[0004] To solve the above problems, a closed vibrating conveyor is proposed. Summary of the invention

[0005] The object of the present invention is to provide a closed vibrating conveyor, which solves the problems in the background technology.

[0006] To achieve the above-mentioned purpose, the present invention provides the following technical solutions: a closed vibrating conveyor, comprising a plurality of sealed conveying pipes, and an exciting body arranged at the lower end of the sealed conveying pipes, a middle connecting pipe body is installed between every two groups of the sealed conveying pipes, a dispersing mechanism is installed in the cavity of the middle connecting pipe body, the dispersing mechanism comprises two groups of slide rail bodies fixedly installed on the inner wall of the middle connecting pipe body, and an electric motor arranged between the two groups of slide rail bodies, the output end of the electric motor is fixedly connected to an output rod, and the lower end of the output rod is fixedly connected to the dispersing body.

[0007] Furthermore, the scattering body is a spherical spring structure, and the scattering body is a component made of beryllium bronze, which is elastic and deformable.

[0008] Furthermore, the outer walls of the two groups of slide rail bodies are respectively slidably connected to the first slider and the second slider, one side of the first slider is fixedly connected to the first gear rod, one side of the second slider is fixedly connected to the second gear rod, and the first gear rod and the second gear rod are arranged opposite to each other on the sides where the teeth are provided.

[0009] Furthermore, an incomplete gear is provided on the side opposite to the first gear rod and the second gear rod, and the incomplete gear is provided with teeth only on half of its outer wall, and the incomplete gear is respectively meshed and connected with the first gear rod and the second gear rod, and both ends of the first gear rod and the second gear rod are fixedly connected with a side top assembly, and the side top assembly is used to push the connection between the dynamic sealing conveying pipe and the middle pipe body.

[0010] Furthermore, when the incomplete gear is in meshing state with the first gear rod, both the first gear rod and the second gear rod will drive the side top assembly to move to the left, and when the incomplete gear is in meshing state with the second gear rod, both the first gear rod and the second gear rod will drive the side top assembly to move to the right.

[0011] Furthermore, the side top assembly includes an external block fixedly connected to the first gear rod and the second gear rod, the inner wall of the external block is slidably connected to a top block body, one end of the top block body close to the external block is axially connected to a first connecting rod and a second connecting rod, one end of the first connecting rod away from the top block body is axially connected to a first pressure block, and one end of the second connecting rod away from the top block body is axially connected to a second pressure block.

[0012] Furthermore, the first pressing block and the second pressing block are symmetrically distributed about the center of the external block.

[0013] Furthermore, the first pressing block and the second pressing block are both slidably connected to the bottom of the cavity of the external block, and a return spring is fixedly connected between the first pressing block and the second pressing block.

[0014] Furthermore, when the return spring is in a relaxed state, the outer wall of the top block body protrudes out of the inner cavity of the external connection block.

[0015] Another technical solution proposed by the present invention is to provide an implementation method of a closed vibrating conveyor, comprising the following steps:

[0016] S1: The vibration body is used to drive the sealed conveying pipe to vibrate regularly, so that the particle mixture moves, and the driving motor drives the output rod to rotate, and the output rod drives the scattering body to rotate, so that whenever the particle mixture moves to the inner wall of the middle pipe body, it will be scattered by the scattering body;

When the incomplete gear is in meshing state with the second gear rod and the incomplete gear continues to rotate, the first gear rod and the second gear rod will both drive the side top assembly to move to the right. Therefore, while the scattering main body is performing the scattering operation, the side top assembly will continuously push the connection between the sealing conveying pipe and the middle pipe main body;

[0018] S3: When the side push assembly pushes the connection, the push block body will be pressed to move into the cavity of the external connection block, thereby driving the first connecting rod and the second connecting rod to deflect at an angle, driving the first pressure block and the second pressure block to move away from each other, thereby tightening the reset spring. Under the continuous reaction force of the reset spring, the push block body continues to vibrate, so that the push block body will perform high-frequency pushing when it contacts the connection next time.

[0019] Compared with the prior art, the present invention has the following beneficial effects:

[0020] 1. A closed vibrating conveyor, wherein a driving motor drives an output rod to rotate by using the motor, and drives a dispersing body to rotate by means of the output rod. Thus, whenever a granular mixed material moves to the inner wall of a middle connecting pipe body, it will be dispersed by the dispersing body to avoid stratification of materials with different particle sizes and densities. Since the dispersing body is a spherical spring structure, the dispersing body will be forced to bounce back and forth during the dispersing operation, thereby improving the dispersing efficiency and solving the problem that when conveying mixed materials with different particle sizes or densities, the vibration may cause the materials to be stratified and segregated. The materials with smaller particle size or larger density are easy to sink to the bottom, while the materials with larger particle size or smaller density may float on the upper layer, resulting in uneven composition of the conveyed materials.

[0021] 2. A closed vibrating conveyor, when the incomplete gear is in meshing state with the first gear rod and the incomplete gear continues to rotate, the first gear rod and the second gear rod will both drive the side top assembly to move to the left, and when the incomplete gear is in meshing state with the second gear rod and the incomplete gear continues to rotate, the first gear rod and the second gear rod will both drive the side top assembly to move to the right. Therefore, while the dispersing main body is performing the dispersing operation, the side top assembly will continuously push the connection between the sealed conveying pipe and the middle pipe main body, which can reduce the particles stuck in the connection.

[0029] The following will be combined with the drawings in the embodiments of the present invention to clearly and completely describe the technical solutions in the embodiments of the present invention. Obviously, the described embodiments are only part of the embodiments of the present invention, not all of the embodiments. Based on the embodiments of the present invention, all other embodiments obtained by ordinary technicians in this field without creative work are within the scope of protection of the present invention.

[0030] In order to solve the technical problem that when conveying mixed materials of different particle sizes or densities, vibration may cause stratification and segregation of materials. Materials with smaller particle sizes or higher densities tend to sink to the bottom, while materials with larger particle sizes or lower densities may float on the upper layer, resulting in uneven composition of the conveyed materials. Figure 1-6 As shown, the following preferred technical solutions are provided:

[0031] A closed vibrating conveyor comprises a plurality of sealed conveying pipes 1 and an exciting body 2 arranged at the lower end of the sealed conveying pipes 1, a middle connecting pipe body 3 is installed between every two groups of sealed conveying pipes 1, a dispersing mechanism 4 is installed in the cavity of the middle connecting pipe body 3, the dispersing mechanism 4 comprises two groups of slide rail bodies 41 fixedly installed on the inner wall of the middle connecting pipe body 3, and a motor 42 arranged between the two groups of slide rail bodies 41, an output end of the motor 42 is fixedly connected with an output rod, and the lower end of the output rod is fixedly connected with a dispersing body 43, the dispersing body 43 is a spherical spring structure, and the dispersing body 43 is a component made of beryllium bronze, which is elastic and deformable.

[0032] Specifically, when the sealed conveying pipe 1 conveys the granular mixed material, the excitation body 2 is used to drive the sealed conveying pipe 1 to vibrate regularly, so that the granular mixed material moves, and the driving motor 42 uses the motor 42 to drive the output rod to rotate, and the output rod drives the dispersing body 43 to rotate. Therefore, whenever the granular mixed material moves to the inner wall of the middle connecting pipe body 3, it will be dispersed by the dispersing body 43 to avoid stratification of materials with different particle sizes and densities. Since the dispersing body 43 is a spherical spring structure, the dispersing body 43 will be forced to bounce back and forth during the dispersing operation, thereby improving the dispersing efficiency and solving the problem that when conveying mixed materials with multiple particle sizes or densities, vibration may cause stratification and segregation of materials. Materials with smaller particle sizes or larger densities are easy to sink to the bottom, while materials with larger particle sizes or smaller densities may float on the upper layer, resulting in uneven composition of the conveyed materials.

[0033] The outer walls of the two sets of slide rail bodies 41 are respectively slidably connected to the first slider 44 and the second slider 45. A first toothed rod 46 is fixedly connected to one side of the first slider 44, and a second toothed rod 47 is fixedly connected to one side of the second slider 45. The first toothed rod 46 and the second toothed rod 47 are arranged opposite to each other on one side where the teeth are provided. An incomplete gear 48 is arranged on the side opposite to the first toothed rod 46 and the second toothed rod 47. The incomplete gear 48 is only provided with teeth on half of its outer wall, and the incomplete gear 48 is respectively connected to the first toothed rod 46 and the second toothed rod 47. 47 is meshedly connected, and both ends of the first gear rod 46 and the second gear rod 47 are fixedly connected with a side top assembly 49, and the side top assembly 49 is used to push and seal the connection between the conveying pipe 1 and the middle pipe body 3. When the incomplete gear 48 is in a meshing state with the first gear rod 46, the first gear rod 46 and the second gear rod 47 will drive the side top assembly 49 to move to the left. When the incomplete gear 48 is in a meshing state with the second gear rod 47, the first gear rod 46 and the second gear rod 47 will drive the side top assembly 49 to move to the right.

[0034] Specifically, when the motor 42 drives the output rod to rotate, the output rod will synchronously drive the incomplete gear 48 to rotate. When the incomplete gear 48 is in a meshing state with the first gear rod 46 and the incomplete gear 48 continues to rotate, the first gear rod 46 and the second gear rod 47 will both drive the side top assembly 49 to move to the left. When the incomplete gear 48 is in a meshing state with the second gear rod 47 and the incomplete gear 48 continues to rotate, the first gear rod 46 and the second gear rod 47 will both drive the side top assembly 49 to move to the right. Therefore, while the dispersing body 43 is performing the dispersing operation, the side top assembly 49 will continuously push the connection between the sealing conveying pipe 1 and the middle pipe body 3, which can reduce the number of particles stuck in the connection.

[0035] The side top assembly 49 includes an external block 491 fixedly connected to the first gear rod 46 and the second gear rod 47, the inner wall of the external block 491 is slidably connected to a top block body 492, one end of the top block body 492 close to the external block 491 is axially connected to a first connecting rod 493 and a second connecting rod 494, one end of the first connecting rod 493 away from the top block body 492 is axially connected to a first pressing block 495, and one end of the second connecting rod 494 away from the top block body 492 is axially connected to a second pressing block 496, the first pressing block 495 and the second pressing block 496 are symmetrically distributed about the center of the external block 491, the first pressing block 495 and the second pressing block 496 are both slidably connected to the bottom of the cavity of the external block 491, a return spring 497 is fixedly connected between the first pressing block 495 and the second pressing block 496, and when the return spring 497 is in a relaxed state, the outer wall of the top block body 492 protrudes out of the inner cavity of the external block 491.

[0036] Specifically, when the side top assembly 49 pushes the connection, the top block body 492 will be pressed to move into the cavity of the external connection block 491, thereby driving the first connecting rod 493 and the second connecting rod 494 to deflect at an angle, driving the first pressure block 495 and the second pressure block 496 to move away from each other, thereby tightening the reset spring 497. When the top block body 492 is away from the connection, the top block body 492 will continue to vibrate under the continuous reaction force of the reset spring 497, so that the top block body 492 will perform high-frequency pushing when it contacts the connection next time, further reducing the number of particles stuck in the connection.

[0037] In order to further better explain the above embodiment, the present invention also provides an implementation scheme, a method for implementing a closed vibrating conveyor, comprising the following steps:

[0038] Step 1: The excitation body 2 is used to drive the sealed conveying pipe 1 to vibrate regularly, so that the particle mixture moves, and the driving motor 42 drives the output rod to rotate, and the output rod drives the scattering body 43 to rotate, so that whenever the particle mixture moves to the inner wall of the middle pipe body 3, it will be scattered by the scattering body 43;

[0039] Step 2: When the motor 42 drives the output rod to rotate, the output rod will synchronously drive the incomplete gear 48 to rotate. When the incomplete gear 48 is in meshing state with the first gear rod 46 and the incomplete gear 48 continues to rotate, the first gear rod 46 and the second gear rod 47 will both drive the side top assembly 49 to move leftward. When the incomplete gear 48 is in meshing state with the second gear rod 47 and the incomplete gear 48 continues to rotate, the first gear rod 46 and the second gear rod 47 will both drive the side top assembly 49 to move rightward. Therefore, while the scattering main body 43 is performing the scattering operation, the side top assembly 49 will continuously push the connection between the sealing conveying pipe 1 and the middle pipe main body 3.

[0040] Step three: When the side push assembly 49 pushes the connection, the push block body 492 will be pressed to move into the cavity of the external connection block 491, thereby driving the first connecting rod 493 and the second connecting rod 494 to deflect at an angle, driving the first pressure block 495 and the second pressure block 496 to move away from each other, thereby tightening the reset spring 497. Under the continuous reaction force of the reset spring 497, the push block body 492 continues to vibrate, so that the push block body 492 will perform high-frequency pushing when it contacts the connection next time.
