Description

Technical Field

[0001] This utility model relates to the field of additive device technology, specifically an automatic additive device for concrete crack-resistant agent. Background Technology

[0002] Concrete crack-resistant agent is an additive used to improve the performance of concrete, primarily to enhance its crack resistance. Cracks are a common problem in concrete structures, caused by factors such as drying shrinkage, temperature changes, and load stress. The appearance of cracks not only affects the concrete's appearance but can also lead to a decrease in the structure's durability and load-bearing capacity. Crack-resistant agents are organic polymer emulsion mixtures that fully utilize the physical and chemical changes during the curing process of cement mortar and concrete. These chemically synthesized powders prevent and resist cracking from both physical and chemical perspectives, significantly improving the strength of cement mortar and concrete. Concrete crack-resistant agents are widely used in various concrete structures requiring high strength and durability. During concrete processing, they are added to the concrete using an additive device.

[0003] Based on the search, Chinese patent application number 202021420819.0 relates to an automatic timed and quantitative addition device for concrete additives, including a mixer. A control box is connected to one side of the front surface of the mixer. The addition mechanism includes a connecting frame, a material bucket, a timer, a control valve, a discharge pipe, and a weighing sensor. During the process of adding additives, the operator can slide the sliders connected to both ends of the folding belt into the slide rails on the connecting frame and the material bucket, respectively, so that the folding belt unfolds on the slide rails. This isolates the internal components of the weighing sensor from the interference of dust and moisture in the external environment, ensuring that the accuracy of the weighing sensor's detection data is not affected.

[0004] The device described in the above patent has the following shortcomings when in use: When using a traditional concrete crack-resistant agent adding device, because the crack-resistant agent itself is an emulsion and relatively viscous, the crack-resistant agent tends to adhere to the inner wall of the equipment when it is added to the concrete crack-resistant agent. This will affect the feeding efficiency of the crack-resistant agent of the traditional device and reduce the working efficiency of the device.

[0005] To address the aforementioned problems, an automatic concrete crack-resistant agent addition device is proposed. Utility Model Content

[0006] The purpose of this invention is to provide an automatic concrete crack-resistant agent addition device. By using this device, the problem of traditional concrete crack-resistant agent addition devices in the background art being prone to adhering to the inner wall of the equipment when adding the crack-resistant agent, which is an emulsion and relatively viscous, is solved. This affects the feeding efficiency of the crack-resistant agent and reduces the working efficiency of the device.

[0007] To achieve the above objectives, this utility model provides the following technical solution: an automatic concrete crack-resistant agent adding device, comprising a storage cylinder, a striking component at the top of the storage cylinder, a feeding hopper at the top of the storage cylinder, a discharge pipe at the bottom of the storage cylinder, and two sets of support legs fixedly connected to the bottom surface of the storage cylinder; a control mechanism is provided inside the storage cylinder, the control mechanism including a fixed plate fixedly connected to the inner cavity of the storage cylinder, the outer wall of the fixed plate being tightly attached to the inner wall of the storage cylinder, and the storage cylinder containing... The component is also rotatably connected to a rotating disk, which is matched with the fixed disk. The top surface of the rotating disk and the bottom surface of the fixed disk are on the same horizontal plane. The striking assembly includes a support plate fixedly connected to the top of the storage cylinder. A first motor is fixedly connected to one side of the support plate, and a drive disk is rotatably connected to the other side of the support plate. A rubber striking block is provided at the upper end of the storage cylinder, and two sets of rubber striking blocks are provided. A connecting rod component is provided on one side of the drive disk, and one end of the connecting rod component is rotatably connected to one side of the drive disk through a first rotating shaft.

[0008] Preferably, a sealing box is fixedly connected inside the storage cylinder, and a drive motor is installed inside the sealing box.

[0009] Preferably, the rotating disk is fixedly connected to the output end of the drive motor.

[0010] Preferably, a first slot is provided on one side of the fixed disk, and a second slot is provided on one side of the rotating disk, the second slot matching the first slot.

[0011] Preferably, a limiting block is fixedly connected to one side of the support plate, and two sets of limiting blocks are provided, with a reciprocating frame plate slidably connected to one side of each set of limiting blocks.

[0012] Preferably, one end of the connecting rod component is rotatably connected to one side of the reciprocating frame plate via a second rotating shaft, and a connecting plate is fixedly connected to one side of the reciprocating frame plate, and two sets of the connecting plate are provided.

[0013] Preferably, the two sets of connecting plates are fixedly connected to the two sets of rubber striking blocks respectively.

[0014] Compared with the prior art, the beneficial effects of this utility model are as follows:

[0015] 1. Concrete additives are added during the concrete mixing process. This application uses an additive device to add crack-resistant agent to the concrete storage mixing tank. The storage cylinder can be fixedly installed above the concrete storage tank via support legs, with the discharge pipe aligned with the opening of the concrete storage tank. Crack-resistant agent is pre-added to the storage cylinder through the feed hopper. When more crack-resistant agent is needed, the valve at the discharge pipe is opened, and the crack-resistant agent in the storage cylinder flows into the bottom chamber of the storage cylinder through the first and second empty slots. The crack-resistant agent is discharged through the discharge pipe. When the operator needs to control the discharge rate of the crack-resistant agent from the storage cylinder, the drive motor can be turned on. The drive motor drives the rotating disc to rotate in the storage cylinder. The rotating disc rotates while closely adhering to the bottom surface of the fixed disc. Adjusting the rotation of the rotating disc will change the... The position of the second cavity changes with the relative position between the first and second cavities. The larger the overlapping area between the first and second cavities, the larger the discharge opening area, and thus the greater the discharge rate of the crack-resistant agent. Conversely, the smaller the overlapping area, the smaller the discharge opening area, and thus the smaller the discharge rate of the crack-resistant agent. When the first and second cavities are completely overlapping, the discharge rate of the crack-resistant agent is at its maximum. When the first and second cavities are completely far apart, the discharge opening is completely closed, the crack-resistant agent remains inside the storage cylinder, and the discharge pipe does not discharge. This design allows for easy control of the discharge rate of the crack-resistant agent through a control mechanism, preventing the discharge rate from being too fast or too slow, and ensuring that differences in human operation do not affect the strength of the concrete, thereby improving the practicality of the device.

[0016] 2. Traditional concrete crack-resistant agent adding devices often suffer from problems. Because the crack-resistant agent is an emulsion and quite viscous, it tends to adhere to the inner wall of the device during addition, affecting the feeding efficiency. Therefore, this application includes a striking component at the top of the storage cylinder. When using the storage cylinder to add material, the operator can activate the first motor. The first motor drives the drive disc to rotate, which in turn rotates one end of the connecting rod assembly. Since the reciprocating frame plate and the limiting block are in a sliding limiting fit, the end of the connecting rod assembly near the reciprocating frame plate will move the reciprocating frame plate, causing it to move along the limiting block. The reciprocating motion causes the reciprocating frame plate to drive the rubber striking blocks to reciprocate up and down. This results in two sets of rubber striking blocks reciprocatingly striking the top surface of the storage cylinder. The striking motion causes the storage cylinder to vibrate, which in turn causes vibration in the storage cylinder, the material inside the storage cylinder, and the feed pipe. This operation prevents the crack-resistant agent from adhering to the inner wall of the storage cylinder, allowing the crack-resistant agent to flow normally from the feed pipe and preventing blockage. This design, through the striking mechanism, allows the device to reciprocate, causing the crack-resistant agent adhering to the inner wall of the device to fall off due to the vibration, preventing any impact on the crack-resistant agent feeding efficiency and improving the practicality of the device.

The two sets of connecting plates 27 are fixedly connected to two sets of rubber striking blocks 28 respectively.

[0031] In summary: Concrete additives are incorporated during concrete mixing. This application uses an additive device to add crack-resistant agent to the concrete storage mixing tank. The storage cylinder 1 can be fixedly installed above the concrete storage tank via support legs 11, with the discharge pipe 13 aligned with the opening of the concrete storage tank. Crack-resistant agent is pre-added to the storage cylinder 1 through the feed hopper 12. When additional crack-resistant agent is needed, the valve of the discharge pipe 13 is opened, and the crack-resistant agent in the storage cylinder 1 flows into the bottom chamber of the storage cylinder 1 through the first empty trough 17 and the second empty trough 18. The crack-resistant agent is discharged through the discharge pipe 13. When the operator needs to control the discharge rate of the crack-resistant agent from the storage cylinder 1, the drive motor 19 can be turned on. The drive motor 19 drives the rotating disk 15 to rotate in the storage cylinder 1. The rotating disk 15 rotates while closely adhering to the bottom surface of the fixed disk 16. The rotation of the rotating disk 15 can be adjusted. This will change the position of the second empty slot 18, and the relative position between the first empty slot 17 and the second empty slot 18 will change. The larger the overlapping area of ​​the first empty slot 17 and the second empty slot 18, the larger the discharge opening area, and thus the greater the discharge rate of the crack-resistant agent. The smaller the overlapping area of ​​the first empty slot 17 and the second empty slot 18, the smaller the discharge opening area, and thus the smaller the discharge rate of the crack-resistant agent. When the first empty slot 17 and the second empty slot 18 are completely overlapping, the discharge rate of the crack-resistant agent is the maximum. When the first empty slot 17 and the second empty slot 18 are completely far apart, the discharge opening is completely closed, the crack-resistant agent remains inside the storage cylinder 1 and the discharge pipe 13 does not discharge. This setting makes it easy to control the discharge rate of the crack-resistant agent through the control mechanism, avoiding the crack-resistant agent discharge rate being too fast or too slow, and will not affect the strength of the concrete due to differences in human operation, thus improving the practicality of the device.

[0032] Traditional concrete crack-resistant agent adding devices often suffer from problems. Because the crack-resistant agent is an emulsion and quite viscous, it tends to adhere to the inner wall of the device during addition, affecting the feeding efficiency. Therefore, this application includes a striking component 2 at the top of the storage cylinder 1. When using the storage cylinder 1 to add material, the operator can activate the first motor 22. The first motor 22 drives the drive disc 23 to rotate, which in turn rotates one end of the connecting rod component 24. Since the reciprocating frame plate 26 and the limiting block 25 are in a sliding limiting fit, the end of the connecting rod component 24 near the reciprocating frame plate 26 will move the reciprocating frame plate 26, causing it to move along the limiting block. 25 makes up-and-down reciprocating motion, which in turn drives the reciprocating frame plate 26 to make up-and-down reciprocating motion together with the rubber striking blocks 28. In this way, the two sets of rubber striking blocks 28 will make reciprocating striking motion on the top surface of the storage cylinder 1. The striking motion will cause the storage cylinder 1 to vibrate, and thus the storage cylinder 1, the material inside the storage cylinder 1, and the feed pipe 13 will all be in a state of vibration. This operation can prevent the crack-resistant agent from adhering to the inner wall of the storage cylinder 1, so that the crack-resistant agent can be discharged normally from the feed pipe 13, thereby preventing the feed pipe 13 from being blocked. This setting allows the device to perform reciprocating striking work through the striking mechanism. The crack-resistant agent adhering to the inner wall of the device will fall off due to the striking vibration, preventing it from affecting the efficiency of crack-resistant agent feeding and improving the practicality of the device.

[0033] It should be noted that the aforementioned electrical components are equipped with power supplies, and their control methods are existing technologies. To avoid redundancy, they will be described here uniformly. Furthermore, this application is primarily for the protection of mechanical equipment, so the control methods and circuit connections will not be explained in detail herein. In this document, relational terms such as "first" and "second" are used merely to distinguish one entity or operation from another entity or operation, and do not necessarily require or imply any such actual relationship or order between these entities or operations.
