DETAILED DESCRIPTION

[0020] In order to make the purpose, technical solution and advantages of the utility model more clear, the utility model is further described in detail below in conjunction with the accompanying drawings and embodiments. It should be understood that the specific embodiments described here are only used to explain the utility model and are not used to limit the utility model.

[0021] The specific implementation of the present utility model is described in detail below in conjunction with specific embodiments.

[0022] like Figure 1 As shown, a grid dragon shaft with a protective structure provided by an embodiment of the utility model comprises a spiral dragon conveying shell 1, and the interior of the spiral dragon conveying shell 1 is rotatably connected to a spiral dragon shaft 3 through a rolling bearing, a spiral conveying blade 2 is installed on the outside of the spiral dragon shaft 3, a driving motor 6 is installed on the side of the spiral dragon conveying shell 1, and a driving motor output shaft 5 is arranged at one end of the driving motor 6, a dragon trough discharge port is provided on the outside of the spiral dragon conveying shell 1 near the driving motor output shaft 5, and a feeding port is also provided on the outside of the spiral dragon conveying shell 1;

[0023] The above technical features are all mature existing technologies, and are technical solutions that are not difficult for technical personnel in the field to obtain or think of. Technical personnel in the field can make corresponding adjustments and selections based on the above technical solutions.

[0024] An elastic coupling 4 is installed on the end of the spiral dragon shaft 3 close to the drive motor 6 and the end of the drive motor output shaft 5 away from the drive motor 6.

[0025] In one embodiment of the utility model, the elastic coupling is an integrally formed metal elastic body, which is usually cut from a metal round bar, and the commonly used materials are aluminum alloy, stainless steel, and engineering plastics, which are suitable for various deviations and accurate transmission of torque;

[0026] By arranging an elastic coupling 4 between the spiral dragon shaft 3 and the drive motor output shaft 5, when the spiral conveying blades 2 and the spiral dragon shaft 3 perform a long-term material conveying operation, the elastic coupling 4 can provide good buffering and protection between the spiral dragon shaft 3 and the drive motor output shaft 5, thereby preventing the material inside the spiral dragon conveying shell 1 from reaching the dragon trough outlet due to the long-term impact of the material on the connection between the spiral dragon shaft 3 and the drive motor output shaft 5, thereby improving the service life of the grid dragon shaft.

[0027] like Figure 1 and Figure 2As shown, in one embodiment of the present utility model, a cleaning component is arranged inside the spiral dragon conveying housing 1, and is used to scrape and clean the material attached to the surface of the elastic coupling 4;

[0028] Cleaning kit includes:

[0029] The spiral dragon conveying shell 1 is detachably connected to a mounting panel 15, and a plurality of accommodating grooves 10 are provided on the surface of the mounting panel 15. A guide rod 16 is slidably connected to the inside of the accommodating groove 10. The end of the guide rod 16 away from the mounting panel 15 is connected to a connecting block 12, and a plurality of connecting blocks 12 are commonly installed with a scraper plate 13 on the outside. The spring 11 can keep the scraper plate 13 in a state of continuous close contact with the surface of the elastic coupling 4. However, since the scraper plate 13 is not rigidly connected to the elastic coupling 4, the scraper plate 13 will not cause substantial damage to the elastic coupling 4.

[0030] The connecting block 12 and the outer side of the mounting panel 15 are jointly provided with a spring 11. The connecting block 12, the guide rod 16, the spring 11 and the receiving groove 10 are all on the same axis, and the guide rod 16 is sequentially arranged to penetrate the inside of the spring 11 and the receiving groove 10.

[0031] The surface of the scraper plate 13 is in close contact with the surface of the elastic coupling 4 , and the contact area between the scraper plate 13 and the elastic coupling 4 is made of a flexible material.

[0032] In this embodiment, although the elastic coupling 4 is added between the spiral dragon shaft 3 and the drive motor output shaft 5 to effectively prevent the spiral dragon shaft 3 and the drive motor output shaft 5 from being damaged by impact, it is easy for sticky materials to adhere to the outer surface of the elastic coupling 4 during the material transportation process, which leads to incomplete material transportation and requires the staff to frequently clean the elastic coupling 4;

[0033] In order to solve the above technical problems, a scraper plate 13 supported by a spring 11 is arranged inside the spiral dragon conveying shell 1, so that when the elastic coupling 4 rotates, the scraper plate 13 which is in close contact with the outer surface of the elastic coupling 4 can fully scrape off the sticky material attached to the outer surface of the elastic coupling 4, thereby preventing the sticky material from adhering to the outer surface of the elastic coupling 4 during the conveying process of the spiral conveying blades 2. In addition, the cleaning component has a simple structure and does not require human intervention, thereby increasing the excellent performance of the elastic coupling 4 during use.

[0034] Preferably, a fixing threaded hole 9 is provided on the outer side of the spiral dragon conveying housing 1, a fixing threaded groove 14 is provided on the surface of the mounting panel 15, and the fixing threaded hole 9 and the fixing threaded groove 14 are internally engaged with a limiting threaded rod 8, and a twist handle 7 is installed at one end of the limiting threaded rod 8 away from the mounting panel 15, and the surface of the twist handle 7 is provided with anti-slip grooves, so that the staff can conveniently install or disassemble the cleaning component inside the spiral dragon conveying housing 1, so as to clean or replace the scraper plate 13, and the specific disassembly and assembly process is as follows:

[0035] The staff first extends the installation panel 15 into the interior of the spiral dragon conveying shell 1 through the dragon groove outlet, and makes the surface of the installation panel 15 touch the inner wall of the spiral dragon conveying shell 1, and then adjusts the position of the installation panel 15 and the scraper plate 13, so that the fixed thread groove 14 opened on the installation panel 15 can be aligned with the fixed thread hole 9 opened on the surface of the spiral dragon conveying shell 1, and makes the scraper plate 13 close to the surface of the elastic coupling 4 in a vertical posture. Finally, the staff holds the twist handle 7 and turns the limiting threaded rod 8 into the fixed thread hole 9 and the fixed thread groove 14 in turn to fix the installation panel 15 inside the spiral dragon conveying shell 1, thereby completing the installation operation of the cleaning component.

[0036] The above description is only a preferred embodiment of the present invention and is not intended to limit the present invention. Any modifications, equivalent substitutions and improvements made within the spirit and principles of the present invention should be included in the protection scope of the present invention.
