Description

  The present invention relates to a composting bag for fermenting and composting plant-based organic matter such as fallen leaves, lawn mowers and pruned branches, and agricultural and livestock waste such as rice husks and cut straw as raw manure.

  Conventionally, in order to collect and deposit plant-based organic matter and agricultural and livestock waste, and to compost after ripening and fermentation, an upper lid and a bottom lid that can be opened and closed on the top and bottom of a cylindrical body made of a breathable material are provided. A relatively large composting bag is used. And when taking out compost from this kind of bag, the bag was hung up by an appropriate means, and it was taken out so that a bottom lid might be opened.

  However, this type of composting bag, which is usually used outdoors, takes a long time for the internal raw fertilizer to ripen well. When the bottom of the composting bag was fully opened, the compost could not be taken out.

  Therefore, as disclosed in Patent Document 1, the applicant of the present application has proposed a composting bag that can be opened and closed in the vertical direction by a fastener or the like in at least one portion of the lower half of the body portion of the composting bag. . 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.

  However, in the case of a composting bag with such a structure, the internal pressure due to the sedimentation of the raw manure exerts a large force on the part that can be opened and closed by the fasteners in the lower half of the trunk, and the fasteners etc. may be torn right and left In addition, it was necessary to reinforce the part by tying a rope or the like separately, and on the structure where the trunk part was opened in the vertical direction, in order to avoid compost spilling from the side, it was folded inside the opening / closing part. It was structurally complicated, such as the need to provide a cloth for the shape.

  For this reason, as shown in Patent Document 2, the applicant of the present application has a cylindrical body portion made of a breathable material, an upper lid that can open and close the upper opening, and an extension of the body portion so as to be divided into a chrysanthemum shape. In a composting bag comprising a bottom receiving member and a discharge port portion that is sewn inside the barrel portion and closes the lower surface of the barrel portion, an elastic hoop is attached to the outer periphery of the portion of the trunk portion where chrysanthemum begins A composting bag is proposed. In the composting bag having such a structure, the hoop functions as a frame and the discharge port at the lower edge of the trunk portion is widely maintained in a circular shape, so that no compost bridge occurs in the portion. It will be discharged very easily.

  By the way, the composting bag as described above is easily composted by suspending the bag by an appropriate means and releasing the compost by opening the bottom part or the discharge port downward, even if the compost is a bridge. Although it can be taken out, the bottom of the bag is heavy, so it takes a lot of time to open the zipper on the bottom lid and unfasten the string that was tightened. Since a considerable amount of compost was sometimes released at once, it was a dangerous task.

  Then, an object of this invention is to provide the composting bag which enabled it to take out the completed compost easily and safely from the composting bag.

In order to solve the above problems, the present invention provides a cylindrical body (1) made of a breathable material, a bottom (10) for closing the bottom of the body (1), and the body (1). A composting bag comprising an upper lid (8) for closing the upper opening so as to be openable and closing, and having an upper suspension rope (11) attached to the upper end edge of the trunk (1), The reinforcing band cloth (5) is sewn at a predetermined interval in the vertical direction of the outer peripheral surface, and attachment rings (7) are sewn to the upper and lower ends of the reinforcing band cloth (5). Two lower suspension ropes (12) and (12) are crossed and attached to the ring (7), and a reversing rope (13) that can be hung by reversing the bag is attached to the central crossing part (12b). We adopted the means of

  Moreover, the means that the said upper cover consists of a water-permeable raw material was employ | adopted.

  The reversing rope employs a means in which a free end having a suspension ring formed at the tip has a length protruding from the outer peripheral edge of the bottom.

  Moreover, the means of sewing a wide band cloth on the outer periphery of the upper end edge and lower end edge of the trunk | drum was employ | adopted.

And the means of sewing a reinforcement band cloth further in the middle of the said upper and lower band cloth of the outer peripheral surface of a trunk | drum further at an appropriate space | interval was employ | adopted.

  The composting bag having the above-described configuration is provided with a reversing rope attached to the bottom of the trunk so that the bag can be reversed and suspended, so that compost can be easily discharged from the top opening, Thus, the dangerous work of opening the lid under the bag can be avoided.

  At this time, since the reversing rope is attached to the center crossing of the crossed lower suspension rope, the force when hanging the bag is concentrated at the center of the bottom of the bag, and the bag is routed through the lower suspension rope. Since the load is evenly applied to the peripheral edge, the bag can be safely and surely laid down and further inverted and suspended without deforming the bag. Further, a suspension ring is provided at the tip of the reversing rope, and this suspension ring is provided so as to protrude from the outer peripheral edge of the bag bottom, so that the suspension ring can be easily attached to a hook such as a crane. .

  On the other hand, since the wide band cloth is sewn on the outer periphery of the upper end edge and the lower end edge of the trunk portion, it can be maintained upright in a cylindrical shape when the bag is installed. The band at the lower edge also functions as a rain guard that prevents rain splashes from entering the bag.

  In addition, a reinforcing band cloth is sewn between the upper and lower band cloths at an appropriate interval, and a plurality of reinforcing band cloths are further sewn in the vertical direction on the outer periphery of the trunk part. It becomes easier to stand up, and the swelling of the trunk can be restricted to suppress the occurrence of bridges.

  Hereinafter, preferred embodiments of the composting bag according to the present invention will be described with reference to the drawings. FIG. 1 is a front view of a composting bag of the present invention, FIG. 2 (A) is a schematic bottom view of the composting bag, and FIG. In the figure, reference numeral 1 denotes a cylindrical body portion of a composting bag, which is made of a breathable material. Reference numeral 2 denotes a relatively wide band cloth sewn on the outer periphery in the vicinity of the lower edge of the body portion 1 and serves as a rain guard that prevents the splash of rain from entering the bag when it rains. Also, it functions as a rise of the bottom of the cylindrical body 1. Reference numeral 3 denotes a wide band cloth sewn on the outer periphery in the vicinity of the upper edge of the body portion 1 and functions to maintain the upper opening portion in a cylindrical shape. 4 and 4 are reinforcing band cloths of a predetermined width that are sewn on the outer periphery of the intermediate portion of the body 1 and function to maintain the body 1 of the bag in a cylindrical shape as described above. It also has a function of suppressing the occurrence of bridges by regulating the swelling of the part. Reference numerals 5 and 5 are reinforcing band cloths sewn in the vertical direction on the outer peripheral surface of the body 1 at regular intervals, and function to erect the body and keep it upright. Attachment rings 7, 7... For attaching a suspension rope described below are sewn to the upper and lower ends of the reinforcing band fabric 5 via the application cloths 6, 6. The attachment ring 7 is formed by folding a belt-like cloth in half.

  Reference numeral 8 denotes a disc-shaped upper lid that completely closes the upper surface opening of the body 1 and is provided so as to be freely opened and closed by a fastener 9 provided on the periphery. The material of the upper lid 8 is not particularly limited. For example, in order to prevent rain or the like from entering from the upper surface, a material made of a water-impermeable or hardly water-permeable material is used. Further, depending on the raw manure material to be stored, rain or the like may penetrate, and in that case, a water-permeable material may be used. Reference numeral 10 denotes a bottom portion that closes the bottom surface of the body portion 1, and is sewn to the periphery of the lower end of the body portion 1. The bottom portion 10 may be provided so as to be opened and closed with a fastener, like the upper lid 8. The bottom 10 is made of the same breathable material as that of the body 1.

  11 and 11 are upper suspension ropes attached to the upper end edge of the trunk portion 1 via the attachment ring 7... For hanging on a hook of a crane or an excavator when a bag is moved or transported. . As shown in FIG. 2 (B), the upper suspension rope 11 is attached to at least two places on the upper end edge of the trunk so that stable suspension is possible. Reference numerals 12 and 12 denote lower suspension ropes attached to the lower end edge of the body 1 via the attachment rings 7. As shown in FIG. 2 (A), the lower suspension ropes 12 and 12 are obtained by crossing two ropes twice so that three crossing portions 12a, 12b and 12c are formed at the central portion. It is attached. A reversing rope 13 having a free end protruding from the outer peripheral edge of the bottom 10 is attached to the central crossing portion 12b, and a hook such as a crane is attached to the free end. A suspension ring 14 is formed. The suspension rope 12 and the reversing rope 13 are for suspending the composting bag upside down as will be described later.

  The upper and lower suspension ropes only need to be able to suspend the composting bag with a crane or the like, and may be in the form of a belt or a belt, and the shape is not particularly limited. Also, the rope may be attached directly to the bag as long as it is a belt-like one in addition to the above-described attachment ring.

  Next, FIG. 3 presents a structure in which a locking tool 15 for the reversing rope 13 is provided on the side surface of the trunk portion 1 of the composting bag having the above configuration. As described above, the free end of the reversing rope 13 having the suspension ring 14 formed at the tip thereof protrudes from the outer peripheral edge of the bag bottom 10 so that a hook such as a crane can be easily attached. However, if it is as it is, it does not look good, and the presence of the reversing rope 13 may hinder the work. Therefore, a locking tool 15 that can lock the reversing rope is provided on the side surface of the body portion 1 and its tip is fixed so that the reversing rope 13 does not inadvertently obstruct work. Specifically, as shown in FIGS. (B) and (C), a separable strip 15b is sewn via a known buckle 15a, and the strip 15b is passed through the suspension ring 14 to pass through the buckle 15a. The reversing rope 13 can be fixed to the side surface of the trunk portion 1 by locking. In the above example, the buckle is illustrated as the locking means of the locking tool, but is not limited thereto, and known locking means such as a hook-and-loop fastener and a snap button can be adopted. The reversing rope may be fixed by connecting two strips.

  Then, the usage method of the composting bag of the said structure is demonstrated. First, a composting bag is installed in an appropriate place in the field and filled with plant-based organic matter such as fallen leaves, lawn mowers and pruned branches. In addition, depending on the degree of drying, water is added if necessary. Then, if left as it is, humus (aerobic fermentation) proceeds, and excellent compost can be obtained in a few months. On the way, additional fallen leaves etc. will be thrown in for the subsidence of natural weight.

  The completed compost is mixed with soil by horticultural farmers. In this case, since the hanging rope is provided on the upper surface of the bag, it can be easily transported using a crane or the like. In addition, when removing the compost from the bag, the bag is inverted and suspended to drop the contents. At this time, the lower suspension rope 12 and the reversing rope 13 are attached to the bottom surface of the bag, and the suspension ring 14 at the tip of the reversing rope 13 is provided so as to protrude from the bottom portion 10 of the bag. If a hook such as a crane is attached to the lower ring 14 and pulled up, the bag can be easily tumbled, inverted and suspended, and the compost falls due to its own weight. Further, in this case, since the generation of the bridge is suppressed by the reinforcing band cloths 4, 5, etc., the fall of the compost is not hindered.

  Since the reversing rope 13 is attached to the central crossing portion 12b of the lower suspension rope 12 on the bottom of the bag, when the reversing rope 13 is pulled up, the force is concentrated at the center of the bottom of the bag, Since the bag is evenly applied to the periphery, the bag can be laid down without being deformed, and it can be reversed and hung reliably.

It is a front view which shows an example of the composting bag which concerns on this invention. (A) is a bottom schematic diagram of a composting bag, and (B) is a top schematic diagram. The example which provided the locking tool in the trunk | drum side surface of the said composting bag is shown, (A) is a perspective view, (B) is an enlarged view of a locking tool part, (C) shows the example of a buckle. .
