Description

Technical Field

[0001] This utility model relates to the field of grinding machines, and in particular to a grinding machine with a dust-isolating function. Background Technology

[0002] A grinding mill is a device used to grind materials. It uses mechanical force to grind lumpy or granular materials into powder or finer particles.

[0003] During the grinding process, some materials may generate dust. If this dust is not controlled, it may harm the health of the operators. Furthermore, external dust entering the grinding machine and mixing with the materials will affect the purity and safety of the product.

[0004] Therefore, if the dust generated during the grinding process is not controlled, it will endanger the health of the operators. Furthermore, if external dust enters the grinding machine and mixes with the materials, it will affect the purity and safety of the product. To address this issue, a grinding machine with dust isolation function can be designed. This function can prevent dust from rising in the grinding area through a check valve and suppress dust from flowing out of the feed funnel from inside the upper shell through a spiral groove, thus solving the above problems. Utility Model Content

[0005] In order to overcome the problem that if the dust generated by the material is not controlled during the use of the grinding machine, it will cause harm to the health of the operators, and the external dust will affect the purity and safety of the product after it enters the grinding machine and mixes with the material.

[0006] The technical solution of this utility model is as follows: a grinding machine with dust isolation function, including an upper shell; and a spiral groove. A feeding funnel is provided at the upper end of the upper shell. A cover is rotatably connected to the rear of the upper end of the feeding funnel. A spiral groove is provided at the bottom end of the feeding funnel. A crushing hopper is provided at the lower end of the spiral groove. A dividing plate is provided at the lower end of the crushing hopper. Four converging grooves are provided on the upper surface of the dividing plate. Four check valves are installed at the lower end of the dividing plate. An inclined surface is provided at the bottom of the inside of the crushing hopper. Multiple lower leakage holes are provided on the inclined surface. Multiple upper leakage holes are provided on the side wall of the crushing hopper. A blade is provided at the upper end of the inclined surface.

[0007] Preferably, after opening the cover, the material is poured into the feed hopper. The material spirals down through the spiral groove into the crushing hopper. The spiral groove can prevent dust inside the upper shell from flowing out of the feed hopper. Then, the motor is started to make the driven shaft and blades rotate rapidly through the drive shaft, drive bevel gear and driven bevel gear. The material crushed by the blades leaks out from the lower and upper leakage holes and falls into the collection tank. Then it passes through the check valve and enters the material grinding area. The initial crushing treatment by the blades can shorten the time required for subsequent grinding. The inclined surface makes it easier for the crushed material to fall from the outer edge of the crushing hopper. The check valve can prevent dust from rising in the grinding area to further prevent dust from contacting the staff. After the material is added, the cover is closed to prevent external dust from entering the equipment.

[0008] Preferably, the upper end face of the crushing bucket is fixedly connected to the upper shell, the lower end of the collecting groove is connected to the check valve, and the blade is rotatably connected to the crushing bucket.

[0009] Preferably, the lower end of the blade is fixedly connected to a driven shaft, which passes through the crushing hopper and the separator disc, and a driven bevel gear is fixedly connected to the driven shaft.

[0010] Preferably, a driving bevel gear meshes with one side of the lower end of the driven bevel gear, and a drive shaft is fixedly connected to one side of the driving bevel gear.

[0011] Preferably, a motor is mounted on one side of the drive shaft and on one side of the upper housing, and a reducer is mounted on the lower end of the driven shaft and on the lower end face of the partition plate.

[0012] Preferably, a grinding pestle is mounted on the lower end of the reducer via a connecting shaft, and a lower housing is provided on the outer side of the grinding pestle.

[0013] Preferably, the lower end face of the upper shell is fixedly connected to the partition plate, the lower end face of the partition plate is fixedly connected to the lower shell, and a discharge valve is installed at the lower end of the lower shell.

[0014] The beneficial effects of this utility model are:

[0015] By incorporating a spiral groove and a check valve, material is poured into the feed hopper after the cover is opened. The material spirals down through the groove into the crushing hopper. The spiral groove prevents dust inside the upper casing from overflowing from the feed hopper. The motor is then started to rapidly rotate the driven shaft and blades. The material crushed by the blades leaks through the lower and upper drain holes and falls into the collection tank. It then passes through the check valve into the grinding area. The initial crushing by the blades shortens the time required for subsequent grinding, while the check valve prevents dust from rising from the grinding area, further preventing dust from contacting the workers. After feeding is complete, the cover is closed to prevent external dust from entering the equipment, thus preventing dust from harming the health of the operators and preventing external dust from entering the grinder and mixing with the material being ground. This also shortens the processing time. Attached Figure Description

[0021] The present invention will be further described below with reference to the accompanying drawings and embodiments.

[0022] Please see Figures 1-4This utility model provides an embodiment of a grinding machine with dust isolation function, including an upper shell 1; and a spiral groove 4. A feeding funnel 2 is provided at the upper end of the upper shell 1, and a cover 3 is rotatably connected to the rear of the upper end of the feeding funnel 2. A spiral groove 4 is provided at the bottom end of the feeding funnel 2, and a crushing hopper 5 is provided at the lower end of the spiral groove 4. A dividing plate 6 is provided at the lower end of the crushing hopper 5, and four collecting grooves 7 are provided on the upper surface of the dividing plate 6. Four check valves 8 are installed at the lower end of the dividing plate 6. An inclined surface 9 is provided at the bottom inside the crushing hopper 5, and multiple lower drain holes 10 are provided on the inclined surface 9. Multiple upper drain holes 11 are provided on the side wall of the crushing hopper 5. A blade 12 is provided at the upper end of the inclined surface 9. After opening the cover 3, the material is poured into the feeding funnel 2, and the material passes through the spiral groove 4. The material descends spirally into the crushing hopper 5. The spiral groove 4 can prevent dust inside the upper housing 1 from flowing out of the feed funnel 2. Then, the motor 17 is started to make the driven shaft 13 and the blade 12 rotate rapidly through the drive shaft 16, drive bevel gear 15 and driven bevel gear 14. The material crushed by the blade 12 leaks out from the lower leakage hole 10 and the upper leakage hole 11 and falls into the collection tank 7. Then it passes through the check valve 8 and enters the material grinding area. The initial crushing treatment of the blade 12 can shorten the time required for subsequent grinding. The inclined surface 9 makes it easier for the crushed material to fall from the outer edge of the crushing hopper 5. The check valve 8 can prevent dust from rising in the grinding area to further prevent dust from contacting the staff. After the feeding is completed, the cover 3 is closed to prevent external dust from entering the equipment.

[0023] Please see Figure 2 , Figure 3 and Figure 4 In this embodiment, the upper end face of the crushing hopper 5 is fixedly connected to the upper housing 1, the lower end of the collecting groove 7 is connected to the check valve 8, the blade 12 is rotatably connected to the crushing hopper 5, the lower end of the blade 12 is fixedly connected to the driven shaft 13, and the driven shaft 13 passes through the crushing hopper 5 and the separator 6. The driven bevel gear 14 is fixedly connected to the driven shaft 13, and a drive bevel gear 15 meshes with one side of the lower end of the driven bevel gear 14. A drive shaft 16 is fixedly connected to one side of the drive bevel gear 15. The motor 17 causes the driven shaft 13 and the blade 12 to rotate rapidly through the drive shaft 16, the drive bevel gear 15 and the driven bevel gear 14 to crush the material falling into the crushing hopper 5.

[0024] Please see Figure 2 and Figure 4In this embodiment, a motor 17 is installed on one side of the drive shaft 16, and the motor 17 is installed on one side of the upper housing 1. A reducer 18 is installed at the lower end of the driven shaft 13, and the reducer 18 is installed on the lower end face of the partition plate 6. A grinding pestle 19 is installed at the lower end of the reducer 18 through a connecting shaft. A lower housing 20 is provided on the outside of the grinding pestle 19. After the driven shaft 13 transmits power to the reducer 18, the reducer 18 rotates at a slower speed than the driven shaft 13 through the connecting shaft connecting the reducer 18 and the grinding pestle 19, so as to grind the material that falls into the lower housing 20 through the grinding pestle 19. The lower end face of the upper housing 1 is fixedly connected to the partition plate 6, and the lower end face of the partition plate 6 is fixedly connected to the lower housing 20. A discharge valve 21 is installed at the lower end of the lower housing 20. After opening the discharge valve 21, the ground material in the lower housing 20 can be discharged.

[0025] When in use, after opening the cover 3, pour the material into the feed hopper 2. The material spirals down through the spiral groove 4 into the crushing hopper 5. The spiral groove 4 can prevent dust inside the upper shell 1 from flowing out of the feed hopper 2. Then, start the motor 17 to make the driven shaft 13 and the blade 12 rotate quickly through the drive shaft 16, drive bevel gear 15 and driven bevel gear 14. The material crushed by the blade 12 leaks out from the lower hole 10 and the upper hole 11 and falls into the collection groove 7. Then, it passes through the check valve 8 and enters the grinding area of ​​the material. The initial crushing treatment of the blade 12 can shorten the time required for subsequent grinding. The inclined surface 9 makes it easier for the crushed material to fall from the outer edge of the crushing hopper 5. The check valve 8 can prevent dust from rising in the grinding area to further prevent dust from contacting the staff. After the material is added, close the cover 3 to prevent external dust from entering the equipment.

[0026] At the same time, the driven shaft 13 transmits power to the reducer 18 at the lower end. The reducer 18, through the connecting shaft connecting the reducer 18 and the grinding pestle 19, allows the grinding pestle 19 to rotate at a slower speed than the driven shaft 13, so as to grind the material that has fallen into the lower housing 20. After grinding is completed, the material that has been ground can be discharged from the lower housing 20 by opening the discharge valve 21.

[0027] Through the above steps, by setting the spiral groove 4 and the check valve 8, after opening the cover 3, the material is poured into the feed hopper 2. The material spirals down through the spiral groove 4 into the crushing hopper 5. The spiral groove 4 can prevent dust inside the upper shell 1 from flowing out of the feed hopper 2. Then, the motor 17 is started to make the driven shaft 13 and the blade 12 rotate rapidly. The material crushed by the blade 12 leaks out from the lower leakage hole 10 and the upper leakage hole 11 and falls into the collection groove 7. Then, it passes through the check valve 8 and enters the grinding area of ​​the material. The initial crushing treatment of the blade 12 can shorten the time required for subsequent grinding, while the check valve 8 can prevent dust from rising in the grinding area to further prevent dust from contacting the workers. After the material is added, the cover 3 is closed to prevent external dust from entering the equipment, thereby preventing dust from harming the health of the operators and preventing external dust from entering the grinder and mixing with the material being ground. It also shortens the processing time.
