Description

one

This invention relates to universal hydraulic excavators.

A working equipment of a hydraulic excavator is known, including a boom, which are pivotally connected between themselves handles with buckets and power cylinders.

1. The disadvantage of the known equipment

is the unchanged parameters (radius n of the depth of the horse), which reduces the productivity of the excavator, for example, when extracting shallow tranches or when developing low faces.

The aim of the invention is to increase the performance of an excavator by changing the parameters of the equipment depending on the required operating conditions.

To do this, a slider is mounted on the arm, which is pivotally connected through a power cylinder and an additional link with an arrow.

FIG. 1 shows schematically an excavator, a sheath, its form; in fig. 2 - slider with locking device.

Work equipment includes boom

1, hinged to the base gear and driven in a cylinder motion

2. A booster joint 3, made in a boom extension driven by a cylinder 4, is attached to the boom tip of the boom. Slider 5 is pivotally connected to the addi- tional link 3 and the cylinder 6 hinged on it. 7 and stop in any part of it. Aid of the fixing device 8. To the main handle 7, the additional handle 9 is hinged with its top part. The handle is closed and opened by the power cylinder 10, which is The end is pivotally fixed in the lower part of the additional arm 9, and the other in the upper part of the main arm 7. On the lower parts of both handles the bucket 11 and 12 are hinged and driven through a system of t g power cylinders 13 14. The 14th slide, 16, and 17 of the slide 5 serve, respectively, for jibing the boom extension 3, the double arm 18 n of the power cylinder 6, on the boom extension 3, there is an emphasis 19 on the induction sensor 20. The larger arm of the two arm at the end It takes the shape of a plug and removes it when it is fixed odpruzhinenny pin 21 from the slot in the handgrip. The metal plate 22 of the inductive sensor 20 is undiased on the lug 16.
