Description

Technical Field

[0001] This utility model relates to the field of building construction technology, specifically to a mixing device for building construction with a crushing structure. Background Technology

[0002] Construction refers to the production activities during the implementation phase of an engineering project. It is the process of building various types of buildings, or the process of turning the lines on the design drawings into physical objects at a designated location. During the construction process, a mixer truck is needed to mix the materials. When recycling concrete, the blocks of concrete need to be crushed and then mixed for reuse.

[0003] The construction mixing device with a crushing structure disclosed in authorization announcement number CN221540212U includes a base plate. A fixed cylinder is fixedly installed on one side of the upper end of the base plate. A mixing motor is fixedly installed at the bottom end of the base plate, and the output end of the mixing motor extends into the interior of the fixed cylinder and is fixedly connected to a rotating shaft. A mixing rod is fixedly installed on the outer wall of the rotating shaft. A vertical plate is fixedly installed at the upper end of the base plate, and a crushing structure is provided on one side of the vertical plate. The crushing structure includes a crushing box, and a drive motor is fixedly installed on one side of the crushing box. The beneficial effect of this utility model after adopting the above technical solution is that it can crush and remix lumps of concrete.

[0004] Although the aforementioned patent can crush and remix blocks of concrete, the crushing and mixing components are completely exposed, with the rotating crushing blades and mixing rods exposed. Operators may suffer mechanical injuries due to accidental contact, and concrete fragments may fly, causing injury to people in the vicinity. During the mixing process, dust and debris are easily scattered, polluting the working environment and affecting workers' health. Utility Model Content

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] like Figure 1-5 As shown, this utility model provides a technical solution:

[0027] A construction mixing device with a crushing structure includes a mixing mechanism comprising a motor 9 fixedly installed at the bottom center of a mixing box 1, and an agitator 10 vertically arranged at the inner center of the mixing box 1. The output shaft of the motor 9 is coaxially connected to the agitator 10. A feed pipe 11 is fixedly installed on the lower right side of the mixing box 1. A guide channel 12 is provided at both the upper and lower ends of the crushing box 2. The bottom guide channel 12 is connected to the left side of the mixing box 1, and the top guide channel 12 is connected to the bottom of the dustproof box 3. The mixing box 1 contains a mixing mechanism. A manual opening and closing mechanism is provided at the upper right side of the mixing box 1. The manual opening and closing mechanism includes an auxiliary material inlet 4 opened at the upper right side of the mixing box 1, and guide rails 5 fixedly installed on the outer sides of the upper end of the auxiliary material inlet 4. A transverse baffle 6 is movably installed between the two guide rails 5. A slider 7 that is slidably connected to the guide rail 5 is fixedly connected on both sides of the baffle 6. A pull rod 8 is fixedly installed on the outer right side of the baffle 6.

[0028] In this embodiment, the dustproof box 3 and the automatic opening and closing mechanism work together to effectively seal the crushing and mixing operation area, solving the problem of dust pollution of the working environment and harm to workers' health in the prior art. The flip plate 17 automatically closes under the action of the spring 23 to form a closed working space, controlling the spread of dust from the source.

[0029] like Figure 2 and Figure 4 As shown, the crushing box 2 is fixedly installed on the upper left side of the mixing box 1. The crushing box 2 contains a crushing mechanism, which includes crushing rollers 13 arranged side-by-side at both ends of the inner side of the crushing box 2 via bearings, and a mounting frame 14 fixedly installed on the outer front side of the crushing box 2. A motor 15 is fixedly installed on the front of the mounting frame 14. Gears 16 are provided at both ends of the outer side of the crushing box 2 near the mounting frame 14. The two gears 16 mesh with each other and are coaxially connected to the two crushing rollers 13 respectively. The output shaft of the motor 15 is coaxially connected to any one of the gears 16. The dustproof box 3 is fixedly installed at the top center of the crushing box 2. A self-contained dustproof box 3 is located at the top upper part of the interior of the dustproof box 3. The automatic opening and closing mechanism includes two flip plates 17 movably installed at both ends of the upper part of the dustproof box 3. The extended ends of the two flip plates 17 are located outside the dustproof box 3 and are fixedly connected to gear 18. Rod seats 19 are fixedly installed on both the upper and lower ends of the dustproof box 3. Vertical guide rods 20 are fixedly connected between the two rod seats 19. Horizontal rods 21 are movably installed outside the two guide rods 20. A horizontal handle 24 is fixedly connected to the outer side of the middle part of the horizontal rod 21. Vertical racks 22 are fixedly connected to both ends of the horizontal rod 21. The racks 22 mesh with the outer side of gear 18. A spring 23 is movably installed between the horizontal rod 21 and the top rod seat 19 and outside the guide rod 20.

[0030] In this embodiment, the integrated design of the crushing box 2 and the dustproof box 3 achieves the effect of physically isolating the rotating crushing roller 13 and the agitator 10, solving the safety hazard of mechanical injury caused by operators accidentally touching high-speed moving parts. The concrete block completes the crushing-mixing process in a closed channel throughout the entire process, eliminating the risk of material splashing.

[0031] Working principle: When the concrete block to be crushed is put into the dust box 3 from the top, its weight acts on the tilting plate 17, causing the tilting plate 17 to overcome the elastic force of the spring 23 and tilt downward. The extension end of the tilting plate 17 drives the gear 18 to rotate. The gear 18 meshes with the rack 22, thereby driving the crossbar 21 to slide downward along the guide rod 20 and compress the spring 23, thus opening the feed port. When the weight of the concrete block is insufficient, it can be manually assisted by the handle 24. Concrete blocks enter the crushing chamber 2 through the material guide channel 12 and are crushed under the action of the counter-rotating crushing rollers 13. The crushed material enters the mixing chamber 1 through the material guide channel 12. At the same time, auxiliary materials can be added by opening the auxiliary material inlet 4 through the sliding baffle 6 via the pull rod 8. The motor 2 9 drives the agitator 10 to mix the material. The mixed material is discharged from the discharge pipe 11. After the feeding is completed, the spring 23 resets and pushes the crossbar 21 to move upward. Through the meshing of the rack 22 and the gear 2 18, the tilting plate 17 is closed to achieve dust prevention and sealing. The whole process realizes continuous operation of crushing and mixing, while effectively controlling dust overflow.

[0032] The foregoing has shown and described the basic principles, main features, and advantages of this utility model. Those skilled in the art should understand that this utility model is not limited to the above embodiments. The embodiments and descriptions in the specification are merely preferred examples and are not intended to limit the utility model.
