Brush roll type picking table

Abstract

The invention relates to a brush roll type picking table and belongs to the technical field of agricultural machinery. The picking table comprises at least one pair of dividers with cone heads, which are arranged at the front end of a picking table frame; picking heads are arranged behind the dividers; each picking head comprises a pair of left and right brush rolls which are provided with low front parts and high rear parts, are supported on the picking table frame and rotate towards the opposite directions at the same speed; a group of brush plates radially extending are peripherally distributed on each of the left and right brush rolls; longitudinal helical conveyors with V-shaped connecting grooves are respectively arranged below the outsides of the left and right brush rolls; a pair of left and right anti-pulling rollers which are basically horizontally supported and rotate towards the opposite directions at the same speed is arranged at the lower part inside each pair of left and right brush rolls; and anti-pulling teeth radially extending are distributed on the peripheries of the left and right anti-pulling rollers. The brush roll type picking table not only solves the problems of low harvesting rate and high loss ratio of a spindle-type cotton picker, but also solves the problem of easiness for pulling a cotton stalk of a compound rod type cotton picker.

Description

technical field [0001] The invention relates to a picking platform, in particular to a brush-roll type picking platform, which belongs to the technical field of agricultural machinery. Background technique [0002] my country's cotton planting areas are widely distributed, and can be roughly divided into the Yangtze River Basin, the Yellow River Basin, and the inland cotton areas of Xinjiang. The geographical conditions and climate characteristics of these areas are different, which brings difficulties to mechanized cotton production, especially mechanized harvesting. . The climate in Xinjiang is dry and there is little rain. The moisture in the cotton growth process is provided by drip irrigation. Therefore, it is relatively easy to control the growth of cotton, and the mechanization of the cotton production process is relatively easy to realize. However, at present, cotton harvesting by machine is only partially realized in Xinjiang cotton region, and other cotton regions ...

AI Technical Summary

Problems solved by technology

[0004] However, due to the unique geographical environment in the Yangtze River cotton area, there is more rain, the air and soil humidity are high, the cotton opening period is relatively long, the opening rate is relatively low and the opening is not smooth

There are many stiff flowers and semi-twisted flocs, which are not easy to be entangled and easy to fall. The use of spindle-type cotton pickers generally has the problems of low harvesting rate and high loss rate, and picking is very difficult.

On the other hand, most of the Yangtze River cotton area adopts ridge planting, and drainage ditches are usually opened for drainage. Due to the high soil humidity, cotton is easy to pull up, which has become a difficult problem for picking with double-finger cotton pickers.

In addition, due to structural limitations, the existing picking machines cannot meet the needs of picking more than two rows at the same time
