Description

Technical Field

[0001] This utility model relates to the field of concrete production, specifically a cement metering hopper for weighing concrete powder. Background Technology

[0002] A cement metering hopper is a device used to measure cement and is widely used in various industries such as construction and coal mining. In concrete mixing plants, it is a key component for achieving accurate cement measurement and ensuring concrete quality; similar metering hoppers are also commonly used in quantitative hopper loading equipment in coal production.

[0003] In existing technologies, especially in the concrete powder weighing industry, weighing is done using a measuring hopper. However, when concrete powder is added to the hopper, a large amount of dust is generated. This dust floats in the air, easily polluting the air and affecting the quality of the working environment, which is not environmentally friendly. Furthermore, after the concrete powder is weighed, some of it tends to adhere to the inner wall of the hopper during the discharge process, making it difficult to discharge and resulting in waste of concrete powder. Utility Model Content

Detailed Implementation

[0023] The technical solutions of the present utility model will be clearly and completely described below with reference to the accompanying drawings of the embodiments of the present utility model. Obviously, the described embodiments are only some embodiments of the present utility model, and not all embodiments. All other embodiments obtained by those skilled in the art based on the embodiments of the present utility model without creative effort are within the protection scope of the present utility model.

[0024] Please see Figure 1-4 This utility model provides a cement measuring hopper for weighing concrete powder, which includes a measuring hopper body 1 and a base 6. The base 6 is located below the measuring hopper body 1. A vacuum cleaner 15 is fixed on the outside of the measuring hopper body 1, and an annular pipe 16 communicating with the vacuum cleaner 15 is provided above the measuring hopper body 1. Several upwardly inclined dust collection hoods 17 are connected to the inner circumference of the annular pipe 16.

[0025] During the process of adding concrete powder into the measuring hopper body 1, the vacuum cleaner 15 is activated. Since multiple dust hoods 17 are installed in the annular pipe 16, after the vacuum cleaner 15 starts working, the dust hoods 17 absorb the dust and then discharge it into the vacuum cleaner 15 through the annular pipe 16. This facilitates the timely absorption and treatment of dust that floats out of the measuring hopper body 1, preventing a large amount of dust from floating into the air, thereby reducing environmental pollution and ensuring the quality of the working environment, making it more environmentally friendly.

[0026] In this embodiment, a weighing frame 19 is provided above the base 6, and a weighing sensor 8 is connected between the weighing frame 19 and the base 6. Support rods 4 are fixed on both the left and right sides of the upper end of the support plate 5. The measuring hopper body 1 is fixed between the two support rods 4. A weighing display screen 18 is installed on the outside of one of the support rods 4. The weighing display screen 18 is connected to the weighing sensor 8.

[0027] The weighing sensor 8 weighs all the structures on the weighing frame 19. When concrete powder is loaded into the hopper body 1, the weight increases, so the weighing frame 19 will press the weighing sensor 8. The weighing sensor 8 can accurately weigh the concrete powder in the hopper body 1. The weight value is displayed on the weighing display screen 18, which achieves the effect of convenient measurement.

[0028] In this embodiment, several telescopic rods 7 are connected between the weighing frame 19 and the base 6.

[0029] By setting multiple telescopic rods 7 between the base plate 6 and the weighing frame 19 for support, it is beneficial to ensure the stability of the support of the weighing frame 19.

[0030] In this embodiment, a support plate 5 is provided above the weighing frame 19, and a shaking drive assembly is provided between the support plate 5 and the weighing frame 19. The shaking drive assembly includes guide rods 13, sliding plates 12, return springs 14, motors 9, impact balls 10, and semicircular blocks 11. There are two guide rods 13, which are distributed left and right and fixed inside the weighing frame 19. There are two sliding plates 12, which are distributed left and right and fixed at the lower end of the support plate 5. The sliding plates 12 are slidably sleeved with the adjacent guide rods 13. Next, two return springs 14 are provided and connected to the outer sides of the two sliding plates 12, and the ends of the return springs 14 are connected to the inner side wall of the weighing frame 19. The motor 9 is fixed to the middle of the upper end of the weighing frame 19. Two impact balls 10 are provided and connected to the power end of the motor 9. The semicircular block 11 is fixed to the lower end of the support plate 5, and the impact ball 10 corresponds to the semicircular block 11. The lower end of the measuring hopper body 1 is connected to the discharge valve 2, and the discharge port of the discharge valve 2 is connected to the discharge pipe 3.

[0031] In operation, the concrete powder weighing hopper of this utility model first opens the discharge valve 2, and the concrete powder in the hopper body 1 is discharged through the discharge valve 2 and the discharge pipe 3. During the discharge process, the motor 9 drives the impact ball 10 to rotate, and the impact ball 10 will continuously hit the semicircular block 11, so it will drive the semicircular block 11, the support plate 5 and the sliding plate 12 to move to the left. At the same time, the support plate 5 drives the support rod 4 and the hopper body 1 to move to the left together. When the sliding plate 12 moves to the left along the guide rod 13, it will compress or stretch the return spring 14. Then, the elastic force of the return spring 14 will drive the sliding plate 12 to move to the right along the guide rod 13, thereby driving the support plate 5, the support rod 4 and the hopper body 1 to move to the right together.

[0032] In summary, by repeating this process, the measuring hopper body 1 will move back and forth and shake, which helps to cleanly discharge the powder adhering to the inner wall of the measuring hopper body 1, effectively reducing the waste of concrete powder.

[0033] Although embodiments of the present invention have been shown and described, it will be understood by those skilled in the art that various changes, modifications, substitutions and alterations can be made to these embodiments without departing from the principles and spirit of the present invention, the scope of which is defined by the appended claims and their equivalents.
