Further, the upper portion coaxial coupling of pivot has the carousel, is equipped with the discharge opening on the eccentric position of carousel, and the upper portion of box is equipped with the storage case, and the lower part of storage case is equipped with the bin outlet that can coincide with the discharge opening, and the lower part of storage case pastes with the upper portion of carousel and leans on. Through the setting, when the carousel rotated along with the pivot, the discharge opening can with the relief hole coincidence, discharge opening and relief hole intermittent type nature coincidence can carry out intermittent type nature to put into the foodstuff in the box, avoid once only putting into too much the foodstuff and cause the waste.
Furthermore, the lower part of the box body is provided with universal wheels, and the universal wheels are provided with buckles for locking the universal wheels. Through the arrangement, the device is convenient to move.
Drawings
FIG. 1 is a schematic structural diagram of an embodiment of a screening device for tilapia culture according to the present invention;
fig. 2 is a top view of the baffle of fig. 1.
Detailed Description
The following is further detailed by way of specific embodiments:
reference numerals in the drawings of the specification include: the device comprises a box body 1, a motor 2, universal wheels 3, a baffle plate 4, a rotating shaft 5, blades 6, a filter screen 7, spiral blades 8, a sleeve 9, a water outlet 10, a placing frame 11, a rotary table 12, a discharge hole 13 and a storage box 14.
Referring to fig. 1 and 2, a screening device for tilapia culture comprises a box body 1 and a driving part, wherein the driving part is a motor 2 in the embodiment; universal wheel 3 is installed to box 1 lower part, installs the buckle that is used for locking universal wheel 3 on the universal wheel 3.
