[0001] The utility model relates to the technical field of aquaculture, and in particular to a device for ecologically culturing freshwater shrimps in a pond. Background Art

[0002] Green shrimp is an arthropod of the genus Macrobrachium, family Macrobrachium, order Decapoda. It has a short and thick body, and the whole body consists of the cephalothorax and abdomen. The cephalothorax is thick, the front part of the abdomen is thicker, and the back part gradually becomes thinner and narrower. There is a hard shell on the body surface, which plays a role in protecting the body. It is named after its blue-green body color. Green shrimp is warm in nature and sweet in taste. It has the effects of tonifying the kidney and strengthening yang, promoting lactation, removing blood stasis and detoxifying. It can treat kidney deficiency, impotence, lack of milk, erysipelas, carbuncle, ecthyma, etc.

[0003] In the prior art, the equipment for ecological pond shrimp farming mainly includes oxygenation equipment, water quality monitoring and regulation equipment, feed feeding equipment and disease prevention and control facilities, among which the feed feeding equipment is used to feed the shrimp; however, the common feeding equipment has a low degree of automation and cannot accurately determine the time and amount of feed for a single feeding. If too much feed is put in, sedimentation will occur, resulting in an increase in nitrogen content in the water body, causing excessive ammonia nitrogen and affecting water quality. How to invent a device for ecological pond shrimp farming to improve these problems has become an urgent problem to be solved by those skilled in the art. Utility Model Content

[0004] In order to make up for the above shortcomings, the utility model provides a device for ecologically culturing freshwater shrimps in a pond, aiming to improve the problem that common feeding equipment has a low degree of automation and cannot accurately determine the time and amount of feed for a single feeding.

[0005] The utility model is achieved in this way:

[0006] The utility model provides a device for ecologically culturing freshwater shrimps in a pond, comprising a fixed platform, a material box and a discharge pipe arranged on the fixed platform, wherein a plurality of fixed legs are fixedly connected to the lower end of the fixed platform, four support rods are fixedly connected to the upper outer wall of the fixed platform, one end of the support rod is fixedly connected to the material box, a discharge pipe is installed on the lower inner wall of the material box, a solenoid valve is installed on the discharge pipe, one end of the discharge pipe is connected to a discharge hopper, a fixed plate is fixedly connected to one side of the discharge hopper, a motor is installed on the upper outer wall of the fixed plate, and a driving gear is installed below the fixed plate;

[0007] The upper outer wall of the discharge pipe is rotatably connected to the inner wall of the lower hopper, a plurality of discharge ports are provided on the lower outer surface of the discharge pipe, a collection frame is fixedly connected to the outer wall of the discharge pipe near the discharge ports, and a plurality of sieve holes are provided on one side of the collection frame.

[0008] Preferably, the fixing legs are fixed to the bottom of the pond, and the fixing plate is at a height above the horizontal plane.

[0009] Preferably, an infrared ranging sensor penetrating the upper outer wall is installed on the upper outer wall of the lower hopper, and the output end of the motor is fixedly connected to one end of the driving gear.

[0010] Preferably, one end of the driving gear is rotatably connected to the inner wall of the fixed plate, and the outer wall of the discharge pipe is fixedly connected to an active gear ring meshing with the driving gear.

[0011] By adopting the above technical solution, the start time of the solenoid valve is remotely controlled. When the shrimps need to be fed, the feed is put into the feed hopper through the feed pipe and the height of the feed is monitored by the infrared ranging sensor. When the feed reaches the appropriate height, the feed is stopped. At this time, the motor is started to rotate the discharge pipe at the lower end, and the feed is thrown out through the aggregate frame under the action of centrifugal force and falls into the water outside.

[0012] Preferably, a rotating shaft rotatably connected to the inner wall of the fixed platform is fixedly connected to the bottom end of the aggregate frame, and a plurality of crushing rollers are rotatably connected to the interior of the aggregate frame.

[0014] By adopting the above technical solution, during the process of throwing out the feed, the crushing roller rotates at the same time, crushing the larger particles and agglomerated feed inside the aggregate frame so that they can smoothly pass through the sieve holes and fall into the water.

[0015] The beneficial effects of the utility model are:

[0016] The time and interval for the solenoid valve to start are set in advance through the program. When the time point is reached, the solenoid valve starts to allow the feed in the feed box to be deposited into the bottom of the lower hopper and the discharge pipe for accumulation. When the feed height inside the lower hopper reaches the set value, the feed input is stopped, the motor starts to rotate the discharge pipe, and the crushing roller rotates at the same time to crush the larger feed between the rollers. Finally, the feed is thrown through the sieve holes under the action of centrifugal force into the surrounding water surface to feed the shrimps, thereby increasing the feeding range. At the same time, a fixed time point and feed quantity are set to improve the accuracy of each feeding, and to avoid excessive feeding causing waste of feed and sinking to the bottom, affecting water quality.
