(S) ТЕРЕБИЛЬНЫЙ АППАРАТ (S) TERBAL DEVICE

Изобретение относитс к области сельскохоз йственного машиностроени , а именно к рабочим органам корнеуборочных машин.The invention relates to the field of agricultural engineering, namely to the working bodies of the root-harvesting machines.

Известен теребильный аппарат корнеуборочной машины, содержащий установленные на раме секции, включающие теребильные ремни, охватывающие ведущие и ведомые шкивы, боковины, соединенные рычажными разжимными механизг- JQ мами, рычаги которых одними концами закреплены по упом нутых боковинах а другими св заны общими ос ми flj.A top-harvesting unit of a root-harvesting machine is known, containing sections mounted on a frame, including top-lifting belts encompassing leading and driven pulleys, sidewalls connected by lever expansion mechanisms JQ Mami, the levers of which are fixed to the ends of one side and others connected by common axles flj.

Недостатком устройства вл етс то, что нат жение ремней осуществл етс is индивидуально путем перемещени каждого из ведомых шкивов, в св зи с чем возможно обеспечить с необходимой точностью равномерное нат жение обоих ремней, что вызывает их взаимное про- 20 скальзывание в рабочей зоне и приводит к уменьшению их срока службы. Кроме того, при перемещении ведомых шкивов увеличиваетс рассто ние между КОРНЕУБОРОЧНОЙ МАШИНЫThe drawback of the device is that the tension of the belts is carried out individually by moving each of the driven pulleys, and therefore it is possible to provide with the necessary accuracy the uniform tension of both belts, which causes them to slip through each other in the working area and causes to reduce their service life. In addition, as the driven pulleys move, the distance between the ROOT MECHANICAL MACHINE increases.

Цель изобретени - повышение качества тереблени путем обеспечени равномерногонат жени ремней.The purpose of the invention is to improve the quality of pulling by ensuring uniform belt dressing.

Это достигаетс тем, что аппарат снабжен расположенной вдоль секции направл ющей с установленным на ней с возможностью перемещени опорным элементом, на котором жестко закреплены общие оси рычагов разжимных элементов .This is achieved by the fact that the apparatus is provided with a guide along the section with a support element mounted on it with the possibility of movement, on which the common axes of the levers of the expanding elements are rigidly fixed.

На фиг. 1 изображен теребильный аппарат корнеуборочной машины, вид сверху; на фиг.-2 - разрез А-А на фиг. 1.FIG. 1 depicts a top-lifting elevator; FIG. 2 is a section A-A in FIG. one.

Claims

The shearing unit contains sections mounted on frame 1 of the machine, including belt 2, covering leading 3 and driven pulleys k, side 5, along guide section 6, and pressure rollers 7. Side walls 5 are connected by lever expansion mechanisms 8, arms 9 and 10 of which one ends are hinged on the sidewalls 5 and the other are connected by a common axis 11. The pressure rollers 7 and the driven pulleys are fixed on the sidewalls 5. The guide 6 is made T-shaped and has a supporting element on one side The device 12, on which the axis 11 of the levers 9 and 10 of the expansion mechanisms 8 is rigidly fixed, and on the other, the driving pulleys 3 are fixed by means of the brackets 13. The supporting element 12 is connected to the guide 6 by means of an adjusting device I (for example, a screw). . During the operation of the device, the belts 2 are pulled out, which leads to their slippage, unreliable seizure of root crops, and therefore the necessity of periodically adjusting the tension of the belts, 2. The tensioning process is carried out as follows. Through the adjusting device I, the supporting element 12 is moved along the guide 6. Simultaneously with the guide 6, the axles 11 fixed on it and connected to them by means of levers 9 and 10 of the side 5 move in turn through the driven pulleys k fixed on them tension Due to the hinged sidewall 5, an automatic uniform redistribution of the tension forces of the belts with different characteristics is made, which eliminates the possibility of lengthening, mutual relative slippage of the belts and increases the reliability of the process of wobbling of the root crops. When clogging the top-lifting apparatus, as a result of the ingress of a foreign body or a large amount of weed vegetation, sections are diluted with lever and expansion mechanisms 8 and the belts are cleaned.

2. Thus, the use of the device allows one straightening of two belts to be performed simultaneously with the same force, which reduces the labor costs for this operation by about two times and increases the service life of the belts. . Formula of the Invention Roofing machine of a root-harvesting machine, containing sections mounted on the frame, including terebel belts, covering the driving and driven pulleys, sidewalls connected by lever uncoupling mechanisms, the levers of which are fixed to the aforementioned sidewalls by one ends, and others are connected by common axes, characterized in that, in order to improve the quality of pulling by ensuring uniform tension of the belts, the apparatus is equipped with a guide along the section with a guide installed on it remescheni support element on which the common axis rigidly fastened. levers of expanding mechanisms.
