Edible mushroom cultivation box

Abstract

This utility model discloses an edible mushroom cultivation box, belonging to the field of cultivation boxes. The cultivation box includes a box body, a fan, an air supply structure, and an air supply adjustment mechanism. By replacing the electronic sensing system with a mechanized structure, the air supply structure and adjustment mechanism automatically open and close the air vents of each layer of mushroom bags within the box. This forms a central airflow that is refracted by a serrated guide plate and an adjustable air vane and then evenly distributed to each shelf, adapting to changes in the oxygen demand of the mushroom bags at different growth stages. This device completely eliminates electronic sensors, solving the problems of slow response, poor uniformity, and high maintenance costs of traditional equipment through a purely mechanical structure. It ensures real-time response to the growth status of the mushroom bags in high-humidity environments, stable operation, uniform environment, and low maintenance costs.

Description

Technical Field

[0001] This utility model relates to the field of edible fungi cultivation technology, specifically to an edible fungi cultivation box. Background Technology

[0002] Edible fungi refer to large, edible mushrooms (macrofungi), commonly known as mushrooms.

[0003] In edible mushroom production, the incubation of spawn bags is a crucial step determining yield and quality. Currently, most mainstream incubation boxes employ electronic control systems. These systems collect environmental parameters via built-in carbon dioxide sensors. When the carbon dioxide level exceeds a set threshold, a PLC controller drives the fan for adjustment. However, electronic sensors can only monitor air conditions and cannot detect changes in spawn bag weight, resulting in a delayed response. When the spawn bags enter the logarithmic growth phase and oxygen demand surges, the system cannot adjust airflow according to spawn bag growth, creating a growth bottleneck. Furthermore, using only fixed bottom air vents makes it difficult to ensure environmental uniformity within the incubation box, leading to uneven growth rates and severely inhibiting spawn bag growth. Additionally, the incubation box operates in a high-humidity environment, resulting in high maintenance costs for the electronic control system, a high sensor failure rate, and overall high maintenance costs.

[0004] To address the above problems, this utility model provides an edible fungus cultivation box. Utility Model Content

Detailed Implementation

[0020] 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.

[0021] Please see Figures 1 to 6 One embodiment provided by this utility model: An edible fungus cultivation box includes a box body 100, a fan 200, two sets of symmetrically placed air supply structures 300, and an air supply adjustment mechanism 400. Two air outlet holes 101 are symmetrically and equidistantly opened on one side of the air outlet of the housing 100, and several ventilation holes 103 are opened between the two air outlet holes 101 for carbon dioxide emission and air exchange; two air inlet holes 102 are symmetrically and equidistantly opened on one side of the air inlet of the housing 100, and a fan 200 is provided on one side of the air inlet to introduce external air; the air outlet 301 is inserted into the air outlet hole 101, and the air inlet 302 is inserted into the air inlet hole 102. Two air supply structures 300 are symmetrically arranged on the housing 100. Fan 200, the output end of fan 200 acts on air inlet 302, and is used to transmit air power to air supply duct 303.

[0022] The air supply structure 300 includes an air outlet 301, an air inlet 302, an air supply duct 303, and an air outlet 304. The air outlet 301 is connected to an air outlet through hole 101, and the air inlet 302 is connected to an air inlet through hole 102, so that the air force of the fan 200 only flows within the air supply duct 303, generating a central airflow that flows along the height direction of the box in the air supply duct 303. One end of the guide plate 3041 is fixedly installed on the air outlet 304, and the guide plate 3041 is used to transmit the air force in the air supply duct 303 to each layer of the placement rack 401. The other end of the guide plate 3041 is serrated. After the central airflow hits the guide plate 3041, it forms turbulence and spreads evenly on the placement rack 401, so as to achieve uniform airflow to the mushroom bags on the same layer of the placement rack 401, and further ensure the growth status. The bottom of the air supply duct 303 is curved to prevent carbon dioxide buildup.

[0023] The air supply adjustment mechanism 400 includes an air vane 404 and a support plate 402. The support plate 402 is fixedly installed on the inner wall of the housing 100. The support plate 402 is connected to the placement rack 401 through multiple sets of springs 403 to support the placement rack 401. The placement rack 401 is hollow to ensure vertical airflow penetration and is used to place the mushroom bags. An adjustment component 405 is connected to the bottom of the placement rack 401 to control the opening and closing angle of the air vane 404. One side of the air deflector 404 covers the air outlet 304. One end of the air deflector 404 is provided with an air deflector shaft 4042, which is fixedly connected to the inner wall of the air supply duct 303. The other end is serrated and cooperates with the guide plate 3041 to form turbulence, so that the airflow is evenly distributed on the placement rack 401. The air deflector 404 is used to control the opening and closing angle of the air outlet 304 to adjust the air intake volume. The adjustment component 405 includes a connecting bar 4056, on which a sliding groove 4055 is provided. A sliding shaft 4054 slides in the sliding groove 4055 along the upward or downward direction of the groove. The sliding groove 4055 is arc-shaped to further conform to the movement trajectory. One end of the connecting plate 4053 is connected to the sliding shaft 4054, and the sliding shaft 4054 can rotate relative to the connecting plate 4053. The other end is connected to the air plate 404, thereby driving the air plate 404 to rotate around the air plate rotation shaft 4042, so as to realize the angle opening and closing adjustment of the air plate 404. The compressible stroke of the spring 403 is greater than the range of motion of the adjusting component 405, providing redundant space for the mechanism's movement and ensuring reliable transmission of weight perception.

[0024] Working principle: In the initial state (without mushroom bags placed), the placement rack 401 is subjected to the elastic force of the spring 403. At this time, the height of the placement rack 401 is still higher than the height required for the adjustment component 405 to be balanced (i.e., the opening angle of the air vane 404 is 0°, and it is in contact with the inner wall 303 of the air supply duct). Therefore, the connecting strip 4056 is displaced upward. Due to the bottom limit of the sliding groove 4055, the sliding shaft 4054 will drive the connecting plate 4053 to move upward. The connecting plate 4053 drives the air vane 404 to rotate around the air vane rotating shaft 4042, thereby opening the air vane 404 upward at a certain angle to maintain air circulation in the box 100 and ensure the indoor environment when no mushroom bags are placed.

[0025] In the early stage of mycelial growth, the mycelial bag is placed on the placement rack 401. At this time, the spring 403 is further compressed, and the height of the placement rack 401 decreases. As a result, the connecting strip 4056 moves downward, which will drive the connecting plate 4053 to move downward, causing the air plate 404 to rotate around the air plate pivot 4042. At this time, the opening and closing angle of the air plate 404 is 0°, that is, the air plate 404 is completely in contact with the inner wall of the air supply duct 303 and covers the air outlet 304. At this time, only the ventilation hole 103 is used to communicate with the outside air, and no additional air is delivered to the box 100.

[0026] As the spawn bag enters its rapid growth phase, its weight increases. At this time, the spring 403 is further compressed, causing the placement rack 401 to drop in height and the connecting strip 4056 to move downward. Meanwhile, the sliding shaft 4054 moves upward within the groove 4055, thereby causing the connecting plate 4053 to move upward. The connecting plate 4053 then causes the air vane 404 to rotate around the air vane pivot 4042, thus opening the air vane 404 at a certain angle. At this point, the central airflow is refracted by the guide plate 3041 to the spawn bag area of ​​this layer.

[0027] When the spawn bag enters the maturity stage, the weight of the spawn bag increases further. At this time, the spring 403 is compressed to its maximum stroke. At this time, as described in the above process of "the spawn bag entering the rapid growth stage", the air deflector 404 is opened to its maximum angle. At this time, the central airflow is refracted to the spawn bag area of ​​this layer by the guide plate 3041.

[0028] After the spawn bags mature, they are removed from the placement rack 401. The weight of the bags releases the previously compressed spring 403, causing it to spring back and push the placement rack 401 upwards. As the rack rises, the rigidly connected connecting bar 4056 also moves upwards. Similar to the initial working principle, the rising connecting bar 4056 causes the sliding shaft 4054 to slide downwards within the sliding groove, thereby driving the air vane 404 to rotate around the air vane shaft 4042 via the connecting plate 4053, gradually decreasing its opening angle. Once the spawn bags are completely removed, the spring 403 pushes the placement rack 401 back to its initial position. After resetting, the air supply adjustment mechanism 400 returns to its initial state, preparing for the next cultivation cycle.

[0029] Since each mushroom bag has a fixed weight, a spring of appropriate specifications can be selected to adapt to the weight of the mushroom bag at different stages, thereby adjusting the opening and closing angle of the air baffle 404. The mechanical structure design of this incubator fully considers the characteristics of the edible fungi production environment. All moving parts are made of 304 stainless steel, and the surfaces of key friction pairs (such as the sliding shaft 4054) are coated with a 0.1 mm thick polytetrafluoroethylene coating to achieve self-lubrication.

[0030] In the early stages of mycelial growth, the substrate requires a high-temperature, low-oxygen environment. Excessive air circulation will lower the temperature within the container by 100°C. As the substrate enters its rapid growth phase, the required temperature decreases while the oxygen demand increases (oxygen consumption increases by 35% for every 100g increase in mycelial biomass). When the substrate enters its mature stage, the required temperature decreases further while the oxygen demand reaches its maximum. At the same time, a large amount of carbon dioxide is produced during this stage, and the accumulation of carbon dioxide will affect the development of the substrate.

[0031] Therefore, this invention adjusts the airflow based on the weight of the mushroom bags to meet the growth requirements. Simultaneously, a multi-layered rack 401 is installed inside the housing 100 to adjust the airflow accordingly for mushroom bags of different heights that exhibit varying growth rates. When the ambient temperature and humidity are suitable, open the box door and place the mushroom bags on the placement rack 401. The growth of the mushroom bags can be directly observed through the glass viewing window of the box door, even after the door is closed. When the mushroom bags are first placed, the opening angle of the fan plate 404 is 0 degrees to ensure the temperature and humidity inside the box 100. At this time, the ventilation hole 103 provides the amount of oxygen required for the growth of the mushroom bags. As the mushroom bags grow, their weight gradually increases, and the opening angle of the fan plate 404 also gradually increases. At this time, as the opening angle of the fan plate 404 increases, the airflow from the central air outlet 304 is refracted by the guide plate 3041 to the mushroom bag area of ​​this layer, and the airflow gradually increases, realizing the appropriate airflow adjustment for mushroom bags at different growth stages.

[0032] It will be apparent to those skilled in the art that this invention is not limited to the details of the exemplary embodiments described above, and that it can be implemented in other specific forms without departing from the spirit or essential characteristics of this invention. Therefore, the embodiments should be considered illustrative and non-limiting in all respects, and the scope of this invention is defined by the appended claims rather than the foregoing description. Thus, it is intended that all variations falling within the meaning and scope of equivalents of the claims be included within this invention. No reference numerals in the claims should be construed as limiting the scope of the claims.
