Abstract

FIELD: agriculture.

SUBSTANCE: fruit-picker consists of the housing with connected lower ring with collector, and upper ring moving along axis. The upper ring is fixed to the housing by two V-shaped levers with an axis shifted up by a spring with can be driven by a cable with the rings attached to it. The rings are threaded on a boom. Lower edge of the upper ring stiffly crosses the upper edge of the fixed ring, thus forming scissors for pedicel cut.

EFFECT: operational convenience, decrease of fruit damage.

Description

The technical field to which the invention relates.

The invention relates to agricultural machinery used in horticulture.

State of the art

It is known that for the collection of fruits used stairs and all kinds of fruit raisers.

V. Krutov / 631. 1G63 UDC 634. 1: 635. 1. V. B. Goldman. "A device for the care of the garden." M. Rosselkhozizdat, 1982, 96 pp., Ill. / Planted a mini-basket, assembled from pine planks, 25 cm high, on a pole, they abut against a plywood round 10 cm in diameter, covered with paralon. At a distance of 19.5 cm from the bottom, a hoop covers them, which serves as a knife for trimming the stalk.

The disadvantage of this design is that to trim the stalk, the fruit puller needs to be moved only upward. Successful circumcision occurs only when the fruit is on a thick branch.

To collect large fruits in Hungary / ibid. / Created a mechanical cutter. A blade with a V-neck made of a steel plate 20 × 80 mm in size is nailed to one end of a two-meter pole at an angle of 135 °. Its inner edges are sharpened so that an angle of 25 ° is formed between them. A ring with a diameter of 12 cm is attached under the knife with a cloth bag sewn to it for cut fruits.

The disadvantage of this design is that the insertion of the fetus into the fork is difficult, especially at high altitude.

The most attractive is the fruit picker made by V. Altov / ibid., Which I take as a prototype. It contains a pole, on which a ring with a bag for fruits is fixed, and a second ring, covered with a net, movable on an axis, spring-loaded to the first. To capture the fetus, it is necessary to take the second ring away from the first with the help of a rope. Then, in the resulting solution, bring the fetus and release the rope. The seized fetus breaks off with a pole rod.

The disadvantage of this stapler is that it cannot cut the stalk when the fruit is firmly held on a branch.

Disclosure of the invention.

The aim of the invention is the manufacture of a fruit puller, which without difficulty captures a fruit located relative to the picker anywhere in the crown, makes it torn off or cut, accumulates and unloads them without damage.

This goal is achieved in that the upper ring is mounted on two V-arr. levers with an axis, a spring are retracted upwards with the possibility of being driven by a rope with rings fixed on it, strung on a pole, while the lower edge of the upper ring tightly intersects the upper edge of the fixed ring and forms scissors for cutting the stalk.

A brief description of the drawings.

The implementation of the invention.

The fruit picker contains a housing 1 in the form of a tube with an eye, on which a lower ring 2 of a strip of sheet steel with a variable height is fixed so that the front of the ring 2 has a smaller size, which facilitates the insertion of a ring between paired fruits without damaging them. A series of holes were drilled along the lower edge of ring 2, through which drive 3 was sewn, the lower end of which was tied with cord 4 to pole 5.

The movable ring 6 covers the ring 2 and only in the cutting zone it intersects tightly with it, forming scissors. Ring 6 is rigidly connected to the left and right V-arr. levers 7 and 8, which are connected through the holes in them to the housing 1 by the axis 9. On the axis 9 there is a spring 10, under the action of which through the pin 11 the upper ring 6 is always lifted up, forming a solution a with the lower ring 2, sufficient to capture large fruits . It is set by the angle between the shoulders of the V-arr. levers, the lower of which, when the upper ring 6 is raised, rest on the lower edge of the ring 2. A cap 12 is sewn to the upper edge of the ring 6. Its convexity should be sufficient so as not to prevent the stem 13 from being brought closer to the convergence point of rings 2 and 6, where the most its easy cutting. Through a flexible loop 14, a drive cable 15 is attached to the lower shoulders of the levers 7 and 8, on which rings 16 are fastened, strung on a pole 5. The number of rings is determined by the length of the pole and the distance between them, convenient for hand interception at different locations of the fruits in height.

Work as a fruit picker as follows. First, the fetus is inserted into the open solution a between rings 2 and 6. Then, as it is more convenient, rotate the fruit puller in one direction or another until the stem 13 comes closer to the beginning of the ring solution. After that, holding the closest ring 13, pull the rope 15, while the upper ring 6 slides along the upper edge of the stationary ring 2 when lowering it with the lower edge, cuts the stem 13. The cut fruit covered by the drive 3 gradually drops down. Unloading of fruits is carried out by overturning the fruit extractor. In this case, the fruits are unloaded without damage. In practice, depending on the ripeness, not every fruit needs to be cut.
