Description

Technical Field

[0001] This utility model relates to the field of material conveying technology, specifically to a steerable multi-angle screw conveyor structure. Background Technology

[0002] A screw conveyor is a mechanical device that uses rotating helical blades to continuously transport materials along a closed trough or pipeline. Its core component is a rotating shaft with helical blades. By rotating, it propels powdery, granular, or small lump materials forward. It can achieve horizontal, inclined, and even vertical conveying. It has the advantages of simple structure, good sealing, flexible layout, and convenient maintenance. It is widely used in the short-distance conveying of bulk materials in industries such as grain, chemical, building materials, and environmental protection. However, it should be noted that it is not suitable for conveying easily perishable sticky materials or large hard substances, and its efficiency may be affected by increased energy consumption when the conveying distance is too long.

[0003] The steerable multi-angle screw conveyor is a device that achieves multi-angle material conveying through the overall rotation or oscillation of the conveying pipe. Its core lies in the special connection design between the rotating shaft and the conveying pipe, which allows the conveying pipe to flexibly adjust its direction under power drive without relying on traditional bends for steering. This maintains the continuous pushing function of the screw blades and ensures that materials can still be stably conveyed at different angles. It has the advantages of compact structure, good sealing performance, and strong adaptability, and is widely used in bulk material conveying scenarios that require flexible layout.

[0004] In the application of screw conveyors, the angle is currently adjusted by rotating or oscillating the conveying pipe as a whole. However, this design has obvious technical defects. Due to the uneven force during rotation or oscillation, concentrated stress will be generated at the connection between the shaft and the conveying pipe, which can easily lead to fatigue damage or even shaft breakage, seriously affecting the safety and service life of the equipment. Therefore, a multi-angle steerable screw conveyor structure is proposed to solve the problems mentioned above. Utility Model Content

[0005] To address the shortcomings of existing technologies, this utility model provides a steerable multi-angle screw conveyor structure, which has advantages such as making stress distribution more uniform and reducing fatigue caused by stress during rotation. It solves the problem that when adjusting the rotation angle of existing screw conveyors, uneven stress during rotation or oscillation will cause concentrated stress at the connection between the shaft and the conveying pipe, which is very easy to cause fatigue damage and even shaft breakage accidents, seriously affecting the safety and service life of the equipment.

[0006] To achieve the above objectives, this utility model provides the following technical solution:

[0007] A steerable multi-angle screw conveyor structure includes a conveying cylinder and a bottom plate, wherein the outer wall of the conveying cylinder is provided with a steering structure;

[0008] The steering structure includes a side plate fixedly connected to the top of the base plate, a top plate fixedly connected to the top of the side plate, a reduction motor fixedly connected to the top of the top plate, a first rotating shaft fixedly connected to the output shaft of the reduction motor, two connecting rods fixedly connected to the outer peripheral wall of the first rotating shaft, a second rotating shaft fixedly connected to the top of the conveying cylinder, and two mounting plates fixedly connected to both the front and rear sides of the conveying cylinder, with universal pulleys rotatably connected to the bottom of the mounting plates.

[0009] Furthermore, a drive motor is fixedly connected to the right end of the conveying cylinder, and a spiral conveying blade is fixedly connected to the output shaft of the drive motor. The spiral conveying blade is rotatably connected to the inner circumferential wall of the conveying cylinder.

[0010] Furthermore, two support arms are fixedly connected to the left side of the side plate, and the side of the support arm away from the side plate is fixedly connected to the bottom of the top plate, and the support arm is installed at an inclined angle.

[0011] Furthermore, a support rod is fixedly connected between the support arm and the base plate, and there are two support rods.

[0012] Furthermore, mounting bases are fixedly connected to both the front and rear sides of the base plate, and two fastening screws slide through the interior of each mounting base.

[0013] Furthermore, a feed seat is fixedly connected to the top of the conveying cylinder, a feed inlet is opened on the top of the conveying cylinder, the feed seat is connected to the top of the feed inlet, and a discharge outlet is opened on the left side of the conveying cylinder.

[0014] Furthermore, the first rotating shaft is fixedly connected to the top of the conveying cylinder, and the ends of the two connecting rods away from the first rotating shaft are fixedly connected to the outer peripheral wall of the second rotating shaft. The first rotating shaft and the second rotating shaft are symmetrically distributed from left to right.

[0015] Furthermore, the four mounting plates are symmetrically distributed from left to right, and the bottom of the universal pulley is on the same horizontal plane as the bottom of the base plate.

[0016] Compared with the prior art, this utility model provides a steerable multi-angle screw conveyor structure, which has the following beneficial effects:

[0017] This steerable multi-angle screw conveyor structure uses a geared motor and a first rotating shaft to drive the conveyor cylinder to rotate and adjust the angle. Two connecting rods mounted on the first rotating shaft are connected to a second rotating shaft mounted on the conveyor cylinder, dispersing and transferring stress between the first rotating shaft and the conveyor cylinder. This effectively avoids excessive stress concentration at the root of the rotating shaft or at the connection point, greatly improving the stability and reliability of the equipment operation, and significantly extending the service life of the core components. This allows the screw conveyor to achieve a wide range of highly reliable multi-angle steering without the need for bends, providing greater flexibility and design freedom for the layout of material conveying systems, while reducing maintenance costs and safety hazards caused by equipment failure.
