The edge of the fixed cutter is provided with a groove. The cutting edge of the disk cutter extends into the groove, and a gap is reserved between the cutting edge of the disk cutter and the bottom of the groove.
Description
Technical field
The present invention relates to a kind of stubble remover for no-tillage seeding machine, belong to farm machinery technical field.
Background technology
Yellow-huai river basin is China winter wheat and summer soybean main producing region, and wherein, wheat cultivation area exceedes 2/3rds of the national wheat gross area, and soybean planting area accounts for 1/4th of the national soybean gross area.This area soybean is sowing after winter wheat results generally.Because wheat straw amount in field after wheat harvest is large, combine pulverizes wheat straw power consumption greatly when wheat harvest operation, be difficult to pulverized completely by wheat straw and evenly shed it to field, after causing wheat harvest, toothing is higher, generally reaches 30-40 centimetre; During the second stubble crops such as the wheat straw that reaping machine is shed after pulverizing also is scattered in earth's surface brokenly, soybean sowing, seeding unit is difficult to pass through smoothly, often causes sower to block, has a strong impact on seeding quality, and delay farming season, affect output.Current, in the Soybean production of Huang-Huai-Hai ubiquity be short of seedling disconnected ridge, yield poorly, problem of poor benefits, have a strong impact on the kind beans enthusiasm of peasant.The traditional method addressed this problem burns wheat stubble, finally reach cleaning field wheat straw, realize the object of sower normal operation, but burn wheat straw and cause serious air pollution and organic loss, with current national administer air pollution and develop eco-agriculture theory Serious conflicts.
The crop of front stubble stalk process problem beyond other area, the whole nation and soybean as corn, peanut production in also extensively exist, therefore, realize former stubble no-tillage seeding and China's grain, cotton and oil increasing both production and income and agriculture sustainable development be significant.
Summary of the invention
For the problems referred to above, the object of this invention is to provide a kind of stubble remover for no-tillage seeding machine, this stubble remover can be arranged on existing sower thus to enable sower realize no-tillage seeding.
For achieving the above object, the present invention takes following technical scheme: a kind of stubble remover for no-tillage seeding machine, it is characterized in that: it comprises a support, the upper end of described support is connected with the frame of sower, the lower end of described support is rotationally connected a rotating shaft by a bearing, the described rotating shaft being positioned at described support side is fastenedly connected a disc cutter, the rotating shaft being positioned at described support opposite side is fastenedly connected a sprocket wheel, at the even hinged multipair hammer leaf with cutting edge of the circumference of described disc cutter, described in every a pair, hammer leaf is all positioned at the both sides of described disc cutter, a stationary knife is fixedly connected with to the side of described disc cutter by a stationary knife bearing at described stent cover, described stationary knife near described disc cutter cutting edge and described in a pair between hammer leaf.
The edge of described stationary knife is provided with groove, and the cutting edge of described disc cutter to stretch in described groove and leaves gap with the bottom of described groove.
The present invention is owing to taking above technical scheme, it has the following advantages: 1, the present invention arranges a multiple disc cutter, at the even hinged multipair hammer leaf with cutting edge of the circumference of each disc cutter, under the influence of centrifugal force, hammer leaf can interrupt or cut off former stubble fast, and the stone on earth's surface and hard object also can be chosen out by the hammer leaf rotated, and avoid causing cutting edge to damage because of rigid impact cutting during disc cutter High Rotation Speed, extend service time of the present invention.2, the present invention is owing to arranging a multiple stationary knife, the edge of each stationary knife is provided with groove, the former stubble do not interrupted by hammer leaf and cut off will be driven by hammer leaf and rotate up, when it contacts with stationary knife, cut off at hammer leaf rapidly with under the cooperation of disc cutter with stationary knife and stationary knife groove, improved service efficiency of the present invention.

Embodiment
Below in conjunction with drawings and Examples, the present invention is described in detail.
As shown in Fig. 1 ~ 2, the present invention includes a support 1, the upper end of support 1 is connected with the frame of sower, the lower end of support 1 is rotationally connected a rotating shaft 3 by a bearing 2, the rotating shaft 3 being positioned at support 1 side is fastenedly connected a disc cutter 4, the rotating shaft 3 being positioned at support 1 opposite side is fastenedly connected a sprocket wheel 5.At the even hinged multipair hammer leaf 6 with cutting edge of the circumference of disc cutter 4, every a pair hammer leaf 6 is all positioned at the both sides of disc cutter 4.Be fixedly connected with a stationary knife 8 towards the side of disc cutter 4 by a stationary knife bearing 7 at support 1, stationary knife 8 near disc cutter 4 cutting edge and between a pair hammer leaf 6.
In above-described embodiment, further, as shown in Figure 3, the edge of stationary knife 8 is provided with groove 9, and the cutting edge of disc cutter 4 to stretch in groove 9 and leaves gap with the bottom of groove 9.
The present invention in use, is connected with the frame of sower by support 1, and sprocket wheel 5 is by a chain connecting drive device simultaneously.When sower is advanced forward, open drive unit, it drives disc cutter 4 reverse (reverse with sower wheel) to rotate by sprocket wheel 5.Hammer leaf 6 stretches out disc cutter 4 under the influence of centrifugal force, under the drive of the disc cutter 4 of High Rotation Speed, interrupt or cut off former stubble.Will do not driven by hammer leaf 6 by the former stubble that hammer leaf 6 interrupts and cuts off and rotate up, when it contacts with stationary knife 8, by cut-off under the cooperation of hammer leaf 6 with stationary knife 8.In addition, the stone on earth's surface and hard object also can be chosen out by the hammer leaf 6 of rotation, avoid causing cutting edge to damage because of rigid impact cutting during disc cutter 4 High Rotation Speed.
In order to reach better breaking effect, can be arranged on sower by multiple stubble remover of the present invention, each stubble remover be disposed in parallel in a row, also can be arranged to two rows, is principle with non-interference simultaneously.
The various embodiments described above are only for illustration of the present invention, and wherein the structure, connected mode etc. of each parts all can change to some extent, and every equivalents of carrying out on the basis of technical solution of the present invention and improvement, all should not get rid of outside protection scope of the present invention.
