The outer wall of the arc plate 12 is fitted with the inner cavity side wall of the shell 10, and the inner cavity side wall of the shell 10 is provided with a storage groove 18. An opening and closing mechanism for separating the arc plate 12 from the storage groove 18 is provided between the upper parts of the symmetrical mounting plates 11. When the driving mechanism drives the shell 10 to rotate, the storage groove 18 is driven to approach the position of the opening and closing mechanism. After the position of the storage groove 18 coincides with the position of the opening and closing mechanism, the two sides of the opening and closing mechanism rotate downward.

[0036] See also Figure 2-3The lower part of the side of the mounting plate 11 away from the driving mechanism is fixedly connected to the base 1, and the upper part of the side of the mounting plate 11 away from the driving mechanism is fixedly connected with a feed pipe 4, and the lower end of the feed pipe 4 is communicated with the inner cavity of the mounting plate 11, and the beans to be dried can be put into the inner cavity of the mounting plate 11 through the feed pipe 4. The drying mechanism includes a hot air blower 2 (the hot air blower is an industrial hot air blower commonly used in the prior art, and its composition includes three major parts: a blower, a heater and a control circuit, which can realize the regulation of working temperature and air volume), the hot air blower 2 is fixedly connected to the upper end of the base 1 near the feed pipe 4, and the side of the hot air blower 2 near the feed pipe 4 is fixedly connected with a ventilation pipe 3, and a plurality of ventilation holes are opened on the side wall of the mounting plate 11, and the hot air is transmitted to the inner cavity of the mounting plate 11 through the ventilation pipe 3 and the ventilation holes by the hot air blower 2, thereby drying the beans in the inner cavity of the mounting plate 11.

[0037] See also Figure 1 and Figure 6The driving mechanism includes a driving motor 5 and a servo motor 6. The bottoms of the driving motor 5 and the servo motor 6 are fixedly connected to the end of the base 1 away from the hot air blower 2, wherein the output end of the driving motor 5 is fixedly connected to an incomplete gear 8, and the end of the incomplete gear 8 close to the servo motor 6 is provided with a driven gear 9, and the incomplete gear 8 and the driven gear 9 are meshed with each other. The outer wall of the shell 10 is fixedly connected to a sleeve shell 7 on the side close to the driving motor 5, and the middle side wall of the sleeve shell 7 close to the servo motor 6 is fixedly connected to the driven gear 9, that is, when the driving motor 5 drives the incomplete gear 8 to rotate, the sleeve shell 7 will be driven to rotate synchronously through the driven gear 9. The housing 10 is driven to rotate synchronously, that is, when the incomplete gear 8 rotates one circle, it will drive the driven gear 9 to rotate 180°, thereby driving the storage tank 18 to rotate 180°. After the driven gear 9 rotates 180°, the teeth of the incomplete gear 8 are separated from the teeth of the driven gear 9, so that the housing 10 remains stationary after rotating 180°. The middle part of the symmetrical mounting plate 11 rotates together with a screw rod 13, and the end of the screw rod 13 away from the hot air blower 2 is transmission-connected to the servo motor 6, that is, the output end of the servo motor 6 passes through the driven gear 9 and the side wall of the casing 7 and is fixedly connected to the screw rod 13, and the outer wall of the screw rod 13 is threadedly connected with a push rod. The upper parts of the plates 14 and the symmetrical mounting plates 11 are fixedly connected with a balance bar 15, and the outer wall of the balance bar 15 is slidably connected to the upper part of the push plate 14, that is, when the screw 13 is driven to rotate by the servo motor 6, the push plate 14 will be driven to reciprocate horizontally, thereby pushing the beans in the horizontal direction, so that gaps are generated between the beans, which makes it easier for hot air to contact the surface of the beans, thereby improving the drying efficiency of the beans. A support platform is arranged below the base 1, and the lower end of the base 1 is rotatably connected to the inner cavity side wall of the mounting platform near the side of the hot air blower 2, and the lower end of the base 1 is connected to the inner cavity bottom of the support platform between the middle part of the side away from the hot air blower 2. The base 1 is dynamically connected to the mounting plate 11 and is driven by the electric push rod to rotate, so that the beans put into the inner cavity of the mounting plate 11 are evenly laid in the inner cavity of the mounting plate 11 under the pushing action of the push plate 14 and the inclination of the base 1, so as to facilitate the hot air to dry the beans, and a discharge port is provided at the lower part of one end of the mounting plate 11 close to the feed pipe 4. After the beans are dried, the discharge port is opened and the base 1 is tilted by pushing the push plate 14 and lifting the electric push rod to move the beans toward the discharge port, so that the dried beans in the inner cavity of the mounting plate 11 are pushed out from the discharge port, thereby completing the unloading of the beans.

[0038] See also Figure 4The opening and closing mechanism includes a fixing plate 19, both ends of which are fixedly connected to the side walls of the symmetrical mounting plate 11, and a symmetrical baffle 17 is arranged at the lower end of the mounting plate 11, and one end of the symmetrical baffle 17 close to the middle of the lower end of the fixing plate 19 is rotatably connected to the mounting plate 11, and a support plate 16 is arranged below the baffle 17, and the support plate 16 is vertically slidably connected to the symmetrical mounting plate 11, that is, when the support plate 16 moves vertically downward, the symmetrical baffle 17 will automatically deflect downward due to gravity, and when the support plate 16 moves vertically upward, the support plate 16 will push the symmetrical baffle 17 to move vertically upward. The baffle 17 returns to its initial position, thereby blocking the gap between the upper ends of the symmetrical arc plates 12. When the storage trough 18 drives the beans to rotate synchronously with the shell 10, before the center position of the storage trough 18 coincides with the center position of the fixing plate 19, the baffle 17 will continue to block the gap between the arc plates 12, thereby preventing the beans from escaping from the inner cavity of the storage trough 18 too early when they are in the inner cavity of the storage trough 18, thereby causing the beans to fall to one side of the inner cavity of the mounting plate 11, causing more beans to accumulate on one side, which is not conducive to the overall drying of the beans.

[0039] See also Figure 5 , a driven block 24 is fixedly connected to the middle of both ends of the support plate 16, a moving groove 20 is opened in the middle of one side of the mounting plate 11 close to the arc plate 12, the moving groove 20 is located above the mounting plate 11, and the lower end surface of the feed pipe 4 is lower than the plane where the bottom of the inner cavity of the moving groove 20 is located, the outer wall of the driven block 24 is vertically slidably connected to the inner cavity of the moving groove 20, a driving plate 22 is arranged below the driven block 24, the driving plate 22 is vertically slidably connected in the moving groove 20, and a symmetrical elastic key 23 is fixedly connected between the driving plate 22 and the driven block 24, the lower end of the driving plate 22 is elastically connected to the bottom of the inner cavity of the moving groove 20 through a spring, a groove 28 is opened on the upper part of one side of the mounting plate 11 close to the arc plate 12, and a mounting block 25 is slidably connected to the inner cavity of the groove 28, and a movable block 26 is fitted on one side of the mounting block 25, and the side wall of the movable block 26 is vertically slidably connected to the mounting block 25 The middle part of the lower end of the mounting block 25 is fixedly connected with a traction rope 21, and the end of the traction rope 21 away from the mounting block 25 penetrates into the moving groove 20 from the bottom of the inner cavity of the groove 28 close to the side of the moving groove 20, and passes through the driven block 24 and is fixedly connected with the middle part of the upper end of the driving plate 22. That is, when the mounting block 25 moves in the inner cavity of the groove 28, the mounting block 25 will drive the traction rope 21 to move synchronously, and pull the driving plate 22, the elastic key 23 and the driven block 24 to move vertically upward in the inner cavity of the moving groove 20 through the traction rope 21. When the upper end surface of the driven block 24 is in contact with the top of the inner cavity of the moving groove 20, the driven block 24 cannot continue to move upward in the inner cavity of the moving groove 20. If the mounting block 25 continues to drive the traction rope 21 to move, the driving plate 22 will continue to approach the position of the driven block 24, and the elastic key 23 will bend to adapt to the upward movement of the driving plate 22.

[0040] See also Figure 9-10 When the mounting block 25 and the movable block 26 are located on the side of the inner cavity of the groove 28 close to the movable groove 20, the upper end surface of the movable block 26 is higher than the upper end surface of the mounting block 25.

The inner cavity of the groove 28 is provided with a guide groove 29 that slides with the guide rod 27. The guide groove 29 includes a balancing groove and an oblique groove. When the guide rod 27 is located in the inner cavity of the balancing groove, the position of the movable block 26 remains unchanged. When the guide rod 27 enters the inner cavity of the oblique groove from the inner cavity of the balancing groove, The upper end surface of the movable block 26 will continue to approach the upper end surface of the mounting block 25, that is, when the guide rod 27 moves with the movable block 26 to the connection between the balancing groove and the inclined groove, the driven block 24 will move vertically upward to the top of the inner cavity of the movable groove 20, and as the movable block 26 continues to move, that is, after the guide rod 27 enters the inner cavity of the inclined groove, the traction rope 21 continues to pull the driving plate 22 upward. Under the action of the pulling force of the traction rope 21, since the driven block 24 cannot continue to move upward, the elastic key 23 will bend toward the position of the traction rope 21, so that the driving plate 22 can continue to move upward with the traction rope 21 until the upper end surface of the movable block 26 coincides with the plane where the upper end surface of the mounting block 25 is located.

[0041] See also Fig.11 A second groove 32 is provided on the side of the inner cavity side wall of the shell 10 near the groove 28, and the position of the second groove 32 corresponds to the position of the groove 28.

After the beans in the inner cavity of the storage groove 18 fall back into the inner cavity of the mounting plate 11, as As the storage groove 18 continues to rotate, the driven plate 34 will push the movable block 26 and the mounting block 25 to move in the inner cavity of the groove 28 during the process of the driven plate 34 rotating with the storage groove 18, thereby driving the driven block 24 to move upward through the traction rope 21, and then driving the support plate 16 to move vertically upward, driving the symmetrical baffles 17 to rotate and block the gap on the upper part of the symmetrical arc plate 12 again. After the movable block 26 moves to the position of the inclined groove with the driven plate 34, the movable block 26 gradually approaches the position of the mounting block 25 and separates from the driven plate 34. The vertical distance between the two ends of the inclined groove is greater than the distance between the upper end surface of the movable block 26 and the upper end surface of the mounting block 25.

The connecting rod and the side wall of the inner cavity of the sliding groove are elastically connected by a spring. When the upper end of the driven block 24 fits between the top of the inner cavity of the movable groove 20, the limit block 3 5 is engaged in the card slot to fix the position of the driven block 24, and then fix the position of the support plate 16, so as to achieve the effect of fixing the position of the baffle 17. The side of the limit block 35 away from the moving block 30 is provided with a first inclined surface. In the process of the driven block 24 moving up, the side wall of the driven block 24 will contact with the first inclined surface, thereby pushing the limit block 35 to move toward the inner cavity of the slide slot, and after the top of the driven block 24 is attached to the top of the moving slot 20, the limit block 35 is horizontally moved toward the direction of the driven block 24 under the action of elastic force, until the limit block 35 is engaged in the inner cavity of the card slot, and the driven block 24 is limited and fixed.

At this time, under the action of elastic force, the driven block 24 is driven to move downward in the inner cavity of the movable groove 20 through the driving plate 22, so that the mounting block 25 and the movable block 26 are pulled toward the position of the movable groove 20 through the traction rope 21, so that the movable block 26 is fitted with the side wall of the driven plate 34.
