Description

Technical Field

[0001] This invention relates to the field of concrete filling technology, specifically to an intelligent quantitative filling device for powder and its control method. Background Technology

[0002] Bottled concrete and bagged concrete are two different supply methods. Bottled concrete is usually supplied directly to the construction site via unloading tank trucks, eliminating the need for manual filling and handling, thus saving construction time and manpower. In addition, bottled concrete allows for more precise proportioning and quality control during the production process, ensuring the strength, stability, and durability of the concrete. Therefore, to avoid the cumbersome operation of subsequent metering by customers, precise quality control is often carried out in advance by using the metering device of the powder tank during the bottled process.

[0003] Because concrete powder silos are large in size, even with a metering device, the accuracy of the metering device cannot reach that of a small flow meter. To ensure the accuracy of the metering device, the size of the discharge valve needs to be controlled to be small enough. However, this will restrict the discharge speed of the concrete powder. Therefore, generally, the silo is not equipped with a metering device, and the vehicle of the material transport truck is the main calculation method. However, for the concrete demand of a single truck hopper or less, manual estimation is required. To address this, we propose an intelligent quantitative powder filling equipment and its control method. Summary of the Invention

[0028] (III) Beneficial Effects

[0029] Compared with the prior art, the present invention provides an intelligent quantitative filling device for powder and its control method, which has the following beneficial effects:

[0030] 1. This intelligent quantitative powder filling equipment and its control method, through the setting of powder tank, through the relative opening of baffle and leak, the rotation of blades in one revolution between them, realizes the quantitative feeding of powder in a single batch. First, the effect of the blades is more intuitive, and the amount of powder fed in a single batch is the same. Second, it replaces the monitoring method of flow meter, indirectly avoiding the installation cost and operation and maintenance cost of large flow meter.

[0031] 2. The intelligent quantitative powder filling equipment and its control method feature a split design for the powder tank and the feeding hopper, which can be assembled and transported separately. This reduces the transportation volume and cost to a certain extent. Furthermore, it facilitates the maintenance and replacement of the tank in the later stages, eliminating the need for overall maintenance and reducing the difficulty and cost of maintenance. Moreover, during the vibration process of the vibrating motor driving the feeding hopper, the entire tank is not vibrated to the maximum extent, resulting in a better vibration effect. This indirectly and effectively ensures the feeding speed of concrete powder. Attached Figure Description

[0050] To make the technical means, creative features, achieved objectives, and effects of this invention readily understandable, the invention will be further described below with reference to the accompanying drawings of the embodiments. Obviously, the described embodiments are merely some, not all, of the embodiments of this invention. All other embodiments obtained by those skilled in the art based on the embodiments of this invention without creative effort are within the scope of protection of this invention.

[0051] To address the shortcomings of existing technologies, such as Figure 1 As shown, the present invention provides a powder intelligent quantitative filling device. The powder tank 1 is movably connected to the feeding hopper 2 through the connecting component 3, and the vibration motor 4 is fixedly connected to the outer wall of the feeding hopper 2. The powder tank 1 is equipped with a support frame and is fixedly connected to it.

[0052] It should be noted that during the process of discharging concrete powder, the transport vehicle first moves to the bottom of the discharge hopper 2, and then the powder is discharged into the transport vehicle through the powder tank 1 and the discharge hopper 2. In this process, in order to avoid the need for subsequent estimation of the weight of concrete powder, it is necessary to discharge the concrete powder in a quantitative manner.

[0053] The powder tank 1 and the feeding hopper 2 are designed separately, which can be assembled and transported separately. This reduces the transportation volume and cost to a certain extent. It also makes it easier to maintain and replace the tank in the future, without the need for overall maintenance and replacement, thus reducing the difficulty and cost of maintenance. Furthermore, when the vibrating motor 4 drives the feeding hopper 2 to vibrate, it does not drive the entire tank to vibrate to the maximum extent, resulting in a better vibration effect. This indirectly and effectively ensures the feeding speed of concrete powder.

[0054] Specifically, such as Figures 2-5 As shown, a powder tank 1 for a powder intelligent quantitative filling device has a cylindrical structure for the tank body 11, and the outlet 15 is opened from the bottom of the tank body 11 in a semi-circular shape. The baffle 14 is fixedly connected to the inside of the tank body 11, and the blade 12 is respectively attached to the baffle 14 and the inside of the tank body 11. The blade 12 is fixedly connected to the bottom of the connecting shaft 13, and the top of the connecting shaft 13 is fixedly connected to the mechanical output end of the drive component.

[0055] It should be noted that the present invention is a powder intelligent quantitative filling equipment. Through the powder tank 1, during the process of discharging concrete, the concrete powder inside the tank 11 is distributed above the baffle 14 and on the side of the bottom of the tank 11 away from the outlet 15. In this state, the concrete powder cannot fall directly into the inside of the hopper 2. It needs to be discharged by rotating the blades 12 to drive the concrete powder to flow.

[0056] The rotation of the blade 12 is achieved by an external drive assembly connected to the connecting shaft 13. The drive assembly can consist of a motor and a speed reducer. The motor drives the speed reducer, and the speed reducer drives the blade 12 to rotate through the connecting shaft 13.

[0057] The rotation direction of the blade 12 is based on the movement direction of the blade 12 from the bottom of the tank 11 with a large opening to a small opening. During the process of the motor driving the reducer to drive the blade 12 to rotate through the connecting shaft 13, the bottom surface of the blade 12 directly acts on the concrete powder. In this process, the concrete powder falls through the sluice 15 into the discharge hopper 2, and then from the discharge hopper 2 into the hopper of the transport vehicle. The single quantitative discharge of concrete powder is achieved by rotating the blade 12 once.

[0058] Those skilled in the art will understand that the weight of powder dispensed in a single quantitative feeding corresponds to the size of the space between the blade 12 and the bottom of the tank 11. The larger the space between the blade 12 and the bottom of the tank 11, the more powder is dispensed in a single feeding.

[0059] Among them, the relative opening of the baffle 14 and the outlet 15 allows for the quantitative feeding of powder in a single operation by the rotation of the blade 12. Firstly, the effect of the blade 12 is more intuitive, and the amount of powder fed in a single operation is the same. Secondly, it replaces the monitoring method of the flow meter, indirectly avoiding the installation and maintenance costs of large flow meters.

[0060] In a preferred embodiment, the material is fed using a vibrating motor 4. During the high-frequency vibration generated by the vibrating motor 4, the powder inside the powder tank 1 and the hopper 2 flows faster, thereby increasing the feeding speed of the concrete powder. Specifically, as shown... Figure 7 As shown, a connecting component 3 for a powder intelligent quantitative filling device includes a connecting seat 31 fixedly connected to and communicating with the bottom end of the powder tank 1, and a connecting seat 32 fixedly connected to and communicating with the top end of the hopper 2. Both sides of the connecting seat 31 are fixedly connected to base rods 31-1, and both sides of the connecting seat 32 are fixedly connected to collars 32-1. The two collars 32-1 are respectively sleeved on the outer wall of the corresponding base rods 31-1, and the connecting seat 31 is movably connected to the top of the connecting seat 32 through two sets of base rods 31-1 and collars 32-1.

[0061] Two elastic elements 33 are symmetrically arranged on the left and right sides of the geometric center of the connecting seat 2 32, and the two elastic elements 33 are respectively fixedly connected to the corresponding limiting elements 34. The two limiting elements 34 are also respectively attached to the left and right sides of the connecting seat 2 32.

[0062] It should be noted that the present invention is an intelligent quantitative filling device for powder. Through the set connecting member 3, before or during the feeding process, the elastic member 33 is rotated between the connecting seat 1 31 and the connecting seat 2 32 to change the vibration state between the connecting seat 1 31 and the connecting seat 2 32. During this period, after the state of the elastic member 33 is changed, the elastic member 33 is limited by the limiting member 34.

[0063] Because the first connecting seat 31 is movably connected to the second connecting seat 32 through connecting parts such as the base rod 31-1 and the collar 32-1, during the process of feeding concrete powder, the high-frequency vibration of the vibration motor 4 causes the second connecting seat 32 to vibrate based on the high-frequency vibration of the first connecting seat 31.

[0064] The vibration state between the first connecting seat 31 and the second connecting seat 32 is changed by rotating the elastic element 33 by 90°, and the rotation of the elastic element 33 is restricted by the limiting element 34.

[0065] In the lateral vibration state, the amplitude of lateral vibration is smaller than that of vertical vibration. It is mainly used to adjust the position, distribution and uniformity of powder. In the vertical vibration state, vertical vibration usually has a higher frequency, that is, a shorter vibration period. It is mainly used to provide vertical force or energy for the vibration transmission, lifting or separation of objects.

[0066] Furthermore, such as Figure 8 As shown, in a connecting component 3 for a powder intelligent quantitative filling device, an elastic element 33 has an insert plate 331 inserted into and slidably connected to a sleeve plate 332. Multiple springs 333 are fixedly connected to the inner bottom of the sleeve plate 332, and the ends of the multiple springs 333 away from the sleeve plate 332 are fixedly connected to the insert plate 331. Two limiting plates 334 are fixedly connected to the left and right sides of the sleeve plate 332, and the two limiting plates 334 are distributed left and right based on the geometric center of the insert plate 331 and the sleeve plate 332.

[0067] Furthermore, and such Figure 9 As shown, in a connecting component 3 for a powder intelligent quantitative filling device, a limiting member 34 has a connecting rod 341, one end of which is fixedly connected to a sleeve plate 332, and the upper end of which is based on the geometric center of the elastic member 33. The connecting rod 341 passes through the inside of the connecting seat 32 to its outside and is movably connected thereto. Multiple limiting balls 344 are fixedly connected to one end of a corresponding spring 343. The ends of the multiple springs 343 away from the limiting balls 344 are all fixedly connected to the connecting seat 32. The multiple limiting balls 344 are respectively opposite to the corresponding limiting grooves 342.

[0068] The connecting rod 341 is connected to a handwheel or the output end of a cam divider. The cam divider drives the connecting rod 341 to rotate periodically and intermittently, thereby changing the different vibration states of the elastic element 33 in conjunction with the connecting seat 32 and the elastic element 33.

[0069] It should be noted that the present invention is a powder intelligent quantitative filling equipment. By setting the elastic element 33 and the limiting element 34, during the process of changing the vibration state machine between the connecting seat 1 31 and the connecting seat 2 32, the connecting rod 341 is rotated by 90°, and the connecting rod 341 drives the sleeve plate 332 to rotate, so as to realize the rotation of the elastic element 33 as a whole.

[0070] During the process of the elastic element 33 rotating through the limiting member 34, the rotation of the elastic element 33 is restricted by multiple sets of springs 343 and limiting balls 344 in conjunction with the limiting groove 342 opened on the connecting rod 341.

[0071] When the connecting rod 341 is subjected to external force, because the limiting ball 344 is a spherical structure, during the rotation of the connecting rod 341 after being subjected to external force, multiple limiting balls 344 are compressed, and correspondingly, multiple springs 343 are simultaneously compressed.

[0072] As the connecting rod 341 rotates, the second spring 343 is compressed and possesses elastic potential energy. After the connecting rod 341 rotates 90°, the second spring 343 needs to release its elastic potential energy to drive the corresponding limiting ball 344 to engage with the corresponding limiting groove 342, thereby limiting the rotation of the connecting rod 341 and indirectly achieving the engagement of the elastic element 33.

[0073] The limiting grooves 342 on the connecting rod 341 are formed in groups of four based on the geometric center of the connecting rod 341. Therefore, the limiting engagement can be achieved regardless of whether the connecting rod 341 rotates 90° clockwise or counterclockwise.

[0074] like Figure 10 In the state shown, the two limiting plates 334 are respectively abutted against the opposite sides of the horizontal direction between the first connecting seat 31 and the second connecting seat 32, thereby limiting the horizontal movement direction between the first connecting seat 31 and the second connecting seat 32. In this state, after being subjected to the external action of the vibration motor 4, the first connecting seat 31 vibrates vertically to the maximum extent based on the second connecting seat 32.

[0075] Then, during the process of changing the vibration state, the elastic element 33 rotates, as... Figure 11 In the state shown, the two limiting plates 334 on it respectively abut against the opposite sides of the vertical direction between the first connecting seat 31 and the second connecting seat 32, thereby limiting the vertical movement direction between the first connecting seat 31 and the second connecting seat 32. In this state, after being subjected to the external action of the vibration motor 4, the first connecting seat 31 vibrates to the maximum extent in the horizontal direction based on the second connecting seat 32.

[0076] Since the two limiting plates 334 are also in contact with the connecting seat 1 31 and the connecting seat 2 32, in a fundamental sense, the vibration motor 4 will also drive the connecting seat 1 31 and the connecting seat 2 32 to perform small horizontal or vertical vibrations while driving the connecting seat 1 31 to perform maximum vertical or horizontal vibrations based on the connecting seat 2 32. In this way, the vibration motor 4 can also drive the powder tank 1 to perform slight vibrations, so that the powder inside the powder tank 1 can quickly fall to its inner bottom.

[0077] In a preferred embodiment, the connecting rod 341 is externally connected to a drive component that rotates intermittently and periodically, such as a cam divider. During the vibration of the vibration motor 4, the elastic element 33 is driven to rotate intermittently and periodically, which indirectly changes the vibration state between the connecting seat 32 and the elastic element 33. During the feeding process, the lateral vibration and vertical vibration are combined, which ensures that the powder is evenly distributed while also enabling the powder to have a high feeding speed.

[0078] The foregoing has shown and described the basic principles, main features, and advantages of the present invention. Those skilled in the art should understand that the present invention is not limited to the above embodiments. The embodiments and descriptions in the specification are merely illustrative of the principles of the invention. Various changes and modifications can be made to the invention without departing from its spirit and scope, and all such changes and modifications fall within the scope of the claimed invention.
