Description

Изобретение относится к области сельскохозяйственного машиностроения, в частности к хлопкоуборочным машинам.The invention relates to the field of agricultural engineering, in particular to cotton machines.

В основном авт. св. № 628845. описан хлопкоуборочный аппарат, содержащий барабаны с установленными на них шпинделями, имеющими нижнюю зубчатую часть и верхнюю - гладкую, и технологическиещитки, огибающие только определенную часть окружности барабана, то есть на участке между зоной взаимодействия с кустом хлопчатника и зоной съема хлопка со шпинделей. При этом в зонах взаимодействия с кустом и съема барабаны открыты на всю высоту шпин- _J5целей. Нижняя зубчатая часть шпинделей служит для сбора хлопка с наиболее ценных нижних коробочек, а верхняя гладкая часть - для лучшего завода кустов в аппарат. _м Mostly aut. St. No. 628845. A cotton picking apparatus is described, comprising drums with spindles installed on them, having a lower gear part and an upper part being smooth, and technological shields that envelope only a certain part of the drum circumference, that is, in the area between the interaction zone with the cotton bush and the cotton picking area from the spindles . At the same time, in the areas of interaction with the bush and pick-up, the drums are open to the entire height of the spin- _J5 targets. The lower gear part of the spindles serves to collect cotton from the most valuable lower boxes, and the upper smooth part - for the best plant bushes in the apparatus. _m

Известно, что при вращении шпиндельных барабанов по всей их высоте возникают аэродинамические воздушные потоки, направленные в сторону вращения.It is known that when the spindle drums rotate along their entire height, aerodynamic air flows arise, which are directed in the direction of rotation.

Вследствие этого часть сорных примесей, особенно мелких, трудно отделимых при очистке, выделяющихся при воздействии на кусты хлопчатника верхней гладкой части шпинделей, увлекается этими воздушными потоками и проносится в пространство между шпиндельными барабанами и огибающими их технологическими щитками. При подходе к зоне съема сорные примеси падают вниз и попадают _ на снимаемый с нижней зубчатой части шпинделей хлопок-сырец, из-за чего увеличивается засоренность этой наиболее ценной части сырца.As a result of this, part of the weed impurities, especially small ones that are difficult to separate during cleaning, released when the upper smooth part of the spindles is exposed to cotton bushes, is carried away by these air currents and carried into the space between the spindle drums and the technological envelopes enveloping them. When approaching the pickup zone, weedy impurities fall down and fall _ onto the raw cotton removed from the lower gear part of the spindles, due to which the weediness of this most valuable part of the raw material increases.

Цель изобретения - снижение засоренности собранного хлопка-сырца.The purpose of the invention is the reduction of weediness of the collected raw cotton.

Указанная цель достигается тем, что каждый из барабанов, шпиндели которых имеют захватывающие элементы только в нижней части, снабжен цилиндрическим кожухом, охватывающим барабан по цуге вне рабочей зоны аппарата, высота которого соответствует высоте свободнойThis goal is achieved by the fact that each of the drums, the spindles of which have gripping elements only in the lower part, is equipped with a cylindrical casing covering the drum along the train outside the working area of the apparatus, the height of which corresponds to the height of the free

Аппарат содержит кустоподъемники 1, барабаны 2 с установленными на них шпинделями 3, имеющими нижнюю зубча- . тую часть и верхнюю - гладкую, барабаны 4 со шпинделями 5 с нарезкой зуба ю по всей их высоте, обслуживающие их съемники 6 и приемные камеры 7, Барабаны 2 вне эоны взаимодействия с кустом хлопчатника на длине гладкой части шпинделей полностью закрыты огибающи- и ми их кожухами 8, а барабаны 4 технологическими щитками 9 - лишь на участках между зоной взаимодействия с кустом и зоной съема.The apparatus comprises brush lifts 1, drums 2 with spindles 3 mounted on them, having a lower cog-box. this part and the upper part are smooth, drums 4 with spindles 5 with tooth cutting along their entire height, servicing pullers 6 and receiving chambers 7, Drums 2 outside the interaction zone with the cotton bush on the length of the smooth part of the spindles are completely enveloped by them casings 8, and the drums 4 technological guards 9 - only in areas between the zone of interaction with the bush and the removal zone.

Во время движения машины по полю кусты хлопчатника направляются кустоподьемниками 1 в рабочую зону аппарата между барабанами 2. Барабаны 2 вращаются в сторону, противоположную нап- 25 равнению движения машины. Шпиндели 3 в зоне взаимодействия с кустом хлопчатника вращаются в сторону, соответствующую направлению движения машины, и. нижней зубчатой частью захватывают 30 хлопок-сырец с нижних коробочек и наматывают на себя. Верхняя часть шпинделей 3 при этом способствует лучшему протягиванию кустов в аппарат за счет выполнения этой части гладкой. В зоне съема 35 ние вращения, происходит снятие съемником 6 хлопка, собранного нижней-зубчатой поверхностью , и перебрасывание его к приемной камере7. Выделяющиеся при воздействии на куст верхней гладкой части шпинделей 3 сорные примеси проносятся образуемыми при врДЩенйи барабанов 2 воздушными потоками по внутренней огибающей поверхности кожуха 8, полностью закрывающего гладкую часть шпинделей 3, в рабочую зону и падают на землю. Тем самым исключается попадание сорных примесей на снимаемый с нижней зубчатой части хлопоксырец. Оставшаяся на кустах Часть хлопка собирается барабанами 4 со шпинделями 5, имеющими нарезку зуба по всей их высоте.While the machine is moving across the field, the bushes of cotton are guided by bush lifters 1 to the working area of the apparatus between the reels 2. The drums 2 rotate in the direction opposite to the direction of movement of the machine. The spindles 3 in the area of interaction with the cotton bush rotate in the direction corresponding to the direction of movement of the machine, and. 30 cotton raw material from the lower boxes is taken up by the lower gear part and wound on itself. The upper part of the spindles 3 at the same time contributes to a better pulling of the bushes into the apparatus by making this part smooth. In the removal zone 35 rotation, the stripper 6 removes the cotton collected by the lower toothed surface and transfers it to the receiving chamber 7. Trash impurities released when the upper smooth part of the spindles 3 is exposed to the bush are carried by air currents generated by the drums 2 along the inner envelope of the casing 8, which completely covers the smooth part of the spindles 3, into the working area and fall to the ground. This eliminates the ingress of weed impurities on the cotton seed removed from the lower gear. Part of the cotton remaining on the bushes is collected by drums 4 with spindles 5, which have a tooth cut along their entire height.

FIELD OF THE INVENTION The invention relates to the field of agricultural engineering, in particular to cotton harvesting machines. St. No. 628845. describes a cotton-picking machine that contains drums with spindles mounted on them, having a lower tooth and a smooth upper part, and technological gates, enveloping only a certain part of the drum circumference, i.e. in the area between the interaction zone with the cotton bush and the area remove cotton from spindles. At the same time, in the areas of interaction with the bush and removal, the drums are open to the full height of the spindles. The bottom gears of the spindles are used to pick cotton from the most valuable lower bolls, and the top smooth part is for the best bush plant in the machine. It is known that when the spindle drums rotate along their entire height, aerodynamic air flows arise in the direction of rotation. As a result, a part of weed impurities, especially small ones that are difficult to separate during cleaning, released when the upper smooth part of the spindles are exposed to cotton bushes, is entrained by these air currents and is carried into the space between the spindle drums and the envelopes surrounding them. When approaching the Cbeiia zone, weed impurities fall down and fall onto raw cotton removed from the lower toothed part of the spindles, which increases the weediness of this most valuable piece of raw material. The purpose of the invention is to reduce the weediness of harvested raw cotton. This goal is achieved by the fact that each of the drums, the spindles of which have fascinating elements only in the lower part, is provided with a cylindrical casing covering the drum along an arc outside the working area of the apparatus, the height of which corresponds to the height of the free 379 from the sparring elements.
