Description

The invention relates to the protection of plants from insect pests biological method, namely, devices for artificial breeding of insects. $

The purpose of the invention is to improve the performance and quality of the biomaterial.

FIG. 1 is a diagram of an installation for laying and collecting eggs; insects, worn, front view} in FIG. 2 - the same, side view.

The installation contains a chamber 1 for laying eggs with rectangular cages 2 arranged in it in parallel in the form of rectangular boxes, discharge windows 3 located in opposite walls of cages 2, flaps 4, insect pipe 5, feeding the pallet 6 for collecting eggs, drive 7 cages 2, 20

frame 8, on which mesh cages 2 are mounted, pendants 9, fitted with grooves 10 and 11, distribution, telescopic mechanism 12 with shutter 13. 25

Suspension 9 is connected to the drive 7 cages 2. Under the chute 10 of the pallet 6 is suction air duct 14, connected to the separator 15 and then with a capacity of 16 for collecting eggs.

'For the circulation of the air flow in the chamber 1 and cleaning the mesh cages 2, the discharge duct 17 is connected to them through the air conditioner 18 and the suction duct 19, which is connected to the fan 20 through the valve 21 and the air duct 22 is connected to the distributors for blowing eggs out of the common sump from the injection line 23 according to the number of mesh cages 2. For the convenience of servicing the latter, chamber I is closed by a double cover 24 and inside the chamber 1 under the cover 24 there is a block of 25 temperature sensors and in the best position, as well as a lamp 26.

All installation mechanisms operate in an automatic mode, corresponding to the duration of insect egg-laying, set by the operator-50 torus on the console 27.

The drive 7 includes an electric motor 28 with an eccentric 29, which allows changing the amplitude of oscillations of the set-55 cages 2, which ensures their swinging movement. Mesh cages installed in the chamber 1 with the possibility of tilting in the direction of the discharge window 3.

Installation for laying and collecting insect eggs works as follows.

Butterflies grain moth periodically several times a day through insect 5 by air are fed into one of the mesh cages 2 through the distribution telescopic mechanism 12, and air through the mesh of cage 2 passes into chamber 1. After the loading time of the butterflies into the cage, the distribution telescopic mechanism- 12 moves and overlaps with a shutter 13 an end wall of the opening filled with mesh cage 2 and at the same time opens the opening of the next charge for a regular load. Net cages 2 are filled periodically in daily di press, which corresponds to the movement of the distribution telescopic mechanism 12 once a day.

The actuator 7 with the specified time intervals provides the oscillation of the frame 8, on which the mesh cages 2 and the pan 6 are fixed. The grain mole is in the mesh cages 2 for about four days during active lay-laying and when the frame 8 oscillates, the grain mole moves along the mesh bottom cage 2, sweeping the egg deposition through the nets onto the tray 6. A small part of the laid eggs on the side walls of the mesh cage 2 is blown off by air through the discharge duct 17, passes through the mesh bottom of the cage and wakes down onto the pan 6.

Grain moth eggs that fall on the bottom of Don 6, when the pallet oscillates, move downwards and through the chute 11 are sucked by air through the air duct 19 into the pneumatic separator 15 and further into the capacity 16 for collecting eggs. Complete removal of eggs from the pan 6 is provided by the discharge duct 17 and distributors 23 according to the number of cages.

After finishing the laying of eggs, on the fifth day, used and dead butterflies are removed from the cages, for which valve 4 is opened, and one of the supports of the corresponding cage 2 is lowered down on frame 8. With a joint oscillation of tank 2 and frame 8, butterflies are lowered from groove 11 to groove 10, and then they are removed

from chamber 1 as well as the eggs through the suction duct 19, into the tank 16 for collecting eggs.

After removing the grain moth, the flap 4 closes, the tank returns to its original horizontal position and the installation is ready for a new load. The complete installation cycle corresponds to the daily laying of the eggs of the grain moth and is carried out automatically by means of remote control.

27, which receives information from the sensor unit 25 of temperature and humidity.

The use of active mechanical separation (sifting) of eggs from the butterflies of the grain moth together with the air injection and suction flows improves the quality of the final product, as well as the capacity of the installation.
