Description

[Detailed description of the invention] Industrial application field This invention is a highly accurate pot seedling box that can intensively sow small and highly elastic vegetable seeds, etc., mainly in the center of the seedling chamber of the pot seedling box. Regarding seeding machines.

BACKGROUND ART As a conventional device of this kind, there is a "seedling machine for seedling boxes" disclosed in Japanese Utility Model Application Publication No. 15317/1983 filed by the present applicant.

This conventional seeding machine will be explained with reference to FIG. 5. A seedling box feeding table 1 is formed so as to be able to transport flexible seedling boxes a each having a plurality of pot seedling chambers b arranged in series. A seed tank 2 is provided above the seedling box feed stand 1, and a seeding roll 3 is rotatably abutted on the bottom opening of the seed tank 2.
A large number of sowing holes 4, 4, . . . for pumping out seeds from the seed tank 2 are arranged on the circumferential surface of the sowing roll 3. A driving roll 5 is provided at the front of the seed tank 2, and a seed pressing roll 9 is arranged at the rear. The drive roll 5 is provided with a soil presser protrusion 7 that can freely engage with the seedling chamber b of the seedling box a.
This soil pressing protrusion 7 compresses the bed soil in the seedling room b and makes a depression in its surface to form a seed hole for paddy rice.

Problems to be solved by the invention As mentioned above, the seed hole for rice is
Although it is formed by the retaining protrusions 7 on the circumferential surface, it easily collapses due to insufficient compression. However, seed rice is large, heavy, and has no elasticity, so even if the seed pore is slightly collapsed, it will remain at the drop point and can be sown without trouble. However, small, elastic seeds like onions have the disadvantage that if the seed pores are collapsed, they bounce and scatter irregularly, resulting in uneven germination.

Means to Solve the Problem This device is an improvement on the conventional seedling box seeding machine, and is capable of sowing small and highly elastic seeds such as onions in a concentrated manner in the center of the nursery room, allowing for highly accurate pot seedlings. The purpose is to provide a box seeding machine.

That is, this invention is based on the idea that pot seedling boxes, which are made up of pot seedling rooms arranged in a grid pattern, are placed on a seedling box feeder that can be freely transported.
A driving roll having a soil presser protrusion that can freely engage with the pot seedling chamber, a sowing roll for sowing a fixed amount of seeds from the seed tank into the nursery chamber, and a seed presser roll for compressing the seeds are arranged. In the seeding box seeding machine, a seed hole forming roll is arranged between the drive roll and the seeding roll, and the roll has a
The gist of the present invention is a structure of a seeding machine for a pot seedling box, characterized in that molded protrusions that can freely engage with the pot seedling chamber are provided, and these protrusions are formed in a tapered manner.

Function Since this device is constructed as described above,
Place a potted seedling box filled with bedding soil in the seedling chamber on the top of the seedling box feeder, engage the soil presser protrusion of the drive roll with the seedling chamber of the seedling box, and then drive the drive roll. The bed soil is sent to the seed hole forming roll while being compressed by the soil retaining protrusion. In the seed hole forming roll, the forming protrusions on the peripheral surface are press-fitted into the bed soil to form a mortar-shaped seed hole that is strong and does not lose its shape. When the seeds in the seed tank are sown in a fixed amount into the seed hole, the seeds flow down the slope of the mortar-shaped seedling chamber and are sown in a concentrated manner at the bottom of the seedling chamber.

Embodiment The present invention will be described with reference to an illustrated embodiment. Reference numeral 1 denotes a seedling box feeding stand, on which a seedling box a is movably mounted. As shown in FIG. 3, the seedling box a has a large number of seedling chambers b arranged in a grid pattern, and is formed so as to be curved as a whole. 2 is a seed tank;
It is supported above the seedling box feed stand 1, and a seeding roll 3 is rotatably provided in contact with the bottom opening thereof. A large number of seeding holes 4 corresponding to the seedling chambers b of the seedling box a are arranged on the circumferential surface of this seeding roll 3. 5 is a drive roll, and 6 is a seed hole forming roll, which are provided in front of the seed tank 2 and parallel to the seeding roll 3. A soil retaining projection 7 and a forming projection 8 are provided on the peripheral surfaces of the driving roll 5 and the seed hole forming roll 6. Further, a seed presser roll 9 is provided at the rear of the seed tank 2, and a seed presser protrusion 10 is arranged on the peripheral surface.
Each protrusion 7 provided on these rolls 5, 6, 9,
8 and 10 are arranged radially so as to be able to freely engage with the seedling chamber b of the seedling box a, and the molded protrusion 8 is the fourth
As shown in the figure, the tip is tapered.

To explain the function of this embodiment, the seedling room b
When the seedling box a filled with bed soil is placed on the seedling box feed stand 1, the seedling chamber b at the tip is engaged with the soil presser protrusion 7, and then the drive roll 5 is driven, the soil presser protrusion 7 moves into the seedling chamber b. The seedling box a is transferred to the seed hole forming roll 6 while appropriately compressing the bed soil inside. In the seed hole forming roll 6, the forming protrusion 8 press-fits into the bed soil of the seedling chamber b pressed by the soil presser projection 7 of the drive roll 5, and a mortar shape that is sturdy and does not lose its shape is formed in the center of the seedling chamber b. This results in the formation of a seed pore. Therefore, the seeds introduced into the seed hole flow down the mortar-shaped side wall and
They will be concentrated in the center of the nursery room.

Effects of the invention As described above, according to the present invention, it is possible to form a mortar-shaped seed hole that is strong and does not easily lose its shape in the bed soil in the nursery room, so that the seeds placed into this seed hole can Since it flows down the slope and reaches the bottom of the seed hole, even small and highly elastic seeds can be sown in a concentrated manner in the center of the seedling room.
