DETAILED DESCRIPTION OF THE EMBODIMENTS

[0021] The following description is used to disclose the present utility model so that those skilled in the art can implement the present utility model. The preferred embodiments described below are only examples, and those skilled in the art can think of other obvious variations.

[0022] Refer to Figure 1 and Figure 2As shown in the figure, a conveying device for producing dry-mixed mortar powder includes a weighing tank 1 and a mixing tank feed pipe 4. The lower end of the weighing tank 1 is fixedly connected with a blanking pipe 5. The other end of the blanking pipe 5 is fixedly connected with a conveying pipeline 2. An electronic batcher 6 is arranged on the blanking pipe 5. A non-woven bag 3 is sleeved at the connection between the conveying pipeline 2 and the mixing tank feed pipe 4. A partition 7 is fixedly connected inside the weighing tank 1. A plurality of uniformly distributed filter holes 18 are formed through the upper end of the partition 7. An electromagnet 8 is fixedly connected to the lower end of the partition 7. A fixed cylinder 9 is fixedly connected to the lower end of the partition 7 outside the electromagnet 8. A fixing plate 10 is fixedly connected to the lower end of the fixed cylinder 9. A metal block 11 is slidably connected inside the fixed cylinder 9. A connecting rod 12 is fixedly connected to the lower end of the metal block 11. The other end of the connecting rod 12 penetrates through the upper end of the fixing plate 10 and is fixedly connected with a rubber plug 13. The lower end of the metal block 11 is located outside the connecting rod 12, and four uniformly distributed guide rods 16 are fixedly connected. The other end of the guide rod 16 penetrates through the upper end of the fixing plate 10 and is fixedly connected with a limiting seat 17. Four uniformly distributed support frames 14 are fixedly connected to the outer surface of the connecting rod 12. The other end of the support frame 14 is fixedly connected with a discharge door 15.

[0023] Further, the rubber plug 13 is inserted into the inside of the blanking pipe 5.

[0024] Further, the discharge door 15 is inserted between the weighing tank 1 and the fixing plate 10.

[0025] Further, a feed door 22 is hinged to the upper end of the weighing tank 1.

[0026] Further, a first rotating shaft 20 is rotatably connected between the weighing tank 1 and the partition 7. A scraping plate 19 is fixedly connected to the outer surface of the first rotating shaft 20. The lower end of the scraping plate 19 is slidably connected to the upper end of the partition 7. The inner and outer sides of the scraping plate 19 are slidably connected to the inner wall of the weighing tank 1. A first motor 21 for driving the first rotating shaft 20 to rotate is fixedly installed at the upper end of the weighing tank 1.

[0027] Further, by rotating and opening the feed door 22, raw materials can be added to the weighing tank 1. After the raw materials enter the inside of the weighing tank 1, by driving the first rotating shaft 20 to rotate through the first motor 21, the scraping plate 19 can be driven to push the raw materials to move. The raw materials will leak out through the filter holes 18 on the partition 7, thereby removing large-particle impurities in the raw materials and helping to improve the quality of the product.

[0028] Further, by energizing the electromagnet 8, the metal block 11 can be adsorbed. When the metal block 11 is adsorbed by the electromagnet 8, it will drive the connecting rod 12 to move upward. When the connecting rod 12 moves upward, it will drive the discharge door 15 and the rubber plug 13 to move upward. At this time, the raw material will fall onto the surface of the fixed plate 10 and into the blanking pipe 5, and then be transported to the inside of the conveying pipe 2 through the blanking pipe 5. When the raw material passes through the blanking pipe 5, the electronic batcher 6 will monitor the amount of raw material passing through the blanking pipe 5. When the amount of transported raw material reaches the preset value, the electromagnet 8 is powered off. At this time, the metal block 11 will fall under its own gravity, thereby driving the discharge door 15 to close, and at the same time, the rubber plug 13 will block the blanking pipe 5, thereby controlling the amount of transported raw material, reducing the proportioning error caused by inaccurate feeding amount, and helping to improve the consistency and quality of the product.

[0029] Referring to Figure 1 and Figure 3 As shown, a second rotating shaft 23 is rotatably connected to the inside of the conveying pipe 2. A spiral conveyor blade 24 is fixedly connected to the outer surface of the second rotating shaft 23. A second motor 25 for driving the second rotating shaft 23 to rotate is fixedly installed at the right end of the conveying pipe 2.

[0030] Further, by driving the second rotating shaft 23 to rotate through the second motor 25, the spiral conveyor blade 24 can be driven to convey the raw material falling into the inside of the conveying pipe 2. Conveying through the conveying pipe 2 can reduce the pollution to the processing environment caused by dust flying compared with conveying by a conveyor belt.

[0031] Referring to Figure 1 、 Figure 3 and Figure 4 As shown, fastening grooves 26 are provided on the outer surface of the conveying pipe 2 on one side close to the mixing tank feed pipe 4 and on the outer surface of the mixing tank feed pipe 4 on one side close to the conveying pipe 2. A tightening belt 27 is sleeved on the outer surface of the fastening groove 26 outside the non-woven fabric bag 3.

[0032] Further, by connecting the conveying pipe 2 and the mixing tank feed pipe 4 through the non-woven fabric bag 3, the dust diffusion caused when the raw material is discharged from the conveying pipe 2 can be reduced. By sleeving the tightening belt 27 on the outside of the non-woven fabric bag 3 and tightening the tightening belt 27 in the fastening groove 26, the non-woven fabric bag 3 can be fixed to prevent it from falling off. At the same time, the design of the tightening belt 27 facilitates the disassembly and replacement of the non-woven fabric bag 3.

[0033] Working principle: When in use, open the feeding door 22 to add raw materials into the weighing tank 1. After the raw materials enter the interior of the weighing tank 1, drive the first rotating shaft 20 to rotate through the first motor 21, which can drive the scraper 19 to push the raw materials to move. The raw materials will leak out through the filter holes 18 on the partition plate 7, thereby removing large-particle impurities in the raw materials. Then, set the preset value of the electronic metering device 6 according to the processing requirements. Next, energize the electromagnet 8 to adsorb the metal block 11. After the metal block 11 is adsorbed by the electromagnet 8, the discharge door 15 will open, and at the same time, the rubber plug 13 will be pulled out from the feeding pipe 5. At this time, the raw materials will fall along the surface of the fixing plate 10 into the feeding pipe 5, and then enter the conveying pipeline 2. The electronic metering device 6 will monitor the amount of raw materials passing through the feeding pipe 5. The raw materials transported into the interior of the conveying pipeline 2 through the feeding pipe 5 will be transported by the spiral conveyor blade 24 under the drive of the second motor 25 and the second rotating shaft 23. When the electronic metering device 6 monitors that the feeding amount reaches the preset value, the electromagnet 8 is powered off. At this time, the metal block 11 will fall under its own gravity, thereby driving the discharge door 15 to close, and at the same time, the rubber plug 13 will block the feeding pipe 5, so as to control the amount of transported raw materials, which can reduce the proportioning error caused by inaccurate feeding amount, and help improve the consistency and quality of the product. After the electromagnet 8 is powered off, the second motor 25 will still drive the spiral conveyor blade 24 to operate for a period of time to ensure that all the raw materials in the conveying pipeline 2 are transported completely.

Those skilled in the art should understand that the present invention is not limited by the above embodiments.
