Description

Technical Field

[0001] The utility model belongs to the technical field of building construction, in particular to a sand screening device for house construction. Background Art

[0002] Sand screening for house construction is a process of screening and filtering sand during house construction in order to remove impurities, stones, soil and other unnecessary substances in the sand, thereby improving the quality of the building.

[0003] However, the existing sand screening device for house construction still has disadvantages in actual use: when the operator pours the sand to be screened on the top of the screen plate, if the amount of sand poured is large, local accumulation will appear on the top surface of the screen plate, thereby affecting the screening effect of the sand. At this time, the sand can only be screened normally after the operator moves the accumulated sand area to disperse it. This process is time-consuming and labor-intensive, and greatly reduces the overall work efficiency, so it needs to be improved. Utility Model Content

Through the cooperation of structures such as a toggle plate and a gear shaft, when the screen plate moves upward, it will drive the L-shaped plate rack to engage with the gear shaft, drive the gear shaft to rotate, and force one end of the chain to reel in on its surface, and the other end of the chain will drive the toggle plate to move toward one side of the second spring telescopic cylinder, and the bottom end of the toggle plate will be toggled on the top surface, so as to break up the locally accumulated sand and avoid sand accumulation, thereby improving the sand screening efficiency.

[0005] To achieve the above-mentioned purpose, the utility model provides the following technical solutions: a sand screening device for house construction, comprising a sand screening bin, the interior of which is slidably connected with a screening member, the top of which is connected with a movable component slidably connected with the upper end of the inner cavity of the sand screening bin, and a moving component connected with the screening member is installed on one side of the movable component;

[0024] The following will be combined with the drawings in 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 in 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.

[0025] like Figures 1 to 8 As shown, the utility model provides a sand screening device for house construction, comprising a sand screening bin 1, a screening member 7 is slidably connected to the interior of the sand screening bin 1, a movable component 3 slidably connected to the upper end of the inner cavity of the sand screening bin 1 is connected to the top of the screening member 7, and a moving component 4 connected to the screening member 7 is installed on one side of the movable component 3;

[0026] The movable component 3 includes two toggle plates 31, the moving component 4 includes a chain 41 connected to the toggle plate 31, and the end of the chain 41 away from the toggle plate 31 is wound with a gear shaft 42 connected to the bearing of the sand screening bin 1, and the screening member 7 includes a sieve plate 71, and L-shaped plates 72 are fixedly installed on both sides of the sieve plate 71. The upper end of the L-shaped plate 72 close to the side wall of the sieve plate 71 is meshed and connected with the gear shaft 42.

[0027] like Figure 1 , Figure 2 and Figure 8As shown, a collecting box 2 is placed below the sand screening bin 1, and the lower end of the sand screening bin 1 is in an inverted trapezoidal shape. Gears are installed on both sides of the outer wall of the gear shaft 42, and no gears are provided on the outer wall of the middle end of the gear shaft 42. The outer wall is wound with the chain 41, and the gears on both sides of the outer wall of the gear shaft 42 are meshed and connected with the L-shaped plate 72.

[0028] The above scheme is adopted: the inverted ladder-shaped appearance of the sand screening bin 1 facilitates the discharge of internal sand, so that the sand can fall into the interior of the collecting box 2 more accurately. When the L-shaped plate 72 moves upward, it drives the gears on both sides of the outer wall of the gear shaft 42 to rotate synchronously, thereby driving the outer wall of the middle end of the gear shaft 42 to drive one end of the chain 41 to roll up on the outer wall of the middle end of the gear shaft 42.

[0029] like Figure 5 As shown, the toggle plate 31 is elastically connected to the sand screening bin 1 through the first spring telescopic cylinder 32, and hollow partitions are installed on both sides of the bottom end of the toggle plate 31, and the partitions are movably connected to the top surface of the screen plate 71.

[0030] By adopting the above solution, the partition at the bottom of the shifting plate 31 will shift the sand on the top surface of the sieve plate 71 to avoid the phenomenon of local sand accumulation on the top surface of the sieve plate 71 after the sand on the top surface of the sieve plate 71 is poured in.

[0031] like Figure 2 and 7 As shown, a belt drive module 5 is installed on the back of the sand screening bin 1, and a rotating rod 6 connected to the inner cavity bearing of the sand screening bin 1 is installed at the output end of the belt drive module 5. A triangular block is installed on the outside of the rotating rod 6, and the outer wall of the triangular block is in contact with the bottom surface of the screen plate 71.

[0032] The above scheme is adopted: when the belt drive module 5 is running, it drives the rotating rod 6 and the triangular block installed on its outer wall to rotate in the same direction. When the triangular block rotates in the same direction, it will drive the screen plate 71 inside the sand screening bin 1 to vibrate, so as to filter and screen the sand.

[0033] like Figure 6 and Figure 8 As shown, a folding plate 8 is installed on the top surface of the L-shaped plate 72 close to one end of the screen plate 71 , and the top end of the folding plate 8 is located below the chain 41 and is fixedly connected to the sand screening bin 1 .

[0034] The above solution is adopted: through the design of the folding plate 8, when the sieve plate 71 moves upward inside the sand screening bin 1, the folding plate 8 will be compressed synchronously, and conversely, when the sieve plate 71 moves downward, the folding plate 8 will stretch, and the folding plate 8 effectively prevents the sand on the top surface of the sieve plate 71 from entering the sand screening bin 1.

[0035] like Figure 8As shown, the L-shaped plate 72 is elastically connected to the sand screening bin 1 through a second spring telescopic cylinder 73 , and two sets of racks are provided on a side wall of the upper end of the L-shaped plate 72 opposite to the gear shaft 42 , and both are meshed and connected with the gear shaft 42 .

[0036] The working principle and use process of this utility model:

[0037] First, the operator pours sand from the top of the sand screening bin 1 onto the top surface of the screen plate 71, and starts the belt drive module 5. The operation of the belt drive module 5 will drive the rotating rod 6 to rotate in the same direction. When the rotating rod 6 rotates, it will synchronously contact the screen plate 71 to make the screen plate 71 vibrate, thereby achieving sand screening;

[0038] Secondly, when the sieve plate 71 moves upward, it will drive the L-shaped plate 72 to move in the same direction. The rack at the upper end of the L-shaped plate 72 meshes with the gear shaft 42, driving the gear shaft 42 to rotate. At this time, the gear shaft 42 will cause one end of the chain 41 to roll up on its surface, and the end of the chain 41 away from the gear shaft 42 will drive the toggle plate 31 to move toward the side of the second spring telescopic cylinder 73. During the movement, the bottom end of the toggle plate 31 will be toggled on the top surface of the sieve plate 71, so as to break up the locally accumulated sand and avoid sand accumulation, thereby improving the sand screening efficiency.
