Problems solved by technology

[0003] When the current waterwheel type aerator is in use, the blades are generally immersed in the water surface for vertical rotation, so that the dissolved oxygen and oxygen exchange characteristics are formed in the water body. The water liquid is not easy to replace, and with the diversion effect of the impeller, there will be backflow, which may dissolve oxygen in the water liquid in the same area, so that the diffusion efficiency of oxygen and water liquid will be very slow, reducing the oxygen exchange on the water surface Comprehensiveness, reducing the work effect of oxygen exchange and dissolved oxygen; the waterwheel aerator is generally connected with the aerator by a pull rope, and the operator uses the pull rope to move the aerator, but the aerator is on the water surface There will be a large bonding force and the obstruction formed by the water when the waterwheel moves, which will cause the staff to pull the pull rope with great effort, making it very difficult to move the position of the device and increase the limitations of the use of the device. Reduce the practical value of the device; when the impeller rotates in contact with the water, it is easy to adhere to the aquatic plants and Microcystis in the water, and with the stirring force, it will wrap the impeller surface with the impurities in the water, which not only affects The normal operation of the impeller and the drive shaft also greatly hinders the subsequent cleaning work, increasing the difficulty and inconvenience of the operator's work

Embodiment 1

[0031] Example 1, such as Figure 1-5 As shown, during the period when the impeller 13 drives the blade 12, it will automatically brush through the position of the cleaning brush 5, so as to prevent the aquatic weed impurities adhered to the blade 12 from flowing into the transmission gap between the impeller 13 and the transmission shaft 6 to be entangled, increasing the device's Self-cleaning function enhances the convenience of follow-up cleaning work.

Embodiment 2

[0032] Example 2, such as Figure 6-7As shown, when the device needs to be moved, the high-pressure air flow can be introduced into the sealing groove 114 by starting the high-pressure blower 11. At this time, the gas will flow into the four groups of injection pipes 113 under the guidance of the hemispherical air guide block 112, and With the helical cooperation of the helical pattern 115 to strengthen the output force after the gas injection, four groups of injection gas can be used to promote the device to have a thrust, which can slowly move on the water surface, so as to adjust the installation position of the device, and at the same time, the operator The pull rope connected with the device can be pulled to perform secondary output, which facilitates the movement of the control device and increases the convenience and practicality of the device.

[0033] Working principle: when the device is in use, first put the device into the breeding water surface, then start the ser...

Abstract

The invention discloses an aerator for crayfish farming. The aerator comprises a mounting groove and a controller, a floating plate is arranged at the bottom of the mounting groove, the two sides of the inner side of the floating plate are sleeved with gas-liquid turbulence assemblies, floating boats connected with each other are arranged at the tops of the two sides of the mounting groove, a mounting bin is arranged at the top of the mounting groove, double-shaft motors are arranged on the two sides of the bottom in the mounting bin, and transmission shafts are arranged at the output ends ofthe double-shaft motors. Through mutual cooperation of the gas-liquid turbulence assemblies, auxiliary oxygenation work can be formed, meanwhile, water liquid below the aerator is promoted to be turbulent, the flow direction of the water liquid is diffused and made to be consistent with the rotating flow direction of an impeller and blades, the phenomenon that dissolved oxygen water liquid flows back is prevented, an arc-shaped guide sleeve, an arc-shaped damping column and a buffer spring are connected and matched, so that the floating buffering and damping capacity of the floating plate is improved, and the operation stability of the aerator and the comprehensiveness of water and oxygen dissolution are improved.

Description

technical field [0001] The invention relates to the technical field of aeration machines, in particular to an aeration machine for crayfish breeding. Background technique [0002] The aerator has the functions of increasing oxygen, stirring water and aerating. When raising crayfish in ponds, high-yield ponds need to use an aerator. It can be said that the aerator is currently the most effective way to improve water quality, prevent floating heads, and increase production. One of the special farming machinery; [0003] When the current waterwheel type aerator is in use, the blades are generally immersed in the water surface for vertical rotation, so that the dissolved oxygen and oxygen exchange characteristics are formed in the water body. The water liquid is not easy to replace, and with the diversion effect of the impeller, there will be backflow, which may dissolve oxygen in the water liquid in the same area, so that the diffusion efficiency of oxygen and water liquid wil...
