Abstract

Usage: in vertically spindle cotton harvesters. SUMMARY OF THE INVENTION: In the lower support of the spindle, an elastic element is installed between the sliding bearing and the surface of the cavity of the spindle g, the length of which is 0.6-0.8 bearing length. This embodiment eliminates seizure of the bearing during misalignment. 6 ill.

Description

The invention relates to agricultural machinery, in particular to nodes of a vertically spindle drum of a cotton picker.

The purpose of the invention is to increase operational reliability.

Figure 1 shows a diagram of the lower support of the spindle in the process of collecting raw cotton; figure 2 - diagram of the deformation of the elastic element when exposed to the spindle of an external load; in Fig.Z - diffuse shape of the sleeve; Fig. 4 is a diagram showing the movement of the lower end of the spindle in the transverse direction; figure 5 - barrel-shaped metal-ceramic sleeve; Fig. b shows the lower support of the spindle.

The lower support consists of a lower disk 1, in which the fingers 2 are fixed. A metal-ceramic sleeve 3 is mated with a finger 2 over a sliding fit. To prevent the movement of metals; frame sleeve down along the finger, the latter has a stepped shape. Between the outer surface of the ceramic-metal sleeve 3 h cavity spindle 4 mounted elastic element 5,

To exclude the movement of the elastic element along the axis of the finger in Fig. B, an embodiment is also presented in which an additional safety pin 6 is provided.

Installing an elastic element between the spindle cavity and the cermet sleeve will allow:

ensure uniform and free rotation of the spindles in case of misalignment of the lower and upper disks, as well as with significant spindle deflections reaching 15–20 mm;

ensure the durability of the drive belts, as well as the entire spindle rotation drive mechanism;

to exclude the possibility of breakage of the metal-ceramic sleeve when the finger is distorted;

damp the dynamic loads acting on the finger-sleeve pair and the entire cotton picker;

significantly reduce the noise level during operation of the cotton picker;
