technical field [0001] The invention belongs to the field of machinery, and in particular relates to a method for rotating and leveling a metering feeder to remove pressure from bins and a dynamic weighing feeder for rotating and leveling to remove bin pressure. Background technique [0002] At present, the field of material storage and transportation is developing rapidly in the direction of automation, intelligence, and remoteness. The material storage and transportation system generally includes three parts: silos, conveying devices and weighing devices. In large-scale large-scale production, the silo needs to be large enough to ensure the required volume. The increase in volume causes a sharp increase in the pressure of the silo.

Problems solved by technology

In large-scale large-scale production, the silo needs to be large enough to ensure the required volume. The increase in volume causes a sharp increase in the pressure of the silo. Automatic and continuous production makes the silo often full, empty, and empty. and other phenomena, the huge silo pressure and frequent changes in the silo cause a huge impact on the conveying device and weighing device, which seriously affects the stability of the conveying device and weighing device, resulting in a large weighing deviation of the weighing device. In order to correct the results, frequent adjustments are required, resulting in uncontinuous production

At present, the feeding device and weighing device use a feeder and a weighing belt conveyor under the silo, and the feeder is added to a weighing belt conveyor. There are large installation space, many equipment, high cost, and difficult adjustment and calibration. , the defect of inaccurate measurement; the current method of dynamic weighing, metering and feeding of belt feeders and A-belt feeders has a compact structure and is easy to automate, but the conveyor belts of belt feeders and A-belt feeders rely on friction The force is driven by the driving drum and the driven drum to feed the material. Because of the large amount of expansion and contraction of the belt and the nail belt, the position of the driving drum and the driven drum often needs to be adjusted to match the tension of the belt and nail belt to continue working. The distance between the rollers at both ends of the belt and the first belt is too far, which not only leads to the breakage of the belt and first belt, causing serious production stoppage accidents, but also often causes overloading of the motor power when the motor starts the belt and first belt rotation due to excessive tension, resulting in motor failure. Burnout and other shutdown failures, and because the belt is attached to the roller and rotates by friction, the two roller shafts are not parallel and the parallelograms appear at the ends of the two roller shafts when the driving roller and the driven roller are installed. In addition, the belt There are no ribs on the edge, there is a gap between the nail belt piercing strip and the perforation, and there are gaps between multiple nail plates, etc., which are affected by tension, temperature, idler rollers, and roller deflection, which will inevitably lead to belt and nail belt running. Frequent running off, resulting in leakage of material, belt, nail belt grinding guide groove, belt, nail belt running deviation, tearing and fracture, etc. Frequent maintenance and replacement on the use site has caused serious waste of manpower and material resources, reducing production efficiency and polluting the environment , the weighing unit of the belt metering feeder and weighing belt conveyor is set at the lower part of the conveyor belt, and the weighing unit weighs the materials on the conveyor belt. This structure has many factors affecting the weighing unit and is random and uncontrollable. Effective correction, resulting in the weighing accuracy can not be improved, the length of the belt type or a belt type metering feeder is short, the tension of the conveyor belt changes greatly, and a stable tension section cannot be formed, and the change of tension affects the weighing accuracy. The large error often overloads the transport plane or the transport vehicle or seriously lacks materials. After the transport vehicle is overloaded, it must find a place to unload the material, and reload the material after the lack of material, which reduces the loading and transportation efficiency and causes a lot of manpower and space. and waste of time, and also caused secondary pollution of the material to the site, air and facilities. In order to solve the above problems, the present invention proposes a method of rotating and leveling the metering feeder to remove the pressure of the warehouse and the method of removing the pressure of the warehouse by rotating and leveling. Dynamic weighing feeder

[0003] But its disadvantage is that the weighing is not accurate

With the increasing popularity of today's mining production for automation, intelligence, and remote control, the application of metering feeders in material conveying systems should be more and more extensive, but due to the weighing accuracy error of metering feeders It is far from meeting the actual needs of modern production with high efficiency, high precision, and high reliability. The main reasons for the inaccurate weighing of the weighing belt conveyor and the current metering feeder are:
