and down direction and attached, so that the holding pressure can be changed in accordance with the thickness of the seedling mat.

As described above, according to the above embodiment, the mat holding member 74 for holding the lower surface of the seedling mat 75 is connected to the lower end 42-1 of the seedling mounting table 42 for mounting the seedling mat. In addition, the mat holding member 74 is positioned on the upper surface of the seedling take-out plate 72, and a main seedling mat holding member 76 is provided at a lower end portion 42-1 of the seedling mounting table in parallel with an interval, and the main seedling mat is provided. Seedling mat with presser body 76
In the seedling mounting table capable of pressing the upper surface of the seedling mat 75, an elastic pressing member 78 for pressing the upper surface of the seedling mat 75 is downwardly connected to the main seedling mat pressing body 76. Is securely clamped by the mat holding member 74, the main seedling mat pressing body 76 and the elastic pressing member 78, and laterally moves. Then, the lateral displacement of the seedling mat 75 can be reliably prevented.

Therefore, it is possible to prevent a lack of seeds at both left and right end portions of the seedling mat 75, and to prevent the seedling mat 75 from being turned over even when the remaining amount of the seedling mat is small, thereby preventing the seedling from being caught. Is what you can do.

In the prior art, the seedling mat 75 was not traversed by friction with the seedling removal plate 72, and the planted seedlings were set in a dumpling shape and planted. The movement of the seedlings and the removal of the seedlings are reliable, the troubles of the seedlings to be planted do not occur, and the rice transplanting operation can always be efficiently performed.

Further, since the elastic pressing member 78 can be mounted in a vertically adjustable manner, it can be mounted in an optimum state according to the thickness of the seedling mat 75 and the like.
Therefore, the movement of the seedling mat 75 is more reliable, and the seedling planting operation is performed more smoothly.

[0035]

As described above, according to the present invention, a mat holding member for holding the lower side of the seedling mat is connected to the lower end of the seedling mounting table, and the mat holding member is attached to the upper surface of the seedling extracting plate. At the same time, a main seedling mat holding body is provided in parallel at a lower end of the seedling mounting stand at an interval, and the upper surface of the seedling mat can be pressed by the main seedling mat holding body, and Since the elastic holding member that presses the upper surface of the seedling mat is connected to the mat holding body downward, the lower end of the seedling mat is securely held from above and below by the mat holding member and the main seedling mat holding body and the elastic holding member. The lateral movement of the seedling mat can be reliably prevented.

Therefore, even when the right and left ends of the seedling mat are planted, the seedlings can be planted without any lack of stock, and even when the remaining amount of the seedling mat is low, the seedling mat can be planted. Of the seedlings can be prevented, and the entrapment of the seedlings can be eliminated.

In the prior art, the seedling mat was rubbed against the seedling take-out plate and was not laterally fed, and the seedlings were planted in a dumpling-like manner. It does not occur and can always perform rice transplanting efficiently.

Further, by making the elastic holding member adjustable vertically, the elastic holding member can be mounted in an optimum state according to the thickness of the seedling mat, so that the seedling mat can be pressed more reliably.
