[0033] The present invention will now be described in further detail with reference to the accompanying drawings. These drawings are simplified schematic diagrams, illustrating only the basic structure of the present invention, and therefore only show the components relevant to the present invention.

[0034] like Figure 1-5 As shown, a portable sandblasting rust removal device includes: a sandblasting box 1, an observation window 2 detachably mounted on the top of the sandblasting box 1 by bolts, and two operation holes 3 provided on the front surface of the sandblasting box 1;

[0035] An assembly frame 4 is fixedly connected to the inner wall of the sandblasting box 1, and a sandblasting mechanism 5 is fixed on the assembly frame 4.

[0036] The bottom of the sandblasting box 1 is fixedly connected to a bracket 6, and the lower end of the bracket 6 is fixedly connected to several self-locking casters 7.

[0037] Feeding section 8, which is symmetrically arranged on both sides of the sandblasting box 1;

[0038] The support part 9 is sleeved on the outside of the sandblasting box 1;

[0039] Adjustment part 10, the adjustment part 10 is disposed on the support part 9;

[0040] Dust removal unit 11, wherein the dust removal unit 11 is installed inside the sandblasting box 1,

[0041] The adjustment part 10 is used to adjust the height of the bearing part 9 so that the plurality of self-locking casters 7 touch the ground;

[0042] The dust removal unit 11 is used to adsorb and collect dust inside the sandblasting box 1 and to clean the rust-removed workpieces.

[0043] In use, the operator loads abrasive through the feeding sections 8 on both sides, and supplies it to the sandblasting mechanism 5 through the storage hopper 37. Compressed air drives the abrasive to be sprayed out of the spray gun at high speed, impacting the surface of the workpiece to remove rust. The interception net 38 separates the recyclable abrasive, realizing recycling. During the sandblasting and rust removal operation of the workpiece, the observation window 2 allows the staff to easily observe the rust removal status of the workpiece. The two operation holes 3 allow the staff to easily reach into the sandblasting box 1 to hold the workpiece and operate the dust removal section 11.

[0044] When needed, several positioning bolts 19 can be loosened by rotating and the adjusting sleeve 18 can be slid up and down to control the vertical height adjustment of the sandblasting box 1. After adjustment, the positioning bolts 19 are locked after being aligned with the positioning holes 20 of the required height. The bearing rod 13 and the adjusting sleeve 18 form a rigid support structure to support the sandblasting box 1. The sandblasting box 1 can be controlled at different heights to adapt to different work requirements, such as desktop operation or ground standing operation, and is adapted to the height of the staff to improve the comfort of the staff. The bottom of the sandblasting box 1 can be controlled to contact the ground with several self-locking casters 7. At this time, the bearing part 9 and the sandblasting box 1 are folded and staggered. With the handle 16 in the bearing part 9, the bearing box can be dragged upright. The overall volume is small, which is suitable for handling and storage in narrow spaces, and meets the needs of outdoor operation or space-constrained places. When the sandblasting box 1 and the bearing part 9 are folded and transported, the bearing part 9 can effectively protect the sandblasting box 1 and prevent the sandblasting box 1 from being damaged by bumps during transportation.

[0045] During the sandblasting and rust removal process, the blower 22 generates negative pressure, drawing dust into the dust collection box 21 via the dust collection hose 24. This prevents dust from affecting the operator's observation of the workpiece. After rust removal, the operator can hold the control sleeve 26 and pull the dust collection hose 24. The counterweight 25 maintains the tension of the dust collection hose 24, and the guide wheel 23 restricts the movement trajectory, controlling the movement of the suction connector 27 within the sandblasting box 1. This ensures comprehensive dust removal within the sandblasting box 1, effectively handling dust in the corners and preventing secondary dust generation during workpiece handling, which would affect the operating environment. The drive motor 28 can drive the dust suction connector 27 and cleaning brush 31 to rotate through the drive gear 29 and the transmission gear ring 30. With the help of the dust collection hose 24, it can achieve simultaneous suction and brushing. After the workpiece is derusted, the surface of the workpiece can be cleaned by rotating the brush to avoid the presence of dust, abrasive or oxide scale on the workpiece. No additional manual cleaning is required afterward, reducing the overall operation time and effectively improving work efficiency. After cleaning, the control sleeve 26 is released, and the dust collection hose 24 is reset under the traction of the counterweight 25, which facilitates the dust removal operation during the subsequent sandblasting and derusting process of the workpiece.

[0046] Optionally, the supporting part 9 includes a supporting frame 12 movably sleeved on the outside of the sandblasting box 1; a plurality of supporting rods 13 fixed at the four corners of the lower surface of the supporting frame 12; a plurality of support legs 14 respectively fixed to the bottom of the plurality of supporting rods 13; and a plurality of connecting rods 15 for connecting the lower ends of the plurality of supporting rods 13.

[0047] The rear side of the support frame 12 is hinged with a handle 16. In use, the support part 9, together with the adjustment part 10, can support the sandblasting box 1, raising the sandblasting box 1 higher for easy operation by the staff. The adjustment part 10 can also control the folding of the support part 9 and the sandblasting box 1, reducing the overall volume by 40% to 50%. With the rotating and unfolding handle 16, it can be dragged upright, making it suitable for handling in narrow spaces. It is easy to move, effectively improving the application scenarios and meeting the needs of outdoor operations or space-constrained places. It is also convenient to store, carry and use.

[0048] Optionally, the adjusting part 10 includes a positioning frame 17 fixedly sleeved on the lower end of the outer wall of the sandblasting box 1; a plurality of adjusting sleeves 18 symmetrically fixed on both sides of the positioning frame 17 and movably sleeved on the outside of the plurality of bearing rods 13; a plurality of positioning bolts 19 symmetrically threaded on the plurality of adjusting sleeves 18; and a plurality of positioning holes 20 equally spaced on the plurality of bearing rods 13 and corresponding to the plurality of positioning bolts 19. In use, by rotating the plurality of positioning bolts 19, they can be inserted into the positioning holes 20 at different heights. The connection and disassembly of several support rods 13 and several adjustment sleeves 18 are completed, which facilitates the positioning of the support part 9 after adjusting the height of the sandblasting box 1. This allows the sandblasting box 1 to be at different heights to accommodate different operating postures of operators of different heights. When the support part 9 is adjusted to a certain height, most of the support part 9 overlaps with the sandblasting box 1, reducing the overall volume of the device. This also allows several self-locking casters 7 to contact the ground, so that the support part 9 does not support the sandblasting box 1, making it convenient to transport and store the sandblasting box 1 in narrow spaces.

[0049] Optionally, the dust removal unit 11 includes a dust collection box 21 fixed to the rear end of the sandblasting box 1; a fan 22 installed on the top of the dust collection box 21; two guide wheels 23 symmetrically installed on the sandblasting box 1; a dust collection hose 24 with one end connected to the lower end of the dust collection box 21 and the other end passing through the two guide wheels 23 and extending into the sandblasting box 1; and a counterweight 25 fixedly sleeved on the dust collection hose 24. During the sandblasting process controlled by the operator, the other end of the dust collection hose 24 remains stationary, and under the drive of the fan 22, it stably performs dust removal. After the sandblasting and rust removal work is completed, the operator can manually pull the dust collection hose 24 to move it, so that the other end of the dust collection hose 24 can be pulled to the desired position. The dust collection hose 24 is positioned to achieve large-scale dust removal within the sandblasting chamber 1, preventing dust accumulation in corners and quickly collecting and transporting airborne dust to the dust collection box 21. This prevents dust buildup within the sandblasting chamber 1, reduces cleaning time, and facilitates rapid replacement of workpieces after rust removal without causing dust to overflow from the sandblasting chamber 1, ensuring a safe working environment. When the operator releases the traction of the dust collection hose 24, the counterweight 25 pulls the other end of the hose back to its original position, facilitating dust removal during subsequent sandblasting and rust removal processes. During the traction and repositioning of the dust collection hose 24, the two guide wheels 23 effectively limit its range of motion, reducing wear and extending its service life.

[0050] Optionally, the dust removal unit 11 further includes a control sleeve 26 fixed to the other end of the dust collection hose 24; a suction connector 27 connected to the other end of the dust collection hose 24 via a rotary joint; a drive motor 28 fixed inside the control sleeve 26; a drive gear 29 fixed to the output end of the drive motor 28; a transmission gear ring 30 fixedly sleeved outside the suction connector 27 and meshing with the drive gear 29; a cleaning brush 31 detachably mounted on the suction connector 27; and a stainless steel filter screen 32 installed inside the cleaning brush 31. In use, the drive motor 28 drives the drive gear 29 to rotate, thereby driving the transmission gear ring... The 30-meshing drive dust suction connector 27 rotates within the control sleeve 26, thereby driving the cleaning brush 31 to rotate. This achieves simultaneous suction and brushing, allowing for cleaning of the workpiece surface after rust removal. This prevents dust, abrasive particles, or oxide scale from remaining on the workpiece and removes micron-level burrs generated by sandblasting, reducing subsequent processing operations and improving the cleaning efficiency of complex workpieces, avoiding manual rework. The stainless steel filter 32 prevents large abrasive particles from clogging the pipes. The cleaning brush 31 is removable and replaceable to ensure cleaning effectiveness and allows for easy replacement of the cleaning brush type according to the type of workpiece to be cleaned, achieving effective cleaning for different workpieces.

[0051] Optionally, the feeding section 8 includes two feeding slots 33 symmetrically opened on both sides of the sandblasting box 1; two doors 34 hinged to both sides of the sandblasting box 1 for closing the two feeding slots 33 respectively; two sealing rings 35 fixed to the two doors 34 and abutting against the outer walls of both sides of the sandblasting box 1 respectively; and two limiting blocks 36 rotatably connected to both sides of the sandblasting box 1 and abutting against the two doors 34 respectively. When the two doors 34 close the two feeding slots 33 respectively, the two limiting blocks 36 can be rotated to close the two feeding slots 33. The two door bodies 34 are engaged, which effectively restricts their movement and presses the two sealing rings 35 together, ensuring the sealing effect of the two sealing rings 35 and the two door bodies 34. This prevents dust from overflowing from the sandblasting chamber 1 and blocks external air from entering and affecting the negative pressure dust removal. At the same time, the symmetrically designed feeding trough 33 allows for the horizontal loading and unloading of large workpieces, enabling open sandblasting and rust removal operations. This avoids the limitation of operating space imposed by traditional top openings and effectively improves the practicality of the device. Furthermore, the hinge structure of the door body 34 supports rapid opening and closing, and the machine can be replenished without stopping the machine, facilitating quick replenishment of abrasive.

[0052] Optionally, the bottom of the sandblasting box 1 is connected to a storage hopper 37, and an intercepting net 38 is fixedly connected between the storage hopper 37 and the sandblasting box 1. During sandblasting or cleaning of the workpiece, excess abrasive can fall into the storage hopper 37 through the intercepting net 38, making it convenient for reuse and extending the continuous working time of the equipment.

[0053] The above description is merely a preferred embodiment of this utility model and is not intended to limit the utility model. Various modifications and variations can be made to this utility model by those skilled in the art. Any modifications, equivalent substitutions, improvements, etc., made within the spirit and principles of this utility model should be included within the protection scope of this utility model.
