[0023] Such as Figure 2As shown in the figure, a seed screening device for rice cultivation includes a box body 1; a plurality of fixed columns 2 are fixedly connected to the inner wall of the box body 1; a filter box 3 is slidably connected to the outside of the fixed column 2; a plurality of telescopic springs 4 are fixedly connected to the side of the filter box 3; the other side of the telescopic spring 4 is fixedly connected to the box body 1; two fixing plates 5 are fixedly connected to one end of the filter box 3; a sliding column 6 is fixedly connected to the center position of the fixing plate 5; a driving motor 7 is fixedly connected to the outside of the box body 1; the output end of the driving motor 7 is fixedly connected to a first transmission rod 8; a first fixing screw 9 is rotatably connected to the inside of the first transmission rod 8; one end of the first fixing screw 9 is fixedly connected to a second transmission rod 10; a second fixing screw 11 is rotatably connected to the inside of the second transmission rod 10; one end of the second fixing screw 11 is rotatably connected to the sliding column 6; a first fixing block 12 is fixedly connected to the inner wall of the box body 1; the first fixing block 12 is slidably connected to the sliding column 6; during operation, when it is necessary to remove impurities mixed in the seeds, by starting the driving motor 7, the first transmission rod 8 is driven to rotate, and then through the transmission of the second transmission rod 10, the sliding column 6 can slide back and forth inside the first fixing block 12, thereby driving the filter box 3 to slide outside the fixed column 2. In this step, when it is necessary to remove impurities mixed in the seeds, through the back-and-forth sliding of the filter box 3, the seeds are dispersed on the filter box 3, improving the uniformity and efficiency of screening. At the same time, the seeds are screened through the filter holes at the bottom, and the mixed impurities can be left on the surface of the filter box 3, improving the purity of the seeds and reducing the failure of the seeder caused by impurities mixed in the seeds, thereby improving the seeding efficiency.

[0024] As Figure 3As shown, a support slide rail 13 is fixedly connected to the inner side of the bottom of the box body 1; a screening water tank 14 is slidably connected to the top of the support slide rail 13; a slide rail groove 15 is formed inside the screening water tank 14; a collection box 16 is placed inside the screening water tank 14; a first slide rail post 17 is fixed to one side of the collection box 16; the first slide rail post 17 slides inside the slide rail groove 15; a baffle placement cavity 19 is formed at the bottom of the collection box 16; a collection baffle 20 is placed inside the baffle placement cavity 19; a second slide rail post 18 is fixedly connected to one side of the collection baffle 20; the second slide rail post 18 slides inside the baffle placement cavity 19; a rotating screw 21 is fixedly connected to one side of the collection box 16; a retaining piece 22 is rotatably connected to one side of the rotating screw 21; during operation, when it is necessary to remove empty shells and underfilled seeds, water can be first injected into the screening water tank 14 to make the empty shells and underfilled seeds float. Then, by pushing the collection box 16 to slide inside the screening water tank 14, when the empty shells and underfilled seeds are collected into the collection box 16, the collection baffle 20 is then pulled out, and then the collection baffle 20 is rotated and erected inside the collection box 16, and then the retaining piece 22 is rotated to close the opening of the collection box 16. In this step, when it is necessary to remove empty shells and underfilled seeds, since the empty shells and underfilled seeds are relatively lighter in mass compared to normal seeds, the empty shells and underfilled seeds float, improving the overall quality of the seeds. Then, through the structural cooperation of the collection box 16 and the collection baffle 20, the empty shells and underfilled seeds are collected, removing the empty shells and underfilled seeds, reducing the workload of manual screening and collection, and lowering the labor cost.

[0025] As Figure 2 shown, a support block 23 is fixedly connected to the inner side of the box body 1; a sliding plate 24 is slidably connected to the top of the support block 23; during operation, when the device is in use, by pulling the sliding plate 24 to slide above the support block 23, the size of the channel through which the seeds enter the device is changed. In this step, under the action of the sliding plate 24, the flow rate of the seeds entering the device is controlled, enabling the device to operate in the optimal working state, improving the screening efficiency, reducing the wear and damage of parts caused by equipment overload, and extending the service life of the device.

[0026] As Figure 4 shown, a rotating column 25 is rotatably connected to the inner side of one side of the box body 1; a rotating block 26 is fixedly connected to the outer side of the rotating column 25; a rotating door 27 is fixedly connected to one side of the rotating block 26; during operation, when it is necessary to pull out the screening water tank 14 to collect the screened seeds, by pulling the rotating door 27 to rotate inside the box body 1 and then pulling out the screening water tank 14, it can be taken out. In this step, when it is necessary to pull out the screening water tank 14 to collect the screened seeds, through a simple pulling action, the operator can complete the collection of the seeds, improving the overall working efficiency.

[0027] As Figure 4 shown, a dust suction fan 28 is fixedly connected to the inside of one side of the box body 1; a fixing frame 29 is fixedly connected to the outside of the box body 1; a filter net 30 is fixedly connected to the inside of the fixing frame 29; during operation, by starting the dust suction fan 28 to generate suction, the dust generated inside the device is sucked in, and then the dust is guided to the fixing frame 29 and intercepted by the internal filter net 30. This step reduces the risk of dust inhalation by the staff through a simple filtration system, thereby protecting their health. At the same time, a clean working environment also helps to improve the work efficiency and comfort of the staff, further enhancing the overall work quality.

[0028] As Figure 1 shown, a second fixing block 31 is fixedly connected to one end of the box body 1; a protective shell 32 is rotatably connected to one side of the second fixing block 31; during operation, through the function of the protective shell 32, the transmission motor 7 inside is protected.

[0029] As Figure 1 shown, moving pulleys 33 are fixedly connected to the bottom end of the box body 1; during operation, when the device needs to be moved, by the rotation of the moving pulleys 33, the device is pushed to move. This step reduces the need for manual handling, thereby reducing the labor intensity and improving the work efficiency.

[0030] Working principle: During operation, when it is necessary to remove impurities mixed in the seeds, start the drive motor 7, which drives the first drive rod 8 to rotate. Then, through the transmission of the second drive rod 10, the sliding column 6 can slide back and forth inside the first fixed block 12, driving the filter box 3 to slide outside the fixed column 2. When it is necessary to remove impurities mixed in the seeds, through the back-and-forth sliding of the filter box 3, the seeds are dispersed on the filter box 3, improving the uniformity and efficiency of screening. At the same time, the seeds are screened through the filter holes at the bottom, and the mixed impurities can be left on the surface of the filter box 3, improving the purity of the seeds and reducing the failures of the seeder caused by impurities mixed in the seeds, thus improving the seeding efficiency. During operation, when it is necessary to remove empty and underdeveloped seeds, first inject water into the screening water tank 14 to make the empty and underdeveloped seeds float. Then, push the collection box 16 to slide inside the screening water tank 14. When the empty and underdeveloped seeds are collected in the collection box 16, pull out the collection baffle 20, and then make the collection baffle 20 rotate and stand up inside the collection box 16, and then rotate the baffle 22 to close the opening of the collection box 16. When it is necessary to remove empty and underdeveloped seeds, since the empty and underdeveloped seeds are lighter in mass compared to normal seeds, they float, improving the overall quality of the seeds. Then, through the structural cooperation of the collection box 16 and the collection baffle 20, the empty and underdeveloped seeds are collected, removing the empty and underdeveloped seeds, reducing the workload of manual screening and collection, and reducing the labor cost. During operation, when the equipment is in use, pull the sliding plate 24 to slide above the support block 23, thereby changing the size of the channel for the seeds to enter the equipment. Through the action of the sliding plate 24, the flow rate of the seeds entering the equipment is controlled, enabling the equipment to operate in the best working state, improving the screening efficiency, reducing the wear and damage of parts caused by equipment overload, and extending the service life of the equipment. During operation, when it is necessary to pull out the screening water tank 14 to collect the screened seeds, rotate the rotating door 27 to rotate inside the box body 1, and then pull out the screening water tank 14 to take it out. When it is necessary to pull out the screening water tank 14 to collect the screened seeds, through a simple pulling action, the operator can complete the collection of the seeds, improving the overall working efficiency. During operation, start the dust suction fan 28 to generate suction to suck the dust generated inside the equipment, and then the dust is guided to the fixed frame 29 and intercepted by the internal filter screen 30. Through this simple filtering system, the risk of dust inhalation by the staff is reduced, protecting their health. At the same time, a clean working environment also helps to improve the working efficiency and comfort of the staff, further enhancing the overall working quality. During operation, through the function of the protective shell 32, the drive motor 7 inside is protected. Through the function of the protective shell 32,It reduces the erosion and damage of external factors such as dust, dirt, and moisture to the drive motor 7, maintaining the cleanliness and stability of its internal environment. When the equipment needs to be moved during operation, the rotation of the moving pulley 33 is used to push the equipment to move. This step reduces the need for manual handling, thereby reducing the labor intensity and improving the work efficiency.
