[0002] River dredging is an important part of waterway dredging in water conservancy projects. Large dredging ships are often used to dig silt from the riverbed and transport it away. Most of this silt is wasted and has no practical effect. River silt often contains a lot of sand and gravel, which can be used as raw materials for construction. The silt can be cleaned and the sand that is beneficial to construction can be screened out from the river silt. Therefore, the corresponding silt screening device is needed.

[0003] The silt screening devices for hydraulic projects in the prior art can only screen the silt mixed with sand in a single direction when screening the sand that is beneficial to the construction, so that the silt can only be subjected to the force in a single direction. The resulting silt screening effect is poor, resulting in part of the silt still being mixed with the sand, which is not conducive to use.

[0004] Therefore, a water conservancy engineering silt screening device is needed to solve the problem that most of the silt screening devices in the prior art can only screen silt mixed with sand in a single direction, resulting in poor screening effect on silt. Utility Model Content

[0009] It is further worth mentioning that a plurality of interference grooves are evenly provided on the surfaces of both sides of the screen plate, and interference strips are inserted into the interference grooves. One side of the interference strip passes through the adjacent interference grooves and is fixed to the inner wall of the screening seat.

[0010] It should be further explained that two hydraulic cylinders are fixed to the other end of the top surface of the support seat, a limiting groove is provided at the middle position of the top surface of the support seat, and a movable block is slidably inserted inside the limiting groove.

[0011] Preferably, the output end of the hydraulic cylinder is fixed to the surface of the movable block at an adjacent position, a connecting rod is hinged on the top of the movable block, and the top of the connecting rod is hinged to the surface of the rotating seat.

[0012] Preferably, a limiting rod is fixed to the bottom of one end surface of the rotating seat, a limiting sleeve is provided on the outer peripheral sliding sleeve of the limiting rod, and one end of the limiting sleeve is fixed to the surface of the screening seat.

[0013] Compared with the prior art, the utility model provides a hydraulic engineering sediment screening device, which has at least the following beneficial effects:

[0014] (1) By starting the motor and controlling its rotation direction, the screening seat can make reciprocating motion in the horizontal direction, and the cam is rotated during the reciprocating motion, so that the screen plate can make reciprocating motion in the vertical direction, so that screening forces in multiple directions can be applied to the silt placed inside the screening seat, thereby improving the screening effect of screening out sand that is beneficial to construction, thereby improving the practicality of the device.

When the screening seat 4 moves along the water direction, the gear 19 can mesh with the tooth seat 20, so that the rotating rod 17 can rotate, thereby allowing the cam 18 to rotate, so that the surfaces at both ends of the cam 18 can alternately fit with the surface of the screening seat 4, and then cooperate with the extension, contraction and reset function of the spring telescopic rod 16, so that the screen plate 6 can reciprocate in the vertical direction to screen the sludge placed in the inner cavity of the screening seat 4.

[0023] Further as Figure 1 , Figure 2 and Figure 3As shown, it is worth specifically explaining that a rod groove 11 is provided at the top of the surface of one end of the rotating seat 2, and a threaded rod 12 is rotatably connected inside the rod groove 11, and a threaded sleeve 13 is threadedly connected to the outer circumference of the threaded rod 12, and one end of the threaded sleeve 13 is fixed to the surface of the screening seat 4, and a motor 14 is fixed to the surface of one side of the rotating seat 2, and one side of the threaded sleeve 13 passes through the rotating seat 2 and is fixed to the output end of the motor 14. By starting the motor 14 and controlling the output end of the motor 14 to rotate alternately in two directions, the inner cavity of the rod groove 11 can play a role of resisting and limiting the threaded sleeve 13, so that the threaded sleeve 13 can make the screening seat 4 reciprocate in the horizontal direction under the cooperation between the internal thread structure of its inner wall and the external thread of the outer circumference of the threaded rod 12.

[0024] Further as Figure 1 As shown, it is worth explaining in detail that a plurality of interference grooves 7 are evenly provided on the surfaces of both sides of the sieve plate 6, and interference strips 8 are inserted inside the interference grooves 7. One side of the interference strips 8 passes through the adjacent interference grooves 7 and is fixed to the inner wall of the screening seat 4. When the sieve plate 6 moves in the vertical direction, the inner wall of the interference groove 7 will interfere with the surface of the interference strips 8, thereby limiting the movement trajectory of the sieve plate 6 and making it more stable when moving in the vertical direction.

[0025] Further as Figure 1 As shown, it is worth explaining in detail that two hydraulic cylinders 21 are fixed to the other end of the top surface of the support seat 1, and a limiting groove 22 is provided at the middle position of the top surface of the support seat 1, and a movable block 23 is slidably inserted inside the limiting groove 22. The output end of the hydraulic cylinder 21 is fixed to the surface of the movable block 23 at the adjacent position, and the top of the movable block 23 is hinged with a connecting rod 24, and the top of the connecting rod 24 is hinged to the surface of the rotating seat 2. By starting the hydraulic cylinder 21, the output end of the hydraulic cylinder 21 can be extended, so that the movable block 23 can move in the horizontal direction, so that the connecting rod 24 can change its angle, so that the rotating seat 2 can drive the screening seat 4 to change its angle.

[0026] This solution has the following working process: in actual use, when the user needs to screen the silt to obtain sand that is beneficial to construction, by starting the motor 14 and controlling the output end of the motor 14 to rotate alternately in two directions, the inner cavity of the rod groove 11 can play a role of resisting and limiting the threaded sleeve 13, so that the threaded sleeve 13 can make reciprocating motion in the horizontal direction under the cooperation between the internal thread structure of its inner wall and the external thread of the outer peripheral surface of the threaded rod 12, thereby applying a left and right force to the silt placed inside the screening seat 4. In this process, when the screening seat 4 moves in the direction of moisture, the gear 19 can mesh with the tooth seat 20, so that the rotating rod 17 can rotate, so that the cam 18 can rotate, so that the surfaces at both ends of the cam 18 can alternately fit with the surface of the screening seat 4 and then cooperate with the spring telescopic rod 1 6 has an extension, contraction and reset function, so that the screen plate 6 can reciprocate in the vertical direction to screen the silt in the inner cavity of the screening seat 4, so that a vertical force can be applied to the silt inside the screening seat 4, so that screening forces in multiple directions can be applied to the silt inside the screening seat 4, thereby improving the screening effect of screening out sand that is beneficial to construction. When it is necessary to recover the sand remaining on the top of the screen plate 6 after the screening is completed, first open the sealing door 5 to make one end of the inner cavity of the screening seat 4 connected with the outside of the screening seat 4, and start the hydraulic cylinder 21 to extend its output end, so that the movable block 23 can move in the horizontal direction, so that the connecting rod 24 can change its angle, so that the rotating seat 2 can drive the screening seat 4 to change its angle, so that the sand accumulated on the top of the screen plate 6 can slide down under the action of gravity to complete the recovery.

[0027] According to the above working process, it can be known that: by starting the motor 14 and controlling its rotation direction, the screening seat 4 can reciprocate in the horizontal direction, and the cam 18 is rotated during the reciprocating motion, so that the screen plate 6 can reciprocate in the vertical direction, so that the silt placed inside the screening seat 4 can be subjected to screening forces in various directions, thereby improving the screening effect of screening out sand that is beneficial to construction, thereby improving the practicality of the device, and by starting the hydraulic cylinder 21, the movable block 23 can move in the horizontal direction, so that the connecting rod 24 can change its angle, so that the rotating seat 2 and the screening seat 4 can change their angles, so that after opening the sealing door 5, the remaining sand can slide from one end of the support seat 1, thereby further improving the convenience of using the device.

[0028] Further as Figure 4As shown, it is worth explaining in detail that a limiting rod 9 is fixed to the bottom of the surface of one end of the rotating seat 2, and a limiting sleeve 10 is provided on the sliding sleeve of the outer circumference of the limiting rod 9. One end of the limiting sleeve 10 is fixed to the surface of the screening seat 4. Since the limiting sleeve 10 can only slide on the outer circumference of the limiting rod 9, it can limit the movement trajectory of the screening seat 4. In addition, since the limiting rod 9 supports the limiting sleeve 10, the stability of the screening seat 4 is improved.

[0029] In summary: by starting the motor 14 and controlling its rotation direction, the screening seat 4 can make reciprocating motion in the horizontal direction, and in the process of its reciprocating motion, the cam 18 rotates, so that the screen plate 6 can make reciprocating motion in the vertical direction, so that it can exert screening forces in multiple directions on the sludge placed inside the screening seat 4, thereby improving the screening effect of screening out sand that is beneficial to construction, thereby improving the practicality of the device, and by starting the hydraulic cylinder 21, the movable block 23 can move in the horizontal direction, so that the connecting rod 24 can change its angle, so that the rotating seat 2 and the screening seat 4 can change their angles, so that after opening the sealing door 5, the remaining sand can slide from one end of the support seat 1, thereby further improving the convenience of use of the device, because the limit sleeve 10 can only slide on the outer peripheral surface of the limit rod 9, so that it can limit the movement trajectory of the screening seat 4, and because the limit rod 9 supports the limit sleeve 10, the stability of the screening seat 4 is improved.

[0030] The motor 14 and the hydraulic cylinder 21 can be purchased on the market. The motor 14 and the hydraulic cylinder 21 are equipped with a power supply, which is a mature technology in this field and has been fully disclosed, so they are not repeated in the specification.
