Description

(54) БОТВООТДЕЛЯЮЩЕЕ УСТРОЙСТВО(54) HANDLING DEVICE

Изобретение относитс к сельскохоз йственному машиностроению, в частности к устройствам дл уборки корнеплодов .The invention relates to agricultural machinery, in particular to a device for harvesting root crops.

Известно ботвоотдел ющее устройство , содержащее расположенные напротив друг друга встречно вращающиес роторы, состо щие Из ведущего и ведомого дисков, соединенных между собой параллельными планка -ш, с закрепленными на их концах цапфами, установленными посредством шарниров креплени Б гнездах упом нутых дисков It is known to have a topper-separating device containing oppositely rotating counter-rotating rotors consisting of master and slave discs interconnected by a parallel strap, with pins fixed at their ends, mounted by means of hinges for fastening the sockets of said discs.

Недостатки известного устройства , состо т в сложности монтажа и низкой эксплуатационной надежности.The disadvantages of the known device are the complexity of installation and low operational reliability.

Наиболее близким к предлагаемому вл етс ботвоотдел ющее устройство, содержащее расположенные напротив друг друга и установленные с возможностью встречного вращени механизмы шарнирных параллелограммов, сое- то щих из ведущего и ведомого дисков, соединенных между собой параллельными и наклонно установленными к оси вращени дисков планками с цапфами, размещенными посредством щарниров креплени в гнездах дисков 2 .Closest to the present invention is a topper separating device comprising opposite and located with the possibility of counter-rotating mechanisms of articulated parallelograms connected from master and slave disks interconnected by parallel and obliquely mounted to the axis of rotation of the disks with trunnions, placed by means of fastening joints in the slots of the disks 2.

Однако из-за больших габаритов шарниров креплени между смежными планками образуютс значительные зазоры, привод щие к ненадежному защемлению ботвы, ее проскальзыванию и, следовательно, некачествен10 ному отделению.However, due to the large dimensions of the hinge attachment, there are considerable gaps between the adjacent planks, resulting in unreliable pinching of the tops, its slippage and, consequently, poor quality separation.

Цель изобретени - улучшение качества отделени ботйы и повьщ1ение экеплуатационной надежности устройIS ства.The purpose of the invention is to improve the quality of the separation of the boty and increase the operational reliability of the device.

Указанна цель достигаетс тем, что Гнезда размещени шарниров креплени смеж1ных планок выполнены на противоположных торцах дисков с This goal is achieved by the fact that the jacks for placing the hinges of attachment of adjacent slats are made on opposite ends of the disks with

FIG., A side view of the device branch; in FIG. 2 the same, top view; in fig. 3 - a leading disk; in fig. 4, section A-A in FIG. 3; in fig. 5 section bb in fig. 1. The boom separating device contains opposite and located, with the possibility of counter-rotating mechanisms of the hinge parallelograms consisting of leading 1 and 2 and 3 and 4 disks interconnected parallel and obliquely mounted to the axis of rotation of the disks by slats 5 with trunnions 6, placed by means of fastening hinges 7 in the slots of 8 Disks 1-4. In this case, the nests 8 for locating the hinges 7 for fastening the adjacent strips 5 are made on opposite ends of the disks 1-4 with overlapping each other. The device operates as follows. When rotating the discs 1-4, the strips 5 move along elliptical trajectories, the axes of which are respectively S D and S Dsinc, where D is the diameter of the axes of the hinges 7 of the mount. Due to this, proceeding with the stimulation of the root crops for the tops to the stop with their heads into the lower surface of the slats 5, after which the bot is cut off. The quality of the separation of the tops is determined by the value D of the height difference of the slats 5 of the adjacent mechanisms of the hinge parallelograms. The smaller the value of the D / j height gradient, the closer to the head of the root and the better the separation of the tops. The disk 1 and 3 of one of the mechanics of the hinged parallelograms are turned relative to the disks .2 and 4 of the other, respectively, at an angle equal to half the angle between the axes of the hinges 7 in such a way that the strap 5 of the same mechanism of the hinge parallelograms. in the gap between the strips 5 other mechanisms. At the same time, the magnitude D of the height difference Gshank 5 of the adjacent mechanisms of the hinge parallelograms is approximately equal to half the value D 1g of the height difference of the adjacent planks of each mechanism of the hinge parallelograms. Due to the fact that the value D depends on the distance between the axes of the hinges 7 of fastening the adjacent strips 5 of the hinge parallelogram mechanism, the value of D is smaller, the smaller the distance between the said axes of the hinges 7. In the proposed device the reduction of the distance between The axles of the hinges 7 are achieved due to the fact that the sockets 8 are made on opposite ends of the discs 1-4, i.e. overlap and overlap each other. This makes it possible to install strips 5 on disks of smaller diameter, as a result of which the values of D and D are significantly reduced, and the height difference of the tops is correspondingly improved. In order to unify the parts entering the device, the leading disks 1 and 2 are rotated relative to the followers 3 and 4 at an angle equal to the angle between the sockets 8 1 for displacing the hinges 7 for attaching adjacent bars 5. The use of the proposed device improves the quality of the tops and increase its operational reliability. Claims of the invention: A boom-withdrawing device containing opposite-facing and installed with the possibility of counter-rotating mechanisms of the hinge parallelograms consisting of master and slave disks interconnected by parallel and obliquely mounted to the axis of rotation of the disks with pins attached by means of hinges of fastening in the nests of the discs, characterized in that, in order to improve the quality of the separation of the tops of the tops and increase the operational reliability of the device, the location of the hinge The mounting brackets of adjacent straps are made on opposite ends of the disks with overlapping each other.
