The middle part of the fixed connector is arranged with holes connected with the moveable lock-tongue and the control cylinder. The front part of the fixed connector is arranged with a working arc connected with the working equipment. A hook is hoisted above the fixed connector. The rear of the moveable lock-tongue is connected to the fixed connector through the lock-tongue pin and the shaft sleeve and can rotates around the lock-tongue pin. An oil cup is arranged on the moveable lock-tongue. The middle part of the lock-tongue is provided with a hole connected with the control cylinder. The control cylinder is respectively hinged with the fixed connector through the oil cylinder rear pin and the oil cylinder front pin. The oil control pipe of the control cylinder is connected with the bucket rod of the excavator through double-direction hydraulic lock. The utility model which is convenient to operate, safe and reliable, can replace different working equipment rapidly and thus increasing the working efficiency.

Description

The work implements fast replacing device of a kind of small type hydraulic excavator and loader-digger

Technical field the utility model belongs to the work implements fast replacing device technical field of excavator, the work implements fast replacing device of particularly a kind of suitable small type hydraulic excavator and loader-digger.

Background technology is present, small type hydraulic excavator and loader-digger exist as a kind of middle-size and small-size special mechanical kind, collect multiple functions such as shovel dress, excavation, soil-shifting, fragmentation in a machine, be a kind ofly be widely used, site operation machinery that compliance is stronger, be widely used in complexity, scrappy object of construction production.Need the different work implements of frequent replacing to adapt to the needs of workplace practical operation in work progress, traditional method is to pull down two bearing pins, changes required facility, and then two bearing pins are loaded onto.This method not only bothers, and wastes time and energy, and particularly the working site dust is bigger, causes the lubricant housings to pollute easily, reduces the application life of hinge point.

The summary of the invention the purpose of this utility model provides a kind of work implements fast replacing device of changing simple and efficient small type hydraulic excavator and loader-digger, to solve the on-the-spot problem of changing difficulty of work implements.

The utility model has been taked following technical scheme: the work implements fast replacing device of the utility model small type hydraulic excavator and loader-digger, comprise rigid connector, movable dead bolt, control oil cylinder, control oil pipe and bidirectional hydraulic lock, it is characterized in that: admittedly be connector by vertical side plate with laterally be connected the steel pipe frame construction that is welded, its rear side is provided with the hole that is connected with pull bar with excavator boom, the centre is provided with the hole that is connected with movable dead bolt and control oil cylinder, there is the work circular arc that is connected with work implements the front side, is provided with the suspension hook of lifting usefulness above it; Movable dead bolt is by vertical side plate and the horizontal steel pipe frame construction that is welded that is connected, the rear portion is connected on the rigid connector by dead bolt bearing pin and axle sleeve, and can on the movable dead bolt lubricating cup be installed around the rotation of dead bolt bearing pin, there is the hole that is connected with the control oil cylinder at the dead bolt middle part; The control oil cylinder is a two-way cylinder, is hinged with rigid connector respectively by bearing pin before oil cylinder rear pin shaft and the oil cylinder, and the control oil pipe of control oil cylinder is connected with the dipper of excavator by bidirectional hydraulic lock.

The work implements fast replacing device of the utility model small type hydraulic excavator and loader-digger is connected with oil circuit by bidirectional hydraulic lock, and this control mode has easy to operate, safe and reliable characteristics.The utility model has carried out brand-new design from simplifying aspects such as changing operation, raising replacing efficient, not only construction profile is attractive in appearance, good manufacturability, and rigidity is big, cost is low, simple to operate, change the different operating facility and only need about one minute, improved operating efficiency greatly.

Appended drawings is the utility model structural representation.

Bearing pin 6, movable dead bolt 7, work circular arc 8, suspension hook 9, lubricating cup 10, axle sleeve 11, dead bolt bearing pin 12, cylinder lever connecting rod hole 13, control oil pipe 14, bidirectional hydraulic lock 15 among the figure 1, before the rigid connector 2, oil cylinder rear pin shaft 3, work circular arc 4, control oil cylinder 5, oil cylinder, connect the dipper hole

The specific embodiment with reference to the accompanying drawings, the work implements fast replacing device of the utility model small type hydraulic excavator and loader-digger, comprise rigid connector 1, movable dead bolt 6, control oil cylinder 4, control oil pipe 13 and bidirectional hydraulic lock 14, movable dead bolt 6 is by dead bolt bearing pin 11, axle sleeve 10 is installed on the rigid connector 1, and can be around 11 rotations of dead bolt bearing pin, lubricating cup 9 is housed on it, control oil cylinder 4 by oil cylinder rear pin shaft 2 and oil cylinder before bearing pin 5 be hinged with rigid connector 1 respectively, control oil pipe 13 links to each other with the machine hydraulic system by bidirectional hydraulic lock 14, and bidirectional hydraulic lock 14 is connected with the dipper of excavator.

The work implements fast replacing device operating principle of the utility model small type hydraulic excavator and loader-digger is as follows: the cylinder lever connecting rod hole 12 at rigid connector 1 rear portion be connected dipper hole 15 and be connected with bearing pin with pull bar with dipper respectively, at first hook dipper bearing pin on the work implements during installation work facility with the work circular arc 3 of rigid connector 1 underside of forward, make the work circular arc 7 of rigid connector 1 anterior upside press close to pull bar bearing pin on the work implements simultaneously, make the big chamber oil-feed of control oil cylinder 4 then, movable dead bolt 6 turns clockwise, and work implements upper connecting rod bearing pin is hooked and utilizes oil cylinder power that work implements upper connecting rod bearing pin is clamped with the work circular arc 7 of rigid connector 1 anterior upside; Make the loculus oil-feed of control oil cylinder 4 when unloading work implements, movable dead bolt 6 is rotated counterclockwise, and the work circular arc 7 of rigid connector 1 anterior upside is open, fast replacing device is broken away from from work implements to get final product again.
