Description
Technical Field
[0001] The utility model relates to the technical field of civil engineering construction equipment, and in particular to a sand screening device for building construction. Background Art
[0002] Construction sand is an important material in the construction industry. It is generally used as a filling material in construction projects. After being fully mixed with cement, it can fill the gap between the foundation and the base, thereby improving the stability and bearing capacity of the foundation.

[0028] The following will be combined with the embodiments of the utility model to clearly and completely describe the technical solutions in the embodiments of the utility model. Obviously, the described embodiments are only part of the embodiments of the utility model, not all of the embodiments. Based on the embodiments of the utility model, all other embodiments obtained by ordinary technicians in this field without creative work are within the scope of protection of the utility model.
[0029] like Figures 1 to 7 As shown, the utility model provides a sand screening device for construction, comprising:
[0030] A sand screening box body 1, a sliding block 2 is fixedly connected to the right side of the inside of the sand screening box body 1, and a sliding groove 3 is opened on the right side of the upper end of the front surface of the sand screening box body 1;
[0031] A dispersion mechanism, which is arranged on the left side of the front surface of the sand screening box 1;
[0032] Among them, the dispersion mechanism includes a No. 1 motor 4, which is fixedly installed in the middle of the left side of the front surface of the sand screening box body 1. The other end of the output shaft of the No. 1 motor 4 is fixedly sleeved with a No. 1 round shaft 5, and the outer surface of the No. 1 round shaft 5 is fixedly sleeved with a rotating rod 6, and the other end of the rotating rod 6 is hinged with a connecting rod 7, and the other end of the connecting rod 7 is hinged with a moving plate 8. The outer surface of the moving plate 8 is movably connected to the inner surface of the sliding groove 3 and the upper surface of the sand screening box body 1, and the rear side of the upper surface of the moving plate 8 is fixedly connected with a feeding port 9. The rotation of the rotating rod 6 causes the connecting rod 7 to drive the moving plate 8 as a whole to move left and right.
[0033] When the No. 1 motor 4 starts to run, the rotating rod 6 will start to rotate, which will cause the connecting rod 7 to start to rotate with the other end of the rotating rod 6 as the axis. At the same time, the other end of the connecting rod 7 will drive the moving plate 8 as a whole, so that the moving plate 8 as a whole starts to move left and right under the limit of the sliding groove 3.
[0034] Among them, an installation shaft 11 is movably connected to the middle part of the right side of the outer surface of the sand screening box body 1, the rear end of the installation shaft 11 penetrates the sand screening box body 1 and extends to the rear side of the sand screening box body 1, and the top of the inner surface of the rear side of the sand screening box body 1 is movably connected to a splint 10 located under the movable plate 8, and the upper surface of the splint 10 and the lower surface of the movable plate 8 are fixedly connected.
[0035] The design of the clamping plate 10 limits the movement of the entire movable plate 8, thereby ensuring the stability of the entire movable plate 8 when it moves left and right.
[0036] The outer surface of the installation shaft 11 is fixedly sleeved with a hollow plate 12 located inside the sand screening box 1 , and the inner surface of the hollow plate 12 is fixedly installed with a screen 13 .
[0037] When the hollow plate 12 starts to rotate and swing slightly with the installation shaft 11 as the axis, the screen 13 will screen the sand.
[0038] Among them, a No. 2 motor 14 is fixedly installed on the left side of the outer surface of the sand screening box body 1, a No. 2 circular shaft 15 is fixedly sleeved on the other end of the output shaft of the No. 2 motor 14, and a gear 16 is fixedly sleeved on the outer surface of the No. 2 circular shaft 15.
[0039] When the second motor 14 is running, the second circular shaft 15 will drive the gear 16 to start rotating.
[0040] Among them, the outer surface of the gear 16 is meshed with a tooth plate 17, and the left side of the rear surface of the tooth plate 17 is fixedly connected with a sand retaining plate 18. The right end of the sand retaining plate 18 passes through the sand screening box body 1 and extends to the interior of the sand screening box body 1 and is fixedly connected with a fixed push block 19.
[0041] Since the outer surfaces of the gear 16 and the toothed plate 17 are meshed, the rotation of the gear 16 drives the toothed plate 17 , so that the toothed plate 17 and the sand retaining plate 18 as a whole begin to move rightward under the limit of the sand screening box body 1 .
[0042] Among them, the bottom end of the inner surface of the fixed push block 19 is movably connected to a movable push block 20, and the left and right sides of the upper surface of the movable push block 20 are fixedly connected to springs 21, and the top end of the spring 21 is fixedly connected to the top of the inner surface of the fixed push block 19.
[0043] When the hollow plate 12 swings as a whole, the movable push block 20 will always contact the upper surface of the screen 13 due to the design of the spring 21 .
[0044] Among them, the lower side of the outer surface of the sand screening box body 1 is movably connected with a fine sand box 27 located below the hollow plate 12, and the rear end of the fine sand box 27 penetrates the sand screening box body 1 and extends to the interior of the sand screening box body 1; the left surface of the sliding block 2 is movably connected with a coarse sand box 28, and the outer surface of the coarse sand box 28 is movably connected to the inner surface of the sand screening box body 1; a pneumatic cylinder 22 is fixedly installed on the left side of the upper surface of the sand screening box body 1, and the bottom end of the pneumatic cylinder 22 penetrates the sand screening box body 1 and extends to the interior of the sand screening box body 1 and is fixedly connected with a leakage-proof plate 23, and the lower surface of the leakage-proof plate 23 is movably connected to the upper surface of the sliding block 2.
[0045] Due to the design of the anti-leakage plate 23 , it is ensured that the sand material put into the sand screening box body 1 will not directly slide from the upper surface of the sliding block 2 into the coarse sand box 28 .
[0046] Among them, a No. 3 motor 24 is fixedly installed inside the sliding block 2, and a No. 3 circular shaft 25 is fixedly sleeved on the other end of the output shaft of the No. 3 motor 24. A cam 26 located below the hollow plate 12 is fixedly sleeved on the outer surface of the No. 3 circular shaft 25, and the outer surface of the top end of the cam 26 is movably connected to the right side of the lower surface of the hollow plate 12.
[0047] When the third motor 24 starts to run, the third circular shaft 25 drives the cam 26 to start rotating. Due to the shape design of the cam 26, the rotation of the cam 26 causes the entire hollow plate 12 to start rotating and swinging around the mounting shaft 11 as the axis.
[0048] The working principle and use process of this utility model:
[0049] First, the operator places the sand above the feed port 9 and then starts the No. 1 motor 4. The operation of the No. 1 motor 4 will cause the rotating rod 6 to start rotating. At this time, the connecting rod 7 will start to rotate with the other end of the rotating rod 6 as the axis, and the other end of the connecting rod 7 will drive the movable plate 8 as a whole and make the movable plate 8 as a whole start to move left and right under the limit of the sliding groove 3, so that the sand is evenly distributed above the screen 13. Then the operator starts the No. 3 motor 24. The operation of the No. 3 motor 24 will cause the No. 3 circular shaft 25 and the cam 26 to start rotating, and the rotation of the cam 26 will push the lower surface of the hollow plate 12, so that the hollow plate 12 as a whole starts to rotate and swing with the mounting shaft 11 as the axis, which makes the screen 13 screen the sand above the screen 13, and the sand of appropriate coarseness and fineness will fall into the fine sand box 27 through the screen 13, while the coarser sand will accumulate on the upper surface of the screen 13.
[0050] Then, the operator starts the pneumatic cylinder 22, and the operation of the pneumatic cylinder 22 will cause the leak-proof plate 23 to move upward, so that the leak-proof plate 23 releases the obstruction to the sand. Then the operator starts the No. 2 motor 14, and the operation of the No. 2 motor 14 will cause the No. 2 circular shaft 15 to drive the gear 16 to start rotating, and the toothed plate 17 as a whole will start to move to the right under the meshing drive of the gear 16. In this process, the fixed push block 19 and the movable push block 20 will push the coarse sand on the upper surface of the screen 13 to move to the right together, and finally the coarse sand will be pushed into the upper surface of the sliding block 2 and slide into the interior of the coarse sand box 28, so that the screen 13 is no longer blocked by the coarse sand, thereby ensuring the normal screening function of the hollow plate 12 as a whole for the sand.
[0051] The above are only preferred embodiments of the present invention and are not intended to limit the present invention. Any modifications, equivalent substitutions, improvements, etc. made within the spirit and principles of the present invention should be included in the protection scope of the present invention.
