Problems solved by technology
[0004] 1. For small garbage (such as fine sand), since it is impossible to reduce the area of the front gap to increase the negative pressure in the inner cavity 2 of the suction nozzle to achieve an increase in suction, garbage will be left behind
[0005] 2. For light garbage (such as leaves and paper scraps), due to its relatively large volume, it cannot enter the inner cavity 2 of the suction nozzle, and accumulates in front of the front baffle 1 of the suction nozzle, not only leaving garbage , It also affects the continuous cleaning of garbage
If the above-mentioned existing structure is used, to complete the operation of the above-mentioned working conditions, it is necessary to replace the front baffle plate 1 of the suction nozzle, which brings a certain waste of working hours and increases the labor intensity of the operator. Therefore, in actual work is unrealistic and impossible
Moreover, it is often necessary to replace the rubber baffle or frequently adjust the angle of the suction nozzle, the workload is heavy, and the effect is not easy to control

Embodiment Construction
[0022] The present invention will be further described in detail below in conjunction with the accompanying drawings and specific embodiments.
[0023] Such as figure 2 and image 3 As shown, the feed opening adjustment device for suction nozzles of the present invention includes an opening control liner 3 used to contact and cooperate with the side of the suction nozzle front baffle 1 close to the suction nozzle inner cavity 2 to control the size of the gap in front of the suction nozzles. The opening control liner 3 is located on the non-working side of the nozzle front baffle 1, and is used to contact and press against the suction nozzle front baffle 1. When the suction nozzle front baffle 1 bends inwards and deforms under negative pressure , which acts as a fulcrum, and then allows the nozzle front baffle 1 to bend to a suitable position according to actual needs, forming a front gap with a suitable opening, so as to meet the actual needs under different working conditio...

The invention discloses a feed inlet adjusting device for a suction nozzle and the suction nozzle. The adjusting device comprises an opening control lining plate which is used to be in contact fit with one face close to a suction nozzle cavity, on a suction nozzle front baffle so as to control the size of a front notch of the suction nozzle. 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 [0001] The invention mainly relates to the field of road cleaning equipment, in particular to a suction nozzle for road cleaning. Background technique [0002] Suction nozzles are widely used in various road cleaning equipment. Such as figure 1 As shown, taking the road sweeper as an example, the principle of the suction nozzle used by the existing road sweeper is: the engine drives the fan to work, and a negative pressure is formed in the inner cavity 2 of the suction nozzle, causing the front baffle 1 of the suction nozzle ( Generally, it is a rubber baffle) deformed and bent inward, resulting in a front gap at the front of the suction nozzle; and the garbage will enter the inner cavity 2 of the suction nozzle through the above-mentioned front gap under the drive of the airflow. Therefore, the size of the gap in front of the suction nozzle determines the negative pressure of the suction nozzle inner cavity 2, and also directly affects the collection capac...
