Description

Technical Field

[0001] This invention relates to the field of crushing equipment technology, specifically to a crushing device for the preparation of bio-enzymes that prevents raw material contamination. Background Technology

[0002] Existing bio-enzyme raw material crushing processes mainly control contamination in two ways: one is to carry out the crushing operation in a sterile space, and the other is to disinfect and sterilize the crushed raw materials. However, the former requires the construction of an independent sterile environment, which has extremely high requirements for site cleanliness and consumes a lot of energy; the latter requires additional sterilization equipment and processes, which not only increases energy consumption, but may also affect the activity of raw materials due to secondary processing. Both methods have the problems of energy waste or stringent site requirements.

[0003] To address the specific needs of bio-enzyme preparation, Chinese Patent Publication No. CN117680252B discloses a raw material crusher for bio-enzyme preparation. This crusher features a raw material cylinder fixing mechanism and a feeding mechanism. A sliding, sealed structure allows the raw material to flow directly into the crushing chamber, preventing contamination during the pouring process. The equipment integrates a crushing chamber and a grinding chamber, switching between crushing and grinding modes via a drive cylinder-controlled tilting plate, and using a filter screen to control the raw material particle size. However, existing solutions still have shortcomings in terms of feed uniformity and crushing efficiency adaptability. Because the raw material cylinder is inverted and placed on top of the crushing cylinder, the feed speed can easily become uncontrollable during pouring, potentially causing material accumulation or uneven crushing within the crushing chamber. Furthermore, since most of the blades within the crushing cylinder are fixed, it is difficult to dynamically adjust them according to the real-time feed status, affecting the processing effect of raw materials with different properties. Summary of the Invention

[0004] To address the aforementioned issues, a crushing device for bio-enzyme preparation is provided to prevent raw material contamination. The feeding rate of the raw material is controlled by adjusting the opening of the feed inlet using a regulating mechanism. During its movement, the device synchronously drives a drive rod, which in turn moves the moving end. This causes multiple cutter holders to expand or contract at equal intervals between the fixed and moving ends, enabling the crushing mechanism to achieve differentiated crushing for raw materials with different properties. This solves the problem of uneven crushing caused by single-discharge. By dynamically changing the gap between the cutter holders, the device can flexibly adapt to changes in the particle size of the raw material.

[0005] To address the problems of existing technologies, this invention provides a crushing device for bio-enzyme preparation that prevents raw material contamination. The device includes a crushing cylinder and a crushing mechanism disposed within the crushing cylinder. A feed inlet is located at the top of the crushing cylinder, and an inverted raw material container is mounted on the feed inlet. A control mechanism for regulating the raw material feed rate is also located on the feed inlet. The crushing mechanism includes a fixed end fixedly connected to the crushing cylinder and a movable end movable along the axis of the crushing cylinder. Multiple equidistant cutter holders that slide along the axis of the crushing cylinder are disposed between the fixed end and the movable end, each cutter holder having multiple cutters. The crushing mechanism also includes a drive rod and a transmission assembly for synchronously adjusting the spacing between the multiple cutter holders. One end of the drive rod is connected to the control mechanism, and the other end is connected to the movable end. The transmission assembly is mounted on the multiple cutter holders. When the control mechanism moves the drive rod, the spacing between the cutter holders on the crushing mechanism changes with the feed rate.

[0006] Preferably, a rotatable drive shaft is provided inside the crushing cylinder. The surface of the drive shaft is provided with splines. Multiple cutter holders are sleeved on the drive shaft. The cutter holders are cylindrical structures. Adjacent cutter holders are nested together to form a telescopic nesting structure. The inner wall of the cutter holder is provided with a keyway that matches the splines.

[0007] Preferably, the tool holder is provided with a mounting shaft, and the transmission assembly includes a number of connecting rod components that are the same as and correspond one-to-one with the tool holders. Each connecting rod component is connected to two adjacent tool holders. The connecting rod component includes two mounting brackets that can move relative to each other in the horizontal direction. Each mounting bracket is hinged with a connecting rod, and the ends of the two connecting rods that are close to each other are sleeved on the mounting shaft of the adjacent tool holder.

[0008] Preferably, the cutter holder is provided with a partition plate, and the partition plate is provided with a sliding groove extending radially along the crushing cylinder. The transmission assembly also includes a mounting rod disposed between the moving end and the fixed end. The mounting rod is a telescopic structure and slides with the sliding groove. The mounting rod is sleeved on the mounting bracket of all connecting rod components.

[0009] Preferably, the control mechanism includes a baffle block and a drive assembly. The baffle plate is slidably disposed at the feed inlet along the axial direction of the crushing cylinder, the drive assembly is disposed below the baffle plate, and the drive rod is movable along the axial direction of the crushing cylinder and disposed below the drive assembly. Both the baffle block and the drive rod are connected to the drive assembly for transmission.

[0010] Preferably, a first screw extending along the axis of the crushing cylinder is provided below the blocking block, and a first sleeve threadedly engages with the first screw, the first sleeve being connected to the drive assembly for transmission.

[0011] Preferably, the drive rod includes a second screw connected to the moving end and a second sleeve threadedly engaged with the second screw, and the second sleeve is provided with a positioning element for fixing.

[0012] Preferably, a support frame is provided at the bottom of the crushing cylinder, and a rotatable turntable is provided below the support frame. Multiple fan-shaped screens are evenly distributed around the turntable, and the screen apertures of adjacent screens are arranged in ascending order. Multiple baffles matching the screens are provided on the support frame.

[0013] Preferably, a toothed ring is fitted around the edge of the turntable, a gear is installed inside the crushing cylinder that meshes with the toothed ring, and a first rotary drive motor is installed on the crushing cylinder to drive the gear to rotate.

[0014] Preferably, the control mechanism is equipped with a sensor for identifying raw materials.

[0015] The advantages of this invention compared to the prior art are:

[0016] 1. This invention utilizes a control mechanism that can be rotatably mounted on the feed inlet, or slidably mounted on the feed inlet along its axial direction. This allows for precise control of the feed rate by changing the opening of the feed inlet. Simultaneously, the movement of the control mechanism drives the drive rod of the crushing mechanism, which in turn pushes or pulls the moving end connected to the drive rod along the axial direction of the crushing cylinder. The movement of the moving end causes multiple cutter holders to expand or contract at equal intervals between the fixed end and the moving end, ensuring uniform variation in the spacing between the cutter holders. This leads to corresponding adjustments in the spacing between the cutters, enabling the crushing mechanism to achieve differentiated crushing for raw materials with different properties. This solves the problem of uneven crushing caused by single-pour operation. By dynamically changing the gap between the cutter holders, the equipment can flexibly adapt to changes in the particle size of the raw materials, reducing crushing blind spots and over-crushing caused by uneven feeding. This improves crushing efficiency while reducing the risk of damage to the activity of biological enzymes.

[0017] 2. This invention cleverly decouples the rotational motion of the drive shaft from the axial sliding of the cutter holder through the combination of splines and keyways. This achieves both the crushing function and the dynamic adjustment of the spacing, avoiding the limitations of traditional fixed cutter holders that cannot adapt to different feed rates. The telescopic nesting arrangement of adjacent cutter holders allows for multi-stage adjustment of the crushing gap within the limited space of the crushing cylinder, significantly improving space utilization. Simultaneously, it ensures that the cutter holders remain coaxial during sliding, effectively reducing vibration and noise caused by eccentricity and extending the service life of the equipment.

[0018] 3. This invention, through the arrangement of a support frame, a turntable, and multiple screens, enables rapid switching of screen aperture sizes without the need to disassemble and replace screens, significantly simplifying the operation process. It is particularly suitable for the fine grading requirements of raw material particle size in bio-enzyme preparation. The circumferentially uniform distribution of the turntable ensures the stability and regularity of rotation switching. Combined with the precise positioning of the baffles, it avoids screening chaos caused by multiple screen aperture sizes working simultaneously, thus improving screening accuracy.

[0031] To further understand the features, technical means, and specific objectives and functions achieved by the present invention, the present invention will be described in further detail below with reference to the accompanying drawings and specific embodiments.

[0032] like Figures 1 to 7 As shown: A crushing device for preparing bio-enzymes to prevent raw material contamination includes a crushing cylinder 1 and a crushing mechanism 12 disposed within the crushing cylinder 1. A feed inlet 11 is provided at the top of the crushing cylinder 1, and an inverted raw material container 111 is disposed on the feed inlet 11. A regulating mechanism 112 for regulating the raw material feeding rate is provided on the feed inlet 11. The crushing mechanism 12 includes a fixed end 121 fixedly connected to the crushing cylinder 1 and a movable end 122 movable along the axial direction of the crushing cylinder 1. Multiple equidistant grooves are disposed between the fixed end 121 and the movable end 122 along the crushing cylinder 1. The cylinder 1 has a sliding cutter holder 123, each of which is equipped with multiple cutters 1231. The crushing mechanism 12 is also equipped with a drive rod 124 and a transmission assembly 125 that synchronously adjusts the spacing between the multiple cutter holders 123. One end of the drive rod 124 is connected to the control mechanism 112, and the other end of the drive rod 124 is connected to the moving end 122. The transmission assembly 125 is set on the multiple cutter holders 123. When the control mechanism 112 drives the drive rod 124 to move, the spacing between the cutter holders 123 on the crushing mechanism 12 changes with the feeding rate.

[0033] When it is necessary to crush bio-enzyme raw materials, the raw materials enter the feed inlet 11 at the top of the crushing cylinder 1 through the raw material bucket 111. Because the raw material bucket 111 in the existing technology is inverted, although this facilitates feeding, it easily leads to uncontrollable feeding rates and uneven contact between the raw materials and the crushing mechanism 12. The traditional fixed crushing mechanism 12 is difficult to adapt to the crushing requirements of raw materials of different sizes. In this device, the control mechanism 112 can be rotatably installed on the feed inlet 11, or it can be slidably installed on the feed inlet 11 along its axial direction. By changing the opening of the feed inlet 11, the feeding rate of the raw materials can be precisely controlled. During the movement of the control mechanism 112, the drive rod 124 of the crushing mechanism 12 is simultaneously driven to move. Since the other end of the drive rod 124 is connected to the moving end 122 of the crushing mechanism 12, it pushes or pulls the moving end 122 to move along the axial direction of the crushing cylinder 1. Since the fixed end 121 is fixedly connected to the crushing cylinder 1 (a support can be installed inside the crushing cylinder 1 to connect to it), the movement of the moving end 122 causes multiple cutter holders 123 to expand or contract at equal intervals between the fixed end 121 and the moving end 122, ensuring that the distance between the multiple cutter holders 123 can change uniformly, driving the distance between the cutter 1231 to be adjusted accordingly, so that the crushing mechanism 12 can achieve differentiated crushing for raw materials with different physical properties.

[0034] Specifically, when the feeding rate increases, the moving end 122 moves away from the fixed end 121, and the distance between the cutter holders 123 increases to match the coarse crushing requirements of rapid feeding; when the feeding rate decreases, the moving end 122 moves closer to the fixed end 121, and the distance between the cutter holders 123 decreases to achieve fine crushing. Through dynamic adjustment, the distance between the cutter holders 123 and the feeding rate are adapted in real time to ensure that the raw materials can be effectively crushed under different feeding amounts.

[0035] By linking the control mechanism 112 with the crushing mechanism 12, the precise movement of the control mechanism 112 avoids raw material exposure and external contamination caused by traditional tilting methods. Combined with the enclosed structure of the crushing cylinder 1, this significantly improves the aseptic safety of the bio-enzyme preparation process. Simultaneously, the synchronized adjustment of the spacing between multiple cutter holders 123 ensures uniform contact between the raw material and the cutter 1231, solving the problem of uneven crushing caused by single-pour. By dynamically changing the gap between the cutter holders 123, the equipment can flexibly adapt to changes in raw material particle size, reducing crushing blind spots and over-crushing caused by uneven feeding. This improves crushing efficiency while reducing the risk of damage to bio-enzyme activity. Parameter self-adaptation is achieved through mechanical linkage, eliminating the need for complex electrical control systems. This approach combines reliability and cost advantages, making it suitable for efficient, low-damage crushing processes of various bio-enzyme raw materials.

[0036] It should be noted that the above structure is mainly for the initial crushing of biological enzymes. There are other processes afterward. The crushing tank can also be set up to be connected with the tanks of other processes to form a complete process.

[0037] like Figures 2 to 8 As shown: A rotatable drive shaft 13 is provided inside the crushing cylinder 1. The surface of the drive shaft 13 is provided with splines. Multiple cutter holders 123 are sleeved on the drive shaft 13. The cutter holders 123 are cylindrical structures. Adjacent cutter holders 123 are nested together to form a telescopic nesting structure. The inner wall of the cutter holder 123 is provided with a keyway that matches the splines.

[0038] The drive shaft 13 is powered by an external drive mechanism. When the drive shaft 13 rotates, the splines on its surface cooperate with the keyways on the inner wall of the cutter holder 123 to transmit the rotational torque of the drive shaft 13 to each cutter holder 123, so that all cutter holders 123 rotate synchronously with the drive shaft 13 to perform crushing operations on the raw materials in the crushing cylinder 1.

[0039] Because the adjacent cutter holders 123 adopt an interlocking telescopic nesting structure and slide on the spline through keyways, when the control mechanism 112 drives the moving end 122 to move along the axial direction of the crushing cylinder 1, the displacement of the moving end 122 drives all the cutter holders 123 to slide synchronously on the drive shaft 13 through the transmission assembly 125. The spline and keyway cooperation ensures that the cutter holders 123 continuously obtain rotational power during sliding and ensures that adjacent cutter holders 123 maintain coaxiality during telescopic nesting, so that the spacing of the cutter holders 123 can be dynamically and uniformly adjusted according to the feeding rate. In this process, the cylindrical structure of the cutter holders 123 enhances the structural stability of the cutter holders 123 during high-speed rotation and sliding, preventing deformation or displacement caused by uneven force.

[0040] By cleverly decoupling the rotational motion of the drive shaft 13 from the axial sliding motion of the cutter holder 123 through the spline and keyway combination, the crushing function is achieved while also meeting the requirements for dynamic spacing adjustment, avoiding the limitations of traditional fixed cutter holders 123 that cannot adapt to different feed rates. The telescopic nesting arrangement of adjacent cutter holders 123 allows for multi-stage adjustment of the crushing gap within the limited space of the crushing cylinder 1, significantly improving space utilization. Simultaneously, it ensures that the cutter holders 123 remain coaxial during sliding, effectively reducing vibration and noise caused by eccentricity and extending the equipment's service life. This design is suitable for scenarios in bio-enzyme preparation where strict requirements for raw material particle size are necessary, providing a reliable guarantee for the sterile and efficient crushing of bio-enzyme raw materials.

[0041] like Figures 2 to 10As shown: The tool holder 123 is provided with a mounting shaft 1232. The transmission assembly 125 includes a number of connecting rod components 1251 that are the same as and correspond one-to-one with the tool holders 123. Each connecting rod component 1251 is connected to two adjacent tool holders 123. The connecting rod component 1251 includes two mounting brackets 1253 that can move relative to each other in the horizontal direction. Each mounting bracket 1253 is hinged with a connecting rod 12511. The ends of the two connecting rods 12511 that are close to each other are sleeved on the mounting shaft 1232 of the adjacent tool holder 123.

[0042] When the control mechanism 112 drives the moving end 122 to move via the drive rod 124, the connecting rod component 1251 of the transmission assembly 125 moves accordingly. The two mounting brackets 1253 of each connecting rod component 1251 move relative to each other in the horizontal direction. Since the mounting bracket 1253 is hinged to the connecting rod 12511, this movement is converted into an angle change of the connecting rod 12511. When the two mounting brackets 1253 move away from each other in the horizontal direction, the connecting rod 12511 hinged to the mounting bracket 1253 unfolds outward. Through the connecting end sleeved on the mounting shaft 1232 of the adjacent cutter holder 123, it pulls the adjacent cutter holders 123 closer to each other in the axial direction of the crushing cylinder 1, reducing the distance between the two adjacent cutter holders 123. When the mounting brackets 1253 move towards each other, the connecting rod 12511 retracts inward, pushing the adjacent cutter holders 123 away from each other in the axial direction, increasing the distance between the two adjacent cutter holders 123. Since each connecting rod component 1251 is connected to an adjacent cutter holder 123 in a one-to-one manner, and the horizontal movement of the mounting frame 1253 is linked together by the transmission assembly 125, all cutter holders 123 can adjust their spacing synchronously and at equal intervals, so that the crushing gap of the cutter 1231 on two adjacent cutter holders 123 changes dynamically with the feeding rate, thereby achieving adaptive crushing of raw materials with different flow rates.

[0043] The transmission assembly 125 utilizes the geometric motion characteristics of the mechanical connecting rod 12511 to convert the horizontal driving force into an adjustment of the spacing between the cutter holders 123 along the axial direction of the crushing cylinder 1. This achieves synchronous linkage of multiple cutter holders 123 without the need for a complex transmission mechanism, resulting in a compact structure and high transmission efficiency. By setting multiple connecting rod components 1251 corresponding to the cutter holders 123, the uniformity and consistency of the spacing adjustment between adjacent cutter holders 123 are ensured, avoiding crushing blind spots or equipment vibration caused by uneven local force. The hinged connection between the mounting bracket 1253 and the connecting rod 12511, and the sleeve fit between the connecting rod 12511 and the mounting shaft 1232, allow the cutter holders 123 to slide freely along the axis while maintaining structural stability when the drive shaft 13 rotates the cutter holders 123, achieving dual functionality of rotary crushing and spacing adjustment. In addition, the horizontally movable mounting bracket 1253 effectively utilizes the space inside the crushing cylinder 1, making the layout of the transmission assembly 125 more reasonable. Combined with the closed structure of the crushing cylinder 1, it further reduces the risk of raw material leakage and meets the stringent requirements for equipment sealing, reliability and crushing accuracy in the bio-enzyme preparation process.

[0044] like Figures 5 to 10 As shown: A partition plate 1233 is provided inside the blade holder 123. A sliding groove 12331 extending radially along the crushing cylinder 1 is provided on the partition plate 1233. The transmission assembly 125 also includes a mounting rod 1252 disposed between the moving end 122 and the fixed end 121. The mounting rod 1252 is a telescopic structure and slides with the sliding groove 12331. The mounting rod 1252 is sleeved on the mounting bracket 1253 of all connecting rod components 1251.

[0045] When the control mechanism 112 drives the moving end 122 to move along the axis of the crushing cylinder 1, the mounting rod 1252 located between the moving end 122 and the fixed end 121 extends and retracts accordingly. At the same time, the two connecting rods 12511 will fold or unfold due to their hinged ends. Since the mounting rod 1252 is sleeved on the mounting bracket 1253 of all the connecting rod components 1251, the mounting rod 1252 will slide along the sliding groove 12331 on the partition plate 1233 while extending and retracting. Thus, the axial extension and retraction of the mounting rod 1252 will be converted into a radial thrust or pull on the mounting bracket 1253. The force enables the movement of multiple mounting brackets 1253. When the mounting rod 1252 extends, it pulls the mounting brackets 1253 radially inward, causing two mounting brackets 1253 on the same connecting rod component 1251 to move towards each other in the horizontal direction. Through the hinged connecting rod 12511, it pulls adjacent tool holders 123 closer to each other in the axial direction, increasing the distance between the two adjacent tool holders 123. When the mounting rod 1252 retracts, the radial thrust causes the mounting brackets 1253 to move away from each other, and the connecting rod 12511 pushes the two adjacent tool holders 123 closer together, decreasing the distance between the two adjacent tool holders 123.

[0046] During this process, the groove 12331 of the partition 1233 provides radial guidance for the mounting rod 1252, ensuring that the telescopic movement of the mounting rod 1252 is accurately transmitted to each mounting bracket 1253, realizing the synchronous action of all connecting rod components 1251, thereby driving multiple tool holders 123 to adjust the spacing evenly, so that the crushing gap of the tool 1231 is dynamically matched with the feeding rate.

[0047] The geometric characteristics of mechanical transmission are utilized to achieve synchronous and equidistant adjustment of the spacing between multiple tool holders 123. The partition plate 1233 and the slide groove 12331 not only provide support and guidance for the mounting rod 1252 and enhance the stability of the transmission process, but also effectively utilize the internal space of the tool holder 123 through radial layout, making the transmission assembly 125 compact and avoiding the problem of traditional axial transmission occupying too much space inside the crushing cylinder 1.

[0048] The mounting rod 1252, which houses all the mounting brackets 1253, ensures that a single power source can drive all the connecting rod components 1251 to work together, reducing energy loss in the transmission process and improving the equipment's response speed. Furthermore, the sliding fit between the slide groove 12331 and the mounting rod 1252 is precision-machined, reducing friction and extending the equipment's service life. Combined with the nested structure of the cutter holder 123, this further enhances the sealing of the crushing process, preventing raw material leakage or external contamination, and meeting the dual requirements of a sterile environment and crushing precision in bio-enzyme preparation.

[0049] like Figures 2 to 5 As shown: The control mechanism 112 includes a blocking block 1121 and a drive assembly 1122. The blocking block 1121 is slidably disposed at the feed inlet 11 along the axial direction of the crushing cylinder 1. The drive assembly 1122 is disposed below the blocking block 1121. The drive rod 124 is movable along the axial direction of the crushing cylinder 1 and is disposed below the drive assembly 1122. Both the blocking block 1121 and the drive rod 124 are connected to the drive assembly 1122 in a transmission manner.

[0050] The drive assembly 1122 is preferably a bidirectional cylinder, hydraulic cylinder, or electric actuator. When the drive assembly 1122 is started, its output driving force is synchronously transmitted along the axis of the crushing cylinder 1 to the blocking block 1121 and the drive rod 124, causing the blocking block 1121 to slide along the axis of the feed inlet 11. By changing the opening of the feed inlet 11, the feed rate of the raw material is controlled. At the same time, the driving force is transmitted to the moving end 122 of the crushing mechanism 12 through the drive rod 124. The transmission assembly 125 drives multiple cutter holders 123 to synchronously adjust their spacing, so that the crushing gap between the cutters 1231 is dynamically matched with the feed rate. This synchronous drive mechanism ensures that when the feed rate increases, the spacing between the cutter holders 123 increases accordingly to adapt to the crushing requirements of rapid feeding; when the feed rate decreases, the spacing between the cutter holders 123 decreases synchronously to achieve fine crushing, thus forming an adaptive closed-loop control system that adapts to the feed rate. This significantly improves the collaborative working efficiency of the equipment. The synchronous transmission between the barrier block 1121 and the drive rod 124 avoids parameter matching errors that may occur with traditional step-by-step adjustment methods, ensuring that the crushing process is always in optimal working condition. The modular layout of the drive assembly 1122 makes the equipment structure more compact, reduces the use of additional transmission components, and lowers the risk of failure and maintenance costs. It meets the adaptability requirements of different working environments in the bio-enzyme preparation process, and achieves synchronous adjustment of multiple parameters through a single power input, providing a reliable guarantee for the efficient and precise crushing of bio-enzyme raw materials.

[0051] It should be noted that the drive component 1122 can also be configured with other drive structures to drive the barrier block 1121 to move. By directly connecting the barrier block 1121 to the drive rod 124 of the crushing mechanism 12, linkage can be achieved.

[0052] like Figures 2 to 5 As shown: A first screw 11212 extending along the axis of the crushing cylinder 1 is provided below the barrier block 1121. A first sleeve 11213 threadedly engages with the first screw 11212. The first sleeve 11213 is connected to the drive assembly 1122 for transmission.

[0053] After the drive assembly 1122 adjusts the opening of the feed inlet 11, it can perform auxiliary fine adjustment by rotating the first screw 11212 below the obstruction block 1121. The first screw 11212 extends along the axis of the crushing cylinder 1 and forms a threaded pair with the first sleeve 11213 sleeved on it. The first screw 11212 is driven to rotate manually or by a servo motor. Due to the threaded engagement, the first sleeve 11213 moves up and down slightly along the axial direction, causing the obstruction block 1121 to adjust its opening from the main drive position. This precisely matches the differences in feed requirements caused by changes in the viscosity or particle size of the raw materials. After adjustment, the transmission connection between the first sleeve 11213 and the drive assembly 1122 remains stable, ensuring that the auxiliary adjustment amount is accurately transmitted to the feed inlet 11, so that the opening and the distance between the crushing mechanism 12 cutter holder 123 achieve a better match. This design compensates for the lack of precision in the drive mechanism, meeting the stringent requirements for raw material flow rate in bio-enzyme preparation. The self-locking function of the threaded pair effectively prevents the position drift of the barrier block 1121 caused by long-term vibration or temperature changes, ensuring long-term stability after opening adjustment. It features a simple structure, low modification cost, and strong adaptability, significantly improving the precision and reliability of feed control, providing dual assurance for the uniform crushing of bio-enzyme raw materials and precise control of process parameters.

[0054] like Figures 2 to 7 As shown: The drive rod 124 includes a second screw 1241 connected to the moving end 122 and a second sleeve 1242 threadedly engaged with the second screw 1241. The second sleeve 1242 is provided with a positioning element for fixing.

[0055] After the drive assembly 1122 adjusts the spacing between the multiple cutter holders 123 of the crushing mechanism 12 via the drive rod 124, the second screw 1241 connected to the moving end 122 can be rotated. Utilizing its threaded engagement with the second sleeve 1242, the second sleeve 1242 moves slightly along the axis of the crushing cylinder 1, thereby driving the moving end 122 to achieve telescopic adjustment. After adjustment, the positioning components (such as locking nuts, positioning pins, etc.) on the second sleeve 1242 are operated to fix the relative rotational position of the second sleeve 1242 and the second screw 1241. This prevents the screw from rotating due to vibration of the drive shaft 13 or impact force of the raw material during crushing, ensuring that the spacing between the cutter holders 123 remains stable at the target value. This meets the stringent requirements for crushing gaps in bio-enzyme preparation, avoiding uneven crushing or over-grinding of raw materials due to spacing deviations. The locking effect of the positioning components on the screw rotation effectively solves the problem of displacement caused by vibration in traditional threaded drives, making it particularly suitable for high-speed crushing scenarios, ensuring that the cutter holders 123 maintain stable spacing during high-speed rotational cutting.

[0056] like Figures 2 to 7As shown: A support frame 14 is provided at the bottom of the crushing cylinder 1, and a rotating turntable 141 is provided below the support frame 14. Multiple fan-shaped screens 1411 are evenly distributed around the turntable 141. The screen holes of adjacent screens 1411 are arranged in order from small to large. Multiple baffles 142 that match the screens 1411 are provided on the support frame 14.

[0057] When the crushed raw materials are screened, the turntable 141 below the support frame 14 rotates around its central axis, and the fan-shaped screens 1411 evenly distributed circumferentially on the turntable 141 rotate synchronously with the turntable 141. Because the support frame 14 is provided with multiple baffles 142 that match the screens 1411, the support frame 14 has multiple fan-shaped areas that can expose the screens 1411. This allows the screens 1411 that match the raw materials to be fully exposed during the rotation of the turntable 141, while the remaining fan-shaped screens 1411 are blocked by the baffles 142. Because the aperture sizes of adjacent sector screens 1411 are arranged in ascending order (screen 1411 in the figure is for illustrative purposes only and different sizes of screen holes are not shown), each rotation of the turntable 141 switches to the next size of screen hole, enabling the grading and screening of raw materials of different particle sizes. When the raw material particle size is small, the small screen hole area is exposed to intercept large particles of impurities; when the raw material needs to pass through quickly, the screen hole area is switched to improve screening efficiency, thus flexibly adjusting the screening specifications according to the crushing process requirements. This allows for rapid switching of screen hole specifications without disassembling and replacing screen 1411, significantly simplifying the operation process, and is particularly suitable for the fine grading requirements of raw material particle size in bio-enzyme preparation. The circumferentially uniform distribution of the turntable 141 ensures the stability and regularity of rotation switching, and, combined with the precise positioning of the baffle 142, avoids screening chaos caused by multiple screen hole sizes working simultaneously, improving screening accuracy.

[0058] like Figures 2 to 6 As shown: A gear ring 1412 is fitted around the edge of the turntable 141, and a gear 15 is provided inside the crushing cylinder 1 to mesh with the gear ring 1412. A first rotary drive motor 151 for driving the gear 15 to rotate is provided on the crushing cylinder 1.

[0059] When it is necessary to switch the screen aperture size on the turntable 141, the first rotary drive motor 151 starts, driving the gear 15 connected to it to rotate. Since the gear 15 meshes with the gear ring 1412 on the edge of the turntable 141, the rotation of the gear 15 is transmitted to the turntable 141 through the gear ring 1412, causing the turntable 141 to rotate uniformly around its central axis. This allows the corresponding screen aperture 1411 to be exposed, thus meeting the screening requirements for different raw material particle sizes.

[0060] like Figures 2 to 6 As shown: The control mechanism 112 is equipped with a sensor for identifying raw materials.

[0061] The control mechanism 112 is equipped with a sensor (not shown in the figure), preferably a photoelectric sensor, which is installed on the feed inlet 11. It identifies the particle size, flow rate, and distribution of the raw material by detecting the degree of light obstruction. When the raw material passes through the detection area, the sensor converts the physical signal into an electrical signal and transmits it to the back-end control system. Based on the sensor data, the back-end control system automatically adjusts the parameters of the drive component 1122. If the raw material particles are too large, the control mechanism 112 reduces the opening of the feed inlet 11 and the distance between the cutter holders 123 through threaded adjustment to enhance the crushing intensity. If the flow rate fluctuates, the screen 1411 and the rotary table 141 are linked to switch apertures to match the screening efficiency. This sensor allows the control mechanism 112 to perceive the raw material status in real time, overcoming the limitations of traditional equipment that relies on preset parameters. Non-contact detection has no physical loss, accurately captures particle differences in the raw material, provides a basis for dynamic adjustment of crushing parameters, and improves the level of automation and intelligence. The linkage mechanism between the sensor and the control mechanism 112 shortens the parameter adjustment cycle, enabling the system to quickly adapt to changes in raw materials and maintain stable crushing effects in continuous production, providing support for the efficient and refined production of bio-enzymes.
