Description

Technical Field

[0001] This invention relates to the field of mushroom cultivation technology, specifically to a detachable and mobile automatic moisture-retaining production box for mushrooms. Background Technology

[0002] Edible mushroom cultivation equipment is a type of specialized equipment that enables intensive cultivation of mushrooms through multi-layer three-dimensional arrangement. The equipment is usually equipped with a fully automated control system that integrates constant temperature and humidity environment control, intelligent water replenishment and ventilation, etc. It can stably meet the year-round continuous cultivation needs of major edible mushroom varieties such as enoki mushrooms, crab mushrooms, shiitake mushrooms and oyster mushrooms, and has become the core basic equipment in the large-scale edible mushroom production process.

[0003] Existing edible mushroom cultivation equipment using closed-loop chain drive circulating cultivation equipment has been widely used. This type of equipment can drive the cultivation box to achieve full-path circulation through chain drive, which can ensure that the mushrooms can obtain uniform moisture and ventilation during the cultivation process. For example, Chinese patent CN202422518657.9 proposes a three-dimensional fully automatic edible mushroom cultivation machine, which includes two sets of frame components, a support frame with a mushroom stick placement area, and a drive component for driving the support frame to move. The frame components are equipped with several rotatable sprockets arranged in a serpentine pattern and matching chains. Both ends of the support frame can be rotatably fixed between the two sets of chains, and move back and forth in a serpentine pattern with the chains. However, this type of circulating cultivation equipment requires a large number of water mist nozzles to be installed inside the equipment in order to replenish and moisturize the mushrooms. Although it can achieve water replenishment coverage of the entire equipment area, the continuous water mist spraying will significantly increase the humidity of the surrounding environment, keeping the entire equipment in a high-humidity condition for a long time. This can easily cause corrosion and failure of the transmission structure and electrical components, greatly shortening the service life of the equipment. At the same time, the large number of nozzles and supporting pipelines also significantly increases the manufacturing cost of the equipment and the difficulty of later operation and maintenance. Furthermore, this support frame uses a hook-type structure connected to the chain. During the operation of the support frame loaded with mushroom sticks, it is easy to slip, move, or even fall off due to the vibration and turning impact of the circulating transmission. The equipment's operational stability is insufficient. Moreover, the hook-type structure cannot be easily disassembled when mushrooms are being cultivated in the support frame. Disassembly and assembly operations require the entire mushroom stick to be transferred, which is inefficient. Summary of the Invention

[0004] (a) Technical problems to be solved To address the shortcomings of existing technologies, this invention provides a detachable mobile automatic moisture-retaining production box for mushrooms. It features efficient and low-consumption water replenishment, stable connection of the bearing unit, and convenient and efficient disassembly, assembly, and maintenance. This solves the problems of existing equipment where the water replenishment system is prone to causing high humidity corrosion and high cost, as well as the poor operational stability of the bearing unit connection structure and inconvenient disassembly, assembly, and maintenance.

[0005] (II) Technical Solution To achieve the aforementioned goals of efficient and low-consumption water replenishment, stable connection of the supporting unit, and convenient and efficient disassembly, assembly, and maintenance, this invention provides the following technical solution: a detachable mobile automatic moisture-retaining production box for mushrooms, comprising a support frame, on both sides of which a drive gear and two or more sets of driven gears are rotatably mounted, and chains mesh between the driven gears and drive gears on both sides. Two or more sets of pins are equidistantly mounted on the chain along its length direction, and a cultivation box is also provided on the support frame. Bearing seats are fixedly provided on both sides of the cultivation box. The bearing housing has a shaft hole machined inside to accommodate the pin. A clearance opening is provided at the bottom of the shaft hole along its radial direction, penetrating the bearing housing vertically. The pin is aligned and installed into the shaft hole through the clearance opening in the vertical direction. A quick-release bushing is assembled between the pin and the shaft hole. The quick-release bushing is rotatably connected to the pin. A snap-fit ​​plate is provided between the quick-release bushing and the incubator to fix the quick-release bushing in the shaft hole. A water replenishment platform is also provided below the drive gear. A nozzle for replenishing water to the bottom surface of the incubator that moves to the drive gear is fixedly installed in the water replenishment platform.

[0006] Preferably, the chain engages with the drive gear in a vertical tangential direction, and engages with the drive gear in a horizontal tangential direction. The water replenishment platform is positioned below the drive gear in a vertical tangential direction, and the spray direction of the nozzle is parallel to and upwards from the vertical tangential direction of the drive gear.

[0007] Preferably, the incubator includes side plates disposed opposite to each other on both sides and a bottom connecting frame fixedly connected between the two side plates. A mesh cloth for supporting mushrooms is fixedly mounted on the connecting frame. The bearing seat is fixedly connected to the outside of the side plate. The quick-release bushing is axially inserted into the shaft hole from the inside of the incubator. The snap-fit ​​plate is disposed at one end of the quick-release bushing near the inside of the side plate. A snap-fit ​​buckle is fixedly provided on the snap-fit ​​plate. An arc-shaped snap-fit ​​groove with the shaft hole as the center is opened on the side plate. The snap-fit ​​buckle can rotate with the snap-fit ​​plate around the axis of the shaft hole and engage in the arc-shaped snap-fit ​​groove to restrict the axial movement of the quick-release bushing.

[0008] Preferably, both ends of the water replenishment platform are fixedly connected to the support frame, and both ends of the water replenishment platform are also fixedly and sealed with an inlet pipe and an outlet pipe. A water pump is connected to the outside of the inlet pipe. The inlet pipe is arranged to pass through the water replenishment platform laterally, and two or more sets of nozzles are arranged at equal intervals along the length of the inlet pipe. The spray direction of the nozzles is perpendicular to the bottom surface of the incubator.

[0009] Preferably, an arc-shaped spray plate is also fixedly installed on the water replenishment platform. The spray plate is positioned above the water inlet pipe. The center of the arc of the spray plate is the center of the drive gear, and the radius of the arc is greater than the rotation radius of the incubator along the drive gear. Two or more sets of nozzles are arranged equidistantly along the axial direction of the spray plate and the arc axis. The spray plate is machined with drain holes that allow the water accumulated on its surface to flow back into the water replenishment platform. Two or more sets of drain holes are machined on the spray plate.

[0010] Preferably, the chain consists of two or more sets of links, and the pin is fixedly installed at the connection between each set of links. The width of the clearance opening is greater than the diameter of the pin and less than the diameter of the quick-release bushing. The driven gear is rotatably assembled in two or more layers along the height of the support frame. The driving gears on both sides are located at the bottom of the support frame. The chain moves horizontally through each layer of driven gears and then turns upward. When the chain moves to the top driven gear, it moves vertically downward to the driving gear. The driving gear is coaxially fixedly connected to a drive gear, and the drive gear is driven by a drive motor.

[0011] Preferably, the quick-release bushing includes a fixed bushing, a sliding bushing, and a telescopic airbag arranged coaxially. The axially opposite end faces of the fixed bushing and the sliding bushing are sealed and fixedly connected by the telescopic airbag. The inner wall of the shaft hole is provided with toothed guide grooves with tooth tips facing the telescopic airbag along its circumference. The outer wall of the sliding bushing is fixedly provided with guide keys that slide in cooperation with the guide grooves. The outer wall of the pin is provided with a circumferentially extending transmission groove. Three or more sets of active slide keys with axial lengths less than the axial length of the transmission groove are fixedly fixedly arranged equidistantly along its circumference in the transmission groove. Three or more sets of axially extending driven slide keys are fixedly fixedly arranged equidistantly along its circumference in the inner wall of the sliding bushing. The driven slide keys slide in cooperation with the transmission groove. An axial flow fan blade that generates axial airflow with rotation is fixedly mounted on the outer end face of the sliding bushing. The fixed bushing is coaxially fixedly connected to the snap-fit ​​plate.

[0012] Preferably, the circumferential length of the guide groove at the end away from the telescopic airbag is greater than its circumferential length at the end near the telescopic airbag. When the guide key rotates circumferentially along the guide groove, it drives the sliding bushing to generate periodic axial reciprocating motion. The initial circumferential position of each set of driven keys is set at a circumferentially symmetrical position between two adjacent sets of active keys. In the initial installation state, the guide key is located at the axial end of the guide groove away from the telescopic airbag and at a circumferentially symmetrical position of the guide groove. The telescopic airbag is in an uncompressed initial volume state, and the driven key and the active key are in the same axial position.

[0013] Preferably, when the axial fan blades rotate clockwise, the airflow generated is directed towards the fixed bushing. When the pin rotates circumferentially, the active slide key rotates synchronously and pushes the driven slide key circumferentially, causing the sliding bushing to rotate synchronously. When the sliding bushing rotates, it synchronously causes the end of the telescopic airbag connected to it to rotate circumferentially, causing the telescopic airbag to rotate circumferentially and store elastic potential energy. At the same time, the guide slide key rotates with the sliding bushing and slides circumferentially along the guide tooth groove. When the guide slide key gradually moves from the side axially away from the telescopic airbag to the side axially close to the telescopic airbag, it causes the sliding bushing and the driven slide key to synchronously move axially closer to the telescopic airbag, causing the circumferential pushing relationship between the driven slide key and the active slide key to be released. The telescopic airbag releases elastic potential energy to generate elastic reset, causing the sliding bushing to rotate circumferentially to reset, and synchronously causing the axial fan blades to rotate clockwise to deliver the airflow towards the fixed bushing.

[0014] Preferably, the axial length of the driven slide key is less than the axial length of the driving slide key; three or more sets of guide tooth grooves are equidistantly provided along the circumference of the shaft hole, and the tooth root positions of the three or more sets of guide tooth grooves are circumferentially interconnected; the guide tooth grooves, guide slide keys, driving slide keys, and driven slide keys are all machined with transition chamfers; the inner diameter of the driven slide key is less than the inner diameter of the sliding bushing; the outer diameter of the guide slide key is greater than the diameter of the sliding bushing; the inner diameter of the guide tooth groove is greater than the diameter of the shaft hole; the inner diameter of the transmission slide groove is less than the diameter of the pin; and a guide cone surface is machined on the side end face of the sliding bushing that connects with the axial fan blade to guide the airflow generated by the axial fan blade to the axial direction; a radial elastic telescopic structure is provided between the driven slide key and the guide slide key and the sliding bushing; and guide inclined surfaces are machined on the tooth tip position end face of the guide tooth groove and the side end face of the transmission slide groove near the telescopic airbag.

[0015] Preferably, the elastic telescopic structure includes a radial groove machined on the sliding bushing and springs respectively installed between the guide key and the driven key, and the guide ramp presses the driven key and the guide key into the radial groove.

[0016] Preferably, the snap fastener and the arc-shaped snap groove are connected by a thread.

[0017] Preferably, the total axial length of the quick-release bushing is greater than the axial length of the shaft hole.

[0018] Preferably, the support frame is fixedly equipped with two or more sets of support gears that support the movement of the chain along the direction of chain movement.

[0019] (III) Beneficial Effects Compared with the prior art, the present invention provides a detachable mobile box for automatic moisture retention production of mushrooms, which has the following beneficial effects: 1. This automatic moisture-retaining detachable mobile mushroom cultivation box, through the combined use of a quick-release bushing structure and a water replenishment platform structure, achieves rapid installation and disassembly of the cultivation box under load, compared to traditional technical structures. It eliminates the need to disassemble the chain drive structure or transfer the mushroom material inside the cultivation box, significantly improving the efficiency of disassembly, assembly, and maintenance. During water replenishment, the opposing convection water replenishment relationship formed by the cultivation box descending vertically along the drive gear and the nozzles spraying water upwards along the drive gear significantly enhances the interaction between the water flow and the bottom surface of the cultivation box. The improved contact speed allows water to penetrate and moisturize the cultivation substrate at the bottom of the incubator more quickly and thoroughly, greatly improving the efficiency and effectiveness of water replenishment under the same water supply pressure. It also ensures more uniform and sufficient contact between water and the bottom of the incubator, avoiding problems such as uneven water replenishment or untimely penetration. Furthermore, the water replenishment and moisturizing operation of the entire incubator can be completed with only a single water replenishment station, greatly simplifying the structural layout of the water replenishment system, reducing the manufacturing cost of the equipment and the difficulty of subsequent operation and maintenance, and completely avoiding the problem of the equipment being in a high humidity condition for a long time due to multiple spray stations throughout the entire process.

[0020] 2. This automatic moisture-retaining detachable mobile mushroom production box, through the combined use of an active gear structure and a water spray plate structure, achieves full synchronous coverage of the spray water trajectory and the rotation trajectory of the cultivation box compared to traditional technical structures. This eliminates spray dead zones during the rotation of the cultivation box, ensuring that the bottom surface of the cultivation box receives uniform spraying across the entire area without interruption, thus improving the uniformity and sufficiency of water replenishment. At the same time, the arc-shaped water spray plate, which is adapted to the rotation trajectory of the cultivation box, significantly shortens the fall path of unabsorbed water, weakens the splashing phenomenon caused by water droplets falling back, effectively reduces the problem of increased humidity in the surrounding environment caused by water splashing and overflow, and further avoids moisture corrosion of equipment components.

[0021] 3. This detachable mobile automatic moisture-retaining production box for mushrooms utilizes a quick-release bushing structure and a pin structure. Compared to traditional technologies, this application leverages the rotation of the pin relative to the bearing seat during chain movement, which drives the circumferential rotation and axial movement of the sliding bushing. This eliminates the need for additional drive components, allowing the telescopic airbag to complete elastic energy storage and automatic reset. It fully utilizes the equipment's own operating power. Furthermore, the radial deformation generated by the telescopic airbag during torsional deformation and reset creates cyclical positive and negative pressure within the shaft hole, ensuring continuous gas flow and effectively preventing moisture accumulation in the fitting gaps. Simultaneously, during the reset process of the sliding bushing... The directional axial airflow generated by the axial flow fan blades can continuously purge the mating gap between the quick-connect bushing, pin, and shaft hole, expelling condensed water vapor and water vapor splashed in by the spray, further improving the drying and protection effect of the mating gap and extending the service life of the quick-connect connection structure. In addition, the guide cone surface on the end face of the sliding bushing can guide the airflow to the annular mating gap between the sliding bushing and the shaft hole, provided that the outer diameter of the axial flow fan blade does not exceed the sliding bushing and assembly feasibility is ensured. This improves the uniformity and effectiveness of the airflow purging and enhances the water vapor discharge effect. At the same time, the elastic structure of the telescopic airbag can effectively absorb the vibration and steering impact during the chain drive process, reducing the wear of the mating structure.

[0024] The technical solutions of the embodiments of the present invention will be clearly and completely described below with reference to the accompanying drawings. Obviously, the described embodiments are only some embodiments of the present invention, and not all embodiments. Based on the embodiments of the present invention, all other embodiments obtained by those skilled in the art without creative effort are within the scope of protection of the present invention.

[0025] Example 1 Please see Figures 1-9A detachable mobile automatic moisture-retaining production box for mushrooms includes a support frame 1. A drive gear 11 and two or more driven gears 12 are rotatably mounted on both sides of the support frame 1. A chain 13 meshes between the driven gears 12 and the drive gear 11. Two or more pins 5 are equidistantly mounted on the chain 13 along its length. Both the drive gear 11 and the driven gears 12 adopt a standard transmission tooth profile structure adapted to the chain 13. Both are coaxially rotatably mounted on the support frame 1 via a rotating support member. The rotating support component on the side wall can effectively limit the radial movement and axial offset of the gear, ensuring the smoothness of the gear and chain 13 meshing transmission. The chain 13 adopts a closed-loop flexible transmission structure to adapt to the multi-layer cyclic running trajectory. The chain links 131 are connected by movable hinges to smoothly complete the steering and meshing actions. The pin 5 adopts a rigid cylindrical structure, and its two ends are rigidly fixed to the chain links 131 of the chain 13. The equidistantly arranged pins 5 can make the incubator 2 evenly distributed on the chain 13. Furthermore, an incubator 2 is also installed on the support frame 1. Bearing seats 3 are fixedly installed on both sides of the incubator 2. The bearing seats 3 have shaft holes 31 machined inside to accommodate the pin 5. A vertical clearance opening 32 is provided at the bottom of the shaft hole 31 along its radial direction, penetrating the bearing seat 3. The pin 5 is vertically aligned and inserted into the shaft hole 31 through the clearance opening 32. The incubator 2 adopts a rigid frame structure to ensure the load-bearing stability of the mushroom cultivation. The bearing seats 3 adopt a block-shaped rigid solid structure and are fixedly connected to the outer wall of the side plate 21 of the incubator 2 in a perpendicular state. The components are connected by a stable rigid connection to avoid loosening or displacement during operation. The shaft hole 31 adopts a circular coaxial through hole structure to adapt to the outer dimensions of the pin 5 to form a rotational fit. The clearance opening 32 adopts a through groove structure that runs vertically through the radial direction of the bearing seat 3, and the two sides are machined with rounded corners. Its opening size is adapted to the outer dimensions of the pin 5. The vertical clearance opening 32 allows the pin 5 to be quickly aligned and installed into the shaft hole 31 in the vertical direction without disassembling the chain 13, which greatly simplifies the assembly and positioning process of the incubator 2. A quick-release bushing 4 is assembled between the pin 5 and the shaft hole 31. The quick-release bushing 4 is rotatably connected to the pin 5. A snap-fit ​​plate 41 is provided between the quick-release bushing 4 and the incubator 2 to fix the quick-release bushing 4 in the shaft hole 31. The quick-release bushing 4 adopts a coaxial hollow sleeve structure. Its outer wall forms a clearance fit with the inner wall of the shaft hole 31, and its inner wall forms a clearance fit with the outer wall of the pin 5. This can effectively isolate the direct contact between the pin 5 and the shaft hole 31 and ensure the smoothness of the rotational fit. The quick-release bushing 4 is made of wear-resistant rigid material to improve the service life of the fit structure. The snap-fit ​​plate 41 adopts a plate-shaped rigid structure and is coaxially fixedly connected to the end of the quick-release bushing 4. The outer dimensions of the snap-fit ​​plate 41 are larger than the diameter of the shaft hole 31, which can form a reliable axial limit for the quick-release bushing 4, and firmly limit the quick-release bushing 4 inside the shaft hole 31 to prevent the quick-release bushing 4 from axial movement and circumferential loosening.Furthermore, a water replenishment platform 6 is installed below the drive gear 11, and a nozzle 63 is fixedly installed inside the water replenishment platform 6 to replenish water to the bottom surface of the incubator 2 that has moved to the drive gear 11. The water replenishment platform 6 adopts a closed rigid cavity structure to achieve centralized storage and directional delivery of water. The water replenishment platform 6 and the support frame 1 are rigidly fixedly connected to ensure that the position is constant and does not shift. The nozzle 63 adopts a directional direct spray structure. The nozzle 63 and the internal cavity of the water replenishment platform 6 are sealed and connected to ensure stable water supply. The layout position and spray direction of the nozzle 63 are adapted to the movement trajectory of the incubator 2 through the drive gear 11, so that it can accurately spray water to the bottom surface of the incubator 2 that has moved to the corresponding area. The closed cavity structure can effectively reduce water leakage and waste, and reduce the humidity fluctuation of the surrounding environment of the equipment.

[0026] Please see Figures 1-9 The chain 13 engages with the drive gear 11 along the vertical tangential direction and disengages from the drive gear 11 along the horizontal tangential direction. The water supply platform 6 is positioned below the drive gear 11 along the vertical tangential direction, and the spray direction of the nozzle 63 is parallel to and upwards along the vertical tangential direction of the drive gear 11. This engagement and arrangement of the water supply platform 6 are designed with a transmission trajectory orientation, providing stable motion guidance constraints for the transmission engagement of the chain 13 and the drive gear 11, effectively preventing deviation and erratic movement during transmission. The directional arrangement of the water supply platform 6 and the nozzle 63 allows the spray water to accurately act on the working area along the transmission tangential direction, while avoiding abnormal scouring of the transmission engagement parts by the water flow. Both ends of the water replenishment platform 6 are fixedly connected to the support frame 1. The water replenishment platform 6 also has a fixedly sealed water inlet pipe 61 and a water outlet pipe 62 at both ends. A water pump is connected to the outside of the water inlet pipe 61. The water inlet pipe 61 is horizontally installed through the water replenishment platform 6, and two or more sets of nozzles 63 are equidistantly arranged along the length of the water inlet pipe 61. The spray direction of the nozzles 63 is perpendicular to the bottom surface of the cultivation box 2. The fixed connection at the ends of the water replenishment platform 6 improves the overall structural integrity. The sealed pipe connection effectively prevents leakage during water delivery. The horizontally installed water inlet pipe 61 ensures stable and uniform water distribution. The equidistant arrangement of the nozzles 63 ensures comprehensive and uniform coverage of the spray area. The spray direction perpendicular to the bottom surface of the cultivation box 2 ensures that the water flows evenly onto the mushroom cultivation support area.

[0027] Please see Figures 1-9The incubator 2 includes side plates 21 arranged opposite to each other on both sides and a bottom connecting frame 22 fixedly connected between the two side plates 21. A mesh cloth 23 for supporting mushrooms is fixedly mounted on the connecting frame 22. The mesh cloth 23 also contains the mushroom cultivation soil. The mesh cloth 23 is made of non-woven fabric. The frame-type combined connection structure of the incubator 2 can ensure the overall load-bearing strength and structural stability. The tensioned support structure of the mesh cloth 23 can provide uniform and reliable support for the mushroom soil, preventing the mushroom soil from scattering and shifting. The frame-type connection form facilitates subsequent disassembly and maintenance operations. The support structure of the mesh cloth 23 can adapt to the ventilation environment requirements required for mushroom growth. While providing a stable load-bearing space for mushroom cultivation, it ensures the environmental permeability and structural practicality of the cultivation area, so that the bottom can fully absorb the water sprayed from the nozzle 63 when passing the water replenishment platform 6. The bearing housing 3 is fixedly connected to the outside of the side plate 21. The quick-release bushing 4 is axially inserted into the shaft hole 31 from the inside of the incubator 2, and the snap-fit ​​plate 41 is set at the end of the quick-release bushing 4 near the inside of the side plate 21. The rigid fixing form of the outer side of the bearing housing 3 can ensure the positioning accuracy and running stability of the rotating mating parts. The axial insertion form of the inner side of the quick-release bushing 4 can simplify the assembly process and avoid external assembly interference. The inner arrangement of the snap-fit ​​plate 41 can realize the built-in protection of the limiting structure and reduce the influence of the external environment on the limiting component. A snap-fit ​​buckle 42 is fixedly provided on the snap-fit ​​plate 41. An arc-shaped snap-fit ​​groove 221 with the shaft hole 31 as the center is opened on the side plate 21. The snap-fit ​​buckle 42 can rotate with the snap-fit ​​plate 41 around the axis of the shaft hole 31 and engage in the arc-shaped snap-fit ​​groove 221 to restrict the axial movement of the quick-release bushing 4. The snap-fit ​​buckle 42 and the arc-shaped snap-fit ​​groove 221 adopt a coaxial rotational snap-fit ​​elastic locking structure, which can realize the quick positioning of the quick-install bushing 4 and axial anti-dislodgement constraint. The center positioning design of the arc-shaped snap-fit ​​groove 221 can ensure the coaxial smoothness of the snap-fit ​​movement. The rotational snap-fit ​​engagement form can achieve reliable locking without additional fastening components, which simplifies the assembly process while ensuring the limiting effect.

[0028] Please see Figures 1-9The chain 13 consists of two or more sets of chain links 131, and the pin 5 is fixedly installed at the connection between each set of chain links 131. The width of the clearance opening 32 is greater than the diameter of the pin 5 and smaller than the diameter of the quick-release bushing 4. The chain links 131 are stably hinged together by the pin 5. As the core connecting component for the transmission of chain links 131, the pin 5 can ensure the flexibility and structural strength of the relative movement of each chain link 131 during the transmission of the chain 13. The size limitation of the clearance opening 32 can provide space for the pin 5 to pass through, and at the same time form a reliable axial limit for the quick-release bushing 4. Driven gears 12 are rotatably mounted in two or more layers along the height of the support frame 1. Driven gears 11 on both sides are located at the bottom of the support frame 1. Chains 13 move horizontally upwards, passing each driven gear 12. When chain 13 reaches the top driven gear 12, it moves vertically downwards to the drive gear 11. Driven gears 14 are coaxially fixedly connected to the drive gears 11, and drive gears 14 are connected to a drive motor. The drive motor is a three-phase asynchronous geared motor or a stepper geared motor with an integrated reducer. The driven gears 12 are all coaxially mounted on the side wall mounting position of the support frame 1 via seated bearings. The rotation centers of each layer of driven gears 12 are all in the same vertical plane to ensure the regularity of the rotation trajectory of the chain 13. The design of the drive gears 11 being centrally arranged at the bottom of the support frame 1 facilitates the centralized installation and subsequent maintenance of the drive components, and can also be adapted to the installation layout of the water replenishment platform 6, enabling precise water replenishment during the rotation of the incubator 2. The drive gear 14 and the drive gear 11 are coaxially fixed by a flat key connection, which ensures the synchronization and efficiency of power transmission. The drive motor is connected to the drive gear 14 through a reduction transmission mechanism, which can provide stable and torque-matched power output for the cyclic movement of the chain 13. The serpentine cyclic trajectory formed by the multiple layers of driven gears 12 can make full use of the vertical space of the support frame 1, increase the mushroom cultivation capacity per unit area, and improve space utilization. The snap-fit ​​buckle 42 and the arc-shaped snap-fit ​​groove 221 are connected by threads. The snap-fit ​​buckle 42 includes a smooth rod section vertically fixedly connected to the snap-fit ​​plate 41 and an externally threaded section integrally machined at the end of the smooth rod section. The arc-shaped snap-fit ​​groove 221 is an arc-shaped through groove provided through the side plate 21. The width of the arc-shaped through groove is greater than the outer diameter of the externally threaded section and smaller than the outer diameter of the smooth rod section. After the externally threaded section passes through the arc-shaped snap-fit ​​groove 221, a locking nut is fitted. The outer diameter of the locking nut is greater than the width of the arc-shaped snap-fit ​​groove 221. By tightening the locking nut, the locking nut and the shoulder of the smooth rod section can be engaged to clamp the side plate 21, realizing a stable connection between the snap-fit ​​buckle 42 and the arc-shaped snap-fit ​​groove 221. This threaded connection structure can realize the quick locking and disassembly of the quick-release bushing 4, and can also effectively prevent the connection structure from loosening during equipment vibration through the self-locking performance of the thread pair. The total axial length of the quick-release bushing 4 is greater than the axial length of the shaft hole 31.This dimensional design allows the quick-release bushing 4 to extend beyond the axial end face of the shaft hole 31 after assembly. This avoids the problem of the quick-release bushing 4 becoming completely stuck inside the shaft hole 31 and unable to be removed, ensuring the operability of disassembly operations. It also provides sufficient axial operating space for the installation and fixation of the snap-fit ​​plate 41. At the same time, it effectively increases the mating length between the quick-release bushing 4, the pin 5, and the shaft hole 31, improving the coaxiality and stability of the rotational fit, reducing uneven wear on the mating surfaces, extending the service life of the quick-release bushing 4, and effectively shielding the openings at both ends of the shaft hole 31, reducing the entry of sprayed water vapor and dust into the mating gap. Two or more sets of support gears are fixedly installed on the support frame 1 to support the movement of the chain 13 along the direction of movement of the chain 13. The support gears are rotatably mounted on the side wall of the support frame 1 via bearings. Each support gear is equidistantly arranged along the horizontal movement trajectory of the chain 13, and the tooth profile of the support gear is adapted to the pitch of the chain 13, so that it can form a stable meshing support with the chain 13. It can effectively support the long horizontal section of the chain 13, greatly reduce the sag of the chain 13 caused by its own weight and the vibration during operation, and prevent the chain 13 from failing to mesh with the driven gear 12 and the driving gear 11 due to excessive sag.

[0029] Please see Figures 1-9When installing the incubator 2, first, the drive motor is powered off and locked, keeping the pins 5 on the chain 13 at the installation position horizontal and stationary. The set of pins 5 symmetrically distributed on both sides of the chain 13 and located at the bottom of the support frame 1 is selected as the installation reference. Then, the incubator 2 is smoothly lifted to the appropriate height for the corresponding installation position on the support frame 1. The spatial position of the incubator 2 is adjusted so that the center of the shaft hole 31 of the bearing seat 3 fixed to the outer wall of the side plates 21 on both sides of the incubator 2 is in the same vertical plane as the center of the corresponding pin 5 on the chain 13. The circumference of the bearing seat 3 is adjusted synchronously. Oriented so that the clearance opening 32 at the bottom of the shaft hole 31 is vertically downward and directly aligned with the pin 5, the incubator 2 is then vertically lowered so that the pin 5 is fully engaged in the shaft hole 31 of the bearing seat 3 through the clearance opening 32. After being lowered into place, the incubator 2 achieves initial support and positioning through the cooperation between the bearing seats 3 on both sides and the pin 5. Then, the side plate 21 on the corresponding side of the incubator 2 is lifted to ensure that the pin 5 and the shaft hole 31 of the bearing seat 3 are in a completely coaxial fit. Then, from the inside of the side plate 21 of the incubator 2, the quick-release bushing 4 is coaxially inserted into the annular fit gap between the pin 5 and the shaft hole 31, thereby fixing the pin 5 and the shaft hole 31. The quick-release bushing 4 and the pin 5 are coaxially fitted. After insertion, a rotational fit is formed between the quick-release bushing 4 and the pin 5. Then, the snap-fit ​​plate 41 at the end of the quick-release bushing 4 is rotated around the central axis of the shaft hole 31, so that the snap-fit ​​buckle 42 fixed on the snap-fit ​​plate 41 is engaged into the arc-shaped snap-fit ​​groove 221 on the side plate 21, thereby forming an axial limit for the quick-release bushing 4. Then, the snap-fit ​​buckle 42 is rotated, so that the snap-fit ​​buckle 42 is circumferentially fixed with the arc-shaped snap-fit ​​groove 221 through the threaded connection. At this time, the outer wall of the quick-release bushing 4 completely seals the relief opening 32 at the bottom of the shaft hole 31, preventing the pin 5 from disengaging from the relief opening 32, completing the single-sided quick-release bushing. The locking and fixing of the bushing 4 is completed on the other side of the culture box 2 using the same operation procedure. This allows the culture box 2 to be securely mounted on the chains 13 on both sides of the support frame 1, completing the quick installation of the culture box 2. When it is necessary to disassemble the culture box 2, simply reverse the above installation operation procedure to complete the quick disassembly of the culture box 2. All the above installation and disassembly operations can be completed while the culture box 2 is loaded with mushroom sticks and mushrooms. During the operation, there is no need to disassemble the chain 13 transmission structure or transfer the mushroom material inside the culture box 2.

[0030] Please see Figures 1-9During operation, the device drives the drive gear 14 via a drive motor, which in turn drives the drive gear 11 to rotate. This, in turn, drives the chain 13, which meshes with the drive gear 11 and each driven gear 12, to continuously rotate along a preset cyclic trajectory. This allows the incubator 2, mounted on the pin shaft 5, to circulate with the chain 13. During the cyclic rotation of the incubator 2 driven by the chain 13, when the incubator 2 moves to the drive gear 11, the water replenishment platform 6 below the drive gear 11 replenishes water to the bottom surface of the incubator 2 via nozzles 63 on the water inlet pipe 61. As the incubator 2 descends along the vertical tangential direction of the drive gear 11, the water spray direction of the nozzles 63 is also upward, facing the vertical tangential direction of the drive gear 11. Therefore, the two directions of movement form a countercurrent flow, resulting in faster and more thorough contact between the water flow and the bottom surface of the incubator 2. Under the same water supply pressure, this significantly improves water penetration and wetting efficiency, thereby effectively improving the overall efficiency of the water replenishment operation. Furthermore, during the spraying process from the nozzle 63 directly towards the bottom of the incubator 2, the water generated by the spray can pass through the uniform pores of the mesh 23 on the bottom connecting frame 22 of the incubator 2 to permeate the soil from the bottom below the mushrooms upwards. This ensures that the water is evenly and slowly stored in the internal pores of the soil, avoiding the problems of rapid water loss and uneven moisture distribution in the soil caused by direct water washing over the mushroom fruiting bodies and surface substrate compaction, as well as the traditional top spraying method. This significantly extends the water retention time of the soil, allowing it to maintain its moisture level in the incubator 2. Throughout the complete cycle of a closed-loop circulation, the chain 13 can maintain a stable high moisture content that meets the normal growth requirements of mushrooms. Therefore, there is no need to deploy multiple sets of water spray structures along the entire circulation path of the support frame 1. A single water spray platform 6 can complete the precise water replenishment and humidification work for all the incubators 2 that circulate with the chain 13. This greatly simplifies the water replenishment system structure of the equipment, reduces the equipment manufacturing cost and the difficulty of later operation and maintenance, and completely avoids the industry pain points of multiple sprays throughout the space causing the equipment to be in a high humidity condition for a long time and the transmission structure and electrical components to be prone to corrosion and failure.

[0031] Example 2 Please see Figure 10An arc-shaped spray plate 64 is also fixedly installed on the water replenishment platform 6. The spray plate 64 is positioned above the water inlet pipe 61. The center of the arc of the spray plate 64 is the center of the drive gear 11, and the radius of the arc is larger than the radius of rotation of the incubator 2 along the drive gear 11. The spray plate 64 is integrally stamped from rigid and corrosion-resistant stainless steel. Its two ends are rigidly fixed to the side wall of the water replenishment platform 6 by bolts. The inner arc surface of the spray plate 64 and the outer trajectory surface of the incubator 2 rotating around the drive gear 11 form a fully parallel and equidistant fit relationship. This concentric arc structure is used. The reason for this design is to ensure that the vertical distance between the spray plate 64 and the bottom surface of the incubator 2 remains constant throughout the entire rotation of the incubator 2, avoiding uneven water pressure and spray range deviation caused by distance changes. At the same time, the arc-shaped structure can completely wrap around the rotation path of the incubator 2 around the drive gear 11, providing a suitable mounting base for the placement of the nozzles 63, ensuring full coverage of the spraying operation, and also providing protection for the water droplets falling from the incubator 2, preventing water droplets from splashing directly onto the transmission structure and electrical components of the equipment, reducing the risk of moisture and corrosion of the equipment. Two or more sets of nozzles 63 are equidistantly arranged along the axial direction and the arc axis of the spray plate 64. The nozzles 63 are fixedly installed in the preset mounting holes on the spray plate 64 by means of threaded sealing connection. The water inlet end of each nozzle 63 is sealed and connected to the internal cavity of the water inlet pipe 61 through a flexible water supply branch pipe. The spray nozzle of the nozzle 63 is set towards the center of the rotation trajectory of the incubator 2, and the spray axis of all nozzles 63 is perpendicular to the bottom surface of the incubator 2 when it passes the corresponding position. The reason for adopting this dual-axial equidistant array arrangement structure is that it can form a uniform spray coverage of the entire bottom surface of the incubator 2 without dead angles and without interruption throughout the entire stroke of the incubator 2 around the drive gear 11, eliminating the spray blind spots during the movement of the incubator 2, ensuring that every area of ​​the bottom surface of the incubator 2 can be uniformly sprayed with water, and avoiding the problem of insufficient or excessive water replenishment in some areas. The spray plate 64 is machined with drain holes 641 that allow water accumulated on its surface to flow back into the water replenishment platform 6. Two or more sets of drain holes 641 are machined on the spray plate 64. The drain holes 641 adopt a through-hole structure that is equidistantly machined along the arc axis of the spray plate 64. The lower end of the drain hole 641 is sealed and connected to the internal water storage cavity of the water replenishment platform 6 through a guide pipe. The inner wall of the drain hole 641 is machined with a smooth flow-guiding chamfer, and the layout of the drain holes 641 corresponds to the water collection area on the spray plate 64. The reason for adopting this structural design is that the drain holes 641 can quickly guide the water that falls back onto the surface of the spray plate 64 and is not absorbed by the bacterial soil back into the water replenishment platform 6, realizing the recycling of water resources, reducing the water consumption of the equipment, and avoiding the problem of water accumulating on the surface of the spray plate 64 for a long time, breeding microorganisms, and clogging the nozzles 63.

[0032] Please see Figure 10In this embodiment, the spray plate 64 on the water replenishment platform 6 adopts an arc-shaped structure concentrically arranged with the drive gear 11. The center of the arc of the spray plate 64 is completely coincident with the rotation axis of the drive gear 11, and the radius of the arc is larger than the rotation radius of the incubator 2 along the drive gear 11. This makes the arc contour of the spray plate 64 and the rotation trajectory of the incubator 2 around the drive gear 11 parallel and equidistant throughout the entire process. The spray trajectories of the nozzles 63, which are equidistantly arrayed along the arc axis of the spray plate 64, are spatially... The rotational trajectory of the incubator 2 is completely coincident with that of the incubator 2. When the incubator 2 rotates continuously around the drive gear 11 with the chain 13, its bottom surface is always within the effective spray coverage range of the corresponding nozzle 63 at every instant of the entire rotation stroke. This achieves full synchronous coverage of the spray water trajectory and the movement trajectory of the incubator 2, eliminating the spray dead angle and uneven spraying problems during the rotation of the incubator 2, and enabling the entire bottom surface of the incubator 2 to be sprayed evenly and continuously throughout the entire area. Meanwhile, when the water at the bottom of the incubator 2 and the mesh 23 that has not been absorbed by the fungal soil falls back under the influence of gravity, the water droplets can always fall on the surface of the spray plate 64 with the minimum vertical distance between them and the surface of the spray plate 64, which greatly shortens the free fall path of the water droplets and reduces the kinetic energy accumulated during the fall. This weakens the splashing phenomenon caused by the water droplets hitting the plate surface. The water that falls back to the surface of the spray plate 64 can quickly flow back to the water replenishment platform 6 through the drain holes 641 processed on the spray plate 64 to achieve recycling. This further reduces the problem of increased humidity in the surrounding environment caused by water splashing and overflow. It achieves precise water replenishment and moisturization of the mushrooms in the incubator 2 and completely avoids the pain points of high humidity environment around the equipment, corrosion failure of transmission structure and electrical components caused by traditional full-space water mist spraying.

[0033] Example 3 Please see Figures 11-15The quick-release bushing 4 includes a fixed bushing 43, a sliding bushing 45, and a telescopic airbag 44, all coaxially arranged. The axially opposite end faces of the fixed bushing 43 and the sliding bushing 45 are sealed and fixedly connected by the telescopic airbag 44. The telescopic airbag 44 is integrally molded from a flexible rubber material that is resistant to aging and corrosion. Its two ends are respectively sealed and fixedly connected to the axially opposite end faces of the fixed bushing 43 and the sliding bushing 45 by hot vulcanization bonding. The inner cavity of the telescopic airbag 44 is coaxially connected to the central through hole of the fixed bushing 43 and the sliding bushing 45, and the axial length of the telescopic airbag 44 in its natural state is adapted to the pre-tensioning between the fixed bushing 43 and the sliding bushing 45. The reason for using this sealed and fixed connection structure with the specified spacing is that the telescopic airbag 44 can provide a flexible axial and circumferential transmission connection between the fixed bushing 43 and the sliding bushing 45, ensuring that the sliding bushing 45 can generate stable axial reciprocating motion and circumferential rotational reset action relative to the fixed bushing 43. It can also form a complete seal and isolation between the connection part between the fixed bushing 43 and the sliding bushing 45, effectively preventing external moisture and dust from entering the internal fitting gap of the quick-release bushing 4, avoiding the problems of rust and jamming of the internal fitting components. At the same time, the flexible structure of the telescopic airbag 44 can effectively absorb the vibration and impact generated during the transmission of the chain 13, reduce the wear of the fitting structure, and improve the stability and service life of the quick-release bushing 4. The inner wall of the shaft hole 31 is provided with a toothed guide groove 33 along its circumference, with the tooth tip facing the telescopic airbag 44. A guide key 451 is fixedly provided on the outer wall of the sliding bushing 45, which slides with the guide groove 33. The guide groove 33 adopts a continuous sawtooth annular groove structure, and its groove depth gradually narrows along the axial direction towards the telescopic airbag 44. The inner wall of the groove is machined with a smooth wear-resistant coating. The guide key 451 adopts a block-shaped rigid structure adapted to the tooth shape of the guide groove 33. Its root is integrally formed and fixedly connected to the outer wall of the sliding bushing 45. The outer end face of the guide key 451 is machined with an arc-shaped transition surface that fits with the inner wall of the guide groove 33. The reason for adopting this structural design is that the tooth tip faces the telescopic airbag 44. The toothed groove 33 provides precise guiding constraints for the circumferential rotation of the guide key 451, enabling the guide key 451 to synchronously move axially toward the telescopic airbag 44 during the circumferential rotation of the sliding sleeve 45. This eliminates the need for additional drive components, fully utilizing the equipment's own operating power. Furthermore, the sliding fit between the guide key 451 and the guide toothed groove 33 provides stable limits for the circumferential rotation and axial movement of the sliding sleeve 45. A circumferentially extending transmission groove 51 is provided on the outer wall of the pin 5. Within the transmission groove 51, three or more sets of active slide keys 52, each with an axial length less than the axial length of the transmission groove 51, are fixedly and equidistantly along its circumference.Three or more axially extending driven slide keys 452 are fixedly and equidistantly arranged on the inner wall of the sliding bushing 45 along its circumference. The driven slide keys 452 are axially slidingly engaged with the transmission groove 51. The transmission groove 51 is an annular groove structure extending circumferentially along the outer wall of the pin 5. Both the bottom and the wall of the groove are machined with a wear-resistant hardened layer. The driving slide key 52 adopts a rectangular block rigid structure. Its root is embedded and fixed to the inner wall of the bottom of the transmission groove 51 by an interference fit. Both axial ends of the driving slide key 52 and the axial groove wall of the transmission groove 51 are reserved with clearance space for the axial sliding of the driven slide key 452. The driven slide key 452 adopts the same sliding fit as the driving slide key 51. 2. A rectangular, rigid structure with a matching shape, whose root is integrally formed and fixedly connected to the inner wall of the sliding bushing 45. The radial protrusion height of the driven slide key 452 is matched with the groove depth of the transmission slide groove 51. An axial flow fan blade 46 that generates axial airflow with its rotation is fixedly mounted on the outer end face of the sliding bushing 45. The axial flow fan blade 46 is integrally injection molded from lightweight and corrosion-resistant engineering plastic material. Its hub center is coaxially mounted to the outer end face of the sliding bushing 45 by interference fit. The blades of the axial flow fan blade 46 adopt a forward-inclined arc structure. The rotation direction of the blades is preset so that the airflow generated when the axial flow fan blade 46 rotates with the sliding bushing 45 in the forward direction is... The airflow is directed towards the fixed bushing 43, and the maximum outer diameter of the axial fan blade 46 does not exceed the outer diameter of the sliding bushing 45. The fixed bushing 43 is coaxially fixedly connected to the snap-fit ​​plate 41. The end of the fixed bushing 43 near the inner side of the side plate 21 of the incubator 2 is rigidly fixedly connected to the snap-fit ​​plate 41 in an integral molding manner. The central axis of the fixed bushing 43 is completely coincident with the central axis of the snap-fit ​​plate 41. The plate surface of the snap-fit ​​plate 41 is perpendicular to the axial end face of the fixed bushing 43. The connection between the outer wall of the fixed bushing 43 and the snap-fit ​​plate 41 is processed with a reinforcing rib structure. The reason for adopting this coaxial fixed connection structure is that the integral molding fixed connection method can... To ensure the connection strength and coaxiality between the fixed bushing 43 and the snap-fit ​​plate 41, and to prevent eccentric rotation of the quick-release bushing 4 and loosening or falling off of the snap-fit ​​plate 41 during operation, the vertically positioned snap-fit ​​plate 41 forms a stable surface contact with the inner wall of the side plate 21 of the incubator 2, providing reliable axial positioning for the quick-release bushing 4 and preventing axial movement of the quick-release bushing 4 within the shaft hole 31. This ensures the rotational fit accuracy between the quick-release bushing 4, the pin 5, and the shaft hole 31. The reinforcing rib structure further enhances the structural strength of the connection, preventing deformation or breakage of the snap-fit ​​plate 41 during rotational locking and equipment vibration.

[0034] Please see Figures 11-15The circumferential length of the guide groove 33 at the end away from the telescopic airbag 44 is greater than that at the end closer to the telescopic airbag 44. When the guide key 451 rotates circumferentially along the guide groove 33, it drives the sliding sleeve 45 to produce periodic axial reciprocating motion. The initial circumferential position of each set of driven keys 452 is set at a circumferentially symmetrical position between two adjacent sets of active keys 52. The guide groove 33 adopts an irregularly shaped groove structure with a gradually changing circumferential width. The circumferential width at the end away from the telescopic airbag 44 is larger, which allows the guide key 451 to have sufficient circumferential mobility at this position. The circumferential width of the guide key 451 gradually narrows near the end of the telescopic airbag 44, which forces the guide key 451 to generate axial displacement when it rotates to this position. This, in turn, drives the sliding bushing 45 to complete a periodic axial reciprocating motion, achieving a composite axial and circumferential motion without additional driving components. The initial circumferential position of the driven key 452 is set symmetrically between the adjacent driving key 52, ensuring that the driving key 52 can stably push the driven key 452 regardless of whether the pin 5 rotates forward or backward, thus guaranteeing the reliability and bidirectional adaptability of the circumferential transmission. In the initial installation state, the guide key 451 is located at the axial end of the guide tooth groove 33 away from the telescopic airbag 44 and is symmetrically positioned at the circumferential center of the guide tooth groove 33. The telescopic airbag 44 is in its initial uncompressed volume state, and the driven key 452 and the driving key 52 are in the same axial position. This initial installation state is the baseline state after the equipment is assembled and reset. The guide key 451 is located at the axial end of the guide tooth groove 33 away from the telescopic airbag 44 and is centrally positioned, which can ensure the stability of the initial position of the sliding bushing 45. The telescopic airbag 44 maintains a natural and uncompressed initial state, which can provide sufficient deformation space for subsequent elastic energy storage and reset actions. The driven key 452 and the active key 52 are located in the same axial position, which can ensure that when the pin 5 rotates, the active key 52 can immediately form a push-fit with the driven key 452, avoiding the problem of transmission lag or fit failure.

[0035] Please see Figures 11-15When the axial fan blade 46 rotates clockwise, the airflow generated is directed toward the fixed bushing 43. When the pin 5 rotates circumferentially, the active slide key 52 rotates synchronously and pushes the driven slide key 452 circumferentially, causing the sliding bushing 45 to rotate synchronously. When the sliding bushing 45 rotates, it synchronously drives the end of the telescopic airbag 44 connected to it to rotate circumferentially, causing the telescopic airbag 44 to generate circumferential rotational stretching and store elastic potential energy. At the same time, the guide slide key 451 rotates with the sliding bushing 45 and slides circumferentially along the guide tooth groove 33. When the guide slide key 451 gradually moves from the side axially away from the telescopic airbag 44 to the side axially close to the telescopic airbag 44, it drives the sliding bushing 45 and the driven slide key 452 to synchronously move axially close to the telescopic airbag 44, so that the circumferential pushing relationship between the driven slide key 452 and the active slide key 52 is released. The telescopic airbag 44 releases elastic potential energy to generate elastic reset, driving the sliding bushing 45 to rotate circumferentially to reset, and synchronously driving the axial fan blade 46 to rotate clockwise to deliver the airflow toward the fixed bushing 43.

[0036] Please see Figures 11-15The axial length of the driven slide key 452 is less than that of the driving slide key 52. ​​The guide grooves 33 are provided with three or more sets of guide grooves 33 at equal intervals along the circumference of the shaft hole 31, and the tooth roots of the three or more sets of guide grooves 33 are interconnected in the circumference. The axial length of the driven slide key 452 is shorter, so it can smoothly disengage from the pushing engagement of the driving slide key 52 when the sliding bushing 45 drives the driven slide key 452 to move axially, realizing automatic disengagement of circumferential transmission. The multiple sets of guide grooves 33 arranged at equal intervals can make the sliding bushing 45 be evenly stressed, avoiding uneven wear and jamming caused by unilateral stress. The tooth roots of the guide grooves 33 are interconnected, which can ensure the smoothness of the guide slide key 451 when rotating in the circumference and prevent local jamming from affecting the movement of the sliding bushing 45. The guide groove 33, guide slide key 451, active slide key 52 and driven slide key 452 are all machined with transition chamfers. The transition chamfers machined in each mating part are smooth arc chamfers, which can effectively eliminate the sharp edges of the mating edges, reduce the sliding friction resistance between guide slide key 451 and guide groove 33, active slide key 52 and driven slide key 452, avoid scraping and jamming during movement, and improve the guidance of each component during assembly. The inner diameter of the driven slide key 452 is smaller than the inner diameter of the sliding sleeve 45, the outer diameter of the guide slide key 451 is larger than the diameter of the sliding sleeve 45, the inner diameter of the guide groove 33 is larger than the diameter of the shaft hole 31, and the inner diameter of the transmission groove 51 is smaller than the diameter of the pin 5. This dimensional fit ensures a precise clearance fit and sliding guidance between the components. The smaller inner diameter of the driven slide key 452 allows it to form a stable axial sliding fit with the transmission groove 51 of the pin 5. The larger outer diameter of the guide slide key 451 allows it to be securely embedded in the guide groove 33 for reliable guidance. The larger inner diameter of the guide groove 33 provides ample space for the movement of the guide slide key 451. The smaller inner diameter of the transmission groove 51 limits the installation position of the driven slide key 52, ensuring the motion accuracy and stability of each mating structure. Furthermore, a guide cone surface is machined on the end face of the sliding bushing 45 that connects with the axial fan blade 46 to guide the airflow generated by the axial fan blade 46 to the axial direction. The guide cone surface is an outwardly expanding conical curved surface coaxially opened on the end face of the sliding bushing 45. This conical curved surface is symmetrically arranged with the central axis of the sliding bushing 45 as a reference. The inclination angle of the cone surface is preset to adapt to the airflow guidance requirements. With this structural design, the central concentrated airflow generated by the axial fan blade 46 can be evenly diffused outward along the cone surface and guided to the annular fitting gap between the sliding bushing 45 and the shaft hole 31, so that the airflow can completely cover the entire circumferential area of ​​the fitting gap, improve the uniformity and coverage of the airflow, and avoid local disturbances caused by concentrated airflow impacting a single part. Radial elastic telescopic structures are provided between the driven slide key 452 and the guide slide key 451 and the sliding bushing 45. Furthermore, guide inclined surfaces 9 are machined on the end face of the tooth tip of the guide tooth groove 33 and the end face of the transmission slide groove 51 near the telescopic airbag 44.Both the driven slide key 452 and the guide slide key 451 are movably assembled to the corresponding positions of the sliding bushing 45 through a radial elastic telescopic structure. The tip face of the guide tooth groove 33 and the end face of the transmission slide groove 51 near the telescopic airbag 44 are provided with smooth transition guide slopes 9. This structural design can use the extrusion force of the guide slopes 9 to radially press the driven slide key 452 and the guide slide key 451 into the interior of the sliding bushing 45 during the axial insertion and removal of the quick-installation bushing 4, so that the inner and outer surfaces of the sliding bushing 45 remain in a smooth cylindrical state, thereby eliminating the insertion interference caused by the slide key protrusion, ensuring that the quick-installation bushing 4 can smoothly complete the axial insertion and removal, and solving the assembly interference problem without changing the original quick-installation logic. The elastic telescopic structure consists of a radial groove 7 formed on the sliding bushing 45 and an internal spring 8. One end of the spring 8 abuts against the bottom of the radial groove 7, and the other end abuts against the inner end face of the corresponding slide key. The guide slope 9 generates a stable radial compressive force when the slide key passes through axially, pushing the slide key to compress the spring 8 and retract completely into the radial groove 7. After insertion, the elastic restoring force of the spring 8 pushes the slide key out and embeds it into the corresponding mating groove to form a stable sliding fit. This structure can realize the automatic extension and retraction of the slide key without external operation, which not only ensures the smooth and interference-free axial insertion of the quick-install bushing 4, but also automatically restores the transmission and guiding functions after insertion, simplifying the assembly process while improving the reliability and service life of the structure.

[0037] Please see Figures 11-15In this embodiment, during the cyclic rotation of the incubator 2 along the chain 13, the chains 13 on both sides of the support frame 1 mesh with the driving gear 11 and the driven gears 12 mounted on the support frame 1, forming a serpentine cyclic running trajectory with multiple horizontal sections and semi-circular rotating sections. The pin 5 is rigidly fixed at the connection of adjacent chain links 131 of the chain 13, and its spatial posture and radial orientation can completely follow the movement state of the chain 13 synchronously. The incubator 2 forms a rotational engagement with the pin 5 through the quick-release bushings 4 in the bearing seats 3 on both sides, and the center of gravity of the incubator 2 is always located at the pin. Vertically below the axis of shaft 5, under the influence of gravity, regardless of the movement state of chain 13, the incubator 2 will always maintain a horizontal posture with its opening facing vertically upwards. The spatial orientation of the bearing seat 3 and shaft hole 31, which are rigidly fixed to the side plate 21 of the incubator 2, will also remain fixed. When chain 13 runs in a horizontal straight section, the radial orientation of pin 5 remains constant, and there is no relative circumferential rotation between it and shaft hole 31. When chain 13 runs to the meshing area of ​​driven gear 12, it will complete a semi-circular rotational motion along the outer contour of driven gear 12. The running direction of chain 13 changes 180° during this process. With the chain 13 rotating in the opposite direction, the pin 5, rigidly fixed to the chain 13, will rotate 180° circumferentially around the axis of the driven gear 12 in sync with the rotation of the chain 13. Its radial orientation will also change synchronously by 180°. Meanwhile, the spatial orientation of the incubator 2, bearing seat 3, and shaft hole 31 remains fixed under gravity. This results in a 180° relative circumferential rotation between the pin 5, which rotates with the chain 13, and the shaft hole 31, which remains in a constant orientation. During operation, each time the incubator 2 passes a set of driven gears 12, the chain 13 will complete a 180° reversal of its direction of travel, and the pin 5 will synchronously complete a 180° rotation relative to the shaft hole 31. The driving slide key 52 is equidistantly fixed in the transmission groove 51 on the outer wall of the pin 5 along the circumferential direction, and can move circumferentially synchronously with the rotation of the pin 5. The driven slide key 452 is equidistantly fixed in the inner wall of the sliding sleeve 45 along the circumferential direction. In the initial installation state and after each reset, the initial circumferential position of the driven slide key 452 is symmetrical between the two adjacent sets of driving slide keys 52. At the same time, the driven slide key 452 and the driving slide key 52 are in the same axial position, ensuring that they can form a stable pushing fit when rotating circumferentially. When the pin 5 rotates circumferentially relative to the shaft hole 31 as the chain 13 passes through the driven gear 12, the pin 5 will drive the driving slide key 52 to rotate circumferentially around the axis. During the rotation, the circumferential end face of the driving slide key 52 will form a rigid push with the circumferential end face of the driven slide key 452. Since the driven slide key 452 and the sliding bushing 45 are rigidly fixedly connected, the circumferential pushing force of the driving slide key 52 will be transmitted to the sliding bushing 45 through the driven slide key 452, overcoming the sliding resistance between the guide slide key 451 and the guide tooth groove 33.The sliding bushing 45 rotates synchronously with the pin 5. Simultaneously, due to the different rotation directions of the chain 13 at different driven gears 12, the rotation direction of the pin 5 relative to the shaft hole 31 alternates. However, because the driven slide key 452 is always circumferentially symmetrical between adjacent sets of driving slide keys 52, regardless of whether the pin 5 rotates clockwise or counterclockwise, the driving slide key 52 can form a stable circumferential pushing engagement with the driven slide key 452. During equipment operation, as the incubator 2 passes each set of driven gears 12 along with the chain 13, the pin 5 completes one 180° rotation relative to the shaft hole 31. The circumferential rotation repeats the entire process of the active slide key 52 pushing the driven slide key 452 circumferentially and driving the sliding bushing 45 to rotate. During the rotation of the sliding bushing 45, the guide slide key 451 fixed on its outer wall will rotate circumferentially along the guide tooth groove 33 on the inner wall of the shaft hole 31. In the initial state, the guide slide key 451 is located at the axial end of the guide tooth groove 33 away from the telescopic airbag 44 and at the circumferential center symmetrical position of the guide tooth groove 33. During the rotation of the sliding bushing 45, it will synchronously drive the telescopic airbag 44 to rotate synchronously at the end connected to it, causing the telescopic airbag 44 to undergo circumferential shear torsion deformation and synchronously generate an axial force pointing towards the telescopic airbag 44. When the guide slide key 451 moves along the guide tooth groove 33 to the position of the corresponding tooth tip in the circumferential direction, its axial direction No longer constrained by the guide tooth groove 33, the axial contraction force generated by the telescopic airbag 44 will drive the guide slide key 451 to move axially from the end of the guide tooth groove 33 away from the telescopic airbag 44 to the end closer to the telescopic airbag 44. The driven slide key 452 will also complete the axial movement together with the sliding bushing 45. After the driven slide key 452 completes the axial movement, the circumferential pushing relationship between it and the driving slide key 52 is completely released, and the circumferential transmission constraint disappears. At this time, the telescopic airbag 44 will release the elastic potential energy stored in the previous torsional deformation process, drive the sliding bushing 45 to complete the circumferential reset rotation in the opposite direction, and at the same time, the guide slide key 451 will return to its initial position in the guide tooth groove 33, the driven slide key 452 will return to its initial position in the transmission groove 51, and the telescopic airbag 44 will return to its initial state. During the aforementioned process, when the telescopic airbag 44 undergoes circumferential shear torsional deformation, its tensile deformation transforms into uniform radial outward expansion deformation. This results in a symmetrical drum-shaped form where the expansion at both ends is small, while the expansion in the axial free section is the largest. This compresses the internal space of the shaft hole 31, creating positive pressure and expelling the gas from inside the shaft hole 31. When the telescopic airbag 44 returns to its initial shape, its radial expansion deformation recovers simultaneously, and the internal space of the shaft hole 31 expands, creating negative pressure and drawing in surrounding gas. This process repeats itself as the incubator 2 moves via the driven gear 12, ensuring a stable gas flow within the shaft hole 31. Furthermore, when the sliding bushing 45 rotates circumferentially to reset under the influence of the elastic potential energy released by the telescopic airbag 44, it simultaneously drives the axial fan blades 46 to rotate in the forward direction.When the axial fan blade 46 rotates forward, it generates a directional axial airflow towards the fixed bushing 43. The sliding bushing 45 rotates and resets periodically as the incubator 2 passes through the driven gear 12, thereby driving the axial fan blade 46 to rotate periodically and continuously generate a directional airflow. This airflow clears the gap between the quick-release bushing 4, the pin 5, and the shaft hole 31, discharging accumulated condensate and water vapor splashed in from the spray. Simultaneously, to ensure the sliding bushing 45 can be smoothly inserted into the shaft hole 31 for assembly, the maximum outer diameter of the axial fan blade 46 must be equal to or less than the outer diameter of the sliding bushing 45. The guide cone surface machined on the contact surface between the sliding bushing 45 and the axial fan blade 46 guides the airflow generated in the central area of ​​the axial fan blade 46 along the cone surface to diffuse to the axial outer wall of the sliding bushing 45, ensuring precise airflow coverage of the annular gap between the sliding bushing 45 and the shaft hole 31, forming a more uniform and effective axial blowing airflow.

[0038] In Embodiment 2, the main process is the same as in Embodiment 1. The main difference is that when installing the quick-release bushing 4, the guide key 451 on the outer wall of the sliding bushing 45 and the driven key 452 on its inner wall are radially pushed and squeezed into the radial groove 7 by the shaft hole 31 and the pin 5 respectively when the shaft hole 31 and the pin 5 are released. When the sliding bushing 45 is gradually pushed axially to move the guide key 451 and the driven key 452 to the guide tooth groove 33 and the transmission groove 51 respectively, since the guide key 451 and the driven key 452 are no longer radially squeezed by the shaft hole 31 and the pin 5, the spring 8 located in the radial groove 7 will radially push the guide key 451 and the driven key 452 out of the radial groove 7 respectively, so that the guide key 451 and the driven key 452 form a sliding fit between the guide tooth groove 33 and the transmission groove 51 respectively. When disassembling the quick-release bushing 4, first rotate the snap-fit ​​plate 41 to release the engagement between the snap-fit ​​plate 41 and the arc-shaped snap-fit ​​groove 221, and then pull the quick-release bushing 4 axially. During this process, the guide slide key 451 and the driven slide key 452 will both move axially and will respectively abut against the guide tooth groove 33 and the guide inclined surface 9 provided on the transmission slide groove 51. The guide inclined surface 9 will respectively generate a radial force on the guide slide key 451 and the driven slide key 452, pressing the guide slide key 451 and the driven slide key 452 into the radial slide groove 7, so that the quick-release bushing 4 can be pulled out smoothly.
