Feeding mechanism for cotton straw harvesting and harvester comprising feeding mechanism

Abstract

The invention discloses a feeding mechanism for cotton straw harvesting and a harvester comprising the feeding mechanism. The feeding mechanism comprises a frame, two auxiliary feeding rollers, two front feeding rollers and a rear feeding roller are mounted on the frame, and the auxiliary feeding rollers, the front feeding rollers and the rear feeding roller are parallel one another in axis; eachauxiliary feeding roller includes a dial shaft, one end of the dial shaft is connected with a transmission device while the other end is provided with three layers of dials thereon, each dial is provided with multiple pulling teeth, and the pulling teeth located on the dials of the upper and lower layers are bent pulling teeth opposite in bending direction; the pulling teeth of the dial located inthe intermediate layer is straight pulling teeth; the front feeding rollers are located in the rear of the auxiliary feeding rollers and in back and front correspondence to the auxiliary feeding rollers, and the corresponding front feeding rollers and auxiliary feeding rollers rotate are driven by a transmission chain to rotate in the opposite direction; the rear feeding roller is located in therear of the front feeding rollers and rotates anticlockwise.

Description

technical field [0001] The invention discloses a feeding mechanism for mechanized harvesting of cotton stalks and a harvester comprising the mechanism. Background technique [0002] Cotton stalk is an important straw resource with a wide range of uses. Harvesting cotton stalks is the advance of comprehensive utilization of cotton stalks, and mechanized harvesting is the fundamental way to solve the problem of labor-intensive and low-efficiency cotton stalk harvesting. The transportation of cotton stalks is one of the difficulties restricting the mechanized harvesting of cotton stalks. The characteristics of cotton stalks with many branches and hard wood make the transportation difficult and the transportation effect is poor. [0003] The existing cotton stalk feeding mechanisms are basically modified by wheat and corn stalk feeding mechanisms. When the cotton stalk harvester using these feeding mechanisms works, the straw feeding mechanism is prone to the phenomenon that th...

AI Technical Summary

Problems solved by technology

Cotton straw has many branches, high hardness and toughness, and the shape and properties of the straw are very different from those of wheat and corn, which increases the difficulty of transportation. Therefore, the straw feeding mechanism used for wheat and corn is obviously not suitable for cotton straw transportation. There are few studies on the special feeding mechanism for cotton stalks
