After husking, the rice needs to be screened and filtered, and the screening process of the existing rice screening and filtering mechanism is relatively simple.

Excessive accumulation of impurities affects the rice filtering effect. At the same time, the impurities accumulated inside cannot be completely separated from the rice when discharged uniformly, and need to be manually processed later, increasing labor costs.

[0003] Therefore, it is necessary to develop an automatic rice impurity filtering device that can completely separate impurities from rice through filtering. Utility Model Content

DETAILED DESCRIPTION

[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. Example

[0020] An automatic rice impurity filtering device, such as Figure 1 , Figure 3 and Figure 4 As shown, it includes a bottom plate 1, a fixing frame 2, a shell 5, a first filter screen 7, a funnel 6, a slide plate 13, a second baffle plate 14, a collecting box 15 and a filtering mechanism. The bottom plate 1 is connected to the left side with the fixing frame 2, the fixing frame 2 is slidably connected to the right side with the slide plate 12, the right side of the slide plate 12 is fixedly connected to the shell 5, the upper side of the shell 5 is connected to the funnel 6, the funnel 6 is used to prevent rice from falling, the upper side of the shell 5 is connected to the first filter screen 7, the lower part of the shell 5 is connected to the slide plate 13, the front and rear sides of the right part of the slide plate 13 are fixedly connected to the second baffle plate 14, the right side of the bottom plate 1 is connected to the collecting box 15, the collecting box 15 is located on the lower right side of the slide plate 13, and the middle part of the shell 5 is provided with a filtering mechanism for completely separating impurities such as stones from rice.

[0021] like Figure 1 , Figure 3 and Figure 4 As shown, the filtering mechanism includes a second filter screen 701, a third filter screen 702 and a collecting frame 8. The collecting frame 8 is connected to the middle part of the right side of the shell 5, and the collecting frame 8 is also connected to the lower left side of the shell 5. The two collecting frames 8 are used to collect filtered impurities. The second filter screen 701 is fixedly connected to the middle part of the shell 5, and the second filter screen 701 is higher on the left and lower on the right. The third filter screen 702 is fixedly connected to the lower side of the shell 5, and the third filter screen 702 is lower on the left and higher on the right. A discharge port is opened in the middle part of the right side of the shell 5, and a discharge port is also opened on the lower left side of the shell 5. Both discharge ports are used to discharge impurities.

[0022] When the rice needs to be filtered, the rice is poured into the upper part of the shell 5. The funnel 6 on the upper side of the shell 5 can prevent the rice from falling when it is poured in. The first filter screen 7 filters out large impurities such as rice stalks mixed in the rice. When there are too many impurities such as rice stalks on the first filter screen 7, people can directly take out the impurities for cleaning. The rice and other impurities such as stones filtered out by the first filter screen 7 fall on the second filter screen 701. Since the second filter screen 701 is higher on the left and lower on the right, the larger stone impurities roll to the right into the right collection frame 8. The filtered rice and other smaller impurities fall onto the third filter screen 702. Since the third filter screen 702 is lower on the left and higher on the right, the remaining impurities filtered roll to the left into the collection frame 8 on the left. The rice falls onto the slide plate 13, so that the rice is filtered out from the slide plate 13. 3 slides down into the collection box 15, and the second baffles 14 on both sides can block the rice to prevent the rice from falling from the side. When the rice in the collection box 15 reaches a certain amount, pull the handle 16 to pull the collection box 15 to the rear side. The handle 16 is made of rubber and has an anti-slip effect. The collection box 15 moves a short distance to the right, and people can collect the rice in the collection box 15. After collection, the collection box 15 is pushed to the left to reset. After the filtration is completed, the impurities such as stones in the two collection frames 8 are uniformly collected. Through the three filtrations of the rice, the filtered impurities can be completely separated from the rice, and the filtered impurities are prevented from being mixed with rice, thereby avoiding manual secondary filtration. The operation is simple, time-saving and labor-saving, and the filtration effect is better. Example

[0023] On the basis of Example 1, Figure 1-Figure 4 As shown, a vibration mechanism for vibrating the shell 5 is also included, and the vibration mechanism includes a motor 3, a pulley group 4, a first baffle 401, a push plate 402, a pressure rod 9, a guide rod 10 and a spring 11. The front left side of the fixed frame 2 is fixedly connected to the motor 3, and the upper side of the fixed frame 2 is rotatably connected to the pulley group 4. The output shaft of the motor 3 rotates to drive the pulley group 4 to rotate. A plurality of push plates 402 are connected to the belt of the pulley group 4. The front and rear sides of the fixed frame 2 are fixedly connected to the first baffle 401. The bottom of the shell 5 is slidably connected to the guide rod 10, and the bottom of the guide rod 10 is fixedly connected to the bottom plate 1. A spring 11 is connected between the bottom of the shell 5 and the bottom plate 1, and the spring 11 is sleeved on the guide rod 10. The left side of the top of the shell 5 is fixedly connected to the pressure rod 9.

[0024] In order to prevent people from lifting the rice and pouring it into the shell 5, which consumes too much physical strength, people can start the motor 3, the output shaft of the motor 3 rotates, driving the pulley group 4 to rotate, thereby driving the push plate 402 to rotate, and people can pour the rice directly onto the belt. The push plate 402 on the belt can drive the rice to move upward, so that the rice falls into the funnel 6, thereby filtering the rice. Since the material of the shell 5 is plastic, the shell 5 is relatively light, and the push plate 402 rotates to squeeze the pressure rod 9 downward, and the pressure rod 9 moves downward to drive the shell 5 to move downward, and drives the slider 12 to slide downward. The fixed frame 2 guides the slider 12, and the spring 11 is compressed. When the push plate 402 rotates to separate from the pressure rod 9, the spring 11 recovers its deformation and drives the shell 5 and the slider 12 to move upward, so that the push plate 402 intermittently squeezes the pressure rod 9, so that the shell 5 is intermittently vibrated, thereby driving the first filter screen 7, the second filter screen 701 and the third filter screen 702 inside to vibrate, thereby accelerating the filtering speed, making the filtering effect better, and avoiding filter clogging.

[0025] The above is only a specific implementation of the utility model, but the protection scope of the utility model is not limited thereto. Any technician familiar with the technical field can easily think of changes or substitutions within the technical scope disclosed by the utility model, which should be included in the protection scope of the utility model. Therefore, the protection scope of the utility model should be based on the protection scope of the claims.
