A quick-connect cover assembly 2 that is quickly connected to the inoculation tube 11 is provided on the outside of the inoculation tube 11 to ensure that the opening of the inoculation tube 11 can be quickly closed and sealed after sampling or adding liquid in the fermentation tank 1. A plurality of opening assemblies are provided in the quick-connect cover assembly 2, and the opening assemblies are used to expose the opening of the inoculation tube 11 between the quick-connect cover assembly 2 and the inoculation tube 11 without removing it, ensuring that a continuous quick-connect structure is maintained between the quick-connect cover assembly 2 and the inoculation tube 11. A stabilizing assembly 3 is provided between the quick-connect cover assembly 2 and the plurality of opening assemblies, and the stabilizing assembly 3 is used to control the plurality of opening cavities The components move synchronously, so that the size of the internal opening of the quick-connect cover assembly 2 is adjusted synchronously. The interior of the quick-connect cover assembly 2 is provided with a debris removal assembly 5 that cooperates with the cavity assembly, and the debris removal assembly 5 is used to clean one side of the cavity assembly during movement to ensure that the quick-connect cover assembly 2 maintains a good sealing effect; and the number of the cavity assemblies is five groups, and the five groups of cavity assemblies are arranged in a surrounding array at the top of the first quick-connect cover 21, so that the five groups of cavity assemblies can be opened or closed during the simultaneous movement, and the plug 12 can be inserted into the interior of the material trough 24 opened in the second quick-connect cover 22, which can reduce the exposure range of the sealing plate 25 in the material trough 24.

[0041] refer to Figure 2 、 Figure 3 、 Figure 4 and Figure 5 As shown, the quick-connect cover assembly 2 includes a first quick-connect cover 21 screwed onto the outside of the inoculation tube 11 and a second quick-connect cover 22 installed on the top of the first quick-connect cover 21, and an adjusting bolt 23 is commonly connected between the second quick-connect cover 22 and the first quick-connect cover 21, and the adjusting bolt 23 is used to keep the first quick-connect cover 21 and the second quick-connect cover 22 disassembled or fixed, and a material trough 24 communicating with the inside of the inoculation tube 11 is commonly provided between the second quick-connect cover 22 and the first quick-connect cover 21, and a stabilizing component 3 is provided between the first quick-connect cover 21 and the inoculation tube 11, and the stabilizing component 3 is used to keep the material trough 24 and the opening of the inoculation tube 11 positioned and coincident after the first quick-connect cover 21 is installed on the outside of the inoculation tube 11; the stabilizing component 3 The screw threaded frame 31 is fixedly sleeved on the top of the inoculation tube 11 and the screw threaded ring 32 is screwed on the bottom end of the first quick-connect cover 21. The outside of the screw threaded frame 31 is threadedly connected to the inside of the first quick-connect cover 21. The bottom end of the first quick-connect cover 21 is provided with a screw groove 34 for the screw threaded ring 32 to be screwed. The inside of the screw threaded ring 32 is fixedly connected with an inclined arc pushing plate 35. A flexible pressure plate 33 is installed on the side of the screw threaded ring 32 close to the arc pushing plate 35, and there is a gap between the flexible pressure plate 33 and the screw threaded ring 32. When the screw threaded ring 32 moves, one side of the arc pushing plate 35 contacts the outside of the flexible pressure plate 33 and pushes the flexible pressure plate 33 toward the outside of the inoculation tube 11 for locking, so that the first quick-connect cover 21 and the inoculation tube 11 can maintain a stable connection.

[0042] refer to Figure 2 、 Figure 3 、 Figure 4 and Figure 5 As shown, the second quick-connect cover 22, the first quick-connect cover 21 and the cavity assembly are combined to form a quick-connect sealing cover. At this time, the second quick-connect cover 22, the first quick-connect cover 21, the inoculation tube 11 and the cavity assembly are combined to form a semi-disassembled structure, and the flexible pressure plate 33 itself has elasticity, so that after the arc-pushing plate 35 conflicts with the flexible pressure plate 33, the flexible pressure plate 33 itself elastically deforms, so that the flexible pressure plate 33 approaches the outside of the inoculation tube 11, ensuring that the flexible pressure plate 33 and the inoculation tube 11 are in tight contact. In addition, the stabilizing component 3 is used to maintain a positioning quick connection between the first quick-connect cover 21 and the inoculation tube 11. During multiple connection and disassembly processes, due to accurate positioning, forced friction and collision between the two are avoided, wear and damage to the connecting components are reduced, and the service life of the sealing cover and the inoculation tube 11 is extended. At the same time, the positioning quick connection design makes the connection and separation operations between the sealing cover and the inoculation tube 11 very fast, reducing the difficulty of operation.

[0043] refer to Figure 2 、 Figure 3 、 Figure 4 and Figure 5As shown; when it is necessary to quickly connect the first quick-connect cover 21 and the inoculation tube 11, first rotate the adjusting bolt 23 to screw the second quick-connect cover 22 to the first quick-connect cover 21 to ensure that the second quick-connect cover 22 and the first quick-connect cover 21 maintain good stability, and then rotate the first quick-connect cover 21 to drive the flexible pressure plate 33 to move downward along the outside of the inoculation tube 11. At this time, part of the first quick-connect cover 21 is inserted into the interior of the threaded frame 31, and the first quick-connect cover 21 is screwed to the inside of the threaded frame 31. The interior of the quick-connect cover 21 is screwed to the threaded frame 31, and the top of the threaded frame 31 contacts the interior of the first quick-connect cover 21. The first quick-connect cover 21 can no longer be rotated, so that the first quick-connect cover 21 is screwed to the inoculation tube 11, and the material trough 24 and the inoculation tube 11 are kept overlapped. The threaded ring 32 is rotated to keep it in a screw connection with the threaded groove 34 opened at the bottom end of the first quick-connect cover 21. The rotation of the threaded ring 32 drives the arc push plate 35 to rotate synchronously, so that the arc push plate 35 One side passes through the gap between the flexible pressure plate 33 and the threaded ring 32. As one side of the arc pushing plate 35 forms a slope with the outside of the flexible pressure plate 33, the arc pushing plate 35 and the flexible pressure plate 33 are in contact and push the flexible pressure plate 33 toward the outside of the inoculation tube 11. Then, the flexible pressure plate 33 and the inoculation tube 11 are in close contact, so that the first quick-connect cover 21 and the inoculation tube 11 maintain a stable locking state, so that the first quick-connect cover 21, the inoculation tube 11 and the threaded frame 31 form a mechanical interlocking, which can The pressing force between the first quick-connect cover 21 and the inoculation tube 11 is supplemented to reduce the gap, enhance the stability of the connection, ensure a good sealing effect between the sealing cover and the inoculation tube 11, and facilitate the quick connection between the first quick-connect cover 21 and the inoculation tube 11. When sampling or adding liquid inside the fermentation tank 1, there is no need to frequently disassemble and assemble the first quick-connect cover 21 on the inoculation tube 11. It is only necessary to open the cavity assembly inside the first quick-connect cover 21 to complete the operation, which reduces the operation time and thus improves the flexibility of the quick-connect use of the quick-connect sealing cover.

[0044] refer to Figure 6 and Figure 7As shown, the cavity opening assembly includes a sealing plate 25 movably connected between the first quick-connect cover 21 and the second quick-connect cover 22 and a fixed seat 26 slidably connected to the top of the first quick-connect cover 21, and the sealing plate 25 is used to realize the sealing closure of the feed trough 24 and the inoculation tube 11. The first quick-connect cover 21 is fixedly connected to a connecting shaft column 201 on one side close to the feed trough 24, and the sealing plate 25 is sleeved on the outside of the connecting shaft column 201. The connecting shaft column 201 is used to move the sealing plate 25 along its outer circumference. The bottom end of the fixed seat 26 is installed with a connecting shaft column 27, and the bottom of the connecting shaft column 27 is sleeved with an arc-shaped moving arm 28. The moving arm 28 A crank arm 29 is commonly connected to the sealing plate 25; the moving assembly 4 includes a middle support ring 41 rotatably connected between the second quick-connect cover 22 and the first quick-connect cover 21, and a mounting plate 44 fixedly connected to the outside of the second quick-connect cover 22. The bottom end of the mounting plate 44 is fixedly connected to a servo motor 43. A ring gear 42 is fixedly sleeved on the outside of the middle support ring 41. A gear 45 meshing with the ring gear 42 is installed at the output end of the servo motor 43. A limiting groove 203 is formed at the top of the middle support ring 41. A limiting column 202 is installed at the end of the second quick-connect cover 22 near the middle support ring 41, and the limiting column 202 is slidably connected to the inside of the limiting groove 203.

[0045] The sealing plate 25 is in a petal-shaped structure, which can maximize the sealing contact area within a limited space, ensuring a good sealing effect on the inoculation tube 11;

[0046] refer to Figure 6 and Figure 7As shown, when the first quick-connect cover 21 is connected to the inoculation tube 11, there is no need to frequently disconnect and disconnect to realize sampling or adding liquid inside the fermentation tank 1, and the servo motor 43 drives the gear 45 to move synchronously, and then the gear 45 rotates and engages with the gear ring 42 to drive the middle ring 41 to realize circular motion between the second quick-connect cover 22 and the first quick-connect cover 21. At this time, the rotation of the middle ring 41 drives the fixed seat 26 to move synchronously, and the rotation of the middle ring 41 drives the position of the limiting groove 203 to move synchronously, and then the inside of the limiting groove 203 and the outside of the limiting column 202 keep moving, and the limiting groove 203 and the limiting column 202 keep moving. The control column 202 is used to guide the centering ring 41 during the rotation process, and moves along the top circumference of the first quick-connect cover 21 through the fixed seat 26. Then the fixed seat 26 rotates to drive the connecting shaft column 27 to rotate synchronously. At this time, the movement of the connecting shaft column 27 drives the moving arm 28 and the curved arm 29 to move synchronously. The curved arm 29 moves to pull the sealing plate 25, so that the sealing plate 25 is close to the curved arm 29 to form a pulling force to pull the sealing plate 25 to move. In addition, the sealing plate 25 moves along the outer circumference of the connecting shaft column 201, so that the sealing plate 25 moves along the outer circumference of the first quick-connect cover 21 under the action of the connecting shaft column 201. 1 is rotated and adjusted, so that the sealing plate 25 slowly approaches the outside of the fixed seat 26 when it rotates, and the sealing plate 25 pushes the curved arm 29 and the movable arm 28 during the movement, so that a suitable distance is formed between the movable arm 28 and the sealing plate 25 to prevent mutual interference, and the movable arm 28 swings along the outside of the connecting shaft column 27 during the movement, so that the angle of the movable arm 28 is adjusted with the fixed seat 26, so that the sealing plate 25 slides out along the opening of the inoculation tube 11 and the feed trough 24 when it rotates, and then the inoculation tube 11 and the feed trough 24 are exposed. Then, sampling or liquid addition operations can be carried out inside the fermentation tank 1 without completely removing the entire sealing cover from the outside of the inoculation tube 11. Sampling or liquid addition operations can be carried out inside the fermentation tank 1, and then it is only necessary to open and close the first quick-connect cover 21, which can better maintain the integrity of the seal and improve the sealing integrity of the quick-connect sealing cover. At the same time, the expansion angle of the sealing plate 25 can be flexibly adjusted to achieve precise control of the size of the inoculation port of the inoculation tube 11, which can not only ensure the smooth progress of inoculation, but also quickly restore the good sealing state after inoculation, thereby improving the reliability of the sealing cover.

[0047] refer to Figure 6 、 Figure 7 、 Figure 8 、 Figure 9 and Figure 10As shown, the debris removal assembly 5 includes a debris removal groove 53 provided at the top of the first quick-connect cover 21 and a debris removal roller 51 installed in the debris removal groove 53, and the outer portion of the debris removal roller 51 is in contact with the bottom of the sealing plate 25. A support frame 52 is commonly connected between the debris removal roller 51 and the debris removal groove 53, and the support frame 52 is used for the debris removal roller 51 to rotate along the interior thereof. A rotating column 502 is commonly connected between the support frame 52 and the debris removal groove 53, and a co-directional component is provided between the debris removal roller 51 and the support frame 52.

[0048] When the sealing plate 25 moves along the top of the first quick-connect cover 21, the sealing plate 25 slides over the first quick-connect cover 21 and approaches the impurity removal groove 53 through the movement of the sealing plate 25. At this time, the bottom of the sealing plate 25 is located above the impurity removal groove 53 and the bottom of the sealing plate 25 and the impurity removal roller cloth 51 remain tilted and staggered, and the contact area between the sealing plate 25 and the impurity removal roller cloth 51 gradually increases; the oblique contact increases the effective contact area and friction between the sealing plate 25 and the impurity removal roller cloth 51, and can utilize the combined force of gravity and friction generated between each other, which is conducive to reducing the medium residue at the bottom of the sealing plate 25, so as to ensure the cleanliness of the sealing plate 25. As the contact area between the sealing plate 25 and the impurity removal roller cloth 51 increases, the impurity removal roller cloth 51 can cover a larger surface area of ​​the sealing plate 25, effectively remove more impurities hidden in different positions, and reduce impurity residues, thereby ensuring the cleanliness of the sealing cover so that the sealing cover can achieve a good sealing effect when closed.

[0050] refer to Figure 8 、 Figure 9、 Figure 10 、 Figure 11 and Figure 12 As shown, a step is formed between two adjacent thorn blocks 501. When the baffle 59 moves counterclockwise along the top of one of the thorn blocks 501, the baffle 59 moves along the top of one of the thorn blocks 501 toward the other thorn block 501. At this time, the baffle 59 moves from top to bottom along the top of the other thorn block 501, and then the baffle 59 moves along the top of the other thorn block 501 toward the vicinity of one of the thorn blocks 501. At this time, the baffle 59 moves to the junction of the two thorn blocks 501. After that, the bottom of the baffle 59 comes into contact with one of the thorn blocks 501 at the top of another thorn block 501. At this time, the baffle 59 cannot continue to move along the top of the thorn block 501, which is used to limit the movement direction of the baffle 59 along the thorn block 501, so that the concentric disk 55 rotates in one direction along the centering ring 56, preventing the debris removal roller 51 from moving back and forth with the sealing plate 25 after contacting the sealing plate 25, ensuring that the debris removal roller 51 can stably clean the sealing plate 25 and optimize the cleaning path;

[0051] refer to Figure 8 、 Figure 9 、 Figure 10 、 Figure 11 and Figure 12 As shown, when the baffle 59 moves clockwise along the top of one of the thorn blocks 501, the baffle 59 moves along the top of one of the thorn blocks 501 to the other thorn block 501, and at this time the baffle 59 moves from bottom to top along the top of the other thorn block 501, and then the baffle 59 approaches one of the thorn blocks 501 along the top of the other thorn block 501. At this time, after the baffle 59 moves to the connection point of the two thorn blocks 501, the bottom of the baffle 59 slides on the top of the other thorn block 501 and falls on the top of one of the thorn blocks 501, and repeats in sequence. At this time, the baffle 59 continues to move along the top of one of the thorn blocks 501, so that the cleaning position of the impurity removal roller cloth 51 and the sealing plate 25 remain changed, which is beneficial for the impurity removal roller cloth 51 to always move in a single direction, ensuring that the sealing surface of the sealing plate 25 is evenly stressed, and avoiding mixing of pollutants in different areas due to back and forth friction;

[0052] refer to Figure 8 、 Figure 9 、 Figure 10 、 Figure 11 and Figure 12As shown, when the sealing plate 25 is in contact with the impurity roller cloth 51 during movement, the moving arm 28 moves the concentric shaft column 65 synchronously, and then the concentric shaft column 65 moves to pull the folding arm 64 to move. At this time, the folding arm 64 moves relative to the folding plate 63, and the angle between the folding arm 64 and the folding plate 63 is constantly changing. During this movement, the folding arm 64 only adjusts the angle with the folding plate 63 and does not pull the folding plate 63 to move. Moreover, the folding arm 64 maintains a horizontal state with the folding plate 63 under continuous movement, so that the folding arm 64 pulls the folding plate 63 under movement. The movable folding plate 63 is displaced synchronously, and the movement of the folding plate 63 drives the connecting ring 61 to move synchronously, and the connecting ring 61 moves and pulls the support frame 52 to move, and the support frame 52 moves along the outer circumference of the rotating column 502 under the action of the rotating column 502, so that the sealing plate 25 moves a certain distance and then the debris removal roller 51 moves. The cleaning range and strength can be adjusted according to the actual position of the sealing plate 25, so that the debris removal roller 51 is synchronized with the movement trajectory of the sealing plate 25, avoiding leakage in the early stage of the movement of the sealing plate 25, accurately controlling the cleaning timing of the sealing plate 25, and facilitating the directionality of the cleaning process;

[0053] refer to Figure 8 、 Figure 9 、 Figure 10 、 Figure 11 and Figure 12 As shown, when the debris removing roller cloth 51 moves between the sealing plate 25, the concentric column 54 is driven to rotate synchronously by the rotation of the debris removing roller cloth 51, and then the concentric column 54 rotates to drive the frame 57, the support spring 58 and the baffle 59 to move synchronously. At this time, the baffle 59 moves from bottom to top along the top of another thorn block 501, and the baffle 59 moves upward to squeeze the support spring 58, so that the support spring 58 contracts and drives the baffle 59 to move along the guide inside the frame 57 during the upward movement. Then the baffle 59 moves along the top of another thorn block 501 to one of the thorn blocks 50 1, at this time, after the baffle 59 moves to the connection point of the two thorn blocks 501, the bottom of the baffle 59 slides on the top of the other thorn block 501 and falls on the top of one of the thorn blocks 501. In this process, the support spring 58 elastically stretches itself to give a downward thrust to one side of the baffle 59, and then pushes the baffle 59 to move downward along the frame 57, so that the baffle 59 maintains stable contact with the top of one of the thorn blocks 501, and moves back and forth in sequence, which can realize the concentric disk 55 to rotate in the same direction along the centering ring 56, making the quick-connect sealing cover diverse.

[0054] Working principle:

[0055] When in use;

[0056] refer to Figure 2 、 Figure 3 、 Figure 4 and Figure 5 As shown, by bringing the first quick-connect cover 21 close to the outside of the inoculation tube 11, and then rotating the first quick-connect cover 21 to drive the flexible pressure plate 33 to move downward along the outside of the inoculation tube 11, a portion of the first quick-connect cover 21 is inserted into the interior of the threaded frame 31, and a screw connection is formed between the interior of the first quick-connect cover 21 and the threaded frame 31, and the top of the threaded frame 31 contacts the interior of the first quick-connect cover 21. The first quick-connect cover 21 cannot be rotated anymore, so that the first quick-connect cover 21 and the inoculation tube 11 are screwed together, and the material trough 24 and the inoculation tube 11 remain overlapped, and the threaded ring 3 is rotated. It is screwed together with the threaded groove 34 formed at the bottom end of the first quick-connect cover 21, and the arc-pushing plate 35 is rotated synchronously with the rotation of the threaded ring 32, so that one side of the arc-pushing plate 35 passes through the gap between the flexible pressure plate 33 and the threaded ring 32. As one side of the arc-pushing plate 35 forms a slope with the outside of the flexible pressure plate 33, the arc-pushing plate 35 and the flexible pressure plate 33 form a friction and push the flexible pressure plate 33 toward the outside of the inoculation tube 11. Subsequently, the flexible pressure plate 33 and the inoculation tube 11 are in tight contact, so that the first quick-connect cover 21 and the inoculation tube 11 maintain a stable locking state.

[0057] refer to Figure 6 and Figure 7 As shown, the servo motor 43 drives the gear 45 to move synchronously, and then the gear 45 rotates and engages with the gear ring 42 to drive the middle ring 41 to realize circular motion between the second quick-connect cover 22 and the first quick-connect cover 21. At this time, the rotation of the middle ring 41 drives the fixed seat 26 to move synchronously, and the rotation of the middle ring 41 drives the position of the limiting groove 203 to move synchronously, and then the inside of the limiting groove 203 and the outside of the limiting column 202 keep moving, and the rotation of the middle ring 41 drives the synchronous movement of the cavity assembly, so that the opening angle of the cavity assembly in the first quick-connect cover 21 is adjusted, so that the inoculation size of the inoculation tube 11 is adjusted.

[0058] refer to Figure 6 、 Figure 7 、 Figure 10 、 Figure 11 and Figure 12As shown, the sealing plate 25 is moved simultaneously by the moving arm 28, and the movement of the sealing plate 25 keeps it in contact with the debris removing component 5. At this time, the bottom of the sealing plate 25 is located above the debris removing groove 53 and the bottom of the sealing plate 25 and the debris removing roller cloth 51 are kept tilted and staggered, and the contact area between the sealing plate 25 and the debris removing roller cloth 51 gradually increases. At this time, the moving arm 28 moves and drives the folding component 6 to move simultaneously, so that after the sealing plate 25 moves a certain distance, the debris removing roller cloth 51 moves under the pull of the folding component 6. The cleaning range and force can be adjusted according to the actual position of the sealing plate 25. The degree of rotation makes the movement trajectory of the debris removing roller 51 and the sealing plate 25 synchronized, avoiding leakage in the initial movement of the sealing plate 25. As the debris removing roller 51 moves and cooperates with the same-direction component, the concentric disk 55 can rotate in the same direction within the centering ring 56. Therefore, when sampling or adding liquid inside the fermentation tank 1, there is no need to frequently disassemble and assemble the first quick-connect cover 21 on the inoculation tube 11. It is only necessary to open the cavity opening component inside the first quick-connect cover 21 to complete the operation, reducing the operation time. After the first quick-connect cover 21 is quickly connected to the inoculation tube 11, it has a variety of uses, thereby improving the quick-connect use of the quick-connect sealing cover.
