[0019] The following will be combined with the drawings in the embodiments of the utility model to clearly and completely describe the technical solutions in the embodiments of the utility model. Obviously, the described embodiments are only part of the embodiments of the utility model, not all of the embodiments. Based on the embodiments in the utility model, all other embodiments obtained by ordinary technicians in this field without creative work are within the scope of protection of the utility model.
[0020] See also Figure 1 - Figure 4 The utility model provides a technical solution: a hulling machine for new rice processing, comprising a shell 1, a feed port 2 and a screen frame 5. The feed port 2 is arranged at the top center of the shell 1. The feed port 2 is made of stainless steel and has a smooth surface, which is convenient for the new rice to enter the hulling machine. The bottom end of the feed port 2 is connected with a dispersion wheel 3 through a bearing 4. When working, in the process of rice falling, the dispersion wheel 3 will be driven to rotate by gravity. At this time, the rotation of the dispersion wheel 3 can make the rice on the dispersion wheel 3 disperse and fall, reducing the phenomenon of new rice accumulation on the screen frame 5.
[0021] After passing through the dispersion wheel 3, the new rice falls into the screen frame 5 connected to the upper side of the shell 1. The upper sides of the screen frame 5 are respectively connected with rubber blocks 8 by bolts. The other side of the rubber block 8 away from the screen frame 5 is connected with a spring 7. The screen frame 5 is connected to the inner surface of the shell 1 through the spring 7 and the rubber block 8 to prevent the high-frequency vibration of the machine during operation from reducing the service life of the machine. The rubber block 8 is used to gradually absorb the vibration. The diagonal ends of the screen frame 5 are fixed with vibration motors 9 through support plates 11. The two ends of the central axis of the vibration motor 9 are respectively connected with polarization blocks 10. Through the different weights and settings of the polarization blocks 10, the two groups of vibration motors drive the screen frame 5 to generate vibrations in two directions, horizontal and vertical, so as to hull the new rice in a way of simulating manual hulling. Three groups of sieve plates 6 are evenly arranged inside the sieve frame 5. The new rice falls into the next layer through the holes in the sieve plate 6 during the vibration process. The holes of the sieve plate 6 are slightly larger than the size of rice after hulling. After passing through the three groups of sieve plates 6 in sequence, the new rice will continue to pass through the funnel structure at the bottom of the sieve frame 5 into the lower stable frame 12.
[0022] The stabilizing frame 12 is fixed to the inside of the shell 1 by a long-handled screw 23. The long-handled screw 23 cooperates with the stabilizing frame 12 to prevent the falling new rice from destroying the stability of the frame. A screen 17 is arranged at the inner center of the stabilizing frame 12. The center of the screen 17 is connected with a rotating shaft 24. The transmission shaft 13 is used to connect the cross rotating rod 14 to the top of the screen 17. The top of the cross rotating rod 14 is connected with the transmission shaft 13. The other end of the transmission shaft 13 is connected to the motor 15. The cross rotating rod 14 can be driven to rotate only when the motor 15 is turned on. Rubber swing plates 16 are respectively arranged on the four rod bodies of the cross rotating rod. The rubber swing plates are made of soft materials. When rotating, the rice on the screen is repeatedly ground without destroying the integrity of the rice grains. At the same time, the rice grains can be prevented from piling up on the screen during rotation, thereby accelerating the passage of the rice grains.
[0023] The bottom of the stabilizing frame 12 is also a funnel structure to prevent the rice passing through the screen 17 from scattering elsewhere. A fan 18 is arranged on one side of the funnel outlet, and the air inlet of the fan 18 is connected with the air inlet 19 on the outer shell 1, and the air outlet of the fan 18 corresponds to the air outlet 20 on the outer shell 1, and the air flow blown out by the fan 18 can flow out through the air outlet 20, so as to form an air circulation channel at the bottom of the stabilizing frame 12. The light shell and debris of the rice falling into the channel will be carried away by the wind, and the whole rice will fall into the storage box 21 arranged below because of its own gravity, so that the staff can take out the rice conveniently, and the shell, debris and other materials blown away by the fan 18 will fall into the sundry material box 22 arranged next to the storage box 21, and can also be taken out for secondary utilization, so as to ensure the integrity of the product and properly use the sundry materials.
[0024] Working principle: When using a shelling machine for processing new rice, pour the new rice into the feed port 2, and the new rice falls into the screen frame 5 in an orderly manner through the rotation of the dispersion wheel 3. The two diagonal ends of the screen frame 5 are respectively provided with vibration motors 9. At this time, start the vibration motor 9, and through the different parameter settings of the polarization blocks 10 connected to the two ends of the vibration motor 9, the vibration motor 9 can synchronously drive the screen frame 5 to start vibrating in the vertical and horizontal directions, so that the new rice passes through the three groups of sieve plates 6 arranged in the screen frame 5, so that the vibration in two directions can simulate the fineness of manual shelling, so as to protect the integrity of the rice grains while shelling more efficiently, and fall into the funnel-shaped structure at the bottom of the screen frame 5, and then enter the lower stabilizing frame 12 from the outlet. A screen 17 is connected to the inner center of the stabilizing frame 12, and the center of the screen 17 is connected to the cross rotating rod 14 through the rotating shaft 24. The cross rotating rod 14 passes through the upper The transmission shaft 13 is connected to a motor 15. After the motor 15 is powered, the cross rotating rod 14 rotates, driving the rubber swing plate 16 installed on the rod body to rotate, pushing the new rice that has fallen on the screen 17 inside the stabilizing frame 12 to be crushed through the screen 17. The rubber swing plate 16 is a soft material that can gently crush the rice grains to prevent the integrity of the rice grains from being damaged. After the re-milling is completed, the rice grains pass through the screen 17 and enter the air duct blown out by the fan 18. The air duct combines the aerodynamic force and the gravity effect to screen the fallen rice grains. The shells, debris and other materials therein are lighter and will be carried out by the wind and blown to the air outlet 20 on the shell 1. The heavier new rice will fall directly into the storage box 21 arranged below under the action of gravity, waiting for the staff to take it out. The shells, debris and other impurities brought out by the fan will also fall into the miscellaneous material box 22 arranged next to the storage box 21, and the miscellaneous materials therein will be reused.
