[0024] Reference Figure 3-4 A plurality of locking holes 235 are arranged at even intervals on the outer wall of the connecting pipe at the other end of the recovery hose 23, and the locking holes 235 correspond to and match the dust recovery bucket 24. A groove body 241 is arranged on the outer wall of the extension part at the end of the dust recovery bucket 24, and a limit frame 242 is arranged at the notch of the groove body 241. A spring block 243 is installed in the groove body 241, and a limit bar 244 is arranged at the bottom of the spring block 243 to match the limit frame 242. A plurality of springs 245 are arranged between the bottom of the spring block 243 and the bottom of the groove body 241, and the plurality of springs 245 are arranged side by side. The mounting surface of the spring block 243 is an inclined surface, and the other side is a vertical surface, and the overall size of the spring block 243 matches the locking hole 235.

[0025] In the present invention, the rotating tube 21 and the rotating tube in the docking plate 22 realize low-friction rotation through the upper and lower rotating plates and the ball bearing 255, ensuring that the pipeline can flexibly adjust its direction. The block 222 and the telescopic block 233 realize "insertion and locking" through the inclined surface design, and the spring 234 provides elastic pressure to ensure sealing. The bucket design of the dust recovery bucket 24 expands the dust capture range, and the spring block 243 is pressed into the locking hole 235 through the spring 245 to realize "one-button disassembly" cleaning. Figure 3-4 .

[0026] Reference Figure 1-2 The dust recovery bucket 24 is generally bucket-shaped outwardly, the size of the extended portion at the end of the dust recovery bucket 24 is smaller than the size of the connecting pipe portion of the recovery hose 23, and the number of locking holes 235 matches the number of spring blocks 243. The opening size of the dust recovery bucket 24 should be at least larger than the cross-sectional size of the recovery hose 23.

[0027] Reference Figure 10-13Auxiliary positioning grooves 18 are provided on the inner walls on both sides of the telescopic groove 13, and positioning strips 35 are provided on the outer wall of the telescopic sleeve 32 corresponding to the auxiliary positioning grooves 18 on both sides. The movable plate 33 is located outside the movable groove 15 and extends, and a pedal 34 is connected with the movable plate 33 on the same side. The cross-sectional size of the pedal 34 is consistent with the external cross-sectional size of the movable plate 33, and a plurality of anti-slip grooves 36 are provided on the top of the pedal 34. Limiting components 37 are also provided on both sides of the base 12 outside the movable groove 15, and the limiting components 37 assist in limiting the movable plate 33.

[0028] Furthermore, the limiting assembly 37 includes a locking column 371 fixed on one side of the movable groove 15, a rotating shaft 372 is provided at the bottom of the locking column 371, a rotating arc block 373 is provided on the rotating shaft 372, a limiting baffle 374 is provided on the top of the rotating arc block 373, and a weight reduction hole 375 is opened in the middle of the rotating arc block 373.

[0029] Furthermore, the rotating arc block 373 is semicircular as a whole, and the corresponding weight-reducing hole 375 is also semicircular. The overall size of the limit baffle 374 is larger than the top size of the rotating arc block 373. The installation position of the limit assembly 37 satisfies the requirement that the movable plate 33 contacts the limit baffle 374 and rotates it 180 degrees when moving downward, and after rotation, the weight-reducing hole 375 matches the corresponding locking column 371 after being pressed.

[0030] Furthermore, when the telescopic sleeve 32 is fully extended, its bottom surface exceeds the lowest surface of the universal wheel 31 .

[0031] In the present invention, the bottom surface of the universal wheel 31 and the telescopic sleeve 32 exceeds the universal wheel 31 when the telescopic sleeve 32 is fully extended, so that the device can be stably parked. The rotating arc block 373 in the limit assembly 37 locks the movable plate 33 through the limit baffle 374, and the weight-reducing hole 375 reduces the operating force to ensure smooth switching between the mobile and fixed states.

[0032] A method for using a dust recovery device for processing a louvered sand tray comprises the following steps: S1. Rotate the arc block 373 in the limit assembly 37 to disengage the weight-reducing hole 375 from the locking column 371, release the restriction on the movable plate 33, and move the entire device to the vicinity of the processing area through the universal wheel 31. The universal wheel 31 provides 360° steering, which can easily adjust the position in a narrow space and reduce the burden of manual handling. The weight-reducing hole (375) of the rotating arc block 373 is designed to reduce the operating force and ensure a smooth unlocking process; S2. Press the pedal 34 on the same side downward to drive the movable plate 33 and the telescopic sleeve 32 to move vertically downward along the telescopic slot 13 until the bottom surface of the telescopic sleeve 32 touches the ground and exceeds the lowest surface of the universal wheel 31, so that the base 12 is lifted and the universal wheel 31 is off the ground. The rotating arc block 373 of the limit assembly 37 is rotated 180° so that the limit baffle 374 is against the bottom of the movable plate 33. At the same time, the weight-reducing hole 375 is aligned with the locking column 371. Press the rotating arc block 373 to complete the locking. After the telescopic sleeve 32 is fully extended, the device is fixed by a rigid support surface to avoid vibration or displacement during processing. The limit baffle 374 is automatically locked to ensure that the device will not move accidentally during high-speed dust recovery. S3, insert the rotating base 25 at the bottom of the rotating tube 21 into the mounting hole 11, and rotate clockwise to fix the upper rotating disk 251 and the lower rotating disk 252 to the dust recovery box 1 through the engagement of the rotating bar 253 with the rotating convex groove 16 and the rolling of the ball 255 in the rotating groove 17. The ball 255 reduces friction, so that the rotating tube 21 can be easily adjusted in angle to adapt to different processing positions. The rotating convex groove 16 and the groove 17 ensure that the pipeline will not be loosened due to the impact of airflow; S4. Insert the docking block 231 of the recovery hose 23 into the gap between the block 222 of the docking plate 22, rotate the hose so that the telescopic block 233 is squeezed into the empty slot 232 by the inclined surface, until it is fully inserted and the telescopic spring 234 rebounds, the block 233 pops out and is locked with the block 222 in an interlaced manner. The inclined surface design automatically compresses the block 233 when the hose is inserted, and automatically locks after being inserted into place without additional tightening. The interlaced locking structure ensures airflow sealing to prevent dust leakage; S5. Insert the end of the dust recovery bucket 24 into the butt joint of the recovery hose 23, press the spring block 243 so that its inclined surface is compressed into the groove body 241, and after the locking hole 235 is aligned, the spring 245 rebounds to make the spring block 243 snap into the locking hole 235. The inclined surface design of the spring block 243 makes installation easy, and the spring 245 provides a stable locking force for quick replacement. The bucket-shaped opening design improves dust suction efficiency and reduces escape; S6. Manually rotate the rotating tube 21 and the recovery hose 23 according to the processing position requirements, and use the ball 255 to align the dust recovery bucket 24 with the sand plate processing area. The rotating mechanism allows fine adjustment of the position of the recovery bucket 24 to ensure that the dust source is captured and reduce secondary dust. The ball 255 reduces the rotation resistance and the operation is more labor-saving; S7, start the shutter sand disc processing equipment, the dust is sucked in through the recovery bucket 24, and enters the dust recovery box 1 through the hose 23 and the rotating tube 21, and the dust accumulation in the box 1 is observed. The negative pressure system cooperates with the large-diameter hose 23 to ensure that the dust is quickly sucked in and reduce the pollution of the working environment. The transparent observation window or box door 4 is convenient for checking the dust accumulation and cleaning it in time; S8. Open the box door 4, clean the dust collected in the box body 1, press the spring block 243 to release the connection between the recovery bucket 24 and the hose 23, reversely rotate the recovery hose 23 to detach from the docking plate 22, and disassemble to clean or replace the parts. The large opening design of the box door 4 is convenient for completely emptying the dust and reducing the residue. The quick disassembly structure makes it easy to clean or replace the hose 23 and the recovery bucket 24, thereby extending the life of the equipment; S9, reversely rotate the arc block 373 of the limit assembly 37, release the moving plate 33, pull the pedal 34 upward, retract the telescopic sleeve 32 into the telescopic slot 13, and the universal wheel 31 touches the ground again. The linkage design of the pedal 34 enables the device to quickly switch between the fixed and mobile states, thereby improving work efficiency. The weight-reducing hole 375 reduces the rotation resistance, and the unlocking can be completed with one hand.

[0033] In the present invention, the rotating pipe and the large bucket mouth design improve the dust capture rate, the combination of the universal wheel 31 and the telescopic sleeve 32 meets the needs of different working conditions, the snap-on connection reduces tool dependence, the cleaning efficiency is improved by more than 50%, and the anti-slip pattern 36 and the weight-reducing hole 375 and other designs reduce operating fatigue.
