SU380272A1 - BOTTOM SUPPORT OF THE VERTICAL SPINDLE OF THE FLAP-MACHINE MACHINE - Google Patents

Description

BACKGROUND OF THE INVENTION The invention relates to drum harvesting machines.

There are known spindle drums with a lower onor, consisting of a spreader, fastened in the lower disc of a nlideal drum, on which the spindle, covered by the bottom of the collar, is supported, and its cup. In the bottom of the bowl there is a window, sovnadayush, it with a window in the disk. It serves to remove the whining and oil that has been poured into the cup. From the bottom of the window, the discs are closed with a protective ring against hinging earth clumps.

The disadvantage of this design of the lower support of the pulley drum is that it is almost impossible to clean the cup of the mixture of dust and oil. Therefore, this design has not found practical application.

The purpose of the invention is to create a lower support for a vertical spindle of a cotton harvesting machine, simple but designed to clean the protective cup and prevent jamming of the spindle.

This goal is achieved by the fact that the spindle is provided at the end with protrusions that destroy the clots of dirt formed during the operation of the apparatus and throw them out of the protective cup.

FIG. 1 shows schematically the described spindle support in a longitudinal section; pas figs. 2 is the same, the section along .4-.4 in FIG. one.

The spindle / has projections 2 on the end. It rests on pin 3 fixed in the lower disk 4 of the spindle drum. The lower end of the spine; the unit covers a protective cup 5 with a window 6 in the side wall located above the level of the upper plane of the lower disk of the spindle drum.

During operation of the cotton harvester, the fly hits the protective lash through the gap between its inner wall and the outer surface of the spindle. It is mixed with oil flowing from the spindle head and settles to the bottom of the cup. The protrusions 2 at the spindle face capture lumps of dirt and throw them out of the protective cup through the window 6 onto the upper plane of the lower disk 4 of the spindle drum, from where they are dropped to the ground under the action of centrifugal forces.

Subject invention

The bottom of the vertical clamp of the cotton picker, containing a finger entering the spindle body, fixed in the lower disk of the spindle drum, protects the cup with ca. 1) for ejecting litter.
