(54) КАМНЕУБОРОЧНАЯ МАШИНА(54) STONE MACHINE

II

Изобретение относитс к сельскохоз йственному машиностроению, в частнрсти к машинам дл уборки камней.FIELD OF THE INVENTION The invention relates to agricultural machinery, in particular, to machines for cleaning stones.

Известна камнеуборочна машина, включающа установленную на ходовые колеса раму и последовательно смонтированные на ней с возможностью поворота наклонную гребенку с продольно расположенными зубь ми к бункер-накопитель .A stone harvesting machine is known, which includes a frame mounted on the running wheels and a sloped comb which is successively mounted on it with the possibility of rotation with longitudinally spaced teeth to the storage hopper.

Недостатком известной машины вл етс заклинивание камней между зубь ми гребенки, что приводит к нарушению процесса сепарации почвы.A disadvantage of the known machine is the jamming of stones between the teeth of the comb, which leads to disruption of the process of soil separation.

Цель изобретени - повьппение эффективности работы машины.The purpose of the invention is to improve the efficiency of the machine.

Указанна цель достигаетс тем, что машина снабжена дополнительной гребенкой с механизмом ее поворота, размещенной своими зубь ми в пространстве между зубь ми наклонной гребенки и св занной с последней посредством расположенного в ее средней части шарнира н механизма noBopoTajThis goal is achieved by the fact that the machine is equipped with an additional comb with its mechanism of rotation, which is placed with its teeth in the space between the teeth of the inclined comb and connected to the latter through the noBopoTaj mechanism located in its middle part

при этом верхн часть наклонной гребенки выполнена перфорированной, а зубь дополнительной гребенки снабжены пальцами, вход щими в перфорацию .the upper part of the inclined comb is perforated, and the tooth of the additional comb is provided with fingers included in the perforation.

На г. схематически представлена камнеуборочна машина, вид сбоку; на фиг.2 - сечение А-А на фиг.Ц I на фиг.З - схема заклинивани камней на фиг.4 - схема высвобождени камней.In the year, a stone harvesting machine is shown schematically, side view; Fig. 2 shows a section A-A in Fig. 3. I in Fig. 3 is a diagram of the seizure of stones in Fig. 4 a diagram of the release of stones.

Claims

The machine includes a frame 1 mounted on the running wheels 2, an inclined comb 3 with longitudinal teeth 4 pivoted by means of a hydraulic dial 5 around the hinge 6. In the middle part of the comb 3 there is a hinge 7, to which is attached an additional comb 8 with teeth 9 located between the teeth 4. The rotation of the additional comb 8 is carried out by the mezzanillum of rotation by the hydraulic cylinder 10 mounted on the comb X. The upper part 1I of the comb 3 is perforated, while in its perforation there are fingers 12 a comb 8. A storage hopper 13 is placed behind the comb 3 and is fixed on the frame 1 with the possibility of rotation with the help of a hydraulic cylinder 14. The axles of the wheels 15 are fixed on the axis of the wheels 15, on which the comb 3 rests. . The stops 15 are set to a certain depth of undermining of the comb 3. When the machine is moving, teeth 4 and 9, respectively, of the comb 3 and 8, are combing the soil layer. When the comb is filled with 3 stones, the cylinder 5 rotates it around the hinge 6. As the comb 3 rotates, the mass is poured together with the additional comb 8, while small stones and soil are sifted through the gaps between the teeth 4 and 9 and the space between the fingers 12 and the perforated part 11, and the stones are rolled into a bun-core drive 13, Kotopbni perform their periodic unloading. When the stones are stuck between the teeth 4 and 9, an additional comb 8 is rotated, the relative displacement of the teeth 4 and 9 occurs, as well as the fingers 12 exit from the perforation, as a result of which the stones are released and fall on earth. The use in the stone harvester of an additional rotary comb allows eliminating the seizure of stones and increasing, thereby, the effectiveness of its work. Claims of the stone harvesting machine, which includes a frame mounted on the running wheels and a sloped comb with longitudinally spaced teeth mounted on the running wheels and a storage hopper, which, 4TOj, in order to improve its performance, is equipped with an additional comb with its mechanism rotation, placed by its teeth in the space between the teeth of the inclined comb and connected with the latter by means of a hinge located in its middle part and a turning mechanism , while the upper part of the inclined comb is perforated, and the tooth of the additional comb is provided with fingers included in the perforation.
