But existing trenching machine is not all resolved a pair of outstanding contradiction: the degree of depth of digging pit of existing trenching machine depends on the stroke of drilling rod, and the stroke of drilling rod depends on the piston rod stroke of the hydraulic cylinder of equivalent stroke.Because the piston rod of trenching machine hydraulic cylinder is upright the setting, if the piston rod stroke of hydraulic cylinder is more big, then the height of trenching machine is just more high, and this can bring a lot of difficult problems, as be difficult to guarantee the balance quality of trenching machine, be difficult to guarantee the axiality of piston rod, drilling rod; If the piston rod stroke of hydraulic cylinder is more short, the depth as shallow of then digging pit is difficult to satisfy actual requirement again.
Three, summary of the invention
The purpose of this utility model is to overcome the deficiencies in the prior art, designs a kind of easy making, and cost is low, and efficiency of construction height, the stroke of drilling rod are two times multifunction traction formula trench excavators of the piston rod stroke of hydraulic cylinder.
Basic ideas of the present utility model are to utilize the characteristics of movable pulley: namely use movable pulley can economize half power, take distance.Because when using movable pulley, the hook sign indicating number is played by two sections ropes, every section rope is only born half of hook code weight.Though use movable pulley to economize power, the distance that power moves is 2 times of the distance that raises of hook sign indicating number, has namely taken distance.Can not change the direction of power.Move along with the movement of object.Only " the hook sign indicating number " in the utility model is piston rod (also being movable pulley simultaneously), and " distance that power moves " is the distance that drilling rod moves, i.e. the reverse characteristics of utilizing movable pulley.
The technical solution of the utility model is: a kind of multifunction traction formula trench excavator, comprise frame, be fixed in the two-way hydraulic cylinder on the frame, two-way hydraulic cylinder is connected with hydraulic means with hydraulic control lever by hydraulic oil pipe, and the piston rod in the two-way hydraulic cylinder is upwards upright; Be fixed in the reducer on the frame, the drilling rod that cooperates with reducer output shaft, the actuating unit that cooperates with reducer input shaft, the tool joint that is connected with drilling rod, the spiral driving device that is connected with tool joint, be connected in the pushing mechanism between piston rod and the drilling rod, it is characterized in that pushing mechanism comprises:
Be fixed on the holder on the frame, the fixed seating is in a side of piston rod, and drilling rod is positioned at the opposite side of piston rod, and namely holder and drilling rod lay respectively at the piston rod left and right sides;
Two-way hydraulic cylinder outer wall upper edge is axially arranged with guide rail, i.e. the hydraulic cylinder double slideway of doing following travelling carriage simultaneously;
Be provided with the travelling carriage that is constituted by many connecting rods, cochain wheel seat, lower sprocket seat;
Travelling carriage top is fixed on the piston rod top, and the bottom is sleeved on the guide rail, like this, travelling carriage just along slideway with the same moved further of piston rod;
On the cochain wheel seat sprocket wheel is housed, is with zip strip on the sprocket wheel, an end of last zip strip is fixed on the holder, and the other end of last zip strip is fixed on the drilling rod top; And when piston rod rising H, the travelling carriage H that rises synchronously, last zip strip pulling drilling rod rising 2H, following zip strip did not down stress and only dallied with sprocket wheel this moment;
On the lower sprocket seat sprocket wheel is housed, be with down zip strip on the sprocket wheel, one end of following zip strip is fixed on the holder, the other end of following zip strip is fixed on the drilling rod top, and when piston rod decline H, the travelling carriage H that descends synchronously, following zip strip pulling drilling rod decline 2H, zip strip does not stress and only dallies with sprocket wheel on this moment.
Further scheme is: travelling carriage is provided with two and puts chain pulley seat and last zip strip, and two cover lower sprocket seats and following zip strip are with mechanical performances such as the balance that guarantees pushing mechanism, stability, the transmission of increase power.
This multifunction traction formula trench excavator can be easily and the supporting suspensions of actuating unit such as tractor with small four wheels, agricultural vehicle, wheel excavator, crawler-mounted excavator, and utilize the hydraulic means (system) of above-mentioned vehicle and equipment simultaneously.
The utility model has the advantages that: the stroke of both having realized drilling rod is two times of piston rod stroke of hydraulic cylinder, can guarantee the balance quality of trenching machine again, guarantees the axiality of piston rod, drilling rod, satisfies the requirement of the degree of depth of digging pit; Make easily, cost is low, the efficiency of construction height.Be be applicable to plant trees, urban construction, road construction, booth construction or other the multi-functional construction machinery that need dig pit in the soil.
This trench excavator can form with the farm tractor transformation of the way, and its frame is connected with hanging and supporting device behind the tractor.The time spent can not be divided into the use that two separate components do not influence tractor, and is convenient to disassembly.
This trench excavator power transmission is generally the sprocket wheel chain drive, and it has characteristics such as the power laser propagation effect is good non-slip than belt transmissioning mode.
The general mode that adopts six square bars and interior six sides cover to combine of this trench excavator drilling rod makes it strengthen intensity and the lifting flexibly of drilling rod and drill bushing.
The lifting gear of this trench excavator is travelling carriage, thereby can be operated the speed of its lifting and exerted all one's strength downwards to it by hydraulic cylinder in digging pit and can accelerate excavation speed by hydraulic control lever.
This trench excavator reducer side direction driving cog can be special-purpose basin tooth and angle tooth, makes its transmission intensity be superior to general Bevel Gear Transmission greatly.
The spiral of this trench excavator driving device (drill bit) be dismountable, can be quickly and easily the size of bit change more, the diameter that change is digged pit, and be beneficial to the maintenance of drill bit.
