[0002] With the rapid development of the mixing industry, cost reduction and efficiency improvement have become the goals pursued by the industry, which are particularly crucial and important. However, the traditional design method of the discharging door of the mixer restricts the improvement of the discharging efficiency and the operation convenience to a certain extent. Currently, most of the discharging doors widely used in the industry rely on the connecting rod connection and the pushing mechanism of the oil cylinder or the air cylinder to push the connecting rod to drive the opening and closing of the discharging door. This structure usually has a small opening and closing angle of the door. The existing design greatly limits the opening and closing angle of the discharging door. This limitation leads to unsmooth discharging process and low efficiency, and may even affect the quality and progress of the entire mixing operation. In view of this problem, the industry urgently needs a new type of discharging door design to break through the limitation of the opening and closing angle, improve the discharging efficiency, and optimize the operation convenience. Push the connecting rod to drive the opening and closing of the discharging door. This structure usually has a small opening and closing angle of the door. Summary of the Invention

[0021] The technical solutions in the embodiments of the present invention will be clearly and completely described below with reference to the accompanying drawings in the embodiments of the present invention. Obviously, the described embodiments are only a part of the embodiments of the present invention, rather than all the embodiments. All other embodiments obtained by those of ordinary skill in the art based on the embodiments of the present invention without creative efforts shall fall within the protection scope of the present invention.

[0022] Please refer to Figures 1-4 , the present invention provides a large-angle opening and closing discharge door device, which includes a storage tank 1. An arc plate 2 is fixed below the storage tank 1. A discharge opening 3 for discharging is provided on the surface of the arc plate 2. A fixed mounting bracket 4 is installed on the arc plate 2. A proximity switch mounting clip 5 is installed on the fixed mounting bracket 4. A proximity switch 6 is installed on the proximity switch mounting clip 5. A rotating shaft contact 7 is installed inside the proximity switch 6. An oil cylinder base fixing plate 8 is installed on one side of the arc plate 2. An oil cylinder base 9 is installed on the oil cylinder base fixing plate 8. An oil cylinder 10 is rotatably connected to the oil cylinder base 9 through a rotating pin;

[0023] Slide rail mounting plates 11 are installed on both sides of the discharge opening 3. Slide rails 12 are installed on the slide rail mounting plates 11. Slide blocks 13 slide on the slide rails 12. A rack 14 is installed on the slide block 13;

[0024] A rotating shaft fixing plate 15 is installed on one side of the discharge opening 3. Reinforcing ribs 16 are installed between the rotating shaft fixing plates 15. A bearing 17 is installed on the reinforcing ribs 16. A rotating shaft 18 is rotated through the bearing 17 on the reinforcing ribs 16. A gear 19 is installed on the outer side of the surface of the rotating shaft 18. A connecting rod 20 is installed on the inner side of the surface of the rotating shaft 18. A discharge door 21 is installed at one end of the connecting rod 20 away from the rotating shaft 18. By pouring materials into the storage tank 1 and rotating the discharge door 21, the discharge opening 3 can be opened or closed to discharge the storage tank 1.

[0025] Further, the size of the discharge door 21 is larger than that of the discharge opening 3. The rotary shaft 18, the connecting rod 20, and the discharge door 21 are fixedly connected. When the rotary shaft 18 rotates, the rotary shaft 18 can drive the discharge door 21 to rotate through the connecting rod 20. Therefore, the discharge opening 3 can be opened or closed, and the size of the discharge door 21 is larger than that of the discharge opening 3. When the discharge door 21 is closed, the edge of the discharge door 21 extends to the outside of the discharge opening 3 to improve the sealing performance of the discharge door 21 for the discharge opening 3.

[0026] Further, the gear 19 is fixedly connected to the rotary shaft 18. The gear 19 meshes with the rack 14. The rack 14 is slidably connected to the slide rail 12 through the slider 13. When the rotary shaft 18 drives the gear 19 to rotate, the gear 19 can drive the connecting rod 20 to drive the discharge door 21 to rotate through meshing with the rack 14. And the rack 14 is slidably connected to the slide rail 12 through the slider 13. The slider 13 and the slide rail 12 enable the rack 14 to move linearly.

[0027] Further, one end of the oil cylinder 10 is rotatably connected to the oil cylinder base 9 through a rotating pin, and the other end of the oil cylinder 10 is rotatably connected to the rack 14 through a rotating pin, which is convenient for when the oil cylinder 10 drives the rack 14 to move, so that the two ends of the oil cylinder 10 will not interfere with the rack 14 and the oil cylinder base 9.

[0028] Further, the rotating shaft contact 7 is installed on the end face of the rotary shaft 18 and is fixedly connected to the rotary shaft 18. The proximity switch 6 is installed inside the proximity switch mounting clip 5 through a bolt assembly. The rotary shaft 18 can drive the rotating shaft contact 7 to rotate. When the rotating shaft contact 7 triggers the proximity switch 6, the rotary shaft 18 stops rotating at this time, and the rotary shaft 18 can stop the discharge door 21 from rotating through the connecting rod 20. Therefore, the limit control of the discharge door 21 when it reaches the open or closed position can be realized.

[0029] Further, the storage tank 1 and the arc plate 2 form a complete storage mechanism. The reinforcing rib 16 is provided with a groove adapted to the discharge door 21. When it is necessary to open the discharge opening 3 below the storage tank 1, by rotating the discharge door 21 by 180 degrees, the discharge door 21 is located in the groove at this time, so as to realize the large-angle opening and closing of the discharge door 21.

[0030] During use, the oil cylinder 10 can drive the rack 14 to move, as shown in the attached Figure 2 and the attached Figure 3As shown, when it is necessary to unload the materials inside the storage tank 1, the oil cylinder 10 is started to drive the toothed rod 14 to move leftward. During this process, the slider 13 can be guided and limited by the slide rail 12. The slider 13 can move linearly on the slide rail 12, that is, the toothed rods 14 on both sides can move linearly synchronously. When the toothed rod 14 moves, it can drive the gear 19 to rotate clockwise through meshing with the gear 19. Furthermore, the gear 19 can drive the rotating shaft 18 to rotate clockwise, and the rotating shaft 18 can drive the discharge door 21 to rotate clockwise through the connecting rod 20. The limit control of the switch-in-place of the discharge door 21 is realized through the rotating shaft contact point 7 on the end face of the rotating shaft 18, so that the discharge door 21 stops rotating after rotating 180 degrees. At this time, the discharge door 21 is located in the groove on the reinforcing rib 16, thereby realizing the large-angle opening and closing of the discharge door 21 to improve the unloading efficiency.

[0031] Although the embodiments of the present invention have been shown and described, for those of ordinary skill in the art, it can be understood that various changes, modifications, substitutions and variations can be made to these embodiments without departing from the principle and spirit of the present invention. The scope of the present invention is defined by the appended claims and their equivalents.
