[0001] The present invention relates to the field of building material processing equipment, and specifically to an efficient weighing device for concrete aggregates. Background Art
[0002] With the continuous improvement of the level of building industrialization and the large-scale popularization and application of ready-mixed concrete, construction units have put forward higher requirements for automation and precision in the control of raw materials during the concrete preparation process. Especially in the aggregate link, the attention to its mixing ratio accuracy, mixing uniformity, and material handling efficiency has been increasing. As the main component of concrete, the quality and mixing ratio of aggregates directly affect the physical properties of concrete and the engineering quality. In structural projects such as residential buildings, bridges, and high-rise buildings, the strength grade, fluidity, and construction performance of concrete largely depend on the particle size distribution of aggregates, moisture content control, and the mixing uniformity among different materials.
[0003] In the prior art, the aggregate processing system generally has problems such as structural separation and low collaborative efficiency.

The scraper always runs in contact with the tank wall under the action of elastic force, effectively removing the residual aggregates attached during the stirring process. Compared with the existing solutions that rely on manual or timed cleaning, this structure realizes the automatic cleaning inside the tank body, reduces the maintenance frequency, and improves the continuous operation ability of the equipment and the system stability.

[0034] Please refer to the attached Figure 1 - attached Figure 5 Figure, the anti-blocking mechanism includes the first motor 12. The first motor 12 is fixedly connected to the outside of the first discharge pipe 6 through the mounting plate 13. The output end of the first motor 12 is fixedly connected with the driving wheel 15. Inside the weighing hopper 1, the first rotating shaft 2 and the second rotating shaft 18 are rotatably connected. On the outside of both the first rotating shaft 2 and the second rotating shaft 18, two bottom plates 17 are fixedly connected. One end of the second rotating shaft 18 passing through the weighing hopper 1 is fixedly connected with the first driven wheel 14. One end of the first rotating shaft 2 passing through the weighing hopper 1 is fixedly connected with the second driven wheel 16. On the side of the driving wheel 15 away from the first motor 12, a connecting shaft 26 is fixedly connected. The connecting shaft 26 is rotatably connected inside the weighing hopper 1.

The bottom plates 17 are rotatably connected inside the weighing hopper 1.
[0035] Specifically, the first motor 12 serves as the power source of the mechanism and is stably installed on the outside of the first discharge pipe 6 through the mounting plate 13. Its output end is fixedly connected to the driving wheel 15, which is used to drive the entire anti-blocking mechanism to operate. The first rotating shaft 2 and the second rotating shaft 18 arranged inside the weighing hopper 1 are respectively used to support and drive the bottom plate 17 to rotate. Two bottom plates 17 are fixedly connected to the outside of each of the two rotating shafts. During the rotation process, the bottom plate 17 can continuously disturb the aggregate in the discharge area, thereby breaking up the materials that are prone to form an arched accumulation and preventing blockage. The second rotating shaft 18 penetrates one end of the weighing hopper 1 and is fixedly connected to the first driven wheel 14, and the first rotating shaft 2 penetrates the other end of the weighing hopper 1 and is fixedly connected to the second driven wheel 16. The two groups of driven wheels and the driving wheel 15 form a synchronous transmission system. The driving wheel 15 is connected to a connecting shaft 26 on the side away from the first motor 12. The connecting shaft 26 is arranged inside the weighing hopper 1 and can rotate freely, thus ensuring the smooth transmission of power. The driving wheel 15 is located between the first driven wheel 14 and the second driven wheel 16 and meshes with both of them to achieve double-axis linkage drive. When the first motor 12 is started, the driving wheel 15 drives the first driven wheel 14 and the second driven wheel 16 to rotate synchronously, and then drives the first rotating shaft 2 and the second rotating shaft 18 to rotate, so that the bottom plate 17 rotates and disturbs inside the weighing hopper 1, effectively breaking up the aggregate, ensuring that the aggregate smoothly passes through the first discharge pipe 6 and falls into the mixing tank 8, achieving the purpose of anti-blocking.
[0036] Please refer to the attached Figure 1 attachment Figure 6 , attachment Figure 7 , attachment Figure 8 and attachment Figure 9 . The mixing mechanism includes a second motor 22. The second motor 22 is installed on the top of the mixing tank 8. The output end of the second motor 22 is fixedly connected to a square rod 30. A sleeve 24 is slidably connected to the outside of the square rod 30. An inclined disk 31 is fixedly connected to the outside of the sleeve 24. A connecting rod 33 is fixedly connected to the inner top wall of the mixing tank 8. The connecting rod 33 is fixedly connected with an upper roller 32 and a lower roller 34 in sequence from top to bottom. A plurality of mixing rods 25 are fixedly connected to the outside of the sleeve 24. An anti-sticking component is arranged at one end of the mixing rod 25 away from the sleeve 24. A baffle 7 is fixedly connected to the top of the mixing tank 8. One end of the first discharge pipe 6 away from the weighing hopper 1 is located directly above the mixing tank 8. The inclined disk 31 is slidably connected between the upper roller 32 and the lower roller 34. The middle part of the sleeve 24 is a square hole. The mixing rod 25 is rotatably connected inside the mixing tank 8.
[0037] Specifically, the second motor 22 serves as the driving source of the stirring mechanism and is installed at the top of the stirring tank 8. Its output end is fixedly connected to the square rod 30, and the square rod 30 rotates under the drive of the second motor 22. A sleeve 24 is slidably connected to the outside of the square rod 30. The middle part of the sleeve 24 is provided with a square hole, which can cooperate with the square rod 30 to achieve rotation. An inclined disk 31 is fixedly connected to the outside of the sleeve 24, which is used to make the sleeve 24 generate a lifting motion under the constraint of the roller during rotation. A connecting rod 33 is fixedly connected to the inner top wall of the stirring tank 8. An upper roller 32 and a lower roller 34 are successively installed on the connecting rod 33 from top to bottom. The inclined disk 31 is slidably connected between the upper roller 32 and the lower roller 34. Under the drive of the second motor 22, the inclined disk 31 is guided by the upper roller 32 and the lower roller 34 during rotation, thereby driving the sleeve 24 to slide up and down regularly. A plurality of stirring rods 25 are fixedly connected to the outside of the sleeve 24. The stirring rods 25 are arranged along the circumference and are used to stir the aggregate in the stirring tank 8 during the up and down movement of the sleeve 24, realizing multi-directional mixing of the materials. An anti-sticking component is provided at one end of the stirring rod 25 away from the sleeve 24, which is used to remove the residual materials adhering to the tank wall during stirring, prevent the aggregate from sticking and depositing, and improve the stirring efficiency. The whole stirring rod 25 is rotatably connected inside the stirring tank 8 to ensure its stable operation. A baffle 7 is also fixedly connected to the top of the stirring tank 8, which is used to enable the aggregate raw materials to smoothly enter the stirring tank 8. One end of the first discharge pipe 6 away from the weighing hopper 1 is directly opposite to the upper part of the stirring tank 8, so that the weighed aggregate can accurately fall into the stirring tank 8, ensuring continuous and lossless material receiving process. The whole stirring mechanism realizes rapid, uniform and efficient stirring of the aggregate through the combined rotation and lifting.
[0038] Please refer to the attached Figure 1 attachment Figure 6 , attachment Figure 7 , attachment Figure 8 and attachment Figure 9 , the anti-sticking component includes a housing 23. The outside of the housing 23 is fixedly connected to one end of the stirring rod 25 away from the sleeve 24. A plurality of springs 29 are arranged inside the housing 23. A limiting plate 28 is slidably connected inside the housing 23. A scraping plate 27 is fixedly connected to the outside of the limiting plate 28. One side of the scraping plate 27 away from the limiting plate 28 penetrates through the housing 23 and abuts against the inner wall of the stirring tank 8. The scraping plate 27 is slidably connected inside the housing 23. One end of the spring 29 is fixedly connected to the side of the limiting plate 28 away from the scraping plate 27, and the other end of the spring 29 abuts against the inner wall of the housing 23.
[0039] Specifically, the outer shell 23 serves as the housing structure of the anti-sticking component. Its outer side is fixedly installed at one end of the stirring rod 25 away from the sleeve 24, playing a role in carrying and protecting the internal parts. Inside the outer shell 23, there is a sliding connection with a limiting plate 28, which is used to control the movement limit of the scraping plate 27 and transmit the elastic force of the spring 29. The outer side of the limiting plate 28 is fixedly connected with a scraping plate 27. One end of the scraping plate 27 away from the limiting plate 28 penetrates through the outer shell 23 and keeps elastic contact with the inner wall of the mixing tank 8, and is used to continuously scrape off the aggregate raw materials adhered to the tank wall during the stirring process. The scraping plate 27 is in a sliding connection state inside the outer shell 23, ensuring that it can adaptively expand and contract when impacted by the aggregate or when the tank wall is uneven, and maintain good contact. Inside the outer shell 23, there are multiple springs 29. One end of the spring 29 is fixedly connected to the side of the limiting plate 28 away from the scraping plate 27, and the other end abuts against the inner wall of the outer shell 23, providing continuous elastic force to push the limiting plate 28 to move towards the scraping plate 27, so that the scraping plate 27 always closely adheres to the inner wall of the mixing tank 8 for cleaning. The design structure of this anti-sticking component is reasonable, which can automatically remove the adhered raw materials during the stirring process, improve the mixing uniformity, reduce the cleaning frequency, and extend the service life of the equipment.
[0040] Working principle: When weighing the aggregate, the cross plate 11 arranged in the weighing hopper 1 divides its interior into four independent chambers. First, pour one kind of aggregate raw material into one of the chambers, and then the weighing pan 3 starts to weigh the aggregate. Then, add different kinds of aggregates into the other chambers in turn. Each time an aggregate is added, the weight displayed by the weighing pan 3 will gradually increase until all the required aggregates are added to the weighing hopper 1 according to the preset weight.
[0041] After the weighing is completed, start the first motor 12, and this motor drives the driving wheel 15 to rotate. Since the driving wheel 15 meshes with the first driven wheel 14 and the second driven wheel 16, the driven wheels rotate synchronously, and then drive the bottom plate 17 to rotate. During the rotation of the bottom plate 17, the aggregate raw materials in the weighing hopper 1 are discharged through the first discharge pipe 6 and enter the mixing tank 8 below. The rotating structure design of the bottom plate 17 can effectively prevent the aggregate from clogging at the discharge port.
[0042] When all the aggregates enter the mixing tank 8, start the second motor 22 to drive the square rod 30 to rotate. Since there is a square hole in the middle of the sleeve 24 that cooperates with the square rod 30, the sleeve 24 rotates synchronously. At the same time, the inclined disk 31 on the sleeve 24 is located between the upper roller 32 and the lower roller 34. During the rotation, the inclined disk 31 drives the sleeve 24 to slide up and down along the square rod 30 under the constraint of the rollers, thereby driving the stirring rod 25 to stir up and down, realizing the full mixing of the aggregates.
[0043] Meanwhile, the rotation of the sleeve 24 also drives the anti-sticking component connected to the stirring rod 25 to work. The scraper 27 in this component always fits against the inner wall of the mixing tank 8 under the elastic force of the spring 29, continuously removing the aggregate raw materials adhering to the tank wall during the stirring process to prevent material residue.
[0044] After the mixing is completed, the solenoid valve 20 is opened, and the stirred aggregate falls onto the conveyor belt 10 through the lower channel. The conveyor belt 10 transports the mixed and weighed aggregate to the subsequent process.
