[Detailed description of the invention] [Industrial application field]

The present invention relates to a soil block manufacturing apparatus used for sowing and growing seeds such as rape seedlings.

[Conventional technology]

As a conventionally well-known soil block machine, it is equipped with a pressurizing device that supplies adjusted bed soil to approximately a predetermined thickness onto an intermittent moving belt, compacts the moving bed soil in a line in the width direction, and A machine that continuously forms soil blocks is equipped with a cutting device that cuts the bed soil to a predetermined size and a punch that punches seeding holes in the cut blocks.
For example, it is disclosed in Japanese Patent Publication No. 54-33972.

[Problems to be solved by the invention]

The above-mentioned conventional soil block machine has the advantage of being able to continuously and efficiently manufacture soil blocks, but the equipment has become larger and the soil block machine has the advantage of being able to produce soil blocks continuously and efficiently. The soil is compressed in rows in multiple units, cut, and drilled with holes for seeding. Therefore, for example, when a group of manufactured soil blocks is placed in a seedling box, the shape, degree of compaction, and There was a problem in that the water content of the goldstone was uneven, causing variations in seed germination and seedling growth.

[Means to solve and cover the problem]

In order to solve the above-mentioned problems, the present invention provides a soil filling device that stores a substantially predetermined amount of adjusted bed soil in a leveled state in a receiving tray; Inside the casing frame of the size to be inserted, there is a molding part with a large number of partition cutting blades installed to cut the bed soil into soil blocks of the desired size, and a molding part with a large number of partition cutting blades installed above the bamboo casing frame. A plunger part that is provided to be movable up and down and includes a group of plungers that are fitted into the compartments of each of the partition cutting blades and have the functions of compressing bed soil stored in the partitions, forming seeding holes, and discharging soil blocks. The present invention is characterized in that the tray is movable to the bottom of the soil filling device and to the bottom of the molding, and also comprises a seedling box that can be moved from the opposite side to the bottom of the molding.

[Function 1] With the above configuration, it is possible to miniaturize the device, and it is also possible to form a group of soil blocks for one seedling box at a time, so a uniform group of soil blocks can be obtained, and the seeding hole is small. Since it is formed at the same time as compaction, it is possible to reliably make a hole in the center of the top surface of the soil block, allowing the soil block to contain high moisture content, and furthermore, it is possible to continuously fill the soil into the saucer and move it downwards. Furthermore, it is possible to automatically refill the molded soil block group into the seedling raising box. [Embodiment] An embodiment of the present invention will be described below with reference to the drawings. In FIGS. 1 and 2, reference numeral 1 denotes a base of the soil block manufacturing apparatus, which has a rectangular planar shape, and cylindrical guide branches 2 are erected at the four corners of this base 1. . An upper frame 3 is fixed to the tops of the four guide columns 2. This upper frame 3 stably supports the guide column 2, and also has a bracket 3 in the center of its plane.
The cylinder U portion of the hydraulic cylinder 4 is supported downward via a. The upper ends of a pair of diamond-shaped central frames 5 are connected to the tip of the piston of the hydraulic cylinder 4, and the upper ends of a pair of triangular side frames 6 are fixed to both side ends of the central frame 5. This side frame 6.6
A casing frame 8 of the molded part 7 is fixed to the lower part of the molded part 7. The casing frame 8 of the molding section 7 has a rectangular planar shape, and the size almost matches the inner edge of the seedling box, which will be described later. A sliding ring 9 is attached to the four corners of the casing frame 8 so as to be able to move around the guide column 2 by being inserted through the guide column 2, and to move up and down along the guide column 2 as the hydraulic cylinder 4 expands and contracts. It has become. As shown in Fig. 3, the inside of the casing frame 8 is divided into four equal parts in the length direction and into two equal parts in the width direction, and is sized so that each of the eight divisions forms a square of the same size in plan. Partition frame 1
The casing frame 8 also serves as this large partition frame, and the lower end of each large partition frame 10 has a cutting blade 10a having a cutting edge on the inside. Inside the large partition frame 10, there are further small partitions 11 arranged into equally spaced squares.
A double-edged cutting blade 11a is formed at the lower end. Furthermore, the difference in length between the large partition frame 10 and the small partitions 11 is such that the large partition frame 10 is longer by 1 to 21111 points. A piston tip of a hydraulic cylinder 12 for the plunger 11 is attached to the lower end of the central frame 5, and the base of the cylinder is attached to a plunger frame 13 forming a plunger portion. The plunger frame 13 has a sliding ring 14 similar to the sliding ring 9 of the molding part 7, and moves up and down along the guide column 2 by the expansion and contraction of the hydraulic cylinder 12. A large number of plungers 15 that can be raised and lowered from the top of each rectangular parallelepiped space partitioned by the large partition frame 10 and the small partitions 11 are installed, and these plungers 15 are used to compress the bed soil, form seeding holes, and form soil blocks. The extrusion function is fT. A saucer 1G is provided on the base 1 below the molding section 7 so as to be removable. This saucer 16 has a width that is almost equal to the width of the casing frame 8, and a length that is rectangular in plan due to the quality of the casing frame 8. It is placed in an even shape. In the saucer 1G, bed soil kneaded by a soil mixer is placed in a predetermined amount by a bed soil filling device 17 and leveled.
A seedling box support stand 19 for supporting the seedling box is provided. When the saucer 1G is positioned below the bed soil filling device 17, the seedling box 18 placed on the seedling box support stand 19 is positioned below the casing frame 8 of the molding section 7 raised by the hydraulic cylinder 4. That's what I do. In the soil block manufacturing apparatus with such a configuration (first, the saucer 1G is positioned below the bed soil filling device 17,
The bed soil that has been mixed and adjusted with a soil mixer (not shown), etc., and placed in the bed soil filling device 17 is incorporated in a predetermined amount, leveled, and moved onto the 3 machines 1 (below the forming section 7) (Fig. 4 fO ). Next, when the plunger hydraulic cylinder 12 is contracted and the plunger 15 is positioned at the upper end of the space partitioned by the large partition frame 10 and the small partition 11, and the hydraulic cylinder 4 is extended, the forming part 7 and the plunger frame 13 is lowered along the guide column 2, and the casing frame 8.
The lowering of the large partition frame 10 is stopped at the position where the lower end touches the bottom surface of the tray 16, and the floor soil t in the tray 1111B is guided into each partition in the casing frame 8 by the cutting blades 10a and 11a in a bright place. It is housed in a rectangular parallelepiped space (Fig. 4 (b)). Nowadays, in the large partition frame 10, as shown in FIG. The bed soil is evenly cut by force 118 and introduced into the space. With this bed soil stored in the partition space, the plunger hydraulic cylinder 12 is extended and the plunger frame 13 is lowered 1! (Figure 4 (''))
, the bed soil in each partition space is compressed by each plunger 15, and a seeding hole is also formed at the same time. Plunger 1 at this time
5 descent, pressure f! ffi lowers the stored bed soil to approximately half its height, and keeps the hydraulic cylinder 12 at rest. Then, when the hydraulic cylinder 4 is contracted and the forming part 7 is raised, the L is compressed in each partition within the casing frame 8.
The bed soil is raised without leaving almost any bed soil in the Ukuryu 16 (see Figure 4), and the saucer 1G is placed in the bed soil filling device n17.
(Fig. 4, 09). Due to this movement of the saucer 16, the seedling box 18 placed on the seedling box support stand 19 is
Each plunger 1115 is located below the elegant casing frame 8, and by extending the plunger hydraulic cylinder 12, each plunger 1115 simultaneously discharges a group of compressed soil blocks into the seedling growing box 18 (FIG. 4(f)). Then, the seedling box 18 containing the soil block is taken out from the support stand 19 (Fig. 4 (+-)), the seeds are sown in the seeding holes, and the seeds are stocked in the germinator to germinate and grow. Repeat this process. In the above embodiment, 20Q soil blocks can be manufactured in -U, but by changing the size of the partition and the plunger, soil blocks of desired size and number can be manufactured. In addition, conventional soil block machines had a limit of about 70% moisture in the bed soil, but with this example, 80% can be achieved, which is convenient for seed germination and seedling growth. Good. Since the length of the large partition frame 10 is slightly longer than the length of the small partition 11, the amount of bed soil stored in each small partition space within the large partition frame is averaged, and when lifted from the tray, The holding power of the floor soil by the large partition frame 10 is strengthened and the compressed soil blocks are prevented from falling. Furthermore, the soil block can be transferred to the seedling raising box simply by pushing out the plunger 1715. Effect 1 of the invention As explained below, the soil block 31 of the present invention
According to 'li E, it is possible to continuously fill the soil into the saucer and move it to the molding section, and also to mold a large number of soil blocks to be accommodated in the first seedling at once.
It is possible to produce uniformly compacted soil blocks. It also ensures that the seeding hole is formed in a fixed position, giving good results to the sown seeds. It is possible to manufacture soil blocks even if the moisture content of the bed soil is increased, which has a positive effect on seed germination and seedling growth. The molded soil block group can be automatically transferred to the seedling box, which improves work efficiency and eliminates the need to invert the soil blocks.Furthermore, the device can be made more compact.
