(54) РЫХЛИТЕЛЬ(54) RIDDER

1one

Изобретение относитс к землеройному оборудованию дл разработки мерзлых и разборно-скальных грунтов.The invention relates to earthmoving equipment for the development of frozen and rocky soils.

Известно рыхлительное оборудование с параллелограммным навесным устройством, включающим раздвигающеес звено, изменением длины которого обеспечиваетс поворот рабочей балки относительно поперечной горизонтальной оси и соответственно регулировка угла рыхлени 1.Known loosening equipment with a parallelogram hinged device, including a sliding link, by varying the length of which the working beam is rotated relative to the transverse horizontal axis and, accordingly, adjusting the angle of loosening 1.

Известен также рыхлитель, включающий базовую мащину, четырехзвенный механизм навески с верхней телескопической т гой и соединенной с т гой шарнирным пальцем рабочей балкой, гидроцилиндры подъема рабочей балки и закрепленные на последней рыхлительные зубь 2.Also known is the ripper, which includes the base machine, the four-link hitch mechanism with the upper telescopic rod and the working beam connected to the rod with a hinge pin, hydraulic cylinders for lifting the working beam and the loosening teeth 2 attached to the latter.

Недостаток этого рыхлител , также как и других, заключаетс в том, что его конструкци не обеспечивает рациональные углы рыхлени на разной глубине разрабатываемого материала (большие в начальный период заглублени , с уменьшением по мере заглублени и оптимальные - при установившемс рыхлении), величина которых определ етс физико-механическими свойствами грунта.The disadvantage of this ripper, as well as others, is that its design does not provide rational loosening angles at different depths of the material being developed (large in the initial period of dredging, with decreasing as it is dredging and optimal when steady ryhlenii), the value of which is determined physical and mechanical properties of the soil.

Цель изобретени - повышение производительности путем обеспечени выбора оптимальной траектории заглублени зубьев.The purpose of the invention is to increase productivity by ensuring the selection of the optimal trajectory of tooth digging.

Указанна цель достигаетс тем, что рабоча балка снабжена Эотементом перемещеg ни шарнира ее соединени с верхней т гой дл одновременного изменени их кинематических длин и выполнена с отверсти ми дл фиксации положени шарнира, пальцевым соединением.This goal is achieved by the fact that the working beam is equipped with an Eotement moving the hinge of its connection with the upper thrust to simultaneously change their kinematic lengths and is made with holes for fixing the position of the hinge with a finger connection.

Элемент перемешени шарнира выполн етс или в виде направл ющей опоры, вдоль которой расположены отверсти рабочей балки дл установки в них шарнирного пальца, или в виде коромысла с дополнительным фиксирующим пальцем дл установки в отверсти рабочей балки, которые The hinge mixing element is made either in the form of a guide support along which the working beam openings are located for installing a hinge pin in them, or in the form of a rocker arm with an additional locking pin for mounting into the working beam openings.

15 расположены концентрично оси соединени последней с коромыслом.15 are located concentric with the axis of connection of the latter with the beam.

На фиг. 1 изображен рыхлитель с элементом перемещени шарнира в виде направл ющей опоры; на фиг. 2 - то же, с 20 элементом перемещени шарнира в виде коромысла.FIG. 1 shows a ripper with a hinge displacement member in the form of a guide support; in fig. 2 is the same, with a 20 pivot element in the form of a rocker arm.

Claims

The ripper consists of a base machine 1 and a four-bar hinged device in the form of an upper telescopic cable 2, a lower cable 3, a working beam 4, a supporting frame 5 to the executive cylinders 6 for lifting the working beam 4. Tooth 7 is fixed on the working beam by 4 fingers 8. Working The beam 4 in one of the variants (Fig. 1) is made with a series of holes 9 located in the upper part, to one of which the upper telescopic rod 2 is pivotally attached with a finger joint with rollers 10 and with guide stops 11 for moving the rollers 10 through them. . In another In the embodiment (FIG. 2), the working beam 4 is made with holes 12 for fastening the rocker arm 13 with the locking pin 14. The upper telescopic rod 2 is moved relative to the working beam 4 remotely from the driver’s cabin using its hydraulic cylinders. For this, in the first embodiment, the fastening pin is removed in the working beam 4, in the second, the fixing pin 14 of the rocker arm 13 in the working beam 4. In the first variant, when the length of the string 2 is changed, its finger moves with movement of the rollers 10 along the guide stops 11 to combining with one of the holes 9 in the working beam 4, in the second embodiment, the rocker arm 13 is rotated relative to its axis of attachment in the ra, barreled beam until the pin 14 in the work beam 4 is aligned with one of the holes 12 of the rocker arm 13. Allowable change in kinematic lengths residues is articulated four-bar attachment (upper telescopic rod and working beams) provides be rational angles recessed teeth 7 into the ground. The installation of the most rational loosening angles ensures the quick introduction of teeth into frozen and rocky-rocky soils with different physical and mechanical characteristics and increases the average speed and depth of loosening, which generally leads to an increase in the productivity of loosening. Claim 1. A cultivator comprising a base cutter, a four-link linkage mechanism with an upper telescopic draft and a working beam connected to a hard joint with a hinge pin, hydraulic cylinders for lifting the working beam and fixed on the latter loosening teeth, characterized in that selection of the optimal trajectory of tooth digging, the working beam is equipped with an element for moving the hinge of its connection with the upper thrust for simultaneous change of their cinematic lengths and ying with holes for fixing the position of the finger scharnira compound. 2. A shredder according to claim 1, characterized in that the movement element of the hinge is made in the form of a guide support, along which the apertures of the working beam are arranged for installing a hinge pin in them. 3. A ripper according to claim 1, characterized in that the element of the joint hinge is made in the form of a rocker arm with an additional locking finger for insertion into the holes of the working beam, which are located concentrically with the axis of the joint connecting with the rocker arm.
