Problems solved by technology

The use of prior art type front plates where the same size and consistent location of the cavities results in reduced optimum picking performance with this unconventional spindle bar
The prior art scraper had to be located in the middle of the two spindle paths, resulting in an excessive distance between the leading or lagging spindle path and the corresponding lagging and leading surfaces of the cavity

Embodiment Construction

[0016] specific implementation plan

[0017] refer to figure 1 (Prior Art), where a portion of a cotton picker row unit 10 is shown having a rotating picking drum 12 with upright picking bars 16 . A plurality of vertically aligned cotton picker spindles 20 are mounted for rotation about a spindle axis 20a by a conventional spindle drive 22 . As row unit 10 moves in forward direction F, a row of cotton plants enters crop receiving area 24 and is engaged by spindles 20 rotating within picking area 26 . Drum 12 rotates about drum axis 12a in direction R at a speed synchronous with the row unit forward speed so that the rearward speed of spindles 20 is approximately equal to the row unit forward speed and the spindle speed in picking area 26 tends relative to the cotton plant. close to zero. The rotating spindle 20 includes a barbed zone 20b that engages and breaks the bolls and removes cotton from the plant.

Abstract

A scrapping plate includes alternating channels or pockets offset in the fore-and-aft direction relative each other to accommodate the different spindle paths associated with spindle bars having spindles which are non-aligned or offset at an angle relative to each other. The offset pockets provide optimal spacing between the different spindle paths and the plate to ensure maximum contact between the spindle picking ends and the cotton bolls to maximize overall picking efficiency. In one embodiment, the pockets are identical but offset in the spindle travel direction from each other and include leading and trailing ends which are angled or curved for conforming closely to the different spindle paths.

Description

technical field [0001] This invention relates generally to spindle cotton pickers, and more particularly to scrapers for improving the picking efficiency of such cotton pickers. Background technique [0002] Cotton pickers typically have a picker bar with evenly spaced spindles positioned vertically in line. The spindles enter the rows of cotton plants and rotate to remove cotton from the plants. The backward speed of the spindles is synchronized with the forward speed of the harvester to generally provide zero relative speed between the spindles and the cotton plants. To help ensure contact with the adjacent spindle in the middle of the boll, a scraper is placed on the adjacent spindle in the picking area to slow down the middle boll and force it into contact with the next spindle. The type of scraper described in commonly-assigned US Patent No. 6,591,597 contains co-shaped cavities arranged in a single line to fully conform to the line picking bar design. The middle bol...
