Specific embodiment
As shown, a kind of suction inlet 1 with resetting apparatus, comprising: suction inlet 1, buffer resetting device 2, sealing are slow
Flushing device 3.
The suction inlet 1 is made of upper and lower two parts, and top is cylindrical body, and lower part is cuboid, by steel plate welding
At the negative pressure that inside has road sweeper fan to generate has for mobile castor, and the suction inlet 1, which is mounted on, cleans vehicle bottom
Portion, with vehicle driving, 1 lower part rearward edges of suction inlet are equipped with axle sleeve 11.
The buffer resetting device 2 includes upper interconnecting piece 21, gas spring 22, lower interconnecting piece 23；The gas spring 22 has
Retractility；Described 22 one end of gas spring is connected by screw thread with upper interconnecting piece 21, and 22 other end of gas spring passes through screw thread and lower company
Socket part 23 is connected, and passes through the length of the rotation adjustable buffer resetting device 2 of screw thread by upper interconnecting piece 21 and lower interconnecting piece 23,
The mismachining tolerance in production process is eliminated, the convenience in installation process is increased；The upper interconnecting piece 21 passes through pin shaft and dust suction
1 top of mouth is hinged and connected;The lower interconnecting piece 23 is hinged and connected by pin shaft with buffer resetting device 2；The upper interconnecting piece
21, lower interconnecting piece 23 can be rotated around pin shaft.
The sealing buffer unit 3 be mounted on suction inlet relative to sweeping machine move forward the vertical rear in direction that
On face comprising rubber bracket 31, rubber fastening bolt 32, suction inlet rubber 33.31 material of rubber bracket is steel plate, is led to
The mode for crossing punching press or bending processes l-shaped section, guarantees to reduce material thickness while structural strength；The rubber bracket
31 tops have been welded with rubber support rotating shaft, and rubber bracket 31 is mounted on axle sleeve 11 by rubber support rotating shaft, sealing
Buffer unit 3 can be rotated around axle sleeve 11；The suction inlet rubber 33 is mounted on rubber bracket 31 by rubber fastening bolt 32
And ground is extended downward into, just cover the slotted section on suction inlet shell and ground, the size and suction of suction inlet rubber 33
Long portion's size of 1 lower part of dirt mouth is consistent, to increase the leakproofness in suction inlet 1.
When vacuum sweeper is walked, suction inlet rubber 33 generates different frictional force from the road surface of different road conditions or ground projection
And impact force, stripper rubber is acted on by impact force drives axle sleeve 11 of the rubber bracket 31 on suction inlet 1 to rotate upwards, gas bullet
Spring 22 carries out corresponding automatic telescopic, the upper interconnecting piece 21 at 2 both ends of simultaneous buffering resetting apparatus according to the rotation of rubber bracket 31
Corresponding rotation is carried out around pin shaft with lower interconnecting piece 23 and plays buffer function, and postrotational suction inlet rubber 33 generates empty with ground
Gap, can be to avoid the abrasion and damage of the projection to suction inlet rubber 33 on ground；After shock, since frictional force and impact force subtract
Small or disappearance, 31 weight of rubber bracket turn downwards again due to the elastic reaction of gas spring 22 and the gravity of suction inlet rubber 33
It is dynamic, it is rotated down axle sleeve 11 of the suction inlet rubber 33 on suction inlet 1 and sets back again, cover suction inlet shell and ground
The slotted section in face guarantees the negative pressure in suction inlet 1 not to outward leakage.
