Description

Technical Field

[0001] This utility model relates to the field of bottom unloading technology, specifically a bottom unloader. Background Technology

[0002] The bottom vibrating unloader is suitable for bottom unloading of powdery materials such as flour, feed, chemicals, and pharmaceuticals. Traditional vibrating unloaders can cause material to arch inside the silo, making it impossible for the material to flow out of the outlet slowly and evenly. The material stored in the silo is prone to arching due to pressure and the adhesion and cohesion between material particles, which can cause blockage and affect normal production.

[0003] Application number CN201921126342.2 discloses a bottom unloader, belonging to the technical field of mechanical equipment. It includes a silo, with the inner diameter of the silo fixedly connected to the lower flange. A material inlet is provided above the silo, and the material inlet is fixedly connected to the inner diameter of the upper flange. The silo and the material inlet are fixedly connected by an annular silicone connector. Several screws are inserted between the upper and lower flanges, and matching nuts are fitted at both ends of the screws. When using the bottom unloader, the vibrating motor is turned on, and the vibrating motor starts working. When the material falls from the material inlet into the silo, the annular silicone connector and spring effectively reduce the force transmitted to the material inlet, preventing the connecting screws from loosening. The arch breaker inside the silo is cone-shaped. This design allows the material falling into the silo to be broken by the cone-shaped arch breaker, thus dispersing the material.

[0004] During use, the unloader has an unstable unloading effect on materials with large particle size differences (such as mixed sand and gravel). The material flow depends on the vibration intensity, and the speed fluctuates greatly. The unloading efficiency will decrease with the vibration frequency. Furthermore, long-term high-frequency vibration will cause cracking of weld points, loosening of bolts, shortening of equipment life, and frequent replacement of vulnerable parts such as vibration springs and vibrators, thus increasing maintenance costs. Utility Model Content

[0005] The purpose of this invention is to provide a bottom unloader that solves the problem of stable material feeding for different materials.

[0006] To solve the above-mentioned technical problems, this utility model is achieved through the following technical solution:

[0007] This utility model relates to a bottom unloader, comprising a hopper and an unloading assembly. The unloading assembly is installed on the inner wall of the bottom surface of the hopper. The hopper includes a storage frame, and a motor is fixedly installed on the inner wall of the bottom surface of the storage frame. The shaft of the motor extends upward through to the top of the storage frame. A bidirectional hinge block is fixedly installed at the top of the motor. One end of the bidirectional hinge block is provided with a long cylindrical rod. A set of spiral toothed blocks are provided on the outer wall of the long cylindrical rod. A pulley is rotatably connected to the top of the long cylindrical rod. The purpose of this design is that, during the operation of the unloader, material enters from the upper frame, flows downwards along the inner wall of the conical hopper's inclined surface, and is concentrated in the storage frame. The inclined structure of the conical hopper guides the material to fall naturally, forming initial material aggregation. The motor is then started, and the motor shaft drives the stirring blades in the center of the storage frame to rotate at high speed, stirring the material in the frame, breaking up adhesions, preventing material accumulation and clumping, and ensuring good material flowability. The motor shaft continues to rotate, driving the long cylindrical rod to rotate via a bidirectional hinge block. The spiral teeth around the long cylindrical rod adhere closely to the inner wall of the conical hopper, pushing the material along the inner wall towards the bottom of the storage frame, further streamlining the material flow path. The pulley at the top of the long cylindrical rod slides on a rail on the inner wall of the frame, providing stable guidance for the rotation of the long cylindrical rod and ensuring the spiral teeth maintain their position. The material is continuously and evenly pushed, avoiding the swaying of the long cylindrical rod which affects the unloading efficiency. After being stirred and pushed by the spiral, the material gathers in the discharge troughs on both sides of the bottom of the storage frame and is discharged from the unloader through the discharge troughs, completing the entire unloading process. During this process, the positioning seat and the rack ring help maintain the structural stability of the conical bucket and the long cylindrical rod, ensuring a smooth and unobstructed unloading process. A two-way hinge block is used to connect the motor shaft and the long cylindrical rod, optimizing the power transmission method. The long cylindrical rod, in conjunction with the spiral toothed block, pushes the material close to the inner wall of the conical bucket. At the same time, the pulley at the top of the long cylindrical rod slides in conjunction with the slide rail on the inner wall of the frame, providing stable guidance for the rotation of the long cylindrical rod, ensuring that the spiral pushing process is efficient and stable. The spiral pushing and stirring functions work together to adapt to the unloading needs of various types of materials such as granular and powdery materials, and perform better for materials with poor flowability or easy agglomeration.

[0008] Furthermore, the motor shaft has stirring blades on its outer perimeter, positioned at the center of the storage frame. This arrangement ensures that during operation, the motor shaft drives the stirring blades at the center of the storage frame to rotate at high speed, stirring the material within the frame, breaking up adhesions, preventing clumping, and maintaining good flowability.

[0009] Furthermore, a conical hopper is fixedly connected to the top of the storage frame, and the long cylindrical rod and the spiral toothed block are close to the inner wall of one side of the conical hopper. The purpose of this arrangement is that during the use of this unloader, the long cylindrical rod is driven to rotate by the bidirectional hinge block, and the spiral toothed block around the long cylindrical rod is close to the inner wall of the conical hopper, pushing the material along the inner wall of the conical hopper towards the bottom of the storage frame, further streamlining the material flow path.

[0010] Furthermore, a set of positioning seats is provided on the inner wall around the bottom of the conical hopper. A rack ring is fixedly connected to the outer wall of one side adjacent to the positioning seats. The positioning seats and the rack ring are located in the gap between the conical hopper and the long cylindrical rod. The purpose of this arrangement is that during the use of the unloader, the material is discharged through the discharge chute, completing the entire unloading process. During this process, the positioning seats and the rack ring help maintain the structural stability of the conical hopper and the long cylindrical rod, ensuring a smooth and unobstructed unloading process.

[0011] Furthermore, the bottom two outer walls of the storage frame are provided with discharge troughs, and the top of the conical hopper is fixedly connected to a frame around its perimeter. The purpose of this arrangement is that, during the use of the unloader, the material, after being stirred and spirally pushed, gathers in the discharge troughs on both sides of the bottom of the storage frame, and is discharged from the unloader through the discharge troughs, completing the entire unloading process. The pulley at the top of the long cylindrical rod slides in conjunction with the slide rail on the inner wall of the frame, providing stable guidance for the rotation of the long cylindrical rod.

[0012] Furthermore, a slide rail is provided on the inner wall around the connection between the frame and the conical hopper, and the pulley is slidably connected to the inner wall of the slide rail. The purpose of this arrangement is that, during the use of this unloader, the pulley at the top of the long cylindrical rod slides in cooperation with the slide rail on the inner wall of the frame, providing stable guidance for the rotation of the long cylindrical rod and ensuring that the spiral pushing process is efficient and smooth.

[0013] This utility model has the following beneficial effects:

[0014] (1) This utility model uses a motor, a spiral toothed block and a pulley to connect the motor shaft and the long round rod with a two-way hinge block. The long round rod works with the spiral toothed block to push the material close to the inner wall of the conical bucket. The pulley at the top of the long round rod slides with the slide rail on the inner wall of the frame. The spiral pushing and stirring functions work together to meet the unloading needs of various types of materials such as granules and powders. It performs better for materials with poor flowability or easy agglomeration.

[0015] (2) By setting the stirring blades, the motor shaft drives the stirring blades located in the center of the storage frame to rotate at high speed, stirring the material in the storage frame, breaking the adhesion between the materials, preventing the materials from accumulating and clumping, and ensuring that the materials maintain good fluidity.

Based on the embodiments of the present utility model, all other embodiments obtained by those of ordinary skill in the art without creative effort are within the protection scope of the present utility model.

[0025] Please see Figures 1-4As shown, this utility model is a bottom unloader, including a hopper 1 and an unloading assembly 2. The unloading assembly 2 is installed on the inner wall of the bottom surface of the hopper 1. The hopper 1 includes a storage frame 105. A motor 201 is fixedly installed on the inner wall of the bottom surface of the storage frame 105. The shaft of the motor 201 extends upward through to the top of the storage frame 105. A bidirectional hinge block 203 is fixedly installed at the top of the motor 201. One end of the bidirectional hinge block 203 is provided with a long round rod 204. A set of spiral toothed blocks 205 are provided on the outer wall of the long round rod 204. A pulley 207 is rotatably connected to the top of the long round rod 204. The purpose of this design is that, during the operation of the unloader, material enters from the upper frame 102, flows downward along the inclined inner wall of the conical hopper 101, and is concentrated in the storage frame 105. The inclined structure of the conical hopper guides the material to fall naturally, forming initial material aggregation. The motor 201 is then started, and its shaft drives the stirring blades 202 located in the center of the storage frame 105 to rotate at high speed, stirring the material in the storage frame 105, breaking up the adhesion between materials, preventing material accumulation and clumping, and ensuring good material flowability. The motor 201 shaft continues to rotate, driving the elongated rod 204 to rotate through the bidirectional hinge block 203. The spiral toothed blocks 205 around the elongated rod are in close contact with the inner wall of the conical hopper 101, pushing the material along the inner wall of the conical hopper towards the bottom of the storage frame 105, further streamlining the material flow path. The pulley 207 at the top of the elongated rod 204 slides on the slide rail 206 on the inner wall of the frame 102, providing stable guidance for the rotation of the elongated rod and ensuring the smooth operation of the spiral toothed blocks 205. The material is continuously and evenly pushed to prevent the long cylindrical rod 204 from shaking and affecting the unloading efficiency. The material, after being stirred and pushed by the spiral, gathers into the discharge troughs 106 on both sides of the bottom surface of the storage frame 105, and is discharged from the unloader through the discharge troughs 106, completing the entire unloading process. During this process, the positioning seat 103 and the rack ring 104 help maintain the structural stability of the conical bucket 101 and the long cylindrical rod 204, ensuring a smooth and unobstructed unloading process. A two-way hinge block 203 is used to connect the motor 201 shaft and the long cylindrical rod 204. Rod 204 optimizes the power transmission method. The long cylindrical rod 204, together with the spiral toothed block 205, pushes the material closely against the inner wall of the conical bucket 101. At the same time, the pulley 207 at the top of the long cylindrical rod slides and engages with the slide rail 206 on the inner wall of the frame 102, providing stable guidance for the rotation of the long cylindrical rod and ensuring that the spiral pushing process is efficient and smooth. The spiral pushing and stirring functions work together to adapt to the unloading needs of various types of materials such as granular and powdery materials, and perform better for materials with poor flowability or easy agglomeration.

[0026] The motor 201 has stirring blades 202 on the outer wall of its shaft, which are located in the center of the storage frame 105.

[0028] A set of positioning seats 103 is provided on the inner wall around the bottom of the conical bucket 101. A rack ring 104 is fixedly connected to the outer wall of the adjacent side of the positioning seats 103. The positioning seats 103 and the rack ring 104 are located in the gap between the conical bucket 101 and the long cylindrical rod 204. The purpose of this arrangement is that during the use of the unloader, the unloader is discharged through the discharge chute 106 to complete the entire unloading process.

[0029] The storage frame 105 has discharge troughs 106 on both sides of its bottom outer wall, and the top of the conical hopper 101 is fixedly connected to a frame 102. The purpose of this arrangement is that during the use of the unloader, the material, after being stirred and pushed by the spiral, gathers into the discharge troughs 106 on both sides of the bottom of the storage frame 105, and is discharged from the unloader through the discharge troughs 106, completing the entire unloading process. The pulley 207 at the top of the long cylindrical rod slides in cooperation with the slide rail 206 on the inner wall of the frame 102, providing stable guidance for the rotation of the long cylindrical rod 204.
