Description

A small sunflower disk harvesting and deseeding collection machine

Technical Field

The invention relates to the technical field of sunflower disk harvesting, in particular to a small sunflower disk harvesting and seed removing and collecting machine.

Background Art

The sunflower planting area in northern my country is very large, and the harvesting time is only about 20 days a year. The harvesting time is tight and the intensity is high. When harvesting sunflowers, the sunflower combine harvester will peel the seeds from the sunflower plate and finally transport the seeds to the synchronous transport vehicle. The sunflower combine harvester has a high degree of mechanization and high harvesting efficiency. It can harvest and remove seeds in one go. It is the preferred harvesting machine for many large growers.

However, the use of sunflower combine harvesters also has great defects: 1. The separation of seeds and pulp is not clean, which will cause a large number of seeds to be discharged, commonly known as falling seeds, which is a great waste; 2. The separation process of seeds and pulp will cause certain wear and tear on the outer skin of the seeds, affecting the appearance, and for sunflowers, it will affect the selling price; 3. During the growth process of sunflowers, there will be a certain number of spoiled seeds, and sunflower discs with spoiled seeds are not acceptable, but the sunflower combine harvester cannot distinguish the good and bad seeds during the harvesting process and harvests all of them, which ultimately results in a certain number of bad seeds mixed in the recycled seeds, affecting the quality of the entire seeds.

Due to the above defects of sunflower combine harvesters, many large growers have to give up combine harvesters and use manual harvesting. Manual harvesting usually requires young and experienced harvesters to cut off the sunflower discs with a very sharp machete and then insert the cut sunflower discs on the sunflower stems, and then other personnel will harvest the sunflower discs one by one.

Sunflower straw has medicinal value. If some of the straw can be collected during harvesting, it will not only improve crop utilization, but also effectively increase farmers' income.
