Based on the embodiments of the present utility model, all other embodiments obtained by those of ordinary skill in the art without creative effort are within the protection scope of the present utility model.

[0022] Please see Figure 1-5 This utility model provides an embodiment of a sand screening device for municipal road construction, comprising a base plate 1, a support 2, spring dampers 3, a vibration structure 4, a screening structure 5, a fixing structure 6, and a collection box 7. The support 2 is fixedly connected to both the front and rear sides of the base plate 1. Two spring dampers 3 are installed on the top of the support 2. Two spring dampers 3 are fixedly connected to both the front and rear sides of the vibration structure 4. The vibration structure 4 is slidably connected to the screening structure 5. Fixing structures 6 are installed at both the front and rear ends of the vibration structure 4 and the screening structure 5. A collection box 7 is installed on the top of the base plate 1. The spring dampers 3 facilitate the absorption of vibrations from the vibration structure 4, preventing the vibrations from affecting the base plate 1 and the support 2, thereby affecting the stability of the equipment.

[0023] The vibration structure 4 includes a slide rail 41, a fixing block 42, a fixing rod 43, a baffle 44, a connecting plate 45, a vibrator 46, and a discharge hopper 47. There are two slide rails 41.

[0024] A fixing block 42 is fixedly connected to the side of the slide rail 41 away from the middle, a fixing rod 43 is fixedly connected to the left side of the two slide rails 41, and a baffle 44 is fixedly connected to the top of the slide rail 41 and the fixing block 42.

[0025] A connecting plate 45 is fixedly connected between the two baffles 44. A vibrator 46 is installed on the top of the connecting plate 45. A discharge hopper 47 is fixedly connected to the left side of the fixed rod 43 and the baffle 44. The gravel is poured onto the top right end of the vibrating structure 4. The vibrator 46 is turned on, causing the vibrator 46 to drive the vibrating structure 4 to vibrate. The vibrating structure 4 drives the screening plate 51 to vibrate. The screening plate 51 vibrates the gravel, thereby screening out the gravel smaller than the holes of the screening plate 51 and letting it fall into the collection box 7. The gravel larger than the holes of the screening plate 51 is discharged from the discharge hopper 47 to the left side, making it convenient for workers to collect.

[0026] The screening structure 5 includes a screening plate 51, a slider 52, a fixed plate 53, and a handle 54. The slider 52 is fixedly connected to both the front and rear sides of the screening plate 51. The slider 52 is slidably connected to the slide rail 41. The fixed plate 53 is fixedly connected to the right side of the screening plate 51 and the slider 52. The handle 54 is fixedly connected to the right side of the fixed plate 53.

[0027] The fixing structure 6 includes a handle 61, a first insertion rod 62, a spring 63, a gasket 64, a second insertion rod 65, and a groove 66. The first insertion rod 62 is fixedly connected to the right side of the handle 61, and one end of the spring 63 is fixedly connected to the right side of the handle 61. The screening plate 51 can be replaced or cleaned through the screening structure 5 and the fixing structure 6, making it convenient to use.

[0028] Insert rod 62 is slidably connected to washer 64, washer 64 is fixedly connected to the other end of spring 63, insert rod 62 is slidably connected to insert rod 65, insert rod 65 has a groove 66, groove 66 engages insert rod 62, press handle 61 to the right, spring 63 is compressed by pressure, causing handle 61 to drive insert rod 62 to move to the right, so that groove 66 no longer engages insert rod 62, pull insert rod 65 upward, so that insert rod 65 no longer fixes the fixing plate 53.

[0029] Working principle:

[0030] In use, the gravel is poured onto the top right end of the vibrating structure 4, and the vibrator 46 is turned on, causing the vibrator 46 to drive the vibrating structure 4 to vibrate. The spring damper 3 helps to absorb the vibration from the vibrating structure 4, preventing the vibration from affecting the base plate 1 and the support 2, thus affecting the stability of the equipment. The vibrating structure 4 drives the screening plate 51 to vibrate, and the screening plate 51 vibrates the gravel, thereby screening out the gravel smaller than the holes of the screening plate 51, which falls into the collection box 7. The gravel larger than the holes of the screening plate 51 is discharged from the discharge hopper 47 to the left. The screen plate 51 is designed for easy collection by staff. When it is necessary to replace the screen plate 51 with a different hole size or to clean the screen plate 51, press the handle 61 to the right. The spring 63 is compressed under pressure, causing the handle 61 to move the first insertion rod 62 to the right. This prevents the groove 66 from engaging the first insertion rod 62. Pull the second insertion rod 65 upward, so that the second insertion rod 65 is no longer fixing the fixing plate 53. Pull the handle 54 to remove the screen plate 51. The screen plate 51 can be replaced or cleaned through the screening structure 5 and the fixing structure 6, making it convenient to use.
