An auxiliary gear is fixedly connected to the upper outer surface of the main hybrid rod, and a rack is fixedly connected to the outer surface of the top frame. The outer surface of the rack meshes with the outer surface of the auxiliary gear.

[0006] As a preferred embodiment of the above technical solution, the limiting component includes a mounting bracket fixedly connected to the bottom of the protective cover. A guide rod is fixedly connected to the outer surface of the mounting bracket. A limiting push plate is slidably connected to the outer surface of the guide rod. A second shock absorber is fixedly connected to one end of the limiting push plate away from the mounting bracket. A shaped rod is fixedly connected to the other end of the second shock absorber.

[0009] The beneficial effects of this utility model are as follows: Through the meshing transmission of bevel gear and bevel ring and the threaded transmission of lateral threaded rod and sliding frame, when the top frame rotates, it drives the sliding frame to slide radially on the top frame, improving the mixing effect of crude benzophenone and organic solution, thereby improving the overall practicality and functionality.

A motor 2 is fixedly connected to the bottom end of the protective housing 1. A main shaft 3 is fixedly connected to the output end of the motor 2 through the protective housing 1. A scraper 4 is fixedly connected to the outer surface of the main shaft 3. A scraper 5 is fixedly connected to the inner surface of the scraper 4. The outer surface of the scraper 5 abuts against the inner surface of the protective housing 1. A top frame 6 is fixedly connected to the upper end of the main shaft 3. A mixing component 7 is slidably connected to the inner surface of the top frame 6. A limiting component 8 abuts against the inner surface of the middle part of the top frame 6. A beveled ring 9 is fixedly connected to the inner surface of the protective housing 1. A protective cover 10 is snapped onto the upper end of the protective housing 1. The limiting component 8 includes components that are fixed to the bottom of the protective cover 10. A mounting bracket 801 is fixedly connected to the outer surface of the mounting bracket 801. A guide rod 802 is fixedly connected to the outer surface of the mounting bracket 801. The guide rod 802 guides the limiting push plate 803 and the irregular rod 805. The limiting push plate 803 is slidably connected to the outer surface of the guide rod 802. A second shock absorber 804 is fixedly connected to one end of the limiting push plate 803 away from the mounting bracket 801. The irregular rod 805 is fixedly connected to the other end of the second shock absorber 804. A limiting roller 806 is rotatably connected to the outer surface of the irregular rod 805. The outer surface of the limiting roller 806 abuts against the inner surface of the top frame 6. A third shock absorber 8 is fixedly connected between the opposite surfaces of adjacent irregular rods 805. 07. A slanted chuck 808 is slidably connected to the inner surface of the mounting bracket 801. A slanted guide bar is fixedly connected to one end of the slanted chuck 808 near the irregular rod 805. A slanted guide plate is fixedly connected to one end of the limiting push plate 803 away from the irregular rod 805. The outer surface of the slanted guide bar is slidably connected to the inner surface of the slanted guide plate. An adjusting threaded rod 809 is threadedly connected to the inner surface of the slanted chuck 808. A knob 810 is fixedly connected to the upper end of the adjusting threaded rod 809. Through the linkage between the irregular rod 805 and the third shock absorber 807, it can be ensured that each limiting roller 806 moves synchronously and forms a stable triangular structure, uniformly transmitting the radial vibration of the rotating production. The material is then transferred to each of the second shock absorbers 804, improving the overall stability and reliability. It also facilitates adjustment of the coaxiality of the protective housing 1, main shaft 3, and protective cover 10 during installation. By adjusting the threaded drive of the threaded rod 809 and the inclined chuck 808, and the interaction between the inclined guide block on the inclined chuck 808 and the inclined guide plate on the limit push plate 803, turning the knob 810 can drive each limit push plate 803 to move synchronously, thereby changing the distance between the limit push plate 803 and the irregular rod 805, thus changing the stress on the second shock absorber 804. This facilitates user adjustment and overall installation, improving overall convenience and practicality.

[0014] like Figures 1 to 8As shown, a hybrid main rod 702 is rotatably connected to the inner surface of the sliding frame 701, and several hybrid auxiliary rods 703 are fixedly connected to the outer surface of the hybrid main rod 702. A lateral threaded rod 704 is rotatably connected to the inner surface of the top frame 6. The inner surface of the sliding frame 701 and the outer surface of the lateral threaded rod 704 are threadedly driven. A bevel gear 705 is fixedly connected to one end of the lateral threaded rod 704 away from the main shaft 3. The outer surface of the bevel gear 705 meshes with the outer surface of the bevel gear ring 9. The bottom end of the sliding frame 701 is fixedly connected to...

The outer surface of the contact plate 707 is slidably connected to the inner surface of the sliding frame 701. A pressure sensor is installed on the contact plate 707, and the pressure sensor is electrically connected to the motor 2. When the pressure sensor is activated, the motor 2 is started to reverse, thereby ensuring that the sliding frame 701 reciprocates while preventing component collisions, improving overall stability and safety. The upper outer surface of the hybrid main rod 702... An auxiliary gear 708 is fixedly connected to the outer surface of the top frame 6. A rack 709 is fixedly connected to the outer surface of the rack 709 and the outer surface of the auxiliary gear 708. A feed inlet 11 is provided on the left outer surface of the protective shell 1. A base frame 12 is fixedly connected to the bottom end of the protective shell 1. A water pump 13 is fixedly connected to the upper end of the inner part of the base frame 12. The output end of the water pump 13 is connected to the bottom end of the protective shell 1. The transmission is achieved through the meshing of the bevel gear 705 and the bevel ring 9, and the connection between the lateral threaded rod 704 and the sliding frame 70. The threaded drive of 1, when the top frame 6 rotates, drives the sliding frame 701 to slide radially on the top frame 6, improving the mixing effect of crude benzophenone and organic solution, thereby improving the overall practicality and functionality. Through the meshing transmission of auxiliary gear 708 and rack 709, when the auxiliary gear 708 moves radially, it drives the mixing main rod 702 and mixing secondary rod 703 to rotate, thereby forming a vortex, avoiding uneven mixing that leads to local crystallization, and further improving the overall practicality and reliability.

[0015] Working principle: Crude benzophenone solvent and auxiliary organic solvent are fed into the protective shell 1 through multiple feed ports 11. The motor 2 is started, and the output end of the motor 2 drives the main shaft 3 and scraper 4 to rotate. Through the meshing transmission of bevel gear 705 and bevel ring 9, the threaded transmission of lateral threaded rod 704 and sliding frame 701, and the meshing transmission of auxiliary gear 708 and rack 709, the mixing main rod 702 and mixing secondary rod 703 can be driven to perform a compound motion of circumferential rotation, radial reciprocating motion and self-rotation, which improves the internal mixing effect. After completion, the water pump 13 is started to discharge the mixed solvent inside the protective shell 1, improving the overall finished product effect.
