Description
Technical Field
The application relates to the field of environmental sanitation equipment, in particular to a cleaning vehicle suction nozzle and a cleaning vehicle with the same.
Background
Fig. 1 shows a schematic structure of a suction nozzle of a cleaning vehicle according to the prior art. Fig. 2 shows a schematic view of the structure of the underside of a suction nozzle of a prior art cleaning vehicle. As shown in fig. 1 and 2, the suction nozzle of the cleaning vehicle of the prior art comprises a housing 1 with an opening at the lower side, a suction cavity 2 surrounded by the housing 1, a suction opening 3 provided at the top of the housing 1, and an air duct 4 communicating with the suction opening 3. The air pipe 4 is communicated with a fan of the cleaning vehicle, and the suction opening 3 sucks garbage in a sweeping range of the suction cavity 2 into a garbage bin of the cleaning vehicle under the action of the fan.
The suction port 3 is positioned at the rear end of the suction cavity 2, and in the process of working the cleaning trolley suction nozzle, garbage moves to the rear end of the suction cavity 2 under the action of wind force and enters the dustbin through the suction port 3 and the wind pipe 4.
When the cleaning vehicle works, the cleaning vehicle suction nozzle sucks garbage in the travelling process of the cleaning vehicle, and due to the fact that the garbage is heavy or the travelling speed of the cleaning vehicle is high, the cleaning vehicle suction nozzle can not timely suck the garbage in a passing range into the dustbin completely, and after the cleaning vehicle continues to move forwards, the garbage which cannot be sucked away in time is out of the suction range of the cleaning vehicle suction nozzle, so that the suction leakage phenomenon occurs. In order to solve the above-mentioned problems, the suction nozzle of the cleaning truck of the prior art further comprises an air duct 5 provided behind the suction port 3, and the air intake of the air duct 5 blows the garbage forward so that the garbage is within the suction range of the suction port 3.
The above-described air duct 5 includes a first air duct 5a extending forward in the top-to-bottom direction and a second air duct 5b communicating with the lower end of the first air duct 5a, the second air duct 5b extending forward from the lower end of the first air duct 5 a.
However, the size of the suction nozzle of the cleaning vehicle in the travelling direction of the cleaning vehicle in the prior art is smaller, and the suction nozzle of the cleaning vehicle is still easy to leak when the speed of the cleaning vehicle is higher.
In addition, the lower end areas of the suction cavity 2 and the suction opening 3 of the suction nozzle of the conventional cleaning vehicle form a large-area low-speed vortex area during operation, so that energy loss is caused, and the operation efficiency is reduced.

The first suction chamber 3 is communicated with the second suction chamber 4, and in the forward process of the cleaning vehicle, the garbage in the first suction chamber 3 cannot enter the suction port 2 in time, and possibly enters the first suction chamber 3 or below the first suction chamber 3.
The first suction chamber 3 communicates with the suction opening 2, and the waste in the first suction chamber 3 or below the first suction chamber 3 can also enter the suction opening 2 under the action of suction force and be sucked away by the suction opening 2. Therefore, the problem that the suction nozzle of the cleaning vehicle in the prior art cannot completely suck the garbage in the working range into the dustbin is solved.
Further, the cleaning vehicle suction nozzle further comprises a guiding component 5 arranged in the first suction chamber 3, wherein the guiding component 5 is used for guiding the inlet air of the first suction chamber 3 to the front of the guiding component 5, so that the intersection point of the inlet air of the first suction chamber 3 and the inlet air of the second suction chamber 4 moves towards the second suction chamber 4, and the intersection point is generally the starting point of upward movement of garbage.
The flow guiding component 5 guides the air inlet of the first suction chamber 3 towards the second suction chamber 4, and simultaneously blows the garbage to move towards the second suction chamber 4, so that the time of the garbage in the suction range of the suction port 2 is prolonged, and the probability of the garbage being sucked by the suction port 2 is increased.
In this embodiment, the width of the second suction chamber 4 increases in a direction away from the suction port 2, thereby facilitating convergence toward the suction port 2. Further, the garbage which is not sucked by the suction port 2 in time is also collected in the first suction chamber 3.

The lower end of the flow guiding member 5 is higher than the lower end surface of the housing 1 so that the intake air of the first suction chamber 3 flows toward the suction port 2 or the second suction chamber 4. Optionally, the lower end of the flow guiding member is 5 to 30 mm higher than the lower end of the housing 1.
The flow guiding member 5 comprises a concave surface 53, the concave surface 53 facing the second suction chamber 4 for buffering the waste moving towards the first suction chamber 3, the buffered waste being also able to be sucked away by the suction opening 2.

The air duct 6 extends downward in an outside-in direction and extends toward the suction port 2 in an outside-in direction so as to blow the garbage in the first suction chamber 3 and below the first suction chamber 3 toward the suction port 2 or the second suction chamber 4 to increase the time during which the garbage is within the suction range of the suction port 2, thereby increasing the probability that the garbage is sucked by the suction port 2.
Alternatively, the air duct 6 is inclined at an angle of 5 ° to 40 ° with respect to the horizontal direction. Optionally, the air duct is inclined at an angle of 5 ° to 40 ° with respect to the forward direction of the cleaning vehicle.
The air duct 6 is a plurality of air ducts arranged along the advancing direction of the cleaning vehicle, and the flow guiding component 5 is arranged in front of the air duct 6 closest to the suction port 2 and behind the suction port 2.
Fig. 7 shows a schematic view of a cross section of the air duct 6 of the present embodiment, the cleaning vehicle suction nozzle further comprising an adjusting member 9 for adjusting the flow area of the air duct 6. As shown in fig. 3, the cleaning vehicle suction nozzle further includes a controller 10, wherein the controller 10 is used for controlling the adjusting component according to the speed of the cleaning vehicle, reducing the flow area of the air duct when the speed of the cleaning vehicle is increased, and increasing the flow area of the air duct when the speed of the cleaning vehicle is reduced.
