Description

Technical Field

[0001] The present invention relates to the technical field of spray dust suppression, and particularly to a spray dust suppression device for a backhoe excavator. Background Art

[0002] A backhoe excavator is the most widely used earth excavation machinery in engineering construction. It has the characteristics of flexible operation and fast slewing speed, and is mainly used for the excavation of foundation pits (trenches) or pipe trenches, independent foundation pits and slopes below the working surface. Since a large amount of dust is generated during the operation of a backhoe excavator, a spray dust suppression device is often required to handle the dust. Spray dust suppression mainly uses high pressure to atomize water or other dust suppressant solutions into tiny water droplets through a nozzle. These tiny water droplets collide with and adsorb the dust, causing the dust to agglomerate and increase in weight, and thus settle to the ground to achieve the purpose of reducing the dust concentration.

[0003] The spray dust suppression device is usually installed near the working area of the backhoe excavator. However, when the existing spray dust suppression device is installed on the backhoe excavator, it is difficult to adjust the distance from the working area, which is likely to affect the spray dust suppression effect.

[0044] A hydraulic push rod 307, with a second fixing block 308 provided on the driving shaft of the hydraulic push rod 307;

[0045] One side of the water storage tank 301 is fixedly connected to one side of the first fixing block 302, the bottom of the first fixing block 302 is fixedly connected to the top of the hydraulic push rod 307, the driving shaft of the hydraulic push rod 307 is fixedly connected to the top of the second fixing block 308, one side of the second fixing block 308 is fixedly connected to one side of the square water tank 305, the water inlet at the top of the square water tank 305 is communicated with the bottom of the water passing hose 303, the top of the water passing hose 303 is communicated with the water outlet of the high-pressure water pump 304, the water inlet of the high-pressure water pump 304 is communicated with the bottom of the water storage tank 301, and the top of the atomizing circular plate 306 penetrates through the bottom of the square water tank 305 and is fixedly connected to the square water tank 305;

[0046] One side of the water storage tank 301 is fixedly connected to one side of the bucket rod 1.

[0047] A diffusion assembly 309 is fixedly connected to the bottom of the square water tank 305, a cleaning assembly 310 is fixedly connected to the outside of the diffusion assembly 309, T-slot clamping plates 311 are fixedly connected to both sides of the inner wall of the square water tank 305, a T-shaped slider 312 is slidably connected to the inner wall of the T-slot clamping plate 311, a circular baffle 313 is fixedly connected to one side of the T-shaped slider 312, and a retraction spring 314 is fixedly connected to the top of the circular baffle 313;

[0050] During use, the atomizing dust suppression mechanism 3 performs spray dust suppression treatment on the bucket 2 and its nearby working area. At the same time, the atomizing dust suppression mechanism 3 can also adjust the spray distance from the bucket 2 to avoid affecting the spray dust suppression effect of the atomizing dust suppression mechanism 3; the high-pressure water pump 304 pumps the water in the water storage tank 301 into the water passing hose 303 and into the square water tank 305. The water entering the square water tank 305 contacts the circular baffle 313 and diffuses around the circular baffle 313, and is atomized and sprayed out in the diffusion assembly 309 through the atomizing circular plate 306. The atomized liquid droplets are diffusely atomized and dust suppressed through the diffusion assembly 309; the hydraulic push rod 307 drives the drive shaft to push the second fixing block 308 to drive the square water tank 305 to move to adjust the distance from the bucket 2, so that the distance between the atomizing dust suppression mechanism 3 and the working area of the bucket 2 is adjustable, improving the spray dust suppression effect; when the water flow in the water passing hose 303 surges into the interior of the square water tank 305, it pushes the circular baffle 313 to move downward and pulls the retraction spring 314 to stretch. By arranging the circular baffle 313 inside the square water tank 305 to resist the water flow, it prevents the water flow entering the square water tank 305 from directly passing through the position near the central area of the atomizing circular plate 306 and atomizing and spraying out, resulting in poor atomizing spray and uneven dust suppression effect; when the circular baffle 313 moves downward, it drives the T-shaped circular blocks on both sides to slide on the inner wall of the T-slot card plate 311. By arranging the T-slot card plate 311 and the T-shaped slider 312 on both sides of the circular baffle 313 to be clamped and matched, the sliding limit of the circular baffle 313 is carried out to prevent the retraction spring 314 from being pulled and tilted and bent when the water flow thrust is uneven, affecting the water blocking effect of the circular baffle 313; when the water flow fills the interior of the square water tank 305 and the water flow impact on the circular baffle 313 becomes small, the retraction spring 314 drives the circular baffle 313 to move upward to the initial position through the retraction force, preventing the circular baffle 313 from gradually approaching the atomizing circular plate 306 and affecting the water flow efficiency through the atomizing circular plate 306 when the circular baffle 313 continuously moves downward.

[0051] Please refer to Figures 1 - 8, the diffusion component 309 includes an externally threaded ring plate 3091. The inner wall of the externally threaded ring plate 3091 is fixedly connected with a cross-shaped fixing rod 3092. The bottom of the cross-shaped fixing rod 3092 is fixedly connected with a circular blocking block 3093. The outside of the externally threaded ring plate 3091 is sleeved and threadedly connected with an internally threaded sleeve plate 3094. The bottom of the internally threaded sleeve plate 3094 is provided with a bottom-opening round hole 3095. The outer wall of the internally threaded sleeve plate 3094 is provided with an externally communicating round hole 3096. The top of the externally threaded ring plate 3091 is fixedly connected with the bottom of the square water tank 305. The externally threaded ring plate 3091 is located directly below the atomizing circular plate 306. The inner diameter of the externally threaded ring plate 3091 matches the outer diameter of the atomizing circular plate 306. The outer wall of the internally threaded sleeve plate 3094 is fixedly connected with one side of the cleaning component 310. There are multiple externally threaded ring plates 3091, and the multiple externally threaded ring plates 3091 are distributed at the bottom of the square water tank 305. There are multiple externally communicating round holes 3096, and the multiple externally communicating round holes 3096 are evenly distributed on the outer wall of the internally threaded sleeve plate 3094.

[0052] The cleaning component 310 includes a first connecting block 3101. The top of the first connecting block 3101 is fixedly connected with a top circular rod 3102. The outside of the top circular rod 3102 is fixedly connected with a brush 3103. The bottom of the first connecting block 3101 is fixedly connected with an upper top spring 3104. The bottom of the upper top spring 3104 is fixedly connected with a second connecting block 3105. The top of the second connecting block 3105 is fixedly connected with a corrugated ring piece 3106. The second connecting block 3105 is slidably connected through a bottom piercing rod 3107. One side of the first connecting block 3101 is slidably connected with the outside of the internally threaded sleeve plate 3094. One side of the second connecting block 3105 is fixedly connected with the outside of the internally threaded sleeve plate 3094. The top of the corrugated ring piece 3106 is fixedly connected with the bottom of the first connecting block 3101. The top of the bottom piercing rod 3107 is fixedly connected with the bottom of the first connecting block 3101.

[0053] When in use, the atomized droplets sprayed from the atomizing circular plate 306 enter the external threaded ring plate 3091 and pass through the circular block 3093 to diffuse and spray through the bottom circular hole 3095 and the external circular hole 3096 of the internal threaded sleeve 3094; by opening a plurality of external circular holes 3096 on the outer wall of the internal threaded sleeve 3094, it is convenient for the internal atomized droplets to diffuse and spray from the outside, preventing the atomized droplets sprayed from the atomizing circular plate 306 from atomizing and reducing dust only in the working area of ​​the bucket 2 but being difficult to atomize and reduce dust in the nearby area; by rotating the internal threaded sleeve 3094 and the external threaded ring plate 3091 for threaded matching, the internal threaded sleeve 3094 can move up and down, and when the internal threaded sleeve 3094 moves up and down, the external circular holes of the external threaded ring plate 3091 are used to The coverage degree of 3096 is used to adjust the displacement of the atomized droplets through the external circular hole 3096, so as to prevent the atomized droplets from being sprayed in large quantities when there is less diffuse dust in the area near the bucket 2, causing waste and affecting the working efficiency of the bucket 2; when the internal threaded sleeve 3094 rotates and moves upward, the bottom opening circular hole 3095 approaches the circular block 3093 in the external threaded ring plate 3091, and when the internal threaded sleeve 3094 continues to rotate and move upward, the circular block 3093 will insert and block the bottom opening circular hole 3095, so as to prevent the dust in the working area from gradually diffusing and accumulating in the internal threaded sleeve 3094 when there is no need to perform atomization and dust reduction on the area near the bucket 2, affecting the use; the internal threaded sleeve 3094 is reversed and moved downward until it is out of the thread cooperation with the external threaded ring plate 3091 The threads can be disassembled to clean the internal thread sleeve 3094 and the external thread ring plate 3091, so as to prevent the internal thread sleeve 3094 and the external thread ring plate 3091 from gradually accumulating too much mud and dust after being used for a long time in a dusty environment and affecting the use effect; after cleaning, the internal thread sleeve 3094 can be sleeved on the external thread ring plate 3091 and rotated upward for thread installation. At this time, when the internal thread sleeve 3094 rotates upward, it drives the outer cleaning component 310 to rotate upward together. When the internal thread sleeve 3094 rotates upward, the second connecting block 3105 and the first connecting block 3101 drive the top round rod 3102 and the brush 3103 to rotate upward together. When the brush 3103 rotates upward, it rubs and cleans the outer surface of the external thread ring plate 3091 , to prevent uncleaned dust particles from remaining on the threaded surface of the external threaded ring plate 3091 that is about to be threaded with the internal threaded sleeve plate 3094, thereby affecting the assembly effect; when the top round rod 3102 moves up to the top and contacts the bottom of the square water tank 305, it is pushed downward and drives the bottom penetration rod 3107 to move downward together. At the same time, when the first connecting block 3101 moves downward, the top spring 3104 and the corrugated ring piece 3106 at the bottom are compressed together. By arranging an easy-to-compress top spring 3104 at the bottom of the first connecting block 3101, the top round rod 3102 can move downward, preventing the top of the top round rod 3102 from causing resistance to the internal threaded sleeve plate 3094 when contacting the square water tank 305, so that the internal threaded sleeve plate 3094 cannot continue to move up and affect the use;By arranging a corrugated ring piece 3106 outside the upper top spring 3104 to stretch or contract together with the upper top spring 3104 and wrap and protect the upper top spring 3104, it is prevented that the upper top spring 3104 gradually adheres to too much mud and ash on the surface of the dusty working area for a long time, affecting its use; by arranging a bottom through rod 3107 penetrating the second connecting block 3105 at the bottom of the first connecting block 3101 to perform sliding limit on the elastically connected first connecting block 3101, it is prevented that the first connecting block 3101 rotating with the internal thread sleeve plate 3094 is tilted and offset outward under the action of centrifugal force, making it difficult for the brush 3103 to clean the external thread ring plate 3091 when moving upward.
