Description
Technical Field
The utility model belongs to the biological control field, specifically speaking especially relates to a screening plant of mythimna separata larva.
Background
In the field of biological control, armyworms are often used as food to raise natural enemies, and in order to provide sufficient food for natural enemies, large quantities of artificial breeding of armyworms are required. In the actual artificial breeding process, because the growth speeds of larvae hatched from the same batch of eggs are different, armyworm larvae with different ages and sizes are required to be screened and then are bred respectively, otherwise, the situation that large insects eat small insects can occur, and particularly, if the armyworms to be pupated and the armyworms which are already pupated are not picked out in time, the armyworms can be eaten by other larvae. The current larva screening plant often adopts the screen cloth to screen, because the armyworm larva often attaches to on the screen cloth, leads to screening effect not good.
SUMMERY OF THE UTILITY MODEL
The utility model aims at providing a screening plant of mythimna separata larva to overcome the poor defect of screening plant screening effect of mythimna separata larva among the prior art.
The utility model discloses an adopt following technical scheme to realize:
the screening plant of mythimna separata larva, including screening box and air pump, screening box upper portion is equipped with the mixed larva import that the opening narrowed gradually and is partial to one side from the top down, screening bottom half is equipped with first storage worm groove, second storage worm groove and third storage worm groove from the right side left side in proper order, the air pump is connected the air outlet nozzle, inside the air outlet nozzle intercommunication screening box to locate the below of mixing the larva import.
Preferably, the screening box is provided with a bottom opening, and the first insect storage tank, the second insect storage tank and the third insect storage tank are detachably arranged at the bottom of the screening box through the bottom opening.
Preferably, sandy soil is arranged in the first insect storage tank, the second insect storage tank and the third insect storage tank.
Preferably, the aperture length of the bottom opening of the mixed larva inlet is 20mm-40 mm.
Compared with the prior art, the beneficial effects of the utility model are that:
the utility model discloses according to the different circumstances of mythimna separata size weight, at same speed wind-force, under the blowing of same bore air outlet nozzle level, the power difference of the wind that the mythimna separata receives is not big, and consequently the orbit of mythimna separata whereabouts is different, and heavier mythimna separata falls to the ground the horizontal distance more closely, and lighter mythimna separata falls to the ground the horizontal distance more far away, and the screening efficiency is high, and the screening becomes power height.
Drawings
Fig. 1 is a schematic structural diagram of the present invention;
in the figure: 1. screening the box body; 2. a mixed larva inlet; 3. armyworm larvae; 4. an air pump; 5. an air outlet nozzle; 6. a first insect storage tank; 7. a second insect storage tank; 8. a third insect storage tank; 9. and (4) sandy soil.
Detailed Description
The present invention will be further explained with reference to the accompanying drawings.
As shown in figure 1, mythimna separata larva screening plant, including screening box 1 and air pump 4, screening box 1 upper portion is equipped with the opening from the top down and narrows down gradually and the mixed larva import 2 of bottom opening erroneous tendency one side, screening box 1 bottom is equipped with first storage worm groove 6 from the right side left side in proper order, the second stores up worm groove 7 and third and stores up worm groove 8, air pump 4 connects air outlet 5, inside air outlet 5 intercommunication screening box 1 to locate mixed larva import 2 bottom open-ended below, air outlet 5's bore 10mm-20 mm.
Preferably, be equipped with sand 9 in first storage worm groove 6, second storage worm groove 7 and the third storage worm groove 8, sand 9 plays the cushioning effect, falls when preventing that mythimna separata larva 3 from dropping and hinder.
Preferably, screening box 1 is equipped with the bottom opening, and first storage worm groove 6, second storage worm groove 7 and third storage worm groove 8 pass through the separable establishment in screening box 1 bottom of bottom opening. After the screening is finished, the first pest storage tank 6, the second pest storage tank 7 and the third pest storage tank 8 are directly separated from the screening box body 1, so that the screened pest sticking larvae 3 can be conveniently taken out.
Preferably, the aperture length of the bottom opening of the mixed larva inlet 2 is 20mm-40 mm. The bottom opening allows 1-2 mythimna separata to fall down at every turn, can improve the screening success rate greatly, and through the size of the 2 bottom openings of control mixed larva import, the quantity that 3 fall down from the bottom opening of control mythimna separata larva prevents that a plurality of mythimna separata larva 3 from entangling and leading to the phenomenon of screening failure together.
The utility model discloses a theory of operation: the air pump 4 horizontally outputs airflow with constant flow below the bottom opening of the mixed larva inlet 2 through the air outlet nozzle 5, under the condition of same speed wind power and horizontal blowing through the air outlet nozzle with the same caliber, the acting force of wind borne by the armyworm is not large, by analyzing the falling point of the armyworm larva 3 in different weight ranges at the bottom of the screening box body 1, the positions of the first armyworm storage tank 6, the second armyworm storage tank 7 and the third armyworm storage tank 8 are arranged, the armyworm larvae 3 which are mixed together and have different sizes are put in the mixed larva inlet 2, the armyworm larva 3 falls through the bottom opening of the mixed larva inlet 2, the air blown out of the air outlet nozzle 5 blows the armyworm larva 3 to the left side, as shown in figure 1, the falling track of the large-weight armyworm larva 3 is track 1, the falling track of the medium-weight armyworm larva 3 is track 2, the falling track of the small-weight armyworm 3 is track 3, And after the screening is finished, the first pest storage tank 6, the second pest storage tank 7 and the third pest storage tank 8 are taken out to be collected, namely the medium-weight armyworm larvae 3 and the small-weight armyworm larvae 3 fall into the first pest storage tank 6, the second pest storage tank 7 and the third pest storage tank 8 respectively.
