[0020] The following will be combined with the drawings in the embodiments of the present invention to clearly and completely describe the technical solutions in the embodiments of the present invention. Obviously, the embodiments described are only part of the embodiments of the present invention, not all of the embodiments. Based on the embodiments of the present invention, all other embodiments obtained by ordinary technical personnel in this field without making creative efforts shall fall within the scope of protection of the present invention.

[0021] See also Figures 1 to 4The utility model provides a technical solution: a rice slag removal device for agricultural production, comprising a feed hopper 1, the bottom end of the feed hopper 1 vertically penetrates the middle of the top of a slag removal box 2, a wind box 3 is provided on one side outer wall of the slag removal box 2, and a slag collecting mechanism 4 is provided on the other side outer wall of the slag removal box 2. A filter screen plate 5 is provided inside the slag removal box 2, and a shielding mechanism 6 is rotatably connected to the left and right inner walls of the slag removal box 2 directly below the filter screen plate 5. A collecting hopper 7 is provided at the bottom of the slag removal box 2, and a discharge channel 8 is provided at the bottom end of the collecting hopper 7, and the bottom end of the discharge channel 8 vertically penetrates the middle of the top of the collecting box 9.

[0022] In this embodiment, Figure 2 and Figure 3 As shown, a fan 301 is screwed to the inner wall of the wind box 3 away from the slag removal box 2, and an isolation net 302 is embedded in the fan 301 on the side close to the slag removal box 2; it should be noted that the operator can first pour the rice from the feed hopper 1 into the interior of the slag removal box 2, so that it falls to the top of the filter screen plate 5, and at the same time, the operator can simultaneously start the vibration motor 501 and the fan 301, so that the filter screen plate 5 vibrates the rice placed on the top of it, and the fan 301 can generate an airflow through the isolation net 302 through the rotation of its fan blades, and blow toward the filter screen plate 5, thereby blowing the light dust and impurities mixed in the rice to the slag collecting mechanism 4 provided on the other side, until the rice is completely removed. All the dust and impurities are blown into the slag collecting mechanism 4. In actual use, the fan 301 generates a strong airflow through high-speed rotation, which can quickly separate the light dust and impurities from the rice and blow them to the slag collecting mechanism 4, thereby improving the slag removal efficiency and preventing the light dust from forming a thin covering layer on the surface of the filter screen plate 5, which would hinder the passage of materials. At the same time, it can avoid the light dust from being adsorbed on the surface of large-particle impurities, increasing their volume and weight, and further aggravating the blockage of the sieve holes of the filter screen plate 5. During the slag removal process, the isolation net 302 can effectively block the impurity particles from entering the interior of the bellows 3, avoiding their impact on the normal operation of the fan 301.

[0023] In this embodiment, Figure 2 and Figure 3As shown, a filter screen 401 is embedded on the side of the slag collecting mechanism 4 close to the slag removal box 2, and a slag discharge channel 402 is provided on the side of the slag collecting mechanism 4 away from the slag removal box 2. A slag collecting box 403 is provided at the bottom of the slag discharge channel 402, and the bottom wall of the slag discharge channel 402 is an inclined surface; it should be noted that when the operator starts the fan 301 to blow the light dust and impurities in the rice placed on the top of the filter screen plate 5 to the slag collecting mechanism 4, the dust and impurities will first pass through the filter screen 401, and then enter the slag discharge channel 402, and fall to the bottom wall of the slag discharge channel 402 under the action of gravity. At the same time, the dust and impurities will flow along the slag discharge channel The inclined bottom wall 402 slides directly into the slag collecting box 403 located just below it and is collected. In actual use, the filter screen 401 can filter out the dust and impurities blown to the slag collecting mechanism 4, thereby effectively separating the impurities from the rice and improving the slag removal efficiency. The slag discharge channel 402 can guide the filtered dust and impurities into the slag collecting box 403, wherein its inclined bottom wall can make the dust and impurities slide more smoothly, avoiding clogging the slag discharge channel 402 and affecting the normal operation of the equipment, thereby improving the collection efficiency. The slag collecting box 403 can conveniently clean the dust and impurities collected inside it.

[0024] In this embodiment, Figure 3 As shown, the mesh diameter of the isolation net 302 is smaller than the mesh diameter of the filter net 401; it should be noted that the operator can start the fan 301 to blow the light dust and impurities in the rice toward the slag collecting mechanism 4. During this period, the fine mesh of the isolation net 302 can effectively isolate the flying dust and impurities, preventing them from entering the interior of the bellows 3, while the filter net 401 can allow the dust and impurities to directly pass through its mesh and enter the interior of the slag discharge channel 402. The isolation net 302 and the filter net 401 play different roles through meshes of different apertures. In actual use, the mesh of the isolation net 302 is finer, which can effectively block the flying dust particles and prevent them from entering the interior of the bellows 3 with the airflow, thereby ensuring that the fan 301 will not be damaged due to the inhalation of too much dust, reducing the possibility of malfunction, and also ensuring the cleanliness of the interior of the bellows 3. The mesh of the filter net 401 is larger, so that the blown light impurities can pass through it smoothly, which helps to collect the impurities and ensure the smooth operation of the preliminary slag removal operation.

[0025] In this embodiment, Figure 4As shown, the shielding mechanism 6 includes a driving motor 601, a moving screw 602, a sliding rod 603, a slider 604, a baffle 605 and a screw block 606. The left and right ends of the moving screw 602 are rotatably connected to the left and right inner walls of the slag removal box 2. The driving motor 601 is plugged into one end of the moving screw 602, the sliding rod 603 is plugged into the left and right inner walls of the slag removal box 2, the screw block 606 is screwed to the outer wall of the moving screw 602, the slider 604 is slidably connected to the outer wall of the sliding rod 603, and the slider 604 and the screw block 606 are connected. A baffle 605 is provided; it should be noted that, after the operator starts the fan 301 to blow the light dust and impurities in the paddy to the inside of the slag collecting mechanism 4 to complete the preliminary filtration, the operator can start the vibration motor 501 and the drive motor 601 again, and the movable screw 602 plugged in with the bottom end of the drive motor 601 starts to rotate, and drives the screw block 606 screwed thereto to start moving horizontally. At the same time, the baffle 605 connected to the screw block 606 and the slider 604 located on the other side of the baffle 605 will be driven to fit the slider. The rod 603 moves horizontally synchronously, during which the baffle 605 will fit the bottom of the filter screen plate 5, changing the sieve hole area it blocks, thereby changing the size of the sieve hole, which is convenient for screening and filtering impurities and residues of various sizes inside the rice. After the residue filtering is completed, the drive motor 601 is started again to drive the baffle 605 to move horizontally until the sieve hole is completely opened, so that the rice can fall out of it. In actual use, the driving motor 601 drives the moving screw 602 to rotate, thereby causing the screw block 606 and the baffle 605 to move horizontally, so that the operator can filter the impurities and residues according to the actual situation. According to actual needs, the area of ​​the sieve holes blocked by the baffle 605 can be flexibly changed, thereby realizing automatic adjustment of the sieve hole size, and then being able to grade and filter impurities of different sizes, thereby improving the filtering effect, and at the same time greatly improving the degree of automation of the equipment, reducing manual intervention, and improving work efficiency. After completing the residue filtration, the shielding mechanism 6 can also drive the baffle 605 to completely open the sieve holes, so that the rice can fall smoothly from the sieve holes, avoiding the occurrence of blockage, thereby ensuring smooth material flow and helping to improve the overall work efficiency of the equipment.

[0026] In this embodiment, Figure 4As shown, vibration motors 501 are screwed on the left and right sides of the top of the filter screen plate 5; it should be noted that, after the operator starts the fan 301 to blow the light dust and impurities in the rice into the interior of the slag collecting mechanism 4 to complete the preliminary filtration, the operator can start the vibration motors 501 screwed on the left and right sides of the top of the filter screen plate 5 again to generate a vibration frequency and drive the entire filter screen plate 5 screwed thereto to vibrate, so that the rice on the top of the filter screen plate 5 is driven to shake around. During this period, the impurities and slag mixed in the rice will be directly shaken when they are vibrated to the sieve holes. In actual use, the vibration motor 501 generates vibrations to drive the rice on the top of the filter screen plate 5 to shake around, so that the impurity particles mixed in the rice can be more easily vibrated to the sieve holes and pass through them, thereby speeding up the separation speed of impurities and rice. This vibration method can also more thoroughly separate impurities from rice, improving the quality of screening. At the same time, the vibration screening provided by the vibration motor 501 can adapt to rice with different humidity and viscosity, ensuring effective screening under various conditions.

[0027] In this embodiment, Figure 1 and Figure 3 As shown, the left and right sides of the collecting box 9 are internally slidably connected to the collecting box 901; it should be noted that when the operator starts the filter screen plate 5 screwed to the bottom end of the vibration motor 501 and starts vibrating, the impurities and residues mixed in the rice are shaken off from the sieve holes. At this time, the impurities and residues will fall downward into the collecting hopper 7 under the action of gravity, and slide along the inner wall of the collecting hopper 7 into the discharge channel 8. At the same time, the operator can open the solenoid valve to allow the impurities and residues inside to continue to fall downward into the collecting box 9 plugged in therewith and be collected in the collecting box 901. Then the operator can manually slide and pull out the collecting box 901 to clean the residue inside it, and then start the shielding valve again. The blocking mechanism 6 allows the baffle 605 to fully open the sieve holes, allowing the rice to fall through and eventually fall into the collection box 901 after cleaning, completing the rice collection. In actual use, the collection box 901 can conveniently collect the impurities and residues that fall from the discharge channel 8, which is convenient for subsequent cleaning and processing. When the collection box 901 is full of residues, the operator can manually pull it out of the collection box 9 for cleaning. The operation is simple and convenient, reducing cleaning time and labor intensity, and is easy to repair and replace. At the same time, the cleaned collection box 901 can also collect rice again, realizing the complete separation and collection of impurities from rice, avoiding impurities from being re-mixed into rice during the subsequent collection process, and improving the quality of rice.

[0028] The use method and advantages of the utility model: The rice slag removal equipment used in agricultural production, when in use, works as follows:

[0029] like Figure 1 、 Figure 2 、 Figure 3 and Figure 4 As shown, first, the operator can pour the rice from the feed hopper 1 into the interior of the slag removal box 2, so that it falls to the top of the filter screen plate 5. At the same time, the operator can simultaneously start the vibration motor 501 and the fan 301, so that the filter screen plate 5 vibrates the rice placed on the top thereof. During this period, the fan 301 can generate an airflow through the isolation net 302 through the rotation of its fan blades and blow it toward the filter screen plate 5, thereby blowing the light dust and impurities mixed in the rice to the slag collecting mechanism 4 provided on the other side. At the same time, When the dust and impurities are filtered, they will first pass through the filter screen 401 and then enter the slag discharge channel 402, and fall to the bottom wall of the slag discharge channel 402 under the action of gravity. At the same time, the dust and impurities will slide directly along the inclined bottom wall of the slag discharge channel 402 to the slag collecting box 403 located just below it and be collected. After completing the preliminary filtration, the operator can start the vibration motor 501 and the drive motor 601 again, and the moving screw 602 connected to the bottom end of the drive motor 601 starts to rotate, and drives the The screw block 606 screwed to it starts to move horizontally. At the same time, the baffle 605 connected to the screw block 606 and the slider 604 on the other side of the baffle 605 will be driven to move horizontally in synchronization with the slide bar 603. During this period, the baffle 605 will fit the bottom of the filter screen plate 5, changing the screen hole area it blocks, thereby changing the size of the screen hole, making it easier to screen and filter impurities and residues of various sizes inside the rice. The impurities and residues will fall down into the collecting hopper 7 under the action of gravity and follow the The inner wall of the collecting hopper 7 slides down into the discharge channel 8. At the same time, the operator can open the solenoid valve to allow the impurities and residues inside it to continue to fall down into the collecting box 9 connected to it and be collected in the collecting box 901. Then the operator can manually slide out the collecting box 901 to clean the residue inside it, and then start the shielding mechanism 6 to make the baffle 605 fully open the sieve hole, so that the rice falls from it and finally falls into the cleaned collecting box 901, completing the rice collection.
