The suction nozzle comprises a suction nozzle body, the suction nozzle cavity arranged on the suction nozzle body, the suction nozzle front baffle arranged in the suction nozzle cavity, and the feed inlet adjusting device for the suction nozzle. According to the feed inlet adjusting device for a suction nozzle and the suction nozzle thereof, the bent state of the suction nozzle front baffle under the action of negative pressure is controlled to adjust the feed inlet area of the suction nozzle so as to enable the feed inlet to adapt to different working conditions.
Description
Technical field
The present invention is mainly concerned with the road-cleaning apparatus field, refers in particular to a kind of suction nozzle for road-cleaning.
Background technology
Suction nozzle, be widely used on the different kinds of roads cleaning equipment.As shown in Figure 1, take sweeping machine as example, the suction nozzle that existing sweeping machine uses, its principle is all: the work of driven by engine blower fan, in the interior formation negative pressure of suction nozzle inner chamber 2, cause suction nozzle front apron 1(to be generally rubber baffle) inside bending, cause the front breach of the anterior formation of suction nozzle; And rubbish can enter into suction nozzle inner chamber 2 by above-mentioned front breach under the drive of air-flow.Therefore, the size of breach before suction nozzle, just determined the negative pressure of suction nozzle inner chamber 2, also directly has influence on the capacity gauge of rubbish.
In said structure, under and prerequisite that the air-flow transfer passage is constant constant at rotation speed of fan, the air quantity passed through in suction nozzle inner chamber 2 is also fixed, and this just causes:
1,, for small garbage (as the fine sand class), the negative pressure owing to can't improving by the area that reduces front breach suction nozzle inner chamber 2, realize the lifting of suction, just there will be leaving over of rubbish.
2, for the rubbish (as leaf and paper scrap) of light thing class, because its volume ratio is larger, thereby also can't enter in suction nozzle inner chamber 2, and, before being deposited in suction nozzle front apron 1, leaving over of rubbish not only occur, the continuation cleaning of returning rubbish brings impact.
And when the sweeping machine operation, often can run into various road surfaces operating mode, as old and useless newspaper a large amount of on fine sand dust road surface, autumn a large amount of dried leaves and square etc.If use above-mentioned existing structure, complete the operation of above-mentioned operating mode, just the essential suction nozzle front apron 1 of changing, bring certain waste in man-hour thus, also increased tractor driver's labour intensity, thereby be unpractical in real work, and be impossible.And, often needing change rubber baffle or adjust continually the suction nozzle angle, workload is large, and effect also is not easy to control.
Summary of the invention
The technical problem to be solved in the present invention just is: the technical problem existed for prior art, the invention provides a kind of can be by controlling suction nozzle front apron case of bending and then adjust feed inlet adjusting device and the suction nozzle thereof for suction nozzle of suction nozzle charging aperture area under suction function.
For solving the problems of the technologies described above, the present invention by the following technical solutions:
A kind of suction nozzle feed inlet adjusting device, comprise for close suction nozzle inner chamber on the suction nozzle front apron, simultaneously contacting the opening coordinated with breach size before the control suction nozzle and control liner plate.
As a further improvement on the present invention:
Described opening is controlled liner plate and is connected with a rotation Control Component, and described rotation Control Component comprises axis of rotation and driving mechanism, and described opening is controlled liner plate and is installed on axis of rotation, and described axis of rotation is connected with the drive end of driving mechanism.
Described driving mechanism comprises actuator, swing arm and the push rod that is used for doing stretching motion, and described push rod is connected in the drive end of actuator, and an end of described swing arm is connected with push rod, and the other end of described swing arm is connected with axis of rotation.
The present invention further provides a kind of suction nozzle, comprise nozzle body, described nozzle body is provided with the suction nozzle inner chamber, and described suction nozzle inner chamber is provided with the suction nozzle front apron; Also comprise above-mentioned suction nozzle feed inlet adjusting device.
Compared with prior art, the invention has the advantages that:
1, feed inlet adjusting device and suction nozzle thereof for suction nozzle of the present invention, control by being arranged at the opening that simultaneously contacts cooperation near the suction nozzle inner chamber on the suction nozzle front apron size that liner plate is controlled breach before suction nozzle, and then adjustment suction nozzle charging aperture area, realized by changing the suction nozzle front apron, just not adjusting at any time the charging aperture area, total is very simple, easy and simple to handle.
2, feed inlet adjusting device and suction nozzle thereof for suction nozzle of the present invention, further adopt the mode of electronic control to adjust in real time the position that opening is controlled liner plate, and then the adjustment opening is controlled the contact point of liner plate and suction nozzle front apron, the adjustment of breach aperture before realizing, the whole driver's cabin that operates in just can complete, and operates very easy.

The specific embodiment
Below with reference to Figure of description and specific embodiment, the present invention is described in further details.
As shown in Figures 2 and 3, suction nozzle feed inlet adjusting device of the present invention, comprise for close suction nozzle inner chamber 2 one sides on suction nozzle front apron 1, contacting the opening coordinated with breach size before the control suction nozzle and control liner plate 3.This opening is controlled non-working surface one side that liner plate 3 is positioned at suction nozzle front apron 1, be used for contacting and push against suction nozzle front apron 1, while curving inwardly distortion under suction function when suction nozzle front apron 1, play the effect of fulcrum, and then allow suction nozzle front apron 1 bend to according to actual needs suitable position, form the front breach of suitable aperture, to be applicable to the actual demand under different operating modes.Opening is controlled liner plate 3 and can be fixed by the assembling mode of adjustable position, then by artificial mode, adjusts; Also can directly with a driven unit, be connected, by driven unit, with motion, adjust the contact point that opening is controlled liner plate 3 and suction nozzle front apron 1, and then control the aperture of front breach.
