Technical Field

[0001] The utility model belongs to the technical field of scraper machines, and more specifically, particularly relates to a scraper machine material gate residue cleaning structure. Background Art

[0002] A material gate is usually installed at the head or tail of a scraper conveyor to control the flow of materials to avoid excessive or insufficient material transportation. It can also prevent backflow or overflow of materials when the scraper conveyor starts or stops. Most of the existing material gates use cylinder action to drive the gate plate to swing to achieve control of the opening and closing of the gate. After the material gate has been used for a period of time, a lot of materials will adhere to the gate plate or the inner wall of the gate. These materials are prone to mold if not cleaned for a long time, and are easy to fall into fresh materials when the scraper conveyor is running, affecting the use effect of the scraper conveyor. Therefore, the material gate needs to be cleaned and maintained regularly after a period of use.

[0003] For example, CN210504317U discloses a scraper gate that is not prone to material accumulation, which relates to the field of gate technology and aims to solve the technical problem that when the gate is opened, the gate plate is lifted upward, causing the material on the gate plate to fall along the gate to between the gate and the gate plate, and the material will become moldy if it is not cleaned for a long time. The key points of its technical solution are that a discharge assembly is arranged in the shell, and the discharge assembly includes a baffle plate, an intermediate nylon plate, a gate plate and a connecting plate, the baffle plate is fixedly connected to the intermediate nylon plate, and the connecting plate is connected to the inner wall of the shell; a gate plate seat is arranged on the lower surface of the gate plate, the intermediate nylon plate is located between the two gate plate seats, and a limiting hole is arranged on a side of the gate plate seat close to the intermediate nylon plate; a first sliding groove is arranged on the lower surface of the intermediate nylon plate along its height direction, a rocker is arranged in the first sliding groove, and the rocker is located in the limiting hole; a driving assembly is arranged on the side wall of the shell, and the driving assembly is connected to the rocker; the effect of not being prone to material accumulation is achieved.
