Referring to fig. 1-3, the present invention provides a technical solution:
a sand screening net device for building construction comprises two bases 1, wherein a supporting plate 2 is fixedly arranged at the top of one side, close to each other, of each base 1, a rotating shaft 3 is rotatably connected to one side, close to the inside, of each supporting plate 2, a screen 4 is arranged above each base 1, a mounting plate 5 is fixedly arranged on the left side of each screen 4, a fixing plate 6 is fixedly arranged on the right side of each screen 4, a gear 7 is fixedly arranged at the right end of each rotating shaft 3 on the right side, a motor 8 is fixedly arranged at the top of each base 1 on the right side, a half-tooth gear 9 is fixedly arranged at the output end of each motor 8, a protective shell 10 is fixedly arranged on the right side of each supporting plate 2 on the right side, a material receiving box 11 is arranged below each screen 4, sliding grooves 12 are respectively formed in two sides of the inner wall of each material receiving box 11, a material pushing plate 13 is slidably connected to the inside each material receiving box 11, connecting shafts 14 are respectively fixedly arranged at two ends of each material pushing plate 14, connecting shafts are rotatably connected to connecting rods 15, and fixing rods 16 are respectively arranged at the bottoms of two sides of each screen 4; in the using process, firstly, the motor 8 is turned on, the motor 8 drives the half-tooth gear 9 to rotate, the half-tooth gear 9 drives the gear 7 to rotate, the gear 7 drives the screen 4 to rotate through the rotating shaft 3, and meanwhile, the screen 4 is enabled to generate left-right shaking under the limitation of the half-tooth gear 9, so that sand inside the screen 4 is screened, when the screen 4 rotates, the connecting rod 15 is driven to move through the fixing rods 16 connected at two ends, the connecting rod 15 drives the material pushing plate 13 to slide inside the material receiving box 11 through the connecting shaft 14, and therefore the sand inside the material receiving box 11 is pushed to two sides of the material receiving box 11; this structure can be filtered the inside sand of screen cloth 4 through motor 8 to slope setting through screen cloth 4 can filter the great particulate matter that contains in the sand, and flow through the lower one end of screen cloth 4, has improved the efficiency that the sand was screened greatly, has alleviateed constructor's intensity of labour.
Specifically, the left side of the mounting plate 5 and the right side of the fixing plate 6 are respectively connected and fixed with the two rotating shafts 3, so that the screen 4 can rotate and swing through connection with the rotating shafts 3.
Further, the half-tooth gear 9 is meshed with the gear 7, and the gear 7 can be rotationally swung under the action of the half-tooth gear 9 through meshing.
Furthermore, two ends of the material pushing plate 13 are respectively connected with the inner wall of the chute 12 in a sliding manner, and the fixed rod 16 is rotationally connected with the connecting rod 15; through setting up material receiving box 11 in screen cloth 4 bottom to at the inside scraping wings 13 that sets up of material receiving box 11, thereby promote the both sides of material receiving box 11 with the inside sand of material receiving box 11 through the swing of screen cloth 4, thereby the constructor of being convenient for uses.
