The strip seedbed comprises a support, a turning part and a hacking/pressing part, wherein the turning part is arranged at the lower end of the support and used for cutting stubbles and turning and deep loosening the soil; the turning part comprises a deep loosening device and a cutting/turning device arranged at two sides of the deep loosening device; the hacking/pressing part is arranged on the support, positioned at the rear end of the turning part and used for crushing and smoothing soil blocks obtained by turning and deep loosening of the turning part, and finally preparing the soil into strip seedbed zones which are suitable for sowing seeds. The seeder provided with the strip seedbed preparing device, disclosed by the invention, is used for preparing the soil into strip seedbed zones which are suitable for sowing seeds before seeding, and solves the problems of difficulty in driving of a furrower, poor stubble crushing capacity, furrower blockage and poor development and growth of no-tillage planted seeds in the early stage.
Description
Technical field
The present invention relates to a kind of agricultural machinery, relate in particular to the sower that a kind of band shape kind bed that can reorganize and outfit out the kind bed band that is fit to sowing that uses in no-tillage ground is reorganized and outfit device and had this device.
Background technology
China is one of main arid country, and the area of arid, semiarid zone accounts for area 52%.North agricultural arid, short of rain, disaster is frequent, yields poorly and unstable the increasing peasant income difficulty; Turn over makes the farmland exposed every year, and irrational farming makes desertification of land, and wind erosion, water erosion make agricultural lose the ecological balance, have a strong impact on Agricultural Development; Dust and sand weather has a strong impact on the industrial and agricultural production and the people's health.
Agricultural sustainable development is China's Agricultural Development direction, and energy expenditure and water and soil conservation will force conservation tillage to become a kind of main cropping system.
The development conservation tillage is the important measures of administering farmland airborne dust, the wind erosion of control farmland and water erosion; the development conservation tillage is culture fertility, the main means that promote agricultural sustainable development; the development conservation tillage is the effective way that reduces agriculture production cost, improves productivity effect, and the development conservation tillage is the major action that prevents and treats crop straw burning, reduces greenhouse gas emission.Organic unity ecological, economic and social benefit that protective farming technique has been realized; resources conservation, recycling and environmental protection are mutually promoted; when developping production; improved ecotope; realized harmonious co-existence between man and nature, harmonious development, embodied and adhered to the Scientific Outlook on Development and the fundamental requirement of building a harmonious society.The development conservation tillage for protecting farmland, improves environment, promotes agricultural sustainable development, ensures national food safety, has crucial meaning.
The key of protective farming technique application success is to have suitable no-tillage seeding machinery, and existing no-tillage seeding machine exists: since the face of land covered a large amount of stubbles and stalk cause seed-furrow opener to stop up to cause the seedling problem of breaking, the face of land hard cause plough bury difficult problem and no-tillage seeding seed owing to the hard seedling of geology in the bad problem of early growth period development growth.The no-tillage seeding machine that addresses this problem is at present mainly set about from anti-blocking plough of breaking and grass divider etc., and result of use has certain improvement but can not fundamentally solve the problem that no-tillage seeding machine exists.China's utility model patent " 98218324.0 ", " the banded anti-block apparatus of pulverizing of no-tillage seeding machine " discloses a kind of banded anti-block apparatus of pulverizing, this device is installed in the plough front by power take-off and is driven the rotation of cutter shaft high-speed reverse, cut off covering by composite blade, and prevent to stop up by the matching relationship of composite blade and plough.Though solved the anti-blocking problem of no-tillage seeding machine, power consumption is big, efficient is low, is not suitable for the wide cut operation.
