WITH

The invention relates to agricultural machinery, in particular to devices for harvesting fruit from trees.

The purpose of the invention is to increase the efficiency of use of a fruit picker.

In Fig.1 schematically presents the proposed bearer; Fig. 2 is a kinematic diagram of a cable system; Fig. 3 is a view along arrow A in Fig. 1; on ifg.4 - view along arrow B in figure 1; figure 5 - section aa in fig. 1; figure 6 is a section bB in figure 1.

The fruit carrier consists of a telescopic rod 1, the elements of which are provided with blocks 2. The upper element of the rod contains a cutting tool made in the form of a fixed comb 3, equipped with teeth in the form of knives 4,

which interacts with the movably mounted comb 5 with the cutting knives 6, held by the presser legs 7 and pivotally connected to the two-arm lever 9 mounted on the axis 8, the other end of which is connected to the tension spring 10. The lower element of the rod contains a drive consisting of a drum 11 s a handle 12 and a two-shouldered lever 13, on one side of which a block 14 is attached. and the other side is made in the form of a handle 15 for pressing by hand.

A cable 16 is wound onto the drum 11, one of the branches of which extends in a zigzag pattern along the blocks 2 of the rod constituent elements and is connected to the lower end of the upper element of the rod 1, and the second is passed in a zigzag pattern through the block 14 of the two shoulders of the lever 13, the block 17 of the lower element of the rod and

attached to the spring-loaded two-arm lever 9. The drum 11 of the cable drive is equipped with a stopper 18. as well as a fruit picker 19.

The lower element of the rod 1, in order to create a favorable appearance and ease of holding in hands, can be given a round shape by coating it with a non-metallic material.

The fruiting works, t as follows.

In the initial position, the telescopic cap of the ylang is folded, its components are lowered one into the other and are in the lower relatively elongated element (not shown in the drawing), which makes the fruit puller also convenient for transportation.

When the fruit is removed, the stopper 18 is released, the handle 12 rotates the scraper 11, as a result of which the upper branch of the cable 16 is pushed onto the barrel. The branch is tensioned and pushes the rod elements up until the lower block of the inner element It is at the same level as the upper block of the element, which is relative to it. The lower branch, the escape from the drum 11, allows the element of the rod with the cutting element to rise upward. Pushing out the barbell segments is carried out on the required spin, depending on the height of the tree or the tree from which the fruits must be removed. After that, the position of the drum 11 is fixed by the stopper 18.

The cutting body is brought to the fruits so that their stalks are between the teeth of the knife-comb combs 3, 5. By pressing on the handle 15, the block 14 deviates from its original position and pulls the lower branch of the cable 16. Since the upper branch of the cable 16 is on the locked drum 11, then the lower branch deflects the spring-loaded shoulder of the lever 9 downward, forcing the second shoulder and the movable comb 5 with the cutting knives 6 connected with it to move to the left. ayuts and fruits svalivayuts in Plo dosbornik 19.

The release of the handle 15 from pressing the hand leads the cutting tool to

initial position under the influence of the spring 10.

The extraction of fruits from the fruit picker 19 can be done in the traditional way - by tilting the staple to a convenient

recessing fruit height, or by folding an elongated bar. To this end, the stopper 18 of the drum 11 is released, as a result of which the drum is allowed to turn the handle 12 in the opposite direction

side. The lower branch of the cable 16 is tensioned and wound, and the drum 11 is not weakened and the upper branch descends from the drum. This allows the rod elements to move relative to one another,

reducing staff length and to february sizes. Further, the process of operation of the fruit extractor occurs according to the scheme described above.
