Description

Technical Field

[0001] This utility model relates to the field of material handling equipment technology, specifically to a silo unloading device. Background Technology

[0002] In industrial production, the performance of the hopper discharge device directly affects the continuity and stability of the production line. Currently, there are two main discharge methods: First, an electric gate valve is installed at the hopper discharge port, relying on the material's own gravity to discharge; second, a rotary feeder is installed in the discharge pipe, where the material enters the discharge pipe under gravity and is discharged by the rotary feeder's actuation.

[0003] However, existing silo feeding devices still have significant drawbacks: when the material has a high moisture content or is prone to sticking or bridging, uneven feeding or even poor feeding will occur, seriously affecting the stable operation of subsequent processes; when using a rotary feeder, the frequent friction between the material and the equipment will cause the rotary feeder to wear out quickly, increasing equipment maintenance costs; in addition, after the material is stored in the silo for a long time, it is easy to absorb moisture from the air and expand and clump, further aggravating the difficulty of feeding. Therefore, we propose a silo feeding device. Utility Model Content

[0004] In view of the problems existing in the above-mentioned material unloading devices, this utility model is proposed.

[0005] Therefore, the purpose of this utility model is to provide a silo feeding device that solves the significant defects of existing silo feeding devices: when the material has a high moisture content or is prone to sticking or bridging, uneven feeding or even poor feeding will occur, seriously affecting the stable operation of subsequent processes; when using a rotary feeder, the frequent friction between the material and the equipment will cause the rotary feeder to wear out quickly, increasing equipment maintenance costs; in addition, after the material is stored in the silo for a long time, it is easy to absorb moisture from the air and expand and clump, further aggravating the problem of feeding difficulties.

[0006] To achieve the above objectives, this utility model provides the following technical solution:

[0007] A hopper unloading device includes a hopper, a unloading port, and a unloading pipe. The unloading port is fixedly installed at the bottom of the hopper, and the unloading pipe is fixedly installed at the bottom of the unloading port. A unloading cone is slidably disposed inside the unloading port. A bearing is fixedly installed through the bottom of the unloading cone. A first connecting pipe is fixedly installed at the bottom of the inner ring of the bearing. A second connecting pipe is fixedly installed on one side of the bottom of the first connecting pipe. An mounting plate is fixedly installed on one side of the unloading pipe. A telescopic rod is fixedly installed at the bottom of the mounting plate. The movable end of the telescopic rod is fixedly connected to the surface of the second connecting pipe.

[0008] Preferably, a limiting groove is provided through one side of the feeding pipe, the second connecting pipe is slidably connected through the limiting groove, and a guide plate is fixedly installed on the inner wall surface of the feeding pipe at the top of the limiting groove.

[0009] Preferably, the first connecting pipe has a first rotating shaft inside, a fixing plate is fixedly installed on the top of the first rotating shaft, and fixing columns are fixedly installed on both sides of the fixing plate, and the other ends of the two fixing columns are fixedly connected to the inside of the feeding cone.

[0010] Preferably, a motor is fixedly installed on one side inside the second connecting pipe, a second rotating shaft is fixedly installed on the output end of the motor, a first bevel gear is fixedly installed on one side of the second rotating shaft, and a second bevel gear is fixedly installed on the other side of the first rotating shaft, with the first bevel gear and the second bevel gear meshing together.

[0011] Preferably, the surface of the feeding cone is uniformly provided with multiple ventilation holes, and multiple ribs are fixedly installed on the surface of the feeding cone.

[0012] Preferably, a hot air duct is fixedly installed at the bottom of the second connecting pipe, and a solenoid valve is fixedly installed on the surface of the hot air duct.

[0013] The technical effects and advantages provided by this utility model in the above technical solution are as follows:

[0014] 1. This utility model utilizes ribs on the surface of the feeding cone to effectively agitate the material layer during rotation, breaking down the adhesion and bridging structures of the material. Simultaneously, hot air is ejected through the vents to form an air cushion, further preventing material accumulation on the cone surface. This dual action ensures uniform and smooth feeding, solving the problems of high moisture content, easy adhesion, and difficulty in feeding when materials are bridging. At the same time, the hot air cushion forms a buffer layer between the material and the feeding cone, avoiding direct friction between the material and the cone. Compared with traditional rotary feeders, the contact method between the rotating component (feeding cone) and the material in this device is more optimized, reducing equipment wear caused by frequent friction and lowering maintenance costs.

[0015] 2. This utility model uses an external hot air source to enter the material feeding cone through a hot air pipe, a second connecting pipe, and a first connecting pipe. After being sprayed out through the vent, it can dry the material, effectively reducing the possibility of the material expanding and caking due to absorbing moisture from the air, and improving the material feeding performance. At the same time, the telescopic rod can drive the material feeding cone to move up and down. By adjusting the gap between the material feeding cone and the feeding port, the cross-sectional area of ​​the feeding channel can be precisely controlled, thereby achieving the adjustment of the feeding speed. Furthermore, the rotation speed of the motor-driven material feeding cone can also be adjusted according to the material characteristics, further optimizing the feeding control.

[0023] To enable those skilled in the art to better understand the technical solution of this utility model, the present utility model will be further described in detail below with reference to the accompanying drawings.

[0024] This utility model discloses a hopper unloading device.

[0025] This utility model provides, for example Figure 1-4 The illustrated material feeding device includes a material hopper 1, a feeding port 2, and a feeding pipe 3. The feeding port 2 is fixedly installed at the bottom of the material hopper 1, and the feeding pipe 3 is fixedly installed at the bottom of the feeding port 2. A feeding cone 4 is slidably provided inside the feeding port 2. A bearing 5 is fixedly installed through the bottom of the feeding cone 4. A first connecting pipe 6 is fixedly installed at the bottom of the inner ring of the bearing 5. A second connecting pipe 7 is fixedly installed on one side of the bottom of the first connecting pipe 6. An installation plate 8 is fixedly installed on one side of the feeding pipe 3. A telescopic rod 9 is fixedly installed at the bottom of the installation plate 8. The moving end of the telescopic rod 9 is fixedly connected to the surface of the second connecting pipe 7 to facilitate adjustment of the feeding speed.

[0026] This utility model discloses a material unloading device for a hopper. A limiting groove 10 is provided through one side of the unloading pipe 3. The second connecting pipe 7 is slidably connected to the inside of the limiting groove 10. A guide plate 11 is fixedly installed on the inner wall surface of the unloading pipe 3 at the top of the limiting groove 10 to facilitate the up and down movement of the unloading cone 4.

[0027] This utility model discloses a hopper unloading device. A first rotating shaft 12 is provided inside the first connecting pipe 6. A fixing plate 13 is fixedly installed on the top of the first rotating shaft 12. Fixing columns 14 are fixedly installed on both sides of the fixing plate 13, and the other ends of the two fixing columns 14 are fixedly connected to the interior of the unloading cone 4. A motor 15 is fixedly installed on one side inside the second connecting pipe 7. A second rotating shaft 16 is fixedly installed at the output end of the motor 15. A first bevel gear 17 is fixedly installed on one side of the second rotating shaft 16. A second bevel gear 18 is fixedly installed on one side of the first rotating shaft 12. The first bevel gear 17 and the second bevel gear 18 mesh with each other, facilitating the rotation of the unloading cone 4.

[0028] This utility model discloses a material feeding device for a hopper. The surface of the feeding cone 4 is uniformly provided with a plurality of ventilation holes 19, and a plurality of ribs 20 are fixedly installed on the surface of the feeding cone 4, which can loosen the material layer and prevent adhesion and bridging in the hopper.

[0029] This utility model discloses a material feeding device for a hopper. A hot air pipe 21 is fixedly installed at the bottom of the second connecting pipe 7, and a solenoid valve 22 is fixedly installed on the surface of the hot air pipe 21, which can dry materials.

[0030] In use, the moving end of the telescopic rod 9 pushes the second connecting pipe 7, causing the first connecting pipe 6 and the feeding cone 4 to slide up and down within the feeding port 2. When the telescopic rod 9 extends, the feeding cone 4 moves downward, forming an annular feeding channel with the inner wall of the feeding port 2, and the material enters the feeding pipe 3 under gravity. When the telescopic rod 9 retracts, the feeding cone 4 moves upward until it fits against the inner wall of the feeding port 2, closing the feeding channel and stopping the feeding. Then, the motor 15 is started. The motor 15 drives the first bevel gear 17 to rotate through the second rotating shaft 16. The meshing second bevel gear 18 then drives the first rotating shaft 12 to rotate, thereby driving the fixed plate 13 and the feeding cone 4 to rotate. During the rotation, the ribs 20 on the surface of the feeding cone 4 agitate the material at the bottom of the hopper 1 to prevent material adhesion and bridging. At the same time, the hot air duct 21... Hot air enters the first connecting pipe 6 under the control of the solenoid valve 22 and is ejected through the vent 19 on the surface of the feeding cone 4, forming an air cushion. This reduces friction between the material and the cone and breaks up the bridging structure of the material, ensuring smooth feeding. Hot air generated by an external hot air source enters the internal space of the feeding cone 4 through the hot air pipe 21, solenoid valve 22, second connecting pipe 7, and first connecting pipe 6. After being ejected from the vent 19, it directly acts on the material to dry it, reduce its moisture content, prevent the material from expanding and caking after long-term storage, and improve feeding performance. The second connecting pipe 7 slides in the limiting groove 10 to ensure the stability of the feeding cone 4's up-and-down movement. The guide plate 11 guides the material to enter the feeding pipe 3 evenly, avoiding material accumulation at the feeding port 2, further ensuring the uniformity and smoothness of feeding.
