Technical Field
[0001] The utility model relates to the technical field of construction tools, in particular to a sand screening device for construction. Background Art
[0002] In the field of construction engineering, sand, as an indispensable raw material for concrete, plays an irreplaceable role. In order to control the quality of concrete, the sand needs to be screened to ensure that the particle size of the sand is within the standard range. At present, a special sand screening device is needed when screening sand. The traditional sand screening device manually scoops up the sand and throws it onto the screen. Then, under the action of the sand's own gravity, unqualified stones or debris in the sand are screened out. However, this method is relatively inefficient and puts a heavy burden on the workers.
[0003] To this end, the present application designs a sand screening device for construction to solve the above problems. Summary of the Invention
[0004] In order to make up for the deficiencies in the prior art, the utility model provides a sand screening device for construction.

[0006] The base sand box is a rectangular box with an open top, and four legs are installed at the four corners of the bottom. The legs on one side are higher than the legs on the other side, so that the base sand box is tilted as a whole. A bracket is installed on the base sand box, and a rolling screen is rotatably connected to the bracket. Sand is put into the rolling screen, and the small-particle sand is sifted into the base sand box at the bottom by the rolling of the rolling screen.
[0007] Furthermore, in order to better realize the present invention, a unloading door is hinged on the lower side of the base sand box, and a sliding seat is installed above the higher side. A sliding rod is slidably connected in the sliding seat, and one end of the sliding rod is fixedly connected to a push plate. The push plate is erected in the base sand box and is close to the bottom surface of the base sand box.
[0008] Furthermore, in order to better implement the present invention, rollers are installed at the bottom of the legs.
[0009] Furthermore, in order to better realize the present invention, a slot is provided on the bracket, and a stone receiving plate is detachably inserted into the slot, and the stone receiving plate is located below the rolling screen.
[0010] Furthermore, in order to better realize the present invention, the roller of the rolling screen is connected to a rocker, the arc surface of the rolling screen is provided with sieve holes, and a feed door is hinged on the arc surface.
[0011] The beneficial effects of the utility model are:
[0012] The device of the utility model can reduce the workload of manual sand screening. Fine sand is screened into the sand box of the base at the bottom by shaking and rotating the rolling screen, and the remaining large-grained sand and gravel in the rolling screen can fall into the stone receiving plate.

[0019] The following will be combined with the accompanying drawings of the embodiments of the present invention to clearly and completely describe the technical solutions of the embodiments of the present invention. Obviously, the embodiments described are only some of the embodiments of the present invention, not all of them. Generally, the components of the embodiments of the present invention described and shown in the drawings herein can be arranged and designed in a variety of different configurations.
[0020] Therefore, the following detailed description of the embodiments of the present invention provided in the accompanying drawings is not intended to limit the scope of the claimed invention, but merely represents selected embodiments of the present invention. All other embodiments obtained by those skilled in the art based on the embodiments of the present invention without creative work are within the scope of protection of the present invention.
[0021] Figure 1-Figure 4This is a specific embodiment of the utility model, which is a sand screening device for construction. This embodiment is a sand screening device for construction. The base sand box 1 is a rectangular box with an open top, and four legs 101 are installed at the four corners of the bottom. The legs 101 on one side are higher than the legs 101 on the other side, so that the base sand box 1 is tilted as a whole. A bracket 2 is installed on the base sand box 1, and a rolling screen 3 is rotatably connected to the bracket 2. Sand is put into the rolling screen 3, and the small-particle sand is screened into the base sand box 1 at the bottom through the rolling of the rolling screen 3.
[0022] like Figure 2 As shown, a discharge door 103 is hingedly connected to the lower side of the base sand box 1, and a slide 104 is installed above the upper side. A slide rod 105 is slidably connected to the slide 104. One end of the slide rod 105 is fixedly connected to a push plate 106. The push plate 106 stands upright in the base sand box 1 and abuts against the inner bottom surface of the base sand box 1. Rollers 102 are installed at the bottom of the support legs 101.
[0023] like Figure 3 Figure 4 As shown, the bracket 2 is provided with a slot 201, in which a stone receiving plate 202 is detachably inserted, and the stone receiving plate 202 is located below the roller screen 3. The roller of the roller screen 3 is connected to a rocker 301, and the arc surface of the roller screen 3 is provided with a sieve hole 302, and a feed door 303 is hinged on the arc surface.
[0024] The specific usage of this embodiment is as follows:
[0025] This device can be moved as a whole to any position on the construction site. The worker opens the feed door 303 and pours sand into the rolling screen 3. Then, he closes the feed door 303 and inserts the latch. He turns the rocker 301 to drive the rolling screen 3 to rotate, so that the fine sand is screened into the base sand box 1 at the bottom. After the sand screening is completed, the stone receiving plate 202 is inserted into the bracket 2, and the feed door 303 is opened to pour the remaining coarse sand and gravel into the stone receiving plate 202 and slide it to the ground. Then, the stone receiving plate 202 is removed and new sand is poured into the rolling screen 3 to continue screening. After the sand screening is completed, the unloading door 103 can be opened to pour out the fine sand, and pushing the slide bar 105 can make the push plate 106 assist in unloading.
