Therefore, the terms describing the positional relationship in the drawings are only used for illustrative purposes and cannot be understood as limitations on this patent. For ordinary technicians in this field, the specific meanings of the above terms can be understood according to specific circumstances.

[0039] The implementation of the present utility model is described in detail below in conjunction with specific embodiments.

[0040] Reference Figure 1 , Figure 2 , Figure 3 As shown, a preferred embodiment of the utility model is provided.

[0041] In a first aspect, the utility model provides a sliced ​​grain grinding sand cylinder, which is used to be installed on a rotating device, and the rotating device drives a sliced ​​drum 1 for grain grinding to rotate to grind the grain, including:

[0042] Cylinder 1 and several sand sheets 2.

[0043] Specifically, a first fixing structure 10 is provided on the cylinder 1, and a second fixing structure 20 is provided on the sand sheet 2. The sand sheet 2 is detachably fixedly connected to the cylinder 1 through the first fixing structure 10 and the second fixing structure 20, and a plurality of sand sheets 2 are arranged around the cylinder 1; more specifically, the sand sheet 2 has an outer surface 3 facing away from the direction of the cylinder, and a hard abrasive is provided on the outer surface 3 for grinding grains.

[0044] It is understandable that the fixed connection between the sand piece 2 and the cylinder 1 can be disassembled, that is, the sand piece 2 fixed on the cylinder 1 can be replaced. When the hard abrasive on a sand piece 2 is damaged, the sand piece 2 can be replaced with a new one separately.

[0045] The utility model provides a sliced ​​grain grinding sand cylinder, which has the following beneficial effects:

[0046] 1. In the utility model, a plurality of sand sheets 2 are detachably fixed around the cylinder 1. When the hard abrasive on a certain sand sheet 2 is damaged, the sand sheet 2 can be replaced individually without replacing the cylinder 1 as a whole. This solves the problem in the prior art that when a part of the hard abrasive on the integrated grinding sand cylinder 1 is damaged, the entire grinding sand cylinder 1 needs to be replaced, resulting in inconvenience in replacement.

[0047] 2. In the utility model, a plurality of sand sheets 2 are arranged around the cylinder 1. The sand sheets 2 can be replaced according to the types of grains to grind different types of grains. When it is necessary to grind the grains with different precisions, it can be achieved by replacing the sand sheets 2, which solves the problem in the prior art that the one-piece cylinder 1 cannot grind the grains with different precisions.

[0048] 3. In the utility model, the sanding sheet 2 includes a main body 21, an upper fixing portion 22 and a lower fixing portion 23. The main body 21 is used for grinding grains, and the upper fixing portion 22 and the lower fixing portion 23 are used to fix the sanding sheet 2 on the cylinder 1. Since the upper fixing portion 22 and the lower fixing portion 23 are both "L"-shaped, the upper fixing portion 22 and the lower fixing portion 23 will not collide with the grains, thereby reducing the broken rice rate of the grains and improving the service life of the sanding sheet 2.

[0049] In some embodiments, the first fixing structure 10 includes a first positioning hole 101 and a first fixing hole 102 , and the second fixing structure 20 includes a second positioning hole 201 and a second fixing hole 202 .

[0050] Specifically, the relative position between the second positioning hole 201 and the second fixing hole 202 is consistent with the relative position between the first positioning hole 101 and the first fixing hole 102; the first positioning hole 101 and the second positioning hole 201 are used to set the positioning pin, and the first fixing hole 102 and the second fixing hole 202 are used to set the screw.

[0051] It can be understood that when the second positioning hole 201 on the sand sheet 2 is docked with the first positioning hole 101 on the cylinder 1, the second fixing hole 202 on the sand sheet 2 and the first fixing hole 102 on the cylinder 1 will also be docked one by one. At this time, positioning pins can be set in the first positioning hole 101 and the second positioning hole 201, and screws can be set in the first fixing hole 102 and the second fixing hole 202 to fix the sand sheet 2 and the cylinder 1.

[0052] It should be noted that the diameter of the positioning hole used to set the positioning pin is larger than the diameter of the fixing hole used to set the screw, that is, the diameter of the positioning pin is larger than the diameter of the screw. Therefore, the positioning pin can ensure that the sand piece 2 is stably fixed on the cylinder 1, with accurate position and no shaking, to prevent errors caused by fixing only with screws.

[0053] It should be noted that the positioning pin can be pre-set on the cylinder 1 or the sand piece 2. In this case, the structure of the positioning pin is in the shape of a hook. When the sand piece 2 is set, the sand piece can be hung on the cylinder 1 through the positioning pin.

[0054] In some embodiments, the cylinder 1 includes a cylinder shaft 11 , a cylinder wall 12 , an upper flange 13 and a lower flange 14 .

[0055] Specifically, the upper flange 13 has a first mounting hole 15 at the center position, and the upper flange 13 is arranged on the cylinder shaft 11 through the first mounting hole 15. The lower flange 14 has a second mounting hole 16 at the center position, and the lower flange 14 is arranged on the cylinder shaft 11 through the second mounting hole 16; the cylinder wall 12 is sleeved on the upper flange 13 and the lower flange 14, and the upper end and the lower end of the cylinder wall 12 are both provided with a first fixing structure 10.

[0056] It should be noted that fixing rings protruding inwards are respectively provided at the upper and lower ends of the inner side of the cylinder wall 12 , and the upper flange 13 and the lower flange 14 fix the cylinder wall 12 by abutting against the fixing rings.

[0057] In some embodiments, a third fixing structure 17 is disposed on the cylinder shaft 11 .

[0058] Specifically, the third fixing structure 17 is used to fix the cylinder shaft 11 on the rotating device.

[0059] More specifically, the third fixing structure 17 includes a fixing thread 171, a notch portion 172 and a recessed portion 173; the recessed portion 173 is arranged at the top end of the cylindrical shaft 11, and is used for the cylindrical shaft 11 to be fixedly installed on the rotating device, and the fixing thread 171 and the notch portion 172 are arranged at the bottom end of the cylindrical shaft 11, and are used for the cylindrical shaft 11 to be installed on the rotating device to drive the cylindrical shaft 11 to rotate.

[0060] It should be noted that the recessed shape of the recessed portion 173 is cylindrical, and the rotating device is embedded in the recessed portion 173 to fix the cylindrical shaft 11 from the upper and lower ends; the shape of the notch portion 172 is a vertical notch, and the notch portion 172 is used for the cylindrical shaft 11 to be installed on the rotating device. The cylindrical shaft 11 is tightly fitted with the rotating device through the notch portion 172. When the rotating device rotates, the cylindrical shaft 11 will also rotate accordingly; the rotating device is provided with a thread that is fitted with the fixed thread 171. When the cylindrical shaft 11 is set, the cylindrical shaft 11 is rotated to make the fixed thread 171 fit with the thread in the rotating device to achieve a stable connection between the cylindrical shaft 11 and the rotating device.

[0061] In some embodiments, the cross section of the cylinder wall 12 is circular or regular polygonal.

[0062] Specifically, the outer shape of the cylinder wall 12 is cylindrical, and the sand piece 2 is arranged outside the cylinder wall 12 to form a circular shape for grinding grains. In addition, the cross-sectional shape of the cylinder wall 12 can also be a regular polygon, and each side is used for a sand piece 2 to be fixed and installed. Similarly, several combinations can be made into a cylindrical shape to grind grains.

[0063] In some embodiments, the sand sheet 2 includes a main body 21 , an upper fixing portion 22 and a lower fixing portion 23 .

[0064] Specifically, the upper fixing portion 22 and the lower fixing portion 23 are respectively disposed at the upper end and the lower end of the main body 21 ; the second fixing structure 20 is disposed on both the upper fixing portion 22 and the lower fixing portion 23 .

[0065] More specifically, the upper fixing portion 22 includes an upper horizontal plate 221 and an upper vertical plate 222 . The upper horizontal plate 221 is vertically connected to the main body 21 , and the upper vertical plate 222 is vertically connected to the upper horizontal plate 221 . The upper horizontal plate 221 is provided with a second fixing structure 20 .

[0066] More specifically, the lower end fixing portion 23 includes a lower end horizontal plate 231 and a lower end vertical plate 232 . The lower end horizontal plate 231 is vertically connected to the main body 21 , and the lower end vertical plate 232 is vertically connected to the lower end horizontal plate 231 . The lower end horizontal plate 231 is provided with a second fixing structure 20 .

[0067] It can be understood that the position where the grains are ground is the outer surface 3 of the main body 21, and the positioning pins and screws are arranged on the upper vertical plate 222 and the lower vertical plate 232, and the upper vertical plate 222 and the lower vertical plate 232 are respectively connected to the main body 21 through the upper horizontal plate 221 and the lower horizontal plate 231, that is, the positioning pins and the screws are not on the same vertical plane as the main body 21, so the grains will not collide with the positioning pins and the screws, avoiding the impact on the grains, reducing the broken rice rate, avoiding the impact on the positioning pins and the screws, and improving the service life of the sanding sheet 2.

[0068] In some embodiments, the hard abrasive is diamond.

[0069] Specifically, the utility model provides a segmented cylinder 1 device for grain grinding, which needs to be fixedly mounted on a rotating device and driven to rotate by the rotating device. A closing device is provided on the periphery of the cylinder 1 device for tilting the grain. The grain falls downward under the action of gravity. During this process, the grain will collide with the cylinder 1 device, and the rotating cylinder 1 device will grind the grain.

[0070] It is understandable that in order to achieve grinding of grains, the outer surface 3 of the sand sheet 2 needs to be provided with hard abrasives, and the hard abrasives contact with the grains during rotation to achieve grinding of the grains.

[0071] More specifically, the hard abrasive is diamond, or other hard materials.

[0072] In a second aspect, the utility model provides a grain grinding device, comprising the sliced ​​grain grinding sand cylinder provided in the first aspect.

[0073] Specifically, the grain grinding sand cylinder is arranged inside the grain grinding equipment, and the grain grinding sand cylinder is driven to rotate by a rotating device to grind the grains.

[0074] The above description is only a preferred embodiment of the present invention and is not intended to limit the present invention. Any modifications, equivalent substitutions and improvements made within the spirit and principles of the present invention should be included in the protection scope of the present invention.
