Still further, the shower head sets up downwards, just the contained angle of shower head and bellmouth inclined plane is 45 degrees to prevent that the rivers that the shower head spun from splash everywhere.

Furthermore, the valve is an electromagnetic valve, the electromagnetic valve is connected with the output end of the delay relay, and the input end of the delay relay is connected with the controller of the weighing belt feeder.

Furthermore, a flow regulating valve is arranged on the water supply pipe and is positioned between the valve and the water supply device.

Furthermore, a flowmeter is arranged on the water supply pipe and is positioned between the valve and the flow regulating valve so as to facilitate the auxiliary flow regulating valve to regulate the flow in the water supply pipe.

Furthermore, a booster pump is arranged on the water supply pipe and is positioned between the flow regulating valve and the water supply device.

Compared with the prior art, the utility model has the advantages of it is following:

the utility model prevents the feed pipe from being blocked by adding the spray head in the feed pipe and washing the baits adhered to the feed pipe, the water supply of the spray head is controlled by the electromagnetic valve, and the electromagnetic valve realizes the synchronous work with the weighing belt feeder through the time delay relay, thereby avoiding the trouble of artificial frequent control; the utility model discloses set up flow control valve, can adjust the flow in the ring channel to the water yield that effectual control sprayed.
