Abstract

The invention relates to earthmoving machinery and m. used to develop trenches and pits. The goal is to increase the reliability of work by facilitating the transfer of the slopes when changing the equipment operation. The working equipment of the earthmoving machine consists of: a working device, mounted on frame 1, the thrower and knife retractors 4. The hinged communication unit of the upper end of the retractor 4 with frame 1 is made of a bracket (K) 5 with a supporting platform 6 and a finger 7. Each from retractors 4 has a locking mechanism. It is made of Heg from a spring-loaded axle 8 installed on frame 1 with a wedge 9 and a grip 10. The wedge 9 is installed with the ability to interact with the 6 K 5 bearing pad. When preparing the machine for trench operation, the blades of the backsides 4 are rotated to the lower working position and fixed -: are wedge 9. When the machine is prepared for work in the mode of digging gaps and pits by turning the trunnion 8, the wedge is removed from fixation and rotates together with the grip 10.

The invention relates to earthmoving machinery, namely, working equipment for the development of trenches and trenches.

The purpose of the invention is to increase the reliability of work by facilitating the transfer of the slopes when changing the operating mode of the equipment.

in FIG. 1 shows the working equipment, side view i in FIG. 2 is a view A of FIG. 1. in FIG. 3 shows the node I in FIG. 1j see 4-view B j; r FIG. 3; in fig. 5 is a sectional view BB in FIG. in fig. 6 - section GG on

The working equipment of the earthmoving machine includes mounted on the frame 1, the working body 2, the thrower 3 and the knife slopes 4. The latter by the upper end through the brackets 5 with the supporting platform b are hinged to the frame 1 by means of fingers 7.

The axis of each finger 7 is parallel to the plane of the blade scrapers 4 and is located at an angle to the cutting edge of the damper, the vertical axis and the plane of rotation of the working member at the rate of alignment with the axis of the conical

When preparing the machine for digging the slots and the boiler by turning the trunnion 8, the wedge 9 withdraws from the locking position and rotates together with the hook 10 to the position where the gripping jaw is bent up. After that, the knife is shifted to the upper nerab position, the gripper 10 together with the foy 8, overcoming the force of the spring 12, pulls back and tilts onto the plane of the knife, thus fixing the retractors in position.

retirees when they are transferred from the working position to the non-working.

For fixation of the slopes 4 on frame 1, rotatable-spring-loaded pins 8, equipped with a wedge 9 and gripper 10, are mounted.

When preparing the machine for operation in trench mode, the blades of the backsts are turned to the lower working position and each of them is fixed by a wedge 9, which is inserted by turning the trunnion 8 into the split between the supporting platform.

The working equipment of the ground machine, including the frame, the working body, the thrower c and the knife shears, the upper ones of which are hingedly connected to the frame, are characterized by the aim of increasing the reliability of working by changing the mode of operation
