The periphery of the first pan-tilt b61 is provided with a notch b7 that cooperates with the tenon b41. 1 , the cover cylinder M4 is provided with a weir, the tenon b41 is placed in the notch b71; and further comprises a baffle b4 for snagging and closing the quantitative channel bl2 at the bottom of the quantitative channel M2, and a third The motor, the third motor power output end is connected to one end of the baffle b4, the other end of the baffle b4 is provided with a first magnet, and the bottom of the preparation body bl is provided with a second magnet that cooperates with the first magnet; the second motor b52 a pressure sensor bl5 is disposed between the second cloud platform b62; a circuit box bl l is disposed on the top cover b2, and a control circuit is disposed in the circuit box M1, the control circuit includes a CPU, and the first motor B51. The second motor b52, the third motor, and the pressure sensor M5 are all connected to the CPU signal. Specifically, the salty salt storage chamber b3 stores salty salt, the fixed column M3 end with the prepared thread is arranged at the mouth of the quantitative channel M2, the mouth of the threaded closed quantitative channel M2 is prepared, and the second motor b52 drives the fixed column M3 rotates, and the thread rotation rotates to move the salt salt to the quantitative channel M2. When the salty salt in the metering channel M2 is full, the pressure is increased when the thread is rotated and then placed. The pressure sensor bl5 between the second motor b52 and the second pan/tilt b62 senses a pressure signal, and judges that the salty salt has been filled with the quantitative channel bl2.
