摘要：
The distributor is esp. for granular material e.g. seed or fertiliser, having a pneumatic metering feed mechanism from the storage hopper to the head. Pipes from the latter deliver to a sowing share or fertiliser spreader. Some of these pipes have stop valves cutting off the supply to the spreader etc. the material being then returned by pipe to the hopper. The return pipe (16) leads to a point above the metering mechanism (2), where this extracts the seed from the hopper (1). The pipe mouth (17) can be so situated that mostly the returned material is extracted. All the return pipes from the stop valves can lead to a collector, from which a common pipe leads back to the hopper. The valves can consist of deflectors movable between two positions. In one of these, all pipes to the shares are open, while in the other they are connected to the return pipe.
