[0002] In the prior art, when a sample is temporarily stored, the solid particulate material that reaches the two buffer bins through the two branch pipes needs to wait for the solid particulate material inside the buffer bin to be processed and discharged before the next feeding operation is carried out.

[0013] As a preferred embodiment of the present invention, a method for using the sample temporary storage and processing device for solid particulate material inspection includes the following steps:

[0014] Step 1: After the samples are retained, they are sequentially put into the buffer bin for temporary storage. The eight buffer bins are connected to form a ring shape by connecting parts and slide on the inner side of the connecting slide rail on the workstation rack through the connecting slip ring. Under the control of the solid particle material inspection system, after the sample is placed in a buffer bin, the inspection system transmits a signal to control the output end of the stepper motor to rotate a corresponding number of circles according to the set program, so that the driving gear on the output end of the stepper motor drives the connecting slip ring to slide on the inner side of the connecting slide rail through the engaging tooth groove on the connecting slip ring, so that the adjacent buffer bins reach the loading position under rotation. The eight buffer bins are sequentially loaded during the rotation process. The solid particle material inside the buffer bin after loading can be processed;

[0015] Step 2: When the eight buffer bins are sliding on the inner side of the connecting slide rail, when the corresponding buffer bin rotates to the material receiving port position, the two different connecting blocks on the workstation frame slide into the inner side of the two trigger switches above the corresponding buffer bin respectively. When the buffer bin accurately reaches the material receiving port position, the two different connecting blocks are tightly fitted with the inner side walls of the two trigger switches respectively, so that the second energized spring inside the buffer bin contracts and drives the rotating partition to rotate to realize the separation of the upper and lower parts of the buffer bin. The first energized spring contracts and drives the adjusting cover to rotate quickly to open for the material receiving operation. The switch valve at the lower end of the buffer bin is energized and opened to allow the processed solid particulate material inside the buffer bin to fall into the vibrating feeder trough.

[0016] Step 3: When the buffer bin slides and rotates on the inner side of the connecting slide rail, the outer convex teeth on the outer side of the connecting slide rail drive the transmission gear to rotate, so that the transmission wheel connected to the lower end of the transmission gear drives the stirring shaft to rotate through the transmission belt. The spiral feeding chute connected to the lower end of the stirring shaft shovels away the solid particle material remaining on the screen filter plate during the rotation, and slides upward along the spiral feeding chute track under the action of centrifugal force and powerless pushing force. After sliding from one end of the spiral feeding chute to the inside of the miscellaneous material chute, it slides down along the inclined surface of the miscellaneous material chute and enters the crushing box from the connecting hole position. During the shaking process, the crushing box crushes the impurities on the surface of the solid particle material through the crushing knife seat at the lower end of the connecting rod. The crushed material falls from the screen hole position to the inside of the collecting structure below, and the solid particle material flows back to the inside of the screen bin from the inclined return chute position.

[0017] Compared with the prior art, the present invention has the following beneficial effects:

[0018] 1. The eight buffer bins slide on the inner side of the connecting slide rail driven by the stepper motor, so that one of the eight buffer bins is always in an idle state during the rotation process, which is convenient for the temporary storage and processing of materials. The other seven buffer bins can process solid particulate materials during the rotation process. By adjusting the rotation speed of the stepper motor, the processing operation is completed when the buffer bin rotates to the material receiving port position, without delaying the temporary storage and processing of the buffer bin;

[0019] 2. The shaking process of the crushing box drives the solid particle materials inside to collide with the fixed crushing knife seat, so that the crushing knife seat can crush the dirt on the surface of the material. The crushed dirt falls under the action of the shaking force, reducing the adverse effects of the dirt on subsequent inspection operations. BRIEF DESCRIPTION OF THE DRAWINGS

[0034] A set of connecting rails 22 are installed at the position of the cache bin 9 on the internal upper surface of the workstation rack 1. A connecting slip ring 25 is connected to the position of the connecting rail 22 on the upper surface of the cache bin 9. A number of evenly distributed interlocking tooth grooves 28 are opened on the upper surface of the connecting slip ring 25. A stepper motor is connected to the position of the connecting rail 22 on the inner side wall of the workstation rack 1. A driving gear is installed at the position of the interlocking tooth groove 28 on the output end of the stepper motor. The stepper motor drives the connecting slip ring 25 to slide on the inner side of the connecting rail 22 through the driving gear. A rotating seat is installed on one side of the surface, and an adjusting cover 23 is rotatably connected to the position of the rotating seat on the upper surface of the buffer bin 9. A connecting block is installed on one side of the upper surface of the adjusting cover 23, and a support rod 210 is installed on the upper surface of the rotating seat. The end of the support rod 210 away from the rotating seat is also connected to the connecting block. An energized spring 29 is installed between the two connecting blocks. The energized spring 29 is in an unenergized state under normal conditions, so that the adjusting cover 23 covers the feed port position above the buffer bin 9.

A plurality of evenly distributed external convex teeth 24 are integrally formed at the position of the transmission gear 27 on the outer wall of the connecting slide rail 22. A layered partition sleeve is provided above the inner wall of the cache bin 9. The layered partition sleeve is designed at an inclined angle. A rotating partition is connected to the inner part of the layered partition sleeve. An electrified spring 2 is connected to the position of the rotating partition inside the layered partition sleeve. When the electrified spring 2 is extended, the rotating partition is pushed to the inside of the layered partition sleeve. When the electrified spring 2 is contracted, the rotating partition is driven to rotate and unscrew, and together with the layered partition sleeve, the cache bin 9 is divided into two spaces, upper and lower.

[0035] In the prior art, when temporarily storing and processing samples, the solid particulate materials that reach the two buffer bins 9 through the two branch pipes need to wait for the solid particulate materials in the buffer bins 9 to complete the processing operation and discharge the solid particulate materials before the next feeding operation is carried out. This requires the temporary storage and processing of subsequent samples to wait, affecting the efficiency of the temporary storage and processing of the solid particulate materials in the buffer bins 9.

[0036] The eight buffer bins 9 are formed into a ring shape by connecting parts and slide into position on the inner side of the connecting slide rail 22 on the workstation frame 1 through the connecting slip ring 25. Under the control of the solid particle material inspection system, after the sample is placed in a buffer bin 9, the inspection system transmits a signal to control the output end of the stepper motor to rotate the corresponding number of circles according to the set program, so that the driving gear on the output end of the stepper motor drives the connecting slip ring 25 to slide on the inner side of the connecting slide rail 22 through the engaging tooth groove 28 on the connecting slip ring 25, so that the adjacent buffer bins 9 reach the loading position under rotation. The eight buffer bins 9 perform the loading operation in sequence during the rotation process. The solid particle material inside the buffer bin 9 after loading can be processed. During the processing process, the stirring frame 33 evenly stirs the solid particle material inside the buffer bin 9 to improve the processing efficiency. In the process of the eight buffer bins 9 sliding into position on the inner side of the connecting slide rail 22, when the corresponding buffer bin 9 rotates to the material receiving port position, the two different connecting blocks on the workstation frame 1 slide respectively. The hopper 26 is pressed against the top of the hopper 26 and the hopper 27 is pressed against the top of the hopper 26 to release the hopper 26. The hopper 26 is pressed against the top of the hopper 26 and the hopper 27 is pressed against the bottom of the hopper 26.

[0037] Example 2:

[0038] See also Figure 5-8As shown, a transmission wheel 32 is rotatably connected to the position of the transmission gear 27 on the inner upper surface of the buffer bin 9, and a stirring shaft 34 is rotatably connected to the middle position of the inner upper surface of the buffer bin 9. A transmission wheel 32 is also installed above the outer wall of the stirring shaft 34 at the position corresponding to the transmission wheel 32. The two transmission wheels 32 are connected through a transmission belt 31. The lower end of the stirring shaft 34 is connected to a stirring frame 33. A screening bin 38 is integrally formed at the lower end of the buffer bin 9 near the bottom of the switch valve, and a screening bin 38 is installed below the inner wall of the screening bin 38. A screening filter plate 37 is provided, and the solid particulate material entering the screening bin 38 is retained on the screening filter plate 37. The filter holes on the screening filter plate 37 can screen the solid particulate material. The solid particulate material retained on the screening filter plate 37 has impurities attached to the surface, which makes it difficult to filter out from the screening filter plate 37. The lower end of the stirring shaft 34 corresponding to the inside of the buffer bin 9 is connected to a spiral feeding trough 36. The lower surface of the spiral feeding trough 36 is also provided with a number of evenly distributed filter holes. The upper end of the spiral feeding trough 36 is away from the screening material. A blocking plate is connected to one side of the inner wall of the bin 38, and a miscellaneous material chute 39 is connected to the inner wall of the screening bin 38. The miscellaneous material chute 39 is designed at an inclined angle. A connecting hole is provided on the inner wall of the screening bin 38 corresponding to the downward tilt of the miscellaneous material chute 39. A crushing box 35 is connected to the outer wall of the screening bin 38 at the position of the connecting hole. A return trough 311 is connected to one side of the outer wall of the crushing box 35. The return trough 311 is designed to be inclined. A number of evenly distributed screening holes are provided on the lower surfaces of the crushing box 35 and the return trough 311. 312, a shaking plate 310 is slidably connected to the inner wall of the crushing box 35, and a plurality of evenly distributed telescopic sleeves 313 are connected to the lower surface of the shaking plate 310. The interior of the telescopic sleeve 313 is connected to a connecting rod 314 via a telescopic spring. The upper end of the telescopic spring is connected to an adjustable electric push rod. By adjusting the length of the electric push rod, the compression force of the telescopic spring can be adjusted. The interior of the telescopic sleeve 313 is slidably connected to a connecting rod 314, and the lower end of the connecting rod 314 is connected to a crushing knife seat 315;

[0039] In the prior art, dirt is attached to the surface of some solid particulate materials after the sample is retained. The solid particulate materials with dirt are difficult to remove during the temporary storage process. In addition, the solid particulate materials containing dirt are not conducive to the subsequent inspection system for the solid particulate materials, which makes the inspection results prone to large deviations.

[0040] During the sliding rotation of the buffer bin 9 connecting the inner side of the slide rail 22, the outer convex teeth 24 connecting the outer side of the slide rail 22 drive the transmission gear 27 to rotate, so that the transmission wheel 32 connected to the lower end of the transmission gear 27 drives the stirring shaft 34 to rotate through the transmission belt 31. The spiral feeding chute 36 connected to the lower end of the stirring shaft 34 shovels away the solid particulate material remaining on the screening filter plate 37 during the rotation process, and slides upward along the track of the spiral feeding chute 36 under the action of centrifugal force and powerless pushing force. After sliding from one end of the spiral feeding chute 36 to the inside of the miscellaneous material chute 39, it slides down along the inclined surface of the miscellaneous material chute 39 and enters the inside of the crushing box 35 from the position of the connecting hole. The shaking plate 310 is connected to The workstation frame 1 is not affected by the shaking of the buffer bin 9, and the crushing box 35 shakes under the drive of the buffer bin 9. During the shaking process, the impurities on the surface of the solid particle material are crushed by the crushing knife seat 315 at the lower end of the connecting rod 314. During the crushing process, the squeezing force of the crushing knife on the crushing knife seat 315 on the dirt on the surface of the material can be adjusted by adjusting the length of the electric push rod connected to the telescopic spring, so that the crushing knife seat 315 can crush the dirt on the surface of the material without causing damage to the material. The crushed material falls from the position of the screening hole 312 to the inside of the collecting structure below, and the solid particle material flows back to the inside of the screening bin 38 from the inclined return trough 311.

[0041] When the present invention is in use, the eight buffer bins 9 are formed into a ring shape by the connecting parts and slide on the inner side of the connecting slide rail 22 on the workstation frame 1 through the connecting slip ring 25. Under the control of the solid particle material inspection system, after the sample is placed in the interior of a buffer bin 9, the inspection system transmits a signal to control the output end of the stepper motor to rotate a corresponding number of circles according to the set program, so that the driving gear on the output end of the stepper motor drives the connecting slip ring 25 to slide on the inner side of the connecting slide rail 22 through the engaging tooth groove 28 on the connecting slip ring 25, so that the adjacent buffer bins 9 reach the loading position under rotation, and the eight buffer bins 9 perform the loading operation in turn during the rotation process. The internal solid particle material can be processed in the buffer bin 9 after loading. During the processing, the stirring frame 33 stirs the buffer bin 9 The solid particulate material inside is evenly stirred to improve the processing efficiency. In the process of the eight buffer bins 9 sliding on the inner side of the connecting slide rail 22, when the corresponding buffer bin 9 rotates to the material receiving port position, the two different connecting blocks on the workstation frame 1 slide into the inner side of the two trigger switches 26 above the corresponding buffer bin 9 respectively. When the buffer bin 9 accurately reaches the material receiving port position, the two different connecting blocks are tightly fitted with the inner side walls of the two trigger switches 26, so that the energized spring 2 inside the buffer bin 9 contracts and drives the rotating partition to rotate to realize the separation of the upper and lower parts of the buffer bin 9. The energized spring 1 29 is energized and contracts to drive the adjusting cover 23 to rotate and open quickly to perform the material receiving operation. The switch valve at the lower end of the buffer bin 9 is energized and opened to make the solid particulate material processed inside the buffer bin 9 fall into the vibrating feeding trough 8.

[0042] During the sliding rotation of the buffer bin 9 connecting the inner side of the slide rail 22, the outer convex teeth 24 connecting the outer side of the slide rail 22 drive the transmission gear 27 to rotate, so that the transmission wheel 32 connected to the lower end of the transmission gear 27 drives the stirring shaft 34 to rotate through the transmission belt 31, and the spiral feeding chute 36 connected to the lower end of the stirring shaft 34 shovels away the solid particulate material remaining on the screening filter plate 37 during the rotation, and slides upward along the track of the spiral feeding chute 36 under the action of centrifugal force and powerless pushing force, and slides from one end of the spiral feeding chute 36 to the inside of the miscellaneous material chute 39, and then slides down along the inclined surface of the miscellaneous material chute 39 and enters the inside of the crushing box 35 from the position of the connecting hole. The shaking plate 310 is connected to the workstation frame 1 and is not affected by the shaking of the buffer bin 9. The crushing box 35 is shaken by the drive of the buffer bin 9. During the shaking process, the connecting rod 3 The crushing knife seat 315 at the lower end of 14 crushes impurities on the surface of the solid particle material. During the crushing process, the squeezing force of the crushing knife on the crushing knife seat 315 on the dirt on the material surface can be adjusted by adjusting the length of the electric push rod connected to the telescopic spring, so that the crushing knife seat 315 can crush the dirt on the material surface without damaging the material. The crushed material falls from the screening hole 312 to the inner side of the collecting structure below, and the solid particle material returns to the inside of the screening bin 38 from the inclined return trough 311. During the shaking process of the crushing box 35, the solid particle material inside is driven to collide with the fixed crushing knife seat 315, so that the crushing knife seat 315 can crush the dirt on the material surface. The crushed dirt falls under the action of the shaking force, reducing the adverse effect of the dirt on subsequent inspection operations.

2. A method for using the solid particulate material testing sample temporary storage and processing device according to claim 1, characterized in that: The method for using the sample temporary storage and processing device for solid particulate material inspection includes the following steps: Step 1: After the sample is retained, the sample enters the buffer bin (9) in turn for temporary storage operation. The eight buffer bins (9) are surrounded by a connecting piece to form a ring shape, and slide on the inner side of the connecting slide rail (22) on the workstation frame (1) through the connecting slip ring (25). Under the control of the solid particle material inspection system, after the sample is placed inside a buffer bin (9), the inspection system transmits a signal to control the output end of the stepper motor to rotate a corresponding number of circles according to the set program, so that the driving gear on the output end of the stepper motor drives the connecting slip ring (25) to slide on the inner side of the connecting slide rail (22) through the engaging tooth groove (28) on the connecting slip ring (25), so that the adjacent buffer bins (9) reach the loading position under rotation. The eight buffer bins (9) perform the loading operation in turn during the rotation process. The solid particle material inside the buffer bin (9) after loading can be processed; Step 2: When the eight buffer bins (9) slide on the inner side of the connecting slide rail (22), when the corresponding buffer bin (9) rotates to the material receiving port position, the two different connecting blocks on the workstation frame (1) slide into the inner side of the two trigger switches (26) above the corresponding buffer bin (9), and when the buffer bin (9) accurately reaches the material receiving port position, the two different connecting blocks are tightly fitted with the inner side walls of the two trigger switches (26), so that the second energized spring inside the buffer bin (9) contracts and drives the rotating partition to rotate to realize the separation of the upper and lower parts of the buffer bin (9), and the first energized spring contracts and drives the regulating cover (23) to rotate and open quickly to perform the material receiving operation, and the switch valve at the lower end of the buffer bin (9) is energized and opened to make the solid particulate material processed inside the buffer bin (9) fall into the vibrating feed trough (8); Step 3: When the buffer bin (9) slides and rotates on the inner side of the connecting slide rail (22), the outer convex teeth (24) on the outer side of the connecting slide rail (22) drive the transmission gear (27) to rotate, so that the transmission wheel (32) connected to the lower end of the transmission gear (27) drives the stirring shaft (34) to rotate through the transmission belt (31). The spiral feeding trough (36) connected to the lower end of the stirring shaft (34) shovels away the solid particle materials remaining on the screening filter plate (37) during the rotation process, and moves along the trajectory of the spiral feeding trough (36) under the action of centrifugal force and powerless pushing force. The material slides upwards and slides down from one end of the spiral feeding chute (36) to the inside of the miscellaneous material chute (39), then slides down along the inclined surface of the miscellaneous material chute (39) and enters the inside of the crushing box (35) from the position of the connecting hole. During the shaking process, the crushing box (35) crushes the impurities on the surface of the solid particle material through the crushing knife seat (315) at the lower end of the connecting rod (314). The crushed material falls from the position of the screening hole (312) to the inside of the collecting structure below, and the solid particle material flows back to the inside of the screening bin (38) from the position of the inclined return chute (311).
