Abstract
The utility model discloses a kind of biasing of reversal stubble cleaning rotary cultivator directly to turn over rotary blade, belong to agricultural machinery technological field, cutter tool apron is fixed using diplopore, blade uses interior kinking structure, opened up on Sidelong portion fluted, groove location is corresponding with blade, Sidelong portion is welded in the groove opened up with blade, Sidelong portion is put relative to blade, positive cutting blade design triangle cutting edge, positive cutting blade is triangle, trapezoidal or inclined-plane, and Sidelong portion lower part is welded reinforcing rib along blade both sides, is mainly used on the loose less soil of taxi earth and soil intermolecular forces.
Description
Technical field
Agricultural machinery technological field is the utility model is related to, is specially that a kind of reversal stubble cleaning rotary cultivator biasing directly turns over rotary tillage
Knife.
Background technology
Rotary cultivator is the common tool in agricultural production, by power, soil is carried out fragmentation, is mainly used for cultivating, broadcasts
Farming before kind, makes soil soft, smooth, meets the requirement of intensive cultivation, and still, existing rotary cultivator still has as follows not
Foot：The usual supporting rotary blade of reversal stubble cleaning rotary cultivator has common standard rotary blade, T-shaped right angle knife etc..This kind of blade structure
On have a feature, Sidelong portion opposite side section bending forming.During work, lateral incision sword cuts soil, the bottom of positive cutting blade cut-out upturned soil
The angle of portion, Sidelong portion and Zinc fractions, can take up upturned soil.The angle formed due to standard rotary blade Sidelong portion and lateral incision face
120 ° or so, there is an active force outwards backward to the upturned soil taken up, upturned soil is dished out to side rear；T-shaped right angle knife is in theory
90 ° of the angle that Sidelong portion is formed with lateral incision face, upturned soil are dished out after taking up backward.It is big that the amount of the defeated native ability of cutter depends on Sidelong portion
Spatial volume size that small and Sidelong portion and lateral incision face are formed, when being unearthed with blade and the angle of earth's surface, soil types blade
Rotary speed etc. is related, when soil is in small, broken bits loose, it is desirable to which blade rotary speed is big, just can guarantee that enough defeated native abilities.It is supporting
Such cutter, tilth is different, and the upward band soil ability of cutter is different, and the rotary speed of cutter influences Overall Power Consumption size
Very big, rotary speed is subject to certain restrictions.For the loose soil of arid, such as loam, sandy loam, weeds in soil, plant
Thing stubble is few, and soil is in small, broken bits loose, and soil intermolecular forces are smaller, and cutter side cutting blade, which needs, necessarily cuts native ability, using routine
Standard rotary blade, T-shaped right angle knife, the band soil ability that lateral incision face and Sidelong portion act on backward can not meet the requirements, the soil taken up
Upturned soil is easily dropped, and is formed repeatedly cutting, is caused Overall Power Consumption to increase.Equipment cutter shaft both sides, which use to be arranged symmetrically, directly turns over rotary blade,
Cutter stress is big, and positive cutting blade easily snaps off.
Utility model content
In order to solve the above-mentioned technical problem, a kind of reversal stubble cleaning rotary cultivator biasing of the offer of the utility model directly turns over rotary tillage
Knife, the technical solution of use are as follows：
A kind of reversal stubble cleaning rotary cultivator biasing directly turns over rotary blade, and cutter tool apron is fixed using diplopore, it is characterised in that knife
Body uses interior kinking structure, opens up fluted on Sidelong portion, and groove location is corresponding with blade, and Sidelong portion is in the groove opened up
It is welded with blade, Sidelong portion is put relative to blade, and positive cutting blade design triangle cutting edge, can cut off the stubble in soil, cut
Open soil layer；Positive cutting blade is triangle, trapezoidal or inclined-plane, increases the Sliding cutting action of blade；The stubble in soil can be cut off, cuts soil
Layer；In order to better ensure that the enough intensity of blade, reinforcing rib is welded in Sidelong portion lower part along blade both sides.
Preferably：In order to preferably reduce power consumption, improve the work efficiency of product, the penetrating angle α of positive cutting blade for 12 °-
15 °, Overall Power Consumption is preferably minimized at this time, is saved greatly power consumption, so as to save the energy for country.
Compared with prior art, the beneficial effects of the utility model are as follows：It is brand-new cutting invention increases using
Mode, symmetrically makes suitable for the reversal stubble cleaning rotary cultivator cutter shaft both sides that loosing soil is in small, broken bits, weeds in field and other vegetation are less
With so that the power consumption of complete machine is lower, the stability of product is more preferable, being not easily broken, suitable for popularizing in an all-round way and applying.
Brief description of the drawings
Fig. 1 is the utility model side structure schematic diagram；
Fig. 2 is the utility model positive structure schematic.
In figure, 1 tool apron, 2 blades, 3 Sidelong portions, 4 positive cutting blades, 5 cutter shafts.
Embodiment
The following is a combination of the drawings in the embodiments of the present utility model, and the technical scheme in the embodiment of the utility model is carried out
Clearly and completely describe.
As shown in Figure 1 and Figure 2：
A kind of reversal stubble cleaning rotary cultivator biasing is straight to turn over rotary blade, and cutter tool apron 1 is fixed using diplopore, and tool apron 1 is installed on
On cutter shaft 5, blade 2 uses interior kinking structure, opens up on Sidelong portion 3 fluted, and groove location is corresponding with blade 2, and Sidelong portion 3 exists
The groove opened up is welded with blade, and Sidelong portion 3 is put relative to blade 2, and positive 4 design triangle cutting edge of cutting blade, can cut
Stubble in disconnected soil, cuts soil layer；Positive cutting blade 4 is triangle, trapezoidal or inclined-plane, and 3 lower part of Sidelong portion adds along the welding of blade both sides
Strengthening tendons, in order to preferably reduce machine power consumption, the penetrating angle α of positive cutting blade 4 is 12 ° -15 °, and rotary blade is installed on cutter shaft 5,
Machine, machine band movable arbor 5 rotates, and cutter shaft 5 drives rotary blade cutting soil-working.The utility model is mainly used in soil
On the loose soil in small, broken bits, weeds in field of earth.
The above descriptions are merely preferred embodiments of the present invention, is not intended to limit the present invention, although ginseng
The utility model is described in detail according to previous embodiment, for those skilled in the art, it still can be with
Modify to the technical solution described in foregoing embodiments, or equivalent substitution is carried out to which part technical characteristic.It is all
Within the spirit and principles of the present invention, any modification, equivalent replacement, improvement and so on, should be included in this practicality
Within new protection domain.
