Description
Technical field
The utility model relates to a kind of Fish hatcheries auxiliary equipment, particularly a kind of spot mandarin fish egg hatching equipment.
Background technology
Along with rising steadily of Ban Mandarin export price, and it is seriously exhausted to fish for the natural resources caused in a large number, and the artificial propagation carrying out Ban Mandarin is imperative.The artificial propagation of current Ban Mandarin mainly adopts miniflow water or net cage Lentic hatching, although these methods are feasible, still there are problems: as each hatching amount is little, and incubation rate is not high yet; Miniflow water or Lentic hatching, all easily cause the ischaemia in hatching process, thus reduce incubation rate.Therefore now a kind of Xin Xing Ban Mandarin hatch fish roe equipment that can solve the problem is needed.
Summary of the invention
The utility model is the above-mentioned deficiency in order to solve existing for prior art, proposes a kind of structure simple, designs ingenious, economical and efficient, and effectively can improve the spot mandarin fish egg hatching equipment of spot mandarin fish egg hatching amount and incubation rate.
Technical solution of the present utility model is: a kind of spot mandarin fish egg hatching equipment, comprise support 1, it is characterized in that: the housing 2 being supported with back taper on support 1, the bottom of housing 2 is provided with the water inlet 4 with valve 3, the middle part of housing 2 is provided with bolting silk filter 5, the top of housing 2 is connected with annual disk 6, the excircle of annual disk 6 is provided with overflow ring flat-plate 7, bolting silk back-up ring 8 is also provided with at the opening part at housing 2 top, and the top of bolting silk back-up ring 8 is higher than the upper edge of overflow ring flat-plate 7, and the ratio between the diameter D of the housing 2 of back taper and high H is 3:4.
Described bolting silk filter 5 and the order number of bolting silk back-up ring 8 are 120 orders.
Compared with the existing technology, tool has the following advantages the utility model:
The spot mandarin fish egg hatching equipment of this kind of version, have the following advantages compared to traditional incubation equipment: the mode creatively adopting bottom water inlet, the bolting silk filter being simultaneously positioned at housing central section can allow spot mandarin fish ovum away from strong current near water inlet, bolting silk filter can effective dispersing water flow, current are avoided directly to impact fish-egg, so just can realize Lotic hatching, improve hatching amount; Bolting silk net can also filter the zooplankton and impurity that do not have to remove completely further simultaneously, and then improves the incubation rate of spot fish-egg.And its manufacture craft is simple, and cheap for manufacturing cost, therefore can say that it has possessed multiple advantage, be particularly suitable for applying in the art, its market prospects are very wide.
Accompanying drawing explanation
Fig. 1 is the structural representation of the utility model embodiment.
Embodiment
Below in conjunction with accompanying drawing, embodiment of the present utility model is described.As shown in Figure 1: a kind of spot mandarin fish egg hatching equipment, comprise support 1, support 1 is supported with the housing 2 in back taper, the bottom of housing 2 is provided with water inlet 4, water inlet 4 is provided with valve 3, the middle part of housing 2 is provided with bolting silk filter 5, the order number of this bolting silk filter 5 is preferably 120 orders, an annual disk 6 is then connected with at the top of housing 2, the excircle of this annual disk 6 is provided with the overflow ring flat-plate 7 with certain altitude, bolting silk back-up ring 8 is also provided with at the opening part at housing 2 top, and the order number of this bolting silk back-up ring 8 is also preferably 120 orders, the top of bolting silk back-up ring 8 is higher than the upper edge of overflow ring flat-plate 7, ratio simultaneously between the diameter D of the housing 2 of back taper and high H is 3:4.
The course of work of the spot mandarin fish egg hatching equipment of the utility model embodiment is as follows: the inner chamber from the opening part of housing 2 upper end, spot mandarin fish ovum being put into housing 2 when being full of breeding water body within the case 1, Open valve 3 in hatching process, current are allowed to enter in housing 2 by water inlet 4, along with being on the increase of water body in housing 2, water body can by the opening on housing 2 top, overflow from the top of overflow ring flat-plate 7 through after bolting silk back-up ring 8, the water body this ensures that thered in housing 2 is flowing all the time, the top of the bolting silk back-up ring 8 at housing 2 top is again higher than the upper edge of overflow ring flat-plate 7 simultaneously, therefore the spot mandarin fish ovum in housing 2 can not along with water sports be to annual disk 6 place, ensure carrying out smoothly of hatching.
Claims (2)
1. a spot mandarin fish egg hatching equipment, comprise support (1), it is characterized in that: the housing (2) being supported with back taper on support (1), the bottom of housing (2) is provided with the water inlet (4) with valve (3), the middle part of housing (2) is provided with bolting silk filter (5), the top of housing (2) is connected with annual disk (6), the excircle of annual disk (6) is provided with overflow ring flat-plate (7), bolting silk back-up ring (8) is also provided with at the opening part at housing (2) top, and the top of bolting silk back-up ring (8) is higher than the upper edge of overflow ring flat-plate (7), and the ratio between the diameter D of the housing of back taper (2) and high H is 3:4.
