When the sand box is in a silent state or a compaction state, the second magnet 18 and the first magnet 19 are attracted through magnetic force, and further, the bottom plate 9 is ensured to be horizontal in the silent state through the magnetic attraction guidance of the two magnets, and the bottom plate 9 is ensured not to have a gap opening between the sand box main body 1, so that the smooth implementation of compaction work is ensured, and the quality of finished products is improved.
As an embodiment of the present invention, as shown in fig. 8, the filter screen 13 is designed to have an arc-shaped structure, the upper end surface of the filter screen 13 is uniformly distributed and fixed with the sand crushing blocks 14 at equal intervals, the length of the sand crushing block 14 located in the middle of the lower end surface of the bottom plate 9 decreases gradually towards two sides in sequence, a gap of 8 to 15cm is reserved between the bottom end of the sand crushing block 14 and the filter screen 13, and the rotation angle of the bottom plate 9 through the rotating shaft 12 ranges from 0 to 25 °.
At the sediment outflow in-process, the grit that drops and collect the chamber passes through filter screen 13 and filters, tiny grit gets into collecting box 7, the grit that the nodulation becomes the piece drops on filter screen 13, at the sediment outflow in-process, bottom plate 9 takes place the slope, when producing the horizontal hunting, drive the broken sand piece 14 motion that is located bottom plate 9 below, broken sand piece 14 will remain the sand piece on filter screen 13 and hit the bits of broken glass, hit tiny grit rethread filter screen 13 that the back formed after the bits of broken glass and fall to collecting box 7 in, whole sediment outflow process is accomplished the back again, pull out collecting box 7 through handle 8, accomplish the recovery and recycle to the grit, the benefit of retrieving is greatly improved, and the production cost is reduced.
The working principle is as follows:
when the sand box main body 1 is used, the sand and stone inside the sand box main body 1 need to be compacted and scraped, after the sand and stone are filled in the sand box main body 1, the pressure plate 3 and the limiting block 4 penetrate through two sides of the first notch 20 and the second notch 22 respectively to be matched with each other, so that the pressure plate, the movable block 6 and the bottom plate 9 are matched with each other to form a sealed space, the two movable plates 2 are driven to move oppositely through the output end of the air cylinder 10, the rolling ball 17 rolls in the rolling groove 5 on the inclined plane of the limiting block 4 in the process that the movable plates 2 move oppositely, meanwhile, the limiting block 4 is driven to extrude the pressure plate 3 to generate downward extrusion force on the movable block 6 because the left inclined plane and the right inclined plane of the limiting block 4 are in a splayed structure, the spring 11 is deformed by the downward pressure of the movable block 6, the movable block 6 moves downward in the cavity 21 to compress the spring 11, and the sand and stone on the bottom plate 9 in the sand box main body 1 are subjected to left side and right side and upper side forces, thereby playing the role of compaction and strickling. When the pouring work is finished, the gravels need to be discharged, the output end of the air cylinder 10 drives the two movable plates 2 to move oppositely, when the second balls 16 at the bottoms of the movable plates 2 enter the second S-shaped rolling groove 15 formed in the upper surface of the rotating shaft 12, the rotating shaft 12 is forced to carry the bottom plate 9 to swing left and right through rolling displacement in the second S-shaped rolling groove 15, the bottom plate 9 tilts and vibrates, the opening of the side wall of the sand box main body 1 and the opening of the bottom plate 9 are opened at the moment, the gravels remained on the bottom plate 9 enter the collecting box 7 through the filter screen 13, the broken sand block 14 at the lower end of the bottom plate 9 is driven to move while the bottom plate 9 swings left and right, the broken sand block 14 can break the sand remained on the filter screen 13, the broken sand passes through the filter screen 13 and enters the collecting box 7, and after the sand discharge is finished, the collecting box 7 is taken out through the handle 8 to recycle the gravels for recycling.
Finally, it should be noted that: the above embodiments are only used to illustrate the technical solution of the present invention, and not to limit the same; while the invention has been described in detail and with reference to the foregoing embodiments, it will be understood by those skilled in the art that: the technical solutions described in the foregoing embodiments may still be modified, or some or all of the technical features may be equivalently replaced; and the modifications or the substitutions do not make the essence of the corresponding technical solutions depart from the scope of the technical solutions of the embodiments of the present invention.
