Description

Technical Field

[0001] The utility model relates to the field of material transportation, in particular to a vibration conveyor with stable material flow and height. Background Art

[0002] Commonly used vibrating conveyors cannot adjust to material flow fluctuations. When the material conveying volume is small, the material height is low, which has a greater impact on the accuracy of moisture detection. Even when conveying less material, if the incoming material flow fluctuates, it is easy to expose the trough at the bottom of the vibrating conveyor, affecting the detection accuracy of the moisture meter. For example:

[0003] Chinese utility model patent CN212711241U discloses a non-stick material rocker-arm vibrating conveyor, comprising a bracket, a frame, a trough, a balancing body, a rocker arm mounting base, a rocker arm, a balancing body linear drive device, a material guide chute, a material guide drum, a top plate, and a vibrating device. The balancing body linear drive device drives the balancing body to reciprocate linearly and drives the rocker arm to rotate about the rocker arm mounting base, thereby causing the trough to reciprocate linearly in the opposite direction of the balancing body. This solution also suffers from the problem of being unable to regulate material flow fluctuations. Utility Model Content

[0004] In response to the shortcomings of the existing technology, the purpose of the utility model is to provide a vibrating conveyor with stable material flow and height. When the incoming material flow fluctuates, the thicker part of the material can be evenly diluted so that the material flow is uniform when it reaches the moisture meter position; when the incoming material flow increases or decreases significantly, the elastic baffle can be adjusted to reduce or increase the height of the material flowing through the moisture meter position, keeping the material height within a reasonable range and ensuring the accuracy of material moisture detection.

[0005] In order to achieve the above purpose, the present invention is implemented through the following technical solutions:

[0006] An embodiment of the utility model provides a vibrating conveyor with stable material flow and height, including a trough body, a vibration mechanism connected to the bottom of the trough body, an elastic baffle symmetrically installed on the inner side of the outlet end of the trough body, a foldable screw is provided on the outer side of the elastic baffle, the foldable screw is detachably connected to the outer wall of the trough body, and one end of the foldable screw is in contact with the outer wall of the elastic baffle, and the foldable screw is used to adjust the opening of the discharge port formed by the two elastic baffles.

[0007] As a further implementation method, the foldable screw rod is divided into multiple rod segments that can be folded by 0° to 90°.

[0008] As a further implementation, the contact end between the foldable screw and the elastic baffle is conical.

[0009] As a further implementation, the cross-section of the other end of the foldable screw is rectangular.

[0010] As a further implementation, a plurality of buckles are installed on the outer wall of the tank body, and the foldable screw is clamped in the buckles.

[0011] As a further implementation, one end of the elastic baffle is fixed to the side baffle of the trough body, and the other end is not fixed.

[0012] As a further implementation, a gap is left between the bottom of the elastic baffle and the bottom plate of the trough body.

[0013] As a further implementation, a scale is provided on the outer side of the elastic baffle.

[0014] As a further implementation method, a plurality of material balancing plates are installed in the tank body along the material flow direction.

[0015] As a further implementation method, the material balancing plate is fixed to the bottom plate of the tank body, and the middle height of the material balancing plate is greater than the heights on both sides.

[0016] The beneficial effects of the utility model are as follows:

[0017] The utility model installs foldable screws and elastic baffles on both sides of the trough body. When the material flow fluctuates greatly, the foldable screw can be adjusted to push one end of the elastic baffle to move, thereby reducing or increasing the width of the material flowing through the elastic baffle on the trough body, thereby increasing or decreasing the height of the material at this position, ensuring that the material height remains within a reasonable range, and stabilizing the detection of the moisture meter; the utility model installs a material equalizing plate on the bottom plate of the trough body, which can block the material with a high material level and evenly distribute it to the material with a low material level, ensuring that the material flowing to the elastic baffle area is uniform and consistent, and maintaining the stability of the moisture meter detection.

[0023] It should be noted that the following detailed descriptions are illustrative and intended to provide further explanation of the present invention. Unless otherwise specified, all technical and scientific terms used in the present invention have the same meanings as those commonly understood by those skilled in the art to which the present invention belongs.

[0024] Example 1:

[0025] The conveyed materials (such as tobacco materials) need to be tested for moisture. The moisture meter is generally installed on the upper part of the trough. The height between the moisture meter probe and the material is generally kept within the range of 25 cm ± 10 cm. Therefore, the material height on the vibrating conveyor generally needs to be between 15 cm and 25 cm. When the material flow is unstable, too low a material height will easily expose the bottom plate of the trough, affecting the accuracy of the moisture meter test. When the material height is too high, the moisture meter will also have inaccurate detection.

[0026] Based on this, this embodiment provides a vibrating conveyor with stable material flow and height, such as Figure 1-Figure 3 As shown, it includes a trough body 5, a vibration mechanism, a balancing body 2, a frame 3, a balancing body 2, an elastic baffle 6, a foldable screw 8, etc. A plurality of supporting legs 1 are installed at the bottom of the frame 3, the trough body 5 is arranged above the frame 3, the balancing body 2 is located on the lower side of the frame 3, and the balancing body 2 is connected to the trough body 5 through the vibration mechanism.

[0027] The vibration mechanism includes multiple rocker arms 4, and the rocker arms 4 move synchronously under the driving action of the motor 9. This structure is the same as the prior art, that is, the rocker arms 4 are arranged at an angle, and the middle part of the rocker arms 4 is connected to the frame 3 through a bearing seat; the motor 9 drives the eccentric wheel to rotate, and the eccentric wheel is connected to the balancing body 2 through a transmission shaft to drive the rocker arm 4 to move.

[0028] The bottom of the trough body 5 is a bottom plate 11, three sides of which are closed and connected to the bottom plate 11. Two side plates arranged along the direction of material flow are side baffles 12. A discharge port is set at one end of the trough body 5; after the tobacco material falls into the bottom plate 11 in the trough body 5, the tobacco material is transported to the discharge port under the vibration action of the vibration mechanism.

[0029] The inner wall of each side baffle 12 is connected to the elastic baffle 6, and the elastic baffle 6 is installed close to the material outlet end of the tank body 5. Figure 2 and Figure 3As shown, the elastic baffle 6 has a horizontal section and an inclined section that are connected as one body. The horizontal section is fixedly connected to the side baffle 12 by bolts, and the inclined section is a free end and is not fixed. A foldable screw 8 is provided on the outside of the inclined section of the elastic baffle 6, and the end of the foldable screw 8 is in contact with the outer wall of the elastic baffle 6. Since the elastic baffle 6 itself is elastic, the inclination angle of the inclined section can be changed by the foldable screw 8, that is, the size of the opening (discharge port) formed between the two elastic baffles 6 can be changed.

[0030] The bottom of the elastic baffle 6 is substantially the same height as the side baffle 12 (or slightly lower), and a gap is left between the bottom of the elastic baffle 6 and the trough body 5 to facilitate the movement of the elastic baffle 6. A ruler is set on the outer surface of the elastic baffle 6, and the scale is 0 to 30 cm. The material height can be observed by the ruler.

[0031] The foldable screw 8 is fully threaded and divided into multiple sections that can be folded from 0° to 90°. The length of the foldable sections can be adjusted according to actual requirements, for example, the foldable sections can be set between 2 cm and 3 cm. The foldable screw 8 has a mating section with the trough 5 and a contact section with the elastic baffle 6. The mating section of the foldable screw 8 can be arranged horizontally, that is, parallel to the direction of material flow, and has a rectangular cross-section, which facilitates rotation with a wrench. The end of the contact section with the elastic baffle 6 adopts a conical design to promote the elastic baffle 6 to move telescopically.

[0032] A plurality of buckles 7 are installed on the outside of the side baffle 12 , and the buckles 7 can clamp the foldable screw 8 to facilitate the disassembly of the foldable screw 8 .

[0033] like Figure 2 As shown, a material balancing plate 10 is provided on the bottom plate 11 of the trough body 5, and multiple material balancing plates 10 can be distributed along the direction of material flow; the material balancing plate 10 is higher in the middle and lower on both sides, with a middle height of about 2 cm to 4 cm and a height of about 1 cm on both sides; and the surface in the opposite direction of material flow is a smooth inclined surface with a slope of 30° to 45°.

[0034] In this embodiment, the trough body 5, the elastic baffle 6 and the material-distributing plate 10 are made of stainless steel; of course, in other embodiments, the above components can also be made of other metal materials.

[0035] The working principle of this embodiment is:

[0036] Before conveying the material, the required material width, that is, the minimum distance between the two elastic baffles 6 in the trough body 5, is calculated based on the material flow rate and within a reasonable material height range (15 cm to 25 cm).

[0037] In the static state, pull out the foldable screw 8 from the buckle 7 (this can be done simultaneously on both sides of the trough body 5), and keep the various parts of the foldable screw 8 in a straight line. Use a wrench to turn the foldable screw 8 clockwise. The foldable screw rotates through the nut fixed on the side baffle 13 of the trough body 5 and gradually extends into the interior of the trough body 5, pushing the elastic baffle 6 to move. The bottom plate 11 of the trough body 5 is a flat or corrugated surface. Because there is a small gap between the elastic baffle 6 and the bottom plate 11, the elastic baffle 6 can move on the bottom plate 11. When the distance between the two elastic baffles 6 reaches the design requirement, stop turning the foldable screw 8, fold the foldable screw 8 90°, and push the part of the foldable screw 8 outside the trough body 5 into the buckle 7 to complete the width adjustment between the elastic baffles 6.

[0038] The frame 3 is fixed by the support legs 1 fixed to the ground; before the material flows into the vibrating conveyor, the motor 9 is energized, and the balancing body 2 is driven to swing back and forth through the transmission mechanism. The balancing body 2 drives the trough body 5 to vibrate back and forth through the rocker arm 4 to prepare for the transportation of the material.

[0039] When the vibrating conveyor is working, the incoming materials are often unevenly distributed in clumps. The material distribution plate 10 (multiple clumps can be provided) can distribute more material clumps into fewer material clumps to complete the material distribution work.

[0040] When the material passes through the area between the two elastic baffles 6, the height of the material is observed by comparing the scales on the elastic baffles 6. When the material height is lower than the design value (for example, the design is 20 cm), the foldable screw 8 is rotated clockwise to reduce the distance between the two elastic baffles 6 and increase the material height; if the material height is higher than 25 cm, the foldable screw 8 is rotated counterclockwise to increase the distance between the two elastic baffles 6, reduce the material height, and finally meet the design value requirements; the detection accuracy of the moisture meter is improved through stable and uniform material height.

[0041] The above description is merely a preferred embodiment of the present application and is not intended to limit the present application. Various modifications and variations are possible for those skilled in the art. Any modifications, equivalent substitutions, or improvements made within the spirit and principles of the present application shall be included within the scope of protection of the present application.
