Detailed description of the invention
Below in conjunction with the drawings and specific embodiments, the utility model is described in further detail:
As shown in Figure 1,, there is a garbage collection box 2 being installed on vehicle frame 1 in garbage collection box bonnet automatic open-close mechanism for sweeping machine of the present utility model, and this garbage collection box 2 forms chain connection by hinge I 3 and vehicle frame 1, is convenient to upset; The bottom ear seat 2-1 of garbage collection box 2 forms hinged by the piston rod 5-1 of hinge II 4 and hydraulic cylinder 5, the gudgeon 5-2 of hydraulic cylinder 5 carries out hinged with the bearing support 8 being fixed on vehicle frame 1; When work, the piston rod 5-1 of hydraulic cylinder 5 is extrapolated, and garbage collection box 2 is just turned over around hinge I 3, and the sinuous coil 7 that is simultaneously arranged on garbage collection box 2 rear ends is compressed; Now, being fixed on stabilising arrangement 6 on garbage collection box 2 base plates can drive rubbish elevator upper shell 9 around hinge III 10 rotate backward in rubbish elevator lower house 11 (herein the concrete structure of " rubbish elevator " can referring to applicant in the patent " folding type garbage lifting device of back rolling sweeper " of application on March 30th, 2009, the patent No. 200920102344.8); While rubbish elevator upper shell 9 promotes one end spring pull bar 12 hinged with it and moves to right, so the bonnet 2-2 that the spring pull bar 12 moving to right promotes the garbage collection box 2 hinged with its other end wraps the bearing pin 2-3 of page and upwards digs gradually, as shown in Figure 2, the rubbish thing in the most described garbage collection box 2 is all poured out.
After rubbish is finished down, the piston rod 5-1 of hydraulic cylinder 5 shrinks, now garbage collection box 2 overturns forward around hinge I 3, simultaneously drive rubbish elevator upper shell 9 at the 11 interior revolutions of rubbish elevator lower house return gradually by stabilising arrangement 6, and pulling one end spring pull bar 12 hinged with it to move to left, the spring pull bar 12 moving to left pulls the garbage collection box hinged with its other end 2 bonnet 2-2 wrap the bearing pin 2-3 upset downwards of page and cut out gradually.
The structure of stabilising arrangement 6 as shown in Figure 3, is made up of fixed roll bearing 6-1, fixed roll 6-2, drag link mechanism 6-3 and action roller 6-4 etc.; The pulling-rod frame 6-3-1 of fixed roll bearing 6-1, fixed roll 6-2 and drag link mechanism 6-3 one end forms chain connection, pull bar I 6-3-2 and the action roller 6-4 of the drag link mechanism 6-3 other end also form chain connection, are jointly made up of on the outer wall that a quadra is sleeved on this rubbish elevator upper shell 9 like this drag link mechanism 6-3 of fixed roll 6-2, action roller 6-4 and both sides.
The structure of drag link mechanism 6-3 in Fig. 3 as shown in Figure 4, is provided with pull bar I 6-3-2 in pulling-rod frame 6-3-1, is set with spring I 6-3-3 on pull bar I 6-3-2; The left end of this spring I 6-3-3 is provided with spring base I 6-3-4, and it is upper that spring base I 6-3-4 is sleeved on pulling-rod frame 6-3-1, and axially fastened by nut 6-3-5.
In embodiment, in the time that the piston rod 5-1 of hydraulic cylinder 5 releases, garbage collection box 2 can be turned over around hinge I 3, the stabilising arrangement 6 being simultaneously fixed on garbage collection box 2 base plates also can drive rubbish elevator upper shell 9 to rotate backward in rubbish elevator lower house 11 around hinge III 10, at this moment pull bar I 6-3-2 stretches out under the drive of action roller 6-4, spring base I 6-3-4 slippage to the right on pulling-rod frame 6-3-1, spring I 6-3-3 is compressed simultaneously; Because the effect of spring force has strengthened the support force of action roller 6-4 to rubbish elevator upper shell 9, thereby strengthen the stability of rubbish elevator upper shell 9.
Otherwise, in the time that the piston rod 5-1 of hydraulic cylinder 5 shrinks, garbage collection box 2 can overturn forward around hinge I 3, the stabilising arrangement 6 being simultaneously fixed on garbage collection box 2 base plates also can drive rubbish elevator upper shell 9 moving at rubbish elevator lower house 11 interior forwards around hinge III 10, at this moment spring I 6-3-3 stretches, pull bar I 6-3-2 retracts under the effect of spring force, spring base I 6-3-4 slippage left on pulling-rod frame 6-3-1 simultaneously, rubbish elevator upper shell 9 resets rapidly under the effect of pulling force and spring thrust, because the effect of spring force has strengthened the support force of action roller 6-4 to rubbish elevator upper shell 9, thereby strengthen the stability of rubbish elevator upper shell 9.
As shown in Figure 5, spring pull bar 12 is made up of pull bar II 12-1, drag link sleeve 12-2, spring II 12-3, spring base II 12-4, spring base III 12-5, screw 12-6, straight pin 12-7 the structure of the spring pull bar in Fig. 1; Pull bar II 12-1 is set in drag link sleeve 12-2; On drag link sleeve 12-2, be set with spring II 12-3, the two ends of spring II 12-3 are respectively arranged with spring base II 12-4 and spring base III 12-5; Described spring base II 12-4 adopts and is threaded with pull bar II 12-1, and fastening with screw 12-6; It is upper that described spring base III 12-5 is sleeved on drag link sleeve 12-2, and fix with straight pin 12-7; Removable in the rectangular channel 12-8 that straight pin 12-7 offers on drag link sleeve 12-2.
In embodiment, in the time that the piston rod 5-1 of hydraulic cylinder 5 releases, garbage collection box 2 can be turned over around hinge I 3, the stabilising arrangement 6 being simultaneously fixed on garbage collection box 2 base plates can drive rubbish elevator upper shell 9 to rotate backward in rubbish elevator lower house 11 around hinge III 10, and then promotion one end spring pull bar 12 hinged with it moves to right.In the process moving to right at spring pull bar 12, in the time of 90 ° of a <, be subject to the gravity effect of the bonnet 2-2 of garbage collection box 2, spring II 12-3 is first compressed, slippage left in the rectangular channel 12-8 of straight pin 12-7 on drag link sleeve 12-2; Along with spring pull bar 12 continue move to right, in the time of 90 ° of a >, now garbage collection box 2 has been flipped to compared with wide-angle, the gravity effect of bonnet 2-2 reduces, at this moment spring II 12-3 starts to stretch gradually, straight pin 12-7 slides to the right in rectangular channel 12-8 on drag link sleeve 12-2, until slide to the low order end of rectangular channel 12-8; Drag link sleeve 12-2 is shot out under the effect of thrust and spring force, and garbage collection box bonnet 2-2 opens fast and realize self-locking under the effect of spring force, can, because Action of Gravity Field moves down, not guarantee work safety.
Otherwise, in the time that the piston rod 5-1 of hydraulic cylinder 5 shrinks, garbage collection box 2 can overturn forward around hinge I 3, the stabilising arrangement 6 being simultaneously fixed on garbage collection box 2 base plates can drive rubbish elevator upper shell 9 moving at rubbish elevator lower house 11 interior forwards around hinge III 10, and then pulls spring pull bar 12 to move to left.In the process moving to left at spring pull bar 12, in the time of 90 ° of a >, spring II 12-3 is first compressed, slippage left in the rectangular channel 12-8 of straight pin 12-7 on drag link sleeve 12-2; Along with spring pull bar 12 continue move to left, in the time of 90 ° of a <, spring II 12-3 stretches gradually, straight pin 12-7 slides to the right in rectangular channel 12-8 on drag link sleeve 12-2, until slide to the low order end of rectangular channel 12-8, rubbish elevator upper shell 9 resets rapidly under the effect of pulling force and spring thrust, simultaneously, garbage collection box bonnet 2-2 closes and realize self-locking under the effect of spring force, and the effect of inertia not travelled by sweeping machine time and separating guarantees that rubbish can not reveal.
Finally, it is also noted that, what more than enumerate is only a specific embodiment of the present utility model.Obviously, the utility model can also have many distortion, and all distortion that those of ordinary skill in the art can directly derive or associate from the disclosed content of the utility model, all should think protection domain of the present utility model.
