Specifically, the first motor drives the spiral blades to rotate, conveying materials along the conveying pipeline. Screw conveyors can convey materials horizontally, inclined, or vertically, and offer advantages such as a simple structure, small cross-sectional area, excellent sealing, easy operation, simple maintenance, and convenient closed transportation. The design and speed of the spiral blades directly impact the conveyor's efficiency and stability.
[0004] Although screw conveyors have certain advantages in material transportation, when transporting large amounts of materials or transporting materials with certain viscosity or easy to agglomerate, blockage is likely to occur in the conveying pipeline, resulting in reduced conveying efficiency and even affecting production progress.

[0023] The following will be combined with the embodiments of the present invention to clearly and completely describe the technical solutions in the embodiments of the present invention. Obviously, the embodiments described are only part of the embodiments of the present invention, not all of the embodiments. Based on the embodiments of the present invention, all other embodiments obtained by ordinary technicians in this field without making creative efforts are within the scope of protection of the present invention.
[0024] like Figures 1 to 4As shown, this embodiment proposes a drive device for material transportation, including a conveying pipe 1, a feed pipe 10, and a discharge pipe 11. A first motor 3 is provided at one end of the conveying pipe 1. A spiral conveying structure is provided inside the conveying pipe 1. The spiral conveying structure is connected to the first motor 3. The spiral conveying structure includes a screw 2, a first spiral blade 20, and a second spiral blade 21. The first spiral blade 20 and the second spiral blade 21 are both fixed to the screw 2. The first spiral blade 20 and the second spiral blade 21 have different spiral starting angles, and the first spiral blade 20 and the second spiral blade 21 have the same spiral direction. The conveying pipe 1 is a channel for material transportation. The cross-section of the conveying pipe 1 is a "U"-shaped structure, which is a common U-shaped pipe. The feed pipe 10 is the opening through which materials enter the conveying pipe 1. The feed pipe 10 should be located above the conveying pipe 1, using gravity to cause the materials to fall into the conveying pipe 1. The feed pipe 10 should extend upward to form a funnel-shaped inlet, so that the feed pipe 10 can help guide the materials to flow smoothly into the conveying pipe 1 from above, avoiding overflow and spillage of the materials. It can also allow the materials to be initially evenly distributed before entering the conveyor, avoiding excessive concentration or accumulation of materials on one side of the conveyor, thereby ensuring the stable operation of the conveyor. The discharge pipe 11 is the outlet after the materials are transported to the end point. The discharge pipe 11 should be located below the conveying pipe 1 and, like the feed pipe 10, use gravity to cause the materials to fall out of the conveying pipe 1. The first and second spiral blades 20, 21 are used to move material from one end of the conveying pipe 1 to the other through their spiral motion, achieving a conveying effect. The double-helical blade structure, in which the first and second spiral blades 20, 21 are arranged on the same screw 2, allows the screw conveyor to perform two spiral motions simultaneously on the same axis. As a result, the screw conveyor conveys more material per revolution than a single-blade screw conveyor, thereby improving conveying efficiency. The double-helical blade structure also disperses material more evenly, ensuring a more stable flow during conveying and reducing the risk of material blockage and obstruction. It also offers better adaptability to different types and properties of materials, resulting in a more stable and reliable conveying effect, meeting a wider range of conveying needs. The first and second spiral blades 20, 21 have different spiral starting angles, creating different conveying paths during conveying, increasing the diversity of material flow and further improving conveying efficiency and stability. The first and second spiral blades 20, 21 rotate in the same direction, ensuring that the material moves in the same direction within their conveying paths during rotation, preventing material from moving in opposite directions and causing material failure.
[0025] In this embodiment, the spiral starting angles of the first spiral blade 20 and the second spiral blade 21 differ by 180 degrees, and the spiral pitches of the first spiral blade 20 and the second spiral blade 21 are the same. The spiral starting angles of the two spiral blades differ by 180 degrees, so that during the conveying process, the two blades complement each other, and the material can be divided by a spiral blade every half turn, so that the material can be more evenly distributed in the conveying channel of the conveyor, and the material is less likely to be blocked or stuck. The spiral pitches of the two spiral blades are the same, that is, the distance between the two blades is the same, and the size of the conveying path formed by them is also the same, which can ensure that the flow speed and stability of the material are relatively consistent during the conveying process, thereby maintaining stable conveying efficiency.
[0026] In this embodiment, the spiral pitch of the first spiral blade 20 and the second spiral blade 21 gradually increases from the end of the screw 2 toward the first motor 3 to the end of the screw 2 away from the first motor 3. The gradual increase in the spiral pitch can gradually stretch and disperse the material during the conveying process. For materials with strong viscosity or easy to agglomerate, the gradually increasing spiral pitch can reduce adhesion and accumulation between materials, thereby avoiding uneven flow of materials during the conveying process. The gradual increase in the spiral pitch can reduce the blockage and obstruction of materials during the conveying process. When the material flows inside the conveyor, the gradually increasing spiral pitch can reduce the friction and extrusion between the materials, reduce the adhesion of the materials, and thus reduce the occurrence of blockage and obstruction.
[0027] In this embodiment, a reducer 4 is provided between the screw 2 and the first motor 3. The screw 2 and the first motor 3 are both fixedly connected to the reducer 4. A fixed housing 12 extends from one end of the conveying pipe 1 toward the reducer 4, and the reducer 4 is fixedly connected to the fixed housing 12. The reducer 4 is used to reduce the rotational speed. The rotational speed of the first motor 3 is usually high, and the conveyor does not require such a high rotational speed, so the reducer 4 is needed to reduce the rotational speed; and to increase torque. The reducer 4 can increase the torque during power transmission, that is, the rotational torque that can be provided by the output end. This can help the conveyor overcome friction and resistance when conveying materials and ensure the normal operation of the conveyor. By reducing the rotational speed of the transmission system and increasing the torque, the reducer 4 reduces the direct contact between the first motor 3 and the conveyor, thereby protecting the transmission system. The reducer 4 can also extend the service life of the transmission system by dispersing and absorbing shocks and vibrations in the transmission system. The fixed housing 12 is used to fix the reducer 4 so that the reducer 4 can operate stably.
[0028] In this embodiment, a bearing 5 is provided between the reducer 4 and the screw 2. The bearing 5 is sleeved on the screw 2 and is rotatably connected to the screw 2. The bearing 5 is provided with a fixing structure 50 for fixing the bearing 5. The fixing structure 50 is sleeved on the bearing 5 and is rotatably connected to the bearing 5. The fixing structure 50 is fixedly connected to the reducer 4 and the fixed housing 12. The bearing 5 is used to reduce vibration and noise. The bearing 5 can provide good support and guidance, which can reduce friction and impact between the various components of the conveyor, reduce the generation of vibration and noise, and improve the working environment. The fixing structure 50 uses a bearing 5 seat, and the bearing 5 is installed in the bearing 5 seat. The bearing 5 seat is fixedly connected to the reducer 4 and the fixed housing 12.
[0029] In this embodiment, the feed pipe 10 is provided with a plurality of discharge barrels 6, and the plurality of discharge barrels 6 are arranged in a circle around the feed pipe 10. The end of the discharge barrel 61 is connected to the discharge barrel 61, and the end of the discharge barrel 61 away from the discharge barrel 6 is connected to the feed pipe 10. A plurality of material limiting structures for limiting the discharge speed are provided in the discharge barrel 6. The plurality of discharge barrels 6 are used to store different materials, and the discharge speed of the materials is controlled by the material limiting structure. The plurality of discharge barrels 6 are arranged in a circle around the feed pipe 10 to maximize the use of space, reduce the equipment footprint, facilitate the uniform transportation of materials, and avoid the accumulation or deviation of certain materials. The discharge barrel 61 is used to connect the discharge barrel 6 and the feed pipe 10, and collect the materials in each discharge barrel 6 into the feed pipe 10.
[0030] In this embodiment, the material limiting structure includes a second motor 62 and a rotating rod 63. The second motor 62 is located on the upper side of the discharge barrel 6. The second motor 62 is fixedly connected to the discharge barrel 6. The rotating rod 63 is located inside the discharge barrel 6. One end of the rotating rod 63 is connected to the second motor 62. The rotating rod 63 extends toward the discharge pipe 61 and extends into the discharge pipe 61. A spiral stirring blade 66 is provided at one end of the rotating rod 63 located at the discharge pipe 61. The spiral diameter of the spiral stirring blade 66 is the same as the inner diameter of the discharge pipe 61. The rotating rod 63 is provided with a stirring structure for preventing material accumulation and agglomeration. The second motor 62 is used to drive the rotating rod 63 and the stirring structure and spiral stirring blade 66 thereon to rotate. The rotating rod 63 is used to connect the second motor 62 and the spiral stirring blade 66 to transmit the rotational power of the motor and at the same time install a stirring structure for preventing material accumulation and agglomeration. The spiral stirring blade 66 is responsible for pushing the material downward and conveying it evenly. The spiral diameter of the spiral stirring blade 66 is the same as the inner diameter of the discharge tube 61, so that the spiral blade can completely match the discharge tube 61, and the material can only enter the discharge tube 61 through the spiral stirring blade 66, thereby achieving control of the material discharge speed. By controlling the speed of the second motor 62, and thus the rotation speed of the spiral stirring blade 66, the material discharge speed is controlled. By controlling the speed of the second motor 62 of different discharge barrels 6, the discharge speed of different materials is controlled, thereby achieving control of different material ratios.
[0031] In this embodiment, the stirring structure includes a plurality of stirring rods 64 and a plurality of stirring plates 65. The plurality of stirring rods 64 and stirring plates 65 are arranged in a circle around the rotating rod 63. The stirring plates 65 are close to the spiral stirring blades 66, and the stirring rods 64 are close to the second motor 62. The stirring rods 64 and stirring plates 65 extend toward the inner wall of the lower barrel 6. Driven by the rotating rod 63, the stirring rods 64 stir the upper portion of the lower barrel 6. Their function is to prevent the accumulation and agglomeration of materials in the upper portion of the lower barrel 6 and ensure that the materials can fall smoothly. At the same time, the presence of the stirring rods 64 helps to evenly disperse the materials and prevent the formation of bridges or voids in the materials within the lower barrel 6, thereby ensuring the continuity and stability of the material discharge. The stirring plate 65 is driven by the rotating rod 63 to stir the lower part of the discharge barrel 6. Its function is to prevent the material from agglomerating and clogging near the spiral stirring blade 66, ensuring that the material can smoothly enter the discharge pipe 61; the stirring plate 65 can evenly disperse the material and push it to the spiral stirring blade 66, so that the material is fully stirred before entering the discharge pipe 61, avoiding blockage in the discharge pipe 61.
[0032] The above are only preferred embodiments of the present invention and are not intended to limit the present invention. Any modifications, equivalent replacements, improvements, etc. made within the spirit and principles of the present invention should be included in the scope of protection of the present invention.
