Description

The invention relates to agricultural machinery, in particular to machines for harvesting vegetables, mainly tomatoes and sweet peppers.

The purpose of the invention is to improve the quality of fruit production and the fullness of fruit harvesting.

FIG. 1 shows a side view of the machine: FIG. 2 shows section A-A in FIG. one.

The vegetable harvesting machine comprises mounted on frame 1 right 2 and left 3 guide rails with bus guides 4 and 5, right 6 and left 7 collecting conveyors, feeding conveyor

8 with combs 9, receiving 10 and loading 11 fruit transporters.

The frame 1 is made all-welded from two sidewalls installed in the working position at an angle of 15-20 ° to the horizon, and can be rotated relative to the axis of the drive shaft of the receiving conveyor 10 to move the machine from the working position to the transport position and back.

The guide combs 2 and 3 are rigidly fixed in the lower part of the sidewalls of the frame 1 in such a way that in the middle part between them there remains a clearance through the trunk of plants. By land m na | yu yu

The guide combs have bush shrouds 4 and 5 that serve to guide the lateral stems to the guide combs.

Collecting conveyors 6 and 7 are made in the form of endless chain loops 12, located on the leading 13 and driven 14 asterisks.

On the links of the chains by means of hinges 15, combing fingers 16 are mounted.

A guide track 17 is rigidly fixed above each collecting conveyor on the frame, which serves for fixing the combing fingers 16 in predetermined positions.

The stripper pin 16 is made of spring wire with a diameter of 6-8 mm in the form of a two-arm lever, the upper end of which enters the guide path 17.

Each combing finger 16 contains a spring 18 mounted between the hinge 15 and the upper end of the lever.

The collecting conveyors 6 and 7 are mounted in the frame behind the guide dies so that the combing fingers below pass under the guide dies 2 and 3.

The feeding conveyor 8 is made on two sleeve-roller chains x19, on the links of which the fingertips 9 are rigidly fixed perpendicular to the axis of the chain contours of the conveyor. It is mounted above the guide dies 2 and 3 and collecting conveyors 6 and 7 and is intended to lift the fruits along guide pins 2 and 3 and supporting them on collecting conveyors 6 and 7.

The receiving conveyor 10 is fixed on the frame 1 and is located under the collecting conveyors 6 and 7 in the bend zone of the combing fingers 16 down.

To load the fruits into the vehicle, at the end of the receiving conveyor 10 is mounted on the frame across the direction of movement of the machine the loading conveyor 11.

When the machine is moving, the fingers of the guide combs 2 and 3, inserted under the bush, raise the lateral stems of plants and fallen fruits from the ground. At the same time, bush shafts 4 and 5 assist in raising the lateral stems of the plants to guide combs 2 and 3.

The fingers of the combs 9 of the feeding conveyor 8, moving in the direction opposite to the direction of movement of the machine, with an equal speed to it, feed the plants and fruits raised by guiding requirements 2 and 3 onto the collecting conveyors 6 and 7.

When the internal branches of the collecting conveyors 6 and 7 move against the direction of movement of the machine at an equal speed, the stalks of the plants are evenly distributed in the gaps between the combing fingers 16. Due to the inclined arrangement of the collecting conveyors, the combing fingers 16 separate the fruits from the stalks of the machine.

Fruits separated from the bushes, supported by combs 9 of the feeding conveyor 8, are transported upwardly by collecting conveyors 6 and 7. Due to the presence of the guide tracks 17, the stripping fingers at a given height are squeezed down and the fruit is dropped onto the receiving conveyor 10.

From the receiving conveyor 10, the fruits arrive at the loading conveyor 11, which loads them into a vehicle. Green mass passes under the conveyors and remains in the harvested field.

Thus, obliquely mounted collecting conveyors with combing fingers perpendicular to the axis of the chain contours ensure free passage of the plant stems in the gaps between the fingers, which eliminates the tearing of the stems and significantly affects the quality of fruit production. In addition, the guide comb in combination with the feeding conveyor ensures the selection of fruits from the ground. The use of the invention allows for increased harvesting by more fully grasping the fruit and improving the quality of fruit production. The machine can be used for continuous and for selective harvesting of fruits, as well as selection of fruits from the ground.
