Description

This invention relates to agricultural machinery construction, in particular to machines for the calibration of fruits and vegetables.

The purpose of the invention is to increase the productivity and quality of calibration due to the orientation of elongated fruits along rolls,

Figure 1 shows a front view of a fruit and vegetable calibration machine; figure 2 - gauge canvas, top view.

The machine for calibrating fruits and vegetables contains frame 1, loading device 2, unloading conveyors 3-5 and a calibration sheet formed by transverse rollers 6 and 7, Rollers 6 fixedly mounted on chain 8, conveyor alternated with movable rollers 7, which are mounted on top 9 and lower 10 guides and in vertical slots of brackets 11 attached to chain 8.

Guides 9 and 10 have additionally wavy-shaped copying surfaces in horizontal section. The brackets 11 have an abutment 12, with which they rest on a stationary roller 6. At the ends of the movable rollers 7, a ball 13 is rolled to interact with a wavy carbon copy with the surface of the guides 9 and Y. The ramp 14 is installed between the branches of the calibration cloth and cloths - gates 15.

The transverse rolls 6 and 7 form between themselves predetermined calibrating gaps, the size of which depends on the position of the movable rolls 7, determined by the setting of the direction of 9.9 and 10. The installation of the movable 1 | 1X rolls 7 allows them to move in the vertical grooves of the crown 58502 2

Theories from copy guides in both the vertical and horizontal directions.

Machine for calibrating fruits and

5 vegetables works as follows.

The fruit from the loading device 2 enters the transverse rolls 6 and 7 of the upper branch of the calibration cloth, where, depending on

 The size is divided into fractions, one of which (coarse) is carried away by the upper branch of the gauge cloth to the unloading conveyor of a large fraction, and the other, having a size smaller

 5 of the established calibration gap, falls through and on the sloping sheet 14 is fed to the rolls 6 and 7 of the lower branch of the calibration web. Moving rolls 7 lower branches

The 20 gauge sheet, interacting with the lower guide 10, is formed with the fixed rollers 6, the gaps are smaller than on the upper branch of the blade, due to which the remaining

25 root crops are divided into small and medium fractions. The movable rolls 7 of the lower leg of the calibration web, the exit from the interaction with the lower guide 10, are lowered below

30 by its own weight in the vertical slots of the brackets 11 and open enough clearance for the middle fraction of the fruit to come down from the lower branch of the gauge sheet to the remote vehicle.

35 porter 3 middle fraction. Fruits of the fines fraction are propelled through the calibration gaps of the lower branch of the gauge cloth onto the remote conveyor 4 fines.

40 Horizontal oscillations of the moving rolls and gates improve the orientation of elongated fruits in parallel to the calibration clearances, which contributes to a qualitative calibration of the fruits.
