DETAILED DESCRIPTION

[0030] In order to make the technical means, creative features, objectives and effects achieved by the present invention easier to understand, the present invention is further described below in conjunction with specific implementation methods.

[0031] In order to facilitate the addition of auxiliary aggregate mechanisms, improve the aggregate effect of materials, reduce resource waste, and thus improve the use effect, such as Figure 1-3 As shown, the grinding mill structure described in the present invention includes a frame 1, a collection trough 3 and a feeding assembly 7.

At the same time, the material blocking component 5 can also play an auxiliary screening effect, which can increase the functionality and practicality of the crusher.

[0034] The outer surface of the aggregate trough 3 is connected to the servo motor via bolts, and the servo motor is connected to the rotating shaft 503 via a driving shaft.

[0035] In order to improve the quality of material grinding and pulverization, for example, Figure 1 、 Figure 5As shown, the utility model also includes that the feeding component 7 includes a feeding port 701, and a cover plate 702 is provided on the outside of the feeding port 701, one end of the cover plate 702 is connected to the rotating shaft 703 by a bolt, and the cover plate 702 is rotatably connected to the top of the feeding port 701 through the rotating shaft 703, and a coil spring 704 is provided on the outer periphery of the rotating shaft 703, and one end of the coil spring 704 is connected to the rotating shaft 703 by welding, and the other end of the coil spring 704 is connected to the feeding port 701 through a slot.

[0036] During use, an auxiliary sealing protection mechanism for feeding can be added through the feed port 701, the cover plate 702, the rotating shaft 703, and the coil spring 704, and the elastic deformation is used to drive the cover plate 702 to rotate for auxiliary sealing protection, thereby preventing external dust and material dust from entering and exiting the grinding mill, thereby affecting the material quality and reducing the waste of material resources.

[0037] For example, Figure 1 、 Figure 2 As shown, the utility model also includes that the bottom of the grinding chamber 2 is connected to the barrel 204 by bolts, and the discharge end of the barrel 204 is connected to the collection trough 3, the collection trough 3 includes an air outlet 301, and the air inlet end of the vacuum pump 4 is connected to the air outlet 301 through a pipeline, and a microporous filter 302 is provided on one side of the air outlet 301 in the collection trough 3.

[0038] During use, the ground powdered material is conveniently introduced into the aggregate trough 3 through the barrel 204 for auxiliary aggregate recovery. The air outlet 301 and the microporous filter 302 are convenient for connecting to a vacuum pump for use, and the outlet air is filtered at the same time.

[0039] For example, Figure 5 As shown, the present invention further includes that an air inlet 705 is opened on the surface of the feed port 701 , and the air inlet 705 is connected to the feed port 701 , and a filter screen 706 is provided in the air inlet 705 .

[0040] When in use, the air entering the pulverizer is filtered in advance through the air inlet 705 and the filter screen 706 , and a one-way valve is provided at the air outlet end of the air inlet 705 .

[0041] For example, Figure 4 As shown, the present invention also includes that the material guiding assembly 6 includes a sleeve 601, a rotating rod 602 is rotatably connected inside the sleeve 601, the outer periphery of the rotating rod 602 is connected to the spiral blade 603 by bolts, the bottom of the sleeve 601 is connected to the drive motor 604 by bolts, and a discharge port 605 is opened on the outer side of the sleeve 601.

[0042] When in use, the sleeve 601, the rotating rod 602, the spiral blade 603, and the driving motor 604 are used to facilitate the use of the spiral conveying structure to deliver the powdered material for auxiliary discharging operation, and the discharge port 605 includes a sealing plug.

[0043] For example, Figure 1 As shown, the present invention also includes that a grinding shaft 101 is installed in the frame 1 through a bearing seat, and the grinding shaft 101 passes through the grinding chamber 2, and a grinding hammer 201 is connected to the periphery of the grinding shaft 101 in the grinding chamber 2 through bolts, and a screen 202 is provided on the periphery of the grinding hammer 201 in the grinding chamber 2, and a flushing port 203 is opened on the outside of the grinding chamber 2.

[0047] When the present invention is in use, the operator first feeds the material into the shell 1 from the feed port 701 and the material falls into the grinding chamber 2. At the same time, the elastic deformation of the coil spring 704 drives the rotating shaft 703 and the cover plate 702 to flip to the outside of the feed port 701 to cover and protect it. This can prevent dust and material from entering and exiting during the operation of the grinding mill, thereby reducing the pollution of dust to the material, and is also conducive to reducing resource waste and environmental pollution. Then, the frequency conversion motor 8 is manually turned on to drive the grinding shaft 101 and the grinding hammer 201 to rotate, and the screen 202 is used to grind and crush the material.

[0048] While the material is being ground and crushed, the vacuum pump 4 can be manually turned on at regular intervals. The negative pressure generated by the suction of the vacuum pump 4 can suck the air in the grinding chamber 2 together with the ground and crushed powdered material into the aggregate trough 3, and the air is screened through the sieve holes 502 of the rotating disk 501 of the material blocking component 5 and then falls, completing the auxiliary aggregation operation. At the same time, the setting of sieve holes 502 of different sizes can be used to achieve the effect of auxiliary screening of materials. The structure is simple and easy to operate, and the use is more convenient and flexible. It can also reduce the waste of resources caused by the residue of materials in the grinder and improve the use effect. Finally, the drive motor 604 can be manually turned on to drive the rotating rod 602 to rotate, and the spiral blade 603 can be used to send the material out from the opened discharge port 605 for auxiliary discharge.
