, In Sweden July 20, 1940 4 Claims. 401. 198-9) The object of 'the present'inventidn'is to'pro vide a simple '-andeasily"operated collecting or loading machine; particularly for granular material, which-isals'obheap in operation but ofgreat capacity. and" which can be used withlnvery different spheres orwor'k without" considerable reconstruction.
Another object of the invention is to provide a machine-in which-the'el'm'ents subjected to the most violent wearing are very cheap and easily exchanged.
The above specified and other objects are accomplished, according to the invention, by the arrangement and combination of parts set forth in the following detailed description, defined in the appended claims and illustratively exemplifled in the accompanying drawings, in which Fig. 1 is a side elevation of the collecting machine,
Fig. 2 is a plan view of the same,
Fig. 3 is a plan view of a detail, and
Fig. 4 is a larger scale sectional view of a detail taken on the line IV-IV in Fig. 2.
Referring to the drawings, numeral l indicates a vehicle frame carried by wheels 2. In case the vehicle is to be driven over a difficultly trafiicable ground the same is preferably provided with endless chains. At one end of the frame I two arms 5 are pivoted on a shaft 4, said arms Sat one end carrying a guide roller 6 for an endless conveying belt l' as well as two arms 9 united with a ring 8. The other ends of arms 5 are provided with, or formed as, toothed segments 19, which are in mesh with toothed wheels ll fixed to a shaft I3, the turning of said shaft by means of a crank l2 consequently ,causing the arms 5 to rock. The latter and the toothed segments 10, of course, may be fixed to the shaft 4, the latter being in such case rotatably mounted. With the ring 8 there are also flexibly united two arms 14, the other ends of which are provided with guide slots l5. Said guide slots are engaged by suitable clamping means [=3 secured to the vehicle frame and ada ted to the arms in the desired position relatively to the vehicle frame.
To the ring 8 there are secured suitably spaced rollers !'l engaging a guide groove I9 in a ring I8 (Fig. 4) The latter is fixed to the underside of a flat plate 20 having a continuously curved outer edge and the outer circumference of the ring I8 is provided with teeth 2i. which are in mesh with a motor driven toothed wheel not shown on the drawings. The plate 20, which has a central circular opening 22, is provided on its upper surface with vanes 23, which are arranged at an inclination to the plate: Each =vane 2dextends for; a little more than half of its le'ngth along the outer edgeof'thefplate' and has an inwardly curved portion meeting the opening 22 on a; substantially tangential line (Figf3l'; Froin 'thedrawing it willbe clear that the height ofthevanes successivelydecreasesftowards the outer edge of the plate; In' the'lowerjhalf of the openingofj the plate there "is provided a'chute 24 "ofsemi-circular cross section, which is rigidly secured to the ring 8, and the lower end of which is preferably provided with an elastic downward extension 24a, bearing on the belt I or adapted to be pressed against the same.
According to the illustrated embodiment there is a second endless conveying belt 26 carried by a turnable arm 25. By means of a crank 21 and a worm gear 28 said arm may be adjusted to the desired position, whereby the material falling down from the belt I on the belt 26 is transported to receptacles behind or laterally of the collecting machine. The conveying belts 1 and 26, the plate 20 and the driving wheels of the vehicle may preferably be driven by the same motor, and they may all be adjusted while the machine is in operation.
The machine operates as follows:
After the machine, with receptacles, if any, connected thereto, has been drivento the place of work, the disc 20 by means of, crank I2 is adjusted to a suitable height and by means of the clamping means I6 fixed in a suitable inclining position. (These adjusting means are easily operated even during work, the greatest efiiciency of the machine being thereby obtained.) The plate 20 isnow put into rotation, and because of the shape of the vanes 23 the machine will, so to say, out its way into the material in ques tion, which is carried up at a level with the opening 22, into which the material falls down owing to its own gravity. Since the inner ends of the vane 23, when moving upwards, tightly bear on the outer side of the semi-circular chute 24, which may be provided with an exchangeable fitting, no material. can fall back again but is positively carried upwards until it falls down into the opening 22 or on to the chute 24. The
downward extension connected with this chute ensures that no part of the material elevated by the vanes 23 can fall down on to the ground, all
material being at once conveyed by the belts and 26 to the respective receptacles, the arm 25 being adjusted so that the material falls down into the correct receptacle. The collecting machine may be moved from one place to another and operatin elements may be adjusted without any interruption of the work being necessary.
As already mentioned, the machine is particularly intended for granular material, such 7 as coal, ore, gravel and the like, but it may also be used with advantage for collecting other materials. Thus, it may be used also for peat, the device inthis case,' if the vanes 23 are suitably shaped, being able to attack the ground directly. Several embodiments are possible, of course, within the scope of the invention, the nature of the material to be collected to a great extent determining in what manner the device is to be modified.
Having now described my invention, what I claim as new and desire to secure by letters patent is: 1. In a, collecting machine, particularly for granular material, having a frame, a rotatable flat plate obliquely positioned on said frame, said plate having a continuously curved outer edge and being provided with a central substantially circular opening, a. conveyor disposed beneath said opening, the combination of at least one ing portion meeting said opening on a substantially tangential line, and a stationary chute of semi-circular cross-section projecting through the lower half of the opening of said plate, said chute being adapted to catch the material falling down from the plate and to direct it to the conveyor.
2. Collecting machine as claimed in claim 1, in which the height of the vane gradually decreases towards the outer edge of the plate;
3. Collecting machine, as claimed in claim 1,
. including an elastic downward extension of said -chutelbearing on said conveyor.
4. In a-collecting machine, particularly for granular material, having a frame, a rotatable flat plate obliquely positioned on said frame and carrying curved collector vanes, and an endless I .belt conveyor beneath a central opening in said upstandingcurved vane on the upper surface of said rotatable plate, said vane extending for approximately half of its length along the outer edge of said plate and having an inwardly curvplate, the combination of means for rotatably supporting said plate on said frame, said supporting means comprising a circular guide groove provided on the underside of said plate, a ring carrying a plurality of rollers adapted to engage said guide groove for guiding and centering said plate, arms rigid with said ring and adjustably pivoted to said frame, and a guide roller for said endless belt conveyor carried by said arms.
