Description
Technical field
The present invention 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 cubic metre of earth and stone construction equipment in the engineering machinery field; Be widely used in 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, and the enormous impact power that heavy load produced that particularly increases suddenly can cause very big 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 powerless.In addition; The tradition excavator is when carrying out digging operation to more closely knit soil of this type such as the 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; Have certain limitation, scraper bowl and soil contact site also usually can run into situation such as excavating resistance is big, scraper bowl insertion difficulty during excavation; Thereby cause additive decrementation, the reduction digging efficiency of power set; Increase task difficulty, can cause the scraper bowl wearing and tearing to accelerate problems such as excavate costs raising simultaneously.
Summary of the invention
The technical problem that the present invention will solve is to overcome disadvantages of 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 present invention includes scraper bowl, the scraper bowl back side is provided with first bearing and second bearing; First bearing and dipper front end are hinged; Second bearing is fixedly connected with connecting rod, and connecting rod is hinged through bearing pin and bucket cylinder one end, and two sidewalls of dipper are provided with eccentric shaft free to rotate; Eccentric shaft is connected with the power set that can drive the eccentric shaft rotation, and power set are arranged on the dipper; Said 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 invention have advantage to be; Scraper bowl cuts soil with the mode that continuous shaking is impacted, and can impel the loosening rapidly or broken fracture of soil, improves the excavation speed of excavator; Improve the environmental suitability of excavator in special region; Prolong the application life of excavator, have better economic property, also practiced thrift the energy.

The specific embodiment
Below in conjunction with accompanying drawing the present invention is done further explanation.
As shown in Figure 1, the present invention includes scraper bowl 1, scraper bowl 1 back side is provided with first bearing 2 and second bearing 3; First bearing 2 is hinged with dipper 4 front ends; Second bearing 3 is fixedly connected with connecting rod 5, and connecting rod 5 is hinged through bearing pin 6 and bucket cylinder 7 one ends, and 4 two sidewalls of dipper are provided with eccentric shaft free to rotate 8; 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; Said 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 5, rocking arm 10 is realized with being fixedly connected through 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, excessive gear 16, driven gear 15 and hydraulic motor 17.As shown in Figure 3, hydraulic motor 17 is fixedly connected with driving shaft 12 through shaft coupling 11.Driving shaft 12 and driving gear 13 are fixedly connected through flat key.Driving shaft 12 passes through bearing fixing on dipper 4.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 through 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 through flat key.Eccentric shaft 8 passes through bearing fixing on dipper 4.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 through the different axle center of interlude with two ends.Rocking arm 10 stretching motion drivening rods 5 move reciprocatingly.Thereby driving scraper bowl 1 is the center of circle with first bearing 2 with dipper 4 hinged pin joints, carries out curved surface and moves back and forth.Excessively the connected mode between gear 16 and the dipper 4 is as shown in Figure 4, connects through bearing fixing.
