Description
The present invention relates to a kind of side-dumping loader that is used in underground work, this side-dumping loader is by full tracked chassis, and vehicle frame shovels arm, and scraper bowl fork and side dump scraper bowl are formed.The shovel arm can be installed on the vehicle frame rotationally, can lifting, can also swing around a vertical axis.The scraper bowl fork is contained in the free end of shovel arm, can be by the lifting of scraper bowl cylinder.The side dump scraper bowl is connected with the scraper bowl fork, and can be selectively to scraper bowl both sides skew back.
Such known side-dumping loader has two kinds, and a kind of is to have the lever system loader of non-telescoping lifting arm as the shovel arm, and another kind is the telescopic loading trough machine with telescopic shovel arm.Fixing interior dress teeth is all arranged on the lower scraping plate of the side dump scraper bowl of these two kinds of loaders.These two kinds of known side-dumping loaders are through facts have proved the loading operation that is applicable to underground.But, will produce difficulty if need the mineral of loading to contain lump ore.
From the patent DE-AI-2813202 of Germany, can know, use percussion tool to provide impact power to the part of power shovel lower scraping plate.
The objective of the invention is to improve the delivered payload capability that side-dumping loader loads lump ore.
The method that realizes above-mentioned improvement according to the present invention is that in above-mentioned first kind of side-dumping loader, at least a portion of side dump scraper bowl lower scraping plate provides impact power by at least one percussion tool of affiliated percussion mechanism.Preferably adopt hydraulically powered percussion mechanism.What load if desired is the relatively large ore that explosion produces, use loader of the present invention so after, lump ore just can be by at least one above-mentioned percussion tool fragmentation before scooping up.Like this, on the one hand convenient loading operation, the transportation of also convenient on the other hand mineral and processing operation thereafter.Another advantage is, can more successfully shovel in the thick ore that explosion produces according to the invention provides the side dump scraper bowl that impacts power, so just helps gathering in scooping up operation mineral.The scraper bowl of this drive is applicable to that also ground is smooth.The edge, irregular ground that inhomogeneous explosion produces can be evened out by the lower scraping plate of the drive of side dump scraper bowl.
The one group of percussion tool and the affiliated percussion mechanism that are arranged side by side along the scraper bowl lower scraping plate make side dump scraper bowl bottom have special compact structure.
Percussion mechanism can be arranged under the scraper bowl plate of side dump scraper bowl, and this layout scoops up mineral with can guaranteeing basic fault-free.
Percussion mechanism can be arranged in the percussion mechanism case that is fixed in below the side dump scraper bowl, and this layout makes structure very firm.The assembling percussion mechanism is very easy in the percussion mechanism case.
In the another kind of loader of the present invention is arranged, scraper bowl is not during skew back, and percussion tool towards upper and lower to the time, the scraper bowl bottom surface can be driven by the scraper bowl cylinder and adjust the position in the angular range with respect to 0 ° to 90 ° on ground.These characteristics help broken bulk mineral.When the bottom surface of this side dump scraper bowl was adjusted suddenly, this crushing action can prevent the nonconforming transverse movement of the bulk mineral that will be broken effectively.But in general, particularly the ore of bulk is to fix the locational of it by mineral on every side in the process that is broken.
Percussion tool or each percussion tool can stretch out one forward than lower scraping plate and give fixed amount.So just can guarantee that one of all percussion tools at first touch the mineral of wanting broken, and have only the mineral after fragmentation just can contact with lower scraping plate.
Other characteristics of the present invention and advantage will contrast the following drawings and further specify in to the specific embodiment of the invention.

Fig. 4 is the elevation along the IV-IV line of Fig. 5, is depicted as half of a kind of embodiment of side dump scraper bowl:
Fig. 5 is the sectional view along Fig. 4 V-V line.
Shown in Figure 1 is side-dumping loader 1, and its underpart is golden crawler body 2.Shovel arm 4 is contained on the vehicle frame 3, can make pivotal movement.Shovel arm 4 can be around a horizontal axis 5 pivoting liftings by promoting that cylinder 6 and 7 (also can consult Fig. 2 and 3) drives, and also can make pivotal movement around a vertical axis 8 by turning to cylinder 9 to drive.
Free end at inner core 12 is equipped with a scraper bowl fork 13, and scraper bowl fork 13 can swing up and down around a horizontal axis 15 by scraper bowl cylinder 14.
One side dump scraper bowl 16 is contained on the scraper bowl fork 13 so that selectively around one of two skew back axis 17 and 18 skew back.In Fig. 1 to 3 illustrated embodiment, skew back axis 17 is to pass the lug 20 of scraper bowl fork 13 and 21 bolt limits by one.
Skew back motion realizes by skew back cylinder 22, tilt cylinders 22 on the one hand with the scraper bowl fork on center tie point 23 forever be connected, on the other hand with the side dump scraper bowl on outer tie point 24 or 25 optionally be connected.As shown in Figure 2, occur between tie point 23 and 24 if connect, so, as shown in Figure 3, the side dump scraper bowl will be around bolt 19 (being skew back axis 17) skew back.If wish side dump scraper bowl 16 skew back in the opposite direction,, and it is inserted along skew back axis 18 as long as withdraw from bolt 19 so.In addition, need unclamp skew back cylinder 22 tie point 24 outside it and it is connected to outside another on tie point 25.
Side dump scraper bowl 16 has the shaped form scraper bowl plate 26 that holds mineral.Scraper bowl plate 26 ends at the scraper bowl bottom front, and join with lower scraping plate 27 (seeing Fig. 2 and Fig. 3), the part of lower scraping plate 27 provides impact power by six percussion tools 28 with affiliated percussion mechanism 29.Another embodiment describes the structure of percussion mechanism 29 in detail and situation is set shown in the contrast Figure 4 and 5 below, Fig. 1 and embodiment illustrated in fig. 3 in also use same layout.Percussion mechanism 29 is arranged in parallel, is contained in the percussion mechanism case 30 of side dump scraper bowl 16 downsides to be protected, and loading and unloading easily.Percussion mechanism 29 is preferably hydraulic operated, and provides hydraulic oil by the hydraulic pressure system on the side-dumping loader.If do not adopt six percussion tools 28 shown in Figure 2 and affiliated percussion mechanism 29, can install more or less percussion tool and percussion mechanism thereof yet.
Side-dumping loader 1 initial design is used for scooping up underground mineral, and utilizing side dump scraper bowl 16 that mineral are sent to chain transfer ends, perhaps also mineral are conveyed into mine car occasionally, this transmission all is to finish with the skew back of side dump scraper bowl 16.Can be at the both sides of side dump scraper bowl 16 main bodys bolt gatherer, this can make this transmission very convenient.
When carrying out above-mentioned common loading operation, at first side dump scraper bowl 16 is placed the original position shown in Fig. 1 solid line.The side dump scraper bowl is inserted in forward under the mineral or among the mineral, and this can finish by the forward travel of side-dumping loader 1 or by the stretching, extension of shovel arm 4.Therefore in general, scraper bowl cylinder 14 starts at the same time, and along with the advancing of side dump scraper bowl 16, its receiving opening scoops up mineral so gradually towards the top.Because side dump scraper bowl 16 displacement forward, the bottom surface 33 of side dump scraper bowl 16 are basically parallel to ground 34 motions.Adopt this side-dumping loader 1, ground 34 can be dug low certain distance downwards.For this purpose, side dump scraper bowl 16 can be realized the other several operating positions shown in Fig. 1 dotted line.Operating position therein, scraper bowl bottom surface 33 and ground shape at an angle 35.As required, angle 35 even can be bigger can reach 90 ° under limiting case.Like this, it is steep especially that bottom surface 33 will become, thereby can use percussion tool 28 broken bulk mineral before loading and unloading mineral in the above described manner.This just means that side-dumping loader has increased its operant activity greatly and reduced the working time, is necessary originally because can save, the special comminution process of finishing with other equipment.
Provide another important advantage of impact force to be to lower scraping plate 27, the side dump scraper bowl 16 with percussion tool 28 can more easily insert mineral in scooping up process, particularly inserts in the thick ore after the explosion.And the consequence of the disadvantageous explosion that the uneven incorrect often shot hole of ore size produces.
Adopt the side dump scraper bowl 16 that has power of the present invention, not only can face down ground and dig low certain distance, and ground grading as required.When producing uneven edge, just need this smooth operation because of inhomogeneous explosion.This uneven edge can be removed and leveling with the side dump scraper bowl of this power.
In all these embodiments, the freedom of motion of shovel arm 4 and side dump scraper bowl 16 all obtains combination and utilization in best mode.Fig. 2 shows the full swing scope of shovel arm 4 around vertical axis 8, and shovel arm 4 can be swung between with respect to the angle 36 and 37 of longitudinal centre line both sides.
Side-dumping loader does not adopt flexible shovel arm 4, can adopt non-flexible push and pull system in known manner yet.
In the embodiment shown in the Figure 4 and 5, the part identical with Fig. 1 to 3 illustrated embodiment uses identical label.
In Figure 4 and 5, lower scraping plate 27 adopts 5 percussion tools 28 and percussion mechanism 29 thereof that impact power is provided.
Each percussion mechanism 29 (Fig. 5) all uses bolt 40 to be fixed on the percussion mechanism case 30, and these bolts pass the front flange 38 of fixed cover 39 (Fig. 5).
As shown in Figure 5, each percussion mechanism 39 promptly to illustrated right-hand, inserts in the opening of a mounting blocks 41 of percussion mechanism case 30 all backward.Have connecting hole on the mounting blocks 41, connecting hole is communicated with pressure piping 42 on the one hand, is communicated with the return line 43 of percussion mechanism case 30 on the other hand.
Shown in Fig. 5 left side, each percussion mechanism 29 is bearing on the fixed cover 39 by leaf spring 44.The working piston 45 of each percussion mechanism and 46 interoperation of affiliated percussion tool 28.Every axle 46 can vertically move in a pilot sleeve 47, and also has another device (not shown) guiding that it can not be rotated around the longitudinal axis.Pilot sleeve 47 is arranged in the fixed cover 39.
As can be seen from Figure 5, percussion tool 28 no matter in its last position, still in its most preceding position, all exceeds lower scraping plate 27 1 segment distances 48 of side dump scraper bowl 16 at least forward.This has just guaranteed when percussion mechanism 29 starts, the ore that contact at first will be broken be percussion tool 28.Have only being broken of preparing to scoop up mineral just contact with lower scraping plate 27, then mineral again through lower scraping plate to scraper bowl plate 26.
