Description

Technical Field

[0001] This utility model relates to the field of black fungus spawn production technology, specifically to a black fungus spawn opening device. Background Technology

[0002] Opening the spawn logs is a crucial step in the cultivation of black fungus, directly affecting its growth, yield, and quality. Opening the logs creates favorable conditions for black fungus growth, regulates oxygen and moisture within the logs, promotes mycelial growth and fruiting body formation, and ultimately improves the yield and quality of black fungus, which is of great significance to the profitability of cultivation.

[0003] For example, a black fungus spawn opening device with authorization announcement number "CN220292699U" uses a spiked wheel at the rear end of a swing arm to open the spawn, facilitating the growth of black fungus. The swing arm, pulled by a return spring, can open spawns of different thicknesses, increasing the device's adaptability. Traditional black fungus spawn opening devices rely on manual handling and loading, requiring workers to repeatedly bend over, lift, and place spawns, easily causing physical fatigue and increasing labor intensity. Furthermore, this device relies on the spiked wheel and return spring at the rear end of the swing arm for opening. The pressure of the spiked wheel on the spawn can vary due to changes in the elasticity of the return spring and differences in the consistency of the swing arm's movement, making it difficult to guarantee uniform penetration depth and force, resulting in uneven opening depth and size, affecting the consistency of black fungus fruiting. Utility Model Content

[0004] The purpose of this invention is to solve the problems of traditional black fungus spawn opening devices, which require manual handling and feeding of spawn logs one by one, necessitating repeated bending, lifting, and placing of spawn logs, increasing the labor intensity of workers, and the uneven force on the spawn logs during opening, causing them to shake and resulting in uneven opening depth and size, thus affecting the consistency of black fungus fruiting. Therefore, this invention proposes a black fungus spawn opening device.

[0005] To achieve the above objectives, this utility model provides the following technical solution:

[0006] A black fungus spawn opening device is designed, comprising a base and a vertical plate. The vertical plate is fixedly connected to the upper rear side of the base, and a first shell is fixedly connected to the front right side of the vertical plate. The interior of the first shell is provided with a black fungus spawn opening structure. The outer wall of the front left side of the vertical plate is provided with a black fungus spawn feeding structure. A block is fixedly connected to the upper front side of the base.

[0007] Preferably, the opening structure of the black fungus spawn includes a first servo motor, the outer wall of which is fixedly connected to a first housing, and a threaded rod fixedly connected to the output shaft of the first servo motor. Both ends of the threaded rod are rotatably connected to the first housing via bearings. The outer wall of the threaded rod is threadedly connected to a threaded block. Both ends of the threaded block are fixedly connected to a crossbar. The lower end of the crossbar is fixedly connected to a protruding rod. The outer wall of the protruding rod is fixedly connected to the first housing. Both sides of the lower end of the protruding rod are fixedly connected to a second housing. A spring is provided inside the second housing. Both ends of the spring are fixedly connected to the second housing and a limiting plate, respectively. The outer wall of the limiting plate is slidably connected to the second housing.

[0008] Preferably, the inner wall of the crossbar is slidably connected to the slide bar, both ends of the slide bar are fixedly connected to the first housing, and the inner end of the second housing is fixedly connected with a spike.

[0009] Preferably, the black fungus spawn feeding structure includes a third shell and a second servo motor. The outer wall of the third shell is fixedly connected to a vertical plate. The upper left side of the third shell is fixedly connected to the feed inlet. A semi-circular ring is fixedly connected to the lower end of the third shell. The outer wall of the second servo motor is fixedly connected to the vertical plate. The output shaft of the second servo motor is rotatably connected to the vertical plate through a bearing. A disc is fixedly connected to the output shaft of the second servo motor. Multiple grooves are formed on the outer wall of the disc.

[0010] Preferably, a conveyor belt is installed between the block and the vertical plate, and a third servo motor is fixedly connected to the outer wall of the left block.

[0011] Preferably, the output shaft of the third servo motor is connected to the conveyor belt, and multiple semi-cylinders are installed on the outer wall of the conveyor belt.

[0012] The beneficial effects of the black fungus spawn opening device proposed in this utility model are as follows: through the cooperation of the black fungus spawn feeding structure and the vertical plate, the output shaft of the second servo motor rotates to drive the disc to rotate. The rotation of the disc drives the black fungus spawn in the groove to move. Since the disc is filled with black fungus spawn, a kind of enclosed space is formed, so that the black fungus spawn in the groove will not fall out due to rotation. When the black fungus spawn in the groove moves to the semi-circular ring, the gap between the semi-circular ring and the groove is only one-tenth of the diameter of the black fungus spawn, so the black fungus spawn in the groove will not fall out during rotation. When the black fungus spawn in the groove rotates out of the range of the semi-circular ring, the black fungus spawn in the groove will fall between the two semi-cylinders on the conveyor belt, thus automatically feeding the black fungus spawn.

[0013] Through the cooperation of the black fungus spawn opening structure and the first shell, the output shaft of the first servo motor rotates, driving the threaded rod to rotate. The rotation of the threaded rod drives the threaded block to move. The movement of the threaded block drives the crossbar to slide downward on the slide bar. The slide bar acts as a limiter, preventing the threaded block from rotating with the rotation of the threaded rod. The movement of the crossbar drives the convex rod to move. The movement of the convex rod drives the second shell to move. The movement of the second shell drives the limiting plate to move downward. When the limiting plate contacts the black fungus spawn, the limiting plate will compress the spring and slide upward in the second shell. At this time, the spike moves downward to open the black fungus spawn. The contact between the limiting plate and the black fungus spawn fixes the black fungus spawn, avoiding uneven force on the black fungus spawn and causing shaking, thus improving the consistency of black fungus fruiting.

[0023] The present invention will be further described below with reference to the accompanying drawings:

[0024] See attached document Figure 1-8 In this embodiment, a black fungus spawn opening device includes a base 1 and a vertical plate 2. The vertical plate 2 is fixedly connected to the upper rear side of the base 1. The first shell 3 is fixedly connected to the front right side of the vertical plate 2. The interior of the first shell 3 is provided with a black fungus spawn opening structure 4. The outer wall of the front left side of the vertical plate 2 is provided with a black fungus spawn feeding structure 7. The upper front side of the base 1 is fixedly connected with a block 8. The inner wall of the crossbar 404 is slidably connected to the slide bar 5. The crossbar 404 slides on the slide bar 5.

[0025] Both ends of the slide bar 5 are fixedly connected to the first housing 3. The slide bar 5 serves as a limit to prevent the threaded block 403 from rotating with the threaded rod 402. The inner end of the second housing 406 is fixedly connected to a spike 6. A conveyor belt 10 is installed between the block 8 and the vertical plate 2. The conveyor belt 10 consists of two toothed pulleys and a toothed belt. The outer wall of the left block 8 is fixedly connected to a third servo motor 9. The output shaft of the third servo motor 9 is connected to the conveyor belt 10. The output shaft of the third servo motor 9 is fixedly connected to the toothed pulley on the left. Multiple semi-cylinders 11 are installed on the outer wall of the conveyor belt 10. The semi-cylinders 11 are made of rubber.

[0026] See attached document Figure 1 , Figure 2 , Figure 3 and Figure 5 The black fungus spawn opening structure 4 includes a first servo motor 401. The outer wall of the first servo motor 401 is fixedly connected to the first housing 3. The output shaft of the first servo motor 401 is fixedly connected to a threaded rod 402. Both ends of the threaded rod 402 are rotatably connected to the first housing 3 through bearings. The threaded rod 402 rotates inside the first housing 3 through the bearings. The outer wall of the threaded rod 402 is threadedly connected to a threaded block 403. The rotation of the threaded rod 402 drives the threaded block 403 to move.

[0027] Both ends of the threaded block 403 are fixedly connected to a crossbar 404. The lower end of the crossbar 404 is fixedly connected to a protruding rod 405. The outer wall of the protruding rod 405 is fixedly connected to the first housing 3. Both sides of the lower end of the protruding rod 405 are fixedly connected to a second housing 406.

The model of the spring 407 is selected according to actual needs, as long as it meets the working requirements. The outer wall of the limiting plate 408 is slidably connected to the second housing 406.

[0028] The limiting plate 408 slides within the second housing 406.

[0029] See attached document Figure 1 , Figure 2 , Figure 6 and Figure 8The black fungus spawn feeding structure 7 includes a third shell 701 and a second servo motor 704. The outer wall of the third shell 701 is fixedly connected to the vertical plate 2. The upper left side of the third shell 701 is fixedly connected to the feed inlet 702. A box cover is installed at the upper end of the feed inlet 702. A rubber pad is installed at the position where the feed inlet 702 contacts the box cover to fill the gap between the feed inlet 702 and the box cover.

[0030] A semi-circular ring 703 is fixedly connected to the lower end of the third housing 701. The outer wall of the second servo motor 704 is fixedly connected to the vertical plate 2. The output shaft of the second servo motor 704 is rotatably connected to the vertical plate 2 through a bearing. The second servo motor 704 rotates inside the vertical plate 2 through the bearing. A disc 705 is fixedly connected to the output shaft of the second servo motor 704. Multiple grooves 706 are provided on the outer wall of the disc 705.

[0031] Working principle:

[0032] When using the black fungus spawn opening device:

[0033] Feeding:

[0034] Place the collection box containing the black fungus spawn at the inlet 702, remove the cover of the inlet 702, and place the black fungus spawn horizontally through the inlet 702 into the third shell 701 (e.g., Figure 8 The black fungus spawn log slides down into the groove 706 of the disc 705 due to gravity. To further clarify, the front-to-back length of the black fungus spawn log is consistent with the front-to-back inner wall dimensions of the third shell 701, ensuring the black fungus spawn log does not tilt when inside the third shell 701. The groove of the disc 705 matches the dimensions of the black fungus spawn log. The external power supply to the second servo motor 704 is connected, and the second servo motor 704 is started. The external power supply to the third servo motor 9 is connected, and the third servo motor 9 is started. The conveyor belt 10 begins operation, and the output shaft of the second servo motor 704 rotates, causing the disc 705 to rotate (e.g., ...). Figure 6The rotation of disc 705 causes the black fungus spawn in groove 706 to move. Because the disc 705 is covered with black fungus spawn, it forms a near-closed space, preventing the spawn from falling out of groove 706 during rotation. When the spawn in groove 706 moves to semi-circular ring 703, the gap between semi-circular ring 703 and groove 706 is only one-tenth the diameter of the spawn, again preventing the spawn from falling out during rotation. When the spawn in groove 706 rotates out of the semi-circular ring 703, groove 706... The black fungus spawn will fall between the two semi-cylinders 11 on the conveyor belt 10 (even if it does not fall precisely, the black fungus spawn will slide between the two semi-cylinders 11 due to gravity when it falls on the two adjacent semi-cylinders 11, which means that it is not absolutely precise and there is a certain margin of error, but it can still ensure that the black fungus spawn is stuck between the two semi-cylinders 11). The rotation speeds of the second servo motor 704 and the third servo motor 9 work together to ensure that each black fungus spawn falls between the two semi-cylinders 11. The semi-cylinders 11 limit the black fungus spawn and prevent it from rolling out of the conveyor belt 10.

[0035] Opening of the black fungus spawn:

[0036] The conveyor belt 10 moves the black fungus spawn sticks above to the right. (When transporting a large number of black fungus spawn sticks, auxiliary wheels can be added to the conveyor belt 10 to prevent the conveyor belt from collapsing.) When it moves to below the spikes, the conveyor belt 10 is controlled by a servo motor. The servo motor controls the rotation time through pulse frequency and the rotation distance through the number of pulses. By calculating the time of the black fungus spawn stick opening structure 4 descending-opening-rising in actual production, the servo motor rotation time is controlled by pulse frequency so that the black fungus spawn stick opening structure 4 completes one cycle (descending-opening-rising). Then the conveyor belt 10 can transport the next black fungus spawn stick directly below the black fungus spawn stick opening structure 4.

[0037] When the external power supply of the first servo motor 401 is connected and the first servo motor 401 is started, the output shaft of the first servo motor 401 rotates, driving the threaded rod 402 to rotate (e.g. Figure 3The rotation of the threaded rod 402 causes the threaded block 403 to move. The movement of the threaded block 403 causes the crossbar 404 to slide downward on the slide bar 5. The slide bar 5 acts as a limit to prevent the threaded block 403 from rotating with the rotation of the threaded rod 402. The movement of the crossbar 404 causes the protruding rod 405 to move. The movement of the protruding rod 405 causes the second housing 406 to move. The movement of the second housing 406 causes the limiting plate 408 to move downward. When the limiting plate 408 contacts the black fungus stick, the limiting plate 408 will compress the spring 407 and slide upward relative to it within the second housing 406. At this time, the spike 6 continues to move downward to open the black fungus stick. To further explain, the lower end of the limiting plate 408 is arc-shaped. The black fungus stick is between two semi-cylinders 11. The semi-cylinders 11 act as a limit to the black fungus stick. The upper limiting plate 408 presses the black fungus stick tightly, thereby avoiding uneven force on the black fungus stick and causing it to shake.

[0038] The phenomenon of movement improves the consistency of black fungus growth. The output shaft of the first servo motor 401 reverses. The first servo motor 401 resets the spike 6 through the above connection method, which facilitates the opening of the next black fungus stick. When the black fungus stick after opening moves to the right end of the transmission belt 10, the operator places the black fungus stick after opening into the storage bucket. Repeat the above operation to complete the working process of the black fungus stick opening device.
