Description

Technical Field

[0001] The utility model relates to the technical field of Agaricus bisporus planting houses, and particularly relates to a ventilation device for an Agaricus bisporus planting house. Background Art

[0002] Agaricus bisporus is a fungus of the genus Agaricus in the family Agaricaceae, also known as white mushroom, mushroom, portobello mushroom, etc. It is a globally cultivated and consumed mushroom and is widely distributed throughout the northern temperate zone.

[0003] When an Agaricus bisporus planting house is used to plant Agaricus bisporus, its ventilation requirements are crucial for the growth of the mushrooms. It directly affects the growth rate of the mycelium, the formation of the fruiting body, as well as the yield and quality.

[0004] The utility model patent with the Chinese patent publication number CN214102592U has the title of a ventilation device for an Agaricus bisporus planting house, which includes a frame body. A fan housing is fixedly sleeved inside the frame body. Ventilation holes are opened on the front and rear sides of the fan housing. An exhaust fan is fixedly installed inside the fan housing. Fixed columns are respectively fixedly connected to the left and right sides of the inner wall of the frame body. An activity sleeve is movably sleeved on the outside of the fixed column. A closed window leaf is fixedly connected to the inside of the activity sleeve. A rotating belt is movably sleeved on the outside of the activity sleeve. A rotating shaft is movably sleeved at the bottom of the inner cavity of the rotating belt. A rotating knob is fixedly installed on the right side of the rotating shaft. In summary, when using this ventilation device for an Agaricus bisporus planting house, by installing the device at the window, during use, by rotating the rotating knob 10, the rotating knob 10 drives the rotating shaft 9 to rotate. At the same time, the rotating shaft 9 drives the rotating belt 8 to rotate. The rotation of the rotating belt 8 drives the rotation of the activity sleeve 6. The rotation of the activity sleeve 6 rotates around the fixed column 5. At the same time, the activity sleeve 6 drives the closed window leaf 7 to rotate. The closed window leaf 7 is opened to conduct air exchange between the indoor and outdoor, so that the indoor temperature and humidity are maintained at an appropriate level. When the air circulation is slow, the exhaust fan 4 can be turned on to accelerate the air exchange between the indoor and outdoor. When the outdoor environmental temperature is low, by rotating the rotating knob 10, the rotating knob 10 drives the rotating shaft 9, the rotating belt 8 and the activity sleeve 6 to rotate, so that the activity sleeve 6 drives the closed window leaf 7 to rotate and closes the closed window leaf 7 to prevent cold air from entering the room. That's it. This solution installs the device in the window, and then achieves the air exchange operation in the Agaricus bisporus planting house by adjusting the opening angle of the closed window leaf and the start and stop of the exhaust fan in the device. However, when planting Agaricus bisporus, specific ventilation requirements need to be considered, including aspects such as ventilation volume, ventilation time, ventilation method, and ventilation precautions. Reasonable ventilation management can provide good environmental conditions for the growth of Agaricus bisporus. The ventilation method in the above solution is relatively simple and may lead to a reduction in yield. Therefore, a ventilation device for an Agaricus bisporus planting house is now proposed. Content of the Utility Model

[0005] (1) Technical problem to be solved

[0006] In view of the deficiencies of the prior art, the utility model provides a ventilation device for a double-spore mushroom planting house, which solves the problems raised in the above-mentioned background art.

[0007] (2) Technical solution

[0008] To achieve the above object, the utility model is realized through the following technical solutions: A ventilation device for a double-spore mushroom planting house includes a double-spore mushroom planting house, and at least one first ventilation window structure capable of communicating with the inside of the double-spore mushroom planting house is provided in the double-spore mushroom planting house. At least one second ventilation window structure capable of communicating with the inside of the double-spore mushroom planting house is provided in the double-spore mushroom planting house. The first ventilation window structure and the second ventilation window structure are arranged corresponding to each other. A draft tube communicating with the inside of the double-spore mushroom planting house is provided in the double-spore mushroom planting house. By providing the first ventilation window structure and the second ventilation window structure, they can be arranged according to the second ventilation method described below, so that the two ventilation window structures are arranged at the north and south ends of the mushroom house, which is conducive to forming a convective wind and improving the ventilation effect. Moreover, the settings of the first ventilation window structure and the second ventilation window structure need to open and close the two ventilation window structures according to the production process of double-spore mushrooms and can control the ventilation volume. By providing a draft tube at the top of the double-spore mushroom planting house, the draft effect is enhanced, and at the same time, rainwater is prevented from entering.

[0009] Furthermore, the first ventilation window structure includes a frame that can be installed in the wall of the double-spore mushroom planting house. A double sliding plate is provided at the air inlet end of the frame. An air inlet placement box connected to the frame is provided in the frame. A first blower for accelerating air flow is provided in the air inlet placement box. By providing the double sliding plate, it can play a role in ventilation and also reduce the light received during the planting of double-spore mushrooms. Moreover, this structure is simple, convenient for replacement and disassembly, thereby reducing the cost for the planters.

[0010] Furthermore, a slot is provided on one side of the frame. The double sliding plate can be inserted into the slot. An air outlet limiting plate for limiting the first blower is provided in the air inlet placement box. A filter screen plate is provided between the double sliding plate and the air inlet placement box. The double sliding plate can be inserted into the slot, which is convenient for personnel to quickly replace and disassemble. The setting of the filter screen plate is used to reduce the entry of dust.

[0011] Further, a limit nut for limiting the double push-pull plate in the slot is provided at the bottom of the frame. The filter screen plate is inserted into the frame along the top of the frame. Connecting plates connected to the frame are provided on both sides of the frame, and connecting plate fixing bolts that can be inserted into the Agaricus bisporus cultivation room are provided in the connecting plates. The setting of the limit nut is used to limit the double push-pull plate. The setting of the connecting plates and the connecting plate fixing bolts is used to fixedly lock the two ventilation window structures.

[0012] Further, the aperture mesh number range of the filter screen plate is 20 mesh - 30 mesh.

[0013] Further, the structure of the second ventilation window structure is the same as that of the first ventilation window structure.

[0014] Further, a first ventilation window structure that can be sequentially arranged along the wall of the Agaricus bisporus cultivation room is provided in the Agaricus bisporus cultivation room, and a second ventilation window structure that can be sequentially arranged along the wall of the Agaricus bisporus cultivation room is provided in the Agaricus bisporus cultivation room.

[0015] Further, an exhaust pipe communicating with the inside of the Agaricus bisporus cultivation room is provided at the top of the Agaricus bisporus cultivation room. A converging air pipe connected to the exhaust pipe is provided at the air inlet end of the exhaust pipe, and a second blower is provided at the air outlet end of the converging air pipe. Through the setting of the converging air pipe and the second blower, after the second blower is started, the air in the Agaricus bisporus cultivation room can be gathered, thereby accelerating the internal flow and blowing it out to the outside.

[0016] Further, the cross-sectional shape of the exhaust pipe is hook-shaped. The air outlet end of the exhaust pipe with a hook-shaped cross-sectional shape is close to the Agaricus bisporus cultivation room. The cross-sectional shape of the converging air pipe is trumpet-shaped, and the diameter of the air outlet end of the converging air pipe is smaller than the diameter of the air inlet end of the converging air pipe. The exhaust pipe can be installed on the top of the Agaricus bisporus cultivation room through an exhaust pipe bolt. The setting of the exhaust pipe with a hook-shaped cross-sectional shape can prevent rainwater from entering the room along the exhaust pipe during the rainy season.

[0017] The ventilation requirements of the Agaricus bisporus cultivation room are crucial for the growth of mushrooms, which directly affect the growth rate of mycelium, the formation of fruiting bodies, as well as the yield and quality. The following are the detailed ventilation requirements:

[0018] I. Importance of ventilation:

[0019] 1). Oxygen supply: Ventilation can increase the oxygen content in the mushroom house to meet the oxygen demand during the growth of Agaricus bisporus. If the oxygen is insufficient, the caps of the mushroom bodies will become smaller, the mushroom stalks will be slender, the number of deformed mushrooms and dead mushrooms will increase, resulting in a reduction in yield.

[0020] 2) Temperature adjustment: Ventilation can control the temperature in the mushroom house, avoiding adverse effects on mushroom growth caused by excessive or too low temperature. Especially in the high-temperature season, ventilation helps reduce the temperature in the mushroom house and prevent the mycelium from degenerating and turning yellow due to high temperature.

[0021] 3) Humidity control: Ventilation can also help regulate the humidity in the mushroom house, preventing the occurrence of miscellaneous bacteria and pests caused by excessive humidity, and slow growth or malformation of the fruiting bodies caused by too low humidity.

[0022] II. Specific requirements for ventilation:

[0023] 1) Ventilation volume:

[0024] In the initial stage after sowing (within 2 - 3 days), focus on moisture retention and have less ventilation. The relative humidity in the shed should be maintained at 85% - 90%.

[0025] As the mycelium grows (after 3 - 4 days), gradually increase the ventilation volume, but still mainly open the leeward windows.

[0026] When the mycelium covers the surface (after 7 - 10 days), increase the ventilation volume, open all the doors and windows day and night, and reduce the humidity in the mushroom house to 75% - 80%.

[0027] In the fruiting stage, especially after spraying the mushroom-setting water and the appearance of mushroom buds, the ventilation volume should be 3 - 4 times larger than usual to keep the relative humidity in the room at 90% - 95%.

[0028] 2) Ventilation time:

[0029] Open the doors and windows for ventilation for 15 - 20 minutes every morning and evening to remove the waste gas in the mushroom house.

[0030] If the temperature in the mushroom house is higher than 25°C, open the windward and leeward doors and windows for ventilation.

[0031] When promoting mushroom setting and the swelling of the fruiting bodies, continuous large ventilation is required for several days. Open the leeward windows during the day and the front and rear doors and windows at night to increase the temperature difference.

[0032] 3) Ventilation method:

[0033] The mushroom house should be designed with a reasonable layout of ventilation openings and doors and windows for easy ventilation and air exchange.

[0034] The ventilation openings should be set at both the north and south ends of the mushroom house, which is conducive to forming convective wind and improving the ventilation effect.

[0035] The roof can be equipped with exhaust pipes to enhance the exhaust effect and prevent rainwater from entering at the same time.

[0036] 4) Precautions for ventilation

[0037] Avoid direct blowing on the mycelium or fruiting bodies during ventilation to avoid damage.

[0038] After ventilation, the doors and windows should be closed in time to keep the temperature and humidity stable in the mushroom house.

[0039] Under adverse conditions such as high temperature and high humidity or low temperature and low humidity, ventilation management should be strengthened to adjust the environmental conditions in the mushroom house.

[0040] III. Other relevant requirements;

[0041] The mushroom house should face south with north behind, which is beneficial for both ventilation and temperature control.

[0042] The size of the mushroom house is preferably 100 - 200 square meters for the cultivation area. If it is too large, the ventilation in the middle part will be poor; if it is too small, the utilization rate will be low.

[0043] Bed frames should be installed in the mushroom house and placed in the north - south direction to facilitate ventilation and lighting.

[0044] Management passages should be left between the bed frames to facilitate operation and management.

[0045] In summary, the ventilation requirements for the Agaricus bisporus planting house include aspects such as ventilation volume, ventilation time, ventilation method, and ventilation precautions. Reasonable ventilation management can provide good environmental conditions for the growth of Agaricus bisporus, thereby improving the yield and quality.

[0046] Compared with the existing technology, this ventilation device for the Agaricus bisporus planting house can adaptively ventilate the first ventilation window structure and the second ventilation window structure according to factors such as the growth cycle of Agaricus bisporus and ventilation time. And when large - scale ventilation of the Agaricus bisporus planting house is required, through the settings of the first ventilation window structure, the second ventilation window structure and the exhaust pipe, its ventilation effect can be greatly improved, and further, the product and quality of Agaricus bisporus in the planting house can be guaranteed, greatly improving the practicability of this equipment.
