Description

Header of vertical roller corn harvester

technical field

The invention belongs to the technical field of agricultural machinery design and manufacture, and in particular relates to a header of a vertical roller corn harvester.

Background technique

In recent years, with the continuous increase of the country's investment in agricultural production, the degree of mechanization of corn production in my country has continued to increase, but corn harvesting is still the "bottleneck" that restricts the mechanization of the whole process of corn production. Poor adaptability is the main reason for the slow development of corn harvesting machinery.

The ear picking part is the core part of the corn harvester. Corn harvester headers are divided into ear picking roller type and ear picking plate type according to the ear picking form, and ear picking roller headers are further divided into horizontal roller type and vertical roller type headers. The adaptability and working reliability of the vertical roller type is not as good as that of the horizontal roller type, but the vertical roller type has advantages in straw recovery and less grain loss, and is more suitable for the northeast and southwestern regions where the whole corn stalk needs to be recycled. Therefore, , the research on the vertical roller header is very meaningful. Due to the relatively little research on the vertical roller ear picking mechanism at home and abroad, there is no evidence for its structural type, motion parameters, etc. However, the lack of basic support such as theory and experiments has brought many problems to the design and production of vertical roller corn harvesters.

Vertical ear picking roller corn harvester refers to the corn harvester configured with the angle between the ear picking roller and the horizontal greater than 60°. , into the relatively rotating picking roller, and the ear of corn is picked off under extrusion and impact. The fallen ears are sent to the ear box (or peeling device) by the elevator, and the straw is crushed and returned to the field by the processing device or chopped up for recycling or placed as a whole plant. The advantages of the vertical roller corn harvester are: the harvesting loss is small, and the straw is easy to handle. Because the picking rollers of the vertical ear picking roller type corn harvester are tilted forward, the ears fall into the elevator immediately after being picked, and there is no rolling process, so the falling grains are less. Due to the wide space behind the vertical ear picking roller, different straw processing parts can be configured. The crushing and returning parts can be installed to realize straw crushing and returning to the field, and the cutting and throwing parts can be installed to realize section recovery, and the laying parts can be installed. Just can realize whole straw recycling.

The header of the vertical roller corn harvester is mainly composed of ear picking and stem pulling rollers, clamping and conveying devices, grain dividers and cutters. Most of the existing domestic vertical roller corn harvesters are equipped with a pair of ear picking rollers. The cover clamps the conveying device and the grain divider. The harvesting row spacing is determined by the grain dividing width of the grain divider. The adaptability of the row spacing of the header is poor, which hinders the development of the vertical roller header. The present invention starts with the overall structure of the header, researches and designs a novel vertical roller type header, which consists of a pair of ear picking rollers, two sets of clamping and conveying devices, two sets of grain dividers, two sets of cutters and The two sets of clamping and conveying devices significantly increase the harvesting width, and the width of the grain division is adjustable, which improves the row spacing adaptability of corn harvesting in different regions and different planting techniques.
