Obviously, the embodiments described are only part of the embodiments of the present invention, not all of the embodiments. Based on the embodiments of the present invention, all other embodiments obtained by ordinary technicians in this field without making creative efforts are within the scope of protection of the present invention.

[0028] See Figure 1-Figure 5 As shown, it includes a grinding chamber 1, a powder grinding structure is provided in the grinding chamber 1, a material discharge structure is provided in the middle of the bottom of the grinding chamber 1, and several support legs 21 are connected to the outer side of the bottom of the grinding chamber 1; a feed trough 2 is provided on the top of the grinding chamber 1, a feed port 3 is opened at the feed trough 2 on the grinding chamber 1, a feed cover 6 and a driving component for driving the feed cover 6 are provided at the feed port 3 on the grinding chamber 1; a support block 23 is installed at the bottom of each supporting leg 21, a vibration reduction structure is provided in the support block 23, and a sound insulation layer 28 is sandwiched between the grinding chamber 1 and the feed cover 6.

[0029] See Figure 1-Figure 2As shown, the driving assembly includes a cover slide 4 opened at the feed port 3 at the top of the grinding bin 1, and several spring grooves 8 are opened on the rear side of the cover slide 4. A guide groove is opened at the rear end of each spring groove 8. A feed cover 6 is slidably installed in the cover slide 4, and a plurality of guide slide rods 7 are connected to the rear end of the feed cover 6. The guide slide rods 7 are all slidably arranged in the guide grooves, and a spring 9 is sleeved on the guide slide rod 7. The spring 9 is arranged in the spring groove 8. A rope groove 13 parallel to the guide slide rod 7 is opened in the grinding bin 1, and a rotating groove 10 connected to it is opened at the rear end of the rope groove 13. A rotating shaft 11 is rotatably installed in the rotating groove 10, and a door opening motor 12 is provided at one end of the rotating shaft 11. The rotating rod of the door opening motor 12 is connected to the rotating shaft 11, and a door opening steel wire 14 is connected to the rear end of the feed cover 6. One end of the door opening steel wire 14 passes through the rope groove 13 and is connected to the rotating shaft 11; a protective cover 20 is provided on the upper cover of the driving assembly.

[0030] As an optimization solution of the present invention, a spring 9 is provided to push the feed cover 6 so that the feed cover 6 slides forward along the cover slide groove 4 to close the door, and the door opening motor 12 drives the rotating shaft 11 to rotate, and the door opening wire 14 is reeled in. The feed cover 6 can be pulled backward by the door opening wire 14, and the spring 9 is compressed at the same time to open the door. In the process of opening and closing the door, the guide slide rod 7 can guide the feed cover 6 to ensure that the moving direction of the feed cover 6 is accurate.

[0031] See Figures 1-6 As shown, a blanking chute 5 connected to the grinding bin 1 is opened downward at the front end of the cover chute 4, and inclined grooves 16 are opened on both sides of the front end of the feed cover 6 located in the cover chute 4. The width of the inclined groove 16 is the same as the width of the cover chute 4, and rubber strips 19 are respectively installed at the upper and lower ends of the inclined groove 16 to fit the upper and lower sides of the cover chute 4.

[0032] As an optimization solution of the present invention, when the door is closed, the feed cover 6 moves forward, which can push the material remaining in the cover chute 4 forward. The inclined groove 16 can ensure that the residual material will gradually move downward during the movement until it reaches the drop chute 5, and can fall into the grinding bin 1 under the action of gravity, preventing the residual material from agglomerating or clogging in the cover chute 4. The rubber strip 19 can ensure that the residual material will not enter the upper and lower sides of the feed cover 6 at the cover chute 4 when pushing the material.

[0033] See Figure 1-Figure 7 As shown, the vibration reduction structure includes a movable groove 25 opened on the upper side of the support block 23, and the bottom of the support leg 21 is connected to the connecting block 22. The cross-sectional dimension of the movable groove 25 is larger than the cross-sectional dimension of the connecting block 22. The connecting block 22 is arranged in the movable groove 25. A plurality of supporting springs 26 are provided at the bottom end of the connecting block 22. Buffer pads 27 are provided between the surrounding areas of the connecting block 22 and the inner wall of the movable groove 25. A vibration reduction pad 24 is provided at the bottom of the support block 23.

[0034] As an optimization solution of the present invention, a support spring 26 is provided. While supporting the upper structure, the elasticity of the support spring 26 itself can also absorb the vibration transmitted from above, reducing the generation of noise. At the same time, the buffer pad 27 elastically squeezes the support leg 21 inward from the side, which can absorb lateral vibrations, thereby greatly reducing noise.

[0035] See Figures 1-6 As shown, a rubber strip 15 is provided at the upper and lower edges of the cover slide 4 on the side of the feed port 3 away from the blanking chute 5. The width of the rubber strip 15 is equal to the width of the feed port 3, and the top and bottom surfaces of the rubber strip 15 are respectively in contact with the upper and lower surfaces of the feed cover 6.

[0036] As an optimization solution of the present invention, a rubber strip 15 is provided to scrape off the material remaining on the surface of the feed cover 6 when the door is opened or closed, thereby preventing the material from entering the cover chute 4 as the door is closed.

[0037] See Figures 1-6 As shown, pulley grooves 17 are respectively provided on both sides of the feed cover 6 , and a plurality of rollers 18 are provided in the pulley grooves 17 on the feed cover 6 .

[0038] As an optimization solution of the present invention, a roller 18 is provided to reduce the friction on the surface of the feed cover 6 when the door is opened and closed, thereby extending its service life.

[0039] See Figure 1 As shown, several support blocks 23 are connected in sequence through connecting rods 29 , and the number of connecting rods 29 is one less than the number of support blocks 23 .

[0040] As an optimization solution of the present invention, a connecting rod 29 is provided to connect the plurality of support blocks 23 into a whole, thereby enhancing the stability of the support and reserving a gap for the placement of the discharge equipment.

[0041] The use process of this utility model:

[0042] First, install the mill in place and power it on. When loading is required, start the door opening motor 12, use the rotating shaft 11 to reel in the door opening wire 14, pull the feed cover 6 to open the door, add the materials required for production through the feed port 3, and control the door opening motor 12 to reverse. The door opening wire 14 is gradually loosened, and the spring 9 gradually rebounds and pushes the feed cover 6 forward to close the door, thereby starting the grinding mechanism to start operation;

[0043] During operation, the feed cover 6 seals the feed port 3, thereby reducing the transmission of vibrations through the air. At the same time, the sound insulation layer 28 absorbs the noise, reducing the noise transmitted from the mill to the surrounding area. The vibration reduction structure also absorbs the noise transmitted downward. The multiple modes work in combination to reduce the noise generation.

[0044] After processing is completed, open the discharge structure to discharge the powder.

[0045] It should be understood that the above-described specific embodiments of the present invention are merely illustrative of or explanation of the principles of the present invention and do not constitute limitations of the present invention. Therefore, any modifications, equivalent substitutions, improvements, etc. made without departing from the spirit and scope of the present invention shall be included within the scope of protection of the present invention.
