Description
Technical field
The present invention relates to a kind of sower, relate in particular to a kind of stalk returning field no-tillage fertilizing and seeding machine.
Background technology
Straw-returning has following benefit, and 1, increase the soil organic matter, getting fat soil fertility; 2, form organic covering, drought-relief; 3, reduce the incidence of damage by disease and insect; 4, the saving of labor increases production, fights for farming season; 5, improve soil environment, improve the low and medium-yield farmland; 6, optimize the environment, prevent and remedy pollution.
The operating cost of mechanization straw-returning is merely 1/4 of artificial also field; Every mu of 25-35 unit, and the comparable manual work of work efficiency also the field is high 40～120 times, but also increasing both production and income; Therefore, the mechanization straw-returning is the effective way that large tracts of land realizes increasing soil fertility, setting up with ground the stable high yield farmland; The mechanization straw-returning is fully utilized the organic matter in the stalk, has avoided peasant a large amount of crop straw burnings for a long time and the environmental pollution that causes, helps the ecological agriculture and environmental protection Agricultural Development.But there is following problem in existing straw-returning equipment, one, the crushed stalk weak effect, and the not perishable organic manure that changes into behind the straw-returning; Two, because the straw-returning effect is good inadequately, influence sowing and fertilising, seedling and evaporation of water in soil race fertilizer are burnt in heating to be prone to that stalk combines with soil seed, stalk rots; Three, straw-returning, rotary tillage sowing separately waste energy and the time, and rotary tillage simultaneously produces destruction to soil structure and edaphon.
Summary of the invention
In order to solve the problems of the prior art, the purpose of this invention is to provide a kind of crushed stalk thoroughly, need not rotary tillage, save time, laborsaving, economize kind, synergy is in the stalk returning field no-tillage fertilizing and seeding machine of one.
For achieving the above object; The technological means of employing according to the invention is: stalk returning field no-tillage fertilizing and seeding machine; Comprise suspension arrangement, variable transmission mechanism, frame, one-level cutter shaft, secondary cutter shaft, pack roller, ferti-seeding assembly; Said suspension arrangement is installed on the frame, and said variable transmission mechanism is installed on the frame, is positioned at the suspension arrangement below; Said one-level cutter shaft is installed in the frame inner chamber, and its power transmission shaft is connected with variable transmission mechanism, and the one-level cutter shaft is provided with chevron shaped cutting knife; Said secondary cutter shaft is installed in the frame inner chamber, is positioned at level behind the one-level cutter shaft, and its power transmission shaft connects variable transmission mechanism, and the secondary cutter shaft is provided with chevron shaped cutting knife, and said chevron shaped cutting knife is staggered complementation on the distributing position on the secondary cutter shaft and one-level cutter shaft; Said ferti-seeding assembly is installed on the frame, is positioned at level behind the secondary cutter shaft; Said pack roller is installed on the frame, is positioned at level behind the ferti-seeding assembly, and the pack roller output shaft is through the ferti-seeding assembly that is in transmission connection.
Further, said ferti-seeding assembly comprises seed manure case, seeds discharging box, seeding flexible pipe, grain tube, defertilizing box, fertilizer flexible pipe, fertilizer delivering pipe, and said seeds discharging box connects the seed manure case, and the seeding flexible pipe is positioned under the seeds discharging box, and grain tube connects the seeding flexible pipe; Said defertilizing box connects the seed manure case, and the fertilizer flexible pipe is positioned under the defertilizing box, and fertilizer delivering pipe connects the fertilizer flexible pipe; Said fertilizer delivering pipe is preceding, grain tube after, be connected to form a defeated fertile kind group through the U sprig, said defeated fertile kind group is provided with two rows altogether, and is staggered between the front and rear row.
Further, chevron shaped cutting knife that is provided with on said one-level cutter shaft and the secondary cutter shaft and cutter shaft be connected to movable pin joint, be provided with upright cutter in the corresponding chevron shaped edge of a knife of frame centre position.
Further, said ferti-seeding assembly also comprises kind of amount regulating handle and fertile amount regulating handle, and said kind amount regulating handle connects seeds discharging box, and said fertile amount regulating handle connects defertilizing box.
Beneficial effect of the present invention is: stalk rots to be converted into the high-quality fertilizer material more easily through twice pulverizing; Ferti-seeding carries out under the environment of no stalk, and seed intimately combines with soil, the problem that stalk combines with soil seed, seedling is burnt in the rotten heating of stalk and the evaporation of water in soil runs fertilizer can not occur, and effect of increasing production is obvious; Straw-returning, no-tillage fertilizing sowing are once accomplished, and have not only practiced thrift the energy and time, and the while is no-tillage has avoided the destruction of rotary tillage to soil structure and edaphon; The stalk of pulverizing is tiled in and has formed natural ground membrane environment on the soil, has soil moisture conservation, and seedling-protection hardens and soil erosion after rainproof; Directly pulverize sowing in the dark stub land after machine is received, save time, laborsaving, economize plant, synergy, avoided because of problems such as atmospheric pollution that crop straw burning causes, environmental destructions.
