[0022] The technical solutions of the present utility model will be clearly and completely described below with reference to the accompanying drawings of the embodiments. Obviously, the described embodiments are only some embodiments of the present utility model, and not all embodiments. 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.

[0023] Please see Figures 1-5 This utility model discloses a drying device for producing fish feed, including a support platform 1, a positioning frame 7, an air distribution plate 18, and a feed box 3. The front end of the support platform 1 is provided with a control box 21. Multiple support legs are vertically arranged at the four corners of the support platform 1. A bearing plate 2 located below the support platform 1 is provided between the multiple support legs. The feed box 3 is placed on the bearing plate 2. The four corners of the bearing plate 2 are provided with limiting frames 22 that are penetrated by the support legs. The limiting frames 22 are provided with locking rods 23. The locking rods 23 are threadedly connected to the limiting frames 22, and one end abuts against the support legs.

[0024] The middle part of the support platform 1 is provided with a first empty slot, the material box 3 is located below the first empty slot, the positioning frame 7 is located above the first empty slot, the four corners of the positioning frame 7 are vertically provided with vertical rods 6, the bottom end of the vertical rods 6 is provided with a base 8 that is slidably connected to the support platform 1, the middle part of the positioning frame 7 is provided with a second empty slot, the inside of the second empty slot is provided with a moving plate 11, the lower end of the moving plate 11 is vertically provided with multiple material-pulling rods 15 that are inserted into the material box 3, and the positioning frame 7 is provided with a driving component for driving the moving plate 11 to move in the second empty slot;

[0025] The base 8 has multiple support rods 17 fixed to the upper end of the support platform 1 on both sides. The upper end of the air distribution plate 18 is provided with a drying fan 19. The air outlet end of the drying fan 19 is provided with an air outlet tube inserted into the air distribution plate 18. The lower end of the air distribution plate 18 is provided with multiple air outlet holes 20.

[0026] The upper end of the bearing plate 2 is provided with multiple positioning grooves 5, and the four corners of the lower end of the material box 3 are provided with positioning blocks 4 that are inserted into the positioning grooves 5.

[0027] First, the fish feed to be dried is loaded into the feed box 3. Then, the feed box 3 is placed on the support plate 2. At this time, the positioning blocks 4 at the four corners of the lower end of the feed box 3 will be precisely inserted into the positioning grooves 5 at the upper end of the support plate 2, so that the feed box 3 is stably placed on the support plate 2.

[0028] Subsequently, adjust the position of the limiting frame 22 through which the support legs penetrate the four corners of the bearing plate 2. After adjusting to the appropriate position, tighten the locking rod 23 on the limiting frame 22 so that one end of the locking rod 23 abuts against the support leg, thereby fixing the material box 3 at the specified height. At the same time, multiple material-pulling rods 15 at the lower end of the moving plate 11 below the positioning frame 7 will be inserted into the material box 3.

[0029] The drive assembly includes a motor 12 and a lead screw 13. Two guide rods 14 are symmetrically arranged in the second slot, penetrating the moving plate 11. The moving plate 11 and the guide rods 14 are slidably connected. The motor 12 is fixed on one side of the positioning frame 7. The lead screw 13 penetrates the middle part of the moving plate 11 and is threadedly connected to the moving plate 11. One end of the lead screw 13 is connected to the output end of the motor 12. The output end of the motor 12 is provided with a motor shaft that penetrates the positioning frame 7. One end of the lead screw 13 is connected to the motor shaft through a coupling. The other end of the lead screw 13 is rotatably connected to the positioning frame 7 through a bearing.

[0030] When the motor 12 on one side of the positioning frame 7 is started, the motor shaft at the output end of the motor 12 drives the lead screw 13 to rotate through the coupling. Since the lead screw 13 is threadedly connected to the moving plate 11, and the moving plate 11 is slidably connected to the two guide rods 14 symmetrically arranged in the second slot, the rotation of the lead screw 13 will drive the moving plate 11 to move laterally along the guide rods 14 in the second slot, thereby driving the feeding rod 15 to laterally move the fish feed in the feed box 3.

[0031] The upper end of the support platform 1 is symmetrically provided with two guide rails 10 in the first slot. The base 8 is provided with a guide groove 9 through which the guide rails 10 pass, and the base 8 is slidably connected to the guide rails 10. The cross section of the guide rails 10 is T-shaped.

[0032] At the same time, the cylinder 16 is activated. Under the action of the cylinder 16, the positioning frame 7 drives the base 8 to slide along the two T-shaped guide rails 10 set in the first symmetrical slot at the upper end of the support platform 1 through the vertical rods 6 at the four corners. The guide groove 9 on the base 8 cooperates with the guide rails 10 to ensure the stability of the movement, so that the positioning frame 7 moves vertically with the moving plate 11, and finally realizes the vertical sliding of the feeding rod 15 in the feed box 3. Through the horizontal and vertical movement of the feeding rod 15, the fish feed is moved in all directions and evenly.

[0033] Then, the drying fan 19 at the top of the air distribution plate 18 is started. The drying air generated by the drying fan 19 enters the interior of the air distribution plate 18 through the air outlet duct, and is then blown out through multiple air outlets 20 at the bottom of the air distribution plate 18 to dry the fish feed in the feed box 3. The support rods 17 on both sides of the base 8, which are fixed to the upper end of the support platform 1, provide stable support for the relevant components. The drying fan 19, cylinder 16 and motor 12 are controlled by the control box 21, thereby controlling the flow rate of the drying air and the movement state of the feed pusher 15, so that the fish feed will not spill out of the feed box 3.

[0034] When the fish feed is dried and needs to be unloaded, loosen the locking rod 23, slide the limit frame 22 downward, and the support plate 2 will descend with the feed box 3, making it easy to remove the feed box 3 from the support plate 2 and complete the unloading operation.

[0035] From the perspective of structural stability, the positioning block 4 at the lower end of the material box 3 and the positioning groove 5 at the upper end of the bearing plate 2 cooperate with each other to effectively prevent the material box 3 from shaking on the bearing plate 2 and ensure the stability of the material box 3. The T-shaped guide rail 10 at the upper end of the support platform 1 and the guide groove 9 on the base 8 are slidably connected, which greatly improves the stability of the positioning frame 7 when it moves under the drive of the vertical rod 6 and reduces shaking. The guide rod 14 in the second slot plays a good guiding role for the moving plate 11, ensuring that the moving plate 11 moves smoothly under the drive of the screw 13, thereby ensuring the stability of the movement of the feeding rod 15.

[0036] In terms of ease of operation, the setting of the limiting brackets 22 and locking rods 23 at the four corners of the bearing plate 2 makes it easy to adjust the height of the material box 3 according to actual needs. This facilitates the insertion of the material pusher 15 into the material box 3 and also makes it easy to remove the material box 3 from the bearing plate 2 by lowering the bearing plate 2 during unloading, thus simplifying the loading and unloading process.

[0037] In addition, the legs at the four corners of the support platform 1 provide a stable support foundation for the entire device. The support rod 17 provides auxiliary support for components such as the air distribution plate 18. The motor shaft is connected to the lead screw 13 through a coupling. The other end of the lead screw 13 is rotatably connected to the positioning frame 7 through a bearing, which ensures the stability and smoothness of the power transmission of the drive components, making the entire device more reliable in operation.
