Summary of the invention
The present invention provides a kind of suction inlet with buffer resetting device for the prior art is insufficient and defect, can be with So that suction inlet rubber is avoided shock and abrasion that ground protrudes above object to suction inlet rubber, extend suction inlet rubber service life, Save human cost and material cost.
The present invention is achieved through the following technical solutions, a kind of suction inlet with buffer resetting device, comprising: the One component, second component, third member, the second component include elastic element, and one end of the second component is flexibly connected On the first component, the other end of the second component is movably connected in third member, and the second component is to third member With support force, the power being subject to for buffering third member, told second component can be stretched with third member and make Three parts reset, and the third member is flexibly connected with the first component, and a part of the third member covers the first component A part.
Specifically: a kind of suction inlet with buffer resetting device, comprising: suction inlet, buffer resetting device, sealing are slow Flushing device.
The suction inlet is made of upper and lower two parts, and top is cylindrical body, and lower part is cuboid, is welded by steel plate, The negative pressure that inside has road sweeper fan to generate has for mobile castor, and the suction inlet is mounted on cleaning vehicle bottom, with Vehicle driving, suction inlet lower part are equipped with sealing buffer unit interconnecting piece.
The buffer resetting device includes upper interconnecting piece, telescoping mechanism, lower interconnecting piece;The telescoping mechanism has flexible Property, it can be wire spring, gas spring, hydraulic spring grease cup, preferably gas spring;The upper interconnecting piece, lower interconnecting piece pass through screw thread The both ends of telescoping mechanism are connected to, by the length for rotating the adjustable buffer resetting device of screw thread;The buffer resetting device Upper interconnecting piece connect with suction inlet top movable, the lower interconnecting piece of the buffer resetting device and sealing buffer unit activity connect It connects, interconnecting piece may be rotated.
The sealing buffer unit includes rubber bracket, rubber retention mechanism, suction inlet rubber;The rubber bracket is cut Face is L-type, and there are two bindiny mechanisms for installation, and one is flexibly connected with suction inlet, another is flexibly connected with buffer resetting device; The suction inlet rubber is mounted on rubber bracket by rubber retention mechanism and extends downward into ground, the ruler of suction inlet rubber It is very little consistent with suction inlet lower dimension, to increase the leakproofness in suction inlet.
When vacuum sweeper is walked, suction inlet rubber and the road surface of different conditions or ground projection generate different frictional force and Impact force, sealing buffer unit top are flexibly connected by rotary shaft with suction inlet, can make to seal buffer unit around rotary shaft Rotary moveable is carried out, postrotational sealing buffer unit can avoid damage of the projection on ground to suction inlet rubber;Buffering Resetting apparatus frictional force according to suffered by sealing buffer unit and impact force carry out corresponding automatic telescopic, while passing through its both ends Bindiny mechanism correspondingly rotated buffer function played to suction inlet rubber.Buffer resetting device can be by rotating and stretching Contracting makes to be rushed open postrotational sealing buffer unit to set back again, and the negative pressure in guarantee suction inlet is in stable state.

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.
