[0003] A Chinese patent discloses a movable grain-rough separation screen, with the authorization announcement number CN218637872U. The patented technology sets universal wheels at the bottom of the bracket so that the entire device can be moved freely, which is convenient for personnel to use. In addition, semicircular rods are set on the screen, which can make the grain-rough mixture be simply lifted up when it comes into contact with it, so that the impurities in the grain-rough mixture can be sucked into the debris box with the help of the vacuum hose, thereby improving the efficiency of grain-rough separation and improving the work efficiency of the staff.

[0004] With respect to the above-mentioned and existing related technologies, the inventors believe that the following defects often exist: in actual use, due to the large number of grain types on the market, the separation screen cannot adjust the mesh size of the screen according to the size of different types of grains, making the separation screen unable to be used for screening different grains, thereby reducing the practicality of the screening device.

[0026] Reference Figure 4 and Figure 5 As shown, in the present embodiment: a slide groove 10 is provided inside the limiting rod 8, a slider 11 is slidably connected inside the slide groove 10, an extension rod 12 is fixedly connected to the top of the slider 11, and the top of the extension rod 12 is fixedly connected to the top of the inside of the mounting shell 7. When the limiting rod 8 moves under the elastic force of the first spring 9, the sliding connection between the slider 11 and the slide groove 10 limits the moving trajectory of the limiting rod 8, limits the elastic force generated by the first spring 9, and prevents the limiting rod 8 from detaching from the inner wall of the mounting shell 7, so that the insertion of the limiting rod 8 and the limiting hole 6 is more stable.

[0027] Reference Figure 2 - Figure 5 As shown, in this embodiment: a push rod 13 is fixedly connected to the bottom of the limit rod 8, a plurality of square grooves 14 are opened on the surface of the limit hole 6, the square grooves 14 are connected to the limit hole 6, and the surface of the push rod 13 is slidably connected to the inner wall of the square groove 14.

Through the sliding connection between the first spring 9 and the extension rod 12, the first spring 9 can move closely against the extension rod 12, preventing the first spring 9 from curling up when rebounding and causing entanglement to affect the normal operation of the component, thereby improving the stability of the operation of the first spring 9.

The staff pulls the handle 17 to drive the sliding plate 16 to move back and forth on the surface of the second sliding rod 15, so that the brush 18 cleans the surface of the first screen 2, pokes the impurities blocked in the holes of the first screen 2, and dredges the first screen 2 and the second screen 4, so as to prevent the first screen 2 and the second screen 4 from being blocked by impurities after long-term use, thereby reducing the screening speed of the device.

[0030] Reference Figure 6 and Figure 7 As shown, in the present embodiment: three circular grooves 19 are provided on both sides of the inside of the slide plate 16, and a plurality of balls 20 are slidably connected inside the circular grooves 19, and the surfaces of the balls 20 are slidably connected to the surface of the second slide bar 15. When the staff pulls the slide plate 16 to move on the surface of the second slide bar 15, the plurality of balls 20 sliding on the inner walls of the circular grooves 19 are slidably connected to the second slide bar 15, thereby reducing the contact area between the slide plate 16 and the second slide bar 15, and reducing the friction resistance generated by the slide plate 16 sliding on the surface of the second slide bar 15, so that the slide plate 16 and the second slide bar 15 slide more smoothly, making it easier for the staff to pull the slide plate 16 and use the brush 18 to clean the first screen 2, thereby reducing the physical exertion of the staff in pulling the slide plate 16.

[0031] Reference Figure 6 and Figure 7 As shown, in the present embodiment: the surface of the second slide rod 15 is slidably connected with a second spring 21, one end of the second spring 21 is fixedly connected to the slide plate 16, and the end of the second spring 21 away from the slide plate 16 is fixedly connected to one side of the inside of the shell 1, when the staff pulls the slide plate 16 to move, the slide plate 16 pulls the second spring 21 to extend to accumulate force, and when the staff releases the slide plate 16, the force released by the second spring 21 rebounds and pulls the slide plate 16 to reset, and limits the initial position of the slide plate 16, so that the staff can repeatedly pull the slide plate 16 and use the brush 18 to clear the first screen 2.

[0032] Working principle: the staff pushes the limit rod 8 upward to press the first spring 9 to store force, then pulls the pull plate 5 to drive the second screen 4 to slide to the specified position on the surface of the first slide bar 3, and then releases the force generated by the first spring 9, so that the first spring 9 releases the force generated, rebounds downward and pushes the limit rod 8 downward to insert into the inner wall of the limit hole 6, fixes the position of the second screen 4, so that the mesh size of the first screen 2 and the second screen 4 are staggered, and the size of the falling mesh of the second screen 4 is adjusted, which is convenient for the staff to adjust the screening mesh number of the device, so that the device can be used for grains of different sizes, improving the practicality of the device. When moving under the elastic force of the spring 9, the sliding connection between the slider 11 and the slide groove 10 limits the movement trajectory of the limit rod 8, limits the elastic force generated by the first spring 9, prevents the limit rod 8 from detaching from the inner wall of the mounting shell 7, and makes the insertion of the limit rod 8 and the limit hole 6 more stable. The staff pushes the push rod 13 upward to make the limit rod 8 enter the inner wall of the mounting shell 7, so that the push rod 13 is placed in the inner wall of the square groove 14, and the position of the limit rod 8 is bound to the inner wall of the mounting shell 7, which is convenient for the staff to pull the pull plate 5 back and forth to adjust the position of the second screen 4. The sliding connection between the first spring 9 and the extension rod 12 allows the first spring 9 to move close to the extension rod 12 The first spring 9 is prevented from curling up and causing entanglement when rebounding, thereby affecting the normal operation of the component, thereby improving the stability of the operation of the first spring 9. The staff pulls the handle 17 to drive the slide plate 16 to move back and forth on the surface of the second slide bar 15, so that the brush 18 cleans the surface of the first screen 2, rams the blocked impurities in the holes of the first screen 2, and dredges the first screen 2 and the second screen 4, thereby preventing the first screen 2 and the second screen 4 from being blocked by impurities after long-term use and reducing the screening speed of the device. When the staff pulls the slide plate 16 to move on the surface of the second slide bar 15, a plurality of balls 20 sliding on the inner wall of the circular groove 19 are connected to the sliding of the second slide bar 15, reducing the slide plate The contact area between 16 and the second slide bar 15 increases the friction resistance generated by the sliding of the slide plate 16 on the surface of the second slide bar 15, making the sliding of the slide plate 16 and the second slide bar 15 smoother, making it easier for the staff to pull the slide plate 16 and use the brush 18 to clean the first screen 2, reducing the physical exertion of the staff in pulling the slide plate 16. When the staff pulls the slide plate 16 to move, the slide plate 16 pulls the second spring 21 to extend and store force. When the staff releases the slide plate 16, the force released by the second spring 21 rebounds and pulls the slide plate 16 to reset, and limits the initial position of the slide plate 16, making it easier for the staff to repeatedly pull the slide plate 16 and use the brush 18 to dredge the first screen 2.
