A coal seam gas sampling device, comprising: a gas extraction pipe for extracting gas, the gas extraction pipe is provided with a gas outlet pipe on the side wall; an air inlet head detachably connected to the bottom of the gas extraction pipe; a joint mechanism slidably connected to the side wall of the air inlet head; a gas extraction mechanism slidably connected to the inner wall of the gas extraction pipe; an auxiliary mechanism provided at the bottom of the gas extraction mechanism, the auxiliary mechanism comprising a suction fan; and a gas collection bag detachably connected to the gas outlet pipe. When sampling, the air inlet head is pushed downward, so that the valve ball moves upward, thereby forming a gap between the valve ball and the opening, at this time the collected gas can enter the gas extraction pipe through the gap. When the sampling is completed, the gas extraction pipe is pulled upward, so that the conical pipe also moves upward, at this time the valve rod is separated from the opening, and the valve ball is re-sealed due to gravity. The output end of the motor is fixedly connected with the suction fan, and the motor drives the suction fan to rotate after starting, thereby accelerating the speed of the airflow and improving the speed of gas collection.

The application discloses a kind of poultry processing production line, it is related to poultry processing technical field, the present application, including: frame, frame is provided with connecting plate one, connecting plate one is provided with conveying equipment, the top of connecting plate one is fixedly connected with electric slide rail, the moving end of electric slide rail is fixedly connected with mobile T plate, the top of mobile T plate is fixedly connected with fixed frame one, the below of fixed frame one is provided with push mechanism, the inner wall of conveying equipment is provided with cleaning mechanism, the present application makes nozzle by water pipe and water pump in storage tank liquid is sprayed to the surface of goose, can carry out clean water cleaning to the surface of goose, after washing, enter scalding pool, can reduce the pollution to scalding pool, can improve the production quality of subsequent goose, reduce pollution, improve the goose processing production efficiency of the device, can make the clean water that nozzle sprays clean the root of goose feather, turn up the root of goose feather outward, expose goose feather root and skin.

This utility model discloses a device for recycling zinc casting slag, including a waste liquid tank. A mounting frame is fixedly connected to the side wall of the waste liquid tank. A machine frame is fixedly connected to the side of the mounting frame away from the side wall of the waste liquid tank. A liquid delivery pipe is fixedly connected to the side wall of the machine frame. A water pump is provided on the side of the liquid delivery pipe away from the machine frame. A liquid guide pipe is provided at the end of the water pump away from the liquid delivery pipe. A separation mechanism is provided inside the machine frame. The water pump draws water in the waste liquid tank, causing it to move in the direction of high flow velocity under pressure. At this time, the floating compounds in the water can follow and flow into the interior of the machine frame. The separation mechanism then cleans the floating compounds to the surface of a rotating plate, which rotates to collect and process them, thus accelerating the collection speed. This improves work efficiency and cleans the floating compounds in the water more thoroughly, thereby improving the purity of zinc.
