Description

Technical Field

[0001] This utility model belongs to the field of cleaning vehicle technology, specifically relating to a high-efficiency impact sandblasting suction cup. Background Technology

[0002] In modern urban environmental sanitation maintenance, cleaning vehicles play a crucial role. They are responsible not only for daily road sweeping but also for removing stubborn stains, graffiti, road markings, and pre-treatment before road repairs. Sandblasting, as a highly efficient surface treatment technology, is increasingly used in the cleaning vehicle field because it can quickly remove surface stains and deposits without causing excessive damage to the substrate. Traditional sandblasting equipment typically uses high-pressure gas to accelerate abrasive particles to extremely high speeds before spraying them onto the surface to be cleaned. Existing sandblasting devices mainly consist of a high-pressure gas tank, a spray gun, a sand hose, and a sand box. High-pressure gas propels abrasive particles onto the object, and the particles are then manually collected into the sand box for recycling. However, because the abrasive particles are ejected from the nozzle, the nozzle area is limited, resulting in a small sandblasting area, and manual collection of abrasive particles is inefficient. Utility Model Content

[0003] Therefore, this utility model aims to solve the problems of small sandblasting area and low efficiency of manual sand collection in the prior art.

[0004] Therefore, the technical solution adopted is a high-efficiency impact sandblasting suction cup of this utility model, including: a sandblasting suction cup housing, a front air nozzle and a rear air nozzle provided at the bottom of the sandblasting suction cup housing, a sand flow nozzle provided between the front air nozzle and the rear air nozzle, both the front air nozzle and the rear air nozzle being connected to the air inlet steel wire hose, the sand flow nozzle being connected to the sand leakage steel wire hose through a sand distribution box, multiple guide plates being provided in front of the front air nozzle, a sand suction port being provided in front of the guide plates, and the sand suction port being connected to the suction port steel wire hose.

[0005] Preferably, one end of the sand-leaking steel wire hose is connected to the sand-flowing nozzle through the sand distribution box, and the other end of the sand-leaking steel wire hose is connected to the bottom of the sand box.

[0006] Preferably, one end of the suction port steel wire hose is connected to the sand suction port, and the other end of the suction port steel wire hose is connected to one end of the suction tube. Several pressure-reducing grooves are provided on the side wall of the suction tube. An upwardly inclined sand-blocking plate is provided on the right side of the pressure-reducing groove. A shell is provided on the pressure-reducing groove. A first sand mesh is provided on the shell. A sand-falling chamber is provided at the top of the sand box. The other end of the suction tube enters the negative pressure chamber and extends into the sand-falling chamber.

[0007] Preferably, a second sand mesh is provided on the side wall of the sand-falling chamber, and a leather pad is provided on the top wall of the sand-falling chamber.

[0008] Preferably, a filter screen is installed on the top of the sandbox.

[0009] Preferably, the angle between the front and rear air vents and the ground is 30-40 degrees, and the height from the ground is 25-55mm.

[0010] Preferably, the angle between the deflector and the ground is 15-25 degrees, and the height from the ground is 15-35mm.

[0011] Preferably, the upper end of the sand suction port is circular, and the lower end of the sand suction port is composed of a lower plate and an upper plate. The width of the lower plate and the upper plate is the same as the width of the sandblasting suction cup housing. The opening distance between the lower ends of the lower plate and the upper plate is 30-35mm. The angle between the lower plate and the ground is 15-25 degrees, and the height of the lower plate from the ground is 5-15mm. The angle between the upper plate and the ground is 30-35 degrees, and the height of the upper plate from the ground is 35-50mm.

[0012] This utility model's technical solution has the following advantages: Sand flows out through the sand outlet between the front and rear air nozzles. The high-pressure air blown from the front and rear air nozzles propels the sand at high speed towards the ground. The high-speed airflow from the front and rear nozzles, combined with the suction force of the sand inlet, creates a high-speed airflow within the sandblasting suction cup housing, achieving sandblasting to clean ground deposits. Multiple guide plates reflect the sand multiple times, causing it to rub against the ground repeatedly, increasing the sandblasting area and improving efficiency. The sand sprayed onto the ground passes through the sand inlet and the suction hose, entering the negative pressure chamber via the suction pipe. A pressure-reducing device on the suction pipe lowers the flow rate, collecting the sand in the sand collection chamber. The negative pressure of the negative pressure chamber absorbs the dust and airflow drawn into the sand collection chamber. The sand then falls into the sand box through a filter, achieving sandblasting sand recycling, which is energy-saving and environmentally friendly.

[0025] This utility model provides a high-efficiency impact blasting suction cup, such as Figure 1-4As shown, the system includes: a sandblasting suction cup housing 1; a front air nozzle 2 and a rear air nozzle 3 are located at the bottom of the sandblasting suction cup housing 1; a sand-flowing nozzle 4 is located between the front air nozzle 2 and the rear air nozzle 3; both the front air nozzle 2 and the rear air nozzle 3 are connected to the air inlet steel wire hose 5; the sand-flowing nozzle 4 is connected to the sand-leaking steel wire hose 7 through a sand distribution box 6; the sand distribution box 6 is used to evenly distribute and control the amount of falling sand; an electric butterfly valve is installed on the sand-leaking steel wire hose 7 to control the opening or closing of the sand-leaking steel wire hose; multiple guide plates 8 are located in front of the front air nozzle 2; a sand suction port 9 is located in front of the guide plates 8; the sand suction port 9 is connected to the suction steel wire hose 10. One end of the sand-leaking steel wire hose 7 is connected to the sand-flowing nozzle 4 through the sand distribution box 6; the other end of the sand-leaking steel wire hose 7 is connected to the bottom of the sand box 11. One end of the suction hose 10 is connected to the sand suction port 9, and the other end is connected to one end of the suction pipe 12. Several pressure-reducing grooves 13 are provided on the side wall of the suction pipe 12. An upwardly inclined sand-blocking plate 14 is provided on the right side of each pressure-reducing groove 13. A shell 15 is provided on the pressure-reducing groove 13, and a first sand mesh 16 is provided on the shell 15. A sand-falling chamber 17 is provided at the top of the sand box 11. The other end of the suction pipe 12 enters the negative pressure chamber and extends into the sand-falling chamber 17. Airflow flows to the pressure-reducing groove 13, and the sand-blocking plate 14 prevents sand from entering the pressure-reducing groove. Air enters the shell 15 through the pressure-reducing groove 13 and then flows out through the first sand mesh 16, reducing pressure on the suction pipe 12 and simultaneously causing dust to fall into the negative pressure chamber. A second sand mesh 18 is provided on the side wall of the sand-falling chamber 17, further releasing the pressure from the suction pipe 12 and reducing pressure on the sand-falling chamber 17, causing dust to fall into the negative pressure chamber. Sand overcomes the negative pressure of the negative pressure chamber and flows into the sand box 11 by gravity. A leather pad 19 is installed on the top wall of the sand collection chamber 17 to reduce wear on the top wall. A filter screen 20 is installed on the top of the sand box 11 to filter out impurities or debris in the sand. The front air nozzle 2 and the rear air nozzle 3 are both at an angle of 30-40 degrees to the ground and at a height of 25-55 mm. The guide plate 8 is at an angle of 15-25 degrees to the ground and at a height of 15-35 mm. The lower end of the sand suction port 9 consists of a lower plate and an upper plate. The width of the lower plate and the upper plate is the same as the width of the sandblasting suction cup housing 1. The opening distance between the lower ends of the lower plate and the upper plate is 30-35 mm. The angle between the lower plate and the ground is 15-25 degrees and the height is 5-15 mm. The angle between the upper plate and the ground is 30-35 degrees and the height is 35-50 mm. The sand suction port 9 can provide stronger suction and improve sand collection efficiency. The bottom of the sandblasting suction cup housing 1 is also equipped with wheels, which facilitates the movement of the sandblasting suction cup housing 1 with the cleaning vehicle. When the sandblasting suction cup housing is not in use, the hydraulic rod retracts the sandblasting suction cup 1 upwards.

[0026] The working principle and beneficial effects of the above technical solution are as follows: When there are other attachments on the road surface, the high-pressure air from the high-pressure blower on the cleaning vehicle enters the air inlet steel wire hose 5, and is simultaneously sent to the front air nozzle 2 and the rear air nozzle 3. At this time, the electric butterfly valve opens the sand leakage steel wire hose 7. Through the height and gravity of the sand in the sand box and sand pipe, the negative pressure of the negative pressure chamber is overcome, and the sand flows out through the sand discharge nozzle 4 between the front air nozzle 2 and the rear air nozzle 3. The high-pressure air blown out by the front air nozzle 2 and the rear air nozzle 3 causes the sand to be shot towards the ground at high speed. Through the high-speed airflow of the front air nozzle 2 and the rear air nozzle 3 and the suction of the sand suction port 9, a high-speed airflow is formed in the sandblasting suction cup housing 1, realizing sandblasting to clean the attachments on the ground. Multiple guide plates 7 reflect the sand multiple times, causing the sand to rub against the ground multiple times, increasing the sandblasting area and sandblasting effect, and improving efficiency. The sand sprayed onto the ground passes through the sand suction port 9 and the suction steel wire hose 10, is depressurized by the suction pipe 12, is collected in the sand drop chamber 17, and falls into the sand box 11, realizing the recycling of sandblasting sand, which is energy-saving and environmentally friendly. The suction volume of the sand inlet 9 is 35-45% greater than the air volume of the front air nozzle 2 and the rear air nozzle 3. The excess air volume is discharged through the exhaust valve of the high-pressure blower.

[0027] Obviously, those skilled in the art can make various modifications and variations to this utility model without departing from its spirit and scope. Therefore, if these modifications and variations fall within the scope of the claims of this utility model and their equivalents, this utility model also intends to include these modifications and variations.
