Description

Novel scraper and scraper conveyor thereof

Technical Field

The utility model relates to a conveyer technical field specifically is a novel scraper blade and scraper conveyor thereof.

Background

The double-chain scraper conveyor is mainly used for conveying coal on the coal face of a slowly inclined thin coal layer and an original coal layer under a coal mine, realizes the comprehensive mechanized coal mining of the working procedures of coal dropping, coal loading, coal conveying, pushing, sliding and the like on a stope face, and has the characteristics of strong conveying force, stable transmission, simple structure, convenience in assembly and disassembly, easiness in maintenance, safety, reliability and the like.

The double-chain scraper conveyer is a flexible-traction continuous conveying machine, is a machine arranged for coal conveying of coal mining working faces and mining area roadways, and is characterized in that a traction mechanism is a scraper chain, a bearing device is a loading groove, and the scraper chain is arranged on the groove surface of the loading groove. The loading groove is laid along the whole line of the transportation route, the scraper chain is connected into a closed row by chain wheels of the machine head and the machine tail and is arranged in the loading groove, and when coal loaded into the loading groove is dragged by the scraper chain, the coal slides in the loading groove to the unloading end to be unloaded.

The scraper is generally manufactured by casting, and the traditional structural design, as shown in fig. 3 and 4, results in a heavy scraper, which not only has high cost, but also increases the load of transmission.

SUMMERY OF THE UTILITY MODEL

The to-be-solved technical problem of the utility model is: the scraper blade of solving on the traditional double-stranded scraper conveyor leads to the technical problem that the cost is high, transmission load is big because of the weight is heavier.

The utility model provides a novel scraper blade, which comprises a body, the body both sides are equipped with the loading groove, still be equipped with on the body and subtract heavy groove.

The weight of the body is reduced by the weight reduction grooves, so that the manufacturing cost is reduced, the mechanical performance is improved, the process requirement is ensured, and the transmission load is reduced.

Further, the lightening slot is communicated with the loading slot. So set up, not only simplified the mould structure of casting body, subtract heavy groove in addition and still can be used to load the material to conveying efficiency has been improved.

In order to explain the specific position structure of the weight reduction grooves, in the scheme, the weight reduction grooves are arranged on two sides of the loading groove.

The problem is further improved and solved because the traditional lightening grooves cause uneven mass distribution of the body, so that the body is stressed unevenly and is broken, and particularly, the two sides of the body are provided with bearing parts, and the loading grooves and the lightening grooves are arranged on the bearing parts;

the weight reduction grooves are arranged into a first weight reduction groove and a second weight reduction groove;

the bearing part realizes equal wall thickness under the action of the weight reduction grooves.

Further, the body is made of nodular cast iron. Compared with the traditional steel, the nodular cast iron has the characteristics of low density, high strength, wear resistance and the like.

Further, the surface of the body is thermally treated into HBW370-HBW 450. By the arrangement, the tensile strength of the scraper reaches 1000-1400 MPa, the yield strength reaches 800-1200 MPa, the elongation reaches about 8%, the impact force is stronger, the yield strength and the fatigue strength are excellent, the fracture risk of the scraper can be reduced, and the service life is prolonged.

The utility model also provides a scraper conveyor, ring chain including two symmetrical arrangement, the body is installed on the ring chain. So set up, scraper conveyor life is longer.

Detailed Description

The present invention will now be described in further detail with reference to the accompanying drawings. These drawings are simplified schematic drawings and illustrate the basic structure of the present invention only in a schematic manner, and thus show only the components related to the present invention.

The first embodiment is as follows:

as shown in fig. 1 and 2, the utility model discloses a novel scraper blade, including body 1, body 1 both sides are equipped with symmetrical arrangement's supporting part 3, all are equipped with loading groove 2 on supporting part 3, and loading groove 2 distributes in supporting part 3's bottom surface and side for the transported substance material.

The body 1 is also provided with a weight reduction groove.

The weight of the body 1 is reduced by the weight reduction grooves, so that the manufacturing cost is reduced, the mechanical performance is improved, the process requirement is ensured, and the transmission load is reduced.

Example two:

compared with the first embodiment, the differences are as follows: the lightening slots are also provided on the bearing part 3, communicate with the loading slot 2 and are provided on both sides of the loading slot 2. So set up, not only simplified the mould structure of casting body 1, subtract heavy groove still can be used to load the material moreover to conveying efficiency has been improved.

Example three:

compared with the two examples, the difference is that: the weight reduction grooves are a first weight reduction groove 4 and a second weight reduction groove 5; the first lightening slots 4 are arranged on the outside and the second lightening slots 5 are arranged on the inside. The wall thickness of the support part 3 is equalized by the weight-reduction grooves. The traditional weight reduction groove arrangement can cause uneven mass distribution of the body 1, so that the body 1 is stressed unevenly to cause fracture, and the design solves the problem.

Example four:

compared with the first embodiment, the differences are as follows: the main body 1 is made of nodular cast iron. Compared with the traditional steel, the nodular cast iron has the characteristics of low density, high strength, wear resistance and the like.

Example five:

compared with the fourth embodiment, the differences are as follows: the surface of the body 1 is subjected to heat treatment to form HBW370-HBW 450. By the arrangement, the tensile strength of the scraper reaches 1000-1400 MPa, the yield strength reaches 800-1200 MPa, the elongation reaches about 8%, the impact force is stronger, the yield strength and the fatigue strength are excellent, the fracture risk of the scraper can be reduced, and the service life is prolonged.

Example six:

the utility model also discloses a scraper conveyor, including two symmetrical arrangement's ring chain, five unanimous arbitrary novel scrapers of embodiment are installed on the ring chain. So set up, scraper conveyor life is longer.

In light of the foregoing, it will be apparent to those skilled in the art from this disclosure that various changes and modifications can be made without departing from the spirit and scope of the invention. The technical scope of the present invention is not limited to the content of the specification, and must be determined according to the scope of the claims.
