Description
Technical field
The invention belongs to engineering machinery and mining machinery technical field, be specifically related to a kind of synchronous transmission gear formula working device of loader.
Background technology
The applied equipment of loader mostly is reversal six-connecting-rod mechanism both at home and abroad at present, formed by swing arm, boom cylinder, pull bar, rocking arm and rocking arm oil cylinder, after scraper bowl shovel material finishes; rocking arm oil cylinder pushing rocking arm drives pull bar the scraper bowl end is risen; when then the boom cylinder piston rod extends; must cooperate the elongation of rocking arm cylinder piston rod that scraper bowl is lifted, just can make scraper bowl keep holding level with both hands state; In addition, when promoting the discharge height of scraper bowl by the size that increases rocking arm oil cylinder and swing arm, rocking arm seat beam pin joint must be determined that by " trial and error procedure " this makes troubles for lifting discharge height and unloading distance.
Summary of the invention
The purpose of this invention is to provide a kind of synchronous transmission gear formula working device of loader, can effectively overcome the shortcoming that prior art exists.
The present invention is achieved in that and is illustrated in figure 1 as synchronous transmission gear formula loader structure diagram, includes car body, wheel, power drive mechanism and equipment.The architectural feature of its equipment is an end of swing arm 9 is installed in car body 1 upper forepart by mandrel 3 the first fixed point A place, the 8th fixed point H of the other end of swing arm 9 and scraper bowl 8 bottoms is hinged, the second fixed point B place on the bottom of boom cylinder 10 and the car body 1 is hinged, the 3rd fixed point C place on the top of piston rod and the swing arm 9 is hinged, the first gear 2 is installed on the mandrel 3, the second gear 4 that is meshed with the first gear 2 is installed in the 4th fixed point D place of swing arm 9 by central axis, the 3rd gear 5 that is meshed with the second gear 4 is installed in the 5th fixed point E place on the swing arm 9 by central axis, the 6th fixed point F place on one end of connecting rod 7 and the 3rd gear 5 sides is hinged, the 7th fixed point G place on the other end and scraper bowl 8 tops is hinged, suppose the 5th fixed point E and the 6th fixed point F are connected to form rocking arm 6, designing requirement the 5th fixed point E, the 6th fixed point F, the line of the 7th fixed point G and the 8th fixed point H consists of parallel four-bar linkage, requires simultaneously the modulus of the first gear 2 and the 3rd gear 5, the number of teeth is identical.
Advantage of the present invention and good effect:
(1) the present invention does not need Z-type rocking arm of the prior art and rocking arm cylinder apparatus, by locking and the rotation of the first gear 2, is cooperating elongation and the shortening of boom cylinder 10 piston rods, just can realize shovel material, end material, act material and the discharging state of scraper bowl;
(2) the present invention owing to the planet circular system of three gears formations and in conjunction with parallel four-bar linkage, has guaranteed no matter boom cylinder 10 piston rods extend or indentation, and scraper bowl can both remain holds state level with both hands when the first gear 2 locking;
(3) the present invention is not subjected to the constraint of scraper bowl lifting process rocking arm cylinder sizes restriction, can promote by the length that increases respectively length of connecting rod in the parallel four-bar linkage and swing arm discharge height and the unloading distance of scraper bowl.

The specific embodiment
Shown in Fig. 2-5, with the first gear 2 lockings, boom cylinder 10 keeps locking, makes swing arm 9 motionless with scraper bowl 8 relative car bodies, and loader car body 1 is walked forward, and scraper bowl 8 is realized state of charge, as shown in Figure 2.Keep boom cylinder 10 lockings, then driving counterclockwise the first gear 2 rotates to an angle around mandrel 3, the 3rd gear 5 is owing to the meshing relation between three gears also is rotated counterclockwise, the rocking arm 6 that is positioned on the 3rd gear 5 also just and then is rotated counterclockwise, pulling connecting rod 7 is so that the parallelogram lindage counter-clockwise swing, scraper bowl 8 is realized end material state, as shown in Figure 3.With the first gear 2 lockings, the elongation of boom cylinder 10 piston rods, swing arm 9 is with in the scraper bowl 8 lifting processes, the first gear 2, the second gear 4 and the 3rd gear 5 form planet circular system, then 5 of the 3rd gears center on 2 revolution of the first gear and do not carry out rotation, so rocking bar 6 remains unchanged with the ground angle, then the line of the 7th fixed point G on the scraper bowl and the 8th fixed point H and the angle on ground also remain unchanged, scraper bowl 8 realizes lifting the material process remaining to hold level with both hands under the state, as shown in Figure 4.Boom cylinder 10 lockings drive clockwise the first gear 2 and turn an angle, and drive parallel four-bar linkage and swing clockwise, and scraper bowl 8 is realized discharge process, as shown in Figure 5.Drive clockwise the first gear 2 and turn an angle, scraper bowl 8 is in the process of shovel material position, cooperate the indentation of boom cylinder 10 piston rods, state when scraper bowl 8 realizes getting back to the shovel material.
