Abstract
The utility model relates to a position rotation six-bar linkage mechanism of a small-sized loading machine, which comprises a front frame, a moving arm, a rocker arm, a shovel, a pull rod, a moving arm cylinder and a rotating hopper cylinder. Linear distances of hinged points among the moving arm, the rocker arm, the shovel, the pull rod, the moving arm cylinder and the rotating hopper cylinder are in reasonable proportion, thereby increasing strength and stability of the moving arm, spatially reasonably arranging components, preventing the rocker arm and the frame from being interfered with each other, leading the loading machine to have larger digging force and faster material digging speed, and guaranteeing better operation property and operation efficiency of the loading machine.
Description
Technical field
The utility model relates to a kind of engineering machinery, is meant a kind of just commentaries on classics six bar mechanism of small sized loader especially.
Background technology
Loader is a kind of high efficiency engineering mechanical device, it is widely used in the shovel in places such as engineering such as highway, railway, harbour, harbour, coal, mine, water conservancy, national defence and urban construction and pretends industry, the main device of loader work is a linkage, is generally counter-rotating six bar mechanism or the parallel six bar mechanism that just changeing.Just change six bar mechanism and mainly comprising front frame, swing arm, rocking arm, scraper bowl, pull bar, boom cylinder and rotary ink tank usually, six bar mechanism is hinged on and carries out operation on the front frame, has the power transmission of ground location scraper bowl digging force than advantage such as big, that the scraper bowl discharge rate is fast; But a major defect that is just changeing six bar mechanism in the prior art is that rotary ink tank and front frame pin joint position are higher, influence the operator visual field during operation, and front frame, swing arm; rocking arm; scraper bowl; pull bar; the laying of each pin joint does not also reach transaction capabilities and efficient preferably between boom cylinder and the rotary ink tank; cause the digging force of scraper bowl less relatively;; then must improve the pressure of hydraulic system or the diameter of increasing rotary ink tank; so can increase the quality of complete machine so in order to increase digging force, particularly more undesirable for a kind of small-sized loader.
The utility model content
The purpose of this utility model is to provide that a kind of digging force is bigger, the lifting translation, set level the just commentaries on classics six bar mechanism of the better small sized loader of effect automatically.
For achieving the above object, technical solution of the present utility model is:
A kind of just commentaries on classics six bar mechanism of small sized loader, it comprises front frame, swing arm, rocking arm, scraper bowl, pull bar, boom cylinder and rotary ink tank; One end and the front frame of described swing arm are hinged, and the bottom of the other end and scraper bowl is hinged; The lower end of described rocking arm is articulated in the pre-position of the close scraper bowl of swing arm front end and constitutes swivel point, and an end of the upper end of rocking arm and pull bar is hinged, and the other end of pull bar is then hinged with the middle part of scraper bowl; One end and the front frame of described boom cylinder are hinged, and the end of its push rod of boom cylinder then is hinged with the middle part of swing arm; One end and the front frame of described rotary ink tank are hinged, and the end of its push rod of rotary ink tank then is hinged with the middle part of rocking arm; ：∶∶∶∶∶∶∶∶∶：1680-1760∶935-985∶252-282∶720-790∶580--630∶264-294∶175-198∶1266-1346∶1069-1139∶490-530。
∶∶∶∶∶∶∶∶∶：1720∶965∶272∶760∶610∶284∶185∶1307∶1099∶510。
After adopting such scheme, because the utility model mainly is to design rational swing arm at small sized loader; rocking arm; scraper bowl; pull bar; the proportionate relationship of several pin joint air line distances between boom cylinder and the rotary ink tank; and the lower end of rocking arm is articulated in the swing arm front end constitutes swivel point; increased the driver visual field near the pre-position of scraper bowl; and because of pin joint relatively near scraper bowl; increased the intensity and the stability of swing arm; and make each member connection and reasonable arrangement in the space; make rocking arm and front frame reach and can not have interference problem; and make that the digging force of loader is bigger; the spading material is faster, has guaranteed that loader has transaction capabilities and preferable operating efficiency preferably.
Below in conjunction with the drawings and specific embodiments the utility model is further described.
Description of drawings
Fig. 1 is a schematic perspective view of the present utility model;
Fig. 2 is an elevation of the present utility model.
The specific embodiment
As shown in Figure 1, 2, be the just commentaries on classics six bar mechanism of a kind of small sized loader of the utility model, it comprises front frame 1, swing arm 2, rocking arm 3, scraper bowl 4, pull bar 5, boom cylinder 6 and rotary ink tank 7.
Each member of the present utility model connects into mechanism by the articulated form of bearing pin, and concrete connected mode is as follows:
One end and the front frame 1 of described swing arm 2 are hinged, and make that pin joint is O, and the bottom of the other end and scraper bowl 4 is hinged, and make that pin joint is G; The lower end of described rocking arm 3 is articulated in the pre-position of the close scraper bowl 4 of swing arm 2 front ends and constitutes swivel point, make that pin joint is D, an end of the upper end of rocking arm 3 and pull bar 5 is hinged, makes that pin joint is B, the other end of pull bar 5 is then hinged with the middle part of scraper bowl 4, makes that pin joint is F; One end and the front frame 1 of described boom cylinder 6 are hinged, and make that pin joint is I, and the end of boom cylinder 6 its push rods then is hinged with the middle part of swing arm 2, make that pin joint is E; One end and the front frame 1 of described rotary ink tank 7 are hinged, and make that pin joint is A, and the end of rotary ink tank 7 its push rods then is hinged with the middle part of rocking arm 3, make that pin joint is C; In addition, the forward terminal of scraper bowl 4 is H.
