AI Technical Summary
Coal material is prone to adhere to the inner wall during the feeding process of grabbing, resulting in a decrease in the amount of single grabbing and difficulty in cleaning after long-term use.
A heater plate with an equally distributed distribution is set on the inner wall of the grab to dry the coal material and improve fluidity; at the same time, a motor-driven scraper system is designed for cleaning the inner wall of the grab.
Through the drying of the heating plate, the adhesion of coal material is reduced and the amount of loading is increased for a single time; the use of the scraper system effectively avoids coal material accumulation and simplifies the cleaning process.

Description
Technical Field
[0001] The utility model relates to the technical field of transportation, in particular to a raw material transportation device. Background Art
[0002] Grab bucket plays an important role in the process of loading coal raw materials.
[0003] The grab can load large amounts of coal from the storage area or yard and transport it to the target location quickly and efficiently through its large capacity and strength. The grab can be precisely controlled and adjusted as needed. By controlling the opening and closing degree and lifting speed of the grab, the operator can adjust the loading speed and capacity according to actual conditions. This enables flexible response to process changes and demand fluctuations to meet specific production requirements.
[0004] However, when the coal is wet, part of the coal will adhere to the inner wall of the grab when the grab is loading the coal. The accumulation of coal on the inner wall reduces the amount of coal grabbed at a time, and long-term use of squeezing makes it difficult to clean the accumulated coal. For this reason, we propose a raw material transportation device to solve the existing problem. Utility Model Content
