Wherein the driving power on chassis adopts the mode of fluid motor-driven, and power ratio is larger.

Be in embodiment at some, adopt wheel undercarriage, wherein wheel undercarriage in certain embodiments, adopts trackless rubber-tyred chassis, and adopt steel wheel chassis in certain embodiments, wherein steel wheel is with steel tooth.

Another critical piece of slicer-loader except chassis is shovel mouth assembly, make, the assembly structure of shovel mouth assembly on chassis is similar to the structure such as loader, bulldozer a bit, nature, the active of loader and bulldozer is done in the front side of fore-and-aft direction, in the utility model embodiment then before and after fixing, side material loading.

Thus from fixed structure, as shown in FIG. 8 and 9, the afterbody of this shovel mouth assembly is assemblied in the front end on described chassis, by chassis is driven.

Shovel mouth assembly as shown in Figure 1, its foundation structure comprises:

Main shovel board 1, be off working state in FIG, the agent structure of main shovel board 1 is in level, be to be understood that, this kind equipment does not need usually in transit by self power, comprises and is transported to bottom tunnel, usually do not need himself power yet, thus, main shovel board 1 can be fixedly installed in certain embodiments.

Main shovel board 1 preferably has the configuration of pitching driving mechanism, to adapt to the operation under self-holding dynamic condition.

About the structure of main shovel board 1, as illustrated in fig. 1 and 2, the afterbody of this main shovel board 1 is for shoveling the connection of mouthful assembly and chassis, and in certain embodiments, main shovel board 1 can form the frame of shovel mouth assembly.And in further embodiments, main shovel board 1 is as the installing component in frame, frame or support body are arranged separately.

The front portion of main shovel board 1, namely in figure 1 the right-hand member of main shovel board 1, the bottom left section in Fig. 2, shovel has leader, thus the material of such as coal can be allowed to be up on shovel, and therefore leader is generally all configured to spear 15.

Should be appreciated that for loading the spear 15 of character generally speaking, is to have the structure being beneficial to material loading.Spear 15 inserts bottom material, by the rotation of rotating disk assembly, by the left of material switch to main shovel board 1 or on the conveyer on right side.

Main shovel board 1 is the parts of the first action producing material loading, mainly makes material upwards expect in main shovel board 1 from front and back, should be appreciated that due to spear 15 produces the uneven of thrust, material usually can to both sides trickling, but does not affect the general understanding that shovel expects.

In order to make trickling be in controlled state, as shown in Figure 2, the side of spear 15 is provided with a sideboard 20 in fig. 2, should be appreciated that and also can adopt fixed dam, drops down to this effluent to avoid material.

Sideboard 20 can be the arcuate structure shown in figure, also can adopt straight baffle arrangement, but easy buildup.

Action after shovel material is exactly material to main shovel board 1 side material toggling, thus realizes feeding to this side, and material toggling then needs a lower component to realize.

As shown in figures 1 and 3, provide in a rotating disk assembly 2, figure, the spindle mounted of this rotating disk assembly 2 in the middle part of main shovel board 1 above, when the state shown in Fig. 1, main shaft is vertically arranged, and so rotating disk card is then vertical with main shaft, produces level as shown in Figure 1.

In the structure shown in Fig. 3, rotating disk provide a kind of newly take off material mode, generally speaking, taking off material is usually all that the charge level of answering taking off material parts takes off material, and to take off material be all adopt to answer the charge level structure that Impact direction is vertical with such as plate as far as possible.

The present embodiment then have employed different takes off material mode, specifically as shown in Figure 3, in figure, main shaft is equipped with three pusher dogs, wherein pusher dog is vortex spiral arm or the arcuate structure of clockwise axle steer, what represent in Fig. 3 is a kind of arcuate structure, when so rotating, as Fig. 8 and 9, because material moves from front to back relative to low, thus there is certain extruding force backward, then pass through clockwise or rotate counterclockwise, realize taking off material to the side of main shovel board 1, wherein take off material to the right side in bobbin movement direction in Fig. 8, rotating disk rotates clockwise; And in fig .9, material is taken off in the left side to bobbin movement direction, rotating disk rotates counterclockwise.

About the pusher dog of arcuate structure, because its one end will be connected to main shaft side, therefore, its center of circle can not be dropped on main shaft, answers coal face can produce certain pressure angle at it, thus can produce must pusher effect.

Therefore, in further improving, can by the home position of adjustment arcuate structure, the pressure angle in coal face is met in adjustment, to adapt to different pusher abilities.

For turbulent structure, i.e. the whirlpool that produces of usual said such as eddy current, match the structure that spiral arm produces, as shown in Figure 3, turbulent structure is in order to adapt to the requirement of pressure angle, and the lift angle of vortex is not easily excessive.

Based on said structure, this material mode of taking off can effectively reduce and takes off material resistance, especially when running into the coal cinder of bulk, thus can ensure to take off carrying out smoothly of material.

Preferably, pusher dog forward extend spear 15, thus effectively can alleviate the amount of the coal on front side of spear 15, alleviate the resistance that slicer-loader moves ahead.

Especially, because the work plane little in other words at light section is mined, narrow space, requirement fuselage appearance is small-sized, cannot adopt high pulling torque motor, therefore, based on aforesaid structure, can load be effectively reduced, reduce tractive force required when slicer-loader work is advanced, thus relatively low power motor can be adapted to.

And then, be described main shaft configuration motor, drive described main shaft in order to export; About motor, if chassis is beneficial to configuration Hydraulic Station, then can adopt hydraulic motor, and the power density of hydraulic motor is larger, can the larger motor of installation power in relatively narrow and small installing space, thus adapt to the application of small section tunnel.

About described motor, also electro-motor can be adopted, i.e. motor, rotation motor 13 as shown in Figure 1.When adopting electro-motor, need to adopt explosion-proof electric motor.

Based on aforesaid structure, produce mode of coalingging as shown in Figure 8 and Figure 9, such as, shown in Fig. 8, above horizontal arrow represent the traffic direction of slicer-loader, conveyer belt 36 is carried backward, namely carries to the left from the right side figure.

When taking off material, direction of coalingging as shown in Figure 8 can be produced, coal is taken off on conveyer 36.

As can be seen from Figure 1, comparatively speaking, in the present embodiment, the vertical dimension of slicer-loader is relatively little, thus to possess on small section tunnel compliance better.

In addition, the material structure of taking off based on arc or turbulent structure takes off material, and greatly can reduce and take off material resistance, the loss of rotating disk self is also smaller.

When visiting before pusher dog, namely the overhanging end of pusher dog can extend on front side of spear 15, cleans out timely and piles up the coal of getting up, effectively can alleviate the running resistance of slicer-loader.

About the assembly structure of main shovel board 1 on front side of chassis, point out in aforesaid content, in some embodiments, main shovel board 1 can adopt the mode of fixing assembling, during fixing assembling, the use flexibility of slicer-loader is relatively poor, but also can meet the instructions for use under certain condition.

As shown in Figure 1, can see each hole up and down in figure on rear side of the main shovel board of left end 1, as shown in Figure 2, hole above corresponds to axis hole 19, and axis hole 19 has two, but on an axis, looks it is one in FIG simultaneously.

Hole above in Fig. 1, namely axis hole 19 is that main shovel board 1 exists the connecting shaft hole of chassis front end, Kong Ze below drives the connecting hole of the drive part of main shovel board 1 pitching (hole above drives main shovel board pitching, and hole is below the axis hole be connected with chassis front end).

Structure accordingly, described main shovel board 1 is articulated with described front end by horizontal hinge shaft, thus main shovel board 1 can be that axis does elevating movement with horizontal hinge shaft.

And then coupling said structure, correspondingly, described slicer-loader also comprises lifts shovel structure, and this is lifted shovel structure and is assemblied in described front end, and output connects described main shovel board 1, is axle pitching to drive main shovel board 1 with horizontal hinge shaft.

Thus, when main shovel board 1 is put down, namely in running order, can be used for pose adjustment when lifting or advance.

in Fig. 1, with the center of circle of circular hole above for axle, with hole below for connecting drive point, main shovel board 1 obtains a moment, can carry out pitching driving.

note, for two circular holes, hole above both can having been selected for connecting drive point, and the hole below also can having been selected for connecting drive point, can't therefore produce obvious difference.

Fig. 2 right part, each axis hole 19 is limited by two hinged otic placodes 18, so can arrange a connection otic placode be embedded between two hinged otic placodes 18 in the front end on chassis, lock after then wearing bearing pin, can ensure the reliability connected.

In the structure shown in Fig. 2, be also furnished with special backboard 17, fall from the rear side of main shovel board 1 in order to avoid coal.

In addition, for main shovel board 1 itself, designed by the gradient on such as inclined-plane, not arranging special backboard 17 is also to meet the effect not falling material on rear side of main shovel board 1.

Backboard 17 can also be configured to carry out the suitable effect led to charging, in other words, allows it flow to the side that such as sideboard 20 is relative.

Based on aforesaid structure, coupling backboard 17 can construct hopper construction, is conducive to material loading.

The structure of hopper construction can also construct based on the body shape of main shovel board 1, namely can pass through the shaping sheet metal component of integrated punching, can also adopt welding structural element.

In certain embodiments, main shovel board 1 is chosen as package assembly, the part being easy in the structure division of assembling lose efficacy can adopt releasable connection anatomical connectivity, can adopt welded construction, thus possess higher bonding strength for the structure division relatively grown application life.

For the leading parts of main shovel board 1, should avoid when moving ahead penetrating bottom tunnel, therefore, with this understanding, should have the structure of spear 15 being carried out to effectively guiding, in structure as shown in Figure 1, the bottom surface of spear 15 is planes, this plane and ground when the state shown in Fig. 1 and bottom surface, tunnel in an angle, be defined as inclined-plane relative to bottom surface, tunnel.

Based on this, the luffing angle of association slope and main shovel board 1, thus when lifting shovel structure and putting down, this inclined-plane just and bottom surface, tunnel fit, the operation of cooperation to spear 15 formed of fitting has guiding function, thus it can not be made to penetrate ground, and can ensure the even running forward of main shovel board 1.

In addition, as shown in Figure 1, when moving ahead, namely in figure, right-hand member is in front side, for lifting spade state in figure, apparently in figure show that the front lower skew back mask of spear 15 has another kind of guiding function, and main shovel board 1 can not be made directly to strike object below lower than spear tip.

About lifting shovel structure, mating the syndeton of main shovel board 1 at chassis front end, can drive based on the most basic four-bar mechanism of mechanical field, wherein chassis forms frame, and main shovel board 1, as a side link, relates to other two bars accordingly, namely another side link and a connecting rod, construct four-bar mechanism.

Wherein, another side link can adopt oscillating cylinder, and preferred swing hydraulic pressure cylinder.

Four-bar mechanism is still slightly aobvious complicated, thus in further selecting, described in lift shovel structure be that seat portion is assemblied in above horizontal hinge shafthydraulic cylinder, wherein the push rod of this hydraulic cylinder is engaged in main shovel board 1 upper back.

Wherein, the seat end of hydraulic cylinder should be hinged on chassis.

in addition, as shown in Figure 1, hole below, namely axis hole 19, sees Fig. 2, is furnished with a pair, for ensureing main shovel board position certainty in the lateral direction.

So about the link position of hydraulic cylinder, should be positioned in the lateral direction in the middle of two axis holes 19.

Another kind of configuration can also be had about lifting shovel structure, namely as shown in Figure 1 below hole be used for the connection on main shovel board 1 and chassis, axis hole is above for lifting the connection of shovel structure.

In other realize, one in Fig. 1 in upper and lower two holes, or an interstitial hole is set in the centre in two holes, these two Kong Ze no longer retain, on main shovel board, setting example is as suspension ring, adopt hang draw or front and back traction mode produce the driving that certain rotating torque realizes main shovel board.

About described pusher dog, preferred embodiment is found in the rotating disk assembly structure shown in the assembly structure shown in Fig. 3 and Fig. 5, and the foundation structure in figure is arcuate structure.

Shown in Figure of description 5, described pusher dog comprises:

Pawl body 28, for the flat board perpendicular to rotating shaft, or in the condition shown in figure 1, the structure parallel with bottom surface, tunnel, and this pawl body 28 has the jointing edge being positioned at described rotating shaft side, the centripetal end being benchmark with platen (in figure intermediate disc) namely shown in Fig. 5, this end is used for the assembling of pawl body 28.

Shown in Fig. 5 is plan structure, and under plan structure, pawl body 28 is blade bodies, and centripetal side is relatively large, and centrifugal side is relatively little.

Come to a point gradually from the centrifugal side of centripetal side direction in figure, thus also comprise based on pawl body described in direction of rotation and be positioned at front side answer limit and be positioned at rear side back of the body limit, wherein answer limit and the back of the body limit be convex curve limit.

Wherein, front side be with in Fig. 5 clockwise direction rotate time coal face of answering be front.

Should be appreciated that based on description above known, the present embodiment answers coal face to determine, namely with the front side that direction of rotation limits.Can comparative illustration book accompanying drawing 8 and 9.

And then, comprise further about pusher dog and answer panel 30, namely answer the plate body of side, coal face, be configured to the curved slab perpendicular to pawl body 28, correspondingly, described in answer the trailing flank of limit and this curved slab to coincide to be connected, generation structure as shown in Figure 5.

Generally speaking, the Ying Bianyu of pawl body 28 answers the lower edge of panel 30 to carry out the welding of end end.

In certain embodiments, answer the lower edge of panel 30 downward across pawl body 28 1 point, then can to weld, the part wherein exceeded is in order to certain gap reserved between pawl body 28 and the upper surface of main shovel board 1.

This gap is generally not more than 1cm, and is generally not less than 0.5cm.

Generally speaking, pusher dog adopts integral solder structure, and it changes the mode adopting integral replacing, and it uses as an accessory on the whole in other words, and need not carry out local replacing.

Repairing for parts against wear does not relate to the object of the integral replacing of leading portion indication, such as straightening, damage revamping.

For material toggling, especially raw coal is feeded, wherein comprise larger coal cinder, also the low-down petrifaction of some calorific values may be contained, possesses mutual hardness, larger impact can be produced to pusher dog, although the present embodiment adopts foregoing arcuate structure or turbulent structure, but still need to carry out structural strengthening to it.

A kind of mode of structural strengthening is that simple thickness thickens, and improve the shearing resistance section factor of himself, but the material cost of entirety is higher.

In some applications, answering the trailing flank profiling of panel 30 to be fitted with stiffener, stiffener is the one distortion simply thickened, and only stiffener is generally through analysis, carries out local strengthening and not all strengthen wherein needing the position strengthened.

Wherein, profiling refers to the curvature profiling corresponding to answering panel 30 trailing flank.

In certain embodiments, the horizontal end face of pusher dog is square frame, i.e. said rhs-structure, has very strong shear resistance.

When adopting stiffener structure, the width ratio that described stiffener is being parallel to rotating shaft axis answers panel 30 narrow, thus the reinforcement of corresponding panel 30 is more embodied in the reinforcement that corresponding panel 30 connects root, namely stiffener being engaged from answering panel 30 with pawl body 28 place, generally adopting welding.

If consider that welding the structural member produced becomes fragile, can heat-treat, or adopt riveted joint, riveted joint also has stronger bonding strength.

When adopting riveted joint, preferably adopt countersunk rivet.

A kind of structure is relatively simple but the structure that intensity still can ensure is provided with reinforcing rib 29 between the trailing flank and the plate face of pawl body 28 of stiffener, and as shown in Figure 5, in figure, reinforcing rib 29 is only provided with together, and arranges near the centripetal side of pawl body 28.

Reinforcing rib can arrange multiple tracks, and at least carries out local strengthening in the centripetal side of pawl body 28.

In the plan structure shown in Fig. 5, can find out that the width of pusher dog narrows to centrifugal side gradually from centripetal side, and narrow as protuberance at centrifugal end, be conducive to saving material, and own rotation inertia be relatively little.

Can also improve further said structure, be configured to, described pusher dog at the width of rotating shaft axis from pusher dog connection side to the centrifugal side rotated by wide to narrow.

Narrowing gradually about by wide, can be that step narrows, and is beneficial to processing.

About the connection between pusher dog and main shaft, because pusher dog is main charging parts, the impact be subject to is relatively large, and therefore, pusher dog easily lost efficacy.For this reason, the connection of pusher dog and main shaft should adopt releasable connection as far as possible.

For the connection of pusher dog and main shaft, can adopt and arrange the diskware that a layout has axial hole on main shaft, pusher dog is arranged on this diskware by bolt.

In certain embodiments, as shown in Figure 1, in figure, be furnished with a platen 9, coordinate this platen 9 to be arranged on main shaft by pusher dog by soket head cap screw 3.

In view of field working conditions is severe, such as coal dust easily enters main shaft bearing, and produce abrasive wear or rigidity damage, for this reason, described pusher dog is installed on main shaft by shaft seal operator guards, avoids such as coal dust to enter the braced structures of main shaft as much as possible.

In the construction shown in fig. 1, described shaft seal operator guards comprises the platen 9 of a coverage rate towards main shaft upper end, and form the end cap of axle head, end cap effectively can protect axle head, forms shaft end seal.

End cap can be configured to the bearing cover of main shaft in certain embodiments.

Pusher dog is assemblied on platen 9, instead of is directly connected with main shaft, reduce the interference to main shaft sealing construction.
