[0022] In the present utility model, by setting the fixing frame 1 and the filtering cylinder 2, the filtering cylinder 2 is inclinedly installed on the fixing frame 1. The coarse sieve assembly can filter and separate large-particle sand and gravel. The coarse sieve mesh is composed of a plurality of parallel connecting rods 4. The distance between adjacent two connecting rods 4 is the same. The distance adjusting assembly can adjust the distance between the connecting rods 4 and can filter out sand and gravel of different sizes. The fixed-distance equalizing plates 5 are fixedly connected to the connecting frame 3. There are two fixed-distance equalizing plates 5. A plurality of sliding tracks 6 are opened on the fixed-distance equalizing plates 5. The horizontal distance between adjacent two sliding tracks 6 is the same at each position, so that the distance between adjacent connecting rods 4 is kept the same. The two ends of the connecting rods 4 are slidably connected inside the sliding tracks 6, which can facilitate the guiding of the adjustment of the distance between the connecting rods 4. The limiting plate 7 is horizontally arranged. There is a long groove inside the limiting plate 7. The connecting rods 4 can move inside the long groove, which can keep the plurality of connecting rods 4 at the same height.

[0023] Further, the lifting assembly includes a lead screw 8 rotatably connected to one side of the equidistant equalizing plate 5. Slider one 9 and slider two 10 are respectively installed at both ends of the limiting plate 7. Slider one 9 is screwed to the lead screw 8. A chute 11 is formed on the equidistant equalizing plate 5. Slider two 10 is slidably connected to the chute 11. By providing the lead screw 8, the lead screw 8 is rotatably connected to the outside of the equidistant equalizing plate 5. Slider one 9 and slider two 10 are installed at both ends of the limiting plate 7. Rotation of the lead screw 8 can drive the limiting plate 7 to lift through slider one 9. Lifting of the limiting plate 7 can drive multiple connecting rods 4 to lift synchronously. The chute 11 is formed on the equidistant equalizing plate 5. Lifting of the limiting plate 7 can lift along the chute 11, which can position the lifting of the limiting plate 7 and multiple connecting rods 4.

[0024] Further, a guide rod 16 is provided on the equidistant equalizing plate 5. Slider two 10 is slidably connected to the guide rod 16. By providing the guide rod 16, the guide rod 16 is slidably connected to slider two 10, which can further guide the movement of the limiting plate 7 and the equidistant equalizing plate 5, facilitating the lifting of multiple connecting rods 4.

[0025] Further, a gear 12 is connected to the top of the lead screw 8. A worm 13 cooperating with the gear 12 is installed on the connecting frame 3. The worm 13 is in transmission connection with the gear 12. By providing the gear 12, the gear 12 is fixedly connected to the top of the lead screw 8. The worm 13 is located on one side of the gear 12. Rotation of the worm 13 can drive the lead screw 8 to rotate through the gear 12. Rotation of the lead screw 8 can drive the coarse screen to lift through slider one 9, facilitating the adjustment of the height of the connecting rod 4.

[0026] Further, a guide plate 14 is installed in the middle and lower part of the coarse screen in an inclined manner. A collection basket 15 is installed below the coarse screen. By providing the guide plate 14, the guide plate 14 is installed in the middle and lower part of the coarse screen, which can export larger materials, facilitating the filtration and separation of sand and gravel. The collection basket 15 is located below the coarse screen, which can collect the large - particle sand and gravel exported by the guide plate 14.

[0027] Further, a receiving plate 17 is provided below the coarse screen. The bottom of the receiving plate 17 is inclined towards the feeding end of the filter cylinder 2. By providing the receiving plate 17, the receiving plate 17 is located below the coarse screen. Small - particle sand and gravel screened by the coarse screen can enter the receiving plate 17 through the gaps between the connecting rods 4. The inclined receiving plate 17 can facilitate the transportation of sand and gravel into the filter cylinder 2.

[0028] Further, two converging plates one 18 are installed in the middle and upper part of the coarse screen, and two converging plates two 19 are installed at the bottom of the coarse screen. By providing the converging plates one 18 and the converging plates two 19, the converging plates one 18 can facilitate the entry of materials onto the coarse screen for separation. The converging plates two 19 are located on both sides of the receiving plate 17, which can reduce the loss of sand and gravel after screening.

[0029] Before use, adjust the distance between the connecting rods 4 according to the size of the sand and gravel to be filtered. During the adjustment process, first drive the gear 12 to rotate through the worm 13. The gear 12 can drive the lead screw 8 to rotate. The rotation of the lead screw 8 can drive the limiting plate 7 to rise and fall through the slider one 9. The limiting plate 7 can drive multiple connecting rods 4 to rise and fall synchronously. Since the connecting rods 4 rise and fall along the sliding track 6 and the distance between adjacent sliding tracks 6 remains the same, the adjacent connecting rods 4 can remain the same. After the adjustment is completed, put the sand and gravel to be filtered on the top of the coarse screen at a certain rate. The sand and gravel enter the coarse screen under the guidance of the gathering plate one 18. Since the coarse screen is inclined, the sand and gravel will move on the coarse screen due to its own gravity. During the movement, the sand and gravel with smaller particles will fall from the gaps between the connecting rods 4, and the sand and gravel with larger particles will flow above the coarse screen. When it touches the guide plate 14, the sand and gravel will move out of the coarse screen under the action of the guide plate 14 and fall into the collection basket 15 at the bottom. The sand and gravel with smaller particles will enter the receiving plate 17 after falling from the coarse screen. The bottom end of the receiving plate 17 extends to the inside of the filter cylinder 2. Subsequently, the material enters the filter cylinder 2 for filtration and separation, and the filtered sand and gravel will be exported from the bottom of the filter cylinder 2.

Any person skilled in the art within the technical scope disclosed by the present invention, according to the technical solution of the present invention and its inventive concept, makes equivalent substitutions or changes, and should be covered by the protection scope of the present invention.
