Title: Improvements in or relating to apparatus suitable for distributing fertilising or like material on the ground
IPC: A01C15/10
Filed: 1944-05-26
Abstract: 594,230. Manure distributers. POMIERANIEC, I., and TRANSPLANTERS (ROBOT), Ltd. May 26, 1944, No. 10254. [Class 6 (i)] Relates to fertiliser distributers of the type wherein reciprocating apertured plates 16 oscillate between sets of staggered apertures in the base 7 of a hopper 6, containing fertiliser, and in a platform 12 located beneath the hopper. According to the invention, the rate of distribution of the fertiliser is variable by raising and lowering the container with respect to the platform. In the form shown, the hopper 6 is supported on a wheeled chassis by means of angle iron girders 3 secured to transverse frame members 1. Below the base is an apertured platform 12 supported on girders 13<SP>1</SP> also secured to the frame members 1, the apertures in the platform being staggered with respect to those in the base. The space between the platform and the base is occupied by apertured plates 16 which reciprocate so that their apertures register alternately with those in the base and in the platform. The reciprocation is derived from the land-wheel axle 3 through a cam 29 formed with worm-like grooves 27, 28 with which the lower ends of rocker arms 17, 18 engage, the arms having enlarged heads 23, 24 located within slots in the sliding plates. The drive between the axle 4 and the cam includes a clutch 54. The cam also drives an agitator 35 within the hopper, as described in detail in Specification 586,444. The rate of feeding of the fertiliser is variable by altering the separation between the base 7 and the platform 12 thus allowing the material to build up on the sliding plates to a variable extent. The hopper is therefore supported upon pins 51, (see Fig. 8), on a subsidiary frame 3<SP>1</SP>, the pins being mounted upon interconnected pivot links 47 and being raisable in unison by the action of a lever 53. Further control of the rate of feeding may be provided by the addition of outlet plates of various sizes to the apertures in the platform 12. Specification 594,231 also is referred to.
