[0001] This invention relates to the field of airport sweeper technology, and more specifically to the blowing head of an airport sweeper. Background Technology
[0002] Currently, airport runways play a crucial role in the takeoff and landing of aircraft. Therefore, ensuring the cleanliness of airport runways is an important task. To ensure the smooth takeoff and landing of aircraft and to ensure that the runway surface is clean, free of debris, and safe for passengers, airport runway cleaning is a top priority and a very rigorous task. The cleaning requirements are extremely high, and even the smallest dust particles must be removed. Traditional vacuum cleaning is mainly suitable for cleaning large-sized debris, while small-sized debris and dust are more suitable for cleaning by blowing.
[0003] The existing airport cleaning vehicles' blowers can only blow in a single direction. The airflow direction inside the blower is not flexible or controllable, making it impossible to blow away stubborn dust or garbage from multiple angles with great force. It is also impossible to flexibly adjust the local airflow direction inside the shell or change the concentration point of the airflow at the blower's outlet. Summary of the Invention
[0004] To solve the above technical problems, the present invention provides a blowing head for an airport sweeping vehicle, including a housing. A rectifier assembly is fitted to both the upper and lower inner walls of the housing, and a long screw is threaded between the tail end of the rectifier assembly and the housing. A wind-gathering assembly is installed in the middle of the inner side of the housing, and a transverse torsion bar is installed at the tail end of the wind-gathering assembly. A steel strand is connected to the front end of the rectifier assembly. Several guide tubes are fixedly installed on the surface of the housing. A snap-fit connector is fixedly connected to the side of the tail end of the housing, and a pin is inserted into the snap-fit connector.
[0005] The rectifier assembly includes a rectifier board, a memory metal plate connected to the front end of the rectifier board, and a spring plate welded to the top of the memory metal plate;
[0006] The wind-gathering component includes a horn tube. Several wind-guiding blades are installed in a circular array on the outer surface of the horn tube. A reinforcing ring is provided on the wind-guiding blade and is located near the tail end of the horn tube through the wind-guiding blade. Fixing rings are symmetrically connected to the side of the tail end of the horn tube. A central connecting rod is connected to the inner side of the horn tube through a side rod. A hexagonal sleeve rod is installed at the tail end of the central connecting rod.
[0007] Preferably, the housing is designed as a flat, funnel-shaped container, and the snap-fit connector, in conjunction with the pin, is used to quickly assemble the housing with the sweeper.
[0008] Preferably, the top of the transverse torsion bar is disposed through the upper wall of the housing, a positioning sleeve is fixedly installed on the inner side wall of the housing, and the steel strand is connected to the rectifier assembly through the positioning sleeve and the guide tube.
[0009] Preferably, the tail end of the rectifier plate is positioned and installed with the housing by means of a long screw and a nut, and every two sets of nuts position and install the tail end of the rectifier plate on the long screw.
[0010] Preferably, the shape memory metal plate is used to restore the deformed spring plate to its initial state, and a knot for limiting the position is provided on the side where the steel strand passes through the spring plate, and all the knots are located on the side away from the guide tube.
[0011] Preferably, the fan blade penetrates the inner wall of the horn tube and is located on the inner side of the horn tube to form an acceleration plate.
[0012] Preferably, the reinforcing ring is installed at the tail end of the horn tube via the air intake blade, the fixing ring is connected to the horn tube as a whole, and the horn tube is rotatably installed with the housing through the cooperation of the fixing ring and the transverse torsion bar.
[0013] Preferably, the hexagonal sleeve is threadedly installed with the transverse torsion bar, the hexagonal sleeve is fitted with the tail end of the central connecting rod, and the horn is installed in combination with the transverse torsion bar through the cooperation of the central connecting rod and the hexagonal sleeve.
[0014] This invention provides a blowing head for an airport cleaning vehicle. It has the following beneficial effects:
[0015] 1. The blowing head of the airport sweeper can change the wind direction of the two sets of rectifier components installed side by side on the upper and lower side walls of the shell by pulling or releasing the steel rope installed on the shell. It can flexibly adjust the local airflow direction inside the shell and assist in blowing according to the distribution density of dust particles and small debris on the airport runway.
[0016] 2. The blowing head of the airport sweeper uses a memory metal plate to restore the deformed spring plate to its initial state. This allows the spring plate, which has been pulled in the opposite direction and deformed, to quickly return to its initial airflow angle under the action of the memory metal plate. This facilitates the auxiliary sweeping head in cleaning dust particles and small debris, and improves the flexible adjustment function of the wind force intensity and wind direction angle on the side of the blower head's air outlet.
[0017] 3. The blowing head of this airport sweeper can change the concentration point of the air force at the air outlet of the blowing head by rotating the horizontal torsion bar that runs through the top of the shell. This overcomes the drawback of traditional sweepers that can only blow in a single direction, and achieves powerful and directional blowing of dust at the front end of the blowing head.
[0018] 4. The blower head of this airport sweeper can change the airflow angle by slightly adjusting the deflection angle of the front end of the horn from inside the blower head. When encountering stubborn debris that is close to the runway surface, the blower head can be moved left and right repeatedly inside the shell to flexibly change the air outlet angle of the horn, so as to sweep stubborn dust or debris from multiple angles, improve the flexibility and controllability of the airflow direction inside the blower head, and realize the powerful cleaning function of the blower head.

Detailed Implementation
[0028] Example 1
[0029] like Figure 1 and Figure 2As shown, the present invention provides a technical solution: a blower head for an airport sweeper, comprising a housing 1, with a rectifier assembly 2 fitted to both the upper and lower inner surfaces of the housing 1, and a long lead screw 4 threaded between the tail end of the rectifier assembly 2 and the housing 1; a wind-gathering assembly 3 installed in the middle of the inner side of the housing 1, with a transverse torsion bar 5 installed at the tail end of the wind-gathering assembly 3; a steel stranded rope 6 connected to the front end of the rectifier assembly 2; several guide tubes 7 fixedly installed on the surface of the housing 1; a snap-fit connector 8 fixedly connected to the side of the tail end of the housing 1, with a pin 9 inserted through the snap-fit connector 8; the housing 1 is designed as a flat, funnel-shaped structure, and the snap-fit connector 8, in conjunction with the pin 9, is used to quickly assemble the housing 1 with the sweeper; the top of the transverse torsion bar 5 penetrates the upper wall of the housing 1, and a positioning sleeve is fixedly installed on the inner wall of the housing 1; the steel stranded rope 6 is connected to the rectifier assembly 2 through the positioning sleeve and the guide tubes 7.
[0030] In use, the housing 1 is quickly assembled with the sweeper by using the snap-fit connector 8 and the pin 9. The blower in the sweeper is started, which drives the airflow through the housing 1 and blows it toward the runway surface of the airport. Depending on the specific position of the sweeper on the side of the airport runway, the steel cable 6 is pulled or released, so that the airflow at the top and bottom of the inner side of the housing 1, guided by the rectifier assembly 2, blows dust particles and small debris to the side of the runway. The main air-gathering assembly 3 repeatedly shifts back and forth in the direction close to the runway from the center position. By rotating the transverse torsion bar 5, the air outlet of the air-gathering assembly 3 is adjusted to match the air blowing angle of the rectifier assembly 2, so as to uniformly sweep the dust particles and small debris on the runway surface.
[0031] Example 2
[0032] like Figure 2 , Figure 7 and Figure 8 As shown, the rectifier assembly 2 includes a rectifier plate 21, a memory metal plate 22 connected to the front end of the rectifier plate 21, and a spring plate 23 welded to the top of the memory metal plate 22; the tail end of the rectifier plate 21 is positioned and installed with the housing 1 through the cooperation of a long screw 4 and a nut, and every two sets of nuts position and install the tail end of the rectifier plate 21 on the long screw 4; the memory metal plate 22 is used to restore the deformed spring plate 23 to its initial state, and a knot for limiting the position is provided on the side through which the steel strand 6 passes through the spring plate 23, and the knots are all located on the side away from the guide tube 7.
[0033] When in use, by pulling or releasing the steel cable 6 installed on the housing 1, the wind direction of the two sets of rectifier components 2 installed side by side on the upper and lower side walls of the inner side of the housing 1 can be changed, and the local airflow direction inside the housing 1 can be flexibly adjusted. It can assist in blowing according to the distribution density of dust particles and small garbage on the airport runway.
[0034] The deformed spring plate 23 is restored to its initial state by the memory metal plate 22, so that the spring plate 23, which is pulled and deformed in the opposite direction, can quickly return to the initial flow angle under the action of the memory metal plate 22. This facilitates the auxiliary cleaning of dust particles and small debris by the auxiliary blowing head, and improves the flexible adjustment function of the wind force intensity and wind direction angle on the side of the blowing head air outlet.
[0035] Example 3
[0036] like Figure 2 , Figure 3 , Figure 4 , Figure 5 and Figure 6 As shown, the wind concentrator 3 includes a horn tube 31. A plurality of wind deflectors 32 are mounted in a circular array on the outer surface of the horn tube 31. Reinforcing rings 33 are provided on the wind deflectors 32, and are positioned near the tail end of the horn tube 31 via the wind deflectors 32. Fixing rings 34 are symmetrically connected to the side of the tail end of the horn tube 31. A central connecting rod 35 is connected to the inner side of the horn tube 31 via a side rod. A hexagonal sleeve rod 36 is installed at the tail end of the central connecting rod 35. The wind deflectors 32 penetrate the inner wall of the horn tube 31 and are positioned... An acceleration plate is formed on the inner side of the horn tube 31; a reinforcing ring 33 is installed at the tail end of the horn tube 31 via a fan blade 32; a fixing ring 34 is connected to the horn tube 31 as a whole; the horn tube 31 is rotated and installed with the housing 1 through the fixing ring 34 and the transverse torsion bar 5; a hexagonal sleeve rod 36 is threadedly installed with the transverse torsion bar 5; the hexagonal sleeve rod 36 is fitted with the tail end of the central connecting rod 35; the horn tube 31 is assembled and installed with the transverse torsion bar 5 through the cooperation of the central connecting rod 35 and the hexagonal sleeve rod 36.
[0037] When in use, by rotating the horizontal torsion bar 5 that runs through the top of the housing 1, the concentration point of the air force at the air outlet of the blower head can be changed, thus overcoming the drawback of traditional sweepers that can only blow in a single direction, and achieving powerful and directional blowing of dust at the front end of the blower head.
[0038] By slightly adjusting the deflection angle of the front end of the horn 31 inside the blower head, the blowing angle of the airflow can be changed. When encountering stubborn garbage that is close to the runway surface, the air outlet angle of the horn 31 can be flexibly changed by repeatedly moving it left and right inside the housing 1. This allows for multi-angle blowing of stubborn dust or garbage, improving the flexibility and controllability of the airflow direction inside the blower head, and realizing the powerful cleaning function of the blower head through reciprocating cleaning.
