Description

DETAILED DESCRIPTION OF THE INVENTION The present invention relates to a novel invention that enables mature silkworms to be efficiently wall-layered and kept in good condition during cocooning to obtain a high-quality surface.

Traditionally, various compartmentalized mawashi have been known, and among them, rotary mawashi is widely used. However, since mature silkworms are not evenly distributed in rotary mawashi, it is troublesome to correct it, and it is not necessary to hang it from the ceiling. It had a number of drawbacks, such as the fact that it had to be able to rotate freely, requiring a large amount of space.

The present invention improves such drawbacks and makes use of the wind-shielding property of silkworms.The silkworms are placed in an upright position, and the silkworms climbing from the bottom to the top are quickly blown from the top to the bottom. This allows the wall layer to be quickly and uniformly placed in each compartment.

A further object of the present invention is to provide an apparatus that can be suitably used in such a method.

This will be explained below with reference to the drawings.

Referring to Figures 1 and 2, 1 main body (1) is the upper frame (
Connect the lower frame (3) to 2), arrange them in parallel and fasten them with connecting rods (4) to form a frame, and if desired, connect the support rods (6) with turnbuckles (5) and (6) up and down. It is designed so that it can be disassembled and reassembled by being installed over the frame of the machine.

The upper frame and the lower frame.

As shown in Figure 3 and Figure ψ, the square pipe side rod (7)
, (7) is constructed by welding a horizontal rod (8) to the lower frame, and at the upper end of the lower frame there is a connecting rod (9) that is inserted into the lower end of the upper frame, and on both sides of the horizontal rod are as described below. A connecting rod OD for inserting and connecting a branch rod (10) is provided protrudingly. Furthermore, a pin for attaching a blower pipe, which will be described later, and a support pin Q3) for supporting a shelf element are protruded from appropriate parts of each horizontal rod. On the side of the side rod, there are pins (16
) Platinum 1 having a locking groove (17) for locking the
- (18) is fixed (see Figure 6), but it may not be provided.

As shown in the figure, the bracket has a substantially T-shaped opening in a U-shaped member and a slightly widened locking groove at the entrance H. The branch rod (10) has a support pin (21) at its end that supports the shelf element, and is assembled by passing through the connecting rod of the frame and connecting a bolt (not shown) to the insertion hole Cυ, (221). (Figure 2) (23+ is a protective cap.

The shelf element is composed of rods, plates, or other suitable supporting members so that one section of the mawashi can be placed in an upright position, and preferably has holes large enough to prevent mature silkworms from falling through. It is formed into a linear shape, a perforated plate shape, etc.

The one shown in the figure is composed of a net (24), and a side rod (25) (Fig. 7) is fixed with a nut (C) or the like between the upper ends of support pins protruding from the branch rod. Insert the bag-shaped part @ (Fig. r) formed at the end of the net body into the side rod (2
It passes through the top surface of the barrel and is stretched almost horizontally (dotted chain line in Fig. g). The mesh size of the mesh is approximately j on one side, j
It has been found that if the hole is formed into a rectangular hole with a diameter of approximately s mm, preferably about A mm, the silkworms will not stick out their heads, and the excrement such as feces and urine of the silkworms will fall downward without difficulty. The air pipe holder is
In the case of the one provided in the upper part of the shelf element and shown in Fig. 1, the insertion hole (30) is inserted into the pin α2 provided in the horizontal rod (Fig. 4).
Insert and secure. In addition, as shown in Figure R, it is best to position it slightly away from the center of the mawashi. As shown in FIG. 9, the ventilation holes Oυ provided in the ventilation pipe are provided so as to open approximately in the middle of the partitions placed on the shelf elements in an upright state, and are spaced at intervals of about 1,200 mm. Although it is provided on both sides of the lower part of the blower pipe, it can also be provided in any other suitable position. One end of the blower pipe is closed with a stopper (3a), and the other end is closed with a vertical pipe (3a) that communicates with the blower (Fig. It is inserted into the gloss.

Note that the blower pipe shown in FIG. 1 is made of a metal pipe, and the vertical pipe may be made of a plastic pipe. In the case shown in Figure 1, a blower is used as the air blowing means, and in the case shown in Figure 1 above the main body, the blower is preferably fixed to a suitable pedestal on the upper horizontal rod of the upper frame, and installed on the pedestal. , is connected to the upper part of the vertical pipe provided in an inverted U-shape and communicates with the ventilation pipe. By installing a blower at the top of the main body, even when the room temperature is low, the relatively warm air that has accumulated on the ceiling, etc., is circulated downward, making it possible to obtain an extremely good surface. Note that the blower may be provided below and its inlet hole may be opened above the main body. The main body can be fixedly installed, but it is better to install casters (3) as shown in the figure, and the urine receptacle (3
7) should be placed. In addition, in the case shown in Fig. 1, shelf elements are provided in μ stages on both sides of the main body so that partitions can be placed on both sides of the main body so that one box of silkworms can be stored at a time. The main bodies are arranged side by side and connected by connecting rods to form a total of 16 shelves, but the number of shelves can be increased or decreased as desired.

Then, an appropriate number (usually 70 pieces) of divided blinds 141 such as rotating blinds held by a support frame are placed between the shelf elements, and at this time, the shelf elements are made of a net as shown in Figure 1. Then, as shown in the figure, the net body is bent, and the distance between the lower surface of the mawashi and the net body becomes narrower, and silkworms do not cocoon in the gap on the lower surface.

Then, by using an appropriate silkworming tool, etc., and placing mature silkworms at the lower center of the mawashi, the silkworms will start to rise to the top of the mawashi according to their habit. At this time, during the mawashi period, air is blown from above to below, so the silkworms, hating the air currents, enter nearby plots and begin cocooning. Note that the amount of air blown is preferably set to a sufficient amount so that the silkworms show a reaction to the air flow due to their habits. Once all the silkworms are covered in this way, the silkworms can be cocooned while continuing to blow air, and the silkworms can be hung from the ceiling like a conventional rotating mapushi, or the silkworms that have fallen from the mawashi can be collected and cocooned again. This can save you the trouble of having to create a family.

As described above, according to the present invention, it is possible to process cocoons on the main body by feeding them into a divided mawashi such as a rotary mawashi, and the amount of urine urinated can be reduced to approximately μm by blowing air. l
The clearing rate of one surface has also improved significantly, with the remaining particles dispersing in the air.

High-quality cocoons can be obtained regardless of the weather.If a blower is installed above the main body, the high temperature in the upper part of the soil chamber can be blown to the lower part, making it easy to control the temperature of spring silkworms, late autumn silkworms, etc. When not in use, it can be placed on the shelf element to sterilize it, or used as an appropriate storage location.
