Inter-cultivation weeding mechanism for inter-cultivation machinery with combined compound operation

Abstract

The invention provides an in-row weeding mechanism of a cultivator for combined composite work, and belongs to the field of agricultural machine. Parallel rear suspension shafts are mounted, at rear positions of a main suspension shaft, on a frame assembly, a rear weeding tooth-roller assembly composed of tandem rear weeding fluted discs are rotatingly assembled on the rear suspension shafts, the rear weeding tooth-roller assembly are arranged at the right behind position of a main weeding tooth-roller assembly, and a rear weeding fluted disc of the rear weeding tooth-roller assembly and a main weeding fluted disc of the main weeding tooth-roller are interlaced. When the in-row weeding mechanism is used for firstly weeding before crops sprout and after the crops sprout, both of rotational linear velocities of the main weeding fluted disc and the rear weeding fluted disc are 3.3 to 9.8 m / sec. When the in-row weeding mechanism is used for secondly weeding after the crops sprout, the rotational linear velocities of the main weeding fluted disc is 3.3 to 9.8 m / sec, and the rotational linear velocity of the rear weeding fluted disc is lower than that of the main weeding fluted disc. The in-row weeding mechanism is high in weeding efficiency and low in sprout damage rate, so the in-row weeding mechanism can be used for weeding before and after crops sprout.

Description

technical field [0001] The invention belongs to agricultural machinery, and mainly relates to a mechanism for weeding between seedlings with mechanical joint compound operations. Background technique [0002] The mechanical cultivator and weeder is a weeding machine that appeared in the 1960s and 1970s. Due to the use of weeding teeth without accurate positions, irregularities, and no speed requirements, it is completed by mechanically picking up crop seedlings and various grass seedlings. The so-called "weeding" operation, so when this type of machine came out, it was commonly known as "blind pulling". In recent years, with the development requirements of green organic agriculture, in order to produce more green organic agricultural products, Heilongjiang Province has begun to promote the "three reductions" agronomic requirements in a large area, that is, reducing chemical fertilizers, reducing pesticides and reducing weeding dosage of the agent. Therefore, how to greatly...

Problems solved by technology

However, from the 1960s and 1970s to the present, all mechanical intertillage weeding machines have adopted a single weeding tooth roller or weeding disc structure, that is, only one weeding operation can be performed on the seedlings during one walk in the field, not only weeding The operation effect is poor, and the operation efficiency is low, the weeding operation cycle is long, and the operation cost is increased
