Description

Изобретение относится к сельскохозяйственному машиностроению, а именно к машинам для уборки камней.The invention relates to agricultural machinery, namely to machines for cleaning stones.

Известна камнеуборочная машина, включающая закрепленные на раме подбирающий ротор с зубьями и транспортер [1].Known stone harvesting machine, including mounted on the frame pick-up rotor with teeth and a conveyor [1].

Недостатком машины указанной конструкции является низкое качество вычесывания камней из почвы, так как в процессе работы ротора захватывает- ¹ся большое количество почвы, происходит ее сгруживание и заклинивание камней между зубьями, в результате чего снижается надежность выполнения технологического процесса. ¹ The disadvantage of said construction machine is a low quality combing stones from the soil, as during operation of the rotor ¹ zahvatyvaet- Xia large amount of soil, it occurs sgruzhivanie stones and jamming between the teeth, thereby reducing the reliability of performance of the process. ¹

Цель изобретения - повышение качества и надежности работы машины.The purpose of the invention is improving the quality and reliability of the machine.

Поставленная цель достигается тем, что машина снабжена, по крайней мере, одним дополнительным ротором, установленным вслед основному и имеющим В сравнении с ним меньший шаг между зубьями, при этом над каждым из рото2 ров размещено очистительное устройство , выполненное в виде вала с пальцами, вращающегося в противоположном относительно ротора направлении и с большей скоростью.This goal is achieved by the fact that the machine is equipped with at least one additional rotor installed after the main one and having, in comparison with it, a smaller pitch between the teeth, with a cleaning device made in the form of a shaft with fingers rotating over each rotor in the opposite direction relative to the rotor and with greater speed.

На чертеже схематически изображена предлагаемая машина.The drawing schematically shows the proposed machine.

Машина включает закрепленный на раме 1 подбирающий ротор 2 с изогнутыми зубьями 3, над которым размещено очистительное устройство, выполненное в виде вала 4 с пальцами 5, расположенными между зубьями 3. Сзади к ротору 2 примыкает прутковый транспортер 6 с решетчатым отражателем 7. Вслед ротору 2 установлен дополнительный ротор 8 с зубьями 9, расстояние между которыми выполнено меньшим шага между зубьями 3 впереди расположенного ротора 2. Над ротором 8 установлен вал 10 с. пальцами 11,The machine includes a picking rotor 2 mounted on the frame 1 with bent teeth 3, over which a cleaning device is placed, made in the form of a shaft 4 with fingers 5 located between the teeth 3. A bar conveyor 6 with a lattice reflector 7 is adjacent to the rear of the rotor 2. Following the rotor 2 an additional rotor 8 with teeth 9 is installed, the distance between which is made smaller than the pitch between the teeth 3 in front of the located rotor 2. A shaft of 10 s is installed above the rotor 8. fingers 11,

Валы 4 и 10 вращаются в противоположном относительно роторов 2 и 8 направлении и имеют большую скорость вращения и меньшее в сравнении с ними число рядов пальцев 5 и 11.The shafts 4 and 10 rotate in the opposite direction relative to the rotors 2 and 8 and have a higher rotation speed and a smaller number of rows of fingers 5 and 11 in comparison with them.

Камнеуборочная машина работает следующим образом.Stone-harvesting machine operates as follows.

При движении машины ротор 2 зубьями 3 извлекает из почвы камни и подводит их в зону действия очистительного устройства - вала 4, пальцы 5 которого, опережая зубья 3 ротора 2, снимают с них камни и перебрасывают их на транспортер 6. При этом камни, встречаясь на пути с отражателем 7, очищаются от налипшей почвы, которая просеивается сквозь зазоры решетки и прутковой поверхности транспортера 6.When the machine moves, the rotor with 2 teeth 3 removes stones from the soil and brings them into the zone of action of the cleaning device - the shaft 4, the fingers 5 of which, ahead of the teeth 3 of the rotor 2, remove stones from them and transfer them to the conveyor 6. At the same time, the stones meeting on paths with a reflector 7 are cleaned of adhering soil, which is sifted through the gaps of the grate and the bar surface of the conveyor 6.

Дополнительный ротор 8 работает аналогично ротору 2, однако его зубья 9 испытывают меньшее сопротивление почвы> поскольку грунт уже разрыхлен и из него удалены крупные включения.The additional rotor 8 works similarly to rotor 2, however, its teeth 9 experience less soil resistance> since the soil is already loosened and large inclusions removed.

Использование дополнительного ротора и очистительных устройств в схеме камнеуборочной машины позволяет увеличить ее надежность за счет исключения заклинивания камней и умень858595 4 шения нагрузки на зубья роторов, а также сохранить структуру почвы.The use of an additional rotor and cleaning devices in the scheme of a stone harvesting machine allows to increase its reliability by eliminating jamming of stones and reducing the load on the rotor teeth, as well as preserving the soil structure.

Claims

The invention relates to agricultural machinery, and it is referred to machines for cleaning stones. A stone harvesting machine is known, including a pick-up rotor with teeth fixed on a frame and a conveyor belt lj. The disadvantage of this design is the poor quality of stone extraction from the soil, since during the operation of the rotor a large amount of soil is seized, it is loaded and the stones are jammed between the teeth, resulting in a reduced reliability of the technological process. The purpose of the invention is to improve the quality and reliability machine work. The goal is achieved by the fact that the machine is equipped with at least one additional rotor installed after the main one and having an S mentality between teeth, comparing with it, with a cleaning device placed in the form of a shaft with fingers placed on each of the rotors opposite to the rotor direction and with greater speed. In the drawing cxej aTHuecKH shows the proposed machine. The machine includes a pick-up rotor 2 mounted on the frame 1 with curved teeth 3, above which there is a cleaning device installed in the form of a shaft 4 with fingers 5 located between teeth 3. A bar conveyor 6 with a lattice reflector 7 adjoins the rotor 2. the rotor 2 has an additional rotor 8 with teeth 9, the distance between which is made smaller than the pitch between the teeth 3 in front of the rotor located

2. Above the rotor 8, the shaft Yu is mounted with fingers 11, Shafts 4 and 10 rotate in the opposite direction relative to rotors 2 and 8 to have a greater rotational speed and a smaller number of rows of fingers 5 and a smaller number in comparison with them. The stone harvesting machine works as follows. When the machine is moving, the rotor 2 removes the stones 3 from the soil and brings them into the zone of action of the cleaning device - shaft 4, fingers 5 of which, ahead of the tooth 3 of the rotor 2, remove the stones from them and move them to the conveyor 6. When In this way, the stones, meeting on the way with the reflector 7, are cleaned of adhering soil which is sifted through the lattice gaps and the bar surface of the tranperter 6. The additional rotor 8 works similarly to the rotor 2, however, its tooth 9 experiences less soil resistance out of it Aleny large inclusions. The use of an additional rotor and cleaning devices in the circuit of the stone-harvesting machine makes it possible to increase its reliability by eliminating stone jamming and reducing the load on the rotor teeth, as well as preserving the soil structure. Claim 1. Stone-harvesting machine, including a pick-up rotor with teeth mounted on the frame and a conveyor, characterized in that, in order to improve the quality and reliability of operation, it is equipped with at least one additional rotor installed after the main one In comparison with it, a smaller step between the teeth, with a cleaning device placed above each of the rotors. Machine pop-1, characterized in that the cleaning device is made in the form of a shaft with fingers rotating in the direction opposite to the rotor and with greater speed.
