[0026] The following is a clear and complete description of the technical solutions in the embodiments of the present invention in conjunction with the accompanying drawings. In the following description, many specific details are set forth to facilitate a full understanding of the present invention. However, the present invention can also be implemented in other ways different from those described herein, and those skilled in the art can make similar generalizations without violating the connotation of the present invention. Therefore, the present invention is not limited to the specific embodiments disclosed below.

[0027] like Figure 1 The figure is a side structural diagram of the peanut drying machine of the present invention. The peanut drying machine of the present invention is provided with a base 10, a heating device 20, an outer cylinder 30, an inner cylinder 40, a rotating device and a cleaning device. The inner cylinder 40 is sleeved in the outer cylinder 30. Please also refer to Figure 2 The figure is a partial structural diagram of the dryer. The outer peripheral wall of the inner drum 40 is perforated with a plurality of through holes 41. The rotating device is provided with a first driving motor (not shown in the figure), a rotating rod 51, a gear 52 and a gear ring 53. The output end of the first driving motor is axially connected to the rotating rod 51, the rotating rod 51 is connected to the central axis of the gear 52, the gear 52 is meshed with the gear ring 53, and the gear ring 53 is sleeved on the outer wall of any port of the inner drum 40. When the first driving device is started, the driving device drives the rotating rod 51 to rotate, thereby causing the gear 52 axially connected to the inner drum 40 to start rotating. The gear 52 and the gear ring 53 are in a cooperative relationship, which ultimately drives the gear ring 53 to rotate. The gear ring 53 is fixedly mounted on the outer wall of the inner drum 40, so that the inner drum 40 can rotate.

[0028] In addition, the inner drum 40 wall of the dryer of the present invention is provided with a plurality of spiral conveying pieces (not shown in the figure), such as Figure 1 A feed port 42 is provided at either end of the inner cylinder 40 shown. After the inner cylinder 40 adjusts its rotation direction, the feed port 42 is converted into a discharge port. Furthermore, an exhaust port (not shown in the figure) is provided on the outer cylinder 30. The exhaust port is used to discharge hot air or dust in the outer cylinder 30. It should also be added that in this embodiment, a plurality of positioning wheels 72 located on the same cross-sectional circle are fixedly provided on the inner wall of the outer cylinder 30, and a positioning ring 71 is provided on the outer peripheral wall of the inner cylinder 40 relative to these positioning wheels 72. The positioning ring 71 is fixed on the outer peripheral wall of the inner cylinder 40, and the positioning wheel 72 is engaged with the positioning ring 71, thereby achieving the purpose of stable rotation of the inner cylinder 40 in the outer cylinder 30.

[0029] During actual use of the dryer of the present invention, the heating device 20 is first turned on. The heating device 20 can be a gas heater, i.e., by providing a gas port to heat the bottom of the outer cylinder 30, or an electric heating device, i.e., by providing a plurality of electric heating elements on the outer wall of the outer cylinder 30. Alternatively, the heating device can be a heat supply device that delivers hot air heated to a certain temperature into the interior of the outer cylinder 30. Any device that can achieve the heating and drying function is suitable. After the heating device 20 is activated to complete preheating, the moist peanuts are placed into the inner cylinder 40 through the feed port 42. The first drive device is activated to achieve stable rotation of the inner cylinder 40, thereby uniformly heating and drying the peanuts within the inner cylinder 40. After the peanuts are thoroughly dried, the rotation direction of the first drive device can be adjusted to reverse the rotation direction of the inner cylinder 40. At this point, the feed port 42 functions as a discharge port, thereby enabling the collection of the dried peanuts.

[0030] Please refer to Figure 2 and Figure 3 As shown, the dryer of the present invention is also provided with a cleaning device, which is located between the inner drum 40 and the outer drum 30, and is used to clean the through hole 41 of the inner drum 40. Specifically, the cleaning device is provided with a cleaning ring 61, a threaded rod 62, a positioning rod, a second drive motor and a plurality of mounting plates 63. Connecting plates 64 are provided at the upper and lower vertices of the outer peripheral wall of the cleaning ring 61, and the threaded rod 62 and the positioning rod are respectively passed through the connecting plates 64, wherein the positioning rod is not drawn, and it is parallel to the threaded rod 62, and the difference in structure between the positioning rod and the threaded rod 62 is that the outer wall of the positioning rod is smooth and no threaded structure is provided, while the threaded rod 62 is screwed to the connecting plate 64.

[0031] The output end of the second drive motor is axially connected to either end of the threaded rod 62. The second drive motor is located outside the outer cylinder 30. The two ends of the threaded rod 62 and the connecting plate 64 are fixed to the inner wall of the outer cylinder 30 through the mounting plate 63. The inner wall of the cleaning ring 61 is surrounded by a number of cleaning brush bodies 611. The cleaning brush bodies 611 are made of a high-temperature resistant and deformable material. During the cleaning process of the dryer of the present invention, the second drive motor is started, which drives the threaded rod 62 to rotate, and then drives the connecting plate 64 to move, and finally realizes that the cleaning ring 61 is arranged on the outer periphery of the inner cylinder 40 and moves. The cleaning brush body 611 arranged on the inner side of the cleaning ring 61 can clean the impurities in the through hole 41 on the inner cylinder 40, thereby realizing dead-angle cleaning of the inner cylinder 40.

[0032] Through the above technical solution, the peanut dryer of the present invention is provided with a cleaning device on the outer periphery of the inner cylinder 40. The cleaning device can stably remove impurities on the inner cylinder 40 without affecting the drying progress, thereby improving product production efficiency and quality.

[0033] Obviously, the embodiments described are only some of the embodiments of the present invention, not all of them.
