CN-224225918-U - Multi-field wear-resistant scraper machine

Abstract

The application discloses a multi-field wear-resistant scraper machine, which mainly solves the technical problem that the bottom of a groove body of the existing scraper machine is easily worn in the transportation process to influence transportation. The automatic feeding machine comprises a middle part provided with a middle groove, a machine head and a machine tail which are correspondingly connected to two ends of the middle part, wherein the middle groove comprises a groove body, limiting plates which are symmetrically buckled at the tops of two sides of the groove body and correspondingly form limiting cavities with groove walls of two sides of the groove body, a plurality of supporting rollers which are arranged between the groove body at equal intervals in the axial direction perpendicular to the groove body, chains which circularly run on the upper side and the lower side of the supporting rollers along the axis of the groove body, chain plates which are fixed at the positions of the chains at equal intervals and are perpendicular to the axis of the groove body, and belts which are connected between the adjacent chain plates and are in sliding contact with the supporting rollers, wherein limiting parts which correspondingly extend into the limiting cavities are arranged on two sides of the chain plates. The scraper can avoid direct contact of the bottom of the material tank body, thereby ensuring the relative integrity of the tank body.

Description

Multi-field wear-resistant scraper machine Technical Field The application relates to the technical field of scraper machines, in particular to a multi-field wear-resistant scraper machine. Background A scraper conveyor is a continuous conveyor that conveys bulk material by means of a moving scraper chain. The device is widely applied to various industries such as coal, metallurgy, building materials, chemical industry, electric power and the like, and is one of main coal transportation equipment especially in underground coal mining working surfaces of coal mines. The scraper mainly comprises a machine head, a middle part, a machine tail part and other parts, and is also provided with a hydraulic jack device for pushing the conveyor and accessory parts such as a chain tightening device for tightening the chain. The scraper chain is driven by the machine head and the machine tail chain wheel to do circular motion along the groove body of the conveyor, and then the scraper on the scraper chain scrapes the materials from the feed inlet to the discharge outlet, so that continuous conveying of the materials is realized. In the process of transporting materials in the use scenes of various fields, the scraper machine inevitably has abrasion problems due to the influences of various factors such as material characteristics, running environments and the like. These wear problems not only affect the service life and the operating efficiency of the scraper but also may cause equipment malfunctions and safety accidents. Specifically, as the groove body is a main channel for conveying materials by the scraper, the materials can generate friction and impact on the bottom and the side wall of the groove body when moving in the groove body, especially under the use conditions of large material flow and high particle hardness, the abrasion of the bottom area of the groove body is most obvious, so that the leakage of the materials can be caused, the conveying efficiency is reduced, and even the safety accidents such as cracking of the groove body can be caused. The information disclosed in this background section is only for enhancement of understanding of the background of the disclosure and should not be taken as an acknowledgement or any form of suggestion that this information forms the prior art that is well known to a person skilled in the art. Disclosure of Invention In view of at least one of the above technical problems, the present disclosure provides a multi-field wear-resistant scraper machine, which mainly solves the technical problem that the bottom of a tank body of an existing scraper machine is easily worn in the transportation process to affect transportation.
