[0025] The grain after being stirred and cleaned by the stirring component 1 enters the screening component 2 through the discharge port at the bottom, and the grain on the screening component 2 is screened and dehydrated by the power component 3 on the screening component 2, and the sorting is completed through the sorting port at the front end of the screening component 2.
[0026] See also Figure 2 The stirring assembly 1 includes a stirring mechanism 11 , and a stirring bracket 12 is fixedly connected to the outer surface of the stirring mechanism 11 .
[0027] See also Figure 2 The stirring bracket 12 includes a stirring base 123, four stirring pillars 121 are evenly fixedly connected to the outer side of the top of the stirring base 123, and stirring fixed columns 122 are fixedly connected to the upper and middle parts of the stirring pillars 121 on one side facing the center of the stirring base 123. The ends of the upper four stirring fixed columns 122 away from the stirring pillars 121 are fixedly connected to the outer surface of the stirring connecting column 111, and the ends of the middle four stirring fixed columns 122 away from the stirring pillars 121 are movably connected to the middle part of the outer surface of the fulcrum ball 116. A stirring barrel 124 is fixedly connected to the middle part of the top of the stirring base 123, and a discharge port is opened in the middle part of the bottom of the stirring base 123.
[0028] The stirring chassis 123 serves as the base of the entire assembly and fixes the stirring connecting column 111 and the fulcrum ball 116 for stirring. The stirring fixing column 122 supports 126, allowing the entire stirring mechanism 11 to rotate around the fulcrum ball 116 to achieve sufficient stirring. The stirring barrel 124 is a place for stirring and cleaning.
[0029] See also Figure 2 and Figure 3 The stirring mechanism 11 includes a stirring connecting column 111, the bottom end of the stirring connecting column 111 is fixedly connected to an origin gear 112, the bottom end of the origin gear 112 is rotatably connected to a rotating support plate 114, a driving motor is provided at the top of the rotating support plate 114, an end of the rotating support plate 114 away from the surrounding gear 113 passes through and is rotatably connected to a stirring rod 115, an end of the stirring rod 115 close to the rotating support plate 114 is fixedly connected to the surrounding gear 113, a fulcrum ball 116 is fixedly connected to the middle part of the outer surface of the stirring rod 115, an end of the stirring rod 115 away from the surrounding gear 113 is fixedly connected to a stirring head 117, and three stirring claws 118 are evenly fixedly connected to the outer surface of the stirring head 117.
[0030] Through the driving motor at the top of the origin gear 112, the rotating support plate 114 drives the stirring rod 115 to rotate around the origin gear 112, so that the stirring head 117 and the stirring claw 118 can stir in the stirring barrel 124, and the fulcrum ball 116 can keep the stirring of the stirring claw 118 always in the barrel to prevent it from shifting during the stirring process and also fix its stirring trajectory.

The angle of forty-five degrees allows the rotating support plate 114 to rotate in the barrel with only one fulcrum, and the mechanism is more stable. The orbiting gear 113 is meshed with the origin gear 112 at forty-five degrees. The angle of the orbiting gear 113 can apply rotation to itself through the meshing origin gear 112 during the rotation of the rotating support plate 114, thereby increasing the rotation while maintaining the revolution, which can make the stirring more thorough.
[0032] See also Figure 4The screening component 2 includes a left screening plate 21, a right screening plate 23 is arranged at a parallel position below the left screening plate 21, two supporting assembly columns 25 are movably connected on both sides of the left screening plate 21, and the middle parts of the rear ends of the two rear supporting assembly columns 25 are fixedly connected with the assembly base 24, the top ends of the rear supporting assembly columns 25 are fixedly connected with the mechanism support plate 22, and the top ends of the mechanism support plates 22 are fixedly connected to the bottom end of the stirring chassis 123, the rear end of the left screening plate 21 is fixedly connected to the upper part of the front end of the pushing plate 35, and the rear end of the right screening plate 23 is fixedly connected to the middle part of the front end of the pushing plate 35, and the front ends of the left screening plate 21 and the right screening plate 23 are both provided with discharge ports, the discharge port of the left screening plate 21 is biased to the left, and the discharge port of the right screening plate 23 is biased to the right, and the screen gap of the left screening plate 21 is larger than that of the right screening plate 23.
[0033] The grain will fall onto the left screening plate 21 through the discharge port, and then move forward quickly due to the thrust applied by the power component 3. The left screening plate 21 will be pulled back by the power component 3, and the grain on the left screening plate 21 will continue to move forward due to inertia, and then repeat this process. During the forward movement of the grain, smaller grains will fall into the right screening plate 23 through the gap on the left screening plate 21, so that grains of different specifications can be distinguished, and the water droplets after cleaning can also be shaken off during the shaking process.
[0034] See also Figure 4 The supporting combination column 25 includes a supporting column 251, and the middle and upper parts of the supporting column 251 close to the left screening plate 21 are fixedly connected with a connecting rod 252.

[0036] See also Figure 5The power assembly 3 includes a power wheel 31, a driving motor is provided at the bottom end of the power wheel 31, and a rotating pillar 32 is fixedly connected to the outer side of the power wheel 31. The rotating pillar 32 is pushed forward by the rotation of the power wheel 31, and a transmission column 33 is rotatably connected to the top of the rotating pillar 32. The propulsion fluid of the rotating pillar 32 drives the transmission column 33 to be pushed forward. A movable groove is provided at the end of the transmission column 33 away from the rotating pillar 32, and a connecting block 34 is rotatably connected in the movable groove. The connecting block 34 pushes the pushing plate 35 under the action of the transmission column 33, and a pushing plate 35 is fixedly connected to the end of the connecting block 34 away from the transmission column 33. The pushing fluid of the pushing plate 35 will push the front left screening plate 21 and the right screening plate 23, and the entire power assembly 3 can achieve a shaking effect between pushing and pulling.
[0037] Working principle:
[0038] First, with the discharge port closed, pour the grain and water that need to be cleaned into the mixing barrel 124, then start the motor on the stirring mechanism 11, and use the motor to drive the rotating support plate 114 to fully stir the entire stirring barrel 124. After the stirring is completed, open the discharge port to allow the grain and water to fall onto the left screening plate 21, and the water will flow out through the gap between the left screening plate 21 and the right screening plate 23. Then open the power component 3. Under the push and pull action of the power component 3, the left screening plate 21 and the right screening plate 23 are pushed and pulled synchronously and quickly, and the larger grain particles on the left screening plate 21 will be retained and moved forward, and the smaller grain particles will fall into the right screening plate 23 through the gap on the left screening plate 21. The screening process is carried out in this way, and the separated grains will be output from different places through the discharge ports of their respective screening plates for concentration.
