Description

(52) "BALE CHUTE" (71) We, ERNEST BRIAN LITHERLAND and MARK WILLIAM LITHERLAND, British Subjects both of Birch House Farm, Sinderland Road, Dunham Massey, Cheshire, 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 a bale chute for use in stacking bales of hay.
A known method of stacking bales of hay on a trailer drawn behind a tractor-driven baling machine involves the use of an upwardly inclined slide or chute fixed to the outlet of the baling machine. The baling machine forces bales from the outlet and up the chute in continuous contiguous succession. At the top of the chute it is usual for the bales to be removed one at a time manually and deposited at the appropriate positions on the trai]er therebeneath.
With this arrangement two main disadvantages may arise.
Firstly, in so far as the bales have to be removed manually from the top of the chute and then have to be arranged on the trailer it will be appreciated that much manual work is involved normally by two or more persons and it is usually necessary to provide steps or the like to give access to the top of the chute. If the bales were allowed to fall from the top of the chute rather than being removed manually one person would not normally be able to keep up with the rate of feed of the bales at the normal operational rates of known baling machines.
Secondly, due to the fact that the bales are pushed up the chute in continuous contiguous succession it is possible that the bales may become undesirably misshaped.
An object of the present invention is to provide a bale chute with which the above mentioned disadvantages can be avoided or at least appreciably reduced.
According to the present invention therefore there is provided a bale chute adapted to be mounted on a baling machine at the rear thereof, said chute comprising an upwardly inclined bale-guiding passageway having a lower end arranged when mounted on a baling machine to receive bales one at a time from an outlet of the baling machine, power drive means extending in said passageway along the whole length thereof, said power drive means comprising a drivable elongate member having gripping means thereon adapted to grip bales fed to the lower end of the passageway and to draw some individually up the passageway in a direction in line with that in which the bales are received from the said outlet of the baling machine, and an outlet at the upper end of the passageway to which the power drive means is arranged to deliver said bales drawn up the passageway such that said bales are arranged to fall downwardly one at a time at said outlet in line with said direction.
With this arrangement, in so far as the bales are drawn individually up the passageway it will be appreciated that a continouus succession of such bales as discharged from the baling machine outlet can be disrupted whereby they may be ejected from the outlet of the passageway at intervals sufficient to allow one person to arrange one bale at an appropriate position, for example on a trailer beneath the outlet before next bale is ejected from the outlet. An appreciable saving in labour can therefore be achieved. It is also not necessary to provide steps or the like to give access to the top of the chute.
Further, due to separation of bales and power drawing of same up the passageway it will be appreciated that there is little tendency for the bales to become mis-shaped. Stacking of bales is also rendered much more convenient since the passageway is not completely filled with bales in use which facilitates control and manoeuvrability of the equipment.
The passageway may comprise a skeleton framework having bottom longitudinal members along which the bales can slide and also side members and possibly also top members for guiding and/or strengthening purposes.
Appropriate guides such as angled members and/or rollers or the like may be provided at one or both ends of the passageway to facilitate easy movement of the bales in to and/or out of the passageway.
With regard to the power drive means, this preferably comprises an endless chain preferably having its upper run along the bottom of the passageway and provided with projecting teeth or the like for gripping the bales. The power may be obtained from a hydraulic motor which con veniently may be driven from a tractor hydrau lic system via an oil cooler if necessary. Alter natively an electric motor may be used.
The invention will now be described further by way of example only and with reference to the accompanying drawings in which: Figure 1 is a diagrammatic sectional view of one form of a bale chute according to the in vention in use; Figure 2 is a perspective view of a component of the chute to an enlarged scale; and Figure 3 is a perspective view of part of the chute to a different enlarged scale.
The bale chute is used in conjunction with a conventional tractor-drawn baling machine which in use forces a continuous contiguous succession of bales of hay from a discharge outlet 1 onto an outlet channel 2 which has guide rails 2a at the sides thereof (only one is shown in Figure 3). The outlet channel 2 is provided with a linkage 3 for connection to a trailer 4 whereby such trailer 4 can be drawn behind the baling machine.
The chute is fixed to the baling machine so as to extend upwardly over the trailer from the end of the channel 2.
The chute comprises a passageway defined by a skeleton framework consisting of a number of spaced square frames 5 and a number of parallel elongated members extending within the frame 3 and welded thereto. The elongated members include corner members 6, bottom members 7, side members 8 (omitted from Figure 3) and a top member 9. The members 6 - 9 extend within and are welded to the frame 5 to give a rigid structure.
The bottom of the lower end of the passageway is secured to the end of the channel 2 via a hinge joint 10 and s strut arrangement is secured to the baling machine outlet 1 and to the middle region of the passageway to hold the passageway in the upwardly inclined position shown in the drawing. The strut arrangement comprises hollow square section metal members 20 which are pivotally connected at their upper ends 21 to opposite sides of the passageway and which are rigidly interconnected adjacent their bottom ends by a cross-bar 22. Slide bars or rods 23 fit slidably within the members 20 and are pivotally connected at their lower ends to the baling machine. A hydraulic ram 24 is pivotally connected to the baling machine and to the cross-bar 22. With this arrangement, by actuation of the ram, the inclination of the passageway can be adjusted. If desired the strut arrangement may be of a detachable nature so that the passageway can be hinged down for example for storage or maintenance purposes.
At each end of the passageway there is rotatably mounted a respective toothed wheel 11, 12 and an endless roller chain 13 is engaged with these so that the upper run of the chain 13 runs over the bottom members 7. A detachable cover 13a protects the lower run of the chain beneath the members 7. Spaced teeth 14 are secured to the chain 13 and project therefrom, as can be seen in Figure 2 the teeth are defined by spiked metal members 14a mounted on individual rollers 14b. The lower wheel 11 is connected directly, or via a gear arrangement if necessary, to an electric motor 15 mounted on the side of the chute. Alter natively the motor 15 may be a hydraulic motor which may be connected to the tractor hydrau lic system so as to be powered thereby. The ram 24 may be powered in the same manner.
The top member 9 of the passageway projects at each end of the passageway and is angled outwardly at each such end 9a, 9b.
In use, bales 16 are forced slowly along the channel 2 towards the lower end of the passage way, and the chain 13 is rotated on the wheels 11, 12 by means of the motor 15 so that the upper run thereof moves upwardly at a faster rate that the feed rate of the baling machine.
As soon as the leading end of a blade 16 is pushed onto the bottom end of the passageway such bale is drawn up the chute by engagement of the teeth 14 with the bale. The angled lower end 9b of the top member 9 guides movement of the bale into the passageway.
The bale is drawn up to the top of the passageway well before the next bale has been pushed onto the lower end of the passageway.
At the top of the passageway the bale is ejected over the end thereof by the driven chain 13. The top wheel 12 may be positioned behind a top cross-bar of the passageway so that the bale slides over this cross-bar as it is ejected whereby separation of the bale from the chain 13 can be ensured. Such top cross-bar could be in the form of a round bar or roller if desired.
Sticking of the bale at the top end of the passageway is prevented by the angled upper end 9a of the member 9.
With this arrangement it will be appreciated that the bales are drawn one at a time up the passageway and therefore the rate of ejection of same from the top thereof can be sufficient to enable one person working alone below the chute to stack the bales easily and conveniently on the trailer.
It is of course to be understood that the invention is not intended to be restricted to the details of the above embodiment which are described by way of example only.
Thus for example if desired the chute may have a short extension at the top end of the passageway, said extension extending horizontally or being only slightly downwardly inclined.
Such extension may have a drive chain at the bottom thereof or alternatively no drive device may be provided within such extension. The extension may be of a telescopic nature so that the length thereof can be adjusted and a hydraulic ram or the like may be provided for effecting such adjustemnt.
