[0002] Blanking refers to the process of removing materials of a certain shape, quantity or quality from the entire material or batch of materials after determining the shape, quantity or quality of the materials required to make a certain equipment or product. The blanking hopper refers to the combination of a container and a transportation component used to fill the raw materials for blanking operations. The blanking hopper can be used in the material adding operation of mixing tanks and reaction tanks. In the actual working process, the blanking hopper is easily blocked during blanking, and the inner wall of the blanking pipe will adhere to the residual raw materials. Therefore, we have launched a blanking hopper with a vibration structure.

In order to facilitate material discharge, the existing material discharge hopper is mostly designed in a hopper shape, which is larger at the top and smaller at the bottom. It is easy to get blocked during material discharge, affecting the efficiency of material discharge; 2. The material discharge speed of the existing material discharge hopper is mostly fixed. When it is necessary to adjust the material discharge speed according to the processing speed, it is often necessary to replace the material discharge pipe with different diameters.

DETAILED DESCRIPTION

[0023] The following will be combined with the drawings in the embodiments of the utility model to clearly and completely describe the technical solutions in the embodiments of the utility model. Obviously, the described embodiments are only part of the embodiments of the utility model, not all of the embodiments. Based on the embodiments of the utility model, all other embodiments obtained by ordinary technical personnel in this field without creative work are within the scope of protection of the utility model.

[0024] See also Figures 1 to 6 The utility model provides a technical solution: a lower hopper with a vibration structure, comprising a hopper body 1, the hopper body 1 is movably inserted in the top annular groove of a lowering pipe 2, an annular mounting groove 3 is provided on the outer middle part of the lowering pipe 2, a vibration component 4 is provided in the middle part of the annular mounting groove 3, a dredging component 5 is provided in the middle part of the lowering pipe 2, and a diameter adjustment component 6 is fixedly connected to the bottom end of the lowering pipe 2;

[0025] The vibration assembly 4 includes a dual-axis motor 401 fixedly connected to one side of the blanking pipe 2 through two connecting plates. The top output end of the dual-axis motor 401 is fixedly connected with a main gear 402. One side of the main gear 402 meshes with a secondary toothed ring 403. The bottom surface of the secondary toothed ring 403 is fixedly connected with a rotating ring 404. The top surface of the secondary toothed ring 403 is fixedly connected with three vibration balls 405. The rotating ring 404 is rotatably connected in the bottom annular groove of the annular installation groove 3. The bottom surface of the hopper body 1 is fixedly connected with a plurality of springs 101 and a plurality of vertical rods 102 respectively. The bottom ends of the plurality of vertical rods 102 penetrate into the interior of the annular installation groove 3 and are connected with contact balls 103. The lowest point of the spherical surface of the contact ball 103 is lower than the highest point of the spherical surface of the vibration ball 405. By rotating the dual-axis motor 401 to drive the main gear 402 to rotate, the main gear 402 drives the meshing secondary toothed ring 403 to rotate. At this time, the vibration balls 405 on the top surface of the secondary toothed ring 403 will intermittently contact the upper contact balls 103. The vibration balls 405 will push up the contact balls 103. When the contact balls 103 rise, they will drive the hopper body 1 to rise through the vertical rods 102. When the hopper body 1 rises, it will stretch the springs 101. When the vibration balls 405 are separated from the contact balls 103, the springs 101 rebound to drive the hopper body 1 to move downward. Repeating like this can make the hopper body 1 vibrate up and down continuously. The vibration assembly 4 can accelerate the blanking speed of the hopper body 1, and when the vibration balls 405 are less than half of the complete sphere, this structure ensures that even when the contact balls 103 drop to the lowest point and contact the rotating vibration balls 405, they can still be pushed up by the vibration balls 405 and will not get stuck.

[0026] In this embodiment, as Figure 2 and Figure 5 shown, the dredging assembly 5 includes a main bevel gear 501 fixedly connected to the bottom output end of the dual-axis motor 401. One side of the main bevel gear 501 meshes with a secondary bevel gear 502. One side of the secondary bevel gear 502 is fixedly connected with a dredging shaft 503. The dredging shaft 503 extends into the interior of the blanking pipe 2. A plurality of groups of dredging rods 504 are arranged on the surface of the part of the dredging shaft 503 extending to the inner side of the blanking pipe 2. By driving the main bevel gear 501 to rotate through the dual-axis motor 401, when the main bevel gear 501 rotates, it will drive the secondary bevel gear 502 to rotate. When the secondary bevel gear 502 rotates, it will drive the dredging shaft 503 to rotate. The rotation of the dredging shaft 503 drives the dredging rods 504 to stir in the blanking pipe 2, and cooperating with the vibration assembly 4 can prevent the raw materials from being blocked in the blanking pipe 2.

[0027] In this embodiment, as Figure 2 、 Figure 4 and Figure 6As shown in the figure, the diameter adjustment assembly 6 includes a housing 601 fixedly connected to the bottom end of the blanking pipe 2. One side of the bottom surface of the housing 601 is fixedly connected with a reduction motor 602. A blanking port is formed in the middle of the housing 601, and the inner diameter of the blanking port is the same as that of the blanking pipe 2. The output end of the reduction motor 602 is fixedly connected with a driving gear 603. A gear ring 604 is meshed with one side of the driving gear 603. A rotating ring 605 is arranged at the bottom edge of the gear ring 604. The rotating ring 605 is slidably connected in the inner bottom groove of the housing 601. A plurality of arc-shaped connecting rods 606 are rotatably connected to the bottom surface of the gear ring 604 through a connecting shaft. One ends of the plurality of arc-shaped connecting rods 606 close to the middle of the housing 601 are all hinged with a sealing piece 607. The sealing piece 607 is rotatably connected to the inner top surface of the housing 601 through a connecting shaft. When it is necessary to adjust the blanking speed, the reduction motor 602 is driven to drive the driving gear 603 to rotate. The rotation of the driving gear 603 will drive the gear ring 604 to rotate. The gear ring 604 rotates with the rotating ring 605 rotating in the inner bottom groove of the housing 601. If the gear ring 604 rotates clockwise, the arc-shaped connecting rod 606 drives the sealing piece 607 to rotate around the connecting shaft where the sealing piece 607 is rotatably connected to the housing 601. At this time, the sealing piece 607 will contract into the housing 601, increasing the diameter of the blanking port. Similarly, vice versa, the size of the blanking port can be reduced. By controlling the size of the blanking port, the purpose of adjusting the blanking speed can be achieved.

[0028] The usage method and advantages of the present utility model: When the blanking hopper with a vibration structure is in use, the working process is as follows:

[0029] Such as Figure 1 、 Figure 2 、 Figure 3 、 Figure 4 、 Figure 5 and Figure 6As shown in the figure, first, the blanking pipe 2 is docked at the top of the processing equipment. Then, the size of the blanking port is adjusted as needed. The driving gear 603 is driven to rotate by the reduction motor 602. The rotation of the driving gear 603 drives the gear ring 604 to rotate. The rotation of the gear ring 604 causes the rotating ring 605 to rotate in the inner bottom groove of the housing 601. If the gear ring 604 rotates clockwise, the arc-shaped connecting rod 606 drives the sealing piece 607 to rotate around the connecting shaft where the sealing piece 607 is rotatably connected to the housing 601. At this time, the sealing piece 607 will contract into the housing 601, increasing the diameter of the blanking port. Vice versa, the size of the blanking port can be reduced. By controlling the size of the blanking port, the purpose of adjusting the blanking speed is achieved. While blanking, the dual-axis motor 401 is started. The vibration ball 405 on the top surface of the secondary gear ring 403 driven by the dual-axis motor 401 will intermittently contact the contact ball 103 above, causing the hopper body 1 to be continuously lifted and dropped, generating vibration. The dual-axis motor 401 can also drive the main bevel gear 501 to rotate. When the main bevel gear 501 rotates, it drives the secondary bevel gear 502 to rotate. The rotation of the secondary bevel gear 502 drives the dredging shaft 503 to rotate. The rotation of the dredging shaft 503 drives the dredging rod 504 to stir in the blanking pipe 2, cooperating with the vibration assembly 4 to prevent the raw materials from clogging in the blanking pipe 2.
