Problems solved by technology

At the same time, the control of the feeding amount in the process of feeding the feed also has a greater impact on the output of crayfish: if the feeding amount is too small, the problems of slow growth and cannibalism of crayfish will easily occur; if the feeding amount is too much, Not only is the feed wasted, but the excess feed will easily cause the water quality to deteriorate in a short period of time, causing the crayfish to be infested by unnecessary pests and diseases and hypoxia

Embodiment 1

[0037] Such as figure 1 As shown, the paddy field aquaculture feeding device includes a strip-shaped net bag 1, and the strip net bag 1 is woven by a flexible rope;

[0038] It also includes a stand for erecting the strip net bag 1, the stand includes a pole 7, and a support plate 8 is also fixed on the pole 7, and the support plate 8 protrudes relative to the side of the pole 7;

[0039] The strip-shaped net bag 1 is also provided with a feeding net mouth 2 .

[0040] In the prior art, a feeding device such as the one provided by the patent application No. 201620027349.9 has appeared for crayfish breeding feed throwing. The above device solves the problem of recycling the residual food when there is food residue to save feeding input and pollute the water body , but the structural form and working principle of the above device make the feeding platform on it inconvenient to be set as a slender platform, so it is not suitable for the breeding ditch that is set for the paddy f...

Embodiment 2

[0055] Such as figure 1 As shown, the present embodiment is further limited on the basis of Embodiment 1: the feeding net mouth 2 is multiple, and the feeding net mouth 2 is arranged at intervals along the length direction of the bar-shaped net bag 1, and each feeding net mouth 2 is connected to the strip net bag. The middle area of ​​shaped net bag 1 communicates;

[0056] The connecting line of a plurality of feeding net mouths 2 is a straight line, and the straight line is parallel to the length direction of the strip net bag 1 . In this scheme, since the feeding net mouth 2 is a plurality along the lengthwise direction of the strip net bag 1, the feeding net can be thrown from one end of the feeding net to the other end while pulling the feeding net. Feed is dropped into through feeding net mouth 2 on the one hand, like this, can make feed can be evenly distributed in the strip net bag 1, by increasing the mode of feeding area as far as possible, facilitate crayfish to fe...

Embodiment 3

[0064] This embodiment is further defined on the basis of any one of the technical solutions provided by any one of the above embodiments: as a low-cost and long-life rope solution, the rope is a fishing net line.

[0065] In order to make the strip-shaped net bag 1 thrown in the breeding ditch, the upper part of which collapses downward can affect the feeding area of ​​crayfish as little as possible. After the strip-shaped net bag 1 is opened, its cross section is elliptical.

Abstract

The invention discloses a paddy field aquaculture feeding device, which comprises a strip-shaped net bag, the strip-shaped net bag is braided by flexible ropes; and a stand for erecting the strip-shaped net bag, the stand It includes a vertical pole on which a support plate is fixed, and the support plate protrudes outward relative to the side of the vertical pole; the strip-shaped net bag is also provided with a feeding net opening. The feeding device is convenient for fixed-point feeding to the breeding area, and at the same time, it is convenient for fixing.

Description

technical field [0001] The invention relates to the technical field of crayfish breeding appliances, in particular to a paddy field aquaculture feeding device. Background technique [0002] There are a large number of rice fields distributed in the middle and low mountainous and hilly areas of my country, and these rice fields generally have sufficient water sources, good water quality, and convenient drainage and irrigation. At the same time, these waters are rich in organic matter, and the size of a single paddy field is suitable. In the prior art, farmers adapt measures to local conditions, and crayfish cultivation in paddy fields has become a very important means of crayfish cultivation. [0003] In order to realize the high yield of crayfish paddy farming, feeding feed is an extremely important task in crayfish farming. At the same time, the control of the feeding amount in the process of feeding the feed also has a greater impact on the output of crayfish: if the feed...
