[0021] The technical solution of this patent is further described in detail below in conjunction with specific implementation methods.

[0022] like Figure 1-5 As shown, the utility model provides a technical solution: a rice quantitative filling and vacuuming equipment, comprising a vacuum chamber 1, a control panel 2 is installed on the vacuum chamber 1, a vacuum pump 3 is installed on one side of the vacuum chamber 1, an anti-sliding block 4 is connected to the bottom of the vacuum chamber 1, a connecting plate 5 is connected to the top of the vacuum chamber 1, connecting grooves 27 are opened on the inner walls on both sides of the connecting plate 5, and rubber pads 28 are connected in the connecting grooves 27, the vacuum chamber 1 is slidably connected to a cover 6 through the connecting plate 5, connecting strips 29 are connected on both sides of the cover 6, a handle 30 is connected to the cover 6, the connecting strip 29 is slidably connected to the connecting groove 27, and the sliding of the connecting strip 29 in the connecting groove 27 enables the staff to quickly complete the positioning and installation of the cover 6, and when the connecting strip 29 enters the connecting groove 27, it squeezes the rubber pad 28, so that the rubber pad 28 is deformed and fits with the connecting strip 29, thereby sealing the gap.

[0023] A pressure sensing scale 7 is installed in the vacuum bin 1, a support frame 8 is connected above the vacuum bin 1, a storage hopper 9 is installed on the support frame 8, a transport pipe 10 is connected to the support frame 8, a feed pipe 11 is connected above the transport pipe 10, a discharge pipe 12 is connected below the transport pipe 10, a first mounting plate 13 is connected to one side of the transport pipe 10, a first motor 14 is installed on the first mounting plate 13, a rotating rod 15 is connected to the output shaft of the first motor 14, a transport blade 16 is connected to the rotating rod 15, the transport pipe 10 is connected to the storage hopper 9 through the feed pipe 11, the rotating rod 15 is rotatably connected in the transport pipe 10, the transport blade 16 is a spiral design, the spiral transport blade 16 will flip the rice at the same time when transporting rice, thereby ensuring that the rice is loose in the transport pipe 10, and preventing the rice from blocking the transport pipe 10 and affecting the unloading.

[0024] A quantitative box 17 is installed on the pressure sensing scale 7, and fixed plates 19 are connected on both sides of the quantitative box 17. A second mounting plate 20 is connected to the fixed plate 19 on one side of the quantitative box 17, and a second motor 21 is installed on the second mounting plate 20. A threaded rod 22 is connected to the output shaft of the second motor 21. A guide rod 26 is connected to the fixed plate 19 on the side of the quantitative box 17 away from the threaded rod 22. Both ends of the threaded rod 22 are provided with threads and the thread directions are opposite. The side of the moving plate 23 away from the threaded rod 22 is slidably connected to the guide rod 26. When the moving plate 23 moves along the threaded rod 22, the guide rod 26 can guide and limit the movement of the moving plate 23 to avoid the moving plate 23 from tilting during movement, thereby improving the stability of the movement of the moving plate 23.

[0025] A movable plate 23 is threadedly connected to the threaded rod 22, and a hot melt plate 24 is connected to the movable plate 23. A heating plate 18 is installed on one side of the quantitative box 17, and a heat conductive wire 25 is connected to the heating plate 18. The heating plate 18 is connected to the hot melt plate 24 through the heat conductive wire 25. When the two movable plates 23 push the packaging bag to close, the heating plate 18 will increase the temperature of the hot melt plate 24 through the heat conductive wire 25, so that the hot melt plate 24 melts the packaging bag, thereby bonding and sealing the packaging bag to prevent air from entering and affecting packaging storage.

[0026] The working principle of the utility model is:

[0027] The rice in the storage hopper 9 enters the transport pipe 10 from the feed pipe 11, and then the first motor 14 is started to rotate the rotating rod 15, so that the transport blade 16 pushes the rice in the transport pipe 10 to the discharge pipe 12, so that the rice can flow out of the discharge pipe 12 evenly to avoid the rice blocking the transport pipe 10. The rice flowing out of the discharge pipe 12 will fall into the packaging bag in the quantitative box 17. Since the capacity of the quantitative box 17 is limited, and as the rice continues to increase, the pressure sensor scale 7 will transmit the weight change, thereby controlling the rotation of the first motor 14 to prevent excessive outflow of rice, and then the connecting strip 29 is connected. Push it into the connecting groove 27 to fix the sealing cover 6 on the vacuum chamber 1. When the connecting strip 29 enters the connecting groove 27, it will squeeze the rubber pad 28, causing the rubber pad 28 to deform and fit the connecting strip 29, thereby sealing the gap. The second motor 21 is started to rotate the threaded rod 22, so that the two movable plates 23 move toward each other along the threaded rod 22, thereby pushing the packaging bag to close. At the same time, the vacuum pump 3 is started to extract the air in the vacuum chamber 1. After the packaging bag is closed, the heating plate 18 will heat the hot melt plate 24 through the heat conducting wire 25, so that the hot melt plate 24 melts the packaging bag, thereby sticking and sealing the packaging bag to prevent air from entering.
