Technical Field
[0001] This utility model relates to the technical field of mixing devices for road and bridge construction, specifically a high-efficiency mixing device for road and bridge construction. Background Technology
[0002] In road and bridge construction, mixing equipment plays a crucial role, directly affecting the quality of construction materials and the construction progress. However, existing road and bridge construction mixing equipment has some shortcomings. On the one hand, traditional mixing equipment has low mixing efficiency, making it difficult to fully mix various raw materials evenly in a short time. During the mixing process, raw materials tend to accumulate on the walls of the mixing tank, resulting in some raw materials not being fully mixed, thus affecting the final mixing quality. On the other hand, existing mixing equipment is not efficient enough in the material discharge stage, with a slow discharge speed and a tendency to blockages during the discharge process. This not only increases construction time but may also affect the continuity of construction.
[0003] When using existing road and bridge construction mixing equipment,
[0004] (1) The stirring efficiency is low, the raw materials tend to accumulate on the barrel wall, and cannot be fully mixed, which affects the stirring quality;
[0005] (2) The material discharge speed is slow, which can easily cause blockages, reduce construction efficiency, and affect the continuity of construction.
[0006] To address the aforementioned problems, this utility model provides a highly efficient mixing device for road and bridge construction. Utility Model Content
[0007] The purpose of this invention is to provide a high-efficiency mixing device for road and bridge construction. This invention improves mixing efficiency and quality by using an automatic scraping mixing component to avoid raw material accumulation, and achieves rapid material discharge by using a rapid material discharge component to prevent blockage, thereby solving the problems in the background art.
[0008] To achieve the above objectives, this utility model provides the following technical solution: a high-efficiency mixing device for road and bridge construction, comprising a fixed base, a rapid material discharge component fixedly connected to the top of the fixed base, an automatic wall scraping mixing component fixedly connected to the top of the rapid material discharge component, the automatic wall scraping mixing component comprising a mixing drum fixedly connected to the top of the rapid material discharge component, a fixed frame fixedly connected to the top of the mixing drum, a motor box fixedly connected inside the fixed frame, a servo motor fixedly connected inside the motor box, a transmission rod fixedly connected to the output end of the servo motor, and a discharge pipe fixedly connected to one side of the bottom wall of the mixing drum.
[0009] Furthermore, a rotating roller is fixedly connected to the bottom end of the transmission rod, and a rotating disk is fixedly connected to the bottom end of the rotating roller, so that the servo motor drives the rotating roller and the rotating disk to rotate through the transmission rod, thereby providing power for stirring and scraping operations.
[0010] Furthermore, a bearing is fixedly connected to the bottom end of the rotating disk, and the bottom end of the bearing is fixedly connected to the middle of the inner bottom wall of the mixing tank. A support ring is fixedly connected to the bottom end of the rotating disk, and the bottom end of the support ring is fixedly connected to the inner bottom wall of the mixing tank. This achieves the effect of the bearing reducing friction when the rotating disk rotates, making the rotation smoother, and the support ring providing stable support for the rotating disk, ensuring the stability of the rotating disk when rotating at high speed.
[0011] Furthermore, four fixed plates arranged in a ring are fixedly connected to the surface of the rotating disk, and a scraper plate is fixedly connected to one side of the top of the fixed plate. A stirring roller is fixedly connected to the surface of the rotating roller. This achieves the effect of the rotating disk driving the fixed plates and scraper plate to rotate, the scraper plate scraping off the raw materials accumulated on the wall of the mixing tank so that they participate in the mixing, and the stirring roller fully mixing the raw materials, thereby improving the mixing efficiency and quality.
[0012] Furthermore, the rapid feeding assembly includes a support frame fixedly connected to the top of the fixed base. A U-shaped frame is slidably connected to the inner wall of the support frame. A discharge hole adapted to the discharge pipe is opened on one side of the top of the U-shaped frame. This allows the discharge hole to be aligned or offset from the discharge pipe by moving the U-shaped frame, thereby controlling the start and stop of feeding and achieving the function of rapid feeding.
[0013] Furthermore, a sliding plate is fixedly connected to the inner wall of the U-shaped frame, and a control handle is fixedly connected to the top of the U-shaped frame. This achieves the purpose of the sliding plate making the U-shaped frame slide more smoothly within the support frame, and the control handle facilitating the operator to move the U-shaped frame and control the material feeding process.
[0014] Furthermore, load-bearing columns are fixedly connected to the four corners of the bottom of the fixed base, and anti-slip plates are fixedly connected to the bottom of the load-bearing columns. This achieves the effect of the load-bearing columns supporting the weight of the entire device, and the anti-slip plates increasing the friction between the device and the ground, preventing the device from sliding during operation, and ensuring the stability of the device.

[0025] The technical solutions of the present utility model will be clearly and completely described below with reference to the accompanying drawings of the embodiments. Obviously, the described embodiments are only some embodiments of the present utility model, and not all embodiments. Based on the embodiments of the present utility model, all other embodiments obtained by those of ordinary skill in the art without creative effort are within the protection scope of the present utility model.
[0026] To solve the problem of how to effectively position and adjust the technology, such as Figures 1-5 As shown, the following preferred technical solutions are provided:
[0027] A high-efficiency mixing device for road and bridge construction includes a fixed base 1. A rapid material discharge assembly 2 is fixedly connected to the top of the fixed base 1. With the rapid material discharge assembly 2, during operation, the operator moves the U-shaped frame 202 by controlling the lever 204 to align the discharge hole with the discharge pipe 313, achieving rapid material discharge and avoiding blockage, thus improving construction efficiency. An automatic wall-scraping mixing assembly 3 is fixedly connected to the top of the rapid material discharge assembly 2. With the automatic wall-scraping mixing assembly 3, during operation, a servo motor 304 drives the rotating roller 306 and the rotating disk 3. 07 rotates, the stirring roller 312 stirs the raw materials, and at the same time the scraper plate 311 scrapes the raw materials on the barrel wall, so that the raw materials are fully mixed, improving the stirring efficiency and quality. The automatic scraper stirring component 3 includes a stirring barrel 301 fixedly connected to the top of the quick discharge component 2. A fixing frame 302 is fixedly connected to the top of the stirring barrel 301. A motor box 303 is fixedly connected inside the fixing frame 302. A servo motor 304 is fixedly connected inside the motor box 303. A transmission rod 305 is fixedly connected to the output end of the servo motor 304. A discharge pipe 313 is fixedly connected to one side of the bottom wall of the stirring barrel 301.
[0028] Specifically, when operating the device, the operator should first place the device on a stable ground to ensure that the anti-slip plate 5 at the bottom of the load-bearing column 4 is in full contact with the ground to ensure the stability of the device. Then, put all kinds of raw materials required for road and bridge construction into the mixing drum 301 in a certain proportion, start the servo motor 304 in the motor box 303 to start the mixing operation. After the mixing is completed, move the U-shaped frame 202 through the operation control so that the discharge hole on the U-shaped frame 202 is aligned with the discharge pipe 313 on the bottom wall of the mixing drum 301 so that the mixed material can be discharged quickly.
[0029] Furthermore, such as Figure 3 As shown, the following preferred technical solutions are provided:
[0030] A rotating roller 306 is fixedly connected to the bottom end of the transmission rod 305, and a rotating disk 307 is fixedly connected to the bottom end of the rotating roller 306. The purpose of this design is that when the servo motor 304 is started, its output power is transmitted to the rotating roller 306 through the transmission rod 305. The rotating roller 306 then drives the rotating disk 307 to rotate together. The rotating roller 306 and the rotating disk 307 serve as the connection hub for power transmission and stirring components, which can effectively transmit the power of the servo motor 304 to the subsequent stirring and wall scraping structure, providing stable rotational power for stirring operations.
[0031] Furthermore, such as Figure 4 As shown, the following preferred technical solutions are provided:
[0032] A bearing 308 is fixedly connected to the bottom end of the rotating disk 307. The bottom end of the bearing 308 is fixedly connected to the middle of the inner bottom wall of the mixing tank 301. A support ring 309 is fixedly connected to the bottom end of the rotating disk 307. The bottom end of the support ring 309 is fixedly connected to the inner bottom wall of the mixing tank 301. The purpose of this design is that the bearing 308 can reduce the frictional resistance between the rotating disk 307 and the inner bottom wall of the mixing tank 301 when the rotating disk 307 rotates, so that the rotating disk 307 can rotate more smoothly and flexibly, reduce energy loss, and improve mixing efficiency. The support ring 309 plays the role of supporting the rotating disk 307, ensuring the stability of the rotating disk 307 during the rotation process, preventing it from shaking or shifting due to uneven force, and ensuring the smooth progress of the entire mixing process.
[0033] Furthermore, such as Figure 3 As shown, the following preferred technical solutions are provided:
[0034] Four fixed plates 310 arranged in a ring are fixedly connected to the surface of the rotating disk 307. A scraper 311 is fixedly connected to one side of the top of the fixed plate 310. A stirring roller 312 is fixedly connected to the surface of the rotating roller 306. The purpose of this design is that when the rotating disk 307 rotates, it will drive the fixed plates 310 to rotate together. The scraper 311 on the fixed plate 310 can stick tightly to the inner wall of the mixing tank 301 and scrape off the raw materials adhering to the tank wall, so that these raw materials that were originally piled up on the tank wall can participate in the mixing again, avoiding the problem of uneven mixing caused by the accumulation of raw materials on the tank wall. At the same time, the stirring roller 312 on the surface of the rotating roller 306 will fully mix the raw materials in the mixing tank 301. The combination of the rotation of the stirring roller 312 and the scraping action of the scraper 311 greatly improves the efficiency and quality of mixing, so that various raw materials can be fully and evenly mixed.
[0035] Furthermore, such as Figure 2 As shown, the following preferred technical solutions are provided:
[0036] The rapid material discharge assembly 2 includes a support frame 201 fixedly connected to the top of the fixed base 1. A U-shaped frame 202 is slidably connected to the inner wall of the support frame 201. A discharge hole adapted to the discharge pipe 313 is opened on one side of the top of the U-shaped frame 202. The purpose of this design is to easily control the alignment and misalignment of the discharge hole and the discharge pipe 313 by sliding the U-shaped frame 202 on the support frame 201. When material discharge is required, the U-shaped frame 202 is slid to the position where the discharge hole and the discharge pipe 313 are aligned, and the mixed material can be quickly discharged through the discharge pipe 313 and the discharge hole. When material discharge is not required, the U-shaped frame 202 is slid to misalign the discharge hole and the discharge pipe 313, and the discharge pipe 313 is closed by the U-shaped frame 202 to prevent material leakage, thus realizing rapid and convenient control of the material discharge process.
[0037] Furthermore, such as Figure 2As shown, the following preferred technical solutions are provided:
[0038] A sliding plate 203 is fixedly connected to the inner wall of the U-shaped frame 202, and a control handle 204 is fixedly connected to the top of the U-shaped frame 202. The purpose of this design is to reduce the friction between the U-shaped frame 202 and the inner wall of the support frame 201, so that the U-shaped frame 202 slides more smoothly on the support frame 201, making it easier for the operator to move the U-shaped frame 202. The control handle 204 provides the operator with a convenient gripping and operating part. The operator can accurately move the U-shaped frame 202 by gripping the control handle 204, thereby accurately controlling the relative position of the discharge hole and the discharge pipe 313, improving the flexibility and accuracy of the material discharge operation.
[0039] Furthermore, such as Figure 1 As shown, the following preferred technical solutions are provided:
[0040] A load-bearing column 4 is fixedly connected to each of the four corners of the bottom of the fixed base 1. An anti-slip plate 5 is fixedly connected to the bottom of the load-bearing column 4. The purpose of this design is that the load-bearing column 4 supports the entire mixing device, distributes the weight of the device evenly on the ground, and ensures the stability of the device during operation. The anti-slip plate 5 increases the friction between the load-bearing column 4 and the ground, preventing the device from sliding or displacing due to vibration or external force during mixing, and ensuring that the device can operate safely and stably.
[0041] Working principle: When using this high-efficiency road and bridge construction mixing device, the operator first places the device stably, ensuring the anti-slip plate 5 is in good contact with the ground. After adding the raw materials into the mixing drum 301, the servo motor 304 is started. The servo motor 304 drives the transmission rod 305 to rotate, which in turn drives the rotating roller 306 and the rotating disk 307 to rotate. The rotating disk 307 drives the fixed plate 310 and the scraper plate 311 to rotate. The scraper plate 311 scrapes the raw materials from the inner wall of the mixing drum 301. The mixing roller 312 on 306 mixes the raw materials to ensure thorough mixing. After mixing, the operator holds the control handle 204 and pushes the U-shaped frame 202 to slide on the support frame 201, aligning the discharge hole on the U-shaped frame 202 with the discharge pipe 313. The mixed material is then quickly discharged through the discharge pipe 313 and the discharge hole. After discharge, the U-shaped frame 202 is slid to offset the discharge hole from the discharge pipe 313, and the servo motor 304 is turned off, completing one mixing and discharging operation.
