[0002] A sintering machine is a device that sintered mixed ore. The mixed material moved forward on a trolley and burned after passing through an igniter.

[0023] Principle of use: When in use, the trolley moves forward continuously, passing through the distributor, this device and the igniter in turn. The trolley receives the mixed material through the distributor, is scraped flat when passing through this device, and is ignited by the igniter. The surface of the material on the trolley is uneven. When the surface of the mixed material passes through the scraper 4, the higher surface material is scraped and blocked in place by the scraper 4. This part of the blocked accumulated material is continuously used to fill the passing pits; in this process, when the material pile only triggers the signal corresponding to the bottom plate 5, if the bottom touch pressure switches corresponding to all the bottom plates 5 are triggered, it means that the thickness of the accumulated material is normal at this time, and the subsequent pits can be continuously filled; such as If there is no signal from individual bottom plates, it means that there is no accumulated material in front of this bottom plate and the pits cannot be filled, then the first motor and the second motor are started to drive the dividing plate 13 to move to the bottom plate next to the bottom plate without signal, and then the dividing plate 13 will distribute the accumulated material in front of the bottom plate with signal to the front of the bottom plate without signal, ensuring that there is accumulated material in front of the bottom plate to fill the pits on the surface of the mixed material layer; after the material is divided by the dividing plate 13, if there are still individual bottom plates without trigger signals, the hydraulic cylinder drives the scraper to move down appropriately until all the bottom plates trigger the signal normally; when the material pile triggers the top touch pressure switch corresponding to the top plate, the hydraulic cylinder is started to lift the scraper to avoid excessive accumulation of material affecting the distribution of materials.
