When the following description refers to the drawings, the same numbers in different drawings represent the same or similar elements unless otherwise indicated. The embodiments described in the following exemplary embodiments do not represent all embodiments consistent with the present disclosure. Instead, they are merely examples of devices consistent with some aspects of the present disclosure as detailed in the appended claims.

[0022] The following will be combined with the drawings in the embodiments of the utility model to clearly and completely describe the technical solutions in the embodiments of the utility model. Based on the embodiments in the utility model, all other embodiments obtained by ordinary technicians in this field without creative work are within the scope of protection of the utility model.

[0023] like Figure 1 , Figure 2 , Figure 3 and Figure 4 As shown, this embodiment provides a vehicle-mounted screening device that is easy to install and disassemble, including a screening assembly, and support assemblies are fixedly installed at both ends of the screening assembly;

[0024] The screening component includes a spine steel pipe 1, on both sides of which are welded a number of screening steel bars 2, in the middle of which a number of screening steel bars 2 are welded a waist beam steel pipe 3, on one side of the bottom end of a number of screening steel bars 2 are welded a bottom beam steel pipe 4, and when the screening steel bars 2 are welded to the spine steel pipe 1, the waist beam steel pipe 3 and the bottom beam steel pipe 4, the spacing between them is not greater than 8 cm to meet the maximum particle size requirement of the building material. When in use, filling materials such as sand and gravel are shoveled to the top of the transport compartment by mechanical equipment such as a forklift or an excavator, and then poured downward, and smaller particles will fall into the interior of the compartment below through the gaps between the screening steel bars 2, and larger particles will slide down to both sides of the vehicle through the screening steel bars 2, and the waist beam steel pipe 3 can reduce the impact deformation of some screening steel bars 2, resulting in gaps greater than 8 cm.

[0025] The support assembly includes a vertical rod 5 fixedly installed at both ends of the spine steel pipe 1 by A bolts, a horizontal rod 6 is welded to the bottom end of the vertical rod 5, and a side rod 7 is welded to the bottom end of both sides of the vertical rod 5. The waist beam steel pipe 3, the spine steel pipe 1 and the bottom beam steel pipe 4 are supported by the support assembly to reduce their deformation caused by impact during use.

[0026] A B bolt fixed to one end of the bottom beam steel pipe 4 is threadedly penetrated on one side of the cross bar 6 , and a C bolt fixed to one end of the waist beam steel pipe 3 is threadedly penetrated on one side of the side bar 7 .

[0027] A slide bar 8 is welded to the bottom end of the screening steel bar 2, and a slide rail 9 is slidably connected to the surface of the slide bar 8. The screening assembly can be directly pulled out through the equipment of the slide rail 9 and the slide bar 8, which makes installation and disassembly more convenient and improves the efficiency of subsequent maintenance by personnel.

[0028] A mounting frame 10 is fixedly connected to one side of the slide rail 9, and a latch seat 11 is fixedly connected to the mounting frame 10 and one end of the slide rod 8. A latch 12 is inserted into the latch seat 11. After the screening assembly is installed on the mounting frame 10, it can be fixed by inserting the latch 12. The mounting frame 10 can be installed on both sides above the carriage without disassembly.

[0029] A threaded hole is provided on one side of the mounting frame 10, and an adjusting bolt 13 is passed through the internal thread of the threaded hole. A bearing 14 is sleeved on one end of the adjusting bolt 13, and the adjusting bolt 13 is rotatably connected to a retaining plate 15 through the bearing 14. A non-slip rubber pad is fixedly connected to one side of the retaining plate 15. The mounting frame 10 is fixed by sleeved on the top ends of both sides of the car body and rotating the adjusting bolt 13 to push the retaining plate 15 inward to clamp the car basket, thereby reducing the time consumed in repeated installation and disassembly.

[0030] Although embodiments of the present invention have been shown and described, it will be appreciated by those skilled in the art that various changes, modifications, substitutions and variations may be made to the embodiments without departing from the principles and spirit of the present invention, and that the scope of the present invention is defined by the appended claims and their equivalents.
