[0032] Further, as Figures 5-6 shown, between the box body 10 and the drying cylinder 11, on the relative two sides of the support column 13, two air vents 25 are respectively provided. In the middle of the inside of each air vent 25, a fixing plate 26 is fixed. On the fixing plate 26, a second rotating shaft 27 is rotatably arranged. At the lower end of the second rotating shaft 27, a pneumatic wheel 28 is fixed. At the upper end of the second rotating shaft 27, a rotating plate 29 is fixed. A number of inclined air vents 30 are arranged at intervals on the rotating plate 29. The two air vents 25 are respectively close to the two heating blocks 24.
[0033] Further, as Figures 1-4 shown, the buffer assembly includes a fixed filter plate 34. The fixed filter plate 34 is obliquely fixed inside the box body 10. The fixed filter plate 34 is directly below the material discharge port 21. Above the fixed filter plate 34, a movable filter plate 35 is provided. The movable filter plate 35 slides and contacts inside the box body 10. Between the fixed filter plate 34 and the movable filter plate 35, a number of second springs 37 are provided.
[0034] Furthermore, as Figures 1-4 shown, a sponge plate 36 is provided on the upper side of the movable filter plate 35, and a recycling box 45 is provided inside the box body 10 below the fixed filter plate 34. The fixed filter plate 34 is inclined downward from the side facing the first rotating shaft 19 to the side of the conveying assembly from top to bottom, and the fixed filter plate 34 has the same inclination direction as the movable filter plate 35 and the sponge plate 36.
[0035] Furthermore, as Figures 1-4 shown, the conveying assembly includes two third rotating shafts 38. The two third rotating shafts 38 are spaced apart and rotatably connected inside the box body 10. A conveyor belt 39 is connected to the outside of the two third rotating shafts 38. A second motor 40 is installed on one side outside the box body 10, and the output end of the second motor 40 is connected to one of the third rotating shafts 38. A number of second through holes 46 are provided at intervals on the conveyor belt 39.
[0036] Furthermore, as Figures 1-4 shown, two guide plates 41 are respectively fixed on both sides above the conveying assembly inside the box body 10, and the inner side of one end of each guide plate 41 facing the buffer assembly is of an inclined surface structure.
[0037] Furthermore, as Figures 1-4 shown, a box door 43 is rotatably provided at one end inside the box body 10 deviating from the buffer assembly direction, and a collection box 42 is provided below one end of the conveying assembly inside the box body 10.
[0038] During use, the staff puts the fully washed cuttings into the funnel 12. The cuttings enter the inside of the drying cylinder 11 through the funnel 12, and the cuttings fall onto the upper side of the spiral plate 14. At this time, the first motor 20 is started to drive the first rotating shaft 19 to rotate. The first rotating shaft 19 rotates to drive the fan 22 to rotate. The fan 22 rotates to suck the air outside the box body 10 into the box body 10 through a number of air inlets 23. At this time, the two heating blocks 24 are started to heat the air in the box body 10. The heated air moves upward through the two air vents 25. Among them, the hot air flows in the air vents 25, thereby driving the pneumatic wheel 28 to rotate. The pneumatic wheel 28 rotates to drive the rotating plate 29 to rotate through the second rotating shaft 27. The rotating plate 29 rotates to stir the hot air moving upward in the air vents 25 through a number of inclined air vents 30, so that the hot air moves upward in a rotary manner, avoiding the straight upward movement of the hot air, thereby expanding the space for the hot air to flow, and then through a number of first through holes 15 on the spiral plate 14, so as to facilitate the movement of the hot air in the drying cylinder 11, so as to increase the contact area between the hot air and the cuttings and improve the drying effect of the cuttings.
[0039] Meanwhile, the rotation of the first rotating shaft 19 drives the rotation of the elliptical block 18. The rotation of the elliptical block 18 drives the lower end of the support column 13 through the contact between the outer side of the elliptical block 18 and the lower end of the support column 13, so as to drive the support column 13 to slide up and down reciprocally in the drying cylinder 11. The up and down movement of the support column 13 drives the two sliders 31 to slide up and down in the two chutes 32 respectively, and cooperates with the vertical sliding of the support column 13 in the sleeve 17, so that the support column 13 moves up and down stably in the drying cylinder 11; the up and down movement of the support column 13 drives the spiral plate 14 to move up and down in the drying cylinder 11. The up and down movement of the spiral plate 14 jitters and disperses the cuttings located above the spiral plate 14 to prevent the cuttings from accumulating together, so as to facilitate the full drying of each cutting; the up and down movement of the spiral plate 14 makes the cuttings move spirally downward along the spiral structure of the spiral plate 14, thereby prolonging the moving path of the cuttings in the drying cylinder 11. Then, a number of sponge bumps 16 on the spiral plate 14 block the cuttings, so that the cuttings move slowly on the upper side of the spiral plate 14, increasing the moving time of the cuttings on the guiding spiral plate 14, so as to improve the drying effect on the cuttings. And the cuttings move spirally downward on the upper side of the spiral plate 14 and cooperate with the continuously rotating upward movement of the hot air, so as to increase the contact area between the hot air and the cuttings and improve the drying effect on the cuttings.
[0040] After the cuttings are fully dried in the drying cylinder 11, they fall into the box body 10 through the feeding port 21. The cuttings fall onto the sponge plate 36, and first, a preliminary buffering effect is carried out through the elastic force of a number of second springs 37 on the moving filter plate 35, and then a further buffering effect is carried out through the elasticity of the sponge plate 36, so as to reduce the situation of cutting breakage. The broken parts of the cuttings fall into the recycling box 45 for storage through the through holes on the sponge plate 36, the moving filter plate 35 and the second springs 37. The cuttings move along the inclined guiding of the sponge plate 36 to the upper side of the conveyor belt 39; at this time, the second motor 40 is started to drive the rotation of one of the third rotating shafts 38. The rotation of one of the third rotating shafts 38 drives the rotation of the other third rotating shaft 38 through the movement of the conveyor belt 39. The movement of the conveyor belt 39 drives the movement of the cuttings. The movement of the cuttings is guided through the inclined surfaces on the two guiding plates 41, so that the cuttings move in the middle on the upper side of the conveyor belt 39, so as to facilitate the full analysis of the cuttings by the analyzer body 44; the cuttings move to the lower part of the analyzer body 44, and the analyzer body 44 analyzes the cuttings; the analyzed cuttings are conveyed to the collection box 42 for storage through the conveying component. Finally, the staff opens the box body 10 by rotating the box door 43 and takes out the cuttings in the collection box 42 for centralized treatment.
[0041] Although the embodiments of the present invention have been shown and described, for those of ordinary skill in the art, it can be understood that various changes, modifications, substitutions and variations can be made to these embodiments without departing from the principle and spirit of the present invention. The scope of the present invention is limited by the appended claims and their equivalents.
