The excavating device further comprises a rocker arm, a through hole matched with the eccentric shaft is arranged at one end of the rocker arm, one end of the rocker arm is fixedly connected with the eccentric shaft, and the other end of the rocker arm is provided with a round hole matched with a pin and hinged with the pin.
Description
Technical field
The utility model relates to the excavating gear of a kind of excavator, particularly a kind of excavator.
Background technology
At present, excavator is a kind of typical restoration in earth-rock construction equipment in the engineering machinery field, be widely used in the fields such as engineering construction, mine excavation, irrigation and water conservancy and defence and military, because excavator operation environment more complicated is abominable, its excavating gear bears load variations in operation process rapid, the enormous impact power that the heavy load that particularly increases suddenly produces can cause very large infringement to excavating gear and machine self structure part, power set etc., when extraneous soil resistance during greater than maximum digging operation power, traditional excavator is with helpless.In addition; the tradition excavator is when carrying out digging operation to more closely knit soil of this class such as geologic structure harder soil layer or the soil that hardens, the concrete soil layer that mixes, the sedendary soil that does not excavate, frozen soil layers; there is certain limitation; scraper bowl and soil contact site; also usually can run into the situations such as excavating resistance is large, scraper bowl insertion difficulty during excavation; thereby cause additive decrementation, the reduction digging efficiency of power set; increase task difficulty; can cause simultaneously the scraper bowl wearing and tearing to accelerate the problems such as excavate costs raising.
Summary of the invention
The technical problems to be solved in the utility model is the deficiency that overcomes background technology, and a kind of excavating gear of excavator is provided, and makes excavator increase a kind of vibrocutting soil function newly, forms special vibration digging operation.
In order to solve the problems of the technologies described above, the utility model comprises scraper bowl, the scraper bowl back side is provided with the first bearing and the second bearing, the first bearing and dipper front end are hinged, the second bearing is fixedly connected with connecting rod, and connecting rod is hinged by bearing pin and bucket cylinder one end, is provided with eccentric shaft free to rotate on two sidewalls of dipper, eccentric shaft is connected with the power set that can drive the eccentric shaft rotation, and power set are arranged on the dipper; Described excavating gear also comprises rocking arm, and rocking arm one end is provided with the perforation with the eccentric shaft coupling, and is fixedly connected with eccentric shaft, and the rocking arm other end is provided with the circular hole with the bearing pin coupling, and hinged with bearing pin.
Of the present utility model have advantage to be, scraper bowl cuts soil in the mode that continuous shaking is impacted, can impel rapidly loosening or broken fracture of soil, improve the excavation speed of excavator, improve excavator at the environmental suitability of special region, prolong the application life of excavator, have preferably economy, also saved the energy.

The specific embodiment
Below in conjunction with accompanying drawing the utility model is described further.
As shown in Figure 1, the utility model comprises scraper bowl 1, scraper bowl 1 back side is provided with the first bearing 2 and the second bearing 3, the first bearing 2 is hinged with dipper 4 front ends, the second bearing 3 is fixedly connected with connecting rod 5, and connecting rod 5 is hinged by bearing pin 6 and bucket cylinder 7 one ends, is provided with eccentric shaft free to rotate 8 on 4 two sidewalls of dipper, eccentric shaft 8 is connected with the power set that can drive eccentric shaft 8 rotations, and power set are arranged on the dipper 4; Described excavating gear also comprises rocking arm 10, and rocking arm 10 1 ends are provided with the perforation with eccentric shaft 8 couplings, and is fixedly connected with eccentric shaft 8.As shown in Figure 4, rocking arm 10 is realized with being fixedly connected with by bearing of eccentric shaft 8.Rocking arm 10 other ends are provided with the circular hole with bearing pin 6 couplings, and hinged with bearing pin 6.
As shown in Figures 2 and 3, power set comprise driving gear 13, excessively gear 16 driven gears 15 and hydraulic motor 17.As shown in Figure 3, hydraulic motor 17 is fixedly connected with driving shaft 12 by shaft coupling 11.Driving shaft 12 and driving gear 13 are fixedly connected with by flat key.Driving shaft 12 is fixed on the dipper 4 by bearing.Hydraulic motor 17 drives driving shaft 12 and clockwise rotates, and driving shaft 12 drives driving gear 13 and clockwise rotates.As shown in Figure 2, driving gear 13 and excessive gear 16 are connected by straight-tooth.Driving gear 13 clockwise rotates, and drives excessive gear 16 and rotates counterclockwise.Excessive gear 16 rotates counterclockwise drive driven gear 15 and clockwise rotates.As shown in Figure 5, driven gear 15 and eccentric shaft 8 are fixedly connected with by flat key.Eccentric shaft 8 is fixed on the dipper 4 by bearing.As shown in Figure 2, driven gear 15 clockwise rotates the interlude that drives eccentric shaft 8 and moves clockwise, and eccentric shaft 8 makes two ends drive rocking arm 10 at the vertical direction stretching motion by the different axle center of interlude from two ends.Rocking arm 10 stretching motion drivening rods 5 move reciprocatingly.Thereby drive scraper bowl 1 take the hinged pin joint of the first bearing 2 and dipper 4 as the center of circle, carry out curved surface and move back and forth.Excessively the connected mode between gear 16 and the dipper 4 is fixedly connected with by bearing as shown in Figure 4.
