Изобретение относитс к сельскохоз йственному машиностроению, в частности к подборщикам хлопка-сырца.FIELD OF THE INVENTION The invention relates to agricultural machinery, in particular to raw cotton pickers.

Известен подборщик хлопка, содержащий бесконечные ремни, огибающие ведущий и ведомый щкивы, и нож дл очистки поверхности ведущего щкива, размещенный между ветв ми ремней 1.A cotton picker is known that contains endless belts, envelopes of the drive and driven shchiki, and a knife for cleaning the surface of the drive shchiv, located between the branches of the belts 1.

В этом подборщике нож не выполн ет свои функции по очистке поверхности ведущего шкива от налипщего технологического продукта (хлопок-сырец, сорна растительность , ветки и кусты хлопчатника, влажна земл и др.).In this pick, the knife does not fulfill its function of cleaning the surface of the drive pulley from the adhering technological product (raw cotton, weed vegetation, branches and bushes of cotton, wet soil, etc.).

Цель изобретени - повышение эффективности очистки поверхности шкива от налипшего технологического продукта.The purpose of the invention is to increase the efficiency of cleaning the pulley surface from the adhered technological product.

Это достигаетс тем, что нож выполнен из отдельных по длине элементов, установленных на общем основании касательно к поверхности шкива, причем лезви элементов ножа расположены выше линии контакта ножа с поверхностью щкива на величину, не более 1/10 радиуса щкива.This is achieved by the fact that the knife is made of separate lengthwise elements mounted on a common base with respect to the pulley surface, the blades of the knife elements being located above the line of contact of the knife with the surface of the knife by an amount less than 1/10 of the radius of the knife.

На фиг. 1 изображен подборщик, общий вид; на фиг. 2 - то же, вид в плане;FIG. 1 shows a pick-up, a general view; in fig. 2 - the same plan view;

на фиг. 3 схематически изображена установка ножа относительно щкива.in fig. 3 schematically shows the installation of the knife relative to the cheek.

Подборщик хлопка имеет ведомые 1 и ведущий 2 шкивы уборочного аппарата, на которых установлены уборочные ремни 3.The cotton picker has driven 1 and leading 2 pulleys of the harvester, on which the harness belts 3 are mounted.

Ведомые шкивы 1 независимо друг от друга качаютс в вертикальной плоскости на поводках 4 вокруг оси 5. При подъеме уборочного аппарата в транспортное положение поводки 4 опираютс на ось 6. С наружной поверхностью ведущего шкива 2The driven pulleys 1 independently of each other swing in a vertical plane on the leads 4 around the axis 5. When the harvesting machine is raised to the transport position, the leads 4 rest on the axis 6. With the outer surface of the driving pulley 2

контактирует установленный по касательной к ней нож, выполненный из отдельных по длине элементов 7, которые закреплены на общем основании 8. Лезви 9 элементов ножа расположены выше линии их контакта с поверхностью шкива на величину, не более 1/10 радиуса шкива.contacts a knife mounted tangentially to it, made of separate elements 7 along the length, which are fixed on a common base 8. The blades of the 9 knife elements are located above the line of their contact with the pulley surface by an amount not more than 1/10 of the pulley radius.

При работе подборщика ведущий шкив 2 прогибаетс (в пределах упругих деформаций ) от нат жени ремней. Кроме того, имеет место радиальное биение шкива (см.When the pick-up is operating, the drive pulley 2 bends (within the elastic deformations) from the tension of the belts. In addition, there is a radial pulley runout (see

Claims

FIG. 3). The elements 7 of the knife, each separately, are pressed against the surface of the pin, constantly copying it, due to its elastic properties. The location of the cutting edges 9 of the individual elements 7 of the knife above their line of contact with the surface of the pulley 2 makes it possible to produce an almost complete cut of the technological product and, moreover, to ensure a smooth guaranteed penetration of the surface of the pulley, which often has characteristic weld-welded electric welded pipes and in contact with the individual elements of the knife. This prevents jamming and breakage of the pick-up. Thus, the proposed knife provides a stable cleaning of the leading pulleys of the cotton picker belts and allows these machines to work with increased soil moisture. Testing of this device on quadruple cotton pickers showed that the cleaning of the driving pulleys from the adhered technological product is performed qualitatively and stably without breakage and jamming. This made it possible to bring availability and technological services to the level of agrotechnical requirements to increase the economic effect of the use of these machines. Claim 1. Cotton picker containing endless belts, envelopes of the driving and driven pulleys, and a knife for cleaning the surface of the driving pulley, placed between the branches of the belts, characterized in that, in order to increase the efficiency of cleaning the surface of the bump from the stuck technological product, the knife is made of individual elements of lengthwise mounted on a common base with respect to the pulley surface, the blades of the knife elements being located above the line of contact of the knife with the pulley surface: 2. A cotton bale according to claim 1, different yuschiys in that the knife blade elements are arranged above the blade line of contact with the pulley surface by an amount no more than 1/10 of the radius of the pulley.
