Description

Technical Field

[0001] This utility model relates to the field of Hericium erinaceus cultivation technology, specifically to a ventilation device for Hericium erinaceus cultivation. Background Technology

[0002] Hericium erinaceus is a rare edible fungus with both nutritional and medicinal value. It is named for its resemblance to a monkey's head. Hericium erinaceus is a saprophytic fungus that grows naturally on the dead wood of broad-leaved trees. Artificial cultivation requires simulating its natural growing conditions.

[0003] When cultivating Hericium erinaceus in artificial cultivation experimental chambers, ventilation is usually required. If ventilation is not carried out in time, excessive accumulation of gases such as carbon dioxide inside the cultivation chamber will affect the growth of Hericium erinaceus. Existing ventilation devices usually use air intake fans to directly supply air into the cultivation chamber and exhaust gases such as carbon dioxide through exhaust vents to achieve the effect of ventilation for Hericium erinaceus inside the cultivation chamber. However, this ventilation method of directly blowing air into the Hericium erinaceus can damage it. In addition, the air intake fans can only intake air locally and the operating time of the air intake fans is fixed, which may lead to incomplete ventilation inside the cultivation chamber.

[0004] Therefore, a ventilation device for growing Hericium erinaceus is proposed to solve the problems mentioned above. Utility Model Content

[0005] To address the shortcomings of existing technologies, this utility model provides a ventilation device for growing Hericium erinaceus, which can solve problems such as damage to Hericium erinaceus caused by air intake fans directly blowing air onto the mushrooms.

[0006] To achieve the above objectives, this utility model provides the following technical solution: it includes a frustum-shaped planting chamber and two ventilation openings that penetrate through the outside of the frustum-shaped planting chamber. The two ventilation openings are symmetrically distributed. A cover plate is provided at the lower end of the frustum-shaped planting chamber, and an annular fixing frame is fixedly connected to the outside of the frustum-shaped planting chamber. A ventilation mechanism is provided inside the frustum-shaped planting chamber. The ventilation mechanism includes a ventilation pipe for conveying air, an air storage tank for storing air, and an air intake fan for filling air.

[0007] Preferably, the ventilation duct is located at the lower end of the air storage tank, and several ventilation ducts are connected to the air storage tank. Several air inlet pipes are provided at the upper end of the air storage tank, and one end of each air inlet pipe is connected to the inside of the air storage tank.

[0008] Preferably, the distance between two adjacent ventilation ducts is equal, and the ventilation ducts and the air inlet pipes are staggered, and the ventilation ducts and the air inlet pipes are not on the same horizontal line.

[0009] Preferably, the ventilation duct is Z-shaped, and the included angle between adjacent ventilation ducts is α, where 50° > α > 40°.

[0010] Preferably, the frustum-shaped planting chamber is upright, and the inner diameter of the lower half of the frustum-shaped planting chamber is smaller than the inner diameter of the upper half.

[0011] Preferably, a motor is provided inside the air intake pipe, and the output end of the motor is fixedly connected to the air intake fan, and the lower ends of several air intake pipes are all connected through the frustum-shaped planting chamber.

[0012] Preferably, a connecting plate is fixedly connected to the end of the motor away from the output end, and the connecting plate is fixedly connected to the inside of the air intake pipe.

[0013] Compared with the prior art, this utility model provides a ventilation device for the cultivation of Hericium erinaceus, which has the following beneficial effects: 1. By setting the ventilation ducts in a Z-shape, the problem of air blowing directly onto the monkey head mushrooms and damaging them is prevented, thus improving the stability of ventilation.

[0014] 2. By setting the planting chamber in a frustum shape, the residual carbon dioxide at the top can flow naturally downwards along the chamber walls, improving ventilation efficiency. Attached Figure Description

[0017] The technical solutions of the present utility model will be clearly and completely described below with reference to the accompanying drawings of the embodiments. Obviously, the described embodiments are only some embodiments of the present utility model, and not all embodiments. Based on the embodiments of the present utility model, all other embodiments obtained by those of ordinary skill in the art without creative effort are within the protection scope of the present utility model. Example

[0018] Please see Figure 1 - Figure 4 The ventilation device for growing Hericium erinaceus in this embodiment includes a frustum-shaped growing chamber 1 and two ventilation openings 2 that are opened through the outside of the frustum-shaped growing chamber 1. The two ventilation openings 2 are symmetrically distributed. A cover plate is provided at the lower end of the frustum-shaped growing chamber 1, and an annular fixing frame 3 is fixedly connected to the outside of the frustum-shaped growing chamber 1. A ventilation mechanism is provided inside the frustum-shaped growing chamber 1. The ventilation mechanism includes a ventilation pipe 4 for conveying air, an air storage tank 9 for storing air, and an air intake fan 6 for filling air. Ventilation duct 4 is located at the lower end of air storage tank 9. Several ventilation ducts 4 are connected to air storage tank 9. Several air inlet pipes 5 are provided at the upper end of air storage tank 9. One end of several air inlet pipes 5 is connected to the inside of air storage tank 9. The distance between two adjacent ventilation ducts 4 is equal. Several ventilation ducts 4 and several air inlet pipes 5 are staggered and the ventilation ducts 4 and air inlet pipes 5 are not on the same horizontal line. The ventilation duct 4 is Z-shaped, and the included angle between adjacent ventilation ducts is α, with 50° > α > 40°. The use of motor 7 to drive air intake fan 6 to rotate, thereby supplying air into the frustum-shaped planting chamber 1, and the use of ventilation vent 2 to discharge carbon dioxide accumulated inside the frustum-shaped planting chamber 1 are both existing technologies and therefore not described in detail in this embodiment. As a typical aerobic fungus, Hericium erinaceus (monkey head mushroom) has extremely high oxygen requirements during its growth and development, while continuously producing carbon dioxide and metabolic waste gases. When the oxygen concentration in the environment is insufficient or harmful gases accumulate, ventilation is essential; otherwise, mycelial growth, fruiting body morphology, and yield will be severely affected. In this case, the operator places the Hericium erinaceus on the upper part of the support plate inside the frustum-shaped planting chamber 1 and starts the motor 7. The motor 7 rotates simultaneously, driving the intake fan 6 at the output end to rotate synchronously. The rotating blades of the intake fan 6 create suction on the air in front of the blades. The operator then starts the motor 7, which in turn drives the intake fan 6 at the output end to rotate synchronously. The staggered distribution of ventilation duct 4 and air inlet pipe 5 can prevent air from being directly discharged from the opposite ventilation duct 4 when it first enters the inner side of the air storage tank 9, which would result in a problem of low gas utilization due to the straight in and out of the gas. When the air inlet pipe 5 continuously fills the inner side of the air storage tank 9 with fresh air, when too much air accumulates inside the air storage tank 9, the air will enter the inner side of the frustum-shaped planting chamber 1 through the ventilation duct 4 set at the upper end of the air storage tank 9. The ventilation duct 4 is set in a Z-shape, and the included angle between adjacent ventilation ducts is α, and 50° > α > 40°. The flesh of the lion's mane mushroom is delicate. If a straight pipe is used for air supply, the airflow generated by the fan will impact the local mushroom body at high speed along a straight line, which can easily damage the lion's mane mushroom. The Z-shaped structure of the ventilation duct 4 buffers and slows down the gas flow when it enters the inner side of the duct in a straight line, preventing direct airflow from damaging the monkey head mushrooms and improving ventilation stability. Since the carbon dioxide produced by the monkey head mushrooms is denser than air, it accumulates in the lower half of the frustum-shaped cultivation chamber 1. As fresh air is continuously delivered to the inner side of the frustum-shaped cultivation chamber 1 through the ventilation duct 4, it pushes the carbon dioxide produced by the monkey head mushrooms towards the outer side of the chamber. Two ventilation openings 2 on the outside of the truncated cone-shaped planting chamber 1 discharge into the external environment, thereby achieving ventilation and air exchange inside the chamber. When watering the monkey head mushrooms is required, the operator slides the trapezoidal baffle on the outside of the truncated cone-shaped planting chamber 1 upwards and uses a handheld water hose to water the mushrooms. Under normal conditions, the trapezoidal baffle is in a closed state. This truncated cone-shaped planting chamber 1 is suitable for small-scale planting experiments. By observing the effect of this ventilation method, the size of the truncated cone-shaped planting chamber 1 can be modified to adapt to large-scale planting.

[0019] The frustum-shaped planting chamber 1 is set upright, and the inner diameter of the lower half of the frustum-shaped planting chamber 1 is smaller than the inner diameter of the upper half; A motor 7 is installed inside the air intake pipe 5. The output end of the motor 7 is fixedly connected to the air intake fan 6, and the lower ends of several air intake pipes 5 are all connected through the frustum-shaped planting chamber 1. A connecting plate 8 is fixedly connected to the end of the motor 7 away from the output end, and the connecting plate 8 is fixedly connected to the inside of the air intake pipe 5. In this method, by setting the frustum-shaped planting chamber 1 upright and making the inner diameter of the lower half of the frustum-shaped planting chamber 1 larger than the inner diameter of the upper half, the carbon dioxide produced by the monkey head mushroom during respiration will diffuse to the lower end of the frustum-shaped planting chamber 1. The space of the upright frustum, which is wide at the bottom and narrow at the top, allows the hot air at the bottom to flow naturally downward along the chamber wall. Because the lower half of the space is larger, a stable diffusion effect is achieved, avoiding the formation of dead corners where hot air accumulates at the bottom. At the same time, if combined with a ventilation mode of bottom air intake and top air exhaust, gases such as carbon dioxide can be quickly discharged along the natural flow direction of the inner wall of the frustum-shaped planting chamber 1. Compared with the traditional planting chamber of equal width, this ventilation method reduces the output energy consumption of the motor 7, thereby improving the ventilation efficiency. By fixing the output end of the motor 7 to the air intake fan 6, the rotation of the motor 7 can achieve the effect of ventilation inside the frustum-shaped planting chamber 1. By fixing the connecting plate 8 to the motor 7 and fixing the connecting plate 8 to the inside of the air intake pipe 5, the position of the motor 7 can be fixed to prevent the motor 7 from shaking when rotating, thus improving the stability of the structure. In addition, a filter plate is fixedly connected to the inner side of the upper end of the air intake pipe 5. The filter holes in the filter plate can intercept impurities in the air larger than the filter holes at one end of the filter plate, thus achieving the effect of filtering impurities in the air and preventing impurities in the air from flowing into the frustum-shaped planting chamber 1, thereby affecting the growth of the monkey head mushroom.

[0020] The working principle of the above embodiments is as follows: During use, the operator starts the motor 7, which drives the air intake fan 6 at the output end to rotate synchronously. When the air intake pipe 5 continuously fills the air storage tank 9 with fresh air, when too much air accumulates inside the air storage tank 9, the air will enter the inner side of the frustum-shaped planting chamber 1 through the ventilation pipe 4 set at the upper end of the air storage tank 9. The carbon dioxide produced by the monkey head mushroom during respiration will diffuse to the lower end of the frustum-shaped planting chamber 1. With the air intake fan 6 in conjunction with the bottom air intake and top air exhaust ventilation mode, carbon dioxide and other gases can be quickly discharged along the natural flow direction of the inner wall of the frustum-shaped planting chamber 1, achieving the effect of ventilation and air exchange inside the frustum-shaped planting chamber 1.

[0021] The installation, connection, or setting methods disclosed in this embodiment are all common mechanical connection methods. As long as they can achieve their beneficial effects, they can be implemented. Therefore, this embodiment will not elaborate on their specific structural composition and working principle.

[0022] Although embodiments of the present invention have been shown and described, it will be understood by those skilled in the art that various changes, modifications, substitutions and alterations can be made to these embodiments without departing from the principles and spirit of the present invention, the scope of which is defined by the appended claims and their equivalents.
