[0022] The following will be combined with the drawings in the embodiments of the utility model to clearly and completely describe the technical solutions in the embodiments of the utility model. Obviously, the described embodiments are only part of the embodiments of the utility model, not all of the embodiments. Based on the embodiments in the utility model, all other embodiments obtained by ordinary technicians in this field without creative work are within the scope of protection of the utility model.

[0023] like Figure 1 as stated;

[0024] A spray dust suppression device for environmental engineering, comprising a dust suppression bottom box 1, a support wheel 11 is installed below the dust suppression bottom box, a recovery funnel 12 is installed above the dust suppression bottom box, and a lifting type rotary projectile spray mechanism 2 is provided above the dust suppression bottom box;

[0025] In the present embodiment, under normal circumstances, when spraying dust suppression is performed on the surrounding environment in the prior art, a fog cannon is often used, which uses wind power to project a large amount of water mist into the air, and then the water mist comes into contact with the dust in the air, so that the dust is dissolved in the water mist, so as to reduce the dust content in the air and achieve the dust suppression effect. However, although this dust suppression method can effectively suppress dust in the environment, it can only spray in a single direction, and the spray range is limited. At the same time, although a large amount of water mist is sprayed, it can suppress dust in the environment, but it causes a large amount of water mist to be wasted; and through the lifting and rotating projectile spraying mechanism 2, rotary spray dust suppression can be performed in multiple directions, and by adjusting the size of the wind force and its rotation speed, the spray range can be adjusted, and the surrounding environment can be quickly dust suppressed.

[0026] like Figure 1-Figure 3 As shown;

[0027] Based on the spray dust suppression method in the prior art, the lifting type rotary projectile spray mechanism 2 can be used to solve the problems of single direction of spray dust suppression and waste of water mist in the prior art.

[0028] More specifically:

[0029] In combination with the above content, in order to avoid the single direction of spray dust suppression and the waste of water mist, a lifting and rotating ejection spray mechanism 2 is provided above the dust suppression bottom box. The lifting and rotating ejection spray mechanism includes a lower support 21, an upper support 22, a wind ejection mechanism 23, an obtuse-angle spray pipe 24, an upper spray pipe 25, a spray nozzle 26, a rotating mechanism 27, a lifting mechanism 28 and a water supply mechanism 29. The upper support is located above the lower support, the wind ejection mechanism is installed between the upper support and the lower support, the wind ejection mechanism is evenly distributed, the obtuse-angle spray pipe is installed above the upper support, the obtuse-angle spray pipe and the wind ejection mechanism are staggered, the obtuse-angle spray pipe is fixedly connected to the upper spray pipe, the upper spray pipe passes through the rotating mechanism and extends out of its lower end, the spray nozzle is installed at the inclined part of the obtuse-angle spray pipe, the spray nozzle is evenly distributed, the rotating mechanism is located below the lower support, the lifting mechanism is located in the dust suppression bottom box, and the water supply mechanism is located in the dust suppression bottom box.

[0030] In this embodiment, the staggered distribution of the wind ejection mechanism 23 and the obtuse-angle spray tube 24 can make the upper support 21 and the lower support 22 rotate at a uniform speed, so that the water mist sprayed by the spray nozzle 26 can be evenly sprayed to the outside world, and then the wind ejection mechanism 23 is used to blow the water mist so that the water mist can be ejected into the environment, so that the spray dust suppression has more directions and can be carried out on multiple positions at the same time. The lifting mechanism 28 can be used to adjust the height of the upper support 21 and the lower support 22, and the spray range of the water mist can be adjusted to ensure that the device can accurately perform spray dust suppression on the surrounding environment. The use of the rotating mechanism can enable the device to evenly eject the water mist into the external environment, thereby effectively suppressing dust in the surrounding environment.

[0031] To be more specific: the rotating mechanism includes a sliding seat 271, a sliding frame 272, a lifting plate 273, a water supply port 274, and a small variable speed motor 275. The sliding seat is installed on the lower surface of the lower support, the sliding frame is installed above the lifting plate, the sliding seat is inserted into the sliding frame, the sliding seat and the sliding frame are connected by a ball sliding connection, the water supply port is opened at the center of the lifting plate, the upper spray pipe passes through the water supply port and extends to the bottom of the lifting plate, the small variable speed motor is installed on the lifting plate, and power is transmitted between the rotating end of the small variable speed motor and the sliding seat through a bevel gear set.

[0032] In this embodiment, the speed of the wind ejection mechanism 23 and the spray nozzle 26 can be controlled by adjusting the speed of the small variable speed motor 275, so that targeted dust suppression work can be carried out on the surrounding environment. When the amount of dust is large, the rotation speed of the small variable speed motor 275 can be controlled to decrease, so that the wind ejection mechanism 23 can be moved slowly to spray a large amount of water mist into the surrounding environment, thereby achieving a rapid dust suppression effect. When the amount of dust is small, the rotation speed of the small variable speed motor 275 can be increased to make the wind ejection mechanism 23 move quickly, thereby reducing the current water mist spraying amount at a single position, but the total spraying amount will not change, and then multiple water mist ejections can be used to reduce the dust content in the air.

[0033] To be more specific: the wind ejection mechanism includes a fan tube 231, a fan bracket 232, a fan 233, a fixed bearing 234, a rotating sleeve shaft 235, a sleeve shaft bearing 236, and a large variable speed motor 237. The fan tube is fixedly connected to the upper support and the lower support through the fan bracket, the fan tube is evenly distributed, the fan is installed in the fan tube, the fan shaft of the fan extends out of the fan tube, the fixed bearing is installed on the fan shaft of the fan, the fixed bearing and the lower support are directly mounted on the bracket, the rotating sleeve shaft is located at the center of the lower support and is connected to it through the sleeve shaft bearing, the rotating sleeve shaft is movably sleeved on the upper spray pipe, the large variable speed motor is installed on the lifting plate, the large variable speed motor and the rotating sleeve shaft are connected through a bevel gear set, and the rotating sleeve shaft and the fan shaft of the fan are connected through a bevel gear set.

[0034] In this embodiment, the speed of the fan 233 can be controlled by adjusting the speed of the large variable speed motor 237, and then the wind force of the fan tube 231 can be adjusted, so as to control the ejection range and ejection height of the water mist group, so that the device can spray accurately according to the actual situation to avoid the waste of water mist. Through the use of the rotating sleeve 235, on the one hand, the bevel gear set can be used to make multiple fan tubes 231 run synchronously, and on the other hand, the upper spray pipe 25 can smoothly transport dust suppression water.

[0035] It should be noted that the lifting mechanism is composed of three electric push rods 281, which are evenly distributed in the dust suppression bottom box and fixedly connected thereto. The telescopic ends of the electric push rods extend out of the dust suppression bottom box and are fixedly connected to the lifting plate.

[0036] In this embodiment, the electric push rod 281 is used to push the lifting plate 273 up and down, so that the height of the fan tube 231 and the spray nozzle 26 can be adjusted, so that the water mist can be projected to a higher height, so that the device can perform a wide range of spray dust suppression work.

[0037] It should be understood that the water supply mechanism includes a water supply box 291, a connecting pipe 292, filter cotton 293, a water supply pipe 294, a water supply pump 295, and a water supply hose 296.
