Description
Technical field:
The present invention relates to agricultural mechanical field, relates generally to a kind of high stubble returning and fertilizing trench digging high ridge seeding integrated machine.
Background technology:
With the development of mechanization, agricultural machinery development is increasingly as integrative development, such as rotary tillage stubble-cutting machine of the prior art, rotary tillage
Ridger, rotary tillage fertilizer etc., its is convenient and practical, weak point is still suffered from its design, such as rotary tillage stubble-cleaning ditching machine
The rotary blade of middle rotary cultivator is that left and right knife intersects the function that by spiral installation, can only play rotary tillage and the low stubble that goes out, rotary tillage, ridging
Furrowing blade in machine easily twines careless congestion, is not suitable for using when rice high-stubble and more field straw, and rotary tillage fertilizer is only
Can be good in soil moisture content, the low toothing harvesting stalk of rice could use under conditions of crushing uniform shed, and be needed after operation solely
Vertical trench digging, it can not use during soil high humidity ponding, therefore above-mentioned weak point all has much room for improvement.
The content of the invention:
A kind of the defects of the object of the invention is exactly to make up prior art, there is provided high stubble returning and fertilizing trench digging high ridge sowing one
Machine, rotary tillage ridger, no-tillage fertilizing and seeding machine and trapezoidal curved surface ditching plow science are combined, collect rotary tillage stubble-cleaning(High stubble), fertilising,
Trench digging, bedding are seeded in one, and the high cost of operating efficiency is low.
The present invention is achieved by the following technical solutions:
A kind of high stubble returning and fertilizing trench digging high ridge seeding integrated machine, including organic frame, the front upper end of the frame are provided with outstanding
Hanger, the rear of the hanger bracket are provided with seed-fertilizer box, and spaced sowing assembly, institute is distributed with the bottom of the seed-fertilizer box
The front lower end for stating frame is provided with rotary tillage mechanism, and the rotary tillage mechanism includes rotating shaft, and the both ends of the rotating shaft are installed respectively
In frame, rotary blade is distributed with the rotating shaft, it is characterised in that:The rotary blade is two sections of symmetrical structures, and it left half
The rotary blade cutter head on side is consistent to the right, and right half of rotary blade cutter head is consistent to the left, and left half of and right half of rotary blade knife
Head is spirally to be sequentially arranged in rotating shaft, and the rear both sides of the rotary tillage mechanism are separately installed with ditcher mechanism, described to open
Ditch mechanism includes trapezoidal curved surface ditching plow, and trapezoidal curved surface ditching plow is arranged in frame by fixed mount.
Gear-box is installed in the frame below described hanger bracket, the power of the rotary tillage mechanism and sowing assembly by
Gear-box provides.
Power input shaft external part end in described gear-box is provided with the universal joint for connecting power, the tooth
Power output gear in roller box is connected with the driven gear in the middle part of the rotating shaft of rotary tillage mechanism, and one end of the rotating shaft is provided with
Travelling gear, the travelling gear are connected with the gear drive of rotary shaft one end in sowing assembly.
Small plough shovel is installed, the both ends end of the rotating shaft is separately installed with ridging in the middle part of the rotating shaft of described rotary tillage mechanism
Knife.
Described ridging knife includes arc cutter head, and the ridging knife per one end is three, and it is equidistant in order successively
It is distributed on the circumferential position of rotating shaft.
The rear of described rotary tillage mechanism, which is set up, the trailing bar being obliquely installed, and the trailing bar is hung on by hanger bracket
Below frame, and trailing bar is between trapezoidal curved surface ditching plow.
The position height of described trailing bar is adjustable.
The both sides at described frame rear are provided with fixed plate, are provided between the fixed plate and block cover plate.
Its specific principle is:Rotary tillage ridger, no-tillage fertilizing and seeding machine and trapezoidal curved surface ditching plow science are combined, collection
Rotary tillage stubble-cleaning(High stubble), fertilising, trench digging, bedding be seeded in one, the high cost of operating efficiency is low.It is useful under the conditions of different soil moistures content
Wheat cultivation, even in continuous rainy weather, soil ponding extreme soil moisture content under can also realize stubble-cleaning(High stubble), fertilising, trench digging,
Bedding is sowed.The equipment is also applied for the rape high ridge machine sowing under the conditions of various soil moisture contents, its left half of rotary tillage cutter head simultaneously
Unanimously to the right, the first cause of right half of rotary blade to the left, by spiral installation, rotary tillage can be played and gone out high stubble, straw winding not congestion
Effect.It substitutes furrowing blade using trapezoidal curved surface ditching plow, and its trapezoidal curved surface ditching plow expansion is exactly a ladder plane, stubble-cleaning
Slid by curved surface and be not easy to twine grass, can also be automatically drained out even if grass is twined.
It is an advantage of the invention that:
It is of the invention originally reasonable in design, rotary tillage ridger, no-tillage fertilizing and seeding machine and trapezoidal curved surface ditching plow science are combined,
Collect rotary tillage stubble-cleaning(High stubble), fertilising, trench digging, bedding be seeded in one, in rice high stubble harvesting stalk can be stayed not crush and soil
Normal use when earth high humidity ponding, and the high cost of operating efficiency is low, and rotary tillage can be played and gone out high stubble, straw winding
The effect of not congestion.
