(54) ПОДБОРЩИК ХЛОПКА(54) COTTON PICK

1one

Изобретение относитс к сельскохоз йственному машиностроению, а именно к устройству дл подбора хлопка-сырца:The invention relates to agricultural machinery, namely, a device for the selection of raw cotton:

По основному авт. св. № 664603, известен подборщик хлопка, содержащий полый каток из упругоэластичного материала с 5 игольчатыми зацепами на наружной поверхности , съемник и кожух дл отсоса хлопка, на поверхности катка выполнены отверсти а кожух охбатывает верхнюю часть катка с возможностью образовани между кожухом и катком аспирационной камеры 1.According to the main author. St. No. 664603, a cotton picker is known that contains a hollow roller of elastic material with 5 needle hooks on the outer surface, a puller and a cover for sucking cotton, holes are made on the surface of the roller, and the housing covers the upper part of the roller to form an aspiration chamber 1 between the housing and the roller.

Недостатком известного подборщика вл етс мала активность игольчатых зацепов при подборе хлопка-сырца и неполный съем хлопка с зацепов за счет того, что они наход тс посто нно в одном положении. 15The disadvantage of the known pick-up is the low activity of the needle hooks in the selection of raw cotton and incomplete removal of the cotton from the hooks due to the fact that they are constantly in one position. 15

Целью изобретени вл етс повышение эффективности подбора и съема хлопка.The aim of the invention is to increase the efficiency of picking and picking cotton.

Поставленна цель достигаетс тем, что каждый игольчатый зацеп установлен в катке шарнирно и снабжен противовесом, раз- jo мещенным в полости катка, причем ось последнего имеет направитель установленный с возможностью взаимодействи с противовесами игольчатых зацепов перед зоной подбора хлопка.The goal is achieved by the fact that each needle hook is pivotally mounted in the rink and provided with a counterweight placed in the roller cavity, the axis of the latter having a guide mounted with the ability to interact with the counterweights of the needle hooks in front of the cotton picker zone.

На фиг. 1 изображен подборщик, поперечный разрез; на фиг. 2 - вид А на фиг. 1; на фиг. 3 - сечение Б-Б на фиг. 2.FIG. 1 shows a pick-up, cross section; in fig. 2 is a view A of FIG. one; in fig. 3 is a section BB in FIG. 2

Подборщик хлопка содержит установленный -на оси 1 каток 2 с отверсти ми 3 и игольчатыми зацепами 4, установленными с возможностью поворота посредством шарниров 5 и заглубленными внутри катка. На концах игл, внутри катка установлены противовесы 6.The cotton picker contains a roller 2 mounted on axis 1 with holes 3 and needle hooks 4 that are rotatably mounted by means of hinges 5 and recessed inside the roller. At the ends of the needles, counterweights are mounted inside the roller 6.

Над катком 2 установлен кожух 7, образующий аспирационную камеру 8, где создаетс всасывающий поток воздуха через отверсти 3 дл захвата хлопка 9. В аспирационной камере 8 концентрично поверхности катка 2 устаиовлена съемна гребенка 10. В нижней части перед рабочей зоной внутри катка 2 на валу 11 установлен направитель 12. Положение направител 12 регулируетс поворотом оси 1.A casing 7 is installed above the roller 2, forming an aspiration chamber 8, where a suction flow of air is created through the openings 3 to pick up cotton 9. A removable comb 10 is mounted concentrically on the surface of the roller 2. The lower part in front of the working area inside the roller 2 on the shaft 11 The guide 12 is installed. The position of the guide 12 is adjusted by turning the axis 1.

Подборщик работает следующим образом.Picker works as follows.

Claims

When the tractor is moving, the roller 2 rolls over the surface of the rows between the fallen raw cotton 9 and partially rigid objects. The hooks 4 are injected into the fallen cotton 9 and partially into the soil, while the counterweights are in the upper position. Upon further movement of the roller 2, the needle hooks 4 are released from adhering to the soil, and the counterweights 6 under the force of gravity are lowered down to contact with the inner surface of the roller 2, turning the hooks 4 with cotton, pressing the cotton against the outer surface of the roller, strengthening the gripping capabilities of the hooks, which increases the completeness of the selection. Upon further movement, the selected cotton enters the zone of action of the air flow R. The needles in the top position on the rink are always directed upward under the force of gravity of counterweights 6. When the roller 2 rotates, the counterweight 6 also has a centrifugal inertia force and the resultant force presses the counterweight 6 to the inner surface of the roller, thereby in the zone of removal of the needle is directed along the path of the air flow P, which removes cotton from the needle and carries it to the bunker. Some of the cotton fibers or kurak carried from the hooks 4 are moved to the comb 10. The comb 10 easily clears the hooks that are placed vertically under the action of the counterweight 6, and the cotton fibers stuck on the needles and the kurak are easily removed. Upon further movement of the roller, the counterweight 6 contacts the guide 12 at the point C, while the direction of the needle 4 gradually changes to the other side, and the point D of the guide 12 gives the needles 4 such a direction that the needles 4 in the pick-up zone enter the cotton 9 perpendicular rno When a needle 4 hits a stone, the weight of the counterweight 6 rotates around the hinge 5 and presses against the inner surface of the roller, thereby eliminating the breakage of the hook 4. Thanks to a more complete selection of raw cotton when it is effectively removed from the surface of the tool, the picker performance increases and the cost of cotton harvesting is reduced. Claims of invention Cotton picker by author St. No. 664603, characterized in that, in order to increase the efficiency of picking and picking cotton, each needle hook is pivotally mounted in the roller and provided with a counterweight placed in the roller cavity, the axis of the latter having a guide mounted with the ability to interact with the needle hooks in front of the pick zone cotton Sources of information taken into account during the examination 1.
