Problems solved by technology

[0003] In the process of building construction, in order to prepare the required concrete mortar, the sand needs to be screened to obtain relatively fine sand particles that meet the requirements of use. However, the current sand screening device is likely to cause excessive accumulation of sand during the sand screening process. , the sand is not easy to be fully dispersed, resulting in a greatly reduced screening efficiency, which directly restricts the screening effect of the sand. Therefore, a high-efficiency sand screening device for construction is now provided to solve the above technical problems

Embodiment 1

[0021] see Figure 1-3 , a high-efficiency sand screening device for building construction, including a load-bearing base plate 1, a support frame 3 is vertically fixed on the load-bearing base plate 1, a support limit ring 11 is provided on the support frame 3, and a screen is installed in the support limit ring 11. Subnet cylinder 14, the left side of described screening net cylinder 14 is provided with servomotor 19, and the output shaft of servomotor 19 is coaxially fixed with the driving shaft 9 that extends to the screening net cylinder 14, is fixed on the driving shaft 9 and is positioned at The spiral blade 12 in the screen cylinder 14,

[0022] The screen cylinder 14 is used to load the sand to be screened. The servo motor 19 drives the drive shaft 9 to rotate. The drive shaft 9 drives the screw blade 12 to rotate. The sand in the sub-net cylinder 14 moves back and forth laterally and is broken up and dispersed, and the dispersed sand is screened by the sieving net c...

Embodiment 2

[0026] On the basis of embodiment 1, in addition, on the support frame 3, the horizontal rotation type is provided with the driven shaft 23 that is connected with the driving shaft 9 through the pulley mechanism I10, and the driven shaft 23 surface is fixed with several screen cylinders 14 The cleaning brush plate 20 abutted on the outer surface, the rotation of the drive shaft 9 drives the driven shaft 23 to rotate through the pulley mechanism I10, and the driven shaft 23 drives the cleaning brush plate 20 to rotate and clean the outer surface of the screen cylinder 14, which promotes the screening process. The unimpededness of the net hole on the net cylinder 14 has accelerated the screening effect of sand.

[0027] Further, driving shaft 9 right-hand ends are fixed with driving bevel gear 8, and driving bevel gear 8 right side rotation type is vertically provided with transmission shaft 6, and transmission shaft 6 upper ends are fixed with driven bevel gear 7 meshing with dr...

Abstract

The invention discloses a high-efficiency screening device for building construction and relates to the technical field of construction machinery. The high-efficiency screening device for the buildingconstruction is characterized in that the high-efficiency screening device comprises a bearing base plate; a support frame provided with a support limit ring is vertically fixed on the bearing base plate; the support limit ring is internally rotatably installed with a sieve screening cylinder whose left side is provided with a servo motor; a transmission gear engaged with an inner gear ring is sleeved and fixed on a rotary shaft; a collection tank located below the sieve screening cylinder is fixed on the bearing base plate. The high-efficiency screening device for the building construction has the advantages of realizing the rotary reciprocating motion of sand in the sieve screening cylinder, realizing the scattering effect of the sand, promoting the dispersion of the sand and improvingthe screening efficiency of the sand through positive and negative rotation of helical blades, further promoting the dispersion of the sand with the sieve screening cylinder and helical blades in reverse rotation, and realizing effective cleaning on the surface of the sieve screening cylinder, ensuring the smoothness of the mesh of the sieve screening cylinder and improving the screening efficiency of the sand with a driven shaft to drive a cleaning brush plate to rotate while moving left and right to reciprocate.

Description

technical field [0001] The invention relates to the technical field of construction machinery, in particular to a high-efficiency sand screening device for construction. Background technique [0002] Building construction refers to the production activities in the implementation stage of engineering construction. It is the construction process of various buildings. It can also be said to be the process of turning various lines on the design drawings into real objects at designated locations. It includes basic engineering construction, main structure construction, roofing engineering construction, decoration engineering construction, etc. The place where the construction works is called "construction site" or "construction site", also called construction site. [0003] In the process of building construction, in order to prepare the required concrete mortar, the sand needs to be screened to obtain relatively fine sand particles that meet the requirements of use. However, the...
