Description

Technical Field

[0001] This utility model belongs to the technical field of edible fungi cultivation greenhouses, specifically a year-round mushroom-growing greenhouse for shiitake mushroom cultivation. Background Technology

[0002] Existing shiitake mushroom cultivation greenhouses are all single-layer greenhouses, and the ventilation openings are all located on the roof, which has the following significant drawbacks:

[0003] Poor environmental control: Single-layer greenhouses are difficult to effectively isolate extreme external climates (such as low temperatures and strong winds), resulting in large fluctuations in temperature and humidity inside the greenhouse, poor heat preservation, and excessive temperature differences will directly affect the growth cycle and quality of shiitake mushrooms; in addition, they are not strong enough to resist snow and wind and are easily damaged.

[0004] Inadequate ventilation design: Ventilation openings are generally located on the roof of the greenhouse, which is conducive to the discharge of heat, but in rainy weather, rainwater backflow can easily cause water accumulation inside the greenhouse, increasing the risk of disease. Utility Model Content

[0005] To address the aforementioned problems, the purpose of this utility model is to provide a year-round mushroom cultivation greenhouse for shiitake mushrooms. Its double-layered design, with ventilation openings located on the inner wall of the greenhouse, effectively solves the problems of poor heat preservation and easy water ingress in traditional greenhouses.

[0006] To achieve the above objectives, the technical solution adopted by this utility model is as follows.

[0007] A year-round mushroom cultivation greenhouse for shiitake mushrooms includes an outer greenhouse and an inner greenhouse. The outer greenhouse surrounds the outer perimeter of the inner greenhouse and the two are spaced apart. The inner greenhouse includes a base frame and a roof. The roof is composed of several adjacent inner roofs connected in an array. Each inner roof has a vertical surface and a sloping surface. The upper end of the vertical surface and the upper end of the sloping surface intersect and connect. The lower end of the vertical surface and the lower end of the sloping surface are respectively located on the base frame. Each vertical surface is provided with an array of upper ventilation openings. The angle between the vertical surface and the sloping surface is an acute angle. The outer greenhouse has windward surfaces extending outward on at least two axial sides for wind protection.

[0008] Furthermore, the base frame is arrayed with telescopic insulation pads, which are used to separate or connect the space between the base frame and the ceiling.

[0009] Furthermore, exhaust fans are arranged in a spaced array on both sides of the inner canopy.

[0010] Furthermore, a mesh screen is installed on the upper ventilation opening.

[0011] Furthermore, the base frame includes vertical support columns and longitudinal horizontal support rods. Several vertical support columns are arranged in a row at horizontal intervals and in a longitudinally spaced array. The longitudinal horizontal support rods are connected to the vertical support columns in the longitudinally spaced array. The bottom sides of the inner top are respectively set on a pair of adjacent longitudinal horizontal support rods.

[0012] Furthermore, the base frame also includes transverse horizontal support rods, with a plurality of transverse horizontal support rods arranged longitudinally at intervals. The two ends of the transverse horizontal support rods are connected to a pair of transversely spaced vertical support columns. The insulation pad is arranged between the pair of longitudinally spaced transverse horizontal support rods, with one end of the insulation pad fixedly connected to one of the transverse horizontal support rods and the other end detachably connected to the other transverse horizontal support rod.

[0013] Furthermore, the inner roof includes inner roof beams and a greenhouse film. The greenhouse film is laid on the inner roof beams, and several inner roof beams are arranged longitudinally at intervals. The inner roof beams are composed of vertical beams and inclined beams connected together. The greenhouse film covers the vertical beams to form the vertical surface, and the inclined beams cover the inclined beams to form the inclined surface. The included angle formed by connecting one end of the vertical beam and one end of the inclined beam is less than 90°. The other end of the vertical beam and the other end of the inclined beam are respectively connected to a pair of relatively spaced longitudinal horizontal support rods.

[0014] Furthermore, a vertical rib is provided on the transverse horizontal support rod, with one end of the vertical rib connected to the inner top beam and the other end connected to the transverse horizontal support rod.

[0015] Furthermore, a lower ventilation duct is provided on at least one of the windward surfaces, the lower ventilation duct passing through the inner canopy as an inlet and outlet, and a curtain is provided on the inlet and outlet.

[0016] Furthermore, an insulation curtain and a sunshade net are sequentially installed around the outer perimeter of the outer canopy.

[0017] This utility model, by adopting the above technical solution, has the following advantages and effects:

[0018] 1. This utility model discloses a year-round mushroom cultivation greenhouse for shiitake mushrooms, which adopts a double-layer composite structure. The cavity formed by the outer and inner greenhouses constitutes a natural heat insulation layer, which can reduce heating energy consumption and significantly reduce heat loss in winter, thereby improving the heat preservation effect. In summer, the upper ventilation opening and lower ventilation duct form convection to accelerate heat dissipation, achieving constant temperature and humidity throughout the year. Furthermore, after experimental verification, when the natural temperature in summer is 40℃, the air temperature at a height of 1.5 meters inside the greenhouse is about 29℃. In winter, when the outside temperature is -15℃, the temperature at a height of 1.5 meters inside the greenhouse is about 6℃. Moreover, the windward airflow surface formed by the windward sides on both sides of the outer greenhouse can disperse wind pressure load. Combined with the array layout of multiple inner roofs in the inner greenhouse, the overall wind resistance level is significantly improved, making it adaptable to harsh weather conditions.

[0019] 2. This utility model provides a year-round mushroom cultivation greenhouse for shiitake mushrooms. The upper ventilation opening is changed from the roof to the inner facade of the greenhouse. The guide slope formed by the acute angle ensures air convection efficiency and prevents rainwater from directly entering, reducing the risk inside the greenhouse. Furthermore, the upper and lower ventilation can utilize the phenomenon of hot air gravity flow to achieve natural ventilation and reduce energy consumption. Attached Figure Description

Detailed Implementation

[0024] The embodiments of this utility model will be described in detail below with reference to the accompanying drawings, so as to better understand the purpose, features and advantages of this utility model. It should be understood that the embodiments shown in the drawings are not intended to limit the scope of this utility model, but are only for illustrating the essential spirit of the technical solution of this utility model.

[0025] like Figures 1-3 As shown. This utility model provides a year-round mushroom cultivation greenhouse for shiitake mushrooms, including an outer greenhouse 2 and an inner greenhouse. The outer greenhouse 2 surrounds the outer perimeter of the inner greenhouse and the two are spaced apart. The inner greenhouse includes a base frame 3 and a roof. The roof is composed of several inner roofs connected in an adjacent array. Each inner roof has a vertical surface and a sloping surface. The upper end of the vertical surface and the upper end of the sloping surface intersect and connect. The lower end of the vertical surface and the lower end of the sloping surface are respectively set on the base frame 3. Each vertical surface is provided with an array of upper ventilation openings 311. The upper ventilation openings 311 are rectangular windows and are arranged along the longitudinal direction of the vertical surface. The angle between the vertical surface and the sloping surface is an acute angle. The outer greenhouse 2 has windward surfaces extending outward on at least two axial sides for wind protection. The outer greenhouse 2 and the inner greenhouse are nested together to further provide heat preservation and wind resistance. The sequential connection of several inner roofs facilitates the setting of the upper ventilation openings 311 on the vertical surface. Setting the upper ventilation openings 311 on the vertical surface can prevent external rainwater from easily entering the inner greenhouse.

[0026] Specifically, the outer canopy 2 includes an upper frame 21, a lower frame 22, and a plastic film. Both the upper frame 21 and the lower frame 22 are covered with plastic film on their outer perimeter. The upper frame 21 has an arched structure, with both ends connected to the sides of the inner canopy's base frame 3. The upper end of the lower frame 22 is connected to the outer perimeter of the base frame 3, while the lower end is buried underground. The lower end of the lower frame 22 slopes outwards and is covered with plastic film to form a windward surface. This windward surface is an inclined slope to reduce wind resistance.

[0027] Each inner canopy is 6 meters wide. Three inner canopies are installed on the base frame 3 inside the inner canopy. Each inner canopy is about 1.8 meters high. The base frame 3 is about 3 meters high. The outer canopy is about 5.5 meters high. The bottom of the windward side of the outer canopy is at least 1 meter away from the top of the inner canopy. The top of the windward side is basically flush with the top of the base frame 3.

[0028] Of course, as a preferred option, the upper ventilation openings 311 can also be arranged in a longitudinally spaced array along the facade.

[0029] Furthermore, to improve the insulation effect of the inner shed, a telescopic insulation pad 4 is arrayed on the base frame 3. The insulation pad 4 is used to separate or connect the space between the base frame 3 and the inner roof. The insulation pad 4 extends or rolls along the longitudinal direction of the base frame 3. When insulation is required, the insulation pad 4 is stretched longitudinally in sequence, covering the top of the base frame 3 to separate the space between the base frame 3 and the inner roof. When separation is not required, the insulation pad 4 can be rolled or contracted to a certain width and laid on the base frame 3. The insulation pad 4 is preferably an insulation cotton pad. The telescopic insulation cotton pad can be unfolded or rolled up as needed to separate or connect the shed space.

[0030] Furthermore, to facilitate ventilation within the inner shed, exhaust fans 5 are arranged in a staggered array along both longitudinal sides of the inner shed. The exhaust vents of the exhaust fans 5 extend outwards from the outer shed. Exhausting air through the exhaust fans 5 accelerates air circulation within the inner shed. The exhaust fans 5 are linked with the upper vent 311, at which point air enters through the upper vent 311 and exhausts through the exhaust fans 5, forming a "negative pressure suction + positive pressure air supply" cycle. This accelerates the removal of harmful gases, inhibits the growth of pathogens, and improves the appearance of the shiitake mushrooms.

[0031] Furthermore, a mesh screen is installed on the upper vent 311. The mesh screen can prevent birds or other insects from entering the inner shed through the upper vent 311.

[0032] Furthermore, the base frame 3 includes vertical support columns 33 and longitudinal horizontal support rods 32. Several vertical support columns 33 are arranged in a row at horizontal intervals and in a row at longitudinal intervals. The longitudinal horizontal support rods 32 are connected to the vertical support columns 33 in the longitudinal interval array. The bottom of the two sides of the inner top are respectively set on a pair of adjacent longitudinal horizontal support rods 32.

[0033] Specifically, in this invention, the vertical support columns 33 are arranged in four rows at horizontal intervals, with the horizontal intervals matching the width of each inner ceiling, and the longitudinal intervals of each row are approximately 3 meters. The longitudinal horizontal support rods 32 located in the middle simultaneously support the vertical and inclined surfaces of the adjacent inner ceiling, while the longitudinal horizontal support rods 32 located at the edges connect to and support the vertical or inclined surfaces. The upper frame 21 of the outer canopy 2 is connected at both ends to the pair of outermost longitudinal horizontal support rods 32, and the upper end of the lower frame 22 is connected to the outermost longitudinal horizontal support rods 32.

[0034] Furthermore, the base frame 3 also includes transverse horizontal support rods 34, a plurality of transverse horizontal support rods 34 are longitudinally spaced, and the two ends of the transverse horizontal support rods 34 are connected to a pair of transversely spaced vertical support columns 33. An insulation pad 4 is provided between the pair of longitudinally spaced transverse horizontal support rods 34, one end of the insulation pad 4 is fixedly connected to one of the transverse horizontal support rods 34, and the other end is detachably connected to the other transverse horizontal support rod 34.

[0035] Specifically, the top ends of the horizontally adjacent vertical support columns 33 are respectively connected to the two ends of the horizontal support rods 34, and the longitudinally adjacent horizontal support rods 34 are provided with insulation pads 4. One end of the insulation pads 4 can be removed from one of the horizontal support rods 34 and rolled up to the outer periphery of the other horizontal support rod 34.

[0036] Furthermore, the inner roof includes inner roof beams 31 and a greenhouse film. The greenhouse film is laid on the inner roof beams 31. Several inner roof beams 31 are arranged longitudinally at intervals. The inner roof beams 31 are composed of vertical beams and inclined beams connected together. The greenhouse film covers the vertical beams to form a vertical surface, and the greenhouse film covers the inclined beams to form a sloping surface. The included angle formed by the connection of one end of the vertical beam and one end of the inclined beam is less than 90°. The other end of the vertical beam and the other end of the inclined beam are respectively connected to a pair of relatively spaced longitudinal horizontal support rods 32.

[0037] Specifically, the vertical beam and the inclined beam are made by bending a steel pipe. One end of the inclined beam can be a straight steel pipe or an arc-shaped steel pipe. When it is a straight steel pipe, the inclined surface is a straight surface. When it is an arc-shaped steel pipe, the inclined surface is an arc-shaped surface.

[0038] Each inner top beam 31 is also provided with a vertical rib beam 35. One end of the vertical rib beam 35 is connected to the inner top beam 31, and the other end is connected to the horizontal support rod 34. The vertical rib beam 35 is used to support the inner top beam 31 to achieve the stability of the inner top.

[0039] As a preferred embodiment, the vertical ribs 35 include at least three, with the bottoms of the three vertical ribs 35 connected together and connected to the transverse horizontal support rod 34, and the tops of the three vertical ribs 35 extending outward to form a fan-shaped distribution and connected to the inclined crossbeam of the inner top bone beam 31.

[0040] Furthermore, to facilitate ventilation of the lower part of the inner canopy and access to and from the inner canopy, a lower ventilation duct (not shown in the figure) is provided on at least one windward side. The lower ventilation duct runs through the inner canopy and serves as both an entrance and exit, and is covered with a curtain. When the curtain of the lower ventilation duct is opened, airflow can enter through the lower ventilation duct and exit through the upper ventilation opening 311, forming convection. The width of the entrance and exit is approximately 3 meters, and the height is approximately 2.5 meters to facilitate the entry and exit of mechanical vehicles.

[0041] Furthermore, an insulation curtain and a shade net 1 are sequentially installed around the outer perimeter of the outer canopy 2. The shade net 1 is located around the insulation curtain and is spaced apart from the insulation curtain. The insulation curtain is an automatically lifting straw curtain, which is laid around the outer perimeter of the outer canopy 2 and controlled by an electric hoist for rolling and lowering.

[0042] This utility model discloses a year-round mushroom cultivation greenhouse for shiitake mushrooms. Due to the adoption of a double-layer composite structure, the cavity formed by the outer and inner greenhouses constitutes a natural heat insulation layer, achieving constant temperature and humidity throughout the year. The upper ventilation opening is changed from the roof to the inner greenhouse facade, and the guiding slope formed by the acute angle ensures air convection efficiency while preventing direct rainwater intrusion.
