The lower ends of the two baffle plates 403 are installed on the other two sides above the discharge port 4010. The upper ends of the two baffle plates 403 are respectively blocked at the upper position of the lower end of the stirring tank 1.
[0017] The support platform 401 includes four supports and a rectangular platform. A support is installed at each of the four corners of the lower end of the rectangular platform. The stirring mechanism 20 is installed on the rectangular platform. A discharge port 4010 is opened on the rectangular platform. The discharge port 4010 is located below the stirring tank 1 of the stirring mechanism 20.
[0018] The lower opening of the lower hopper 402 is designed with an outward horizontal fold 4020 on either side. The upper opening of the receiving hopper 301 is designed with an inward horizontal fold 3010 on either side, with a notch on one side. The two outward horizontal folds 4020 of the lower hopper 402 are inserted through the notch below the two inward horizontal folds 3010 of the receiving hopper 301. The other two sides of the lower opening of the lower hopper can also be designed with outward horizontal folds, and the other side of the receiving hopper opening corresponding to the notch can also be designed with an inward horizontal fold. The outward horizontal fold is located above the inward horizontal fold, which can effectively provide a sealing effect.
[0019] The mixing tank 1 is designed with a discharge port at the lower end, and the discharge port is sealed by a discharge cover 2 below. The discharge cover 2 is rotatably installed at the discharge port position, and the discharge cover 2 is driven to rotate by a hydraulic cylinder assembly; the hydraulic cylinder assembly includes a rotating shaft 3, a pull rod 4, and a hydraulic cylinder 5. The two ends of the cylinder body 1 are respectively installed on the support platform 401 through side plates 6. The cylinder body 1 is designed with a discharge port at the lower end, and the outer side of the discharge port is covered with a discharge cover 2. The lower end of the discharge cover 2 is fixedly connected to one side of the rotating shaft 3 through a connecting piece 8. The two ends of the rotating shaft 3 are rotatably installed on the side plates 6 at both ends. One end or both ends of the rotating shaft 3 pass through the side plates 6 on the corresponding side and are fixedly connected to the upper end of the pull rod 4. The lower end of the pull rod 4 is rotatably connected to the telescopic end of the hydraulic cylinder 5, and the lower end of the hydraulic cylinder 5 is installed on the support platform 401. The connecting member 8 includes a horizontal plate 81, a vertical plate 82, and a fixed sleeve 83. The horizontal plate 81 is fixed under the discharge cover 2, and a vertical plate 82 is vertically installed on the horizontal plate 81.

The upper edge of the triangular plate is fixedly connected to the horizontal plate 81, and the raised corner of the lower end of the triangular plate is reserved with a connection hole. The triangular plate design and the reserved connection hole are to prevent the hydraulic cylinders on both sides from failing to work, so that a spare hydraulic cylinder can be connected in an emergency. The upper telescopic end of the hydraulic cylinder is connected to the connection hole, and the lower end of the hydraulic cylinder is rotated and fixed on the support platform. The discharge cover is designed as a contoured cover plate with the same upper end surface as the bottom of the cylinder body. The contoured cover plate just matches the structure of the bottom of the cylinder body, which can not only close the discharge port but also does not affect the stirring work of the stirring paddle assembly in the cylinder body.
[0020] When the utility model is in use, the hydraulic cylinder assembly controls the discharge cover below the mixing cylinder to flip, and the semi-dry material falls from the discharge port. The generated dust and odor are all sealed by the side plates and two baffle plates on both sides. The semi-dry material continues to fall from the discharge port along the discharge hopper into the receiving hopper of the extrusion mechanism, and then enters the extrusion mechanism. The extrusion mechanism further kneads, extrudes, cuts, and performs other operations through the spiral extrusion mechanism. The entire discharge process realizes a fully enclosed material transfer. By installing the stirring mechanism above the extrusion mechanism, the discharge and receiving materials are sealed and connected, which makes discharge convenient and shortens the transfer time. It also solves the problems of flying dust and overflowing irritating odors, reduces the labor intensity of workers, and improves the safety factor of the workers' operating environment. The stirring mechanism and the extrusion mechanism are both existing technologies. The utility model is briefly described. The utility model adopts an upper and lower structure. Through the closed material transfer mechanism, it realizes rapid material transfer, no dust, no odor, and is safe and reliable.
