Description

Technical Field

[0001] The utility model relates to the technical field of concrete weighing, in particular to a concrete weighing device for concrete production. Background Art

[0002] In the process of concrete production, different sands, aggregates, etc. need to be mixed according to weight ratio. When producing concrete, the concrete raw material sand needs to be weighed and discharged. The Chinese utility model patent, authorization announcement number "CN220840911U", discloses a concrete weighing device for concrete production, including a weighing bucket, a turning mechanism is provided at the bottom of the weighing bucket, and a scraping mechanism is provided at the bottom of the weighing bucket; the scraping mechanism includes a U-shaped frame, and the bottom of the inner surface of the U-shaped frame is fixedly connected to a drive motor, and the top end of the output shaft of the drive motor is fixedly connected to a multi-stage hydraulic cylinder through a coupling.

[0003] The above technical solution rotates the servo motor in the flipping mechanism to a certain angle after weighing, driving the weighing hopper to tilt to a certain angle to dump the material. Then, with the cooperation of the scraping mechanism, the motor is driven to rotate, and the multi-stage hydraulic cylinder is extended and retracted, driving the scraper to move and rotate in the weighing hopper to scrape the material. Due to the setting of the spring, the scraper is close to the inner wall of the weighing hopper, so that the material attached to the weighing hopper is scraped off and flows out of the weighing hopper, which greatly reduces the influence of the ingredients adhering to the inner wall of the weighing hopper on the accuracy of the proportion. However, when the concrete powder falls to the external hopper truck, the discharge pipe is far away from the interior of the hopper truck, and it is easy for the powder to fly. This not only pollutes the environment, but also causes the accuracy of the measured concrete powder data to be poor. Utility Model Content

[0004] The purpose of the present utility model is to solve at least one of the technical problems existing in the prior art and to provide a concrete weighing device for concrete production, which can solve the problem that when concrete powder is dropped onto an external hopper truck, the discharge pipe is far away from the interior of the hopper truck, which makes it easy for the powder to fly, which not only pollutes the environment but also leads to poor accuracy of the measured concrete powder data.

[0025] See also Figure 1-4 , the utility model provides a technical solution: a concrete weighing device for concrete production, comprising a weighing tank 1, the upper end of which is welded with a feed pipe;

[0026] The weighing tank 1 is provided with a moisture removal weighing assembly, which includes a housing 2, two pressure sensors 7, a heating ring 14, a second pipe 15 and an auger 16. The second pipe 15 is welded to the lower end of the weighing tank 1, and the heating ring 14 is fixedly sleeved on the surface of the second pipe 15. The upper ends of the two pressure sensors 7 are fixedly connected to the housing 2, and the lower ends of the two pressure sensors 7 are fixedly connected to the inside of the weighing tank 1.

[0027] A blanking assembly is provided at the lower end of the shell 2, which includes an electric push rod 3, a connecting rod 4, a pipe 5 and a sleeve 6. The pipe 5 is welded to the lower end of the shell 2, and the sleeve 6 slides along the surface of the pipe 5. The connecting rod 4 is welded to the sleeve 6, and the other end of the connecting rod 4 is connected to the lower end of the electric push rod 3, and the upper end of the electric push rod 3 is connected to the bottom of the shell 2.

[0028] The surface of the weighing tank 1 is rotatably connected to a sleeve shaft 12 , and the surface of the sleeve shaft 12 is fixedly sleeved with a gear 10 .

[0029] A plurality of breaking rods 13 are fixedly sleeved on the surface of the sleeve shaft 12, and a motor 9 is screwed onto the upper end of the weighing tank 1.

[0030] The output shaft key pin of motor 1 9 is installed with motor gear 8, and motor gear 8 is engaged with gear 10.

[0031] The interior of the sleeve shaft 12 is rotatably connected to a rotating shaft 17 , and a second motor 11 is mounted on the surface of the weighing tank 1 via screws, and the output shaft of the second motor 11 is connected to the upper end of the rotating shaft 17 .

[0032] The lower end of the sleeve shaft 12 is fixedly connected to the auger 16 , and the auger 16 is arranged inside the pipe 2 15 .

[0033] It should be noted that the housing 2 does not support the heating ring 14 .

[0034] When concrete powder needs to be weighed;

[0035] First, pour the concrete powder into the weighing tank 1 through the feeding pipe at the upper end of the weighing tank 1, and then start the motor 9. The start of the motor 9 drives the motor gear 8 to rotate, and the rotation of the motor gear 8 drives the gear 10 to rotate. The rotation of the gear 10 drives the sleeve shaft 12 to rotate, and the rotation of the sleeve shaft 12 drives multiple breaking rods 13 to rotate to break up the concrete powder inside the weighing tank 1.

[0036] Secondly, the broken concrete powder enters the interior of pipe 2 15, and then the heating ring 14 is started to heat the broken powder inside pipe 2 15. At the same time, motor 2 11 is started. The start of motor 2 11 drives the rotating shaft 17 to rotate, and the rotation of the rotating shaft 17 drives the auger 16 to rotate and drive the powder to move downward to the interior of the shell 2.

[0037] Finally, the electric push rod 3 is started, and the start of the electric push rod 3 drives the connecting rod 4 to move downward. The downward movement of the connecting rod 4 drives the sleeve 6 to move downward until it is close to the hopper car. Subsequently, the powder inside the shell 2 enters the hopper car through the pipe 5 and the sleeve 6.

[0038] The amount of powder is observed by observing the readings of the two pressure sensors 7.

[0039] By setting the electric push rod 3 in the unloading assembly, the electric push rod 3 can drive the sleeve 6 to move downward to the inside of the hopper car, thereby reducing the distance between the sleeve 6 and the hopper car, reducing the possibility of powder flying at the sleeve 6 and polluting the environment, thereby improving the accuracy of the data measured by the two pressure sensors 7.

[0040] Since the concrete powder has good water absorption, if the concrete raw materials are weighed directly, there will be a lot of moisture. By setting the heating ring 14 and the auger 16 in the moisture removal weighing component, the auger 16 can extend the contact time between the powder and the pipe 2 15, and the heating ring 14 can heat the pipe 2 15, thereby reducing the moisture content in the concrete powder, that is, improving the accuracy of subsequent weighing.

[0041] Working principle:

[0042] When concrete powder needs to be weighed;

[0043] First, pour the concrete powder into the weighing tank 1 through the feeding pipe at the upper end of the weighing tank 1, and then start the motor 9. The start of the motor 9 drives the motor gear 8 to rotate, and the rotation of the motor gear 8 drives the gear 10 to rotate. The rotation of the gear 10 drives the sleeve shaft 12 to rotate, and the rotation of the sleeve shaft 12 drives multiple breaking rods 13 to rotate to break up the concrete powder inside the weighing tank 1.

[0044] Secondly, the broken concrete powder enters the interior of pipe 2 15, and then the heating ring 14 is started to heat the broken powder inside pipe 2 15. At the same time, motor 2 11 is started. The start of motor 2 11 drives the rotating shaft 17 to rotate, and the rotation of the rotating shaft 17 drives the auger 16 to rotate and drive the powder to move downward to the interior of the shell 2.

[0045] Finally, the electric push rod 3 is started, and the start of the electric push rod 3 drives the connecting rod 4 to move downward. The downward movement of the connecting rod 4 drives the sleeve 6 to move downward until it is close to the hopper car. Subsequently, the powder inside the shell 2 enters the hopper car through the pipe 5 and the sleeve 6.

[0046] The embodiments of the present invention are described in detail above with reference to the accompanying drawings. However, the present invention is not limited to the above embodiments. Various changes can be made within the scope of knowledge possessed by ordinary technicians in the technical field without departing from the purpose of the present invention.
