Description
Technical field
The utility model relates to a kind of farming operation machinery, particularly is power, multiduty electric tiller with electric power.
Background technology
Traditional farming operation machinery is to be power with the internal combustion engine, discharging large quantity of exhaust gas during work, and noise is bigger, pollute inevitably, and fuel price is constantly soaring, causes use cost to improve.Existing tiller is general with the combustion engine powered gearbox that passes to, be distributed to running gear and ploughing system again, realize transmission and speed change by gear mechanism, according to job requirements, often needing rotating speed to fall afterwards earlier rises, this just causes transmission system complicated, and it is bigger to wear and tear, and the reliability and the service life of complete machine all are affected.The colter lifting of existing tiller is often relatively required great effort and is bothered, and the firming roller is by the deadweight firming behind the machine, and effect is bad.In addition, existing tiller generally is the special plane special use, and range of application is restricted.
The utility model content
The purpose of this utility model is to overcome the weak point of existing tillage machinery, provides that a kind of serviceability is good, pollution-free, cost is low, the electric tiller of applied range.
The technical solution of the utility model is: electric tiller comprises chassis, power drive system, running gear, ploughing system, improvements are to be provided with motor, belt gear and gearbox in the described power drive system, motor output shaft is connected with coulter shaft in the ploughing system by belt gear, and be connected with traction drive axle in the running gear by belt gear and gearbox, the power line of motor is wrapped on the take-up reel that is driven by belt gear, and the side of this take-up reel is provided with electromagnetic attracting device and freewheel clutch.
Be provided with the colter hoisting mechanism in the described ploughing system, this mechanism mainly is made of support arm, otic placode, steel wire rope, runner, the lower end of described support arm links to each other with coulter shaft, counterweight is equipped with in the upper end, the middle part is connected with hitching axis in the ploughing system, the counter pulley center line coaxial line in hitching axis center line and the belt gear that is connected coulter shaft, and described otic placode symmetry is fixed on the above-mentioned hitching axis, the otic placode outer end links to each other with the steel wire rope of walking around runner, and runner is provided with handle and locking member; Described locking member is made of with the tooth plate that is positioned at the runner side the backing pin that is contained on the runner; Be provided with the thread take-up tension lever that is fixed on the chassis in the described power drive system, the pulley that motor power-supply wire is walked around on the thread take-up tension lever is connected with fixed power source; Be provided with the firming roller that links to each other with spring in the described ploughing system, this spring is fixed on the back side panel on chassis; Be provided with reverse box in the belt gear of described connection motor output shaft and traction drive axle.
Adopt above scheme, it is power that this tiller replaces internal combustion engine with motor, is a breakthrough to conventional tillage mechanomotive force system, its advantage is that electricity consumption is pollution-free, noiseless, cost are low, and motor is next compared with internal combustion engine, and installation, maintenance all makes things convenient for, and also has superiority on volume, the weight.The difficult point that solves is the connection and the folding and unfolding of motor power-supply wire, this tiller adopts the take-up reel that has electromagnetic attracting device and freewheel clutch, have under the sufficiently long situation at power line, realize the walking take-up synchronously automatically under belt gear drives of the idle running unwrapping wire of take-up reel and take-up reel with tiller; And power line is lifted by thread take-up tension lever, can not disturb operation and sustains damage, and is safe and reliable.This tiller mainly passes through belt---and pulley mechanism realizes transmission and deceleration, reduces the wearing and tearing of high-power transmission middle gear transmission, helps the raising in whole aircraft reliability and service life.The utility model adopts unique colter hoisting mechanism, as long as the operator is sitting on the machine, control crank is lifting colter neatly just, and is not only laborsaving but also make things convenient for, and can lock, and during the colter lifting, the rate of tension of driving belt is not affected.Firming roller in the ploughing system relies on the strength of spring but not by gravity pressure earthward, easy to adjust, firming is effective.The utility model can change turning to of motor easily, carry out positive rotary tillage, derotation cultivated, reverse stubble-cleaning or other operation of ploughing system, in corresponding belt gear, reverse box is set, make behind the motor steering, road wheel still keeps moving ahead, thereby the realization a tractor serves several purposes enlarges range of application.
