Problems solved by technology

[0003] However, scraper conveyors are usually used in coal mines and other environments with poor environmental cleanliness. There are usually impurities such as coal powder and sludge on the material conveying trough. During the operation of the scraper, impurities are easy to enter the casing.
After a long time of use, the impurities accumulated in the casing will increase the rolling resistance of the balls, and even cause the balls to be stuck in the casing and be difficult to rotate, affecting the normal use of the device

Abstract

The invention relates to the technical field of material conveying devices, in particular to a scraper conveyor, a scraper and a rolling body. The scraper conveyor comprises a material conveying groove, an annular chain, a scraper body, the rolling body and a spraying device. The annular chain can circularly move relative to the material conveying groove; the scraper body is installed on the annular chain, a fixing hole and a sewage draining hole which communicate with each other are formed in the scraper body, and the fixing hole and the sewage draining hole penetrate through the scraper body; the rolling body is mounted in the fixing hole and comprises a shell and a ball, a mounting cavity is formed in the shell, the ball is mounted in the mounting cavity and partially extends out of the bottom side of the shell, and the shell is provided with a sewage outlet hole communicating with the mounting cavity and the sewage draining hole; and the spraying device is arranged on the machine head and / or the machine tail, and when the scraper body is turned over at the machine head or the machine tail, the spraying device can spray towards the sewage draining hole of the scraper body. The scraper body and the rolling body can be cleaned through water flow, the situation that the ball is clamped in the mounting cavity is reduced, and the rolling performance of the ball is improved.

Description

technical field [0001] The invention relates to the technical field of material conveying devices, in particular to a scraper conveyor, a scraper, and a rolling body. Background technique [0002] A scraper conveyor is a conveying device for transporting coal and materials, usually including an endless chain and a scraper mounted on the endless chain, the endless chain can drive the scraper to move on the material conveying trough of the scraper conveyor. In order to reduce the friction loss between the scraper and the material conveying trough, there is a rolling element at the bottom of the existing scraper. The rolling element includes a shell and balls that can roll in the shell. Some of the balls protrude from the bottom side of the shell, so that they can Rolling on the material conveying trough to change the sliding friction between the scraper and the material conveying trough into rolling friction, thereby reducing the running resistance of the scraper and reducing ...
