[0023] A discharge structure of a high-viscosity sand mill comprises a grinding machine body 1, a grinding cylinder 2 is fixedly connected to one side of the grinding machine body 1, a feed port 3 is fixedly connected to the top of the circumference of the grinding cylinder 2, a discharge port 4 is fixedly connected to the bottom of the circumference of the grinding cylinder 2, a storage tank 5 is provided in the inner cavity of the grinding machine body 1, a collecting tank 7 is fixedly connected to the bottom of one side of the grinding machine body 1, a guide plate 6 is fixedly connected to one side of the grinding machine body 1, the guide plate 6 is inclined to the horizontal plane, a motor 9 is fixedly connected to the top of the grinding machine body 1, and the output of the motor 9 The shaft is fixedly connected with a screw rod 10, the other end of the screw rod 10 passes through the support plate 8 and extends to the outside of the support plate 8, the outer surface of the screw rod 10 is movably connected with a sliding plate 11, the bottom of the sliding plate 11 is fixedly connected with a connecting rod 12, one side of the connecting rod 12 is fixedly connected with a scraper 14, the inner cavity of the connecting rod 12 is provided with a groove 13, the inner cavity of the scraper 14 is slidably connected with a fixed plate 15, one end of the fixed plate 15 is fixedly connected with a locking spring 16, and the other end of the locking spring 16 is fixedly connected to the top of the inner cavity of the scraper 14.
[0024] By adopting the above technical solution, the operator puts the material into the inner cavity of the grinding cylinder 2 through the feed port 3. After the grinding cylinder 2 finishes grinding the material, it is discharged into the storage tank 5 through the discharge port 4. Then the operator turns on the motor 9, so that the motor 9 drives the screw rod 10 of the output shaft to rotate. The sliding plate 11 slides on the outer surface of the screw rod 10 as the screw rod 10 rotates. The sliding plate 11 drives the connecting rod 12 to move synchronously. The connecting rod 12 drives the scraper 14 to slide in the inner cavity of the storage tank 5, pushing the ground material placed in the storage tank 5 to The scraper 14 is moved to the top of the guide plate 6 and slides along the top of the guide plate 6 to the top of the collecting trough 7, and then enters the collecting box for collection. The utility model can prevent the material from accumulating in the storage trough 5, and avoid the material from being unable to flow out of the storage trough 5 completely, thereby improving the utilization rate of the material. The operator can pull the fixing plate 15 so that the fixing plate 15 compresses the locking spring 16 and disengages from the inner cavity of the groove 13. The operator can remove the scraper 14 from the connecting rod 12, and perform maintenance and installation on the scraper 14, thereby improving the service life of the scraper 14.
[0025] Specifically, Figure 3 , Figure 4 As shown, the inner cavity of the collecting tank 7 is slidably connected with a top plate 22, the bottom of the top plate 22 is fixedly connected with a reset spring 23, the bottom of the reset spring 23 is fixedly connected to the bottom of the inner cavity of the collecting tank 7, the inner cavity of the collecting tank 7 is slidably connected with a connecting plate 27, the top two sides of the connecting plate 27 are respectively fixedly connected with conductive rods 25, the bottom of one side of the conductive rod 25 is fixedly connected with a stop spring 26, and the bottom of the stop spring 26 is fixedly connected to the top of the connecting plate 27.
[0026] By adopting the above technical solution, the operator places the collection box on the top of the collection trough 7, and turns on the motor 9 to drive the scraper 14 to move, so that the scraper 14 pushes the material in the storage trough 5 into the collection box. Under the action of gravity, the collection box pushes the top plate 22 to move downward, and the top plate 22 gradually compresses the return spring 23 until the bottom protrusion of the top plate 22 contacts the conductive rod 25 on one side. The top plate 22 drives the conductive rod 25 to move downward and gradually compresses the stop spring 26. The two conductive rods 25 are no longer in contact, so that the power supply is cut off, the motor 9 no longer rotates, and the scraper 14 no longer pushes the material into the collection box. The utility model can accurately control the weight of the collected material, prevent material overflow, and keep the working area clean.
[0027] Specifically, Figure 3 , Figure 4As shown, cross plates 28 are slidably connected to both sides of the inner cavity of the connecting plate 27, and connecting springs 29 are fixedly connected to the opposite back surfaces of the two cross plates 28. The other end of the connecting spring 29 is fixedly connected to the inner cavity of the connecting plate 27. A main slide groove 30 is opened in the inner cavity of the collecting groove 7, and auxiliary slide grooves 24 are opened on both sides of the main slide groove 30. The cross plates 28 are slidably connected to the inner cavities of the main slide groove 30 and the auxiliary slide groove 24.
[0028] By adopting the above technical solution, the operator can push the two cross plates 28, and the cross plates 28 slide in the inner cavity of the connecting plate 27. The cross plates 28 drive the connecting springs 29 to stretch, and the cross plates 28 slide in the inner cavity of the secondary chute 24 until the two cross plates 28 are displaced to the inner cavity of the main chute 30. The operator can push the connecting plate 27 to move upward or downward, and the connecting plate 27 drives the cross plates 28 to slide in the inner cavity of the main chute 30. After reaching the corresponding position, the cross plates 28 are released. Under the action of the resetting force of the connecting springs 29, the connecting springs 29 push the cross plates 28 to be clamped into the inner cavity of the secondary chute 24. The operator controls the deformation height of the top plate 22 to compress the reset spring 23 downward by adjusting the height of the connecting plate 27 in the inner cavity of the collecting trough 7, so that the operator can adjust the weight of the material collected by the collection box at a single time, thereby avoiding quality problems caused by excessive materials.
[0029] Working principle: the operator puts the material into the inner cavity of the grinding cylinder 2 through the feed port 3. After the grinding cylinder 2 grinds the material, it is discharged into the storage tank 5 through the discharge port 4. Then the operator turns on the motor 9, so that the motor 9 drives the screw rod 10 of the output shaft to rotate. The sliding plate 11 slides on the outer surface of the screw rod 10 as the screw rod 10 rotates. The sliding plate 11 drives the connecting rod 12 to move synchronously. The connecting rod 12 drives the scraper 14 to slide in the inner cavity of the storage tank 5, and pushes the abrasive placed in the storage tank 5 to the top of the guide plate 6, and slides along the top of the guide plate 6 to the top of the collecting tank 7, and then enters the collecting box for collection. Under the action of gravity, the collecting box pushes the top plate 22 to move downward, and the top plate 22 gradually compresses the reset spring 23 until the bottom of the top contacts the conductive rod 25 on one side. The top drives the conductive rod 25 to move downward and gradually compresses the stop spring 26. The two conductive rods 25 are no longer in contact, so that the power supply is cut off, the motor 9 stops rotating, and the scraper 14 no longer pushes the material into the collecting box.
[0030] Finally, it should be noted that the above embodiments are only used to illustrate the technical solution of the utility model, rather than to limit it. Although the utility model has been described in detail with reference to the aforementioned embodiments, ordinary technicians in this field should understand that they can still modify the technical solutions recorded in the aforementioned embodiments, or replace some or all of the technical features therein with equivalents.
