Description

Technical Field

[0001] This application relates to the technical field of mixing equipment, and in particular to a road concrete mixing device. Background Technology

[0002] During urban road construction, a large amount of concrete is usually required for on-site operations.

[0003] Due to limitations imposed by construction conditions, concrete mixer trucks and other equipment cannot be brought into the site. In such cases, on-site workers must use mixers to process the concrete. Specifically, workers place the raw materials into a mixing drum, which is then mixed by the mixer. After processing, the concrete is removed from the drum, the drum is cleaned, and raw materials are added again for the next batch.

[0004] Regarding the aforementioned technologies, the concrete mixing and processing steps, such as feeding and unloading, require a considerable amount of time, resulting in relatively limited overall concrete processing efficiency. Therefore, there is room for improvement. Utility Model Content

[0005] To improve the efficiency of concrete processing at construction sites, this application provides a highway concrete mixing device.

[0006] This application provides a highway concrete mixing device, which adopts the following technical solution: A highway concrete mixing device includes a frame on which a mixing assembly and a loading assembly are mounted. The stirring assembly is supported on the top of the frame. The stirring assembly includes a stirring base, a stirrer, and a sliding drive component. The stirrer is mounted on the stirring base, and the sliding drive component is connected to the stirring base to drive the stirring base to slide in the horizontal direction. The loading assembly is located below the stirring assembly. The loading assembly includes a support and a lifting drive. Several material buckets are placed on the support, and the material buckets are distributed along the sliding direction of the stirring seat. The lifting drive is connected to the support and is used to drive the support to move vertically.

[0007] By adopting the above technical solution, after the mixer mixes the raw materials in the bucket to form concrete, the lifting drive drives the support to move the bucket downwards, so that the mixer is detached from the bucket, making it easy to remove the bucket for unloading. At the same time, the sliding drive drives the mixing support to move the mixer to the top of the remaining bucket on the frame, and the lifting drive drives the support to move the remaining bucket upwards until the mixer is located inside the bucket, so that the mixer can continue to mix the raw materials in the remaining buckets. This helps to improve the continuity of concrete mixing and processing. Compared with traditional concrete mixing and processing methods, it effectively saves the time for unloading and loading, and improves the overall mixing efficiency of concrete processing.

[0008] Preferably, the top of the frame is supported by several guide rods, and the bottom of the stirring seat is connected to several sliders, with the sliders slidably connected to the guide rods respectively.

[0009] By adopting the above technical solution, the slider and guide rod are used to guide and limit the stirring seat, which helps the sliding drive component to drive the stirring seat to slide back and forth in the horizontal direction more smoothly and steadily.

[0010] Preferably, the stirrer includes a drive unit and a stirring rod, the drive unit being drivenly connected to the stirring rod for driving the stirring rod to rotate; The stirring seat is provided with a connecting pipe corresponding to the driving part. The bottom end of the driving part passes through the connecting pipe. A fastening bolt is threaded through the outer circumference of the connecting pipe and is tightly abutted against the driving part.

[0011] By adopting the above technical solution, the agitator can be stably installed and fixed on the agitator base, and the agitator can be removed from the agitator base, which facilitates disassembly and maintenance of the agitator in case of subsequent damage.

[0012] Preferably, the support is connected to a plurality of limiting rings corresponding to the material bucket, and the bottom end of the material bucket is embedded in the corresponding limiting ring.

[0013] By adopting the above technical solution, the limiting ring is used to limit the position of the material bucket, so that the material bucket can be placed stably on the support, preventing the material bucket from shaking or shifting during the mixing process, and facilitating the agitator to stably stir the raw materials in the material bucket.

[0014] Preferably, the lifting drive component includes a scissor lift, which is installed at the bottom of the frame, and the support is connected to the bottom of the scissor lift.

[0015] By adopting the above technical solution, the scissor lift is used to drive the support to move the bucket up and down. On the one hand, it is convenient for the agitator to stir the raw materials at different heights inside the bucket. On the other hand, it is convenient for the agitator to contact and separate from the raw materials inside the bucket.

[0016] Preferably, the bottom of the frame is vertically connected to several legs, and the bottom end of each leg is vertically connected to a support plate.

[0017] By adopting the above technical solution, the bottom of the frame is raised off the ground by using outriggers, which reduces the possibility of rainwater soaking the bottom of the frame and causing damage to the internal scissor lift and other structures. By connecting support plates to the bottom of the outriggers, the contact area between the outriggers and the ground is increased, making it easier to place the frame stably as a whole.

[0018] Preferably, a limiting bolt is threaded through the outer circumference of the limiting ring, and the limiting bolt abuts against the outer circumference of the corresponding material barrel.

[0019] By adopting the above technical solution, after the material bucket is placed inside the limiting ring, the limiting bolt on the outer circumference of the limiting ring is turned so that the limiting bolt is pressed against the outer circumference of the material bucket. The limiting bolt is used to further limit the material bucket, so as to better restrict the material bucket from shaking and shifting due to the subsequent stirring of the agitator.

[0020] Preferably, the inner circumference of the limiting ring is padded with a flexible buffer pad.

[0021] By adopting the above technical solution, a flexible buffer pad is used to buffer and protect the material bucket, limiting the rigid collision between the material bucket and the limiting ring that could cause damage. At the same time, the flexible buffer pad can absorb the vibration generated during the mixing process, reducing the noise generated when the material bucket is being mixed.

[0022] In summary, this application includes at least one of the following beneficial technical effects: 1. The mixer is moved above different material buckets by the sliding drive component, and the lifting drive component is used to move multiple material buckets up and down to achieve the mixer to alternately mix the raw materials in several material buckets for concrete processing. This effectively saves the unloading and loading time of concrete mixing and processing and improves the efficiency of concrete mixing and processing.

[0023] 2. By passing the drive unit of the agitator through the connecting pipe on the mixing base, and by using the fastening bolts on the outer periphery of the connecting pipe to limit and fix the drive unit, the agitator is securely installed on the mixing base, while facilitating the subsequent disassembly and replacement of the agitator.

[0024] 3. By setting a limiting ring on the support, when placing the material bucket, the bottom end of the material bucket can be embedded into the limiting ring, and the limiting ring is used to limit the material bucket to prevent the material bucket from shifting due to the agitation of the mixer.

[0030] The following is in conjunction with the appendix Figure 1-4 This application will be described in further detail.

[0031] Example 1 This application discloses a highway concrete mixing device, referring to... Figure 1 and Figure 2 The system includes a frame 1, from top to bottom, with a mixing assembly 2 and a loading assembly 3. The mixing assembly 2 includes a mixing base 21, a mixer 22, and a sliding drive component. The mixer 22 is vertically mounted on the mixing base 21 and is used to mix concrete raw materials. The sliding drive component is driven to the mixer 22 and is used to drive the mixer to slide horizontally. The loading assembly 3 includes a support 30 and a lifting drive component. Several material buckets 31 are placed on the support 30 and are evenly distributed along the sliding direction of the mixing base 21. The lifting drive component is driven to the support 30 and is used to drive the support 30 to rise and fall vertically.

[0032] When mixing and producing concrete, the mixer 22 can mix the raw materials in the bucket 31. After the concrete is mixed and produced, the lifting drive is used to drive the support 30 to move the bucket 31 down, so that the mixer 22 can be removed from the bucket 31 for easy removal and unloading. At the same time, the sliding drive is used to drive the mixing support 30 to move the mixer 22 to above the remaining bucket 31 on the frame 1. Then, the lifting drive is used to drive the support 30 to move the remaining bucket 31 up, so that the mixer 22 can enter the bucket 31 for continued mixing and processing.

[0033] Reference Figure 1 and Figure 2The sliding drive component includes a cylinder 20, which is mounted and fixed at one end of the top of the frame 1; the stirring support 30 is welded with a connecting plate 210 corresponding to the cylinder 20, and the end of the piston rod of the cylinder 20 is connected to the connecting plate 210 to realize the driving connection between the sliding drive component and the stirring base 21.

[0034] Two guide rods 212 are mounted on the top of the frame 1 corresponding to the stirring base 21, and the two guide rods 212 are arranged in parallel. Two sliders 211 are connected to two sliding rods at the bottom of the stirring base 21, and the two sliders 211 are slidably connected to the two sliding rods respectively. The sliders 211 and the guide rods 212 are used to guide and limit the stirring base 21, which helps the cylinder 20 to drive the stirring base 21 to move the agitator 22 back and forth more smoothly.

[0035] Reference Figure 2 and Figure 3 The agitator 22 includes a drive unit 221 and an agitator rod 222. Several agitator blades are fixed to the outer periphery of the agitator rod by bolts. The drive unit 221 adopts an existing geared motor. The top end of the agitator rod 222 is connected to the output end of the drive unit 221 through a coupling. The drive unit 221 drives the agitator rod 222 to rotate the agitator blades, thereby agitating the raw materials in the material tank 31.

[0036] A connecting pipe 23 is fixedly installed on the mixing base 21 corresponding to the drive part 221 of the stirrer 22. The bottom end of the drive part 221 passes through the connecting pipe 23, and a fastening bolt 231 is threaded through the outer circumference of the connecting pipe 23. The end of the fastening bolt 231 is tightened against the outer circumference of the bottom end of the drive part 221 to restrict the sliding of the drive part 221, so that the mixing base 21 can better drive the stirrer 22 to move. At the same time, it realizes the detachable connection between the stirrer 22 and the mixing base 21, so that the stirrer 22 can be easily removed from the mixing base 21 when it is replaced or cleaned. The drive part 221 is connected to grips on both sides to facilitate the movement of the drive part 221.

[0037] The lifting drive includes a scissor lift 32, the bottom of which is fixed to the bottom of the frame 1 by bolts. The bottom of the support 30 is bolted to the top of the scissor lift 32. In daily use, the scissor lift 32 drives the support 30 and the material bucket 31 on the support 30 to move vertically up and down.

[0038] Reference Figure 1 and Figure 3 The support 30 is welded and fixed with several limiting rings 301 corresponding to several material barrels 31. The bottom of each material barrel 31 is embedded in the corresponding limiting ring 301. The limiting rings 301 limit the material barrel 31 to prevent displacement of the material barrel 31 when the support 30 moves the material barrel 31 up and down. This is conducive to the stable contact between the raw material in the material barrel 31 and the agitator 22, and makes it easier for the agitator 22 to better agitate the raw material inside the material barrel 31.

[0039] Support legs 10 are welded to the four corners of the bottom of the frame 1. The support legs 10 are set vertically downwards. The support legs 10 work together to lift the frame 1 off the ground to prevent rainwater from soaking the bottom of the frame 1 and the scissor lift 32. Support plates 101 are welded vertically to the bottom of the support legs 10. The support plates 101 increase the contact area between the support legs 10 and the ground, so that the frame 1 can be placed stably on the ground.

[0040] The implementation principle of Example 1 is as follows: Before concrete production, raw materials are added to various buckets 31 on the support 30. After the raw materials in one bucket 31 are mixed and processed by the mixer 22, the support 30 is driven by the scissor lift 32 to move the bucket 31 downwards until it detaches from the mixer 22. Simultaneously, the bucket containing the completed concrete is removed for unloading. At the same time, the cylinder 20 drives the mixing seat 21 to move the mixer 22 above the remaining buckets 31 on the support 30. The scissor lift 32 then drives the support 30 to move the buckets 31 upwards, so that the raw materials inside the buckets 31 come into contact with the mixing rod 222 of the mixer 22, and the mixer 22 mixes the raw materials in the buckets 31. This effectively saves time on loading and unloading, improving the continuity of concrete production.

[0041] Example 2 The difference between Example 2 and Example 1 is that: (Refer to...) Figure 3 and Figure 4 The limiting ring 301 is threaded with a limiting bolt 303. The end of the limiting bolt 303 is pressed against the outer periphery of the material barrel 31 located inside the limiting ring 301. The limiting bolt 303 is used to further limit the material barrel 31 to restrict the material barrel 31 from shaking or shifting during the stirring process.

[0042] The inner circumference of the limiting ring 301 is lined with a flexible buffer pad 302, which is made of materials such as rubber or silicone. The flexible buffer pad 302 is used to buffer and protect the material bucket 31, preventing the material bucket 31 from being damaged by rigid collision with the limiting ring 301. At the same time, the flexible buffer pad 302 can absorb the vibration generated during the stirring process and reduce the noise generated by the material bucket 31 during stirring.

[0043] The implementation principles of Example 2 and Example 1 are similar, so they will not be described in detail here.

[0044] The above are all preferred embodiments of this application, and are not intended to limit the scope of protection of this application. Therefore, all equivalent changes made in accordance with the structure, shape and principle of this application should be covered within the scope of protection of this application.
