Description

Technical Field

[0001] The utility model relates to the field of screw conveyors, in particular to a rotary support device for a screw conveyor. Background Art

[0002] The screw conveyor uses the spiral blades on the rotating shaft to push the material forward to realize the transportation of materials, especially powdered materials. However, when the length of the screw conveyor is long, the overall stability of the rotating shaft will be obviously insufficient, affecting the smoothness and accuracy of the transportation. Therefore, a support structure will be added in the middle of the rotating shaft to improve the stability of the rotating shaft rotation. The existing rotating support structure is prone to shaking after long-term use, resulting in increased friction between the rotating support structure and the rotating shaft, which seriously reduces the overall service life and requires frequent disassembly and replacement. However, disassembly and replacement are very difficult. Therefore, how to provide long-term and stable support for the rotating shaft is a technical problem that urgently needs to be solved on the existing longer screw conveyors. Utility Model Content

[0004] In order to achieve the above-mentioned purpose, the present invention is realized through the following technical solutions:

[0005] A rotating support device for a screw conveyor comprises a bracket arranged between a front barrel and a rear barrel, wherein the front barrel and the rear barrel are both rotatably connected to a rotating shaft, the rotating shaft is provided with a spiral blade, the front barrel and the rear barrel are symmetrically provided with a plurality of slots on opposite sides, the top of the bracket is symmetrically provided with a plurality of plug-ins movably plugged into the slots on both sides, the bracket is provided with a material passing hole, the bottom of the bracket is rotatably connected to a connecting shaft, and the two ends of the connecting shaft are respectively connected to the rotating shafts in the front barrel and the rear barrel.

[0006] Furthermore, a plurality of fixing seats are provided on the inner walls of the front barrel and the rear barrel on opposite sides, and the slots are provided on the fixing seats.

[0007] Furthermore, a fixing plate is provided on the top of the bracket, the thickness of the fixing plate is lower than the thickness of the bracket, and the inserts are symmetrically arranged on both sides of the fixing plate.

[0008] Furthermore, both sides of the fixing plate are in contact with the fixing seats on both sides respectively, and the top of the bracket is in contact with the bottoms of the plurality of fixing seats.

[0009] Furthermore, the longitudinal section of the feed hole is fan-shaped.

[0010] Furthermore, the front barrel and the rear barrel, and the rotating shaft and the connecting shaft are connected via flanges.

[0021] The present invention will be further described below with reference to specific embodiments. It should be understood that these embodiments are intended only to illustrate the present invention and are not intended to limit the scope of the present invention. Furthermore, it should be understood that after reading the contents of this invention, those skilled in the art may make various changes or modifications to the present invention, and that these equivalent forms also fall within the scope defined in this application.

[0022] Reference Figure 1 and Figure 2 The present invention relates to a rotary support device for a screw conveyor. The main structure includes a bracket 3 arranged between the front barrel 1 and the rear barrel 2. Due to the long length of the screw conveyor, its barrel adopts the combination connection of the front barrel 1 and the rear barrel 2, and an additional supporting structure is arranged at the connection position. The bracket 3 is the main part of the supporting structure. The front barrel 1 and the rear barrel 2 are both rotatably connected to the rotating shaft 4 through bearings. The rotating shaft 4 at one end is driven to rotate by a motor. The rotating shaft 4 is provided with a spiral blade, which is driven by the rotating shaft 4 to rotate, and the materials in the front barrel 1 and the rear barrel 2 are pushed forward to realize the transportation of the materials. The opposite sides of the front barrel 1 and the rear barrel 2 are symmetrically provided with a plurality of slots 5. The slots 5 are arranged on the end portions of the front barrel 1 and the rear barrel 2 that are close to each other. Both sides of the top of the bracket 3 are symmetrically fixed with a plurality of plug-in blocks 6 that are movably plugged into the slots 5 by welding or bolts. In this structure, when the front barrel 1 and the rear barrel 2 are connected and fixed by bolts, the slots 5 and The insert block 6 at the top of the bracket 3 is fixedly connected, thereby effectively fixing the position of the bracket 3. Therefore, as long as the connection between the front barrel 1 and the rear barrel 2 is strong enough, the bracket 3 will not shake, which greatly simplifies the fixing steps of the bracket 3, improves the firmness of the bracket 3 structure, and reduces the difficulty of subsequent maintenance and replacement. The bracket 3 is provided with a through-feed hole 7, so that the material will pass through the through-feed hole 7 when flowing through here, reducing the resistance to material transportation, and correspondingly reducing the extrusion deformation that the material may cause to the bracket 3, further improving the stability of the bracket 3 structure. The bottom of the bracket 3 is rotatably connected to the connecting shaft 8 through a bearing, and the two ends of the connecting shaft 8 are respectively connected to the rotating shaft 4 in the front barrel 1 and the rear barrel 2. The bracket 3 supports the connecting shaft 8, so that the rotating shaft 4 connected to the two ends of the connecting shaft 8 is more stable during the rotation process, thereby improving the support effect of the longer screw conveyor shaft 4, avoiding possible wear and consumption, and improving the overall service life and stability of the support structure.

[0023] Preferably, refer to Figure 3 and Figure 5, a plurality of fixing seats 9 are fixed on the inner walls of the opposite sides of the front barrel 1 and the rear barrel 2 by welding or bolts, and the slots 5 are arranged on the opposite side of the fixing seats 9. Such a structure makes it possible for the two slots 5 to be relatively close to the plug-in block 6 and fixed thereto after the front barrel 1 and the rear barrel 2 are assembled and connected, and at the same time, the connection between the plug-in block 6 and the slot 5 is blocked, thereby preventing the material from entering the connection when passing through, so that the connection is not easily corroded and damaged, thereby ensuring the firmness of the connection between the plug-in block 6 and the slot 5, reducing the chance of shaking of the bracket 3 in the later stage, and improving the stability of the support structure of the bracket 3.

[0024] Preferably, a fixing plate 10 is fixed to the top of the bracket 3 by welding or integral molding, and the thickness of the fixing plate 10 is lower than the thickness of the bracket 3. The insert block 6 is symmetrically fixed on both sides of the fixing plate 10 by welding or integral molding. Such a structure allows the insert block 6 to be fixed on the fixing plate 10 with lower thickness at the top of the bracket 3, thereby shortening the overall thickness of the bracket 3. As a result, the support structure reduces the length of the missing part of the spiral blade while ensuring the support strength, avoiding the possibility of material accumulation and blockage here, and ensuring the smoothness of material transportation.

[0025] Preferably, both sides of the fixing plate 10 are in contact with the fixing seats 9 on both sides respectively, and the top of the bracket 3 is in contact with the bottoms of multiple fixing seats 9. Such a structure enables the fixing plate 10 to be clamped and fixed by the fixing seats 9 on both sides, and the top of the bracket 3 is in contact with the bottom of the fixing seat 9, so that multiple positions of the entire bracket 3 are effectively restricted and fixed, thereby further avoiding possible tilting and shaking of the bracket 3 and further improving the firmness of the bracket 3 structure.

[0026] Preferably, refer to Figure 4 The longitudinal section of the feed hole 7 is fan-shaped. The fan-shaped structure can ensure that the structural strength of the bracket 3 in the area outside the feed hole 7 remains unchanged while ensuring the maximum material throughput, thereby ensuring the overall structural strength of the bracket 3 and ensuring the firmness and stability of the support at the middle connection of the rotating shaft 4.

[0027] Preferably, the front barrel 1 and the rear barrel 2, and the rotating shaft 4 and the connecting shaft 8 are connected by a flange 11. Such a structure makes the connection between the front barrel 1 and the rear barrel 2 more secure, indirectly ensures the firmness of the position of the bracket 3, and the connection between the two rotating shafts 4 and the connecting shaft 8 is also more stable, and it is not easy to shake or tilt when the rotating shaft 4 is rotating, thereby ensuring the stability of material transportation.

[0028] Working principle: The utility model is provided with a bracket 3 between the front barrel 1 and the rear barrel 2. The bottom of the bracket 3 is rotatably connected with a connecting shaft 8. The two ends of the connecting shaft 8 are respectively connected to the rotating shafts 4 on both sides. A plurality of plug-in blocks 6 are symmetrically provided on both sides of the top of the bracket 3. A plurality of slots 5 are provided on the opposite sides of the front barrel 1 and the rear barrel 2. The plug-in blocks 6 are movably plugged into the slots 5. When the front barrel 1 and the rear barrel 2 are fixed, such a structure can fix the position of the bracket 3 by the cooperation of the slots 5 and the plug-in blocks 6. As long as the connection between the front barrel 1 and the rear barrel 2 is firm enough, then The bracket 3 will not shake, so the bracket 3 provides a more stable support for the connecting shaft 8, which makes the connection between the rotating shaft 4 in the front barrel 1 and the rear barrel 2 more secure, and disassembly and maintenance are also more convenient, which greatly reduces the difficulty of disassembly and replacement; a feed hole 7 is set on the bracket 3. Such a structure allows the material to pass through the feed hole 7 when flowing through the support position, thereby greatly reducing the resistance to material transportation, and at the same time reducing the possible extrusion and bending of the material on the bracket 3, ensuring the stability of the bracket 3 structure, and improving the overall service life of the support structure.
