Description

Technical Field

[0001] The utility model belongs to the technical field of concrete processing, and in particular relates to a high-performance concrete auxiliary material adding device. Background Art

[0002] High-performance concrete (HPC) is a type of concrete with high compressive strength, durability, and chemical resistance. It is typically prepared using high-quality cement, smaller aggregates, premium admixtures, and well-blended materials. High-performance concrete can improve the performance of concrete by optimizing material ratios and concrete mix ratios, controlling the water-cement ratio, and using efficient curing methods. Due to its high compressive strength and durability, high-performance concrete is often used in structural projects that need to withstand large loads and have strict usage requirements, such as high-rise buildings, bridges, tunnels, etc. The prior art discloses a concrete auxiliary material addition mechanism, application number: CN201720633262.0. In order to solve the problem that the addition of auxiliary materials requires manual pouring, which causes uneven pouring and affects the subsequent mixing effect, the auxiliary materials are guided by a spiral guide shaft to prevent clogging, and the main material is freely fallen from the main material hopper into the mixing drum. The structure after adopting this solution is reasonable, the auxiliary material addition effect is good, and it is not easy to clog. However, in the above technical solution, the auxiliary material is fed at a fixed flow rate. Since the types of auxiliary materials added are different, the amount of auxiliary materials added also needs to be changed accordingly. Therefore, the fixed flow rate of auxiliary material addition cannot meet the usage requirements. Utility Model Content

[0003] (1) Technical problems to be solved

[0004] In view of the shortcomings of the existing technology, the purpose of this utility model is to provide a high-performance concrete auxiliary material adding device, which aims to solve the problem that the feed of auxiliary materials in the existing technology is at a fixed flow rate, and since the types of auxiliary materials added are different, the amount of auxiliary materials added also needs to be changed accordingly.

[0005] (2) Technical solution

[0006] In order to solve the above technical problems, the present invention provides a high-performance concrete auxiliary material adding device, comprising a main hopper, an adding hopper, a drive assembly and a feed pipe, wherein the adding hopper is arranged on the side of the main hopper, and an inclined material pipe is connected below the adding head, and a feed pipe is connected below the inclined material pipe, and the feed pipe is arranged horizontally and communicated with the main hopper; a drive assembly is arranged inside the feed pipe, and the drive assembly includes a lifting frame, and an inclined plate is fixed on the inner upper surface of the lifting frame, and the high end of the inclined plate corresponds to the inclined material pipe, and the low end faces the main hopper; a mounting block is fixed at the bottom of the lifting frame, and the mounting blocks are spaced apart in two groups, and the two groups of mounting blocks are respectively rotatably mounted on a rotating shaft, and the end of the rotating shaft away from the mounting block is fixedly connected to a fixed head, and the bottom of the fixed head is connected to a telescopic cylinder. Thanks to the arrangement of the drive assembly, the flow rate of the auxiliary materials to be added can be controlled. After the auxiliary materials of different specifications enter the adding hopper, the flow rate can be changed according to the proportional requirements, thereby meeting the production requirements of high-performance concrete.

[0007] Preferably, a mounting bracket is fixedly mounted on the outer wall of the feed pipe, the mounting bracket is an L-shaped structure, and the telescopic cylinder is mounted on the inner side of the mounting bracket.

[0008] Preferably, the telescopic end of the telescopic cylinder penetrates along the bottom of the feed pipe.

[0009] Preferably, the end of the lifting frame remote from the telescopic cylinder is movably connected to the inner wall of the feed pipe. Because the fixed head is pivotally connected to the bottom of the lifting frame, the lifting frame is forced to tilt slightly upward, thereby increasing the inclination of the inclined plate itself and improving the flow rate of the auxiliary material. When the telescopic cylinder contracts, the lifting frame is forced to tilt slightly downward, gradually inclining the inclined plate toward horizontality, thereby slowing the flow rate of the auxiliary material.

[0010] Preferably, the inclined material tube is communicated with the feed pipe, and a driving motor is fixedly mounted on the outer wall of the inclined material tube.

[0011] Preferably, a stirring shaft is connected to the output shaft of the driving motor, and the stirring shaft is rotatably embedded in the inclined material tube.

[0013] (3) Beneficial effects

[0014] Compared with the prior art, the beneficial effects of the present invention are:

[0015] Thanks to the setting of the driving component, the utility model can control the flow rate of the auxiliary materials that need to be added. After the auxiliary materials of different specifications enter the adding bucket, the flow rate can be changed according to the proportional requirements to meet the production needs of high-performance concrete. The lifting frame is driven by the telescopic cylinder at the bottom, and the telescopic cylinder extends upward. Since the fixed head and the bottom of the lifting frame are rotatably connected, the lifting frame will be forced to tilt slightly upward, and then the inclination of the inclined plate itself will increase, and the flow rate of the auxiliary material will be improved. When the telescopic cylinder contracts, the lifting frame will be forced to decrease slightly, and the inclination of the inclined plate will gradually tend to be horizontal, and then the flow rate of the auxiliary material will also slow down. The principle is simple and easy to implement, and can be widely promoted. BRIEF DESCRIPTION OF THE DRAWINGS

Obviously, the embodiments described are only part of the embodiments of the present invention, not all of the embodiments. Based on the embodiments of the present invention, all other embodiments obtained by ordinary technicians in this field without making creative efforts are within the scope of protection of the present invention.

[0023] This specific embodiment is a high performance concrete auxiliary material adding device, and its structural diagram is as follows Figure 1As shown, it includes a main hopper 1, an adding hopper 2, a drive assembly 5 and a feed pipe 4.

The feed pipe 4 is horizontally arranged and connected to the main hopper 1.

[0024] Reference Figure 2 、 Figure 3 The inside of the feeding pipe 4 is provided with a driving assembly 5, which includes a lifting frame 9. An inclined plate 8 is fixed to the inner upper surface of the lifting frame 9. The higher end of the inclined plate 8 corresponds to the inclined feeding pipe 3, and the lower end faces the main hopper 1; a mounting block 13 is fixed to the bottom of the lifting frame 9. There are two groups of mounting blocks 13 spaced apart. A rotating shaft 10 is rotatably mounted on the two groups of mounting blocks 13. The end of the rotating shaft 10 away from the mounting block 13 is fixedly connected to a fixed head 12, and the bottom of the fixed head 12 is connected to a telescopic cylinder 11. A mounting bracket 7 is fixedly mounted on the outer wall of the feeding pipe 4. The mounting bracket 7 is an L-shaped structure, and the telescopic cylinder 11 is installed on the inner side of the mounting bracket 7. The telescopic end of the telescopic cylinder 11 penetrates along the bottom of the feeding pipe 4. The end of the lifting frame 9 away from the telescopic cylinder 11 is movably connected to the inner wall of the feeding pipe 4.

[0025] Reference Figure 4 The inclined feed tube 3 is connected to the feed tube 4, and a drive motor 6 is fixedly mounted on the outer wall of the inclined feed tube 3. The output shaft of the drive motor 6 is connected to a stirring shaft 15, which is rotatably embedded in the inclined feed tube 3. The outer wall of the stirring shaft 15 is surrounded by multiple sets of crushing plates 14, which are fixedly connected to the stirring shaft 15.

[0026] Working principle: When in use, during the production of high-performance concrete, the main material is added from the main hopper 1, and the required auxiliary materials are added from the adding hopper 2. The number of adding hoppers 2 can be set to multiple. When adding auxiliary materials, the auxiliary materials are first added to the adding hopper 2, and then slide along the inclined material pipe 3 toward the inner side of the feed pipe 4. After entering the feed pipe 4, the auxiliary materials are received by the lifting frame 9. The upper surface of the lifting frame 9 has an inclined plate 8, and then the auxiliary materials slide along the inclined plate 8 toward the inside of the main hopper 1. The inclined plate 8 can accelerate the flow rate of the auxiliary materials to avoid blockage of the auxiliary materials. When the auxiliary materials need to be fed into the hopper 2, the auxiliary materials are fed into the hopper 2. When speeding up the addition, the telescopic cylinder 11 can be started, and the telescopic cylinder 11 extends upward. Since the fixed head 12 is rotatably connected to the bottom of the lifting frame 9, the lifting frame 9 will be forced to tilt slightly upward, and then the inclination of the inclined plate 8 itself will increase, and the flow rate of the auxiliary material will be improved. When the telescopic cylinder 11 contracts, the lifting frame 9 will be forced to drop slightly, and the inclination of the inclined plate 8 will gradually tend to be horizontal, and then the flow rate of the auxiliary material will also slow down. It can be selected according to production needs and is easy to use. The telescopic cylinder 11 is movably arranged in the mounting frame 7, and when it is extended and retracted, it can move in an arc shape.
