[0012] 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.

[0013] like Figure 1-4 As shown, this utility model provides a technical solution: A convenient grain processing elevator includes a U-shaped support frame 1, with a U-shaped lifting frame 2 installed above it. A lifting mechanism is provided between the U-shaped lifting frame 2 and the U-shaped support frame 1. The lifting mechanism includes a motor 4 fixedly connected to the upper bottom surface of the U-shaped support frame 1, and a crossbeam 5 fixedly connected to the lower middle part of the U-shaped support frame 1. A sleeve 6 is rotatably connected to the middle part of the crossbeam 5 via a bearing. The output shaft of the motor 4 is fixedly connected to the bottom end of the sleeve 6. A lead screw 7 is threadedly connected inside the sleeve 6, and the top end of the lead screw 7 is fixedly connected to the U-shaped support frame 1. At the bottom center of the lifting frame 2, a telescopic dust cover 8 is movably fitted onto the outside of the lead screw 7. The upper and lower ends of the telescopic dust cover 8 are fixedly connected to the U-shaped lifting frame 2 and the sleeve 6, respectively. The lifting pipe 3 is located above the U-shaped support frame 1. The left ends of the lifting pipe 3 are rotatably connected to the U-shaped lifting frame 2 via bearings. A drive mechanism is provided at the right end of the lifting pipe 3. The drive mechanism includes a gearbox 11 fixedly connected between the lifting pipe 3 and the right side of the feeding hopper 9, and spur gears 12 and 133 rotatably connected to the two ends inside the gearbox 11 via bearings. Spur gear 13 meshes with spur gear 12. Motor 14 is fixedly connected to the outside of the right side of gearbox 11. The output shaft of motor 14 is fixedly connected to spur gear 12. An auger 15 is installed inside the lifting pipe 3. Spur gear 13 and auger 15 are coaxially fixed together via connecting shaft 16. A feeding hopper 9 is fixedly connected to the top right side of the lifting pipe 3. A feeding port 10 is formed between the inner bottom wall of the feeding hopper 9 and the upper end of the lifting pipe 3. A discharge pipe 17 is fixedly connected to the lower end of the lifting pipe 3 on the side away from the feeding hopper 9. A blocking plate 18 is detachably connected to the end of the lifting pipe 3 away from the feeding hopper 9 by bolts. An auxiliary walking mechanism is provided on the outside of the right side of the lifting pipe 3. The auxiliary walking mechanism includes a walking frame 19 fixedly connected to the outside of the lifting pipe 3, and walking wheels 20 rotatably connected to the bottom ends of the walking frame 19 by bearings. Triangular stabilizers 21 are fixedly connected to both sides of the U-shaped support frame 1. Slide grooves 22 are provided on the inner walls of both sides of the U-shaped support frame 1, and sliders that slide in cooperation with the slide grooves 22 are fixedly connected to both ends of the U-shaped lifting frame 2. In this embodiment, the height of the lifting pipe 3 is adjustable by the threaded engagement between the sleeve 6 and the lead screw 7 driven by the motor 2 4, and the sliding engagement between the U-shaped lifting frame 2 and the U-shaped support frame 1. This allows the discharge port to adapt to the feeding height requirements of different processing equipment or storage facilities, solving the problem of fixed discharge port height and poor adaptability in the prior art, and improving production efficiency.

[0014] Furthermore, the sliding guide effect of the traveling wheels 20 when the lifting pipe 3 is raised ensures the stability and ease of movement of the equipment during the height adjustment process.

[0015] Working principle: When grain needs to be lifted, the second motor 4 drives the sleeve 6 to rotate. The sleeve 6 drives the lead screw 7 to move upward through the thread, thereby pushing the U-shaped lifting frame 2 to rise along the U-shaped support frame 1. At this time, one end of the lifting pipe 3 is lifted, and the traveling wheel 20 at the other end slides along the ground to guide it, ensuring that the lifting pipe 3 is tilted smoothly to a suitable height. The telescopic dust cover 8 extends and retracts with the lead screw 7 to protect the lead screw 7. Then, the first motor 14 drives the first spur gear 12 to rotate. The first spur gear 12 drives the second spur gear 13 to rotate in the opposite direction. The second spur gear 13 drives the auger 15 to rotate inside the lifting pipe 3 through the connecting shaft 16. Grain enters the lifting pipe 3 from the hopper 9 through the feed port 10. The auger 15 conveys the grain to the left to the discharge pipe 17 for discharge. If it is necessary to clean or maintain the inside of the lifting pipe 3, the blocking plate 18 can be disassembled for operation.

[0016] The foregoing has shown and described the basic principles, main features, and advantages of this utility model. Those skilled in the art should understand that this utility model is not limited to the above embodiments. The embodiments and descriptions in the specification are merely preferred examples and are not intended to limit the utility model.
