Wherein, the feeding pipe 22 is rotatably connected with the frame 1, and the transverse position refers to the horizontal axis position of the screen drum 2.

Through setting up screen cylinder 2 and helical blade 3 that have sieve mesh 21, when sand and stone gets into the inside of screen cylinder 2, can be sieved along with the rotation of screen cylinder 2, because screen cylinder 2 is the tube-shape, so the screening is gone on at the sieve mesh 21 of screen cylinder 2 bottom, and the sieve mesh 21 on upper portion is in idle state, so dredging mechanism can conveniently dredge sieve mesh 21 and not influence the screening.

The sieve mesh 21 is dredged through the dredging mechanism, so that high efficiency can be guaranteed in the screening process all the time on one hand, and on the other hand, the automatic dredging mode does not need manual cleaning, so that equipment damage caused by the manual cleaning is avoided.

In this embodiment, as shown in fig. 2, the dredging mechanism is a plurality of swing needles 6 which are obliquely arranged, the upper ends of the swing needles 6 are rotatably connected with the frame 1 through return springs, and the lower ends of the swing needles 6 are inclined in the direction of the linear velocity of the upper end of the screen drum 2. The balance needle 6 is provided with a plurality of rows and columns, and corresponds to the sieve holes 21 which are turned to the upper part, preferably one-to-one correspondence, and when the positions of the sieve holes 21 blocked by sand and stones are found, the balance needle 6 strikes the sand and stones down, thereby realizing the purpose of dredging.

In this embodiment, as shown in fig. 3 and 4, a front cover 8 is attached to the front side of the screen drum 2, and the front cover 8 is fixedly mounted to the frame 1, and a discharge port 81 is provided at the lower end of the front cover 8. The larger sand and stones screened in the screen drum 2 are discharged from the front side of the screen drum 2, blocked by the front cover 8 in order to prevent splashing, and then discharged from the discharge port 81.

In this embodiment, as shown in fig. 1, the feeding mechanism 4 includes a conveying auger 41 located inside the feeding pipe 22 and a motor 42 for driving the conveying auger 41 to rotate, and a hopper 43 is provided at the upper end of the feeding pipe 22. Sand and stones are poured from the hopper 43, and the motor 42 drives the conveying auger 41 to rotate so as to convey sand and stones into the screen drum 2 for screening.

When the screen holes 21 are blocked by sand and stone, the sand and stone is hit by the balance needle 6 through the elasticity of the reset spring after the screen cylinder 2 rotates to the upper part and contacts with the balance needle 6, so that the sand and stone falls into the screen cylinder 2 again, and the dredging purpose is realized.

Example two

As shown in fig. 1 to 5, unlike the first embodiment, the dredging mechanism is a pressing roller 7 rotatably connected to the frame 1 in the present embodiment.
