A discharge port 28 is provided on the lower end surface of the outer shell 2, one end of the discharge port 28 is connected to the external equipment, and the other end of the discharge port 28 is connected to the space at the lower end of the receiving sleeve 4. A guide rail 29 is provided on the support frame 1, and a lifting frame 30 is slidably provided on the guide rail 29. A hydraulic cylinder 31 is fixedly installed on the upper end surface of the support frame 1, and the protruding end of the hydraulic cylinder 31 is connected to the lifting frame 30. A first motor 32 is provided on the lifting frame 30, and the transmission shaft 8 is cooperatively connected to the first motor 32. An impeller 33 is installed on the air inlet block 9, and the impeller 33 is attached to the first motor 32, and the impeller 33 and the transmission shaft 8 are coaxially arranged.

[0023] When grinding the pharmaceutical raw materials, first, the corresponding raw materials are passed into the outer shell 2 through the feed port 27, and then the raw materials will be between the outer shell 2 and the grinding wheel 3. At the same time, the first motor 32 and the second motor 26 are started, and the first motor 32 and the second motor 26 rotate in opposite directions. Since the first motor 32 can drive the rotation of the grinding wheel 3, it will drive the spiral bar 5 to rotate synchronously, and then the raw materials can be preliminarily crushed, and the preliminarily crushed raw materials will flow along the spiral bar 5 between the grinding wheel 3 and the receiving sleeve 4. Since the receiving sleeve 4 and the grinding wheel 3 are in reverse rotation, the crushed raw materials can be fully ground. Since the discharge wheel 25 is connected to the second motor 26, it will rotate with the receiving sleeve 4. When the ground raw materials fall into the upper end of the discharge wheel 25 through the receiving sleeve 4, they will be discharged by the discharge wheel 25 along the discharge port 28, thereby completing the grinding process.

[0024] When the grinding effect needs to be changed, since the grinding effect is determined by changing the distance between the receiving sleeve 4 and the grinding wheel 3, when the distance is close, the ground particles will be smaller. The hydraulic cylinder 31 can drive the lifting frame 30 to move up and down, thereby changing the distance between the grinding wheel 3 and the receiving sleeve 4, thereby changing the grinding effect.

[0025] During grinding, since the impeller 33 rotates with the first motor 32, it will blow air into the air inlet block 9. The wind speed of the incoming air can be changed by multiple variable resistors 21, and then the blown wind is blown into the multiple inclined spray holes 7 along the air inlet hole 10 of the transmission shaft 8. Due to the inclined setting of the multiple inclined spray holes 7, it will blow downward, and then the preliminary crushed raw material slag will be brought into the receiving sleeve 4 for grinding, thereby improving the cleaning effect, and the blown wind will improve the discharge effect, thereby ensuring that the slag can be blown as much as possible between the grinding wheel 3 and the receiving sleeve 4 for grinding during grinding, thereby improving the cleaning effect. The blowing effect can be controlled by changing the position of the variable resistor 21, so that different requirements can be met.

[0026] See also Figures 2 to 10 The control mechanism includes a transmission shaft 8 detachably connected to the grinding wheel 3 and an air inlet block 9 installed at the upper end of the transmission shaft 8. An air inlet hole 10 is provided in the transmission shaft 8, and the air inlet hole 10 is connected to a plurality of oblique spray holes 7. A control sleeve 11 is fixedly installed in the air inlet block 9. The control mechanism also includes an adjustment tube 12 coaxially rotatably connected to the control sleeve 11. A hexagonal groove 13 is provided in the adjustment tube 12, and a rotating disk 14 is installed on the lower end surface of the adjustment tube 12. The rotating disk 14 fits in the control sleeve 11. A plurality of positioning holes 15 are equidistantly provided on the inner wall of the control sleeve 11. A plurality of positioning rods 16 are installed on the upper end surface of the rotating disk 14. The plurality of positioning holes 15 correspond to the positioning rods 16 respectively. A plurality of follower holes 17 are rotatably provided in the control sleeve 11, a plurality of follower rods 19 are equidistantly provided on the bottom plate 18, the follower rods 19 are slidably connected in the follower holes 17, a spring 20 is sleeved on each follower rod 19, the two ends of the plurality of springs 20 are respectively connected to the rotating disk 14 and the bottom plate 18, a plurality of variable resistors 21 are equidistantly rotatably provided on the control sleeve 11, a rotating shaft 22 is rotatably installed on each variable resistor 21, an arc groove 23 with the same number as the variable resistor 21 is opened on the bottom plate 18 along the axis, the rotating shaft 22 is rotatably connected in the arc groove 23, a plurality of intermediate plates 24 are rotatably provided on the bottom plate 18, and the plurality of intermediate plates 24 are respectively rotatably connected to the rotating shaft 22.

[0027] When it is necessary to change the position of the variable resistor 21 to change the air intake speed, first insert the hexagonal wrench into the hexagonal slot 13, and then press the wrench to make the adjusting tube 12 slide downward, thereby releasing the clamping connection between the positioning rod 16 and the positioning hole 15. At this time, turning the wrench can drive the adjusting tube 12 and the rotating disk 14 to rotate accordingly. Since the follower rod 19 is slidably connected in the follower hole 17, the bottom disk 18 will also rotate accordingly. Since the variable resistor 21 is rotationally connected to the control sleeve 11, and the rotating shaft 22 is rotationally connected in the arc groove 23, the middle plate 24 is rotationally connected to the rotating shaft 22 and the bottom disk 18 respectively. When the bottom disk 18 rotates, the variable resistor 21 will only rotate on one side of the rotationally connected to the control sleeve 11, and the rotating shaft 22 will be driven to rotate along the arc groove 23 through the middle plate 24. Since the variable resistor 21 is also rotationally connected to the rotating shaft 22, the middle plate 24 will pull multiple variable resistors 21 to open and close synchronously, please refer to Fig. 9 and Fig.10 The opening and closing states of the fan can be changed by clamping the positioning rod 16 on different positioning holes 15, thereby controlling the wind speed. When the adjustment is completed, the wrench is released, and then the positioning rod 16 is inserted into the positioning hole 15 under the action of the spring 20, thereby ensuring the stability of the adjustment.
