[0027] This embodiment provides a collection device for shrimp ponds, such as Figure 1-3 As shown, the collecting device is set in shrimp pond A for use.

[0028] The collecting device comprises a lifting device 1, a cover body 2, a feces pipe 3, a shrimp shell pipe 4 and a filtering device 5; the input end of the feces pipe 3 is connected to the bottom A1 of the shrimp pond, and a filter screen (not shown in the figure) is provided at the input end of the feces pipe 3; the cover body 2 is provided at the bottom A1 of the shrimp pond and covers the input end of the feces pipe 3, and a discharge channel 6 is formed between the cover body 2 and the bottom A1 of the shrimp pond; the shrimp shell pipe 4 is passed through the cover body 2, the input end of the shrimp shell pipe 4 is communicated with the discharge channel 6, and the output end of the shrimp shell pipe 4 is connected to the filtering device 5; the lifting device 1 is connected to the cover body 2, and is used to close and open the discharge channel 6, and to adjust the size of the discharge channel 6.

[0029] The cover body 2 is placed on the bottom A1 of the shrimp pond. When the cover body 2 contacts the bottom A1 of the shrimp pond, the discharge channel 6 is closed; when the cover body 2 separates from the bottom A1 of the shrimp pond, the discharge channel 6 is opened; the position of the cover body 2 is changed by the lifting device 1, so as to adjust the size of the discharge channel 6 to adapt to the discharge of shrimp shells at different growth stages. At the same time, the feces pipe 3 is connected to the bottom A1 of the shrimp pond, and a filter is provided on the feces pipe 3 to filter shrimp shells, so that shrimp feces are discharged through the feces pipe 3 and shrimp shells are discharged through the shrimp shell pipe 4; because the feces pipe 3 and the shrimp shell pipe 4 are both connected to the discharge channel 6, when the discharge channel 6 is opened, shrimp feces and shrimp shells can be discharged at the same time, and the discharge efficiency is high.

[0030] The filtering device 5 is connected to a circulation pipeline 7, and the circulation pipeline 7 outputs the liquid in the filtering device 5; in this embodiment, the circulation pipeline 7 is connected to a microfilter (not shown in the figure).

[0031] The shrimp shell pipe 4 is arranged above the feces pipe 3, the input end of the shrimp shell pipe 4 is arranged opposite to the input end of the feces pipe 3, the level of the top of the filter device 5 is higher than the liquid level A2 in the shrimp pond A, and the level of the output end of the shrimp shell pipe 4 and the level of the bottom of the filter device 5 are lower than the liquid level A2 in the shrimp pond A. In a preferred embodiment, the level of the top of the filter device 5 is 20 cm higher than the liquid level, and the level of the bottom of the filter device 5 is 20 cm lower than the liquid level.

[0032] The input ends of the shrimp shell pipe 4 and the feces pipe 3 are corresponding and relatively arranged. The distance between the shrimp shell pipe 4 and the feces pipe 3 is short, and the shrimp shells isolated by the filter can be quickly discharged through the shrimp shell pipe 4; at the same time, since the horizontal height of the output end of the shrimp shell pipe 4 is lower than the liquid level height in the shrimp pond A, the shrimp shells can be discharged outward through the shrimp shell pipe 4 under the action of negative pressure.

There are three fixed columns 11, three connecting columns 12 and three lifting drives 14 respectively; one fixed column 11 cooperates with one connecting column 12 and one lifting drive 14. This provides good stability.

[0036] One end of the fixed column 11 passes through the cover 2 and is fixed to the bottom A1 of the shrimp pond, the other end of the fixed column 11 is connected to the lifting bracket 13, the lifting drive 14 is installed on the lifting bracket 13, the connecting column 12 is sleeved outside the fixed column 11, one end of the connecting column 12 is connected to the cover 2, and the other end of the connecting column 12 is connected to the movable end of the lifting drive 14. The fixed column 11 guides the connecting column 12 while supporting the lifting device 1, so that the connecting column 12 moves along the length direction of the fixed column 11, so that the position of the cover 2 can be stably adjusted, and the reliability is good.

[0037] A resisting portion 21 is provided at the bottom end of the cover body 2 to increase the contact area between the cover body 2 and the bottom A1 of the shrimp pond. The resisting portion 21 is arranged in parallel with the bottom A1 of the shrimp pond to improve the fit between the resisting portion 21 and the bottom A1 of the shrimp pond. The resisting portion 21 is provided to improve the blocking effect of shrimps and shrimp feces when the discharge channel 6 is closed. An opening 22 connected to the feces pipe 3 is provided on the resisting portion 21; guide holes 23 cooperating with the fixed column 11 are provided on the cover body 2 and the resisting portion 21.

When the discharge channel 6 is opened, the shrimp feces flows to the feces pipe 6, and the shrimp shells enter the cover body 2 through the opening 21 and flow to the shrimp shell pipe 4.

[0038] The working principle of the utility model is as follows: before putting in the shrimp fry, the lifting device 1 drives the cover body 2 to move downward, so that the cover body 2 contacts the bottom A1 of the shrimp pond and closes the discharge channel 6; then the liquid and shrimp fry are injected into the shrimp pond A; since the newly cultured shrimp fry are relatively small, this can prevent the shrimp fry from flowing out of the shrimp pond A; after the shrimp fry enters the next growth stage, the lifting device 1 drives the cover body 2 to move upward, so that the cover body 2 is separated from the bottom A1 of the shrimp pond and the discharge channel 6 is opened; the shrimp shells and shrimp feces enter the inside of the cover body 2 through the discharge channel 6, the shrimp feces are discharged outwardly through the feces pipe 3, and the shrimp shells are discharged outwardly through the shrimp shell pipe 4; after the shrimp fry enters the next growth stage again, the volume of the newly shed shrimp shells increases, and at this time the cover body 2 is moved upward again to increase the height of the discharge channel 6, so that the newly shed shrimp shells can be discharged outwardly through the discharge channel 6. The utility model can adjust the size of the discharge channel 6 according to the volume of live shrimps at different growth stages, so that the detached shrimp shells can be discharged through the discharge channel, while the live shrimps are blocked, and the shrimp shells and shrimp feces in the shrimp pond A are effectively discharged.
