[0033] In addition, the technical features involved in different embodiments of the present utility model described below can be combined with each other as long as they do not conflict with each other.

[0034] Such as Figure 1 and Figure 2 and Figure 3As shown in the figure, it includes a conveying component 1, a lane-dividing component 2, and a screening component 3. The inlet end of the lane-dividing component 2 is docked to the flow direction of the conveying component 1, and the screening component 3 is docked to the outlet end of the lane-dividing component 2. The conveying component 1 is used to convey high-temperature steel balls 7. The lane-dividing component 2 distributes numerous high-temperature steel balls 7 into different lane-dividing grooves 24, and then the high-temperature steel balls 7 enter the screening component 3. The steel balls 7 can move on the screening component 3, and the steel balls 7 of different sizes are separated on the screening component 3. Among them, the conveying speed of the conveying component 1 can be adjusted, and the moving speed of the steel balls 7 on the screening component 3 can also be adjusted.

[0035] The conveying component 1 includes a base 11 and a chain plate 12. The chain plate 12 is rotatably arranged on the base 11. The steel balls 7 are placed on the upper surface of the chain plate 12, and the steel balls 7 flow as the chain plate 12 rotates. The chain plate 12 can withstand high temperatures, and the rotation speed of the chain plate 12 is set according to the temperature of the steel balls 7.

[0036] The lane-dividing component 2 includes a guide plate 21. The guide plate 21 is lapped on the base 11. The inlet end of the guide plate 21 is located in the flow direction of the chain plate 12. The steel balls 7 flow from the chain plate 12 to the guide plate 21. The inlet end of the guide plate 21 is wider than the width of the chain plate 12.

[0037] The screening component 3 includes a first motor 31, a bench 32, a driving roller 33, and a flat roller 34. The driving roller 33 and the flat roller 34 are arranged in parallel at a certain distance on the bench 32. In this embodiment, the flat roller 34 does not rotate, and a set distance is maintained between the driving roller 33 and the flat roller 34. The first motor 31 is arranged on the bench 32, and the driving roller 33 is connected to the driving end of the first motor 31. The first motor 31 drives the driving roller 33 to rotate.

[0038] A gap 35 is formed between the driving roller 33 and the flat roller 34. The outlet end of the guide plate 21 is aligned with the gap 35. The steel balls 7 enter from the inlet end of the guide plate 21, and then the steel balls 7 flow out from the outlet end of the guide plate 21 and flow between the driving roller 33 and the flat roller 34. The small-sized steel balls 7 fall from the gap 35.

[0039] A set of driving roller 33 and flat roller 34 forms a gap 35. For as many lane-dividing grooves 24 as there are, the same number of sets of driving roller 33 and flat roller 34 are required to make the number of gaps 35 match the number of lane-dividing grooves 24.

[0040] A spiral wire 4 is wound around the driving roller 33. The spiral wire 4 is wound along the extending direction of the driving roller 33 to form a spiral track 36. The steel balls 7 are located on the spiral track 36. For the steel balls 7 whose size is larger than the gap 35, the steel balls 7 start to move along the spiral track 36 as the spiral wire 4 and the driving roller 33 rotate. According to the size of the steel balls 7, an appropriate spiral track 36 is formed by winding the spiral wire 4 again.

[0041] Furthermore, the spiral wire 4 and the active roller 33 are integrally formed.

[0042] The conveying assembly 1 also includes a second motor 10, a driving shaft 13 and a passive shaft 14. The second motor 10 is arranged on a base 11. The driving shaft 13 and the passive shaft 14 are rotatably arranged on the base 11. The driving shaft 13 is connected to the driving end of the second motor 10. The chain plate 12 is arranged on the driving shaft 13 and the passive shaft 14. In this example, a plurality of chain plates 12 are sleeved on the driving shaft 13 and the passive shaft 14. The plurality of chain plates 12 are connected together, and the chain plates 12 rotate on the driving shaft 13 and the passive shaft 14.

[0043] A first main sprocket 131 and a second main sprocket 132 are respectively provided at both ends of the driving shaft 13, and a first slave sprocket 141 and a second slave sprocket 142 are respectively provided at both ends of the driven shaft 14, the first main sprocket 131 and the first slave sprocket 141 are respectively provided with a first chain 15, and the second main sprocket 132 and the second slave sprocket 142 are provided with a second chain 16, and a plurality of chain plates 12 are arranged on the first chain 15 and the second chain 16 at intervals, and the first chain 15 and the second chain 16 are respectively located on both sides of the base 11, and the rotation of the driving shaft 13 drives the first main sprocket 131 and the second main sprocket 132 to rotate, the first main sprocket 131 drives the first slave sprocket 141 to rotate through the first chain 15, and the second main sprocket 132 drives the second slave sprocket 142 to rotate through the second chain 16, thereby realizing that the first chain 15 and the second chain 16 jointly drive the plurality of chain plates 12 to rotate.

[0044] The guide plate 21 is tilted, the inlet end of the guide plate 21 is higher than the outlet end, the inlet end of the guide plate 21 is wider than the outlet end, and the guide plate 21 becomes narrower as it extends. In this way, the steel balls 7 entering from the inlet end of the guide plate 21 roll toward the outlet end of the guide plate 21, and multiple steel balls 7 gather at the outlet end of the guide plate 21.

[0045] The guide plate 21 includes an integrally formed first side plate 211, a second side plate 212 and a bottom plate 213. The first side plate 211 and the second side plate 212 are respectively located on both sides of the bottom plate 213. The steel ball 7 rolls from the high end to the low end of the bottom plate 213, that is, moves from the inlet end to the outlet end of the bottom plate 213. The first side plate 211 and the second side plate 212 play a protective role, and the steel ball 7 will not slide out from both sides of the bottom plate 213.

[0046] The lane dividing assembly 2 also includes a lane dividing strip 22 and a cover plate 23. The lane dividing strip 22 is arranged on the bottom plate 213. The lane dividing strip 22 forms a lane dividing groove 24 with the first side plate 211 and the second side plate 212 respectively. In this way, only one lane dividing strip 22 is arranged, and then there are two lane dividing grooves 24. Multiple steel balls 7 are divided into the two lane dividing grooves 24. Accordingly, there are two gaps 35 for docking the two lane dividing grooves 24.

[0047] like Figure 4As shown, the cover plate 23 is arranged on the dividing strip 22, and the two ends of the cover plate 23 are respectively connected to the first side plate 211 and the second side plate 212, and the cover plate 23 covers the top of the dividing groove 24. Because the steel ball 7 rolls on the bottom plate 213 to perform an accelerated motion, and some of the steel balls 7 will hit the dividing strip 22, so that the steel ball 7 will jump up, and the steel ball 7 is prevented from jumping and sliding out of the guide plate 21. The cover plate 23 is used to cover the dividing strip 22, and the top of the dividing groove 24 is also closed at the same time, so that the steel ball 7 can only jump between the bottom plate 213 and the cover plate 23.

[0048] Furthermore, if there is more than one dividing strip 22, the dividing groove 24 is also located between adjacent dividing strips 22, and the dividing strip 22 extends and contracts as it extends from the lower end to the higher end. The dividing strip 22 is arranged in contact with the bottom plate 213, so the dividing strip 22 is also arranged at an angle, that is, the dividing strip 22 is in a contracted state from the lower end to the high end. In this example, the high end of the dividing strip 22 has a curved surface, so that the steel ball 7 will not stay at the high end position of the dividing strip 22. At the same time, the high ends of adjacent dividing strips 22 are far away from each other, so the inlet end of the dividing groove 24 has a flared opening 25, that is, the inlet end width of the dividing groove 24 is wider than the outlet end, and the outlet end of the dividing groove 24 is connected to the gap 35, and the number of gaps 35 is set according to the number of dividing strips 24.

[0049] A plurality of sets of active rollers 33 and flat rollers 34 are arranged on the stand 32 , the number of the idle spaces 35 matches the number of the channel dividing grooves 24 , and the number of the corresponding first motors 31 is arranged according to the combination of the active rollers 33 and flat rollers 34 .

[0050] The flat roller 34 includes an integrally formed uniform section 341 and a gradient section 342. The uniform section 341 is close to the guide plate 21, and the gradient section 342 is far away from the guide plate 21. The gradient section 342 becomes thinner as it extends. The gap 35 includes a uniform gap 351 and a gradient gap 352. The uniform gap 351 is located on the side of the uniform section 341, and the gradient gap 352 is located on the side of the gradient section 342. The gradient gap 352 becomes larger as it extends. The smaller steel balls 7 fall from the uniform gap 351, and the larger steel balls 7 fall from the gradient gap 352.

[0051] A recovery bin 5 is provided at the bottom of the stand 32 , and the recovery bin 5 is located at the bottom of the uniform gear 351 . The steel balls 7 falling from the uniform gear 351 enter the recovery bin 5 . An outlet 50 is also provided on the recovery bin 5 , and small-sized steel balls 7 are recovered from the outlet 50 .

[0052] A collecting plate 6 with a groove is provided at the bottom of the stand 32. The collecting plate 6 is located at the bottom of the gradient gear 352. The collecting plate 6 extends to the outer edge of the stand 32. Large-sized steel balls 7 fall from the gradient gear 352 and enter into the groove on the collecting plate 6. The collecting plate 6 is tilted, with the high end of the collecting plate 6 located at the bottom of the stand 32 and the low end of the collecting plate 6 located at the outer edge of the stand 32, so as to facilitate the collection of large-sized steel balls 7.

[0053] A support rod 8 is also provided on the outside of the collecting plate 6, and a temperature sensor 9 is provided on the support rod 8. The temperature sensor 9 is used to detect the temperature of the qualified large-size steel ball 7. If the temperature sensor 9 detects that the temperature of the steel ball 7 is too high, the chain plate 12 is adjusted to slow down the rotation. If the temperature sensor 9 detects that the temperature of the steel ball 7 is too low, the chain plate 12 is adjusted to accelerate the rotation. The speed of the chain plate 12 is adjusted according to the monitoring signal of the temperature sensor 9.

[0054] The above embodiments are only for illustrating the technical concept and features of the utility model, and their purpose is to enable people familiar with this technology to understand the content of the utility model and implement it accordingly. They cannot be used to limit the protection scope of the utility model. All equivalent changes or modifications made according to the spirit of the utility model should be included in the protection scope of the utility model.
