Specific embodiment
Each preferred embodiment of the utility model is described below with reference to accompanying drawings.It provides referring to attached
The description of figure, to help the understanding to the example embodiment of the utility model as defined by appended claims and their equivalents.
It includes the various details for helping to understand, but they can only be counted as illustratively.Therefore, those skilled in the art will
It recognizes, embodiment described herein can be made various changes and modifications, without departing from the scope of the utility model and essence
Mind.Moreover, in order to keep specification more clear succinct, by omission pair it is well known that the detailed description of function and construction.
As shown in Figure 1, a kind of compression type garbage truck butt buster structure, comprising: oil cylinder 1, support 5, Dalian lever arm 2, small rod
Arm 3 hangs can hook seat 4 and hangs can hook 6;The oil cylinder 1 and the support 5 are separately fixed at the compression type garbage truck tail portion,
Using garbage truck tail portion as fulcrum;3 both ends of small rod arm are pivoted with the support 5 and the upper end for hanging can hook seat 4 respectively
Connection;The Dalian lever arm 2 includes pivot 11 under pivot 10 on the lever arm of Dalian and Dalian lever arm, the Dalian lever arm
Lower pivot 11 is connect with the compression type garbage truck tail portion, pivot 10 and the extension can hook seat on the Dalian lever arm
4 middle part is pivotally connected;The Dalian lever arm 2 10 end of pivot on the lever arm of Dalian is equipped with the connection sheet extended downwardly, institute
The piston rod end and the connection sheet for stating oil cylinder 1 are pivotally connected;The extension can hook 6 is placed in 4 bottom of extension can hook seat, suspension
Dustbin.
It drives Dalian lever arm 2 and small rod arm 3 to rotate around support 5 by 1 expanding-contracting action of oil cylinder, and then drives and hang can hook seat
4 movements;Longer than small rod arm 3 in view of Dalian lever arm 2, amplitude of fluctuation is relatively large, therefore oil cylinder 1 drives Dalian lever arm 2 logical
10 relative seat 5 of pivot rotates on excessive link arm, drives and hangs the rising of can hook seat 4, in view of 4 middle part of extension can hook seat and Dalian
Lever arm 2 is pivotally connected, and hanging can hook seat 4 will be rotated by the relatively large link arm 2 of pivot 11 under the lever arm of Dalian, so it is vertical on
It rises;Hanging can hook seat 4 simultaneously pulls small rod arm 3 to rotate by pivot 12 on small rod arm around support 5;And small rod arm 3
It is relatively short, the upper end for hanging can hook seat 4 will be pullled when it is turning, by pivot 13 under small rod arm with respect to small rod
Arm 3 rotates, while making it through the relatively large link arm 2 of pivot 11 under the lever arm of Dalian and substantially rotating, and then entirety is overturn;Cause
Pass through for dustbin 9 and be placed in the suspension of hook 6 for hanging 4 bottom of can hook seat, when hanging the overturning of can hook seat 4, dustbin 9 will be followed and be turned over
Turn, to realize the operation dumped rubbish into garbage truck.
The Dalian lever arm 2 includes: first connecting portion and second connecting portion;The first connecting portion and 5 pivot of support
Turn connection;It is pivotally connected in the middle part of the second connecting portion and the extension can hook seat 4;The first connecting portion and second connection
The convergence part in portion and the piston rod end of the oil cylinder 1 are pivotally connected;The folder of the first connecting portion and the second connecting portion
Angle α is greater than 90 °.
The small rod arm 3 includes: third interconnecting piece and the 4th interconnecting piece;The third interconnecting piece and 5 pivot of support
Turn connection;4th interconnecting piece is pivotally connected with 4 upper end of extension can hook seat;The third interconnecting piece and the 4th connection
The angle β < α in portion.
Narrow in view of the trailing space of compression type garbage truck, the amplitude of fluctuation for hanging can hook seat 4 is very big, dynamic in order to avoid overturning
It mutually collides with when making, it is preferred that hang and open up fillet at the top of can hook seat 4, diameter is less than the width of support 5;To not influence
Under the premise of rotary movement, the area for hanging 4 top swinging track of can hook seat is reduced, reduces risk of colliding with.
Two lifting lugs up and down are usually arranged in dustbin 9, and overturning is to be capable of fixing dustbin 9;It is steady when in order to enable overturning
It is fixed happy to tangle dustbin 9;Preferably, hanging can hook 6 includes: upper hook 7 and lower draw-bar 8;7 opening direction of upper hook vertically to
On, the gravity for enabling to carry dustbin 9 stablizes extension bucket;8 opening direction of lower draw-bar and vertical direction are at an acute angle;Work as rubbish
When rubbish bucket 9 is with the overturning of can hook seat 4 is hung, outwardly directed lower draw-bar 8 is easier to be engaged with the lower hanging groove of dustbin 9, preferably tangles
The lower hanging groove of dustbin, thus fixed dustbin 9.
When dustbin 9 is with the overturning of can hook seat 4 is hung more than horizontal position, dustbin 9 will be by gravity along extension can hook seat 4
To downslide, so that the lower hanging groove of dustbin 9 be made to be engaged with lower draw-bar 8;Preferably, lower draw-bar 8 includes: guiding surface and hook groove;
The length of guiding surface is greater than hook groove depth.When the lower lifting lug of dustbin 9 is slided along extension can hook seat 4, by gravity rubbish
The lower lifting lug of bucket 9 will be embedded in lower draw-bar 8 along guiding surface, so that the lower lifting lug of dustbin 9 be made more smoothly to sting with lower draw-bar 8
It closes.
Compression type garbage truck butt buster structure provided by the embodiment of the utility model drives size link arm to realize by oil cylinder
The turning operation of dustbin;By the fixation procedure of the structural design optimization dustbin of upper and lower hooks, to make entire dustbin
Switching process is smooth.Compression type garbage truck butt buster structure structure provided in this embodiment is simple, efficiently convenient;Turning operation simultaneously
It can be completed in lesser space, be very suitable for compression type garbage truck;Simultaneously in view of its production cost of its simple structure
And advantage of lower cost is matched, with being suitble to the assembly of compression type garbage truck to use.
It is arranged by the adjustment of Dalian lever arm 2 and dependency structure, keeps stress more reasonable, use is more convenient, the quality longevity
It orders longer., on the one hand can be with loss of weight by adjusting the setting in hole, it on the other hand can be by the way that adjusting hole be replaced pivot machine
Structure hole uses, adjustable distance, the matching for different size of being more convenient for.
