[0003] When screening sediment, most devices throw the sediment onto a shaking screen and screen the sediment through the vibration of the screen. However, during screening, if there is too much sediment on the surface of the screen, the sediment on the upper layer may be difficult to screen, and the staff is required to take it out and put it back in for secondary screening, which is not only time-consuming and labor-intensive, but also reduces work efficiency and is inconvenient for staff to use. Utility Model Content
[0004] In view of the above-mentioned prior art, the technical problem to be solved by the utility model is that the sediment accumulates on the screen, making it difficult to screen the upper sediment. The staff needs to repeatedly take out the sediment and put it back on the screen, which is time-consuming, labor-intensive and inconvenient for the staff to use.
[0005] In order to solve the above problems, the utility model provides a sediment screening device for port engineering, comprising a working box, wherein the middle parts of the upper and lower ends of the working box are respectively fixedly connected with a feeding trough and a discharging pipe, the front and rear inner walls of the working box are fixedly connected with two mounting blocks, the top of the mounting block is fixedly connected with a sliding rod, the outer rings of the plurality of sliding rods are slidably sleeved with a sieve plate, the outer ring sleeve of the sliding rod is provided with a spring, the spring is located below the sieve plate, the middle part of the lower end of the sieve plate is fixedly connected with a vibration motor, a discharging port is opened at the left end of the working box, the left end of the sieve plate is located in the discharging port, a collecting pipe is fixedly connected at the port of the discharging port, a placing table is provided on the left side of the working box, a material transporting barrel inclined toward the working box is fixedly connected at the upper end of the placing table, a rotating motor is fixedly connected at the upper end of the material transporting barrel, the output end of the rotating motor passes through the inner cavity of the material transporting barrel and is fixedly connected with an auger, the left end of the collecting pipe is fixedly connected with a rubber tube through a flange, the left end of the rubber tube is fixedly connected to the material transporting barrel, and a discharge pipe is fixedly connected between one end of the material transporting barrel close to the upper end of the working box and the working box.
[0006] In the above-mentioned sediment screening device for port engineering, sediment accumulation can be effectively avoided. Without the need for staff operation, the screened sediment can be directly put back onto the screen for multiple screenings, thereby improving work efficiency.
[0007] As a further improvement of the present application, the front end of the working box is fixedly inlaid with tempered glass, and the tempered glass is located directly in front of the sieve plate.
[0008] As a further improvement of the present application, the height between the mounting block on the left and the inner bottom wall of the working box is smaller than the height between the mounting block on the right and the inner bottom wall of the working box, and the screen plate is tilted as a whole and faces the left bottom.
[0009] As a further improvement of the present application, guide plates are fixedly connected to the front and rear inner walls of the working box, and the lower ends of the guide plates are inclined toward the discharge pipe.
[0010] As another improvement of the present application, the cross-sectional area of the left end of the collecting pipe is smaller than that of the right end, and the collecting pipe is tilted downward to the left as a whole.
[0011] As another improvement of the present application, two screws are rotatably connected between the left and right inner walls of the working box, and the right ends of the outer circles of the two screws are commonly threadedly sleeved with a sleeve plate, and an inner plate is slidably connected inside the sleeve plate.

[0013] To sum up, in actual application, the mud and sand mixture is put into the working box through the feed trough and falls on the screen plate. Starting the vibration motor can make the screen plate vibrate, thereby driving the spring to expand and contract, causing the screen plate to shake up and down, thereby screening the mud and sand. The inclined screen plate causes the mud and sand to move to the left and fall into the collecting pipe, and then enter the material transport barrel through the rubber tube. Then the rotating motor is started to drive the auger to rotate, and the mud and sand in the material transport barrel is moved upward and discharged into the working box through the discharge pipe for secondary screening. After repeated screening, the rubber tube can be disconnected from the collecting pipe, so that the sand and gravel can be discharged from the working box through the collecting pipe, thereby effectively avoiding the accumulation of mud and sand on the screen plate, reducing the difficulty of screening, and eliminating the need for staff to manually take and put many times, thereby improving work efficiency.

DETAILED DESCRIPTION
[0023] Two implementation modes of the present application are described in detail below with reference to the accompanying drawings.
[0024] The first implementation method:
[0025] Figure 1 It is shown that a sediment screening device for port engineering comprises a working box 1, a feed trough and a discharge pipe are fixedly connected to the middle of the upper and lower ends of the working box 1 respectively, a collecting pipe 7 is fixedly connected to the port of the discharge port, a placing table is provided on the left side of the working box 1, a material transporting cylinder 8 inclined toward the working box 1 is fixedly connected to the upper end of the placing table, and a tempered glass is fixedly inlaid at the front end of the working box 1, so that the staff can check the sediment screening situation through the tempered glass, and the tempered glass is located directly in front of the screen plate 4.
[0026] Figure 2 and Figure 3It is shown that: two mounting blocks 2 are fixedly connected to the front and rear inner walls of the working box 1, a sliding rod 3 is fixedly connected to the top of the mounting block 2, a plurality of sliding rods 3 are slidingly sleeved together with a sieve plate 4 on their outer rings, a spring 5 is sleeved on the outer ring of the sliding rod 3, the spring 5 is located below the sieve plate 4, a vibration motor 6 is fixedly connected to the middle part of the lower end of the sieve plate 4, a discharge port is opened at the left end of the working box 1, the left end of the sieve plate 4 is located in the discharge port, the discharge port can limit the height of the up and down movement of the sieve plate 4, and is convenient for the discharge of sand and gravel, a rotating motor 9 is fixedly connected to the upper end of the conveying barrel 8, the output end of the rotating motor 9 passes through the inner cavity of the conveying barrel 8 and is fixedly connected to an auger 10, and the rotating motor 9 drives the auger 10 rotates to transport the mud and sand at the bottom of the material transport barrel 8 to the upper end of the material transport barrel 8, and then discharge it through the discharge pipe 12. The left end of the collecting pipe 7 is fixedly connected with a rubber tube 11 through a flange. The rubber tube 11 connected by the flange can be removed, so as to facilitate the final discharge of sand and gravel. The rubber tube 11 is elastic, highly flexible and easy to place. The left end of the rubber tube 11 is fixedly connected to the material transport barrel 8, and a discharge pipe 12 is fixedly connected between the end of the material transport barrel 8 close to the upper end of the working box 1 and the working box 1. The front and rear inner walls of the working box 1 are fixedly connected with guide plates 13. Fine sand falls onto the surface of the guide plates 13 for easy discharge, and the lower ends of the guide plates 13 are inclined toward the discharge pipe.
[0027] Figure 4 It shows that the height between the mounting block 2 on the left and the inner bottom wall of the working box 1 is smaller than the height between the mounting block 2 on the right and the inner bottom wall of the working box 1, and the screen plate 4 is tilted as a whole. The tilted screen plate 4 facilitates the movement of sand and gravel to the left and toward the left bottom.
[0028] Figure 5 It is shown that the cross-sectional area of the left end of the collecting pipe 7 is smaller than that of the right end. The right end of the collecting pipe 7 is larger and used in conjunction with the screen plate 4, while the left end is smaller and used in conjunction with the rubber tube 11. The collecting pipe 7 as a whole is inclined downward to the left side.
[0029] When in use, the silt mixture is put into the working box 1 through the feeding trough so that it falls on the screen plate 4. Starting the vibration motor 6 can make the screen plate 4 vibrate, thereby driving the spring 5 to expand and contract, causing the screen plate 4 to shake up and down, thereby screening the silt. The inclined screen plate 4 makes the silt move to the left and fall into the collecting pipe 7, and then enter the material transport barrel 8 through the rubber tube 11. Then the rotating motor 9 is started to drive the auger 10 to rotate, so that the silt in the material transport barrel 8 moves upward and is discharged into the working box 1 through the discharge pipe 12 for secondary screening. After repeated screening, the rubber tube 11 can be disconnected from the collecting pipe 7, so that the sand and gravel are discharged from the working box 1 through the collecting pipe 7, thereby effectively avoiding the accumulation of silt on the sieve plate 4, which makes the upper silt difficult to be screened, and there is no need for the staff to manually take and put it many times, thereby improving the work efficiency.
[0030] The second implementation method:
[0031] Based on the first embodiment, this embodiment adds a screw 14, a sleeve plate 15, an inner plate 16, a pulley set 17 and a rocker 18, and the rest of the parts are consistent with the first embodiment.
[0032] Figure 6 and Figure 7 It is shown that: two screws 14 are rotatably connected between the left and right inner walls of the working box 1, and the right ends of the outer circles of the two screws 14 are commonly threadedly sleeved with a sleeve plate 15, and an inner plate 16 is slidably connected inside the sleeve plate 15, and the lower end of the inner plate 16 contacts the upper end of the sieve plate 4. When the sieve plate 4 shakes up and down, the inner plate 16 can also move up and down inside the sleeve plate 15, so that the lower end of the inner plate 16 is always in contact with the upper end of the sieve plate 4, which is convenient for sweeping the sand and gravel on the sieve plate 4, and the front and rear ends of the sleeve plate 15 are respectively in contact with the front and rear inner walls of the working box 1, the screw 14 and the sieve plate 4 are in a parallel state, and the right end of the screw 14 passes through the working box 1, and the outer circles of the two screws 14 are commonly fixedly sleeved with a pulley group 17, which facilitates the simultaneous rotation of the screws 14 at the front and rear ends, and the right end of the screw 14 located in the front is fixedly connected with a rocker 18, which facilitates the staff to rotate the screw 14.
[0033] During use, if there is a small amount of sand and gravel on the upper end of the screen plate 4 that shakes for a long time but cannot move, the rocker 18 can be turned to rotate the screw 14, so that the sleeve plate 15 and the inner plate 16 move to the left, and the sand and gravel on the upper end of the screen plate 4 are swept into the collecting pipe 7, thereby preventing the sand and gravel from clogging the screen plate 4.
[0034] In view of current practical needs, the protection scope of the above-mentioned implementation mode adopted in this application is not limited to this. Various changes made within the knowledge scope of technical personnel in this field without departing from the concept of this application still fall within the protection scope of this utility model.
