[0027] To make the above-mentioned objectives, features and advantages of this utility model more apparent and understandable, the utility model will be further described in detail below with reference to the accompanying drawings and specific embodiments.
[0028] Example 1
[0029] like Figures 1-4As shown, this utility model provides a multifunctional silkworm rearing greenhouse, including a roof 1 and a greenhouse body 2. The roof 1, greenhouse body 2, and the ground on which the greenhouse body 2 is placed together form a silkworm rearing space, with silkworm seats at the bottom. The roof 1 has a double-layer insulation structure. The greenhouse body 2 has ventilation windows 3, and a shade net is installed on one side of the silkworm rearing space. An exhaust fan is also installed on the greenhouse body 2. A liftable upper cocooning frame 4 is suspended below the roof 1 and is located inside the silkworm rearing space. Square cocooning frames 5 are installed below the upper cocooning frame 4. A movable operator accommodation area 6 is provided above the silkworm seats.
[0030] The silkworm's growth process is divided into four stages: egg, larva (silkworm), pupa, and adult (silkworm moth). The larval stage is the main growth stage of the silkworm, divided into five instars. Each instar molts once, for a total of four molts, lasting approximately 20-30 days. At the end of the fifth instar, the silkworm spins its cocoon. Artificially raised silkworms are generally processed to obtain silk after the fifth instar silkworm spins its cocoon. The silkworm rearing area provides a place for the silkworm to eat leaves and move around, serving as the larval habitat. The square cocoon 5 is used for the fifth instar silkworms to attach to and spin their cocoons. Throughout the silkworm's growth process, a certain level of humidity and temperature needs to be maintained. Temperature can be regulated through ventilation, and humidity can be regulated through ventilation combined with humidification / dehumidification. In this invention, the ventilation window 3 is opened to ventilate and cool the silkworm rearing space when it is hot, and closed to gradually warm the space when it is cold. Shading nets prevent direct sunlight from reaching the silkworm rearing space. Ventilation fans maintain the necessary air exchange between the rearing space and the outside environment even when ventilation windows 3 are closed. However, the ventilation volume and area of the ventilation fans are smaller than those of ventilation windows 3. Air diffused into the rearing space through the ventilation fans flows slowly and does not affect the temperature rise of the rearing space. The roof 1 uses a double-layer insulation structure, effectively limiting indirect heat exchange between the rearing space and the outside environment, reducing the impact of outside temperature on the rearing space. A retractable cocooning frame 4 is suspended below the roof 1. Square cocooning frames 5 are placed on the frame 4. When the larvae enter the 5th instar, the frame 4, along with the square cocooning frames 5, descends to the silkworm rearing bed to facilitate larval climbing. Once all the larvae are on the frame, the frame 4, along with the square cocooning frames 5, rises together. This facilitates ventilation of the square cocooning frames 5, ensuring cocoon quality, and also allows silkworm rearing personnel to easily remove silkworm excrement from the rearing bed, preventing the spread of viruses and ensuring the safety of silkworm rearing (for already reared cocoons). Since the larvae primarily grow on the rearing bed, mulberry leaves need to be spread on it. The movable operator accommodation area 6 covers this rearing bed, allowing operators to complete the entire spreading process from within the operator accommodation area 6.
[0031] In one embodiment, the height of the grid cluster 5 is 1.5 meters.
[0032] In one embodiment, the double-layer insulation structure of the roof 1 has an interlayer, which is filled with thermal insulation material.
[0033] In one embodiment, the thickness of the interlayer is 5 cm, and the thermal insulation material is aerogel.
[0034] In one embodiment, the shed body 2 adopts a double-layer thermal insulation structure. There is an interlayer between the double-layer thermal insulation structures of the shed body 2, and the interlayer is filled with a thermal insulation material.
[0035] In one embodiment, the shed body 2 includes four enclosing walls. The adjacent enclosing walls are perpendicular to each other. The bottom shape of the shed body 2 is rectangular. The dimensions of the two opposite rectangular enclosing walls are the same. The shed roof 1 is in a "V" shape, and the shape of the top of the enclosing wall matches that of the shed roof 1.
[0036] In one embodiment, the ventilation windows 3 are arranged around the shed body 2. The area of the ventilation windows 3 is one-third of the area of the shed body 2. The distance from the bottom of the ventilation windows 3 to the bottom of the shed body 2 is equal to the distance from the top of the ventilation windows 3 to the top of the shed body 2.
[0037] In one embodiment, it further includes a temperature and humidity automatic detection device, which is arranged in the silkworm rearing space. The ventilation fan is a self-starting ventilation fan. An air conditioner is also arranged in the silkworm rearing space.
[0038] In one embodiment, a fixed hoisting frame is arranged below the shed roof 1. An electric winch is installed on the hoisting frame. A steel wire rope is wound around the electric winch, and the free end of the steel wire rope is connected to the mounting frame 4.
[0039] In one embodiment, a track 7 is arranged on the silkworm bed. The operator accommodation area 6 is arranged on the track 7. Below the operator accommodation area 6, there are wheels. The wheels are stably placed on the track 7 and can roll. The operator accommodation area 6 can be moved by directly driving the wheels with a motor. An independent traction device can also be arranged on the track 7, and the traction device is connected to the operator accommodation area 6 and drives the operator accommodation area 6 to move.
[0040] In one embodiment, support columns are arranged below the track 7. The support columns can lift the track 7 to avoid the track 7 occupying the silkworm bed space.
[0041] In one embodiment, a guardrail is arranged on the operator accommodation area 6.
[0042] In the description of the present application, it should be noted that unless otherwise clearly specified and limited, the terms "installation", "connection", and "connection" should be understood in a broad sense. For example, it can be a fixed connection, a detachable connection, or an integral connection; it can be a mechanical connection or an electrical connection; it can be a direct connection or an indirect connection through an intermediate medium, and it can be the connection of the interiors of two components. For those of ordinary skill in the art, the specific meanings of the above terms in the present application can be understood according to specific situations.
[0043] If this utility model discloses or relates to mutually fixedly connected parts or structural components, then, unless otherwise stated, a fixed connection can be understood as: a detachable fixed connection (e.g., using bolts or screws), or a non-detachable fixed connection (e.g., riveting, welding). Of course, mutually fixed connections can also be replaced by an integral structure (e.g., manufactured using a casting process) (except where it is obviously impossible to use an integral forming process).
[0044] In addition, unless otherwise stated, the terms used to indicate positional relationships or shapes in any of the technical solutions disclosed in this utility model above include states or shapes that are similar to, close to, or approximate with them.
