This utility model discloses a ceramic barbecue grill fume treatment structure, including a ceramic barbecue grill body. A top cover is rotatably connected to the top of the ceramic barbecue grill body, and a filter box is fixedly connected to the top of the top cover. A filter assembly is installed on the top of the filter box. This utility model utilizes an exhaust fan to draw air upwards, extracting air from the interior of the ceramic barbecue grill body. The fume enters the filter box through a collection hood, where it passes through a filter plate to filter impurities and fumes, effectively removing grease and odors. The fume is then discharged through the exhaust fan. The rotation of the exhaust fan drives a sleeve to rotate, which in turn drives a cleaning rod, causing a cleaning brush to rotate and clean the dirt on the filter plate, preventing grease buildup and ensuring proper fume discharge. This replaces existing methods that do not treat the fume, thus providing thorough fume treatment and filtration.

This utility model discloses a mulching device for soil remediation, including a base frame and a side-cushioning and lifting frame. The side-cushioning and lifting frame is fixedly installed on one end of the base frame. A winding frame is installed on the top side of the side of the side-cushioning and lifting frame. A mulching winding roller is rotatably installed on the winding frame via a winding shaft. The side-cushioning and lifting frame is provided with a pressing and adjusting groove. An adjusting slider is slidably installed in the pressing and adjusting groove. An upper pressing cylinder is rotatably installed on the adjusting slider via an upper pressing cylinder shaft. A lower pressing cylinder is rotatably installed on the side-cushioning and lifting frame below the upper pressing cylinder via a lower pressing cylinder shaft. A compression spring is connected and installed between the adjusting slider and the upper wall of the pressing and adjusting groove. The beneficial effects of this utility model are: the two ends of the mulch are more stable during the remediation process, and the whole device is easy to move after winding, without the need for a lifting structure to drive the winding and lifting.
