[0029] like Figure 1 , Figure 2 and Figure 3 As shown, a small and lightweight vacuum cleaner cart includes a welding suction cup 4, caster assemblies 1, and a U-shaped handle 3. The welding suction cup 4 includes a main support body 401 and an air duct 406. The air duct 406 is vertically mounted on and passes through the main support body 401, with the other end connected to the material bin of the engineering vehicle. Two caster assemblies 1 are symmetrically mounted on both sides of the main support body 401 for movement. The U-shaped handle 3 is mounted on the main support body 401 for the operator to push and pull the vacuum cleaner cart. The caster assemblies 1 and the U-shaped handle 3 drive the entire vacuum cleaner cart to move. During movement, under the action of suction, milling materials and other materials from the road surface are sucked into the material bin of the engineering vehicle through the air duct 406 of the welding suction cup 4, thereby achieving the function of cleaning the road surface.

[0030] In some embodiments, such as Figure 1 , Figure 2 and Figure 3As shown, the lower outer periphery of the main support body 401 is provided with a baffle, and the upper middle part is provided with a fixing plate. The air duct 406 is installed in the middle of the fixing plate. A rubber plate is installed on the baffle by a pressure plate and bolts. Specifically, a short baffle 402 is welded to the front end of the main support body 401, and an integrated U-shaped baffle 403 is welded to the left and right sides and the rear end of the main support body 401. A left fixing plate 404 and a right fixing plate 405 are welded to the left and right sides of the upper middle part of the main support body 401, respectively. The air duct 406 is welded in the middle position between the left fixing plate 404 and the right fixing plate 405. Caster brackets 407 are symmetrically welded to the two edges of the main support body 401. A stiffening plate 408 is welded to the middle position of the caster bracket 407 to strengthen the structure. The entire welded suction cup 4 has a conical structure with a smooth bottom conical surface. The suction cup has low ventilation resistance and high air volume utilization, which can effectively suck materials such as milled road materials into the air duct and prevent material jamming.

[0031] In some embodiments, such as Figure 6 As shown, the welding suction cup 4 has a short rubber plate 5 at its front end. The front pressure plate 6 is connected to the short rubber plate 5 and the short baffle 402 at the front end of the welding suction cup 4 by bolts, firmly fixing the short rubber plate 5 to the front end of the welding suction cup 4. The welding suction cup 4 has integrated U-shaped long rubber plates 7 on its left and right sides and rear end. The rear pressure plate 8 is connected to the long side of the U-shaped long rubber plate 7 and the U-shaped baffle 403 by bolts. The two side pressure plates 9 are connected to the short side of the U-shaped long rubber plate 7 and the U-shaped baffle 403 by bolts, respectively, to fix the U-shaped long rubber plate 7. The short rubber plate 5 and the U-shaped long rubber plate 7 are firmly fixed around the welding suction cup 4, with their lower ends flush and a height of 25mm from the ground. This allows the suction trolley to gather materials such as road milling material during operation, thereby efficiently sucking the ground material into the air duct 406 and into the suction trolley's material bin.

[0032] In some embodiments, such as Figure 4 , Figure 5 and Figure 6 As shown, the caster assembly 1 includes a caster axle 101, a caster 102, a bushing 103, and a positioning nut 104;

[0033] The caster axle 101 is connected to the caster bracket 407 by welding. The caster 102 is fitted onto the caster axle 101. One end of the caster 102 is axially positioned by a shoulder on the caster axle 101, restricting the caster 102 from moving inward along the caster axle 101. The bushing 103 is fitted onto the caster axle 101 and is locked against the other end of the caster 102, restricting the caster 102 from moving outward along the caster axle 101. The positioning nut 104 is connected to the caster axle 101 by a threaded connection. The positioning nut 104 is locked against one end of the bushing 103, providing axial positioning. The caster 102 is easy to disassemble and replace.

[0034] In some embodiments, such as Figure 1 , Figure 2 and Figure 3 As shown, the main support body 401 is welded with a left handrail bracket 409 and a right handrail bracket 410 near the caster bracket 407. Welding plates 2 are welded to both ends of the U-shaped handrail 3. The welding plates 2 are connected to the left handrail bracket 409 and the right handrail bracket 410 by bolts. The U-shaped handrail 3 forms a 60° angle with the horizontal plane, which is in line with the operator's pushing and pulling angle, making it convenient for the operator to push and pull the trolley.

[0035] This utility model relates to a small and lightweight vacuum cleaner trolley, which can clean materials such as milled material on a small area of ​​the road. After the air duct of the vacuum cleaner trolley is connected to the material bin of the engineering vehicle, the operator can hold the U-shaped handle of the vacuum cleaner trolley and push or pull it forward to move the vacuum cleaner trolley over the materials such as milled material on the road. The material is sucked into the air duct by the welded suction cup and then enters the material bin of the engineering vehicle to complete the cleaning work.

[0036] Furthermore, those skilled in the art will understand that although some embodiments described herein include certain features found in other embodiments but not others, combinations of features from different embodiments are also within the scope of protection of this utility model and form different embodiments. For example, in the embodiments described above, those skilled in the art can use them in combination based on known technical solutions and the technical problems to be solved by this application.
