The specific embodiment

Below in conjunction with the accompanying drawing in the utility model embodiment, the technical scheme in the utility model embodiment is clearly and completely described, obviously, described embodiment is only the utility model part embodiment, rather than whole embodiment.Based on the embodiment in the utility model, those of ordinary skills are not making the every other embodiment obtaining under creative work prerequisite, all belong to the scope of the utility model protection.

The new-type locking mechanism of compartment removable garbage truck as shown in Figure 1 and Figure 2, comprise large frame 9, compartment 2 and with the hinged L-type hook arm 1 in one end and compartment 2, the other end of described L-type hook arm 1 is hinged with arm rotating shaft 4, described arm rotating shaft 4 is also hinged with one end of turning rack 5, the other end of described turning rack 5 is provided with the S. A. 8 rotating for turning rack 5, and described S. A. 8 leans with large frame 9; Position near end on described large 9 is fixed with hook arm oil cylinder 3, and described hook arm oil cylinder 3 is hinged with L-type hook arm 1; 2 sides, described compartment are provided with hook 6 near bottom, and the correspondence position of described turning rack 5 is provided with and links up with 6 lock brackets that match 7, between described lock bracket 7 and S. A. 8, is connected by small oil tank 11.The middle part of described lock bracket 7 and turning rack 5 are hinged, and two ends are equipped with locating dowel pin, the middle part hinge-point of described lock bracket 7 and two locating dowel pins Triangle-Profile in obtuse angle; The hinge-point of described lock bracket 7 and little cylinder middle part and near and hook 6 locating dowel pins that match between; Described large 9 is provided with the lock shaft 10 matching with lock bracket 7; Described lock shaft 10 is fixed on large frame 9 by locating piece 12.

The new-type locking mechanism of compartment removable garbage truck as described in Fig. 3 and Fig. 4, in the time of the goods of toppling in compartment 2, when promoting lock bracket 7, pin while linking up with 6 on garbage bin the hydraulic circuit of small oil tank 11 by solenoid directional control valve control, now hook arm oil cylinder 3 promotes hook arm 1 and rotates, hook arm 1 has the trend of rotating around arm rotating shaft 4, on hook arm 1, lift to drive on container and lift, the hook 6 of container drives turning rack 5 to rotate around trip shaft by lock bracket 7 simultaneously, now being equivalent to hook arm 1 and turning rack 5 is connected into one and rotate and cargo box hoisting is unloaded around trip shaft, lock bracket 7 coordinates with extension is enough, prevent turning rack 5 because stressed and rotate, in like manner, hook arm oil cylinder 3 is regained, hook arm 1 and turning rack 5 returns, and container falls.
