Abstract
The utility model discloses a scraper blade of a mining conveyor, which comprises a framework, wherein a contact layer is wrapped outside the framework, and the contact layer is specifically made of polyurethane; the framework consists of a supporting part and two assembling parts, the supporting part is provided with a plurality of rows of positioning holes, each row of positioning holes are uniformly distributed along the length direction of the supporting part, and a reinforcing rib is arranged between two adjacent rows of positioning holes; two ends of the supporting part are respectively fixedly connected with the assembling part through a guide plate; the assembly portion all is equipped with two pilot holes. Through skeleton and contact layer cooperation, the contact layer that adopts polyurethane reduces the whole weight of scraper blade, and locating hole and strengthening rib and contact layer cooperation reduce the cracked phenomenon of scraper blade appearance when reducing the whole weight of scraper blade, polyurethane's corrosion resistance extension scraper blade's practical life.
Description
Technical Field
The utility model relates to a scraper blade field especially relates to a mining conveyer scraper blade.
Background
At present, scrapers on a conveying belt of a conveying machine used in coal mine or iron ore mining operation are all made of cast steel or cast iron. The steel scraper conveyor belt has the characteristics that the strength is high, the weight is heavy, the steel scraper conveyor belt is a very traditional equipment part, dozens of steel scrapers with heavy weight are needed for a transmission belt with the length of dozens of meters, and each scraper is arranged on the transmission belt at intervals of one meter and 40 kilograms.
Thus, the steel scraper only greatly increases the transmission power and load of the transmission machine. The replacement of an overweight steel blade with new materials has been a widespread and urgent need.
SUMMERY OF THE UTILITY MODEL
An object of the utility model is to provide a can effectively solve above-mentioned technical problem's a mining conveyer scraper blade.
In order to achieve the purpose of the utility model, the following technical proposal is adopted: a mining conveyor scraper comprises a framework, a scraper body and a scraper blade, wherein a contact layer is wrapped on the outer side of the framework, and the contact layer is specifically made of polyurethane; the framework consists of a supporting part and two assembling parts, the supporting part is provided with a plurality of rows of positioning holes, each row of positioning holes are uniformly distributed along the length direction of the supporting part, and a reinforcing rib is arranged between two adjacent rows of positioning holes; two ends of the supporting part are respectively fixedly connected with the assembling part through a guide plate; the assembly portion all is equipped with two pilot holes.
Preferably, the assembling portion is arranged in parallel with the supporting portion, and an included angle between the guide plate and the supporting portion is 5-10 degrees.
Preferably, the fitting hole is perpendicular to the positioning hole.
Preferably, the contact layer is provided with two U-shaped grooves symmetrically at the two guide plates.
Compared with the prior art, the utility model discloses following beneficial effect has:
through skeleton and contact layer cooperation, the contact layer that adopts polyurethane reduces the whole weight of scraper blade, and locating hole and strengthening rib and contact layer cooperation reduce the cracked phenomenon of scraper blade appearance when reducing the whole weight of scraper blade, polyurethane's corrosion resistance extension scraper blade's life.

Description of the figures
1. Skeleton 2, contact layer 3, supporting part 4, assembly part 5, locating hole 6, strengthening rib 7, deflector 8, pilot hole 9, U type groove.
Detailed Description
The technical solution of the present invention will be clearly and completely described below with reference to the accompanying drawings in the embodiments of the present invention.
As shown in figure 1, the scraper of the mining conveyor comprises a framework 1, wherein a contact layer 2 is wrapped on the outer side of the framework 1. The contact layer 2 is made of polyurethane, and the polyurethane has high hardness, impact resistance, corrosion resistance and light weight.
The framework 1 is composed of a supporting part 3 and two assembling parts 4, and the assembling parts 4 are arranged in parallel with the supporting part 3. The supporting part 3 is provided with two rows of positioning holes 5, and each row of positioning holes 5 are uniformly distributed along the length direction of the supporting part 3.
The locating hole 5 cooperates with the contact layer 2, and when the scraper blade takes place deformation, the locating hole 5 provides 2 deformation spaces of contact layer, improves the toughness of scraper blade.
A reinforcing rib 6 is arranged between the two rows of positioning holes 5, the reinforcing rib 6 improves the overall strength of the scraper and reduces the phenomenon that the scraper is broken.
Two ends of the supporting part 3 are respectively fixedly connected with the assembling part 4 through a guide plate 7, and an included angle between the guide plate 7 and the supporting part 3 is 5-10 degrees. Because the condition of deformation can appear in contact layer 2 in the course of working, the preferred 8 degrees of contained angle between deflector 7 and the supporting part 3, the contained angle of 8 degrees reduces contact layer 2 and takes place the phenomenon of deformation in the forming process, improves the yield of scraper blade, reduction in production cost.
The contact layer 2 is located two U type grooves 9 of equal symmetry of two deflector 7 departments, and the wall thickness in the forming process is controlled in two U type grooves 9, reduces the scraper blade and appears the phenomenon of lacking the material.
Various modifications to these embodiments will be readily apparent to those skilled in the art, and the generic principles defined herein may be applied to other embodiments without departing from the spirit or scope of the invention.
