Detailed Implementation

[0025] The embodiments of this utility model are described in detail below. Examples of these embodiments are shown in the accompanying drawings, wherein the same or similar reference numerals denote the same or similar elements or elements having the same or similar functions throughout. The embodiments described below with reference to the accompanying drawings are exemplary and are only used to explain this utility model, and should not be construed as limiting this utility model.

[0026] Please refer to Figure 1-5One embodiment of this utility model is: a powder lifting and conveying device, including a base 1, which provides stable support for the entire device. A screw conveyor body 2 is connected to the top of the base 1 via a bracket. The screw conveyor body 2 consists of a cylinder, screw blades, and a motor. The motor of the screw conveyor body 2 is connected to a power supply system via a switch and wires for easy control. During operation, the motor drives the screw blades inside the screw conveyor to rotate, and the blades push the powder upwards along the conveyor cylinder wall. The powder is then conveyed to a receiving device via a discharge pipe 3, a corrugated pipe 4, and a discharge pipe 5, achieving continuous and stable lifting and conveying of the powder. A feed hopper is connected to the outer wall of the screw conveyor body 2, through which the powder is fed... The hopper can quickly replenish powder raw materials into the screw conveyor body 2. The four corners of the base 1 are connected to casters 19 via brackets, allowing for easy movement of the equipment and quick switching to different working areas to adapt to receiving devices, thus improving the equipment's versatility. A discharge pipe 3 is connected to the outer wall of the screw conveyor body 2, and a corrugated pipe 4 is connected to the bottom of the discharge pipe 3. The corrugated pipe 4 has flexible and telescopic characteristics, adapting to receiving devices of different heights, preventing powder spillage due to excessive distance between the discharge port and the receiving device, and reducing material waste. A second discharge pipe 5 is connected to the bottom of the corrugated pipe 4. The screw conveyor body 2 is equipped with an adjustment mechanism that connects the discharge pipe 3, corrugated pipe 4, and discharge pipe 5. The material pipe 25, in conjunction with the adjustment mechanism, allows for flexible adjustment of the material discharge height without disassembling the equipment or replacing the support frame, fundamentally solving the problems of cumbersome height adjustment and reduced efficiency associated with traditional equipment. The adjustment mechanism includes two fixed plates 6, which are connected opposite each other to the outer wall of the screw conveyor body 2. A mounting frame 7 is slidably connected between the two fixed plates 6. Slide grooves are provided on the opposite surfaces of the two fixed plates 6. The front and rear sides of the mounting frame 7 are slidably connected within the slide grooves, providing a clear movement trajectory for the mounting frame 7. This ensures that the mounting frame 7 slides only in the vertical direction, preventing the corrugated pipe 4 from twisting or the material discharge port from shifting due to vibration of the mounting frame 7. A rectangular section is provided on the right side of the mounting frame 7. The inner wall of the rectangular hole 8 is slidably connected to four sliders 9. The sliders 9 slide along the rectangular hole 8 to guide the extension and retraction of the bellows 4 and reduce wear. The outer wall of the bellows 4 is fixedly fitted with four connecting clamps 10. The outer walls of the four connecting clamps 10 are respectively connected to the left side of the four sliders 9. The connecting clamps 10 fix the bellows 4 and prevent the bellows 4 from being excessively twisted or pulled during the adjustment process. The right side of each slider 9 is hinged with a hinge arm 11, and the opposite ends of two adjacent hinge arms 11 are hinged. The four sliders 9 are linked by the hinge arms 11 and can synchronously drive the connecting clamps 10 to drive the bellows 4 to extend and retract, so that the height of the feed tube 2 5 is adjusted evenly and the feeding skew caused by unilateral deviation is avoided.

[0027] An electric telescopic rod 12 is connected to the bottom inner wall of the rectangular hole 8. The piston end of the electric telescopic rod 12 is connected to the bottom slider 9. The electric telescopic rod 12 is self-locking and is electrically connected to an external PLC controller for easy control. During operation, the internal motor drives the internal screw drive to convert the rotational motion into the linear extension and retraction of the piston, which drives the connected slider 9 to slide along the rectangular hole 8. The electric telescopic rod 12 provides automatic power to the slider 9, driving the articulated arm 11 to adjust the feeding height in conjunction. No manual operation is required, which is especially suitable for high-frequency adjustment scenarios and greatly improves work efficiency. After the height is adjusted to the correct position, it automatically locks when the power is turned off to prevent the feeding pipe 2 5 from shifting due to equipment vibration or powder impact.

[0028] Please refer to Figure 1-5 Based on the above embodiments, in another embodiment of this utility model, a shaking mechanism is provided on the two fixed plates 6. The shaking mechanism includes a connecting frame 13, which is connected to the right side of the two fixed plates 6. The inner cavity of the connecting frame 13 is rotatably connected to a rotating shaft 14 through a bearing. The left end of the rotating shaft 14 is connected to a turntable 15, and the left side of the turntable 15 is connected to a sliding rod 16. A sliding hole 17 is provided on the upper right side of the mounting frame 7. The sliding hole 17 is "O" shaped. The sliding rod 16 is eccentrically set, and the outer wall of the sliding rod 16 is slidably connected to the sliding hole 17. The rotating shaft 14 drives the turntable 15 to rotate, and the turntable 15 drives the eccentric sliding rod 16 to slide in the sliding hole 17, which can drive the mounting frame 7 to achieve small-range up and down shaking, avoiding powder from sticking to the corrugated pipe 4.

[0029] A drive motor 18 is connected to the right side of the connecting frame 13. The drive motor 18 is connected to the power supply system through a switch and wires for easy control. The right end of the rotating shaft 14 passes through the connecting frame 13 and is connected to the output end of the drive motor 18. By starting the drive motor 18, the rotating shaft 14 is driven to rotate. The drive motor 18 provides stable power to the rotating shaft 14, which drives the turntable 15 and the slide bar 16 to run automatically, realizing the shaking of the mounting frame 7. No manual operation is required, further reducing labor intensity.

[0030] The working principle of this utility model is as follows: When conveying powder, the raw material is fed into the feed hopper, the screw conveyor body 2 is started, and the powder is lifted and then conveyed to the receiving equipment through the first discharge pipe 3, the corrugated pipe 4, and the second discharge pipe 5; the movable wheels 19 at the bottom of the base 1 can drive the equipment to move flexibly and adapt to different working areas; when adjusting the discharge height, the electric telescopic rod 12 at the bottom of the rectangular hole 8 is activated, and its piston end drives the lowest slider 9 to slide along the rectangular hole 8. The adjacent sliders 9 are linked through the hinge arm 11, which drives the four sliders 9 to move synchronously. The sliders 9 are connected by the left side of the connecting rod. The coupling 10 causes the corrugated pipe 4 to contract, thereby adjusting the height of the feed pipe 2 5. This eliminates the need to disassemble the equipment or replace the support frame, significantly improving work efficiency. To prevent powder blockage, the drive motor 18 is started, and its output end drives the rotating shaft 14 and the left-side turntable 15 to rotate. The slide rod 16, which is eccentrically set on the left side of the turntable 15, slides along the "O"-shaped sliding hole 17 on the upper right side of the mounting frame 7, driving the mounting frame 7 to vibrate up and down in a small range along the slide groove. The vibration is transmitted to the corrugated pipe 4 through the slider 9 and the coupling 10, effectively preventing powder from sticking to the inner wall of the corrugated pipe 4 and ensuring smooth feeding.
