Description

Water-wheel blade

The utility model relates to pump-unit, and finger is the improvement to a kind of Water-wheel blade especially.

Waterwheel is common by everybody, it usually is used as the irrigation in farmland, reach the instrument that Xiang Shuizhong injects oxygen and (existing Water-wheel blade structure is understood to stir the water source when breed fish in the instrument of draining and fish pond in order to make the auditor, see also Fig. 1), the structure of existing Water-wheel blade is: it mainly comprises a wind blade main body 1 and a blade rack 2, wind blade main body is that a plane and inclined-plane are the  type, its each corner all is tip shape, dig on the wind blade main body plane 3 and be provided with plurality of holes 4, hole system vertically hollows out, the bottom surface is welded and is established a blade rack 2 in the middle of the wind blade main body, (please consulting Fig. 2 again), after Water-wheel blade was assembled in the waterwheel support body, middle circle axle 17 centers of support body were provided with a circular hole 18 and can be articulated with transmission shaft.There is following shortcoming in use in this kind Water-wheel blade: (1) because each corner of wind blade main body all is tip shape, and when its rotation strikes waters, when patting fish, fish is subject to be sharp-pointed corner incised wound, and suffered resistance is bigger; (2) after its long service time, its wind blade main body be the place, inclined-plane because no any subsidy competent structure very easily is out of shape impaired because of striking waters for a long time; (3) owing to hole system on the wind blade main body plane vertically hollows out on earth, when its rotation, directly by hole, the bubble that can produce is less for current, and it is less to inject oxygen in water; (4) because the horizontal plane of wind blade main body system is complete plane, when blade rack and blade body welding, because it is little with the wind blade main body area of contact that is the plane to be the blade rack of round bar shape, the welding surface of contact is little, easily comes off in the use.(5) because the set circular hole in support body circle core shaft center be circular, transmission shaft also be circular and with the circular hole interlocking, when turning round for a long time, after fastening screw gets loose, can produce the phenomenon of idle running.

The purpose of this utility model is to overcome the shortcoming that above-mentioned Water-wheel blade exists, and provides a kind of and can not hinder when waterwheel rotates that fish, resistance are little, blade can distortion, the Water-wheel blade of blade and support firm welding.

To achieve these goals, the utility model adopts following technological scheme: the same with common Water-wheel blade, this Water-wheel blade comprises a wind blade main body and blade rack, wind blade main body is that a plane and inclined-plane are the  type, blade rack is established in the weldering of wind blade main body bottom surface, different is to convex with the circular arc raised line on this wind blade main body plane and the inclined-plane, the corresponding bottom surface of wind blade main body and raised line is toward being recessed the formation arc groove, the left and right side, plane of wind blade main body and the side on inclined-plane thereof all are circular arc type backrush limit, between the circular arc raised line of wind blade main body, be provided with long strip hole or roundlet hole, this rectangular hole or roundlet hole are a vertical hole after being and being arranged with an inclined-plane toward the inboard earlier again, blade rack is put along the arc groove of wind blade main body bottom surface indent, and weld the whole cambered surface that makes blade rack and the arc groove of the wind blade main body bottom surface back of fitting fully.

Because the utility model adopted the left and right side of wind blade main body and the side at place, inclined-plane all to be circular arc type backrush limit, make fan blade when rotating, resistance is little, can not injure fish; The plane of while wind blade main body and inclined-plane are provided with the circular arc type raised line and blade support makes this fan blade firmly and not yielding along welding in the circular arc type groove of wind blade main body bottom surface; And, make to produce more steam bubble when fan blade rotates and can in water, inject more oxygen in water owing on the plane of wind blade main body, dig long strip hole or the small circular hole that is provided with the band inclined-plane.

Below in conjunction with accompanying drawing the utility model is done further detailed explanation.
