Description

[Detailed description of the invention] [Industrial application field] This invention relates to a seedling transplanter.

[Prior art]

As this type of conventional technology, Japanese Patent Application Laid-open No. 56-144017
As shown in the publication, the lower part is connected, the upper part is separated into individual plants, and the seedlings are grown in a seedling container with holes in the top surface, and the seedlings are grown through the holes in the top surface, and the seedlings are transplanted as they are to the field. It is a container for raising seedlings.

[Problem that the invention seeks to solve]

However, the above-mentioned conventional method is disclosed in Japanese Patent Application Laid-Open No.
As shown in Figure 7 of Publication No. 144017, a seedling raising container containing a large number of seedlings connected together is transplanted into the field as is, and the seedlings are not separated one by one and transplanted using a transplanter.

[Means to solve the problem]

In order to solve the above-mentioned problems, this invention uses a seedling grower 5 in which the lower part is connected, the upper part is separated into individual plants, and the upper part has a hole 6. A seedling stand 7 on which the whole seedling raising device 5 can be placed;
A seedling transfer device 8 that transfers the seedlings on the seedling platform 7 together with the seedling tray 5 toward one side of the seedling platform 7, and a seedling device that transfers the seedlings transferred by the seedling transfer device 8 one by one into a seedling device. This is a transplanting machine characterized by being equipped with a seedling planting device 9 for separating each seedling seedling and planting it in a field.

[Function and effect of the invention]

According to this invention, the seedlings are grown by sprouting from the holes 6 on the top surface in the seedling grower 5, which has the lower part connected and the upper part separated into individual plants with holes 6 on the top surface. Each plant is lined up at a predetermined pitch, and the seedlings are placed on the seedling stand 7 along with the seedling raising device 5, and the seedlings on the seedling placing table 7 are transferred to the seedling raising device 5 using the seedling transfer device 8.
The seedlings are transferred to one side of the seedling platform 7, and the seedlings transferred by the seedling planting device 9 can be separated from each other and planted in the field with the seedling tray 5. The seedlings wrapped in the container 5 are transferred to the seedling planting device 9 accurately and with little damage, and are accurately transplanted to the field. Since the seedlings are transplanted one by one wrapped in the seedling grower 5 and accurately with little damage, their growth after transplantation is very good.

〔Example〕

A transplanter which is an embodiment of the present invention will be described in detail based on the drawings.

First, the seedling-raising frame 3 is constructed by molding a synthetic resin material to frame the side wall frame 1, and has a large number of seedling-raising holes 2 extending vertically through the frame.

Next, the seedling raising device 5 uses a material that easily rots in the soil (for example, paper material), and forms a continuous row of seedling raising holes 4 . A germination hole 6 is provided above each seedling growing hole 4.

Then, after placing the seedling raising device 5 on the seedling raising frame 3 and filling the seedling raising hole 4 with bed soil, sowing and raising the seedlings will produce one seedling each, as shown in Fig. 1. Seedlings sprout from the germination hole 6 of each seedling raising hole 4 and grow.

Next, I will explain the main parts of the transplant machine.
A seedling transplanting unit is constituted by a seedling platform 7 around which a conveyor belt 8 as a seedling transfer device is wound, and a seedling planting device 9 provided at one end of the seedling platform 7. At the seedling separation position of the seedling platform 7 where the seedlings are separated one by one, there is provided an opening/closing receiving plate 10 whose tip part receives the lower surface of the seedlings to be separated.
It is configured to open and close in conjunction with 1. The seedling planting device 9 also includes a cutting blade 11 that cuts the leading edge of the seedlings transferred by the conveyor belt 8 into individual plants, and a cutting blade 11 that receives the seedlings separated into individual plants. It is composed of a transplanting tool 12 for planting seedlings in a field.

As described above, the grown seedlings are removed from the seedling raising frame 3 along with the seedling raising device 5, and are placed on the conveyor belt 8 as a seedling transfer device of the seedling table 7 of the transplanter as shown in FIG. Ru. When the seedlings are transported together with the seedling grower 5 to the cutting position by the conveyor belt 8, they are sequentially cut by the cutting blades 9 that rotate from above at a constant timing, and after cutting, the seedlings are opened and closed. The plate 10 is opened downward, and one seedling is put into the transplanting tool 12 and transplanted to the field by the transplanting tool 12.

In such a transplanting process, since the seedlings are kept in succession in the seedling grower 5, the seedlings can be transported to the transplanting position on the transplanter very reliably.

Moreover, since the seedlings are wrapped in the seedling raising device 5, the transplanting work can be carried out smoothly without causing much collapse on the floor until the transplanting into the soil is completed. Since the seedlings are transplanted one by one wrapped in the seedling grower 5 and accurately with little damage, their growth after transplantation is very good.

[Brief explanation of the drawing]

The drawings show an embodiment of the present invention; FIG. 1 is a sectional view showing a seedling-raising state, and FIG. 2 is a side view of the main parts. In the figure, numeral 5 is a seedling raising device, 6 is a hole, 7 is a seedling stand,
Reference numeral 8 indicates a seedling transfer device, and 9 indicates a seedling planting device.

[Claims]

1. A ground sensor 5 that moves up and down as the planting device 4 moves up and down, and in conjunction with the detection operation of this sensor 5, the planting device 4 maintains its height relative to the mud within a set range. In the rice transplanter, the rice transplanter is equipped with a mechanism 6 that is driven to move up and down so as to move up and down, and an operation mechanism 16 that reduces the sensing load of the sensor 5, and a state in which the drive up and down mechanism 6 restrains the descent of the planting device, and a state in which the restraint is released. This rice transplanter is characterized by being provided with a mechanism 17 that can be freely switched between. 2. The rice transplanter according to claim 1, wherein the check mechanism 17 reversibly switches to the check state in conjunction with the decreasing operation of the operating mechanism 16.
