The utility model belongs to the technical field of cleaning equipment, and particularly relates to an edible oil filling barrel cleaning device which comprises a handle rod, a center frame is fixedly connected to the upper end of the handle rod, side frames are installed on the two sides of the center frame through interval adjusting mechanisms, and cleaning strips are fixedly connected to the sides, away from each other, of the two side frames. The distance adjusting mechanism comprises a return spring installed between the side frame and the center frame, a pressure spring piece located between the center frame and the side frame is installed on the center frame through a position adjusting piece, the two ends of the return spring are fixedly connected with the side frame and the pressure spring piece respectively, and the position adjusting piece is a screw connected to the center frame in a threaded mode. One end of the screw is rotationally connected with the pressure spring piece, sliding strips are slidably connected to the two sides of the center frame, and the ends of the sliding strips are fixedly connected with the side frames. The cleaning device can reduce the cleaning difficulty, improve the cleaning effect and reduce the difficulty when the cleaning device goes in and out of filling barrels with different inner diameters.

This utility model discloses an anti-clogging adaptive threshing structure for a sunflower harvester, comprising a transmission chamber. Inside the transmission chamber, several transmission rollers are evenly and movably arranged via a rotating shaft. Several levers are evenly and fixedly arranged on the surface of each transmission roller. An adaptive anti-clogging adjustment mechanism is located at the lower end of each transmission roller inside the transmission chamber. The adjustment mechanism includes a rotating shaft, a separating screen, a first fixed block, a second fixed block, and a damping cylinder. The rotating shaft is movably arranged on one side of the transmission chamber via a bearing, and the separating screen is fixedly arranged on the outer side of the rotating shaft. This utility model offers good performance. The separating screen can be connected via a rotating shaft and a spring, allowing the damping cylinder to compress and the separating screen to rotate when a large number of sunflower trays are fed into the machine at once. This increases the distance between the transmission rollers and the separating screen, thus preventing clogging.

The utility model provides an automatic temperature control device for a rubber raw material drying chamber, which solves the technical problems of high steam consumption, unbalanced temperature in the drying chamber and influence on the rubber heating quality in the existing rubber drying mode, and can be widely applied to the field of rubber temperature control. The device specifically comprises a box body, a heating plate, an exhaust fan, a motor, a temperature sensor, a timer, a motor fixing frame, a controller, a button, a power supply and an adsorption mechanism, the box body is of a hexagonal hollow structure, irregular hexagonal openings are formed in the front portion and the rear portion of the box body, and rectangular openings are formed in the upper side face, the left side face and the right side face of the box body. The heating plates are of a latticed structure and are arranged in openings in the front, rear, upper, left and right lower side surfaces of the box body; an electric heating wire is wound on a frame of the heating plate, and the heating plate is used for heating the interior of the drying chamber; three screw holes are formed in each of the upper end and the lower end of the opening in the left and right upper side surfaces of the box body.
