Description

[Detailed explanation of the idea] [Industrial application field]

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

[Prior Art] A well-known soil block machine is a pressurizing device that supplies adjusted bed soil to approximately a predetermined thickness onto an intermittent moving belt and compacts the moving bed soil in a line in the width direction. For example, in 1977, a machine that continuously formed soil blocks was equipped with a cutting device that cut the compacted bed soil into a predetermined size, and a punch that punched holes for seeding in the cut blocks. -Disclosed in Publication No. 33972.

[Problem that the invention attempts to solve]

In the conventional soil block machine,
Although it has the advantage of being able to produce soil blocks continuously and efficiently, it requires larger equipment, and the soil block compresses and cuts the bed soil supplied on a belt in multiple horizontal rows. Since seeding holes are drilled, for example, when a group of manufactured soil blocks is placed in a seedling box, the shape, degree of compaction, moisture content, etc. of the individual soil blocks may be uneven.
There was a problem that caused variations in seed germination and seedling growth.

[Means to solve the problem]

In order to solve the above-mentioned problems, the present invention includes a saucer that accommodates a predetermined amount of adjusted bed soil in a leveled state;
A casing frame that is sized to fit into a saucer includes a molded part that has a number of partitions that divide the bed soil into soil blocks of desired size, and a molded part that is movable up and down above the casing frame. a plunger section provided with a group of plungers having functions of compressing bed soil, forming seeding holes, and discharging soil blocks that are fitted into the sections of each of the partitions and housed in the partitions; It is divided into equal parts by a large partition frame, and the inside of the large partition frame is further divided into equal parts by small partitions, and the length of the lower end of both partitions is slightly longer than that of the large partition frame, and the inside of the lower end is It is characterized by having a cutting blade that is inclined towards.

[Effect]

With the above configuration, it is possible to miniaturize the device, and also to form a group of soil blocks for one seedling box at a time, so that a uniform group of soil blocks can be obtained. Because they are formed at the same time, it is possible to reliably make a hole in the center of the upper surface of the soil block, and the bed soil is not cut while being guided inside the large partition frame, and there is no shortage of bed soil in the surrounding area, and it is sufficiently compacted. Soil blocks of a predetermined size are obtained, the soil blocks can contain high moisture content, and the molded soil blocks can be automatically refilled into seedling boxes.

【Example】

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 columns 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. The upper frame 3 stably supports the guide column 2, and the cylinder base of the hydraulic cylinder 4 is supported downwardly at the center of its plane via a bracket 3a. 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. A casing frame 8 of the molded part 7 is fixed to the lower part of the side frames 6, 6. 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. Sliding rings 9 are attached to the four corners of the casing frame 8 so that they can be slid through the guide columns 2, and can be moved up and down along the guide columns 2 by expansion and contraction of the hydraulic cylinders 4. ing. 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. It is partitioned by a partition frame 10, and 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. The inside of the large partition frame 10 is further partitioned into squares at equal intervals by small partitions 11, and a double-edged cutting blade 11a is formed at the lower end thereof. Also,
The difference l between the lengths of the large partition frame 10 and the small partitions 11 is such that the large partition frame 10 is 1 to 2 mm longer. A piston tip of a plunger hydraulic cylinder 12 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 upper part of each rectangular parallelepiped space partitioned by the large partition frame 10 and the small partitions 11.
This plunger 15 has the functions of compressing the bed soil, forming seeding holes, and pushing out the soil block. A saucer 16 is provided on the base 1 below the molding section 7 so as to be removable. This saucer 16
has a rectangular planar shape, the width of which is approximately equal to the width of the casing frame 8, and the length of which is slightly longer than the length of the casing frame 8, into which a predetermined amount of bed soil is leveled to a predetermined thickness. It is to be put in the form. A predetermined amount of bed soil kneaded by a soil mixer is poured into the tray 16 by a bed soil filling device 17 and leveled, and a seedling raising box 18 is supported at one longitudinal end of the tray 16. Seedling box support stand 1
9 is provided. When the saucer 16 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. It is designed to do so. In the soil block manufacturing apparatus having such a configuration, first, the saucer 16 is positioned below the bed soil filling device 17, and the bed soil, which has been mixed and adjusted with a soil mixer (not shown) and put into the bed soil filling device 17, is placed in a place. Pour a certain amount, level it out, and place it on the base 1 below the molding part 7.
Move it up (Figure 4 A). Next, the plunger hydraulic cylinder 12 is contracted and the plunger 15 is
When the hydraulic cylinder 4 is extended while being positioned at the upper end of the space partitioned by the large partition frame 10 and the small partition 11, the molding part 7 and the plunger frame 13 descend 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 saucer 16, and the bed soil of the saucer 16 is cut and guided into each partition in the casing frame 8 by the cutting blades 10a, 11a. It is housed in a rectangular parallelepiped space (Fig. 4b). At this time, in the large partition frame 10, as shown in FIG. 3, the cutting blade 10a guides the bed soil into the space within the partition while cutting it, resolving the insufficient introduction of bed soil in the peripheral area, and in the small partition 11, the cutting blade 11a Cut the bed soil evenly and introduce it 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 (FIG. 4C), the bed soil in each partition space is compressed by each plunger 15, and a seeding hole is also formed at the same time.
At this time, the amount of descent and compression of the plunger 15 is such that the height of the accommodated bed soil is approximately half, and the extension of the hydraulic cylinder 12 is stopped. Then, the hydraulic cylinder 4 is contracted to form the molding part 7.
When the casing frame 8 is raised, the compressed bed soil for each partition is lifted without leaving almost any bed soil in the saucer 16 (Fig. 4 D),
6 to the bed soil filling device 17 side (Fig. 4 E). By this movement of the tray 16, the seedling box 18 placed on the seedling box support stand 19 is positioned below the raised casing frame 8, and by extending the plunger hydraulic cylinder 12, each plunger 15 is compressed. The soil blocks thus prepared are simultaneously discharged into the seedling nursery box 18 (FIG. 4). and,
The seedling box 18 containing soil blocks is placed on the support stand 1.
9 (Fig. 4, G), sow the seeds in the seeding hole, stock them in a sprouter, and germinate and grow them. Repeat this kind of work. In the above embodiment, 200 soil blocks can be manufactured at one time, but by changing the size of the partition and the plunger, soil blocks of desired size and number can be manufactured. In addition, the moisture content of the bed soil was limited to about 70% with conventional soil block machines, but with this example, it is possible to reduce the moisture content to 80%, which is convenient for seed germination and seedling growth. . Large partition frame 10
Since the length is made slightly longer than the length of the small partition 11, the amount of soil stored in each small partition space within the large partition frame is averaged, and when lifted from the tray, the large partition frame 10 This strengthens the holding power of the bed soil and prevents the compressed soil blocks from falling. Furthermore, the soil block can be transferred to the seedling growing box simply by pushing out the plunger 15.

[Effect of the idea]

As explained above, according to the soil block manufacturing apparatus of the present invention, a large number of soil block groups accommodated in one seedling box, for example, can be molded at once, and in particular, the bed soil near the large partition frame can be molded. The cutting blade guides the soil inward so that there is no shortage of bed soil.
Sufficient compression force can be obtained and uniformly compressed soil blocks can be produced. Also, the seeding hole is reliably formed in a fixed position, giving good results to the sown seeds. It is possible to produce 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 easily transferred to a seedling nursery box, work is made more efficient, and the soil blocks are not damaged. Furthermore, miniaturization of the device is achieved.
