Description

Technical Field

[0001] The utility model relates to the technical field of material transportation, in particular to a scraper conveyor. Background Art

[0002] A scraper conveyor is a conveyor that uses scraper chains to move bulk materials within a trough. Scraper conveyors are essential for transporting materials in coal mines, chemical mines, metal mines, and power plants. Scraper conveyors offer advantages such as unaffected transport capacity by cargo size and humidity, and a strong, flexible frame. However, since both the material and the scraper chain slide within the trough, scraper conveyors experience significant operating resistance and wear.

[0003] The existing scraper conveyor has a certain downward pressure structure on the chain plate to ensure that the scraper is scraped thoroughly. Under pressure, the scraper and the chute slide and rub against each other, causing serious wear of the chute and high power consumption. If it is not used and maintained properly, accidents such as chain drop, chain floating, chain jamming and even chain breakage may occur. Utility Model Content

[0004] Therefore, the present invention proposes a scraper conveyor to overcome the problems existing in the above prior art.

[0005] The technical solution of the utility model is as follows:

[0006] The transmission mechanism is that the cam is connected with the transmission mechanism, and the transmission mechanism is connected with the transmission mechanism, and the transmission mechanism is connected with the transmission mechanism.

[0007] As a preferred embodiment, the bottom end of the scraper is hinged to the scraper tongue, a torsion spring is provided between the scraper and the scraper tongue, and a limit sill is provided at the hinge between the scraper and the scraper tongue, which limits the angle formed between the scraper and the scraper tongue to less than 100 degrees.

[0008] As a preferred embodiment, the reduction box is a worm gear reduction box, the motor is a three-phase asynchronous motor, and the scraper tongue has a slope tip.

[0009] As a preferred embodiment, each ring of the chain is an O-shaped straight ring, the ring surfaces of two adjacent rings are perpendicular, the ring surface of the chain ring connected to the scraper is located in the vertical plane, and the middle part of the scraper is connected to the chain.

[0010] As a preferred embodiment, the scraper is made of two halves spliced ​​together, with a notch at the splicing point, a chain link fixed in the notch, screw holes are provided at the two halves of the scraper, and the two halves of the scraper are fastened with screws.

[0011] The working principle and beneficial effects of the utility model are as follows:

[0012] The scraper conveyor provided by the utility model is used in which materials are fed into the middle section of the conveyor from a position away from the discharge port. The middle section of the conveyor has an open slot that allows material to be fed from any position. After feeding, the scraper drives the material to the discharge port, completing the conveying process continuously. The scraper conveyor of the utility model has a scraper tongue that can scrape the material more thoroughly, does not require a downward pressure structure on the scraper, does not require high chain tension, and is simple to maintain and is not prone to failure.
