2results about How to "Control feeding speed" patented technology

This utility model relates to the field of feed feeding technology, providing a feeding device suitable for the initial feeding of fish fry in factory-farmed aquaculture. The device includes a base, a feed storage bin, a spotlight, a conduit, a suction pump, and a particle detector. The feed storage bin is located on the base and holds the feed; the spotlight has a through-hole; the first end of the conduit connects to the feed storage bin, and the second end of the conduit connects to the spotlight through the through-hole; the suction pump is located in the conduit and is used to draw feed to the through-hole; the particle detector is located in the conduit and is used to detect the amount of feed flowing through. This utility model, by setting up a feed storage bin and a spotlight connected by a conduit, allows feed to flow through the conduit to the through-hole; the suction pump in the conduit regulates the flow rate of the feed to control the feeding speed; and the particle detector accurately detects the amount of feed flowing through, improving feeding accuracy and benefiting the fry rearing stage; it can control the feeding speed and quantity, reduce labor costs, make operation more convenient, and improve the survival rate of fry rearing.

This utility model discloses a feeding mechanism for molding sand production, relating to the technical field of feeding mechanisms. A feeding assembly is fixedly installed on the upper surface of the top of four support plates. A feeding pipe is fixedly installed on the lower surface of the feeding assembly, and a feed hopper is fixedly installed on the upper surface of the feeding assembly. A guide pipe is fixedly installed on the right side of the feed hopper, and an elevator is fixedly installed at the right end of the guide pipe. This utility model uses a motor to drive a rotating shaft and an auger to rotate, lifting the sand inside the machine body into the guide pipe. Simultaneously, the rotating shaft drives the auger to rotate, breaking up any clumps of sand. A feeder facilitates replenishment by the elevator. A motor drives a rotating shaft and an auger to rotate, conveying the sand from the right side of the machine body into the machine body. Simultaneously, the cutting blade on the rotating shaft rotates to cut large pieces of sand, preventing blockages during sand feeding, reducing cleaning workload, and improving work efficiency.
