[0010] Figure 1 This is a schematic diagram of the structure of the unloading gate of a vertical shaft planetary gear mixing station according to this utility model.
[0011] Figure 2 This is a schematic diagram of the bottom structure of the unloading gate of a vertical shaft planetary gear mixing plant according to this utility model. Detailed Implementation
[0012] The specific embodiments of this utility model will be further described in detail below with reference to the accompanying drawings.
[0013] Depend on Figures 1 to 2 It is known that a discharge gate for a vertical shaft planetary gear mixing plant includes a rotating shaft 2 installed on the outer wall 1 of the mixing plant. The bottom of the rotating shaft 2 is detachably connected to a discharge gate 3. A first hydraulic cylinder 4 is movably installed on the outer wall 1 of the mixing plant. The telescopic rod of the first hydraulic cylinder 4 is movably connected to the discharge gate 3, forming a structure in which the hydraulic cylinder controls the opening of the discharge gate 3. Multiple first wedge blocks 5 are provided at the bottom of the discharge gate 3. Multiple second hydraulic cylinders 6 are provided at the bottom of the mixing plant. The end of the telescopic rod of the second hydraulic cylinder 6 is provided with a second wedge block 7 that cooperates with the first wedge block 5.
[0014] In practical use, this utility model
[0015] The unloading gate 3 is installed at the bottom of the outer wall 1 of the mixing plant via the rotating shaft 2, and connected to the telescopic rod of the first hydraulic cylinder 4 to realize the structure of the first hydraulic cylinder 4 controlling its rotation. After it rotates and closes the outlet of the mixing plant, the first wedge block 5 and the second wedge block 7 are aligned. The second hydraulic cylinder 6 pushes the second wedge block 7 to cooperate with the first wedge block 5. Under the action of the wedge surface, the unloading gate 3 is pushed towards the mixing plant, so that the unloading gate 3 is more stable under force and reduces deformation.
[0016] In this device, the rotating shaft 2 includes a fixed ring 8 set on the outer wall 1 of the mixing station, and a collar 9 is rotatably set inside the fixed ring 8. The discharge gate 3 is threadedly connected to the collar 9 by screws 10.
[0017] The discharge gate 3 can be replaced and maintained by removing screw 10, and the relative height of screw 10 and collar 9 can be adjusted by rotating to prevent leakage from the mixing plant.
[0018] The discharge gate 3 has a fan-shaped structure, and a fan-shaped outlet is opened at the bottom of the mixing plant. The size of the discharge gate 3 is larger than the size of the bottom outlet of the mixing plant, so that the discharge gate 3 can completely block the outlet and prevent leakage.
[0019] The bottom of the mixing plant is equipped with a support block 11 that is sleeved on the outside of the telescopic rod of the second hydraulic cylinder 6. The support block 11 is close to the outlet of the mixing plant and does not affect the opening and closing of the unloading gate 3. The support block 11 assists in supporting the telescopic rod of the second hydraulic cylinder 6 to prevent it from being deformed due to excessive force, thus ensuring the support force for the unloading gate 3.
[0020] The contact surfaces of the first wedge block 5 and the second wedge block 7 form an angle of 15-20° with the horizontal plane, which allows the smaller pushing force of the second hydraulic cylinder 6 to generate greater pressure, pressing the unloading gate 3 onto the outlet and preventing the unloading gate 3 from tilting and opening due to excessive material gravity.
[0021] In this device, the telescopic rod of the first hydraulic cylinder 4 is sleeved with the connecting pin on the unloading gate 3, and the rotating shaft 2 adopts a threaded connection. Therefore, the unloading gate 3 is easy to disassemble, replace and maintain.
[0022] The first wedge block 5 is fixed to the bottom of the unloading gate 3 with screws, and the second wedge block 7 is fixed to the end of the telescopic rod of the second hydraulic cylinder 6 with screws for easy replacement. Different sizes of the first wedge block 5 and the second wedge block 7 can also be selected according to different situations.
[0023] Compared with the prior art, this utility model has the following advantages: a support structure is added to the bottom of the unloading gate to help support the material and reduce deformation; the unloading gate is easy to replace; the wedge blocks used for support are also easy to replace, maintenance is simple, and maintenance avoids affecting the use of the equipment.
