Based on the embodiments of the present utility model, all other embodiments obtained by those of ordinary skill in the art without creative effort are within the protection scope of the present utility model.
[0029] Reference Figure 1 , Figure 2The present invention provides an embodiment of a separation device for testing the fullness of rice grains, comprising a separation box 1, a diversion box 7, a feeding box 5, two fixing mechanisms 4, and multiple guide plates 18. A threaded column 6 is rotatably connected to the front wall of the inner wall of the feeding box 5. A drive motor 8 is fixedly connected to the rear of the feeding box 5. The output end of the drive motor 8 passes through the rear of the feeding box 5 and extends into the interior. The output end of the drive motor 8 is fixedly connected to one end face of the threaded column 6. The lower end face of the feeding box 5 is fixedly connected to the upper end face of the diversion box 7.
[0030] Specifically, a large amount of rice is put into the feeding box 5, and the output end of the drive motor 8 outputs power, causing the threaded column 6 to rotate. The rice is then transported in an orderly manner from both sides to the diversion box 7 through the threads on the threaded column 6.
[0031] Reference Figure 1 , Figure 2 , Figure 3 The lower end face of the diversion box 7 is fixedly connected to the upper end face of the inlet hole 10. Insertion holes 21 are provided at the top, bottom, and center of the bottom slope of the diversion box 7. Limiting blocks 19 are fixedly connected to both sides of the diversion box 7. The outer surfaces of the two limiting blocks 19 are respectively movably fitted inside the two connecting holes 401. Support legs 2 are fixedly connected to both sides of the lower end face of the diversion box 7. A blower 9 is fixedly fitted inside the diversion box 7 at the rear. Multiple No. 3 diversion plates 17 are fixedly connected to the upper part of the inner bottom slope of the diversion box 7. Multiple No. 2 diversion plates 16 are fixedly connected to the center of the inner bottom slope of the diversion box 7. Multiple No. 1 diversion plates 15 are fixedly connected to the lower part of the inner bottom slope of the diversion box 7. Locking blocks 20 are fixedly connected to both sides of the multiple guide plates 18. The outer surfaces of the multiple guide plates 18 are respectively movably fitted inside the multiple insertion holes 21.
[0032] Specifically, the guide plate 18 is inserted into the diverter box 7 through the insertion hole 21. The inclined surface of the locking block 20 on the guide plate 18 fits perfectly with the inclined surface at the bottom of the diverter box 7. The connecting rod 403 is moved by the fixing block 402, and the connecting block 404 on the connecting rod 403 is inserted into the hole on the locking block 20. Then, the fixing block 402 is hung on the limiting block 19 through the connecting hole 401 on the fixing block 402, thereby fixing the guide plate 18. Conversely, it can be removed for cleaning. Multiple No. 1 diverter plates 15, multiple No. 2 diverter plates 16, and multiple No. 3 diverter plates are also present. Plates 17 are fixedly connected to multiple insertion holes 21 on the inclined surface of the bottom of the diversion box 7. Multiple No. 3 diversion plates 117 are placed facing one side, multiple No. 2 diversion plates 16 are placed facing the other side, and multiple No. 1 diversion plates 15 are placed symmetrically, so that the rice grains slide in different directions on the guide plate 18. The guide plate 18 has multiple rectangular holes for separating full rice grains from unfull rice grains. The separation rate of full rice grains from unfull rice grains is increased through multiple tiered separation, which facilitates the improvement of the screening rate when the rice grains enter the separation box 1 and are screened by the blower 9.
[0033] Reference Figure 1 ,Figure 2 , Figure 4 , Figure 5 , Figure 6 , Figure 7 , Figure 8 An inlet hole 10 is provided near the center of the upper end face of the separation box 1. An oblique hole 14 is provided on both sides of the separation box 1 near the front. A multi-hole baffle plate 3 is movably fitted between the two oblique holes 14. A first port 11 is provided near the center of the inner bottom surface of the separation box 1. A second port 12 is provided near the front of the inner bottom surface of the separation box 1. A slider 13 is fixedly connected to the inner bottom surface of the separation box 1 near the second port 12. Two fixing mechanisms 4 are respectively set on the lower sides of the diversion box 7. The fixing mechanism 4 includes a connecting rod 403. A fixing block 402 is fixedly connected to the center of the top oblique surface of the connecting rod 403. A connecting hole 401 is provided on one side of the fixing block 402. Connecting blocks 404 are fixedly connected to the top, bottom and center of the bottom oblique surface of the connecting rod 403. The outer surface of the connecting block 404 is movably fitted into the hole in the locking block 20.
[0034] Specifically, after being separated, the rice grains enter the separation box 1. The airflow generated by the blower 9 blows away the lighter, less plump rice grains, while the plump rice grains, due to their greater weight, are discharged from the first port 11. The less plump rice grains that are blown away will come out from the second port 12 through the cooperation of the porous baffle plate 3 and the slider 13, so they will not be blown everywhere. The porous baffle plate 3 has multiple small holes for air to pass through. The porous baffle plate 3 is inserted into the separation box 1 through the oblique hole 14, and can be removed for cleaning if it is not in use.
[0035] It should be noted that the hair dryer 9 is existing technology, and its specific structure will not be described in detail here.
[0036] Working principle: A large amount of rice is fed into the feeding box 5. The output of the drive motor 8 generates power, causing the threaded column 6 to rotate. The rice is then conveyed in an orderly manner from both sides to the diversion box 7 through the threads on the threaded column 6. The first diversion plate 15, the second diversion plate 16, and the third diversion plate 17 are oriented differently, causing the rice to slide in different directions on the guide plate 18. The guide plate 18 has multiple rectangular holes for separating plump and unplump rice. Through multiple stages of separation, the difference between plump and unplump rice is increased. The separation rate of the rice facilitates the improvement of the screening rate when the rice enters the separation box 1 and is screened by the blower 9. After being separated, the rice enters the separation box 1. The airflow generated by the blower 9 blows away the lighter, less plump rice, while the plump rice, due to its greater weight, is discharged from the first port 11. The less plump rice that is blown away will come out from the second port 12 through the cooperation of the porous baffle plate 3 and the slider 13, preventing it from being blown everywhere. The guide plate 18 and the porous baffle plate 3 can be removed from the equipment for cleaning.
[0037] Finally, it should be noted that the above description is only a preferred embodiment of the present utility model and is not intended to limit the present utility model. Although the present utility model has been described in detail with reference to the foregoing embodiments, those skilled in the art can still modify the technical solutions described in the foregoing embodiments or make equivalent substitutions for some of the technical features. Any modifications, equivalent substitutions, improvements, etc., made within the spirit and principles of the present utility model should be included within the protection scope of the present utility model.
