Description
Technical field
The present invention relates to a kind of agricultural machine more particularly to a kind of steady light mini-tillers.
Background technique
Farmland will plough in advance before planting, and there are mainly two types of tillage methods during arable land for existing mini-tiller: one
Kind is ploughing, and another kind is rotary tillage；The advantages of ploughing is that topsoil is deep, active soil stratum is thick, can translate into ground for the fertilizer for spreading on the ground
Under face, therefore it can make that the farmland solubization ploughed is good, fertilizer reserve strength foot；But the farmland ploughed with ploughing, large clod are more, broken
Soil is few, and native face is uneven, has certain adverse effect to germination, the growth of crop.Rotary cultivator have the characteristics that it is opposite with ploughshare,
I.e. topsoil is shallow, soil block is thin, and more, the native face of the farmland hack ploughed is flat and fertilizer is evenly distributed；But since the topsoil of rotary tillage is shallow, because
And the drought resistance in soil is poor, fertilizer lacks of staying power.Therefore peasant household has to use first is revolved with rotary cultivator with ploughing deep ploughing once, again
Primary method is ploughed, with the arable land effect reached.And this undoubtedly forms repeated labor, results in the liter of production cost
Height brings bigger financial burden to peasant household.
Meanwhile existing mini-tiller all has the following problems in the cultivating procedure of two kinds of tillage methods:
1, ploughing: the tractive force by wheel advances, if soil resistance becomes larger, ploughing knife is obstructed, and wheel will skid, and needs
Operator's regulating plough grease head highness frequently is wanted, resistance is reduced.
2, rotary tillage: tilling depth is not easy to adjust, and cutter makes the wheel of rotation be polygon, therefore when machine operation, front and back, on
Under have biggish vibration, compare expend operator's physical strength；If suddenly encountering larger resistance, cutter skids, and can only raise fuselage
Adjust cutting depth.
This not only gives farming bring greatly inconvenient, expends physical strength in the extreme, and farming efficiency is also low.
Summary of the invention
In view of the above shortcomings of the prior art, the purpose of the present invention is to provide a kind of steady light mini-tiller, energy
Enough steadily, farming is rapidly carried out, and drill angle is easy to adjust, quick, easy to operate and time saving and energy saving, farming efficiency is more
It is high.
In order to solve the above-mentioned technical problem, the technical solution adopted by the present invention is that it is such: a kind of steady light mini-tiller,
Including rack, handrail, prime mover, gear-box, drill and traveling wheel, the two sides phase of the rear end of the front end and rack of the handrail
Even；The traveling wheel is two, and two traveling wheels are located at rack two sides, and are connected by a wheel shaft；The wheel shaft passed through
It crosses bearing to be connected with rack, and the wheel shaft is close to the front end of rack；It is characterized by: the gear-box is integrally T-shaped comprising
Preceding cabinet along the setting of rack front-rear direction and the rear box along the setting of rack left and right directions, and preceding cabinet and the fixed company of rear box
It is connected together；The preceding cabinet is installed on wheel shaft by spring bearing, and can be rotated around the axial line of wheel shaft；In rack
The position of side, corresponding rear box is equipped with a screw rod vertically, and the upper and lower part of the screw rod passes through a positioning seat and machine respectively
It is connected on the inside of frame, the upper end of the screw rod is connected with a turntable；Cooperation is equipped with a feed screw nut on screw rod, solid on feed screw nut
Surely it is connected with a bolt；In rear box close to one end of screw rod, the position of corresponding bolt is equipped with an adjusting block, on the adjusting block
A jack is offered along the front-rear direction of rack, one end of the bolt is connected with feed screw nut, and the other end protrudes into the jack,
By rotating turntable, the axial line for being able to drive gear-box around wheel shaft is rotated；
Described prime mover is fixedly connected with rear box, and output shaft is connected by a shaft coupling with a worm screw, the worm screw
Through gear-box, both ends pass through a transition bearing respectively and are connected with gear-box；One and snail are equipped in the preceding cabinet of gear-box
The worm gear of bar cooperation, the worm gear are set on wheel shaft and are fixedly connected with wheel shaft；It is main that one is equipped in the rear box of gear-box
Moving gear and a driven gear, the driving gear is set on worm screw, and is fixedly connected with worm screw, and the driven gear passes through
Support shaft is connected with rear box, and meshes together with driving gear, and the both ends of the support shaft also pass through a transition axis respectively
It holds and is connected with rear box；
The drill is two comprising the front end of knife bar and blade, the knife bar is tapered, the blade spiral winding
In the front of knife bar；Wherein, the rear end of a knife bar is connected by shaft coupling with worm screw, and the rear end of another knife bar passes through shaft coupling
Device is connected with the front end of support shaft.
Further, in the downside of rack at rear end be equipped with a support wheel, the support wheel by a connection frame with
Rack is connected.
Further, the worm gear and worm screw cooperatively form as deceleration worm gear worm mechanism.
Further, described prime mover is gasoline engine or motor.
Compared with prior art, the present invention has the advantage that
1, by rotation turntable, drill can be adjusted to a suitable angle of penetration (tilling depth), pass through different tilling depth
The structure for cooperating drill translates into following soil to come above, to respectively reach the effect of ploughing and rotary tillage；It operates more square
Just, fast, so as to larger reduction operator's labor intensity.
2, drill front-end architecture is similar with drill bit structure, during arable land with rotation, to hard soil have compared with
Good destruction to further decrease the labor intensity during arable land, and improves farming efficiency.
3, prime mover rotates cutting soil for drill simultaneously and wheel is walked；Although prime mover revolving speed is high, due to drill
It is the same rotation of drill bit, therefore will not influence cutting soil；If suddenly encountering larger resistance, can rotational handle at any time, change
Become drill angle of penetration (tilling depth), does not need to lift entire vehicle body, it is convenient, it is laborsaving.
4, power is shared simultaneously with vehicle wheel rotation two movements due to being Tool in Cutting rotation, cutter is hampered, and rotation is slack-off,
After worm and wormwheel constant-speed ratio is transmitted to wheel, wheel is automatically slack-off；Therefore, when suddenly encountering resistance, it can effectively avoid the occurrence of and beat
Sliding phenomenon.
5, vehicle frame, balance and stability, drill rotary cutting mistake are supported by three-wheel (two traveling wheels, a support wheel) jointly
Shaken in journey it is smaller, so as to make state of runtime machine more stable.
