1,139,420. Unloading agricultural trailer. AMAZONEN WERKE H. DREYER. 11 May, 1966 [21 May, 1965], No. 20912/66. Heading B8E. [Also in Division A1] A machine for transporting and discharging powdery granular materials comprises a storage container with a platform bottom, and a power driven endless conveyer having spaced scraping bars arranged to move rearwardly along the platform bottom to convey the material, through a discharge slot, to the rear edge of the bottom, the rear edge and the scraping bars being mutually inclined. As illustrated the machine which is tractor drawn comprises a hopper 2 having a bottom 3 the rear edge of which is V-shaped in plan whereby an endless slat conveyer 6 conveys material to a transverse trough 39 positioned below the V-shaped portion and containing transverse augers 40, 41 which convey the material via adjustable apertures 42, 43 to spinner discs 56, 57. Positioned above and extending on to the rear edge of the hopper bottom are flaps 30 which prevent escape of material until they are disturbed in operation by the conveyer slats. The rear wall of the hopper includes a vertically adjustable plate which enables the discharge gap (35), (Fig. 2, not shown) to be varied. The conveyer, augers and discs are driven from the tractor p.t.o. shaft via gear-boxes (16, 65), (Fig. 1, not shown) and clutches (70, 69). The discs may be replaced by a transversely disposed endless conveyer (51), (Fig. 5, not shown), and the trough may be covered by a baffle plate. |
