Technical Field

The invention relates to a coal mine belt cleaning system.

Background

Coal excavated in a mine is usually wet under the influence of low groundwater because the mine is usually at the bottom of the ground, and the pressure of the coal can be attached to a belt in the process of belt transportation, so that the belt is locally pulled for a long time, and the belt is damaged.

Disclosure of Invention

In order to solve the technical problem, the invention provides a coal mine belt cleaning system.

The invention is realized by the following technical scheme.

The coal mine belt cleaning system provided by the invention comprises a proximity switch, a controller and a hydraulic pump, wherein the controller is respectively connected with the proximity switch and the hydraulic pump;

the proximity switch is arranged at the lower end of the belt;

the controller receives a proximity signal of the proximity switch to start the hydraulic pump;

the hydraulic pump is connected with the hydraulic cylinder;

the hydraulic cylinder is fixed on the base and provides power for the connecting rod mechanism;

the scraper is a belt cleaning device, and the coal on the belt is loosened by scraping the upper end surface of the belt;

the connecting rod mechanism is a force transmission component between the hydraulic cylinder and the scraper, and applies pressure to the scraper to increase the friction force between the scraper and the belt;

the base is fixedly arranged on the side face of the belt supporting frame.

The connecting rod mechanism comprises a connecting rod, a pull rod and a press rod, the connecting rod is hinged with an extension rod of the hydraulic cylinder, the press rod is hinged at the other end of the connecting rod, the other end of the press rod is hinged with the scraper, and the pull rod is respectively hinged at the middle part of the press rod and the side surface of the hydraulic cylinder.

Detailed Description

The technical solution of the present invention is further described below, but the scope of the claimed invention is not limited to the described.

A coal mine belt cleaning system comprises a proximity switch, a controller and a hydraulic pump, wherein the controller is respectively connected with the proximity switch and the hydraulic pump;

the proximity switch is arranged at the lower end of the belt;

the controller receives a proximity signal of the proximity switch to start the hydraulic pump;

the hydraulic pump is connected with the hydraulic cylinder;

the hydraulic cylinder 4 is fixed on the base 1 and provides power for the connecting rod mechanism;

the scraper 8 is a belt cleaning device, and the coal on the belt is loosened by scraping the upper end face of the belt;

the link mechanism is a force transmission component between the hydraulic cylinder 4 and the scraper 8, and applies pressure to the scraper 8 to increase the friction force between the scraper 8 and the belt 2;

the base 1 is fixedly arranged on the side surface of the belt supporting frame 3.

The connecting rod mechanism comprises a connecting rod 5, a pull rod 6 and a pressure rod 7, wherein the connecting rod 5 is hinged with an extending rod of the hydraulic cylinder 4, the pressure rod 7 is hinged at the other end of the connecting rod 5, the other end of the pressure rod 7 is hinged with a scraper 8, and the pull rod 6 is respectively hinged at the middle part of the pressure rod 7 and the side surface of the hydraulic cylinder 4.

The scraper 8 is triangular, and the tail end of the scraper 8 is provided with a chamfer.

The scraper 8 and the pressure lever 7 are also connected through a tension spring 72.

Two ends of the tension spring 72 are respectively connected to the most adjacent sides of the pressure lever 7 and the scraper 8.

According to the invention, through reciprocating expansion and contraction of the hydraulic cylinder, the connecting rod 5 transmits the thrust of the hydraulic cylinder, the thrust makes the pull rod 5 downwards under the pulling action of the pull rod 6, the pressure rod 7 pushes the scraper 8, and coal attached to the belt is cleaned.
