Example Embodiment

[0013] Example 1:
[0014] Such as figure 1 As shown, the mud loach pump device with adjustable water suction includes a ceramic tube 7, a jet 6 connected to the ceramic tube 7, a suction pump 10 connected below the jet 6, and a suction pipe 8 on the side of the suction pump 10 , The suction pipe 8 is connected with the suction branch 9 placed below the water surface, the suction pipe 9 has a sediment separation net at its water inlet, and the ceramic pipe 7’s water inlet is connected with the suction pipe 1 placed below the water surface. The loach is extracted above the loach breeding pond. When the loach does not hide in the mud bottom, the loach can be extracted effectively and quickly, with little damage to the loach. The pump 10 is used to directly extract the water discharge box in the breeding pond. The direction of the water outlet 6 , The negative pressure in the ceramic tube 7 is formed, and the suction tube 1 is used to start the extraction of the loach, which effectively improves the efficiency of the jet extraction of the loach.

Example Embodiment

[0015] Example 2:
[0016] This embodiment is further optimized on the basis of Implementation 1: Figure 1-3 As shown, a filter box 3 is provided between the jet 6 and the water inlet of the ceramic tube 7. The filter box 3 is vertically connected to the wall below the ceramic tube 7, and the bottom of the filter box 3 is connected with the suction pipe 8, and the bottom of the filter box 3 is provided The inclined filter plate 4, above the filter plate 4, is provided with a filter tube 2 vertically connected to the tube wall below the ceramic tube 7, and a filter screen 201 is provided at the connection between the filter tube 2 and the ceramic tube 7. The filter tube 2 is made of elastic material. 2 Electromagnets 202 are provided on the outer arms on both sides. The bottom of the filter plate 4 and the filter box 3 form a sediment collection chamber 5. In the initial stage of sucking loach, the negative pressure in the ceramic tube 7 is maintained by the control electromagnet 202 to squeeze the filter tube 2 The filter tube 2 is closed. When the extraction process is normal, the electromagnet 202 is disconnected from the electricity, and the water flowing through the ceramic tube 7 is filtered by the filter screen 201. The sediment has a certain gravity, and a part of the sediment reaches the filter through the filter screen 201. The bottom of the pipe 2 is filtered by the filter plate 4 to be collected and then waited for centralized treatment in the sediment collection chamber 5. The above design effectively separates the loach from the sediment in the extracted water body, speeds up the efficiency of loach extraction, reduces subsequent cleaning work, and avoids The inside of the device is blocked. Since the filter box 3 is connected to the suction pipe 8, the suction force of the suction pump 10 can be applied to the filter pipe 2 to improve the effect of sediment separation and increase the flow of water drawn by the suction pump 10 to increase the ceramic The negative pressure in the pipe 7 increases the speed of the loach extraction, and realizes the faster the extraction efficiency of the loach and the separation effect of the loach and the sediment under the same energy consumption. The water inlet of the suction pipe 1 surrounds the cone-shaped funnel 102, which is beneficial to expand the loach extraction range, increase the number of loach extraction, and can also disperse the extracted suction to prevent the suction from absorbing too much sediment. The inner wall of the water inlet of the suction pipe 1 is provided with a symmetrical spherical restrictor 101. The restrictor 101 is hollow inside and has a circular hole on the surface. The diameter of the circular hole is preferably 0.3cm. The restrictor 101 is used to filter the sucked sediment to The inside of the flow limiting block 101 facilitates the subsequent sediment separation effect of the filter tube 2 and can also restrict large objects from entering the suction tube 1 to damage the device when the loach is extracted.
