In the process of drive and force application, a fitness effect is achieved, and the swivel chair has the function of preventing too fast rotation.

The invention provides an S-shaped edible mushroom bar conveying vehicle, which comprises a base. Four wheel bearings are welded to the lower end face of the base. The lower end of each wheel bearingis rotationally connected with a wheel through a bearing; a frame plate of an S-shaped structure is fixedly connected to the base. The width of the frame plate is equal to the width of the base, a rotatable handle device is arranged on the plate edge of one side of the base, the rotatable handle device comprises a handle of a U-shaped structure, two rotating grooves are formed in one end of the base, and rotating wheels are rotatably connected to the groove walls of the two sides of each rotating groove through pin shafts. The mushroom bar barrel bags are conveyed through the frame plate of the S-shaped structure, due to the fact that the concave shape of the frame plate is matched with the mushroom bar barrel bags, the wrapping performance of the bags is improved, the situation that the bags fall off in the transportation process is reduced, the survival rate of mushroom bars is increased, meanwhile, the single-time conveying number can be increased through the frame plate, and the conveying efficiency is improved.

The invention discloses an oil removing and slag skimming device for a sewage treatment plant. The device comprises a sewage tank; a first screw rod is arranged in the sewage tank; two moving plates sleeve the first screw rod in a threaded manner; internal threads with opposite directions are respectively arranged in the two moving plates; two ends of each moving plate are abutted against inner side walls of the sewage tank; a damping device is fixed at the bottom end of one moving plate; a moving device is arranged between the damping device and the inner bottom end of the sewage tank; a conveying belt is arranged between the two moving plates; scrapers are arranged on the conveying belt; a second rotating shaft is fixedly sleeved by one side, far away from the first screw rod, of the conveying belt; and the second rotating shaft is rotationally provided with an object table.
