Description

TECHNICAL FIELD

[0001] The present application relates to the field of material weighing and transportation, in particular to a material weighing, transporting and unloading machine. BACKGROUND

[0002] In actual production, it is often necessary to mix raw materials of different weights together, such as the proportioning of animal feed, the production of chemical fertilizer, the proportioning of metallurgical furnace charge, etc., and the precision of the weight of different types of raw materials directly affects the quality of the production product. Therefore, accurate measurement of the weight of raw materials is a prerequisite for high-quality production. The existing technology generally includes the following steps: first, using a weighing sensor to weigh the raw materials, then transferring the raw materials to a transport trolley, and then transporting the materials to the unloading machine position for unloading. The process is complicated and inefficient. If the weighing, transporting and tilting unloading functions can be integrated, the production process can be effectively reduced and the production efficiency can be improved. The technical problem of the existing technology is that conventional weighing sensors cannot simultaneously withstand radial and large axial loads. If the weighing sensor and the transport trolley are integrated together, the weighing sensor will inevitably bear a large lateral load due to inertia when the materials are transported by the trolley after being weighed, and if the material tilting function is also integrated, the tilting process will also cause the weighing sensor to be subjected to an unbalanced load.
