[0034] 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.

[0035] Reference Figure 1 , Figure 3 and Figure 4 This utility model provides an embodiment of an automatic feeding device for ultrafine powder, comprising a material hopper 1, with a feed inlet 18 at the top of the hopper 1 to facilitate feeding. A first motor 3 is fixedly connected to the middle of the top of the hopper 1. The output end of the first motor 3 passes through the hopper 1 and is fixedly connected to a rotating rod 4. Multiple stirring blades 5 are fixedly connected to the outer side of the rotating rod 4. Starting the first motor 3 can drive the rotating rod 4 and the stirring blades 5 to rotate, mixing and breaking up clumps of material. The bottom end of the rotating rod 4 passes through the hopper 1 and is fixedly connected to a rotating disk 6. The top of the rotating disk 6... The material barrel 1 has a material distribution port 7 and a first discharge port 8 at the bottom. When the rotating rod 4 rotates, it can drive the rotating disk 6 and the material distribution port 7 on it to rotate. A support platform 11 is fixedly connected to the bottom right side of the material barrel 1. A blower 9 is fixedly connected to the top of the support platform 11. The output end of the blower 9 is connected to the air inlet pipe 10. The left side of the air inlet pipe 10 is connected to the material barrel 1. When the blower 9 is started, it can blow air into the device through the air inlet pipe 10 to reduce the probability of powder adhesion and improve the mixing effect. A lifting mechanism 2 is set at the bottom of the material barrel 1. The lifting mechanism 2 is used to support and move the device.

[0036] Specifically, material is added into the material barrel 1 through the feed inlet 18, and the first motor 3 is started at the same time, driving the rotating rod 4 and its stirring blades 5 to start rotating. The rotation of the stirring blades 5 can effectively break up the lumps inside the material and fully mix the material. At the same time, the blower 9 on the support platform 11 is started, and external air is drawn into the material barrel 1 through the air inlet pipe 10 to ensure that the material is kept in a dusty state and to avoid adhesion. During this process, the rotation of the rotating rod 4 will also drive the rotating disk 6 to rotate together. As the rotating disk 6 rotates, the dispensing port 7 on it will intersect or overlap with the first discharge port 8 at the bottom of the material barrel 1. Thus, by controlling the rotation speed of the rotating rod 4, the material is quantitatively and batched and discharged through the first discharge port 8.

[0037] Reference Figure 2 and Figure 5 The lifting mechanism 2 includes telescopic leg housings 207 and belts 206. Multiple telescopic leg housings 207 are fixedly connected to the bottom perimeter of the material hopper 1. Rotating wheels 205 are rotatably connected to the top outer side of each telescopic leg housing 207. Multiple rotating wheels 205 are connected to each other via corresponding belts 206. The belts 206 drive the rotating wheels 205 to rotate synchronously. A first bevel gear 201 is fixedly connected to the outer side of each rotating wheel 205, passing through the telescopic leg housing 207. When the rotating wheel 205 rotates, it synchronously drives the first bevel gear 201... A bevel gear 201 rotates, and a second bevel gear 202 is rotatably connected to the top inner side of the telescopic leg housing 207. The second bevel gear 202 meshes with the first bevel gear 201. A threaded rod 203 is fixedly connected to the bottom of the second bevel gear 202. As the first bevel gear 201 rotates, it will drive the second bevel gear 202 and its threaded rod 203 to rotate through the meshing connection. A lifting leg 204 is threadedly connected to the outer side of the threaded rod 203. The lifting leg 204 can be moved when the threaded rod 203 is rotated.

[0038] Specifically, through the transmission mechanism of belt 206, when one side of the rotating wheel 205 is turned, it can synchronously drive the rotating wheels 205 in other positions to rotate together. As the rotating wheel 205 rotates, it will further drive the first bevel gear 201 to rotate. The rotation of the first bevel gear 201 will synchronously drive the second bevel gear 202 meshing with it to rotate, which in turn drives the threaded rod 203 on the second bevel gear 202 to rotate together. At this time, the rotation of the threaded rod 203 will drive the lifting leg 204 on its outer side to move up and down. Through the up and down movement of the lifting leg 204, the height position of the device can be flexibly adjusted and controlled.

[0039] Reference Figure 1 , Figure 2 and Figure 4Multiple handrails 20 are fixedly connected to the side of the material bucket 1, and protective sleeves 21 are fixedly connected to the outer side of each handrail 20. The handrails 20 and protective sleeves 21 facilitate the gripping and handling of the device. A controller 19 is fixedly connected to the front of the material bucket 1. The controller 19 is electrically connected to the first motor 3, the blower 9 and the second motor 15 respectively. A storage box 12 is fixedly connected to the bottom of the material bucket 1. A second discharge port 13 is opened at the bottom of the storage box 12. The controller 19 can control the switching of the first motor 3, the blower 9 and the second motor 15.

[0040] Specifically, the handle 20 facilitates the gripping and handling of the device, and the protective cover 21 on it enhances the comfort of gripping the device. The controller 19 can control the starting and running power of the first motor 3, the blower 9, and the second motor 15 respectively. The storage bin 12 can store the material discharged from the first discharge port 8 to prevent dust. At the same time, the rotation of the rotating disk 6 will cause the distributing port 7 on it to intersect and stagger with the second discharge port 13, thereby improving the quantitative and batch feeding effect and reducing dust during discharge.

[0041] Reference Figure 1 , Figure 5 and Figure 6 The bottom of the second discharge port 13 is connected to the discharge pipe 14, and the bottom of the discharge pipe 14 is connected to the discharge pipe 16. The right side of the discharge pipe 16 is fixedly connected to the second motor 15. The output end of the second motor 15 passes through the discharge pipe 16 and is fixedly connected to the auger 17. The material discharged by the device will be sent into the discharge pipe 16 through the discharge pipe 14. At this time, the second motor 15 is started to drive the auger 17 to rotate so that the material can be discharged evenly. The upper outer side of the telescopic leg shell 207 is fixedly connected to the dust cover 23. Multiple telescopic leg shells 207 are fixedly connected by corresponding dust covers 23. The dust covers 23 can protect the rotating wheel 205 and the belt 206.

[0042] Specifically, the material discharged from the second discharge port 13 can be received through the feeding pipe 14 and fed into the discharge pipe 16. Then, the second motor 15 is started to drive the auger 17 to rotate, so that the material is discharged evenly and orderly. The quantitative feeding step can prevent the auger 17 from clogging. The dust cover 23 can protect the transmission relationship between the rotating wheel 205 and the belt 206 and prevent impurities from interfering.

[0043] Reference Figure 2 and Figure 5A handle 24 is rotatably connected to the outside of the dust cover 23. The handle 24 passes through the dust cover 23 and is fixedly connected to the first bevel gear 201. Rotating the handle 24 can drive the first bevel gear 201 to rotate. A connecting rod 25 is fixedly connected to the outside of the telescopic leg shell 207. Multiple telescopic leg shells 207 are fixedly connected to each other through corresponding connecting rods 25. Multiple moving wheels 22 are rotatably connected to the bottom of each of the multiple connecting rods 25. When the lifting leg 204 is retracted, the moving wheels 22 will contact the ground to facilitate the movement of the device.

[0044] Specifically, by rotating the handle 24, the first bevel gear 201 can be rotated synchronously for easy operation. Through the connecting rod 25 and the rotating moving wheel 22 on it, the moving wheel 22 can be grounded when the lifting leg 204 of the lifting mechanism 2 is fully retracted. At this time, the device can be moved by the rotation of the moving wheel 22 with the ground.

[0045] Working principle: First, material is added to the front part of the material barrel 1 through the feed inlet 18, and at the same time, the first motor 3 is started to drive the rotating rod 4 and the stirring blade 5 on it to rotate. The rotation of the stirring blade 5 breaks up the lumps inside the material and mixes the material. At the same time, the blower 9 on the support platform 11 is started to draw external air into the material barrel 1 through the air inlet pipe 10, so that the material is always kept in a dusty state to prevent it from adhering. At this time, as the rotating rod 4 rotates, it also drives the rotating disk 6 to rotate. As the rotating disk 6 rotates, the distributing port 7 on it will intersect and cross with the first discharge port 8 at the bottom of the material barrel 1. When the material is discharged through the first discharge port 8, the rotation speed of the rotating rod 4 determines the quantity and batch of material discharge.

[0046] Furthermore, through the transmission of the belt 206, when the rotating wheel 205 on one side is turned, it can synchronously drive the rotating wheels 205 in other positions to rotate synchronously. As the rotating wheel 205 rotates, it synchronously drives the first bevel gear 201 to rotate, so as to synchronously drive the second bevel gear 202 meshing with it and the threaded rod 203 on it to rotate. At this time, rotating the threaded rod 203 will drive the lifting leg 204 on its outer side to move up and down. In this way, the height position of the device can be adjusted and controlled by the up and down movement of the lifting leg 204.

[0047] Finally, it should be noted that the above description is only a preferred embodiment of the present utility model and is not intended to limit the present utility model. Although the present utility model has been described in detail with reference to the foregoing embodiments, those skilled in the art can still modify the technical solutions described in the foregoing embodiments or make equivalent substitutions for some of the technical features. Any modifications, equivalent substitutions, improvements, etc., made within the spirit and principles of the present utility model should be included within the protection scope of the present utility model.
