Description

Technical Field

[0001] This utility model relates to the field of hanging bag cultivation technology for wood ear fungus, specifically a circulating hanging cultivation device for wood ear fungus spawn bags. Background Technology

[0002] Black fungus, also known as cloud ear or mulberry ear, is an important edible fungus in my country, with a wide natural distribution and artificial cultivation.

[0003] Currently, the main method of mushroom cultivation using hanging bags involves suspending bags on fixed iron frames within plastic greenhouses, with ropes tied at equal intervals. Because the iron frames are fixed inside the greenhouse, the bags must be hung manually, one string of bags at a time, and harvesting also requires manual movement. Traditional mushroom cultivation mainly uses two methods: traditional ground planting and greenhouse-based hanging bag cultivation. Ground planting involves neatly arranging mushroom bags on level ground. Greenhouse-based hanging bag cultivation involves installing fixed cultivation frames within a plastic greenhouse, and then tying special hanging ropes (either double-line or triple-line) to the upper beams of the frame. The hanging ropes are fixed to the iron frames and cannot be moved once a string of bags is hung. Watering nozzles are installed on the frame beams. Since hanging and harvesting are both done manually, a circulating hanging cultivation device for mushroom bags is proposed. Utility Model Content

[0004] The purpose of this invention is to provide a circulating hanging cultivation device for wood ear fungus bags to solve the problems mentioned in the background art.

[0005] To achieve the above objectives, this utility model provides the following technical solution: a circulating hanging cultivation device for wood ear fungus bags, comprising a tensioning component, a power component, and a moving component;

[0006] The tensioning component is provided with a movable component on one side, and the movable component is provided with a hook for suspending the cultivation fungus bag on one side;

[0007] The tensioning assembly is provided with a power assembly on one side for providing a power source for the moving assembly;

[0008] The tensioning assembly includes a first track and a limiting frame. A fixed pulley is rotatably connected to one side of the bottom of the limiting frame, and a rope is wound around the outside of the fixed pulley. A fixing frame is fixed to one side of the top of the first track, and a first turntable located at the turning point of the first track is rotatably connected to one side of the bottom of the fixing frame.

[0009] A first rotating shaft is fixedly inserted into one side of the fixed frame, and a first bearing is fixedly sleeved at both ends of the first rotating shaft. A counterweight is connected to one end of the rope, and a limit block is fixed to one side of the first track.

[0010] Preferably, the tensioning assembly described above is provided with a support frame on one side, a plurality of second tracks are installed on one side of the support frame, and a second turntable located at the turning point of an adjacent second track is installed on one side of the support frame;

[0011] One of the second tracks is slidably sleeved on the outside of the first track at one end, and several second tracks are interconnected.

[0012] Preferably, the outer side of the first bearing is rolledly connected to the top of the limiting frame, the outer side of the fixing frame is slidably connected to the inner side of the limiting frame, the other end of the rope is fixed to one side of the limiting block, and the top of the limiting frame is fixed to one side of the support frame.

[0013] Preferably, the power assembly includes a servo motor and two second shafts, one of which has a first gear and a third gear fixedly sleeved on its outer side, and the other of which has a first gear fixedly sleeved on its outer side. The output shaft of the servo motor is fixed with a second gear.

[0014] Preferably, a first chain connects the second gear and the third gear, and a second chain connects the two first gears. Several positioning blocks are fixed to the outside of the second chain, and two limiting teeth are fixed to the outside of each positioning block.

[0015] Preferably, the aforementioned movable component includes a connecting block, the outer side of which has two insertion holes that are perpendicular to each other. A pin is inserted into the inner side of each insertion hole, and a first connecting frame and a second connecting frame are rotatably connected to the outer sides of the two pins, respectively.

[0016] Preferably, the inner wall of the second connecting frame is rotatably connected to a horizontally mounted third bearing, and a third rotating shaft is inserted into the middle of one side of the first connecting frame, with the outer ends of the third rotating shaft rotatably connected to second bearings.

[0017] Preferably, the outer side of the hook is sleeved on the outer side of the third rotating shaft, and the outer sides of the second and third bearings are slidably connected to the inner sidewalls of the first and second tracks.

[0018] Preferably, the top of the support frame is fixed with a rack, the bottom of the servo motor is fixed to the bottom of the inner wall of the rack, and the outer side of the second rotating shaft is mounted on the top side of the rack via a bearing seat.

[0019] Preferably, a through hole is provided on one side of the top of the second track, located below the second chain. When the second chain rotates, the limiting tooth engages with the outside of the third rotating shaft, causing the hook to be in a moving state.

[0020] When the counterweight moves downward, the first connecting frame and the second connecting frame are in a tensioned state;

[0021] A photoelectric sensor is installed on one side of the support frame, located on the hook side. A PLC controller is installed on one side of the support frame. The output terminal of the photoelectric sensor is electrically connected to the input terminal of the PLC controller, and the output terminal of the PLC controller is electrically connected to the input terminal of the servo motor.

[0022] Compared with the prior art, the present invention, by adopting the above technical solution, has the following technical effects:

[0023] First, by detecting the position of the hook through a photoelectric sensor and transmitting the signal to the PLC controller in real time, precise control of the servo motor rotation is achieved. The automated control enables the hook to stop moving according to preset instructions, thereby greatly improving the efficiency of hanging bags or harvesting of fungus. Workers do not need to manually control the stopping and starting of the hook, reducing manual intervention and improving the smoothness and speed of the overall operation process.

[0024] Second, when the gap between the first connecting frame and the second connecting frame increases, the counterweight pulls the first track and the first turntable to one side through the rope and fixed pulley system, thereby ensuring that the first connecting frame and the second connecting frame always maintain close contact during the movement, avoiding jamming or loosening caused by excessive gap, and ensuring the stability and reliability of the moving component when running under no-load.

[0025] Third, by moving up and down under the action of gravity, the counterweight not only helps to maintain the smooth operation of the moving components, but also effectively buffers the inertia during start-up and shutdown. When the moving components start or stop, the up and down movement of the counterweight can absorb or release some energy, thereby reducing the impact and vibration on the device and extending the service life of the equipment.

[0026] Fourth, the second chain drives multiple positioning blocks and limiting teeth to rotate. The meshing of the limiting teeth with the third rotating shaft ensures the smooth movement of the first and second connecting frames inside the first and second tracks, reducing vibration and shaking during movement and improving the stability of the overall system. Under the action of the second and third bearings, the degrees of freedom of the first and second connecting frames in the longitudinal and lateral directions are restricted, ensuring that they can only move along the direction of the track, reducing friction and contact between the moving components and other parts, thereby extending the service life of the equipment.

[0027] V. This device, through its three-dimensional hanging bag cultivation method, allows for the placement of more mushroom spawn bags on the same land area—more than three times that of traditional ground-grown mushrooms. This highly efficient cultivation method significantly increases mushroom yield, meeting the greater market demand. The greenhouse hanging bag production method for black mushrooms is less affected by weather, providing a relatively stable and controllable growth environment. This helps reduce the impact of external factors on mushroom growth, ensuring the purity and pollution-free quality of the mushrooms. High-quality mushrooms are more competitive in the market, bringing higher profits to enterprises. Combined with mechanized hanging bag cultivation and harvesting, this device achieves factory-style, mechanized mushroom cultivation, not only improving production efficiency but also reducing labor intensity, making mushroom production more standardized and controllable.

[0042] Example

[0043] Please see Figure 1-10 This utility model provides a technical solution: a circulating hanging cultivation device for wood ear fungus bags, including a tensioning component 2, a power component 3 and a moving component 7. A plurality of second tracks 4 are installed on one side of the support frame 1, and a second turntable 8 located at the turning point of an adjacent second track 4 is installed on one side of the support frame 1. One end of a second track 4 is slidably sleeved on the outside of a first track 25. The plurality of second tracks 4 are interconnected. The second turntable 8 is used to provide turning and direction change for the moving component 7 when it moves inside the second track 4.

[0044] The second track 4 is provided with a tensioning component 2 on one side; a moving component 7 is provided on one side of the tensioning component 2; a hook 5 for suspending the cultivation fungus bag is provided on one side of the moving component 7; a power component 3 for providing power to the moving component 7 is provided on one side of the tensioning component 2.

[0045] To ensure the stability of the moving component 7 during no-load operation, a tensioning component 2 is provided. The tensioning component 2 includes a first track 25 and a limiting frame 27. A fixed pulley 28 is rotatably connected to one side of the bottom of the limiting frame 27, and a rope 23 is wound around the outside of the fixed pulley 28. A fixing frame 210 is fixed to one side of the top of the first track 25, and a first turntable 22 located at the turning point of the first track 25 is rotatably connected to one side of the bottom of the fixing frame 210. Under the action of the fixed pulley 28, the rope 23 pulls the limiting block 29, the first track 25, the first turntable 22 and the fixing frame 210 to one side, so that the first track 25 slides outward to one side of the second track 4. At the same time, the first bearing 26 rolls on the top of the limiting frame 27. When the counterweight 21 moves downward, the first connecting frame 73 and the second connecting frame 74 are in a tensioned state.

[0046] To reduce the impact and vibration on the device, a first rotating shaft 24 is fixedly inserted into one side of the fixed frame 210. Both ends of the first rotating shaft 24 are fixedly sleeved with first bearings 26. The outer side of the first bearings 26 is rolledly connected to the top of the limiting frame 27, and the outer side of the fixed frame 210 is slidably connected to the inner side of the limiting frame 27. One end of the rope 23 is connected to a counterweight 21. A limiting block 29 is fixed to one side of the first track 25, and the other end of the rope 23 is fixed to one side of the limiting block 29. The top of the limiting frame 27 is fixed to one side of the support frame 1. The first turntable 22 moves to one side under the gravity of the counterweight 21, so that the first turntable 22 and the first track 25 pull the first connecting frame 73 and the second connecting frame 74, ensuring that the moving component 7 runs without jamming or loosening under no-load conditions, and avoiding friction between the moving component 7 and the inner walls of the first track 25 and the second track 4, which would generate a lot of noise.

[0047] To provide a power source for the movement of hook 5, a power assembly 3 is provided. The power assembly 3 includes a servo motor 31 and two second rotating shafts 34. One second rotating shaft 34 has a first gear 33 and a third gear 38 fixedly sleeved on its outer side, while the other second rotating shaft 34 has a first gear 33 fixedly sleeved on its outer side. The second gear 31 drives the third gear 38 to rotate via a first chain, and under the action of the second rotating shafts 34, it drives one of the first gears 33 to rotate. Under the action of the second chain, the two first gears 33 rotate in the same direction. A second gear 37 is fixed to the output shaft end of the machine 31. A first chain is connected between the second gear 37 and the third gear 38. A second chain is connected between the two first gears 33. Several positioning blocks 35 are fixed to the outside of the second chain. Two limiting teeth 36 are fixed to the outside of the positioning blocks 35. The second chain drives the multiple positioning blocks 35 and the limiting teeth 36 to rotate. The limiting teeth 36 mesh with the outside of the third rotating shaft 77 on one side of the through hole 6, so that the third rotating shaft 77 pushes the first connecting frame 73 and the second connecting frame 74 to move inside the first track 25 and the second track 4.

[0048] The moving component 7 includes a connecting block 75. Two insertion holes are provided on the outer side of the connecting block 75. The insertion holes are perpendicular to each other. A pin 76 is inserted into the inner side of the insertion hole. The outer sides of the two pins 76 are respectively rotatably connected to a first connecting frame 73 and a second connecting frame 74. A horizontally mounted third bearing 72 is rotatably connected to the inner wall of the second connecting frame 74. A third rotating shaft 77 is inserted into the middle of one side of the first connecting frame 73. The third rotating shaft 77 pushes the first connecting frame 73 and the second connecting frame 74 to move inside the first track 25 and the second track 4. The outer ends of the third rotating shaft 77 are rotatably connected to second bearings 71. The outer side of the hook 5 is sleeved on the outer side of the third rotating shaft 77. The outer sides of the second bearings 71 and the third bearings 72 are slidably connected to the inner side walls of the first track 25 and the second track 4.

[0049] The top of the support frame 1 is fixed with a frame 32, the bottom of the servo motor 31 is fixed to the bottom of the inner wall of the frame 32, the outer side of the second rotating shaft 34 is installed on the top side of the frame 32 through a bearing seat, and a through hole 6 is opened on the top side of the second track 4 located below the second chain. When the second chain rotates, the limiting tooth 36 meshes with the outer side of the third rotating shaft 77, so that the hook 5 is in a moving state. Under the action of the second bearing 71 and the third bearing 72, the longitudinal and lateral degrees of freedom of the first connecting frame 73 and the second connecting frame 74 are restricted, ensuring that other components do not come into contact with the upper and lower and left and right side plates of the track.

[0050] A photoelectric sensor is installed on one side of the support frame 1, located on the side of the hook 5. A PLC controller is installed on one side of the support frame 1. The output terminal of the photoelectric sensor is electrically connected to the input terminal of the PLC controller, and the output terminal of the PLC controller is electrically connected to the input terminal of the servo motor 31.

[0051] Working principle: When the mushroom spawn bags need to be hung for cultivation, the worker stands on the side of the photoelectric sensor on one side of the support frame 1. When the hook 5 moves into the detection range of the photoelectric sensor, the photoelectric sensor detects the hook 5 and sends an electrical signal to the PLC controller. The PLC controller controls the output shaft of the servo motor 31 to stop rotating. At this time, the hook 5 stops moving for a fixed time. When the hook 5 stops moving, the worker can hang the mushroom spawn bags or pick them. When multiple hooks 5 move to the photoelectric sensor in sequence, the mushroom spawn bags can be hung or picked continuously.

[0052] When the first connecting frame 73 and the second connecting frame 74 in the moving assembly 7 drive the hook 5 to move, the gap between the first connecting frame 73 and the second connecting frame 74 increases. At this time, the counterweight 21 pulls the rope 23 to move downward. Under the action of the fixed pulley 28, the rope 23 pulls the limiting block 29, the first track 25, the first turntable 22 and the fixed frame 210 to one side, causing the first track 25 to slide outward to one side of the second track 4. At the same time, the first bearing 26 rolls on the top of the limiting frame 27. The fixed frame 210 slides on the inner wall of the limiting frame 27. At this time, the first turntable 22 moves to one side under the gravity of the counterweight 21, so that the first turntable 22 and the first track 25 pull the first connecting frame 73 and the second connecting frame 74, ensuring that the moving component 7 runs without jamming or loosening under no-load conditions, avoiding friction between the moving component 7 and the inner walls of the first track 25 and the second track 4, which would generate a lot of noise. Under the gravity of the counterweight 21, the counterweight 21 moves up and down to do work to buffer the inertia of the moving component 7 when it starts and stops.

[0053] When the output shaft of the servo motor 31 rotates, the output shaft drives the second gear 37 to rotate, which in turn drives the third gear 38 to rotate via the first chain. Under the action of the second rotating shaft 34, the second gear 38 is driven to rotate. Under the action of the second chain, the two first gears 33 rotate in the same direction. The second chain drives multiple positioning blocks 35 and limiting teeth 36 to rotate. The limiting teeth 36 mesh with the outside of the third rotating shaft 77 on one side of the through hole 6, which pushes the first connecting frame 73 and the second connecting frame 74 to move inside the first track 25 and the second track 4. At this time, under the action of the second bearing 71 and the third bearing 72, the longitudinal and lateral degrees of freedom of the first connecting frame 73 and the second connecting frame 74 are restricted, ensuring that other components do not come into contact with or rub against the upper and lower and left and right side plates of the track.

[0054] This device enables higher yields of mushroom spawn bags in the same land area, with the number of bags used in vertical hanging bag cultivation being more than three times that of traditional ground-grown mushrooms. Furthermore, because the growth process of black fungus produced in greenhouses using hanging bags is less affected by weather, the quality is pure and pollution-free, resulting in high cultivation profits and considerable economic benefits. This device, combined with mechanized hanging bag cultivation and harvesting, achieves factory-style, mechanized cultivation of black fungus.

[0055] In summary, by detecting the position of hook 5 using a photoelectric sensor and transmitting the signal to the PLC controller in real time, precise control of the rotation of servo motor 31 is achieved. The automated control enables hook 5 to stop moving according to preset instructions, thereby greatly improving the efficiency of hanging or harvesting mushroom bags. Workers do not need to manually control the stopping and starting of hook 5, reducing manual intervention and improving the smoothness and speed of the overall operation process.

[0056] When the gap between the first connecting frame 73 and the second connecting frame 74 increases, the counterweight 21 pulls the first track 25 and the first turntable 22 to one side through the rope 23 and the fixed pulley 28 system, thereby ensuring that the first connecting frame 73 and the second connecting frame 74 always maintain close contact during the movement, avoiding jamming or loosening caused by excessive gap, and ensuring the stability and reliability of the moving component 7 when running under no-load.

[0057] The counterweight 21 moves up and down under the action of gravity, which not only helps to maintain the smooth operation of the moving component 7, but also effectively buffers the inertia when starting and stopping. When the moving component 7 starts or stops, the up and down movement of the counterweight 21 can absorb or release some energy, thereby reducing the impact and vibration on the device and extending the service life of the equipment.

[0058] The second chain drives multiple positioning blocks 35 and limiting teeth 36 to rotate. The meshing of the limiting teeth 36 with the third rotating shaft 77 ensures the smooth movement of the first connecting frame 73 and the second connecting frame 74 inside the first track 25 and the second track 4, reducing vibration and shaking during movement and improving the stability of the overall system. Under the action of the second bearing 71 and the third bearing 72, the freedom of the first connecting frame 73 and the second connecting frame 74 in the longitudinal and transverse directions is restricted, ensuring that they can only move along the direction of the track, reducing friction and contact between the moving component 7 and other components, thereby extending the service life of the equipment.

[0059] This device utilizes a three-dimensional hanging bag cultivation method, allowing for the placement of more mushroom spawn bags on the same land area—more than three times that of traditional ground-grown mushrooms. This highly efficient cultivation method significantly increases mushroom yield, meeting the greater market demand. The greenhouse hanging bag production method for black mushrooms is less affected by weather, providing a relatively stable and controllable growth environment. This helps reduce the impact of external factors on mushroom growth, ensuring the purity and pollution-free quality of the mushrooms. High-quality mushrooms are more competitive in the market, bringing higher profits to enterprises. Combined with mechanized hanging bag cultivation and harvesting, this device achieves factory-style, mechanized mushroom cultivation, not only improving production efficiency but also reducing labor intensity, making mushroom production more standardized and controllable.
