Referring to fig. 1-2, in step S3, the pulverizer includes a housing 1, a motor 3, a rotary shaft 12, an upper grinding disc 5, a lower grinding disc 6, a side grinding disc 8, and an anti-blocking device. A feeding hole 13 and a discharging hole 10 are formed in the machine body 1, the feeding hole 13 is located at the top of the machine body 1, and the discharging hole 10 is located at the bottom of the machine body 1. The inside cavity of organism 1 just is cylindricly, and 1 bottom of organism is fixed with landing leg 2, and landing leg 2 is provided with four, and four landing legs 2 equipartitions are around the bottom of organism 1. A second vibrator 4 is arranged on the shell of the machine body 1, and the second vibrator 4 is a bin wall vibrator and is arranged on the shell at the bottom of the machine body 1.
In above-mentioned technical scheme, the setting of landing leg 2 for organism 1 stably supports on basic ground, and the setting of second vibrator 4 is mainly in order to prevent that discharge gate 10 and organism 1 are inside to be blockked up for the unloading speed.
Referring to fig. 1-2, the upper grinding disc 5, the lower grinding disc 6 and the side grinding disc 8 are all located inside the machine body 1, the upper grinding disc 5 is located below the lower grinding disc 6, the side grinding disc 8 is located around the lower grinding disc 6, and the upper grinding disc 5 and the side grinding disc 8 are all fixed on the inner wall of the machine body 1. The upper surface and the lower surface of the upper grinding disc 5 are both inclined planes, and the upper surface and the lower surface of the upper grinding disc 5 are both gradually inclined upwards from the middle part to the periphery. Similarly, the upper surface of the lower grinding disc 6 is also designed to be inclined and is also inclined upwards gradually from the middle to the periphery, except that the inclination angle of the upper surface of the lower grinding disc 6 is gentle relative to the lower surface of the upper grinding disc 5, so that the gap between the upper grinding disc 5 and the lower grinding disc 6 is gradually widened from the center to the periphery.
Referring to fig. 1-2, the motor 3 is fixed at the bottom center of the machine body 1, the lower end of the rotating shaft 12 is fixed on the output shaft of the motor 3, and the upper end passes through the center of the lower grinding disc 6 and is inserted at the bottom of the upper grinding disc 5. The lower grinding disc 6 is fixed on the rotating shaft 12 and is coaxially and rotatably arranged with the rotating shaft 12, and the upper end of the rotating shaft 12 rotates in the upper grinding disc 5. The surface all around of the upper millstone 5 is fixed on the inner wall of the machine body 1, a first powder gap 15 is arranged between the upper millstone 5 and the lower millstone 6, and a second powder gap 11 is arranged between the side millstone 8 and the lower millstone 6. The upper grinding disc 5 is provided with a blanking hole 7, the blanking hole 7 is communicated with a first powder gap 15, and the first powder gap 15 is communicated with a second powder gap 11. The side grinding disc 8 is enclosed around the lower grinding disc 6, and the gap between the side grinding disc 8 and the lower grinding disc 6 is gradually narrowed from top to bottom. The narrowest gap between the upper millstone 5 and the lower millstone 6 is wider than the narrowest gap between the side millstones 8 and the lower millstone 6, so that the green south tea is ground more fully in the second powder gap 11. The diameter of the lower grinding disc 6 is gradually reduced from top to bottom, so that the second powder gap 11 is gradually close to the center of the lower grinding disc 6 from top to bottom. The peripheral surface of the lower grinding disc 6 is provided with a first grinding tooth 14, the side grinding disc 8 is provided with a second grinding tooth 16, and the first grinding tooth 14 and the second grinding tooth 16 are both positioned in the second powder gap 11.
In the technical scheme, in order to improve the grinding fineness of the southernwood, a first powder gap 15 for primary grinding is arranged between the upper grinding disc 5 and the lower grinding disc 6, and a second powder gap 11 for secondary grinding is arranged between the side grinding disc 8 and the lower grinding disc 6. After the motor 3 starts, the axis of rotation 12 will drive lower millstone 6 and rotate, after treating the broken powder of the blue or green south tea of crocus to enter into organism 1 through feed inlet 13, can enter into first powder clearance 15 through unloading hole 7 earlier, because side mill 8 and lower mill 6 are fixed on organism 1, and lower mill 6 is rotating, consequently enter into the broken powder of the blue or green south tea in first powder clearance 15 will be crushed between lower mill 6 and upper mill 5, levigate, and move outwards gradually, thereby enter into and carry out the secondary grinding in the second powder clearance 11. In order to ensure the grinding effect, the radial grooves should be formed on both the lower surface of the lower grinding disc 6 and the upper surface of the upper grinding disc 5, and preferably, the radial grooves on the lower grinding disc 6 are vertically meshed with the radial grooves on the upper grinding disc 5. The upper surface of the lower grinding disc 6 is designed in an inclined mode, so that the green south tea powder can enter the blanking holes 7 quickly, and in order to enable the green south tea powder to enter the second powder gap 11 after being fully ground in the first powder gap 15 for the first time, the gap between the upper grinding disc 5 and the lower grinding disc 6 is gradually widened from the center to the periphery. The green south tea, after being ground in the second powder gap 11, falls to the bottom in the machine body 1 and is discharged from the discharge hole 10.
Referring to fig. 1-2, the anti-blocking device is used to pass through the blanking hole 7 so as to keep the blanking hole 7 unobstructed. The anti-blocking device comprises a cylinder 91, a fixing plate 92 and a contact pin 93. Cylinder 91 is fixed at organism 1 top center, and fixed plate 92 and contact pin 93 all are located organism 1, and fixed plate 92 is located the top of runner stone 5 and fixes on cylinder 91. Contact pin 93 is fixed in fixed plate 92 bottom and is used for wearing down blanking hole 7, and blanking hole 7 and contact pin 93 all are provided with a plurality ofly, a plurality of blanking holes 7 and a plurality of contact pin 93 position one-to-one. The cylinder 91 is used for driving the fixing plate 92 and the inserting pin 93 to move up and down so that the inserting pin 93 can be smoothly inserted into the blanking hole 7. The diameters of the inserting pin 93 and the blanking hole 7 are gradually reduced from top to bottom, and the diameter of the inserting pin 93 is smaller than that of the blanking hole 7. A first vibrator 94 is fixed to the bottom of the fixed plate 92 to vibrate the pin 93 in the blanking hole 7. When the pin 93 is inserted into the blanking hole 7, the first vibrator 94 starts to operate.
In the technical scheme, in order to enable the green and south tea to rapidly enter the blanking hole 7, the diameter of the blanking hole 7 is gradually reduced from top to bottom, so that the blanking hole 7 has a certain taper, and rapid blanking is facilitated. In addition, in order to enable the inserting pin 93 to be smoothly and quickly inserted into the blanking hole 7, the inserting pin 93 is also provided with a certain taper, so that the inserting resistance is reduced, the inserting pin 93 is prevented from being broken, and the service life of the inserting pin 93 is prolonged. The milling machine has long service life, the phenomenon that the blanking hole 7 is not smooth or blocked and cannot discharge materials can occur, and in order to overcome the problem, the invention specially designs an anti-blocking device. When the blanking is not smooth in the blanking hole 7, the air cylinder 91 can be started to enable the fixing plate 92 and the inserting pin 93 to move downwards, and after the inserting pin 93 is inserted into the blanking hole 7, the first vibrator 94 can be started to enable the inserting pin 93 to vibrate in the blanking hole 7, so that the green south tea dust adhered to the inner wall of the blanking hole 7 can shake off, and a good anti-blocking effect can be achieved.
