Cotton picking robot

Abstract

The invention relates to a cotton picking robot, and belongs to the technical field of agricultural machinery. According to the robot, the whole unmanned picking process of cotton is achieved, and the functions comprise automatic moving and machine vision guiding cotton picking. The robot comprises an automatic mobile platform, a vision cotton picking head and a cotton collection bin. The automatic mobile platform conducts path planning and real-time guiding according to GPS information, real-time path and posture adjustment is conducted according to vision and an automatic row-controlled sensor, mobile platform posture and speed tracking is conducted according to an angular acceleration sensor and acceleration sensor information, when picking tasks are completed or a failure occurs or the electric quantity and cotton picking weight reach a limiting value, returning is conducted. The vision cotton picking head conducts visual identification on the cotton mature degree and the spacial position through a machine, and a cotton picking spindle unscrews the cotton off in a rotating stretching mode and then retracts into a picking box, and the cotton is scraped off through a cotton brushing pad. The picked cotton is conveyed to the cotton collection bin installed on the automatic mobile platform through wind power.

Description

technical field [0001] The invention relates to a cotton picking robot, in particular to a cotton picking device based on visual information, and belongs to the technical field of agricultural machinery. Background technique [0002] China's cotton planting accounts for 30% of the world's planting area, and cotton picking has important economic value. The cotton harvesting period is generally from September to October, about 60 days. The picking requirements are: the cotton in the same cotton field has a sequence of maturity, and is usually picked every 5 to 7 days; , sold in grades; reduce the mixing of impurities and improve the quality of seed cotton. [0003] There are two ways of picking cotton: manual picking and machine picking. The advantages of manual cotton picking are high yield and low impurity content. There are no special requirements for cotton planting. Even if the shape of the cotton field is irregular or uneven, it can be picked. It is not necessary to sp...

Problems solved by technology

[0006] The primary purpose of the present invention is: to overcome the deficiencies of current artificial cotton picking and machine picking, both can achieve the high picking rate and low impurity rate of manual picking, and can reach the high efficiency of machine picking, but there is no machine picking. The limitations of cotton, such as strict requirements on the planting distance of cotton plants, defoliation of cotton before picking cotton, etc.
