description and claims.
The shoveling machine of the present invention comprises a mobile base, a scoop-supporting and guiding structure pivotally attached to said mobile base, power means for swinging said scoop-supporting and guiding structure about the pivotal connection between the latter and said mobile base, a scoop (or bucket), a scoop- Another object of the invention is the Other objects of the invention will be apparent from a consideration of the following material from said hopper and to terial to a car or truck.
The mobile base may be provided with any suitable tractor-mount depending on the particular requirements and for purposes of illustration is shown as including a track wheel-mounted chassis. The scoop supporting structuremay be a table or deck, mounted on said mobilebase and with a pivotal connection between it and the move the malatter, on which table or deck the scoop-rocking mechanism moves, e. g., in a predetermined fixed path. The hopper is so positioned as to receive material from said scoop regardless of the hori zontally lateral position of the scoop-supporting and guiding structure; that is to say, is positioned at the point of discharge common to all digging positions. The conveyor may be, and preferably is, mounted, at the receiving end thereof, on'an arcuate track supported by the mobile base and adapted to be swung laterally (with respect to said mobile base) about an axis which coincides, or substantially coincides, with the pivotal connection between the table or deck and the mobile base.
The shoveling machine above generally described may be, and preferably is, provided with adjustable means for maintaining preselected relationships between the former and a car or truck. The same may be in the form of an adjustable coupler.
The invention will now be described more specifically and with reference to the accompanying drawings, in which: v 1
Figure 1 is a side elevation of a'mucking machine embodying the principles of the invention Figure 4 is a diagrammatic plan indicating the digging range and relative position of the elements of the machine.
In the following description and in the figures of the drawings, the same numbers refer to the same parts.
In the drawings, the reference numeral I indicates a scoop or dipper, to which latter are attached the rockers 2-2. These rockers 2 form a rigid unit with the scoop and are positioned so that they rock upon guide rails 3-3 and are fashioned with grooves 4--4 within which cradle cables 5-5 and 66 play as the rocker swings. These cradle cables are attached to the rockers 2 by spring pressed bolts |||--|9 and I. The guide rails 3 are made integral with an upper deck 1 which has formed upon it lugs, at 8-9 and 9-9, within the sockets of which the bailed ends of the cradle cables 5 and 6 are placed. Also mounted upon the upper deck I is a motor |2 which, through a train of gears in the housing l3, drives a flanged drum or reel l4. Attached at one end thereof to the drum I4 is a chain l5 which is led around an idle roller I6 journalled in lugs |1 projecting upwardly from the upper deck 1: the chain |5 has its other end fastened to the center part of a yoke bar I6, which latter is framed between the rockers 2. 2a indicates a resilient stop, e. g., a spring carried by the upper deck for stopping rockers 2.
The front end of the upper deck 1 has attached to it severalrollers at l9. These rollers fit and roll within a guide 29, U-shaped in cross section. which guide is made in the form of an are as viewed from above. The radius of this-arc is struck from a point toward the back of the upper deck 1, where a boss 2| is formed in the said deck, and within the boss 2| an anti-friction bearing king pin 22 forms a pivot upon which the entire upper deck 1 (and rockers 2 and scoop I) can be swung by means of the motor 23 through gears within the housing 24 that drive the worm 25 which latter engages the sector of a worm wheel 26. This worm wheel sector 26 is firmly attached to the upper deck I. The extent of lateral swing is limited by lugs 21 and 21, integral with the upper deck I, that come in contact with a lug 28 integral with the lower deck 29.
The motor 23, gear housing 24, and worm 25 with its housing, are attached to or form parts of lower deck 29, and the supporting base or flange of the king pin 22 is fastened to the deck 29 also, as is the arcuate guide 20. The lower deck 29 is so fashioned as to function as a truck frame for the track wheels 39, and within this frame a suitable set of gearing transmits the power of the motor 3| to said wheels 30.
The central part of lower deck 29 is cored out lengthwise of the deck, with an opening 32 of square cross section. The walls of this core, as
p it ends at the back of the deck, are enlarged to form bosses 33, and these latter are drilled to receive a pin 34. Slidably mounted within the square core is the square tubular shank 35 of a coupling 36 which is made flexible at 31. The shank 35 of the coupling is also drilled with a series of spaced holes 39, suitable to receive the pin 34. By means of brackets 39 an operator platform 40 is supported by lower deck 29, and to the same brackets the air control manifold 4| is bolted.
In Figure 1 are shown the several control levers for regulating the action of the various motors, but neither the hose that supplies the air nor the piping that leads to the motors is shown. At the rear of the truck an upward proj egtion of the lower deck 29 terminates in an arc-shaped platform 42 which forms a segmental turntable upon which the pedestal 43 of a boom conveyor 44 rests. The connection of the pedestal 43 with the tumtable platform 42 is so devised with rollers 41, bolts 45, and clamp plates 46, that while the pedestal or base 43 of the boom conveyor is held in contact with and parallel to the turntable top, the pedestal, and with it the boom conveyor, can be tumedthrough a range of are against the predetermined friction that holds the conveyor at the angle set.
The conveyor 44 is provided with a hopper 41 having high side boards 48, at the receiving end, and skirting, at 49, along the remaining portions of the conveyor. The side boards 49 and skirting 49 seal against the endless belt 50 which is supported on rollers 5| and leads around the tail pulley 52. This tail pulley is driven by the motor 53, through gears, chain and sprockets enclosed in the housing 54. At is the head pulley and customary take-up bearings for the endless belt.
A car is shown at 56. The coupling 51 of the car 56 engages the coupling 36 of the mucking machine. The pin 34 in the bosses 33 is equipped with a linkage connection (not shown) which permits the operator to withdraw the pin 34 to a point where it is free of the spaced holes 38 in the shank 35 of the coupling. By using the tension or compression between mucker and car, as the pair advance or retreat from the work, the operator can completely fill the car from end to end by dropping the pin 34 successively into holes of the spaced series 38, which brings the discharge end of the conveyor into similarly spaced loading spots over the car 56.
The operation of the shoveling machine or mucker is as follows: With scoop in lowered or digging position, the mucker, by actuation of propelling motor 3|, is advanced toward and crowded against a muck pile so as to fill scoop with the material. Actuation of motor l2 lifts the loaded scoop to discharge position through the agency of the gears within housing I3, the chain reel |4, chain l5, and rockers 2 rocking upon guide rails 3. At the end of the upward and backward travel of the scoop and scoop-rocking structure, movement of said parts is stopped by the operation of the resilient stop or bumper 2a against rockers 2, material is discharged from scoop I, and the latter descends to lowered, digging, position by gravity when motor I2 is reversed. The stopping point of said travel is substantially over pivot 22, and hence discharged material falls to the substantially same point of reception regardless of the angularity of position of upper deck 1. Actuation of motor 23 serves, through the agency of the gearing in housing 24 and worm drive 25 engaging worm wheel 26, to move upper deck 1 and the parts attached to the latter horizontally laterally with respect to the major axis of the mucker. Similarly, the conveyor system may, in effect, be swung horizontally laterally about pivot 22 while maintaining the center of hopper 41 in substantial alignment with pivot 22. The horizontally lateral movement of the conveyor system may be effected manually or it may, without departure from the invention, be effected by mechanical or power means.
Figure 2 shows the relative position the scoop occupies in the discharge position with the discharge lip formed by the side wall opposite the digging edge disposed lowermost and in overlapping arrangement with the end wall of the conveyor hopper. Figure 3 and Figure 4 show the lateral range in each direction through which the motor 23 is able to force the upper deck I with the rockers 2 and scoop I, to permit of digging to the sides of the track. Figure 4, in particular, brings out the fact that, in any of the positions scoop I might assume in digging, the point of discharge is always back to the common center point located within the hopper 41. This figure also shows the possible movement of the conveyor 44 about the connection to the lower deck, and illustrates how easily this machine could be used to muck around a curve in a tunnel; or, in a double tracked job, could even be used to load a car on the opposite track.
While the invention has been specifically described above with reference to a preferred embodiment of the apparatus, it will be apparent that the invention is not limited to the specific assemblage. Thus, as noted hereinbefore, the mobile base and the car or truck need not operate on a pre-laid track but may operate on its own track (i. e., may be a crawler type of chassis) or may include a rubber-tired chassis. Again, while air motors have been shown for actuating the various parts, it will be apparent that other sources of power might be substituted therefor.
