Among Fig. 2～Fig. 4: inclination scraper bowl (1), bolt (2), oil cylinder bearing pin I (3), dump ram (4), oil cylinder bearing pin II (5), tilting gearing (6) connects bearing pin (7), fast replacing device (8), connecting rod (9), rocking bar (10), bucket cylinder (11), dipper (12).
The specific embodiment
Most preferred embodiment of the present utility model is such, under the prerequisite that the swing arm, dipper, rocking bar, connecting rod, boom cylinder, bucket thick stick oil cylinder, bucket cylinder, the fast replacing device that have type now do not change, increase a tilting gearing (6), an inclination scraper bowl (1), two dump rams (4) and seven bearing pins (3,5).Being equipped with two bearing pins (5) on the tilting gearing (6) can be connected fast with fast replacing device, dismounting.Front end at tilting gearing (6) has one group of hole to be used for connecting with inclination scraper bowl (1), and this group hole can only be rotated around the center, hole by a bearing pin (7) restriction inclination scraper bowl (1); Opposite side at tilting gearing (6) has two groups of holes, and these two groups of holes can only be rotated around the center, hole that inclination scraper bowl (1) is connected with tilting gearing (6) by two bearing pins (3) restriction oil cylinders (4).Inclination scraper bowl (1) except satisfying the performance parameters requirement, also will satisfy intensity instructions for use and appearance requirement when design.Three groups of holes are arranged on inclination scraper bowl (1), and one group of hole is used to tilt being connected of scraper bowl (1) and tilting gearing (6), and two groups of holes are used respectively and being connected with two dump ram (4) in addition.Two dump rams (4) connect by tee junction with oil pipe, the large and small chamber of an oil cylinder connects little, the big chamber hydraulic fluid port of another root oil cylinder, tee junction another excuse connect the oil inlet and outlet of oil feed line respectively, can guarantee that like this an end oil cylinder another root oil cylinder in elongation shrinks, two oil cylinders act on simultaneously, to the thrust of inclination scraper bowl, dump ram (4) can set its locating distance and stroke is provided with the required inclination scraper bowl deflection angle of user when having strengthened deflection.When guaranteeing that bucket tilt is excavated, the oil cylinder of control bucket tilt can not shrink and involuntary maneuvers such as stretching owing to the external force effect produce, so increase the hydraulic lock function on the oil circuit of control tipping bucket oil cylinder.The bucket capacity of inclination scraper bowl (1), bucket shape structure and structural strength etc. can be carried out the differentiation design according to type size, environment for use etc.Rear end at inclination scraper bowl (1) requires five groups of holes of design according to deflection angle, one group of hole connects with connecting the same tilting gearing of bearing pin (7) (6), four groups of holes use two dump rams (4) to connect with two dump rams (4) head earhole respectively by two oil cylinder bearing pin I (3) respectively in addition, two dump rams (4) other end is connected with two groups of holes of tilting gearing (6) by two oil cylinder bearing pin II (5) respectively, the mode that is connected alternately by big chamber of one side oil cylinder and another side oil cylinder loculus, when having realized oil cylinder elongation on one side, the another side oil cylinder shortens, promote inclination scraper bowl (1) and rotate, realized the function that inclination scraper bowl (1) tilts around connecting bearing pin (7).Above-mentioned oil cylinder bearing pin I (3), oil cylinder bearing pin II (5), the diameter that connects bearing pin (7) are by the space of tilting gearing (6), inclination scraper bowl (1) and dump ram (4) and deflection is stressed edits.Have two same fast replacing devices of fixed connection shaft (8) to connect on the tilting gearing (6), fast replacing device (8), connecting rod (9), rocking bar (10), dipper (12), bucket cylinder (11) are finished connection by the bearing pin of correspondence.When adopting this bucket tilt device, the user can be according to working range, maybe needs the shape excavated, regulates the angle of inclination scraper bowl (1) by handling dump ram (4), cooperates with other hydraulic cylinder to fulfil assignment.
