Abstract

Изобретение относитс к техническим средствам дл проведени мелиоративных работ, в том числе в малых регионах, а именно к маши :ам дл ремонта, прокладки и ухода за осушительными каналами и кюветами. Цель изобретени - упрощение конструкции, уменьшение габаритов в транспортном положении и повышение надежности . Мелиоративна машина включает базовый трактор 1, на раме 2 которого смонтированы рабочий орган (РО) 3 на стреле 4, т ги 5 управлени непосредственно РО 3, которые имеют упругие элементы (УЭ) 6. На раме 2 закреплены ма тниковые рычаги 7, которые через т ги 9 соедин ют гидроцилиндры (ГЦ) 8 со стрелой 4. На раме 2 на рычагах 12 и 13 закреплен противовес 14, образующий с рычагами 12 и 13 па- раллелограммную подвеску. Т гами 16 рычаги 12, имеющие кривошипные пальцы 17, соединены с ма тниковыми рычагами 7. При переходе из транспортного положени ГЦ 8 стрела 4 с РО 3 перемещаютс влево, а бак-противовес вправо. При встрече с преп тствием РО 3 посредством УЭ 6 демпфируютс ударные нагрузки. При переводе в транспортное положение ГЦ 8 и УЭ 6 позвол ют достичь компактности складывани РО 3 и его стрелы 4. 2 ил. S (ЛThe invention relates to the technical means for carrying out land reclamation work, including in small regions, and specifically to machines for the repair, laying and maintenance of drainage channels and cuvettes. The purpose of the invention is to simplify the design, reduce the size in the transport position and increase reliability. The ameliorative machine includes a base tractor 1, on the frame 2 of which the working body (RO) 3 is mounted on the boom 4, and the controls 5 directly control the PO 3, which have elastic elements (CI) 6. On the frame 2, the rotor levers 7 are fixed, which The glands 9 connect the hydraulic cylinders (GC) 8 to the boom 4. On the frame 2, on the levers 12 and 13, a counterweight 14 is fixed, forming a parallelogram suspension with the levers 12 and 13. T gami 16, the levers 12, having crank pins 17, are connected to the math levers 7. When moving from the transport position of the HZ 8, the boom 4 with the PO 3 is moved to the left and the tank counterweight to the right. When meeting with an obstacle PO 3 by means of UE 6, shock loads are damped. When transferred to the transport position, HZ 8 and UE 6 allow for a compact folding of the RO 3 and its boom 4. 2 Il.

Claims

Claim

The reclamation machine, including the base tractor and working equipment located on frame 5, has an arrow, a working body, a control link for the working body, a mounting beam for the working body, a movable counterweight and hydraulic cylinders for controlling the boom and counterweight, characterized in that, in order to simplify the design , reducing the dimensions in the transport position and increasing reliability, the boom is connected to the hydraulic cylinders of its rotation by means of articulated rods for controlling the boom and the pendulum lever, while the counterweight is connected to the frame by means of a parallelogram suspension, one of the links of which is equipped with crank fingers, the latter being connected to the pendulum levers by means of counterbalance control rods made with eyes for interacting with crank fingers and their relative movement, while the boom is equipped with a stop for interaction with the attachment beam of the working body , and the control rod of the working body is equipped with elastic elements.
