Abstract

Изобретение относитс к сельскохоз йственному машиностроению, в частности к захватным устройствам дл вороха из стебельчатых растений, и может быть использовано дл подъема и транспортировани лозы и в технологических лини х дл ее переработки . Цель изобретени - улучшение эксплуатационных характеристик устройства . Устройство содержит закрепленные на основании 1 захватный элемент в виде спиральной пружины 2. св занной с приводом 3 ее вращени , фиксирующие стержни 4 с вертикальным 7 и боковыми упорами 8, обеспечивающими фиксацию центрального положени пружины в ее свободном состо нии и соскальзывание пружины при максимальном ее раст жении, привод щее к ее сжатию и как следствие встр хиванию подн того вороха и устранению таким путем посторонних предметов и земли. Стержни и пружина могут быть выполнены электропроводными и включены в схему сигнал о наличии в ворохе электропроводных включений. 3 з. п. ф-лы, 5 ил.The invention relates to agricultural machinery, in particular to pickups for a heap of stalked plants, and can be used for lifting and transporting the vine and in processing lines for processing it. The purpose of the invention is to improve the performance of the device. The device contains a gripping element fixed in the base 1 in the form of a spiral spring 2. associated with the drive 3 of its rotation, locking rods 4 with a vertical 7 and lateral stops 8, which fix the central position of the spring in its free state and spring out at its maximum. resulting in its compression and, as a result, shaking up the heap and eliminating foreign objects and earth in this way. The rods and the spring can be made electrically conductive and are included in the circuit signal about the presence of electrically conductive inclusions in the pile. 3 h. n. f-ly, 5 ill.

Claims

Claim

1. A gripping device for fibrous loads, mainly vines, comprising a base with a bracket fixed thereto, carrying a loop for hanging on a hook of a lifting machine, a gripping element made in the form of a spring fixed to the base perpendicular to its lower plane connected to its rotation drive, and fixing rods arranged parallel and concentric with respect to the spring, characterized in that, in order to improve operational characteristics, the fixing rods are made with a length not less than springs, and are equipped with one vertical with the orientation of the working surface down, and the other with side stops placed with the possibility of simultaneous interaction with the lower turns of the spring to fix the central position in its free state, with each of the side stops mounted on the corresponding rod with its upper position and lower ends with a vertical offset relative to the working surface of the vertical stop at a distance of not more than a longitudinal displacement of the coil in the gap between the first and each of second stops, respectively, with the free state and maximum tension of the spring.

2. The device pop. 1. The fact is that the spring and the fixing rods are electrically conductive, insulated from each other and included in the control circuit of the signaling device.

3. The device according to claim 1. The clause is that the spring in the upper part is made with a conical winding turning into a shank associated with the drive.

4. The device pop. 1, characterized in that it is provided with additional springs with different coil diameters fixed on the base concentrically to the main spring.
