Description
Technical field
The present invention relates to a kind of stubble remover for no-tillage seeding machine, belong to agricultural machinery and implement 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 whole nation Semen Tritici aestivi gross area, and soybean planting area accounts for 1/4th of the whole nation Semen sojae atricolor gross area.This area Semen sojae atricolor is sowed after being typically in winter wheat results.Owing to after wheat harvest, wheat straw amount in field is big, it is big that wheat straw power consumption pulverized by united reaper when wheat harvest operation, it is difficult to being pulverized completely by wheat straw and uniformly shed it to field, after causing wheat harvest, toothing is higher, commonly reaches 30-40 centimetre；During the second stubble crops such as the wheat straw that cropper is shed after pulverizing also is scattered in earth's surface brokenly, Semen sojae atricolor sowing, feed mechanism for seed is difficult to pass through, and often results in seeder blocking, has a strong impact on seeding quality, and delay farming season, affect yield.Currently, 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 bean enthusiasm of peasant.The traditional method solving this problem is that wheat stubble is burned, it is finally reached cleaning field wheat straw, realizes the purpose of seeder 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.
Front stubble straw processes in problem crop such as Semen Maydis, peanut production beyond other area, the whole nation and Semen sojae atricolor and is also widely present, therefore, it is achieved the sustainable development of China's grain, cotton and oil increasing both production and income and agricultural is significant by former stubble no-tillage seeding.
Summary of the invention
For the problems referred to above, it is an object of the invention to provide a kind of stubble remover for no-tillage seeding machine, this stubble remover may be mounted on existing seeder so that seeder is capable of no-tillage seeding.
For achieving the above object, the present invention takes techniques below scheme: a kind of stubble remover for no-tillage seeding machine, it is characterized in that: it includes a support, the upper end of described support is connected with the frame of seeder, 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, the uniform hinged multipair hammer leaf with cutting edge of circumference at described disc cutter, hammer leaf described in every a pair is respectively positioned on the both sides of described disc cutter, a stationary knife is connected towards the side of described disc cutter by a stationary knife bearing is fixing at described support, described stationary knife is near the cutting edge of described disc cutter 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 stretches in described groove and leaves gap with the bottom of described groove.
Due to the fact that and take above technical scheme, it has the advantage that 1, the present invention arranges a multiple disc cutter, the uniform hinged multipair hammer leaf with cutting edge of circumference at each disc cutter, under the influence of centrifugal force, hammer leaf can quickly interrupt or cut off former stubble, and rotate hammer leaf can also by the stone on earth's surface and hard thing teasing, it is to avoid cause cutting edge to damage because of rigid impact cutting during disc cutter high speed rotating, prolongation the present invention the use time.2, due to the fact that a multiple stationary knife is set, the edge of each stationary knife is provided with groove, the former stubble not interrupted by hammer leaf and cut off will be driven by hammer leaf and rotate up, when it contacts with stationary knife, to be quickly shut off with under the cooperation of disc cutter with stationary knife and stationary knife groove at hammer leaf, improved the service efficiency of the present invention.

Detailed description of the invention
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 seeder, 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.The uniform hinged multipair hammer leaf 6 with cutting edge of circumference at disc cutter 4, every a pair hammer leaf 6 is respectively positioned on the both sides of disc cutter 4.Connecting a stationary knife 8 towards the side of disc cutter 4 by a stationary knife bearing 7 is fixing at support 1, stationary knife 8 is near the cutting edge of disc cutter 4 and between a pair hammer leaf 6.
In above-described embodiment, further, as it is shown on figure 3, the edge of stationary knife 8 is provided with groove 9, the cutting edge of disc cutter 4 stretches in groove 9 and leaves gap with the bottom of groove 9.
The present invention in use, is connected with the frame of seeder by support 1, and sprocket wheel 5 connects driving device by a chain simultaneously.When seeder is advanced forward, opening driving device, it drives disc cutter 4 reverse (reverse with seeder wheel) to rotate by sprocket wheel 5.Hammer leaf 6 stretches out disc cutter 4 under the influence of centrifugal force, interrupts or cut off former stubble under the drive of the disc cutter 4 of high speed rotating.The former stubble not interrupted by hammer leaf 6 and cutting off will be driven by hammer leaf 6 and rotate up, when it contacts with stationary knife 8, by cut-off with under the cooperation of stationary knife 8 at hammer leaf 6.Additionally, the hammer leaf 6 rotated can also by the stone on earth's surface and hard thing teasing, it is to avoid cause cutting edge to damage because of rigid impact cutting during disc cutter 4 high speed rotating.
In order to reach better breaking effect, it is possible to being arranged on seeder by multiple stubble removers of the present invention, each stubble remover is disposed in parallel in a row, it is also possible to be arranged to two rows simultaneously, with non-interference for principle.
The various embodiments described above are merely to illustrate the present invention, and wherein the structure of each parts, connected mode etc. all can be varied from, every equivalents carried 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.
