Self-propelled complex-finger type cotton picker

Abstract

The invention relates to a self-propelled complex-finger type cotton picker, belonging to the technical field of agricultural machinery. The self-propelled complex-finger type cotton picker comprises a cotton boll picking platform, a wind power conveying device, a cotton boll separating device, an impurity removing device and a cotton boll collecting box; the cotton boll picking platform is provided with a cotton boll picking finger rod row and a seed cotton delivery outlet; the delivery inlet of the wind power conveying device is in butt joint with the seed cotton delivery outlet of the cotton boll picking platform and is connected with the inlet of the cotton boll separating device; the outlet of the cotton boll separating device is connected with the cotton boll collecting box through the impurity removing device; the cotton boll separating device comprises a separating box; a spike roller is arranged above the bottom of a hopper of the separating box; a direct-current channel is formed above the spike roller; the joint of the inlet of the cotton boll separating device and the hopper is provided with a cotton pressing brush; a grille plate which extends to the outlet of the cotton boll separating device is arranged below the spike roller; and the bottom of the hopper is provided with the cotton boll collecting box through a wind closing device. The self-propelled complex-finger type cotton picker effectively overcomes the defects of non-thorough cotton boll separating and easy blocking, prevents the cotton boll from entering the impurity removing device to cause cotton dying and damping, reduces the impurity rate of the picked cotton and is beneficial to improving the grade of the cotton.

Description

technical field [0001] The invention relates to an agricultural product harvesting machine, in particular to a self-propelled multi-finger cotton picker, which belongs to the technical field of agricultural machinery. Background technique [0002] Cotton is an important material related to the national economy and the people's livelihood, and plays an important role in the development of the national economy. Harvesting is the most labor-intensive and most labor-intensive key link in cotton production, and manual picking is still used in many areas. At present, there are mainly two types of machinery that are actually used in cotton harvesting: one is the spindle picking type (also divided into horizontal picking spindles and vertical picking spindles); the other is the comb tooth type. Among them, the spindle picking cotton picker has complex structure, high price, high mechanical energy consumption (above 200KW), and low picking income, which is not suitable for my countr...
