Thus, features defined as "first", "second", and the like may explicitly or implicitly include one or more of the features. In the description of the present invention, unless otherwise specified, "multiple" means two or more.

[0027] In the description of the present invention, it should be noted that, unless otherwise clearly specified and limited, the terms "installed", "connected", and "connected" should be understood in a broad sense, for example, it can be a fixed connection, a detachable connection, or an integral connection; it can be a mechanical connection or an electrical connection; it can be a direct connection, or it can be indirectly connected through an intermediate medium, or it can be the internal communication of two components. For ordinary technicians in this field, the specific meanings of the above terms in the present invention can be understood by specific circumstances.

[0028] The present invention will be described in detail below with reference to the accompanying drawings and in conjunction with embodiments.

[0029] Example 1: Please refer to Figure 1-3 A corn drying device includes an equipment support 1, the equipment support 1 includes a horizontal bottom plate and a vertical side plate vertically fixed on the horizontal bottom plate, and an electric control box for controlling the entire equipment is connected to the vertical side plate. A drying cylinder 2 is rotatably connected to the equipment support 1, and the drying cylinder 2 is rotatably connected to the vertical side plate, and the rotation center of the drying cylinder 2 is perpendicular to the vertical side plate. The drying cylinder 2 is used to dry corn, and a feed hole for placing the corn inside the equipment support 1 is opened on the cylinder wall. At the same time, in order to prevent the corn from spilling during the rotary drying process, a cover plate for closing the feed hole is also provided on the outside of the feed hole. The cover plate only needs to cover the feed hole, and there is no need to seal it, so that there is a gap for the drying airflow to overflow during the drying process.

[0030] The equipment support 1 is also connected with a rotary drive assembly 3 for driving the drying cylinder 2 to rotate. The rotary drive assembly 3 is used to drive the drying cylinder 2 to rotate, so that the corn inside the drying cylinder 2 moves continuously inside the drying cylinder 2 to improve the uniformity of drying. The drying tube 4 is rotatably connected inside the drying cylinder 2, and air holes 5 are evenly distributed outside the drying tube 4. A hot air blower 6 is fixedly connected to the equipment support 1, and the drying tube 4 is connected to the hot air blower 6 through a connecting pipe. After placing the corn inside the drying cylinder 2, the hot air blower 6 can be turned on, and the rotary drive assembly 3 is turned on at the same time. The rotary drive assembly 3 drives the drying cylinder 2 to rotate, and the hot air blower 6 is connected to the inside through the connecting pipe, and the air flow of hot air is blown into the drying cylinder 2 through the air holes 5. The inner wall of the drying cylinder 2 is also fixedly connected with a drying auxiliary mechanism 7. The drying auxiliary mechanism 7 further drives the corn structure position to change, so that the uniformity of drying is guaranteed. Relative rotation can be generated between the drying tube 4 and the drying cylinder 2.

[0031] Example 2: Please refer to Figure 3In this embodiment, a rotary drive assembly is specifically disclosed. The rotary drive assembly 3 includes a drive motor 8 fixedly connected to the equipment bracket 1, the drive motor 8 is fixed to the vertical side plate, and a transmission shaft 9 is fixedly connected to the rotor of the drive motor 8, and the drying cylinder 2 is driven to rotate by the transmission shaft 9, thereby realizing a transmission connection between the transmission shaft 9 and the drying cylinder 2.

[0032] The driving shaft 9 is fixedly connected to the outside with a driving pulley 10, and the drying cylinder 2 is fixedly connected to the outside with a driven pulley 11, and the driving pulley 10 and the driven pulley 11 are driven by a transmission belt 12. The driving shaft 9 and the drying cylinder 2 can be driven by the transmission belt 12 to achieve synchronous rotation, and power transmission can also be achieved through other transmission methods such as gears or sprockets. Although the drive motor 8 can also be directly connected to the drying cylinder 2, the motor shaft is subject to greater force and is not suitable for direct connection. In addition, the power transmission of the drive motor 8 can also synchronously realize some functions of the following embodiments.

[0033] Example 3: Please refer to Figure 3-7 This embodiment specifically discloses the following technical features: the drying auxiliary mechanism 7 includes a plurality of elastic connecting frames 13 fixed to the inner wall of the drying cylinder 2, a sliding magnetic block 14 is slidably connected inside the elastic connecting frame 13, the sliding magnetic block 14 slides along the radial direction of the drying cylinder 2, a mixing shaft 15 is rotatably connected to the sliding magnetic block 14, the axis of the mixing shaft 15 is parallel to the axis of the drying tube 4, a plurality of stirring rods 16 are evenly and fixedly connected to the outer side of the mixing shaft 15, and a driving magnetic block 17 for driving the sliding magnetic block 14 to move is also provided on the equipment bracket 1.

[0034] During the sliding process of the sliding magnetic block 14, the stirring rod 16 and the position of the rotation center of the drying cylinder 2 are driven to change, so that the internal corn can be stirred. The sliding magnetic block 14 changes its position under the driving force of the outer driving magnetic block 17. During the rotation of the drying cylinder 2, the sliding magnetic blocks 14 at different positions will rotate to the bottom, thereby generating magnetic attraction or magnetic repulsion with the driving magnetic block 17 on the equipment bracket 1 to change the position of the sliding magnetic block 14. Since the corn is stirred, it is recommended to use a strong magnet to provide sufficient driving force. The driving magnetic block 17 is fixedly connected to the horizontal bottom plate of the equipment bracket 1. When fixed on the equipment bracket 1, the sliding magnetic block 14 will change its position every time it rotates to this position.

[0035] In addition, the driving magnetic block 17 can also generate force with the sliding magnetic block 14 in other ways. For example, an incomplete active gear 21 is fixedly connected to the outside of the transmission shaft 9, and a sliding member 22 is slidably connected to the equipment bracket 1. The sliding member 22 is a hollow structure, and the upper and lower sides of the inner side of the sliding member 22 are fixedly connected with transmission teeth 23. The incomplete gear alternately meshes with the upper and lower transmission teeth 23, and the driving magnetic block 17 is fixed to the top of the sliding member 22. In this embodiment, the driving motor 8 drives the incomplete active gear 21 to rotate, and the teeth of the incomplete active gear 21 will alternately mesh with the upper and lower transmission teeth 23 during the rotation process. Thereby driving the position of the sliding member 22 to continuously change, the driving magnetic block 17 fixedly connected to the sliding member 22 will continuously change its position forward and backward, and realize the different position matching with the sliding magnetic block 14, and finally make the position of the sliding magnetic block 14 change accordingly according to the change of the driving magnetic block 17. In order to ensure the normal operation between the sliding magnetic block 14 and the driving magnetic block 17, the drying cylinder 2 should not be made of iron or other materials that affect the transmission of magnetic force, and non-toxic polymer materials are preferred.

[0036] Example 4: See Figure 4-5 In this embodiment, the following technical means are specifically disclosed: the outer side of the mixing shaft 15 is fixedly connected with a driving block 18, the outer side of the driving block 18 is rotatably connected with a transmission A rod 19, the other end of the transmission A rod 19 is rotatably connected with a transmission B rod 20, and the transmission B rod 20 is fixedly connected to the drying tube 4. The mixing shaft 15 continuously changes its relative position with the drying tube 4, thereby synchronously driving the specific position states of the transmission A rod 19 and the transmission B rod 20 to change. In this process, since the drying tube 4 cannot change its position and can only rotate around its axis, the direction of the air hole 5 opened on the outer side of the drying tube 4 is continuously changed. Since the angle of the hot air flow is continuously changed, the existence of drying dead corners is avoided, and the drying uniformity is also significantly improved.

[0037] The elastic connection frame 13 includes a guide bracket 24 fixedly connected to the inner wall of the drying cylinder 2, a guide groove 25 is provided on the inner side of the guide bracket 24, and the sliding magnetic block 14 is slidably connected in the guide groove 25. A spring 26 is fixedly connected between the sliding magnetic block 14 and the guide bracket 24, and the axis of the spring 26 is the same as the sliding direction of the sliding magnetic block 14. The connection method of the elastic connection frame 13 can guide the sliding magnetic block 14, and is not limited to the connection method disclosed in this application. For example, if the guide bracket 24 is not used, but the sliding magnetic block 14 is directly connected through the spring 26, the sliding magnetic block 14 will change its position under the action of the driving magnetic block 17, but the position change has a certain randomness. Each group of the elastic connection frames 13 is provided with two, which are symmetrically arranged inside the drying cylinder 2, and the driving magnetic blocks 17 are provided with two, which are respectively located below the corresponding elastic connection frames 13. The two elastic connecting frames 13, the driving magnetic block 17 and the sliding magnetic block 14 are symmetrically arranged so that the forces at both ends of the mixing shaft 15 are balanced, and the above-mentioned contents can be better realized.

[0038] Example 5: See Figure 2 or Figure 3 , this embodiment also records the following technical scheme: the equipment bracket 1 is slidably connected to a guide rod 27, and a shielding plate 28 is fixedly connected to the upper end of the guide rod 27. The shielding plate 28 cooperates with the end of the drying tube 4 away from the hot air blower 6 to cover the end of the drying tube 4 when sliding. A cam 29 is fixedly connected to the end of the transmission shaft 9, and the lower end of the guide rod 27 is against the cam 29, and the longitudinal height changes during the rotation of the cam 29.

[0039] During the rotation of the transmission shaft 9, the cam 29 can be driven to rotate synchronously. The cam 29 drives the guide rod 27 to change its position, so that the shielding plate 28 moves up and down, and the end of the drying tube 4 is periodically shielded. At this time, since the airflow discharged from the end is completely blocked, the airflow will be discharged through the gaps in the wall of the drying tube 2. Due to the increase in discharge resistance, more hot air can pass through the inside of the drying tube 2, thereby improving the drying efficiency. Since it is a periodic shielding, the corn will not be over-dried. The bottom of the guide rod 27 can be rotatably connected to the roller so that it can roll in contact with the cam 29 during the contact process to avoid excessive wear of the guide rod 27. The guide rod 27 is against the cam 29 under the action of gravity, and a reset structure can also be provided, such as a spring to ensure that the guide rod 27 and the cam 29 can maintain a state of being against each other.

[0040] It will be apparent to those skilled in the art that the invention is not limited to the details of the exemplary embodiments described above and that the invention can be implemented in other specific forms without departing from the spirit or essential features of the invention. Therefore, the embodiments should be considered exemplary and non-limiting in all respects, and the scope of the invention is defined by the appended claims rather than the foregoing description, and it is intended that all variations falling within the meaning and scope of the equivalent elements of the claims be included in the invention. Any reference numeral in a claim should not be considered as limiting the claim to which it relates.

[0041] In addition, it should be understood that although the present specification is described according to implementation modes, not every implementation mode contains only one independent technical solution. This description of the specification is only for the sake of clarity. Those skilled in the art should regard the specification as a whole. The technical solutions in each embodiment may also be appropriately combined to form other implementation modes that can be understood by those skilled in the art.
