Cutting device of a corn harvester

Abstract

The invention discloses a cutting and conveying device of a corn harvester. The cutting and conveying device comprises a stalk distributing device, a stalk cutting device and a conveying device, wherein the conveying device comprises a conveying belt; the stalk cutting device is connected with the front end of the conveying belt and comprises a pair of conical spiral cutting and conveying devices symmetrically arranged along the central axis of the conveying belt; each conical spiral cutting and conveying device comprises a vertical rod, a frustum, a cutting knife and arc-shaped kick-off teeth, each frustum is installed at the bottom of each vertical rod, and each cutting knife is arranged at the bottom of each frustum; a rotary boss in a spiral shape from the bottom to the top is arranged on the outer side surface of each frustum, and a plurality of arc-shaped kick-off teeth are installed on each rotary boss; and the stalk distributing device comprises a pair of gathering frames and a pair of dividers. The cutting and conveying device has the characteristics of simple structure and convenience, rapidness and high efficiency in cutting and conveying.

Description

technical field [0001] The invention relates to a matching mechanism of agricultural machinery, in particular to a cutting device of a corn harvester. Background technique [0002] Most of the existing corn plantings choose different planting row spacings according to the width of their own fields, corn varieties, geology, climate, water conservancy conditions, etc., and the row spacing ranges from 400-800mm. Due to the large difference between the row spacing of planting corn and the center distance between the two sets of ear picking rollers of the corn harvesting machine, the corn lodging brings great difficulty to the mechanical harvesting of corn, which greatly reduces the harvesting quality and efficiency, and even cannot be harvested; in addition, A large number of corn stalks are piled up and burned in the field after harvesting, which not only pollutes the environment, but also causes a waste of resources; moreover, the temperature is low in autumn, there is a lot o...

Problems solved by technology

Due to the large difference between the row spacing of planting corn and the center distance between the two sets of ear picking rollers of the corn harvesting machine, the corn lodging brings great difficulty to the mechanical harvesting of corn, which greatly reduces the harvesting quality and efficiency, and even cannot be harvested; in addition, A large number of corn stalks are piled up and burned in the field after harvesting, which not only pollutes the environment, but also causes waste of resources; moreover, the temperature in autumn is low, there is a lot of rain, and the time to recycle corn is tight. The existing mechanical devices cannot meet the needs of agricultural machinery operators.
