Description

Technical Field

[0001] This utility model relates to the field of dust removal equipment technology, specifically a dust suppression spray cart. Background Technology

[0002] Mine spray dust suppression devices refer to devices that use sprayed water mist and sprinkled water to moisten dust, causing it to settle, reducing the amount of dust in the air and suppressing the flying of dust.

[0003] Some existing dust suppression trolleys use spray carts to remove dust from tunnels. The water mist sprayed from multiple atomizing nozzles on the cart falls under its own weight, and the water mist sprayed from the atomizing nozzles is in the same direction as the cart's forward movement. The water mist falls slowly and comes into contact with the dust slowly, resulting in a slow dust reduction speed in the tunnel. Therefore, in order to solve the above technical problems, this utility model provides a dust suppression spray cart. Utility Model Content

The terms "vertical," "horizontal," "left," "right," and similar expressions used in this document are for illustrative purposes only.

[0027] Unless otherwise defined, all technical and scientific terms used herein have the same meaning as commonly understood by one of ordinary skill in the art to which this invention pertains. The terminology used herein is for the purpose of describing particular embodiments only and is not intended to be limiting of the invention. The term "and / or" as used herein includes any and all combinations of one or more of the associated listed items.

[0028] Please combine Figures 1 to 6 As shown, this utility model provides a dust suppression spray cart, including a mobile cart. The mobile cart consists of a support plate 1 and four wheels 2 rotatably mounted on the support plate 1. A push handle 3 is fixedly installed on one end of the support plate 1. A water tank 4 is fixedly installed on the upper surface of the support plate 1. A water spray pipe 7 is arranged above the support plate 1. Multiple horizontal atomizing nozzles 8 and multiple vertical atomizing nozzles 9 are fixedly installed on the water spray pipe 7. The multiple horizontal atomizing nozzles 8 and multiple vertical atomizing nozzles 9 are evenly spaced along the length of the water spray pipe 7. A water pump 5 is fixedly installed on the support plate 1. The water inlet of the water pump 5 is connected to the bottom of the water tank 4 through a connecting pipe 6. The water outlet of the water pump 5 is fixedly connected to the water spray pipe 7 through a connecting pipe assembly.

[0029] Multiple horizontal atomizing nozzles 8 spray water mist in the direction of the spray cart's movement, while multiple vertical atomizing nozzles 9 spray water mist vertically downwards. The water mist sprayed by the multiple vertical atomizing nozzles 9 has the jet force of the vertical atomizing nozzles 9, which causes the vertical atomizing nozzles 9 to reach the bottom of the tunnel more quickly, and to remove dust floating in the air more quickly, resulting in a faster dust reduction speed.

[0030] In addition, an air pipe 20 is fixedly installed above the water spray pipe 7. An air outlet 23 is fixedly installed on the air pipe 20. The opening of the air outlet 23 faces downward. An air pump 19 is fixedly installed on the mobile trolley. The air outlet of the air pump 19 is fixedly connected to the air pipe 20 through the air pipe assembly.

[0031] The air outlet 23 can spray downward-moving air, which can push the water mist at the top of the tunnel to the bottom of the tunnel, and can also accelerate the contact between the water mist and dust, further accelerating the dust reduction speed and improving the dust reduction efficiency.

[0032] To enable the spray cart to adapt to more tunnels, a fixed cylinder 13 is fixedly installed on the upper surface of the support plate 1. A threaded rod 14 is slidably installed inside the fixed cylinder 13. A slide bar 16 is fixedly installed on the inner surface of the fixed cylinder 13. A strip groove 17 adapted to the slide bar 16 is opened on the outer surface of the threaded rod 14. A fixed plate 12 is fixedly installed on the water spray pipe 7. The top end of the threaded rod 14 is fixedly connected to the fixed plate 12. A threaded sleeve 15 is rotatably installed on the top end of the fixed cylinder 13. The threaded sleeve 15 is threadedly connected to the threaded rod 14. By rotating the threaded sleeve 15, the threaded rod 14 can slide in the fixed cylinder 13, which can change the overall length of the fixed cylinder 13 and the threaded rod 14, thereby changing the height of the water spray pipe 7 and the air pipe 20. As a result, in different tunnels, the water spray pipe 7 and the air pipe 20 are located at the top of the tunnel, which can reduce dust in more tunnels.

[0033] The connecting pipe assembly consists of a sleeve 10 and an inner pipe 11. The sleeve 10 and the inner pipe 11 are slidably connected. The sleeve 10 is fixedly connected to the outlet end of the water pump 5, and the inner pipe 11 is fixedly connected to the spray pipe 7.

[0034] The duct assembly consists of an outer duct 21 and an inner duct 22. The outer duct 21 and the inner duct 22 are slidably connected. The bottom end of the outer duct 21 is fixedly connected to the air outlet of the air pump 19, and the top end of the inner duct 22 is fixedly connected to the air pipe 20.

[0035] Because there is a lot of dust in the tunnel, a lot of dust entering the air pump 19 can easily affect its service life. An air inlet pipe 24 is fixedly installed at the air inlet end of the air pump 19. An installation cylinder 25 is detachably installed on the air inlet pipe 24. A filter screen 26 is fixedly installed on the inner surface of the installation cylinder 25. The filter screen 26 can filter the dust and prevent too much dust from entering the air pump 19 and affecting its service life. A threaded head 27 is fixedly installed on the installation cylinder 25. The threaded head 27 is threadedly connected to the air inlet pipe 24, which facilitates the periodic replacement of the filter screen 26.

[0036] The above description is merely a preferred embodiment of this utility model and is not intended to limit the utility model in any way. Those skilled in the art can readily implement this utility model based on the accompanying drawings and the above description. However, any modifications, alterations, or equivalent variations made by those skilled in the art without departing from the scope of the utility model's technical solution, utilizing the disclosed technical content, are considered equivalent embodiments of this utility model. Furthermore, any equivalent changes, alterations, or variations made to the above embodiments based on the essential technology of this utility model are still within the protection scope of this utility model's technical solution.
