[0013] Compared with the prior art, the present invention has the following beneficial effects:

[0014] 1. The utility model can improve the stirring efficiency by setting a diamond-shaped barrel, and shake the metal powder in the diamond-shaped barrel evenly by rotating the diamond-shaped barrel. Since the shape of the diamond-shaped barrel is set to be diamond-shaped, the path of mixing efficiency can be increased during rotation. The diamond-shaped barrel will produce more complex eddy currents and flow paths, which is conducive to more thorough mixing of materials, especially powdered or granular materials. The diamond design may reduce dead corners or material accumulation areas in the mixing barrel, which is conducive to the uniform distribution of the mixed materials. The paddles set inside the diamond-shaped barrel can further improve the stirring efficiency. By setting the paddles according to different usage requirements, the shape of the diamond-shaped mixing barrel can be better utilized to improve the stirring efficiency, thereby achieving a faster mixing process and avoiding segregation caused by uneven shaking.

[0015] 2. The utility model can realize automatic opening of the feed cover by setting the right-hand clamping claw and the left-hand clamping claw. By controlling the first hydraulic cylinder to drive the first telescopic rod to move the mounting box up and down, the right-hand clamping claw and the left-hand clamping claw under the mounting box are adjusted to the appropriate position above the feed cover. Then, the motor in the mounting box drives the second gear to rotate, so that the right-hand rack meshed with the second gear moves to the right and the left-hand rack moves to the left, so that the right-hand clamping claw and the left-hand clamping claw are tightened and clamped on the abutment block of the feed cover and connected to the abutment block. When the first spring in the first spring groove is squeezed, it will shrink into the first spring groove. When the abutment block moves, it will drive the second rack fixed under the abutment block. When the second rack moves, the meshing third gear will rotate, so that the third rack on the card block that is meshed with the third gear drives the card block to move. At this time, the squeezed second spring will shrink into the second spring groove, thereby making the card block disengage from the clamping groove on the feed port, and then the first telescopic rod is controlled to shrink so that the right clamping jaw and the left clamping jaw will clamp the feed cover to realize automatic opening of the cover.

[0016] 3. The utility model can improve work efficiency by setting up a feed hopper. By controlling the third motor to rotate the fourth gear, the second slider is adjusted to above the feed port, and then the second hydraulic cylinder on the second fixed plate is controlled to adjust the second telescopic rod to lower the second telescopic rod, and the feed hopper installed on the third fixed plate is lowered to a suitable position. By controlling the third hydraulic cylinder to extend the third telescopic rod, the L-shaped baffle is pushed out, and the metal powder in the feed hopper enters the diamond barrel through gravity. The automated design improves work efficiency and is more convenient to use.

[0017] 4. The utility model can reduce the diffusion of dust by setting up a dust removal pipe. The metal dust during discharge is sucked into the connecting pipe through the dust removal pipe and discharged into the other end of the vacuum cleaner through the connecting pipe, thereby reducing the diffusion of dust, avoiding the metal powder being inhaled by workers, and ensuring the health of workers.

[0018] The parts not involved in the device are the same as those in the prior art or can be implemented by using the prior art. BRIEF DESCRIPTION OF THE DRAWINGS

[0035] like Figure 1 - Figure 5As shown, the guide rail 15 is movably connected with a second slider 34, and a third motor 36 is fixedly installed on one side of the second slider 34. The output shaft of the third motor 36 passes through the second slider 34 and is located inside the second slider 34.

A second fixed plate 37 is fixedly installed on the other side of the second slider 34. Two second hydraulic cylinders 38 are fixedly installed on the second fixed plate 37.

[0036] like Figure 1 - Figure 7As shown, the feed cover 5 has two plug-in slots 28 on its circumference, and the first springs 29 are fixedly installed on the inner sides of the upper ends of the two plug-in slots 28, and the two first springs 29 are connected to abutment blocks 30 at one end, and the two abutment blocks 30 are respectively plugged into one end of the first spring 29, and a first spring slot 47 is provided on one side of the two abutment blocks 30, and one end of the two first springs 29 is fixedly connected to the first spring slot 47, and the second rack 32 is fixedly installed on the lower ends of the two abutment blocks 30, and the second spring 49 is fixedly installed on the inner sides of the lower ends of the two plug-in slots 28, and one end of the two second springs 49 is connected to a clamping block 33, and one end of the two clamping blocks 33 is respectively plugged into one end of the second spring 49, and a second spring slot 48 is provided on one side of the two clamping blocks 33, and one end of the two second springs 49 is fixedly connected to the second spring slot 48, and the third rack 46 is fixedly installed on the upper ends of the two clamping blocks 33, and the second rack 32 is fixedly installed on the inner sides of the second plug-in slots 28.

[0037] The positions of the two insertion slots 28 correspond to the right-hand clamping jaw and the left-hand clamping jaw respectively.

[0038] like Figure 1 - Figure 7 As shown, the output end of the control panel 14 is electrically connected to the input ends of the vacuum cleaner 9, the first motor 10, the second motor 19, the first hydraulic cylinder 20, the third motor 36, the second hydraulic cylinder 38, and the third hydraulic cylinder 44.

[0039] It should be noted that, when in use, first, install the base plate 1 in the designated position, connect the external power supply through the control panel 14, and then control the third motor 36 to rotate the fourth gear 35 through the control panel 14. Since the fourth gear 35 is engaged with the first rack 16, the third motor 36 rotates the fourth gear 35 to drive the second slider 34 connected to the third motor 36 and the components on the second slider 34 to move along the guide rail 15. After adjusting the second slider 34 to a suitable position, the feed hopper 41 is replenished with materials, and then the second motor 19 is controlled to rotate the first gear 18. Since the first gear 18 is engaged with the first rack 16, the second motor 19 rotates the first gear 18 to drive the first slider 17 connected to the second motor 19 and the components on the first slider 17 to move along the guide rail 15. After adjusting the first slider 17 to above the diamond barrel 4, the first hydraulic cylinder 20 installed on the first fixed plate 50 is controlled to drive the first telescopic rod 21 to move the mounting box 22 up and down, so that the right-hand clamp under the mounting box 22 The claw 25 and the left-hand clamping claw 26 are adjusted to a suitable position above the feed cover 5, and then the second gear 27 is driven to rotate by the motor in the mounting box 22, so that the right-hand rack 23 engaged with the second gear 27 moves to the right, and the left-hand rack 24 moves to the left, so that the right-hand clamping claw 25 and the left-hand clamping claw 26 are tightened and clamped on the abutment block 30 of the feed cover 5, and the first spring 29 in the first spring groove 47 connected to the abutment block 30 is squeezed and contracts into the first spring groove 47, and the abutment block 30 is moved. The second rack 32 fixed under the abutment block 30 is driven. When the second rack 32 moves, the meshed third gear 31 is rotated, so that the third rack 46 on the clamping block 33, which is meshed with the third gear 31, drives the clamping block 33 to move. At this time, the squeezed second spring 49 will shrink into the second spring groove 48, so that the clamping block 33 is disengaged from the clamping groove on the feed port 52. Then, the first telescopic rod 21 is controlled to shrink so that the right clamping jaw 25 and the left clamping jaw 26 clamp the feed cover 5, thereby realizing automatic opening of the cover;

[0040] Next, the control panel 14 is controlled to rotate the fourth gear 35 through the third motor 36, driving the second slider 34 to move on the guide rail 15 until the second slider 34 is adjusted to above the feed port 52, and then the control panel 14 controls the second hydraulic cylinder 38 on the second fixed plate 37 to adjust the second telescopic rod 39 to lower the second telescopic rod 39. The second telescopic rod 39 lowers the feed hopper 41 installed on the third fixed plate 40 to a suitable position, and the third telescopic rod 45 is extended by controlling the third hydraulic cylinder 44. The third telescopic rod 45 pushes out the L-shaped baffle 43. At this time, the metal powder in the feed hopper 41 falls under the action of gravity through the automatic feed port 42 into the diamond barrel 4. When the required weight of material is placed inside the diamond barrel 4, the L-shaped baffle 43 can be retracted to stop the material discharge. When automatic loading is realized and the automatic loading is completed, the reverse operation can be performed to achieve reset.

[0041] Next, adjust the first slider 17 to above the feed port 52, control the first hydraulic cylinder 20 to lower the first telescopic rod 21 to a suitable position, rotate the second gear 27 to make the right rack 23 and the left rack 24 expand the right clamping jaw 25 and the left clamping jaw 26 to loosen the feed cover 5, at this time, the first spring 29 connected to the abutment block 30 inside the plug-in slot 28 and the second spring 49 connected to the clamping block 33 will rebound and reset due to the loss of pressure of the abutment block 30, so that the clamping block 33 is re-engaged in the clamping slot of the feed port 52, then retract the first telescopic rod 21, and then move the second gear 27 to the right rack 23 and the left rack 24 to expand the right clamping jaw 25 and the left clamping jaw 26 to loosen the feed cover 5. A slider 17 is adjusted to the side, and the first motor 10 is started to operate so that the rotating shaft 3 drives the diamond-shaped barrel 4 to rotate along the axis. Several blades 12 installed on the internal blade rack 11 can further quickly break up the metal powder during the rotation. After the metal powder is fully mixed, the vacuum cleaner 9 is controlled to be turned on, and then the staff opens the discharge cover 6 of the discharge port 53. At this time, the diffused metal dust will be sucked into the connecting pipe 8 by the dust removal pipe 7, and collected by the other end of the vacuum cleaner 9 for recycling. After the discharge is completed, the mixed metal powder will be shipped to the subsequent processing steps.
