Detailed Description
The present invention will be described in further detail with reference to the following drawings and examples, but the invention is not limited thereto.
Referring to the attached drawing 1, the vehicle for recycling the excess road materials comprises a vehicle body 1, a compartment, a Roots blower 2, an electric hydraulic platform 3, a negative pressure air pipe 4, a filter element 5, a positive pressure feeding pipe 7, a negative pressure feeding pipe 8, a positive pressure air pipe 9, a hanging frame 10, a negative pressure material collecting bin 15, a positive pressure material collecting bin 13, a material collecting device 12 and a steel wire rope 11.
The excess material recycling vehicle is used for road surface construction after the synchronous chip sealer vehicle and the rubber-tyred road roller are constructed; the truck body 1 adopts a 6X4 truck, the power of an engine of the truck body is 210kw, a carriage is arranged on a chassis of the truck body 1, and the truck body 1 is divided into a left closed area and a right closed area by a partition board, namely a positive pressure collecting bin 13 and a negative pressure collecting bin 15. The tail part of the vehicle body 1 is provided with a hanging rack 10 so as to be connected with a material collecting device 12.
The material collecting device 12 is a cover body with an opening at the bottom, and the cover body is internally divided into a positive pressure material collecting area 14 and a negative pressure material collecting area 16 by a partition plate. The top of the positive pressure material collecting area 14 is provided with a through hole and is connected with the lower end of the positive pressure material feeding pipe 7, the upper end of the positive pressure material feeding pipe 7 is connected with the positive pressure material collecting bin 13, a branch pipe inclining towards the material collecting device 12 is arranged at the position of the positive pressure material feeding pipe 7 close to the material collecting device 12, and the branch pipe is connected with the outlet of the positive pressure air pipe 9.

The principle of the aggregate device 12 for recovering the excess pavement materials is as follows: the roots fan 2 starts the back, through the burden of taking out of negative pressure trachea 4 for negative pressure aggregate bin 15 and the negative pressure inlet pipe 8 that connect are the negative pressure, and building stones 6 of negative pressure aggregate region 16 below will follow negative pressure inlet pipe 8 and get into negative pressure aggregate bin 15 like this, and the filter core 5 that sets up can avoid the dust that 6 building stones were raised to get into roots fan 2, and this process is the negative pressure process of gathering materials. The positive pressure air flow blown out 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, stone 6 in the positive pressure aggregate area 14 enters the positive pressure feeding pipe 7 according to the air jet principle and is conveyed into the positive pressure aggregate bin 13 by the positive pressure air flow, and the process is a positive pressure aggregate process. In the positive pressure aggregate process, after positive pressure air flow enters the positive pressure aggregate bin 13, the air outlet of the positive pressure aggregate bin 13 needs to be discharged, and in order to avoid bringing out dust in the bin, the air outlet of the positive pressure aggregate bin 13 is also provided with the filter element 5.
According to the positive pressure aggregate process, when positive pressure gas flow enters the positive pressure feed pipe 7 through the branch pipe of the positive pressure feed pipe 7, the positive pressure gas flow must be ensured to flow from bottom to top, therefore, the invention carries out two designs: on one hand, an included angle alpha between the branch pipe and the positive pressure feeding pipe 7 is set to be 25-30 degrees, preferably 30 degrees, so that positive pressure air flow is obliquely upwards sprayed into the positive pressure feeding pipe 7 in the direction of a 30-degree angle; 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 connecting position of the branch pipe and the positive pressure feeding pipe 7, and the one-way valve 701 can only be opened upwards, so that positive pressure air flow can not flow backwards into the positive pressure material collecting area 14.

In actual operation, if the vehicle is actually operated during traveling, two rollers can be arranged at the rear end of the aggregate device 12 to improve the stability of the aggregate device 12.
Further, the pipeline arranged at the tail part of the vehicle body 1 can adopt a hose so as to facilitate the overturning and lifting of the collecting device 12.
The illustrated electro-hydraulic platform 3 includes a first hydraulic motor 301, a hydraulic pump 302, an electric machine, a controller 304, a battery pack 305, a backup generator 306, a hydraulic tank 307, and a second hydraulic motor 308.

The battery pack 305 adopts a lithium battery, and the standby generator 306 can make up for the problem of insufficient electric quantity of the battery pack 305 so as to deal with long-time construction.
In order to clean the equipment when the construction is finished, the positive pressure aggregate bin 13 and the negative pressure aggregate bin 15 can be opened from the tail of the carriage body. The tail part of the positive pressure aggregate bin 13 is provided with a positive pressure aggregate bin rear cover plate 1302, the positive pressure aggregate bin rear cover plate 1302 is connected with the compartment body in a sealing way 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 inlet pipe interface 1301 so as to be connected with a positive pressure inlet pipe 7. When the cleaning is needed, the positive pressure aggregate bin cover plate sealing buckle 1303 is opened, the positive pressure aggregate bin rear cover plate 1302 can be taken down, and the inside of the positive pressure aggregate bin 13 is cleaned by clean water. Similarly, set up negative pressure aggregate bin back shroud 1501 at negative pressure aggregate bin 15's afterbody, negative pressure aggregate bin back shroud 1501 passes through a plurality of negative pressure aggregate bin cover plate seal fastener 1503 and railway carriage or compartment body sealing connection, is equipped with negative pressure inlet pipe interface 1502 on negative pressure aggregate bin back shroud 1501 to connect negative pressure inlet pipe 8, when needing to wash, open negative pressure aggregate bin cover plate seal fastener 1503, can take off negative pressure aggregate bin back shroud 1501, wash in the negative pressure aggregate bin 15 with the clear water.

During the collection process, the vehicle may be traveling at a slower speed, such as 15-20 km/h. After the construction is finished, the second hydraulic motor 308 recovers the steel wire rope, and the aggregate device is pulled up so as to prevent the influence on normal driving. In actual use, other fans can be adopted to replace Roots fans, such as pneumatic conveying equipment such as blowers and the like.
