Description

Soil block mixed with biological material and soil block manufacturing equipment

  The present invention relates to a soil block mixed with a biological material such as a seed and a soil block manufacturing apparatus.

Conventionally, various plant cultivation blocks formed so that plants are grown when seeds are mixed in a medium such as soil in advance and water and the like are supplied have been proposed. In general, such a block for plant cultivation blocks the medium by pressing the soil or mixing a large amount of a curing agent (for example, cement or resin material) into the soil.
In addition, a lot of cut grass is generated at golf courses, and a great deal of labor and cost are required for disposal. For this reason, as an effective treatment method of turf as an alternative to disposal, it is conceivable to block the turf together with the soil and circulate it within the golf course so as to return to the soil.

  However, when such a soil and a biological material are mixed to form a block, in the former case, when the soil is pressed, the seed may be crushed and not germinate. In addition, when the soil is blocked by pressing, the particle size distribution becomes uneven, which may cause cracks in the block or break the block. Furthermore, the use of a considerable amount of curing agent for curing is not preferable as a culture medium, and has been a factor of high cost.

On the other hand, in the latter case, it is important to mix a large amount of turf in the block because the original purpose is to process a large amount of turf. Is not easy even with a strong press work, and a larger amount of curing agent is required. However, a block using a large amount of a curing agent does not easily return to the soil, and a turf circulation type treatment cannot be realized.

  Therefore, the problem of the present invention is that it can be mixed in a soil block without crushing biological materials such as seeds, and a larger amount of curing agent is used without causing cracks in the block or dividing the block. An object of the present invention is to provide a soil block mixed with a biological material, in which the biological material is mixed without being mixed, and a soil block manufacturing apparatus capable of manufacturing them.

The soil block of the present invention is a soil block formed by spreading a biological material and soil in a mold, and is disposed above the mold and is moved by a soil dispersion swinging tool that reciprocates like a mountain. , to disperse the soil, and by filling the mold in with rocking, that with soil blocks obtained by mixing biological material characterized in being densified in a state in which the particle size distribution is substantially uniform is there. The soil block manufacturing apparatus of the present invention is provided with a soil introduction port, a mold for densely filling the soil, and a lower side of the soil introduction port to drop the soil into the mold, and It has a soil dispersion rocker for dispersing and rocking the soil falling from the inlet, and a soil dispersion rocker operating mechanism for reciprocating the soil dispersion rocker. A soil block manufacturing apparatus characterized by

  Since the soil block of the present invention is not made into a block by press molding, it can be mixed in the soil block without crushing biological materials such as seeds. In addition, since the soil is formed by filling and forming the mold by dispersion and swinging, the impact acceleration between the soil and the mold is relaxed, and the particle size distribution is not biased, resulting in a substantially uniform soil block. It becomes a soil block that does not occur or break up. Furthermore, since it is densely packed by dispersion and rocking of the soil (in other words, it is packed so as to generate a self-organization phenomenon), even if biological materials such as seeds are mixed, a large amount It is densely blocked without the need for a curing agent.

  The soil block of the present invention is a soil block formed by spreading a biological material and soil in a mold, and the particle size is obtained by filling the mold while dispersing and shaking the soil. It is a soil block mixed with a biological material characterized by being densely distributed in a substantially uniform state, and can be manufactured using, for example, the manufacturing apparatus shown in FIGS.

Hereinafter, the soil block mixed with the biological material of the present invention will be described in detail together with the structure and operation of the manufacturing apparatus.

  The soil block of the present invention is produced by industrially utilizing the principle of forming a dense sand beach by relaxing friction between sand while waves roll up sand (dispersion and rocking).

  The soil block manufacturing apparatus 1 shown in the drawing is an apparatus that mechanically realizes such dispersion and swinging of the soil, in order to introduce the soil with a mold 2 for densely filling the falling soil. A hopper 3, a soil dispersion oscillating tool 4 for dispersing and oscillating soil block constituent materials such as soil falling from the hopper 3, and a soil dispersion oscillating tool vertically. And a soil dispersion rocker operating mechanism 5 for moving in the horizontal direction.

  As shown in FIG. 3, four mold frames 2 are connected to the base 6 (however, only two mold frames appear in FIG. 3). As the soil falls, the soil block 10 is formed by fine filling. Specifically, as shown in FIG. 1, the mold 2 is configured in a base 6, and a speed of 1.5 m / min in the left-right direction in FIG. 3 by a first driving means (motor) 7. It is configured to be able to reciprocate. Then, when the soil is filled in the mold 2 and moved to the left side in FIG. 3, the bottom plate 2a of the mold 2 is pushed up, and the soil block 10 of the present invention is lifted and removed as shown in FIG. Typed.

  The hopper 3 is an inlet for a soil block constituent material such as soil or biological material, and is attached to the upper part near the center of the soil block manufacturing apparatus 1 as shown in FIG. 1 or FIG. Open. The soil block constituent material may be input from the upper end opening of the hopper 3 or may be loaded on a conveyor mechanism (not shown).

  The soil dispersion rocking tool 4 is for dispersing and rocking soil block constituent materials such as soil falling from the hopper 3, and is fixed to the rocking body 12 as shown in FIGS. The upper flange 4a, the side walls 4b, the three erection parts 4c installed at the lower part of the both side walls 4b, and the two slits 4d provided between the erection parts 4c.

  The soil dispersion rocker operating mechanism 5 is a mechanism for moving the soil dispersion rocker 4 in the vertical and horizontal directions. As shown in FIG. 6, the second drive means (motor) 8 and the motor 8 A rotary shaft 8a, a disc 8b fixed to the rotary shaft 8a, an arm 9 having one end attached to the disc 8b via a crank pin, and the other end of the arm 9 attached to one end side are formed in a rectangular shape in plan view. The swinging main body 12 and the crank arm 11 which is arranged in four directions between the swinging main body 12 and the apparatus main body frame 13 and is rotatable about the pin on the apparatus main body frame 13 side.

  When the second drive means (motor) 8 is driven in such a soil dispersion rocker operating mechanism 5, as shown in FIG. 6 or FIG. 10, the arm 9 reciprocates every time the disk 8b rotates once. . As the arm 9 reciprocates, the oscillating body 12 also reciprocates. However, since the crank arm 11 rotates about the pin on the apparatus body frame side, the oscillating body 12 reciprocates with some vertical movement. exercise. Along with the operation of the swing body 12, the soil dispersion swing tool 4 fixed to the swing body 12 also moves in the vertical and horizontal directions. In the apparatus of this embodiment, the rotation speed of the motor is 50 rpm, and the movement distance in the vertical direction of the soil dispersion rocking tool 4 is set to 40 mm, and the movement distance in the horizontal direction is set to 160 mm.

  5 and 6 show a state in which the soil dispersion rocker 4 is positioned at the extreme end in the h direction (direction approaching the motor 8). The soil dispersion rocker 4 is as shown in FIG. In addition, it is located near one end side in the horizontal direction of the mold 2, and its lower end surface is located on the uppermost surface of the mold 2. 7 and 8 show a state in which the soil dispersion rocker 4 is located near the center of the mold 2 (see FIG. 7), and its lower end surface rises in the m direction and the mold 2 It is located 40 mm above the uppermost surface of. Further, FIG. 9 and FIG. 10 show a state in which the soil dispersion rocking tool 4 is located at the extreme end in the J direction (direction away from the motor 8). As shown, the mold 2 is located near the other end in the horizontal direction, and its lower end surface is located on the uppermost surface of the mold 2.

  That is, with the above structure, the soil dispersion rocking tool 4 performs rocking motion that repeats a reciprocating motion that draws a mountainous arc-shaped locus 50 times per minute. After passing through the slit 4d and the like, it is dropped as it is into the mold 2, and a part is placed on the upper surface of the erection part 4c (formed on a plane extending along the horizontal direction) to be horizontal or vertical. Further, when the soil that has fallen into the mold 2 exceeds the uppermost surface of the mold 2, it is dispersed on the lower surface of the erection part 4 c, and the particle size distribution of the soil block constituent material is substantially uniform. It works to be optimized (optimized), resulting in fine packing. In addition, the soil block of the present invention does not simply vibrate and distribute the soil or the like, and in particular, the construction part 4c formed in a flat plate shape extending in the horizontal direction moves in the vertical direction and the horizontal direction, Since the soil is placed on the upper surface and is dispersed and swayed so that the soil and the like are wound up, it is densified.

  In addition, the term “biological material” as used in the present application is a concept that includes a wide range of components that originally originated as living organisms in addition to living organisms themselves. Examples include grass and insect larvae.

  The soil block of the present invention contains a biological material and is densified with a substantially uniform particle size distribution. For example, germination can be achieved by mixing turf seeds in the soil block. A soil block can be formed, and lawn can be propagated only by laying the soil block in a garden or the like.

As a method for mixing seeds, a method in which the seeds are preliminarily placed in a mold is suitable.
In addition to soil, as constituent materials of the soil block, if necessary, cut grass, organic fertilizer, large sawdust, wood chips, charcoal, fungus, growth promoter or growth regulator, soil improver, spoilage promoter, A small amount of hardener such as cement may be used.

  As described above, the soil block mixed with the biological material of the present invention is not pressed and agglomerated, but has a uniform particle size distribution by dispersion and rocking. It can be mixed in the soil block without crushing, and the block is not cracked or divided, and it is agglomerated in a state of mixing biological materials without using a large amount of curing agent It can be used for various purposes depending on the type of biological material.
