Device and process for the thinning of fruit tree buds

The invention relates to agriculture, namely fruit growing, particularly to a device and process for the thinning of fruit tree buds.The device, according to the invention, includes a main frame (6), equipped with four tubular crossbars (22) - two on the left and two on the right, telescopically connected by means of tubular elements (5) with two spars (3, 4), each of which is equipped with three working tools in the form of mobile bars (15), wrapped in synthetic rubber, mounted on axles (27) and connected from one end to fixed crossbars (14) by means of spiral springs (16), as well as with three supporting boards (17), a bearing roller (12 ) and a self-regulating wheel (18). At the same time, the main frame (6) is connected by a coupling annular shackle (7) to a secondary frame (8), telescopically connected by two cylindrical elements (23, 24) to two limiting boards (10), each equipped with two supporting boards (11) and is equipped with two beams (25) for attachment to the tractor frame.The process, according to the invention, consists in that in the period between 7 and 25 June, is carried out shaking of the fruit trees by three successive blows on the trunks at a height of 30...45 cm from the soil surface by the working members of a device, according to the invention, fixed in the frontal part of the tractor when it moves between the row-spacing of the fruit trees.The result is to provide for the thinning of fruit tree buds, combined with other technological operations carried out in the garden. Invenţia se referă la agricultură, şi anume la pomicultură, în special la un dispozitiv şi la un procedeu de rărire a fructelor abia legate ale pomilor.Dispozitivul, conform invenţiei, include un cadru principal (6) dotat cu patru traverse tubulare (22) - două de stânga şi două de dreapta, unite telescopic prin elemente tubulare (5) cu două lonjeroane (3, 4), fiecare fiind înzestrat cu trei organe de lucru în formă de bare mobile (15) învelite cu cauciuc sintetic, instalate pe axuri (27) şi unite la un capăt cu traverse imobile (14) prin intermediul unor arcuri elicoidale (16), precum şi cu trei plăci de reazem (17), o rolă de sprijin (12) şi o roată autoreglabilă (18). Totodată, cadrul principal (6) este unit printr-un cârlig inelar (7) de cuplare cu un cadru secund (8), unit telescopic prin două elemente tubulare (23, 24) cu două panouri de limitare (10), echipate fiecare cu două plăci de reazem (11), şi este dotat cu două grinzi (25) pentru fixarea de cadrul
