(54) MACHINE FOR CLEANING FRUITS

one

The invention relates to the field of agricultural engineering and can be used for selective and continuous harvesting of vegetables, in particular tomatoes.

Known machine for cleaning; fruit, including a finger comb and a feed drum mounted above it with a horizontal axis of rotation, perpendicular to the direction of movement of the machine, having transverse gripping elements,

The known machine is characterized by the impossibility of selective harvesting of fruits and the inactivity of the comb. This results in increased damage to the fruit as a result of excessive deformation during combing and frequent clogging of the comb by plant mass, which leads to disruption of the harvesting process.

The purpose of the invention is to reduce fruit |

This goal is achieved by the fact that the fascinating elements of the polypropylene are in the form of forcibly rotating horizontally mounted vals and grooves arranged parallel to the grooves. For combing and selectively harvesting vegetables, the apparatus is equipped with a watering comb, which is priced fluctuating with the adjustable Step of spreading fingers. Forwarding of individual fruits from the internal Cavity is carried out using the Chimney Board, which has access to 5 unloading conveyors.

Fig, I shows the proposed cleaning machine, a general view; 2 - the same, side view.

The machine consists of a rotating drum I, assembled with planetary rollers 2, Drum I is supported by the machine, and rollers 2 are installed in the sidewalls. drum bearing supports, 5 | Inside the sides of the drum sides

are connected by parallel rollers with grooves 3, each of which corresponds to a planetary roller.

Chutes 3 are positioned so that, with possible rotation of the roller in the direction shown on the latter, the fruit is thrown into the chute for further transportation to the ramp 4. The Chute is located inside the drum and is intended to evacuate the collected fruit to the discharge conveyors 5 A comb b is installed under the drum. It is suspended from the frame and dialed from the fingers with adjustable jnaroM their arrangement. The purpose of the combing efficiency and the implementation of selective harvesting of vegetables is the woody comb made of oscillating,

The machine works as follows.

Comb b, located under the drum I, making an oscillatory motion in the horizontal plane, combing the plants, and drum I, rotating, captures the plant stems with fruits. Thus, the fruits are concentrated in the zone of contact with the planetary rollers 2, where they are subjected to

difficult-deforming effect from the roller and the comb. This effect is expressed in the simultaneous bending and torsion of the stem, followed by separation and throwing of fruit into the bearing chutes. 3. The gill carries the fruit to the upper part of the drumTi I. their removal to the unloading conveyor 5.

SUBJECT OF INVENTION

A machine for harvesting fruits, such as tomatoes, including a finger comb and a feed drum mounted above it with a horizontal axis of rotation, perpendicular to the movement of the machine, having transverse

(Elements, characterized in that, in order to reduce damage to plots, the transverse gripping | elements are made in the form of forced-rotating horizontally mounted rollers and arranged parallel to the rollers of the grooves
