Description

(54) ROTARY METAL

one

The invention relates to the field of mechanical engineering and can be used to transport material, such as soil, from cutting tools of earthmoving machines.

A rotary thrower is known, which at the same time is a rotary working body of a digging machine, consisting of a rotating shell with cutters on the end surface and a discharge device made in the form of an inclined plane fixed in the upper part of the shell and cutting off the ground 1.

The disadvantages of such a rotary scoop are the inability to use it for transporting material, such as soil, from other types of cutting tools of earthmoving machines, ejecting material in different directions from the axis of rotation and changing the range of material ejection.

A rotary thrower is also known, which includes a fixed frame, a rotor made in the form of an open from one end of the drum, a side shield, a guide plate and a drive 2.

The disadvantage of this thrower is the absence of the possibility of ejection of the material in different directions from the axis of rotation and a change in the distance of ejection of the material.

The purpose of the invention is to ensure the release of material in different directions from the axis of rotation of the scoop and the change in the distance of ejection of material.

This is achieved by the fact that the guide plate is attached to the bracket pivotally with the possibility of rotation and fixation in different positions relative to the rotor face, and the bracket of the guide plate and

The side flap is rigidly connected to each other and pivoted with the possibility of fixation with respect to the fixed frame. In addition, the rotor shaft is provided with a friction element interacting with the hub of the guide plate bracket.

FIG. 1 shows a rotary thrower in the position of long-distance emission of the transported material; in fig. 2 - the same, top view; in fig. 3 shows section A-A in FIG. one; on

FIG. 4 - rotary thrower in the position of ejection of the material to the left for the minimum distance; in fig. 5 - rotary thrower in the position of ejection of the material to the right for the minimum distance.

The thrower consists of a fixed frame l, a rotor 2, made in the form of an open drum at one end, an inferior-round side flap 3 mounted on a fixed frame with the ability to rotate

around the axis of the rotor on the guides 4 and 5,

a bracket 6 with a hub 7 mounted on bearings on the rotor shaft 8 and in a fixed frame, links 9, rigidly fastening the side shield with the bracket, the clamp 10, connecting the hub flange of the bracket with the fixed frame, the guide plate 11 mounted on the bracket rotatably around the axis of the bracket and locking in the desired position by the clamp 12, the flange 13 of the rotor shaft, the bracket 14 attached to the fixed frame, a tapered roller 15 mounted in the bracket rotatably and axially moving, ruzyne 16, the pressing roller cone to kronschteynu, cartridge 17 mounted on the finger bracket 18 rotatably around the pin, the insert arm 19.

During operation, the bulk material 20 is loaded into the rotating rotor 2 in the loading zone a. Once on the rotor side, the material gains speed from it and, being pressed by centrifugal forces to the side, begins to rotate along with the rotor. After meeting with the guide plate 11, located under the shell at an angle to the rotor face, the transported material changes its direction of movement and leaves the thrower in the place where the side shield 3 is not in free flight to the blade.

If it is necessary to eject the material being transported, the latch 12 is turned in the opposite direction, the guide plate AND is turned into a symmetrical position, the lock is in this position and the rotor is reversed.

To change the ejection range of the material transported by the thrower, the side flap 3 and the bracket 6 are rotated at an appropriate angle.

To rotate the flap 3 and the bracket 6 in large-sized throwers, where considerable effort is required, the torque of the rotor shaft is used. For this, the rotor 2 is rotated, the latch 10 is removed, the lever 19 is inserted into the cartridge 17 and the lever

overcoming the force of the spring 16, a taper roller 15 is inserted between the flanges of the hub 7 and the rotor shaft, thus creating a frictional bevel gear. At the same time, the torque from the rotor shaft is transmitted through the friction bevel gear to the hub of the arm 6, turning the guide plate 3 to the desired angle. Then remove the lever 19 and fix the required

the position of the latch 10. After removing the lever 19, the spring 16 returns the tapered roller 15 to its original position. By changing the force applied to the lever 19, the smoothness and precision of the turn of the side and guide plates is ensured.
