Description

A Pneumatic Safflower Filament Collection System

technical field

The invention relates to a pneumatic safflower filament collection system, which belongs to the technical field of agricultural machinery.

Background technique

Safflower, also known as grass safflower, belongs to Dicotyledonous Plants and Compositae. Originating in Egypt, it is cultivated in many places such as Europe, America, Australia and China. It has the effects of promoting blood circulation, promoting menstrual flow, dispelling stasis and relieving pain. The oil content of the seeds is higher than that of soybeans, among which the linoleic acid content is higher, which has the effect of lowering blood fat and serum cholesterol, and preventing atherosclerosis. , cosmetics and other industries. With the gradual increase of people's demand for safflower, the safflower market is also expanding day by day, and is developing in the direction of industrialization and industrialization. According to the growth characteristics of safflower, the planting density of safflower is high, the height of the achene of the plant is uneven, and the mosaic leaves and achene have thorns, which increases the difficulty of harvesting. Generally, 2-3 crops of safflower can be harvested from growing to withering, which requires that the achenes cannot be damaged when picking filaments. Therefore, the current safflower harvesting is mainly manual harvesting. It is easy to be punctured by flower thorns, and prone to allergic reactions. Harvesting safflower is time-consuming, labor-intensive, and extremely inefficient. During the busy farming season, the harvesting period of safflower coincides with that of cotton, tomato and other crops, which makes it difficult to hire workers. Most of the mature safflower filaments are lost due to failure to collect them in time, which seriously affects the economic income of farmers who grow safflower and restricts the production of safflower. The development of flower industry. The research on safflower harvesting machinery at home and abroad is mostly in the experimental research stage, and no mature harvesting machinery has yet been applied to the market. To realize the mechanized harvesting of safflower silk, it is also urgent to solve the problem of transportation and collection of safflower silk.
