Description

Technical Field

[0001] This utility model relates to the technical field of cattle feed mixing and ration machine, and more specifically, it relates to a cattle feed mixing and ration machine. Background Technology

[0002] In existing technologies, most cattle feed mixers are equipped with overload protection devices to prevent motor overload. However, these overload protection thresholds are usually fixed and cannot be flexibly adjusted to meet actual usage needs. This design limitation manifests in several ways in practical applications. Different types of feed ingredients have different physical properties, such as moisture content, viscosity, fiber content, and density. These differences directly affect the load requirements during mixing, and variations in the mixing volume also directly impact the motor load. In these complex and variable production environments, fixed-threshold overload protection devices struggle to meet the diverse needs of farms: excessively low thresholds lead to frequent equipment shutdowns, severely impacting production efficiency and feed quality; excessively high thresholds may fail to respond promptly to actual overload conditions, increasing the risk of motor damage and equipment failure, ultimately leading to increased maintenance costs and extended production cycles, resulting in significant economic losses for farms.

[0003] Secondly, while some equipment achieves flexible adjustment of the protection threshold through the cooperation of certain components, its simple structure and low stability make it prone to displacement due to equipment operation and external forces. This leads to changes in the adjusted protection threshold, and this design flaw manifests as serious reliability issues in actual use. These simple adjustment structures are typically simple in design, and under the continuous action of the mixer during long-term operation, the components are prone to displacement. Furthermore, the periodic impact loads during feed mixing will generate repeated impact stress on the adjustment mechanism, gradually leading to minute displacements of the adjustment components. When the protection threshold changes unpredictably, it may cause the threshold to decrease, frequently triggering overload protection, resulting in production interruptions and low efficiency. On the other hand, it may also cause the threshold to increase, resulting in the loss of effective protection and increasing the risk of equipment damage. More seriously, operators often cannot detect these minute threshold changes until a serious malfunction occurs. This not only increases the difficulty and cost of equipment maintenance but may also force adjustments to the production plan due to sudden failures, affecting the stability of feed supply and animal growth cycle management throughout the farm. Utility Model Content

[0004] (a) Technical problems to be solved

[0005] In view of the problems existing in the prior art, this utility model provides a cattle feed mixing ration machine to solve the technical problems mentioned in the background art.

[0006] (II) Technical Solution

[0007] To achieve the above objectives, this utility model provides the following technical solution: a cattle feed mixing ration machine, comprising a mixing chamber, a protective device provided on the side wall of the mixing chamber, the protective device comprising a rotating sleeve, a linkage sleeve, a linkage rod, a linkage groove, a push spring, a screw sleeve, a mixing groove, a push block, a mixing block, and a linkage frame, the rotating sleeve being rotatably mounted on the outside of the linkage sleeve, the linkage sleeve being rotatably mounted on the outside of the linkage rod, the linkage groove being opened on the outside of the linkage rod, the two ends of the push spring being connected to the push block and the mixing block respectively, the outer wall of the screw sleeve being movably connected to the inner wall of the rotating sleeve by threads, the mixing groove being opened in the linkage sleeve, the push block being movably disposed in the mixing groove, the mixing block being movably disposed on one side of the linkage frame, and one end of the linkage frame being engaged in the linkage groove. A fastening mechanism is provided on the outside of the linkage sleeve. The fastening mechanism includes a return spring, a movable plate, a movable groove, a fastening spring, a fastening block, a fastening sleeve, a limiting plate, a restricting plate, a fixing block, a return block, and a round block. The two ends of the return spring are respectively connected to the fixing block and the return block. The movable plate is rotatably mounted on the outside of the linkage sleeve. The movable groove is opened on the movable plate. The two ends of the fastening spring are respectively connected to two adjacent fastening blocks. Multiple fastening blocks are movably arranged on one side of the rotating sleeve. The fastening sleeve is slidably mounted on the outside of the linkage sleeve. The limiting plate is fixedly connected to one side of the fastening sleeve. Three restricting plates are fixedly connected to one side of the limiting plate. The fixing block is fixedly mounted on the outside of the linkage sleeve. The return block is fixedly mounted on one side of the movable plate. Multiple round blocks are fixedly mounted on the outside of the linkage sleeve.

[0008] This utility model is further configured such that a protective shell is detachably provided above the mixing chamber, a sprocket is provided above the protective shell, a motor is detachably provided at the top of the sprocket, the output end of the motor is connected to the top of the linkage sleeve, a stirring rod is rotatably provided inside the mixing chamber, multiple blades are detachably provided on the outside of the stirring rod, the top of the stirring rod is connected to the bottom of the linkage rod, and a protective side plate is detachably provided on the outside of the mixing chamber. This structural design realizes the modular assembly of various components of the equipment. The connection between the linkage sleeve and the motor output end, as well as the connection between the stirring rod and the linkage rod, constitute a complete power transmission path, ensuring mixing efficiency and uniformity.

[0009] The present invention is further configured such that a return rod is connected to one side of the return block, and a return hole is opened in the fixed block. One end of the return rod slides into the return hole. This structural design provides precise axial guidance and stable support for the return block and the return spring. The sliding cooperation between the return rod and the return hole ensures that the return block's reset action under the action of the return spring is carried out along a predetermined trajectory, avoiding the return block's offset or shaking during the reset process.

[0010] The present invention is further configured such that a movable spring is connected to one side of the fastening sleeve, and a thrust bearing is connected to the other side of the movable spring. The thrust bearing is detachably installed on one side of the movable plate. This design provides an automatic reset function for the fastening sleeve through the movable spring, while the introduction of the thrust bearing significantly reduces the frictional resistance between the movable plate and the fastening sleeve, making the fastening sleeve slide more smoothly.

[0011] The present invention is further configured such that a sliding groove is provided on the outer side of the linkage sleeve, and a slider is slidably provided in the sliding groove. The slider is fixedly installed on the inner side of the fastening sleeve. This sliding guide structure ensures that the trajectory of the fastening sleeve is accurate and controllable during the movement process, and prevents the fastening sleeve from rotating or deviating during the sliding process. The precise cooperation between the slider and the sliding groove provides stable support and guidance for the fastening sleeve, while also restricting the degree of freedom of movement of the fastening sleeve, so that it can only move in a straight line along the preset track.

[0012] The present invention is further configured such that a fastening groove is provided in the fastening block, and multiple fastening rails are fixedly provided on one side of the rotating sleeve. The fastening block is slidably installed on the outside of the fastening rails through the fastening groove. A fastening wheel is rotatably provided on one side of the fastening block. The fastening wheel is engaged between two circular blocks. Through the sliding cooperation between the fastening block and the fastening rail and the engagement positioning between the fastening wheel and the circular blocks, a reliable mechanical locking mechanism is formed. When the fastening wheel is engaged between the two circular blocks, the rotating sleeve is fixed at a specific angle position and cannot rotate, thereby locking the adjustment result of the protection threshold.

[0013] The present invention is further configured such that a mating block is fixedly provided on the inner side of the threaded sleeve, and a mating groove is provided on the side wall of the linkage sleeve. The mating block slides in the mating groove, and the inner wall of the threaded sleeve is connected to the push block through the mating block. This design achieves axial movement of the threaded sleeve without rotation through the sliding fit of the mating block and the mating groove, ensuring that the threaded sleeve can only move along the axial direction without rotating under the drive of the rotating sleeve.

[0014] (III) Beneficial Effects

[0015] Compared with the prior art, this utility model provides a cattle feed mixing ration machine, which has the following beneficial effects:

[0016] 1. The protective device, through the ingenious cooperation of components such as a rotating sleeve, linkage sleeve, linkage rod, linkage groove, push spring, screw sleeve, mixing groove, push block, mixing block, and linkage frame, achieves flexible adjustment of the protection threshold. This perfectly solves the problem in existing technologies where a fixed protection threshold cannot adapt to the physical properties of different feeds. When the stirring rod and blades encounter resistance exceeding the set threshold, the inner wall of the linkage groove exerts pressure on one end of the linkage frame. Due to the rounded corner treatment at one end of the linkage frame and the rounded corner design of the linkage groove, the linkage frame can smoothly slide out of the linkage groove and apply downward pressure to the mixing block through its arc design, causing the mixing block to move along... The mixing tank slides and, together with the push block, squeezes the push spring, achieving instantaneous separation between the motor and the mixing system. This allows the motor to idle and avoid damage. Through the design of a series of components such as the rotating sleeve and the screw sleeve, the protective device can adjust the protection threshold through simple operation based on factors such as the physical characteristics of different types of feed, the differences in raw material properties caused by seasonal climate changes, and changes in the mixing volume. This avoids frequent shutdowns due to excessively low thresholds, which affect production efficiency, and also prevents the risk of failure to respond to true overload situations due to excessively high thresholds. This effectively reduces equipment maintenance costs and economic losses caused by extended production cycles.

[0017] 2. The fastening mechanism, through the precise coordination of multiple components including a return spring, movable plate, movable groove, fastening spring, fastening block, fastening sleeve, limit plate, limiting plate, fixing block, return block, and round block, constructs a multi-layered locking system. This fundamentally solves the problems of simple adjustment structures and low stability in existing technologies. After the protection threshold is adjusted, the design of components such as the return spring, return rod, and return block limits the movable plate and movable groove, forming the first layer of locking. The misalignment design of the movable groove, limit plate, and limiting plate, combined with the slider and groove limiting the fastening sleeve, forms the second layer of locking. The fastening block drives the fastening wheel to engage between the two round blocks and, under the limiting action of the inner wall of the fastening sleeve, cannot move outward, forming the third layer of locking. The triple locking mechanism ultimately prevents the rotating sleeve from turning. This multi-locking mechanism remains stable even under continuous vibrations, periodic impact loads, and harsh environments generated by the mixer's long-term operation. It effectively prevents the adjusted structure from shifting due to external forces, thus avoiding changes in the protection threshold. In addition, multiple sets of precise matching structures, such as the slider and groove, the mating block and groove, and the return rod and return hole, further enhance the stability and reliability of the entire system. This allows operators to carry out production operations with confidence, without worrying about frequent shutdowns or equipment damage risks caused by unexpected changes in the protection threshold. It significantly improves the service life and production efficiency of the equipment, providing a reliable guarantee for the stability of feed supply and animal growth cycle management in the farm.

The protective device includes a rotating sleeve 2, a linkage sleeve 3, a linkage rod 4, a linkage groove 5, a push spring 6, a screw sleeve 7, a mixing groove 8, a push block 9, a mixing block 10, and a linkage frame 11. The rotating sleeve 2 is rotatably mounted on the outside of the linkage sleeve 3, and the linkage sleeve 3 is rotatably mounted on the outside of the linkage rod 4. The linkage groove 5 is located on the outside of the linkage rod 4. The two ends of the push spring 6 are respectively connected to the push block 9 and the mixing block 10. The outer wall of the screw sleeve 7 is movably connected to the inner wall of the rotating sleeve 2 via threads. The mixing groove 8 is located in the linkage sleeve 3. The push block 9 is movably disposed in the mixing groove 8. The mixing block 10 is movably disposed on one side of the linkage frame 11. One end of the linkage frame 11 is inserted into the linkage groove 5. A fastening mechanism is provided on the outside of the linkage sleeve 3, including a return mechanism. The system includes a spring 12, a movable plate 13, a movable groove 14, a fastening spring 15, a fastening block 16, a fastening sleeve 17, a limiting plate 18, a restricting plate 19, a fixing block 20, a return block 21, and a round block 22. The two ends of the return spring 12 are connected to the fixing block 20 and the return block 21, respectively. The movable plate 13 is rotatably mounted on the outside of the linkage sleeve 3. The movable groove 14 is opened on the movable plate 13. The two ends of the fastening spring 15 are connected to two adjacent fastening blocks 16, respectively. Multiple fastening blocks 16 are movably mounted on one side of the rotating sleeve 2. The fastening sleeve 17 is slidably mounted on the outside of the linkage sleeve 3. The limiting plate 18 is fixedly connected to one side of the fastening sleeve 17. Three restricting plates 19 are fixedly connected to one side of the limiting plate 18. The fixing block 20 is fixedly mounted on the outside of the linkage sleeve 3. The return block 21 is fixedly mounted on one side of the movable plate 13. Multiple round blocks 22 are fixedly mounted on the outside of the linkage sleeve 3.

[0029] A protective shell 23 is fixedly installed on the side wall of the mixing chamber 1. Two motors 25 are detachably mounted on the side wall of the protective shell 23. A linkage sleeve 3 is located inside the protective shell 23, and a sprocket 24 is fixedly connected to one end of each linkage sleeve 3. The output ends of the two motors 25 are respectively fixedly connected to the two sprockets 24 at the top. Multiple stirring rods 26 are rotatably mounted inside the mixing chamber 1. Multiple blades 27 are detachably mounted on the outer side of the stirring rods 26. The top end of the stirring rod 26 is connected to the bottom end of the linkage rod 4. Protective side plates 28 are detachably mounted on both sides of the mixing chamber 1 corresponding to the motors 25. The two corresponding sprockets 24 at the top and bottom are connected by a chain 29.

[0030] In this embodiment of the utility model: a base 30 is provided at the bottom of the mixing chamber 1, the mixing chamber 1 is rotatably mounted on the base 30, a support leg 31 is fixedly provided on the lower end face of the base 30, and a lifting component 32 is provided on the base 30. The lifting component 32 is used to flip the mixing chamber 1 to the side, thereby facilitating unloading.

[0031] In this embodiment, when the device needs to be used, the motor 25 is turned on. First, the motor 25 drives the sprocket 24 connected to the output end to rotate. Then, through the transmission cooperation between the sprocket 24 and the chain 29, all the linkage sleeves 3 are driven to rotate. The linkage sleeves 3 drive the mixing groove 8 opened on the inner side to rotate, thereby driving the mixing block 10, the push block 9, the push spring 6, and the linkage frame 11 to rotate. Then, the linkage frame 11 drives the linkage rod 4 to rotate through the cooperation with the linkage groove 5. Then, the linkage rod 4 drives the stirring rod 26 and the blade 27 installed on its outer side to rotate, realizing the stirring and mixing of raw materials. After the stirring and mixing is completed, the discharged feed can be collected through external equipment. When the protection threshold is triggered... When the stirring rod 26 and the blade encounter resistance exceeding the set threshold, the inner wall of the linkage groove 5 on the outer side of the linkage rod 4 presses against one end of the linkage frame 11. Due to the rounded corner treatment of one end of the linkage frame 11 and the rounded corner design of the linkage groove 5, one end of the linkage frame 11 will slide out from one end of the linkage groove 5. Due to the arc design of the other end of the linkage frame 11 and the special structural design of the mixing block 10, one end of the linkage frame 11 presses down on the mixing block 10, causing the mixing block 10 to slide along the mixing groove 8. Since the push block 9 does not move, the mixing block 10, together with the push block 9, presses against the push spring 6, causing the motor 25 to drive the linkage sleeve 3 and other components to run idle, realizing no-load protection and preventing damage to the motor 25.

[0032] Please see Figures 3-5 As a further implementation of the overall equipment: a return rod 33 is connected to one side of the return block 21, and a return hole 34 is opened in the fixed block 20, with one end of the return rod 33 slidingly inserted into the return hole 34.

[0033] A movable spring 35 is connected to one side of the fastening sleeve 17, and a thrust bearing 36 is connected to the other side of the movable spring 35. The thrust bearing 36 is detachably installed on one side of the movable plate 13.

[0034] A sliding groove 37 is provided on the outer side of the linkage sleeve 3, and a slider 38 is slidably provided in the sliding groove 37. The slider 38 is fixedly installed on the inner side of the fastening sleeve 17.

[0035] The fastening block 16 has a fastening groove 39. Multiple fastening rails 40 are fixed on one side of the rotating sleeve 2. The fastening block 16 is slidably installed on the outside of the fastening rails 40 through the fastening groove 39. A fastening wheel 41 is rotatably provided on one side of the fastening block 16. The fastening wheel 41 is inserted between two round blocks 22.

[0036] A mating block 42 is fixedly provided on the inner side of the threaded sleeve 7, and a mating groove 43 is provided on the side wall of the linkage sleeve 3. The mating block 42 slides in the mating groove 43, and the inner wall of the threaded sleeve 7 is connected to the push block 9 through the mating block 42.

[0037] More specifically, when the protection threshold needs to be adjusted, firstly, the movable plate 13 is rotated forward. Then, the movable plate 13 will drive the movable groove 14 to rotate forward, and the movable plate 13 will drive the thrust bearing 36 on one side and the return block 21 installed on the other side to rotate forward. Then, the return block 21 will drive the return rod 33 on one side to rotate forward along the return hole 34. The return block 21 will cooperate with the fixed block 20 to compress the return spring 12. When the return spring 12 is compressed to its limit, the movable groove 14 will rotate to the position corresponding to the limiting plate 19, and then push the fastening sleeve 17. The fastening sleeve 17 will drive the inner slider 38 to slide along the slide groove 37, and the fastening sleeve 17 will drive the limiting plate 18 and the limiting plate 19 on one side to slide, so that... As the limiting plate 18 and the restricting plate 19 gradually slide through the movable groove 14, the fastening sleeve 17, in conjunction with the thrust bearing 36, compresses the movable spring 35. When the movable spring 35 is compressed to its limit, the restricting plate 19 closest to the fastening sleeve 17 slides through the movable groove 14 and moves to the other side of the movable plate 13. Then, the movable plate 13 is released, and the return spring 12 pushes the return block 21 to rotate and reset. The return block 21 then drives one side of the return rod 33 to rotate and reset along the return hole 34. The return block 21, through the movable plate 13, drives the movable groove 14 and the thrust bearing 36 to rotate and reset, causing the movable groove 14 to rotate and reset to a position not corresponding to the restricting plate 19. Then, the limiting plate 18 and the restricting plate 19 closest to the fastening sleeve 17... The limiting plate 19 cooperates to limit the fastening sleeve 17 to one side of the movable plate 13, so that the inner wall of the fastening sleeve 17 no longer limits the outer wall of the fastening wheel 41. Then, the rotating sleeve 2 is rotated in the forward direction. The rotating sleeve 2 drives one side of the fastening rail 40 to rotate in the forward direction. Then, the fastening rail 40 drives the fastening block 16 and the fastening wheel 41 to rotate in the forward direction through the fastening groove 39. This causes the fastening block 16 to drive the fastening wheel 41 to move out from between the two round blocks 22. Then, the fastening wheel 41 will drive the fastening block 16 to slide outward along the fastening rail 40 and the fastening groove 39. Then, the fastening block 16 will drive the fastening spring 15 to stretch outward. Since the outer wall of the threaded sleeve 7 is movably connected to the inner wall of the rotating sleeve 2 through the thread, and the mating block 42 and the mating groove 43 limit the threaded sleeve 7, the threaded sleeve 7 is free from... The screw sleeve 7 rotates, and then the screw sleeve 7 synchronously drives the mating block 42 to slide upward along the mating groove 43. Then the mating block 42 drives the inner push block 9 to slide along the adjusting groove 8, shortening the distance between the push block 9 and the adjusting block 10. This causes the push spring 6 to be compressed to a certain extent by both, increasing the thrust exerted by the push spring 6 on the adjusting block 10. This, in turn, increases the thrust exerted by the adjusting block 10 on the linkage frame 11. As a result, one end of the linkage frame 11 needs to withstand a greater force to disengage from the linkage groove 5 to achieve no-load protection. When it is necessary for one end of the linkage frame 11 to disengage from the linkage groove 5 with only a smaller force, simply reverse the rotation of the rotating sleeve 2 according to the above steps. After the protection threshold is adjusted appropriately, stop rotating the rotating sleeve 2.This causes the fastening rail 40 to engage with the fastening groove 39, causing the fastening block 16 to rotate between the two corresponding circular blocks 22. Then, the fastening spring 15 resets and pulls the fastening block 16 to slide inward along the fastening rail 40 and the fastening groove 39. The fastening block 16 then causes one side of the fastening wheel 41 to engage between the two corresponding circular blocks 22. Then, the movable plate 13 rotates forward again, causing the movable plate 13 to drive one side of the thrust bearing 36 and the other side of the return block 21 to rotate forward again. At the same time, the movable plate 13 drives the movable plate 13 to rotate again. When the movable groove 14 rotates forward, the return block 21 will again drive the return rod 33 on one side to rotate forward along the return hole 34. The return block 21 will also cooperate with the fixed block 20 to press the return spring 12. When the movable groove 14 rotates to the position corresponding to the limiting plate 19, the movable spring 35 pushes the fastening sleeve 17 to drive the inner slider 38 to slide and reset along the slide groove 37. Then, the fastening sleeve 17 will drive the three limiting plates 19 to slide and reset through the limiting plate 18. When the movable spring 35 is fully reset... At that time, the other two limiting plates 19 just moved to the sides of the movable plate 13 respectively, and then the movable plate 13 was released. Then the return spring 12 pushed the return block 21 to rotate and reset. Then the return block 21 would drive one side of the return rod 33 to rotate and reset along the return hole 34. Then the return block 21 would drive the thrust bearing 36 to rotate and reset again through the movable plate 13, and cause the movable plate 13 to drive the movable groove 14 to rotate and reset to a position that does not correspond to the limiting plate 19 and the limiting plate 18. The rear limiting plate 18, together with two limiting plates 19, restricts the fastening sleeve 17 to one side of the movable plate 13. Combined with the limiting effect of the slider 38 and the sliding groove 37 on the fastening sleeve 17, it prevents the fastening sleeve 17 from moving. Then, the inner wall of the fastening sleeve 17 limits the outer wall of the fastening wheel 41, preventing the fastening wheel 41 and the fastening block 16 from moving outwards. This achieves rotational limitation on the rotating sleeve 2, preventing it from rotating and ensuring the structural stability after the protection threshold adjustment, thus ensuring the stable operation of the mixing process.

[0038] In summary, when using or operating the equipment: First, add the raw materials into the mixing chamber 1, then turn on the motor 25. The motor 25 will drive the linkage sleeve 3 connected to the output end to rotate. The linkage sleeve 3 will drive the inner mixing groove 8 to rotate, thereby driving the mixing block 10, the push block 9, the push spring 6, and the linkage frame 11 to rotate. Then, the linkage frame 11, through its cooperation with the linkage groove 5, will drive the linkage rod 4 to rotate. The linkage rod 4 will then drive the mixing rod 26 and its outer blade 27 to rotate, achieving the mixing of the raw materials. After mixing, the discharged feed can be collected through external equipment. When the protection threshold is triggered... When the stirring rod 26 and the blade encounter resistance exceeding the set threshold, the inner wall of the linkage groove 5 on the outer side of the linkage rod 4 presses against one end of the linkage frame 11. Due to the rounded corner treatment of one end of the linkage frame 11 and the rounded corner design of the linkage groove 5, one end of the linkage frame 11 will slide out from one end of the linkage groove 5. Due to the arc design of the other end of the linkage frame 11 and the special structural design of the mixing block 10, one end of the linkage frame 11 presses down on the mixing block 10, causing the mixing block 10 to slide along the mixing groove 8. Since the push block 9 does not move, the mixing block 10 cooperates with the push block 9 to press against the push spring 6, causing the motor 25 to drive the linkage sleeve 3 and other components to run idle, realizing no-load protection and preventing damage to the motor 25.

[0039] When the protection threshold needs to be adjusted, first rotate the movable plate 13 forward. Then, the movable plate 13 will drive the movable groove 14 to rotate forward, and the movable plate 13 will drive the thrust bearing 36 on one side and the return block 21 installed on the other side to rotate forward. Then, the return block 21 will drive the return rod 33 on one side to rotate forward along the return hole 34. The return block 21 will cooperate with the fixed block 20 to compress the return spring 12. When the return spring 12 is compressed to its limit, the movable groove 14 will rotate to the position corresponding to the limiting plate 19, and then push the fastening sleeve 17. The fastening sleeve 17 will drive the inner slider 38 to slide along the slide groove 37, and the fastening sleeve 17 will drive the limiting plate 18 and the limiting plate 19 on one side to slide, so that the limiting plate As the limiting plate 18 and the limiting plate 19 gradually slide through the movable groove 14, the fastening sleeve 17 and the thrust bearing 36 cooperate to compress the movable spring 35. When the movable spring 35 is compressed to its limit, the limiting plate 19 closest to the fastening sleeve 17 just slides through the movable groove 14 and moves to the other side of the movable plate 13. Then the movable plate 13 is released, and the return spring 12 pushes the return block 21 to rotate and reset. Then the return block 21 drives one side of the return rod 33 to rotate and reset along the return hole 34. The return block 21 also drives the movable groove 14 and the thrust bearing 36 to rotate and reset through the movable plate 13, so that the movable groove 14 rotates and resets to a position that does not correspond to the limiting plate 19. Then the limiting plate 18 and the limiting plate closest to the fastening sleeve 17... 19. The fastening sleeve 17 is limited to one side of the movable plate 13, so that the inner wall of the fastening sleeve 17 no longer limits the outer wall of the fastening wheel 41. Then, the rotating sleeve 2 is rotated in the forward direction. The rotating sleeve 2 drives one side of the fastening rail 40 to rotate in the forward direction. Then, the fastening rail 40 drives the fastening block 16 and the fastening wheel 41 to rotate in the forward direction through the fastening groove 39. This causes the fastening block 16 to drive the fastening wheel 41 to move out from between the two round blocks 22. Then, the fastening wheel 41 will drive the fastening block 16 to slide outward along the fastening rail 40 and the fastening groove 39. Then, the fastening block 16 will drive the fastening spring 15 to stretch outward. Since the outer wall of the threaded sleeve 7 is movably connected to the inner wall of the rotating sleeve 2 through the thread, and the mating block 42 and the mating groove 43 limit the threaded sleeve 7, the threaded sleeve 7 cannot be... Rotate the sleeve 7, and the screw sleeve 7 will synchronously drive the mating block 42 to slide upward along the mating groove 43. Then, the mating block 42 will drive the inner push block 9 to slide along the adjusting groove 8, shortening the distance between the push block 9 and the adjusting block 10. This causes the push spring 6 to be compressed to a certain extent, increasing the thrust exerted by the push spring 6 on the adjusting block 10. Consequently, the thrust exerted by the adjusting block 10 on the linkage frame 11 increases, requiring one end of the linkage frame 11 to withstand greater force to disengage from the linkage groove 5 and achieve no-load protection. When it is necessary for one end of the linkage frame 11 to disengage from the linkage groove 5 with only less force, simply reverse the rotation of the rotating sleeve 2 according to the above steps. After the protection threshold is adjusted appropriately, stop rotating the rotating sleeve 2.This causes the fastening rail 40 to engage with the fastening groove 39, causing the fastening block 16 to rotate between the two corresponding circular blocks 22. Then, the fastening spring 15 resets and pulls the fastening block 16 to slide inward along the fastening rail 40 and the fastening groove 39. The fastening block 16 then causes one side of the fastening wheel 41 to engage between the two corresponding circular blocks 22. Then, the movable plate 13 rotates forward again, causing the movable plate 13 to drive one side of the thrust bearing 36 and the other side of the return block 21 to rotate forward again. At the same time, the movable plate 13 drives the movable plate 13 to rotate again. When the movable groove 14 rotates forward, the return block 21 will again drive the return rod 33 on one side to rotate forward along the return hole 34. The return block 21 will also cooperate with the fixed block 20 to press the return spring 12. When the movable groove 14 rotates to the position corresponding to the limiting plate 19, the movable spring 35 pushes the fastening sleeve 17 to drive the inner slider 38 to slide and reset along the slide groove 37. Then, the fastening sleeve 17 will drive the three limiting plates 19 to slide and reset through the limiting plate 18. When the movable spring 35 is fully reset... At that time, the other two limiting plates 19 just moved to the sides of the movable plate 13 respectively, and then the movable plate 13 was released. Then the return spring 12 pushed the return block 21 to rotate and reset. Then the return block 21 would drive one side of the return rod 33 to rotate and reset along the return hole 34. Then the return block 21 would drive the thrust bearing 36 to rotate and reset again through the movable plate 13, and cause the movable plate 13 to drive the movable groove 14 to rotate and reset to a position that does not correspond to the limiting plate 19 and the limiting plate 18. The rear limiting plate 18, together with two limiting plates 19, restricts the fastening sleeve 17 to one side of the movable plate 13. Combined with the limiting effect of the slider 38 and the sliding groove 37 on the fastening sleeve 17, it prevents the fastening sleeve 17 from moving. Then, the inner wall of the fastening sleeve 17 limits the outer wall of the fastening wheel 41, preventing the fastening wheel 41 and the fastening block 16 from moving outwards. This achieves rotational limitation on the rotating sleeve 2, preventing it from rotating and ensuring the structural stability after the protection threshold adjustment, thus ensuring the stable operation of the mixing process.
