Diamond selection device and auxiliary mechanism thereof

Abstract

The application provides a diamond selecting device and an auxiliary mechanism thereof, and relates to the technical field of diamond selecting. The diamond selecting device comprises a bottom plate and a vibrating disc. The vibrating disc can generate vibration and is arranged at an angle with the horizontal plane. The vibrating disc is circular and rotationally arranged on the bottom plate. The vibrating disc is used for feeding materials to a first position in a working area. The first position is close to the center of the vibrating disc. The materials roll along the vibrating disc to a lower position under the action of gravity and vibration. Since the terminal point of the rolling is the edge of the circular vibrating disc, and the distance from each part of the edge of the circular vibrating disc to the feeding point is basically the same, which is the radius of the vibrating disc, the distance and time of the movement of the materials on the vibrating disc are basically consistent. Therefore, the probability of the mixing of materials in different particle size intervals is reduced, and the selecting precision is improved. The circular vibrating disc can continuously rotate at a low speed, so that the wear degree of different positions on the surface of the vibrating disc is basically consistent. The hindering effect on the movement of the materials is reduced, and the selecting efficiency is improved.

Description

Technical Field

[0001] This invention relates to the field of diamond selection technology, and in particular to a diamond selection device and its auxiliary mechanism. Background Technology

[0002] In the field of superhard materials, there are numerous synthetic products, including artificial diamond, cubic boron nitride (CBN), and composite sheets. These are mass-produced through press synthesis and are widely used in many industrial sectors such as machining, oil and gas drilling, and precision instruments. Diamond sorting, a key process in diamond processing, involves classifying particles based on their geometry (e.g., cubic, octahedral, and interlocking crystals). Currently, specialized sorting machines are generally used to select diamonds, precisely controlling vibration parameters (e.g., frequency, amplitude) and the tilt angle of the platform. When diamond particles are vibrated and roll down a specific tilted platform, the different shapes of particles, due to differences in their contact geometry with the platform, moment of inertia, and friction, result in different rolling trajectories. Ultimately, particles of different shapes fall into different collection areas, thus achieving automatic shape screening and separation.

[0003] Existing diamond sorting machines typically use a triangular vibratory plate with an inclined orientation. Material is fed from the highest point of the vibratory plate, and under the action of gravity and vibration, the material rolls down the vibratory plate. Since the end of the rolling is the base of the triangle, and the distance between the base and the feeding point varies, the distance and time the material travels on the vibratory plate differ, causing mixing of materials from different particle size ranges and affecting sorting accuracy. In addition, after long-term use, the triangular vibratory plate will experience uneven wear on different parts of its surface, which will hinder material movement to some extent and reduce sorting efficiency.

[0004] The information disclosed in the background section of this invention is intended only to enhance the understanding of the general background of this invention, and should not be construed as an admission or in any way implying that such information constitutes prior art known to those skilled in the art. Summary of the Invention

[0005] Therefore, it is necessary to provide a diamond selection device and its auxiliary mechanism to address the problems existing in current diamond selection machines.

[0006] The above objectives are achieved through the following technical solutions:

[0007] A diamond selection device includes a base plate and a vibratory feeder. The vibratory feeder is capable of vibration and is set at an angle to a horizontal plane. The vibratory feeder is circular and rotatably mounted on the base plate. The base plate is also provided with a baffle assembly, a collection bin, and a feeding assembly. The baffle assembly is used to form a fan-shaped working area on the vibratory feeder. The surface of the vibratory feeder includes a first area and a second area, both of which are semi-circular. The first area is higher than the second area, and the working area overlaps with the second area. Multiple collection bins are arranged sequentially along the circumference of the vibratory feeder. The collection bins are located below the edge of the vibratory feeder and correspond to the working area. The feeding assembly is used to feed material to a first position on the vibratory feeder. The first position is located within the working area and forms a preset distance from the center of the vibratory feeder. The material moves from the first position to the edge of the vibratory feeder and enters the corresponding collection bin.

[0008] Furthermore, the base plate is provided with a fixed shaft, the vibratory feeder is rotatably connected to the fixed shaft, and the enclosure assembly includes two enclosure rollers arranged at an included angle. The enclosure rollers are arranged radially along the vibratory feeder, one end of the enclosure roller is rotatably mounted on the fixed shaft, and the other end of the enclosure roller extends to the edge of the vibratory feeder. The outer surface of the enclosure roller is in rolling contact with the surface of the vibratory feeder.

[0009] Furthermore, the diameter of the containment roller gradually increases from near to far from the fixed axis.

[0010] Furthermore, the two enclosure rollers form a first included angle, and a first adjusting member is provided on the fixed shaft, the first adjusting member being used to change the first included angle.

[0011] Furthermore, it also includes a support frame, the vibrating plate forming a second angle with the horizontal plane, the support frame having a horizontal rotating shaft, one end of the base plate being rotatably connected to the horizontal rotating shaft, and the other end of the base plate being able to move away from or closer to the support frame to change the second angle.

[0012] Furthermore, the first adjusting member is also used to make the two containment rollers rotate synchronously about the fixed axis.

[0013] Furthermore, a guide ring coaxial with the vibrating plate is rotatably provided on the base plate, and a plurality of collection bins are sequentially arranged on the guide ring along the circumference of the vibrating plate. The guide ring is provided with through holes corresponding to the collection bins, and the material enters the corresponding collection bins sequentially from the edge of the vibrating plate and the through holes.

[0014] Furthermore, the inner side of the guide ring is lower than the surface of the vibratory feeder, and the outer side of the guide ring is higher than the surface of the vibratory feeder.

[0015] Furthermore, the base plate is provided with a first support plate and a second support plate, the first support plate is located between the base plate and the second support plate, a plurality of first elastic elements are provided between the base plate and the first support plate, a vibrator and a plurality of second elastic elements are provided between the first support plate and the second support plate, and the vibrating plate is rotatably connected to the second support plate.

[0016] This invention also provides the following technical solutions:

[0017] An auxiliary mechanism for a diamond selection device includes a cleaning roller mounted on a fixed shaft. The cleaning roller is arranged radially along the vibratory disk and located outside the working area. One end of the cleaning roller is rotatably mounted on the fixed shaft, and the other end of the cleaning roller extends to the edge of the vibratory disk. The outer surface of the cleaning roller makes rolling contact with the surface of the vibratory disk.

[0018] The beneficial effects of this invention are:

[0019] Material is fed to the first position within the working area, which is close to the center of the vibratory feeder. Under the influence of gravity and vibration, the material rolls downwards along the vibratory feeder. Since the rolling endpoint is at the edge of the circular vibratory feeder, and the distance between the edge of the circular vibratory feeder and the feeding point is basically the same (equivalent to the radius of the vibratory feeder), the distance and time the material travels on the vibratory feeder are basically consistent. This reduces the probability of mixing materials from different particle size ranges and improves selection accuracy. In addition, the circular vibratory feeder can rotate continuously at a low speed, ensuring that the wear on different parts of its surface is basically uniform, reducing the obstruction to material movement and improving selection efficiency.

[0020] The cleaning roller is used to help remove the fine powder adhering to the surface of the vibratory plate, thus avoiding abrasive wear and further adhesion of fine powder to the surface of the vibratory plate. Attached Figure Description

[0032] To make the objectives, technical solutions, and advantages of this invention clearer, the invention will be further described in detail below through embodiments and in conjunction with the accompanying drawings. It should be understood that the specific embodiments described herein are merely illustrative of the invention and are not intended to limit the invention.

[0033] The component designations used in this document, such as "first" and "second," are merely for distinguishing the described objects and do not have any sequential or technical meaning. The terms "connection" and "linkage" used in this invention, unless otherwise specified, include both direct and indirect connections (linkages). It should be understood that the terms "upper," "lower," "front," "rear," "left," "right," "vertical," "horizontal," "top," "bottom," "inner," "outer," "clockwise," and "counterclockwise," indicating orientations or positional relationships, are based on the orientations or positional relationships shown in the accompanying drawings and are used only for the convenience of describing the invention and simplifying the description. They do not indicate or imply that the device or element referred to must have a specific orientation, or be constructed and operated in a specific orientation, and therefore should not be construed as limiting the invention.

[0034] In this invention, unless otherwise explicitly specified and limited, "above" or "below" the second feature can mean that the first feature is in direct contact with the second feature, or that the first feature is in indirect contact with the second feature through an intermediate medium. Furthermore, "above," "over," and "on top" of the second feature can mean that the first feature is directly above or diagonally above the second feature, or simply that the first feature is at a higher horizontal level than the second feature. "Below," "below," and "under" the second feature can mean that the first feature is directly below or diagonally below the second feature, or simply that the first feature is at a lower horizontal level than the second feature.

[0035] like Figures 1 to 8 As shown, this embodiment of the invention provides a diamond selection device, including a base plate 100 and a vibratory feeder 101. The vibratory feeder 101 is capable of generating vibration and is set at an angle to the horizontal plane. The vibratory feeder 101 is circular and rotatably mounted on the base plate 100. The base plate 100 is also provided with a baffle assembly, a collection bin 102, and a feeding assembly. The baffle assembly is used to form a fan-shaped working area 201 on the vibratory feeder 101. The surface of the vibratory feeder 101 includes a first area and a second area, both of which are semi-circular. The first area is located on the upper side of a first plane, and the second area is located on the first plane. On the lower side, the first plane is a horizontal plane passing through the center of the vibrating plate 101, and the working area 201 and the second area have an overlapping part; multiple collection bins 102 are arranged sequentially along the circumference of the vibrating plate 101. The collection bins 102 are located below the edge of the vibrating plate 101 and are arranged corresponding to the working area 201. The feeding component is used to feed material to the first position on the vibrating plate 101. The first position is located in the working area 201 and forms a preset distance from the center of the vibrating plate 101. The material moves from the first position to the edge of the vibrating plate 101 and enters the corresponding collection bin 102.

[0036] Material is fed into the first position within the working area 201, and this first position is close to the center of the vibratory disk 101. Under the action of gravity and vibration, the material rolls downward along the vibratory disk 101. Since the end point of the rolling is the edge of the circular vibratory disk 101, and the distance between the edge of the circular vibratory disk 101 and the feeding point is basically the same (i.e., the radius of the vibratory disk 101), the distance and time the material moves on the vibratory disk 101 are basically consistent. This reduces the probability of mixing of materials from different particle size ranges and improves the selection accuracy. In addition, the circular vibratory disk 101 can rotate continuously at a low speed, making the wear degree of different positions on its surface basically consistent, reducing the obstruction to the movement of materials and improving the selection efficiency.

[0037] The first plane can also be understood as the horizontal diameter of the vibratory feeder 101. Since the vibratory feeder 101 is circular and inclined, it can be divided into two regions by the first plane: a higher first region and a lower second region. The height of all points in the first region is higher than the height of all points in the second region. Furthermore, the working area 201 overlaps with the second region, and after the material is fed by the feeding component, it mainly moves within this overlapping portion and eventually reaches the collection bin 102.

[0038] The feeding assembly includes an inclined guide trough 103 and a feeding pipe 104. The upper end of the feeding pipe 104 is connected to the bottom of the guide trough 103, and the lower end of the feeding pipe 104 is located above the vibrating plate 101 and facing the first position. The diamond material is conveyed into the guide trough 103 and falls into the first position along the feeding pipe 104.

[0039] In one embodiment, a fixed shaft 202 is provided on the base plate 100, and the vibratory plate 101 is rotatably connected to the fixed shaft 202. The enclosure assembly includes two enclosure rollers 203 arranged at an included angle. The enclosure rollers 203 are arranged radially along the vibratory plate 101. One end of the enclosure roller 203 is rotatably mounted on the fixed shaft 202, and the other end of the enclosure roller 203 extends to the edge of the vibratory plate 101. The outer surface of the enclosure roller 203 is in rolling contact with the surface of the vibratory plate 101.

[0040] Two baffle rollers 203 form a working area 201 on the surface of the vibratory plate 101. When the vibratory plate 101 rotates around the fixed shaft 202, it drives the two baffle rollers 203 to rotate in the same direction. One of the baffle rollers 203 can push the material in contact with it toward the working area 201, so that all the material moves only along the working area 201 toward the edge of the vibratory plate 101.

[0041] The preset distance can be greater than 0, meaning the first position is close to the center of the vibratory plate 101, so that the distance between the edge of the circular vibratory plate 101 and the feeding point is basically the same, which is the radius of the vibratory plate 101. However, in reality, the distance between the edge of the circular vibratory plate 101 and the feeding point is slightly smaller than the radius of the vibratory plate 101, but still basically the same. Of course, as an optional structural variation, the preset distance can also be 0, meaning the first position is the center of the vibratory plate 101. In this case, the ends of the two retaining rollers 203 that are close to each other are not beyond the rotation axis of the vibratory plate 101, and the center of the vibratory plate 101 is located between the two retaining rollers 203. An additional fixing mechanism can be provided to install the two retaining rollers 203 on the base plate 100.

[0042] Among them, such as Figure 4As shown, the working area 201 is located between the two retaining rollers 203. At this time, the working area 201 is entirely within the second area. The end of the left retaining roller 203 is closer to the lowest point of the edge of the vibrating plate 101, while the end of the right retaining roller 203 is farther from the lowest point of the edge of the vibrating plate 101. Therefore, after falling, the material tends to move closer to the left retaining roller 203 and further away from the right retaining roller 203. When the vibrating plate 101 rotates counterclockwise, both retaining rollers 203 also rotate counterclockwise. When the left retaining roller 203 rotates, it can push the material in contact with it towards the right working area 201, thus ensuring that all material moves only along the working area 201 towards the edge of the vibrating plate 101.

[0043] In one embodiment, the diameter of the containment roller 203 gradually increases from near to far from the fixed shaft 202.

[0044] As the material moves from the first position to the edge of the vibratory plate 101 along the working area 201, the amplitude of the material's movement relative to the vibratory plate 101 gradually increases. By gradually increasing the diameter of the retaining roller 203, the retaining effect on the material is gradually enhanced, preventing the material from spilling off the vibratory plate 101 and causing waste.

[0045] In one embodiment, two containment rollers 203 form a first included angle, and a first adjusting member is provided on the fixed shaft 202 to change the first included angle.

[0046] The selection accuracy is adjusted by changing the first included angle. Specifically, the larger the first included angle, the larger the working area 201 formed on the vibratory feeder 101, and the more collection chambers 102 are set accordingly, thus the higher the selection accuracy; the smaller the first included angle, the smaller the working area 201 formed on the vibratory feeder 101, and the fewer collection chambers 102 are set accordingly, thus the lower the selection accuracy.

[0047] The number of collection chambers 102 can be set selectively. Preferably, the central angle of the arc corresponding to all collection chambers 102 is equal to 180°.

[0048] Among them, see Figure 3 The first adjusting component includes an arc-shaped plate 204 and a first nut 205. A screw 206 is formed at the upper end of the fixed shaft 202. The first nut 205 is threadedly connected to the screw 206. The arc-shaped plate 204 is disposed between the lower end face of the first nut 205 and the upper end face of the fixed shaft 202. Rotating the first nut 205 moves it closer to the upper end face of the fixed shaft 202 to fix the arc-shaped plate 204. Conversely, rotating the first nut 205 in the opposite direction moves it away from the upper end face of the fixed shaft 202 to loosen the arc-shaped plate 204. At this time, the arc-shaped plate 204 corresponding to one of the retaining rollers 203 can be moved to adjust the first included angle formed by the two retaining rollers 203.

[0049] In one embodiment, see Figure 2 , Figure 7 It also includes a support 105, a vibrating plate 101 forming a second angle with the horizontal plane, a horizontal rotating shaft 207 on the support 105, one end of the base plate 100 being rotatably connected to the horizontal rotating shaft 207, and the other end of the base plate 100 being able to move away from or closer to the support 105 to change the second angle.

[0050] The target selection particle size is adjusted by changing the second included angle. Specifically, the larger the second included angle, the faster the material moves along the vibrating plate 101, the larger the target selection particle size, and the greater the amount of material that can be selected per unit time, suitable for coarse selection or easy-to-select materials; the smaller the second included angle, the slower the material moves along the vibrating plate 101, the smaller the target selection particle size, and the smaller the amount of material that can be selected per unit time, suitable for fine selection or difficult-to-select materials. For example, the correspondence between diamond grade, target particle size, and second included angle is shown in the table below:

[0051]

[0052] The horizontal rotating shaft 207 is equipped with a mounting rod 208 and a telescopic component 209. The telescopic component 209 can be a hydraulic cylinder or an electric push rod, and is equipped with a corresponding drive source and controller to control its start and stop. One end of the mounting rod 208 is connected to the horizontal rotating shaft 207, and the other end is fixed to the fixed end of the telescopic component 209. The output end of the telescopic component 209 is rotatably connected to the other end of the base plate 100. When the output end of the telescopic component 209 extends or retracts relative to its fixed end, it pushes or pulls on the other end of the base plate 100, causing the other end of the base plate 100 to move away from or closer to the bracket 105, thereby changing the second included angle. In addition, the bracket 105 can be a frame structure similar to table legs. When the base plate 100 moves to a horizontal position, the bracket 105 can also support the four corners of the base plate 100.

[0053] In one embodiment, the first adjusting member is also used to cause the two containment rollers 203 to rotate synchronously about the fixed shaft 202.

[0054] When the two retaining rollers 203 rotate synchronously around the fixed shaft 202, the position of the working area 201 changes, thereby altering the material's movement speed along the vibrating disk 101 and adjusting the target particle size. Specifically, the further the working area 201 is from the first plane, the greater the material's movement speed along the vibrating disk 101, and the larger the target particle size, thus increasing the amount of material that can be selected per unit time; conversely, the closer the working area 201 is to the first plane, the smaller the material's movement speed along the vibrating disk 101, and the smaller the target particle size, thus reducing the amount of material that can be selected per unit time.

[0055] Specifically, the first nut 205 is rotated in the opposite direction to move it away from the upper end face of the fixed shaft 202, so as to loosen the arc plate 204. At this time, the arc plates 204 corresponding to the two enclosure rollers 203 can be moved synchronously so that the two enclosure rollers 203 can rotate synchronously around the fixed shaft 202.

[0056] In one embodiment, a guide ring 210 coaxial with the vibratory feeder 101 is rotatably provided on the base plate 100. Multiple collection bins 102 are sequentially arranged on the guide ring 210 along the circumference of the vibratory feeder 101. The guide ring 210 is provided with through holes 211 corresponding to the collection bins 102. The material enters the corresponding collection bins 102 sequentially from the edge of the vibratory feeder 101 and the through holes 211.

[0057] Rotate the guide ring 210 to drive the collection bin 102 to rotate circumferentially along the vibrating plate 101, so as to adjust the position of the collection bin 102 relative to the two retaining rollers 203.

[0058] Among them, see Figure 4 A gear ring 212 is coaxially mounted on the base plate 100 and rotates with the vibrating plate 101. A guide ring 210 is fixed on the gear ring 212. A spur gear 213 and a handle 214 are also rotatably mounted on the base plate 100. The spur gear 213 meshes with the gear ring 212. Rotating the handle 214 drives the spur gear 213 to rotate, which in turn drives the gear ring 212, the guide ring 210, and the collection bin 102 to rotate together along the circumference of the vibrating plate 101, thereby manually adjusting the position of the collection bin 102 relative to the two retaining rollers 203.

[0059] In one embodiment, the inner side of the guide ring 210 is lower than the surface of the vibratory plate 101, and the outer side of the guide ring 210 is higher than the surface of the vibratory plate 101.

[0060] The inner side of the guide ring 210 is lower to avoid the movement trajectory of the material, allowing the material to smoothly enter the through hole 211 from the edge of the vibrating plate 101. The outer side of the guide ring 210 is higher to block the material, thereby reducing the probability of the material rushing out of the guide ring 210 and spilling.

[0061] The guide ring 210 has an inner wall and an outer wall due to the through hole 211. The inner wall is lower to facilitate the passage of material into the through hole 211, while the outer wall is higher to block the material. In addition, the central angle of the guide ring 210 can be 180° to accommodate a corresponding number of collection bins 102.

[0062] In one embodiment, see Figure 2 , Figure 6 , Figure 8The base plate 100 is provided with a first support plate 215 and a second support plate 216. The first support plate 215 is located between the base plate 100 and the second support plate 216. A plurality of first elastic elements 217 are provided between the base plate 100 and the first support plate 215. A vibrator 218 and a plurality of second elastic elements 219 are provided between the first support plate 215 and the second support plate 216. The vibrating plate 101 is rotatably connected to the second support plate 216.

[0063] The vibrator 218 transmits vibration to the second support plate 216 and the vibrating plate 101. At the same time, the first elastic element 217 and the second elastic element 219 support the first support plate 215, the second support plate 216 and the vibrating plate 101 to limit the vibration amplitude of the vibrating plate 101 within a certain range.

[0064] The vibrator 218 can be of electromagnetic or piezoelectric ceramic type, and is equipped with a corresponding power controller to control its start / stop and related vibration parameters. The structure and working principle of the vibrator 218 are existing technologies and will not be described in detail here. Additionally, the first elastic element 217 is a spring, and the second elastic element 219 is an elastic plate.

[0065] Among them, see Figure 6 , Figure 8 A fixed shaft 202 is fixed to the first support plate 215. A support cylinder 220 is coaxially fixed to the lower side of the vibratory feeder 101. A second support plate 216 is rotatably mounted outside the support cylinder 220. The fixed shaft 202 passes through the support cylinder 220 and the vibratory feeder 101 in sequence and is rotatably mounted with a retaining roller 203. A motor 221 is mounted on the second support plate 216, and a corresponding power controller is configured to control its start and stop. The output end of the motor 221 is equipped with a first bevel gear 222. The support cylinder 220 is equipped with a second bevel gear 223 that meshes with the first bevel gear 222. The pitch circle diameter and number of teeth of the first bevel gear 222 are both smaller than those of the second bevel gear 223 for speed reduction transmission. The output end of the motor 221 drives the first bevel gear 222 to rotate, which in turn drives the second bevel gear 223, the support cylinder 220, and the vibratory feeder 101 to rotate synchronously.

[0066] This invention also provides an auxiliary mechanism for a diamond selection device. A cleaning roller 224 is provided on a fixed shaft 202. The cleaning roller 224 is arranged radially along the vibratory disk 101 and located outside the working area 201. One end of the cleaning roller 224 is rotatably mounted on the fixed shaft 202, and the other end of the cleaning roller 224 extends to the edge of the vibratory disk 101. The outer surface of the cleaning roller 224 makes rolling contact with the surface of the vibratory disk 101.

[0067] The vibratory plate 101 rotates around the fixed shaft 202, driving the cleaning roller 224 to rotate. The cleaning roller 224 rolls and contacts the vibratory plate 101 to clean and remove the micro powder adhering to the surface of the vibratory plate 101, avoiding the formation of abrasive wear and aggravating the adhesion of micro powder to the surface of the vibratory plate 101, thereby achieving auxiliary cleaning in the diamond selection process.

[0068] The position of the cleaning roller 224 is also adjustable. See [link / reference] Figure 3 The screw 206 is also threaded with a second nut 225. A sleeve 226 is provided between the second nut 225 and the first nut 205. One end of the cleaning roller 224 is rotatably mounted on the sleeve 226. By controlling the distance between the second nut 225 and the first nut 205, the sleeve 226 can be locked or unlocked, thereby adjusting the setting position of the cleaning roller 224.

[0069] In use, the vibrator 218 causes the vibrating disk 101 to vibrate, feeding material into a first position within the working area 201. This first position is close to the center of the vibrating disk 101. Under the influence of gravity and vibration, the material rolls downwards along the vibrating disk 101. Since the rolling endpoint is the edge of the circular vibrating disk 101, and the distance between the edge of the circular vibrating disk 101 and the feeding point is basically the same (equivalent to the radius of the vibrating disk 101), the distance and time the material travels on the vibrating disk 101 are essentially consistent. This reduces the probability of mixing materials of different particle sizes and improves selection accuracy. In addition, the output of the motor 221 drives the first bevel gear 222 to rotate, which in turn drives the second bevel gear 223, the support cylinder 220, and the vibrating disk 101 to rotate synchronously. This means that the circular vibrating disk 101 can rotate continuously at a low speed, ensuring that the wear on different parts of its surface is basically uniform, reducing the obstruction to material movement and improving selection efficiency.

[0070] Two baffle rollers 203 form a working area 201 on the surface of the vibratory plate 101. When the vibratory plate 101 rotates around the fixed shaft 202, it drives the two baffle rollers 203 to rotate in the same direction. One of the baffle rollers 203 can push the material in contact with it toward the working area 201, so that all the material moves only along the working area 201 toward the edge of the vibratory plate 101.

[0071] During the selection process, the selection accuracy can be adjusted by changing the first included angle formed by the two containment rollers 203; the target selection particle size can also be adjusted by changing the second included angle formed by the vibratory plate 101 and the horizontal plane; the position of the working area 201 can also be changed by making the two containment rollers 203 rotate synchronously around the fixed shaft 202, and the position of the collection bin 102 relative to the two containment rollers 203 can be adjusted accordingly, thereby further adjusting the target selection particle size; in addition, the cleaning roller 224 is used to assist in cleaning and removing the micro powder attached to the surface of the vibratory plate 101, so as to avoid abrasive wear and aggravation of micro powder adhesion on the surface of the vibratory plate 101.

[0072] The technical features of the above embodiments can be combined in any way. For the sake of brevity, not all possible combinations of the technical features in the above embodiments are described. However, as long as there is no contradiction in the combination of these technical features, they should be considered to be within the scope of this specification.

[0073] The embodiments described above are merely illustrative of several implementations of the present invention, and while the descriptions are specific and detailed, they should not be construed as limiting the scope of the invention. It should be noted that those skilled in the art can make various modifications and improvements without departing from the concept of the present invention, and these modifications and improvements all fall within the scope of protection of the present invention. Therefore, the scope of protection of the present invention should be determined by the appended claims.
