The output port of the powder pumping machine 24 is fixedly sleeved with a corrugated telescopic tube 26. A long groove 29 is provided on the inner wall of the box body 1. Through the belt 2 11 and the belt 1 7 devices, the drying and grinding equipment only needs to be equipped with two power devices to realize operation, realizing the functions of stirring and drying, grinding and screening, thereby improving the energy utilization and practicality of the drying and grinding equipment.

[0030] Among them, the output port of the hot air device 4 is fixedly sleeved with a hot air pipe, and the end of the hot air pipe passes through the top of the box body 1 and reaches the inside of the box body 1. The top of the box body 1 is fixedly equipped with a support frame 1, and the box body 1 is fixedly connected to the stirring motor 5 through the support frame 1. There are three transmission wheels 6, one transmission wheel 16 is fixedly sleeved with the output shaft of the stirring motor 5, and the other two transmission wheels 16 are driven by the transmission wheel 16 fixedly sleeved with the output shaft of the stirring motor 5 through a belt 17. The bottoms of the three transmission wheels 6 are all rotatably connected to the top of the box body 1. The hot air pipe can guide the hot air generated by the hot air device 4, so that the hot air can fully contact the ground raw materials with the hot air, thereby improving the drying effect of the equipment, and the three transmission wheels 16 can all drive the rotating rod 23 to rotate, so that the raw materials are extracted by the powder extractor 24 and discharged and accumulated by the corrugated telescopic pipe 26, and are spread evenly in the hot air drying area on the inner wall of the box body 1, thereby increasing the contact area between the hot air and the ground raw materials, and further improving the drying effect of the equipment on the powder.

[0031] Among them, the left outer wall of the box body 1 is fixedly equipped with a support frame 2, the outer edge of the transmission wheel 29 is provided with a boss, the outer edge of the gear 10 is provided with a tooth groove, and the inner wall of the tooth groove is engaged with the outer edge of the boss, the transmission rod 13 is located at one end of the inner wall of the sleeve 15 and is fixedly sleeved with a limiting ring, and the slider 17 is located at one end of the inner wall of the slide groove 16 and is fixedly assembled with the outer wall of the limiting ring, and both ends of the positioning rod 19 are fixedly assembled with the slider 17. The transmission wheel 29 can engage with the gear 10 during the rotation process, so that the two grinding rods 28 engage to grind the raw materials. At the same time, the gear 2 12 is used to push the transmission rod 13 to move briefly and at a high frequency, so that the screening net 21 vibrates, thereby improving the screening effect of the screening net 21 on the powdered raw materials.

[0032] Among them, the front and back of the box body 1 are respectively provided with a material trough and a strip groove, and the sealing door 2 and the material taking plate 20 are respectively connected to the inner walls of the material trough and the strip groove through the existing pin technology. There are two grinding rods 28, and the two grinding rods 28 are engaged with each other. The sealing door 2 can facilitate the user to take out the dried powdered raw materials, and the user can remove the material taking plate 20 to clean the larger volume of raw materials remaining on the screen net 21, thereby improving the user's maintenance efficiency of the drying and grinding equipment.

[0033] Among them, a through groove is opened on the inner wall of the box body 1, and the outer wall of the fixed bar 27 is slidably connected to the inner wall of the through groove, the inner wall of the long groove 29 is slidably connected to the outer wall of the screen net 21, and the outer wall of the screen net 21 is slidably connected to the inner wall of the box body 1. The through groove can ensure that the fixed bar 27 has sufficient space for movement when the transmission rod 13 moves, and ensure that the transmission rod 13 can push the transmission plate 22 to drive the screen net 21 to move, thereby achieving the effect of high-frequency vibration to screen the powdered raw materials.

[0034] Among them, the end of the fixing bar 27 away from the pull rod 25 is fixedly assembled with the outer wall of the slider 17, and the sleeve 15 is fixedly connected to the fixing bar 27 through the slider 17. The end of the transmission rod 13 away from the fixed plate 14 is provided with an inclined surface, and the gear 2 12 is connected to the transmission wheel 2 9 through the belt 2 11. The slider 17 can transmit the force when the limit ring slides to the pull rod 25, so that the transmission plate 22 can be translated, so that the transmission plate 22 can vibrate at a high frequency. When the transmission wheel 2 9 rotates, the gear 2 12 synchronously drives the transmission rod 13 overlapped with the gear 2 12 to be translated, thereby ensuring that the transmission plate 22 can move steadily, thereby improving the stability of the transmission plate 22 and the screening net 21 during the movement.

[0035] Among them, the length of the slide groove 16 is equal to the distance from the through groove and the screen mesh 21 to the inner wall of the end of the long groove 29. The transmission rod 13 is made of chrome-plated metal. Metal chromium has the characteristics of hardness, which can reduce the wear of the transmission rod 13 when the gear 2 12 rotates, thereby extending the service life of the transmission rod 13.

[0036] Among them, the inner wall of the box body 1 is also fixedly equipped with a partition 2, and the interior of the box body 1 is divided into a crushing and screening area, a conveying area and a hot air drying area by the screening net 21 and the partition 2.

[0037] Among them, the outer edge of the rotating rod 23 is fixedly equipped with stirring blades. There are several stirring blades, and the several stirring blades are evenly distributed along the outer edge of the rotating rod 23. The stirring blades can stir the accumulated powder raw materials, thereby increasing the contact area between the accumulated raw materials and the hot air, thereby improving the drying effect of the equipment on the powder raw materials.

[0038] Among them, the end of the corrugated telescopic tube 26 passes through the partition 2 to the hot air drying area, and the outer walls of the sealed door 2 and the material-removing plate 20 are fixedly equipped with handles. The handles can facilitate the user to open or close the equipment to extract raw materials and clean up residues, thereby improving the user's work efficiency.

[0039] Working principle: first, after the drying and grinding equipment is assembled, the equipment is powered on, and then the user can put the raw materials into the equipment through the pouring chute 3. At this time, the transmission wheel 2 9 is driven by the grinding motor 8 to mesh with the gear 1 10, so that the two grinding rods 28 start to grind the raw materials. The ground raw materials will fall on the screen net 21 under the blocking effect of the transmission plate 22 and the action of gravity. At the same time, the transmission wheel 2 9 will drive the gear 2 12 to rotate synchronously through the belt 2 11 during the rotation process, and the rotation of the gear 2 12 and the gear 1 10 will make the inclined surface on the transmission rod 13 receive thrust, causing the transmission rod 13 to move horizontally. At this time, the limit ring will drive the slider 17 to move, and under the positioning effect of the positioning rod 19 and the action of the two sets of transmission rods 13, the pull rod 25 will steadily drive the screen net 21 to move. When the transmission rod 13 coincides with the tooth grooves on the gear 2 12 and the gear 1 10, the transmission rod 13 is The thrust disappears, and the return spring 18 pushes the transmission rod 13 to reset, so that the screening net 21 vibrates at a high frequency as long as the grinding motor 8 is in operation, so that the ground raw materials are fully screened, and the fine powdered raw materials after grinding fall into the bottom inner wall of the box body 1, and then the powder extractor 24 extracts the powdered raw materials and transports them to the hot air drying area through the corrugated telescopic tube 26, and the hot air generated by the hot air device 4 is transported to the hot air drying area through the hot air pipe. The user can drive the transmission wheel 6 to rotate by the stirring motor 5, and use the rotating rod 23 to stir the powdered raw materials to increase the contact area between the hot air and the powdered raw materials. After the drying operation is completed, the user can turn off the power of the equipment, remove the sealing door 2 and the material taking plate 20, and collect the dried powdered raw materials in the hot air drying area and clean the raw materials with a larger volume remaining on the screening net 21, or reuse the equipment for grinding and drying operations until the operation is completed.
