Feeding method and high-efficiency and energy-saving rolling-harrow feeding machine

Abstract

The invention belongs to the field of material conveying, and specifically discloses a feeding method and a high-efficiency and energy-saving rolling-harrow feeding machine, by which fed materials are different in grain size, unequal in grain weight, different in quality, and large and controllable in quantity. The high-efficiency and energy-saving rolling-harrow feeding machine comprises a material guide hopper and a rolling harrow, wherein the rolling harrow comprises a harrow shaft and / or harrow cylinder and the like, the harrow shaft and / or harrow cylinder and the like are arranged on the side part, upper part and / or side upper part of a material, and located between the feed end and discharge end of the material guide hopper or located outside the discharge end of the material guide hopper, and the harrow shaft and / or harrow cylinder are / is arranged perpendicular to the flow direction of the material. By using the method and machine disclosed by the invention, an effect that through setting a material-harrowing bearing and a shaft barrel outside materials, the materials are harrowed from positions beside and / or above the materials, thereby controlling the flow quantity of the materials such as coal and the like; and through real-time adjustment controlling, the purpose of improving efficiency, saving energy, and realizing the optimal feed reshipment is achieved.

Description

technical field [0001] The invention belongs to the field of material conveying, and in particular relates to a method for feeding materials with different sizes, weights, and qualities, and large and controllable feeding amounts, and a rolling rake, environment-friendly, energy-saving and high-efficiency feeder. Background technique [0002] At present, there are currently commonly used feeders, including belt feeders, reciprocating feeders, vibrating feeders, impeller feeders, screw feeders, disc feeders, and scraper feeders. Feeder, etc., the structure and existing problems of the above-mentioned feeder are as follows: [0003] The structure and working state of the belt feeder are as follows: it is mainly composed of a power device, a link device, a ring conveying device, a conveying bucket and a machine base. The endless conveying device consists of driving rollers, reversing rollers, support rollers, and various endless conveyor belts. Ring conveyor belts, armor belt...

AI Technical Summary

Problems solved by technology

The scraper chain of the scraper feeder is easy to get stuck, the bottom plate of the hopper is easy to wear, and the large material is easy to roll on the scraper and skip the scraper, the scraping flexibility is poor, the transmission efficiency is low, the power loss is large, and the position of the whole machine is difficult to adjust , complex structure, many wearing parts, long scraping stroke, less scraping and small feeding volume
