[0015] Preferably, the limiting plate and the bottom wall of the U-shaped plate are magnetically connected.

[0016] Compared with the prior art, the present invention has the following effects: 1. A rectangular frame is arranged by rotating inside the screening box, a screening frame is arranged in the rectangular frame, a plurality of screens are arranged in the screening frame from top to bottom for dividing the screening frame into a plurality of screening cavities, a first discharge port is arranged on the side wall of each screening frame, a second discharge port matched with the first discharge port is arranged at the bottom end of the screening box, a flexible telescopic tube and a sealing component connected to the free end of the flexible telescopic tube are arranged in each first discharge port, and a second limiting component for limiting the sealing component to the first discharge port is arranged, so that after the screening is completed, the screening frame can be rotated 90 degrees, so that the first discharge port can be directly opposite to the second discharge port on the bottom wall of the screening frame, and then the second limiting component is unlocked to make the sealing component fall below the second discharge port under the action of gravity, and during the falling process of the sealing component, the flexible telescopic tube is extended accordingly, so that the raw materials in the screening cavity fall into the flexible telescopic tube, and then the sealing component is opened to smoothly collect the raw materials.

[0017] Through the synergistic effect of the above-mentioned devices, the raw materials in each screening cavity can be collected, thereby improving the convenience of collection.

[0018] However, as the screening frame rotates 90 degrees, the raw materials in the screening chamber below may enter the screening chamber above along the screen, resulting in the mixing of the raw materials, thereby making the raw materials collected in each screening chamber insufficiently screened. Based on this, the present invention provides a strip opening on the side wall of each screening chamber, and provides U-shaped rods with the same number as the strip opening on the side wall of the rectangular frame, and a first telescopic plate capable of horizontally passing through the strip opening is provided on each U-shaped rod, and a first connecting plate is provided at the telescopic end of each first telescopic plate, and a first hydraulic rod with the same number as the first telescopic plate and the telescopic end being detachably connected to the first connecting plate is provided on the side wall of the screening box. After the raw material screening is completed and before the screening frame is rotated, multiple first hydraulic rods can be started, so that the telescopic end of the first hydraulic rod is aligned with the first connecting plate and moves toward the strip opening, and the first connecting plate is pushed to move toward the strip opening after contacting the first connecting plate. In this process, the first connecting plate drives the telescopic end of the first telescopic plate to move toward the strip opening, thereby gradually lengthening the first telescopic plate until its free end moves to abut against the inner wall of the screening frame, and then the screening frame can be rotated to retain the raw materials for collection.

[0019] Through the coordinated action of the above-mentioned first telescopic plate, first hydraulic rod and other devices, the technical problem of cross-mixing of raw materials in adjacent screening chambers passing through the screen during the 90-degree rotation of the screening frame can be effectively avoided, thereby effectively improving the screening adequacy of the collected raw materials.

[0020] 2. By arranging the first electromagnet at the telescopic end of the first hydraulic rod and limiting the magnetic connection between the first electromagnet and the first connecting plate after being energized, the first electromagnet can be de-energized after the first telescopic plate is extended, so that the first hydraulic rod and the first connecting plate can be separated, thereby making the first hydraulic rod and the first connecting plate detachable, thereby effectively improving the flexibility of use of the device.

[0021] 3. By setting a horizontal vibration component including a second fixed plate, a second movable plate, a second spring, an impact rod, etc., the screening frame can be vibrated in the horizontal direction after the screening frame is rotated 90 degrees, so that the raw materials remaining on the inner wall of the screening frame and the inner wall of the screen can fall quickly into the first discharge port under the action of vibration, thereby avoiding the raw materials remaining in the screening frame and effectively improving the raw material yield.

[0022] 4. By setting up the U-shaped plate, the fifth hydraulic rod, the third electromagnet, the sixth hydraulic rod, the limit rod, the limit ring, the limit plate and other devices, the top of the limit ring can be moved to abut against the side wall of the screening frame after the material is taken. In this way, the flexible telescopic tube can be limited by the multiple limit rods arranged outside the flexible telescopic tube, ensuring that it always moves vertically during the contraction process and is slidably connected with the limit rods during the movement to ensure smooth contraction. In addition, under the magnetic connection between the fifth hydraulic rod and the sealing assembly, the flexible telescopic tube can be made to be completely vertical before contraction, and then the sealing assembly and the flexible telescopic tube are automatically returned to their original positions under the action of the fifth hydraulic rod, ensuring the smooth return of the sealing assembly and the flexible telescopic tube, and improving the smoothness of operation.

The first telescopic plate 8 is composed of a plurality of displacement plates distributed up and down (the connection relationship between the plurality of displacement plates is not shown in the figure), and the adjacent displacement plates are slidably connected, wherein the adjacent displacement plates are close to each other, and a limiting slider is provided on one side, and a limiting slot is provided on the other side, so as to ensure that the first telescopic plate 8 can be extended and retracted smoothly, and at the same time ensure that the displacement plate will not be separated. Among them, the limiting slider and the limiting slot are both prior art and are not shown in the figure.

[0026] like Figure 7-Figure 9As shown, the discharge assembly includes a flexible telescopic tube 11 (such as a PVC transparent telescopic steel hose) fixedly arranged in the first discharge port 6, a sealing assembly detachably arranged in the first discharge port 6 and connected to the free end of the flexible telescopic tube 11, and a second limiting assembly for limiting the sealing assembly to the first discharge port 6; the flexible telescopic tube 11 is stored in the first discharge port 6 in a contracted state; The apertures of the sieve holes of the multiple sieves 4 distributed up and down gradually decrease from top to bottom. The side walls and bottom walls of the screening frame 3 are both provided with multiple sieve holes, and the apertures of the sieve holes provided on the side walls and bottom walls of the screening frame 3 are all smaller than the aperture of the sieve holes of the lowest sieve 4.

[0027] Further, such as Figure 3 , Figure 4 and Figure 6 As shown, the telescopic end of the first hydraulic rod 9 is provided with a first electromagnet 12 (existing technology, i.e., magnetism is generated when energized and the magnetism disappears when powered off), the first electromagnet 12 can contact the first connecting plate 10, and the first electromagnet 12 is magnetically connected to the first connecting plate 10 after being energized.

[0028] Further, such as Figure 3 , Figure 4 and Figure 6 As shown, the sealing assembly includes a connecting ring 13 detachably arranged in the first discharge port 6, and a cover plate 14 arranged in the connecting ring 13; one end of the flexible telescopic tube 11 is fixedly connected to the inner wall of the first discharge port 6, and the other end is fixedly connected to the connecting ring 13; Figure 8 As shown, after the flexible telescopic tube 11 is naturally extended, its length is longer than the distance between the first discharge port 6 and the second discharge port 7 directly below it; like Figure 7-Figure 9 As shown, the second limiting assembly includes a first limiting groove 15 arranged on the inner wall of the first discharge port 6, a second electromagnet 19 (existing technology) arranged in the first limiting groove 15, a first spring 16 arranged on the side wall of the second electromagnet 19, an iron block 17 arranged on the end of the first spring 16 away from the second electromagnet 19 and slidably connected to the first limiting groove 15, a limiting plug arranged on the side of the iron block 17 away from the first spring 16, and a second limiting groove 18 arranged on the outer wall of the connecting ring 13 and adapted to the limiting plug.

[0029] In addition, when the first telescopic plate 8 is extended to abut against the inner wall of the screening box 1, the first connecting plate 10 and the inner wall of the screening box 1 are magnetically connected, wherein the magnetism between the first electromagnet 12 and the first connecting plate 10 is greater than the magnetism between the first telescopic plate 8 and the inner wall of the screening box 1.

[0030] like Figure 7 and Figure 8 As shown, the side wall of the screening box 1 is arranged to be inclined along the direction of the first discharge port 6 .

[0031] Furthermore, the cover plate 14 and the connecting ring 13 are threadedly connected.

[0032] like Figure 1 , Figure 2 and Figure 5 As shown, the vertical vibration assembly includes a plurality of third springs arranged between the screening frame 3 and the top and bottom ends of the rectangular frame 2, a telescopic rod 48 arranged outside the third springs, and a vibration motor 35 arranged at the bottom end of the screening frame 3.

[0033] like Figure 1 As shown, one end of the rotating shaft passes through the side wall of the screening box 1 and is connected to a hand wheel 49 ; the other end of the rotating shaft is fixedly connected to a cross bar 55 arranged on the side wall of the rectangular frame 2 .

[0034] like Figure 2 As shown (in all drawings, only Figure 2 The first limiting component is drawn), and the first limiting component includes two seventh hydraulic rods 51 arranged on the bottom wall of the screening box 1, a sliding plate 52 arranged at the top of the seventh hydraulic rod 51 and slidably connected to the inner wall of the screening box 1, a plurality of second limiting columns 56 arranged at the top of the sliding plate 52, and a limiting hole (existing technology, not drawn in the figure) arranged at the bottom end of the rectangular frame 2 and on the outer wall of the rectangular frame 2 on the side close to the first discharge port and adapted to the second limiting column 56.

[0035] Further, such as Figure 1 , Figure 2 and Figure 6 As shown, a feed port is provided at the top of the screening frame 3, and a feed pipe 50 is threadedly connected to the feed port. The top of the feed pipe 50 passes through an opening provided at the top of the screening box 1 and extends to the outside of the screening box 1.

[0036] It is worth noting that, in the present invention, the hydraulic cylinder of the first hydraulic rod 9 is arranged on the side wall of the screening box 1 , which can reduce the space occupied by the first hydraulic rod 9 in the screening box 1 and significantly improve the space utilization rate in the screening box 1 .

[0037] Working principle: first, by turning the hand wheel 49, the rectangular frame 2 is rotated to a horizontal state, and then the seventh hydraulic rod 51 is started to move the sliding plate up until the second limit column 56 at the top of the sliding plate 52 moves into the limit hole to fix the rectangular frame 2 to the screening box 1. Then, the raw material is added to the screening frame 3 through the feed pipe 50. After the addition is completed, the vibration motor 35 is started. Under the action of the vibration motor 35, the rectangular frame 2 and the raw material therein are vibrated in the vertical direction, and the purpose of grading and screening is achieved during the vibration process. The raw material with the smallest particle size directly falls to the bottom of the screening box 1 through the sieve holes on the side wall and bottom wall of the screening frame 3 (it is worth noting that each of the second discharge ports 7 is provided with a plugging plate or a piston, which is not shown in the figure because the plugging plate or the piston is a prior art). After the screening is completed, the plugging plate or the piston is removed, and the raw material falling to the bottom wall of the screening box 1 can be collected. In addition, it is necessary to rotate the feed pipe 50 to remove the feed pipe 50 from the screening frame 3.

[0038] Afterwards, the three first hydraulic rods 9 are started synchronously, so that the telescopic end of the first hydraulic rod 9 is aligned with the first connecting plate 10 and moves until the first electromagnet 12 contacts the first connecting plate 10 matched therewith, and then the first hydraulic rod 9 continues to be extended, and the connecting plate and the first telescopic plate 8 are pushed through the strip opening 5 and moved to the inside of the screening box 1 until they abut against the side of the screening box 1 where the first discharge port 6 is set. At this time, the first connecting plate 10 is magnetically connected to the inner wall of the screening box 1.

[0039] Thereafter, the first hydraulic rod 9 is returned to its original position, and the second limiting column is disengaged from the limiting hole, and then the hand wheel 49 is rotated to rotate the rectangular frame 2 90 degrees toward the front side of the screening box 1 (such as Figure 7 , Figure 8 and Fig.10 As shown), the seventh hydraulic rod 51 is then activated to move the sliding plate upward until the second limiting column 56 at the top of the sliding plate 52 moves into the limiting hole to fix the rotated rectangular frame 2 to the screening box 1. Figure 8 As shown, the second electromagnet 19 is energized to move the iron block 17 toward the second electromagnet 19, thereby moving the limiting plug out of the second limiting groove 18. Figure 7 The structure becomes Figure 8 and Fig.10 ( Fig.10 is Figure 6 Under the action of gravity, the connecting ring 13 and the cover plate 14 fall down and drive the flexible telescopic tube 11 to fall down and extend. The connecting ring 13 and the cover plate 14 pass through the second discharge port 7 and are located below the second discharge port 7. Afterwards, the cover plate 14 is removed, and the raw materials in each second discharge port 7 can be collected.

[0040] After the collection is completed, the cover plate 14 is closed and moved upward. This process requires the staff to extend their hands into the screening box 1 along the second discharge port 7 to operate. During the upward movement, the flexible telescopic tube 11 continuously contracts until it is retracted into the first discharge port 6 again, and then the second electromagnet 19 is de-energized to achieve the limit of the sealing assembly.

[0041] Thereafter, the rectangular frame 2 is rotated to the original position (i.e., the position during screening), and the first hydraulic rod 9 is started again so that its telescopic end passes through the strip opening 5 and contacts the first connecting plate 10, and then the first electromagnet 12 is energized to magnetically connect the first connecting plate 10 and the first electromagnet 12, and then the first hydraulic rod 9 is retracted to move the first connecting plate 10 and the first telescopic plate 8 out of the screening box 1. During this process, the first telescopic plate 8 is continuously retracted until it moves to the original position, and then the first electromagnet 12 is de-energized to separate the first electromagnet 12 and the first connecting plate 10, and finally the first hydraulic rod 9 is returned to the original position.

[0042] Afterwards, the next batch of raw material screening operations can be carried out normally.

[0043] Example 2 In Example 1, the method of discharging the material by rotating the screening frame 3 by 90 degrees is a static discharging method. This method will make it difficult to completely discharge the raw materials remaining in the screen 4 and the sieve holes of the screening frame 3, thereby resulting in incomplete collection of the raw materials. Based on this, on the basis of Example 1, as Fig.13 and Fig.14 As shown, the screening device further includes a horizontal vibration component which is arranged on the side wall of the screening frame 3 (i.e., the side of the screening box 1 away from the first hydraulic rod 9) and can drive the screening frame 3 to vibrate in the horizontal direction; Fig.15 As shown, each U-shaped rod 53 is provided with a slider at the end thereof (not shown in the prior art), and the rectangular frame is provided with a vertical slide groove 22 that is slidably matched with the slider. Fig.16 As shown, a through groove 23 is provided on the side wall of the screening box 1 (i.e., a side of the screening box 1 on which the first hydraulic rod 9 is provided), and a first movable plate 24 is slidably provided in the through groove 23, and a plurality of the first hydraulic rods 9 are all provided on the first movable plate 24; a first fixed plate 25 is provided on the outer wall of the screening box 1, and a second hydraulic rod 26 is provided on the first fixed plate 25, and a telescopic end of the second hydraulic rod 26 is fixedly connected to the first movable plate 24 via a second connecting plate; a second telescopic plate 54 is provided between the top end of the first movable plate 24 and the top end of the through groove 23, and when the first movable plate 24 is at the bottom end of the through groove 23, the first electromagnet 12 on the first hydraulic rod 9 is just aligned in the horizontal direction with the first connecting plate 10 on the U-shaped rod 53 located at the bottom end of the vertical slide groove 22 at this time.

[0044] Further, such as Fig.13 and Fig.14 As shown, the horizontal vibration assembly includes a second fixed plate 27 arranged on the side wall of the screening box 1 (i.e., the side of the screening box 1 away from the first hydraulic rod 9), a second movable plate 28 slidably arranged on the second fixed plate 27, a third hydraulic rod 29 arranged on the second fixed plate 27 and the telescopic end of which is fixedly connected to the side of the second movable plate 28 away from the screening box 1, a strip groove arranged at the top of the second movable plate 28, a second spring 30 arranged on the inner wall of the strip groove, and a movable plate 28 arranged at the telescopic end of the second spring 30 and slidably connected to the strip groove. A movable block, a striking rod 31 horizontally arranged at the top of the movable block, a vertical plate 32 arranged at the top of the second movable plate 28 and located on both sides of the strip groove, a rotating rod 33 rotatably arranged between the two vertical plates 32, an eccentric wheel 34 sleeved on the outside of the rotating rod 33 and capable of contacting one end of the striking rod 31, and a motor 35 arranged on the side wall of one of the vertical plates 32 and the output end of which is connected to one end of the rotating rod 33; the end of the striking rod 31 away from the eccentric wheel 34 passes through the side wall of the screening box 1 and extends to the inside of the screening box 1. It is worth noting that the present invention arranges the main components of the horizontal vibration assembly on the outer wall of the screening box 1, which can reduce its occupied space in the screening box 1 and significantly improve the space utilization rate in the screening box 1.

[0045] Working principle: When the screening frame 3 rotates 90 degrees to unload materials, the third hydraulic rod 29 is started to make the second movable plate 28 and the parts thereon move synchronously toward the screening box 1. When one end of the impact rod 31 extending into the screening box 1 (the impact rod 31 is slidably connected to the side wall of the screening box 1) is about to touch the screening frame 3, the movement is stopped, and then the motor 35 is started to make the rotating shaft drive the eccentric wheel 34 to rotate, thereby striking the end of the impact rod 31 located outside the screening box 1, so that the impact rod 31 can vibrate in the horizontal direction, so that the end away from the eccentric wheel 34 strikes the screening frame 3 in the horizontal direction, thereby causing the screening frame 3 to vibrate in the horizontal direction, thereby causing the raw materials remaining in the screening frame 3 to fall off quickly, effectively improving the collection rate and collection efficiency. In actual implementation, an impact plate or a U-shaped impact rod can be set at one end of the impact rod 31 located in the screening box 1, wherein when the impact plate is set, the outer diameter of the impact plate is larger than the inner diameter of the feed port, and when the U-shaped impact rod is set, the two free ends of the U-shaped impact rod hit the screening frame 3 at non-feed port positions, but on both sides of the feed port. In this way, the technical defect of impact failure caused by the impact rod 31 hitting into the feed port can be avoided.

[0046] Since the height and width of the screening frame 3 may be different in actual implementation, the distance between the screening frame 3 and the side of the screening box 1 provided with the horizontal vibration component is different before and after the screening frame 3 is rotated. The horizontal vibration component provided in this embodiment will not cause any interference to the screening operation of the screening frame 3, and can also adapt to the horizontal vibration requirements of different distances between the screening frame 3 and the side of the screening box 1 provided with the horizontal vibration component after the screening frame 3 is rotated 90 degrees.

[0047] In addition, when the screening frame 3 vibrates horizontally, the U-shaped plate 40 and the first telescopic plate 8 are driven to vibrate accordingly, thereby causing the slider to slide in the vertical slide groove 22 adapted thereto, thereby adapting to the horizontal vibration of the screening frame 3 .

[0048] After the raw materials are completely collected, the screening frame 3 is rotated to the original position. At this time, under the gravity of the rectangular frame and the first telescopic plate 8 thereon, the slider will automatically move down to the bottom of the vertical slide 22. When the telescopic plate is needed after the next batch of raw materials is screened, that is, before the screening frame 3 is rotated 90 degrees, the first hydraulic rod 9 is first started to extend the first hydraulic rod 9 until the first electromagnet 12 contacts the connecting plate, and then the second hydraulic rod 26 is started to move the movable plate up until it moves to a position matching the strip opening 5. After that, the first telescopic plate 8 can be smoothly pushed in the manner of Example 1.

[0049] The second telescopic plate 54 can not only adapt to the up and down movement of the first movable plate 24, but also block the through slot 23 above the first movable plate 24 to prevent the raw materials from leaking out during screening.

[0050] Example 3 In Example 2, when unloading, the flexible telescopic tube 11 itself is in a certain elongated state (such as under the gravity of the connecting ring 13). When the screening frame 3 vibrates horizontally, the flexible telescopic tube 11 will be continuously pulled in order to adapt to the deformation, thereby causing it to continuously move up and down. When moving, it will continuously collide and rub against the inner wall of the second discharge port 7, affecting the service life of the flexible telescopic tube 11. At the same time, during the continuous movement of the flexible telescopic tube 11, the connecting ring 13 at its bottom end will also change position, thereby causing the position of the discharge port to change, which is not conducive to smooth material connection.

[0051] Based on this, on the basis of Example 2, as Fig.11 and Fig.12 As shown, two third movable plates 38 are parallelly and slidably arranged on the bottom wall of the screening box 1, and the ends of the two third movable plates 38 that are away from each other are respectively connected to the fourth hydraulic rod 37 arranged at the bottom end of the screening box 1, and the ends of the two third movable plates 38 that are close to each other are respectively provided with first limiting columns 39, and the outer wall of the connecting ring 13 is provided with a socket adapted to the first limiting column 39.

[0052] Working principle: When the connecting ring 13 falls below the second discharge port 7, the fourth hydraulic rod 37 is activated to move the two moving plates toward each other until the first limiting posts 39 on the two moving plates are inserted into the sockets on the outer wall of the connecting ring 13, so as to limit the connecting ring 13 to a certain height below the screening box 1. Figure 1 As shown, at this time, the flexible telescopic tube 11 is mainly located in the screen box, so the flexible telescopic tube 11 in the screen box 1 is in a bent state rather than a vertical state. When the screening frame 3 vibrates in the horizontal direction, the flexible telescopic tube 11 in the screen box 1 is deformed accordingly. During the deformation, the bent part moves in the horizontal direction, and there will be no large-scale collision or friction with the position of the second discharge port 7 due to the up and down movement, which effectively improves the service life of the flexible telescopic tube 11. At the same time, because the position of the connecting ring 13 is fixed, the material connection position does not change, ensuring the smoothness of the material connection. At the same time, when the flexible telescopic tube 11 is constantly vibrating horizontally with the screening frame 3, it can prevent the accumulation and residue of raw materials in the flexible telescopic tube 11, thereby improving the smoothness of material discharge.

[0053] Example 4 In Examples 1-3, manual operation is used to return the sealing component and the flexible telescopic tube 11 to their original positions. During manual operation, it is difficult for the staff to accurately move the sealing component to the corresponding position of the first discharge port 6, so that it is difficult for the sealing component to be limited to the first discharge port 6. Secondly, during the continuous upward movement of the sealing component, the flexible telescopic tube 11 is not in a vertical state, but is continuously bent, making it difficult for it to smoothly contract in the vertical direction. Based on this, on the basis of any one of Examples 1-3, as Figure 11-Figure 12 As shown, a U-shaped plate 40 is slidably provided on the bottom wall of the screening box 1, and a plurality of fifth hydraulic rods 41 adapted to the second discharge port 7 are provided on the U-shaped plate 40, and a third electromagnet 42 is provided at the telescopic end of the fifth hydraulic rod 41, and the third electromagnet 42 is magnetically connected to the cover plate 14 after being energized; a sixth hydraulic rod 43 is provided at the bottom end of the screening box 1, and the telescopic end of the sixth hydraulic rod 43 is fixedly connected to the U-shaped plate 40.

[0054] Further, such as Figure 11-Figure 12 As shown, the outside of each fifth hydraulic rod 41 is uniformly distributed with a plurality of limit rods 44 around the center of the telescopic end, and the tops of the plurality of limit rods 44 are commonly connected to a limit ring 45, and the bottom ends of all the limit rods 44 penetrate the bottom wall of the U-shaped plate 40 and are commonly connected to the limit plate 46, and when the limit plate 46 contacts the U-shaped plate 40, the limit ring 45 just contacts the side wall of the screening frame 3; the inner wall of the limit ring 45 and the inner wall of the limit rod 44 are respectively slidably connected to the outer wall of the flexible telescopic tube 11. Further, the limit plate 46 is magnetically connected to the bottom wall of the U-shaped plate 40.

[0055] Working principle: When the screening frame 3 is finished and rotated 90 degrees, the sixth hydraulic rod 43 is started to make the U-shaped plate 40 slide at the bottom of the screening box 1 until it slides to the bottom of the second discharge port 7 (the sixth hydraulic rod 43 is fully extended at this time), and then the three fifth hydraulic rods 41 are started to make the telescopic ends of the three fifth hydraulic rods 41 pass through the three second discharge ports 7 respectively and move up to contact the three cover plates 14, and then the third electromagnet 42 is energized to make it magnetically connected with the cover plate 14, and the limit of the second limit assembly is released, so that the three fifth hydraulic rods 41 drive the sealing assembly to move down until the connecting ring 13 moves to a position adapted to the first limit column 39, and then the connecting ring 13 is limited by the first limit column 39. Then the third electromagnet 42 is de-energized, and the U-shaped plate 40 returns to its original position.

[0056] After the material is taken, the U-shaped plate 40 is moved again to the bottom of the second discharge port 7 and the first limiting column 39 is released to fix the connecting ring 13, and the cover plate 14 is installed on the connecting ring 13, and then the fifth hydraulic rod 41 is extended until the third electromagnet 42 contacts and magnetically connects with the cover plate 14, and then the fifth hydraulic rod 41 is contracted to extend the flexible telescopic tube 11 from a slightly bent state to a vertical state, and then the limiting plate 46 is moved upward. During the upward movement of the limiting plate 46, the limiting ring 45 and the plurality of first limiting columns 39 are respectively connected to the connecting ring 13 and the outer surface of the flexible telescopic tube 11. The limiting plate 46 moves to contact the bottom wall of the U-shaped plate 40 and is magnetically connected. At this time, the limiting ring 45 just contacts the side wall of the screening frame 3. Then, the fifth hydraulic rod 41 is started to move the sealing assembly upward. During the upward movement, the flexible telescopic tube 11 is always slidably connected with the limiting rod 44. Due to the limiting effect of the first limiting column 39, it can ensure that the flexible telescopic tube 11 is always in a vertical state, so that it can be smoothly contracted in the vertical direction until it is completely stored in the first discharge port 6. When the fifth hydraulic rod 41 is fully extended, the connecting ring 13 is just in the original position. Then, the third electromagnet 42 is powered off to return the fifth hydraulic rod 41, the limiting ring 45 and the limiting rod 44 to their original positions. Further, on the basis of any one of Examples 1-4, Fig.17 As shown, each of the strip-shaped openings 5 ​​is hinged with an inwardly opened baffle 20, and the baffle 20 is provided with a plurality of sieve holes with the same aperture as the side wall of the screening frame 3; a return spring (not shown in the prior art) is provided at the hinge of the baffle 20, so that the baffle 20 can smoothly return to its original position after being opened. The baffle 20 can block the strip-shaped opening 5 to prevent the raw materials from leaking directly through the strip-shaped opening 5 during screening, resulting in insufficient screening of the raw materials obtained from the bottom wall of the screening box 1.
