[0002] Powder metallurgy is a process technology that produces metal powders or uses metal powders as raw materials, and manufactures metal materials, composite materials and various types of products through forming and sintering. Workpieces made using metal powders have superior properties that cannot be obtained from other materials.

[0003] Currently, when processing alloy powder, a conveying device is needed to transport multiple alloy powders in a specific ratio to the processing equipment. However, the existing conveying device has a simple structure, which makes it inconvenient to pre-mix multiple alloy powders before conveying, thus affecting the processing quality of subsequent products. In addition, its own conveying height cannot be flexibly adjusted, making it difficult to better adapt to the material conveying needs of processing equipment with different heights.

The conveying cylinder is welded to the two connecting blocks. The telescopic effect of the two electric push rods can flexibly adjust the conveying height of the conveying cylinder, thereby better adapting to the material conveying needs of subsequent processing equipment of different heights and helping to improve adaptability and practicality.

Obviously, the described embodiments are only some embodiments of the present utility model, and not all embodiments.

[0024] Reference Figure 1-4 This embodiment discloses an alloy powder premixing and conveying device, which includes a base 1 with universal wheels equipped with brakes installed at all four corners of the bottom, a height adjustment mechanism, a material conveying mechanism, and a material premixing mechanism;

[0025] In this embodiment, a mounting plate 19 is fixedly connected to the top outer wall of the base 1, and a controller 20 and a frequency converter 21 are fixedly installed on the front outer wall of the mounting plate 19 in sequence.

The frequency converter 21 can flexibly adjust the speed of the variable frequency motor 15, thereby facilitating the flexible adjustment of the material conveying speed to meet different processing requirements;

[0027] Specifically, the material premixing mechanism includes a premixing chamber 5 fixedly connected to one end of the top of the conveying cylinder 4, a stirring driver located at the top of the premixing chamber 5, a support rod 6 fixedly connected to the outer wall of the top of the premixing chamber 5, a stirring shaft 7 rotatably mounted on the support rod 6, and a double helical stirring blade 8 and a single helical stirring blade 9 sequentially welded to the stirring shaft 7.

[0028] Furthermore, the bottom of the premixing chamber 5 is a conical structure, and the single spiral stirring blade 9 is located inside the conical structure. In this way, the single spiral stirring blade 9 rotates inside the conical structure, which can prevent the material from accumulating at the bottom of the premixing chamber 5 and causing blockage.

[0029] Furthermore, the stirring actuator includes a fixed cover 10 fixedly connected to the top outer wall of the support rod 6, a drive motor 11 fixedly installed on the top outer wall of the fixed cover 10, a drive gear 12 fixedly mounted on the output shaft of the drive motor 11, and a transmission gear 13 fixedly mounted on the top end of the stirring shaft 7. The output shaft of the drive motor 11 passes through the top of the fixed cover 10, and the drive gear 12 and the transmission gear 13 mesh with each other and are both located inside the fixed cover 10.

[0030] Specifically, the height adjustment mechanism includes two electric push rods 2 symmetrically fixed to the top outer wall of the base 1 and two connecting blocks 3 sequentially fixed to the telescopic ends of the two electric push rods 2. The conveying cylinder 4 is welded to the two connecting blocks 3. Both electric push rods 2 are electrically connected to the controller 20. The telescopic effect of the telescopic ends of the two electric push rods 2 can flexibly adjust the conveying height of the conveying cylinder 4, thereby better adapting to the material conveying needs of subsequent processing equipment of different heights and helping to improve adaptability and practicality.

[0031] In this embodiment, a feeding pipe 18 is fixedly connected to one bottom end of the conveying cylinder 4. The feeding pipe 18, the premixing chamber 5, and the conveying cylinder 4 are integrally formed.

[0032] Working principle: First, various alloy powders prepared in a specific ratio are added into the premixing chamber 5. At this time, the drive motor 11 controls the drive gear 12 to rotate. Then, the transmission gear 13 meshing with the drive gear 12 will drive the stirring shaft 7 to rotate. Thus, the double helical stirring blades 8 and single helical stirring blades 9 on the stirring shaft 7 rotate together to fully mix the various powders. This facilitates the premixing of the required alloy powders before transmission, which helps to improve the processing quality of subsequent products.

[0033] Secondly, the variable frequency motor 15 drives the spiral conveyor blades 17 on the transmission shaft 16 to rotate. The driving force generated by the rotation of the spiral conveyor blades 17 can push the mixed alloy powder forward and discharge it from the feed pipe 18 to complete the material transfer work.
