[0002] A screw conveyor (also known as a screw conveyor belt or screw conveyor) is a commonly used material handling device, widely applied in industries such as mining, construction, chemical, food, metallurgy, and pharmaceuticals. It conveys powdery, granular, and lumpy materials through a rotating helical blade (usually installed within a closed trough). Due to its simple structure, small footprint, and ease of operation, it has found widespread use in many industries.

[0003] In existing technologies, screw conveyors are only suitable for conveying small pieces of material. For large pieces of material, especially when conveying a mixture of large stones, small stones and sand, the large stones need to be crushed in advance before conveying, which is costly and time-consuming for enterprises. In addition, it is not convenient to uniformly mix the materials during conveying, and further stirring is required after conveying before use. Therefore, a screw conveyor with crushing function is proposed to address the above shortcomings.

[0021] 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. Example 1

[0022] like Figures 1-6 As shown, this utility model provides a technical solution: a screw conveyor with crushing function, including a supporting base plate 1, a supporting column 8, and a feed box 20 located at the top of the conveying trough 9. The feed box 20 has openings on its upper and lower sides for feeding. A connecting plate 21 is fixedly connected to the outer surface of the feed box 20. A second motor 22 is fixedly connected to the inner wall of the connecting plate 21. A first crushing shaft 23 is fixedly connected to the output end of the second motor 22, and the first crushing shaft 23 is rotatably disposed inside the feed box 20. A first crushing roller 24 is fixedly connected to the outer surface of the first crushing shaft 23. A first gear 25 is fixedly connected to the outer surface of the output end of the second motor 22. A second crushing shaft 26 is rotatably connected inside the feed box 20. One end of the second crushing shaft 26 extends out of the feed box and is fixedly connected to a second gear 27. The second gear 27 meshes with the first gear 25. A second crushing roller 28 is fixedly connected to the outer surface of the second crushing shaft 26.

[0023] Furthermore, a support base 2 is fixedly connected to the upper surface of the support base plate 1, a fixing plate 3 is fixedly connected to the top of the support base 2, a fixing ring 4 is fixedly connected to the upper surface of the fixing plate 3, a first motor 5 is fixedly connected inside the fixing ring 4, a connecting shaft 6 is fixedly connected to the output end of the first motor 5, and a first sprocket 7 is fixedly connected to the other end of the connecting shaft 6; a conveying trough 9 is fixedly connected to the upper surface of the support column 8, a fixing block 10 is fixedly connected to one end of the conveying trough 9, an mounting plate 11 is fixedly connected to the outer surface of the fixing block 10, the mounting plate 11 has a bearing inside, a rotating shaft 12 is rotatably connected inside the mounting plate 11, the rotating shaft 12 is located inside the conveying trough 9, a second sprocket 13 is fixedly connected to one end of the rotating shaft 12 located outside the conveying trough 9, a chain 14 is provided between the second sprocket 13 and the first sprocket 7, a conveying roller 15 is fixedly connected to the outer surface of the rotating shaft 12, a spiral blade 16 is fixedly connected to the outer surface of the conveying roller 15, and multiple stirring rods 17 are fixedly connected to the outer surface of one end of the conveying roller 15 near the discharge port.

[0024] In this embodiment, the material is placed into the feed box 20, and the second motor 22 is started. The output end of the second motor 22 drives the first crushing shaft 23 and the first gear 25 to rotate together. At the same time, the first gear 25 drives the second gear 27 to rotate, causing the second crushing shaft 26 inside the feed box 20 to rotate. That is, the first crushing shaft 23 and the second crushing shaft 26 simultaneously drive the first crushing roller 24 and the second crushing roller 28 to rotate in opposite directions, crushing the material inside the feed box 20. The crushed material enters the interior of the conveying trough 9. At the same time, the first motor 5 is started, and the output end of the first motor 5 drives the connecting shaft 6 to rotate. The connecting shaft 6 drives the first sprocket 7 to rotate, which in turn drives the second sprocket 13 to rotate, thereby driving the rotating shaft 12 to rotate, which in turn drives the conveying roller 15 and the spiral blade 16 to rotate. The rotation of the spiral blade 16 can drive the material to be conveyed. The conveying roller 15 drives multiple stirring rods 17 to rotate, and the stirring rods 17 further stir the material inside the conveying trough 9 evenly. Example 2

[0025] like Figures 1-6 As shown, a balance plate 18 is fixedly connected to the outer surface of the support column 8. The function of the balance plate 18 is to maintain the overall balance of the conveying trough 9 and prevent shaking. A limit plate 19 is fixedly connected to the other end of the conveying trough 9. The limit plate has a bearing inside, and the interior of the limit plate 19 is rotatably connected to the other end of the rotating shaft 12. That is, the two ends of the rotating shaft 12 are rotatably arranged inside the conveying trough through the bearings in the mounting plate and the limit plate.

[0026] Furthermore, the conveying roller 15 and the spiral blade 16 are rotatably connected to the inside of the conveying trough 9 via the rotating shaft 12, conveying the material inside the conveying trough 9 to the end away from the second sprocket 13.

[0027] In this embodiment, a support base 2 is fixed by a support base plate 1, a fixing plate 3 is fixed by the support base 2, and a fixing ring 4 is fixed by the fixing plate 3. Since the support base 2 is relatively short, the fixing ring 4 is needed to ensure the stability of the first motor 5 during operation. A support column 8 supports the conveying trough 9, which is an integral structure. The fixing block 10 is used to install the mounting plate 11 on the outside. The mounting plate 11 stabilizes the rotation of the rotating shaft 12. A balance plate 18 balances the support column 8 as a whole. The support column 8 is a column type and may wobble during the operation of the conveying trough 9. The addition of the balance plate 18 increases the overall area of ​​the support column, thereby increasing stability. A limiting plate 19 stabilizes the rotation of the other end of the rotating shaft 12. The limiting plate 19 is installed on the outside of the other end of the conveying trough 9 to stabilize the rotation of the rotating shaft 12. The inside of the conveying trough 9 alone cannot guarantee the stability of the rotating shaft 12.

[0028] The working principle of this embodiment is as follows: First, the material is placed into the feed box 20, and the second motor 22 is started. The output end of the second motor 22 drives the first crushing shaft 23 and the first gear 25 to rotate together. At the same time, the first gear 25 drives the second gear 27 to rotate, causing the second crushing shaft 26 inside the feed box 20 to rotate. That is, the first crushing shaft 23 and the second crushing shaft 26 simultaneously drive the first crushing roller 24 and the second crushing roller 28 to rotate in opposite directions. The material is drawn into the crushing chamber formed by the two crushing rollers and crushed. The crushed material enters the interior of the conveying trough 9. The first motor 5 is also started at the same time. The output of motor 5 drives the connecting shaft 6 to rotate, which in turn drives the first sprocket 7 to rotate. The first sprocket 7 drives the second sprocket 13 to rotate, which in turn drives the rotating shaft 12 to rotate. The rotating shaft 12 then drives the conveying roller 15 and the spiral blade 16 to rotate. The rotation of the spiral blade 16 can transport materials. The conveying roller 15 drives multiple stirring rods 17 to rotate. The stirring rods 17 are set at the front end of the discharge to mix the internal materials more thoroughly. Since the material is dry, the stirring rods 17 mix the materials inside the conveying trough 9 relatively evenly, which is convenient for later use. The support base 2 is fixed by the support base plate 1, the fixing plate 3 is fixed by the support base 2, and the fixing ring 4 is fixed by the fixing plate 3. Since the support base 2 is relatively short, the fixing ring 4 is needed to ensure the stability of the first motor 5 during operation. The conveying trough 9 is supported by the support column 8. The conveying trough 9 is an integral structure. The function of the fixing block 10 is to install the mounting plate 11 on the outside. The mounting plate 11 stabilizes the rotation of the rotating shaft 12. The balance plate 18 balances the support column 8 as a whole. The support column 8 is a column type, which is prone to shaking when the conveying trough 9 is running. The addition of the balance plate 18 can increase the overall area of ​​the support column, thereby increasing stability. The other end of the rotating shaft 12 is stabilized by the limiting plate 19. The limiting plate 19 is installed on the outside of the other end of the conveying trough 9 to stabilize the rotation of the rotating shaft 12. The inside of the conveying trough 9 alone cannot guarantee the stability of the rotating shaft 12.

Any person skilled in the art may make changes or modifications to the above-disclosed technical content to create equivalent embodiments for application in other fields. However, any simple modifications, equivalent changes, and modifications made to the above embodiments based on the technical essence of the present utility model without departing from the technical solution of the present utility model shall still fall within the protection scope of the technical solution of the present utility model.
