Description

aggregated with a tractor, equipped with a compressor, having a receiver connected with a hose and a hollow rod 6 with a fruit catcher 7 in the form of a spring-loaded spring 10 cup 8. A pneumatic palm 11 with elastic fingers is attached to the bottom of the cup 8. Floor of the neck 12 of the cup 8 is planted on the bearing 13, which is located in the housing of the head 14 of the rod 6, i.e. trap 7 has freedom of rotation. At the end of the neck 12, a wing 15 with spherical vanes is attached along its outer diameter to serve to rotate the catcher under the influence of compressed air. The end 16 of the hollow rod 6, which enters the head 14, has two tips 17 and 18, distributing compressed air with hoses 19 and 20 to the pneumatic palm 11 of the cup 8 and wing 15. Compressed air enters through the hose 19 into the pneumatic palm 11 with fingers 9 through the neck 12 of the cup 8 of the catcher 7. To allow and stop the flow of compressed air into the pneumatic palm 11 with fingers 9 and the wing 15, their hoses 19 and 20 are equipped with spring levers 21 and 22. The hose of the pneumatic palm 11 with fingers 9 has a reset button 23 for pressure relief in them pressure containing th rod to the valve. To remove compressed air from the head 14, it has an outlet 24. 24 sludge.

The invention relates to agricultural machinery, in particular to devices for picking peach fruits and valuable varieties of pears and a block. The aim of the invention is to reduce fruit damage and simplify designs. ;;

Figure 1 shows a preferred device; figure 2 - catcher with a rod head.

The device comprises a trailer 1 (Fig. 1) for transporting fruits, aggregated with a tractor 2, equipped with a compressor 3, having a receiver 4, connected by a hose 5 and a hollow rod b with a catcher 7 in the form of a glass 8 with elastic fingers 9. A catcher 7 of fruits is made in the form of a spring 8 of a cup 8 (FIG. 2), to the bottom of which a pneumatic palm 11 with fingers 9 is attached. The floor of the neck 12 of the cup 8 is mounted on a bearing 13, which is located in the head housing of the rod 14 6, i.e. trap. 7 has the ability to rotate. At the end of the neck 12, a wing 15 with spherical blades is attached along its outer diameter, which serves to rotate the trap under the influence of compressed air. The end 16 of the hollow rod 6, which enters the head 14, has two tips 17 and 18 distributing compressed air with hoses 19 and 20 to the pneumatic palm 1T of the cup 8 of the catcher 7 and wing 15. Compressed air enters through the hose 19. into the pneumatic palm 11c fingers 9 through the neck 12 of the cup 8 of the catcher 7. To allow and stop the flow of compressed air into the pneumatic palm 11 with fingers 9 and wing 15, the hoses 19 and 20 are equipped with spring levers 21 and 22. The hose of the pneumatic palm 11 with fingers 9 has a reset button 23 for pressure relief pressure, s holding the rod to the valve.

To remove compressed air from the head 14, it has an outlet 24.

The catcher 7 is designed to capture and rotate (rotate) the fetus around

its stalks. Its rod 6 can be made of hollow plastic or kapron. The pneumatic palm 11 with fingers 9 can be made of thin elastic rubber, like a medical glove attached to the bottom of glass 8.

The operation of the device is as follows. The machine operator stops the tractor 2 near the tree, turns on its PTO,

the compressor 3 generates compressed air and directs it to the receiver 4 for accumulation, and from there it enters through the pressure reducing valve 6 through a hose 6 to the fruit pick-up device, which the machine directs to the fetus. The fetus enters trap 7, i.e. into the pneumatic palm 11 with fingers 9. Compressed air from the receiver 4 enters through a hose 5, which passes into the hollow rod 6, where for better control of compressed air it is divided into two flows: through the hose 19, air enters the hollow volume of the palm 11 and fingers 9 only after pressing lever 21 for a few seconds, whereby the volume of fingers A increases

to volume B, and thus the volume of space C in which the fetus is located is softly wrapped, i.e. squeezing the fetus. Then the machine operator presses the lever 22, directing the flow of compressed air to the spherical blades 15, mounted on the neck of the glass 8, which absorb the force of the flow of compressed air. Due to this, the pneumatic palm 11 together with the glass 8 rotates, whereby the fetus with the stalk is torn off, and the exhaust air leaving the vanes 15 leaves through the openings 24 in the head to the outside. By releasing the lever 21, the air supply to the blades 15 is stopped, and under the action of the spring, the pneumatic arm rotates. rotating to its original position. Then, the machine operator delivers the catcher 7 to the place of laying the fruit, pressing the button 23, the airspace of the fingers B and the palm of the hand 11 communicates with the atmosphere, thanks to the Invention A device for collecting fruits, mainly peaches, containing an exciting working element mounted on a hollow rod in the form cups with a housing located in it having elastic fingers, a source of compressed air and a pneumatic drive. different in that. what with

whereby the fingers occupy the initial position A; thereby releasing the fetus from the compressive action of the six pneumatic fingers of the pneumatic hand. Next, the operation of supplying the pneumatic arm to the fetus is repeated.

This flow chart completely simulates the principle of picking fruit by hand.

Thus, the removal of one fruit is carried out in a few seconds, and the productivity of collecting delicate peach fruits and valuable varieties of pears and the block using the device increases several times in comparison with manual harvesting. The work is carried out with high quality picking, and the fruits are not damaged.

In order to simplify the design and reduce damage to the fruit ™, the body of the working body is made in one piece with elastic fingers in the form of an elastic pneumatic chamber rigidly fixed in the glass, and the glass is mounted on the rod with the possibility of rotation from the air drive.
