Description

[0001]
BACKGROUND OF THE INVENTION
The present invention relates to a composting bag for obtaining high-quality compost using agricultural and livestock waste such as rice husks and cut straw as raw manure. Further, the present invention relates to a new composting bag structure in which compost deposited and hardened in the composting bag to form a so-called bridge can be taken out easily and reliably.
[0002]
[Prior art]
Conventionally, composting bags have been widely adopted as means for efficiently composting agricultural and livestock waste such as rice husks and chopped straws. The general structure of the composting bag is, for example, provided with an upper lid and a bottom lid that can be opened and closed on the upper and lower sides of a cylindrical trunk sewn with a breathable material.
[0003]
This type of composting bag, which is usually used outdoors, takes a long time for the internal raw fertilizer to ripen well. It hardened and became a so-called bridge, and even when the bottom of the composting bag was fully opened, compost could not be taken out.
[0004]
Therefore, the applicant of the present application makes it possible to reduce a certain amount of the outer circumference of the lower half of the trunk of this type of composting bag, and when removing the compost, loosen the reduced part and widen the outlet. A composting bag is disclosed (Japanese Patent Laid-Open No. 9-278573). However, in order to take out the compost from the opening on the bottom, it is still necessary to crush the hardened compost to some extent, and the current situation is that it is taken out after poking with a stick from the bottom or hitting with a mallet It still took a lot of effort.
[0005]
[Problems to be solved by the invention]
For this reason, the applicant of the present application has further proposed a composting bag that can be opened and closed in the vertical direction by a fastener or the like in at least one part of the lower half of the body part of the composting bag (Japanese Patent Application No. 2000-033408). ). Thus, by making the longitudinal direction of the lower half of the trunk part openable / closable, the area of the take-out port from which compost can be taken out substantially increases, so that the compost that has hardened and becomes a bridge can be taken out as it is. Became.
[0006]
However, in the case of a composting bag having such a structure, a large force is applied to a portion that can be opened and closed by a fastener or the like in the lower half of the trunk due to the internal pressure due to the sedimentation of the raw manure, which may cause the fastener or the like to tear left and right. In addition, it was necessary to reinforce the part by tying a rope etc. separately, and on the inner periphery of the opening and closing part to avoid compost spilling from the side on the structure that opens the trunk part vertically It was structurally complicated, such as the need to provide a fold-like application cloth.
[0007]
Moreover, since this seed composting bag is used outdoors, it is necessary to have a means for preventing rain splashing at the lower end of the breathable trunk, and at least for stable installation, The lower end portion of the body portion preferably has a rising edge.
[0008]
The present invention is intended to solve the above-described problems, and discloses a composting bag that can be easily taken out so that the compost does not form a bottom swelling.
[0009]
[Means for Solving the Problems]
In the present invention, in order to solve the above-described problems, a cylindrical trunk portion made of a breathable material, an upper lid capable of opening and closing the upper opening, and a bottom receiving material that extends the trunk portion into a chrysanthemum shape. And a composting bag comprising a discharge port portion that is sewn inside the barrel portion and closes the lower surface of the barrel portion, and a means for attaching an elastic hoop to the outer periphery of the portion where the chrysanthemum splitting starts. It was decided to adopt. The material and specific configuration of the hoop will be described later.
[0010]
The composting bag of the above configuration is widely used in the state that the hoop functions as a frame and the discharge port on the lower edge of the trunk part is opened in a circular shape by attaching an annular hoop to the outer periphery of the part where the chrysanthemum part of the trunk part starts. Maintained. Therefore, the compost bridge does not occur in the portion, and the compost is discharged very easily.
[0011]
In addition, a belt cloth was sewn on the outer periphery of the portion where the chrysanthemum splitting of the trunk portion started, and the above-described annular hoop was attached to the belt cloth.
[0012]
Such a belt cloth prevents rain bounces from entering the bag, and also functions as a rise at the bottom of the cylindrical body so that the bag can be installed in a stable state. Become.
[0013]
Further, as a specific means for attaching the hoop, means for intermittently sewing a hoop thread in the circumferential direction along the outer periphery of the portion where the chrysanthemum part of the trunk portion starts, and inserting the hoop through the hoop thread. It was adopted.
[0014]
By inserting the hoop through the hoop, the hoop is integrated with the body portion, and therefore, the elasticity of the hoop and the frame function serve to keep the discharge port widely open in a circular shape.
[0015]
Further, as a more specific means of the hoop, a configuration was adopted in which a rod made of an elastic material was inserted into a bellows-like flexible hose, and a connecting portion was provided at both ends of the flexible hose to form a ring shape.
[0016]
In this configuration, the bar functions as a frame, while the flexible hose protects the bar and mitigates external impact.
[0017]
Further, as another means of the hoop, a configuration is adopted in which a rod made of an elastic material is covered with a hose made of foamed synthetic resin, and connecting portions are provided at both ends of the hose.
[0018]
Similarly to the flexible hose, the foamed synthetic resin also mitigates external impacts.
[0019]
Moreover, the hoop also employ | adopted the means of connecting the some pipe material which consists of a flexible tube mutually through a coupling member, and making it cyclic | annular.
[0020]
Even with such a hoop, the hoop functions as a frame and is widely maintained in a state in which the discharge port at the lower edge of the body portion is opened in a circular shape.
[0021]
In addition, as a more specific material for the bar material, a glass fiber rod that can be easily processed was adopted.
[0022]
DETAILED DESCRIPTION OF THE INVENTION
Hereinafter, a preferred embodiment of a composting bag according to the present invention will be described with reference to the drawings.
In FIG. 1, reference numeral 1 denotes a cylindrical body portion of a composting bag, which is made of a breathable material. Reference numeral 2 denotes an upper lid that closes the upper surface opening of the trunk portion, and is provided so as to be freely opened and closed by the fastener 3, and is made of a water-repellent material to prevent rain or the like from entering from the upper surface. preferable.

Is a bottom receiving material that extends the body part 1 and has a chrysanthemum shape, and seals the lower surface of the body part 1 after closing the lower surface of the body part 1 with a discharge port 8 described below. is there. Metal or synthetic resin rings 6, 6... Are attached to the front ends of the bottom receiving material 5, and ropes 7 are inserted into the rings 6, and the ropes 7 are drawn to seal the lower surface of the trunk. It can be stopped. Reference numeral 8 denotes a discharge port portion made of an inner bag sewn on the inside of the body portion 1 where the chrysanthemum starts, and 9 is a tape for binding and closing the discharge port portion 8. The bottom receiving member 5 and the discharge port 8 are both made of a breathable material. The above configuration is basically the same as that of a conventional composting bag.
[0024]
Next, 10 is a belt cloth sewn on the outer periphery of the lower edge of the body portion 1, that is, the part where the splitting of the bottom receiving material starts, and when raining, the splash of rain enters the bag. In addition to preventing rain, it also functions as a rise at the bottom of the cylindrical body. In addition, what is necessary is just to attach this belt cloth 10 as needed. Reference numeral 11 denotes an annular elastic hoop attached to the belt cloth 10 in order to maintain the opening of the lower edge of the body part. In order to attach this, a hoop for intermittently inserting the hoop 11 around the belt cloth 10. The throughs 12, 12... Are stitched. Then, the frame is formed by inserting the hoop 11 through the hoop thread 12, and the lower edge of the body portion is maintained in a circular shape. Therefore, the compost bridge is not formed in the portion, and the opening maintains a constant size, so that the compost can be easily discharged.
[0025]
FIG. 2 shows an example of a specific configuration of the hoop 11. Reference numeral 13 denotes an annular elastic member obtained by bending a glass fiber rod as an elastic member into a ring shape, and reference numeral 14 protects the periphery of the annular elastic member 13. The bellows-like flexible hose 15 (15a, 15b) is a pair of connecting portions for fitting the respective ends of the flexible hose 14 and maintaining them in a ring shape. This configuration is substantially simple and is completed by inserting the annular elastic member 13 into the flexible hose 14 having the connecting portions 15a and 15b at both ends. Then, it is sufficient to insert the hoop 11 into each hoop passage 12 at the lower edge of the body portion of the bag in a linear state where the connecting portion is not fitted, and finally, the connecting portions 15a and 15b are securely fitted.
[0026]
In addition, the structure of a connection part is not limited to embodiment shown in FIG. 2, What is necessary is just a structure which combines the both ends of a flexible hose reliably and does not remove | deviate easily.
[0027]
Moreover, although the said embodiment has disclosed what inserted the cyclic | annular elastic material 13 in the flexible hose 14 as a structure of a hoop, in this invention, the cyclic | annular elastic material 13 is not easily damaged by the impact from the outside. For example, instead of the flexible hose 14, a hose made of a foamed synthetic resin material such as urethane foam may be used as another embodiment. In this case, a connecting portion is necessary in order to connect both end portions into a ring shape.
[0028]
Further, in addition to the above embodiments, the flexible hose 14 for protecting the annular elastic material 13 or the hose made of the foamed synthetic resin material is omitted, and the frame is formed by directly inserting the annular elastic material 13 into the hoop passage 12. May be configured.
[0029]
Moreover, in each said embodiment, the cyclic | annular elastic material 13 is not limited to what bent the single glass fiber rod in the ring shape. That is, for example, as shown in FIG. 3, a plurality of glass fiber tubes 16, 16,... Are bent into a ring shape and connected to each other via a connecting member 17 such as a fume tube having a taper. A hoop may be constructed. In this case, it is preferable that a single rubber string 18 is inserted into each glass fiber tube 16 so that each tube does not fall apart. Then, the hoop having such a configuration is inserted through the hoop to form a frame. Also by such a hoop, the lower edge of the trunk is maintained in a circular open state.
[0030]
【The invention's effect】
As described above, in the composting bag according to the present invention, the hoop is attached to the outer periphery of the lower edge of the trunk portion, so that the raw manure may ripen and accumulate in the bag and harden. However, a frame is constructed at the discharge opening at the lower end of the bag, and this part is widely maintained at a constant size, so that the bridge is not caught when the compost is discharged, and the compost can be discharged very easily. Play.
[0031]
In addition, by providing a belt cloth on the outer periphery of the lower edge of the trunk, it prevents rain and prevents the compost from getting wet more than necessary, and forms a rise at the bottom of the bag, which stabilizes the bag. And can be installed.
