SU1489631A1 - Vertical-spindle drum of cotton picker - Google Patents

Description

The invention relates to agricultural machinery and can be used in spindle

cotton harvesting drums. The purpose of the invention is to increase the efficiency of cotton harvesting. Vertical spindle drum contains a vertical shaft 1, upper 2 and lower 3 discs, spindles 4, removable elements 5 and means for driving them, including a stationary disk 6 with a cam groove 7 and drove 8. For supplying a moistening liquid to the spindles 4 removable elements 5 have on its inner surface, a number of grooves 9, communicating with channels 10-13, through which a moisturizing fluid is supplied, with channel 13, made in carrier 8, acting as an interrupter, depending on the change in the radius of curvature of the cam groove 7.

The invention relates to agricultural machinery and can be used in the spindle drums of the cotton harvester. d

The purpose of the invention is to increase the efficiency, efficiency of cotton harvesting.

Fig "1 shows a vertical spindle drum, a general view; in fig. 2 - the position of the carrier channel, ω corresponding to the constant radius of curvature of the cam groove; Fig. 3 is the same, when changing the radius of curvature of the cam groove profile; 4, the position of the cleaning zone in the technological cycle.

Vertical spindle drum. contains a vertical shaft 1, upper 2 and lower 3 disks, spindles 4, removable elements 5 made of elas-20 of a material, and means for driving them, including a fixed disk 6c with a cam groove 7 and driven 8,

Removable elements 5 have a vertical row of horizontal grooves 9, 25

located on their inner surface, and a longitudinal channel 10, which communicates with grooves 9.

The vertical shaft 1 is made with a longitudinal channel 11 communicating 30 with the radial channels 12 of the upper disk 2. The radial channels 12 through the channels 13, made in the carriers 8, are connected to the corresponding longitudinal channels 9 of the removable elements 35.

When the shaft 1 of the drum rotates, together with the upper 2 and lower 3 discs, they move with the carrier 8 removable elements 5, the position of which relative to the spindle 4 determines the profile of the cam groove 7,

Profile change, t, e "change in the radius of curvature of the cam groove 7,

leads to the contact of the removable element 5 with the spindle and simultaneously provides fluid communication in the channels 13 and 12, as a result of which the liquid flows through the longitudinal channel 10 to the grooves 9, moving along them due to centrifugal forces.

The constant radius of curvature of the profile of the cam groove 7 leads to the removal of the removable element 5 from the spindle 4 and the interruption of fluid communication in the channels 13 and 12.

Claims (1)

Claim Vertically spindle drum of a cotton harvesting machine, containing vertical wad, upper and lower spindle disks, removable elements made of elastic material in the form of slats, and Means for their drive, having a fixed disk with a cam groove and drove, characterized in that cotton harvesting efficiency, removable elements have a vertical row of horizontal grooves located on their inner surface, and a longitudinal channel connecting with the grooves, the vertical drum shaft is made with a longitudinal channel The upper disk is made with radial channels extending from the channel of the vertical shaft and directed to the carrier, the carrier is made with channels connecting the radial channels of the upper disk with the corresponding longitudinal channels of cleaning elements, and the channels in the carrier communicate with the corresponding radial channels. channels of the upper disk in the zone of variation of the radius of curvature of the cam groove profile. 1489631
