Description

Technical Field

[0002] Usually, aquaculture uses feeding machines. Existing feeding machines set the feeding amount according to the feeding time. This method of timing and controlling the feeding cannot accurately control the feeding amount. Chinese patent 201510047161.0 discloses a retractable feeding machine base, which uses four triangular boxes, each of which is equipped with a weighing module, that is, four weighing modules are required to form a metering unit. The entire feeding machine is a metered unit, but what really needs to be measured is the feed in the feeding machine. Usually, the weight of the feeding machine will be greater than the weight of the feed, especially before the feeding is about to be completed. The metering error will be very large. If the feeding machine is equipped with a feed pipe, it cannot be used at all. In addition, four weighing modules are required, which is too costly. Summary of the invention

[0006] The feed pipe of the feeding machine is connected to a multiplexer, and the multiplexer is provided with a feed port and a plurality of discharge ports. The feed port is communicated with a rotatable elbow feed port, and the discharge port of the elbow can be communicated with a plurality of discharge ports. The plurality of discharge ports can be provided with feed branch pipes leading to feeding points of each breeding pond. The feeding machine with a precise feeding mechanism can set the feeding amount according to the needs of each feeding point, and can realize precise feeding to each breeding pond in turn; if the feed required by each breeding pond is different, different feeds can be loaded in containers with precise feeding mechanisms, and the feed pipes of the feed receivers of the containers with precise feeding mechanisms are connected to the same pipeline, and the feed variety, feeding amount and feeding time required by each breeding pond can be controlled by PLC programming.

[0007] The feeding pipe is communicated with the hollow shaft of the throwing mechanism, and the hollow shaft includes the hollow shaft of the outer rotor motor. The throwing device is connected to the rotor of the outer rotor motor and rotates together with the rotor when working, and the hollow shaft does not rotate. The feed blown by compressed air enters from one end of the hollow shaft and is thrown out from the throwing pipe of the throwing device.

[0008] A throwing device for aquaculture mainly comprises a motor, a throwing tube and a mounting seat, wherein the mounting seat is provided with evenly distributed holes, the throwing tube is obliquely arranged in the holes, the flange of the throwing tube is against the inner side of the oblique hole or the throwing tube and the mounting seat are welded together; the mounting seat is provided with a feeding port, and the mounting seat is connected to the motor shaft; a disc capable of reducing air resistance is arranged outside the throwing tube, the disc is composed of at least two parts, the throwing tube is arranged inside the disc, and a discharge port is arranged outside the throwing tube, which is flush with the disc or slightly exposed from the disc; when working, the motor drives the throwing tube and the disc to rotate, and feed is thrown into the fish pond under the action of centrifugal force; the disc can be formed by injection molding or aluminum die casting.

[0009] The disc is composed of an upper disc and a lower disc, and there is a mounting position for a material throwing tube between the upper disc and the lower disc. After the upper disc and the lower disc are connected, the material throwing tube can rotate together with the disc in the disc; the lower disc is a conical structure with a high periphery and a low middle. The middle part of the lower disc is arranged on the flange of the motor shaft, and the mounting seat is arranged on the middle part of the lower disc. The mounting seat and the lower disc are fastened together on the flange of the motor shaft by screws; or the mounting seat and the lower disc are fastened together on the rotor of the outer rotor motor by screws.

The feed sent by the remote feeding machine by wind enters the lower end of the disc from the hollow shaft of the motor shaft and enters the throwing device, and is thrown from the throwing pipe to the water surface to feed the fish.

[0013] The material distribution speed of the material distribution mechanism is slower than the speed at which the rotating piece of the feed receiver brings the feed to the lower side of the feed receiver and enters the feed conveying pipe, so that the feed cannot fill the space in the feed receiver during the working process of the feed receiver, which can effectively prevent the feed from being blown back.

[0014] The outstanding advantages of the present invention compared with the prior art are: The three components of the material distribution mechanism, the connecting seat, the loading container and the feed of the present invention form a metered unit, in which the weight of the feed is the main one, and the weight of the other three components accounts for a smaller proportion. The other components of the feeding machine are not within the metered range, so the metering is accurate. A gravity sensor is installed at the bottom of the lower conical container, which has a simple structure, low cost and is convenient for mass production. The present invention also overcomes the technical problem that the motor load increases due to air resistance when the throwing tube rotates. BRIEF DESCRIPTION OF THE DRAWINGS

When the material distribution mechanism is working, the separated feed falls into the throwing mechanism and is thrown into the breeding pond; the material distribution mechanism does not contact the throwing mechanism, and when the feed in the container 1 is gradually reduced to the set weight when the material distribution mechanism is working, the material distribution mechanism stops distributing the feed, and the feeding machine stops working.
