Abstract

The utility model discloses a winding grass prevention rotary tillage cutter shaft, wherein a rotary tillage cutter blade and a cutter holder are fixed on the rotary tillage cutter shaft; a grass cutting blade is mounted on the rotary tillage cutter shaft; grass can be cut into two sections under the action of grass cutting blade in case of grass winding during the rotating process of the rotary tillage cutter shaft; and when the grass is shorter than the circumference of the rotary tillage cutter shaft, and the phenomenon of grass winding can be eliminated automatically. The utility model solves the problem of grass winding during the rotary tillage, and improves the production efficiency under the premise of ensuring the quality of rotary tillage.

Description

A kind of anti-careless rotary ploughing cutter shaft that twines

Technical field

The utility model relates to and a kind ofly anti-twines careless device, especially relates in a kind of shallow plowing or the deep ploughing and prevents twining careless rotary ploughing cutter shaft.

Background technology

Existing rotary ploughing cutter shaft is in the rotary tillage operation process; mainly contain the deep ploughing and the two kinds of operating types of ploughing shallowly; select for use blade to mainly contain the right angle cutter; tulwar; scalpriform blade etc.; because the field can be left residual crops for rotation of preceding crop or spontaneous weeds unavoidably in the operation process; therefore run into weeds or crop stem winding rotary ploughing cutter shaft through regular meeting in the rotary tillage operation process; progressively be increased to when consistent to twining careless radius with cutter diameter; cause the rotary tillage can't normal operation; must shut down cleaning, influence work production efficient.

The utility model content

The technical problem that the utility model solved is: a kind of anti-careless rotary ploughing cutter shaft that twines is provided, solves the problem in the background technology.

The technical problem that the utility model solved realizes by the following technical solutions:

A kind of anti-careless rotary ploughing cutter shaft that twines, mainly comprise, flange, rotary ploughing cutter shaft, Rotary tillage blade, tool rest, cutting grass knife, described Rotary tillage blade and tool rest are fixed on the rotary ploughing cutter shaft, and cutting grass knife is installed on the rotary ploughing cutter shaft, have in the rotary ploughing cutter shaft rotary course under the situation of grass winding, under the effect of cutting grass knife, grass is cut into two sections,, twines careless phenomenon and eliminate automatically when the length of weeds during less than the circumference of rotary ploughing cutter shaft.During work, owing to always occur certain space between the adjacent blade of rotary tillage, promptly cut the blind area, therefore created a chance of exempting to cut to weeds, so, high speed rotating along with rotary ploughing cutter shaft, weeds are with rotary ploughing cutter shaft immediately, when the length of weeds surpasses the caliber girth of rotary ploughing cutter shaft, just can tightly be wrapped on the rotary ploughing cutter shaft, the gap of adjacent tool rest is progressively filled up, therefore the close tulwar back side one side between adjacent tool rest, a kind of cutting grass knife is installed, the blade cutting edge direction is parallel with the rotary ploughing cutter shaft axis, and the blade radial symmetric is welded on the rotary ploughing cutter shaft, and width is about 1/2 of adjacent tool rest spacing, height is slightly less than the setting height(from bottom) of tool rest between tool rest and rotary ploughing cutter shaft cylindrical.When operation is deep ploughed or ploughed shallowly to rotary ploughing cutter shaft, leaked the weeds or the not cut weeds that cut by Rotary tillage blade and twine rotary ploughing cutter shaft along circumference, when weeds are cooked in the winding process, because the cutting edge secondary cutting effect of cutting grass knife, add to twine and tighten under the effect of power, weeds are immediately by complete cut-out, when the length of weeds during less than the rotary ploughing cutter shaft girth, just the ground of dropping, by Rotary tillage blade chopping again next time, solved the problem that rotary tillage twines grass, guaranteed to have improved production efficiency under the prerequisite of rotary tillage quality.

Beneficial effect:

The utility model has following advantage: (1) anti-to twine careless rotary ploughing cutter shaft and is adapted to deep ploughing and shallow plowing operation, and especially solving the shallow plowing operation, to twine grass more effective; (2) the chaffcutter straight knife sheet of symmetry installation is simple in structure, light weight, and motion is steadily processed easy for installation; (3) chaffcutter straight knife sheet cutting edge adopts the single face cutting edge, and processing and fabricating is convenient; (4) adjacent two chaffcutter straight knife sheets can arrange be arranged according to spiral fashion, also can arrange according to axial collinear, radial symmetric, can guarantee the chaffcutter quality equally.

Description of drawings

A kind of anti-careless rotary ploughing cutter shaft accompanying drawing that twines of Fig. 1 the utility model;

A kind of anti-careless rotary ploughing cutter shaft cutting grass knife enlarged drawing that twines of Fig. 2 the utility model.

Embodiment

For technological means, creation characteristic that the utility model is realized, reach purpose and effect is easy to understand, below in conjunction with concrete diagram, further set forth the utility model.

With reference to Fig. 1, a kind ofly anti-twine careless rotary ploughing cutter shaft, mainly comprise flange 1, rotary ploughing cutter shaft 2, Rotary tillage blade 3, tool rest 4, cutting grass knife 5.

A kind of anti-careless rotary ploughing cutter shaft that twines, Rotary tillage blade 3 and tool rest 4 are fixed on the rotary ploughing cutter shaft 2, cutting grass knife 5 is installed on the rotary ploughing cutter shaft 2, in rotary ploughing cutter shaft 2 rotary courses, have under the situation of grass winding, under the effect of cutting grass knife 5, grass is cut into two sections,, twines careless phenomenon and eliminate automatically when the length of weeds during less than the circumference of rotary ploughing cutter shaft 2.During work, owing to always occur certain space between the adjacent blade of rotary tillage, promptly cut the blind area, therefore created a chance of exempting to cut to weeds, so, high speed rotating along with rotary ploughing cutter shaft 2, weeds are with rotary ploughing cutter shaft 2 immediately, when the length of weeds surpasses the caliber girth of rotary ploughing cutter shaft 2, just can tightly be wrapped on the rotary ploughing cutter shaft 2, the gap of adjacent tool rest is progressively filled up, therefore the close tulwar back side one side between adjacent tool rest 4, a kind of cutting grass knife 5 is installed, the blade cutting edge direction is parallel with the rotary ploughing cutter shaft axis, and the blade radial symmetric is welded on the rotary ploughing cutter shaft 2, and width is about 1/2 of adjacent tool rest spacing, height is slightly less than the setting height(from bottom) of tool rest between tool rest 4 and rotary ploughing cutter shaft 2 cylindricals.When operation is deep ploughed or ploughed shallowly to rotary ploughing cutter shaft 2, leaked the weeds or the not cut weeds that cut by Rotary tillage blade 3 and twine rotary ploughing cutter shaft 2 along circumference, when weeds are cooked in the winding process, because the cutting edge secondary cutting effect of cutting grass knife 5, add to twine and tighten under the effect of power, weeds are immediately by complete cut-out, when the length of weeds during less than rotary ploughing cutter shaft 2 girths, just the ground of dropping, by Rotary tillage blade 3 chopping again next time, solved the problem that rotary tillage twines grass, guaranteed to have improved production efficiency under the prerequisite of rotary tillage quality.

The above only is a preferred implementation of the present utility model, and protection domain of the present utility model also not only is confined to the foregoing description, and all technical schemes that belongs under the utility model thinking all belong to protection domain of the present utility model.Should be pointed out that for those skilled in the art in the some improvements and modifications that do not break away under the utility model principle prerequisite, these improvements and modifications also should be considered as protection domain of the present utility model.
