[0030] The working principle of this utility model is as follows: The agitator housing 1 serves to install the planetary gear assembly 2 and the agitator rod assembly 4. The sun gear 201 on the planetary gear assembly 2 is driven to rotate by the motor 7. The sun gear 201 drives the planetary gears 203 to rotate, while the gear ring 202 remains stationary. The planetary gears 203 not only revolve around the planet but also rotate on their own axis. The power of the planetary gear shaft 205 is transmitted to the planetary gear shaft 205 to make the universal joint assembly 402 rotate. The power of the universal joint assembly 402 is transmitted to the next universal joint assembly 402 through the cross 403 and then to the screw rod 401. The transmission angle between the two universal joint assemblies 402 is determined by the crank sleeve 404. The pulley device 3 is responsible for transmitting the power of the motor 7 to the pneumatic clutch 6. The pneumatic clutch 6 is controlled by the magnetic collar 611 to connect or disconnect the next transmission. The pneumatic pipe 607 is connected to the air pressure inside the stirrer shell 1 by the air pipe 105 connected to the air port 103 of the lid. The opening at the top of the pneumatic pipe cover 608 ensures that the negative pressure piston 610 is subjected to atmospheric pressure. When the air pressure inside the pneumatic pipe 607 decreases, the negative pressure piston 610 moves in the opposite direction of the pneumatic pipe cover 608 under the action of the air pressure difference and stretches the tube spring 609. The negative pressure piston 610 is magnetic and attracts the magnetic collar 611 outside the pneumatic pipe 607 to move. The scale on the pneumatic pipe 607 is displayed in the groove of the magnetic collar 611 and indicates the current air pressure inside the stirrer shell 1. When the magnetic collar 611 moves, it causes the shift fork 603 to rotate around the support frame in the middle at a certain angle and shift the collar 605. The collar 605 is always pushed by the clutch spring 604 and tends to engage the active half clutch 601 and the driven half clutch 602. When the collar 605 is shifted by the shift fork 603 and moves away from the driven half clutch 602, it causes the driven half clutch 602 and the active half clutch 601 to disengage, thereby disconnecting the power of the vacuum pump device 5 and stopping its operation. The vacuum pump device 5 extracts the gas inside the stirrer shell 1 to make it close to a vacuum. After receiving power, the crank 507 rotates and drives the connecting rod 508 to make the cylinder piston 505 reciprocate in a linear motion. When the cylinder piston 505 reduces the gas volume inside the tube spring 609, the valve piston 504 moves away from the cylinder piston 505. The retaining ring 511 inside the intake valve 502 sticks to the valve piston 504, causing the valve piston 504 inside the intake valve 502 to block the air inlet, and the intake valve 502 is closed. The retaining ring 511 on the exhaust valve 503 causes the valve piston 504 inside the exhaust valve 503 to move away from the exhaust port, and the exhaust valve 503 is opened to release air. When the cylinder piston 505 reduces the gas volume inside the negative pressure piston 610, the valve piston 504 moves towards the cylinder piston 505. The valve piston 504 moves away from the retaining ring 511 inside the intake valve 502, the intake valve 502 opens, the retaining ring 511 on the exhaust valve 503 sticks to the valve piston 504, the exhaust valve 503 closes, and air intake is achieved. The coupling 8 inserts the drive shaft and driven shaft at both ends into the coupling sleeve 801 and serves to connect the shafts at both ends of the coupling 8.

Any equivalent substitutions or changes made by those skilled in the art within the technical scope disclosed in the present utility model, based on the technical solution and the inventive concept of the present utility model, should be included within the protection scope of the present utility model.

The sleeve (404) is hollow and has a certain turning angle. The sleeve (404) has an opening in the middle. The top of the sleeve (404) is installed on the planetary gear system mounting bracket (104).

8. The double-helix conical mixer for processing 2-imidazolidineones according to claim 1, characterized in that, The vacuum pump device (5) includes a cylinder (501), an inlet valve (502), an outlet valve (503), a valve piston (504), a cylinder piston (505), an open chamber port (506), a crank (507), and a connecting rod (508). The vacuum pump device (5) is located at one end of a coupling (8) located at one end of the pneumatic clutch (6). The shaft at one end of the crank (507) is located inside the coupling (8). The other end is equipped with a connecting rod (508), one end of which is equipped with a cylinder piston (505). One end of the cylinder piston (505) is installed inside a cylinder (501). One end of the cylinder (501) is provided with an inlet valve (502) and an outlet valve (503). The other end of the cylinder (501) is provided with an open chamber air port (506). A valve piston (504) is installed inside the inlet valve (502). The outlet valve... (503) contains a valve piston (504). One end of the intake valve (502) is equipped with a gas pipe flange (106), and the other end of the outlet valve (503) is also equipped with a gas pipe flange (106). A retaining ring (511) with an inner diameter smaller than that of the valve piston (504) is located in the middle of the intake valve (502). One end of the outlet valve (503) is also equipped with a retaining ring (511) with an inner diameter smaller than that of the valve piston (504). The cylinder... The interior of (501) is divided into a closed chamber (509) and an open chamber (510) by the cylinder piston (505). The open chamber (510) is the one closer to the open chamber air port (506) between the closed chamber (509) and the open chamber (510). The retaining ring (511) on the intake valve (502) is set on the valve piston (504), and the retaining ring (511) on the exhaust valve (503) is set outside the valve piston (504).
