Multifunctional test bench for plucking chain type sunflower header test

Abstract

The invention relates to a multifunctional test bench for a plucking chain type sunflower header test. The multifunctional test bench for the plucking chain type sunflower header test comprises a feeding mechanism, dividing mechanisms, a plucking mechanism, a cutting mechanism, a conveying mechanism and a controller, wherein the feeding mechanism is used for driving plant fixing devices to move and then conveying plants to the cutting mechanism, the plant fixing devices are used for placing the plants, wherein the spacing between adjacent plant fixing devices can be adjusted; the dividing mechanism are arranged in parallel one another at equal intervals and the spacing between adjacent dividing mechanisms can be adjusted, and both the positions of the cutting mechanism and the conveying mechanism can be adjusted; the controller is used for controlling and storing the speeds of the feeding mechanism and the plucking mechanism and the speed and the torque of the cutting mechanism. The multifunctional test bench for the plucking chain type sunflower header test disclosed by the invention can simulate harvesting for the plants with different row spacings and tests influence of the speeds of the plucking mechanism, the cutting mechanism and the conveying mechanism on the harvesting effect, the spacing of two cutters on the harvesting effect and the positions of the cutters and theconveying mechanism on the harvesting effect, thereby being rich in functions and further being capable of realizing 'one machine multi-purposes'.

Description

technical field [0001] The invention relates to the field of agricultural machinery, in particular to a multifunctional test stand for testing a reel-chain type sunflower header. Background technique [0002] Sunflower is an important economic crop and main oil crop in our country. The sunflower in the flowering stage has high ornamental value, and the mature sunflower seed is a kind of delicious food, because the sunflower seed is rich in saturated fatty acids that are beneficial to human health. Sunflower oil Known as "healthy edible oil". my country's sunflower planting area ranks sixth in the world, but the planting patterns are diversified, the row spacing is different in different regions, there are various planting varieties, and the plant heights vary greatly. The difficulty of sunflower mechanized production lies in the harvesting stage, while the difficulty of sunflower mechanized harvesting lies in the lack of breakthrough in sunflower harvesting platform technol...

Problems solved by technology

There are many types of foreign cutting units, but most of them have huge cutting widths and have high requirements for plots and planting modes. The foreign land is large and flat, and the planting mode is single, which is different from the small and scattered fields in my country, with various planting modes and agronomic parameters. The adaptability to national conditions is poor, and the price is expensive. The research and development of sunflower harvesting machinery in my country started relatively late. Therefore, it is very important to speed up the development of multi-purpose, small and medium-sized, low-loss, low-cost reeling chain sunflower harvesting units that meet my country's national conditions.

[0004] Now there is a special reel chain sunflower header (patent number: CN201510833104.1), but there is no test equipment for the reel chain sunflower header, and it is impossible to test the row operation of the reel chain sunflower header. Feasibility in working environments such as row operations, unable to obtain performance parameters such as power consumption, torque, and header seed loss
