Description

Technical Field

[0001] The utility model relates to the technical field of metering devices, in particular to a material metering device. Background Art

[0002] Dry-mixed mortar is also called dry-powdered mortar. Dry-mixed mortar refers to a granular or powdered material that is physically mixed in a certain proportion with dried and sieved aggregates (such as quartz sand), inorganic cementitious materials (such as cement) and additives (such as polymers). It is transported to the construction site in bags or bulk and can be used directly after adding water and mixing. After the production of dry-mixed mortar is completed, it needs to be measured and packaged.

[0003] In the patent with authorization announcement number CN219584568U, a dry mortar metering device is disclosed. The disclosed metering device is described as "when in use, it is only necessary to pour the dry mortar into the funnel-shaped shell, and then open the valve, the dry mortar will fall into the storage box along the discharge pipe. When the weight of the dry mortar in the storage box increases, it will drive the spring to move downward, which will cause the support plate to move downward. The support plate moves downward for a certain distance and can block the discharge pipe through the quantitative blocking mechanism, thereby closing the discharge pipe and the valve, and pouring out the dry mortar in the storage box for packaging." Although it can complete the metering of dry mortar, the flexibility of the storage box is poor. After the dry mortar in the storage box reaches the metering value, it needs to be shut down for a long time. It is necessary to wait until the staff pours out the dry mortar in the storage box and completes the packaging before continuing the next metering operation. This wastes time and makes the metering efficiency low, and it is difficult to meet the needs of large-scale dry mortar metering. Utility Model Content

[0004] The utility model provides a material metering device to solve the problem that the existing metering device has low metering efficiency and is difficult to meet the metering needs of large quantities of dry mortar.

Specific embodiments

[0024] The following will clearly and completely describe the technical solutions in the embodiments of the present invention with reference to the drawings in the embodiments of the present invention. Obviously, the described embodiments are only some embodiments of the present invention, rather than all embodiments. Based on the embodiments of the present invention, all other embodiments obtained by those of ordinary skill in the art without creative efforts belong to the scope of protection of the present invention.

[0025] Figure 1 And Figure 2 Both are the overall structure diagrams of the present invention. As shown in the figure, the material metering device includes a mounting rack 3 and a base 5. A controller 4 is installed on the outer wall of the mounting rack 3, and a feeding cylinder 1 is installed on the mounting rack 3. One side of the top of the feeding cylinder 1 is provided with a feeding hopper 2, and the other side of the bottom of the feeding cylinder 1 is connected to a blanking pipe 7. And a material guiding assembly is provided on the feeding cylinder 1.

[0026] Among them, refer to Figure 3As shown in the figure, the material guiding assembly includes a first motor 10 and a material guiding auger 12. The first motor 10 is installed at one end of the feeding cylinder 1, and the material guiding auger 12 is installed at the output end of the first motor 10 through a connecting shaft, and the material guiding auger 12 is located inside the feeding cylinder 1.

[0027] As described above, the dry-mixed mortar is added into the feeding cylinder 1 from the feeding hopper 2, and the material guiding auger 12 is driven to rotate by the output end of the first motor 10 for material guiding, which can ensure the uniformity of feeding and further mix the dry-mixed mortar evenly.

[0028] Furthermore, bottom plates 19 are fixedly arranged at both bottom ends of the mounting frame 3. Mounting holes are formed in the bottom plates 19. By passing expansion bolts through the mounting holes, the bottom plates 19 can be fixed, thereby ensuring the stability of the mounting frame 3.

[0029] Refer to Figure 1 and Figure 2 As shown in the figure, the base 5 is arranged below the feeding cylinder 1, and a circular support plate 6 is rotatably arranged above the base 5. Six material receiving barrels 8 are arranged in a circular array on the upper end surface of the circular support plate 6. A gravity sensor 11 is installed at the inner bottom of the material receiving barrel 8. The gravity sensor 11 is electrically connected to the controller 4. A discharge pipe 9 is obliquely connected downward at the lower end of the outer wall of the material receiving barrel 8. Under the orderly rotation of the circular support plate 6, the material receiving barrel 8 can be positioned directly below the blanking pipe 7 for receiving the materials falling from the blanking pipe 7. Solenoid valves 18 are installed on both the blanking pipe 7 and the discharge pipe 9, and the solenoid valves 18 are electrically connected to the controller 4.

[0030] Among them, refer to Figure 4 and Figure 5 As shown in the figure, an installation groove 16 is formed in the middle of the upper end surface of the base 5. A second motor 13 is installed in the middle of the installation groove 16. The top end of the second motor 13 is connected to the middle of the lower end surface of the circular support plate 6 through a speed reducer.

[0031] An annular sliding groove 17 is formed near the edge of the upper end surface of the base 5. An annular sliding strip 14 is fixed near the edge of the lower end surface of the circular support plate 6. The annular sliding strip 14 is fitted in the annular sliding groove 17.

[0032] By the rotation of the annular sliding strip 14 in the annular sliding groove 17, the stability of the rotation of the circular support plate 6 can be ensured, and the annular sliding strip 14 plays a supporting role to reduce the load on the output end of the second motor 13.

[0033] Based on the above technical solutions:

[0034] During specific use, first, the controller 4 is used to open the solenoid valve 18 on the blanking pipe 7 and close the solenoid valve 18 on the discharge pipe 9. After the dry-mixed mortar to be metered is put into the feeding cylinder 1, the guiding component is used to guide the dry-mixed mortar to the upper port of the blanking pipe 7, and then it falls through the blanking pipe 7 into the lower material receiving bucket 8. When the gravity sensor 11 measures that the gravity in the material receiving bucket 8 reaches the preset value, it feeds back to the controller 4. The controller 4 promptly closes the solenoid valve 18 on the blanking pipe 7, and then starts the second motor 13 in the installation groove 16 to rotate the circular support plate 6 by one-sixth of a turn, so that the next material receiving bucket 8 is positioned directly below the blanking pipe 7. Subsequently, the solenoid valve 18 on the blanking pipe 7 is opened, and the metering operation is repeated.

[0035] Among them, when the empty material receiving bucket 8 is used for metering the dry-mixed mortar, the staff can take out the dry-mixed mortar in other metered material receiving buckets 8 for packing, which does not affect the normal metering operation and does not require long-term shutdown, greatly improving the metering efficiency of the dry-mixed mortar and meeting the needs of large-batch dry powder mortar metering.

[0036] Secondly, when taking out the dry-mixed mortar in the metered material receiving bucket 8, the controller 4 can be used to open the solenoid valve 18 on the discharge pipe 9, and it can be collected through the inclined discharge pipe 9. When some dry-mixed mortar cannot be discharged from the discharge pipe 9, the material receiving bucket 8 can be tilted to pour out the dry-mixed mortar.

[0037] Furthermore, a plurality of balls 15 are rotatably installed on the lower end surface of the annular slide bar 14, and the balls 15 are in contact with the bottom of the annular chute 17.

[0038] Specifically, the arranged balls 15 can reduce the friction force, thereby reducing the output intensity of the second motor 13.

[0039] The above are only the preferred embodiments of the present invention and are not intended to limit the present invention. Any modifications, equivalent replacements, improvements, etc. made within the spirit and principle of the present invention shall be included within the protection scope of the present invention.
