Description

Widely known rotary excavators of various designs, with or without a retractable rotor boom, driven by devices, placed on the counterbalance boom rigidly mounted on the turntable and serving whenever possible simultaneously as counterweights. However, raising and lowering the rotor boom in such excavators is difficult, and the operation of the cables supporting it is very difficult.

In the described excavator, these drawbacks are eliminated by the fact that a shtanga rod is hinged to the right angle of a hard triangle that forms the rotor boom, and the free end is mounted on the trolley moving along the path laid on the counterweight boom. To the same corner of a hard triangle can be attached pivotally to a ha of a carpet frame, the other end of which is also attached pivotally near the rotor. The end of the bucket frame, protruding into the interior of the excavator, rests on a mobile carriage moving along the path in front of the counterbalance boom. The same angle of the triangle forming the boom of the rotor can be pivotally connected to the pull rod, hinged at the end of the counterbalance boom. And in this case, the end of the bucket frame protruding inside the excavator rests on the carriage moving along its paths. The boom of the rotor can be moved by means of a cart

No. 142220- 2 ways, but the rod, through the other carriage in its own way, and these movements can be made at the same time, but independently from each other. An excavator can be used in which all sides of the counterweight triangle are connected by hinges. The KOBUfbteoH frame and the mast are also articulated, at the end of the TYPOVYRA5: y; e (u is the cart and the cart is at the end of the bucket frame of the other, and both carts are mixed by the counterbalance boom. Moving the cart on which the end of the bucket frame rests can be curved.At the boom of the excavator counterweight, a movable counterweight is mounted and the crane balancing both carts moves in one direction or the other depending on the direction of movement of these carts.

The drawing shows a diagram of the described rotary excavator.

The rotor excavator consists of a bucket frame /, forming together with a pull 2 and mounted on a platform 3, turning relative to the chassis 4, a mast 5, a hard triangle b, to the angle 7 of which a rod 8 is hingedly attached to the boom 9 by a driving carriage 10 moving along the path // laid on the boom 9 and forming together with the boom 9 and the mast 5 a triangle 12, a crane 13, a balancing carriage 10 and 14, of which the latter moves along the path 16 located in the front part of the boom 9, and carries the end of the bucket 17 ama / associated scharnirno at point 15 with draft type 2, the rotor 18, the boom of which is rigid triangle 6 and the counterweight 19, an arrow 9 peremeschayuschegos.

A change in the position of the rotor 18, such as its rise or fall, is carried out by moving the carriage 10 along the boom 9 and the carriage 14 along the tracks 16, which may have curvilinear outlines. The resulting shift in the center of gravity position is compensated for by appropriate displacement of the counterweight 19 and the crank. 13, carried out jointly or separately.

The described excavator allows to simplify the process of maneuvering the working body, which increases productivity and facilitates the maintenance and management of the maschina.
