The invention relates to agricultural machinery, in particular to aggregates for picking tomatoes and other vegetable crops, such as radishes and onions.

The purpose of the invention is to increase the efficiency of the fruit picking process.

The drawing shows a diagram of the unit. The assembly for picking tomato fruits contains a frame 1 with running wheels 2 and 3, on which a device for cutting stems of plants in the form of a U-shaped bracket 4, a pair of shoes 5 and 6, coil springs 7 and 8, a separating conveyor 9, a tray is mounted 10 and the impeller 11 with uprights 12 and brushes 13, a device for separating fruits in the form of shaking drums 14, an external conveyor 15, a rotary chopper 16 and a fan (17.:.; ... .. - .... .:: ..

A device for cutting plant stems is mounted cantilever in front of frame 1. Shoes 5 and 6 and coil springs 7 and 8 serve to cut the stems at a predetermined depth. A tray 10 is installed in front of the separating conveyor 9, and an impeller 11 is located above it, each spring-loaded strut 12 of which is telescopic. The blades are made in the form of brushes 13 and attached to the ends of the telescopic racks 12.

The tray 10 in the front part is made in the form of a horizontal surface, the middle part has a curved shape with a radius increasing towards the separating conveyor 9, and the rear surface is installed with the overlap of the front part of the separating conveyor 9.

Next is a fruit separation device made in the form of shaking drums 14, an external conveyor 15, behind it there is a rotary chopper 16 and a fan 17.

An assembly for picking tomato fruits works as follows.

To adjust the working bodies 4-8 to a predetermined depth, the unit mounted on the tractor in a floating position, the floor is lowered onto the surface to be treated. During the forward movement of the tractor with the aggregate, the U-shaped scraper 4 under the influence of the coil springs 7 and 8 is deepened to a predetermined depth and, under the mulching soil layer, under-. cuts the stems of plants, do not hurt when: Then the fruits of tomatoes, which lie directly on the surface of the soil. Trimming stems and passing through P-th

bracket 4, the tomato fruits are thus brought to a single physical state lying on the surface, forming a harvesting mass. Then given mass is lobed

with the wheel 11 and brushes 13, the horizontal part of the tray 10 is fed to the soil surface copying, then it is fed to the curved part of the tray 10 and then to the separating conveyor 9. Therefore, when the unit is operating, the impeller 11 with the uprights 12 and brushes 13 does not move in a circle, but by a closed local curve (program), providing direct contact in the lower part

5 brushes 13 with soil, and moving along the curved part of the tray 10, sweeps the harvesting mass lying on the surface and feeds it through the tray 10 to the separating conveyor 9.

0 In such a process, the specific gravity of a homogeneous fraction of the soil in the harvesting mass takes a minimum amount, which, while still moving along the inclined part of the separating conveyor 9

5 is separated. Then, the harvesting material from the separating conveyor 9 enters the fruit separation device, i.e. on shaking drums 14, where the yut is separated. with fruits from plants. After that fruit

0 fall on the external conveyor 16, and the stems in the rotary chopper 15.

The portable conveyor 16 delivers the fruit to the next vehicle next, while the fruits are fed 5 with the external conveyor 16, they are blown by the discharge air stream, which is supplied by the fan 17, blowing them, thereby removing the remaining small fractions of the plant mass. Separated

0 from the fruit, the stems enter the rotary chopper 15, where they are chopped, and then scattered across the field as a biological fertilizer, providing good-. rosh struck in the soil during its subsequent

5 processing.

Thus, when using the preliminary preparation process in the harvesting unit and bringing the harvesting mass to a uniform physical condition,

To the state of plants lying on the surface of the soil, through the use of a U-shaped staple 4, sweeping and feeding the harvested material from the treated floor, a complete separation of 5

soil, resulting in a significant increase in the efficiency of the technological process of collecting tomato fruits.

Thanks to the use of design features, such an aggregate can also be used for harvesting other agricultural crops, such as radishes and onions.
