Cotton picking roller assembly with picking spindles capable of backwardly and forwardly rotating

Abstract

The invention relates to a cotton picking roller assembly with picking spindles capable of backwardly and forwardly rotating and belongs to the technical field of cotton harvesting machinery. Problems of complicate structures, great manufacturing and use cost and high impurity content of a cotton picking roller in the prior art can be solved. The cotton picking roller assembly is characterized by comprising a cotton picking roller formed by N picking spindle seat tubes and a plurality of picking spindles, wherein the axis of each picking spindle seat tube is parallel or generally parallel to the axis of the cotton picking roller; the axis of each picking spindle is parallel or generally parallel to the vertical surface of the axis of each picking spindle seat tube; the picking spindles are rotationally supported by the picking spindle seat tubes; seat tube belt wheels with the same specifications and for driving are arranged in the same positions of the shaft ends of the N picking spindle seat tubes; two auxiliary belt wheel sets are fixed close to a revolution track of each seat tube; transmission belts of the two auxiliary belt wheel sets are both double-faced; and rotation directions of the transmission belts are opposite. The cotton picking roller assembly is advantaged by simple structure, capability of the use of long picking spindles and great impurity rate reduction; and the cotton picking roller assembly with picking spindles capable of backwardly and forwardly rotating is mainly provided.

Description

technical field [0001] The invention belongs to the technical field of cotton harvesting machinery, and in particular relates to a forward and reverse cotton picking cylinder assembly for picking spindles. Background technique [0002] Cotton is harvested with a spindle-type picking drum, and the action of picking cotton is roughly the same. That is to use the rotating picking spindle to grab part of the cotton fibers first, then pull out the whole cotton and wind it on the picking spindle, and then bring the cotton to the cotton withdrawal area to return. The action of picking cotton determines that it is not easy to remove cotton. For example, the horizontal cotton picker represented by Deere and Case in the United States uses the speed difference between the cotton doffer and the conical picking spindle to quickly pull the cotton down. , this method is mature and reliable, but it has high requirements on the manufacturing precision and matching precision of the associate...

Problems solved by technology

The action of picking cotton determines that it is not easy to remove cotton. For example, the horizontal cotton picker represented by American Deere and Case uses the speed difference between the cotton doffer and the conical picking spindle to quickly pull the cotton down. , this method is mature and reliable, but it has high requirements on the manufacturing precision and matching precision of related components, and is highly dependent on auxiliary facilities such as cleaning, cooling, and lubrication, so the production of the cotton picking drum unit is very complicated and the manufacturing cost In addition, this kind of horizontal cotton picking cylinder has a great influence on the quality of cotton. The high-speed hard-drawn cotton withdrawal method determines that the length of the picking spindle is limited. If it is too long, it will fall off due to angle and stroke problems. If the cotton is not lost, the short picking spindle requires that the cotton plant should be compressed as much as possible. Compression helps to improve the harvesting rate, but at the same time increases the probability of cotton flowers being entangled with impurities
