1459938 Root crop conveying apparatus DEERE & CO 20 May 1974 [21 May 1973] 22366/74 Headings AIF and A1P [Also in Division B8] Apparatus for conveying root crops comprises a vertical auger 135 mounted within a housing 134, the housing 134 having at its bottom end a root inlet 132, a feed conveyor 110 for discharging the roots into the inlet 132, the auger 135 being rotatable for advancing the roots upwardly, and a rotatable root sweeping device mounted in a housing (198) Fig. 2 (not shown) and including a plurality of outwardly extending rotating arms 208, the device being located near the upper portion of the inlet 132 with its axis of rotation substantially horizontal and at the same level as the top 142 of the inlet 132 to maintain the beets within the auger housing 134, in use. The roots are lifted by a root removing unit 52, which comprises a plurality of a cooperating pair of rotatably mounted digger wheels 54 and paddle wheels 58, the wheels 58 being anti-clockwisely rotated by a shaft 60, which in turn is driven by a shaft 82. The paddle wheels 58 deflect the raised roots to an endless conveyor 94 for transferring them to the feeding conveyor 110, which comprises grab rolls 112 driven by shafts 118. An idler (130) Fig. 2 (not shown) is disposed to rotate alternate rolls 112 in the same direction thereby facilitating removal of dirt from the roots. The harvester is connected to a tractor via a hitch 32. The power for driving each of the components is obtained from a take-off power shaft in the tractor via a power shaft 48. The feeding conveyor 110 carries the roots to the auger conveyor 135, which is drivingly connected to a sprocket 156 of the shaft 82 with a bevel gear (158) Fig. 2 (not shown) at the lower end of the auger shaft 152. The roots are then received by a conveyor 182 disposed near the upper end of the housing 134, which conveyor comprises a flexible conveying element 190, drivingly trained around rollers 188 and operated by a pneumatic control 192. The roots are conveyed to an accompanying truck. The root sweeping device is defined by vertical walls 200 and 202 and an arcuate top wall 204 connected to the walls 200 and 202 and the auger housing wall 136. Within the housing (198) Fig. 2 (not shown) of the device is mounted a square shaft 206 which is rotatably supported at opposite ends in bearings 205 and 207. A paddle 208 is connected to each of the flat sides of the shaft 206. Each paddle 208 is composed of resilient member 210 which is also arcuate at its free end in order to lie concentric with the auger wall 136. |
