Further describe the invention below in conjunction with embodiment shown in the drawings.
The work system assembling is that the eccentric wheel (3) that both direction is opposite is connected with III axle (1) end that stretches out gearbox body (39) both sides respectively by flat key (2).Then by be contained in bearing (8) and excentric sleeve (10) on the eccentric shaft (5), adorn bearing bearing box (9), withstand on bearing gland (7) on the bearing, be placed on the elastic circlip (6) that withstands in the bearing box groove on the bearing gland, pick arm bearing box that the eccentric shaft (5) that is connected with eccentric wheel is formed is connected with eccentric wheel with nut (4) and tightens together.Again lean on pulley spindle (13) and the pulley (12) that pass the pulley yoke (16) that tightens together with bolt (15) and diesel oil frame (14) are bearing in an end and the welding of pick arm bearing box of the pick arm (11) that swings up and down with eccentric wheel on the pulley yoke inner orbit.Then the pick body and function pin (22) that assembles is connected with the pick arm.
The main assembling situation of steering is that little sleeve end with the tooth rest (37) in the gearbox body (39) is towards the gearbox body inwall, pack into from bottom to top below the pinion (25) that is assemblied in advance on the IV axle (24), the back semiaxis (46) that axle shaft bearing seat (45) then will be installed is entered the little axle sleeve endoporus and back sprocket wheel (31) endoporus of tooth rest by the gearbox body outside, use flat key (30) that back sprocket wheel and back semiaxis are assembled together then, make the little sleeve diameter of tooth rest become glade plane space to cooperate with the back semiaxis, with bolt (44) the axle shaft bearing seat is fixed on the gearbox body, split pin (47) packed into protrude in the outer later half pin hole of back sprocket wheel, the back sprocket wheel is located on the semiaxis of back, thereby also make the steering location.
Forward gear (26) and backward gear (36) all not with the situation of IV axle pinion (25) engagement under, the gear teeth that to operate gear shaft (38) are aimed at the teeth groove on the tooth rest, the manipulation axle head of steerage gear axle is aimed at axle bed (43) hole that has been installed on the gearbox body, release from inside to outside, use flat key (41) and nut (42) to make steerage gear axle and the assembling of control arm (40) axle sleeve at last.
The power transmission principle: with the diesel engine is power, be delivered to clutch (55) by belt pulley (56), drive the triple gear (54) on the I axle (53) in the gearbox body (39), the gear (52) that triple gear drives on the II axle (51) rotates the II axle, the duplicate gear (50) that on the III axle, trackslips by another gear driven on the II axle, drive IV axle gear wheel (48) by the pinion on the duplicate gear, operating parts by output installation on the tooth rest, the manual operation control arm, the gear teeth driven gear frame of steerage gear axle, thereby make pinion (25) engagement on forward gear (26) or backward gear (36) and the IV axle, the realization digging machine advances or retreats.In addition by with tooth rest in transmission gear wheel interlock back sprocket wheel drive chain and be delivered to preceding sprocket wheel, half front axle, reach four wheel drive.
Advance, stop, fall back, turn to by the manipulation arm and realize.
Advance: when control arm is pushed forward to progressive position, the steerage gear clockwise direction rotates an angle, the driven gear frame is the center of circle with the semiaxis, rotate counterclockwise an angle, thereby make forward gear on the transmission gear wheel of interlock in tooth rest and the pinion on the IV axle, realize advancing.
Stop: when motion arm is in the centre position, forward gear on the transmission gear wheel of interlock in tooth rest and backward gear all not with IV axle pinion, cut off power this moment, realize stopping.
Fall back: move to backward when falling back the position when control arm, steerage gear is followed control arm and is counterclockwise rotated an angle, and driven gear frame clockwise direction rotates an angle, thereby makes backward gear and IV axle pinion in the gear, realizes falling back.
Turn to: when one of two control arm are moved to progressive position, when another moves the centre position to, can realize that digging machine slowly turns, when one of control arm is moved to progressive position, another control arm is moved to when falling back the position, can reach digging machine zig zag or cast.
Plane the ground: when moving operation board upper tooth embedding clutch operating handle to binding site, jaw clutch (49) has been embedded in the duplicate gear that trackslips on the III axle, duplicate gear drives jaw clutch and the III axle rotates, eccentric wheel at III axle two ends drives the pick arm, the pulley that is contained on the pick arm pulley spindle does reciprocating linear motion along the pulley track in the pulley yoke on the one hand, when radially rotating up and down, eccentric wheel moves along a curved path on the other hand along the pulley yoke two ends, make the pick body that is connected pick arm front end like this under the condition of the reciprocal curvilinear motion up and down of pick arm, the action that imitation is manually planed the ground is constantly cut the soil layer plane and is carried out work with loosening the soil.Produce counter pull simultaneously, impel digging machine forward, thereby reduced the consumption of driving force, improved the operating rate of digging machine.
