Detailed Implementation

[0020] 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.

[0021] See Figures 1-5In this embodiment of the utility model, a feeding device for preventing powder from clumping includes a base 1, a support frame 2 fixedly connected to the base 1, a hopper 3 fixedly connected to the support frame 2, a plurality of rotating shafts 4 rotatably connected inside the hopper 3, a roller 5 fixedly connected to the rotating shafts 4, and a plurality of circumferentially distributed stirring rods 6 fixedly connected to the outer wall of the roller 5.

[0022] The bottom of the hopper 3 is fixedly connected to a discharge trough 10, and the bottom of the discharge trough 10 is fixedly connected to a collection hopper 13. A sliding groove 11 is provided in the discharge trough 10. Multiple sets of equidistantly distributed first fixed rods 12 are fixedly connected in the sliding groove 11. Telescopic grooves 14 are fixedly connected at both ends of the sliding groove 11. Telescopic frames 15 are slidably connected in the telescopic grooves 14. Multiple sets of equidistantly distributed second fixed rods 16 are fixedly connected between the telescopic frames 15. The first fixed rods 12 and the second fixed rods 16 are perpendicular to each other. A discharge pipe 19 communicating with the bottom of the sliding groove 11 is provided at the bottom of the discharge trough 10.

[0023] A rotary drive assembly is installed on the hopper 3; a telescopic drive assembly is installed on the telescopic frame 15;

[0024] This invention first uses a hopper 3 to hold powder, and then a rotary drive assembly drives multiple sets of rotating shafts 4 to rotate synchronously. The rotating shafts 4 drive a stirring rod 6 to rotate via a roller 5, thereby stirring the powder in the hopper 3 and crushing any lumps in the powder. The crushed powder slides down the bottom of the hopper 3 into the discharge trough 10, and then slides down the discharge trough 10 towards the collection hopper 13. At this point, the powder slides over the chute 11, and this invention can then be activated by a telescopic drive. The component drives the telescopic frame 15 to reciprocate within the telescopic groove 14. The telescopic frame 15 drives the second fixed rod 16 to reciprocate within the sliding groove 11. At this time, the powder can be screened out through the screen formed by the first fixed rod 12 and the second fixed rod 16. At the same time, the reciprocating motion of the second fixed rod 16 clears the powder that is blocked between the first fixed rod 12 and the second fixed rod 16. Then, the qualified powder slides down the sliding groove 11 into the discharge pipe 19, while the remaining blocky material slides down the discharge chute 10 into the collection hopper 13.

[0025] In one instance of this embodiment, please refer to Figures 1-5 The bottom of the hopper 3 is fixedly connected to a grid 9. The present invention uses the grid 9 to filter out large pieces of material in the hopper 3, and then uses a rotating stirring rod 6 to stir and crush the large pieces of material.

[0026] In one instance of this embodiment, please refer to Figures 1-5The rotary drive assembly includes a gear 8 fixedly connected to one end of the rotating shaft 4, with adjacent gears 8 meshing with each other. A motor 7 is fixedly connected to the hopper 3, and the output shaft of the motor 7 is fixedly connected to the drive end of the rotating shaft 4.

[0027] The rotary drive assembly first achieves synchronous drive of multiple sets of gears 8 through the meshing of multiple sets of gears 8, and then drives multiple sets of rotating shafts 4 to rotate synchronously through the motor 7.

[0028] In one instance of this embodiment, please refer to Figures 1-5 The telescopic drive assembly includes a connecting frame 17 fixedly connected to the telescopic frame 15, and a reciprocating drive motor 18 fixedly connected to the base 1. The output shaft of the reciprocating drive motor 18 is fixedly connected to the connecting frame 17.

[0029] The telescopic drive assembly drives the connecting frame 17 to reciprocate through the reciprocating drive motor 18, and the connecting frame 17 drives the telescopic frame 15 to slide back and forth in the telescopic groove 14.
