[0026] Furthermore, the driving device 3 drives the transmission belt 4 to drive the cylinder 2 to rotate, and cooperates with the grinding balls 8 in the cylinder 2 to grind the material.

[0027] Furthermore, a feed inlet is arranged at intervals on the top of the cylinder 2, and a discharge outlet is arranged at intervals on the bottom of the cylinder 2.

[0028] Furthermore, an inner cylinder 5 is arranged inside the cylinder body 2, the outer diameter of the inner cylinder 5 is smaller than the inner diameter of the cylinder body 2, and the inner cylinder 5 and the cylinder body 2 are arranged at an interval, and the two ends of the inner cylinder 5 are fixedly connected to the two ends of the cylinder body 2 respectively.

[0029] Furthermore, the interior of the cylinder 2 is divided into a grinding area and a material collection area by the inner cylinder 5. The inner side of the inner cylinder 5 is the grinding area, and the area between the inner cylinder 5 and the cylinder 2 is the material collection area.

[0030] Furthermore, a connecting tube 6 is fixedly installed at intervals on the inner side of the cylinder 2. The position of the connecting tube 6 corresponds to the position of the feed port. The connecting tube 6 is arranged along the radial direction of the cylinder 2. The two ends of the connecting tube 6 are fixedly connected to the cylinder 2 and the inner cylinder 5 respectively. One end of the connecting tube 6 is connected to the feed port, and the other end is connected to the inner cavity of the inner cylinder 5.

[0031] Furthermore, a filter plate 7 is arranged inside the inner cylinder 5 , and a plurality of filter plates 7 are arranged at intervals around the inner cylinder 5 . The filter plates 7 are arc-shaped filter plates protruding toward the inner side of the inner cylinder 5 .

[0032] In this embodiment, the inwardly protruding filter plate 7 can effectively prevent the grinding material from sinking outwards due to compression or gravity and causing the filter plate 7 to aggregate during the rotary grinding operation.

[0033] Furthermore, a permeation groove 9 is provided on the side wall of the inner tube 5 at a position corresponding to the filter plate 7 . The permeation groove 9 is a stepped slot. The diameter of the inner end of the permeation groove 9 is greater than the diameter of the outer end. The outer end of the permeation groove 9 is adapted to the shape and size of the filter plate 7 .

[0034] Furthermore, an auxiliary component for supporting the filter plate 7 and driving the filter plate 7 to perform elastic adjustment is provided inside the infiltration groove 9, and the auxiliary component includes a support plate 10, a support column 11, a limit plate 12, an elastic force limiter 13, a fixing ring 14 and a material limit plate 15.

[0035] Furthermore, two groups of support plates 10 are spaced apart on one side of the filter plate 7 close to the infiltration groove 9. The support plates 10 are arc-shaped plates, and the curvature of the support plates 10 matches the inner curvature of the filter plate 7. The outer side wall of the support plate 10 and the inner side wall of the filter plate 7 fit each other.

[0036] Furthermore, a limiting plate 12 is provided on one side of the two groups of support plates 10 away from the filter plate 7, the size of the limiting plate 12 is adapted to the size of the large end of the infiltration groove 9, a support column 11 is fixedly installed on the bottom of the support plate 10, and one end of the support column 11 away from the support plate 10 is fixedly installed on the limiting plate 12, the limiting plate 12 is arranged in the large end of the infiltration groove 9, an elastic limiting member 13 is provided between the limiting plate 12 and the shoulder of the infiltration groove 9, and the elastic limiting member 13 has two symmetrically arranged on both sides of the limiting plate 12.

[0037] In this embodiment, the support plate 10 is provided through arc-shaped adaptation, so that the filter plate 7 can be effectively supported and limited, and the filter plate 7 is prevented from being deformed and overloaded due to excessive pressure.

[0038] In this embodiment, by providing an elastic limiter 13, the filter plate 7 can be elastically adjusted to a small extent when under pressure, so that the fine materials that meet the specifications in the contact area can be effectively elastically filtered, effectively avoiding blockage. At the same time, the processed materials that do not meet the specifications can be effectively rebounded, and the processed materials can be re-entered into the grinding area through the elastic force, avoiding the clogging of the filter holes by the processed materials that do not meet the specifications. At the same time, the rebound force allows the processed materials to effectively contact the grinding balls 8 that are moving inside the cylinder 2, so that the processed materials that do not meet the specifications can be better re-grinded, thereby improving the grinding efficiency.

[0039] Furthermore, the side of the limiting plate 12 close to the supporting plate 10 is a concave arc surface, and a material guide hole 16 is opened in the middle of the limiting plate 12. The limiting plate 12 is arc-shaped so that the material can move in the direction of the material guide hole 16, and the material guide hole 16 runs through the limiting plate 12.

[0040] In this embodiment, the concave limit plate 12 can effectively transfer the aggregate on the limit plate 12 to the guide hole 16 through the arc surface, and then discharge it into the aggregate area, which can effectively avoid the occurrence of material accumulation.

[0041] Furthermore, a fixing ring 14 is fixedly installed at a position corresponding to the material guide hole 16 on the side of the limiting plate 12 away from the support plate 10. The fixing ring 14 is annular, and the inner diameter of the fixing ring 14 is adapted to the inner diameter of the material guide hole 16. A limiting plate 15 is fixedly installed on the side of the fixing ring 14 away from the limiting plate 12. The end of the limiting plate 15 away from the fixing ring 14 is inclined toward the direction close to the axis of the fixing ring 14. Several limiting plates 15 are arranged around the fixing ring 14. Each limiting plate 15 is enclosed in a funnel shape. The limiting plate 15 can be deformed in a dispersed manner when subjected to pressure. The limiting plate 15 is made of elastic material.

[0042] In this embodiment, the funnel-shaped limiting plate 15 can effectively guide the material out of the grinding area while preventing the material in the gathering area from entering the grinding area.

[0043] Furthermore, two groups of fixing rings 14 are arranged side by side, and an annular limiting groove 17 is opened on the adjacent side of the two groups of fixing rings 14. A plurality of limiting balls 18 are slidably installed in each limiting groove 17. The limiting balls 18 in the two limiting grooves 17 correspond to each other one by one, and the corresponding limiting balls 18 in the two limiting grooves 17 are fixedly connected by a connecting rod 19. One group of fixing rings 14 is fixed to the limiting plate 12, and the other group of fixing rings 14 is fixed to the limiting plate 15.

[0044] In this embodiment, the two groups of fixed rings 14 can rotate relative to each other through the limit groove 17, the limit ball 18 and the connecting rod 19. When the limiting plate 15 is subjected to pressure impact, the limiting plate 15 is rotated under the action of the fixed ring 14 through the impact force, thereby offsetting the excessive pressure impact and reducing the situation where the limiting plate 15 cannot work effectively due to the pressure impact. Through the multiple groups of rotatable limiting plates 15, the material is diffused and transmitted to the inside of the collecting trough under the action of centrifugal force, thereby effectively avoiding the accumulation of material powder.

[0045] The working principle and use process of the utility model are as follows: when in use, the material to be processed is placed inside the cylinder 2 through the feed port, and the drive belt 4 is started by the driving device 3 to drive the cylinder 2 to rotate, so that the grinding balls 8 inside the cylinder 2 grind the material under the action of the inertia and centrifugal force generated by the rotation. When the material is ground to the specified specifications, it is screened and transmitted to the aggregate area through the filter plate 7. When the grinding operation is completed, the processed material inside the aggregate area is discharged by opening the discharge port, thereby completing the operation.

[0046] The inner cylinder 5 separates the interior of the cylinder 2 into a grinding area and an aggregate area. At the same time, the raised filter plate 7 is used to limit the finished ground material so that it can be effectively transferred to the designated position during grinding. At the same time, it can effectively avoid over-grinding of the ground material that has met the specifications, greatly reducing the occurrence of grinding interference with the unground ground material.

[0047] By setting the elastic limiter 13, the filter plate 7 can be adjusted elastically in a small range when under pressure, so that the fine materials that meet the specifications in the contact area can be effectively elastically filtered, and blockage can be effectively avoided. At the same time, the processed materials that do not meet the specifications can be effectively rebounded, and the processed materials can be re-entered into the grinding area through the elastic force, so as to avoid the clogging of the filter holes by the processed materials that do not meet the specifications. At the same time, the rebound force allows the processed materials to effectively contact the grinding balls 8 that are moving inside the cylinder 2, so that the processed materials that do not meet the specifications can be better re-grinded, thereby improving the grinding efficiency.

[0048] By separating the grinding area and the aggregation area, the grinding material entering the aggregation area can follow the cylinder 2 and rotate along the wall inside the aggregation area before the operation is completed, so that the grinding material can be effectively spread and diffused, avoiding the occurrence of material accumulation and blockage, and reducing the occurrence of aggregation of the ground grinding material.

[0049] The above is only the preferred embodiment of the utility model, and does not limit the utility model in other forms. Any technician familiar with the profession may use the technical content disclosed above to change or modify it into an equivalent embodiment with equivalent changes. However, any simple modification, equivalent change and modification made to the above embodiment based on the technical essence of the utility model without departing from the technical solution of the utility model still belongs to the protection scope of the technical solution of the utility model.
