An online weighing bucket device for a ship unloader

Abstract

The invention relates to a weighing bucket device of a ship unloader, in particular to an online weighing bucket device of a ship unloader. The device includes a ship unloading frame, a grab bucket, a metering bucket, a metering device, and a hopper. The metering hopper is set above the hopper and has a bucket door. The scale is supported under the measuring hopper, the auxiliary scale and the measuring hopper are not in contact and are provided with standard weights, and the main scale and the auxiliary scale are fixed side by side on the bottom plate. The device can also be additionally equipped with a labyrinth body, a hydraulic damper, a measuring bucket anti-side swing device, a controller, and a central controller. The invention can use the ship unloader itself to weigh the material, improves the measurement accuracy and work efficiency, saves the cost of the enterprise, and realizes effective management.

Description

technical field [0001] The invention relates to a weighing bucket device of a ship unloader, in particular to an online weighing bucket device of a ship unloader. Background technique [0002] In the existing port operation process, the electronic belt scale is generally used to measure the goods. The electronic belt scale belongs to continuous dynamic measurement. Although with the development of technology, the theoretical measurement accuracy of the electronic belt scale can reach 0.5%, but in In the actual work of the wharf, due to the influence of the use environment, wind force, material characteristics, weather and temperature changes, the 0 point drift of the electronic belt scale after calibration is relatively large, and the actual measurement accuracy is much greater than 0.5%, which is greatly different from the theoretical accuracy. Therefore, the electronic belt scale can only be used as an internal management measurement, and neither the buyer nor the seller c...

AI Technical Summary

Problems solved by technology

Although this method uses the ship unloader's own mechanism and device instead of the electronic belt scale to measure the material, the accuracy has also been improved, but there are many disadvantages that lead to the failure of such attempts: first, the ship unloader There is vibration in the operation project, and the error of material weighing is very large. Therefore, every time the receiving hopper is finished receiving the material and the material is put into the weighing hopper, the ship unloader needs to stop the operation and wait for the vibration to stop, then weigh the material, and wait for the weighing to be completed. Only after the grab can start to grab the material again and carry out the operation of the next cycle, which greatly reduces the unloading efficiency of the ship unloader

Second, because the ordinary ship unloader has only one layer of buckets, after adding two layers, the height of the ship unloader has increased a lot, which greatly increases the lifting height of the grab bucket for retrieving materials, and the cycle of retrieving materials becomes longer, and then wait for the end of the measurement Finally, the time is longer, so that when the discharge hopper discharges the material to the belt conveyor, the material for the next time has not been released after the previous discharge is completed, resulting in discontinuous sections of material on the belt conveyor, and there is no material to send. The production efficiency of the port has been reduced, and because the lifting height of the grab has increased a lot, the energy consumption of the enterprise has increased significantly

Moreover, the whole system is too complicated, there are many equipment failure points, and the workload of maintenance is quite large.
