The specific embodiment

Below in conjunction with accompanying drawing the utility model is described in further detail.

As shown in Figure 1, the flexible pavement combined maintenance truck comprises car body 1 and is arranged at the bituminous mixture feed bin 2 on the car body and is arranged at the pavement breaking device 3 of hull back; Shown in Fig. 2,3,4, described pavement breaking device afterbody is provided with and rotates vertical pivot 18, and the lower end of rotating vertical pivot is provided with gear 22; Crushing mechanism base 19 is established on the hull back right side, and the rotating vertical axle sleeve is loaded in the axle sleeve 17 of crushing mechanism base; On the car body below the crushing mechanism base, establish the tooth bar 21 that hydraulic jack 20 drives, tooth bar and the gears engaged of rotating the vertical pivot lower end.Like this, hydraulic jack drives tooth bar, and the rack drives gear rotates, and horizontally rotates thereby drive pavement breaking device 3.Described pavement breaking device 3 adopts the existing crushing mechanism that adopts the digging machine pattern, shown in Fig. 2,3,4.

Shown in Fig. 5,6,7,8,9, above-mentioned flexible pavement combined maintenance truck, car body left side afterbody biasing bituminous mixture grass-hopper 4, bituminous mixture grass-hopper are that scraping plate transmission mechanism, little swing arm 41 and base 42 constitute; Funneling material receiving port 43 is established in bituminous mixture grass-hopper rear end, and front end is a discharging opening; One end of bituminous mixture grass-hopper rear end (funneling material receiving port one end) and little swing arm is with horizontal bearing pin 44 hinge links, the other end of little swing arm and base are with vertical bearing pin 45 hinge links, to guarantee when the bituminous mixture grass-hopper is packed up, to be close to side body, during work, funneling material receiving port can be positioned at bituminous mixture feed bin discharging opening below; Base 42 is fixed in the proceeds posterolateral of car body 1.Described scraping plate transmission mechanism adopts driving device for hydraulic motor 40, chain 51 moving linearlies that equipped sprocket wheel 50 rotated and drive both sides are finished the function of scraper plate discharging from driving scraper plate, this mode of movement, size is little, transfer efficiency is high, is conveying mechanism commonly used in the prior art.The process that bituminous mixture grass-hopper 4 is opened by collapsed state is: at first little swing arm 41 is rotated around vertical bearing pin 45, bituminous mixture grass-hopper 4 also plays rotation with one, when the funneling material receiving port of bituminous mixture grass-hopper during over against bituminous mixture feed bin discharging opening below, little swing arm stops operating.At this moment, the bituminous mixture grass-hopper launches to the left side of car body, as shown in Figure 6.Bituminous mixture grass-hopper 4 begins to rotate around horizontal bearing pin 44 again, at this moment, funneling material receiving port invariant position, the original position rotation, bituminous mixture grass-hopper 4 can launch to the car body rear like this.
