Technical Field

[0001] This utility model relates to the field of screw conveyor technology, and in particular to a high-efficiency and stable screw conveyor. Background Technology

[0002] A screw conveyor is a machine that uses a motor to drive a screw to rotate and push materials to achieve the purpose of conveying. Screw conveyors can convey horizontally, inclined or vertically, and have the advantages of simple structure, small cross-sectional area and good sealing performance. In terms of conveying form, they are divided into shafted screw conveyors and shaftless screw conveyors. In terms of appearance, they are divided into U-shaped screw conveyors and tubular screw conveyors.

[0003] When using a screw conveyor, the bearings are exposed to the outside, making them susceptible to dust and impurities entering the bearings. This allows material dust to penetrate the bearings, creating an abrasive effect that accelerates wear and damage, thus affecting the bearings' service life.

[0004] To address the aforementioned problems, a highly efficient and stable screw conveyor is proposed. Utility Model Content

[0005] The purpose of this invention is to at least solve one of the technical problems existing in the prior art, and to provide a high-efficiency and stable screw conveyor that can solve the problems in the background art.

[0010] Preferably, a suction housing is rotatably sleeved on the rotating shaft, and an air suction pipe is fixedly installed on one side of the suction housing, with the air suction pipe communicating with the interior of the suction housing.

[0011] Preferably, a suction blade is fixedly installed on the rotating shaft, and the suction blade is located inside the suction housing.

[0012] Preferably, the air outlet end of the suction housing is connected to a connecting pipe, and one end of the connecting pipe is connected to a collection box, which is fixedly connected to the support frame.

[0013] Preferably, a filter screen is provided on one side of the collection box.

[0014] Compared with the prior art, the beneficial effects of this utility model are:

[0015] (1) The efficient and stable screw conveyor allows the gas inside the air cylinder to enter the interior of the connecting hard pipe.

Detailed Implementation

[0024] The technical solutions of the present utility model will be clearly and completely described below with reference to the accompanying drawings of the embodiments. Obviously, the described embodiments are only some embodiments of the present utility model, and not all embodiments. Based on the embodiments of the present utility model, all other embodiments obtained by those of ordinary skill in the art without creative effort are within the protection scope of the present utility model.

[0025] To further understand the content of this utility model, a detailed description of this utility model will be provided in conjunction with the accompanying drawings.

[0026] Please see Figure 1-5 This utility model provides a technical solution: a high-efficiency and stable screw conveyor, including a screw conveyor housing 1, a support frame 11 fixedly installed on one side of the screw conveyor housing 1, a motor 8 fixedly installed on the top of the support frame 11, a rotating shaft 7 fixedly installed at the output end of the motor 8, a bearing 2 fixedly installed on one side of the screw conveyor housing 1, the rotating shaft 7 being disposed inside the bearing 2 and extending into the interior of the screw conveyor housing 1, an air cylinder 12 fixedly installed inside the support frame 11, a connecting rigid pipe 10 connected to the bottom of the air cylinder 12, and an annular gas cylinder fixedly installed at the end of the connecting rigid pipe 10 away from the air cylinder 12. The top of the air cylinder 12 has an air hole 14. A one-way valve 13 is provided on one side of the air cylinder 12. A one-way valve 13 is also provided on one end of the connecting rigid pipe 10 located inside the air cylinder 12. A piston rod 15 is slidably connected inside the air cylinder 12. A piston 19 is fixedly installed on one end of the piston rod 15 located inside the air cylinder 12. The piston 19 is slidably connected inside the air cylinder 12. A tension spring 18 is movably sleeved on the surface of the piston rod 15. The upper end of the tension spring 18 is fixedly connected to the inner wall of the air cylinder 12. The lower end of the tension spring 18 is fixedly connected to the top of the piston 19. A cam 6 is fixedly sleeved on the rotating shaft 7.

[0027] The motor 8 is started, causing the rotating shaft 7 to rotate, which in turn drives the screw conveyor inside the screw conveyor housing 1 to rotate, thereby conveying materials. As the rotating shaft 7 rotates, it drives the cam 6 to rotate. With the continuous rotation of the cam 6, the cam 6 compresses the piston rod 15, causing the piston rod 15 to slide downwards inside the air cylinder 12. This causes the piston 19 to slide inside the air cylinder 12, stretching the tension spring 18. Simultaneously, external gas enters the upper side of the piston 19 through the air hole 14. Since one-way valves 13 are installed on both the connecting rigid pipe 10 and one side of the air cylinder 12, the piston 19... When moving downwards, the piston 19 compresses the gas inside the air cylinder 12, opening the one-way valve 13 inside the connecting rigid tube 10, allowing the gas inside the air cylinder 12 to enter the connecting rigid tube 10. The one-way valve 13 on the air cylinder 12 then closes, allowing the gas to enter the connecting rigid tube 10 and be transported to the annular air nozzle 3. The annular air nozzle 3 then blows air onto the bearing 2, cleaning the dust off the bearing 2. Blowing air can remove dust, debris, and other foreign matter from the bearing 2 and the surrounding environment, reducing the risk of contaminants entering the bearing 2 and helping to extend the bearing's service life.

[0028] As cam 6 continues to rotate, it will stop pressing on piston rod 15, thereby causing piston rod 15 and piston 19 to reset under the tension of tension spring 18, which in turn causes piston 19 to move upward. At this time, the one-way valve 13 inside the connecting rigid pipe 10 closes, which in turn opens the one-way valve 13 on the air cylinder 12, allowing external gas to be drawn into the air cylinder 12 through the one-way valve 13, thus completing the air intake of the air cylinder 12 for the next use.

[0029] A suction housing 4 is rotatably sleeved on the rotating shaft 7. A suction pipe 5 is fixedly installed on one side of the suction housing 4 and communicates with the interior of the suction housing 4. A suction blade 20 is fixedly installed on the rotating shaft 7 and is located inside the suction housing 4. A connecting pipe 16 is connected to the air outlet end of the suction housing 4. A collection box 9 is connected to one end of the connecting pipe 16. The collection box 9 is fixedly connected to the support frame 11 and a filter screen 17 is provided on one side of the collection box 9.

[0030] Since the collection box 9 and the connecting pipe 16 support the suction housing 4, the suction housing 4 does not rotate when the rotating shaft 7 rotates, which causes the suction blades 20 to rotate. This draws external gas into the suction housing 4 through the suction pipe 5, and then discharges it through the connecting pipe 16. The gas then enters the collection box 9, where it is filtered by the filter screen 17 to remove impurities. This process collects and treats the dust, preventing the cleaned dust from re-entering the bearing 2 and improving the dust collection effect. The filter screen 17 is bolted to the collection box 9, allowing for cleaning and replacement of the filter screen 17, and also enabling the collection of dust inside the collection box 9.

[0031] Working principle:

[0032] The motor 8 is started, causing the rotating shaft 7 to rotate, which in turn drives the screw conveyor inside the screw conveyor housing 1 to rotate, thus conveying the material. As the rotating shaft 7 rotates, it drives the cam 6 to rotate. With the continuous rotation of the cam 6, the cam 6 compresses the piston rod 15, causing the piston rod 15 to slide downwards inside the air cylinder 12. This causes the piston 19 to slide inside the air cylinder 12, stretching the tension spring 18. Simultaneously, external gas enters the upper side of the piston 19 through the air hole 14. Since one-way valves 13 are installed on both the connecting rigid pipe 10 and one side of the air cylinder 12, when the piston 19 moves downwards, it compresses the gas inside the air cylinder 12, opening the one-way valve 13 inside the connecting rigid pipe 10. The gas inside the air cylinder 12 enters the connecting rigid tube 10. The one-way valve 13 on the air cylinder 12 closes, and after the gas enters the connecting rigid tube 10, it is transported to the annular air nozzle 3. The annular air nozzle 3 then blows air onto the bearing 2. As the cam 6 continues to rotate, it stops pressing the piston rod 15, and the piston rod 15 and piston 19 are reset by the tension of the tension spring 18. The piston 19 then moves upward. At this time, the one-way valve 13 inside the connecting rigid tube 10 closes, and the one-way valve 13 on the air cylinder 12 opens, allowing external gas to be drawn into the air cylinder 12 through the one-way valve 13, thus completing the air intake of the air cylinder 12 for future use.

[0033] Since the collection box 9 and the connecting pipe 16 support the suction housing 4, the suction housing 4 does not rotate when the rotating shaft 7 rotates, which causes the suction blades 20 to rotate, drawing external gas into the interior of the suction housing 4 through the suction pipe 5, and then discharging it through the connecting pipe 16, and then into the interior of the collection box 9. Impurities in the gas are filtered through the filter screen 17, thereby achieving dust collection and treatment.

[0034] Finally, it should be noted that the above description is only a preferred embodiment of the present utility model and is not intended to limit the present utility model. Although the present utility model has been described in detail with reference to the foregoing embodiments, those skilled in the art can still modify the technical solutions described in the foregoing embodiments or make equivalent substitutions for some of the technical features. Any modifications, equivalent substitutions, improvements, etc., made within the spirit and principles of the present utility model should be included within the protection scope of the present utility model.
