The output end of the first motor 14 extends to the inside of the first unloading funnel 4 and is fixedly connected to the first rotating plate 6. The output end of the first motor 14 is fixedly connected to the first pulley 15. One end of the second rotating plate 7 extends to the outside of the second unloading funnel 5 and is fixedly connected There is a second pulley 16, and the first pulley 15 is connected to the second pulley 16 through a first transmission belt 17. The transmission assembly includes a transmission shaft 18 and a linkage unit. The transmission shaft 18 is rotatably connected to both sides of the interior of the base 1, and the conveyor belt 8 is driven by the transmission shaft 18. One end of the transmission shaft 18 extends to the outside of the base 1 and is fixedly connected to a worm gear 19. The outer side of the base 1 is rotatably connected to a worm gear 20 through a fixed block. The worm gear 20 is meshed with the worm gear 19.

[0023] Through the above technical solution, the first rotating plate 6 is initially in a closed state, and the second rotating plate 7 is initially in an open state. First, the second motor 21 is started by an external controller, and the output end of the second motor 21 drives the worm 20 to rotate, and the worm 20 then drives the worm wheel 19 to rotate through the meshing relationship, and the worm wheel 19 then drives the conveyor belt 8 through the transmission shaft 18, so that multiple groups of packaging bags or packaging boxes are continuously transported through the conveyor belt 8. At the same time, the worm 20 can drive the third pulley 22 to rotate, so that the third pulley 22 drives the fourth pulley 23 to rotate through the second transmission belt 24, and the fourth pulley 23 can be The feeding conveyor belt 10 is driven by the driving shaft inside the feeding conveyor belt 10, so that the corn seeds are continuously transported by the feeding conveyor belt 10, and the corn seeds are transported to the inside of the second feeding funnel 5, and fall into the inside of the first feeding funnel 4 through the feeding port at the bottom of the second feeding funnel 5, and are pressed downward toward the inside of the support seat 3 through the first feeding funnel 4 and the sliding rod 13, and the pressure sensor 11 is squeezed by the spring 12. When the weight of the corn seeds accumulates to a preset value, the pressure sensor 11 can detect it and transmit the signal to the external controller, which starts the first motor 14 and The second motor 21 is turned off, so that the first motor 14 drives the first rotating plate 6 and the first pulley 15 to rotate, and the first pulley 15 then drives the second pulley 16 and the second rotating plate 7 to rotate through the first transmission belt 17, so that the corn seeds can be discharged through the discharge port at the bottom of the first discharge funnel 4. At the same time, after the second motor 21 is turned off, the conveyor belt 8 and the feeding conveyor belt 10 stop running, and the discharged corn seeds can be packaged through the packaging bag on the top of the conveyor belt 8. After the packaging bag stays long enough, all the fallen corn seeds are packaged, and then the first motor 14 and the second motor 21 are turned off again.

The external controller can facilitate the staff to quickly control the first motor 14 and the second motor 21.

[0026] When in use, the first rotating plate 6 is initially in a closed state, and the second rotating plate 7 is initially in an open state. First, the second motor 21 is started by an external controller, and the output end of the second motor 21 drives the worm 20 to rotate, and the worm 20 then drives the worm wheel 19 to rotate through the meshing relationship, and the worm wheel 19 then drives the conveyor belt 8 through the transmission shaft 18, so that multiple groups of packaging bags or packaging boxes are continuously transported through the conveyor belt 8.

The first transmission belt 17 drives the second pulley 16 and the second rotating plate 7 to rotate, and the corn seeds can be discharged through the discharge port at the bottom of the first discharge funnel 4. At the same time, after the second motor 21 is turned off, the conveyor belt 8 and the feeding conveyor belt 10 stop running, and the discharged corn seeds can be packaged through the packaging bag on the top of the conveyor belt 8. After the packaging bag stays long enough, all the fallen corn seeds are packaged. Then the first motor 14 and the second motor 21 are started again and the first rotating plate 6 is driven to close again through the above working principle, and the second rotating plate 7 is opened again. At the same time, the conveyor belt 8 and the feeding conveyor belt 10 are opened again. The corn seeds can be packed in this reciprocating manner. The device can sense the weight of the corn seeds inside the first feeding funnel 4 through the pressure sensor 11, and discharge them when the appropriate weight is reached, and carry out quantitative packaging with the packaging bag, thereby avoiding the situation that the corn seeds are not discharged enough when a temporary blockage occurs due to the regular feeding and packaging of the corn seeds, thereby improving the accuracy of the quantitative packaging of the corn seeds. The baffle 25 can be set to block the corn seeds transported on the feeding conveyor belt 10 to prevent them from slipping due to the inclined surface of the feeding conveyor belt 10. The external controller can facilitate the staff to quickly control the first motor 14 and the second motor 21.
