32results about How to "Avoid uneven feeding" patented technology

The invention discloses a feeding mechanism with a culturing cage and a feeding through in a separated mode. The feeding mechanism comprises a culturing cage which extends along a length direction and is provide with a plurality of feeding mouths for animals to feed, at least one food groove corresponding to the feeding mouths, at least one feeding hopper for adding feeding to the feeding groove, a bearing mechanism for bearing the feeding groove, a driving mechanism for driving the bearing mechanism to make reciprocating movement along with the length direction of the culturing cage, and at least one feeding groove can correspond to all the feeding mouths within one reciprocating cycle. The feeding mechanism has the advantages of being low in production cost, increasing animal feeding, avoiding uneven feeding and the like.

The invention provides a pig house automatic feeding device and a method and a matched pig house. An X-direction driving motor, an X-direction transmission mechanism and a movable cross beam are arranged at the top part of a bracket of the pig house automatic feeding device; the movable cross beam is provided with a Y-direction driving motor, a Y-direction transmission mechanism and a Z-directiondriving motor; a feed thrower is connected with the Z-direction driving motor by a Z-direction transmission mechanism in a transmission manner; a first sensor is arranged at the top part of the feed thrower; a second sensor, a feed throwing driving motor and a feed throwing valve are arranged at the bottom part of the feed thrower; and the feed throwing driving motor controls the opening and closing of the feed throwing valve so as to throw feed into a feed groove. A controller receives sensing signals output by the first sensor and the second sensor, and controls the X / Y / Z-direction driving motors and the feed throwing driving motor to finish the automatic feeding process. The invention effectively increases the pig raising efficiency and lowers the labor intensity of raising personnel. The pig house quantitatively throws the feed to the pig at fixed time, which avoids non-uniform feeding of the pig and reduces injuries of the pig due to fighting.

The invention belongs to the technical field of sturgeon breeding methods and provides a sturgeon fry breeding method. The method involves a flowing water type tank, an initial stocking method, feeding of starter feed, breeding in separate tanks, feeding of feed in a domestication manner, a preparation method of the domestication feed and the like. The sturgeon fry breeding method has the benefits as follows: fish fries weighing 100 g or below are subjected to initial stocking and breeding in separate tanks according to five levels of weights, so that fish fries can grow in a balanced manner, feeding non-uniformity is avoided, and the situation that fishes die of weakness is avoided; targeted segmentation feed is adopted for level-by-level domestication, and accordingly, the fish fries can adapt to fed materials step by step, and the adaptability is improved; Chinese herbal medicines are added to the feed, and the physiques of the fish fries can be improved; a good rehabilitation habit can be formed by adopting a proper water changing rate, dissolved oxygen, breeding density, temperature and illuminance; the flowing water type tank is adopted, oxygen is introduced while water is input, the dissolved oxygen is increased appropriately, dirt at the bottom of the tank can be discharged during water drainage, and the water in the tank can keep clean; the physiques of the fish fries can be effectively improved, and the survival rate is increased with a series of methods.

The invention discloses a feeding device for aquaculture, which belongs to the technical field of aquaculture. The device comprises: a feeding barrel and a feeding boat, the feeding barrel is fixedly connected with the feeding boat through a connecting arm; the feeding barrel includes a barrel body, a feeding pipe and a feeding device, and the The top of the feeding barrel is provided with a feeding port, the feeding port penetrates into the interior of the feeding barrel, the feeding pipe is fixedly arranged at the lower end of the barrel body, and the feeding pipe penetrates to the barrel body Inside, the lower end of the feeding tube is provided with a spherical cavity, and the spherical cavity is used for placing the feeding device; the beneficial effect of the present invention is: placing the feed in the feeding bucket, by changing the size of the discharge port at the lower end of the spherical cavity The method of structure realizes intermittent and uniform feeding.
