DETAILED DESCRIPTION

[0024] 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. Obviously, the described embodiments are only part of the embodiments of the utility model, not all of the embodiments. 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.

[0025] See also Figures 1 to 7 In an embodiment of the utility model, a 3D asphalt paving device includes a paver 100, which includes a vehicle bottom plate 110. A slide groove 111 is provided on the bottom surface of the vehicle bottom plate 110. A road surface cleaning mechanism 200 is slidably connected inside the slide groove 111. The road surface cleaning mechanism 200 includes two cleaning units 210. The two cleaning units 210 each include a slider 211. The outer wall of the slider 211 is slidably connected to the inside of the slide groove 111. A round tube 212 is fixedly connected to the bottom surface of the slider 211. A round rod 213 is rotatably sleeved on the bottom surface of the round tube 212. A gear is sleeved and fixed to the outer wall of the round rod 213. A cleaning brush 216 is fixedly sleeved on the outer wall of the round rod 213 located below the gear 1 214, and a motor seat 215 is sleeved and fixedly mounted on the outer walls of the two round tubes 212. The interiors of the two motor seats 215 are fixedly connected with motors 1 220, and the motor shafts of the two motors 1 220 are transmission-connected with gears 221, and the two gears 221 are respectively meshed with the two gears 1 214 for transmission. The bottom surface of the vehicle floor 110 is fixedly connected with a collecting box 300, and the outer wall of the round rod 213 near the bottom end is rotationally connected with a rotating rod 260, and the other end of the rotating rod 260 is fixedly connected with an auxiliary wheel 261.

[0026] Specifically, the road cleaning mechanism 200 is located in front of the paving mechanism, and the motor shafts of the two motors 220 are driven in reverse to the two gears 221 respectively. The two gears 221 are respectively meshed with the two gears 1 214 for transmission, so that the two cleaning brushes 216 rotate in opposite directions. When the two cleaning brushes 216 rotate in opposite directions, they can form a "clamping" effect, pushing debris and stones to the side or rear more effectively to prevent debris from splashing forward. This opposite movement can generate a combined force, making the cleaning process more efficient. The auxiliary wheel 261 is used to support the round rod 213. Embodiment 1

[0027] like Figure 5-7As shown, in the present embodiment, the collection box 300 comprises a box body 310, two fixing frames 320 are symmetrically fixed on the top surface of the box body 310, the top surfaces of the two fixing frames 320 are fixedly connected to the bottom surface of the vehicle floor 110, a pipe 311 and a storage cavity 312 are provided inside the box body 310, two transmission shafts 330 and a rotating shaft 1 340 are rotatably connected inside the pipe 311, the transmission shaft 330 and the rotating shaft 1 340 are both rotatably connected to the outer wall of the box body 310, an electric conveyor belt 331 is transmission-connected between the two transmission shafts 330, a guide brush 341 is sleeved and fixed on the outer wall of the rotating shaft 1 340, a gear 342 is sleeved and fixed on the outer wall of the rotating shaft 1 340 located on the outer wall of the box body 310, a motor seat 350 is fixedly connected to the outer wall of the box body 310, and a motor 351 is fixedly connected to the top surface of the motor seat 350 The motor shaft of motor three 351 is transmission connected to one end of rotating shaft one 340, the outer wall of motor seat three 350 is fixed to the box body 310 and is rotatably connected to rotating shaft two 360, the outer wall of rotating shaft two 360 is sleeved and fixed with gear four 361, gear four 361 and gear three 342 are meshed for transmission, the rotating shaft two 360 and the transmission shaft 330 are transmission connected with pulley two 333, a plurality of guide plates 332 are fixedly connected at equal distances on the surface of the electric conveyor belt 331, and the box body 310 is provided with an openable box door at the bottom of a storage cavity 312.

[0028] In this embodiment, the collecting box 300 is opened between the road cleaning mechanism 200 and the paving mechanism, the inlet of the pipe 311 is located at the rear of the road cleaning mechanism 200, and the motor shaft of the driving motor 351 is driven to the guide brush 341 to rotate the guide brush 341. When the cleaning brush 216 sweeps the debris to the entrance of the pipe 311, it will be brought into the pipe 311 by the rotating guide brush 341 and fall on the electric conveyor belt 331. When the rotating shaft 1 340 rotates, the gear 3 342 and the gear 4 361 The transmission shaft 330 rotates under the action of the second pulley 333 in meshing transmission, so that the electric conveyor belt 331 carries the sundries to the storage chamber 312. Since a number of guide plates 332 are fixedly connected to the surface of the storage chamber 312, rounder objects such as pebbles can be stuck between the guide plates 332 and taken away. The rotating electric conveyor belt 331 will send the sundries into the storage chamber 312 for storage, and then open the box door at the bottom of the storage chamber 312 to clean out the sundries. Embodiment 2

[0029] On the basis of the first embodiment, in order to make up for the problem that the distance between the two cleaning brushes 216 in the first embodiment is too large and the cleaning range is limited.

[0030] like Figure 2-4As shown, in this embodiment, the outer walls of the two round tubes 212 are transmission connected with a pulley 1 230, and a square sleeve 240 is fixedly sleeved on the middle part of one side of the pulley 1 230, and the side wall of the square sleeve 240 is fixedly connected with a connecting rod 241, and the end of the connecting rod 241 is screwed and connected with a reciprocating screw rod 242, and the two ends of the reciprocating screw rod 242 are respectively rotatably connected with a fixed block 1 243 and a fixed block 244, and the top surfaces of the fixed block 1 243 and the fixed block 244 are fixedly connected to the bottom surface of the vehicle bottom plate 110, and the bottom surface of the slide groove 111 is fixedly connected with a motor seat 246, and the inner wall of the motor seat 246 is fixedly connected with a motor 245, and the motor shaft of the motor 245 is transmission connected to one end of the fixed block 244, and a reset spring 250 is fixedly connected between the two sliders 211.

[0031] During specific implementation, while the cleaning brush 216 rotates and cleans, the motor shaft of the driving motor 245 is transmitted to the reciprocating screw 242, causing the reciprocating screw 242 to rotate, and the connecting rod 241 reciprocates along the outer wall of the reciprocating screw 242 as the reciprocating screw 242 rotates. When the connecting rod 241 moves forward, it will pull the pulley 1 230, causing the two sliders 211 to slide in the slide groove 111 and approach each other. As the connecting rod 241 moves back, the pulley 1 230 is gradually not pulled. At this time, the two sliders 211 will separate from each other under the elastic force of the return spring 250 and return to their initial positions. As the connecting rod 241 reciprocates on the outer wall of the reciprocating screw 242, the two cleaning brushes 216 will approach and then move away from each other while rotating and cleaning, thereby increasing the cleaning range.

[0032] It is obvious to those skilled in the art that the present invention is not limited to the details of the exemplary embodiments described above, and that the present invention can be implemented in other specific forms without departing from the spirit or essential features of the present invention. Therefore, the embodiments should be regarded as exemplary and non-restrictive from any point of view, and the scope of the present invention is defined by the appended claims rather than the above description, and it is intended that all changes falling within the meaning and scope of the equivalent elements of the claims be included in the present invention. Any reference numeral in a claim should not be regarded as limiting the claim to which it relates.

[0033] In addition, it should be understood that although the present specification is described according to implementation modes, not every implementation mode contains only one independent technical solution. This description of the specification is only for the sake of clarity. Those skilled in the art should regard the specification as a whole. The technical solutions in each embodiment may also be appropriately combined to form other implementation modes that can be understood by those skilled in the art.
