When the screen frames 21 on both sides of the elastic connecting plate 22 move toward each other, the abutment rubbers are squeezed. When the screen frames 21 on both sides of the elastic connecting plate 22 move toward each other, the abutment rubbers are reset, and the abutment rubbers always remain in abutment with the screen frames 21.

[0041] A second electric slider is fixedly connected to the bottom of the vertical baffle 30 , and the second electric slider is slidably connected to the top wall plate of the rectangular groove. The second electric slider drives the vertical baffle 30 to move to achieve the clamping of the cabin door 3 .

[0042] As a further implementation scheme of the present invention, a built-in cylinder 32 is opened inside the moving block 15, and an output water pipe 14 is slidably connected inside the built-in cylinder 32. The water outlet hole 25 is connected to the built-in cylinder 32, and the connection point between the two is located at the top center of the built-in cylinder 32.

The water outlet end of the piston water pump 11 is connected to the output water pipe 14. A transmission rod 8 is provided on one side of the piston water pump 11. The transmission rod 8 is used to drive the piston water pump 11 to pump water, and the transmission rod 8 passes through the side wall of the screen cabin 1, and the transmission rod 8 is connected to an external driving device.

[0043] In the specific implementation, the external driving device is a prior art, which can be realized by adding a motor and an eccentric wheel on the outside. This technology is a prior art and will not be disclosed in detail here.

[0044] When the transmission rod 8 moves toward the inside of the screen cabin 1 , the drainage efficiency of the water outlet hole 25 is lower than the water supply efficiency of the output water pipe 14 .

[0045] As a further implementation scheme of the present invention, a strip groove is opened on one side of the screen cabin 1, and the strip groove is located at the lowest end of the triangular partition 10. The outer side of the strip groove is fixedly connected with a dust outlet 6, and the tops of both sides of the dust outlet 6 are fixedly connected with vertical plates, which are movably abutted against the dust reduction component.

[0046] In a specific implementation, the vertical plate is movably abutted against the dust reduction assembly through the extension plates arranged at both ends of the protrusion 4.

[0047] As a further implementation scheme of the present invention, both sides of the end of the moving block 15 away from the output water pipe 14 are fixedly connected with sliding rods 35, and abutment springs 27 are sleeved on the sliding rods 35.

The two ends of the abutment spring 27 are respectively fixedly connected to the support plate 18 and the moving block 15. The end of the sliding rod 35 away from the moving block 15 is fixedly connected to the driving plate 28, and the two sliding rods 35 are respectively fixedly connected to the two ends of one side of the driving plate 28.

[0048] In a specific implementation, the abutment spring 27 is used to drive the moving block 15 to reset, thereby enabling the guide plate 17 to perform horizontal reciprocating motion.

[0049] As a further embodiment of the present invention, the dust reduction assembly includes a piston cylinder 26 and a hollow groove 31. The piston cylinder 26 is fixedly connected to the end wall panel of the water tank 20 away from the piston water pump 11. The piston cylinder 26 is used to extract water from the water tank 20 and supply it to the hollow groove 31. The bottom of the hollow groove 31 is connected to a plurality of atomizing nozzles, and the atomizing nozzles are located above the outlet 6. The interior of the piston cylinder 26 is slidably connected to a piston plate, and a piston rod 33 is fixedly connected to the center of one side of the piston plate close to the drive plate 28. The end of the piston rod 33 away from the piston plate passes through the end wall panel of the piston cylinder 26 and is fixedly connected to the drive plate 28.

[0050] In a specific implementation, the piston rod 33 is slidably connected to the end wall of the piston cylinder 26 away from the outlet 6, and a vent hole is opened on the piston cylinder 26 for maintaining the internal air pressure balance. The vent hole is opened on the piston cylinder 26 and is located at one end of the piston cylinder 26 close to the driving plate 28.

[0051] As a further implementation scheme of the present invention, a one-way liquid inlet pipe 12 is opened in the wall panel at one end of the screen cabin 1, and the two ends of the one-way liquid inlet pipe 12 are respectively connected to the water tank 20 and the piston cylinder 26, and the connection point between the one-way liquid inlet pipe 12 and the piston cylinder 26 is located at the end of the piston cylinder 26 away from the driving plate 28. The end of the piston cylinder 26 away from the driving plate 28 is also connected to a one-way liquid outlet pipe 34, and the end of the one-way liquid outlet pipe 34 away from the piston cylinder 26 is connected to a connecting hose 5, and the end of the connecting hose 5 away from the one-way liquid outlet pipe 34 is connected to the hollow groove 31.

[0052] In a specific implementation, during the process of opening the hatch 3 , the connecting hose 5 will move along with the movement of the protrusion 4 , and the connecting hose 5 will be located on the sides of the sieve cabin 1 and the protrusion 4 .

[0054] In a specific implementation, the hatch 3 can be effectively supported by the arrangement of the extension plate and the vertical plate. At the same time, the arrangement of the extension plate can also help prevent the connecting hose 5 from being squeezed between the vertical plate and the extension plate and damaged, thereby providing a certain degree of protection for the connecting hose 5. The bottom of the rectangular groove is also provided with a chamfer, which abuts against the rib between the flange 7 and the protrusion 4 on the hatch 3.

[0055] Working principle of the present invention:

[0056] When the present invention is in use, the grains are first put into the sieve cabin 1 through the feed hopper 2. After the grains are put into the sieve cabin 1, the connection between the feed hopper 2 and the sieve cabin 1 is effectively blocked by controlling the horizontal baffle 29, which is helpful to avoid dust overflowing through the connection between the feed hopper 2 and the sieve cabin 1 during the grain screening process.

[0057] After the connection between the feed hopper 2 and the screen cabin 1 is blocked, the external driving device is turned on and the piston water pump 11 is driven by the driving device to work. During the operation of the piston water pump 11, the external driving device drives the transmission rod 8 to reciprocate. When the transmission rod 8 moves toward the outside of the piston water pump 11, the water in the water tank 20 is drawn into the piston water pump 11. When the transmission rod 8 moves toward the inside of the piston water pump 11, the water in the piston water pump 11 is squeezed into the output water pipe 14, and then enters the built-in cylinder 32 through the output water pipe 14.

[0058] After the water flows into the built-in cylinder 32, since the amount of water output by the piston water pump 11 is greater than the amount of water discharged by the water outlet 25, the water pressure in the built-in cylinder 32 will be used to push the moving block 15 to slide in the direction away from the piston water pump 11. During this process, part of the water that has entered the moving block 15 will also be discharged through the water outlet 25. During the process of the piston water pump 11 drawing water from the water tank 20, the piston water pump 11 suspends the water supply to the output water pipe 14. Therefore, under the elastic force of the abutment spring 27, the water in the output water pipe 14 and the built-in cylinder 32 will be squeezed out, and the moving block 15 will be prompted to move in the direction close to the output water pipe 14. During the operation of the piston water pump 11, under the action of the output water pipe 14 and the abutment spring 27, the moving block 15 can also be prompted to perform horizontal reciprocating motion.

[0059] During the horizontal reciprocating motion, the moving block 15 will drive the lateral sliders 19 on both sides to move. During the movement of the lateral sliders 19, the guide plates 17 will be driven to move. During the reciprocating motion, the guide plates 17 will always contact the guide wheels 24, thereby driving the guide wheels 24 to drive the limit column 23 to move up and down. During the lifting and lowering of the limit column 23, the elastic connecting plate 22 will be driven to move up and down, thereby driving the screen frame 21 to shake, and the grains placed in the screen cabin 1 will be screened, so that the grains are retained on the screen frame 21, and the impurities in the grains are screened onto the triangular partition 10. During the shaking of the screen frame 21, when the screen frame 21 descends, the elastic connecting plate 22 located between two adjacent screen frames 21 will be squeezed to a certain extent, thereby enabling the screen frame 21 to shake effectively.

[0060] In the process of the piston water pump 11 supplying water to the output water pipe 14, after the water is discharged through the water outlet 25, due to the high water pressure in the output water pipe 14 and the built-in cylinder 32, the kinetic energy contained in the water discharged through the water outlet 25 is also high. After leaving the water outlet 25, the water will impact on the bottom wall plate of the triangular partition 10. By utilizing the impact of the water flow, the water flow will cause the triangular partition 10 to vibrate to a certain extent after impacting the bottom of the triangular partition 10. The vibration can be used to shake off the impurities screened on the triangular partition 10, so that the impurities can be discharged through the impurity outlet 6.

[0061] During the reciprocating motion of the moving block 15, the moving block 15 will also drive the driving plate 28 to move through the sliding rod 35. After the driving plate 28 moves, it will drive the piston rod 33 to move. During the movement of the piston rod 33 in the direction close to the driving plate 28, water will be pumped from the water tank 20 through the one-way liquid inlet pipe 12, and the water will be temporarily stored in the piston cylinder 26. In the process of the piston rod 33 moving in the direction away from the driving plate 28, the water in the piston cylinder 26 will be squeezed into the one-way liquid outlet pipe 34. After entering the one-way liquid outlet pipe 34, the water will enter the connecting hose 5, and finally enter the hollow groove 31 through the connecting hose 5, and finally sprayed on the miscellaneous outlet 6 through the atomizing nozzle connected to the bottom of the hollow groove 31, so as to effectively reduce dust at the miscellaneous outlet 6.

[0062] After the screening work is completed, the external driving device is turned off, and then the hatch 3 is opened to take out the grains in the screening cabin 1. In the process of opening the hatch 3, the flange 7 at the end of the hatch 3 will abut against the end of the screen frame 21 closest to the hatch 3 to fix the hatch 3. After the hatch 3 is opened, the extension plates on both sides of the protrusion 4 will also abut against the vertical plates on both sides of the outlet 6 to support the hatch 3. The support of the hatch 3 by the flange 7 and the extension plate can effectively improve the stability of the hatch 3, and together support the hatch 3 during the discharge process.

[0063] By setting the water trough 20, on the one hand, the weight of the sieve cabin 1 can be effectively increased, which is beneficial to avoid the displacement of the sieve cabin 1 due to excessive vibration during the screening of grains, and the stability of the sieve cabin 1 is increased by increasing the weight. On the other hand, by increasing the weight of the sieve cabin 1, water can be effectively supplied to the hollow groove 31 to reduce dust from the device, which is beneficial to avoid a large amount of dust in the surrounding environment during the screening of grains. Secondly, the water flow is guided to the triangular partition 10 through the water outlet 25, so that the water flow impacts the triangular partition 10, which can also help to prompt the triangular partition 10 to shake the dust into the outlet 6 to avoid dust from being trapped on the triangular partition 10.

[0064] Through the setting of the piston water pump 11, on the one hand, it can drive the transverse slider 19 to drive the guide plate 17 to perform reciprocating motion, and then drive the screen 9 to shake, so as to effectively screen the grains. On the other hand, it can also drive the piston cylinder 26 to effectively supply water to the hollow groove 31 through the abutment spring 27, so as to drive the atomizing nozzle at the bottom of the hollow groove 31 to effectively reduce dust at the dust outlet 6. Through the setting of the hatch 3 and the horizontal baffle 29, the sealing of the screen cabin 1 can be effectively achieved, so that during the process of screening grains, only the dust outlet 6 of the screen cabin 1 is in contact with the outside world.
