Referring now in detail to the drawings there i~
i,llustrated in Figure 1, a mobile,self-propelled residue pick-up and processing machine comprising essentially an ' articulated vehicle 100 having mounted thereon a self-- dumping container 200, a residue pick-up and cutting attach-~' 35 ment 300 and a conveyor 400 for conveying the cut-up residu~
from the attachment 300 to the container 200.
ll-f~
The mobile vehicle 100 is a modified version of a common articulated vehicle having respective front and rear chassis 101 and 102 hingedly interconnected at 103 by way of a rigid frame extension 104. The frame extension 104 is rigidly secured to the front chassis 101 and projects rear-wardly therefrom. The container 200 is pivotally mounted, adjacent one edge thereof, on the rigid frame 104 by a pair of trunions 105. One or more hydraulic powered cylinder means 106 is anchored at one end to the frame 104 and at the other to the container 200 for pivoting the same to dump the cut-up re0~due collecte,d'in the container. The front cllassis has an operator's protective cage or cab 107 mounted thereon and in which are located controls 108 for operating the machine.
The power source, not specifically illustrated, is located within the enclosure on the rear chassis 101. The vehicle is a rubber tired vehicle having four wheels 109.
The attachment 300 is pivotally mounted as at 301 on the front chassis 102 and is controllably raised and lowered by a hydraulic piston cylinder unit 302. The residue pick-up assembly of the attachment 300 comprises: a hub 303 (or shaft) journalled for rotation about a horiztonal axis and driven by a pair of hydraulic motors 304 by way of belts or chains 305. A plurality of arms 306 are mounted on the hub 303 at positions spaced circumferentially therearound and longitudinally therealong. The arms 306 are preferably curved forwardly in the direction of the rotation and pass by a plurality of laterally spaced cutting knives 307. The hub 303 is journalled for rotation in opposed side walls 310 of a housing having a top wall 311 spaced upwardly from a bottom plate 308 providng therebetween a passage for the residue.
Residue picked up by the arms, rotating counterclockwise as viewed in Figure 1, enters the passage through a front opening at 312 and is cut into smaller pieces through the co-operation of the rotating arms 306 and the cutting knives 307.
, The knives 307 are detachably connected in any con-venient manner to the bottom plate 308 and the top wall 311 il7~ 5 of the housing. The cutting knives 307 may have a cutting edge that slopes backwardly as illustrated in solid line in Figure 5 or have a straight edge transverse to the channel as illustrated by broken line in Figure 5 and designated by the reference numeral 307a. In addition to the cutting knives 307 in the passage a pair of cutting knives 307b are located respectively at opposite sides of the entry 312 to the pa 5 sage.
An impeller designated generally by the reference numeral 320 for propelling the cut-up residue through the passage is mounted on the housing in proximity of the fixed knives 307. The impeller has a shaft 321 journalled for rotation about an axis parallel to the axis of rotation of the hub 303 of the residue pick-up. The shaft 321 is driven either by a separate hydraulic motor or hydraulic motors 304 by way of belt or chain drive 322. Fixed to the shaft 321 are a plurality of hubs 323 each of which have arms 324 mounted thereon. The arms preferably are pivotally attached to the hubs 323 by, for example, pins 325 and are equi-spaced about the axis of rotation of the shaft. The shaft is rotated clockwise, as viewed in Figure 5, and the arms in sequence enter the passage between the plate 308 and the wall 311 and move to the left, as viewed in Figure 5, before leaving the passage. The arms, in sequence, propel the cut-up residue through the passage and cause it to be discharged through an outlet 313 onto the conveyor 400.
Each of the different sets of impeller arms are covered by an individual guard 326 mounted on the top wall 311 of the housing.
The impeller 320 was found most effective during field tests and substantially eliminated any accumulation of cut-up residue in the passage and thus avoided clogging.
The arms 306 of the pick-up pass through slots 309 in the bottom plate 308. Field test operations also showed that the accumulation of residue in the passage was reduced by fixing cutting knives 350 to the plate 308 at the end or base of the slots 309. The cutting knives 350 have a 117'~1~5 cutting edge located closely adjacent the free end of the arms 306 as they pass through the slot.
The conveyor 400 is a conventional belt conveyor driven to rotate by a hydraulic motor 401. The conveyor 400 is pivotally mounted by a pin 402 on the front chassis 102 of the vehicle and the pivot axis is in axial alignment with the pivot axis of pivots 301 mounting the attachment 300 to the vehicle. The conveyor 400 is raised and lowered by one or more hydraulic piston cylinder units 403 connected in any convenient manner to the chassis 102 and the conveyor.
