Before taking it out, a box body is placed at the bottom of the collecting box 13 to collect the smallest particles. Then, the bottom plate 18 is slid into the collecting box 13 again, and the collecting box 13 is taken out by the A slider 12. The sieve plate 15 is taken out by pulling the protrusion 16 to take out the medium particles. This method can make the screening effect more delicate.

[0027] The vibration mechanism includes a support rod 20, one end of which is fixedly connected to one side of the shell 1, an electric push rod 21 is fixedly connected to the middle part of the support rod 20, one end of the electric push rod 21 is fixedly connected to a bracket 22, one end of the bracket 22 is fixedly connected to a connecting piece 23, one end of the connecting piece 23 is fixedly connected to a spring 24, and one end of the spring 24 is fixedly connected to a bouncing ball 25. When screening, the electric push rod 21 is started, and the electric push rod 21 drives the bracket 22 and the connecting piece 23 to move telescopically, and the connecting piece 23 drives the spring 24 and the bouncing ball 25 to bounce on the screening drum 9, vibrating the screening drum 9, which can improve the screening effect.

[0028] A threaded hole is provided at the bottom of the front side of the shell 1, and a baffle 27 is threadedly connected to the inside of the threaded hole through a fixing bolt 26. A B handle 28 is fixedly connected to the front side of the baffle 27. When screening the raw materials, the personnel first fix the baffle 27 to the shell 1 using the fixing bolt 26, which can play a shielding role during screening to prevent the raw materials from leaking.

[0029] Support columns 29 are fixedly connected to the outer surface of the housing 1 on all sides, and a support plate 30 is fixedly connected to the bottom of the support column 29. The support column 29 and the support plate 30 both play a supporting and fixing role to stably support the housing 1.

[0030] The bottom of the support plate 30 is fixedly connected with a universal wheel 31, and the inner part of the universal wheel 31 is rotatably connected with a brake pad. The universal wheel 31 can move the housing 1 to a suitable position to improve convenience.

[0031] A stirring rod 32 is fixedly connected to the interior of the screening drum 9, and a stirring fan blade is fixedly connected to the surface of the stirring rod 32. Through the setting of the stirring rod 32, when the screening drum 9 is used to screen the raw materials, the stirring rod 32 can evenly break up the raw materials, making the screening of the raw materials more delicate.

[0032] Working principle: When screening the raw materials, the personnel first fix the baffle 27 on the housing 1 with the fixing bolt 26, which can play a shielding role during screening to prevent the raw materials from leaking out. Then, the raw materials are put into the screening drum 9 from one end, and the driving motor 8 is started. The driving motor 8 drives the screening drum 9 to rotate. The screening drum 9 can screen the raw materials when rotating, and the raw materials of different particles are screened out. When the screening drum 9 is screening, the internal stirring rod 32 rotates together, and the stirring rod 32 is used to evenly disperse the raw materials, so that The raw materials are screened more finely. Subsequently, the small particles of raw materials after screening leak out from the holes of the screening cylinder 9 and fall onto the screening plate 15 of the collecting box 13, and are screened again. The smallest particles of raw materials fall into the collecting box 13. When the screening cylinder 9 rotates for screening, each rotation will pass through the cleaning rod 11. The brush on the cleaning rod 11 is used to clean the screening cylinder 9 to prevent particles from clogging the holes of the screening cylinder 9 and affecting the screening efficiency. Subsequently, during screening, the external water source is connected to the water inlet pipe 7, and the water pump 2 is started. The water pump 2 uses the water inlet pipe 7 to draw water, which flows from the water outlet pipe 3 to the connecting pipe 4, and then flows from the connecting pipe 4 to the water storage pipe 5, and then sprays from the spray head 6. The water flow is adjusted to the minimum, and the spraying state is in the form of water mist, which can reduce dust but will not wet and agglomerate the raw materials of cement products. Subsequently, the electric push rod 21 is started during screening, and the electric push rod 21 drives the bracket 22 and the connecting piece 23 to move telescopically, and the connecting piece 23 drives the spring 24 and the bouncing ball 25 to bounce on the screening drum 9, vibrating the screening drum 9. , which can improve the screening effect. Subsequently, after the raw materials are screened, the baffle 27 is removed, the large particles are taken out from the screening cylinder 9, and the A handle 19 is pulled to take the bottom plate 18 out of the collection box 13. Before taking it out, a box body is placed at the bottom of the collection box 13 to collect the smallest particles. Subsequently, the bottom plate 18 is slid into the collection box 13 again, and the collection box 13 is taken out by the A slider 12. The sieve plate 15 is taken out by pulling the protrusion 16, and the medium particles are taken out. This method can make the screening effect more delicate.
