[0002] Construction engineering refers to the engineering entity formed by the construction of various buildings and their ancillary facilities and the installation of supporting lines, pipelines and equipment. Sand and gravel are commonly used materials in construction engineering. During construction, construction workers use sand and gravel screening devices for construction engineering to screen sand and gravel of different sizes.

[0003] In existing construction engineering sand and gravel screening equipment, in order to obtain sand and gravel of a specific size, personnel use filter screens with filter holes of the corresponding diameter. However, when replacing the filter screen, the replacement process is cumbersome and time-consuming, resulting in a long downtime and thus reducing the efficiency of sand and gravel processing. Utility Model Content

[0004] The technical problem that this utility model aims to solve in view of the above-mentioned prior art is that the replacement of the filter screen in existing sand and gravel screening devices for construction projects is cumbersome and time-consuming, resulting in a long downtime.

[0005] To solve the above problems, this utility model provides a sand and gravel screening device for construction engineering, including a processing box, a support frame movably inserted inside the processing box, a support frame fixedly connected to a pair of side ends of the processing box, a pair of filter plates placed against the upper end of one of the support frames, a collection box movably inserted inside the processing box, a fixing pipe fixedly connected to the upper end of the support frame, a pair of insertion slots opened at the outer end of the fixing pipe, an insertion pipe movably inserted inside the insertion slot, a spring fixedly connected between the insertion pipe and the insertion slot, and a reinforcing groove opened on the side end of the filter plate for movably inserting into the insertion pipe.

[0006] In the above-mentioned sand and gravel screening device for construction engineering, the operation steps for replacing the filter mechanism are simple and the time required for replacing the filter mechanism is reduced, thereby improving the efficiency of sand and gravel processing.

[0007] As a further improvement of this application, the number of filter plates is three, and in the initial state, one of the filter plates is movably inserted inside the support frame.

[0008] As a further improvement of this application, multiple limiting tubes are movably inserted inside the processing box, and multiple docking grooves are opened on the inner wall of the processing box to movably insert the limiting tubes. The lower end of the limiting tube movably passes through the support frame and the filter plate and is inserted inside the docking groove.

[0009] As a further improvement of this application, the upper end of the processing box is fixedly connected to a feed pipe, and the outer end of the feed pipe is threaded with a sealing cap.

[0010] As a further improvement of this application, the two insertion tubes are internally fixedly connected to the same vertical tube, and the upper end of the support frame is provided with a sliding groove that is slidably connected to the vertical tube, and the lower end of the vertical tube is inserted into the sliding groove.

[0011] As a further improvement of this application, a sleeve ring is fixedly connected to the upper end of the vertical pipe, and a rubber ring is fixedly connected to the outer end of the sleeve ring.

[0012] As another improvement of this application, a water tank is fixedly connected to the side of the processing box, and a spray pump is installed inside the water tank. A nozzle is fixedly connected to the water outlet of the spray pump. The nozzle is inserted inside the processing box and located above the collection box. A base is fixedly connected to the bottom of the processing box. A pull-out plate is movably inserted inside the base. Discharge holes are opened on both the pull-out plate and the inner bottom wall of the collection box.

[0013] In summary, when using this application, the appropriate filter plate is selected according to the required size of sand and gravel. Since the two adjacent filter plates are connected by a hinge, the filter plate can be flipped or directly pushed into the support frame when installing or replacing it. Then, the filter plate is fixed in the support frame by the limiting tube. Subsequently, the sand and gravel can be filtered using the filter plate. Therefore, the operation steps of this device are simple when replacing the filter mechanism, and the time required for replacing the filter mechanism is reduced, thereby improving the efficiency of sand and gravel processing.

[0021] The two embodiments of this application will be described in detail below with reference to the accompanying drawings.

[0022] First implementation method:

[0023] Figure 1-4 A sand and gravel screening device for construction engineering is shown, including a processing box 1, a support frame 2 is movably inserted inside the processing box 1, a support frame 3 is fixedly connected to a pair of side ends of the processing box 1, a pair of filter plates 4 are placed against the upper end of one of the support frames 3, the filter plates 4 are equipped with a vibrating motor, a collection box 5 is movably inserted inside the processing box 1, a fixing pipe 6 is fixedly connected to the upper end of the support frame 3, a pair of insertion slots are opened at the outer end of the fixing pipe 6, an insertion pipe 7 is movably inserted inside the insertion slot, a spring 8 is fixedly connected between the insertion pipe 7 and the insertion slot, and a reinforcing groove 9 is opened at the side end of the filter plate 4 and is movably inserted into the insertion pipe 7.

[0024] There are three filter plates 4, and the filter holes on the three filter plates 4 are of different sizes. The connection between two adjacent filter plates 4 is hinged. In the initial state, one of the filter plates 4 is movably inserted into the support frame 2. Multiple limiting tubes 10 are movably inserted into the processing box 1. Multiple docking grooves 11 are opened on the inner wall of the processing box 1, which are movably inserted into the limiting tubes 10. The lower end of the limiting tube 10 movably passes through the support frame 2 and the filter plate 4 and is inserted into the docking groove 11. The upper end of the processing box 1 is fixedly connected to the feed pipe 12. The outer end of the feed pipe 12 is threaded with a sealing cap. The interior of a pair of insertion pipes 7 is fixedly connected to the same vertical pipe 13. The upper end of the support frame 3 is opened with a sliding groove 14 that is slidably connected to the vertical pipe 13. The lower end of the vertical pipe 13 is inserted into the sliding groove 14. The upper end of the vertical pipe 13 is fixedly connected to a sleeve ring. The outer end of the sleeve ring is fixedly connected to a rubber ring.

[0025] The use of this application involves the following steps:

[0026] Step 1: When using the equipment, feed sand and gravel into the processing box 1 through the feed pipe 12, so that it falls onto the filter plate 4 inside the support frame 2. After feeding, seal the feed pipe 12 with the sealing cover to prevent dust from drifting out of the processing box 1. Then, start the vibration motor inside the filter plate 4 to make the filter plate 4 vibrate to screen and filter the sand and gravel. Some of the sand and gravel will remain on the filter plate 4, and the other part of the sand and gravel will pass through the filter plate 4 and fall into the collection box 5. After filtration is completed, remove the filter plate 4, the support frame 2, and the collection box 5 from the processing box 1. Finally, remove the sand and gravel from the support frame 2 and the collection box 5 for use.

[0027] Step 2: When other sizes of sand and gravel are needed, simply select a filter plate 4 that corresponds to the size of the sand and gravel. Then, remove the limiting tube 10 from the processing box 1 to release the limiting effect on the support frame 2. Then, flip or directly push the filter plate 4 outside the processing box 1 to apply force to push the filter plate 4 inside the support frame 2 to the outside of the processing box 1. Push the selected filter plate 4 into the support frame 2 to filter the sand and gravel. Finally, reset the limiting tube 10 and fix the support frame 2.

[0028] In summary, when using this application, the appropriate filter plate 4 is selected according to the required size of sand and gravel. Since two adjacent filter plates 4 are connected by a hinge, the filter plate 4 can be flipped or directly pushed into the support frame 2 when installing or replacing it. Then, the filter plate 4 is fixed in the support frame 2 by the limiting tube 10. Subsequently, the sand and gravel can be filtered using the filter plate 4. Therefore, the operation steps of this device are simple when replacing the filter mechanism, and the time required for replacing the filter mechanism is reduced, thereby improving the efficiency of sand and gravel processing.

[0029] Second implementation method:

[0030] This embodiment adds the following structure based on the first embodiment, while the rest remains the same as the first embodiment, as detailed below:

[0031] Figure 4-5 A water tank 16 is fixedly connected to the side of the processing box 1. A spray pump is installed inside the water tank 16. A nozzle is fixedly connected to the water outlet of the spray pump. The nozzle is inserted inside the processing box 1 and located above the collection box 5. A base 17 is fixedly connected to the bottom of the processing box 1. A pull-out plate 18 is movably inserted inside the base 17. Both the pull-out plate 18 and the inner bottom wall of the collection box 5 have discharge holes 15.

[0032] When screening sand and gravel, a spray pump can be started to spray water from water tank 16 into the processing box 1, thereby reducing dust from the sand and gravel and lowering the pollution level of the air. Afterward, the wastewater will fall into the collection box 5, then pass through the collection box 5 and the pull plate 18 in sequence, and fall to the bottom of the base 17. The discharge hole 15 on the pull plate 18 can filter the sand and gravel in the water, reducing the amount of sand and gravel wasted. Finally, the pull plate 18 is removed from the base 17, the sand and gravel debris on it is cleaned, and the wastewater in the base 17 is taken out and purified for recycling.

[0033] In light of current practical needs, the above-described embodiments adopted in this application are not limited to these. Any changes made within the scope of knowledge possessed by those skilled in the art without departing from the concept of this application still fall within the protection scope of this utility model.
