Abstract
Description
Technical Field
[0001] This application belongs to the field of mechanical processing and manufacturing technology, and relates to a special transmission structure for tubular chain machines. Background Technology
[0002] Tubular chain conveyors are continuous conveying equipment for transporting bulk materials such as powders, small granules, and small lumps. They can transport materials horizontally, inclined, and vertically in combination. When the tubular chain conveyor is working, the chain equipped with disc scrapers moves in a closed pipeline. The scrapers push the material forward along the pipeline, making it an energy-saving and environmentally friendly continuous conveying equipment.
[0003] In existing tubular chain conveyors, there is a certain gap between the discs and the tube wall. When conveying mixtures of granules and powders with large differences in specific gravity, it is easy to cause granules to get stuck and powders to separate, resulting in disc jamming, excessive motor load, affecting transportation efficiency and reducing equipment life. Utility Model Content
[0004] This application provides a dedicated transmission structure for tubular chain conveyors, which solves the technical problem in the prior art where a certain gap exists between the disc assembly and the chain tube wall, causing granular material to become stuck and powder material to separate during material transmission, resulting in disc jamming, excessive motor load, reduced transportation efficiency, and reduced equipment life.
[0005] The following technical solution is adopted in this application:
[0006] This application provides a dedicated transmission structure for a tubular chain machine, comprising: a transmission chain composed of link assemblies connected end to end, a disc assembly mounted on the link assemblies; and brush components mounted on the edge of the disc assembly.
[0007] The link assembly and disc assembly are assembled inside the chain tube.
[0008] Optionally, the link assembly consists of two U-shaped links welded end-to-end to form a ring structure.
[0009] Optionally, the chain link assembly has a positioning post at the welding point to fix the disc assembly.
[0010] Optionally, the transmission chain is a detachable split structure, consisting of multiple link components connected end to end in sequence.
[0011] Optionally, the disk assembly 2 is composed of two semi-circular disks, the combined surface of each semi-circular disk is a kind of bevel, and the end faces of the two bevels are provided with two chain holes 10 and mutually symmetrical oblique through holes 6 and positioning grooves 9 that match the positioning post 5, and the two are engaged with each other.
[0012] Optionally, the oblique through hole 6 is formed by two pairs of coarse oblique through holes and fine oblique through holes interlaced on two oblique surfaces. The coarse oblique through holes and fine oblique through holes are located on one side of the two positioning grooves 9, staggered and opposite to each other, and the two are fastened together by fasteners.
[0013] Optionally, the outer circumference of the disk assembly is provided with a plurality of brush countersunk holes evenly distributed around it, and a brush is formed after the brush is installed on the brush countersunk holes.
[0014] Alternatively, the brush can be fixed by one of the following methods: buckling, clamping, thermoforming, or thermosetting.
[0015] Alternatively, the chain tube is made of a wear-resistant metal material, and the corners are smooth curved bends.
[0016] The beneficial effects of this application are:
[0017] 1. This application provides a special transmission structure for a tubular chain conveyor, in which a brush component is provided on the disc assembly. During the material conveying process, the conveyor chain drives the brush to sweep away the powder or stuck particles adhering to the inner wall of the chain tube, ensuring that the inner wall of the chain tube is clean and unobstructed, free of powder or particles. This reduces the risk of disc jamming and excessive motor load, and further achieves the beneficial effects of improving transportation efficiency and extending equipment life.
[0018] 2. This application provides a dedicated transmission structure for a tubular chain conveyor. Its disc assembly is composed of two semi-circular discs on oblique cut surfaces. It features two symmetrical coarse and fine oblique through holes for insertion and fixation. Finally, a fixing component is inserted into the oblique through holes for secure fixation, ensuring a tight fit between the two semi-circular cut surfaces. This oblique through hole design also allows the fixing component to be hidden within countersunk holes, preventing loosening and keeping the disc assembly surface flush, preventing material from getting stuck in gaps. Furthermore, the two semi-circular planes have positioning grooves that match the positioning posts, engaging to fix the disc assembly to the transmission chain, preventing slippage during material transport, reducing wear, and offering a simple structure that is easy to disassemble, clean, and maintain.

[0023] To enable those skilled in the art to better understand the present application, the technical solutions in the embodiments of the present application will be clearly and completely described below with reference to the accompanying drawings. Obviously, the described embodiments are only some embodiments of the present application, and not all embodiments. Based on the embodiments in the present application, all other embodiments obtained by those of ordinary skill in the art without creative effort should fall within the scope of protection of the present application.
[0024] The present application will now be described in further detail with reference to the accompanying drawings:
[0025] like Figure 1 As shown, this application provides a special transmission structure for a tubular chain machine. This structure can transport a mixture of particles and powders with large differences in specific gravity. It includes: a transmission chain 8 composed of chain link assemblies 1 connected end to end, a disc assembly 2 mounted on the chain link assembly 1; a brush component 3 is installed on the edge of the disc assembly 2; the chain link assembly 1 and the disc assembly 2 are assembled inside the chain tube 4.
[0026] In one embodiment, each link assembly 1 can be equipped with a disc assembly 2, or a disc assembly 2 can be installed at intervals of one or more link assemblies 1. The specific configuration can be determined according to actual conditions. Since the volume and mass of the material differ between different intervals, it is sufficient to ensure that the material between the disc assemblies 2 driven by the conveyor chain does not scatter, maintaining a relatively tight and stationary relationship between the material, the conveyor chain, and the disc assembly 2 during movement. Furthermore, in the prior art, the disc assembly or the entire tubular chain conveyor structure does not include a brush component. In this application, during material conveying, the conveyor chain drives a brush along the inner wall of the chain tube to clean away powder or stuck particles adhering to the inner wall, ensuring a clean and unobstructed inner wall free of powder or particles. This reduces the risk of disc jamming and excessive motor load, further improving transportation efficiency and extending equipment life.
[0027] Optionally, the transmission chain 8 is a detachable split structure, consisting of multiple chain link components 1 connected end to end in sequence.
[0028] Optionally, the link assembly 1 is a ring structure formed by welding the end faces of two U-shaped links together.
[0029] Optionally, the welding part of the chain link assembly 1 has a positioning post 5 for fixing the disc assembly 2.
[0030] In one embodiment, multiple U-shaped link end-to-end welded ring structures are interlocked, forming a transmission chain 8 composed of multiple link assemblies 1 connected end-to-end. Therefore, the transmission chain 8 is a detachable, modular structure, facilitating cleaning and maintenance.
[0031] like Figure 2 , Figure 3 As shown, optionally, the disk assembly 2 is composed of two semi-circular disks, the combined surface of each semi-circular disk is a kind of bevel, and the end faces of the two bevels are provided with two chain holes 10 and mutually symmetrical oblique through holes 6 and positioning grooves 9 that match the positioning post 5, and the two are engaged with each other.
[0032] It should be noted that the disc assembly 2 passes through the chain hole 10 via the link assembly 1 and is engaged with the positioning slot 9 by the positioning pin 5, so that the disc assembly 2 is fixed on the link assembly 1.
[0033] Optionally, the oblique through hole 6 is formed by two pairs of coarse oblique through holes and fine oblique through holes interlaced on two oblique surfaces. The coarse oblique through holes and fine oblique through holes are located on one side of the two positioning grooves 9, staggered and opposite to each other, and the two are fastened together by fasteners.
[0034] It should be noted that the fasteners here can be bolts, countersunk rivets, etc., and there are no restrictions. Furthermore, such as... Figure 2 As shown, the disc assembly 2 is composed of two semi-circular discs on two obliquely cut surfaces. It features two mutually symmetrical coarse and fine oblique through holes for insertion and fixation. Finally, a fixing component is inserted into the oblique through holes for secure fixation, ensuring a tight fit between the two semi-circular cut surfaces. This oblique through hole design also allows the fixing component to be hidden within the countersunk hole, preventing loosening and keeping the disc assembly surface flush, preventing material from getting stuck in gaps. Furthermore, the two semi-circular planes have positioning grooves 9 that match the positioning posts 5, which interlock to fix the disc assembly on the conveyor chain, preventing slippage during material transport, reducing wear, and offering a simple structure that is convenient for disassembly, cleaning, and maintenance.
[0035] Optionally, the outer circumference of the disk assembly 2 is provided with a plurality of brush countersunk holes 7 evenly distributed around it, and the brush is formed after the brush is installed on the brush countersunk holes 7.
[0036] Alternatively, the brush can be fixed by one of the following methods: buckling, clamping, thermoforming, or thermosetting.
[0037] In one embodiment, the disc assembly 2 is made of materials such as hard resin or rubber, and the brush is made of either nylon or animal bristles. It should be noted that the material and density of the brush can be set according to actual conditions to ensure that during material conveying, the conveyor chain drives the brush to sweep away powder or stuck particles adhering to the inner wall of the chain tube, ensuring the inner wall of the chain tube is clean, unobstructed, and free of powder or particles. Furthermore, the brush can be fixed by one of the following methods: buckling, clamping, thermoforming, or thermosetting. It is necessary to ensure that the brush can be firmly fixed around the disc assembly 2 and that the brush can make seamless contact with the chain tube 4, but without excessive friction from the inner wall of the chain tube 4.
[0038] Optionally, the chain tube 4 is made of a wear-resistant metal material, and the corners are smooth curved bends.
[0039] Finally, it should be noted that the above embodiments are only used to illustrate the technical solutions of this application and not to limit them. Although this application has been described in detail with reference to the above embodiments, those skilled in the art should understand that modifications or equivalent substitutions can still be made to the specific implementation of this application. Any modifications or equivalent substitutions that do not depart from the spirit and scope of this application should be covered within the protection scope of the claims of this application.
