Environmentally-friendly feeding device for aquaculture

Abstract

The invention discloses an environmentally-friendly feeding device for aquaculture, belonging to the technical field of aquaculture. The environmentally-friendly feeding device comprises a fixed box,a water pumping pipe, a collection mechanism and a lift-drop mechanism. According to the invention, a feed is stored through a feed chamber, and when feeding is needed, control valves and feeding pipes are opened for feeding, so feeding is simple, convenient, time-saving and labor-saving; a motor is started to enable the lift-drop mechanism to drive a moving sleeve to move upward, and connecting rods enable rotating rods to rotate to enable the connecting rods to open collection nets, so a residual feed remained after completion of feeding falls onto the collection nets and finally falls intothe collection drum, and larger collection range and convenient and effective collection are realized through the collection nets; and the residual feed located at the bottom part of the water pumpingpipe together with pond water are pumped out through a water pump and discharged into a collection groove, so the pond water passes through a first filter screen and returns to a culture pond, whilethe residual feed remains in the collection groove.

Description

technical field [0001] The invention relates to the technical field of aquaculture, in particular to an environment-friendly feeding equipment for aquaculture. Background technique [0002] Aquaculture is the production activity of breeding, cultivating and harvesting aquatic animals and plants under human control. It generally includes the whole process of growing aquatic products from seedlings under artificial breeding management. In a broad sense, it can also include the proliferation of aquatic resources. [0003] Aquaculture includes extensive culture, intensive culture and high-density intensive culture. Extensive culture is to put seedlings in small and medium-sized natural waters, and to grow aquatic products completely by natural bait, such as fish culture in lakes and reservoirs and shellfish culture in shallow seas. Intensive farming is the use of bait and fertilization methods to grow aquatic products in smaller water bodies, such as pond fish farming, cage f...

Problems solved by technology

As a result, various toxic and harmful substances in the breeding water body exceed the standard, and the breeding objects live in a bad or even life-threatening harsh environment for a long time

In addition, the aquaculture feed accumulates and dissolves in the water, resulting in eutrophication of the water body, which will also affect the aquaculture objects

[0005] It is a relatively common intensive farming method to raise fish in ponds. When fish are raised in ponds, it is necessary to add feed regularly and quantitatively. The existing feed feeding methods mainly include manual feeding and machine feeding. When feeding manually, it is usually human Farmers move in small boats in the pond. When they move to the feed delivery point, they put the feed carried on the boat into the water. This delivery method is time-consuming and laborious, and the delivery efficiency is low. The feeding device and the fixed feeding device, wherein the mobile feeding device is equipped with a floating platform, a feeding mechanism and an advancing mechanism, and the feeding device is moved in the pond through the advancing mechanism, and then the feed is fixed at a fixed point; while the fixed feeding device usually includes a Fixed bracket, the feeding device is fixed on the bracket, when feeding is required, only need to open the feed box in the feeding mechanism

[0006] The existing penetrating feed feeding devices all realize the simple function of feeding feed, but do not have the function of feed recovery, and in the process of feed feeding, the amount of feed feeding is relatively large, because the farmed fish cannot completely eat all the feed or feed Some feeds will fall directly to the bottom of the water without being eaten when put in. These feeds will accumulate and dissolve in the water, which will have adverse effects on the water body, thereby reducing the health and quality of farmed fish.
