[0013] Refer to the attached Figure 1-4The locking mechanism 101 of the discharging cover of the kneading machine comprises a cylinder body 1, a discharging port is designed at the lower end of the cylinder body 1, and the discharging port is blocked by the discharging cover 2, and the discharging cover 2 is rotatably mounted at the discharging port position, and the discharging cover 2 is driven to rotate by the hydraulic cylinder assembly and the discharging cover is locked by the locking mechanism. The locking mechanism 10 comprises a locking cylinder 101, a U-shaped clamping plate 102, an upper clamping plate 103, and a lower clamping plate 104. The upper clamping plate 103 is mounted on the outside of the discharging port, and the lower clamping plate 104 is mounted on one end of the discharging cover 2, and in the closed state of the discharging cover 2, the lower clamping plate 104 is located directly below the upper clamping plate 103. The locking cylinder 101 is mounted on one side of the lower end of the cylinder body 1, and the telescopic end of the front end of the locking cylinder 101 is mounted with a U-shaped clamping plate 102. The locking cylinder 101 controls the U-shaped clamping plate 102 to be stuck above the upper clamping plate 103 and below the lower clamping plate 104. After the U-shaped pallet clamps the upper and lower pallets, the hydraulic cylinder assembly does not need to be continuously supplied with oil, and the hydraulic system does not need to work, which reduces energy consumption and reduces the leakage problem of the hydraulic system.
[0014] The inner walls of the two side panels of the U-shaped card plate 102 are designed to be inner inclined surfaces 1020, and the inner inclined surfaces 1020 on both sides form a trumpet shape; the upper end surface of the upper card plate 103 is designed to be an outer inclined surface 1030, and the lower end surface of the lower card plate 104 is designed to be an outer inclined surface 1030. The outer inclined surfaces 1030 of the upper card plate 103 and the outer inclined surfaces 1030 of the lower card plate 104 form an "eight" shape. The two inner inclined surfaces 1020 of the U-shaped card plate 102 are respectively cut and pressed on the upper and lower outer inclined surfaces 1030 of the upper card plate 103 and the lower outer inclined surfaces 1030 of the lower card plate 104. The outer surface design structure of the upper and lower card plates and the inner surface design structure of the U-shaped card plate form an inclined extrusion structure. The locking cylinder pushes the U-shaped card plate forward, and the U-shaped card plate can tightly squeeze the upper and lower card plates inward, ensuring that the flip cover plate and the discharge port are tightly matched and the sealing effect is good.
[0015] The hydraulic cylinder assembly includes a rotating shaft 3, a tie rod 4, and a hydraulic cylinder 5. The two ends of the cylinder body 1 are mounted on a base 7 via side panels 6. A discharge port is provided at the lower end of the cylinder body 1, covered by a discharge cover 2. The lower end of the discharge cover 2 is fixedly connected to one side of the rotating shaft 3 via a connector 8. The two ends of the rotating shaft 3 are rotatably mounted on the side panels 6 at either end. One or both ends of the rotating shaft 3 pass through the corresponding side panels 6 and are fixedly connected to the upper end of the tie rod 4. The lower end of the tie rod 4 is rotatably connected to the telescopic end of the hydraulic cylinder 5. The lower end of the hydraulic cylinder 5 is mounted on the base 7. The connector 8 includes a horizontal plate 81, a vertical plate 82, and a fixing sleeve 83. The horizontal plate 81 is fixed below the discharge cover 2. A vertical plate 82 is mounted vertically above the horizontal plate 81. One end of the vertical plate 82 is fixedly connected to a fixing sleeve 83, which is mounted on the rotating shaft 3. The connector 8 is designed in two sets. The vertical plate 82 of the connector 8 is designed as two pieces. The structural design of the connector ensures that the discharge cover can be firmly fixed and supported to ensure the stability of the structure. The vertical plate 82 of the connector 8 is designed as a triangular plate. The upper edge of the triangular plate is fixedly connected to the horizontal plate 81, and the raised corners of the lower end of the triangular plate are reserved with connection holes. The triangular plate design and the reserved connection holes are to prevent the hydraulic cylinders on both sides from failing to work. The spare hydraulic cylinders 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 base. The discharge cover is designed to be a contoured cover plate with the same upper end face as the bottom of the cylinder body. The contoured cover plate coincides with 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 agitator assembly in the cylinder body.
[0016] When the present invention is used, the discharge cover needs to be opened to discharge the material. First, the locking cylinder of the locking mechanism controls the contraction of the U-shaped card, and the U-shaped card withdraws to one side from the outside of the upper card and the lower card, so that the discharge cover can be flipped. Then the hydraulic cylinder contracts and pulls the pull rod, which rotates with the rotating shaft. The rotating shaft drives the discharge cover to rotate downward and open synchronously through the connecting piece. After opening, the semi-dry material falls directly from the discharge port into the material receiving mechanism below, which is safe and reliable. The hydraulic cylinder is designed on the outside of the side plate of the cylinder body, and no hydraulic oil will leak into the semi-dry material, ensuring the cleanliness of the semi-dry material. When the discharge cover is closed, the hydraulic cylinder can extend in the opposite direction. After closing in place, the locking mechanism is activated, and the locking cylinder controls the extension of the U-shaped card, which is clamped from one side of the upper card and the lower card to the upper and lower sides, and is locked by the cooperation of the inner and outer inclined surfaces. The hydraulic cylinder assembly does not require continuous oil supply to work, which is safe and reliable.
