(54) CROP GATHERING APPARATUS
(71) We, MASSEY-FERGUSON
PERKINS LIMITED, a British Company, of 33 Davies Street, London, W1Y 2EA, and
ROBIN JAMES THOMPSTONE, of
British nationality, of Cherry Tree Farm,
Warmington, near Banbury, Oxfordshire, do hereby declare the invention, for which we pray that a patent may be granted to us, and the method by which it is to be performed, to be particularly described in and by the following statement: This invention relates to crop gathering apparatus and in particular to such apparatus comprising a table to receive cut crop, said table defining the gathering width of the crop gathering apparatus, attachment means on the table whereby the table may be mounted on a harvesting vehicle, and a crop conveying belt mounted on the table and positioned in the gathering width of the table.
It has been proposed to provide crop gathering apparatus in which endless crop conveying belts or canvasses have been provided with transverse wooden slats fastened to their crop conveying surface. These wooden slats have served two purposes. Firstly, they have provided crop conveying formations to assist the belts in carrying the crop, by reducing slippage of the crop relative to the belts. Secondly they have served to guide the belts so as to reduce the inherent tendency of the belts not to run straight and to run off the rollers around which they are trained. This latter function of the slats has been achieved by providing a fixed vertical guide surface against which the ends of the slats run.
However crop conveying belts as described
in the preceding paragraph have not been
entirely satisfactory, particularly as regards the
use of the slats to guide the belts.
Belt guidance techniques applicable to con
ventional belt conveyor systems are not readily
applicable to crop conveying belts in grain crop gathering apparatus due to the design
parameters imposed by the crop and the
gathering apparatus itself. Examples of such
parameters are the desirability of a fiat crop conveying surface and stringent limitations on available space.
In British patent 1,501,639 there is disclosed crop gathering apparatus comprising a crop conveying belt having belt guide means comprising a pair of adjustable guide rollers.
An object of the present invention is to provide such apparatus having simplified belt guide means.
According to the invention there is provided crop gathering apparatus suitable for use in harvesting grain crops, said crop gathering apparatus comprising:
a table to receive cut crop, said table defining the gathering width of the crop gathering apparatus;
attachment means on said table whereby the table may be mounted on a harvesting vehicle;
a crop conveying belt, said belt being mounted on said table and positioned in the gathering width of said table so as to convey cut crop;
end rollers for said crop conveying belt, said end rollers being mounted for rotation at positions spaced apart in the direction of operative forward motion of the crop gathering apparatus and said belt being trained round the rollers in an upper run and a lower run; and,
drive means for said crop conveying belt, said drive means being capable of driving said belt so that said upper run moves, relative to the table, rearwards having regard to said direction of operative forward motion of the crop gathering apparatus;
wherein interengageable first and second belt guide means are provided, the first belt guide means comprising a first guide element secured to the underside of the crop conveying belt, and the second belt guide means being fixed laterally with respect to said direction of operative forward motion of said crop gathering apparatus and engaging into said first belt guide element to positively restrain the belt against movement in both lateral directions.
An embodiment of the invention will now be described by way of example with reference to the accompanying drawings in which: Figure 1 shows a perspective view of crop gathering apparatus in the form of a table for a combine harvester;
Figure 2 shows a section through a crop conveying belt and an end roller therefor, forming part of the crop gathering apparatus, the section being taken in the plane II--II indicated in Figure 1; and
Figure 3 shows, in a sectional view similar to Figure 2, a further embodiment of the invention, the belt being shown clear of the roller for illustration purposes.
As shown in Figure 1, a crop gathering apparatus 10 comprises a table 12 to receive cut crop, a reel (not shown), crop cutting means in the form of a cutterbar 16, crop conveying apparatus 18 and an auger 20.
The crop gathering apparatus is mounted at the front of the main body (not shown) of a self-propelled combined harvesting and threshing machine, or combine. The main body is mounted on steerable rear wheels and driven front wheels and constitutes a harvesting vehicle. The main body houses an engine and conventional grain crop threshing and separating apparatus such as a threshing cylinder and concave, straw walkers and a shaker shoe. The main body also provides a grain tank and an operator's platform.
Table 12 is mounted on the housing 22 of a conventional chain and slat elevator 24.
Elevator housing 22 is pivotally mounted on the main body of the combine at its rear end, in the usual manner, and hydraulic rams (not shown) are provided to raise and lower its forward end relative to the main body. The forward end of the housing has conventional attachment means (not shown) whereby table
12 is mounted thereon so as to be quickly detachable.
Table 12 has end walls 26, 28 defining the crop gathering width 30 of the table, and each end wall has a forwardly sloping front edge providing crop dividers 32, 34.
The reel (not shown) is of conventional construction, having tines and a mechanism for maintaining the tines in a downwardly projecting attitude as the reel rotates. The reel is mounted on support arms which are pivotally connected to the table whereby the reel can be raised and lowered by means of hydraulic rams in the usual manner. The reel can also be adjusted in the fore and aft direction along its support arms in the usual manner.
Cutterbar 16 is also of conventional form.
Crop conveying apparatus 18 comprises three crop conveying belts 36, 38 and 40 arranged side by side across the crop gathering width 30 of the table 12.
Auger 20 comprises a central shaft in the form of a sheet metal tube 42 and two helical flights 44, 46 mounted on the tube at opposite ends thereof. Flights 44, 46 are of opposite hand and spaced apart by a central portion 48 of the tube from which a series of crop feeding fingers 50 project. The fingers extend, feather and retract in the usual way as the auger rotates, to feed crop to elevator 24 through a rectangular opening 52 formed in the rear wall 54 of table 12 just below the main table support beam 56.
The three crop conveying belts 36, 38, 40 are each trained round their own pairs of spaced-apart end rollers 58, 60 in an upper run 62 and a lower run 64. Each end roller extends across the full width of its own belt 36, 38 or 40 and the end rollers of each pair are mounted for rotation at positions spaced apart in the direction F of operative forward motion of apparatus 10. Drive means in the form of a chain and sprocket drive (not shown) connected to rear rollers 60 is provided so as to drive the upper runs of the belts rearwards relative to table 12, having regard to direction
F as indicated by arrow D.
Four profiled sheet metal covers 66 are provided to cover the gaps between the belts 36, 38, 40, and the gaps between the belts and end walls 26, 28. The covers each have a roofshaped cross sectional shape.
Means (shown in Figure 2) is provided for guiding each of the belts 36, 38 and 40 so as to maintain each belt in its correct position along the length of its end rollers 58, 60 i.e.
to centralize each belt and ensure that it runs straight and does not move sideways. Figure 2 shows an axial cross section through one of the front end rollers 58 and through its associated belt 38. The corresponding rear end roller 60 is similarly constructed and arranged. The arrangement is the same for belts 36 and 40.
Belt 38 and roller 58 are each provided with two pairs 70, 72 of interengageable first and second belt guide means, one pair at each of two positions spaced apart along the gathering width 30 of the crop gathering apparatus 10 and along the rotation axis 74 of roller 58.
In the pairs 70, 72 of interengageable first and second belt guide means, the first belt guide means comprises respective first guide elements 76, 78 secured to the underside of belt 38 in the region of its two side edges, and the second belt guide means comprise respective annular grooves 80, 82 formed in roller 58 to receive guide elements 76, 78, the grooves thus being fixed with respect to roller 58 in the lateral direction having regard to direction F.
The first guide elements 76, 78 are each in the form of continuous moulded and vulcanized rubber ribs formed during manufacture of the belt. Each rib tapers towards its apex and the grooves 80, 82 similarly taper towards their bases so that the ribs fit the grooves.
In use, ribs 76, 78 and grooves 80, 82 (and the corresponding grooves in rear end rollers 60) keep belts 36, 38, 40 in the desired positions on the rollers at all times and prevent the belts wandering laterally. The belts feed crop from cutterbar 16 to auger 20.
In the embodiment of Figure 3, belt 84 is formed with a single continuous central rib 86 and end rollers 88 have a single central groove 90, and the apparatus operates as described above.
The advantages provided by the embodiments described above include the simplicity of the belt guidance means, its low weight and low cost and the fact that it requires no adjustment.
Among modifications which would be made in the above-described embodiments which nevertheless fall within the scope of the invention are the following: 1. the use of interrupted or discontinuous first guide elements;
2. the use of plastics material for the first guide element;
3. the use of a length of vee type drive belting secured (by bonding for example) to the underside of the belt in place of an integrally moulded rubber rib;
4. the use of other first guide elements such as roller chain or wire rope, suitable secured to the belt, for example by rivetting;
5. the use of other second guide elements such as a rotatable pulley wheel (to co-operate with a wire rope), or a rotatable sprocket (to co-operate with a roller chain), or an end roller having two laterally spaced portions defining a gap between them to receive any suitable first guide element.
