Description

Technical Field

[0001] The present application relates to the field of powder mixing and stirring equipment, and in particular to a plowshare mixer with a large door structure. Background Art

[0002] The coulter mixer is a new and efficient split mixing equipment. It can be divided into stainless steel coulter mixer and carbon steel coulter mixer according to the different coulter materials. It can be divided into horizontal coulter mixer and multifunctional coulter mixer according to the overall structure type. The coulter inside the coulter mixer rotates with the main shaft, causing the material to move radially and circumferentially along the cylinder wall, and the material is continuously dispersed and broken, reaching a uniform mixing state in a short time.

[0003] In the related art, a horizontal plowshare mixer generally includes a stirring kettle body and a stirring assembly located in the stirring kettle body. The stirring assembly is driven by a motor. The stirring kettle body is generally supported by a bracket and horizontally erected on the ground. A feed inlet is provided at the top of the side of the stirring kettle body, and a discharge outlet is provided at the bottom of the side of the stirring kettle body. There are generally multiple discharge outlets arranged in a row and provided with a flip-type valve. When the material needs to be discharged after the mixing is completed, the cylinder is driven by the PLC controller to open the valve to achieve the discharge.

[0004] With regard to the above-mentioned related technologies, the inventors believe that in actual use, there are gaps between multiple discharge ports. When the valve at the discharge port is opened, part of the material will remain on the inner wall of the mixing tank between two adjacent discharge ports, resulting in incomplete discharge. It is also necessary to manually enter the mixing tank to manually discharge the material, which is more troublesome. Summary of the invention

[0005] In order to solve the problem of incomplete material discharge of the existing plowshare mixer, the present application provides a plowshare mixer with a large door structure.

[0006] The present application provides a plowshare mixer with a large door structure, which adopts the following technical solutions:

[0007] A plowshare mixer with a large opening structure comprises a stirring kettle body, the axis of the stirring kettle body is arranged horizontally, a feed port is arranged on the side of the side surface of the stirring kettle body away from the ground, a plowshare stirring assembly is arranged in the stirring kettle body, the plowshare stirring assembly is connected to a driving motor, a discharge port is arranged on the side surface of the stirring kettle body close to the ground, the discharge port is opened along the axis of the stirring kettle body, and the two ends of the length square of the discharge port are respectively connected to the two end faces of the stirring kettle body, a material blocking door is arranged at the discharge port, and the material blocking door is connected to a driving assembly for realizing the opening and closing of the discharge port.

[0008] By adopting the above technical scheme, unlike the discharge port in the related art, the discharge port in the present application is opened along the axis of the mixing kettle body. When the material blocking door is opened, all the materials in the mixing kettle body flow out from the discharge port to achieve complete unloading of the mixing kettle body. There is no need to use manual secondary unloading steps, which effectively improves the discharge efficiency of the plowshare mixer and reduces the use of manpower.

[0009] Preferably, the two ends of the stirring kettle body are respectively sealed and connected with a primary mounting plate and a secondary mounting plate, the driving assembly comprises a primary transmission shaft and a primary driving cylinder installed on the surface of the primary mounting plate, the two ends of the primary transmission shaft are rotatably connected with the primary mounting plate and the secondary mounting plate respectively through bearing seats, a primary cantilever is connected between the output end of the primary driving cylinder and the end of the primary transmission shaft, one end of the primary cantilever is connected to the end of the primary transmission shaft, and the circumferential position of the primary cantilever on the primary transmission shaft is fixed, the other end of the primary cantilever is hinged to the output end of the primary driving cylinder, a primary mounting seat is provided on the surface of the primary mounting plate, the base of the primary driving cylinder is hinged to the primary mounting seat, a plurality of primary connecting rods are fixedly connected to the primary transmission shaft, and the end of the primary connecting rod away from the primary transmission shaft is fixedly connected to the surface of the material blocking door.

[0010] By adopting the above technical solution, when the first-stage driving cylinder is extended or retracted, the first-stage transmission shaft is caused to rotate along its own axis through the first-stage cantilever, and then the first-stage transmission shaft drives the material blocking door to move away from or close to the discharge port through the first-stage connecting rod, thereby realizing the opening and closing of the discharge port.

[0011] Preferably, a reinforcement component is provided on the stirring kettle body, and a plurality of the reinforcement components are arranged along the length direction of the primary transmission shaft. The reinforcement component includes a reinforcement arm, one end of the reinforcement arm is fixedly connected to the outer surface of the stirring kettle body, and the other end of the reinforcement arm forms an arc-shaped bending and fitting section, and the surface of the primary transmission shaft abuts against the curved inner side of the bending and fitting section.

[0012] By adopting the above technical solution, the setting of the reinforcement component plays a supporting role for the primary transmission shaft. First, when the material blocking door is closed, the material in the mixing kettle body will be affected by gravity and will gather on the inner surface of the material blocking door, so that the primary rotating shaft needs to bear the pressure perpendicular to the axial direction. By setting the reinforcement component, it can play a supporting role for the transmission shaft; second, due to the existence of installation and manufacturing errors, when the material blocking door is opened or closed, the primary transmission shaft may produce radial vibration, and the setting of the reinforcement component can effectively reduce the vibration; third, the whole mixing kettle body will produce thermal expansion and contraction due to the temperature of the powder itself, resulting in an axial force inside the primary transmission shaft. When the axial pressure is generated inside the primary transmission shaft, the primary transmission shaft will tend to be bent. The setting of the reinforcement component can effectively reduce the possibility of bending of the primary transmission shaft. The arc-shaped bending and fitting section can effectively increase the contact area between the reinforcement arm and the primary transmission shaft, thereby effectively improving the support effect of the reinforcement arm on the primary transmission shaft.

[0013] Preferably, a bonding plate is further provided on the inner side of the bent bonding section, and the bonding plate is a curved surface. When the primary transmission shaft rotates along its own axis, the surface of the primary transmission shaft always fits with the surface of the bonding plate.

[0014] By adopting the above technical solution, the provision of the bonding plate can further increase the contact area between the reinforcement component and the primary transmission shaft, and further improve the overall structural stability when the primary transmission shaft rotates.

[0015] Preferably, a wear-resistant sheet is bonded to the surface of the bonding plate close to the primary transmission shaft, and the material of the wear-resistant sheet is tin bronze.

[0016] By adopting the above technical solution, when the material blocking door is opened and closed, mutual friction continues to occur between the surface of the primary transmission shaft and the bonding plate. Tin bronze itself has good anti-friction performance and corrosion resistance, and has high strength, and can have a long service life under long-term friction.

[0017] Preferably, the stirring kettle body is also provided with a leak-proof component, which includes a secondary transmission shaft and a secondary driving cylinder installed on the surface of the primary mounting plate, both ends of the secondary transmission shaft are rotatably connected to the primary mounting plate and the secondary mounting plate respectively through bearing seats, a secondary cantilever is connected between the output end of the secondary driving cylinder and the end of the secondary transmission shaft, one end of the secondary cantilever is connected to the end of the secondary transmission shaft, and the circumferential position of the secondary cantilever on the secondary transmission shaft is fixed, the other end of the secondary cantilever is hinged to the output end of the secondary driving cylinder, a secondary mounting seat is provided on the surface of the primary mounting plate, the base of the secondary driving cylinder is hinged to the secondary mounting seat, a number of secondary connecting rods are fixedly connected to the secondary transmission shaft, and when the material blocking door is closed, the end of the secondary connecting rod away from the secondary transmission shaft abuts against the surface of the material blocking door.

[0018] By adopting the above-mentioned technical scheme, in order to improve the stability and sealing of the connection between the material blocking door and the mixing kettle body and reduce the occurrence of material leakage, when the material blocking door is closed, the secondary driving cylinder is started to rotate the secondary transmission shaft, and the end of the secondary connecting rod is moved toward the surface of the material blocking door, and the end of the secondary connecting rod is abutted against the material blocking door, so that the secondary connecting rod supports the material blocking door, thereby reducing the occurrence of powder leakage due to excessive powder in the mixing kettle body or excessive internal gas pressure.

[0019] Preferably, a self-locking component is provided at the secondary mounting plate, and the self-locking component includes a three-stage driving cylinder installed on the surface of the secondary mounting plate, the end of the first-stage transmission shaft away from the first-stage mounting plate is connected to the three-stage cantilever, the end of the three-stage cantilever is hinged with a first-stage self-locking rod, and the end of the first-stage self-locking rod away from the three-stage cantilever is hinged with a second-stage self-locking rod, a three-stage mounting seat and a four-stage mounting seat are fixedly provided on the secondary mounting plate, the three-stage mounting seat is hinged to the end of the second-stage self-locking rod away from the first-stage self-locking rod, the base of the three-stage driving cylinder is hinged to the four-stage mounting seat, the output end of the three-stage driving cylinder is hinged to the rod body of the first-stage self-locking rod or the rod body of the second-stage self-locking rod, and when the material blocking door is closed, the axis of the first-stage self-locking rod coincides with the axis of the second-stage self-locking rod.

[0020] By adopting the above technical solution, when the plow blade mixer suddenly loses power or gas during operation, it is difficult for the primary drive cylinder and the secondary drive cylinder to continue to provide sufficient supporting force. Under the action of the gravity of the powder and the gravity of the material blocking door itself, it is easy to cause the material blocking door and the mixing kettle body to separate from each other, thereby causing large-scale material leakage. Therefore, a self-locking component is set. When the material blocking door is closed, the primary self-locking rod and the secondary self-locking rod are connected in a straight line. When the position of the material blocking door tends to change, the primary transmission shaft tends to rotate, so that the tertiary cantilever tends to move. The end of the tertiary cantilever away from the primary transmission shaft exerts a deviation force on the primary self-locking rod. The direction of the deviation force is perpendicular to the line connecting the end of the tertiary cantilever and the axis of the primary transmission shaft. The deviation force can be orthogonally decomposed into two components along the direction of the axis of the primary self-locking rod. Among them, the component parallel to the direction of the primary self-locking rod will not affect the position of the primary self-locking rod and the secondary self-locking rod, while the vertical component will not affect the position of the primary self-locking rod and the secondary self-locking rod. The component perpendicular to the direction of the first-level self-locking rod will cause the first-level self-locking rod to have a tendency to change position, but the absolute value of this component is smaller than the absolute value of the deviation force, so its influence on the third-level driving cylinder is limited. By controlling the placement angle of the first-level self-locking rod, the absolute value of the component of the deviation force perpendicular to the direction of the first-level self-locking rod can be reduced as much as possible, so that even in the case of power or gas failure, the third-level driving cylinder can still offset the influence of this component, thereby maintaining the stability of the overall structure of the first-level transmission shaft, and not easily rotating, thereby reducing the possibility of separation between the material blocking door and the mixing kettle body.

[0021] Preferably, the inner wall surfaces at the edges of the discharge port are inclined toward the interior of the stirring kettle body, and when the material blocking door is closed, the side surfaces of the outer edges of the material blocking door fit with the inner wall surfaces of the discharge port.

[0022] By adopting the above technical solution, the inner wall of the discharge port is inclined, which can facilitate the alignment between the blocking door and the discharge port when it is closed, and on the other hand, increase the sealing area between the blocking door and the discharge port, thereby further reducing the possibility of powder leakage.

[0023] Preferably, a sealing strip mounting piece is provided at the surface edge of the material blocking door located on the outer side of the mixing kettle body, and both sides of the sealing strip mounting piece are bent to form a mounting groove with a square cross-section, and the opening of the mounting groove faces the connection between the material blocking door and the mixing kettle body. A sealing strip is fixedly connected in the mounting groove, and the thickness of the sealing strip is greater than the depth of the mounting groove.

[0024] By adopting the above technical solution, the sealing strip mounting plate is fixedly connected to the material blocking door and provides an installation space for the sealing strip; when the material blocking door is closed, the sealing strip in the mounting groove seals the gap between the material blocking door and the discharge port; the thickness of the sealing strip is greater than the depth of the mounting groove, and the sealing strip is squeezed when in contact with the edge of the discharge port, which can effectively improve the sealing effect of the sealing strip.

[0025] In summary, the present application includes at least one of the following beneficial technical effects:

[0026] 1. The setting of the discharge port and the material blocking door can make the plowshare mixer discharge more completely and improve the discharge efficiency;

[0027] 2. Through the setting of the driving component and the reinforcement component, the opening and closing of the material blocking door can be realized and the rotation stability of the primary transmission shaft can be improved;

[0028] 3. Through the setting of the leak-proof component and the self-locking component, the powder in the stirring tank body can be prevented from leaking out. BRIEF DESCRIPTION OF THE DRAWINGS

The discharge ports 17 are generally arranged in a plurality and are provided with a flip-top valve.

[0038] The present application embodiment discloses a plowshare mixer with a large door structure. Figure 1 A plowshare mixer with a large door structure includes a mixing kettle body 1. The plowshare mixer in the present application is horizontal, so the axis of the mixing kettle body 1 is arranged horizontally. A funnel-shaped feed port 11 is arranged on the top of the mixing kettle body 1, and a primary mounting plate 15 and a secondary mounting plate 16 are respectively arranged at both ends of the length direction of the mixing kettle body 1. In the present embodiment, a support plate 18 is also connected between the primary mounting plate 15 and the secondary mounting plate 16. Two support plates 18 are provided and are respectively arranged on both sides of the mixing kettle body 1. A plurality of inspection ports 181 are opened on the surface of the support plate 18, and an inspection door 182 is hingedly arranged at the inspection port 181. The arrangement of the inspection port 181 facilitates the staff to enter the interior of the plowshare mixer for inspection.

[0039] Reference Figure 2 and Figure 3A plowshare stirring assembly 12 is arranged inside the stirring kettle body 1. The plowshare stirring assembly 12 includes a main shaft 121. The main shaft 121 is provided with a plurality of stirring blades 122 extending radially along the main shaft 121. A plowshare-shaped stirring head 123 is arranged at the end of the stirring blade 122. The stirring head 123 is attached to the inner wall of the stirring kettle body 1. The main shaft 121 is connected to a driving motor 13 (refer to Figure 1 ), in this embodiment, the driving motor 13 is fixedly mounted on the primary mounting plate 15. A discharge port 17 is provided on the side of the side surface of the mixing tank body 1 close to the ground, and the discharge port 17 is opened along the axis of the mixing tank body 1, and the two ends of the length of the discharge port 17 are respectively connected to the two end surfaces of the mixing tank body 1. In this embodiment, the discharge port 17 is located between the two support plates 18.

[0040] Reference Figure 1 and Figure 3 The large door structure in the present application includes a material blocking door 14 arranged at the discharge port 17, a driving assembly 2 for realizing the opening and closing of the discharge port 17, and a leak-proof assembly 4 for reducing leakage. Different from the discharge port 17 in the related art, the discharge port 17 in the present application is opened along the axis of the mixing kettle body 1. When the material blocking door 14 is opened, all the materials in the mixing kettle body 1 flow out from the discharge port 17 to realize the complete discharge of the mixing kettle body 1, and no manual secondary discharge step is required, which effectively improves the discharge efficiency of the plowshare mixer and reduces the use of manpower.

[0041] Reference Figure 1 and Figure 3 The driving assembly 2 includes a primary transmission shaft 21 and a primary driving cylinder 22 mounted on the surface of the primary mounting plate 15. The two ends of the primary transmission shaft 21 are rotatably connected to the primary mounting plate 15 and the secondary mounting plate 16 through bearing seats respectively. A primary cantilever 23 is connected between the output end of the primary driving cylinder 22 and the end of the primary transmission shaft 21. One end of the primary cantilever 23 is connected to the end of the primary transmission shaft 21, and the circumferential position of the primary cantilever 23 on the primary transmission shaft 21 is fixed. The other end of the primary cantilever 23 is hinged to the output end of the primary driving cylinder 22. A primary mounting seat 24 is provided on the surface of the primary mounting plate 15. The base of the primary driving cylinder 22 is hinged to the primary mounting seat 24. A plurality of primary connecting rods 25 are fixedly connected to the primary transmission shaft 21. The end of the primary connecting rod 25 away from the primary transmission shaft 21 is fixedly connected to the surface of the material blocking door 14.

[0042] Reference Figure 1 and Figure 3The leakage-proof component 4 includes a secondary transmission shaft 41 and a secondary driving cylinder 42 mounted on the surface of the primary mounting plate 15. The two ends of the secondary transmission shaft 41 are rotatably connected to the primary mounting plate 15 and the secondary mounting plate 16 respectively through bearing seats. A secondary cantilever 43 is connected between the output end of the secondary driving cylinder 42 and the end of the secondary transmission shaft 41. One end of the secondary cantilever 43 is connected to the end of the secondary transmission shaft 41, and the circumferential position of the secondary cantilever 43 on the secondary transmission shaft 41 is fixed, and the other end of the secondary cantilever 43 is hinged to the output end of the secondary driving cylinder 42. A secondary mounting seat 44 is provided on the surface of the primary mounting plate 15, and the base of the secondary driving cylinder 42 is hinged to the secondary mounting seat 44. A plurality of secondary connecting rods 45 are fixedly connected to the secondary transmission shaft 41. When the material blocking door 14 is closed, the end of the secondary connecting rod 45 away from the secondary transmission shaft 41 abuts against the surface of the material blocking door 14. In this embodiment, the end of the secondary connecting rod 45 away from the secondary transmission shaft 41 is rotatably connected to a roller 451 , and the circumferential surface of the roller 451 is in contact with the surface of the material blocking door 14 .

[0043] Reference Figure 3 and Figure 4 The inner wall surface at each edge of the discharge port 17 is inclined toward the inside of the mixing kettle body 1, and when the blocking door 14 is closed, the side surface of the outer edge of the blocking door 14 fits with the inner wall surface of the discharge port 17. The inclined inner wall surface of the discharge port 17 can facilitate the alignment between the blocking door 14 and the discharge port 17 when the blocking door 14 is closed, and can increase the sealing area between the blocking door 14 and the discharge port 17. In order to further reduce the possibility of powder leakage from the mixing kettle body 1, a sealing strip installation piece 141 is installed at the outer edge of the material blocking door 14. The two sides of the sealing strip installation piece 141 are bent to form a square-section installation groove 142. The opening of the installation groove 142 faces the connection between the material blocking door 14 and the mixing kettle body 1. A sealing strip 143 is fixedly connected in the installation groove 142. The thickness of the sealing strip 143 is greater than the depth of the installation groove 142. When the material blocking door 14 is closed, the sealing strip 143 in the installation groove 142 blocks the gap between the material blocking door 14 and the discharge port 17. The sealing strip installation piece 141 is fixedly connected to the material blocking door 14 and provides an installation space for the sealing strip 143.

[0044] Reference Figure 5 and Figure 6A self-locking component 5 is provided at the secondary mounting plate 16, and the self-locking component 5 includes a three-stage driving cylinder 51 installed on the surface of the secondary mounting plate 16, and the end of the primary transmission shaft 21 away from the primary mounting plate 15 is connected to the three-stage cantilever 52, and the end of the three-stage cantilever 52 is hinged with a primary self-locking rod 53, and the end of the first self-locking rod 53 away from the three-stage cantilever 52 is hinged with a secondary self-locking rod 54, and a three-stage mounting seat 55 and a four-stage mounting seat 56 are fixedly provided on the secondary mounting plate 16, and the three-stage mounting seat 55 is hinged to the end of the secondary self-locking rod 54 away from the first self-locking rod 53, and the base of the three-stage driving cylinder 51 is hinged to the four-stage mounting seat 56, and the output end of the three-stage driving cylinder 51 is hinged to the rod body of the first self-locking rod 53 or the rod body of the second self-locking rod 54. When the material blocking door 14 is closed, the axis of the first self-locking rod 53 coincides with the axis of the second self-locking rod 54.

[0045] Reference Figure 3 A reinforcement component 3 is provided on the stirring kettle body 1. The setting of the reinforcement component 3 supports the primary transmission shaft 21. Several reinforcement components 3 are arranged along the length direction of the primary transmission shaft 21. The reinforcement component 3 includes a reinforcement arm 31. One end of the reinforcement arm 31 is fixedly connected to the outer surface of the stirring kettle body 1, and the other end of the reinforcement arm 31 forms an arc-shaped bending and fitting section 32. In this embodiment, two reinforcement arms 31 are distributed along the length direction of the primary transmission shaft 21 in a reinforcement component 3, and a fitting plate 33 is fixedly connected between the two reinforcement arms 31. The fitting plate 33 is a curved surface and is arranged on the inner side of the bending and fitting section 32. A wear-resistant sheet 34 made of tin bronze is fitted on the surface of the fitting plate 33 close to the primary transmission shaft 21. When the primary transmission shaft 21 rotates along its own axis, the surface of the primary transmission shaft 21 is always fitted with the surface of the wear-resistant sheet 34. The arrangement of the bonding plate 33 can further increase the contact area between the reinforcement component 3 and the primary transmission shaft 21. The wear-resistant sheet 34 made of tin bronze itself has good anti-friction performance and corrosion resistance, and can have a long service life under long-term friction. The reinforcement component 3 can also be arranged at the secondary transmission shaft 41 and play a supporting role for the secondary transmission shaft 41.

[0046] The implementation principle of a plowshare mixer with a large door structure in the embodiment of the present application is:

[0047] When feeding into the plow blade mixer, first control the first-stage drive cylinder 22 to contract and the third-stage drive cylinder 51 to contract synchronously, and make the first-stage transmission shaft 21 rotate along its own axis through the first-stage cantilever 23, and then the first-stage transmission shaft 21 drives the material blocking door 14 to move toward the discharge port 17 through the first-stage connecting rod 25, until the outer edge of the material blocking door 14 is completely in contact with the inner edge of the discharge port 17, and then control the second-stage drive cylinder 42 to contract, so that the second-stage transmission shaft 41 drives the end of the second-stage connecting rod 45 to move toward the material blocking door 14, and make the surface of the roller 451 at the end of the second-stage connecting rod 45 abut against the surface of the material blocking door 14, thereby supporting the material blocking door 14 and reducing the leakage that may occur during the powder mixing process. Then the staff feeds the material from the feed port 11 and turns on the drive motor 13 to stir the powder in the mixing tank body 1.

[0048] After the powder mixing is completed, it is necessary to discharge the material. At this time, the secondary driving cylinder 42 is first controlled to extend so that the end of the secondary connecting rod 45 is separated from the material blocking door 14, and then the primary driving cylinder 22 is controlled to contract and the tertiary driving cylinder 51 is synchronously extended so that the material blocking door 14 is separated from the material discharging port 17 to achieve the material discharging. When the material blocking door 14 is opened, all the materials in the mixing kettle body 1 flow out from the material discharging port 17 to achieve the complete discharge of the mixing kettle body 1, and there is no need to use the manual secondary discharging step, which effectively improves the discharging efficiency of this type of plowshare mixer.

[0049] During the rotation of the primary transmission shaft 21 and the secondary transmission shaft 41, the reinforcement component 3 supports the primary transmission shaft 21 and the secondary transmission shaft 41. Taking the primary transmission shaft 21 as an example, on the one hand, when the material blocking door 14 is closed, the material in the mixing kettle body 1 will be affected by gravity and will gather on the inner surface of the material blocking door 14, so that the primary rotating shaft needs to bear the pressure perpendicular to the axial direction. By setting the reinforcement component 3, the primary transmission shaft and the secondary transmission shaft can be supported; on the other hand, due to the existence of installation and manufacturing errors, when the material blocking door 14 is opened or closed, the primary transmission shaft 21 may produce radial vibration, and the setting of the reinforcement component 3 can effectively reduce the vibration; on the third hand, the mixing kettle body 1 as a whole will produce thermal expansion and contraction due to the temperature of the powder itself, resulting in an axial force inside the primary transmission shaft 21. When the axial pressure is generated inside the primary transmission shaft 21, the primary transmission shaft 21 will tend to be bent. The setting of the reinforcement component 3 can effectively reduce the possibility of bending of the primary transmission shaft 21.

[0050] When the plowshare mixer suddenly loses power or gas during operation, it is difficult for the first-stage drive cylinder 22 and the second-stage drive cylinder 42 to continue to provide sufficient supporting force. Under the action of the gravity of the powder and the gravity of the material blocking door 14 itself, the material blocking door 14 and the mixing kettle body 1 are easily separated from each other, resulting in large-scale leakage of materials.

[0051] In order to reduce the occurrence of this situation, a self-locking component 5 is provided. When the material blocking door 14 is closed, the primary self-locking rod 53 and the secondary self-locking rod 54 are connected in a straight line. When the position of the material blocking door 14 tends to change, the primary transmission shaft 21 tends to rotate, thereby making the tertiary cantilever 52 tend to move. The end of the tertiary cantilever 52 away from the primary transmission shaft 21 exerts a deviation force on the primary self-locking rod 53. The direction of the deviation force is perpendicular to the line connecting the end of the tertiary cantilever 52 and the axis of the primary transmission shaft 21. The deviation force can be orthogonally decomposed into two components along the direction of the axis of the primary self-locking rod 53, wherein the component parallel to the axis of the primary self-locking rod 53 will not affect the primary self-locking rod 53 and the secondary self-locking rod. The position of the locking rod 54 is affected, and the component perpendicular to the direction of the primary self-locking rod 53 will make the primary self-locking rod 53 have a tendency to change position, but the absolute value of this component is smaller than the absolute value of the deviation force, so its influence on the three-stage driving cylinder 51 is limited. By controlling the placement angle of the primary self-locking rod 53, the absolute value of the component of the deviation force perpendicular to the direction of the primary self-locking rod 53 can be reduced as much as possible, so that even in the case of power failure or gas failure, the three-stage driving cylinder 51 can still offset the influence of this component, thereby maintaining the stability of the overall structure of the primary transmission shaft 21, and not easily rotating, thereby reducing the possibility of separation between the material blocking door 14 and the stirring kettle body 1. In the specific implementation process, when the material blocking door 14 is closed, it is best for the axial direction of the primary self-locking rod 53 to be parallel to the direction of the deviation force, and the self-locking effect is the best.
