[0002] A mobile multi-functional spray dust reduction device is a device used to reduce dust at construction sites, aiming to reduce dust at the construction site while avoiding damage to workers.

[0003] The patent with the patent announcement number CN215506127U involves a water storage tank: an installation frame is arranged on the water storage tank, and the installation frame is rotatably connected with a spray barrel through a rotating shaft. One end of the inner part of the spray barrel is provided with a blower, and the other end is provided with a spray frame. A water supply component for supplying water to the spray frame is arranged in the water storage tank. The bottom of the water storage tank is provided with rollers, and a water collection component is arranged on the water storage tank. This spray dust reduction device can not only freely move the device to any position on the construction site to achieve efficient spray dust reduction treatment for the construction site, but also, combined with the collection function of the water collection component, collect the water droplets dripping from the spray barrel, and enable the dripping water to flow back into the water storage tank for secondary use, thereby reducing the waste of water resources, improving the utilization rate of water resources, and further improving the working efficiency of the spray dust reduction device.

[0004] In the above patent, the water droplets dripping from the spray barrel can be collected, and the dripping water can flow back into the water storage tank for secondary use, thereby reducing the waste of water resources, improving the utilization rate of water resources, and further improving the working efficiency of the spray dust reduction device. However, there are still problems. When the water is recycled, a large amount of dust will enter, which is likely to block the nozzle, affect the next water spray volume, and at the same time, a large amount of dust will precipitate at the bottom of the water tank, affecting the subsequent water storage volume. Summary of the Invention

[0005] Aiming at the deficiencies of the prior art, the present invention provides a mobile multi-functional spray dust reduction device for construction sites, which solves the problems raised in the above background art.

[0006] To achieve the above objectives, the present invention is realized through the following technical solutions: A mobile multi-functional spray dust reduction device for construction sites includes a base. A water tank is fixedly installed on the top of the base, an electrical box is fixedly installed on the top of the base, a lifting column is fixedly installed on the top of the base, a movable block is fixedly installed on the top of the lifting column, a spray pipe is rotatably installed on the top of the movable block, a nozzle is arranged inside the left side of the spray pipe, a water pipe is connected to the top of the water tank, and a dust detection mechanism is arranged inside the spray pipe; Among them, the dust detection mechanism includes a rotating rod, a wind receiving plate, a telescopic device, a long rod, a scraper and a sieve plate. One end of the rotating rod is rotatably installed at the top of the inner wall of the nozzle end far from the nozzle head, the wind receiving plate is fixedly installed at the other end of the rotating rod, the telescopic device is fixedly installed at the nozzle end far from the nozzle head, one end of the long rod is fixedly installed at the output end of the telescopic device, the scraper is fixedly installed at the other end of the long rod, and the sieve plate is fixedly installed at the nozzle end far from the nozzle head; Among them, a cleaning mechanism for cleaning the nozzle head and a limiting mechanism for limiting the nozzle are provided at the end of the nozzle close to the nozzle head. When the scraper moves, the dust on the sieve plate will be scraped off. At the same time, when the scraper moves, it will drive the sliding plate to move. When the sliding plate moves, it will drive the valve to move. When the valve moves, the liquid flow rate above the water pipe will increase.

[0007] According to the above technical solution, the dust detection mechanism further includes a sliding plate, an elastic telescopic rod, a friction plate and a valve. The sliding plate is slidably installed at the end of the nozzle far from the nozzle head. The fixed end of the elastic telescopic rod is fixedly installed at the bottom of the nozzle end far from the nozzle head. The friction plate is fixedly installed at the bottom of the nozzle end far from the nozzle head. The valve is arranged on the circumferential surface of the water pipe. When the sliding plate moves, it will drive the valve to move. When the valve moves, the liquid flow rate above the water pipe will increase, increasing the external water content.

[0008] According to the above technical solution, the wind receiving plate contacts the telescopic device, the elastic telescopic rod contacts the friction plate, the sliding plate contacts the valve, and the scraper contacts the sieve plate. When the wind receiving plate contacts the telescopic device, the telescopic device will be activated. When the sliding plate moves, it will drive the valve to move.

[0009] According to the above technical solution, the cleaning mechanism includes a herringbone rod, an elliptical ring, a cylinder, a rotating column, a door frame, a toothed groove ring, a round rod, a ring, an inclined block, a brush and a gear. A first chute is provided on the long rod. One end of the herringbone rod is slidably installed in the first chute. The elliptical ring is fixedly installed at the other end of the herringbone rod. The rotating column rotatably penetrates through the inside of the movable block. The cylinder is fixedly installed at the end of the rotating column close to the elliptical ring.

The door frame is fixedly installed on the circumferential surface of the nozzle. The toothed groove ring is rotatably installed on the surface of the door frame close to the nozzle head. One end of the round rod is fixedly installed on the surface of the toothed groove ring far from the door frame. The ring is fixedly installed at the other end of the round rod. The inclined block is fixedly installed on the circumferential surface of the round rod. The brush is fixedly installed on the inner wall of the ring. When the round head column is pushed, it will drive the lower baffle to move. When the baffle moves, it will block the collection box under the bottom plate. When the round rod stops rotating, the inclined block will also stop moving. When the inclined block stops moving, it will not contact the round head column.

[0010] According to the above technical solution, the cleaning mechanism further includes a bottom plate, an elastic telescopic plate, a baffle, a round head column and a collection box. The bottom plate is fixedly installed at the bottom of the door frame. A second chute is opened at the top of the bottom plate. The fixed end of the elastic telescopic plate is fixedly installed inside the second chute. The baffle is fixedly installed at the free end of the elastic telescopic plate. The round head column is fixedly installed at the free end of the elastic telescopic plate. The collection box is fixedly installed at the bottom of the bottom plate. When the inclined block does not contact the round head column, the baffle will return to its original position driven by the elastic telescopic plate, so as not to block the collection box.

[0011] According to the above technical solution, the elastic telescopic plate contacts the inclined block, the tooth groove ring meshes with the gear, and the brush contacts the nozzle inside the spray pipe. When the ring rotates, it will drive the brush to rotate. When the brush rotates, it will contact the nozzle in front of the spray pipe to clean the nozzle of the spray pipe and prevent impurities in the water from blocking the nozzle.

[0012] According to the above technical solution, the limiting mechanism includes a flat plate, a moving rod, an elastic telescopic column, a clamping groove ring, a rocker, an L-shaped rod, a rotating rod, a preventive rod, a limiting rod, an elastic clamping column and a soft sheet. The flat plate is fixedly installed on the circumferential surface of the rotating column. The fixed end of the elastic telescopic column is fixedly installed on the surface of the movable block. The moving rod is fixedly installed at the free end of the elastic telescopic column. The clamping groove ring is fixedly installed on the surface of the movable block. The rocker is fixedly installed on the surface of the movable block. The L-shaped rod is slidably installed on the surface of the movable block. The rotating rod is rotatably installed on the surface of the lifting column. A third chute is opened on the surface of the lifting column. The preventive rod is slidably installed in the third chute. The fixed end of the elastic clamping column is fixedly installed on the surface of the lifting column. A clamping groove is opened at the free end of the elastic clamping column. The soft sheet is fixedly installed on the surface of the lifting column. The limiting rod is slidably installed on the surface of the lifting column. When the insertion timing is incorrect or not inserted, the moving rod will drive the preventive rod to move. When the preventive rod moves, it will contact the limiting rod. When the preventive rod contacts the limiting rod, it will drive the limiting rod to move.

[0013] According to the above technical solution, the limiting rod contacts the elastic clamping column, the preventive rod contacts the limiting rod, the L-shaped rod contacts the rotating rod, and the rotating rod contacts the preventive rod. When the preventive rod moves, it will contact the limiting rod. When the preventive rod contacts the limiting rod, it will drive the limiting rod to move. When the limiting rod moves, the limit on the elastic clamping column will be released.

[0014] The present invention provides a mobile multifunctional spray dust reduction device for construction sites, having the following beneficial effects: (1)In this invention, when the long rod moves, it drives the scraper to move. When the scraper moves, it scrapes the dust on the sieve plate, preventing the dust from blocking the sieve plate and reducing the water spraying amount of the machine. Since there is a friction plate beside the elastic telescopic rod, the return movement of the elastic telescopic rod will be very slow, avoiding the situation where the water flow opening time is not long enough and preventing the sudden opening or closing of the switch caused by possible human misoperation. Thus, the safety risk caused by improper switch operation is reduced, ensuring that the switch can be closed smoothly, improving the operation accuracy, and also avoiding excessive use frequency of the switch.

[0015] (2)In this invention, when the brush rotates, it contacts the nozzle in front of the spray pipe to clean the nozzle of the spray pipe, preventing impurities in the water from blocking the nozzle and thus cleaning the nozzle. When the round head column is pushed, it drives the baffle plate below to move. When the baffle plate moves, it seals the collection box under the bottom plate, preventing the accidentally leaked cleaning liquid from entering the collection box, reducing the pollution of the collected liquid and resource waste. At the same time, it can reduce the downtime caused by liquid leakage or pollution and improve production efficiency.

[0016] (3)In this invention, when the moving bar moves downward, it inserts into the card slot ring to limit the card slot ring, preventing the angle deviation caused by the water flow impact during the movement of the spray pipe and forcibly limiting the card slot ring. At the same time, during the movement of the elastic clamping column, it contacts the soft film, generating vibration, which makes it easier for the elastic clamping column to insert into the card slot ring, helping to ensure that the equipment or components will not accidentally fall off, thus avoiding potential safety accidents, reducing equipment damage and maintenance costs caused by loose fixation, extending the service life of the equipment, and reducing operation steps to make the operation more convenient.

Specific embodiments

[0019] Next, the technical solutions in the embodiments of the present invention will be clearly and completely described in conjunction with the accompanying drawings in the embodiments of the present invention. Obviously, the described embodiments are only a 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 those of ordinary skill in the art without creative efforts shall fall within the protection scope of the present invention.

[0020] Please refer to Figures 1 - 8 , an embodiment of the present invention is: a mobile multi-functional spray dust reduction device for a construction site, including a base 1, a water tank 2 is fixedly installed on the top of the base 1, an electrical box 3 is fixedly installed on the top of the base 1, a lifting column 4 is fixedly installed on the top of the base 1, a movable block 5 is fixedly installed on the top of the lifting column 4, a spray pipe 6 is rotatably installed on the top of the movable block 5, a spray head is arranged inside the left side of the spray pipe 6, a water pipe 7 is connected to the top of the water tank 2, and a dust detection mechanism is arranged inside the spray pipe 6; Among them, the dust detection mechanism includes a rotating rod 801, a wind receiving plate 802, a telescopic device 803, a long rod 804, a scraper 805 and a sieve plate 806. One end of the rotating rod 801 is rotatably installed at the top of the inner wall of the end of the spray pipe 6 far from the nozzle. The wind receiving plate 802 is fixedly installed at the other end of the rotating rod 801. The telescopic device 803 is fixedly installed at the end of the spray pipe 6 far from the nozzle. One end of the long rod 804 is fixedly installed at the output end of the telescopic device 803. The scraper 805 is fixedly installed at the other end of the long rod 804. The sieve plate 806 is fixedly installed at the end of the spray pipe 6 far from the nozzle, which can avoid the insufficient opening time of the water flow rate, and avoid the sudden opening or closing of the switch caused by possible misoperation of the operator, thereby reducing the safety risk caused by improper switch operation, ensuring that the switch can be smoothly closed, improving the accuracy of operation, and also avoiding the excessive use frequency of the switch.

[0021] The dust detection mechanism further includes a sliding plate 807, an elastic telescopic rod 808, a friction plate 809 and a valve 810. The sliding plate 807 is slidably installed at the end of the spray pipe 6 far from the nozzle. The fixed end of the elastic telescopic rod 808 is fixedly installed at the bottom of the end of the spray pipe 6 far from the nozzle. The friction plate 809 is fixedly installed at the bottom of the end of the spray pipe 6 far from the nozzle. The valve 810 is arranged on the circumferential surface of the water pipe 7. When the sliding plate 807 moves, it will drive the valve 810 to move. When the valve 810 moves, it will increase the liquid flow rate above the water pipe 7, increasing the external water content.

[0022] The wind receiving plate 802 contacts the telescopic device 803, the elastic telescopic rod 808 contacts the friction plate 809, the sliding plate 807 contacts the valve 810, and the scraper 805 contacts the sieve plate 806. When the wind receiving plate 802 contacts the telescopic device 803, the telescopic device 803 will be started. When the sliding plate 807 moves, it will drive the valve 810 to move.

[0023] During the operation of this embodiment: Push the base 1 to the designated position, fill the water tank 2 with water, turn on the electric box 3, and adjust the nozzle 6 on the movable block 5 on the lifting column 4 to the appropriate position through the rocker 105. When the nozzle 6 starts to work, it will suck the external air into the interior of the nozzle 6 through the sieve plate 806. When the sieve plate 806 is not blocked, the air receiving plate 802 on the rotating rod 801 will be blown into the air. When the dust content in the external air is relatively large, the sieve plate 806 will be blocked. When the sieve plate 806 is blocked, the air receiving plate 802 on the rotating rod 801 will move downward. When the air receiving plate 802 moves downward, it will contact the telescopic device 803. When the air receiving plate 802 contacts the telescopic device 803, the telescopic device 803 will be activated. When the telescopic device 803 is activated, it will drive the long rod 804 to move. When the long rod 804 moves, it will drive the scraper 805 to move. When the scraper 805 moves, it will scrape the dust on the sieve plate 806. At the same time, when the scraper 805 moves, it will drive the sliding plate 807 to move. When the sliding plate 807 moves, it will drive the valve 810 to move. When the valve 810 moves, it will increase the liquid flow rate above the water pipe 7, increasing the external water content. When the scraper 805 moves in the original direction, the sliding plate 807 will also move in the original direction driven by the elastic telescopic rod 808. However, since there is a friction plate 809 beside the elastic telescopic rod 808, the return movement of the elastic telescopic rod 808 will be very slow, avoiding the insufficient duration of the water flow opening.

[0024] Please refer to Figures 1 - 8, based on the above embodiments, in another embodiment of the present invention, a cleaning mechanism for cleaning the nozzle and a limiting mechanism for limiting the nozzle 6 are provided at one end of the nozzle 6 close to the nozzle head. The cleaning mechanism includes a herringbone rod 901, an elliptical ring 902, a cylinder 903, a rotating column 904, a door frame 905, a toothed groove ring 906, a round rod 907, a ring 908, an inclined block 909, a brush 910 and a gear 911. A first sliding groove is formed on the long rod 804, and one end of the herringbone rod 901 is slidably installed in the first sliding groove. The elliptical ring 902 is fixedly installed at the other end of the herringbone rod 901. The rotating column 904 rotatably penetrates through the inside of the movable block 5.

The gear 911 is fixedly installed at the other end of the rotating column 904. The door frame 905 is fixedly installed on the circumferential surface of the nozzle 6. The toothed groove ring 906 is rotatably installed on the surface of the door frame 905 close to the nozzle head. One end of the round rod 907 is fixedly installed on the surface of the toothed groove ring 906 away from the door frame 905. The ring 908 is fixedly installed at the other end of the round rod 907. The inclined block 909 is fixedly installed on the circumferential surface of the round rod 907. The brush 910 is fixedly installed on the inner wall of the ring 908, blocking the lower collecting box 916 to prevent the cleaning liquid from accidentally leaking into the collecting box 916, reducing the pollution and waste of resources of the collected liquid. At the same time, it can reduce the downtime caused by liquid leakage or pollution and improve production efficiency.

[0025] The cleaning mechanism further includes a bottom plate 912, an elastic telescopic plate 913, a baffle 914, a round head column 915 and a collecting box 916. The bottom plate 912 is fixedly installed at the bottom of the door frame 905. A second sliding groove is formed at the top of the bottom plate 912. The fixed end of the elastic telescopic plate 913 is fixedly installed inside the second sliding groove. The baffle 914 is fixedly installed at the free end of the elastic telescopic plate 913. The round head column 915 is fixedly installed at the free end of the elastic telescopic plate 913. The collecting box 916 is fixedly installed at the bottom of the bottom plate 912. When the inclined block 909 does not contact the round head column 915, the baffle 914 will return to its original position under the drive of the elastic telescopic plate 913, so as not to block the collecting box 916.

[0026] The elastic telescopic plate 913 contacts the inclined block 909, the toothed groove ring 906 meshes with the gear 911, and the brush 910 contacts the nozzle head inside the nozzle 6. When the ring 908 rotates, it will drive the brush 910 to rotate. When the brush 910 rotates, it will contact the nozzle head in front of the nozzle 6 to clean the nozzle head of the nozzle 6 and prevent impurities in the water from blocking the nozzle head.

[0027] The limiting mechanism includes a flat plate 101, a moving rod 102, an elastic telescopic column 103, a card slot ring 104, a rocker 105, an L-shaped rod 106, a rotating rod 107, a preventive rod 108, a limiting rod 109, an elastic clamping column 110 and a soft sheet 111. The flat plate 101 is fixedly installed on the circumferential surface of the rotating column 904. The fixed end of the elastic telescopic column 103 is fixedly installed on the surface of the movable block 5. The moving rod 102 is fixedly installed on the free end of the elastic telescopic column 103. The card slot ring 104 is fixedly installed on the surface of the movable block 5. The rocker 105 is fixedly installed on the surface of the movable block 5. The L-shaped rod 106 is slidably installed on the surface of the movable block 5. The rotating rod 107 is rotatably installed on the surface of the lifting column 4. A third chute is provided on the surface of the lifting column 4. The preventive rod 108 is slidably installed in the third chute. The fixed end of the elastic clamping column 110 is fixedly installed on the surface of the lifting column 4. A card slot is provided at the free end of the elastic clamping column 110. The soft sheet 111 is fixedly installed on the surface of the lifting column 4. The limiting rod 109 is slidably installed on the surface of the lifting column 4, which is beneficial to ensuring that the equipment or components will not accidentally fall off, thereby avoiding potential safety accidents, reducing equipment damage and maintenance costs caused by insecure fixation, prolonging the service life of the equipment, and reducing the operation steps to make the operation more convenient.

[0028] The limiting rod 109 is in contact with the elastic clamping column 110. The preventive rod 108 is in contact with the limiting rod 109. The L-shaped rod 106 is in contact with the rotating rod 107. The rotating rod 107 is in contact with the preventive rod 108. When the preventive rod 108 moves, it will be in contact with the limiting rod 109. When the preventive rod 108 is in contact with the limiting rod 109, it will drive the limiting rod 109 to move. When the limiting rod 109 moves, the limitation on the elastic clamping column 110 will be released.

[0029] During the operation of this embodiment: when the long rod 804 moves downward, it drives the V-shaped rod 901 to move downward. When the V-shaped rod 901 moves downward, it drives the elliptical ring 902 to move downward. When the elliptical ring 902 moves downward, it drives the cylinder 903 to move downward. When the cylinder 903 moves downward, it drives the rotating column 904 to rotate. When the rotating column 904 rotates, it drives the gear 911 to rotate. When the gear 911 rotates, it drives the tooth groove ring 906 above the door frame 905 to rotate. When the tooth groove ring 906 rotates, it drives the round rod 907 to rotate. When the round rod 907 rotates, it drives the ring 908 to rotate. When the ring 908 rotates, it drives the brush 910 to rotate. When the brush 910 rotates, it contacts the nozzle in front of the spray pipe 6 to clean the nozzle of the spray pipe 6, preventing impurities in the water from blocking the nozzle. When the round rod 907 rotates, it drives the inclined block 909 to rotate. When the inclined block 909 rotates, it contacts the round head column 915. When the inclined block 909 contacts the round head column 915, it pushes the round head column 915 to move. When the round head column 915 is pushed, it drives the lower baffle 914 to move. When the baffle 914 moves, it seals the collection box 916 below the bottom plate 912. When the round rod 907 stops rotating, the inclined block 909 also stops moving. When the inclined block 909 stops moving, it no longer contacts the round head column 915. When the inclined block 909 does not contact the round head column 915, the baffle 914 returns to its original position under the drive of the elastic telescopic plate 913, thus no longer sealing the collection box 916.

[0030] When the rotating column 904 moves, it drives the flat plate 101 to move. When the flat plate 101 moves, it contacts the moving bar 102. When the contact between the flat plate 101 and the moving bar 102 ends, it presses the moving bar 102 downward. When the moving bar 102 moves downward, it inserts into the card slot ring 104 to limit the card slot ring 104, preventing angle deviation caused by the water flow impact during the movement of the spray pipe 6. At the same time, when the flat plate 101 moves, it drives the L-shaped rod 106 to move. When the L-shaped rod 106 moves, it contacts the rotating bar 107, thus driving the rotating bar 107 to rotate. When the rotating bar 107 moves, it drives the preventive bar 108 to move upward, also inserting and limiting the card slot ring 104. When the insertion timing of the two is incorrect or not inserted, the moving bar 102 drives the preventive bar 108 to move. When the preventive bar 108 moves, it contacts the limiting rod 109. When the preventive bar 108 contacts the limiting rod 109, it drives the limiting rod 109 to move. When the limiting rod 109 moves, it releases the limit on the elastic clamping column 110. When the limit on the elastic clamping column 110 is released, it inserts into the card slot ring 104 to forcibly limit the card slot ring 104. At the same time, during the movement of the elastic clamping column 110, it contacts the soft sheet 111, thus generating vibration, making it easier for the elastic clamping column 110 to insert into the card slot ring 104. When the rotating column 904 stops rotating, the moving bar 102 returns to its original position under the drive of the elastic telescopic column 103.

[0031] Although embodiments of the present invention have been shown and described, it will be understood by those of ordinary skill in the art that various changes, modifications, substitutions and variations can be made to these embodiments without departing from the principles and spirit of the present invention, and the scope of the present invention is defined by the appended claims and their equivalents.
