[0017] As Figures 1 to 8 shown, the automatic adjusting and circulating solar drying device includes a frame 5, a drying chamber 15, a heat collection box, an adjusting assembly and a photovoltaic assembly. As Figure 1 shown, the frame 5 and the drying chamber 15 are fixedly connected, and the heat collection box is movably arranged above the frame 5. Specifically, the frame 5 is of a frame structure and is welded by profiles, and the drying chamber 15 is arranged on one side of the frame 5. As Figure 6As shown in the figure, the drying chamber 15 includes an upper front plate 153, a lower front plate 154, a bottom plate 155, side plates 156, a rear plate 157, a top plate 158, and an air outlet 159. Among them, the upper front plate 153, the lower front plate 154, the bottom plate 155, the side plates 156, the rear plate 157, and the top plate 158 form the respective surfaces of the drying chamber, so that the drying chamber 15 encloses a closed box-like structure. The air outlet 159 is located on the top plate 158. Between the upper front plate 153 and the lower front plate 154 is an air inlet 152. On the left and right side plates 156, two groups of adjusting plates 151 are fixed and arranged up and down. Each group includes two adjusting plates 151 arranged symmetrically left and right. The wet air in the drying chamber 15 is discharged through the air outlet 159 as Figure 1 , Figure 3 As shown in the figure, the heat collection box includes a heat collection box front plate 2, a heat collection box left plate 40, a heat collection box bottom plate 42, and a heat collection box right plate 44. The heat collection box front plate 2, the heat collection box left plate 40, the heat collection box bottom plate 42, and the heat collection box right plate 44 form the respective surfaces of the heat collection box, so that the heat collection box forms a cuboid structure with an open top surface and an open rear surface. A heat collection plate 43 is provided at the bottom of the heat collection box, and the heat collection plate is located inside the heat collection box. A glass 1 is provided at the top of the heat collection box. The setting of the glass 1 enables sunlight to shine into the heat collection box. The open rear surface of the heat collection box is used to connect with the air inlet 152 to realize the connection between the heat collection box and the drying chamber 15. As Figure 3 As shown in the figure, at the rear end of the heat collection box, that is, at the second end of the heat collection box, a heat collection box rotating shaft 41 is provided. Through the heat collection box rotating shaft 41, the hinge connection between the second end of the heat collection box and the drying chamber 15 is realized. As Figure 1 As shown in the figure, at the front end of the heat collection box, that is, at the first end of the heat collection box, there is an inlet fan 6. When the inlet fan 6 works, it sucks external air into the heat collection box. The heat collection plate absorbs solar heat and transfers it to the air in the heat collection box to generate hot air. The hot air enters the drying chamber 15 through the air inlet 152 to dry the materials located in the drying chamber 15.

[0018] As Figure 1 As shown in the figure, the adjusting assembly is located between the frame 5 and the heat collection box and is used to adjust and fix the inclination angle of the heat collection box. As Figure 4 As shown in the figure, the adjusting assembly includes a transverse guide rail 8 and an adjusting drive mechanism. The transverse guide rail 8 is slidably connected to the frame 5. The adjusting drive mechanism is used to drive the movement of the transverse guide rail 8. The transverse guide rail 8 has a vertical long groove 851. As Figure 3 As shown in the figure, a guide rotating shaft 38 is fixed at the bottom of the first end of the heat collection box. A guide wheel 39 is rotatably installed on the guide rotating shaft 38. As Figure 8As shown in the figure, the guide wheel 39 extends into the long groove 851 and is in rolling cooperation with the long groove 851, that is, the guide wheel 39 rolls in the long groove 851. When the transverse guide rail 8 moves, the guide wheel 39 rolls in the long groove 851, and then the height of the guide wheel 39 relative to the transverse guide rail 8 changes, and then the inclination angle of the heat collection box changes, realizing the adjustment of the inclination angle of the heat collection box to adapt to the sun irradiation at different heights.

[0019] As the first embodiment of the adjustment driving mechanism, as Figure 4 、 Figure 8 shown, the adjustment driving mechanism includes an adjustment motor 47, an adjustment reducer 9 and a lead screw 7.

The lead screw 7 is rotatably installed on the frame 5 through a lead screw bearing 3, and the lead screw 7 is fixedly connected to the output end of the adjustment reducer 9 through an adjustment coupling 48. The transverse guide rail 8 is in threaded cooperation with the lead screw 7. After starting the adjustment motor 47, deceleration is carried out through the adjustment reducer 9, so that the lead screw 7 rotates slowly. When the lead screw 7 rotates, it drives the movement of the transverse guide rail 8. As Figure 5 shown, as an implementation manner of the transverse guide rail 8, the transverse guide rail 8 includes a support plate 84, a guide rail fixing plate 83, a track plate 85, a sliding shaft 82 and a sliding wheel 81.

As Figure 4 、 Figure 8 shown, the guide rail fixing plate 83 is provided with a lead screw nut 45 for threaded cooperation with the lead screw 7, so as to facilitate the threaded cooperation between the transverse guide rail 8 and the lead screw 7. The fixed shaft 82 is fixedly connected to the vertical part of the support plate 84, and the sliding wheel 81 is rotatably installed on the fixed shaft 82.

[0020] As the second embodiment of the adjustment driving mechanism, the adjustment driving mechanism includes an electric telescopic rod. The main body of the electric telescopic rod is fixedly connected to the frame 5, and the telescopic rod of the electric telescopic rod is fixedly connected to the transverse guide rail 8. Compared with the first embodiment, the adjustment driving mechanism of the second embodiment has a simpler structure. The structure of the transverse guide rail 8 matched with the second embodiment is simpler, and only needs to have a structure for sliding connection with the longitudinal guide rail 4 and sliding connection with the guide wheel 39.

[0021] The drying chamber has material circulation components, such as Figure 2 As shown, the material circulation assembly includes a drying chamber bracket 35, a circulating chain transmission mechanism, a lifting material box 36, a circulating fan 25 and a circulating drive mechanism. The drying chamber bracket 35 is movably arranged inside the drying chamber 15 to facilitate the drying chamber bracket 35 to enter and exit the drying chamber 15. In order to facilitate the movement of the drying chamber bracket 35, the drying chamber 15 and the frame 5, as shown in FIG. Figure 1 , Figure 2 As shown, universal wheels 27 are provided at the bottom of the frame 5, the drying chamber 15 and the drying chamber bracket 35. There are two symmetrically arranged circulating chain transmission mechanisms, which include a circulating chain 29 and four circulating sprockets 28 for chain transmission. The circulating sprockets 28 are rotatably mounted on the drying chamber bracket 35. The four circulating sprockets 28 are located at the four vertices of a rectangle, so that the circulating chain 29 is supported in a rectangular shape. In order to realize the synchronous action of the two circulating chain transmission mechanisms, there is a driven shaft 30 between two corresponding circulating sprockets 28 on the two circulating chain transmission mechanisms. The driven shaft 30 is rotatably mounted on the upper part of the drying chamber bracket 35. One of the circulating sprockets 28 on one of the circulating chain transmission mechanisms is fixed to the first end of the driven shaft 30, and the corresponding circulating sprocket 28 on the other circulating chain transmission mechanism is fixed to the second end of the driven shaft 30. When the driven shaft 30 rotates, the circulating sprockets 28 on the two circulating chain transmission mechanisms rotate synchronously.

[0022] The lifting box 36 is located between the circulating chains 29 of the two circulating chain transmission mechanisms and is fixedly connected to the circulating chains 29. Figure 7 As shown, the lifting material box 36 includes a box body 364, a fixed shaft 363 and a material support plate 362. The fixed shaft 363 is fixed at both ends of the box body 364. The end of the fixed shaft 363 has a clamp 365 for fixedly connecting with the chain link of the circulating chain 29. The clamp 365 is a "]"-shaped structure, and a mounting hole is provided on the clamp 365. The material support plate 362 is rotatably mounted on the fixed shaft 363. The material support plate 362 has multiple mounting angles, and the mounting angles have rolling wheels 361, as shown in FIG. Figure 2 As shown, the drying chamber bracket 35 has a circulating guide plate 24, and the circulating guide plate 24 has an annular groove, and the rolling wheel 361 extends into the annular groove and rolls along the annular groove. When the circulating sprocket 28 rotates, it drives the circulating chain 29 to move, and then drives the lifting box 36 to move along the annular groove to achieve circulating movement. Figure 9 As shown, the circulating chain 29 includes inner links 291 and outer links 293 arranged alternately, and a link support 292 is provided on the outer link 293. The setting of the link support 292 facilitates the fixed connection and assembly of the clamp 365 and the circulating chain 29, and the link support 292 is provided with a round hole matching the mounting hole on the clamp 365. The box body 364 of the lifting box 36 is evenly distributed with small holes to facilitate the passage of hot air.

[0023] The circulating drive mechanism is located on the drying chamber support 35 and is used to drive the rotation of the circulating sprocket 28. As Figure 2 shown, the circulating drive mechanism includes a circulating motor 37, a circulating reducer 20, a main shaft 23, and a driving chain transmission mechanism 22. The circulating motor 37 and the circulating reducer 20 are both fixed on the drying chamber support 35.

The output end of the circulating reducer 20 is fixedly connected to the main shaft 23 through a circulating coupling 21. The main shaft 23 is rotatably installed on the upper part of the drying chamber support 35. The driving chain transmission mechanism 22 includes a driving sprocket and a driving chain. There are two driving sprockets. The first driving sprocket is fixed at one end of the main shaft 23, and the second driving sprocket is fixed at one end of the driven shaft 30. The driving chain is arranged between the two driving sprockets. After starting the circulating motor 37, the main shaft 23 rotates slowly under the speed reduction effect of the circulating reducer 20, and then drives the rotation of the driven shaft 30 through the driving chain, and then drives the synchronous operation of the two circulating chain transmission mechanisms.

[0024] As another implementation manner of the circulating drive mechanism, there are two driving chain transmission mechanisms 22, and the two driving chain transmission mechanisms 22 respectively correspond to the two circulating chain transmission mechanisms one by one. At this time, one of the circulating sprockets 28 of the circulating chain transmission mechanism is rotatably connected to the upper part of the drying chamber support 35 through the driven shaft 30, and the other three circulating sprockets 28 of the circulating chain transmission mechanism are rotatably connected to the upper part of the drying chamber support 35 through the sprocket shaft 32. For the convenience of assembly, a first bearing support 31 and a second bearing support 34 are fixed on the drying chamber support 35. The driven shaft 30 is rotatably installed on the first bearing support 31, and the sprocket shaft 32 is rotatably installed on the second bearing support 34. For this reason, rolling bearings 33 are provided on the first bearing support 31 and the second bearing support 34.

The first driving sprockets of the two driving chain transmission mechanisms 22 are fixed at the corresponding ends of the main shaft 23, and the second driving sprockets of the driving chain transmission mechanism 22 are fixedly connected to the corresponding driven shafts 30. A driving chain is arranged between the two driving sprockets of the driving chain transmission mechanism 22. When the main shaft 23 rotates, the driving sprockets at both ends of the main shaft 23 rotate synchronously, and then the two driven shafts 30 rotate synchronously, and then the two circulating chain transmission mechanisms operate synchronously.

[0025] As Figure 2 shown, the circulating fan 25 is located at the lower part of the drying chamber support 35. The lower part of the drying chamber support 35 has a fan fixing plate 26. The fan fixing plate 26 is fixedly connected to the drying chamber support 35. The circulating fan 25 is installed on the fan fixing plate 26. The inlet fan 6 sucks external air into the heat collecting box, and the hot air in the heat collecting box enters the drying chamber 15 and circulates in the drying chamber 15 under the action of the circulating fan 25.

[0026] The photovoltaic module converts solar energy into electrical energy to provide electrical energy for the entire device. The photovoltaic module includes a main photovoltaic panel 13. As Figure 1 shown, the upper sliding rod 14 and the lower sliding rod 12 are hinged to the back of the main photovoltaic panel 13. The end of the upper sliding rod 14 penetrates through the adjusting plate 151 above the drying chamber 15, and the end of the lower sliding rod 12 penetrates through the adjusting plate 151 below the drying chamber 15. Both the upper sliding rod 14 and the lower sliding rod 12 are in a "]" shape structure. By adjusting the relative positions of the upper sliding rod 14 and the lower sliding rod 12 extending into the adjusting plate 151, the inclination angle of the main photovoltaic panel 13 can be adjusted to adapt to the sunlight and ensure the photoelectric conversion efficiency of the main photovoltaic panel 13. The main photovoltaic panel 13 is arranged on the side wall of the drying chamber 15. In addition, the photovoltaic module further includes a secondary photovoltaic panel 19, and the secondary photovoltaic panel 19 is fixed to the top of the drying chamber 15 by the unequal-length first column 17 and the second column 18. The bottoms of the first column 17 and the second column 18 have photovoltaic fixing plates 16, and the photovoltaic fixing plates 16 are fixed to the top plate 158 of the drying chamber 15. The lengths of the first column 17 and the second column 18 are unequal, so that the secondary photovoltaic panel 19 is inclined. The setting of the secondary photovoltaic panel 19 provides auxiliary electrical energy for the entire device.

[0027] As Figure 1 shown, a battery base 10 is provided on the frame 5, and a battery box cover 11 is provided on the battery base 10. As Figure 4 shown, a battery 46 is arranged in the battery base 10, and the battery 46 is used to provide electrical energy for the adjusting assembly. The battery base 10 is used to accommodate and place the battery 46, and the battery box cover 11 is used to protect the battery 46.

[0028] The working principle of the present invention is described below: (1) Place the material on the lifting material box 36, push the drying bracket 35 into the drying chamber 15, and close the hatch of the drying chamber 15; (2) Start the inlet fan 2 and the circulation fan 25, introduce external air into the heat collection box, heat it in the heat collection box and then become hot air and enter the drying chamber 15. Under the action of the circulation fan 25, the hot air flows from bottom to top to dry the material on the lifting material box 36; (3) At the same time, start the circulation motor 37 to make the lifting material box 36 move in a cycle in the drying chamber 15.

[0029] Through the setting of the material circulation component, the material moves cyclically in the drying chamber 15. During the movement, all the materials accumulated in the lifting box 36 can come into contact with the hot air, and thus the drying effect is good. In addition, the moving lifting box 36 can avoid mutual occlusion. Therefore, on the premise of placing more lifting boxes in the drying chamber 15, it can ensure that the materials in each lifting box 36 can come into contact with the hot air. By adjusting the inclination angle of the heat collection box through the adjustment component to adapt to the illumination, the heat collection efficiency of the heat collection box can be improved. By adjusting the relative positions among the upper sliding rod 14, the lower sliding rod 12 and the adjustment plate 151, the inclination angle of the main photovoltaic panel 13 can be adjusted, and thus the photoelectric conversion efficiency of the main photovoltaic panel 13 can be ensured.
