The embodiments described below by referring to the accompanying drawings are exemplary and are intended to explain the present invention and should not be construed as a limitation of the present invention.

[0039] Embodiment 1

[0041] The spiral stirring mechanism 2 includes a motor assembly 21. The motor of the motor assembly 21 is slidably connected to the bracket. The front of the motor is fixedly connected to the back of the box body 11 through a spring. The motor assembly 21 is fixedly connected to the back of the box body 11 through the bracket. The motor of the motor assembly 21 is electrically connected to the electric control cabinet 5 through a wire. A hollow spiral shaft 22 is rotatably connected inside the box body 11. The hollow spiral shaft 22 is made of stainless steel. A spiral blade is fixedly connected to the surface of the hollow spiral shaft 22. The hollow spiral shaft 22 is used to mix and stir the feed. The hollow spiral shaft 22 includes a spiral shaft main body 221. The inside of the spiral shaft main body 221 is a hollow structure. A heat insulation sleeve 224 is fixedly connected inside the spiral shaft main body 221. The heat insulation sleeve 224 is located on the back of the spiral shaft main body 221. The inside of the heat insulation sleeve 224 is fixedly connected to the motor shaft of the motor assembly 21. A sliding tube 222 is fixedly connected to the front of the spiral shaft main body 221, which is used to assist the hollow spiral shaft 22 to achieve lateral sliding. The sliding tube 222 is slidably connected to the circular through hole of the plate body 121 and is rotatably connected to the circular through hole of the plate body 121. A sliding wheel 223 is rotatably connected to the front of the spiral shaft main body 221. The number of sliding wheels 223 is two and they are symmetrically distributed on the front of the spiral shaft main body 221. The sliding wheels 223 are used to cooperate with the semi-circular convex blocks 122 to jointly achieve the periodic sliding of the hollow spiral shaft 22;

[0042] A linkage cam 23 is slidably connected to the front of the sliding tube 222. The linkage cam 23 is located on the front of the plate body 121. A rubber layer is covered on the surface of the linkage cam 23. The linkage cam 23 is used to generate vibration and cooperate with the operation of the linkage vibration mechanism 3;

[0043] An axial heating mechanism 4 is fixedly connected to the front of the box body 11, which is used to heat and keep warm the feed, promote the mixing of the feed, and reduce the adhesion of the feed inside the device. An electric control cabinet 5 is fixedly connected to the front of the axial heating mechanism 4.

[0044] During use, before starting the device, place the feed collection mechanism at the bottom of the discharge port of the box body 11. First, start the entire device through the electric control cabinet 5. After the electric control cabinet 5 is started, the motor assembly 21 and the axial heating mechanism 4 are started under the control of the electric control cabinet 5. The motor assembly 21 drives the hollow spiral shaft 22 and the linkage cam 23 to rotate. The axial heating mechanism 4 generates heat to heat the inside of the device. After the device is started, pour the feed to be mixed into the device from the feed port at the top of the box body 11 at the same time. All the feed enters the inside of the box body 11 from the feed port. All the feed spirally advances under the push of the spiral blade of the spiral shaft main body 221 and tumbles and mixes during the advancing process until the feed reaches the discharge port at the bottom of the box body 11 and falls into the feed collection mechanism to complete the mixing and conveying;

[0045] During the conveying process, the main body 221 of the spiral shaft drives the sliding wheel 223 to rotate through the sliding pipe 222. The rotation of the sliding wheel 223 generates vibrations, which are transmitted to the main body 221 of the spiral shaft through the sliding pipe 222 and then transmitted to the feed by the spiral blades of the main body 221 of the spiral shaft. Under the action of the vibrations, the mobility of the feed is further improved, promoting the mixing between different feeds. At the same time, the feed adhering to the inner surface of the device is loosened and shed, preventing the feed from adhering to the inside of the device for a long time. When the main body 221 of the spiral shaft rotates, when the sliding wheel 223 passes over the surface of the semi-circular convex block 122, the sliding wheel 223 slides along the surface of the semi-circular convex block 122 under the action of the semi-circular convex block 122, thereby pushing the sliding pipe 222, the main body 221 of the spiral shaft, and the motor of the motor assembly 21 to slide simultaneously. During the sliding, the motor stretches the spring. When the sliding wheel 223 disengages from the surface of the semi-circular convex block 122, the motor of the motor assembly 21 and the hollow spiral shaft 22 reset under the action of the spring. During the sliding process of the hollow spiral shaft 22, the main body 221 of the spiral shaft laterally shakes the feed inside the device repeatedly, promoting the mixing of the feed and reducing the adhesion of the feed inside the box 11 through slight scraping and lateral vibrations.

[0046] Embodiment Two

[0047] Please refer to Figure 1-11 , based on Embodiment One, the present invention provides a technical solution: The linkage vibration mechanism 3 includes:

[0048] A sliding box 31, which is fixedly connected to the front of the box 11. A rectangular blind hole is provided on the left side of the sliding box 31, and a rectangular through hole is provided on the top of the sliding box 31. The number of sliding boxes 31 is two, and they are symmetrically distributed on the front of the box 11. The sliding box 31 is the operating basis of the entire linkage vibration mechanism 3;

[0049] A vibration frame 32, which is slidably connected to the inside of the sliding box 31. The vibration frame 32 is located on the top of the box 11. The vibration frame 32 includes a linkage contact plate 321, which is used to cooperate with the linkage cam 23 to achieve periodic impacts on the top of the box 11. The linkage contact plate 321 is slidably connected to the inside of the rectangular blind hole of the sliding box 31. The top of the linkage contact plate 321 is fixedly connected to the top of the inner wall of the sliding box 31 through a spring. The number of linkage contact plates 321 is two, and the lateral length of the linkage contact plate 321 on the left is less than the lateral length of the linkage contact plate 321 on the right. The vibration frame 32 is used to cooperate with the spiral stirring mechanism 2 to achieve periodic impacts on the top of the box 11 to generate vibrations;

[0050] A distance sensor 33 is fixedly connected to the front of the box 11. The distance sensor 33 is located on the top of the right linkage contact plate 321. The distance sensor 33 is used to detect the change in the distance of the vibration frame 32. The vibration frame 32 is electrically connected to the electric control cabinet 5 through a wire.

[0051] In use, during the operation of the spiral stirring mechanism 2 in the first embodiment, when the linkage cam 23 rotates to the bottom of the linkage contact plate 321, the surface of the linkage cam 23 contacts the bottom of the linkage contact plate 321, pushing the linkage contact plate 321 to slide upward. The linkage contact plate 321 slides upward along the inside of the sliding box 31 under the action of the linkage cam 23, while squeezing the spring inside the sliding box 31. The linkage contact plate 321 drives the frame body 322 to slide upward through the round rod. The rectangular rod at the bottom of the frame body 322 slides upward along the sliding sleeve 324. At the same time, the frame body 322 drives the vibration hammer rod 323 to slide upward. As the linkage cam 23 continues to rotate, when the linkage cam 23 disengages from the linkage contact plate 321, the linkage contact plate 321 starts to reset under the action of the spring and gravity. The linkage contact plate 321 drives the frame body 322 to reset through the round rod, and the frame body 322 drives the vibration hammer rod 323 to reset. After the vibration hammer rod 323 resets, the bottom surface of its bottom impacts the top surface of the box body 11, thereby generating vibration. The vibration is transmitted from the top surface of the box body 11 to the inside of the box body 11, further loosening the feed adhered to the inside of the box body 11. As the linkage cam 23 continues to rotate, the process of the vibration frame 32 impacting the surface of the box body 11 occurs periodically, thereby generating periodic vibration through the impact, so as to realize the loosening and dredging of the adhered feed inside the device.

[0052] Embodiment Three

[0053] Please refer to Figure 1-12 , based on the first and second embodiments, the present invention provides a technical solution: The axial heating mechanism 4 includes a T-shaped bracket 41, and the T-shaped bracket 41 is fixedly connected to the front of the box body 11. The T-shaped bracket 41 is located at the bottom of the sliding box 31 and is the installation basis of the entire axial heating mechanism 4. An electric control cabinet 5 is fixedly connected to the front of the T-shaped bracket 41. A heating tube 42 is rotatably connected to the back of the T-shaped bracket 41. The heating tube 42 is internally provided with a heating wire, and the heating wire is used to generate heat to heat the feed inside the device after being energized. The heating tube 42 is electrically connected to the electric control cabinet 5 and is used to generate heat to heat the feed. The surface of the heating tube 42 is located inside the hollow spiral shaft 22, and the back of the heating tube 42 is rotatably connected to the inside of the hollow spiral shaft 22 through a bearing. A pressure sensor group 6 is embedded at the bottom of the inner wall of the box body 11, and the pressure sensor group 6 is electrically connected to the electric control cabinet 5 through a wire.

[0054] When in use, after the device is started, the electric heating tube 42 is stationary relative to the box body 11, and the electric heating tube 42 moves relative to the hollow spiral shaft 22. After the electric control cabinet 5 is started, the electric heating tube 42 is energized. After the electric heating tube 42 is energized, the electric heating wire generates heat, and the heat is transferred to the surface of the spiral shaft body 221 through the electric heating tube 42, and then transferred to the surface of the spiral blade, and finally transferred to the surface of the feed through the spiral blade. As the temperature inside the box body 11 rises, the feed inside the box body 11 cooperates with the stirring and transportation of the hollow spiral shaft 22 in a high temperature environment to accelerate and mix the process. At the same time, the fluid feed attached to the inner wall of the box body 11 and the surface of the hollow spiral shaft 22 flows under the action of high temperature, and is driven by other feeds to separate from the surface inside the device, thereby reducing the adhesion and blockage of the feed inside the device.

[0055] During the operation of the device, the pressure sensor group 6 monitors the pressure data inside the device in real time and transmits it back to the electrical control cabinet 5. When the pressure data returned by the pressure sensor group 6 exceeds the normal range, the electrical control cabinet 5 determines that a blockage has occurred inside the device, thereby increasing the speed of the motor of the motor assembly 21 and the current of the electric heating tube 42, thereby reducing the blockage through higher speed torque and high temperature.

[0056] The above description is only a preferred specific implementation manner of the present invention, but the protection scope of the present invention is not limited thereto. Any technician familiar with the technical field can make equivalent replacements or changes according to the technical scheme and inventive concept of the present invention within the technical scope disclosed by the present invention, which should be covered by the protection scope of the present invention.
