Technical Field
[0001] This utility model relates to the field of dryer technology, specifically to a discharge device for a dryer. Background Technology
[0002] Chinese patent document CN212512396U discloses a dryer unloading device, including a support base. A dryer is fixedly connected to the middle of the support base. A hot air blower is arranged on the top of the support base relative to the right side of the dryer. A connecting frame is arranged on the top middle of the dryer. A first motor is fixedly connected inside the connecting frame. The bottom of the first motor is rotatably connected to the inside of the dryer. The driven shaft is driven to rotate via a belt, thereby driving the reversing plate to rotate. When the reversing plate rotates counterclockwise, the upper side wall inside the movable frame contacts the upper surface of the reversing plate, thereby driving the movable frame to move upward. This causes the sliding rod to slide inside the connecting plate. When it moves to the highest point, the reversing plate continues to rotate. At this time, the movable frame separates from the reversing plate, and the reversing frame performs free fall motion, thereby driving the unloading hammer to hammer the dried material blocked inside the guide box, preventing the unloading device from being blocked and improving the unloading efficiency.
[0003] However, in the above-mentioned solutions and existing technologies, the unloading box is fixedly installed on the bottom guide pipe of the dryer. A rotating shaft is installed inside the unloading box, and an unloading plate is fixedly installed on the circumferential wall of the rotating shaft to assist in unloading. A rubber scraper is installed at the end of the unloading plate to clean the inner wall of the unloading box. During use, the rubber scraper wears down, which affects the cleaning effect of the inner wall of the unloading box. The entire unloading box needs to be disassembled to replace the rubber scraper, which is cumbersome and time-consuming, and affects the unloading efficiency of the dryer. Utility Model Content

[0025] To make the objectives, technical solutions, and advantages of this utility model clear and complete, the embodiments of this utility model will be further described in detail below with reference to the accompanying drawings. It should be understood that the specific embodiments described herein are only some, not all, embodiments of this utility model, and are merely used to explain the embodiments of this utility model. They are not intended to limit the embodiments of this utility model. All other embodiments obtained by those skilled in the art without creative effort are within the scope of protection of this utility model.
[0026] Please see Figures 1-9 The present invention provides the following two preferred embodiments:
[0027] Example 1: A discharge device for a dryer, comprising: a discharge box 2, which is fixedly installed at the bottom end of the dryer guide pipe 1; a rotating shaft 3 passing through both sides of the discharge box 2; a turntable 4 symmetrically fixedly sleeved on the circumferential wall of the rotating shaft 3; the turntable 4 being rotatably connected to the side wall of the discharge box 2; discharge plate grooves 5 equidistantly opened on the circumferential wall of the rotating shaft 3; a motor 27 fixedly installed on the side wall of the discharge box 2; the output end of the motor 27 being fixedly connected to the side wall of the rotating shaft 3; a discharge plate 6, which has a trapezoidal groove 7 at its end; a trapezoidal block 9 fixedly installed on the side wall of a rubber scraper 8; the trapezoidal groove 7 and the trapezoidal block 9 being inserted into each other; the side walls of the discharge plate 6 and the rubber scraper 8 being snapped into the side wall of the discharge box 2; the discharge plate 6 being inserted into the discharge plate groove 5; and the discharge plate 6 being installed on the rotating shaft 3 through a connecting assembly and an auxiliary assembly; the empty grooves 10 in the connecting assembly are equidistantly opened on the rotating shaft. Inside slot 10, a limiting block 11 is movably engaged with the slot 10. A positioning post 12 is fixedly sleeved on the limiting block 11. A spring 14 is sleeved on the positioning post 12, and the spring 14 is engaged with the limiting block 11. One end of the positioning post 12 passes through the unloading plate slot 5, and the other end of the positioning post 12 passes through the side wall of the rotating shaft 3 and is movably fitted with a ball bearing 13. An anti-slip ring platform 15 is fixedly sleeved on the circumferential wall of the rotating shaft 3. A semi-arc plate 17 is fixedly mounted on the side wall of the unloading box 2 and located around the anti-slip ring platform 15. A positioning groove 16 is opened on the side wall of the unloading plate 6 and is inserted into the positioning post 12. An external threaded disc 18 is fixedly mounted at the end of the semi-arc plate 17 and is engaged with the ball bearing 13. A square groove 19 is opened on the side wall of the external threaded disc 18, and the positioning post 12 is movably engaged in the square groove 19. Guide blocks 28 are symmetrically fixed on the inner walls of both sides of the unloading box 2.
[0028] In use, the rotating shaft 3 is rotated with the help of the anti-slip ring platform 15 until the compressed spring 14 returns to its original position and pushes the limiting block 11 to move, so that the positioning post 12 moves and engages with the square groove 19 to fix the position of the rotating shaft 3. At this time, the positioning post 12 retracts into the empty groove 10, and one of the unloading plate grooves 5 faces the bottom of the unloading box 2. The trapezoidal block 9 is inserted into the trapezoidal groove 7 so that the rubber scraper 8 is installed on the unloading plate 6. Then the unloading plate 6 is installed so that the two side walls of the unloading plate 6 engage with the guide block 28. The guide block 28 limits the unloading plate 6 to ensure that the unloading plate 6 is inserted into the unloading plate groove 5. The unloading plate 6 and the two side walls of the rubber scraper 8 engage with the inner side wall of the unloading box 2 to prevent the rubber scraper 8 from disengaging from the unloading plate 6. Press the positioning post 12. The limiting block 11 compresses the spring 14 until the positioning post 12 is inserted into the positioning groove 16 to fix the position of the unloading plate 6 and the rubber scraper 8. Then, the rotating shaft 3 is rotated to make the ball 13 engage with the side wall of the external threaded disc 18 until another positioning post 12 moves and engages with the square groove 19. The same method is used to connect and set multiple unloading plates 6 and rubber scrapers 8 to the rotating shaft 3 in sequence. When disassembling, the spring 14 pushes the limiting block 11 to move so that the positioning post 12 moves and engages with the square groove 19, and then the unloading plate 6 is unlocked, so that the unloading plate 6 and the rubber scraper 8 can be inserted and removed. The operation is simple and quick, and the rubber scraper 8 can be quickly replaced after wear to ensure the cleaning effect on the inner wall of the unloading box and avoid affecting the unloading efficiency of the dryer.
[0029] Example 2: Based on Example 1, the protrusion 20 in the auxiliary component is fixedly mounted on the side wall of the external threaded disc 18, and an internal threaded tube 22 is rotatably mounted on the periphery of the limiting disc 21. The internal threaded tube 22 is threadedly connected to the external threaded disc 18. A square hole 23 is opened on the side wall of the limiting disc 21, and the square hole 23 is inserted into the protrusion 20. A square block 24 is fixedly mounted on the side wall of the limiting disc 21 and is fitted into the square groove 19. A slot 25 is opened on the side wall of the protrusion 20, and a T-shaped pin 26 is inserted into the slot 25 and engaged with the limiting disc 21.
[0030] In use, after inserting multiple unloading plates 6 into the corresponding unloading plate slots 5, rotating the rotating shaft 3 causes all the balls 13 to engage with the external threaded disc 18, and then the square hole 23 engages with the protrusion 20. Next, rotating the internal threaded tube 22 ensures a tight threaded connection with the external threaded disc 18. The T-shaped pin 26 is then inserted into the slot 25, and the T-shaped pin 26 engages with the limiting disc 21, ensuring stable engagement between the square block 24 and the square slot 19, thereby ensuring that all the balls 13 are engaged during the rotation of the rotating shaft 3. All beads 13 can be engaged with the external threaded disc 18 and the square block 24 to prevent the positioning pin 12 from loosening when inserted into the positioning groove 16, thereby ensuring the installation stability of the unloading plate 6 and the rubber scraper 8. The operation is simple and quick. The motor 27 starts the rotating shaft 3 to rotate, which in turn drives the unloading plate 6 and the rubber scraper 8 to rotate. After the material in the dryer is dried, it falls into the unloading box 2 through the dryer guide pipe 1 at the bottom of the dryer body. The unloading plate 6 rotates to assist in unloading, and the rubber scraper 8 cleans the inner wall of the unloading box.
[0031] Although embodiments of the present invention have been shown and described, it will be understood by those skilled in the art that various changes, modifications, substitutions and alterations can be made to these embodiments without departing from the principles and spirit of the present invention, the scope of which is defined by the appended claims and their equivalents.
