Description

Technical Field

[0001] This utility model relates to the field of road construction technology, specifically to a roadbed cement-soil construction device. Background Technology

[0002] In road construction projects, cement slurry or cement powder is forcibly mixed with soft soil to form a stable structural whole, thereby improving the foundation strength and meeting the requirements of road construction.

[0003] The prior art, disclosed in patent document CN216139184U, presents the following technical solution: a roadbed cement-soil construction device, comprising a mixing device, the mixing device including a mixing drum, a support leg connected to the bottom end of the mixing drum, a motor connected to the top end of the mixing drum, and an output rod connected to the output end of the motor. Since the mixing drum is divided into inner and outer groups, the outer mixing drum plays a supporting role, while the inner mixing drum rotates in the opposite direction under the drive of the output rod, thereby improving the mixing effect.

[0004] The above technical solution improves the mixing effect of materials by setting the mixing drum and the output rod to rotate in opposite directions. However, the output rod is not equipped with a structure for feeding materials, which reduces the mixing effect and results in low mixing efficiency. Utility Model Content

[0006] To achieve the above objectives, this utility model provides the following technical solution: a roadbed cement-soil construction device, comprising a support frame and a mixing chamber, wherein the mixing chamber is disposed inside the support frame, a scraper structure is fixedly installed at the upper end of the mixing chamber, and a cement-soil mixing device is installed through the mixing chamber.

[0007] The cement-soil mixing device includes an installation cylinder, which is bolted to the outer walls of both sides of the mixing chamber. A rotating rod is rotatably connected to one end of each of the two rotating rods. Insert rods are fixedly connected to opposite sides of each of the two insert rods.

[0017] As a further preferred embodiment of this technical solution, a protective cover is hinged to the upper end of the support frame, and a handle is provided on the protective cover.

[0018] In the above technical solution, the protective cover can reduce the amount of material splashed out during the cement-soil mixing process, thus reducing material waste, and the handle makes it easy to lift the protective cover.

[0019] This utility model provides a subgrade cement-soil construction device, which has the following beneficial effects:

[0020] (1) By installing a cement-soil mixing device, the present invention arranges spiral mixing blades and mixing plates on a hollow rotating shaft, which can mix cement-soil more evenly and ensure the quality and uniformity of cement-soil.

[0028] The technical solutions of the present invention will be clearly and completely described below with reference to the accompanying drawings of the embodiments of the present invention.

[0029] This utility model provides a technical solution: such as Figure 1 and Figure 2As shown in this embodiment, a roadbed cement-soil construction device includes a support frame 1 and a mixing chamber 12. The mixing chamber 12 is located inside the support frame 1. A protective cover 11 is hinged to the upper end of the support frame 1. The protective cover 11 can reduce the material splashed out during the cement-soil mixing process and reduce material waste. A handle is provided on the protective cover 11. A discharge pipe 13 is provided at the bottom through hole of one end of the support frame 1 and the mixing chamber 12. A valve is provided on the discharge pipe 13. A scraper structure 2 is fixedly installed at the upper end of the mixing chamber 12. A cement-soil mixing device 3 is installed through the mixing chamber 12.

[0030] like Figure 3 and Figure 5 As shown, the scraping structure 2 includes a mounting frame 21, which is located on the top side of both ends of the mixing chamber 12. A threaded rod 22 is mounted inside one mounting frame 21 via a bearing. A drive motor is mounted at one end of the threaded rod 22 and is electrically connected to an external control switch. A guide rod 23 is fixedly connected inside the other mounting frame 21. Movable blocks 24 are fitted onto the outer walls of both the threaded rod 22 and the guide rod 23. An arc-shaped scraper 25 is bolted to the bottom side of each movable block 24. The arc-shaped scraper 25 is detachable for easy replacement. The outer wall of the arc-shaped scraper 25 slides against the inner wall of the mixing chamber 12. By installing the scraping structure 2, the mixed cement-soil is discharged through the discharge pipe 13 and valve. The threaded rod 22 and guide rod 23 cause the arc-shaped scraper 25 to move along the inner wall of the mixing chamber 12, scraping away the cement-soil adhering to the inner wall of the mixing chamber 12. This not only reduces cement-soil waste but also facilitates cleaning of the mixing chamber 12.

[0031] like Figure 2 and Figure 4As shown, the cement-soil mixing device 3 includes an installation cylinder 31, which is bolted to the outer walls of both sides of the mixing chamber 12. A rotating rod 37 is rotatably connected to one end of each of the installation cylinder 31. A mixing motor 32 is mounted on the outer end of one of the rotating rods 37 via a flange. The mixing motor 32 is electrically connected to an external control switch. The model of the mixing motor 32 is YBX3. Insert rods 33 are fixedly connected to the opposite sides of the two rotating rods 37. A hollow rotating shaft 34 is inserted between the two insert rods 33. Threaded holes 35 are provided at both ends of the hollow rotating shaft 34 and on the insert rods 33. Bolts 36 are installed between the threaded holes 35. Connecting shafts 34 are arranged on the hollow rotating shaft 34. 1. Spiral mixing blades 342 are fixedly connected to the outer surface of the connecting shaft 341. Adjacent spiral mixing blades 342 are staggered. Mixing plates 343 are fixedly connected to the top side of the connecting shaft 341. By installing a cement-soil mixing device, the spiral mixing blades 342 and mixing plates 343 are arranged on the hollow rotating shaft 34, which can mix the cement-soil more evenly and ensure the quality and uniformity of the cement-soil. This method is more efficient than the mixing method in the comparative document. In addition, the spiral mixing blades 342 and mixing plates 343 are installed on the hollow rotating shaft 34 and fixed between two plug rods 33 by plugging, which facilitates the subsequent disassembly and maintenance of the spiral mixing blades 342 and mixing plates 343.

[0032] This utility model provides a roadbed cement-soil construction device. The specific working principle is as follows: During roadbed construction, cement-soil needs to be mixed. The materials for making cement-soil are added into the mixing chamber 12 according to a certain ratio, and the protective cover 11 is placed on top. During mixing, the mixing motor 32 is started via an external control switch, driving the rotating rod 37 to rotate, which in turn drives the insert rod 33 and the hollow rotating shaft 34 to rotate, causing the spiral mixing blades 342 and the mixing plate 343 to rotate, thereby ensuring thorough mixing of the materials. After mixing is completed, the mixing motor 32 is stopped, and the valve on the discharge pipe 13 is opened to discharge the cement-soil. After discharge, the drive motor is started via an external control switch. The machine causes the threaded rod 22 to rotate, causing the movable blocks 24 at both ends to move on the threaded rod 22 and the guide rod 23, thereby driving the arc-shaped scraper 25 to move along the inner wall of the mixing chamber 12, which can scrape the adhering cement soil into the discharge pipe 13 for discharge. In order to clean and maintain the spiral mixing blades 342 and the mixing plate 343, they can be disassembled, that is, the flange between the mixing motor 32 and the rotating rod 37 can be removed, then the bolts connecting the mounting cylinder 31 and the support frame 1 can be removed, and the bolts 36 can be removed, so that the insert rod 33 can be taken out from both ends of the hollow rotating shaft 34, and then the spiral mixing blades 342 and the mixing plate 343 can be disassembled.

[0033] Although embodiments of the present invention have been shown and described, it will be understood by those skilled in the art that various changes, modifications, substitutions and alterations can be made to these embodiments without departing from the principles and spirit of the present invention, the scope of which is defined by the appended claims and their equivalents.
