Description

Technical Field

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

[0002] The buried scraper conveyor is a kind of bulk material continuous conveying equipment with strong versatility and outstanding features. It can be widely used in machinery, metallurgy, chemical industry, grain, hydropower, ports, medicine, transportation, health, environmental protection and other fields. It can convey various dusty, small particles and small block materials, and can convey them horizontally, inclined or vertically.

[0003] Vertical buried scraper conveyors are generally used to transport general materials with good performance or small particle size. However, nowadays, vertical buried scraper conveyors are often used to transport materials with strong abrasiveness, high specific gravity and large particle size. When transporting these materials, the following problems often occur:

[0004] When materials are conveyed on the inclined section, they often slide down from the gap between the scraper and the shell, thereby reducing the lateral pressure between the materials and the internal friction between the materials. As a result, the materials cannot form a stable material flow inside the inclined section shell, resulting in a decrease in the conveying capacity. In severe cases, it may cause blockage in the curved section, which may lead to equipment shutdown or scraper chain breakage and other equipment failures. Utility Model Content

[0005] The purpose of the utility model is to solve the shortcomings of the prior art that the material slides downward from the gap between the scraper and the shell, thereby reducing the lateral side pressure between the materials, reducing the internal friction between the materials, and making it impossible for the material to form a stable material flow inside the inclined section shell, and to propose a vertical buried scraper conveyor.

[0022] Next, the technical solutions in the embodiments of the present utility model will be clearly and completely described in conjunction with the accompanying drawings in the embodiments of the present utility model. Obviously, the described embodiments are only a part of the embodiments of the present utility model, rather than all the embodiments.

[0024] The scraper chain 4 includes a plurality of link rods 41, and the plurality of link rods 41 are connected by pin shafts 44. A retaining ring 45 is connected to the bottom end of each pin shaft 44. Scrapers 42 are fixedly connected to both sides of each link rod 41, and side baffles 43 are fixedly connected to each scraper 42.

[0025] Working process:

[0026] The stall alarm mechanism 9 is installed on the tail shaft at the tail and rotates synchronously with the tail shaft. When the conveyor is overloaded, jammed or has other faults, resulting in the tail shaft speed exceeding the set value, a signal is output to the electrical control system, and the protector will actuate an alarm and stop the machine to ensure the safety of the conveyor. At the same time, side baffles 43 are added to the scrapers of the chain, which can effectively prevent the material from sliding down through the gap between the scraper and the housing, thereby ensuring the lateral side pressure and internal friction force between the materials, forming a stable material flow inside the inclined section housing, and ensuring the material conveying capacity.
