Description

Technical Field

[0001] This utility model relates to the field of building engineering technology, and in particular to an anti-clogging vibration feeding device for impermeable concrete. Background Technology

[0002] Impermeable concrete, as a key material for ensuring the quality of various waterproofing projects, plays a crucial role in modern construction engineering. Whether it's the basements of high-rise buildings in cities, providing people with safe and stable underground spaces; tunnels winding through mountains, bearing the heavy responsibility of transportation; or dams standing on rivers, shouldering important missions such as flood control and irrigation, impermeable concrete has become an indispensable choice due to its superior waterproofing performance.

[0003] However, in existing technologies, most devices rely solely on a single spiral conveying structure and lack targeted wall scraping and unblocking designs. Concrete residue adhering to the inner wall of the conveying cylinder will gradually accumulate and eventually cause blockage. Although some devices are equipped with vibration components, the vibration frequency is fixed and not linked to the conveying status, so it cannot be dynamically adjusted according to the degree of material agglomeration, and the effect of alleviating blockage at the feed inlet is limited. After blockage occurs, manual shutdown and cleaning are required, which not only interrupts the continuity of construction, but also wastes materials due to the initial setting of concrete during the cleaning process, increasing construction costs. Utility Model Content

[0004] The purpose of this invention is to solve the problems existing in the prior art by proposing an anti-clogging vibration feeding device for impermeable concrete.

[0005] To achieve the above objectives, the present invention adopts the following technical solution: a vibration feeding device for impermeable concrete, comprising a support frame, a controller installed at the front end of the support frame, a conveying cylinder arranged above the support frame, a feed hopper fixedly installed on the outer wall of the conveying cylinder, a support frame plate installed at one end of the conveying cylinder, a variable speed motor installed at the upper end of the support frame plate, an inclined feeding pipe fixedly installed on the outer wall of the conveying cylinder at the lower opening, a rotating rod rotatably installed inside the conveying cylinder, a connecting shaft installed at one end of the rotating rod, a spiral blade fixedly installed on the outer wall of the rotating rod, and three sets of long scrapers welded to the outer wall of the spiral blade.

[0006] Preferably, an angle sensor is installed on the outer wall of the connecting shaft, and a vibration motor is fixedly installed on both sides of the feed hopper.

[0007] Preferably, the other end of the connecting shaft is fixed to the output end of the variable speed motor, and the angle sensor is connected to the controller signal.

[0008] Preferably, the variable speed motor is connected to the controller via signal connection, and the vibration motor is also connected to the controller via signal connection.

[0009] Preferably, a vibration damping device is fixedly installed at the upper end of the support frame, and the lower end of the bracket in the conveying cylinder is fixed to the upper end of the buffer end of the vibration damping device.

[0010] Preferably, four sets of support columns are welded to the lower end of the feed hopper, and the lower ends of the four sets of support columns are all fixed to the upper end of the buffer end in the vibration damping device.

[0011] Compared with the prior art, the advantages and positive effects of this utility model are as follows: 1. In this utility model, the efficient anti-clogging mechanism ensures continuous material feeding. The pushing action of the spiral blades and the scraping function of the long scraper can effectively remove the concrete adhering to the inner wall of the conveying cylinder, avoiding material accumulation and blockage. The vibrating motors on both sides of the feed hopper loosen the material by vibration, preventing the feed inlet from clumping and blocking. The inclined feed pipe accelerates the discharge of materials. The triple anti-clogging design significantly reduces the probability of blockage and ensures the continuous feeding of impermeable concrete.

[0012] 2. In this utility model, intelligent control is used to adapt to complex working conditions. An angle sensor monitors the rotation speed of the rotating rod in real time, and the controller automatically adjusts the working parameters of the variable speed motor and the vibration motor according to the monitoring data. It can meet the material feeding requirements of impermeable concrete with different slump and different aggregate gradations without manual intervention, thereby improving the adaptability of the device to complex construction conditions.

[0013] 3. In this utility model, the vibration damping device at the upper end of the support frame can absorb the impact force generated by the vibration motor and the conveying mechanism, reduce the wear of the connection structure of each component due to the overall vibration of the device, and extend the service life of the equipment; at the same time, it reduces vibration noise and improves the construction environment.

[0017] Many specific details are set forth in the following description in order to provide a full understanding of the present invention. However, the present invention may also be implemented in other ways different from those described herein. Therefore, the present invention is not limited to the specific embodiments disclosed in the following specification.

[0018] Example: Figure 1 , Figure 2 , Figure 3 and Figure 4 As shown, this utility model provides an anti-clogging vibratory feeding device for impermeable concrete, including a support frame 1, a controller 2 installed at the front end of the support frame 1, a conveying cylinder 4 arranged above the support frame 1, a feeding hopper 5 fixedly installed on the outer wall of the conveying cylinder 4, a support frame plate 6 installed at one end of the conveying cylinder 4, a variable speed motor 7 installed at the upper end of the support frame plate 6, an inclined feeding pipe 8 fixedly installed on the outer wall of the conveying cylinder 4 at the lower opening, a rotating rod 10 rotatably installed inside the conveying cylinder 4, a connecting shaft 11 installed at one end of the rotating rod 10, a spiral blade 14 fixedly installed on the outer wall of the rotating rod 10, three sets of long scrapers 15 welded to the outer wall of the spiral blade 14, an angle sensor 12 installed on the outer wall of the connecting shaft 11, vibratory motors 13 fixedly installed on both sides of the feeding hopper 5, the other end of the connecting shaft 11 fixed to the output end of the variable speed motor 7, the angle sensor 12 is signal-connected to the controller 2, the variable speed motor 7 is signal-connected to the controller 2, and the vibratory motor 13 is signal-connected to the controller 2.

[0019] A vibration damping device 3 is fixedly installed on the upper end of the support frame 1. The lower end of the bracket in the conveying cylinder 4 is fixed to the upper end of the buffer end in the vibration damping device 3. Four sets of support columns 9 are welded to the lower end of the feed hopper 5. The lower ends of the four sets of support columns 9 are all fixed to the upper end of the buffer end in the vibration damping device 3.

[0020] The specific settings and functions of this embodiment are described below. The support frame 1 serves as the load-bearing foundation of the overall structure, ensuring that the device is placed stably during construction. A vibration damping device 3 is fixedly installed on the upper end of the support frame 1. The vibration damping device 3 adopts a spring-damping composite structure (or rubber buffer assembly). Its buffer end is connected to the lower end of the support of the conveying cylinder 4 and the support column 9 of the feed hopper 5, which can effectively absorb the impact force generated by vibration, reduce the wear and tear on the support structure caused by the overall vibration of the device, and reduce the noise of the construction environment.

[0021] A conveying cylinder 4 is provided above the support frame 1 of the conveying mechanism, serving as the main conveying channel for impermeable concrete. A feed hopper 5 is fixedly installed on the outer wall of the conveying cylinder 4. The feed hopper 5 is a funnel-shaped structure with a large upper opening and a small lower opening. Four sets of support columns 9 are welded to the lower end. The lower end of the support columns 9 is fixed to the buffer end of the vibration damping device 3, further enhancing the stability of the feed hopper 5. A support frame plate 6 is installed at one end of the conveying cylinder 4. A variable speed motor 7 fixed at the upper end of the support frame plate 6 serves as the power source for conveying. Its output end is connected to the rotating rod 10 inside the conveying cylinder 4 through a connecting shaft 11. The concrete conveying speed can be controlled by adjusting the rotation speed.

[0022] The anti-clogging mechanism includes a rotating rod 10 inside the conveying cylinder 4 with a helical blade 14 fixed to its outer wall. The helical blade 14 is in clearance fit with the inner wall of the conveying cylinder 4, and can push concrete along the conveying cylinder 4 by rotation to prevent material accumulation. Three sets of long scrapers 15 are also welded to the outer wall of the helical blade 14. The long scrapers 15 are in close contact with the inner wall of the conveying cylinder 4 and can scrape off concrete residue adhering to the cylinder wall when rotating synchronously with the helical blade 14, preventing blockage caused by material adhesion. An inclined discharge pipe 8 is fixedly installed at the lower opening of the conveying cylinder 4. The inclination angle is designed to be 30°-60° (optimized according to the fluidity of concrete). With the pushing force of the helical blade 14, it accelerates the discharge of material and reduces the risk of pipe blockage.

[0023] Vibration motors 13 are symmetrically fixed on both sides of the vibrating mechanism feed hopper 5. The vibration frequency of the vibration motors 13 can be adjusted by the controller 2. When working, the vibration force generated by the vibration motors 13 is transmitted to the feed hopper 5, which loosens the concrete in the hopper after vibration, avoids the blockage of the feed inlet caused by material agglomeration or changes in slump, and ensures that the material enters the conveying cylinder 4 evenly.

[0024] A controller 2 (with built-in PLC control system) is installed at the front end of the control mechanism support frame 1. An angle sensor 12 is installed on the outer wall of the connecting shaft 11. The angle sensor 12 can monitor the rotation speed and rotation angle of the rotating rod 10 in real time and transmit the signal to the controller 2. The controller 2 is connected to the variable speed motor 7 and the vibration motor 13 respectively. According to the speed change fed back by the angle sensor 12 (such as a sudden drop in speed indicating possible blockage), the controller can automatically adjust the output power of the variable speed motor 7 (increasing the speed to enhance the pushing force) or the vibration frequency of the vibration motor 13 (enhancing the vibration of the feed hopper 5 to prevent blockage) to achieve intelligent anti-blockage control.

[0025] The usage and working principle of this device: Loose feeding: During construction, the impermeable concrete enters through the feeding hopper 5. The vibrating motors 13 on both sides of the feeding hopper 5 are started. The vibration force loosens the material in the hopper to avoid clumping and blockage, and ensures that it enters the conveying cylinder 4 evenly. Conveying anti-blockage: The controller 2 drives the variable speed motor 7 to rotate, which drives the rotating rod 10 and the spiral blade 14 inside the conveying cylinder 4 to rotate through the connecting shaft 11. The spiral blade 14 pushes the material to move towards the discharge end; the synchronously rotating long scraper 15 scrapes off the material adhering to the cylinder wall to prevent accumulation and blockage. Intelligent control: The angle sensor 12 on the connecting shaft 11 monitors the rotation speed of the rotating rod 10 in real time. If the rotation speed drops suddenly, the controller 2 automatically adjusts the speed of the variable speed motor 7 or the frequency of the vibration motor 13. Stable material discharge: The conveyed material is discharged rapidly through the inclined discharge pipe 8 to complete the discharge; the vibration damping device 3 on the support frame 1 absorbs vibration and shock, ensuring stable overall operation.

[0026] The above are merely preferred embodiments of this utility model and are not intended to limit the utility model in any other way. Any person skilled in the art may make changes or modifications to the above-disclosed technical content to create equivalent embodiments for application in other fields. However, any simple modifications, equivalent changes, and modifications made to the above embodiments based on the technical essence of this utility model without departing from the technical solution of this utility model shall still fall within the protection scope of this utility model.
