Description

Technical Field

[0001] This utility model relates to the field of scraper conveyors, specifically to a lightweight cast stone trough scraper conveyor scraper. Background Technology

[0002] Scraper conveyors are commonly used bulk material conveying equipment in industries such as coal mining, metallurgy, and chemicals. The performance of their core component, the scraper, directly affects conveying efficiency and equipment lifespan. Traditional scraper designs often suffer from the following problems: First, the scraper's bending resistance is insufficient, making it prone to deformation or even breakage when subjected to material impact and friction, leading to equipment downtime and reduced production efficiency. Second, the reliability and service life of the scraper are limited. They typically employ an integral structure, meaning that once the working surface wears down, the entire scraper needs to be scrapped, resulting in resource waste and increased maintenance costs. Third, for small scraper conveyors, existing scraper designs cannot fully meet their space requirements.

[0003] Therefore, there is an urgent need for a lightweight scraper for cast stone trough scrapers to solve the problems of poor bending resistance, low reliability, short service life and resource waste of existing scrapers. It is especially suitable for small scraper machines. Through innovative structural design, it can significantly improve the overall performance of the scraper, achieve energy saving and environmental protection, and has a simple and reliable structure, is easy to operate, has low maintenance cost and wide applicability. Utility Model Content

[0004] A lightweight scraper for a cast stone trough scraper machine is designed to solve the problems of poor bending resistance, low reliability, short service life, and resource waste of existing scrapers. It is particularly suitable for small scraper machines. Through innovative structural design, the comprehensive performance of the scraper is significantly improved, achieving energy saving and environmental protection. Its structure is simple and reliable, easy to operate, low in maintenance cost, and widely applicable.

[0005] This utility model provides a lightweight scraper for a cast stone trough scraper machine, characterized in that it includes a reinforcing steel plate, a main steel plate disposed on the upper part of the reinforcing steel plate, and a spare steel plate disposed on the lower part of the reinforcing steel plate, wherein: The reinforcing steel plate is symmetrically provided with connecting earrings at both ends; The reinforcing steel plate is symmetrically provided with a set of snap-fit ​​devices on its upper and lower sides; A set of connecting protrusions is symmetrically provided on both sides of the main steel plate and the spare steel plate, and the set of connecting protrusions is respectively opened on both sides of the main steel plate and the spare steel plate; The main steel plate and the spare steel plate are snapped together with the reinforcing steel plate, and the reinforcing steel plate is arranged on the back of the main steel plate along the length direction of the main steel plate.

[0006] Preferably, the connecting protrusions on the main steel plate and the spare steel plate are all located at the middle position on both sides of the main steel plate and the spare steel plate.

[0007] Preferably, the reinforcing steel plate is a long, straight strip, and the snap-fit ​​device and connecting protrusion are detachably connected. The top of the snap-fit ​​sidewall is provided with a snap-fit ​​limiting block to form a snap-fit ​​groove.

[0008] Preferably, the snap-fit ​​device includes a snap-fit ​​sidewall, and a snap-fit ​​limiting block is provided at the top of the snap-fit ​​sidewall.

[0009] Preferably, the snap-fit ​​sidewall is provided with mounting holes on both sides, and the connecting protrusions on both sides of the main steel plate and the spare steel plate are provided with connecting holes. The mounting holes and connecting holes are connected and locked by bolts and anti-loosening nuts.

[0010] Preferably, both the main steel plate and the spare steel plate have working surfaces on both sides, with symmetrical structures and flat surfaces.

[0011] Preferably, the connecting earring is circular, with its central axis perpendicular to the length direction of the main steel plate.

[0012] Preferably, the reinforcing steel plate is made of low-alloy high-strength structural steel, and the main steel plate and the spare steel plate are made of mining steel.

[0013] The beneficial effects of this invention are as follows: This device provides additional support and rigidity to the scraper by introducing a reinforcing steel plate and placing it on the back of the main steel plate. The reinforcing steel plate is made of low-alloy high-strength structural steel, whose excellent mechanical properties effectively enhance the overall bending resistance of the scraper, making it less prone to deformation under high-intensity impacts and heavy loads, thus significantly reducing the risk of scraper damage. This design introduces replaceable main steel plate and spare steel plate. When the working surface wears, only the worn steel plate needs to be replaced, without scrapping the entire scraper, greatly extending the overall service life of the scraper. The main steel plate and spare steel plate are detachably connected to the reinforcing steel plate through a snap-fit ​​device, making replacement simple and quick, reducing maintenance time and costs. Both sides of the main steel plate and spare steel plate are working surfaces, and the two sides are symmetrical and flat. This means that when one side wears, the steel plate can be flipped over to use the other side, further extending the service life of individual components and achieving full utilization of resources. This design significantly reduces the number of discarded scrapers, reduces material requirements, and saves operating costs. Its lightweight design and modular structure allow it to adapt well to the characteristics and needs of small scraper conveyors. While ensuring performance, it also takes into account the overall size and weight of the equipment, thus improving the applicability and economy of small scraper conveyors.
