Description

Technical Field

[0001] The utility model belongs to the technical field of building construction, in particular to a dust suppression device for building construction. Background Art

[0002] During the construction process, workers often use building materials such as sand and lime, and construction vehicles travel frequently. Therefore, a lot of dust is inevitably generated in the construction area. Especially in dry climates, these dusts will float around at will, seriously polluting the environment. In order to remove these dusts, relevant workers often use dust reduction devices for dust reduction treatment. According to the patent document with the authorization announcement number: CN218392862U, entitled "A Dust Reduction Device for Construction", a hydraulic cylinder, a rotating column, a mounting plate and a rotating nozzle are provided. During the dust reduction process, the height of the hydraulic cylinder is adjusted according to the height requirements. The hydraulic cylinder drives the rotating column to move up and down, and drives the rotating column to make a 360° horizontal reciprocating rotation. The movement of the rotating column drives the mounting plate and the rotating nozzle to rotate in the horizontal direction, so that the dust reduction range of the rotating nozzle is large, the hydraulic cylinder is easy to adjust, and the adjustment of the rotating nozzle is convenient. At the same time, the dust reduction range is increased, the dust reduction efficiency is improved, and the height adjustment effectively prevents the dust from staying in the air for a long time. However, there are still the following defects:

[0003] The opening of the rotary nozzle faces upward, and the rotary nozzle can only rotate in the horizontal direction, so the spraying range is small, resulting in poor dust reduction effect. Utility Model Content

DETAILED DESCRIPTION

[0023] The technical solutions in the embodiments of the present invention will be clearly and completely described below in conjunction with the drawings in the embodiments of the present invention. Obviously, the described embodiments are only part of the embodiments of the present invention, rather than all the embodiments; based on the embodiments of the present invention, all other embodiments obtained by ordinary technicians in this field without making creative work are within the scope of protection of the present invention.

[0024] Embodiment 1, by Figure 1-2 The utility model relates to a dust suppression device for construction, comprising a base 1, universal wheels 3 are mounted at equal angles on the bottom of the base 1, and a spray mechanism 2 is provided on the top of the base 1.

[0025] Specifically, by Figure 2-4It is given that the spray mechanism 2 includes a U-shaped frame 201 located above the base 1, and a cylinder 209 is fixedly installed between the bottom of the U-shaped frame 201 and the top of the base 1. The inner side of the U-shaped frame 201 is symmetrically connected to a support shaft 2011 and a drive shaft 2014, and an adjusting cylinder 204 is fixedly connected between the support shaft 2011 and the drive shaft 2014. A plurality of nozzles 2016 are fixedly connected to both sides of the adjusting cylinder 204 at equal distances, and a nozzle 2015 is fixedly connected to the end of each nozzle 2016 away from the adjusting cylinder 204. A water tank 208 is fixedly installed on the top of the base 1, and a water injection pipe 207 is fixedly installed on the top of the water tank 208. A sealing plug is provided on the water injection pipe 207. A water pump 2013 is fixedly installed on the inner side of the U-shaped frame 201, and a water extraction pipe 205 is fixedly connected between the water pump 2013 and the water tank 208. The water extraction pipe 205 runs through the U-shaped frame. 201, a water pipe 2012 is fixedly connected between the water pump 2013 and the regulating cylinder 204, and the water pumping pipe 205 and the water pipe 2012 are both corrugated hoses. A large gear 203 is fixedly installed on the outside of the driving shaft 2014, and a support plate 2018 is fixedly installed on the inside of the U-shaped frame 201. A rotating shaft 2017 is rotatably connected between the support plate 2018 and the U-shaped frame 201, and a small gear 2019 is fixedly installed on the outside of the rotating shaft 2017. The small gear 2019 is meshed with the large gear 203. A vertical plate 2010 is fixedly installed on the top of the base 1, and a toothed plate 202 is fixedly installed on the side of the vertical plate 2010 close to the rotating shaft 2017. The toothed plate 202 is meshed with the small gear 2019. The toothed plate 202 does not contact the large gear 203, and the sum of the width of the toothed plate 202 and the width of the large gear 203 is less than the width of the small gear 2019.

[0026] When in use, water is first injected into the water tank 208 from the water injection pipe 207, and then the water pump 2013 is started. The water in the water tank 208 is extracted through the water extraction pipe 205 and enters the regulating cylinder 204 through the water delivery pipe 2012. Subsequently, the water is sprayed out from each nozzle 2015 through each nozzle pipe 2016 to realize the spraying and dust reduction work. When the cylinder 209 is started, the U-shaped frame 201 is driven to move longitudinally to adjust the height of each nozzle 2015, and at the same time drive the pinion 2019 and the large gear 203 to move longitudinally. Since the pinion 2019 is meshed with the tooth plate 202, the pinion 2019 and the rotating shaft 2017 are driven to rotate. Since the pinion 2019 is meshed with the large gear 203, the large gear 203 and the drive shaft 2014 are driven to rotate, and the regulating cylinder 204 and each nozzle 2015 are driven to rotate, and finally the spray range is increased to improve the dust reduction effect.

[0027] Specifically, by Figure 5Two guide posts 2020 are symmetrically fixedly connected to the top of the base 1, and the U-shaped frame 201 is located between the two guide posts 2020. The tops of the two guide posts 2020 are fixedly connected to the top blocks 2021, and the outer sides of the two guide posts 2020 are movably sleeved with guide plates 206, and the two guide plates 206 are fixed to the outer sides of the U-shaped frame 201;

[0028] In use, when the U-shaped frame 201 moves longitudinally, it drives the two guide plates 206 to slide along the two guide posts 2020 respectively, limiting the U-shaped frame 201, thereby ensuring the stability of the U-shaped frame 201 during movement.
