Detailed description of the invention
The invention will be further described below in conjunction with the accompanying drawings:
As depicted in figs. 1 and 2, the present invention uses hydraulic cylinder to control small scraper pan and automatically loads the tipping bucket of article
Car, including bottom equipped with the car body 1 of road wheel and big scraper bowl 14, the bottom of big scraper bowl 14 is provided with and is fixed on
Dead buting iron 6 on car body 1, to limit the slewing area of big scraper bowl 14.The front end of big scraper bowl 14 is provided with little
Scraper bowl 13, small scraper pan 13 bar 10 outer with expansion link is hinged, is cased with stretching in the other end of the outer bar 10 of expansion link
Bar 8 in contracting bar, in expansion link, the other end of bar 8 is hinged with the fixed block 7 being fixed on car body, expansion link
Between interior bar 8 and the outer bar 10 of expansion link, the first hydraulic cylinder 9 is installed；The middle part of the outer bar 10 of expansion link is fixed
Having head rod 11, head rod 11 bar 15 outer with shrinking connecting-rod is by the second fraising 12 formation hinge
Connect, bar 17 in the other end socket shrinking connecting-rod of the outer bar 15 of shrinking connecting-rod, and be provided with electromagnetic locking device 16,
The collapsing length that can be made the outer bar 15 of shrinking connecting-rod and bar in shrinking connecting-rod 17 by electromagnetic locking device 16 is locked
Fixed；In shrinking connecting-rod, the other end of bar 17 and driving lever 4 are hinged by the first fraising 5 formation, driving lever
The other end of 4 is fixing with the connecting shaft 19 being arranged on rear side of big scraper bowl 14 to be connected, and connecting shaft 19 passes through the
One bearing 20 and the 3rd bearing 24 are arranged on car body, and the middle part of connecting shaft 19 is provided with second and fixes tooth
Wheel 23, the second fixed gear 23 is meshed with the first fixed gear 22, and the first fixed gear 22 is arranged on
From the motor shaft 3 that motor 2 stretches out, motor shaft 3 is connected with car body 1 by the second bearing 21；Described
On the outer bar 10 of expansion link, the second hydraulic cylinder 30 (as shown in Figure 3), the pedestal of the second hydraulic cylinder 30 are installed
Being formed hinged by the 6th fraising 31 in the middle part of bar 10 outer with expansion link, the push rod of the second hydraulic cylinder 30 is simultaneously
Hinged by the 4th fraising 27 formation with the second connecting rod 26 and the 3rd connecting rod 28, the 3rd connecting rod 28
The top of bar 10 outer with expansion link is hinged by the 5th fraising 29 formation, the second connecting rod 26 and small scraper pan
13 is hinged by the 3rd fraising 25 formation, promotes the second connecting rod 26 by the second hydraulic cylinder 30, can make
Small scraper pan 13 rotates around the pin joint of the outer bar 10 of itself and expansion link.
The lateral symmetry of big scraper bowl 14 of the present invention arranges all rod members being connected with connecting shaft 19.
The rod member being connected with connecting shaft 19 of the present invention can only be arranged in the side of big scraper bowl 14, also
Can arrange in the lateral symmetry of big scraper bowl 14, in order to make rod member uniform force, it is easy to control, in both sides
It is symmetrical arranged preferably.
Second hydraulic cylinder 30 of the present invention, it would however also be possible to employ the mechanism of electric pushrod etc replaces.
The operation principle of the present invention is as follows:
1, motor 2 drive motor axle 3 rotates, and the first fixed gear 22 on motor shaft 3 drives therewith
The second fixed gear 23 nibbling sum rotates, and the second fixed gear 23 drives connecting shaft 19 to rotate, connecting shaft
19 drive driving lever 4 to rotate around it, and driving lever 4 is by shrinking connecting-rod outer bar 15, shrinking connecting-rod
Interior bar 17 and head rod 11 pass motion to the outer bar 10 of expansion link, make the outer bar 10 of expansion link drive
Small scraper pan 13 pin joint between bar 8 and fixed block 7 in expansion link rotates, it is achieved small scraper pan 13 is made
Rise or fall motion.
2, the rod member being connected due to bar 10 outer with expansion link can stretch along with expansion link outer bar 10 motion,
Therefore the length of this rod member needs to change, and this rod member is set to telescopic fashion by the present invention, i.e. by stretching
The outer bar 15 of contracting connecting rod is constituted with bar in shrinking connecting-rod 17, when the outer bar 15 of shrinking connecting-rod is stretched to the longest position
(this position is that the outer bar 10 of expansion link stretches to suitable operating position), electromagnetic locking device 16 can be locked
Tight the most flexible.
3, outer for expansion link bar 10 can be released elongation by the first hydraulic cylinder 9, drives small scraper pan 13 to do straight line fortune
Dynamic.
4, the flexible of the second hydraulic cylinder 30 can promote the second connecting rod 26 to move so that it is drives small scraper pan 13
Pin joint around the outer bar 10 of small scraper pan 13 and expansion link rotates, and when the second hydraulic cylinder 30 quits work,
Small scraper pan 13 is lockable；The effect of the 3rd connecting rod 28 is that the second hydraulic cylinder 30 is strutted downwards certain angle
Degree.
5, small scraper pan 13 shovels the process of article and is: first, small scraper pan 13 is released super by the first hydraulic cylinder 9
The height of excessive scraper bowl 14, the outer bar 15 of shrinking connecting-rod extends the most therewith, and the first hydraulic cylinder 9 stops promoting
Time, open electromagnetic locking device 16 and make it the most flexible outer for expansion link bar 15 locking；Then, motor 2
Controlling small scraper pan 13 and downwardly turn over general to ground level position, the second hydraulic cylinder 30 accurately controls scuppit
The side of bucket 13 is concordant with ground, enters small scraper pan 13 to front shovel article by Herba Plantaginis, by electric after having shoveled
Small scraper pan 13 is given rise to higher than big scraper bowl 14 upper surface and close to the position of big scraper bowl 14 by machine 2,
Utilize the second hydraulic cylinder 30 to control small scraper pan 13 side during small scraper pan 13 rotating lifting to protect with ground
Water holding is put down, and prevents article from dropping；Then the second hydraulic cylinder 30 controls small scraper pan 13 and continues rotation, by thing
Product are poured in big scraper bowl 14；Till so repeatedly being filled by big scraper bowl 14, finally close electromagnetic locking device
16 and start the first hydraulic cylinder 9 small scraper pan 13 is regained.
