Abstract
The utility model discloses a small ditcher. A mini wheel tractor is used as a basic cart. A bracket beam is arranged on the cart. The bracket beam is provided with a gap bridge gearbox and a chain knife type digging mechanism and a hydraulic lifting mechanism. Two power output shafts are led out from the gap bridge gearbox respectively driving the hydraulic mechanism and the digging mechanism. The chain knife of the utility model is assembled with a reeling dragon device for soil discharging out of the ditch at the same time. The width of the chain knife is 150-300 millimeters. The chain knife can be arranged in the middle, or on one side. The ditcher solves the problem of the mechanized construction for digging mini grooves.
Description
The invention belongs to digging machinery and particularly excavate the small-sized trenching machine that width is no more than 300 millimeters.
At present in excavating groove construction, when excavating the groove of width more than 500 millimeters, all realized the mechanization ditching, hydraulic backhoe has been arranged, wheel and bucket ditch dredger, chain bucket excavator or the like.But when excavating the small-sized groove of width below 400 millimeters, also not have suitable excavation machinery, generally still by iron mill, pickax and sledgehammer hand digging.And the small-sized groove of this class is very general in urban water supply, power supply, steam line construction.
The objective of the invention is on the basis that utilizes prior art as far as possible, to replace heavy manpower construction problem with machinery in a kind of small-sized groove construction of small-sized ditching machinery solution that is easy to make of design.
The present invention adopts following mode to realize.The inventor adopts Dongfanghong 20 minitype wheeled tractors as basic car, sets up one pair of rack beams on basic car, installs hydraulicefficiency elevation structure on the rack beams, digging mechanism and a gap bridge gearbox that chain cutter, volume dragon are formed; The gap bridge gearbox is contained between motor and the gear box of tractor, between motor and the gap bridge gearbox and on the final drive shaft between gap bridge gearbox and the locomotive gearbox clutch is being arranged respectively, main shaft one side of gap bridge gearbox is drawn two power output shafts, a power output shaft drives hydraulic pump and connects hydraulicefficiency elevation structure, another power output shaft drive chain cutter and volume dragon.The chain cutter is supported by the chain knife rest, the chain knife rest links with the rack beams rear cross beam is vertical, and volume dragon is parallel with rear cross beam, be positioned at rack beams tail end outside, and the volume dragon spool connects with the chain knife rest by bearing, on the volume dragon axle driven wheel is arranged, roll up imperial driven wheel and connect with the cutter chain engagement of chain cutter; Hydraulicefficiency elevation structure is made up of two hydraulic cylinders and a rocking bar, rocking bar one end is vertical with rear cross beam to link, the other end and the parallel hinge joint of second hydraulic cylinder, the piston rod end of second hydraulic cylinder and the parallel hinge joint of chain knife rest, rocking bar middle part fulcrum links with the first hydraulic cylinder piston rod end parts parallel, and first hydraulic cylinder connects with cylinder frame on the rack beams.The chain cutter width that the present invention adopts can design several specifications between 150～300 millimeters.In hydraulic mechanism, establish an overflow valve in the landing loop of piston rod.
Embodiments of the invention as shown in drawings.
Fig. 1 is a schematic side view of the present invention.
Fig. 2, Fig. 3 are trenching machine working state schematic representations of the present invention, and wherein Fig. 2 is a rear elevation, and Fig. 3 is a lateral view.
Explanation to number in the figure:
1, motor, 2, front clutch, 3, hydraulic pump, 4, first output shaft, 5, final drive shaft, 6, first fluid pressure line, 7, second fluid pressure line, 8, second output shaft, 9, first hydraulic cylinder, 10, second hydraulic cylinder, 11, rocking bar, 12, the chain cutter, 13, chain knife rest, 14, volume dragon, 15, spiral bevel gear, 16, rack beams, 17, spiral bevel gear, 18, the output shaft of advancing, 19, back clutch, 20, the gap bridge gearbox, 21, rear cross beam.
Accompanying drawing is described in detail the present invention in conjunction with the embodiments:
On the wheel shaft of the front and back of basic car, establish rack beams 16.On the final drive shaft between motor 1 and the hind axle 5, set up a gap bridge gearbox 20.Between motor 1 and gap bridge gearbox 20 and gap bridge gearbox 20 and advancing respectively adorn a front clutch 2 and back clutch 19 between the output shaft 18.The gearbox of advancing between clutch 19 and spiral bevel gear 17 omits among this figure.Draw two power output shafts 4 and 8 in final drive shaft 5 one sides in the gap bridge gearbox 20, power output shaft 4 drives hydraulic pump 3, connects with hydraulic cylinder 9,10 respectively by pipeline 6,7.Hydraulic cylinder 9,10 and rocking bar 11 are formed the double hydraulic cylinder endplay device, and double hydraulic cylinder endplay device connecting rack beam 16 and chain knife rest 13 can drive chain knife rest 13 serve as that axle is done gyration with rear cross beam 21.Chain knife rest 13 support chain cuttves 12, the chain of chain cutter 12 connects with the driven wheel engagement of volume dragon 14.Power output shaft 8 in the gap bridge gearbox 20 connects drive chain cutter 12 by Cardan shaft with spiral bevel gear 15.The operating principle of trenching machine of the present invention is to utilize the motor of basic car to be used as power, and draws the power of hydraulicefficiency elevation structure and the power of digging mechanism respectively by the gap bridge gearbox of setting up.In use basic car is parked in construction place, pluck clutch 2 and 19 and make the race of engine, elder generation in gear 2, steering maneuver output shaft 4 drives hydraulic mechanism then, promote the piston rod of hydraulic cylinder 9, under rocking bar 11 participates in, chain knife support 12 put down on the ground that places the construction soil and drive hydraulic mechanism again, promote the piston rod of hydraulic cylinder 10.While steering maneuver output shaft 8 drive chain cuttves 12, chain cutter 12 drives volume dragon 14, the beginning ditching, dig from ground earlier, under hydraulic cylinder 10 effects, excavate, during to desired depth to the depths, the state that keeps hydraulic mechanism, clutch 19 is hung up, and main shaft 5 drives bevel gear 17 by axle 18 and gearbox, and basic car is advanced according to required speed.Advance in the limit, the limit ditching.By chain cutter 12 is discharged to ditch with soil zone to volume Long14Chu.Dig obstruction sometimes in construction, the swaging clamp accident takes place, the measure of solution is to add an overflow valve in the elevating lever landing loop in hydraulic mechanism.Do not indicate among the figure, come out but be easy to the imagination.Advance when running into big resistance when the chain cutter, hydraulic system can be lifted chain knife rest 13 under the overflow valve effect automatically, and operating hydraulically operated again mechanism sets back the chain knife rest when surpassing obstacle.The chain cutter can need be equipped with several covers by different in width according to construction, and its specification is between 150～300 millimeters.
Trenching machine type of the present invention is little, and the chain knife rest can be contained in the middle of the rear cross beam, also can be contained in rear cross beam one side, easily in constructing in narrow street, city.
