Abstract
The utility model discloses an external rotation type aerator agitator, which comprises a support, wherein the bottom of the support is connected with a shell, and the shell can be rotated around the central axis of the shell. Since the shell of the aerator agitator is designed into the rotatable structure, agitator blades can be connected with the shell during practical assembly, the shell is then driven by a motor to rotate, consequently, the conventional internal rotation type structure is changed, a rotary output shaft of the motor is not directly inserted into water to rotate for agitation any more, but the shell is adopted as a medium to drive the agitator blades to revolve, so that the output speed of the motor is effectively decreased, as a result, the vibration of an aerator is reduced, and the aerating effect is better. The structure of the external rotation type aerator agitator is simple and compact; after the external rotation type aerator agitator is mounted on the aerator, the vibration of the whole machine is little, the rotation speed is reasonable, and the aerating effect is good; and the external rotation type aerator agitator is suitable for use as a fitting for aerators.
Description
Technical field
The utility model relates to aerator agitating device used in a kind of aquaculture.
Background technology
When carrying out aquaculture, the water body of being lived for fishes and shrimps in feeding water etc. provides enough oxygen, needs usually to give in the plant install aerator additional.Aerator is such structure; It has the electromotor that is positioned at the top, and the output torque of electromotor inputs in the agitating device through after a series of deceleration devices; Agitating device has paddle; Reach the water surface or following place stirring, let water fully contact, more oxygen is dissolved in the water with air.Traditional aerator agitating device is a rotatable structure in adopting, particularly; Just be meant that the electromotor output revolving shaft vertically places; Paddle connects after the auxiliary through some, directly connect with said output revolving shaft, and the cover on the top of paddle is covered with shell; Some that are attached to peripheral hardware again are like the cursory levitation device that waits, and this has just accomplished the assembly of aerator.But rotatable structure in this is rotated owing to the output shaft that is motor directly drives paddle, therefore causes the aerator complete machine oscillation big, and rotating speed is too fast, and oxygenation effect is bad.
The utility model content
The purpose of the utility model is for a kind of outward rotation type aerator agitating device that can effectively solve the problem that the aerator vibration is excessive, rotating speed is too fast is provided.
The solution that the utility model solves its technical problem is:
Outward rotation type aerator agitating device, it comprises support, and said support below is connected with shell, and said shell can be along self central axis rotation.
Further improvement as technique scheme is provided with the planetary gear reducing gear in the said shell, said planetary gear reducing gear comprise centre wheel, ring gear and with the planetary gear of centre wheel and ring gear engagement, said ring gear and shell are fixedly connected.
As the further improvement of technique scheme, said support is provided with some cantilever arms.
As the further improvement of technique scheme, said cantilever arm has three, is initial point with the center of support, and the radiation of equidistance circumference is arranged.
The beneficial effect of the utility model is: the utility model is designed to rotatable structure through the shell with the aerator agitating device; When practical set, can paddle be attached on the shell like this; Again by motor-driven shell rotation, this changed traditional in rotatable structure, no longer be that the motor output revolving shaft directly injects and is rotated stirring in the water; Rotate but adopt shell to drive paddle as media; Reduced the electromotor output speed effectively, the vibration of aerator is reduced, oxygenation effect is better.
In addition; The planetary gear reducing gear is housed in the utility model, when the output shaft of the electromotor of peripheral hardware with after centre wheel connects, can drive shell with reasonably speed rotation stably; In limited space, make whole slowing-down structure compact more, the aerator stirring efficiency is provided.
The utility model is simple and compact for structure, installs on the aerator that the back complete machine oscillation is little, rotating speed is reasonable, oxygenation effect good, is applicable to that the accessory as aerator uses.
Description of drawings
Below in conjunction with accompanying drawing and embodiment the utility model is further described.
Fig. 1 is the overall appearance axonometric drawing of the utility model;
Fig. 2 is the three-dimensional cutaway view of the utility model;
Fig. 3 is the upward view of the utility model, and wherein the bottom of shell is in disassembled state.
Embodiment
With reference to Fig. 1～Fig. 3, outward rotation type aerator agitating device, it comprises support 1, and said support 1 below is connected with shell 2, and said shell 2 can be along self central axis rotation.Particularly, on the said support 1 shaft coupling is housed, makes things convenient for the output revolving shaft of electromotor to insert connection.Shell 2 has certain volume; Enlarged rotation stirring scope; Making agitating device no longer is directly to be stretched into the interior rotating manner of rotation stirring in the water by the output revolving shaft of electromotor, but adopts shell to rotate the outer rotating manner that drives the paddle stirring, makes rotation more steady; Rotating speed reduces, and optimizes oxygenation effect.
Further as preferred embodiment; Be provided with the planetary gear reducing gear in the said shell 2; Said planetary gear reducing gear comprise centre wheel 31, ring gear 33 and with the planetary gear 32 of centre wheel 31 and ring gear 33 engagements, said ring gear 33 is fixedly connected with shell 2.The setting of planetary gear reducing gear, the torque output in the middle of can in limited space, will being positioned at is dexterously transferred on the shell 2 that connects with ring gear 33, can also greatly reduce output speed, makes transmission more steady.
Further as preferred embodiment, said support 1 is provided with some cantilever arms 11.
Further as preferred embodiment, said cantilever arm 11 has three, is initial point with the center of support 1, and the radiation of equidistance circumference is arranged.The layout of said cantilever arm 11 is to connect ball float for ease, so just can let aerator swim on the water surface with firm attitude.
More than be that preferred embodiments to the utility model specifies; But the invention is not limited to said embodiment; Those of ordinary skill in the art also can make all equivalent variations or replacement under the prerequisite of the utility model spirit, modification that these are equal to or replacement all are included in the application's claim institute restricted portion.
