1, for small garbage (like the fine sand class), owing to can't improve the negative pressure of suction nozzle inner chamber 2, realize the lifting of suction through the area of breach before reducing, leaving over of rubbish will appear.
2, for the rubbish (like leaf and paper scrap) of light thing class, because its volume ratio is bigger, thereby also can't get in the 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 influence.
And the sweeping machine operation time, run into various road surfaces operating mode through regular meeting, like old and useless newspaper a large amount of on fine sand dust road surface, autumn a large amount of dried leaves and the square etc.If use above-mentioned existing structure, accomplish the operation of above-mentioned operating mode, the just essential suction nozzle front apron 1 of changing brings certain waste in man-hour thus, has also increased tractor driver's labour intensity, thereby has been unpractical in real work, and be impossible.And, often needing to change rubber baffle or adjust the suction nozzle angle continually, workload is big, and effect also is not easy control.
The utility model content
The technical problem that the utility model will solve just is: to the technical problem that prior art exists, the utility model provides a kind of suction nozzle that can be through control suction nozzle front apron case of bending and then adjustment suction nozzle charging aperture area under suction function with charging aperture adjusting device and suction nozzle thereof.
For solving the problems of the technologies described above, the utility model adopts following technical scheme:
A kind of suction nozzle is used the charging aperture adjusting device, comprise be used for the suction nozzle front apron near suction nozzle inner chamber one side contact matching with the control suction nozzle before the opening control liner plate of breach size.
Further improvement as the utility model:
Said opening control liner plate links to each other with a Spin Control assembly, and said Spin Control assembly comprises axis of rotation and driving mechanism, and said opening control liner plate is installed on the axis of rotation, and said axis of rotation links to each other with the drive end of driving mechanism.
Said driving mechanism comprises actuator, swing arm and the push rod that is used for doing stretching motion, and said push rod is connected in the drive end of actuator, and an end of said swing arm links to each other with push rod, and the other end of said swing arm is connected with axis of rotation.
The utility model further provides a kind of suction nozzle, comprises nozzle body, and said nozzle body is provided with the suction nozzle inner chamber, and said suction nozzle inner chamber is provided with the suction nozzle front apron; Comprise that also above-mentioned suction nozzle uses the charging aperture adjusting device.
Compared with prior art, the advantage of the utility model is:
1, the suction nozzle of the utility model is with charging aperture adjusting device and suction nozzle thereof; Through be arranged at the suction nozzle front apron on control the size of breach before the suction nozzle near the opening control liner plate of suction nozzle inner chamber one side contact matching; And then adjustment suction nozzle charging aperture area; Realized just not adjusting the charging aperture area at any time through changing the suction nozzle front apron, total is very simple, easy and simple to handle.
2, the suction nozzle of the utility model is with charging aperture adjusting device and suction nozzle thereof; Further adopt the mode of electronic control to come the position of adjustment opening control liner plate in real time; And then the contact point of adjustment opening control liner plate and suction nozzle front apron; The adjustment of breach aperture before realizing, whole operation just can be accomplished at driver's cabin, and operation is very easy.

The specific embodiment
Below will combine Figure of description and specific embodiment that the utility model is explained further details.
As shown in Figures 2 and 3, the suction nozzle of the utility model is used the charging aperture adjusting device, comprise be used for suction nozzle front apron 1 near suction nozzle inner chamber 2 one side contact matching with the control suction nozzle before the opening control liner plate 3 of breach size.This opening control liner plate 3 is positioned at non-working surface one side of suction nozzle front apron 1; Be used for contacting and pushing against suction nozzle front apron 1; When suction nozzle front apron 1 curves inwardly distortion under suction function, play the effect of fulcrum, and then let suction nozzle front apron 1 bend to suitable position according to actual needs; Form the preceding breach of suitable aperture, to be fit to the actual demand under the different operating modes.Opening control liner plate 3 can be fixed through the fit of adjustable position, adjusts through the mode of manual work then; Also can directly link to each other, motion, the contact point of adjustment opening control liner plate 3 and suction nozzle front apron 1, and then the aperture of the preceding breach of control through the driven unit band with a driven unit.
