[0031] 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.

[0035] Specifically, when using the device, after the rice seeds in the salt water container 1 are screened, they can fall onto the filter screen 202 through the discharge pipe 203. At this time, the spray pipe 205 is started to clean them. At the same time, the motor 206 drives the first rotating rod 207 to rotate, and the first rotating rod 207 further drives the flat gears 208 on both sides to rotate synchronously. Since the half gear 210 and the flat gear 208 are meshed with each other, the half gear 210 will also rotate accordingly. As the half gear 210 rotates, the knocking rod 211 will be driven to knock the filter screen 202, which can effectively cause the rice seeds accumulated on the filter screen 202 to move to the left along the inclined filter screen 202, and finally fall out of the device through the discharge port 16. After the screening process is completed, it can be automatically rinsed to ensure the continuous and efficient operation of the equipment. At this time, the water pump 215 is started to transport the cleaning water collected in the lower hopper 214 to the water tank 212, so as to complete the recovery of the cleaning water and reduce the workload of the staff.

[0036] Reference Figure 1 and Figure 2 The top right side of the salt storage box 4 is connected with a salt adding port 15, and the top of the salt adding port 15 is threadedly connected with a salt adding cover 14, and sodium chloride can be added to the salt storage box 4 through the salt adding port 15. The top rear side of the water tank 212 is connected with a water adding port 17, and the top of the water adding port 17 is threadedly connected with a water adding cover 18, and water can be added to the water tank 212 through the water adding port 17;

[0037] Specifically, the salt adding cover 14 is opened, and sodium chloride can be added into the salt storage box 4 through the salt adding port 15 , and the water adding cover 18 is opened, and water can be added into the water tank 212 through the water adding port 17 .

[0038] Reference Figure 1 The bottom of the salt water container 1 is fixedly connected with a support frame 19, and the four corners of the bottom of the support frame 19 are fixedly connected with walking wheels 20, which can facilitate the staff to move the device. The upper and middle part of the front side of the salt water container 1 is fixedly connected with a control panel 21, and the control panel 21 is electrically connected with the motor 7 and the motor 206 respectively, and the operation of the motor 7 and the motor 206 can be controlled through the control panel 21;

[0039] Specifically, the staff can conveniently move the device through the walking wheels 20, and the control panel 21 can control the operation of the motor 7 and the motor 206 respectively. The model of the motor 7 is F130 micro, and the model of the motor 206 is MS8012.

[0040] Working principle: When the salt water concentration changes during the process of using the device to screen seeds, the motor 7 is started, and the motor 7 starts to drive the worm 8 to rotate. Since the worm wheel 10 and the worm 8 are meshed with each other, when the worm 8 rotates, the worm wheel 10 will drive the transmission rod 9 to rotate. The transmission rod 9 will then drive the front valve 11 to rotate. When the valve 11 opens downward, the water in the storage box 3 can enter the salt water container 1 through the water outlet 5. When the valve 11 opens upward, the sodium chloride in the salt storage box 4 can enter the salt water container 1 through the first salt outlet hole 6 and the second salt outlet hole 22. By rotating the valve 11, the concentration of the salt water in the salt water container 1 can be dynamically controlled;

[0041] And when using the device, after the rice seeds in the salt water container 1 are screened, they can fall onto the filter screen 202 through the discharge pipe 203. At this time, the spray pipe 205 is started to clean them. At the same time, the motor 206 will drive the first rotating rod 207 to rotate, and the first rotating rod 207 will drive the flat gears 208 on both sides to rotate. Since the half gear 210 and the flat gear 208 are meshed with each other, the half gear 210 will drive the knocking rod 211 to knock the filter screen 202, so that the rice seeds above the filter screen 202 can move to the left along the inclined filter screen 202, and finally fall out of the device through the discharge port 16. After the rice seeds are screened, they can be automatically cleaned. At this time, the water pump 215 is started to transport the cleaning water collected in the lower hopper 214 to the water tank 212 to complete the recovery of the cleaning water.
