Description

The invention relates to agricultural machinery, in particular to machines for harvesting cucumbers.

A known machine for harvesting cucumbers, containing a lifting conveyor and a roller fruit separator, is made in the form of rollers horizontally mounted in the transverse direction [1].

The disadvantage of this machine lies in the fact that with large fluctuations in yield, significant damage to the fruits and their loss due to the seizure of the fruits along with lashes and leaves are observed. 15

The purpose of the invention is the reduction of damage to the fruit.

In the proposed machine, the fruit separator is made of two pairs of upper and 20 two pairs of lower rollers, installed in such a way that their line of tangency lies in a horizontal plane passing through the axis of the upper one. the conveyor shaft, and the lower ones - in such a way that the plane passing through the axis of the lower rollers forms an acute angle with a horizontal plane, the apex of which is directed from the conveyor. 30

FIG. 1 shows schematically a cucumber harvesting machine, a general view, ’in FIG. 2 - scheme of fruit separator.

The machine 'consists of frame 1, / driver 2, fruit separator 3, conveyor-pick-up 4, drum-pick-up 5, undermining bracket 6 and support wheels 7. Fruit separator 3 consists of two pairs of small separating rollers 8 of small diameter and two pairs of pulling Rollers 9 large diameter. In each pair, one of the rollers is spring-loaded. The upper pair of fruit separating rollers is located opposite the upper shaft of the conveyor 4. The line of contact of the upper rollers 8 and 9 is in the horizontal plane passing through the upper shaft of the conveyor. The lower pair of rollers 8 and 9 is located iodine angle to the plane passing through the line of contact of the upper pair of rollers at the axis of the upper shaft of the conveyor 4, read! corresponds to the angle of the fall of plants from the conveyor 4.

The fruit 3 is suspended from the frame 1 on the axes 10 and 11 in such a way that by turning the body around the axis 10 and rearranging the point of attachment of the lever 12, you can Change the angle Λ 7762785

The position of the lower fruit separators, depending on the yield and the amount of leaf mass.

Machine for harvesting cucumbers works as follows.

Following along the rows of the plot, the undercut b is undercutting the plants. The level of movement of the bracket is set by the support wheels 7. The conveyor 4 and the pick-up drum 5 take over the plants and transport them to the separator. The upper pair of rollers 8 captures the leaves and whips, and the rollers 9 stretch them, and the fruits are separated. Uncovered plants and fruits with the remnants of lashes fall on the lower pair of rollers, which are captured and stretched leaves and

* whip and then discarded field. The separated fruits fall into the container or on the transverse discharge conveyor.
