Abstract

PURPOSE:To correct deformation of a pot sheet by providing a guide member for preventing the pot sheet from floating in a nursery box near a site for delivering and feeding bed soil of a bed soil feeder. CONSTITUTION:A guide member 13 for preventing a pot sheet 7 in which pot groups having openings for seeding at the tops are arranged crosswise from floating in a nursery box 1 is provided near a site for delivering and feeding bed soil of a bed soil feeder 3. Even if the pot sheet is deformed, the deformation is corrected to a flat shape by pressing the pot sheet against the nursery box with the guide member.

BACKGROUND OF THE INVENTION 1. Field of the Invention The present invention relates to a seeding machine used for growing paper pot seedlings.

0002

[Prior Art] This type of seeding machine is
As disclosed in Publication No. 19520, a paper pot sheet made by integrally molding a group of pots with open tops and narrowed tops arranged vertically and horizontally is loaded into a seedling box, and this seedling box is continuously conveyed. A device is known that is configured to supply bed soil and sow seeds at the same time.

0003

[Problem to be solved by the invention] Since the pot sheet used for growing paper pot seedlings is an integrally molded product of paper material, the pot sheet is likely to warp or deform depending on the degree of moisture absorption. When deformation occurs, the pitch of the openings at the top of each pot becomes misaligned, and the rice seeds may not fit properly into the openings at the top of the pot during the sowing process. Even if the pot sheet is deformed, the present invention can
The purpose is to correct the deformation before the sowing process to ensure proper sowing.

0004

[Means for Solving the Problems] In order to achieve the above object, in the present invention, the seedling box of the pot sheet is placed in the vicinity of the bed soil feeding and supplying part of the bed soil supplying device disposed above the seedling box transport path. The configuration includes a guide member that abuts against and prevents floating inside.

[0005]

[Operation] According to the above structure, even if the pot sheet inside the seedling nursery box is deformed or warped, it is pressed onto the bottom of the seedling nursery box by the guide member and corrected to be flat, and bed soil is supplied in this state. Since the weight of the bed soil acts on the pot sheet, the pot sheet will not warp back even after being separated from the guide member.

[0006]

[Effect of the invention] Therefore, according to the present invention, by utilizing the weight of the bed soil, it is possible to maintain the pot sheet flat and proceed to the next sowing process, so that the pitch of the pot does not shift during the sowing process. It is now possible to properly supply seed rice to each pot.

DESCRIPTION OF THE PREFERRED EMBODIMENTS FIG. 1 shows the overall structure of a seeding machine according to the present invention. This seeding machine includes a bed soil supply device 3, a seeding device 4, a soil covering device 5, and an irrigation device 6 are arranged in this order, and the seedling raising box 1 is configured to be loaded with paper and a pot sheet 7 as shown in FIG. 4 and proceed to each stage. The pot sheet 7 is formed by straining pulp material in a wire mesh mold and dehydrating it under vacuum, and is made up of a large number of pyramid-shaped pots 9 with a narrowed top and a seeding opening 8 formed in the upper end in a vertical and horizontal manner. They are aligned and molded as one piece. When this pot sheet 7 is cut out, the upper end of each pot 9 is closed, and the opening 8 is formed by horizontally cutting the upper end of the pot.

Next, the process of seeding using the above-mentioned seeding machine will be explained. (1) As shown in FIG. 2, the seedling raising box 1 loaded with the pot sheet 7 is first carried into the bed soil supply device 3, and is supplied with bed soil. The bed soil supply device 3 includes a feeding belt 11 and a shutter 12 for adjusting the feeding amount at the bottom of a hopper 10, and the fed bed soil is supplied to the inside of each pot 9 and the joint between the pots in the pot sheet 7. be done. A guide roller 13, which serves as a guide member that presses the upper end surface of the pot sheet 7 downward to correct the warping of the pot sheet 7, is installed at an upper portion of the bed soil supplying portion of the bed soil supplying device 3, and a guide roller 13 is installed at a fulcrum P. Arm 1 pivoted downward at the center
The pot sheet 7 is equipped to be able to move up and down through the pot sheet 4, and the pot sheet 7 advances to the next step without returning to its warp due to the weight of the bed soil. (2) The seedling raising box 1 that has been supplied with bed soil has a rotating brush 15
receives a sweeping and leveling effect. At this time, the upper end of the pot 9 is exposed by several millimeters. (3) Manually load the seeding board 16 from above the seedling raising box 1 from which the bed soil has been swept and leveled. As shown in FIG. 3, this seeding plate 16 is formed with concave guide holes 17 facing the openings 8 of each pot 9 aligned in the pot arrangement. (4) Thereafter, the seedling raising box 1 is vibrated by the vibrator 18 provided on the conveyor line 2, and the bed soil in the box is filled in the pot 9, leading to the next sowing process. (5) In the seeding device 4, as shown in FIG.
Send grain seed rice. (6) After the seeding process, the seeding board 16 is removed and the soil covering process begins. (7) Supply enough soil to cover pot 9, as shown in Figure 5.
Immediately after that, the pressure roller 20 is applied to the top surface of the soil covering, as shown in FIG. By this pressing, even if the seed rice is caught on the edge of the opening 8 of the pot 9, it can be pushed into the opening 8 together with a part of the covering soil. (8) Next, as shown in FIG. 6, use the rotating brush 21 to sweep the surface of the covered soil to remove excess soil so that the seed rice is hidden and the top of the pot 9 is slightly visible. (9) After that, the watering device 6 is used to add 1
Supply approximately 0.8 to 1 liter of water per box, or water containing disinfectant. With the above steps, the seeding process is completed, and the seedling growing box 1 is carried into the germination chamber and begins the growing process.

[0009] In addition to using the guide roller 13 biased downward as described above as a guide member for pressing the pot sheet 7 and correcting the warpage before supplying the bed soil, the pot sheet 7 is elastically pressed at the free end. The guide member can also be constructed of a leaf spring or spring wire supported in a cantilevered manner so as to press the guide member.
