Combined vertical comb-type weeding mechanism for crop seedling with loose soil

Abstract

The invention relates to a combined vertical comb-type weeding mechanism for crop seedlings with loose soil, which belongs to agricultural machinery. In the technical scheme, a transmission case is provided with a rear power output shaft and a front power output shaft in parallel, the rear power output shaft is provided with a driving sprocket and a driving cylindrical gear, the front power output shaft is provided with a driven cylindrical gear, the outer ends of the front power output shaft and the rear power output shaft are fixedly provided with a comb-type shaft with elastic comb teeth respectively through a flange coupling plate, a circular chute is arranged on outer side faces of the front wall and the back wall of the transmission case, a driven plate is arranged on the circular chute, a pin shaft is arranged on the driven plate, and the two ends of a connecting plate are fixedly connected with the comb-type shaft and the pin shaft respectively. The mechanism can make the elastic comb teeth on the comb-type shaft always maintain the upright state during the operation, has the advantages of novel and reasonable structure, stable insertion of the elastic comb teeth in the soil, high operating quality, high efficiency, low rate of injured seedlings and high adaptability, and can be widely applied in inter-tillage of soybeans, corns, beets, cereals, cotton and other crops.

Description

technical field [0001] The invention belongs to agricultural machinery, and mainly relates to a seedling band loosening and weeding operation mechanism on a mechanical cultivating and weeding machine tool. 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. Because mechanized soil loosening and weeding does not pollute the environment, it also has a good soil moisture conservation effect. For this reason, mechanical weeding is widely used in the agricultural production process in northern my country. At present, the domestically used working parts for weeding the seedling strips mainly include the rotary comb type, the hoe tooth type and the horizontal disc type. The problem is that the movement trajectory of the weeding teeth is unreasonable, the ability of the weeding teeth to penetrate the soil is poor, the soil is pick...

AI Technical Summary

Problems solved by technology

At present, the domestically used working parts for weeding the seedling strips mainly include the rotary comb type, the hoe tooth type and the horizontal disc type. The problem is that the trajectory of the weeding teeth is unreasonable, the ability of the weeding teeth to penetrate the soil is poor, the soil is picked up, the seedlings are entangled, and the weeding parts are poor in stability and adaptability.
