Example Embodiment

[0018] The technical solutions in the embodiments of the present invention will be clearly and completely described below with reference to the accompanying drawings in the embodiments of the present invention. Obviously, the described embodiments are only a part of the embodiments of the present invention, but not all of the embodiments. Based on the embodiments of the present invention, all other embodiments obtained by those of ordinary skill in the art without creative efforts shall fall within the protection scope of the present invention.
[0019] The present invention provides such as figure 1 , figure 2 and image 3 A kind of screening machine for water conservancy engineering shown, comprises screening main box 7, and the inner wall of described screening main box 7 is provided with transmission system 9, and the bottom of described transmission system 9 is provided with double-layer screening net 2, and described screen The upper surface of the sub-main box 7 is provided with a hand-controlled pull ring 10, the right side of the sieving main box 7 is provided with a feed hopper 1, and the left side of the sieving main box 7 is provided with an outlet 8 for the screened product. The screen main box 7 is provided with an under-screen product outlet 5 on the front, and the bottom of the under-screen product outlet 5 is provided with an air extraction device 6, and the bottom of the screen main box 7 is provided with a magnetic motor 3. The bottom of the magnetic motor 3 is provided with a support chassis 4 .
[0020] Specifically, the double-layer screen 2 includes a primary screen 202 and a secondary screen 201, the primary screen 202 is arranged on the upper surface of the double-layer screen 2, and the secondary screen The subnet 201 is arranged at the bottom of the primary screening net 202 .
[0021] Specifically, the upper surface of the support chassis 4 is provided with threads, and the support chassis 4 and the screening main box 7 are rotatably connected by threads.
[0022] Specifically, the suction device 6 includes a suction nozzle 601 and a vacuum pump 602 , the suction nozzle 601 is arranged on the left side of the suction device 6 , and the vacuum pump 602 is arranged on the right side of the suction nozzle 601 .
[0023] Specifically, the angle between the feed hopper 1 and the transmission system 9 is set to 90°.
[0024] Specifically, there are 8 manual control rings 10, and the 8 manual control rings 10 are symmetrically arranged on both sides of the screening main box 7 respectively.
[0025] Working principle: When using this kind of screening machine for water conservancy projects, first turn on the power, the magnetic motor 3 starts to work, pour the material from the feeding hopper 1, and the suction device 6 starts to suck, and the material is screened by double layers. After the screen 2 is sieved, the smaller particles are discharged through the outlet 5 of the under-sieve product, while the larger particles are discharged through the outlet 8 of the over-sieve product.
[0026] Finally, it should be noted that the above descriptions are only preferred embodiments of the present invention, and are not intended to limit the present invention. Although the present invention has been described in detail with reference to the foregoing embodiments, for those skilled in the art, the The technical solutions recorded in the foregoing embodiments can be modified, or some technical features thereof can be equivalently replaced, and any modifications, equivalent replacements, improvements, etc. made within the spirit and principles of the present invention shall be included. within the protection scope of the present invention.
