RU2434099C1 - Roller of impact action 3 - Google Patents

Abstract

FIELD: machine building.

SUBSTANCE: roller of impact action 3 includes dynamic rotor consisting of interconnected rolling hollow tubes with working element secured on ends. A hammer is installed inside each pipe. The hollow tube proper and the hammer installed in it are designed for temporary attachment of the hammer for its rise at rotation of the roller, for release of the hammer in an upper position and its transfer inside the pipe downward. When the hammer drops, it strikes a back side of the working element. The dynamic rotor is installed inside a steel cylinder casing and rolls along internal surface of the casing in the direction perpendicular to geometric axis of the cylinder casing. The cylinder casing can be made solid, thru and equipped with lugs in roller of impact action 3. At progressive motion of a tractive unit the dynamic rotor rolls along internal surface of the cylinder casing and transfers the latter. Thus there are made periodic impacts against internal surface of the steel casing.

EFFECT: steel cylinder casing performs assigned operation under effect of impact.

Description

FIELD OF THE INVENTION

The invention relates to mechanical engineering and can be used in agriculture for tillage, for compaction of the soil during earthworks in construction and for the destruction of ice formations on roads and sidewalks.

State of the art

Known roller, including the axis of rotation of the roller, the plane of symmetry perpendicular to the axis of rotation of the roller, and the geometric surface of the roller of cylindrical shape acting on the surface to be treated (see, for example, the book. Construction machines. M .: Higher school, 1988, p. 210). A disadvantage of the known skating rink is the limited scope of its application, namely, the skating rink is used only for compaction of the soil during earthworks.

Known trailed roller shock (see RU patent for the invention No. 2365707, IPC E02D 3/046, E01C 19/41). The roller includes a longitudinal axis of rotation of the roller, a plane of symmetry perpendicular to the longitudinal axis of rotation, and the surface of the roller formed by the ends of the hollow pipes located along a helical line together with a device located on each end of the pipe containing a working body acting on the soil, made with the possibility of its limited linear displacement. All hollow pipes are rigidly interconnected with an angular displacement relative to each other, inside each pipe there is a hammer, and the hollow pipe and the hammer placed inside it are made with the possibility of temporarily securing the hammer at each end of the pipe to lift it when the roller moves, with the possibility of release hammer from fixing in the upper position and moving it inside the pipe down.

Disclosure of invention

Known trailed shock roller (Patent RU for the invention No. 2365707, IPC E02D 3/046, E01C 19/41) (hereinafter referred to as a dynamic rotor or simply a rotor), is placed inside a steel cylindrical shell (in a steel pipe).

The dynamic rotor consists of hollow pipes connected between the rolling elements with a working body fixed at the ends, a hammer is placed inside each pipe, the hollow pipe itself and the hammer placed in it are made with the possibility of temporarily securing the hammer to raise it when the roller is rotating, with the possibility of releasing the hammer from fixing in the upper position, its movement inside the pipe down and impact when the hammer falls on the back of the working body.

The axis of the dynamic rotor is connected to the tractor with the possibility of rotation of the rotor. With the translational movement of the tractor, the rotor rolls along the inner surface of the shell perpendicular to its geometric axis, which leads to rolling along the machined surface and the steel cylindrical shell itself. In this case, hammer blows periodically occur on the back of the working body, that is, on the inner surface of the steel shell. Undergoing impact from the inside, the outer surface of the steel cylindrical shell performs a given useful work. The surface structure of a cylindrical shell, depending on the task, may be different. In particular, it can be a smooth surface used in compaction of the soil, a grating, used in the tillage after plowing, a surface with external protrusions, used in the destruction of ice formations on roads.

The implementation of the invention

The shock roller 3 includes a dynamic rotor 1, consisting of hollow pipes 2 interconnected with each other with rolling ability and a working body 3 fixed at the ends, and a hammer 4 is placed inside each of the pipes, and the hollow pipe and the hammer placed in it are made with the possibility of temporary fixing the hammer for its rise during rotation of the roller, with the possibility of releasing the hammer from fixing in the upper position and moving it inside the pipe down, with the possibility of impact when the hammer falls on the back of the working body, and d namic rotor 1 is placed inside a steel cylindrical shell 5 in rolling manner along the inner surface of the shell in the direction perpendicular to the geometric axis of the cylindrical shell. The axis of the dynamic rotor 6 is connected by rods 7 with a tractor with the possibility of rotation of the rotor. End stops 8 are bolted 9 to a steel shell, and the diameter of the Central hole of the stops 8 eliminates their contact with the axis of the rotor 6 during a reactive rebound of the rotor from the impact of the hammer 4 on the inner surface of the cylindrical shell 5.

The steel cylindrical shell may be solid and have, for example, a smooth outer surface.

The steel cylindrical shell can be made through, for example, lattice structure.

The outer surface of the continuous cylindrical shell may be provided with protrusions, for example, may be made ribbed or provided with spikes.

Roller shock 3 operates as follows. With the translational movement of the tractor, the rotor rolls along the inner surface of the cylindrical shell 5 and the steel cylindrical shell rolls along the machined surface. In this case, hammer 4 is periodically dropped and hit on the back of the working body and hit on the inner surface of the steel shell. Undergoing a shock from the inside, the outer surface of the steel cylindrical shell 4 in motion performs a given useful work.

The surface structure of a cylindrical shell, depending on the task to interact with the surface to be treated, can be different. In particular, a smooth surface can be used for soil compaction, a trellised surface can be used for soil cultivation after plowing, and a surface with external protrusions can be used for the destruction of ice formations.
