[0031] The screw conveyor is a machine that uses a motor to drive the screw to rotate and push materials to achieve the purpose of conveying. At present, the screw conveyor is widely used in various industrial fields, such as building materials, chemicals, electricity, metallurgy, coal, grain and other industries. However, when the screw conveyor conveys sticky or easily adhered materials, the materials are easy to adhere to the inner wall of the conveyor during the conveying process, causing blockage, jamming and other phenomena, affecting the normal operation of the conveying equipment.

[0032] In view of this, the utility model provides a screw conveying device, which aims to solve the problem that materials are easily adhered to the inner wall of the conveying device during conveying. Figure 1 to Figure 2 This is a schematic structural diagram of the screw conveying device provided by the utility model.

[0033] See also Figure 1 to Figure 2The screw conveying device 100 includes a shell 1 and a vibration structure 2. The vibration structure 2 is fixedly installed on the shell 1 to form vibration along the axial direction of the shell 1 to drive the shell 1 to reciprocate along its axial direction.

[0034] In the technical solution of the utility model, the shell 1 is connected to other structures through a flexible connection structure 3 to isolate the screw conveying device 100 from other equipment to prevent the vibration of the shell 1 from being transmitted to other equipment. The vibration structure 2 is fixedly installed on the shell 1 to form a vibration along the axial direction of the shell 1 to drive the shell 1 to delay the axial reciprocating vibration, which not only helps to loosen the material adhered to the shell 1 and reduce the probability of the material adhering to the shell 1, but also helps to assist the material to move along the axial direction of the shell 1 to prevent the material from blocking the shell 1, thereby solving the problem that the material is easily adhered to the inner wall of the conveying device during the screw conveying device 100 conveying.

[0035] It should be noted that the shell 1 has various shapes, such as a straight line or a U-shape, etc., and the present invention does not limit this.

[0036] Furthermore, there are multiple types of the vibration structure 2. The vibration structure 2 can be an acoustic excitation structure or a magnetic excitation structure, etc. The utility model does not limit this. Specifically, in this embodiment, the vibration structure 2 includes a magnetic attraction portion 21 and a matching portion 22 arranged at intervals along the axial direction of the shell 1. The magnetic attraction portion 21 and the matching portion 22 are magnetically matched with each other so that the shell 1 can vibrate reciprocatingly along its axial direction. In this way, by setting the magnetic attraction portion 21 and the matching portion 22 that vibrate with magnetic attraction, the vibration structure 2 can generate vibration along the axial direction of the shell 1 to drive the shell 1 to vibrate along its axial direction.

[0037] In this embodiment, the spacing between the magnetic attraction portion 21 and the matching portion 22 is L, wherein 4mm≤L≤6mm. Since the vibration structure 2 is vibrated by the magnetic attraction and matching between the magnetic attraction portion 21 and the matching portion 22, if the spacing between the magnetic attraction portion 21 and the matching portion 22 is too small, the magnetic attraction portion 21 may collide with the matching portion 22, which is easy to generate noise. On the contrary, if the spacing is too large, it will affect the magnetic attraction effect of the magnetic attraction portion 21, and then affect the vibration effect of the vibration structure 2. Therefore, 4mm≤L≤6mm can ensure the magnetic attraction effect of the magnetic attraction portion 21 so that the vibration structure 2 can generate vibration along the axial direction of the shell 1, and can avoid the collision between the magnetic attraction portion 21 and the matching portion 22 to avoid noise. It can be understood that the spacing L between the magnetic attraction portion 21 and the matching portion 22 can be 4.5mm, 5mm or 5.5mm, and of course it can also be any value in the above range, and the utility model is not limited to this.

[0038] There are many ways to form the shell 1. The shell 1 can be integrally formed or assembled, and the utility model does not limit this. Specifically, in this embodiment, the shell 1 includes two shell segments 11 arranged at intervals along the axial direction of the shell 1, and the screw conveying device 100 also includes a connecting structure 3 arranged between the two shell segments 11 to connect the two shell segments 11. In this way, by setting the connecting structure 3, the two shell segments 11 are assembled to form the shell 1, so as to reduce the length of the shell 1 and facilitate transportation.

[0039] In some embodiments of the utility model, the connecting structure 3 includes two connecting flanges 31 and connecting screws 32. The two connecting flanges 31 are respectively fixed on the two shell segments 11, and the connecting screws 32 are passed through the two connecting flanges 31 to connect the two shell segments 11. In this way, by setting the two connecting flanges 31, the contact area of ​​the two shell segments 11 is expanded to facilitate the connection of the connecting structure 3. At the same time, by setting the connecting screws 32, the two shell segments 11 can be detachably connected together to facilitate the loading and unloading of the shell segments 11, which is convenient for subsequent maintenance or replacement.

[0040] It can be understood that there are many ways to connect the connecting flange 31 to the shell segment 11. The connecting flange 31 can be installed on the shell segment 11 by welding or by screws, etc. The utility model does not limit this. Specifically, in this embodiment, the connecting flange 31 and the shell segment 11 are connected by welding to connect the connecting flange 31 to the shell segment 11, which helps to improve the connection strength between the connecting flange 31 and the shell segment 11 and improve the sealing between the connecting flange 31 and the shell segment 11.

[0041] In some embodiments of the utility model, the connecting structure 3 also includes an elastic sealing sleeve 4 arranged between the two connecting flanges 31, for sealing the gap between the two shell segments 11. In this way, by setting the elastic sealing sleeve 4, the gap between the two shell segments 11 is sealed to form a closed cavity with the shell 1 that can be used to convey materials.

[0042] It should be noted that there are many ways to set up the vibration structure 2. The vibration structure 2 can be set simultaneously in one of the shell segments 11, or can be set between two of the shell segments 11. The utility model does not limit this. Specifically, in this embodiment, the magnetic attraction part 21 and the matching part 22 are respectively arranged on the two shell segments 11. In this way, by replacing the elastic sealing sleeve 4 of different specifications, the gap between the two shell segments 11 can be adjusted, and then the distance between the magnetic attraction part 21 and the matching part 22 can be adjusted.

[0043] In some embodiments of the utility model, the shell 1 is provided with a feed port 12, and the feed port 12 and the vibration structure 2 are respectively arranged on both sides of the shell 1. Since the feed port 12 is usually arranged at an angle with the material conveying direction of the screw conveying device 100, the material is easily accumulated at the feed port 12, causing the feed port 12 to be blocked. Therefore, the vibration device is arranged on the side of the shell 1 away from the feed port 12 to prevent the vibration structure 2 from interfering with the feed port 12, so that the vibration device can be as close to the feed port 12 as possible to prevent the feed port 12 from being blocked.

[0044] In some embodiments of the utility model, the shell 1 is provided with a discharge port 13, and the discharge port 13 and the vibration structure 2 are respectively arranged on both sides of the shell 1. Since the discharge port 13 is usually arranged at an angle with the material conveying direction of the spiral conveying device 100, the material is easily accumulated at the discharge port 13, causing the discharge port 13 to be blocked. Therefore, the vibration device is arranged on the side of the shell 1 away from the discharge port 13 to prevent the vibration structure 2 from interfering with the discharge port 13, so that the vibration device can be as close to the discharge port 13 as possible to prevent the discharge port 13 from being blocked.

[0045] It should be noted that the above two related technical features: "the feed port 12 and the vibration structure 2 are respectively arranged on both sides of the shell 1", and "the discharge port 13 and the vibration structure 2 are respectively arranged on both sides of the shell 1" can be set one by one or at the same time, and the present utility model does not limit this.

[0046] In some embodiments of the utility model, the shell 1 is provided with a feed port 12 and a discharge port 13, and two vibration structures 2 are provided, and the two vibration structures 2 are provided corresponding to the discharge port 13 and the feed port 12 respectively. Since the feed port 12 and the discharge port 13 are usually provided at an angle with the material conveying direction of the screw conveying device 100, the material is easily accumulated at the feed port 12 and the discharge port 13, resulting in blockage of the feed port 12 and the discharge port 13. Therefore, two vibration structures 2 are provided to guide the material flowing out of the feed port 12 and the discharge port 13 to prevent the material from accumulating at the feed port 12 and the discharge port 13.

[0047] In some embodiments of the utility model, the screw conveying device 100 also includes a rotating shaft 5 and a blade 6 arranged on the rotating shaft 5, and the periphery of the blade 6 is provided with an opening 61 extending radially thereof. In this way, the rotating shaft 5 is provided to drive the blade 6 to rotate, and the blade 6 is provided to push the material to move along the axial direction of the shell 1. At the same time, the opening 61 is provided to destroy the adhesion between the blade 6 and the material, so that the vibration structure 2 can easily loosen the material adhered to the blade 6 and prevent the material from adhering to the blade 6.

[0048] It is understandable that the opening 61 may have a variety of shapes, for example, a triangle, a U-shape, a rectangle, etc., and the present invention does not limit this.

[0049] Furthermore, the number of openings 61 on the blade 6 may be one or more, and the present invention does not limit this. Specifically, in the present embodiment, a plurality of openings 61 are provided, and the plurality of openings 61 are provided at circumferential intervals along the blade 6. Thus, by providing a plurality of openings 61, the adhesion force between the blade 6 and the material can be further reduced, so that the vibration structure 2 can easily vibrate off the material on the blade 6.

[0050] The above description is only a preferred embodiment of the present invention, and does not limit the patent scope of the present invention. All equivalent structural changes made under the concept of the present invention using the contents of the specification and drawings of the present invention, or direct / indirect application in other related technical fields are included in the patent protection scope of the present invention.
