Abstract

The invention discloses a micro-farming machine, which is mainly characterized in that the rotary cultivator adopts two or more groups of direct and reverse reamers to cut soils in contra rotating type, which enables the depth of farming between 18 and 20 cm, improves farming efficiency, realizes stable and even farming, solves problems of grass wrapping of the micro-farming machine in existence, play when farming on hard soil and soil accumulation when farming on clayey soil, thus strengthening the safety.

Description

A kind of two groups of cuttves reverse rotation simultaneously formula is cut soil, antiwind mini-size tillage machine

One, technical field

The present invention relates to the agricultural tillage machine particularly two groups or more cutter convection rotary type cut soil, high steady, antiwind tiller.Can increase substantially whole serviceability, extend to whole tiller (see figure 1).

Two, technical background

There is following problem in the mini-size tillage machine of prior art:

1, revolve cutter with road wheel rotates in the same way because the hilted broadsword rotovator adopts, the soil property summary will cause whole machine out of control firmly in ploughing native process, fierce play forward, cause balk, complete machine plants, and has serious machine, personal safety hidden danger.

2, during farming not steadily, not at the uniform velocity, to plough the native degree of depth not enough.In case of than pan soil matter, one time tilling depth can only reach about 5 centimetres, and the required tilling depth of peasant is 15-20 centimetre, differs greatly with rural demand.

3, when running into the field that weeds are arranged, can twine long-pending many weeds on the rotary blade, directly influence tilling depth and farming efficient.

4, as run into rain after the field of more glutinous matter (clay), can the many earth of accumulation on the rotary blade, the farming load is increased the weight of, turn to effort, tilling depth is shallow, it is slow to plough speed.

More than 4 be to cause former machine for the used main cause of peasant.After changing double-pole or multitool convection rotary type into, more than 4 problems be readily solved, major advantage is as follows:

1, tilling depth reaches between 18-20 centimetre, and efficient reaches per hour 0.8-1 mu.

2, do not twine weeds on the rotary blade.

Even 3 on hard soil, also can realize steadily ploughing at the uniform velocity forward into (when the straight line farming, not needing the people to slap handrail).

4, as running into glutinous matter field (clay), the long-pending soil of rotary blade is few, does not influence normal farming.

Three, technical scheme

(1) preceding transmission and fastening structure are: 2. 1. positive rotary tillage tooth be fixed on positive rotary tillage shaft by key and 3. go up, positive rotary tillage shaft two ends cover upper bearing (metal) 4., sealing ring 5., lining 6..Bearings at both ends 4., sealing ring 5. be contained in the rotary tillage axle bed 7. in, 8. be fixed on 9. two ends of first group of girff body with screw, 1. just changeing transmission by positive rotary tillage tooth and give to pass a bridge little tooth 10., 10. little tooth is reversed.Cross the little tooth of sedan-chair 10. fixing means be: pass a bridge little tooth 10. endoporus pass bridge mandrel , be fixed in second group of casing with nut

On, by pass a bridge little tooth 10. transmission give the little tooth  of break-in.The fixed structure of the little tooth  of break-in is 10. identical with the little tooth of passing a bridge.The little tooth  of break-in transmission again ploughs tooth  to derotation, realizes anti-rotary tillage shaft  counter-rotating.3. fixed structure is identical with positive rotary tillage shaft for anti-rotary tillage shaft  fixed structure.Cutter tube  by cross screw  be connected positive rotary tillage shaft 3. with anti-rotary tillage shaft  on.Method of attachment is: rotary tillage shaft outer six sides be connected with six side's interference fits in the cutter tube.Blade  passes through screw Be connected fixed head

On, fixed head

Be welded on the cutter tube .

(2)

1, adopt positive and negative two groups of cuttves to rotate simultaneously and plough soil, two groups of cutter rightabouts rotations, the point of a knife rotating diameter of two adjacent groups blade intersects, the cutter arrangement (see figure 2) that staggers mutually.Also can increase the 3rd group of cutter, realize two groups just change, one group the counter-rotating (see figure 3).Or two groups of counter-rotatings, one group is just being changeed (see figure 4).First group of cutter and road wheel direction in opposite directions, second group of cutter opposite configuration seen Fig. 2.If first group of cutter is opposite with road wheel, second group of cutter is identical with the road wheel direction, its farming effect and the identical (see figure 5) of purpose.

2, can adopt road wheel to spur two groups of rotary blade farming (see figure 2)s, also can promote two groups of rotary blades and carry out the farming (see figure 6) by road wheel to engine.

3, cutter arrangement: cutter arrangement is divided many kinds, can arrange according to peasant user's needs, as adopting first group of cutter to divide four rows, two cuttves of every row, camber above the cutter is divided left and right directions, the edge of a knife is along direction of rotation, and first group of cutter and second group of cutter intersect the (see figure 2) that staggers mutually, also can exchange (see figure 7) by two groups of cuttves.

Four, the advantage of this invention and effect

This invention has following advantage:

1, during two groups of cuttves reverse rotation simultaneously farming, the active force of giving ground is that positive and negative direction is simultaneously stressed, thereby has solved machine in cultivating procedure, and the problem of play forward with sudden force when running into than pan soil matter realizes that steadily average rate is farming forward.Land readjustment after the farming, no plough-leaking phenomenon.

2 liang of group cuttves are equivalent to twice original tilling depth effect to revolving, even if very hard soil property also can reach disposable tilling depth requirement.

3, two groups of cuttves have solved the original problem that twines grass to revolving.If the cutter of first group of cutter

Grass is arranged in the air, during second group of cutter reverse rotation, careless tricky (take out, get) of first group of cutter can be gone out.In like manner, there are weeds also to go out in second group of cutter by first group of cutter is tricky.Many group cuttves in like manner.

4, two groups of cuttves have also solved former rotary blade as running into the field of the glutinous matter in back (clay) of raining, the extremely many problems of deposition on the rotary blade to revolving.Structure reduces deposition in a large number now, alleviates the complete machine load, has improved operating efficiency, its principle the same 3.
