Abstract

The utility model belongs to the rotary cultivator cutter technical field and discloses a rotary cultivator cutter for the stalk returning to the soil, which is characterized technically by comprising a cutter body, at the end of which is positioned a horizontal blade perpendicular to the cutter body, between the cutter body and the horizontal blade is positioned a vertical blade in the same direction of the cutter body. For further improvement, the height of the vertical blade provided at the side of the horizontal blade is higher than that of the horizontal blade. The problem is solved that, due to the structural shortcomings, current rotary cultivators have complicated structure, difficult maintenance, high production cost and poor comminution efficiency of stalk roots. The object of simultaneous stalk comminution and cultivation can be achieved just by applying the rotary cultivator cutters for the stalk returning to the soil of the utility model in current rotary cultivators.

Description

The straw application rotary cultivator cutter
Technical field
The utility model belongs to rotovator cutter technical field, relates in particular to the straw application rotary cultivator cutter.
Background technology
For crops such as corn etc., most straw-returnings that adopt so not only help soil moisture conservation, but also can provide fertilizer for next batch crop.At present, as the rotovator cutter employing straight knife and the crooked cutter in farming farmland, there is the single shortcoming of function of use in this rotovator.Straw application rotary cultivator adopts mostly installs independent crushed stalk mechanism on large-scale rotovator, like this, after crushed stalk, rotovator makes straw-returning and farming once finish again with soil cultivating.This big machinery complex structure is not easy to safeguard the production cost height; Can not pulverize well for the stalk root, only pulverize by the rotovator cutter, crushing effect is poor, makes the seed of next batch crop drop on the stalk root, influences emergence rate.And on the soil of area broadness farming can, for the fritter field of every household, just impracticable.
The utility model content
Technical problem to be solved in the utility model just provide a kind of can either crushing straw and the stalk root can carry out farming and straw application rotary cultivator cutter simple in structure, that cost is low again.
For solving the problems of the technologies described above, the technical scheme that straw application rotary cultivator cutter provided by the utility model adopts is: comprise cutter hub, be provided with vertical with it horizontal blade in described cutter hub end, between described cutter hub and horizontal blade, be provided with the vertical blade consistent with the cutter hub direction.
Its additional technical feature is: described vertical blade is umbilicate camber; Described vertical blade is middle protruding camber; The height that described vertical blade is positioned at horizontal blade one side is higher than the height of horizontal blade; The both wings of described horizontal blade are to cutter hub one lateral bending song.
Straw application rotary cultivator cutter provided by the utility model compared with prior art, have the following advantages: one, owing to be provided with vertical with it horizontal blade in the cutter hub end, between cutter hub and horizontal blade, be provided with the vertical blade consistent with the cutter hub direction, horizontal blade blocks the stalk consistent with the cutter hub direction, and vertical blade will block with the stalk that the cutter hub direction intersects, and for horizontal blade, vertical blade has also played the effect of reinforcement, has prevented horizontal blade flexural deformation; Its two because vertical blade is positioned at the height that the height of horizontal blade one side is higher than horizontal blade, when cutter fell, vertical blade end at first landed and scratches hard epidermis, more ploughs well for stiff plot.
Description of drawings
The structural representation of the straw application rotary cultivator cutter that Fig. 1 provides for the utility model;
Fig. 2 is the structural representation that has the straw application rotary cultivator cutter of another kind of horizontal blade.
Embodiment
Be described in further details below in conjunction with the structure of the drawings and specific embodiments the utility model straw application rotary cultivator cutter.
As shown in Figure 1, the straw application rotary cultivator cutter comprises the cutter hub of being made by metal material 1, has fixing hole 2 at an end of cutter hub 1, and fixing hole 2 also can be designed to two or more as required.Fixed forms such as other end employing welding at cutter hub 1 are provided with vertical with it horizontal blade 3.The fixed forms such as side employing welding that are positioned at horizontal blade 3 at cutter hub 1 are provided with vertical blade 4, and vertical blade 4 welds together with horizontal blade 3.3 have first blade 5 on horizontal blade.A side that deviates from cutter hub 1 at vertical blade 4 is that second blade, 6, the second blades 6 are designed to be umbilicate camber, also can be the protruding camber in centre (not drawing among the figure).The height that vertical blade 4 is positioned at horizontal blade 3 one sides is higher than the height of horizontal blade 3.
As shown in Figure 2, the both wings 7 of horizontal blade 3 are to a lateral bending song of cutter hub 1.
During use, common rotovator cutter is taken off, replace with the utility model straw application rotary cultivator cutter, under the situation that other place does not need to change, just can realize getting final product the purpose that crushing straw again can the farming field.

Claims (5)

1, the straw application rotary cultivator cutter comprises cutter hub, it is characterized in that: be provided with vertical with it horizontal blade in described cutter hub end, be provided with the vertical blade consistent with the cutter hub direction between described cutter hub and horizontal blade.
2, straw application rotary cultivator cutter according to claim 1 is characterized in that: described vertical blade is umbilicate camber.
3, straw application rotary cultivator cutter according to claim 1 is characterized in that: described vertical blade is middle protruding camber.
4, straw application rotary cultivator cutter according to claim 1 is characterized in that: the height that described vertical blade is positioned at horizontal blade one side is higher than the height of horizontal blade.
