Technical Field
[0001] The utility model relates to the technical field of material conveying equipment, in particular to a screw conveyor. Background Art
[0002] In the rubber industry, screw conveyors are often used for the conveying and dispersion of small materials, and control algorithms are used to control the feeding amount, so as to ensure the accuracy of small material weighing. However, because there are many types of small materials and some small materials have sticky physical properties, they are easy to adhere to the screw, resulting in a reduction in the screw conveying efficiency or even an inability to convey. Operators can only disassemble the screw for cleaning, and the disassembly and cleaning of the screw take a lot of time, resulting in a reduction in production efficiency.
[0003] Therefore, how to achieve self-cleaning of the screw is a technical problem that those skilled in the art need to solve at present. Summary of the Utility Model
[0004] In view of this, the purpose of the utility model is to provide a screw conveyor to achieve self-cleaning of the screw.
[0005] To achieve the above purpose, the utility model provides the following technical solutions:
[0006] A screw conveyor includes a conveyor body, a first feeding trough, a first screw and a cleaning rod. The first feeding trough is arranged inside the conveyor body for conveying materials. The first screw is arranged inside the first feeding trough and can rotate around its own axis.

[0023] Next, the technical solutions in the embodiments of the present utility model will be clearly and completely described in conjunction with the accompanying drawings in the embodiments of the present utility model. Obviously, the described embodiments are only a part of the embodiments of the present utility model, rather than all the embodiments. Based on the embodiments in the present utility model, all other embodiments obtained by those of ordinary skill in the art without making creative efforts belong to the protection scope of the present utility model.
[0024] In the description of the present utility model, it should be understood that the orientation or positional relationship indicated by the terms "upper", "lower", "top surface", "bottom surface", etc. is based on the orientation or positional relationship shown in the accompanying drawings, and is only for the convenience of describing the present utility model and simplifying the description, rather than indicating or implying that the indicated position or element must have a specific orientation, be constructed and operated in a specific orientation, and therefore should not be construed as a limitation of the present utility model. In addition, the terms "first" and "second" are only used for descriptive purposes and cannot be construed as indicating or implying relative importance.
[0025] As Figures 1 - 3 shown, the screw conveyor disclosed in the present utility model includes a conveyor body 100, a first material conveying trough 200, a first screw 201, and a cleaning rod 300. The first material conveying trough 200 is arranged inside the conveyor body 100 for conveying materials. The first screw 201 is arranged inside the first material conveying trough 200 and can rotate around its own axis. The first end of the cleaning rod 300 is fixedly connected to the first material conveying trough 200, and its second end is arranged close to the first screw 201. Specifically, bearings are arranged at both ends of the first screw 201 and are connected to the conveyor body 100. The conveyor body 100 includes a driving device for driving the first screw 201 to rotate around its own axis. Specifically, the cleaning rod 300 is a round rod with a smooth outer surface to prevent materials from adhering to the outer wall of the cleaning rod 300. When the screw conveyor provided by the present utility model is in use, materials are arranged inside the first material conveying trough 200, the first screw 201 rotates around its own axis, so that the materials move along the first material conveying trough 200. At the same time, the cleaning rod 300 remains stationary, and the second end of the cleaning rod 300 scrapes off the materials adhering to the first screw 201, thereby realizing self-cleaning of the screw without disassembling the screw. While reducing the materials adhering to the first screw 201, the material conveying efficiency of the screw conveyor is improved.
[0026] To optimize the above technical solution, the screw conveyor further includes a mounting seat 400. The mounting seat 400 is fixedly connected to the outer wall of the first material conveying trough 200, and the first end of the first screw 201 cleaning rod 300 is connected to the mounting seat 400. Specifically, the mounting seat 400 is installed on the outer wall of the first material conveying trough 200 by screws or is welded to the outer wall of the first material conveying trough 200. During use, when the first end of the cleaning rod 300 is connected to the mounting seat 400, the extending direction of the cleaning rod 300 is perpendicular to the axial direction of the first screw 201, so as to directly point to the outer wall of the first screw 201. Thus, when the first screw 201 rotates, the materials adhered to the first screw 201 can be scraped off.
[0027] To optimize the above technical solution, the mounting seat 400 is provided with a threaded hole, and the first end of the cleaning rod 300 first screw 201 is threadedly connected to the mounting seat 400. Specifically, the threaded hole on the mounting seat 400 can be a through hole or a non-through hole, and the first end of the cleaning rod 300 is provided with an external thread. During use, when the first end of the cleaning rod 300 is threadedly connected to the threaded hole, the operator can adjust the distance between the second end of the cleaning rod 300 and the first screw 201 by controlling the screwing-in length of the first end of the cleaning rod 300, so as to meet various use requirements and improve the use flexibility of the screw conveyor. Further, the threaded connection between the mounting seat 400 and the cleaning rod 300 can play a sealing role to prevent materials from leaking from the connection between the cleaning rod 300 and the mounting seat 400, thereby improving the sealing effect of the first conveying trough.
[0028] To optimize the above technical solution, the first screw 201 is provided with a first blade 202, and the first blade 202 is provided with a notch 203 for avoiding the cleaning rod 300 first screw 201. Specifically, the number of the first blades 202 is multiple, and they are spiral blades. During use, when the first screw 201 rotates, interference may occur between the cleaning rod and the first blade 202. By arranging the notch 203 on the first blade 202, interference between the cleaning rod and the first blade 202 can be avoided, so as to ensure the stable operation of the first screw 201, and while ensuring the operation stability of the screw conveyor, meet the self-cleaning requirement of the first screw 201.
[0029] To optimize the above technical solution, the screw conveyor further includes a second material conveying trough 500 and a second screw 501. The second screw 501 is arranged inside the second material conveying trough 500, and the second screw 501 is arranged in parallel with the first screw 201. Specifically, the screw conveyor may include one or more material conveying troughs at the same time. Specifically, the diameter of the first material conveying trough 200 is larger than that of the second material conveying trough 500. When there is more material to be conveyed or the metering accuracy is higher, the operator can select the first material conveying trough 200. When there is less material to be conveyed or the metering accuracy is lower, the operator can select the second material conveying trough 500. Such an arrangement can improve the flexibility of use of the screw conveyor and further meet various use requirements.
[0030] To optimize the above technical solution, a second blade 502 is arranged on the second screw 501, and the number of the second blades 502 is larger than that of the first blades 202. Specifically, on the premise that the lengths of the first screw 201 and the second screw 501 are the same, the number of the second blades 502 is larger than that of the first blades 202, that is, the arrangement density of the second blades 502 on the second screw 501 is larger, which can make the number of materials discharged at one time smaller under the action of the second blades 502 in the same time, thereby reducing the error of the material discharge value and meeting the requirements of a smaller metering accuracy. Such an arrangement enables the second conveying trough to meet the self-cleaning of the second screw 501 during the material conveying process under a smaller metering accuracy, thereby expanding the application range of the screw conveyor.
[0031] To optimize the above technical solution, the number of the cleaning rods 300 is less than or equal to the number of the first blades 202. Specifically, material accumulation and adhesion are not likely to occur at the feeding end of the first conveying trough, and fewer or no cleaning rods 300 may be provided, so as to streamline the structure of the screw conveyor and improve its structural strength. Further, the plurality of cleaning rods 300 may be evenly arranged on the first screw 201 to improve the cleaning effect on the first screw 201. It should be noted that the internal structure of the second conveying trough is the same as that of the first conveying trough, and only the distribution density of the second blades 502 is different, so that the second conveying trough can also achieve self-cleaning.
[0032] To optimize the above technical solution, the distance between the second end of the cleaning rod 300 and the first screw 201 is 1 mm to 2 mm. Specifically, the purpose of keeping a small distance between the second end of the cleaning rod 300 and the outer wall of the first screw 201 is, on the one hand, to prevent friction between the second end of the cleaning rod 300 and the outer wall of the first screw 201, which may affect the service life of the cleaning rod 300, and on the other hand, to ensure that the distance between the second end of the cleaning rod 300 and the outer wall of the first screw 201 is small enough so that the cleaning rod 300 can push aside the materials attached to the outer wall of the first screw 201, thereby achieving the optimal cleaning effect on the first screw 201. If the distance between the second end of the cleaning rod 300 and the first screw 201 is other values, the cleaning of the first screw 201 can also be achieved, but too large a distance will affect the cleaning effect, which will not be elaborated here.
[0033] To optimize the above technical solution, the screw conveyor further includes a sealing ring, which is connected to the cleaning rod and used to seal the threaded hole. Specifically, the sealing ring is installed on the cleaning rod 300, buckled on the outer wall of the first conveying trough through the mounting seat 400, and fixed by screws to further seal the connection position between the mounting seat 400 and the cleaning rod, ensuring the sealing effect on the first conveying trough.
[0034] To optimize the above technical solution, the screw conveyor further includes a blowing joint. The inside of the cleaning rod 300 is hollow, and through holes are arranged on the side wall of the cleaning rod 300. The blowing joint is connected to the first end of the cleaning rod 300 and used to introduce gas into the inside of the cleaning rod 300. Specifically, the blowing joint is connected to an air pipe, which is used to transport gas. Specifically, the threaded hole is a through hole. The cleaning rod 300 passes through the threaded hole, its first end is threadedly connected to the blowing joint, and the second end extends into the first conveying trough. During use, the blowing joint fills the inside of the cleaning rod 300 with gas, and gas can be introduced into the cleaning rod 300 on the basis of material pushing and sweeping, so as to disperse the material powder inside the first conveying trough 200 through the air flow, enhancing the cleaning effect and effectively preventing material accumulation and adhesion.
[0035] It should be noted that the first screw 201 and the second screw 501 can be horizontal conveying screws or vertical conveying screws, that is, the screw conveyor can be a horizontal conveyor or a vertical conveyor, both of which can achieve self-cleaning of the screw and improve the conveying efficiency of materials.
[0036] The advantages of the present utility model are as follows:
[0037] (1) Self-cleaning of the screw is achieved;
[0038] (2) The conveying efficiency of materials is improved;
[0039] (3) High flexibility in use and strong practicability.
[0040] It should be noted that the screw conveyor provided by the present utility model can be used in the technical field of material conveying equipment or other fields. The other fields refer to any fields other than the technical field of material conveying equipment. The above is only an example and does not limit the application fields of the screw conveyor provided by the present utility model.
