But up to now from the 60 to 70's of last century, all mechanical intertillage Weeder for seedling are all made of single weeding discaling roll Or weeding dish structure, that is, go to the field a walking process can only between a weeding operation is carried out seedling, not only weeding operation effectiveness it is poor, And operating efficiency is low, and weeding is long duty cycle, and operating cost improves.

Summary of the invention

The purpose of the invention is aiming at above-mentioned traditional problem of the existing technology, the organic agricultural production of combining with green The actual needs of product production development is researched and developed a kind of cultivating tillage equipment Weeder for seedling structure of the joint multiple operation of new construction, is reached Increase substantially mechanical weeding operation quality and effect, raising operating efficiency, reduction herbicide usage amount, guarantee between intertilling seedling The purpose of green agriculture production.

The purpose of the invention is achieved in that a kind of cultivating tillage equipment Weeder for seedling structure packet for combining multiple operation Including rack assembly and the main hanging axis being mounted on support assembly are rotatably equipped with by main weeding tooth on the main hanging axis The main weeding discaling roll assembly that disk composes in series is parallel to each other on the support assembly, at main hanging axis rear position Axis is hung after installation, and it is total that the rear weeding discaling roll for being rotatably equipped on axis and being composed in series by rear weeding fluted disc is hung after described At the rear weeding discaling roll assembly is integrally located at the dead astern of main weeding discaling roll assembly, and on the rear weeding discaling roll assembly The main weeding fluted disc on weeding fluted disc and main weeding discaling roll assembly is on the lateral position of left and right in the dislocation configuration that intersects afterwards；? Crops do not emerge before seedling between weeding operation when, linear speed is turned round at the tooth tip position of the main weeding fluted disc and rear weeding fluted disc Degree is 3.3-9.8 meter per second；Between the first time seedling after crops emergence when weeding operation, at main weeding fluted disc tooth tip position It is 3.3-9.8 meter per second with the revolution linear velocity at rear weeding fluted disc tooth tip position, between second of seedling after crops emergence When weeding operation, the revolution linear velocity at main weeding fluted disc tooth tip is 3.3-9.8 meter per second, the revolution at rear weeding fluted disc tooth tip Linear velocity is lower than the revolution linear velocity at main weeding fluted disc tooth tip.

The research method that the applicant combines according to agricultural machinery with agronomy, studied successfully first " crops emergence it is forward and backward Mechanical weeding soil-loosening machine uses agricultural method ", and in having declared application for a patent for invention a few days ago.Now depending on this method, and grind Sent out joint multiple operation cultivating tillage equipment Weeder for seedling structure, once go to the field in operation between same a line seedling twice in succession with two The different revolution linear velocity of a weeding fluted disc carries out the weeding of seedling room machine, the reasonable, mechanism structure with operation agronomy process engineering Novelty is simple, technical parameter is determining accurately, can meet weeding operation requirement, weeding rate that various crops emerge forward and backward Feature high, seedling-damaging ratio is low uses to reduce herbicide, production green organic farm products provide equipment and support.
