[0022] Specifically, the storage box flipping mechanism 7 includes a storage box 72, a rotating shaft 73, a large gear 74, a small gear 75, a second motor 76, a mounting seat 77, and a moving component 78. A moving component 78 is provided at the lower end inside the discharge box 1. The upper end of the moving component 78 is provided with a mounting seat 77. A second motor 76 is provided on the side of the mounting seat 77. The output end of the second motor 76 is provided with a small gear 75. A large gear 74 is meshed and installed on the side of the small gear 75. A rotating shaft 73 is provided on the side of the large gear 74. The other end of the rotating shaft 73 is provided with a storage box 72.

[0023] By adopting the above technical solution, when it is necessary to pour the mulberry leaves in the storage box 72 into the silkworm trays, the moving component 78 drives the storage box 72 to move to the outside of the discharge box 1. At this time, the second motor 76 is turned on. The second motor 76 drives the small gear 75 to rotate through the output end. The rotation of the small gear 75 drives the large gear 74 to rotate. The rotation of the large gear 74 drives the rotating shaft 73 to rotate. The rotation of the rotating shaft 73 drives the storage box 72 to flip, so as to pour the internal mulberry leaves into the silkworm trays.

[0024] Specifically, a support block 71 is provided on one side of the upper end of the mounting seat 77, and a notch corresponding to the storage box 72 is opened on the other side of the upper end of the mounting seat 77.

[0025] By adopting the above technical solution, the setting of the support block 71 can ensure that the storage box 72 is in a horizontal state when reset. A notch corresponding to the storage box 72 is opened on the other side of the upper end of the mounting seat 77, which can enable the storage box 72 to rotate more than ninety degrees, so as to smoothly pour out the mulberry leaves.

[0026] Specifically, the moving component 78 includes a connecting slider 781, a screw 782, and a third motor 783. A third motor 783 is provided at the lower end inside the discharge box 1. The output end of the third motor 783 is provided with a screw 782. A connecting slider 781 is threadedly connected to the surface of the screw 782. The connecting slider 781 and the side of the mounting seat 77 are fixedly connected by bolts.

[0027] By adopting the above technical solution, the third motor 783 is turned on. The third motor 783 drives the screw 782 to rotate through the output end. The rotation of the screw 782 drives the connecting slider 781 to slide, so as to drive the mounting seat 77 to slide outward.

[0028] When this embodiment is in use, when it is necessary to pour the mulberry leaves in the storage box 72 into the silkworm tray, turn on the third motor 783. The third motor 783 drives the screw 782 to rotate through the output end. The rotation of the screw 782 drives the connecting slider 781 to slide, so as to drive the mounting seat 77 to slide outward. The sliding of the mounting seat 77 drives the storage box 72 to move to the outside of the discharge box 1. At this time, turn on the second motor 76. The second motor 76 drives the small gear 75 to rotate through the output end. The rotation of the small gear 75 drives the large gear 74 to rotate. The rotation of the large gear 74 drives the rotating shaft 73 to rotate. The rotation of the rotating shaft 73 drives the storage box 72 to turn over, so as to pour the internal mulberry leaves into the silkworm tray. The setting of the support block 71 can ensure that the storage box 72 is in a horizontal state when reset. A notch corresponding to the storage box 72 is opened on the other side of the upper end of the mounting seat 77, so that the storage box 72 can rotate more than 90 degrees, so as to smoothly pour out the mulberry leaves.

[0029] Embodiment 2

[0030] The difference between this embodiment and Embodiment 1 is that the accurate discharge control mechanism 8 includes a pressing plate 81, a PLC controller 82 and a gravity sensor 83. A gravity sensor 83 is arranged inside the storage box 72. A pressing plate 81 is arranged at the upper end of the gravity sensor 83. A PLC controller 82 is arranged outside the discharge box 1.

[0031] By adopting the above technical solution, the value of the gravity sensor 83 is set through the PLC controller 82. At this time, when the mulberry leaves falling into the storage box 72 exceed the set amount, the gravity sensor 83 converts the monitored signal into an electrical signal and transmits it to the PLC controller 82. The PLC controller 82 controls the first motor 11 to turn off, so that the mulberry leaves no longer fall. At the same time, it controls the third motor 783 to start. Until the storage box 72 is moved out of the outside of the discharge box 1, then the PLC controller 82 controls the second motor 76 to open, so as to control the storage box 72 to turn over and discharge.

[0032] Specifically, the PLC controller 82, the gravity sensor 83, the first motor 11, the second motor 76 and the third motor 783 are all electrically connected through wires.

[0033] By adopting the above technical solution, the setting of this structure can ensure the operation of the device.

[0034] In use, the numerical value of the gravity sensor 83 is set by the PLC controller 82. When the mulberry leaves falling into the storage bin 72 exceed the set amount, the gravity sensor 83 converts the monitored signal into an electrical signal and transmits it to the PLC controller 82. The PLC controller 82 controls the first motor 11 to turn off, so that the mulberry leaves no longer fall. At the same time, it controls the third motor 783 to start. Until the storage bin 72 is moved out of the outer side of the discharge bin 1, the second motor 76 is controlled by the PLC controller 82 to open, so as to control the storage bin 72 to turn over and discharge materials.

[0035] The PLC controller 82 in the present utility model is a publicly known technology, and the selected model is Siemens S7-300.

[0036] The gravity sensor 83 in the present utility model is a publicly known technology, and the selected model is the 897X series of AMK.

[0037] The working principle and usage process of the present utility model: When in use, when it is necessary to pour the mulberry leaves in the storage bin 72 into the silkworm tray, the third motor 783 is turned on. The third motor 783 drives the screw 782 to rotate through the output end. The rotation of the screw 782 drives the connecting slider 781 to slide, so as to drive the mounting seat 77 to slide outward. The sliding of the mounting seat 77 drives the storage bin 72 to move to the outer side of the discharge bin 1. At this time, the second motor 76 is turned on again. The second motor 76 drives the small gear 75 to rotate through the output end. The rotation of the small gear 75 drives the large gear 74 to rotate. The rotation of the large gear 74 drives the rotating shaft 73 to rotate. The rotation of the rotating shaft 73 drives the storage bin 72 to turn over, so as to pour the internal mulberry leaves into the silkworm tray. The setting of the support block 71 can ensure that the storage bin 72 can be in a horizontal state when reset. A notch corresponding to the storage bin 72 is opened on the other side of the upper end of the mounting seat 77, so that the storage bin 72 can rotate more than 90 degrees, so as to smoothly pour out the mulberry leaves; The numerical value of the gravity sensor 83 is set by the PLC controller 82. When the mulberry leaves falling into the storage bin 72 exceed the set amount, the gravity sensor 83 converts the monitored signal into an electrical signal and transmits it to the PLC controller 82. The PLC controller 82 controls the first motor 11 to turn off, so that the mulberry leaves no longer fall. At the same time, it controls the third motor 783 to start. Until the storage bin 72 is moved out of the outer side of the discharge bin 1, the second motor 76 is controlled by the PLC controller 82 to open, so as to control the storage bin 72 to turn over and discharge materials.
