Description

(5) METAL MATERIAL

one

The invention relates to building and transporting machines such as material throwers and is aimed at improving the reliability of the throwers.

A rotary thrower is known, which includes a frame, a rotor made in the form of an open drum at one end, a side and guide plates and an actuator, with the plates being rotatable so that they can be fixed relative to frame 1.

The disadvantage of this metal scoop is that the metal scoop gets jammed when stony inclusions get into it.

A rotary thrower is known that includes a frame with a rotor mounted on it, having a concave inner surface and a unloading mechanism, made in the form of a disk mounted on a radial bracket in the inner cavity of the rotor at an angle to the plane of its rotation 2.

The disadvantage of this scoop is that when fragments of material get between the inner surface of the rotor and the unloading device, the wedge wedges, which creates dynamic loads on the structural elements.

The purpose of the invention is to increase the reliability of the metatel.

The goal is achieved by the fact that in the material scoop, which includes a frame with a rotor mounted on it, having a concave inner surface and a unloading mechanism,

Claims (2)

15 made in the form of a disk mounted on a radial bracket in the inner cavity of the rotor at an angle to the plane of its rotation, the frame is provided with a sleeve rigidly connected to it, made with a guide groove angled to the plane of rotation of the rotor, and the radial bracket is connected a sleeve by means of a finger and is installed with the possibility of rotation. In addition, the radial arm is connected to the frame by means of an elastic member. FIG. 1 shows a thrower, a general view; in fig. 2 shows a section A-A in FIG. in fig. 3 view B in FIG. Thrower material contains a bladeless rotor 1, with a concave curved surface connected to the hub 2, on which drive gear 3 is mounted. Hub 2 is installed with the help of the bearings on the shank 5 of the sleeve 6 rigidly connected to the frame 7 throwers. An axle 9 is mounted inside the sleeve 6 by means of the PINS 8. The radial bracket 11 with the unloading device in the form of a disk 12 is mounted with the possibility of rotation in the axial direction by means of the hinge pin 10. The disk 12 is mounted on the radial bracket 11 with the possibility of rotation and position wives in the inner cavity of the rotor 1 at an angle to the plane of its rotation. The radial arm 11 is connected to the frame 7 by means of an elastic element 13, for example, tension springs (Fig. 1). In the sleeve 6, a through-groove 14 is formed at an angle to the plane of rotation of the rotor 1 (Fig. 3). bracket 11. In the leftmost position, the radial bracket 11 is mounted on the stop 15; The thrower works as follows; The material (as shown by arrow C) enters the internal cavity of the rotor 1, which is rotated in the direction of arrow D through gear 3, and is accelerated by act and the frictional forces of weight and centrifugal forces. When interacting with the disk 12 of the unloading mechanism located at an angle relative to the plane of rotation of the rotor 1, the flow of material changes the direction of movement and flies out of the thrower in the direction indicated by arrow D. In case of sticking of rocky inclusions between the inner surface of the rotor 1 and the disk 12 the forces acting on the radial bracket 11, the rotation increases and exceeds the torque provided by element 13 by the vn 74 element. The radial bracket 11 automatically rotates on axis 9 in the direction of rotation the torus 1, moving along the guide groove 1, and simultaneously rotates relative to the hinge pin 10 in the axial direction by an angle (Fig. 2), thereby outputting the disk 12 I8 of the internal cavity. Large stony inclusions, when the radial bracket 1 1 is rotated, are ejected by the disk 12 from the rotor 1. Small stony inclusions and fragments of material continue circular motion in the internal cavity of the rotor 1, evenly distributed over its surface under the action of centrifugal forces. Then, the radial arm 11, under the action of the elastic element 13, is rotated to its original position, at which the disk 12 provides for the ejection of material from the scoop. The advantage of the proposed thrower is the reduction of dynamic loads on the main structural elements and drive of the thrower, as well as the elimination of material jamming between the rotor and the disk of the unloading device, which eliminates the likelihood of structural failure. A preliminary assessment shows that when the scooper works on soils with rocky inclusions, the reliability of the proposed scoop construction increases by 20-35 or more compared to the prototype. Claim 1. Material thrower, including a frame with a rotor mounted on it, having a concave inner surface and an unloading mechanism, made in the form of a disk mounted on a radial bracket in the inner cavity of the rotor at an angle to the plane of its rotation, so that, in order to increase the reliability of the thrower, the frame is provided with a sleeve rigidly connected to it, made with a guide groove at an angle to the plane of rotation of the rotor, and the radial arm is connected to the sleeve by redstvom finger and rotatably mounted. 2. The thrower according to claim 1, wherein the radial arm is connected to the frame by means of an elastic element. Sources of information taken into account in the examination 973717 1.
