In the present invention, housing encloses the chamber 10 to form lower openings.Suction picks up chamber in housing, and it both can be chamber The entirety of room 10 a, or part for chamber 10.In order that the volume size that chamber is picked up in suction can change, in the present invention, At least part of housing could be arranged to movably；And/or, cavity body structure 1 can also include separation structure, and separation structure is set It is placed in chamber 10 and chamber 10 is separated to form suction picks up chamber by being contacted with housing, separation structure is set to movably.

As a kind of embodiment therein, separation structure can be not provided with, and at least part of housing is set to can Mobile.In this embodiment, the entirety for picking up that chamber is chamber 10 is inhaled, i.e. suction picks up chamber for chamber 10, housing formation, which is inhaled, picks up chamber Cavity wall, therefore, the componental movement that housing can be moved, you can change the volume inhaled and pick up chamber.For example, side plate and/or the top of housing Plate 11 could be arranged to movably.Wherein, when the side plate of housing is set to moveable, chamber can be picked up by changing to inhale Left and right width and/or anterior-posterior length inhale the volume size for picking up chamber to change；And when the top plate 11 of housing is set to moveable, It can then be inhaled by change and pick up the height of chamber to change the volume size that chamber is picked up in suction.Due to separation structure need not be increased, therefore, In the embodiment, the structure member included by cavity body structure 1 is less, and the structure of suction nozzle of sweeping car is relatively simple.

As another embodiment therein, at least part of housing can not also be set to movably, and only Separation structure is set, and separation structure is set to movably.In this case, inhale and pick up the entirety that chamber is no longer chamber 10, But a part for chamber 10, separation structure and housing enclose the cavity wall to be formed and inhale and pick up chamber jointly, chamber is picked up in separation structure formation suction Cavity wall a part, therefore, separation structure motion can change to inhale and pick up the volume size of chamber.In this embodiment, due to Separation structure motion is only needed to can be achieved to pick up the change of cavity volume size to inhaling, and need not be set to can for the arbitrary portion of housing Mobile, therefore, structure is more simple, and regulation process is more easily realized, more flexible can easily change sweeping machine and inhale The suction size of mouth.Moreover, in this embodiment, can still not can be movable relatively using existing each several part due to housing Structure type (such as welded type integrative-structure), it is therefore not necessary to which the structure to housing carries out more change, is easily realized, and Cost is relatively low.

As another embodiment therein, moveable separation structure can also be both set up, and housing is set to It is at least partly moveable, in order to pick up the entirety that chamber is no longer chamber 10 but in the case of a part for chamber 10 in suction, Can simultaneously by make separation structure move and make the componental movement that can be moved of housing come change inhale pick up chamber volume it is big It is small, realize and the more efficient regulation of cavity volume is picked up to suction.

In the present invention, side plate is the plate to form the side wall of chamber 10.Side plate can include front apron 12, rear baffle 15, a left side Side plate 13 and right plate 14, now, the section of chamber 10 can with rectangular, side plate is removable can be front apron 12, rear baffle 15, At least one in left plate 13 and right plate 14 may move；Or, when chamber 10 is cylindrical chamber, side plate can also be wrapped Include front apron 12 and circular arc plate, it can be that at least one in front apron 12 and circular arc plate may move that side plate is removable；When So, chamber 10 can be with the other shapes such as triangular in shape, and correspondingly, side plate can also be using other structure types.But can be with Understand, no matter which kind of specific structure type chamber 10 uses in which kind of shape, side plate, and rubbish enters for convenience, and side plate leads to Often include rubbish and enter baffle plate, and rubbish enters baffle plate is usually arranged as elasticity and/or lower end and picks up intracavitary to suction and roll tiltedly, makes Obtaining rubbish can pick up in chamber via rubbish into baffle plate into suction, for example, when chamber 10 is rectangular cavity, can be such as prior art In it is the same, front apron 12 is set to rubbish and enters baffle plate, i.e. be that front apron 12 is set to elasticity and/or make front apron 12 Lower end to suction pick up intracavitary roll it is oblique.

In addition, in the present invention, when setting up separation structure in the housing, separation structure could be arranged to move up and down And chamber 10 is divided into by first chamber above and underlying second chamber by the side plane contact with housing Room.In this case, second chamber is that chamber is picked up in suction, that is, inhales the low portion for picking up that chamber is chamber 10, and chamber is picked up in separation structure formation suction Roof, pick up the height (size of above-below direction) of chamber because separation structure moves up and down to change to inhale, therefore, it can change Inhale the volume for picking up chamber.Certainly, alternatively, separation structure is it can also be provided that can moving left and right and separate chamber 10 The two chambers being distributed for left and right, two chambers form two less suctions and pick up chamber respectively, can pass through movement in this case Separation structure changes two and inhales the length (size of left and right directions) for picking up chamber, and then the regulation for picking up cavity volume is inhaled in realization to two, So set and be advantageous in that, left and right directions rubbish can be better adapted to and be distributed different road conditions, such as usual road edge phase More for rubbish on the inside of road, based on this suction nozzle of sweeping car with the separation structure that can be moved left and right, sweeping machine is in work , can be by moving left and right separation structure during work, the small volume of chamber is picked up in suctions that make rubbish be distributed more side, satisfaction compared with Requirement is picked up in the suction of many rubbish, while the volume that chamber is picked up in the suction for making rubbish be distributed less side is larger, the suction for meeting less rubbish is picked up It is required that, so as to realize more flexible and efficient road cleaning operation process；Or, separation structure may be arranged as can be front and rear Mobile and distribution before and after chamber 10 is divided into two chambers, can be located at front for example, inhaling and picking up chamber for chamber 10 The rear wall for picking up chamber is inhaled in chamber, separation structure formation, can so enable to change by mobile separation structure and inhale the width for picking up chamber Spend (size of fore-and-aft direction), and then realize the regulation that cavity volume is picked up to suction.Wherein, relative to two kinds alternatives, will separate Structure setting is moving up and down and chamber 10 is separated to form to the two chambers being distributed up and down using separation structure, is not only tied Structure is simpler, it is easier to realize, its benefit is also resided in, and can make it that it is still chamber to inhale the opening for being connected with ground for picking up chamber The whole lower openings of room 10, inhale and pick up chamber to be used for the aperture area that is connected with ground larger, so as to realize in a big way Road surface cleaning, sweeping efficiency is higher.

Include the separation structure and separation structure that chamber 10 is divided into the two chambers being distributed up and down based on cavity body structure 1 Embodiment moving up and down, separation structure of the invention can include demarcation strip 17, and separation structure is being moved up and down During with side plate keep gas-tight contact.For example, when side plate includes front apron 12, rear baffle 15, left plate 13 and right plate When 14, separation structure can keep gas-tight contact with front apron 12, rear baffle 15, left plate 13 and right plate 14.Due to Chamber 10 is divided into the case that underlying suction picks up chamber by separation structure and side plane contact, suction pick up chamber be by separation structure with Side plate encloses what is formed, therefore, separation structure is kept gas-tight contact with side plate during moving up and down, contributes to Regulation suction more effectively improves the air-tightness inhaled and pick up chamber during picking up cavity volume size, it is to avoid gas is leaked.

In order to realize the gas-tight contact of separation structure and side plate, directly demarcation strip 17 can be set to it is telescopic, So that itself anteroposterior dimension of demarcation strip 17 (width) and/or side-to-side dimensions (length) are adjustable, so in the process moved up and down In, demarcation strip 17 can change the size of itself by stretching, and then compensate move up and down during demarcation strip 17 and side plate Between gap variable quantity.For example, demarcation strip 17 could be arranged to it is front and rear telescopic so that demarcation strip 17 can be by changing Become the anteroposterior dimension of itself compensate move up and down during gap between demarcation strip 17 and front apron 12 and/or rear baffle 15 Variable quantity, realizes that separation structure keeps the purpose of gas-tight contact with front apron 12 and/or rear baffle 15.For another example demarcation strip 17 it can also be provided that left and right is telescopic so that demarcation strip 17 can be moved down by changing the side-to-side dimensions of itself on compensating Gap variable quantity during dynamic between demarcation strip 17 and left plate 13 and/or right plate 14, realizes separation structure and left plate 13 and/or right plate 14 keep gas-tight contact purpose.

Or, in order to realize the gas-tight contact of separation structure and side plate, separation structure can also be set to also include Adjustment structure is contacted, demarcation strip 17 is contacted by contacting adjustment structure with least part of side plate, also, in the mistake moved up and down Cheng Zhong, contact adjustment structure can make separation structure and side plate at least by changing the distance between itself and demarcation strip 17 Part keeps gas-tight contact.By setting contact adjustment structure so that the physical dimension of itself of demarcation strip 17 can be without hair Changing can keep gas-tight contact with least part of side plate, realize simpler convenience, and sealing effectiveness is more preferable.

And in order that contact adjustment structure can change itself distance between demarcation strip 17 during moving up and down, In the present invention, contact adjustment structure can be relatively movably connected with demarcation strip 17, and/or, contact adjustment structure can be with It can be deformed including elastic construction and elastic construction.Wherein, when contact adjustment structure can be relatively movably connected with demarcation strip 17 When, during moving up and down, with the increase and decrease of distance between demarcation strip 17 and side plate, contact adjustment structure can with demarcation strip 17 To be located remotely from each other or close to each other, at least part gap variable quantity between demarcation strip 17 and side plate is compensated；And work as and connect Touch adjustment structure include can deform elastic construction when, due to during moving up and down elastic construction deformation can with point The change of distance between dividing plate 17 and side plate and change, thus, it is also possible to at least portion between demarcation strip 17 and side plate Subdivided gap variable quantity is compensated.So, by the way that contact adjustment structure can be relatively movably connected with demarcation strip 17, and/or, Contact adjustment structure is included the elastic construction that can be deformed, can to contact adjustment structure energy during moving up and down It is enough to keep at least part of gas-tight contact with side plate by changing the distance between itself and demarcation strip 17.

As a kind of embodiment of present invention contact adjustment structure, it is single that contact adjustment structure can include contact regulation Member, contact adjustment unit includes sealing plate 18, and demarcation strip 17 is contacted by sealing plate 18 with least part of side plate, and sealing plate 18 can relatively movably be connected with demarcation strip 17.In this embodiment, sealing plate 18 can relatively movably connect with demarcation strip 17 Connect, therefore, during moving up and down, sealing plate 18 by being moved relative to demarcation strip 17 with that can compensate demarcation strip 17 The variable quantity in gap between side plate so that demarcation strip 17 can keep gas-tight contact by sealing plate 18 and side plate all the time, Prevent gas from leaking.It can realize and can relatively move by the mode such as socket or slide rail connection between sealing plate 18 and demarcation strip 17 Ground is connected.

A kind of as above-mentioned contact adjustment unit improves embodiment, sealing plate 18 can also be further arranged into bullet Property sealing plate.Based on this, during moving up and down, sealing plate 18 can not only be mended by remote or close demarcation strip 17 The variable quantity in gap between demarcation strip 17 and side plate is repaid, can also be further compensate for separating using the deformation of itself of sealing plate 18 The variable quantity in gap between plate 17 and side plate so that sealing plate 18 can more closely with side plane contact, further improve suction pick up The air-tightness of chamber.It can be seen that, in this embodiment, contact adjustment unit passes through the relative shifting of sealing plate 18 and demarcation strip 17 simultaneously The deformation of dynamic and sealing plate 18 the distance between changes with demarcation strip 17, and sealing plate 18 plays aforementioned contact adjustment structure The effect of elastic construction.

As another improvement embodiment of above-mentioned contact adjustment unit, contact adjustment unit can also include elasticity Part, wherein, sealing plate 18 has slot, and demarcation strip 17 is removably inserted within slot；Elastic component is arranged in slot and supported and sets Between demarcation strip 17 and the bottom wall of slot.In the improvement embodiment, sealing plate 18 can be relatively movably with demarcation strip 17 Socket, and elastic component by changing deformation to apply to sealing plate 18 and demarcation strip 17 can make the two during moving up and down The active force of relative movement so that contact adjustment unit can simultaneously by the relative movement of sealing plate 18 and demarcation strip 17 and The deformation of elastic component the distance between changes with loading plate 34.It can be seen that, the elastic component in the embodiment plays aforementioned contact The effect of the elastic construction of adjustment structure.Elastic component structure type such as can use spring 19.

Due to as it was previously stated, rubbish included by side plate enters baffle plate generally has deformation and/or be obliquely installed, therefore, During moving up and down, demarcation strip 17 enters the distance between baffle plate with rubbish to have greatly changed, and keep separating knot The difficulty of structure and rubbish into gas-tight contact between baffle plate is larger.So, in order to effectively prevent during moving up and down Because demarcation strip 17 can not enter baffle plate with rubbish contact and influence suction to pick up the air-tightness of chamber, foregoing side plate is used for and separation structure At least part of gas-tight contact enters baffle plate including rubbish, that is, in the present invention, it is preferred to, separation structure at least with rubbish Rubbish enters baffle plate and keeps gas-tight contact.Correspondingly, when setting contact adjustment structure, contact adjustment structure preferably at least includes First contact adjustment structure, the first contact adjustment structure is arranged at demarcation strip 17 and rubbish enters between baffle plate, for separating Structure makes separation structure enter gear with rubbish during moving up and down by changing the distance between itself and demarcation strip 17 Plate keeps gas-tight contact.First contact adjustment structure can use the structure of aforementioned contact adjustment unit, i.e. can be by one Aforementioned contact adjustment unit is arranged at demarcation strip 17 and rubbish enters between baffle plate, as the first contact adjustment structure so that the One contact adjustment structure can be by sealing plate 18 and demarcation strip 17 relative movement and/or elastic construction (sealing plate 18 and/or Elastic component) deformation change itself the distance between with demarcation strip 17, it is ensured that during moving up and down, demarcation strip 17 can All the time the gas-tight contact that baffle plate keeps good is entered by sealing plate 18 and rubbish, effectively prevents gas in separation structure and rubbish Reveal the contact position that rubbish enters baffle plate.

Further, due to keeping gas-tight contact with whole side plate during moving up and down when separation structure When, during moving up and down, chamber is picked up in suction to be had preferably all the time in each edge of separation structure and side plane contact Air-tightness, can more efficiently prevent from occurring gas leakage problem during cavity volume is picked up in regulation suction, contribute to further Improve suction of the suction nozzle of sweeping car to ground refuse and pick up effect, therefore, it is highly preferred that present invention contact adjustment structure is except that can wrap Include outside the first contact adjustment structure, can also include being arranged at demarcation strip 17 with side plate in addition to rubbish enters baffle plate Second contact adjustment structure between remainder etc. so that separation structure can be with whole side plate during moving up and down Keep gas-tight contact.For example, when side plate except including as rubbish enter baffle plate front apron 12 in addition to, in addition to after keep off When plate 15, left plate 13 and right plate 14, contact adjustment structure can not only include front end and the front for being arranged at demarcation strip 17 The first contact adjustment structure between plate 12, can also include second be arranged between the rear end of demarcation strip 17 and rear baffle 15 Contact adjustment unit, the 3rd be arranged between the left end of demarcation strip 17 and left plate 13 contact adjustment structure and are arranged at point The 4th between the right-hand member of dividing plate 17 and right plate 14 contacts adjustment structure, is respectively used to regulation and realizes separation structure and front apron 12nd, the gas-tight contact between rear baffle 15, left plate 13 and right plate 14.Certainly, the first contact adjustment structure, the second contact The structure of adjustment structure, the 3rd contact adjustment structure and the 4th contact adjustment structure can be with identical, can also be different.

In the present invention, demarcation strip 17 can be flat board, but it is highly preferred that demarcation strip 17 could be arranged to have to recessed Sunken recess.Due to being moved to during identical height and position, relative to the situation for flat board, the recess of demarcation strip 17 can be further Reduce the height inhaled and pick up chamber so that demarcation strip 17 can further reduce the volume inhaled and pick up chamber using the features of shape of itself, Therefore, demarcation strip 17 is set to recess by the present invention, can be more effective when demarcation strip 17 is moved to arbitrary height position Ground reduces the volume inhaled and pick up chamber, slows down the rate of decay inhaled and pick up intracavitary negative pressure, so that more effectively increase suction nozzle of sweeping car is to rubbish The suction of rubbish, improves refuse sweeping effect, improves refuse sweeping efficiency.

In addition, in order to realize that picking up cavity volume to suction automatically adjusts, suction nozzle of sweeping car of the invention, it can also include inhaling Pick up chamber governor motion, the suction pick up chamber governor motion be used for adjust suction pick up the volume size of chamber.Due to inhale pick up chamber governor motion can be with It is automatic to realize the regulation that cavity volume size is picked up to suction, suction size is automatically adjusted, without by manual adjustment, therefore, Ke Yigeng Easily and flexibly cavity volume size is picked up in cleaning process to suction according to actual condition to be adjusted, adjust the simpler height of process Effect, the function of suction nozzle of sweeping car is more perfect, and automaticity is higher.

Because rubbish is generally picked up in chamber by rubbish into baffle plate into suction, and rubbish into baffle plate be usually elastic gear Plate, its deflection can reflect the granular size of rubbish, i.e. rubbish enters baffle plate usually can be according to the rubbish that chamber is picked up into suction Size change the size of self-deformation amount, therefore, in order to more easily realize detection to rubbish size, and further letter Change structure, detection means 4 of the invention could be arranged to detect entrance by detecting rubbish into the size of baffle plate deflection The size of the rubbish of chamber 10, so simpler convenience of detection process, testing result is also more accurate.Certainly, detection means 4 Other structures form can also be used, for example, detection means 4 may be arranged as including vision inspection apparatus, view-based access control model inspection Survey technology is detected to garbage bulk size.

The present invention is described further with reference to the embodiment shown in Fig. 1-7.

As shown in figs. 1-7, in this embodiment, suction nozzle of sweeping car picks up intonation section dress including cavity body structure 1, suction tube 2 and suction Put, wherein：Cavity body structure 1 includes housing, housing and encloses the chamber 10 to be formed, rear cowl 16, separation structure and separation structure The suction to be formed is enclosed with housing and picks up chamber；Suction tube 2 can up or down be arranged on housing and pick up chamber with suction and connect, so that on ground Rubbish chamber can be picked up via suction into suction tube 2；Inhale and pick up cavity adjusting device then for the size according to pavement garbage come automatic The volume size for picking up chamber is inhaled in regulation, is adapted with automatically adjusting suction size with granulated garbage size, enhancing uses flexibility, changes Kind rubbish, which is inhaled, picks up effect, improves rubbish suction and picks up efficiency.

As depicted in figs. 1 and 2, in this embodiment, housing include top plate 11 and side plate, side plate include front apron 12, after Baffle plate 15, left plate 13, right plate 14, top plate 11, front apron 12, rear baffle 15, left plate 13 and right plate 14 enclose to be formed Chamber 10, chamber 10 has lower openings so that chamber 10 and ground gas connection, is easy to ground refuse via under chamber 10 Portion's opening enters in suction nozzle of sweeping car.Wherein, front apron 12 enters baffle plate as rubbish.As shown in Fig. 1, Fig. 3 and Fig. 6, the reality Apply example front apron 12 be elastic baffle (such as rubber slab), with certain elasticity, can according to the granular size of rubbish come Change the deflection of itself, granulated garbage is bigger, and the deflection of front apron 12 is bigger；Moreover, the lower end of front apron 12 relative to The upper end of front apron 12 is obliquely installed towards the inner side of chamber 10.So, when suction is scavenged, front apron 12 can be to the inner side of chamber 10 Bend, gap of the rubbish between the lower end of front apron 12 and ground is picked up into suction in chamber.

From Fig. 3 and Fig. 6, rear cowl 16 is arranged at the rear side of rear baffle 15, itself and rear baffle 15, left plate 13, right side Plate 14 encloses to form spray chamber.Spray chamber is located at the rear side of chamber 10, and is connected with chamber 10.Spray can be set inside spray chamber Water bar (not shown).By setting spray chamber and spray boom, it is possible to use the water column that spray boom sprays will be located at chamber 10 The ground refuse at rear is rushed to the lower section of chamber 10, consequently facilitating this part rubbish positioned at the rear of chamber 10 enters via chamber 10 In suction tube 2, realize that the suction to wider rubbish is picked up.

Separation structure is actively arranged in chamber 10, and it is applied not only to contact with housing, and chamber 10 is separated to form into position Chamber is picked up in the suction in housing and for the part of chamber 10, is additionally operable to change the volume inhaled and pick up chamber by the movement in chamber 10 Size.From Fig. 1-7, in this embodiment, separation structure is arranged substantially horizontally in chamber 10, its side plate with housing Contact, chamber 10 is separated to form first chamber and underlying second chamber above so that second chamber is formed Chamber is picked up in suction, and the roof for picking up chamber is inhaled in separation structure formation；Moreover, separation structure can be arranged in chamber 10 up or down so that The height inhaled and pick up chamber can be changed by moving up and down separation structure, change the volume size inhaled and pick up chamber, realized to sweeping machine Suction nozzle applies the regulation of suction size.

Further, in order to realize that picking up cavity volume to suction automatically adjusts, and in order to realize the size according to pavement garbage Carry out flexible modulation and inhale the purpose for picking up cavity volume size, in this embodiment, suction nozzle of sweeping car picks up cavity adjusting device including suction, and should Suction picks up cavity adjusting device and picks up chamber governor motion including detection means 4 and suction.Wherein, detection means 4 is used to detect pavement garbage Size；Chamber governor motion is picked up in suction to be used to drive separation structure to move up and down according to the testing result of detection means 4, is divided by changing The volume size inhaled and pick up chamber is adjusted every the height of structure, suction is picked up negative pressure distribution and the actual need of different size rubbish of intracavitary Ask adaptable.

The detection means 4 of the embodiment realizes the inspection to rubbish size by detecting the deflection size of front apron 12 Survey.From Fig. 3 and Fig. 6, in this embodiment, detection means 4 is arranged on front apron 12, and it can be strain transducer, In real time detection front apron 12 due to ground refuse by and the bending deformation quantity that produces, and then detect that the volume of ground refuse is big It is small, and testing result is fed back into suction pick up chamber governor motion, in order to inhale ten chamber governor motions according to the size of ground refuse come Driving separation structure is moved up and down.

Wherein, as in Figure 2-4, when detection means 4, which detects front apron 12, produces less deflection, granulated garbage Smaller, testing result is fed back to suction and picks up chamber governor motion by detection means 4, and it is downward to pick up chamber governor motion driving separation structure by suction It is mobile, reduce the height of separation structure, reduce the volume inhaled and pick up chamber, slow down the speed of negative pressure decay, suction is picked up intracavitary has foot Enough suction can be by the less rubbish intake chamber 10 such as dust and suction tube 2；And when detect front apron 12 produce it is larger Deflection when, then granulated garbage is larger, and testing result is fed back to suction and picks up chamber governor motion by detection means 4, and intonation is picked up by suction Section mechanism driving separation structure is moved up, and increases the height of separation structure, and increase inhales the volume for picking up chamber, enables suction nozzle of sweeping car It is enough to suck larger rubbish.

It can be seen that, the embodiment can make suction nozzle of sweeping car more flexible by setting detection means 4 and suction to pick up chamber governor motion Demand is picked up in the suction that ground adapts to different size rubbish, and the suction of abundance can be both provided for less rubbish, larger rubbish can be made again Rubbish thing is passed through, and suction picks up more efficient, and it is more preferable that effect is picked up in suction.

Chamber governor motion is picked up in the suction of the embodiment includes height regulation drive device 3, height regulation drive device 3 and cavity The separation structure drive connection of structure 1 simultaneously be used for drive separation structure to move up and down, with realize to suction pick up cavity volume size from Dynamic regulation.Specifically, from Fig. 1 and Fig. 2, height regulation drive device 3 includes actuating unit 31, lifting arm 32 and traction piece 33, wherein：The one ends wound of traction piece 33 is on lifting arm 32, and the other end of traction piece 33 is connected with separation structure, engine Structure 31 makes traction piece 33 drive separation structure to move up and down with the drive connection of lifting arm 32 and by driving lifting arm 32 to rotate. Based on this, start actuating unit 31, lifting arm 32 is rotated, control the folding and unfolding of traction piece 33, you can easily drive on separation structure Lower movement, also, change the rotation direction of lifting arm 32, you can change the folding and unfolding direction of traction piece 33, so as to change separation knot Structure moves up and down direction.Wherein, actuating unit 31 can be motor etc.；Traction piece 33 can be drag-line, cable or rope etc..

Suction tube 2 is used to connect the dustbin (not shown) inhaled and pick up chamber and sweeping machine, so as to pick up the ground of chamber into suction Rubbish can enter in dustbin via suction tube 2 to be stored.As shown in Figure 1, Figure 2 with shown in Fig. 5, in this embodiment, suction nozzle of sweeping car Including two suction tubes 2, two suction tubes 2 are no longer welded on housing, but can be arranged at up or down on housing, and two Individual suction tube 2 is carried on separation structure and can together moved up and down with separation structure.Specifically, each suction tube 2 is wrapped Cylinder and fountain head 21 are included, the upper end of cylinder is extend out to outside chamber 10 from top plate 11, the lower end of cylinder is then stretched into from top plate 11 The inside of chamber 10 is simultaneously fixedly connected with separation structure；The upper and lower ends of cylinder are open, cylinder by the opening positioned at lower end with Chamber connection is picked up in suction, while being connected by the opening positioned at upper end with dustbin, in order to which the rubbish that intracavitary is picked up into suction is conveyed To dustbin；Two fountain heads 21 are respectively arranged at the left and right sides of cylinder, for being sprayed water to inner barrel, it is to avoid suction tube 2 Inside produces dust raising phenomenon.

Because suction tube 2 can together be moved up and down with separation structure, therefore, the embodiment is by changing separation structure While highly picking up cavity volume size to change suction, the regulation to the height of suction tube 2 can also be realized in the lump, be conducive to making suction tube 2 Height also more adapted to actual condition demand.On the one hand, because the height of suction tube 2 also has one to the volume size that chamber is picked up in suction Fixed influence, the height of suction tube 2 is lower, and the volume that chamber is picked up in suction is smaller, and negative pressure decay is slower, and suction is bigger, therefore, the embodiment Suction tube 2 is set to what can together be moved up and down with separation structure, can be further enhanced to suction nozzle of sweeping car suction Regulation.On the other hand, because when the height of suction tube 2 is too small, the road clearance of suction tube 2 is too small, the stone that volume can be caused larger Piece wait particle not pass through, influence to pick up effect to the suction of larger rubbish, therefore, suction tube 2 is set to by the embodiment can With what is moved up and down together with separation structure, the height of suction tube 2 is adapted to the demand of different size rubbish for greater flexibility, may be used also Effectively to prevent from smoothly realizing that the suction to larger rubbish is picked up because suction tube 2 is highly too low, help further to improve suction and pick up Efficiency is picked up in effect and raising suction.Suction tube 2 is carried on separation structure by another further aspect, the embodiment, not only can be by opening Dynamic height adjusts drive device 3 to conveniently realize the regulation to the height of suction tube 2, is allowed to be adapted with actual condition demand, together When, due to the supporting role of separation structure, it is also possible that suction tube 2 can be moved up and down more smoothly, more steadily effectively Height to suction tube 2 is adjusted；Moreover, be also convenient for realizing to separation structure based on sustained height regulation drive device 3 and The synchronous driving of each suction tube 2, not only structure is simpler, between separation structure and suction tube 2 and between each suction tube 2 above and below Mobile synchronism is also more preferable.

As shown in Figure 2, in this embodiment, height regulation drive device 3 is directly connected by traction piece 33 with separation structure Connect, it is to be understood that, alternatively, the traction piece 33 of height regulation drive device 3 can also be connected on suction tube 2, led to Cross and be connected and be connected indirectly with separation structure with suction tube 2, so can also drive separation structure and suction tube 2 on move down It is dynamic.

In addition, it is necessary to which explanation, the annexation of suction tube 2, housing and separation structure is not limited to the embodiment Shown, for example, suction tube 2 still can also be fixedly installed on housing (for example, suction tube 2 can be still welded on top plate 11), and Separation structure can be connected (for example separation structure can be sheathed on the bottom of suction tube 2) with suction tube 2 up or down, so, though Right suction tube 2 can not together be moved up and down with separation structure, but because separation structure can still be moved up and down, therefore, can still be had The volume size for picking up chamber is inhaled in effect regulation.

Further, there is preferable air-tightness all the time during separation structure is moved up and down in order that inhaling and picking up chamber, From Fig. 1-7, the separation structure of the embodiment includes demarcation strip 17 and contact adjustment structure, and suction tube 2 is carried on demarcation strip 17 On, and demarcation strip 17 is by contacting adjustment structure and whole side plate gas-tight contact.Specifically, demarcation strip 17 is adjusted by contacting Structure keeps gas-tight contact with front apron 12, rear baffle 15, left plate 13 and right plate 14.More specifically, contact regulation Structure includes the first contact adjustment structure, the second contact adjustment structure, the 3rd contact adjustment structure and the 4th contact adjustment structure, Demarcation strip 17 is adjusted by the first contact adjustment structure, the second contact adjustment structure, the 3rd contact adjustment structure and the 4th contact Structure keeps gas-tight contact with front apron 12, rear baffle 15, left plate 13 and right plate 14 respectively.Based on this, adjusted in contact Under the adjustment effect of nodule structure, chamber is picked up in suction has good air-tightness all the time, effectively can prevent gas from leaking, suction is picked up chamber and exist Separation structure and suction tube 2 can provide the sufficient suction needed desired by corresponding operating mode when being moved to arbitrary height position, Realize that more efficient and more high-quality rubbish is inhaled and pick up process.

Wherein, the first contact adjustment structure is arranged between the front end of front apron 12 and demarcation strip 17, for by changing Itself distance between the front end of demarcation strip 17 along the longitudinal direction come adjust realize it is airtight between separation structure and front apron 12 Property contact.Because the front apron 12 of the embodiment as rubbish enters baffle plate, it is elastic baffle and its lower end into chamber 10 Side is obliquely installed, therefore, is driven in demarcation strip 17 during suction tube 2 moves up and down, the front end and front apron 2 of demarcation strip 17 it Between distance can have greatly changed, wherein, demarcation strip 17 drives suction tube 2 when moving up, and the front end of demarcation strip 17 is with before The distance between baffle plate 2 becomes big.Therefore, in order to more effectively keep the gas-tight contact between separation structure and front apron 12, As illustrated in figs. 2-7, the first contact adjustment structure of the embodiment includes sealing plate 18 and spring 19, wherein：Sealing plate 18 has Slot, specifically, sealing plate 18 is generally U-shaped in Fig. 4 and Fig. 7, and the front end of demarcation strip 17 can insert slot movably forward and backward In and contacted by sealing plate 18 with front apron 12；Spring 19 is arranged in slot and to the front end located at demarcation strip 17 and slot Bottom wall between.Based on this, during demarcation strip 17 drives suction tube 2 to move up and down, spring 19 can stretch, and change The deflection of itself, and the process stretched in spring 19, sealing plate can be passed through between sealing plate 18 and the front end of demarcation strip 17 Relatively movable and close to each other between 18 and demarcation strip 17 is located remotely from each other, and is compensated by sealing plate 18 and spring 19 point The distance between the front end of dividing plate 17 and front apron 2 variable quantity so that demarcation strip 17 can pass through sealing plate 18 and front all the time Plate 12 keeps gas-tight contact, effectively prevents gas from being revealed between the front end of demarcation strip 17 and front apron 12.

Wherein, from Fig. 2 and Fig. 4, when ground granulated garbage is smaller, the flexural deformation of front apron 12 is smaller, and height is adjusted Section drive device 3 transfers demarcation strip 17 and suction tube 2 to lower position, the distance between the front end of demarcation strip 17 and front apron 2 Diminish so that spring 19 is in compressive state, the front end of sealing plate 18 and demarcation strip 17 is close to each other, the front end of demarcation strip 17 leads to Cross sealing plate 18 and keep gas-tight contact with front apron 12；And from Fig. 5 and Fig. 7, when ground granulated garbage is larger, front The flexural deformation of plate 12 is larger, and demarcation strip 17 and suction tube 2 are promoted to higher position by height regulation drive device 3, demarcation strip 17 The distance between front end and front apron 2 become big so that the decrement of spring 19 diminishes, in free relaxation state, sealing plate 18 with The front end of demarcation strip 17 is located remotely from each other, and the front end of demarcation strip 17 remains to keep air-tightness to connect with front apron 12 by sealing plate 18 Touch.

It can be seen that, the cooperation based on sealing plate 18 Yu spring 14 lifts and transferred demarcation strip 17 in height regulation drive device 3 During suction tube 2, the front end of demarcation strip 17 keeps being in close contact all the time with front apron 12, realizes good sealing effectiveness. Certainly, spring 19 can also be other elastic components, as long as its support located at demarcation strip 17 front end and slot bottom wall between and Demarcation strip 17 can change the deflection of itself during moving up and down.

Moreover, the sealing plate 18 of the embodiment is also configured as elastic packing plate.So, driven in demarcation strip 17 on suction tube 2 During lower movement, not only spring 19 can produce its deformation along the longitudinal direction, and sealing plate 18 can also produce edge simultaneously The deformation of fore-and-aft direction, together with what the deformation of these two aspects can be between sealing plate 18 and demarcation strip 17 move forward and backward relatively, It is common to change the distance between sealing plate 18 and the front end of demarcation strip 17, make the front end of demarcation strip 17 all the time by sealing plate 18 with before Baffle plate 12 keeps being in close contact, and air-tightness effect is more preferable.Moreover, sealing plate 18 is set into elastic packing plate, its benefit also exists In, on the one hand, sealing plate 18 can better adapt to the lower end of front apron 12 into chamber 10 by changing the deformation of itself The characteristics of rolling oblique, realization is more closely contacted with front apron 12；On the other hand, flexibility connects between sealing plate 18 and front apron 12 Touch, the abrasion to front apron 12 can be not only reduced relative to the situation of rigid contact, sealing plate 18 is also prevented to front The deformation of plate 12 produces influence, so as to further improve accuracy of the detection means 4 to the deflection testing result of front apron 12, And then can further improve the adaptability of separation structure height and the height of suction tube 2 and different operating mode actual demands.

It can be seen that, in the embodiment, front end of the first contact adjustment structure not only with demarcation strip 17 can relatively movably forward and backward Connection, in addition to the elastic construction that can be deformed along the longitudinal direction, and elastic construction not only includes spring 34, in addition to sealing plate 18, under the collective effect for moving forward and backward and deforming along the longitudinal direction relatively, the first contact adjustment structure changes itself with separating Longitudinal separation between the front end of plate 17 so that the front end of demarcation strip 17 keeps being in close contact all the time with front apron 12, can more have Prevent gas from leaking to effect, the actual demand of different operating modes is adapted to for greater flexibility.And first contact adjustment structure elastic construction (spring 34 and sealing plate 18) does not influence the deformation of front apron 12, standard of the detection means 4 to the deflection testing result of front apron 12 True property is higher.

Second contact adjustment structure is arranged between the rear end of rear baffle 15 and demarcation strip 17, for by change itself with Distance between rear baffle 15 along the longitudinal direction realizes gas-tight contact between separation structure and rear baffle 15 to adjust.3rd Contact adjustment structure is arranged between the left end of left plate 13 and demarcation strip 17, for by changing itself between left plate 13 Distance in left-right direction realizes gas-tight contact between separation structure and left plate 13 to adjust.4th contact adjustment structure Between the right-hand member for being arranged at right plate 14 and demarcation strip 17, for by changing itself between the right plate 14 in left-right direction Distance realizes gas-tight contact between separation structure and right plate 14 to adjust.It is rear baffle 15, left due in this embodiment Side plate 13 and right plate 14 are non-resilient plate and equal general vertical is set, therefore, and the second contact adjustment structure, the 3rd structure are adjusted Nodule structure and the 4th contact adjustment structure are that demarcation strip 17 and rear baffle 15, left plate 13 can be achieved using relatively simple structure The better gas-tight contact between right plate 14.For example, the second contact adjustment structure of the embodiment, the regulation of the 3rd structure Structure and the 4th contact adjustment structure can use elastomer connector structure, and elastomer connector is respectively arranged in after demarcation strip 17 End, left end and right-hand member, make demarcation strip 17 be connect respectively with rear baffle 15, left plate 13 and right plate 14 by these elastomer connectors Touch, so during demarcation strip 17 drives suction tube 2 to move up and down, you can make demarcation strip 17 using the deformation of elastomer connector Keep being in close contact between rear baffle 15, left plate 13 and right plate 14, realize to inhale and pick up air-tightness of the chamber at these positions, Prevent that simple in construction, cost is relatively low because gas occurs leakage in these positions and influences to inhale the vacuum magnitude for picking up intracavitary.

In addition, as shown in Figure 2 and Figure 5, in this embodiment, demarcation strip 17 is waveform bending plate, and it includes several ripples Peak and several troughs, this causes the demarcation strip 17 of the embodiment to include the recess to lower recess and convex portion protruding upward.Due to The setting of recess, can reduce the height that chamber is picked up in suction when demarcation strip 17 is in identical height and position, therefore, by setting recess Help further to reduce the volume inhaled and pick up chamber.The volume that chamber is picked up due to inhaling is smaller, and it is slower that the intracavitary negative pressure rate of decay is picked up in suction, because This, by the way that demarcation strip 17 is set to recess, can further improve when demarcation strip 17 is moved to arbitrary height position The negative pressure distribution situation for picking up intracavitary is inhaled, increases suction, realizes more rapidly and process is picked up in more thoroughly rubbish suction.

More specifically, as shown in Figure 2, the demarcation strip 17 of the embodiment, it includes 4 crests (convex portion) and 3 troughs are (recessed Portion), this causes the demarcation strip 17 of the embodiment to include two M type units, so includes two W type units relative to demarcation strip 17 Situation, can more effectively reduce to inhale and pick up the volume of chamber.Certainly, the number of crest (convex portion) and trough (recess) is not limited to In this, as long as in fact, demarcation strip 17 includes even number crest (convex portion) and odd number trough (recess), and crest (convex portion) Number is more one than the number of trough (recess), it is possible to so that demarcation strip 17 repeats to extend by elementary cell of M types, rather than with W types are that elementary cell repeats to extend.

Moreover, as shown in Figure 2 and Figure 5, in this embodiment, two suction tubes 2 are respectively arranged at two troughs.Such two Individual suction tube 2 is arranged at recess, and is respectively positioned on the extreme lower position of corresponding recess.Based on this, on the one hand, can be in demarcation strip 17 When being moved to arbitrary height position, further the height of reduction suction tube 2, further reduces the volume inhaled and pick up chamber, increases to rubbish Suction；On the other hand, two sections of adjacent panels for forming recess facing the lower ending opening inclination of suction tube 2, can be to carrying rubbish Air play guiding function so that carry rubbish air can more smoothly and more efficiently enter suction tube 2 in.

Wherein, in order to further enhance the guiding function of the two sections of adjacent plate faces to form recess, in this embodiment, recess Extreme higher position and extreme lower position between difference in height could be arranged to be more than or equal to 40mm, in this case, formed it is recessed Angle between two sections of adjacent plate faces in portion is larger, can more effectively guide the air for carrying rubbish to enter in suction tube 2, enter one Efficiency is picked up in the suction that step improves to rubbish.

In the prior art, to pick up cavity volume larger for the suction between two neighboring suction tube 2, easily produces low regime and vortex, Cause refuse receptacle often occur to pick up phenomenon.So, in order to further solve the technical problem, as shown in Figure 2 and Figure 5, in the reality Apply in example, a trough is separated between being gone back between two troughs for setting two suction tubes 2, that is, in this embodiment, two Suction tube 2 is respectively arranged on two troughs (recess) of one trough (recess) of midfeather.Due to the ripple between two suction tubes 2 The height of chamber is picked up in the suction that paddy can be reduced between two suction tubes 2, therefore, and two adjacent suction tubes 2 are arranged at into midfeather one On two troughs (recess) of individual trough (recess), it can reduce and inhale the part being located between two neighboring suction tube 2 for picking up chamber Volume, so can effectively reduce because the suction between two neighboring suction tube 2 pick up cavity volume it is larger caused by low regime and vortex Area, can effectively reduce because low regime and vortex it is more caused by the risk picked up of refuse receptacle, enhancing suction nozzle of sweeping car is to rubbish Ability is picked up in the suction of rubbish.

In summary, the embodiment picks up cavity adjusting device by setting separation structure and inhaling, and by the way that suction tube 2 is set To be moving up and down so that suction nozzle of sweeping car can and in real time regulation automatic according to granulated garbage size inhale pick up the volume of chamber with And the height of suction tube 2, enable that the volume of chamber is picked up in suction and the height of suction tube 2 better adapts to actual condition demand, both can be with Enough suction is applied to smaller particle rubbish, can prevent again because the terrain clearance of suction tube 2 is too low and caused by larger particles rubbish The problem of rubbish can not be passed through, use is more convenient, flexible, and rubbish is inhaled and picks up more efficient, and it is more preferable that effect is picked up in rubbish suction；Separately Outside, the embodiment is by the way that suction tube 2 is arranged on the recess of demarcation strip 17 and to suction tube 2 on the demarcation strip 17 with recess Arrangement is optimized, and the negative pressure that intracavitary is picked up in suction can be made to be more evenly distributed, and is more effectively reduced low regime and vortex, is entered One step improves the suction of suction nozzle of sweeping car；Moreover, by setting contact adjustment structure on demarcation strip 17, can also be effectively improved The air-tightness for picking up chamber is inhaled, prevents gas from leaking.

It should be noted that, although above-described embodiment is only illustrated so that suction nozzle of sweeping car includes two suction tubes 2 as an example, but It will be appreciated by those skilled in the art that in other embodiments of the invention, the quantity of suction tube 2 can also for 1 or 2 with On.Wherein, when the quantity of suction tube 2 is at least two, the quantity phase that the recess quantity of demarcation strip 17 both can just with suction tube 2 Together, in this case, each suction tube 2 can correspondingly be set with each recess；Or, the recess quantity of demarcation strip 17 The quantity of suction tube 2 can be more than, each suction tube 2 can be still respectively arranged on a recess, and adjacent suction tube 2 can both be set On adjacent recess, it can also be arranged on two recesses of one recess of midfeather.It can be seen that, when suction nozzle of sweeping car includes During at least two suction tubes 2, demarcation strip 17 can at least have identical with this quantity of at least two suction tube 2 and one-to-one recessed Portion.In addition, when the quantity of suction tube 2 is at least two, can be by two suction tubes 2 of arbitrary neighborhood in this at least two suction tube 2 On two recesses for being respectively arranged at one recess of midfeather of demarcation strip 17, to pass through, the recess at interval reduces adjacent two The height of chamber is picked up in suction between individual suction tube 2, reduces the low regime and vortex in region between two neighboring suction tube 2.

The suction nozzle of sweeping car of the present invention is applied on sweeping machine, the sweeping efficiency of sweeping machine can be effectively lifted, and have Effect improves the cleaning effect of sweeping machine.So, present invention also offers a kind of sweeping machine, its sweeping machine for including the present invention is inhaled Mouth.

Moreover, using suction nozzle of sweeping car of the present invention sweeping machine, suction nozzle of sweeping car can also be fixed on sweeping machine compared with At high position, in the course of the work, directly inhaled by regulation and pick up the volume size of chamber to increase suction, without again by that will sweep Bus suction nozzle is wholy set at the lower position of sweeping machine, so as not to suction nozzle of sweeping car because oneself height is too low and with road surface or road The rubbish of larger particles is interfered on face, influences the normal work of sweeping machine and the normal suction of larger rubbish is picked up.

The exemplary embodiment of the present invention is the foregoing is only, is not intended to limit the invention, all spirit in the present invention Within principle, any modification, equivalent substitution and improvements made etc. should be included in the scope of the protection.
