Suction in the present embodiment and gathering-device 5 comprise the device that is used to produce a low pressure 30, such as a turbine, a shell 31 will dig partly that furrow wheel 4 is closed and with turbine 30 be used to collect the collection bucket or the collection container 32 that suck spoir and be connected.This turbine and collection bucket are to be installed in above the chassis 2 of motorized vehicles 1 as can be seen from attached Fig. 1 and 2.
Particularly, this shell 31 be connected on the framework 17 of pick furrow wheel and its sealed the Outboard Sections 4A of pick furrow wheel 4 in the irrigation canals and ditches outside, inside part 4B is the inboard at irrigation canals and ditches simultaneously.From configuration aspects, these shell 31 side semicirculars in shape, the structure of sectional view is inverted U-shaped, and its inside is installed with the pick furrow wheel of appropriate section.This shell end at by outer rim 33 form widen the bottom or base plate, this outer rim contacts with ground S shown in accompanying drawing 1,3 and 4.Like this, a better relatively sealed space 34 is able to form between the corresponding 4A part that is closed with the pick furrow wheel of shell 31.In addition, institute's housing mounted 31 can be parallel to its side slip on the framework of pick furrow wheel, so that according to the degree of depth of institute's ditching canal, according to the arrow F direction that this pick furrow wheel 4B with respect to shell partly locates, adjusts it highly.This Height Adjustment amount of shell be by with shell and framework lateral junction altogether slideway 35 and the not shown drive unit that shell is slided with respect to the framework outside obtain.
In the present embodiment, turbine 30 is connected with the fingerprint 32 that is used to collect spoir, and is connected with inner space 34 between shell and the wheel by a flexible delivery.The latter is between pick furrow wheel and vehicle chassis rear portion, it is connected to suction gland 37 places in the shell on the one hand, the chances are is connected to felly when leaving irrigation canals and ditches cutting face FT from the direction of tangent line, then be connected to inner air circulation canal 38 places of equipment 5 again, cross fingerprint 32, and be connected on the turbine 30 by a series of strainer (not shown), open at 39 places, top of vehicle 1.
This fingerprint 32 preferably is hingedly mounted on the vehicle chassis, and is so that can tilt to one side by actuator cylinder, not shown.
In addition, such as be connected shell suction gland 37 places be an end of additional flexibility pipe 40, and its other end enters into the rear portion of the shell 31 that is covered with pick furrow wheel 4, so that suck at the remaining spoir in irrigation canals and ditches T bottom, shown in the arrow in the accompanying drawing 3 along outer ledge BT.
We describe the situation of this motorized vehicles 1 and its relevant device 3 and 5 work now.
The vehicle 1 that at first must point out to have the channel(l)ing wheel of excavating equipment is no more than 15 meters long when its operating position, it has reduced the length of employed mechanized part up to now to a great extent, and has more increased its mobility and yarage in mining process.
The direction of rotation of the travel direction of this vehicle 1 and wheel 4 is represented with arrow A and R respectively.
In excavating the irrigation canals and ditches process, vehicle 1 drives by a hydraulic power transmission system, and this system also drives different optional equipment (actuator cylinder, motor etc.) simultaneously, and makes tunneling process be easier to adapt to the mining process of irrigation canals and ditches.
Suppose that herein irrigation canals and ditches T by what dug along the pick furrow wheel 4 in the excavating equipment 3 of vehicle center length direction X-X axle installation, meets at right angles with vehicle chassis 2 planes.Certainly, this pick furrow wheel 4 can occupy any other lateral attitude by its columns 8 that slide along slideway 9, and this slideway 9 links with the rear portion of vehicle chassis, simultaneously according to working condition itself in addition can occupy the peak excursion position that is used to excavate irrigation canals and ditches.
By with respect to pick furrow wheel mobile shell 31 and can adjust the degree of depth of institute's ditching canal with respect to column 8 traversing carriages 12, simultaneously around its pin 26 pivot frame of hinged frame 17, this pick furrow wheel 4 by gear motor parts 18 rotation that drives promptly is dug into ground S, wheel rim 33 until shell touches ground surface, make like this between the part 4A of shell 31 and corresponding pick furrow wheel, to form a relative sealed space 34, in the irrigation canals and ditches outside.Such shell has formed effective protection again for the operator.Because this vehicle 1 is moved by its hydraulic power transmission system and this pick furrow wheel rotation, this cutting element 14 is excavated irrigation canals and ditches T (shown in the accompanying drawing 1-4) gradually.
Irrigation canals and ditches are delivered in the shell along the spoir D that cutting face FT is produced, and by the operation of suction and collecting device 5, inner space 34 becomes vacuum, and become " sealing " contact between shell and the ground.The amplification details that goes out as shown in Figure 3, spoir D is inhaled into towards phase flexible delivery 36 after leaving cutting face FT, because is that tangent line is provided with and digs element 14 simultaneously spoir is ejected at the suction pipe that leaves cutting face place shell with respect to the pick furrow wheel, institute is so that suction process is optimized.
Like this, the vacuum that is produced by turbine 30 can be weakened has accordingly had a high inhalation rate simultaneously, and this makes and uses the box-shaped collection bucket that has than the bigger volume of hydrostatic column that condition of high vacuum degree is arranged to become possibility.
In fingerprint 32, most suction spoir D is collected, and in the remaining filtration system that is collected equipment 5 on a small quantity, so what discharge has been exactly clean air from exporting 39.
In addition, this additional flexible delivery 40 has been improved the suction process of spoir again, particularly with the rotation of pick furrow wheel some away from spoir can retreat into bottom the BT place, outer survey edge of irrigation canals and ditches T or its in.
All like this spoirs just all are collected into fingerprint 32 by carrier pipe 36 and 40 or strainer has suffered.Be pointed out that they are (the shells of sealing that are collected in " sealing " loop, flexible delivery, collection bucket, strainer), it means that all operations is cleaning and irrelevant with operator and relevant environment, and this is very favorable for excavating irrigation canals and ditches on the road network in the city.
After irrigation canals and ditches T dug, the pick furrow wheel of excavating gear 3 can be raised up on the vehicle chassis 2 easily, did not travel on highway network so that this vehicle 1 can have difficulty and conforms with regularly.
Specified operational procedure is as follows.
The actuator cylinder 27 of framework 17 is set to retracted position, makes hinged frame pivot around pin 26.The pick furrow wheel 4 that has an interconnected shell 31 tilts to the lift location shown in chain-dotted line the accompanying drawing 3 from its lower operating position.The corresponding actuator cylinder 13 of 12 quilts of support that is carrying the device 3 of wheel framework moves to the lift location with respect to column 8, and column is then by being moved by transverse slipway 9 slips of actuator cylinder 10 along vehicle chassis 2, till contacting the end points of advancing.Operate the actuator cylinder 23 of deformable parallelogram bindiny mechanism 19, make the framework 17 of pick furrow wheel obtain maximum biasing with respect to vehicle, position shown in the chain-dotted line in the accompanying drawing 2, in this position, pivot pin is positioned at outside the width of vehicle.The rotating power cylinder 25 of this pivot pin 24 also is activated, and makes framework 17 carry 4 rotations (accompanying drawing 5) of pick furrow wheel.
As accompanying drawing 5, embodiment described in 6 and 7, after column 8 was slided along slideway 9 by actuator cylinder 10, framework 17 and dig furrow wheel 4 accordingly around pivotal axis Rotate 180 degree made the side plane of pick furrow wheel place for vertical X-X axle (meeting at right angles with the vehicle chassis plane) direction along vehicle.Like this, this excavating gear 3 just has been placed in the vehicle chassis, does not have ledge, and the pick furrow wheel also has been positioned at its transporting position.
Yet, shown in accompanying drawing 7A and 7B difference, deformable parallelogram bindiny mechanism 19 being switched to opposite side by actuator cylinder 23, the rotation of this framework also can be different, for example is about 150 degree, or or even 130 degree.4 of this pick furrow wheels are mounted with an angle of inclination with respect to vehicle chassis X-X axle, and occupy less space at the vehicle chassis rear portion, and this makes collection bucket can have bigger spatial volume.
