Abstract

The utility model provides an improved garbage bin lifting and turning over mechanism for a rear loading and compacting garbage vehicle, which comprises an oil cylinder, a rotating shaft, a lifting frame, a transverse beam, an overturning channel plate and a hook. The utility model is characterized in that the hook is hinged on a cross beam by a pivot shaft, the top of the cross beam is provided with a triangular limited block, and a restoring spring is arranged between the lower part of the hook and the bottom of the cross beam. After the utility model is adopted, the rotating radius of a garbage bin can be shortened under the condition that the tail section of a garbage vehicle is lengthened differently, and the case that the garbage bin hits against a garbage carriage to hide a door of the garbage carriage is avoided, so shortages in the prior art are solved effectively.

Description

Back dress compression garbage truck sewage disposer promotes switching mechanism

The utility model is that a kind of improved back dress compression garbage truck sewage disposer promotes switching mechanism.

Along with the development of urban construction, delivery draws the vehicle of rubbish progressively to use the bigger back dress compression garbage truck of carrying capacity.The afterbody portion of this waste-skip is equipped with a sewage disposer as shown in Figure 1 and promotes switching mechanism.This mechanism is mainly by oil cylinder 1, raising legs 2, S. A. 6, crossbeam 3, upset frid 5 with link up with 4 and form.Two oil cylinders 1 are articulated in the both sides, lower end of dumping waggon rear end hopper 8 respectively, S. A. 6 is installed on the end of hopper 8, raising legs 2 is installed on the S. A. 6 with the slotted hole 7 on its top, the piston rod of oil cylinder 1 is connected with raising legs 2, crossbeam 3 is connected in the end of two raising legss 2, two hooks 4 are installed on the dried crossbeams 3, and a upset frid 5 that has deep-slotted chip breaker also is housed on S. A. 6, and a guide wheel 9 with the deep-slotted chip breaker socket is housed on raising legs 2.This mechanism is work like this: after the hangers of sewage disposer 10 hangs on the hook 4, start oil pump, the piston rod of oil cylinder 1 travels forward, drive raising legs 2 and rise, when the bottom of the slotted hole 7 of raising legs 2 touched S. A. 6, raising legs 2 stopped to rise, and rotate sewage disposer 10 upsets around S. A. 6, when the guide wheel 9 of raising legs 2 moves to it when terminal along deep-slotted chip breaker, raising legs 2 has overturn 180 °, and the rubbish in the sewage disposer 10 are poured in the hopper 8.When oil cylinder 1 emptying, sewage disposer 10 just returns frame ground by former path of motion and finishes the whole rubbish process of unloading.Find that in use there is following weak point in this mechanism; When sewage disposer 10 rose to hopper 8 tops upsets and tips rubbish, staving often bumped the plate of covering to the waste-skip casing, not only sends bigger clash, and damage rubbish container easily cover plate mechanism.If with waste-skip afterbody lengthening, exceed the full-length of standing order again, can't implement.

The purpose of this utility model is to solve the deficiency of prior art, and a kind of waste-skip afterbody that need not extend is provided, and makes sewage disposer not collide the back dress compression garbage truck sewage disposer lifting switching mechanism that rubbish container shuts the door again.

Fig. 1 is that existing back dress compression garbage truck sewage disposer promotes switching mechanism.

Fig. 2 is the scheme drawing of the utility model concrete structure.

Fig. 3 is the constitution diagram after the utility model upset.

Task of the present utility model is achieved in that as shown in Figure 2 this mechanism includes oil Cylinder 1, rotating shaft 6, hoisting frame 2, crossbeam 3, upset frid 5 and hook 4, its feature Be that hook 4 is articulated on the crossbeam 3 by a pivot 11, is provided with one at crossbeam 3 tops Individual leg-of-mutton limited block 12 is provided with one again between hook 4 bottoms and crossbeam 3 bottoms Position spring 13.

Because the utility model has been done above-mentioned improvement, when raising legs 2 rises and is turned to a certain degree, hook 4 is just rotated downward-sloping again around pivot 11 together with sewage disposer 10 under the action of gravity of sewage disposer 10, till limiting stopper 12 is close in hook 4, (as shown in Figure 3), this shows, the utility model sewage disposer upset radius is just little than prior art upset radius (seeing dotted portion among Fig. 3), therefore the thing that can avoid sewage disposer collision rubbish container to shut the door under the situation of waste-skip afterbody that need not extend takes place, thereby has overcome the deficiency of prior art effectively.When sewage disposer 10 fell after rise, under the effect of retracing spring 13, the sidewall that crossbeam 3 is close in hook 4 again was returned to initial position.When implementing, the angle of leg-of-mutton limiting stopper 12 and hook 4 with 20-30 ° for well.

Claims
