Description

Technical Field

[0001] This utility model relates to the field of king oyster mushroom culture bottle filling technology, specifically an automatic bottle filling device for king oyster mushroom culture medium. Background Technology

[0002] King oyster mushroom is a rare edible fungus with a gray to light brown cap and a thick, white stem. It has a tender texture similar to abalone and is rich in protein and various amino acids. Its growth depends on artificial cultivation. A culture medium made primarily of sawdust and cottonseed hulls is sterilized and then inoculated with spawn. The spawn is then allowed to grow in a dark environment at 15-20℃. Once the mycelium has fully colonized the mushroom, the mushrooms are induced by controlling the temperature and humidity. The culture medium is then bottled. Because the bottle has good sealing properties, it reduces contamination by other microorganisms. The regular space makes it easy to control the cultivation conditions, such as humidity and oxygen content. It also fixes the culture medium, preventing the structure from becoming loose during the mycelium growth process. At the same time, it facilitates the management and harvesting of the mushrooms later on. This is a common method of industrial cultivation.

[0003] The existing automatic bottle filling device for king oyster mushroom culture medium first stores the pre-treated culture medium (such as a mixture of sawdust, cottonseed hulls, etc.) in the storage tank. The material is then transported from the storage tank to the filling host via a screw conveyor. Empty bottles are fed into the device by a conveyor belt and are precisely positioned below the filling port by a slot or robotic arm. Then, the quantitative valve is opened and a quantitative amount of culture medium is poured into the culture bottle under the action of gravity.

[0004] Existing automatic bottle filling devices for king oyster mushroom culture media require stopping the equipment and using auxiliary tools to remove and replace the metering valve when filling culture bottles of different volumes. The installation process also requires precise operation to ensure that the metering valve is installed firmly and in the correct position; otherwise, it will affect the subsequent filling accuracy. The entire process of replacing the metering valve is not only labor-intensive but also seriously reduces production efficiency. Therefore, we propose an automatic bottle filling device for king oyster mushroom culture media. Utility Model Content

[0015] The motor drives the rotating shaft to rotate, and the gear meshes with the gear ring, causing the rotating column to rotate. When the feeding trough aligns with the guide plate, the culture medium falls into the feeding trough, achieving material collection. As the rotating column rotates, when the opening of the feeding trough faces downwards, the culture medium is poured into the culture bottle through the outlet of the guide box. When dealing with culture bottles of different volumes, rotating the knob drives the lead screw to rotate, and the adjusting plate slides up and down under the limit guidance of the guide groove, thereby adjusting the volume of the feeding trough and achieving quantitative feeding of the culture medium. The volume of the feeding trough can be easily adjusted without complicated disassembly procedures. Operators can quickly complete the adjustment, significantly reducing the difficulty of operation, reducing equipment downtime, increasing the filling volume of the automatic bottle filling device at the same time, and effectively improving the filling efficiency of the culture medium.

[0022] The technical solutions of the present utility model will be clearly and completely described below with reference to the accompanying drawings of the embodiments. Obviously, the described embodiments are only some embodiments of the present utility model, and not all embodiments. Based on the embodiments of the present utility model, all other embodiments obtained by those of ordinary skill in the art without creative effort are within the protection scope of the present utility model.

[0023] Please see Figure 1-5This embodiment provides a technical solution: an automatic bottle-filling device for king oyster mushroom culture medium, including a support 1, a storage tank 2 located in the middle of the upper surface of the support 1, a cover plate hinged to the top of the storage tank 2, and a feeding mechanism 6. A microcontroller 11 is located outside the support 1, with its input terminal electrically connected to an external power source. A support frame 3 is located at the bottom of the support 1, with drive rollers 4 rotatably connected to the front and rear inner walls of the support frame 3. A conveyor belt 5 is connected between the leftmost and rightmost drive rollers 4. The outer arc surfaces of the remaining drive rollers 4 in the middle contact the inner wall of the conveyor belt 5, providing auxiliary support for the conveyor belt 5. (The conveyor belt 5 will not collapse when carrying culture flasks). A motor 10 is located on the front side of the support frame 3. The rear end of the output shaft of motor 10 is fixedly connected to the front end of the leftmost transmission roller 4. The input end of motor 10 is electrically connected to the output end of microcontroller 11. A rotating rod 7 is rotatably connected to the top wall of the storage tank 2. Evenly distributed stirring rods 8 are located on the outside of the rotating rod 7. A motor 9 is located on the upper surface of the storage tank 2. The bottom end of the output shaft of motor 9 is fixedly connected to the top end of the rotating rod 7. The input end of motor 9 is electrically connected to the output end of microcontroller 11. A photoelectric sensor 12 is located on the front side of the rear crossbeam of the bracket 1. The photoelectric sensor 12 is connected to the microcontroller 11. The photoelectric sensor 12 is a diffuse-reflective type photoelectric sensor. The detection head of the photoelectric sensor 12 also contains a light emitter and a light receiver, but there is no reflector in front. Under normal circumstances, the light emitted by the light emitter of the photoelectric sensor 12 cannot be detected by the light receiver at a specified distance. When the culture bottle moves to a position corresponding to the front and back of the photoelectric sensor 12, it blocks the light and partially reflects it back. The light receiver of the photoelectric sensor 12 then receives the light signal and outputs a switching signal. When the king oyster mushroom culture medium needs to be bottled, first open the hinged cover at the top of the storage tank 2, pour the mixed culture medium into it, and then control the microcontroller... With the control of the microcontroller 11, motor 29 starts to run, and the output shaft drives the rotating rod 7 to rotate, which in turn drives the stirring rod 8 to stir the culture medium in the storage tank 2 to prevent the culture medium from settling or clumping. Then, the cleaned and disinfected bottles are placed on the conveyor belt 5. With the control of the microcontroller 11, motor 310 drives the transmission roller 4 to rotate, and the conveyor belt 5 transports the culture bottles to the bottom of the feeding mechanism 6. When the culture bottle reaches the designated position, the photoelectric sensor 12 detects the signal and sends a control switch signal back to the microcontroller 11. After filling is completed, the conveyor belt 5 continues to run and sends out the culture bottle. At the same time, the next empty bottle enters the filling position to realize continuous automated production.

[0024] The feeding mechanism 6 includes a guide box 61, a guide plate 62, a rotating column 63, and a feeding trough 64. The bottom end of the storage tank 2 is fixedly connected to the guide box 61, and the interior of the storage tank 2 is connected to the interior of the guide box 61. The bottom end of the guide box 61 is provided with a discharge port. The rotating column 63 is rotatably connected between the front and rear inner walls of the guide box 61. The outside of the rotating column 63 is provided with a feeding trough 64. The left and right ends of the front and rear inner walls of the guide box 61 are respectively provided with guide plates 62. The guide plates 62 are installed in conjunction with the feeding trough 64 (the guide plates 62 are inclined from the left and right sides towards the rotating column 63). The feeding mechanism 6 also includes a guide groove 65, an adjusting plate 66, a lead screw 67, and a bellows 68. The left and right inner walls of the feeding trough 64 are respectively provided with guide grooves 65. An adjusting plate 66 is slidably connected between the guide groove 65 and the guide groove 65. A lead screw 67 is rotatably connected between the bottom wall of the guide box 61 and the top wall of the rotating column 63. The front end of the adjusting plate 66 is threadedly connected to the lead screw 67. Corrugated pipes 68 are respectively provided between the upper side of the adjusting plate 66 and the top wall of the rotating column 63, and between the lower side of the adjusting plate 66 and the bottom wall of the guide box 61. The lead screw 67 is located inside the corrugated pipes 68. A knob is fixedly connected to the end of the lead screw 67 that extends to the outside of the rotating column 63. (Rubber pads can be provided on the front, back, left, and right sides of the adjusting plate 66 and the inner wall of the guide groove 65 to ensure the sealing when the position of the adjusting plate 66 is adjusted). The feeding mechanism 6 also includes a drive assembly 69, which includes a gear ring 691, a rotating shaft 692, and a gear 69. 3. A gear ring 691 is fixedly sleeved on the outer rear end of the rotating column 63. A rotating shaft 692 is rotatably connected to the rear side of the guide box 61. A gear 693 is fixedly sleeved on the outer side of the rotating shaft 692. The gear ring 691 meshes with the gear 693. A protective cover is provided on the rear side of the guide box 61. The gear ring 691 and the gear 693 are both located inside the protective cover. A motor 694 is located on the rear side of the protective cover. The front end of the output shaft of the motor 694 is fixedly connected to the rear end of the rotating shaft 692. The input end of the motor 694 is electrically connected to the output end of the microcontroller 11. The bottom of the storage tank 2 is connected to the guide box 61. The stirred culture medium flows into the guide box 61 under the action of gravity. The microcontroller 11 will control the motor 694 to start, and the output shaft will drive the motor 694 to start. Rotating shaft 692 causes gear 693 to mesh with gear ring 691, causing rotating column 63 to rotate. The feeding trough 64 outside rotating column 63 rotates with rotating column. When feeding trough 64 is aligned with guide plate 62, culture medium falls from storage tank 2 into feeding trough 64, realizing material retrieval. As rotating column 63 rotates, when the opening of feeding trough 64 faces downward, culture medium will be poured into the culture bottle through the outlet of guide box 61 under the action of gravity. When facing culture bottles of different volumes, rotating knob drives screw 67 to rotate. Adjusting plate 66 slides up and down under the limiting guidance of guide groove 65 to adjust the volume of feeding trough 64, thereby controlling the amount of culture medium dispensed each time. Bellows 68 can prevent material from entering screw mechanism and ensure adjustment accuracy.

[0025] The working principle of the automatic bottling device for king oyster mushroom culture medium provided by this utility model is as follows: When the king oyster mushroom culture medium needs to be bottled, firstly, open the cover plate at the top of the storage tank 2, which is hinged, and pour the mixed culture medium into it. Under the control of the microcontroller 11, the motor 9 starts to run, and the output shaft drives the rotating rod 7 to rotate, which drives the stirring rod 8 to stir the culture medium in the storage tank 2 to prevent the culture medium from settling or clumping. The bottom of the storage tank 2 is connected to the guide box 61. The stirred culture medium flows into the guide box 61 under the action of gravity. Then, the cleaned and disinfected bottles are placed on the conveyor belt 5. Under the control of the microcontroller 11, the motor 10 drives the leftmost transmission roller 4 to rotate. With the cooperation of the rightmost transmission roller 4, the conveyor belt 5 carries the culture medium... The bottles are conveyed to the bottom of the feeding mechanism 6. When the culture bottles reach the designated position, the photoelectric sensor 12 detects a signal and sends a control switch signal to the microcontroller 11. The microcontroller 11 starts the control motor 694, and the output shaft drives the rotating shaft 692 to rotate. The gear 693 meshes with the gear ring 691, causing the rotating column 63 to rotate. The feeding trough 64 outside the rotating column 63 rotates with the rotating column. (The two guide plates 62 and the guide box 61 form a cavity as a flow channel. The upper end of the feeding trough 64 and the flow channel can be completely misaligned, partially misaligned, or completely aligned, corresponding to three situations. When completely misaligned, the lower edges of both guide plates 62 are tangentially in contact with the rotating column 63. When partially misaligned, the lower edge of one guide plate 62 is tangentially in contact with the rotating column 63, and the lower edge of the other guide plate 62 is tangentially in contact with the rotating column 63.) The lower edge of the guide plate 62 is located on the upper side of the feeding trough 64. When they are fully aligned, the lower edges of the two guide plates 62 are located at the upper edges of the feeding trough 64 (the feeding trough 64 is directly opposite the flow channel). As the upper end of the feeding trough 64 and the flow channel move from partial misalignment to full alignment, and as the upper end of the feeding trough 64 and the flow channel move from partial misalignment to full misalignment, the culture medium falls from the storage tank 2 into the feeding trough 64 until the feeding trough 64 is full, thus achieving material removal. (Excess culture medium will remain in the flow channel because the lower edges of both guide plates 62 are in tangential contact with the rotating column 63. As the rotating column 63 rotates, its outer arc surface blocks the flow channel.) As the rotating column 63 rotates, when the opening of the feeding trough 64 faces downwards, the culture medium will be released under the influence of gravity. The culture medium is poured into the culture bottle through the outlet of the guide box 61. When dealing with culture bottles of different volumes, the screw 67 is rotated by rotating the knob. (An observation window with scale lines can be set at the front end of the rotating column 63. The depth of the adjusting plate 66 is determined by comparing it with the scale lines.) The adjusting plate 66 slides up and down under the limiting guidance of the guide groove 65, adjusting the volume of the feeding groove 64. (The length and width of the feeding groove 64 remain constant. The volume of the feeding groove 64 can be adjusted by adjusting the depth of the adjusting plate 66, i.e., the height of the feeding groove 64.) This controls the amount of culture medium dispensed each time. The corrugated pipe 68 prevents material from entering the screw mechanism, ensuring adjustment accuracy. After filling, the conveyor belt 5 continues to run, sending the culture bottle out.Meanwhile, the next empty bottle enters the filling station, achieving continuous automated production.

[0026] It is worth noting that the microcontroller 11 disclosed in the above embodiments can be an LPC54102, the motor 694 can be an RS555, the motor 9 can be a YS8024, the motor 10 can be a Y180L-615, and the photoelectric sensor 12 can be an EW-D61 photoelectric sensor. The microcontroller 11 controls the operation of the motor 694, the motor 9, the motor 10 and the photoelectric sensor 12 using methods commonly used in the prior art.
