Abstract
A positive and negative bucket device relates to an excavator bucket and a connecting rod and solves the problems of high cost and inconvenient operation of the used equipment. Based on the prior excavator components, sloping blocks and connecting ears are added to the bucket device; a rectangular groove is lengthways formed on the middle section of the upper end face of the bucket; two trapezoidal grooves are respectively formed on the left and the right sides of the bucket; the sloping blocks are arranged in the trapezoidal grooves; a pair of connecting ears is arranged on the sloping blocks; the sloping blocks are movably connected with the bucket through pins; the connecting ears of the sloping blocks on the bucket are movably connected with a dipper through pins; a conversion connecting rod joint comprises an upper section and a lower section; cylindrical bosses vertical to axes are formed on both the upper section and the lower section; blind holes are formed on the bosses; shafts are arranged in the blind holes; a boss movably matched with the groove at the upper end of the lower-section boss is formed at the lower end of the upper-section boss; a pin hole vertical to the axes is formed at the lower-section boss; the lower section is movably connected with the upper section through pins via the shafts; and the conversion connecting rod joint rotates by 180 degrees clockwise or anticlockwise.
Description
Technical field
The utility model relates to excavator, relates in particular to power shovel and connecting rod.

At present, the modes such as backacter and loader scarfing cinder that adopt are constructed more in special place construction such as engineering tunnel, foundation ditch, rescue and relief work, municipal narrow environment, need positive backhoe operation simultaneously in some narrow and small special construction places, two kinds of common job executions of equipment be must use, difficulty of construction and equipment use cost increased.Existing scraper bowl device comprises engaging lug, scraper bowl, connecting rod, bucket cylinder and dipper, bucket cylinder one end is connected with dipper, and an end is connected with dipper with scraper bowl by connecting rod, and the deficiency that this scraper bowl device exists is: 1, increased equipment, difficulty of construction is big, the cost height of use; 2, inconvenient operation.
The utility model content
The utility model at the deficiency of above-mentioned existence provide a kind of can not only backhoe excavating, and positive back-hoe bucket device that can also the crowd shovel scarfing cinder.
Technical solutions of the utility model comprise engaging lug, scraper bowl, connecting rod, bucket cylinder and dipper, it is characterized in that also comprising skewback and conversion linkage connector, there is rectangular channel described scraper bowl upper surface in the middle section longitudinally, rectangular channel has the engaging lug of a pair of symmetry and conversion linkage connector to flexibly connect outward, the left side of scraper bowl upper surface, right both sides have a dovetail groove respectively, in this groove skewback is housed, the engaging lug that a pair of symmetry is arranged on the skewback, engaging lug is fixedlyed connected with skewback, skewback and scraper bowl flexibly connect with pin, the engaging lug of skewback and dipper flexibly connect with pin on the scraper bowl, conversion linkage connector upper end flexibly connects with bucket cylinder, lower end and stage casing, scraper bowl the upper surface engaging lug of a pair of symmetry longitudinally flexibly connect with pin, the conversion linkage connector is by last, hypomere constitutes, cylindrical end tangs with the epimere axis normal is arranged at the bottom of epimere, this boss has blind hole, axle is arranged in the blind hole, there is the movable boss that cooperates of groove with conversion linkage connector hypomere upper end the lower end of this boss, the top of hypomere has and the perpendicular boss of hypomere axis, this boss has blind hole, there is the movable groove that cooperates of lower end boss with conversion linkage connector epimere the upper end of boss, the boss of hypomere has the pin-and-hole perpendicular with axis, the upper end of hypomere and the lower end of epimere flexibly connect with pin by axle, and the conversion linkage connector is by turnback clockwise or counterclockwise.
The utility model compared with prior art, its technique effect is:
1, improves scraper bowl and conversion linkage connector, realized scraper bowl positive and reverse steering 180 degree.
2, improved scraper bowl and conversion linkage connector, a table apparatus can be realized two kinds of functions, has reduced use cost.
3, improved scraper bowl and conversion linkage connector, more convenient operation has improved operating efficiency.
