Description

Collect the sweeping machine that rubbish is used

The present invention relates to a kind of sweeping machine that rubbish is used of collecting.

Known type be used to clean sweeping machine such as wide area surface such as road surfaces, usually has a driver's cabin, one is used to store water so that water is sprinkled upon the storage tank to prevent to stir up a cloud of dust on the ground before removing rubbish, a dustbin that stores the rubbish that picks up from ground, and a plurality of brush that directly contacts with ground.

Aforesaid various sweeping machine, every day should the continuous operation several hrs, needs the water tank of dustbin and big volume especially so that enough strokes are provided, avoiding frequent stop to unload puts rubbish and fills out water again.Same appropriate is that driver's cabin should be arranged, overtired to avoid the driver.

Each sweeping machine also is equipped with brush usually, comprises the side brush of cup-shaped and is located substantially on the cylindrical brush or the round brush at sweeping machine middle part, becomes the critical element when working on the ground.

Cup-shaped brush itself comprises at least two height-adjustable sides brushes again, and basically within the profile scope of car, its effect is under the waste material that will be eliminated or the rubbish Guide vehicle and the main center of guiding round brush.

The center round brush also will be adjusted height usually, and its effect is cleaning ground, and will comprise that those push dustbin inside to from all rubbish that side brush comes.

Under total situation, auxiliary round brush is equipped with in dustbin inside, it separates with main rolling brush by belt drive unit, and its configuration helps rubbish is shifted in the dustbin by the thrust that helps main rolling brush, prevents under the situation of a large amount of rubbish that rubbish from shifting out containing especially.

On above-mentioned brush, particularly on the round brush of main center, the watering spout is housed, link to each other with pump with above-mentioned storage tank.The water that spills earthward stops the dust of kicking up by cup-shaped brush and round brush.

One row's sprinkler head is housed on the privileged site of main center round brush especially, strong spray function is provided, because the center round brush promotes rubbish and pushes in the dustbin, it generally all raises a huge cloud of dust.The dust that is sent to round brush zone, main center is also pushed in the dustbin from inlet.

Some sweeping machine also includes an additional pilot bruss except that two side brushes, laterally place in vehicle frame the place ahead, picks up rubbish from road both sides or sidewalk.Should additional brush with the rubbish both sides brush that leads, additional brush moves to outside the sweeping machine gabarit, is easy to reach with two sides that are equipped on the sweeping machine brush the place that is difficult to clean.

First shortcoming of above-mentioned sweeping machine is too huge, this be because require that large-sized dustbin is arranged, due to the big capacity storage tank, comfortable driver's cabin and rubbish guiding device.Bulky being harmful to is because its hinders action rapidly with the place that reaches all cleanings with cross any obstruction.This huge sweeping machine also brings problem to normal road traffic.

Another shortcoming of the sweeping machine of known type is, even main center round brush assists it that rubbish is pushed in the dustbin by proper device, it trends towards the nearby part of sanitary fill in case.Therefore, dustbin is not deposited at the bottom of the dustbin equably, can not fully use its capacity, and pushes away long-pending rubbish and can hinder entering of more rubbish.

Although should also be noted that watering device, to execute and change brush and round brush a large amount of dust of kicking up, these dust are diffused in the air, can not be imported into dustbin, deposit again later on and get back on the ground.In addition, in the time of cold local of weather or in the winter time, weaken the usefulness water generates so-called " gloss effect " (Varnish effect) of airborne dust, promptly form ice sheet.

Also having a shortcoming is that above-mentioned additional brush only suits to make operator's manipulation like this in a side job of sweeping machine, and it is very inconvenient and difficult for example will to pick up rubbish on the opposite side with respect to the sweeping machine direction of travel.

Consider above situation, technical approach of the present invention provides the sweeping machine that a kind of collection rubbish that can eliminate above-mentioned shortcoming is basically used.

Conveyer 7 near dustbin 5 is flat basically on the length direction of sweeping machine, almost crosses the width of vehicle frame 2.In short transverse, conveyer 7 stretches between the top height of the opening 16 on the bottom of brush 8 height and the dividing plate 15 perpendicular to surface 9.

As shown in Figure 2, conveyer 7 has open structure, and suction air flow is therefrom flow through.Conveyer 7 is made up of two support guide chains 26, and they are separated from each other and are extended into a ring.Sprocket wheel 27 be driven and with chain 26 engagement, chain drive-belt and it is turned to.A plurality of conveying paddles 28 are connected on the chain 26 with separating each other.

Chain stretching device (not shown) with special configuration keeps tensioning with chain 26, prevents any swing of paddle 28.

Chain 26 and sprocket wheel 27 should be configured like this, so that paddle 28 forms a upward stroke and descending stroke, they are parallel to each other and separately, form the stroke that picks up rubbish of a bottom and the throwing stroke on a top, in the throwing stroke rubbish are thrown into dustbin 5 by opening 16.

Transfer passage 29 surrounds conveyer 7, equally also is vertical.29 pairs of suction air flow that flow through conveyer 7 of transfer passage play guider.

A wallboard of transfer passage 29 is made up of dividing plate 15, away from dividing plate 15 places a shaping wallboard 30 is arranged, the both ends bending that it is flexible, local linking transfer passage 29.In fact bottom 30a and upper end 30b can be divided in both ends, and upper end 30b can outwards change, and case 5 can be promoted; And bottom 30a can outwards change, and rubbish can be passed through, and its two sides contacts with rubbish, as shown in Figure 1.

In fact, its non-one side towards ground forms guider or the chute of rubbish materials flow to conveyer.

Act on the brush 8 of surface on 9, be positioned at front portion and middle part below the vehicle frame 2.

31, one its shaft parallels of side brush that brush comprises two cup-shapeds brush 33 before the main center round brush 32 on surface 9 and one also are cup-shaped additional auxiliary.

Both sides brush 31 reverse rotations each other are with rubbish guiding centre round brush 32.When sweeping machine 1 moved forward, center round brush 32 was to be in reverse to wheel 4A, and the direction of 4b is rotated, and is positioned at the rear of the bottom of conveyer 7, and garbage waste is thrown to conveyer.Should note, the circumference of the bottom of encirclement center round brush 32 and conveyer 7, vertical both sides along sweeping machine 1 have longitudinal baffle 34(to see Fig. 6 and 7), have diaphragm 35(to see Fig. 1 at the rear of center round brush 32), have the bottom 30a(of shaping wallboard 30 to see Fig. 1 and 2 in conveyer 7 the place aheads).As seen the bottom of main rolling brush 32 and conveyer 7 is to insert in a shell 36 by the substantial transverse sealing of flexible diaphragm.

Pilot bruss 33 can cross the anterior 2a of sweeping machine 1 according to operator's manipulation requirement, separate and different working region between be shifted, shown in Fig. 3,4 and 5.This moving is to be controlled by the transmission device 37 shown in Fig. 8 and 9, and transmission device 37 is directly handled the arm 38 that pilot bruss 33 is housed in rotary manner.

Transmission device 37 comprises slide 39, balladeur train 40 and tumbler 41.

Slide 39 is connected with the entire front end of vehicle frame 2 and the extending transversely (see figure 5), and slide 39 is made up of tube element.

Balladeur train 40 inserts in slide 39, and by cleaning surperficial male ≈ 2 support arms 38 perpendicular to quilt, the tumbler 41 to little axle 42 effects is laid in balladeur train 40 inside.Balladeur train 40 is by piston apparatus 43 transmissions that are placed in slide 39 outsides.

Transmission device 41 comprises changes cylinder 44, by connecting rod 44a act on one group with 42 gear that are fastenedly connected 45 on.Arm 38 is fastening with axle 42.

Fig. 9 demonstrates in detail, arm 38 have one be placed on axle 42 axially on actuating section 46, adjustable arm makes pilot bruss 33 under static state can reach and remain on one near (Fig. 4) on the position of sweeping machine gabarit; Also has a coupling part that constitutes by quadrilateral connecting rod 47.Connecting rod 47 can turn round in a vertical plane parallel with little axle 42.Connecting rod comprises underarm 48, upper arm 49 and is used for the whole piston-cylinder apparatus 50 that changes the position of upper arm 49 and quadrilateral connecting rod.Regulating part 51 also is housed, is used to regulate the length of underarm 48, so that only change the gradient of pilot bruss 33.

Be directly installed on the motor 52 on the pilot bruss 33, roll brush 33 in the running.

Storage tank 10 has less size, is flat basically on the sweeping machine length direction, and places near driver's cabin 3, so that with driver's cabin and conveyer 7 sound insulation and heat insulation.Storage tank constitutes a part of sending water system.Send water system also to comprise known water pump, waterway 53 and a plurality of spout 54.Spout can advantageously only be installed on cup-shaped

brush

31 and 33, weakening flying upward of dust, and except round brush 32 places, because there has been suction air flow at this place in action.Show among the figure that spout 54 is along disposing around the aquaporin 53 that stretches on above-mentioned brush.

The operating process of sweeping machine is as described below.

As shown in Fig. 3,4,5, the operator can be placed on pilot bruss 33 on the position that needs, thereby can finish large-area all work that need clean at once when the driving sweeping machine advance.Specifically, the operator can realize pilot bruss 33 correct height on the ground by application piston cylinder assembly 50, and piston-cylinder apparatus 50 can change upper arm 49 and underarm by the position in 47 restricted portions of quadrilateral connecting rod.

If

arm

48 and 49 has different length, the inclination of pilot bruss 33 changes brush height on the ground, but in all cases, the operator also can regulate regulating part 51, so that adjust the correct gradient of pilot bruss 33 with respect to ground, in order to rubbish material guiding side is brushed 31, round brush 32 again leads after the flexible bottom 30a by shaping wallboard 30.

Turning to of round brush 32 with to take turns the direction of advancing opposite, so it throws forward back the rubbish that receives, and forces it to move past above-mentioned bottom part 30a, arrives in the active region of conveyer 7 bottoms and paddle 28 thereof.

Paddle 28 is through the passage that picks up away from round brush 32, then by with shaping wallboard 30 near but discontiguous upward stroke.Vertical moving can be brought into the rubbish material by paddle 28, also requires not lean on shaping wallboard 30, the possibility of reducing friction arranged thereupon and obtain fast moving.

Upward stroke takes rubbish on the higher position with respect to the platform of dustbin 5 to, thereby effective charging ability of great use is provided.Even when dustbin 5 approaching being full of, still might carry out charging work.

Then, paddle 28 is passed by one section rubbish is thrown into the distance of dustbin 5 by opening 16, as shown in Figure 1, retracts towards round brush 32 then, finishes the descending stroke of its passage.

Charging work is strengthened greatly by strong suction air flow, and suction air flow is also with in dust and other particulate guiding dustbin 5.Air stream is produced by turbine 20, and turbine 20 passes through filter set 19 from dustbin 5 inboard suction airs.Filter set prevents that dust from being dished out outside the sweeping machine.

Although conveyer 7 is arranged, air stream also acts on by on the position on cleaning surface 9, and this is based on the conveyer 7 that has open architecture simultaneously, around due to the shell 36 of the transfer passage 29 of conveyer outside and sealing round brush 32 and conveyer bottom.In fact, formed the pumping components of an abundance, stretched to surface 9 from dustbin 5, and surround conveyer 7 and round brush 32 uniquely.

Dustbin 5 is not blocked in the existence of turbine 20, does not hinder the rolling motion of case yet, and this is that this suction pipe can be divided into two parts that can take apart mutually owing to have suction pipe.

The strong suction effect that is provided makes surface 9 waterings is become not needing very to capture this operation of dust.Therefore can give meter is placed on 54 of spouts above the cup-shaped brush 31 and 33.Like this, significantly eliminated the shortcoming of road pavement watering on the one hand, had on the other hand and storage tank 10 can be made less volume, thereby make sweeping machine more compact.The position of storage tank can also be to 3 buffer actions of driver's cabin.

Reducing also because due to the vertical flat pattern of water tank 10 and conveyer 7 of size, and because charging realizes that from the top high conveyer 7 allows to adopt due to the dustbin of higher structure.

The structure of conveyer, storage tank, brush and turbine is favourable, also because these members keep clear of wheel, do not exceed outside the sweeping machine profile (except pilot bruss 33 for except the intentional arrangement person), and the not lifting of interference dustbin 5.

When dustbin 5 is equipped with the pipe used in cleaning pit and gutter with the suction pump relevant with above-mentioned pipe, the existing suction air flow that is produced by turbine 20 also makes these operate more effectively and be easy to finish, and this is because the swabbing action of turbine strengthens the effect for the pump of above-mentioned pipe use.
