Description

Technical Field

[0001] This utility model belongs to the field of edible fungi production technology, specifically relating to a self-heating, oxygen-enriched, temperature-controlled double-layer mycelium growth shed. Background Technology

[0002] In edible mushroom cultivation, the temperature and oxygen content inside the mycelium incubation shed are crucial. During the mycelium incubation stage, the mycelium needs a suitable temperature and oxygen level to grow and develop. Typically, these parameters must be maintained within a certain range to ensure normal mycelial metabolism and reproduction. Especially in northern regions with large diurnal temperature variations, particularly in cold winters, a combustion furnace or electric heating system is commonly used to maintain a stable temperature environment inside the incubation shed. However, these heating methods are costly to install and consume significant amounts of materials and electricity, greatly increasing the cultivation cost. Furthermore, the combustion of materials depletes oxygen within the shed, leading to mycelial hypoxia during the incubation period and hindering healthy mycelial growth. Utility Model Content

[0003] This utility model provides a self-heating, oxygen-enriched, temperature-controlled double-layer mycelium incubation shed, which aims to solve the problems of high heating costs and insufficient oxygen supply affecting mycelial growth in the existing technology during the cultivation of edible fungi.

[0004] To achieve the above objectives, the technical solution adopted by this utility model is: to provide a self-heating, oxygen-enriched, temperature-controlled double-layer mycelium incubation shed, comprising:

[0005] Inner canopy;

[0006] An outer canopy is installed on the outside of the inner canopy, and the outer canopy and the inner canopy form an insulated space. A ventilation mechanism is also provided on the bottom side of the outer canopy to control the connection between the insulated space and the outside.

[0007] An air supply duct includes an air inlet section and an air outlet section. The air inlet section is located inside the insulation space and is arranged along the length of the outer canopy. Multiple air inlets are provided on the side wall of the air inlet section, and the multiple air inlets are arranged at intervals along the length of the air inlet section. The air outlet section is located inside the inner canopy and is arranged along the length of the inner canopy. Multiple air outlets are provided on the side wall of the air outlet section, and the multiple air outlets are arranged at intervals along the length of the air outlet section.

[0008] A fan, installed on the air duct, is used to transport air from the inlet section to the outlet section.

[0009] In one possible implementation, the air inlet section is located at the top of the inner canopy and at the middle of the inner canopy along its width.

[0010] In one possible implementation, the air intake volume located in the middle of the air intake section is greater than the air intake volume at both ends of the air intake section.

[0011] In one possible implementation, the density of the air inlet in the middle of the air inlet section is greater than the density of the air inlets at both ends of the air inlet section.

[0012] In one possible implementation, the inner shed is further equipped with a ventilation duct for communicating with the outside, and the ventilation duct is equipped with a one-way valve to prevent outside air from entering the inner shed.

[0013] In one possible implementation, the ventilation duct extends through the insulation space, and an upwardly bent elbow is fixedly installed at one end of the ventilation duct located on the outer side of the outer canopy.

[0014] In one possible implementation, the air inlet of the ventilation duct is located near the floor of the inner canopy.

[0015] In one possible implementation, the ventilation mechanism is a film roller disposed on the side of the outer canopy for controlling the communication state between the outer canopy and the outside.

[0016] In one possible implementation, the film roller is provided on one or both sides along the width direction of the outer canopy.

[0017] In one possible implementation, the inner canopy includes two spaced-apart covering layers and an insulation layer located between the two covering layers.

[0018] The solution shown in this application, compared with the prior art, involves an inner shed covered by an outer shed. The top, two ends, and both sides of the inner shed are spaced apart from the outer shed, thus forming an insulated space between the inner and outer sheds. An air duct is installed between the inner and outer sheds. The two ends of the air duct are closed structures, with the air inlet section located inside the insulated space and the air outlet section located inside the inner shed. A fan is installed in the middle of the air duct. The fan is installed at the connection between the air inlet and air outlet sections, with the fan inlet connected to the air inlet section and the fan outlet connected to the air outlet section. In this application, during the day, the temperature inside the insulated space rises due to sunlight. When the temperature inside the inner shed reaches the minimum standard value, the fan starts and delivers air from the insulated space to the inner shed. This design increases the temperature inside the inner greenhouse, and the air outlet section of the air duct is arranged along the length of the inner greenhouse, ensuring that the air delivered to the inner greenhouse is evenly distributed, thus guaranteeing a uniform temperature distribution inside the inner greenhouse. This application allows for the delivery of warmer air from the insulated space to the inner greenhouse to raise and stabilize the internal temperature. It also features low power consumption during operation, reducing heating costs in the mushroom shed during cold seasons. Furthermore, the ventilation mechanism on the outer greenhouse controls the connection between the insulated space and the outside environment, allowing outside air to circulate into the insulated space when the fan is running. After being heated, the air is delivered to the inner greenhouse through the air duct, ensuring sufficient oxygen levels and providing a stable environment for mycelial growth.

[0024] To make the technical problems, technical solutions, and beneficial effects of this utility model clearer, the present utility model will be further described in detail below with reference to the accompanying drawings and embodiments. It should be understood that the specific embodiments described herein are merely illustrative of the present utility model and are not intended to limit the present utility model.

[0025] Please refer to the following: Figure 1 and Figure 2 The present invention describes a self-heating, oxygen-enriched, temperature-controlled double-layer mycelium incubation shed. The self-heating, oxygen-enriched, temperature-controlled double-layer mycelium incubation shed includes an inner shed 1, an outer shed 2, a conveying pipe, and a fan 4. The outer shed 2 covers the outside of the inner shed 1, forming an insulated space between them. A ventilation mechanism for controlling the connection between the insulated space and the outside is also provided on one side of the bottom of the outer shed 2. The air conveying pipe 3 includes an inlet section 31 and an outlet section 32. The inlet section 31 is located inside the insulated space and is arranged along the length of the outer shed 2. Multiple air inlets are provided on the side wall of the inlet section 31, spaced apart along its length. The outlet section 32 is located inside the inner shed 1 and is arranged along its length. Multiple air outlets are provided on the side wall of the outlet section 32, spaced apart along its length. The fan 4 is installed on the air conveying pipe 3 and is used to convey air from the inlet section 31 to the outlet section 32.

[0026] The self-heating, oxygen-enriched, temperature-controlled double-layer mycelium growth shed provided in this embodiment, compared with the prior art, features an inner shed 1 covered by an outer shed 2. The top, two ends, and sides of the inner shed 1 are spaced apart from the outer shed 2, thus forming an insulated space between the inner shed 1 and the outer shed 2. An air duct 3 is installed between the inner shed 1 and the outer shed 2. The two ends of the air duct 3 are closed structures, with the air inlet section 31 located inside the insulated space and the air outlet section 32 located inside the inner shed 1. A fan 4 is also installed in the middle of the air duct 3. The fan 4 is installed at the connection between the air inlet section 31 and the air outlet section 32, with the air inlet of the fan 4 connected to the air inlet section 31 and the air outlet of the fan 4 connected to the air outlet section 32. In this application, during the day, the temperature inside the insulated space rises due to sunlight. When the temperature inside the inner shed 1 reaches its lowest standard value, the fan 4 starts and delivers air from the insulated space to the inner shed 1 to raise the temperature inside the inner shed 1. Furthermore, the air outlet section 32 of the air duct 3 is arranged along the length of the inner shed 1, ensuring that the delivered air is evenly distributed within the inner shed 1, thus guaranteeing a uniform temperature distribution. This application can deliver warmer air from the insulated space to the inner shed 1 to raise and stabilize its temperature. It also features low power consumption during operation, reducing heating costs in the mushroom shed during cold seasons. Simultaneously, the ventilation mechanism on the outer shed 2 controls the connection between the insulated space and the outside environment, allowing outside air to circulate into the insulated space when the fan 4 is operating. After being heated, outside air is delivered to the inner shed 1 through the air duct, ensuring sufficient oxygen levels within the inner shed 1 to maintain a stable environment for mycelial growth.

[0027] Specifically, in this embodiment, the fan 4 is a variable frequency fan, and the fan 4 is electrically connected to a controller. The controller is electrically connected to a sensor for detecting the internal temperature of the inner shed 1. The air volume of the air outlet section on the air duct 3 can be adjusted by controlling the speed of the fan 4, thereby adjusting the internal temperature of the inner shed 1 and achieving the effect of automatic temperature control.

[0028] In some embodiments, the air inlet section 31 described above can be adopted as follows: Figure 1 The structure is shown in Figure 2. See also... Figure 1 , Figure 2The air inlet section 31 is located at the top of the inner canopy 1 and in the middle of the width direction of the inner canopy 1. The top of the inner canopy 1 and the outer canopy 2 have an arc-shaped cross-section perpendicular to the length direction of the inner canopy 1 or the outer canopy 2, and the middle of the arc-shaped structure is the highest point. The air inlet section 31 is located at the top of the inner canopy 1 and at the highest point of the arc-shaped structure. During normal use, the air inside the insulation space will rise as the temperature rises, so that the highest point of the insulation space has the highest temperature. When the air is delivered to the interior of the inner canopy 1, the higher temperature air can be drawn into the air inlet section 31, improving the efficiency of heating the interior of the inner canopy 1.

[0029] In some embodiments, the air inlet section 31 described above can be adopted as follows: Figure 1 The structure is shown in Figure 2. See also... Figure 1 , Figure 2 The air intake volume in the middle of the air intake section 31 is greater than that at both ends of the air intake section 31. When the fan 4 draws air from inside the air intake section 31 into the air outlet section 32, the air intake volume in the middle of the air intake section 31 is greater than that at both ends of the air intake section 31. Since the two ends of the air intake section 31 are located at the two ends of the inner shed 1 and the outer shed 2, the temperature at the two ends of the inner shed 1 and the outer shed 2 along the length direction is lower than that in the middle due to the influence of the outside temperature. When the air intake section 31 draws in air, it can draw in a large amount of the warmer air in the middle, while the air transport volume in other parts is less than that in the middle, ensuring that the high-temperature gas inside the insulation space can be preferentially transported to the inner shed 1 through the air duct 3.

[0030] In some embodiments, the air inlet section 31 described above can be adopted as follows: Figure 1 The structure is shown in Figure 2. See also... Figure 1 , Figure 2 The density of air inlets in the middle of the air inlet section 31 is greater than that at both ends of the air inlet section 31. The length direction of the air inlet section 31 is arranged along the length direction of the inner canopy 1. Multiple air inlets are arranged on the air inlet section 31, and the air inlets are arranged sequentially at intervals along the length direction of the air inlet section 31. The distance between two adjacent air inlets gradually decreases towards the middle of the air inlet section 31, so that the number of air inlets in the middle of the air inlet section 31 is greater than the number of air inlets at both ends of the air inlet section 31. When the fan 4 draws air from inside the air inlet section 31, the air intake volume located in the middle of the air inlet section 31 is greater than the air intake volume at both ends of the air inlet section 31.

[0031] Preferably, in this embodiment, the air inlet on the air inlet section 31 is located at the top of the air inlet section 31, which can preferentially draw in the high-temperature air above the air inlet section 31.

[0032] In some embodiments, the inner canopy 1 described above can be adopted as follows: Figure 1 The structure is shown in Figure 2. See also... Figure 1 , Figure 2 The inner shed 1 is also equipped with ventilation pipes 5 for communication with the outside. One-way valves 51 are installed on the ventilation pipes 5 to prevent outside air from entering the inner shed 1. Multiple ventilation pipes 5 are installed inside the inner shed 1, spaced apart along its length. One-way valves 51 are installed on each ventilation pipe 5. When the fan 4 is started, air is delivered from the insulated space to the inner shed 1, while the air inside the inner shed 1 can be discharged to the outside through the ventilation pipes 5, thus ensuring a stable pressure differential inside the inner shed 1. The one-way valves 51 on the ventilation pipes 5 ensure that air inside the inner shed 1 can only be delivered to the outside, while cold outside air cannot circulate into the inner shed 1, preventing it from affecting the temperature inside the inner shed 1.

[0033] Specifically, in this embodiment, the ventilation pipe 5 is located on one or both sides of the inner canopy 1, and is located at the bottom of the inner canopy 1.

[0034] In some embodiments, the ventilation duct 5 may be as follows: Figure 1 The structure is shown in Figure 2. See also... Figure 1 , Figure 2 The ventilation duct 5 runs through the insulated space, and an upward-bent elbow 52 is fixedly installed at the end of the ventilation duct 5 located on the outer side of the outer canopy 2. The air outlet of the ventilation duct 5 is located inside the inner canopy 1, and the air inlet of the ventilation duct 5 is located on the outer side of the outer canopy 2. The upward-bent elbow 52 at the outer side of the ventilation duct 5 prevents the air outlet 5 from being buried by snow in winter, thus affecting the normal use of the ventilation duct 5.

[0035] Specifically, in this embodiment, a cover plate is also installed above the air outlet of the ventilation pipe 5. The cover plate is arranged vertically at intervals from the air outlet and is located above the air outlet to prevent snowflakes from falling into the air outlet.

[0036] In some embodiments, the ventilation duct 5 may be as follows: Figure 1 The structure is shown in Figure 2. See also... Figure 1 , Figure 2 The air inlet of ventilation duct 5 is located near the ground of the inner shed 1. Ventilation duct 5 is installed above the ground inside the inner shed 1, allowing air to be exhausted from the ground side of the inner shed 1. The air outlet section 32 of air supply duct 3 is located at the top of the inner shed 1, with warmer air located at the top and cooler air at the bottom, allowing the cooler air to be exhausted from the ventilation duct 5. Warmer air is supplied to the inner shed 1 through the air inlet section 31 of air supply duct 3, ensuring air circulation and maintaining adequate oxygen levels inside the inner shed 1. This system guarantees both the temperature and oxygen levels inside the inner shed 1, providing a favorable environment for the growth of the microorganisms.

[0037] In some embodiments, the outer canopy 2 may be adopted as follows: Figure 1 The structure is shown in Figure 2. See also... Figure 1 , Figure 2 The ventilation mechanism is a film roller 6 installed on the side of the outer canopy 2 to control the connection between the outer canopy 2 and the outside. The film roller 6 can roll up the plastic film close to the ground on the side of the outer canopy 2, connecting the side of the outer canopy 2 to the outside. When the fan 4 is working, the film roller 6 can roll up the plastic film on the side of the outer canopy 2, maintaining the pressure difference between the outer canopy 2 and the outside. Simultaneously, it can draw outside air into the insulated space, ensuring the oxygen content inside the air. The film roller 6 also rolls up the plastic film at the bottom of the side of the outer canopy 2, allowing outside air to enter the insulated space from the bottom and be transported to the delivery pipe, ensuring orderly airflow from bottom to top within the insulated space. This prevents cold air from being directly drawn into the air duct 3, which could affect the temperature inside the inner canopy 1.

[0038] In some embodiments, the outer canopy 2 may be adopted as follows: Figure 1 The structure is shown in Figure 2. See also... Figure 1 , Figure 2 A film roller 6 is provided on one or both sides along the width direction of the outer canopy 2. In this embodiment, a film roller 6 is provided on one side of the outer canopy 2, allowing air to enter the interior of the insulation space from that side. Furthermore, the side with the film roller 6 is the sun-facing side, thus allowing air from the side with the higher temperature inside the insulation space to be transported to the air inlet section 31 of the air duct 3.

[0039] Optionally, in this embodiment, film rollers 6 are simultaneously provided on both sides of the outer canopy 2, allowing air to enter the insulation space from both sides of the outer canopy 2. This ensures effective air circulation within the insulation space and guarantees the oxygen content of the air delivered to the inner canopy 1.

[0040] Specifically, in this embodiment, the specific structure and installation method of the film winding machine 6 adopt existing technology, and will not be described further here.

[0041] In some embodiments, the inner canopy 1 described above can be adopted as follows: Figure 3 The structure shown. See also Figure 3The inner shed includes two spaced-apart covering layers 12 and an insulation layer 11 located between the two covering layers 12. Both the outer and inner layers of the inner shed 1 are located within the covering layers 12, which are made of plastic sheeting. An insulation layer 11, made of beaded wool, rock wool, or glass wool, is also installed between the two covering layers 12. This effectively improves the insulation effect of the inner shed 1. Furthermore, the air inside the insulation space flows in from the outside through the film roll-up device 6 on the side of the outer shed 2, and heats up during the flow before being transferred to the interior of the inner shed 1, thus ensuring the internal temperature and oxygen content of the inner shed 1.

[0042] The above description is only a preferred embodiment of the present utility model and is not intended to limit the present utility model. Any modifications, equivalent substitutions and improvements made within the spirit and principles of the present utility model should be included within the protection scope of the present utility model.
