Abstract
Stalk crushes buried returning to the field knife and belongs to agricultural machinery；Stalk crushes buried returning to the field knife and is made of rectangular steel plates of the one block length × width x thickness by 217 × 80 × 9 millimeters, with on one long side of rectangular steel plates from one end to the point portion of 112 millimeters of length and to be divided into shank section and cutter hub portion to standing rectangular steel plates to bending at connecting line between the point portion of 53 millimeters of length from same end on another long side of rectangular steel plates, within angle between the shank section and cutter hub portion is 103 °, first and second cutting edge is opened up on the short side end face in the cutter hub portion, mounting hole is opened in shank section；This knife technical parameter determine it is scientific and reasonable, it is simple in structure, compact, fabricate simple and convenient, low production cost, integral strength is high, and using reliable, hack and the buried ability of stalk crushing are strong, effect is good.
Description
Technical field
The utility model belongs to agricultural machinery, relates generally to a kind of stalk being fitted on tillage implement and crushes buried returning to the field
Cutter.
Background technology
The design of used straw stalk pulverizing knife knife-edge is more complicated, and integral strength is poor, except there are manufacturing processing technic it is complicated,
Outside many technical matters such as production cost height, failure rate height, the buried energy force difference especially to stalk, influences and reduces work
Industry quality and effect.
The content of the invention
The purpose of this utility model provides a kind of straw of new construction aiming at the above-mentioned problems of the prior art, design
Stalk crushes buried returning to the field knife, reaches simplified structure, reduces manufacture cost, ensure performance, increase substantially the buried energy of stalk
The purpose of power.
The Basic Design of the utility model is:It is by a block length H that the stalk, which crushes buried returning to the field knife,1× wide S × thickness T is
217 × 80 × 9 millimeters of rectangular steel plates are made, with one long side of rectangular steel plates from one end to length H3For 112 millis
Rice point portion with another long side of rectangular steel plates from same end to length H2The connecting line between 53 millimeters of point portions
Place, which stands rectangular steel plates to bending, is divided into shank section and cutter hub portion, and the within angle α between the shank section and cutter hub portion is 103 °,
The first cutting edge and the second cutting edge are opened up on the short side end face in the cutter hub portion, mounting hole is opened up in the shank section,
So far form stalk and crush buried returning to the field knife.
The utility model technical parameter determine it is scientific and reasonable, it is simple in structure, compact, fabricate simple and convenient, be produced into
This is cheap, and integral strength is high, and using reliable, hack and the buried ability of stalk crushing are strong, effect is good.
Brief description of the drawings
Fig. 1 is that stalk crushes buried returning to the field knife structure expanded view；
Fig. 2 is that stalk crushes buried returning to the field knife structure diagram；
Fig. 3 is the A direction views of Fig. 2.
Piece number explanation in figure：
1st, mounting hole, 2, shank section, 3, cutter hub portion, 4, rectangular steel plates, the 5, first cutting edge, the 6, second cutting edge.
Embodiment
The utility model embodiment is described in detail below in conjunction with the accompanying drawings.A kind of stalk crushes buried returning to the field knife,
It is by a block length H that the stalk, which crushes buried returning to the field knife,1× wide S × thickness T is that 217 × 80 × 9 millimeters of rectangular steel plates 4 are made,
With on 4 one long sides of rectangular steel plates from one end to length H3For 112 millimeters of point portions with it is another long with rectangular steel plates 4
To length H from same end on side2Rectangular steel plates 4 are stood to bending at connecting line between 53 millimeters of point portions and are divided into handle of a knife
Portion 2 and cutter hub portion 3, the within angle α between the shank section 2 and cutter hub portion 3 is 103 °, in the short side end face in the cutter hub portion 3
On open up the first cutting edge 5 and the second cutting edge 6, open up mounting hole 1 in the shank section 2.
During operation, stalk crush the rotation of buried returning to the field knife whole reverse, the first cutting edge 5 and two cutting edges 6 to soil and
After stalk completes effective cutting and grinding twice at the same time, under shank section 2 and 3 counter-rotating of cutter hub portion effect, by soil and stalk
Throw to rear and complete straw-returning and buried operation.
