Description

Technical Field

[0001] This invention belongs to the field of road construction machinery technology, and in particular relates to a multi-stage vibration uniform concrete placing machine. Background Technology

[0002] In road construction and building engineering, materials with a high loose paving coefficient, such as lightweight aggregates, irregularly shaped crushed stone, and asphalt mixtures, often face the problem of uneven distribution during the placement process. Due to their large internal friction angle, high viscosity, and uneven composition, these materials frequently encounter the following problems when using traditional concrete placing booms: First, the material easily clumps together, causing blockages at the discharge port; second, the material easily separates during placement, resulting in uneven thickness; third, the fixed placement position causes the material to accumulate in a designated area, forming a "pyramid" distribution, affecting subsequent compaction; and fourth, the material has strong adhesion to machine parts, affecting the smoothness of the placement process.

[0003] Existing concrete placing booms primarily rely on the uniform horizontal movement of the placing hopper during unloading to achieve even concrete distribution. However, this method is often ineffective for materials with a high loose paving coefficient. In particular, for asphalt mixtures, their temperature sensitivity, adhesion characteristics, and uneven composition prevent traditional concrete placing booms from achieving ideal distribution results, thus affecting the final road quality.

It should be noted that those skilled in the art can make several modifications to the present invention without departing from the principle of the present invention, and these improvements and modifications also fall within the protection scope of the claims of the present invention.

[0046] Example 1

[0047] As one embodiment, a multi-stage vibration uniform distribution machine is proposed, such as...

The vibrating conveying system 4 generates low-frequency large-amplitude vibration and high-frequency small-amplitude vibration; the temperature control system 5 is used to heat the hopper system 2 and maintain the temperature of the hopper system 2 to maintain the optimal working temperature of the material in the hopper system 2; the uniform distribution system 6 includes a lateral moving mechanism 61, a diffuser plate 63 and a uniform distributor 64. The lateral moving mechanism 61 is located below the multi-stage vibrating conveying system 4, and the uniform distributor 64 is connected to the lower end of the lateral moving mechanism 61 through the diffuser plate 63; the intelligent control unit 7 is used to control the hopper system 2, the anti-caking system 3, the multi-stage vibrating conveying system 4 and the uniform distribution system 6, and automatically adjusts the working parameters of each system according to the material characteristics.

[0048] like Figure 1 and Figure 2 As shown, the hopper system 2 is installed on the upper part of the frame 1, including a main hopper 21 and an auxiliary hopper 22. The inner surface of the main hopper 21 is coated with an anti-stick coating made of polytetrafluoroethylene material and nano-ceramic particles. The surface has a micro-uneven structure, which reduces the contact area between the material and the hopper wall and significantly reduces the adhesion force. The auxiliary hopper 22 is installed below the main hopper 21 and has a hydraulic control valve 23 at the bottom. The valve opening can be precisely adjusted within the range of 0-100% to control the discharge rate.

[0049] like Figure 3-5As shown, the anti-caking system 3 is installed inside the main hopper 21. The anti-caking system 3 includes a rotary dispersant 31 and a high-frequency pulse airflow device 33. The rotary dispersant 31 consists of multiple sets of staggered star rotors 32. The star rotors 32 adopt a multi-layer design, with each layer staggered. The star rotors 32 are made of high-strength wear-resistant material with an edge strength higher than HRC55, and the surface of the star rotors 32 is provided with dispersing teeth. Adjacent star rotors 32 rotate in opposite directions, and their speed is adjusted within the range of 0-300 rpm.

The vibration direction can be switched between vertical, horizontal, and combined directions to adapt to different material properties. The secondary high-frequency small-amplitude vibration unit 43 adopts a multi-point distributed electromagnetic vibrator 44 with a vibration frequency range of 20-100Hz and an amplitude range of 0.5-3mm. Each electromagnetic vibrator 44 can be independently controlled to form a traveling wave or standing wave vibration field, which promotes the uniform flow of loose materials. The low-frequency vibration is mainly responsible for breaking down the internal structure of the material, while the high-frequency vibration promotes the uniform flow of the material. The two-stage vibration works synergistically to significantly improve the flow characteristics of loose materials.

[0053] like Figure 7As shown, the temperature control system 5 includes a heating unit and a control unit. The heating unit includes an infrared heater 51 and an electric heating element 52. The infrared heater 51 is installed on the upper part of the hopper system 2 to provide non-contact rapid heating, and the electric heating element 52 is embedded in the side wall of the hopper system 2 to provide continuous and uniform heat. The control unit includes a temperature sensor array 53 and a temperature controller 54. The temperature sensor array 53 includes several temperature sensors, which are evenly distributed in the hopper system 2 and are used to monitor the temperature of the hopper system 2. The temperature controller controls the heating power of the heating unit according to the temperature data obtained by the temperature sensors. The temperature control accuracy reaches ±2℃, which is suitable for temperature-sensitive materials such as asphalt mixtures.

[0054] like Figure 8 As shown, the uniform distribution system 6 includes a lateral movement mechanism 61, a servo motor 62, a diffuser plate 63, and a uniform distributor 64. The lateral movement mechanism 61 is connected to the servo motor 62, and the lateral movement mechanism 61 is driven by the servo motor 62 to ensure that the distribution of the material is uniform within a predetermined range. The diffuser plate 63 connected to the end of the lateral movement mechanism 61 adopts a multi-level folding design, and its surface is a parabolic surface with a special curvature, which is used to uniformly diffuse the falling material in an umbrella-like shape. The surface of the diffuser plate is inlaid with hard alloy protrusions, which not only increases the material dispersion effect but also reduces material adhesion. The uniform distributor 64 consists of 10 independently controlled segmented distribution plates 65, each segmented distribution plate 65 is 20cm wide, the total width of the uniform distributor 64 is 200cm, the tilt angle adjustment range is 0-30°, the opening adjustment range is 0-100%, and the vibration transmission coefficient of the segmented distribution plate 65 surface is greater than 0.85. The segmented distribution plate 65 adopts a V-groove design to increase the guidance of the material.

[0065] Step 2: Set working parameters. Operators can input parameters such as material type, fabric thickness, and fabric width through the control panel, or select automatic mode, and the intelligent control unit 7 will automatically set the optimal parameters according to the material characteristics.

[0067] Step 4: Material loading. The transport vehicle pours materials with a high looseness coefficient into the main hopper 21.

[0068] Step 5: Anti-clumping treatment. The rotary disperser 31 starts working, and the star rotor 32 rotates at a preset speed. Combined with high-frequency pulsed airflow, it disperses materials that may clump together.

[0069] Step 6: The multi-stage vibration conveying system 4 is started. The first-stage low-frequency large-amplitude vibration unit 41 generates low-frequency large-amplitude vibration to break down the internal structure of the material; the second-stage high-frequency small-amplitude vibration unit 43 generates high-frequency small-amplitude vibration to promote uniform material flow.

[0070] Step 7: The uniform distribution system 6 is in operation. The lateral moving mechanism 61 moves along a preset trajectory under the drive of the servo motor 62.

The intelligent control unit 7 monitors the material flow status and temperature distribution parameters in real time through the sensor network 72, and automatically adjusts the working status of each system in cooperation with the actuator drive module 73 and the central processing unit 71 to ensure the quality of the fabric.

[0072] Step 9: Complete the fabric application. Once the fabric application task is completed, the equipment will automatically enter the cleaning mode to prevent residual material from solidifying inside the equipment.
