Description

Technical Field

[0001] This utility model relates to the field of telescopic chutes, and more specifically, to a tubular multi-stage telescopic chute. Background Technology

[0002] Telescopic chutes are flexible connection devices that can be used for conveying and unloading bulk materials. By providing a flexible, efficient, and environmentally friendly closed conveying solution, they solve many pain points in the material transfer process and are an ideal choice for improving operational efficiency, improving the working environment, and reducing operating costs.

[0003] In existing technologies, telescopic chutes are divided into bag-type chutes and multi-stage pipe-type chutes. The former relies on the characteristics of the cloth belt itself for telescopic movement, while the latter uses multiple layers of pipes that can be nested together to extend the conveying path and achieve telescopic effects. When using the latter, the inner wall of the sleeve often rubs against the outer sleeve during telescopic movement, and the conveyed material may stick together. If not cleaned, it will be squeezed and deformed by the overlapping of the inner and outer sleeves, increasing the adhesion area and affecting the overall inner wall environment of the pipe. Over time, this will reduce the service life of the pipe. Furthermore, during material transportation, it will also cause a certain degree of mixing of the transported material, affecting the transportation quality. Utility Model Content

[0004] 1. Technical problems to be solved To address the problems existing in the prior art, the purpose of this utility model is to provide a tubular multi-stage telescopic chute. This chute allows for the rotational scraping and cleaning of the inner wall of the outer sleeve by the bottom end of the inner sleeve during the overlapping and stacking of multiple sleeves. This removes adhering materials before crushing. Furthermore, the scraper can vibrate up and down to shake off surface materials, preventing adhesion and improving the overall practicality of the device. This ensures the cleanliness of the pipe's inner wall and extends the overall service life of the device.

[0005] 2. Technical Solution To solve the above problems, the present invention adopts the following technical solution.

[0006] A tubular multi-stage telescopic chute includes a first pipe body, a second pipe body, and a third pipe body that are movably sleeved together, and further includes... Fixed rings are fixedly installed on the outer side of the top end of the first tube and the outer side of the bottom end of the third tube. Spiral magnetic strips with a spiral structure are fixedly installed on the surface of the second and third tubes. Rotating rings are movably sleeved on the bottom ends of the first and second tubes. A cleaning device is rotatably installed on the bottom end of the rotating ring. A vibration component is fixedly connected to the upper end of the rotating ring.

[0007] Furthermore, the cleaning device includes a connecting ring, the upper end of which has an annular groove, and the bottom end of which is fixedly connected to a scraper.

[0008] Furthermore, the number of scraping blades is several, and the outer walls of the several scraping blades are respectively attached to the inner walls of the corresponding second tube and third tube.

[0009] Furthermore, the shape of the annular groove is adapted to the shape of the rotating ring, and a magnetic block is fixedly connected to the outer side of the connecting ring, and the magnetic block and the spiral magnetic strip are magnetically attracted to each other.

[0010] Furthermore, the vibration assembly includes a sleeve, and a T-shaped sleeve rod is movably sleeved inside the sleeve, with a spring fixedly connected between the sleeve and the T-shaped sleeve rod.

[0011] Furthermore, the number of sleeves is several, and the several sleeves are divided into two groups. The top ends of the two groups of sleeves are respectively fixedly connected to the inside of the bottom end of the first tube and the bottom end of the second tube.

[0012] Furthermore, the bottom end of the T-shaped sleeve is fixedly connected to the top end of the rotating ring.

[0013] 3. Beneficial Effects Compared with existing technologies, the advantages of this utility model are: (1) This solution utilizes a cleaning device in conjunction with a spiral magnetic strip to enable the entire chute to quickly rotate and scrape the inner wall of the second pipe body and the inner wall of the third pipe body while the chute body is interlocked and overlapping. This prevents the material adhering to the surface from being crushed and deformed by the pipe body, ensuring the cleanliness of the inner wall of the pipe and effectively extending the service life of the entire device.

[0014] (2) This solution utilizes a rotating ring and a vibration component to vibrate the entire cleaning device. Especially when dealing with highly viscous materials, the resistance enables the cleaning device to have a vibration power source, thereby allowing the scraped blade surface to automatically shake off, preventing the material from sticking to the blade and affecting the overall scraping effect.

[0020] Example: Please see Figure 1-4 A tubular multi-stage telescopic chute, comprising a first pipe body 1, a second pipe body 2, and a third pipe body 3 movably connected to each other, and further comprising: A fixing ring 4 is fixedly installed on the outer side of the top end of the first tube 1 and the outer side of the bottom end of the third tube 3. A spiral magnetic strip 5 with a spiral structure is fixedly installed on the surface of the second tube 2 and the third tube 3. A rotating ring 7 is movably sleeved at the bottom end of the first tube 1 and the second tube 2. A cleaning device 6 is rotatably installed at the bottom end of the rotating ring 7. A vibration component 8 is fixedly connected to the upper end of the rotating ring 7. It should be noted that the inner walls of the first tube 1, the second tube 2, and the third tube 3 in this application are all coated with wear-resistant and corrosion-resistant coatings, so as to prevent the scratches caused by the first tube 1, the second tube 2, and the third tube 3 during multiple expansion and contraction adjustments, improve the overall service life of the device, and prevent surface rust from causing difficulty in movement during expansion and contraction. The cleaning device 6 includes a connecting ring 601, with an annular groove 602 at the upper end of the connecting ring 601. A scraper 603 is fixedly connected to the bottom end of the connecting ring 601. There are several scrapers 603, and the outer walls of the several scrapers 603 are respectively attached to the inner walls of the corresponding second tube 2 and third tube 3. The shape of the annular groove 602 is adapted to the shape of the rotating ring 7. A magnetic block is also fixedly connected to the outer side of the connecting ring 601. The magnetic block and the spiral magnetic strip 5 are magnetically attracted to each other. Specifically, a magnetic block on the outside of the connecting ring 601 is used to adapt to the change of the spiral angle of the spiral magnetic strip 5 so that the connecting ring 601 can rotate while lifting and lowering. Combined with the oblique setting of the scraper 603, it can achieve effective scraping on both the side and the bottom, improving the overall practicality and cleaning effect of the device. The vibration assembly 8 includes a sleeve 801, a T-shaped sleeve rod 803 is movably sleeved inside the sleeve 801, a spring 802 is fixedly connected between the sleeve 801 and the T-shaped sleeve rod 803, and there are several sleeves 801, which are divided into two groups. The top ends of the two groups of sleeves 801 are respectively fixedly connected to the inside of the bottom end of the first tube 1 and the bottom end of the second tube 2. The bottom end of the T-shaped sleeve rod 803 is fixedly connected to the top end of the rotating ring 7. Specifically, a spring 802 is fixedly connected between the sleeve 801 and the T-shaped sleeve 803, so that the spring 802 can achieve the up-and-down vibration effect of the entire cleaning device 6 through its own deformation and reset, thereby shaking off any material that may be stuck on the surface of the scraper 603, ensuring the cleanliness of the blade, and thus ensuring its efficient scraping effect. The working principle of this utility model is as follows: The first tube 1, the second tube 2, and the third tube 3 are connected between the feed inlet and the receiving inlet by a fixing ring 4, and then the material is conveyed. During the process, some material may stick to the inner wall surface of the third tube 3 and the second tube 2 due to its own stickiness. When the three tubes are retracted and overlapped, the connecting ring 601 is rotated by the spiral magnetic attraction effect of the spiral magnetic strip 5, thereby scraping and cleaning the inner wall of the corresponding tubes in both horizontal and vertical directions. Finally, the scraping blade 603 can be actively pressed up to compress the spring 802, and then released to make the scraping blade 603 vibrate up and down to quickly shake off the material on its surface.

[0021] The above description is merely a preferred embodiment of this utility model; however, the protection scope of this utility model is not limited thereto. Any equivalent substitutions or modifications made by those skilled in the art within the technical scope disclosed in this utility model, based on the technical solution and its improved concept, should be included within the protection scope of this utility model.
