Abstract

The invention relates to a uniset for mechanical soil-loosening and weeding of crop seedling belts, belonging to agricultural machinery. A transmission assembly and a connecting frame are mounted on a uniset frame assembly, a driving box assembly is assembled on the lower side part of the connecting frame, a driven bevel gear and a power output chain wheel are respectively and fixedly mounted on a power input shaft and a power output shaft of the transmission assembly, a driving bevel gear and a drive chain wheel are coaxially mounted on the uniset frame assembly, a first drive chain is sleeved on the drive chain wheel, a power input chain wheel, a driving cylindrical gear and a driven cylindrical gear are assembled on the driving box assembly, a second drive chain is sleeved on the poweroutput chain wheel and the power input chain wheel, an eccentric wheel assembly with an elastic weeding tooth assembly is assembled on a front power output shaft and a rear power output shaft of the driving box assembly and the single frame assembly is connected and mounted on a stand assembly through a parallel four-bar mechanism. The invention has favorable operation quality, low seedling-damaging rate, wide application range and stable operation.

Description

technical field [0001] The invention belongs to agricultural machinery, and mainly relates to an operation assembly on a cultivating and weeding machine. Background technique [0002] In the process of agricultural production, cultivating crops such as corn, soybeans, cereals, and cotton is a very important operation link such as soil loosening and weeding. Although chemical agents are highly efficient and quick to kill weeds, the negative effects brought about by long-term use have attracted people's attention: polluting the environment, endangering the survival of humans and animals, and weeds developing drug resistance. Mechanized soil loosening and weeding operations do not pollute the environment, and also have a better effect of loosening soil and preserving moisture. At present, the domestically used working parts for weeding the seedling strips mainly include rotary comb type, hoe tooth type and horizontal disc type. The structure is simple, but there are problems: ...
