The invention relates to agricultural machinery, in particular to machines for picking fruits from the soil surface.

The fruit picker is known, containing the frame and mounted on it, mounted at an angle to each other, and its pick-up and transport devices located behind them, made in the form of two meetings of rotating screws inclined and parallel to each other, under which the tray is mounted u in a plane parallel to the axis of the screws.

The known picker does not provide sufficient completeness of the selection of fruits due to poor copying of the soil by the augers, and the working bodies cause significant mechanical damage to the fruits. The fruits picked up by the augers are heavily littered with earth and plant residues 1.

A fruit picker is also known, containing a frame with pulleys mounted on it, covered by an endless gripping circuit 2.

However, such a pick-up does not ensure the capture of fruits having a hard surface.

The aim of the invention is to improve the capture of the fruit.

This goal is achieved by the fact that the gripping contour is made in the form of an elastic-elastic sleeve with a longitudinal slit along the entire length, and the pulley axes are spaced from each other at a distance equal to at least four times the circumference of the sleeve described around the cross section. the diameter of the said pulleys does not exceed one of its length.

FIG. 1 shows a fruit picker, side view; in fig. 2 - view A of FIG. one; in fig. 3 - view B of FIG. 2 with a 1/4 cut of the pick-up member.

The fruit picker consists of a frame 1, to which a frame 4 is hinged by means of the front 2 and rear 3 shafts, fitted at the ends with forks 5, covering the driving 6 and driven 7 pulleys. The even leading pulleys are rigidly fixed on the rear shaft 3, and the odd ones on the front shaft 2. The shafts 2 and 3 are connected to the gearbox 8, on which the hydraulic motor 9 is installed by means of the chain 10. The driven pulleys 7 are freely installed in the forks 5 by means of the axles 11. Each pair of leading b and driven 7 pulleys is enveloped in a fascinating contour 12, made of an elastic-elastic runawa with a longitudinal slit along the entire length, and the axles of the shchivs are spaced at a distance equal to at least four times the circumscribed circumference of the cross section , Wherein the diameter of said pulleys is less than a length thereof. On the pulleys b and 7, the exciting contours 12 are turned into bands L, and between them the edges M of the ribbon L are gradually reduced to the original shape of the sleeve, aided by the elastic properties of the material, for example rubber. Behind the driven pulleys 7, there are located support copying rollers 13. Brackets 14 are rigidly attached to frames 4 with guide rollers 15 above the lower branch of catching circuits 12, which hold it in a horizontal position. Under the lower branch of the even gripping contours 12 there is a transverse conveyor 16, and under the lower branch of the odd gripping contours 12 are pitched boards 17 covered with an elastic material. The transverse conveyor 16 has a flexible connection with the gearbox 8 through the chain 18. At the place of attachment of the brackets 14 to the frames there are springs 19 fixed, on the free ends of which are installed the rollers 20, which are pressed by the springs to the sides of the lower branch of the exciting contours 12 at the point of their transition from a horizontal position to sloping. The pickup works as follows. During the forward movement of the pick-up unit with the tractor on the site where the fruits, exciting contours 12 lie on the ground, receiving movement from the hydraulic motor 9 through the gearbox 8, chain 10, shafts 2 and 3 and pulleys 6 run their upper branch in the direction of the unit movement, and bottom - in the opposite direction with a speed exceeding the translational speed by 1.5-8 times, depending on the density of the lying fruits. The raid on shchivy 6 and 7, they unfold into a ribbon, and the runaways from them gradually fold to take the form of a sleeve, with the image of the shed T, limited by the edges of M, the axis line on the driven pulley 7 and the descent of the edges of M. In the area of the throat T, in the course of folding, the fruits are scooped up from two sides to the longitudinal line of the axis of the exciting contours 12, scattering them due to the excess speed of the exciting contour over the translational speed of the unit. The rollers 20 prevent the exciting contour from opening up, and the springs 19 create the necessary force through the rollers 20 to the exciting contour 12. This prevents small fruits from rolling out of the exciting contour. The captured fruits are transported inside the gripping paths 12 upwards without rolling. The fruit is unloaded onto the transverse conveyor 16. Due to the fact that the lower branches of the gripping circuits 12 run onto the drive pulleys 6, unfold on them into ribbons, the fruits are released in the pharyngeal area of P. The collected fruit transmits the transverse conveyor 16 to the place of packing. The use of a pick-up can dramatically reduce labor costs. Claims of the invention A fruit picker comprising a frame with pulleys mounted on it, covered by an endless exciting contour, characterized in that, in order to improve the capture of fruits, the exciting contour is made in the form of an elastic-elastic sleeve with a longitudinal slit along the entire length, and the axes of the pulleys are each from a friend, at a distance equal to at least four times the circumference of the circumference described around the cross-section of the sleeve, and the diameter of said pulleys does not exceed one of its length.
