BACKGROUND OF THE INVENTION 1. Field of the Invention The present invention relates to a composting bag for composting agricultural and livestock wastes such as branches and leaves, weeds, and the like, which promotes composting of raw manure by leaving it outdoors. .

[0002]

2. Description of the Related Art Conventionally, branches and leaves, weeds, and the like, which are industrial wastes of agriculture and animal husbandry, have been used as fertilizers by utilizing the natural decomposition power. The composting bags used to make such fertilizers generally include a tubular bag body,
It consists of an upper lid that can be opened and closed with respect to the bag body, and all of its material is made of breathable mesh or the like. This is because composting of agricultural and livestock waste, which is raw manure,
Because it is due to the decomposition of microorganisms that exist in nature,
This is because it is necessary to maintain air permeability inside the bag to promote fermentation.

FIG. 6 shows an example of the above-mentioned composting bag, wherein 1 is a bag body, 2 is a top cover of the bag, and 3 is a fastener which can open and close the top cover. . After the raw manure is put in, it is left outdoors for about one to several months to ripen, and the compost is taken out and used.

[0004] In order to ripen the raw manure properly, in addition to the above-mentioned air permeability, an appropriate amount of moisture is required. In a dry state, the problem is solved by spraying water over the composting bag. However, in a rainy season such as the rainy season, excessive moisture does not promote ripening well, which is inconvenient. In order to solve such a problem, during heavy rain, the composting bag itself is moved under eaves or the like, or a water-resistant sheet is put on the composting bag. However, it is difficult to move the composting bag after feeding the raw manure due to its excessive weight, and it is difficult to cover the water-resistant sheet in the rain.

An object of the present invention is to solve the above-mentioned problem, and discloses a composting bag which keeps air permeability and prevents excessive raindrops from being applied in rainy weather.

[0006]

According to the present invention, in order to solve the above-mentioned problems, in a composting bag, a tubular bag body made of a breathable material and a bag body which can be opened and closed are provided. An upper lid made of a breathable material and a water-resistant sheet covering the upper lid were formed, and the water-resistant sheet was joined only on a line passing through the center of the upper lid. By adopting such a means, the water-resistant sheet can be easily rolled up. In fine weather, the water-resistant sheet is rolled up to maintain air permeability from above, and in rainy weather, the water-resistant sheet is placed on the top cover. Can be spread out to avoid rain.

Further, in the compost bag, the water-resistant sheet is made larger than the top lid, and the protruding portion is used as an eave so as to sufficiently cope with an area having a large amount of rainfall.

DETAILED DESCRIPTION OF THE PREFERRED EMBODIMENTS Preferred embodiments of the present invention will be described below with reference to the accompanying drawings. FIG.
1 shows a first embodiment of the present invention, wherein 1 is a cylindrical bag body made of a breathable material, 2 is an upper lid made of a breathable material provided to be openable and closable with respect to the bag body, 3 is A fastener for opening and closing the bag body and the upper lid, 4 is a water-resistant sheet covering the upper lid, 5 is an upper lid, and shows a joint portion of the water-resistant sheet joined only on a line passing through the center thereof. ing. A characteristic configuration of the present embodiment is that the water-resistant sheet is joined on a line passing through the center of the upper lid. That is, the water-resistant sheet is spread so as to cover the upper lid in rainy weather, so that raindrops do not fall on the upper lid, and in fine weather, the water-resistant sheet is rolled up along the joining line to keep the ventilation hole from the upper lid. It is. In the present embodiment, since the water-resistant sheet is joined only on a line passing through the center of the upper lid, it is easy to spread and turn the sheet, and also in the case of a strong wind, the sheet is skipped. It also has the advantage of not being lost.

FIG. 2 is a front view of FIG. 1, in which (a) shows a mode in rainy weather and (b) shows a mode in fine weather. As shown in (a), when it is raining, the water-resistant sheet 4 is used so as to cover the upper lid. Therefore, the raindrops are repelled by the water-resistant sheet 4 and cannot enter the bag through the upper lid. And the water content in the bag is kept constant without becoming excessive.
On the other hand, as shown in (b), when the weather is fine, by turning the water-resistant sheet 4 toward the joint portion of the upper lid, sufficient external air can be taken in from the ventilation holes of the upper lid. Of course, when the amount of water in the bag is insufficient, it is also possible to turn the water-resistant sheet and expose the upper lid to allow a necessary amount of rain to enter inside even in rainy weather. Conversely, in the case of sunshine, it is possible to prevent the moisture in the bag from evaporating and the compost from drying by covering with a water-resistant sheet.

By the way, the method of rolling up the water-resistant sheet in the present invention is such that the surface of the upper lid is exposed by, for example, winding or folding the water-resistant sheet toward the joint, so that the ventilation hole is secured. It broadly includes methods for compacting sheets. Of course, as shown in FIG. 1, the air hole of the upper lid can be secured by folding half of the water-resistant sheet to the opposite side, and thus the present invention is intended. FIG. 3 is an example showing a method for keeping a water-resistant sheet made of a material that immediately spreads out even when the water-resistant sheet is rolled up. It is tied with string 6.
The cord 6 is provided between the upper lid and the water-resistant sheet 4 so as to be orthogonal to the joining portion of the sheet. After the water-resistant sheet 4 is wound toward the joining portion of the sheet, the cord 6 is orthogonal to the winding direction. This state is maintained by tying the string 6 to be connected.
Also, the joining method of the upper lid and the water-resistant sheet includes sewing,
The method is not particularly limited as long as the upper lid and the water-resistant sheet can be joined in one line by welding or the like. In all the embodiments shown in the present application, there is no difference in the fundamental configuration, and therefore, the same components are denoted by the same reference numerals.

On the other hand, FIG. 4 shows a different embodiment of the present invention.
have. In this embodiment, the water-resistant sheet 4 is provided slightly larger than the upper lid, and the protruding portion is used as an eave. By providing eaves, it can be used when rainfall is high,
It is possible to cope with the case where there is a lot of rain from the oblique direction. FIG. 5 is an embodiment corresponding to a case where the water-resistant sheet is easily rolled up by wind or the like in a state where the water-resistant sheet is spread. 8 are provided. When it rains,
By fastening the water-resistant sheet and the hook 8 provided on the bag body, it is possible to prevent the water-resistant sheet from being easily turned up even in heavy rain.

The water-resistant sheet is not particularly limited as long as it has water resistance and can be folded or wound. Specifically, tarpaulin paper, polyethylene film, vinyl sheet and the like can be adopted.

In any of the above embodiments, an outlet may be provided so that compost can be taken out from below the bag body. The configuration of the outlet is not particularly limited, but it may be configured to be openable and closable by a fastener or the like as in the case of the upper lid, or a widely-known technique such as providing a chrysanthemum-shaped bottom receiving material may be widely used. it can.

[0014]

According to the present invention, by providing a water-resistant sheet on the upper surface of the top lid of the composting bag, it is possible to prevent excessive moisture from penetrating into the bag during heavy rain. It became.

Further, since the water-resistant sheet is joined only on a line passing through the center of the upper lid, the water-resistant sheet can be freely turned along the joining line. Therefore, in fine weather, etc., the sheet is turned up and the air hole of the upper lid comes into contact with the outside air, so that the air permeability in the bag can be sufficiently ensured.
