Description

Изобретение относитс к машинам дл разработки мерзлых и прочных грунтов.This invention relates to machines for the development of frozen and firm ground.

По основному авт.св. №375355 известно устройство дл рыхлени мерзлого грунта, монтируемое на базовой машине и включающее стойки с зубь ми, снабженными съемными наконечниками. Одна из стоек с зубом расположена над другой и смещена вперед по ходу движени базовой машины. Стойки с зубь ми смонтированы на базовой машине посредством телескопических т г, образукхцих шарнирный параллелограмм 1.According to the main auth. No. 3,735,55, a device for loosening frozen ground is known that is mounted on a base machine and includes racks with teeth provided with removable tips. One of the posts with the tooth is located above the other and is shifted forward along the movement of the base machine. Racks with teeth are mounted on the base machine by means of telescopic t g, forming a hinge parallelogram 1.

Недостатком известного устройства вл етс узка область применени , невозмоткность использовани при рыхлении грунтов в стесненных, услови х, а также при выполнении других видов работ, например захват и перемещение ст1 оительных материалов (тротуарна njWTKa, древесина и т.п.). Кроме того, известное устройство нельз использовать при измен ющихс грунтовых услови х (р азлична глубина промерзаии грунта; различна проч ,ность грунтов и т.п.).A disadvantage of the known device is the narrow field of application, non-withdrawal of use when loosening soils in cramped conditions, as well as when performing other types of work, such as capturing and moving structural materials (pavement njWTKa, wood, etc.). In addition, the known device cannot be used under varying soil conditions (the depth of soil freezing is different; the strength of soil is different, etc.).

Цель изобретени - расширение технологических возможностей устройства .The purpose of the invention is to expand the technological capabilities of the device.

Поставленна цель достигаетс тем, что в устройстве дл рыхлени мерзлого грунта Зсшн стойка снабжена верхними консольными бгшкгши, шарнирно соединена с передней стойкой посредством закрепленных на The goal is achieved by the fact that in the device for loosening the frozen soil, the stand is equipped with upper cantilever arms, pivotally connected to the front stand by means of

to верхних част х стоек кронштейнов и имеет расположенное в ее нижней части монтажное отверстие, а телескопическа т га св зана с задней стойкой посредством закрепленного to the upper parts of the arm racks and has a mounting hole located in its lower part, and the telescopic rod is connected to the rear rack by means of a fixed

15 на консольных балках кронштейна.15 on the console beams bracket.

Задн грань передней стойки и передн грань задней стойки выполнены с насечками.The rear edge of the front rack and the front edge of the rear rack are made with notches.

Рыхлитель состоит из передней 1 и задней 2 стоек, установленных на The ripper consists of front 1 and rear 2 racks mounted on

Claims

30 different levels and some distance from each other, which are articulated to each other using brackets 3 and 4. Console support beams 5 mounted parallel to the longitudinal axis of the ripper in the upper part of the rear rack 2 are mounted. The cantilever support beams 5 are connected via a bracket b with a telescopic thrust (hydraulic cylinder) 7 controls. Notches 8 and 9 are made on the rear edge of the front support 1 and on the front edge of the rear support 2. In addition, there are holes 10 in the front support 1 for fastening the ripper to the base machine (not shown), and at the bottom. the parts of the rear pillar 2 are the mounting hole I. And the distance L from the mounting hole 11 to hole B; bracket 4 must be such as to ensure that the horizontal support of the cantilever support beams 5 is in the working position when changing the ripper. The device for loosening the frozen ground works as follows. When the ripper is deepened, the rear pillar 2 interacts with the ground, and then the front pillar 1 enters the work. destruction of high strength soils. When the ground conditions change (change in the particle size distribution, strength, and t, p.) With the help of the control hydraulic cylinder 7, the angle of loosening of the rear pillar 2 changes, for particular soil conditions it is established the most rational. When developing soils of insignificant strength, the cultivator destroys it with one pillar — front 1, and the rear pillar 2 in this case is set in an inoperative position. When it is necessary to move piece construction materials and products (pavement tiles, wood, etc.), the latter are captured between the pillars 1 and 2, on which notches 8 and 9 are made. The products are transported using the chassis of the base machine, on which Mounted device. When moving bulk materials (a pallet with bricks), the ripper is relocated - the lower part of the rack 2 is installed in the bracket 3 using the mounting hole 11, and the bracket 4 rests on the rear face of the front rack 1. The control hydraulic cylinder 7 is removed, In this case the cantilever support beams 5 arranged horizontally in the working position, which ensures transportation of the necessary materials to a given object. Thus, the implementation of the ripper in the form of two racks located at different levels and pivotally interconnected, as well as the presence of cantilever support beams in the upper part of the rear pillar, make it possible to change the ripper in different operating conditions. Claim 1, Apparatus for loosening frozen soil by ed. No. 375355, characterized in that, in order to expand its technological capabilities, the rear rack is provided with upper cantilever beams, pivotally connected to the front rack by means of brackets fixed to the upper parts and has a mounting hole located at its bottom, with a telescopic bar connected to the rear rack by means of a bracket mounted on console beams

2. The device according to claim 1, characterized in that the rear face of the front pillar and the front face of the rear pillar are made with notches. Sources of information taken into account during the examination 1. USSR Author's Certificate No. 375355, class, Е 02 F 5/30, 1967 (prototype).
