Description

The invention relates to rotary traniiieihii .iM excavators with a working body in the form of a wheel with buckets and a conveyor belt, laid out shrnand; cool to the trench axis.

With known excavators, a bucket wheel (rotor) with a conveyor is mounted on the base of the excavator and is in such a state both in the transport and in the working machine. Therefore, the base of the excavator is affected by a large tilting moment from the weight of the bucket wheel with a conveyor, the weight of the soil to the reaction of cutting forces during the operation of the excavator, as a result of which it is necessary to introduce a special balanced base. When a tractor is used for an excavator, the latter must be completely disassembled and fundamentally altered the main components - lengthening the track, installing a new running gearbox, installing a new rotor drive gearbox, etc.

Known rotary trench excavators with a mounted working body also have the disadvantage that the tracks are copied by micro-terrain.

The rotary trench excavator, according to the invention, is mounted on the tractor base (1), which is the motor

:. A slave organ and source ;. What are the organs of what the organ (2) is the trajectory of the entity through the slider. .

. The hatching head of the R 2, is supported on the vertical chassis of the excavator, and the scraper (| st 1 of the body weight of the body is (5) g, by the coil (6).. ...

The transfer part of the working body of the slider slider I) moves along the vertical posts (4) up and down by means of the chain C) of the hydraulic cylinder (8). The rear part of the working body is also lowered and assembled at the center of the hydraulic slide support (5).

The working body of the excavator consists of KosniOBorn wheels (rotors) (9) with buckets (10), frame (11), support and guide rollers (12), rear support (5), conveyor (13).

The rotor is supported and guided by four pairs of rollers (12), the axes of which are fixed on the size of the working body. The two front upper rollers (14) are at the same time also equipped with gears that transmit the rotation of the rotor through the slatted grip fixed to the rotor.

The rotation of the drive sprockets is carried out from the gearbox (15) by a two-way articulated transmission (16).

Ejection of the saddle from the inside floor; stop 1 of the rotor

The back support (5) of the working body consists of a frame (17), a hydraulic cylinder (18), a lifting rod (19), a rotary bracket (20), an ear (6), a selection shield (21), a clamp (22) and a lifting and lock pin (23).

The lift / lift rod (19) is carried out with the help of the hydraulic / hydraulic gear (18). and lowering the rear end of the tool in the process of cutting the rotor into the ground and leaving the trench. After lifting, the tool is mounted on the retainer (22) to unload the hydraulic system.

During the digging process, the rear leg moves along the trench. The selection board (21) is moved up and in on the rollers (24), which is necessary for the ego to penetrate the roter into and serve to clean up the trench from the ground and the buckets.

The sweep from the power take-off shaft: The tractor's power is transmitted to the power take-off box, which consists of molten corn (25) and the bottom of the shafts (26) and (27). At the end of the in-dl (20), a pole (28) is installed, which is in permanent engagement with the TWO gears (29) and (30), freely mounted on the shaft (27). I-change ;; Directions in the rotor's growth are produced by a cam clutch (31), which are taken from the excavator cabin by means of a coil. An oil (32) with a start clutch (33) is installed on the lower part of the power take-off housing.

Impl .: Driving the drive of the excavator and conveyor from the shaft of the tractor's power output is shown in the kinematic diagram.

From the shaft (34) of the tractor's power takeoff, rotation is transmitted to the power take-off box (35). From the power take-off via the driveshaft (36), the rotation is transmitted to the gearbox (15) of the rotor drive.

From the rotor drive reducer through a two-sided chain and transfer (16), the rotation is transmitted to the split drive shaft (37) of the rotor (9). The rotor receives in G; a groove from the leading gears (14), which are attached to the gauge with a gear peii 38.

The drums (39) of the belt conveyor receive movement from the conveyor drive reducer (40) through a chain drive (41). In order to carry out the working xoia of the excavator, an additional reduction gear is introduced into the tractor's gearbox. The hydraulic excavator control system is shown in the hydraulic circuit.

A hydraulic pump (42) is installed to lift the front and rear parts of the implement, which receives rotation from the power take-off.

The oil from the tank (43) is fed through a non-return valve (44) to the spool valve (45), which has two sections. By turning on one of the sections, the distribution: tel oil is leveled either into the cylinder (S) of lifting the front part of the working organ, or the cydihedron (18) in the days of supporting the pao / s body. The hydraulic control system is produced from the cabin of the excavator's laziness.
