[0025] By adopting the above technical solution, when sand and gravel need to be screened during the construction process, the sand and gravel are fed into the processing box 1 through the feed hopper 2, and at the same time, the vibrating screening device 7 works so that the screen plate 6 continuously vibrates to screen the sand and gravel. A large amount of dust will be generated during the feeding process. At this time, the water pump 39 can be started to pump water from the hose 34 to the atomizing nozzle 31 on the surface of the regulating plate 33 and spray it out. The atomized water flow treats the dust generated by the feeding, thereby preventing serious pollution to the working environment and protecting human health.

[0026] Specifically, the bottom end of the adjustment plate 33 is mounted on the upper end of the feed hopper 2 via the damping shaft 32 , and a mounting groove is provided inside the adjustment plate 33 corresponding to the hose 34 .

[0027] By adopting the above technical solution, the adjustment plate 33 can be rotated along the damping shaft 32 to adjust its angle during use, so as to achieve the best spray angle, improve the dust treatment quality, and ensure the use effect of the equipment.

[0028] Specifically, the water level indicating device 35 includes a limit block 351, a guide cylinder 352, a scale rod 353 and a float 354, wherein a guide cylinder 352 is provided at the upper end of the interior of the water tank 37, a scale rod 353 is provided inside the guide cylinder 352, a limit block 351 is provided at the upper end of the scale rod 353, and a float 354 is provided at the bottom end of the scale rod 353.

[0029] By adopting the above technical solution, when the water level inside the water tank 37 drops, the position of the float 354 floating on the water surface drops accordingly, and at the same time, the scale rod 353 moves downward along the guide cylinder 352. The staff can judge the remaining water amount at any time according to the descending position of the scale rod 353 in order to add water, thereby ensuring the use effect of the equipment and preventing water shortage.

[0030] When this embodiment is used: when sand and gravel need to be screened during construction, the sand and gravel are fed into the processing box 1 through the feed hopper 2, and at the same time, the vibrating screening device 7 works so that the screen plate 6 continuously vibrates to screen the sand and gravel. A large amount of dust will be generated during the feeding process. At this time, the water pump 39 can be started to pump water from the hose 34 to the atomizing nozzle 31 on the surface of the adjustment plate 33 for spraying. The atomized water flow processes the dust generated by the feeding, preventing serious pollution to the working environment and protecting human health. At the same time, when in use, the adjustment plate 33 can be rotated along the damping shaft 32 to adjust its angle so as to achieve the optimal spray angle, improve the dust treatment quality, and ensure the use effect of the equipment;

[0031] When the water level inside the water tank 37 drops, the position of the float 354 floating on the water surface drops accordingly, and at the same time the scale rod 353 moves downward along the guide cylinder 352. The staff can judge the remaining water amount at any time according to the descending position of the scale rod 353 in order to add water, thereby ensuring the use effect of the equipment and preventing water shortage.

A large amount of dust will be generated during the feeding process. At this time, the water pump 39 can be started to pump water from the hose 34 to the atomizing nozzle 31 on the surface of the adjusting plate 33 for spraying. The atomized water flow processes the dust generated by the feeding, preventing the working environment from being polluted and protecting human health. At the same time, the adjusting plate 33 can be rotated along the damping shaft 32 to adjust its angle during use, so as to achieve the best spray angle, improve the dust treatment quality, and ensure the use effect of the equipment;

[0040] When the water level inside the water tank 37 drops, the position of the float 354 floating on the water surface drops accordingly, and at the same time, the scale rod 353 moves downward along the guide cylinder 352. The staff can judge the remaining water amount at any time according to the descending position of the scale rod 353 so as to add water, thereby ensuring the use effect of the equipment and preventing water shortage.

[0041] When the screened stones need to be processed, the pull rod 41 is pulled upward to make the positioning block 44 move upward along the inside of the guide seat 43. At the same time, the limit spring 42 is compressed. At this time, the stones will push the sealing plate 45 to rotate along the pin shaft 46, and the sealing plate 45 is supported by the support block 47. The fallen stones slide along the surface of the sealing plate 45, ensuring the collection and processing efficiency of the stones and improving the convenience of using the sealing plate 45.
