Description

Technical Field

[0001] This application relates to the field of microbial cultivation technology, and in particular to a spraying device for microbial cultivation. Background Technology

[0002] Cultivating fungi, such as bamboo fungus, in greenhouses is a common practice in modern agriculture. To ensure the normal growth of the fungi, they need to be provided with appropriate amounts of water or nutrient solution regularly. Currently, a common practice is to lay sprinkler pipes in the passageways between the soil layers inside the greenhouse, using these pipes to spray water and meet the fungi's water and nutrient requirements.

[0003] However, in practical applications, as the spawn grows, its height gradually increases. While the fixed-position spray pipes at the bottom can evenly spray the tips of the spawn and the soil, they often fail to effectively spray the top of the spawn, resulting in uneven spraying. This leads to excessive nutrient solution and water at the spawn roots, while the top of the spawn develops poorly, resulting in weak, easily broken mushrooms, thus affecting the quality of spawn growth. Secondly, the large number of spray pipes at the bottom not only increases planting costs but also makes soil preparation or tilling extremely inconvenient.

[0004] To address the aforementioned issues, a spraying device for mushroom cultivation has been designed. Utility Model Content

[0005] This application provides a spraying device for mushroom cultivation to solve the problem in related technologies where the bottom-laid spraying pipes fail to effectively spray the mushroom spawn, resulting in uneven spraying and affecting the quality of mushroom growth.

[0006] Firstly, a spraying device for mushroom cultivation is provided, comprising:

[0007] Two main beams are arranged opposite each other in the greenhouse, and a movable platform is slidably mounted on them. A spray section is provided at the bottom of the movable platform, and a hose for supplying liquid is connected to the spray section. The hose is connected to an external liquid supply mechanism for supplying liquid to the spray section. A driving component is provided on the main beam for driving the movable platform to move along the length of the main beam.

[0008] The spray unit includes two support frames that are disposed opposite each other at the bottom of the moving platform. Two water supply pipes are disposed directly opposite each other on the two support frames. Multiple spray plates are disposed between the outer sides of the two water supply pipes. The spray plates have water storage chambers inside. Multiple atomizing nozzles are disposed at the bottom of the spray plates. Multiple through holes communicating with the corresponding water storage chambers are opened on the water supply pipes. A T-joint is connected between one end of the two water supply pipes. The other end of the T-joint is connected to a flexible hose.

[0009] In some embodiments, a plurality of the spray plates are arranged along the length of the water supply pipe, the spray plates are arc-shaped, and the middle part of the spray plates is inclined downward.

[0010] In some embodiments, the movable platform includes opposing crossbeams, a fixed plate is disposed between the bottoms of the two crossbeams, and two support frames are disposed opposite each other at the bottom ends of the fixed plate;

[0011] Both ends of the crossbeam are provided with arc-shaped bends, and both ends of the arc-shaped bends are rotatably equipped with rollers, which are in contact with the side walls of the main beam.

[0012] In some embodiments, a winding mechanism is also included for winding and unwinding the hose;

[0013] The winding mechanism includes a fixed seat at one end of the main beam, two support seats opposite each other on the fixed seat, a winding drum rotatably disposed between the support seats, the winding drum having a cavity inside, a water supply pipe rotatably disposed at one end of the winding drum, and a sealing ring located inside the cavity on the water supply pipe.

[0014] The fixed base is equipped with a drive motor and a reducer. The output shaft of the drive motor is connected to the input shaft of the reducer, and the output shaft of the reducer is connected to the other end of the winding drum.

[0015] The hose is wound around the take-up drum, and the end of the hose away from the tee connector is connected to the cavity.

[0016] In some embodiments, the external liquid supply mechanism includes a liquid supply tank and a pump body disposed above the liquid supply tank, wherein the inlet of the pump body is connected to the liquid supply tank and the outlet of the pump body is connected to the other end of the water supply pipe.

[0017] In some embodiments, the drive component includes a housing disposed between two main beams, a lead screw rotatably disposed inside the housing, a transmission block threadedly connected to the lead screw, two transmission rods disposed opposite each other below the transmission block, and a mounting plate slidably disposed at the bottom of the housing;

[0018] The bottom of the mounting plate is connected to the top of the two crossbeams, and a sliding hole is provided at the bottom of the housing. The top of the mounting plate passes through the sliding hole and is connected to the transmission rod.

[0019] The housing is equipped with a second drive motor and a second reducer. The output shaft of the second drive motor is connected to the input shaft of the second reducer, and the output shaft of the second reducer is connected to either end of the lead screw.

[0033] To make the objectives, technical solutions, and advantages of the embodiments of this application clearer, the technical solutions of the embodiments of this application will be clearly and completely described below with reference to the accompanying drawings. Obviously, the described embodiments are only some embodiments of this application, not all embodiments. Based on the embodiments of this application, all other embodiments obtained by those skilled in the art without creative effort are within the scope of protection of this application.

[0034] This application provides a spraying device for mushroom cultivation, which solves the problem in related technologies where the bottom-laid spraying pipes fail to effectively spray the mushroom spawn, resulting in uneven spraying and affecting the quality of mushroom growth.

[0035] Please see Figures 1-3 A spraying device for mushroom cultivation includes: two main beams 1 arranged opposite each other in a greenhouse, with a movable platform 2 slidably mounted on them; a spraying section 3 is provided at the bottom of the movable platform 2; a hose 4 for supplying liquid is connected to the spraying section 3; the hose 4 is connected to an external liquid supply mechanism 5; the external liquid supply mechanism 5 is used to supply liquid to the spraying section 3; and a driving component 6 is provided on the main beams 1, which is used to drive the movable platform 2 to move along the length of the main beams 1.

[0036] The spray unit 3 includes two support frames 31 that are disposed opposite each other at the bottom of the moving platform 2. Two water supply pipes 32 are disposed directly opposite each other on the two support frames 31. Multiple spray plates 33 are disposed between the outer sides of the two water supply pipes 32. The spray plates 33 have water storage chambers 331 inside. Multiple atomizing nozzles 34 are disposed at the bottom of the spray plates 33. Multiple through holes 321 are opened on the water supply pipes 32 and communicate with the corresponding water storage chambers 331. A three-way connector 35 is connected between one end of the two water supply pipes 32. The other end of the three-way connector 35 is connected to the hose 4.

[0037] The driving component 6 installed on the main beam 1 provides power to the moving platform 2, driving the moving platform 2 to move along the length of the main beam 1, thereby driving the spray unit 3 at the bottom of the moving platform 2 to move inside the greenhouse, achieving large-area spray coverage.

[0038] The external liquid supply mechanism 5 is used to supply liquids such as nutrient solution and water to the spray unit 3. The liquid is delivered to the spray unit 3 through the hose 4 connected to the external liquid supply mechanism 5. One end of the hose 4 is connected to the three-way connector 35, and the other two ends of the three-way connector 35 are respectively connected to one end of the two water supply pipes 32, so the liquid enters the two water supply pipes 32.

[0039] The water supply pipe 32 has multiple through holes 321 and is connected to the water storage chamber 331 inside the spray plate 33. After the liquid enters the water supply pipe 32, it flows into the water storage chamber 331 of each spray plate 33 through the through holes 321. After the liquid reaches a certain pressure in the water storage chamber 331, it is sprayed out from the atomizing nozzle 34 in an atomized form to spray the bacteria below.

[0040] By arranging two main beams 1 opposite each other inside the greenhouse, and installing a movable platform 2 on them, with a spray unit 3 at the bottom of the platform 2, the spraying equipment can move within the greenhouse, expanding the spraying range and covering a larger area of ​​the mushroom cultivation area. Simultaneously, multiple spray plates 33 are installed between the outer sides of the two water pipes 32 in the spray unit 3, and each spray plate 33 has multiple atomizing nozzles 34 at its bottom, allowing the liquid to be sprayed evenly onto the mushroom spawn in an atomized form, ensuring that the spawn can fully absorb the liquid and promoting its growth.

[0041] The spray unit 3 is set at the bottom of the moving platform 2 by two support frames 31, and two water pipes 32 are set between the two support frames 31. The overall structure is relatively stable and can ensure that the spray unit 3 works normally and does not shake during the movement of the moving platform 2. The spray unit 3 is set above the greenhouse by the support frames 31 and the moving platform 2, which is conducive to the trimming and tilling of the soil inside the greenhouse.

[0042] The hose 4 is connected to the external liquid supply mechanism 5 to supply liquid to the spray unit 3. The hose 4 has a certain degree of flexibility, which can adapt to the movement of the moving platform 2 and will not cause the liquid supply to be interrupted due to the movement of the moving platform 2, thus ensuring the continuity and stability of the liquid supply. At the same time, the hose 4 is connected to the two water supply pipes 32 through the three-way connector 35, which simplifies the connection structure of the liquid supply pipeline and makes the liquid supply more convenient.

[0043] like Figure 3 and Figure 8 As shown, specifically, in this embodiment, multiple spray plates 33 are arranged along the length of the water supply pipe 32, the spray plates 33 are arc-shaped, and the middle part of the spray plates 33 is inclined downward.

[0044] The spray plate 33 has an arc-shaped structure with its center tilted downwards, allowing the liquid to flow naturally towards the center and gather within the water storage chamber 331 before being evenly sprayed from the atomizing nozzles 34. This ensures that the amount of liquid sprayed from each atomizing nozzle 34 is relatively consistent, thereby improving the uniformity of the spray. Simultaneously, the liquid can flow quickly to the atomizing nozzles 34, reducing the residence time of the liquid within the water storage chamber 331 and improving spray efficiency.

[0045] The curved spray plate 33 allows the liquid sprayed from the atomizing nozzle 34 to be sprayed at a wider angle, reducing spray dead zones. Compared with flat spray plates, the curved spray plate 33 can better adapt to spraying needs in different directions and angles, ensuring that all the microorganisms in the greenhouse are fully sprayed, which is beneficial to the growth and development of the microorganisms.

[0046] like Figure 3 and Figure 7 As shown, in one embodiment, the movable platform 2 includes two opposing crossbeams 21, a fixed plate 22 is provided between the bottoms of the two crossbeams 21, and two support frames 31 are disposed opposite to each other at the bottom ends of the fixed plate 22; both ends of the crossbeams 21 are provided with arc-shaped bends 23, and both ends of the arc-shaped bends 23 are rotatably provided with rollers 24, and the rollers 24 are in contact with the side wall of the main beam 1.

[0047] The bottom of the two crossbeams 21 is connected by a fixing plate 22, providing a stable installation base for the spray unit 3. Two support frames 31 are set at both ends of the bottom of the fixing plate 22 to support components such as the water supply pipe 32 and the spray plate 33 in the spray unit 3.

[0048] The curved elbows 23 at both ends of the crossbeam 21 serve as connectors and guides. The rollers 24 at both ends of the curved elbows 23 rotate and fit against the side walls of the main beam 1. When the drive unit 6 operates, it generates driving force, and the moving platform 2 moves along the length of the main beam 1 by rolling the rollers 24 on the side walls of the main beam 1. The curved elbows 23 help to better match the rollers 24 with the side walls of the main beam 1, reducing jamming and resistance during movement and ensuring smooth movement.

[0049] like Figure 1 and Figure 6As shown, in a preferred embodiment, it further includes a winding mechanism 7, which is used to wind and unwind the hose 4. The winding mechanism 7 includes a fixed seat 71 disposed at one end of the main beam 1, two support seats 72 disposed opposite each other on the fixed seat 71, and a winding drum 73 rotatably disposed between the support seats 72. The winding drum 73 has a cavity 74 inside, and a water supply pipe 75 is rotatably disposed at one end of the winding drum 73. A sealing ring 76 located inside the cavity 74 is disposed on the water supply pipe 75. A drive motor 77 and a reducer 78 are disposed on the fixed seat 71. The output shaft of the drive motor 77 is connected to the input shaft of the reducer 78, and the output shaft of the reducer 78 is connected to the other end of the winding drum 73. The hose 4 is wound around the winding drum 73, and the end of the hose 4 away from the tee connector 35 is connected to the cavity 74.

[0050] When the moving platform 2 moves on the main beam 1, the hose 4 is required for winding and unwinding. The drive motor 77 starts, and its output shaft transmits power to the input shaft of the reducer 78. After the reducer 78 reduces and increases the torque, the output shaft of the reducer 78 drives the take-up drum 73 to rotate between the two support seats 72. During the winding process, as the take-up drum 73 rotates, the hose 4 gradually wraps around the take-up drum 73. Since the end of the hose 4 away from the tee connector 35 is connected to the cavity 74 inside the take-up drum 73, liquid can enter the cavity 74 of the take-up drum 73 through the water supply pipe 75, and then flow from the cavity 74 into the hose 4 to achieve liquid supply.

[0051] The sealing ring 76 located inside the cavity 74 on the water supply pipe 75 can ensure the sealing of the connection between the water supply pipe 75 and the winding drum 73 and prevent liquid leakage.

[0052] When the moving platform 2 moves in the reverse direction, the take-up drum 73 rotates in the reverse direction under the drive of the drive motor 77 and the reducer 78. The hose 4 is gradually released from the take-up drum 73 to adapt to the moving distance of the moving platform 2, ensuring that the hose 4 always maintains a suitable length and will not be tangled due to being too long or pulled and damaged due to being too short.

[0053] By incorporating the winding mechanism 7, the automatic winding and unwinding of the hose 4 is achieved, eliminating the need for manual operation and significantly improving work efficiency. Simultaneously, automated winding and unwinding ensures the accuracy and stability of the hose 4's winding and unwinding, avoiding errors and mistakes that may arise from manual operation.

[0054] The flexible hose 4 is wound around the winding drum 73, allowing it to be neatly rolled up when not in use, saving space inside the greenhouse and making the greenhouse layout more rational. At the same time, the neatly rolled-up flexible hose 4 is also easier to manage and maintain, reducing the risk of damage and aging caused by messy placement.

[0055] The winding mechanism 7 can automatically adjust the length of the hose 4 according to the movement of the moving table 2, ensuring that the hose 4 is always in a suitable state and will not cause problems such as tangling or pulling of the hose 4 due to the movement of the moving table 2, thus ensuring the normal operation of the spraying equipment.

[0056] like Figure 9 As shown, the external liquid supply mechanism 5 in this embodiment includes a liquid supply tank 51 and a pump body 52 disposed above the liquid supply tank 51. The inlet of the pump body 52 is connected to the liquid supply tank 51, and the outlet of the pump body 52 is connected to the other end of the water supply pipe 75.

[0057] The liquid supply tank 51 serves as a storage container for liquids such as nutrient solution and water, and is used to hold the liquid to be sprayed. The liquid supply tank 51 is equipped with a feeding port for adding water and nutrient solution.

[0058] The pump body 52 is located above the liquid supply tank 51, and its inlet is connected to the liquid supply tank 51. When the pump body 52 is started, it will generate suction in the liquid supply tank 51, drawing the liquid in the liquid supply tank 51 into the pump body 52. ​​The pump body 52 pressurizes the liquid drawn in, and after it has a certain pressure, it is discharged from the outlet of the pump body 52. ​​The pressurized liquid enters the cavity 74 of the winding drum 73 through the water supply pipe 75, and is then transported to the spray section 3 through the hose 4 connected to the cavity 74. Finally, it is sprayed out from the atomizing nozzle 34 to realize the spraying operation of the bacteria.

[0059] like Figure 4 and Figure 5 As shown, the driving component 6 in this embodiment includes a housing 61 disposed between two main beams 1. A lead screw 62 is rotatably disposed inside the housing 61, and a transmission block 63 is threadedly connected to the lead screw 62. Two transmission rods 64 are disposed opposite each other below the transmission block 63. A mounting plate 65 is slidably disposed at the bottom of the housing 61. The bottom of the mounting plate 65 is connected to the top of the two crossbeams 21. A sliding hole is formed at the bottom of the housing 61, and the top of the mounting plate 65 passes through the sliding hole and connects to the transmission rods 64. A second drive motor and a second reducer are disposed on the housing 61. The output shaft of the second drive motor is connected to the input shaft of the second reducer, and the output shaft of the second reducer is connected to either end of the lead screw 62. A threaded hole adapted to the lead screw 62 is formed inside the transmission block 63.

[0060] When the second drive motor starts, its output shaft transmits power to the input shaft of the second reducer. After the second reducer reduces and increases the torque, it drives the lead screw 62 to rotate inside the housing 61 through the output shaft of the second reducer. Since the transmission block 63 is threadedly connected to the lead screw 62, when the lead screw 62 rotates, according to the lead screw nut transmission principle, the transmission block 63 will move linearly along the axial direction of the lead screw 62. The two transmission rods 64 arranged opposite to each other below the transmission block 63 are connected to the top of the mounting plate 65, and the bottom of the mounting plate 65 is connected to the top of the two crossbeams 21. When the transmission block 63 moves, it will drive the mounting plate 65 to slide at the bottom of the housing 61 through the transmission rods 64, thereby driving the entire moving platform 2 to move along the length of the main beam 1, realizing the position adjustment of the spraying section 3 inside the greenhouse.
