Description

Technical Field

[0001] The invention relates to the technical field of edible fungus cultivation, in particular to a fixing device for an edible fungus cultivation bag. Background Art

[0002] Edible fungus cultivation bags play a vital role in the production process of edible fungi. Their main function is to carry the culture medium and provide a suitable environment for the mycelium to grow. Traditional edible fungus cultivation bags are generally made of plastic or polyester materials, and the bag mouth is usually sealed by hand pinching, tying or winding. In order to ensure the healthy growth of edible fungi, the sealing of the bag mouth is very important, because it directly affects the control of the culture environment, such as humidity, temperature and airflow.

[0003] The existing method of fixing the cultivation bag is to extend the cylinder into the bag opening of the cultivation bag, and then clamp the side of the bag opening on the outer wall of the cylinder from the outside. Although this method has good fixing firmness, it is easy to cause wrinkles at the bag opening and form gaps, resulting in poor sealing.

[0004] Therefore, those skilled in the art have proposed a fixing device for edible fungus cultivation bags to solve the above problems. Summary of the invention

[0005] In view of the deficiencies in the prior art, the present invention provides a fixing device for a mushroom cultivation bag, which solves the problems raised in the above-mentioned background technology.

[0006] To achieve the above objectives, the present invention is implemented through the following technical solutions: a fixing device for an edible fungus cultivation bag, comprising a plurality of planting shells, each of which is fixedly mounted with a mounting frame on the top, a driving screw being movably connected to the top through hole of the planting shell through a bearing, a threaded frame being threadedly connected to the outer surface of the driving screw, a support frame being fixedly connected to the bottom of the threaded frame, a second swing arm being rotatably mounted on the outer periphery of the support frame, a mounting plate being slidably connected to the outer surface of the threaded frame, a first swing arm being rotatably connected to the bottom periphery of the mounting plate, the driving screw being rotated to allow the threaded frame to move up and down along the outer surface of the driving screw, and the support frame being driven to move synchronously while the threaded frame moves, and at this time, the second swing arm is expanded outwardly under the auxiliary traction of the first swing arm until the bag mouth of the edible fungus cultivation bag is fixed.

[0007] Preferably, a driving motor is installed on the top of one of the planting shells, the driving end of the driving motor is fixedly connected to a driving shaft, the outer surface of the driving shaft is fixedly connected to a plurality of bevel gears 2, and the outer sides of the bevel gears 2 are meshedly connected with bevel gears 3 and 1 in sequence.

[0008] Preferably, a transmission shaft is movably connected to the middle inner side of the mounting frame via a bearing, a driving gear is fixedly connected to the top of the transmission shaft, two driving racks are slidably connected to the inner side of the mounting frame, a connecting frame is fixedly connected to the bottom of the driving rack, and a support ring is fixedly installed at the bottom end of the connecting frame.

[0009] Preferably, the outer sides of the driving gears are meshedly connected with the outer sides of the two driving racks, and the longitudinal section of the supporting ring is configured as an arc surface.

[0010] Preferably, two limiting grooves are provided on the lower surface of the mounting bracket, and the outer side of the driving rack is slidably connected to the inner wall of the limiting groove.

[0011] Preferably, the end of the bevel gear three is fixedly connected to the bottom end of the transmission shaft, and the bevel gear one is fixedly connected to the top of the driving screw.

[0012] Preferably, one end of the driving shaft is rotatably connected to a mounting block, and the mounting block is fixedly connected to the top of one of the planting shells.

[0013] Preferably, a planting cavity is provided inside the planting shell, a through groove having the same size as that at the mouth of the edible fungus cultivation bag is provided at the bottom of the planting shell, and adjustment holes are equidistantly provided on the upper surface of the planting shell.

[0014] Preferably, the ends of the four first swing arms are rotatably connected to the outer sides of the plurality of second swing arms respectively, and a support plate is fixedly mounted on the bottom of the second swing arms.

[0015] A method for using a fixing device for an edible fungus cultivation bag comprises the following steps:

[0016] Step 1. In the initial state, the plurality of support plates are at the center of the bottom of the planting shell and are in an inwardly approaching state. At this time, the bag opening of the edible fungus cultivation bag is placed on the outer side of the support plate. At this time, the driving motor drives the driving shaft to rotate. The rotation of the driving shaft drives the plurality of bevel gears 2 to rotate, and then drives the plurality of bevel gears 1 meshingly connected thereto to rotate. The rotation of the bevel gear 1 drives the driving screw to rotate synchronously. At this time, the threaded frame moves up and down along the outer surface of the driving screw. The threaded frame moves and drives the support frame to move synchronously. At this time, the second swing arm is extended outward under the auxiliary traction of the first swing arm until the bag opening of the edible fungus cultivation bag is opened and fixed;

[0017] Step 2: When bevel gear 2 rotates, it will drive the meshing bevel gear 3 to rotate synchronously. At this time, bevel gear 3 will drive the transmission shaft to rotate synchronously. The rotation of the transmission shaft drives the driving gear to rotate. At this time, the two driving racks move closer to or farther away from each other as the driving gear rotates, thus driving the two connecting racks.

[0018] Synchronous movement, when the connecting frame moves, the supporting ring is driven to move, so that the supporting ring can fit tightly at the opening of the cultivation bag, increasing the sealing between the support plate and the opening of the cultivation bag;

[0019] Step 3: The cultivation bag can only be connected to the external space through a plurality of adjustment holes, and the edible fungus cultivation environment in the cultivation bag is adjusted through the adjustment holes and the external environment adjustment device.

[0020] The present invention provides a fixing device for edible fungus cultivation bags, which has the following beneficial effects:

[0021] 1. The present invention uses a plurality of support plates and a support ring to extend into the inner side and the outer side of the cultivation bag respectively, and the fit of the two realizes the clamping and fixing of the bag opening of the cultivation bag, and the clamping is firm, so as to ensure the sealing of the bag opening, ensure the accuracy of adjusting the edible fungus cultivation environment, and at the same time cooperate with the vent hole and the external environment adjustment device to adjust the edible fungus cultivation environment in the cultivation bag.

[0022] 2. The present invention can automatically open the mouth of the edible fungus cultivation bag, greatly improving the operating efficiency and work quality during the cultivation process. In the traditional edible fungus cultivation process, the mouth of the cultivation bag needs to be opened and fixed manually, which is time-consuming and labor-intensive, and easily leads to uneven opening of the bag mouth, affecting the growth environment and yield of the edible fungi. However, through the ingenious mechanical design, the present device can accurately and evenly open and fix the mouth of the cultivation bag, ensuring that each cultivation bag is evenly ventilated, avoiding poor air circulation caused by poor bag closure, thereby providing better environmental conditions for the normal growth of edible fungi.

DETAILED DESCRIPTION

[0031] The following will be combined with the drawings in the specification of the present invention to clearly and completely describe the technical solutions in the embodiments of the present invention. Obviously, the described embodiments are only part of the embodiments of the present invention, not all of the embodiments. Based on the embodiments of the present invention, all other embodiments obtained by ordinary technicians in this field without creative work are within the scope of protection of the present invention.

[0032] Please see attached Figure 1 - Attachment Figure 7 The embodiment of the present invention provides a fixing device for a mushroom cultivation bag, comprising a plurality of planting shells 1, wherein a mounting frame 2 is fixedly mounted on the top of each planting shell 1, a driving screw 601 is movably connected to the top through hole of the planting shell 1 through a bearing, a threaded frame 603 is threadedly connected to the outer surface of the driving screw 601, a support frame 605 is fixedly connected to the bottom of the threaded frame 603, a second swing arm 606 is rotatably mounted on the outer periphery of the support frame 605, a mounting plate 602 is slidably connected to the outer surface of the threaded frame 603, a first swing arm 604 is rotatably connected to the bottom periphery of the mounting plate 602, the driving screw 601 is rotated to allow the threaded frame 603 to move up and down along the outer surface of the driving screw 601, and the support frame 605 is driven to move synchronously while the threaded frame 603 moves, at which time the second swing arm 606 is extended outwards under the auxiliary traction of the first swing arm 604 until the bag mouth of the mushroom cultivation bag is fixed. The ends of the four first swing arms 604 are rotatably connected to the outer sides of the plurality of second swing arms 606 , respectively, and a support plate 9 is fixedly mounted on the bottom of the second swing arms 606 .

[0033] Specifically, the planting shell 1 is used to accommodate and fix the components of the entire device. The threaded frame 603 has a threaded structure on the outside, which matches the thread of the driving screw 601 and can move up and down along the driving screw 601. The threaded frame 603 is the main moving component, responsible for promoting the movement of other connecting components. The support frame 605 is fixed to the bottom of the threaded frame 603. The function of the support frame 605 is to provide stability, ensure that other components can move safely, and keep the cultivation bag mouth fixed. Four second swing arms 606 are installed on the outside of the support frame 605, and the movement mode of these arms is rotation. They are expanded or contracted by rotation to ensure that the bag mouth of the edible fungus cultivation bag can be extended and fixed. The first swing arm 604 is installed on the outer surface of the threaded frame 603 and is responsible for guiding the expansion of the second swing arm 606. They are connected to the outer end of the second swing arm 606, and the lever principle is used to assist the second swing arm 606 to expand and further fix the cultivation bag.

[0034] When the device is in the initial state, the plurality of support plates 9 are located at the center of the bottom of the planting shell 1 and they are folded inwards. At this time, the user places the bag opening of the edible fungus cultivation bag on the outside of the support plates 9.

[0035] The driving motor 301 starts to work, driving the driving shaft 302 to rotate, and through a series of gear transmission systems (bevel gear 1 303 and bevel gear 2 304), the driving screw 601 rotates. The rotation of the driving screw 601 drives the threaded frame 603 to move up and down, thereby driving the support frame 605 to move synchronously. The threaded frame 603 drives the support frame 605 to move, thereby driving the second swing arm 606 to expand outward. When the second swing arm 606 is expanded to a certain angle, they will open and fix the bag opening of the cultivation bag.

[0036] Through this process, the mouth of the edible fungus cultivation bag can be fixed, which is convenient for subsequent cultivation and operation.

[0037] Advantages: This structure can automatically open the mouth of the edible fungus cultivation bag, greatly improving the operating efficiency and work quality during the cultivation process. In the traditional edible fungus cultivation process, the mouth of the cultivation bag needs to be opened and fixed manually, which is time-consuming and labor-intensive, and easily leads to uneven opening of the bag, affecting the growth environment and yield of the edible fungi. However, this device can accurately and evenly open and fix the mouth of the cultivation bag through clever mechanical design, ensuring that each cultivation bag is evenly ventilated, avoiding poor air circulation caused by poor bag closure, and thus providing better environmental conditions for the normal growth of edible fungi.

[0038] A driving motor 301 is installed on the top of one of the planting shells 1, and a driving shaft 302 is fixedly connected to the driving end of the driving motor 301. A plurality of bevel gears 2 304 are fixedly connected to the outer surface of the driving shaft 302, and bevel gears 3 305 and bevel gears 1 303 are meshed and connected to the outer side of the bevel gears 2 304 in sequence. The end of the bevel gear 3 305 is fixedly connected to the bottom end of the transmission shaft 403, and the bevel gear 1 303 is fixedly connected to the top of the driving screw 601. The transmission shaft 403 is movably connected to the middle part of the inner side of the mounting frame 2 through a bearing, and the top of the transmission shaft 403 is fixedly connected to the driving gear 405. Two driving racks 404 are slidably connected to the inner side of the mounting frame 2, and the bottom of the driving rack 404 is fixedly connected to the connecting frame 401, and the bottom end of the connecting frame 401 is fixedly installed with a support ring 402. The outer sides of the driving gears 405 are meshed and connected to the outer sides of the two driving racks 404, and the longitudinal section of the support ring 402 is set as an arc surface.

[0039] Specifically, the rotation of the drive motor 301 is transmitted to other mechanical parts through the drive shaft 302, and a plurality of bevel gears 304 are fixedly connected to the outer surface of the shaft. The mounting frame 2 is a bracket that supports all mechanical parts. There are bearings in the mounting frame 2 to allow the transmission shaft 403 to rotate freely. Drive racks 404 are also installed on the inner side of the mounting frame 2, and these racks are engaged with the drive gear 405. The movement of the two drive racks 404 drives the connecting frame 401 to move synchronously. A support ring 402 is fixedly installed at the bottom end of the connecting frame 401. The support ring 402 can eventually fit at the bag opening of the cultivation bag through synchronous movement with the connecting frame 401, helping to seal the bag opening and improve the sealing. The longitudinal section of the support ring 402 is arc-shaped, which helps to provide a better sealing effect.

[0040] Power transmission process: The driving motor 301 first provides power, which is transmitted to the bevel gear 2 304 through the driving shaft 302. As the bevel gear 2 304 rotates, it drives the bevel gear 3 305 to rotate synchronously. The rotation of the bevel gear 3 305 then drives the transmission shaft 403 to rotate, and the rotation of the transmission shaft 403 drives the driving gear 405 to rotate. After the driving gear 405 rotates, it meshes with the two driving racks 404, causing the racks to move closer or farther from each other, thereby driving the connecting frame 401 to move.

[0041] As the connecting frame 401 moves, the support ring 402 fixed at the bottom of the connecting frame 401 will also move together, and finally the support ring 402 will fit closely to the bag opening of the cultivation bag. The function of the support ring 402 is to enhance the sealing of the bag opening of the cultivation bag, ensure the isolation between the bag opening and the external environment, and avoid the influence of the external environment. The arc design of the support ring 402 helps to better adapt to the curved surface of the bag opening and provide a tighter seal.

[0042] The cultivation bag itself has a plurality of adjustment holes 5, which are used to be connected to the external environment. Through the adjustment holes 5, the environmental conditions (such as temperature, humidity, etc.) in the cultivation bag can be adjusted to provide a suitable growth environment for the cultivation of edible fungi.

[0043] Two limiting grooves 7 are formed on the lower surface of the mounting frame 2 , and the outer side of the driving rack 404 is slidably connected to the inner wall of the limiting groove 7 .

[0044] Specifically, the mounting frame 2 serves as a supporting device responsible for fixing the drive system and related mechanical components. Two limit grooves 7 are provided on the lower surface of the mounting frame 2. The shape and size of the limit grooves 7 match the size of the outer side of the driving rack 404 to ensure that the rack and the groove are accurately matched. Through this design, the movement range of the driving rack 404 during the movement process can be limited. The design of the limit groove 7 not only effectively limits the longitudinal displacement of the driving rack 404, but also plays a guiding and positioning role, ensuring that the rack moves smoothly along a predetermined trajectory and preventing excessive movement. The sliding connection between the inner wall of the limit groove 7 and the outer side of the rack enables the rack to slide smoothly in the groove while avoiding jamming or wear caused by excessive friction.

[0045] Specifically, the function of the limiting groove 7 is to provide the driving rack 404 with a movable space.

[0046] One end of the driving shaft 302 is rotatably connected to a mounting block 8 , and the mounting block 8 is fixedly connected to the top of one of the planting shells 1 .

[0047] Specifically, the drive shaft 302 is one of the key transmission components of the whole device. It is powered by the drive motor 301 through its drive end and transmitted to the subsequent gear system.

[0048] One end of the drive shaft 302 is rotatably connected to the mounting block 8. This connection method uses bearings, pins or other rotating connection devices to ensure that the drive shaft 302 can rotate freely while the mounting block 8 remains fixed in its corresponding position. The mounting block 8 plays a supporting and positioning role. It bears the rotational force from the drive shaft 302 and transmits it to the subsequent mechanical parts through its own structure.

[0049] A planting cavity is provided inside the planting shell 1 , a through groove having the same size as that at the mouth of the edible fungus cultivation bag is provided at the bottom of the planting shell 1 , and adjustment holes 5 are provided at equal intervals on the upper surface of the planting shell 1 .

[0050] Specifically, the planting shell 1 is a container for cultivating edible fungi, so that it can provide a suitable environment for the growth of edible fungi. The planting cavity is an area that provides a growth space for fungi. The size and shape of this cavity will be designed according to the type and growth requirements of the edible fungi to ensure that the fungi have enough space to expand and reproduce.

[0051] The size and shape of the through groove match the opening of the edible fungus cultivation bag. The edible fungus cultivation bag is a bag filled with fungus strains and culture medium. The fungus needs to start growing from the bag opening and expand outward. The presence of the through groove ensures that the planting shell 1 can be tightly docked with the bag opening of the cultivation bag, ensuring good contact between the fungus strains in the cultivation bag and the external environment. The through groove is designed to be consistent in size with the bag opening, which is convenient for the growth of edible fungi and air circulation, avoiding oxygen deficiency caused by sealing, and can provide necessary humidity control to promote the growth of mycelium.

[0052] A number of adjustment holes 5 are evenly distributed on the upper surface of the planting shell 1. The positions and sizes of these holes are carefully designed to facilitate environmental adjustment during the cultivation process. The main functions of the adjustment holes 5 include the following:

[0053] Air circulation: The growth of edible fungi requires a certain amount of oxygen, but at the same time, it cannot be over-ventilated. The regulating holes 5 can help regulate the air circulation, maintain appropriate gas exchange, and avoid excessively low or high humidity.

[0054] Temperature and humidity control: The adjustment holes 5 can also help adjust the temperature and humidity to meet the best conditions for fungus growth. When the temperature is too high or the humidity is too low, the user can adjust the environmental conditions by adjusting the opening and closing of these holes to promote the healthy growth of edible fungi.

[0055] Reduced mold growth: Proper ventilation can prevent excessive moisture that can lead to mold growth, thereby reducing the risk of disease in mushroom cultivation.

[0056] The design of the planting shell 1 of the present invention not only focuses on the growth space of the fungus species, but also fully considers the influence of the external environment on the cultivation process. The through-groove design at the bottom enables the edible fungus cultivation bag and the planting shell 1 to form a tightly integrated system, while the adjustment holes 5 on the upper surface provide users with the possibility of flexible control of the environment. By reasonably adjusting the position and opening and closing of these holes, the grower can easily adjust the temperature, humidity and ventilation conditions, thereby providing more superior growth conditions for edible fungi.

[0057] A method for using a fixing device for an edible fungus cultivation bag comprises the following steps:

[0058] Step 1, in the initial state, the plurality of support plates 9 are at the center of the bottom of the planting shell 1 and are in an inwardly close state. At this time, the bag mouth of the edible fungus cultivation bag is placed on the outer side of the support plate 9. At this time, the driving motor 301 drives the driving shaft 302 to rotate. The rotation of the driving shaft 302 drives the plurality of bevel gears 2 304 to rotate, and then drives the plurality of bevel gears 1 303 meshingly connected thereto to rotate. The rotation of the bevel gear 1 303 drives the driving screw 601 to rotate synchronously. At this time, the threaded frame 603 moves up and down along the outer surface of the driving screw 601, and drives the support frame 605 to move synchronously while the threaded frame 603 moves. At this time, the second swing arm 606 is expanded outward under the auxiliary traction of the first swing arm 604 until the bag mouth of the edible fungus cultivation bag is opened and fixed;

[0059] Step 2, when the bevel gear 2 304 rotates, it will drive the meshing bevel gear 3 305 to rotate synchronously, at this time, the bevel gear 3 305 will drive the transmission shaft 403 to rotate synchronously, and the rotation of the transmission shaft 403 drives the driving gear 405 to rotate. At this time, the two driving racks 404 are close to or away from each other as the driving gear 405 rotates, thereby driving the two connecting frames 401 to move synchronously, and the support ring 402 is driven to move while the connecting frame 401 moves, so that the support ring 402 can fit closely at the bag opening of the cultivation bag, thereby increasing the sealing performance between the support plate 9 and the bag opening of the cultivation bag;

[0060] Step 3: The cultivation bag can only be connected to the external space through the multiple adjustment holes 5, and the edible fungus cultivation environment in the cultivation bag is adjusted through the adjustment holes 5 and the external environment adjustment equipment.

[0061] In summary, the present invention achieves clamping and fixing of the bag opening of the cultivation bag by fixing the inner and outer clips of the cultivation bag, and the clamping is firm, thereby ensuring the sealing of the bag opening and the accuracy of adjusting the edible fungus cultivation environment. At the same time, the vent hole and the external environment adjustment device are used to adjust the edible fungus cultivation environment in the cultivation bag.

[0062] Although embodiments of the present invention have been shown and described, it will be appreciated by those skilled in the art that various changes, modifications, substitutions and variations may be made to the embodiments without departing from the principles and spirit of the present invention, and that the scope of the present invention is defined by the appended claims and their equivalents.
