[0026] The excess material recycling vehicle is used for road surface construction after the synchronous stone sealing vehicle and rubber tire road roller construction; the vehicle body 1 adopts a 6X4 cargo vehicle, the engine power of which is 210kw, the carriage is installed on the chassis of the vehicle body 1, the vehicle body 1 is divided into left and right two closed areas by a partition plate, which are the positive pressure material collecting bin 13 and the negative pressure material collecting bin 15 respectively. The tail of the vehicle body 1 is provided with a hanger 10, so as to be connected with the material collecting device 12.

[0027] The Roots blower 2 and the electric hydraulic platform 3 are arranged at the front of the carriage, the negative pressure air pipe 4 is connected with the negative pressure interface of the Roots blower 2 at one end and connected with the negative pressure aggregate bin 15 at the other end, and the filter core 5 is arranged on the negative pressure air pipe 4 to avoid dust and sundries entering the Roots blower 2. The positive pressure air pipe 9 is connected with the positive pressure interface of the Roots blower 2 at one end and connected with the positive pressure feeding pipe 7 arranged at the tail of the vehicle body 1 at the other end.

[0028] The aggregate device 12 is a cover body with an open bottom, and the cover body is divided into the positive pressure aggregate area 14 and the negative pressure aggregate area 16 by a partition plate. The positive pressure aggregate area 14 is provided with a through hole at the top and connected with the lower end of the positive pressure feeding pipe 7, the upper end of the positive pressure feeding pipe 7 is connected with the positive pressure aggregate bin 13, and the position of the positive pressure feeding pipe 7 close to the aggregate device 12 is provided with a branch pipe inclined towards the aggregate device 12, and the branch pipe is connected with the outlet of the positive pressure air pipe 9. The negative pressure aggregate area 16 is provided with a through hole at the top and connected with the lower end of the negative pressure feeding pipe 8, and the upper end of the negative pressure feeding pipe 8 is connected with the negative pressure aggregate bin 15.

[0029] The principle of the aggregate device 12 for recycling the pavement surplus material is that, after the Roots blower 2 is started, the negative pressure is formed in the negative pressure aggregate bin 15 and the negative pressure feeding pipe 8 through the negative pressure air pipe 4, so that the stones 6 below the negative pressure aggregate area 16 enter the negative pressure aggregate bin 15 along the negative pressure feeding pipe 8, and the filter core 5 arranged can avoid the dust raised by the stones 6 from entering the Roots blower 2, and the process is the negative pressure aggregate process. The positive pressure airflow blown by the Roots blower 2 is sprayed into the positive pressure feeding pipe 7 through the branch pipe of the positive pressure feeding pipe 7 and flows upwards, according to the air jet principle, the stones 6 in the positive pressure aggregate area 14 enter the positive pressure feeding pipe 7 and are sent into the positive pressure aggregate bin 13 by the positive pressure airflow, and the process is the positive pressure aggregate process. In the positive pressure aggregate process, the positive pressure airflow needs to be discharged from the air outlet of the positive pressure aggregate bin 13 after entering the positive pressure aggregate bin 13, and in order to avoid the dust in the bin from being taken out, the filter core 5 is further arranged at the air outlet of the positive pressure aggregate bin 13.

[0030] According to the positive pressure aggregate process, when the positive pressure airflow enters the positive pressure feeding pipe 7 through the branch pipe of the positive pressure feeding pipe 7, it must be ensured to flow from bottom to top, and for this purpose, two designs are made in the application: on the one hand, the included angle a between the branch pipe and the positive pressure feeding pipe 7 is set to 25°~30°, preferably 30°, so that the positive pressure airflow is sprayed into the positive pressure feeding pipe 7 at an angle of 30°; on the other hand, a one-way valve 701 is arranged in the positive pressure feeding pipe 7, the one-way valve 701 is arranged below the connection position of the branch pipe and the positive pressure feeding pipe 7, and the one-way valve 701 can only open upwards, so that the positive pressure airflow cannot flow back into the positive pressure aggregate area 14.

[0031] Further, the front end of the aggregate device 12 is provided with a support arm 17, which is rotationally connected with the hanger 10 arranged at the tail of the vehicle body 1, and the rear end of the aggregate device 12 is connected with a traction mechanism on the vehicle body 1, which can be a steel wire rope 11 traction mechanism, one end of the steel wire rope 11 being connected with the rear end of the aggregate device 12, and the other end of the steel wire rope 11 being wound and fixed on a winding drum arranged at the front of the vehicle compartment, the rotation of the winding drum being driven by the electric hydraulic platform 3 to realize the lifting and falling of the aggregate device 12.

[0032] In actual operation, if the operation is performed during the vehicle running, two rollers can be additionally arranged at the rear end of the aggregate device 12 to improve the stability of the aggregate device 12.

[0033] Further, the pipeline arranged at the tail of the vehicle body 1 can be a hose to facilitate the overturning of the aggregate device 12.

[0034] The electric hydraulic platform 3 comprises a first hydraulic motor 301, a hydraulic pump 302, an electric motor, a controller 304, a battery pack 305, a standby generator 306, a hydraulic oil tank 307 and a second hydraulic motor 308. The hydraulic pump 302 is connected with the hydraulic oil tank 307, the first hydraulic motor 301 and the second hydraulic motor 308, the electric motor is connected with the hydraulic pump 302 to drive the hydraulic pump 302 to drive the first hydraulic motor 301 and the second hydraulic motor 308 to operate, the first hydraulic motor 301 is used to drive the rotation of the Roots blower 2, and the second hydraulic motor 308 is used to drive the rotation of the winding drum of the steel wire rope 11 traction mechanism to control the lifting and falling of the aggregate device 12. The battery pack 305 adopts lithium batteries, and the standby generator 306 can compensate for the insufficient power of the battery pack 305 to cope with long-term construction.

[0035] In order to clean the equipment when the construction is completed, the positive pressure aggregate bin 13 and the negative pressure aggregate bin 15 can be opened from the tail of the compartment. The positive pressure aggregate bin rear cover plate 1302 is arranged at the tail of the positive pressure aggregate bin 13, the positive pressure aggregate bin rear cover plate 1302 is sealed and connected with the compartment through a plurality of positive pressure aggregate bin cover plate sealing buckles 1303, and the positive pressure aggregate bin rear cover plate 1302 is provided with a positive pressure feeding pipe interface 1301 to connect the positive pressure feeding pipe 7. When cleaning is needed, the positive pressure aggregate bin cover plate sealing buckle 1303 is opened, and the positive pressure aggregate bin rear cover plate 1302 can be removed, and the positive pressure aggregate bin 13 is cleaned with clean water. Similarly, the negative pressure aggregate bin rear cover plate 1501 is arranged at the tail of the negative pressure aggregate bin 15, the negative pressure aggregate bin rear cover plate 1501 is sealed and connected with the compartment through a plurality of negative pressure aggregate bin cover plate sealing buckles 1503, and the negative pressure aggregate bin rear cover plate 1501 is provided with a negative pressure feeding pipe interface 1502 to connect the negative pressure feeding pipe 8. When cleaning is needed, the negative pressure aggregate bin cover plate sealing buckle 1503 is opened, and the negative pressure aggregate bin rear cover plate 1501 can be removed, and the negative pressure aggregate bin 15 is cleaned with clean water.

[0036] The specific construction process is as follows: after the synchronous chip seal vehicle and the rubber-tired road roller are constructed, the second hydraulic motor 308 is used to drive the drum of the steel wire rope traction mechanism to release the steel wire rope 11, and due to the action of gravity, the aggregate collecting device 12 rotates downward around the rotating connecting shaft of the support arm 17 and the hanger 10 to reach a suitable position, and then the second hydraulic motor 308 stops working, and the position of the aggregate collecting device 12 is locked, and then the first hydraulic motor 301 is started to start the Roots blower 2 to collect the remaining materials on the road surface. During the collection process, the vehicle can walk at a slow speed, such as a speed of 15-20 km / h. After the construction is completed, the steel wire rope is recovered by the second hydraulic motor 308 to pull up the aggregate collecting device to prevent affecting normal driving. In actual use, other blowers can be used to replace the Roots blower, such as air blower and the like.
