Axially bored line, which is rotated, relative to traditional power shovel technology, in the present invention connects what pin axis were formed with journal stirrup
Plane blow vertically with inwall inclined-plane of the scraper bowl bucket body away from journal stirrup connecting pin, and rotate axially bored line overlapped with two plane intersection lines；This
Sample design main function be so that curved track is small around the radius that rotational pin rotates, increase scraper bowl bucket body wall strength and stability；
Rotational pin is opened on the scraper bowl bucket body wall of installation teeth so that scraper bowl bucket body rotates when cutting the earth relative to rotational pin so that shovel
The scraper bowl bucket body wall that tooth can install teeth on ground, scraper bowl bucket body will not be by the pressure from soil layer, and teeth is only
Scraper bowl can be effectively protected by the active force perpendicular to ground, and scraper bowl can be made to be born bigger when cutting the earth
Power；The effect of fluid torque-converter is deceleration bending moment, when scraper bowl bucket body, which is dug, arrives harder thing, reduces rotating speed, high torque, makes
Obtaining scraper bowl bucket body can be cut the earth with bigger power；The effect of trigger-type expansion plate is, when the arc shell in curved track storehouse is
The second travelling gear turns to during being moved out under the driving of two travelling gears, during this contacts with touch switch
When, trigger-type expansion plate will be stretched out, and withstand next arc shell so that next arc shell can not be swung, and can make second
Travelling gear passes through the gap between two arc shells；The effect of block is to block adjacent arc shell, and arc shell can not be swung,
Arc shell is allowd to form curved track；The effect of curved track storehouse is the arc shell that storage is not driven by the second travelling gear, to prevent
Only when scraper bowl bucket body is cut the earth, arc shell influences scraper bowl bucket body and cut the earth；Drive sleeve is arranged on hydraulic motor temperature of inner ring during rotation, and the 3rd
Travelling gear is arranged in drive sleeve, and the 3rd travelling gear and the engagement of the first travelling gear, the second travelling gear and curved track are nibbled
Close, hydraulic motor provides power and curved track is moved, and drives scraper bowl bucket body to be rotated relative to rotational pin, and scraper bowl bucket body is cut the earth；
The effect of curved track is to transmit hydraulic motor power so that scraper bowl bucket body rotates relative to rotational pin, carries out digging；By
The effect of pressing plate and triggering block is so that when scraper bowl shovel is native, when teeth is not perpendicular to ground, influences liquid by triggering block
Pressure motor rotates so that the teeth of scraper bowl can carry out shoveling native operation perpendicular to ground；(the first back-moving spring and second resets bullet
The effect of spring is, when compression plate is under pressure mobile, the first flexible rack and the second flexible rack will not be caused to interfere；Peace
The effect of full plate is whether identification teeth is perpendicular to shoveling ground；The effect of compression plate is to cut the earth and be not orthogonal to when bucket bucket body
During ground, the guard plate on teeth will be under pressure effect, so that guard plate will be slided on teeth outer wall
Dynamic, the now motion of guard plate is passed on compression plate, so that the first flexible rack and the second flexible rack motion,
The flexible rack of the first of motion and the second flexible rack will give one pressure of stressed plate to act on, due to teeth out of plumb now
In ground, so the teeth outer wall for having side will contact with ground, now compression plate will give one active force of teeth wall, from
And have the function that to strengthen teeth intensity；The effect that oil circuit coordinates between first hydraulic cylinder and second hydraulic cylinder is, mobile bar
Movement pass on slipping block, pass through the sliding of slipping block so that corresponding oil-out and flowline coordinate, to control hydraulic pressure
Motor rotates and reverse.
In use, when carrying out shoveling native operation using equipment of the present invention, teeth enters perpendicular to native surface
In soil, excavator hydraulic system driving hydraulic motor work, the rotation of fluid motor-driven drive sleeve, the transmission of drive sleeve drive the 3rd
Pinion rotation, the 3rd travelling gear drive the first travelling gear to rotate, and the first travelling gear drives the second travelling gear to rotate, the
Two travelling gears drive curved track movement so that curved track drives scraper bowl bucket body to turn relative to rotational pin by journal stirrup connecting pin
Dynamic, scraper bowl bucket body now starts to cut the earth, and when scraper bowl bucket body is gone to parallel to ground, hydraulic motor stops operating, scraper bowl
Bucket body, which is cut the earth, to be terminated；When the second travelling gear drives curved track movement, the second travelling gear drives arc shell to move first, with
The second travelling gear to rotate, the touch switch contact on the second driving cog and arc shell so that trigger-type expansion plate stretches out
And withstand next arc shell；Second travelling gear enters next arc shell by trigger-type expansion plate；Second gear continues
Rotate so that arc shell out forms curved track from curved track storehouse so that the second travelling gear and curved track engagement, drive arc
Shape rail moves；When teeth is without shovel soil perpendicular to the ground, and scraper bowl bucket body is to away from excavator operating personnel inclination；Guard plate by
Active force to soil will move along bar-shaped trough, and the guard plate of motion will drive contiguous block mounted thereto to move, connection
Block will promote the 3rd rack to move；3rd rack will drive the second ratchet to move, and the second ratchet will drive
First gear is moved, and first gear will drive fixing axle to move, and fixing axle will drive second gear, the 3rd gear movement,
Second gear will drive the second flexible rack motion, and the second flexible rack of motion will give compression plate one pressure effect,
So that compression plate will be reinforced to teeth so that teeth can bear the bigger active force of soil；The second of motion stretches
Contracting rack will drive mobile bar to move；Compress (the first back-moving spring and drive mobile bar transverse shifting, compress first hydraulic cylinder, the
One hydraulic cylinder drives second hydraulic cylinder to stretch by flexible pipe, promotes slipping block movement so that the first oil-out and the first flowline
Connect, the 3rd oil-out and the 3rd flowline are connected, and the hydraulic oil of hydraulic oil storage intracavitary is by flexible pipe, by the first flowline
Into hydraulic motor, driving hydraulic motor rotates so that scraper bowl bucket body rotates, and teeth is shoveled soil perpendicular to ground；Work as shovel
Tooth is without shovel soil perpendicular to the ground, and scraper bowl bucket body close to excavator operating personnel to when tilting；Active force of the guard plate by soil
It will be moved along bar-shaped trough, the guard plate of motion will drive contiguous block mounted thereto to move, and motion is so as to the company of that
The 4th rack, the first ratchet, the 3rd gear, second gear, first gear, the first expansion teeth will be driven successively by connecing block
Bar, the second flexible rack；The flexible rack of the first of motion, the second flexible rack will drive mobile bar to move；The movement of motion
Bar will cause first hydraulic cylinder to stretch, and first hydraulic cylinder drives second hydraulic cylinder to stretch by flexible pipe, promote slipping block movement,
So that the second oil-out and the second flowline are connected, the 4th oil-out and the 4th flowline are connected, and hydraulic oil stores the liquid of intracavitary
Force feed passes through flexible pipe, enters hydraulic motor, driving hydraulic motor reversion so that scraper bowl bucket body rotates, and makes by the second flowline
Teeth can shovel soil perpendicular to ground；When teeth is perpendicular to ground, guard plate will not move, and scraper bowl may proceed to shovel soil；Work as shovel
Bucket bucket body is filled when start native after soil, hydraulic motor reversion so that curved track moves along the direction opposite with when shoveling native
Dynamic, scraper bowl bucket body is rotated relative to rotational pin so that soil is poured out out of scraper bowl bucket body.
