[0023] The following will be combined with the drawings in the embodiments of the utility model to clearly and completely describe the technical solutions in the embodiments of the utility model. Obviously, the described embodiments are only part of the embodiments of the utility model, not all of the embodiments. Based on the embodiments in the utility model, all other embodiments obtained by ordinary technicians in this field without creative work are within the scope of protection of the utility model.

[0024] like Figure 1 As shown, the present application provides a feeding device for an ultrasonic rotary vibrating screen for metal powder, comprising a frame 1, and a hopper 11 mounted on the frame 1, the hopper 11 being used to store metal powder;

[0025] A conveying pipe 13 connected to the hopper 11 is installed at the bottom of the hopper 11, and a discharge pipe 131 is installed at the end of the conveying pipe 13 away from the hopper 11. The discharge pipe 131 is connected to the conveying pipe 13 and discharges the metal powder in the conveying pipe 13 to the outside;

[0026] A conveying unit 2 is arranged on the conveying pipe 13, and the conveying unit 2 includes a spiral body 22 (see FIG. Figure 2), and the spiral body 22 is in the conveying pipe 13, and the spiral body 22 is composed of a rotating shaft connected to the bearings at both ends of the conveying pipe 13, and spiral blades arranged on the outer ring of the rotating shaft. The rotation of the spiral body 22 can convey the metal powder stored in the hopper 11 to the discharge pipe 131;

[0027] The end of the rotating shaft away from the discharge pipe 131 extends outward from the conveying pipe 13 and is connected to a motor 21, which is suitable for driving the spiral body 22 to rotate and output the metal powder in the hopper 11 to the discharge pipe 131 through the cooperation of the conveying pipe 13. In the present application, the conveying unit 2 is a screw conveyor, which is a prior art. Please refer to the prior art for details, and no further details will be given here.

[0028] like Figure 2-Figure 3 As shown, a base 12 is installed at the end of the frame 1, and a feed pipe 131 passes through the base 12 and extends to the bottom of the base 12, and a feeding mechanism 3 is installed at the bottom of the base 12, and the feeding mechanism 3 is used to feed materials into the ultrasonic rotary vibrating screen;

[0029] The feeding mechanism 3 includes a hanger 31 fixedly mounted on the bottom of the pedestal 12, and slide rails 32 mounted on both sides of the hanger 31, the two sets of slide rails 32 are arranged opposite to each other, and a slide groove 322 is opened on the slide rails 32, and a transfer pipe 321 is fixedly installed between the two sets of slide rails 32, and the transfer pipe 321 is connected to the feed pipe 131;

[0030] A slide plate 33 adapted to the slide groove 322 is provided between the two sets of slide rails 32. The slide plate 33 is suitable for sliding along the slide groove 322, and an opening corresponding to the transfer tube 321 is provided on the slide plate 33. At the same time, a blocking area (not marked in the figure) is provided on the side of the slide plate 33 away from the transfer tube 321. The blocking area is suitable for blocking the transfer tube 321.

[0031] At the same time, a material receiving pipe 35 is arranged below the slide plate 33. The material receiving pipe 35 is a through type and is fixedly installed at the opening of the slide plate 33. A cover plate 351 is arranged at the bottom of the material receiving pipe 35. The cover plate 351 is hinged to the barrel wall of the material receiving pipe 35 so that the cover plate 351 is suitable for rotation and closing or opening the material receiving pipe 35. When the cover plate 351 is on the hanger 31, the cover plate 351 closes the bottom of the material receiving pipe 35 under the action of the hanger 31. At this time, the material receiving pipe 35 is in a closed state. When the material receiving pipe 35 moves to the edge of the hanger 31, the cover plate 351 flips over under the action of its own gravity or external force and opens the material receiving pipe 35. At this time, the material receiving pipe 35 is in an open state.

[0032] At the same time, a sealing ring (not shown in the figure) is installed on the cover plate 351, and the sealing ring is suitable for contacting with the bottom of the material receiving tube 35 to seal and close the bottom of the material receiving tube 35;

[0033] A cylinder 34 is also installed on the hanger 31. The output end of the cylinder 34 is connected to the material receiving pipe 35, and the cylinder 34 is used to push the material receiving pipe 35 to move on the hanger 31.

[0034] When conveying metal powder, the motor 21 drives the spiral body 22 to rotate and convey the metal powder in the hopper 11 to the discharge pipe 131, so that the metal powder is conveyed through the discharge pipe 131;

[0035] When it is necessary to input metal powder into the receiving tube 35, the opening of the slide plate 33 corresponds to the transfer tube 321, and because the receiving tube 35 is connected to the slide plate 33, the receiving tube 35 is connected to the feeding tube 131 through the transfer tube 321, so that the material is input into the receiving tube 35, and at this time the receiving tube 35 is in a closed state, so that the receiving tube 35 can receive the material;

[0036] At the same time, a limiting rod 352 is fixed on the outer wall of the material receiving tube 35, and limiting grooves 312 adapted to the limiting rod 352 are opened on the inner walls of both sides of the hanger 31. The limiting rod 352 is suitable for sliding along the limiting groove 312 and limiting the movement of the material receiving tube 35. At the same time, an arc opening 311 (such as Figure 2 As shown in FIG. 3 , the arc opening 311 is used to facilitate the flipping of the cover plate 351 of the material receiving tube 35;

[0037] When it is necessary to add material to the ultrasonic rotary vibrating screen, the ultrasonic rotary vibrating screen is located at one side of the pedestal 12 and below the slide rail 32. At the same time, the cylinder 34 drives the material receiving pipe 35 to move, and indirectly drives the slide plate 33 to move. At this time, the transfer pipe 321 and the material receiving pipe 35 are separated from each other, and the blocking area of ​​the slide plate 33 closes the transfer pipe 321. When the material receiving pipe 35 moves to the arc opening 311 of the hanger 31, the cover plate 351 is opened under the force applied by the metal powder in the material receiving pipe 35, and the metal powder in the material receiving pipe 35 is output to the ultrasonic rotary vibrating screen, thereby achieving the purpose of quantitative feeding of the ultrasonic rotary vibrating screen.

[0038] After the ultrasonic vibrating screen is charged, the cylinder 34 drives the receiving pipe 35 to move back, and under the action of the arc opening 311, the cover plate 351 closes the receiving pipe 35, and the slide plate 33 moves synchronously with the receiving pipe 35, so that the receiving pipe 35 is connected with the transfer pipe 321, and the metal powder continues to be fed into the receiving pipe 35;

[0039] To sum up, through the cooperation between the receiving tube 35 and the cover plate 351, the receiving tube 35 is suitable for opening or closing. When the receiving tube 35 is in a closed state, the receiving tube 35 is connected with the discharge tube 131 to input metal powder into the receiving tube 35. The receiving tube 35 is suitable for moving toward the edge of the hanger 31 under the drive of the cylinder 34, and when the receiving tube 35 is at the edge of the hanger 31, the receiving tube 35 is in an open state, and the metal powder is input toward the ultrasonic rotary vibrating screen, thereby achieving the effect of quantitative feeding to the ultrasonic rotary vibrating screen.

All technical solutions under the concept of the present invention belong to the protection scope of the present invention. It should be pointed out that for ordinary technicians in this technical field, some improvements and modifications without departing from the principle of the present invention should also be regarded as the protection scope of the present invention.
