Description

Technical Field

[0001] The invention belongs to the technical field of sanitation cleaning, and in particular relates to a high-speed and high-pressure blowing and suction cup for a sanitation cleaning vehicle. Background Art

[0002] The main structure of the existing blowing and suction suction cup is composed of front, rear, side wind nozzles or rear nozzles and a vertical dust suction port. The angle between the side wind nozzle and the dust suction port is 48-90 degrees. The dust and particulate garbage are blown to the dust suction port by front, rear, side blowing or rear blowing. When the suction cup moves, the wind on both sides and the front and back winds are opposite, causing vacuum in the suction port or pressure imbalance, which is easy to cause dust and reduce the dust suction effect, resulting in slow cleaning speed and low efficiency. The cleaning speed is less than 15Km / h, which is time-consuming and power-consuming. Therefore, it is necessary to propose improvements. Summary of the invention

[0003] The technical problem solved by the present invention is to provide a high-speed, high-pressure blowing and suction suction cup for a sanitation cleaning vehicle. The reasonable position and angle layout of the high-pressure air nozzles in the present invention and the refracted airflow make the dust and particulate garbage always in a suspended state. The wind pressure at the blowing port increases the flow rate of the negative pressure at the suction port, making it easier and faster to suck the garbage into the dust collection box, solving the problem of difficult cleaning and dust at the curb, thereby making the cleaning speed faster, the cleaning efficiency higher, and the cleaning cost lower.

[0004] The technical solution adopted by the present invention is as follows: a high-speed high-pressure blowing and suction type suction cup for a sanitation cleaning vehicle comprises a suction cup cover plate, a surrounding plate is arranged around the lower part of the suction cup cover plate, and the surrounding plate is arranged at one end of the suction cup in the forward direction of the suction cup; a dust suction port is arranged at the rear part of the lower part of the suction cup cover plate, and the suction port of the dust suction port is forward and has a gap with the ground and is communicated with the inside of the suction cup cover plate to form a guide channel; a guide flow channel is arranged below the suction cup cover plate and on both sides in front of the dust suction port, and a high-pressure air inlet is connected above the guide flow channel; a center dividing plate is arranged below the guide flow channel and in the middle of the front part of the dust suction port, a plurality of left and right high-pressure air nozzles are arranged on the left and right sides of the lower part of the guide flow channel, and the left and right high-pressure air nozzles are communicated with the high-pressure air inlet, an elastic front high-pressure air nozzle is arranged at the front end of the lower part of the suction cup cover plate, that is, just in front of the dust suction port, an elastic front outer high-pressure air nozzle is arranged on the outer side of the front part of the lower part of the suction cup cover plate, and the angles of the left and right high-pressure air nozzles, the elastic front high-pressure air nozzle, and the elastic front outer high-pressure air nozzle are concentrated toward the position of the dust suction port.

[0005] To further limit the above technical solution, the flow guide channel is a cone structure, and the angle between it and the dust suction port is 26-33 degrees; the multiple left and right high-pressure air nozzles are installed in a cone shape on both sides of the flow guide channel.

[0006] As a further limitation of the above technical solution, the elastic front high-pressure air nozzle and the elastic front outer high-pressure air nozzle are connected to the flow guide channel through an elastic tube.

[0007] To further limit the above technical solution, the angle between the left and right high-pressure air nozzles, the elastic front high-pressure air nozzle and the elastic front outer high-pressure air nozzle and the ground is 28-36 degrees, and the distance between them is 90-110 mm.

[0008] As a further limitation of the above technical solution, an anti-collision wheel is provided on the outer side of the front portion of the suction cup cover plate.

[0009] The advantages of the present invention compared with the prior art are:

[0010] 1. In this scheme, the elastic front outer high-pressure air nozzle blows the dust and garbage particles on the edge of the road into the front of the suction cup, and the elastic front high-pressure air nozzle directly blows into the negative pressure airflow formed by the dust suction port. The left and right high-pressure air nozzles blow the dust and garbage particles on both sides into the negative pressure airflow formed by the dust suction port, and accelerate the suspension of the particles blown up by the front air nozzle. The reasonable position and angle layout of each high-pressure air nozzle increase the flow rate of the suction port air volume to the blown airflow, so that the dust and particulate garbage are always in a suspended state, and the negative pressure formed by blowing to the dust suction port is easier and faster to be sucked into the dust collection box, which solves the problem of difficult cleaning and dust on the edge of the road, thereby making the cleaning speed faster and more efficient. The cleaning speed can reach 60Km / h, and the cost is low;

[0011] 2. This solution provides an anti-collision wheel on the front outer side of the suction cup cover plate. The anti-collision wheel on the front outer side has a telescopic function after contacting the curb, which effectively prevents the high-speed suction cup from colliding with the curb without being damaged.
