Description

The invention relates to biological protection of agricultural plants, in particular to a device for growing sieve bug eggs.

Biological means of protection reduce environmental pollution with insecticides, provide long-term control over the development of major pests, and create conditions for the reproduction and accumulation of entomophages in the field.

To grow biological protection agents, certain conditions must be created. One of the key points of cultivation is nutrition. In industry, the sieve moth (grain moth) is bred for use as food for entomophages.

A system for collecting insect eggs is known from the prior art (Japanese Patent for Invention No. 2024124939, IPC A01K 67/033), which includes a cage for breeding adult insects, a mating zone inside the breeding cage, an egg-laying zone, and a light source unit emitted into the mating zone.

The disadvantages of this invention are the low safety of the system, since the outer shell is a cage that does not protect the surrounding space from pollen, which is present on the wings of insects and is dangerous and harmful to people. The second disadvantage of this invention is the lack of division of the harvest into maturity categories.

The closest technical solution is a device for laying and collecting insect eggs (USSR patent for invention No. 1581243, IPC A01K 67/00), containing a chamber with vertically arranged plates and a mesh bottom and a collector underneath, additionally equipped with two frames fixed with stops in the chamber, where one of them is installed with the possibility of reciprocating movement, and the plates are fixed between the frames and are made of elastic material.

The disadvantages of this invention are the absence of devices in the design that could regulate temperature, humidity and lighting during the process of growing insects, the lack of control over these parameters negatively affects the yield. In addition, in this invention, the butterfly gets inside the device by manually introducing the already prepared butterfly into the chamber, which significantly reduces the quality and productivity, since the process of growing, storing and transporting the butterfly is significantly complicated.

The problem that the invention is aimed at solving is to create an automated, safe device for growing sieve eggs, minimizing manual labor and increasing productivity.

The technical result achieved by the invention consists in creating an automated, safe device for growing sieve eggs, minimizing manual labor and increasing productivity.

The technical result is achieved by a device for growing sieve-eater eggs, comprising a vertically oriented compartment for growing sieve-eater eggs with a control unit and a compartment for breeding and laying eggs placed underneath it, wherein the compartment for growing sieve-eater eggs is made in the form of a cabinet with a sealed door containing air supply holes, wherein aluminum cassettes for sieve-eater-infected grain are vertically placed inside the cabinet, above which light sources are located, in the lower part of the cabinet there is a guide funnel connected to the compartment for breeding and laying eggs, which is made in the form of a sealed box and includes a housing with a removable lid, inside which a drum with segments is placed with the possibility of rotation, surrounded by a stretched net, a drive wheel is installed on the outer side of the drum, transmitting rotation to it from a motor with a belt drive placed on the outer side of the housing, a funnel for separating the crop and a tray for the crop are made under the drum.

The invention is further illustrated by the following figures:

Fig. 1. Rear view of the device for growing eggs of the sieve-brooder;

Fig. 2. Sectional view of the growing compartment of the device;

Fig. 3. Sectional view of the egg-laying compartment.

The device for growing sieve eggs includes a vertically oriented compartment for growing sieve eggs 1 with a control unit 2 and a compartment for breeding and laying 3 located underneath it.

The compartment for growing eggs of the sieve-trotter 1 is made in the form of a cabinet with a sealed door (not shown in the figure), containing air supply openings for regulating the temperature and humidity inside the compartment and an air outlet opening to ensure circulation.

Inside the cabinet, aluminum cassettes 4 filled with grain infected with sieve moth are vertically placed. In the upper part of the cabinet, above the aluminum cassettes, light sources 5 are located, facilitating the movement of the moth down the aluminum cassettes 4.

Flying out of the aluminum cassettes 4, the moth moves along the guide funnel 6, located in the lower part of the cabinet, into the compartment for reproduction and laying 3, which is made in the form of a sealed box.

On the left, on the front side of the cabinet, there are locks that allow you to fix the door (not shown in the figure) in the closed position and press it evenly against the seal along the entire height. On the right side, there are door hinges (not shown in the figure), the hinges hold the door when opening, and when closing, they press it against the seal, ensuring the necessary tightness so that the moth does not fly out of the compartment.

In the upper part of the cabinet there are wooden rods 7, which ensure the vertical position of the cassette, made with perforation so that the moth can fly out of them.

Dust from food moths can be dangerous for humans because their larvae and moths can cause allergic reactions. To increase safety and create favorable conditions, a control unit 2 is located inside the cabinet on its back wall, including a water tank 8, which includes a water level sensor and an evaporator for air humidification, a fan 9 that supplies humidified air to the cabinet, which simultaneously blows on the heaters to supply heated air to the cabinet if an increase in temperature is required, heaters with radiators 10, control electronics 11, an electric valve for supplying water to the tank 12 and an irrigation module for wetting the removed dust 13.

The egg laying and breeding section 3 is made in the form of a sealed box and includes a body with a removable lid, a motor with a belt drive 14 for rotating the drum. For cleaning, a hatch 15 is provided for manual and automatic cleaning of the spent segment of the drum.

Inside the compartment there is a drum with six segments 16, a net 17 preventing moths from getting beyond the drum, a funnel for separating the harvest (eggs) according to collection time 18, a plumb line/weight 19 ensuring the tension of the net around the drum.

The drum is removable to allow cleaning between growing cycles and is held in place by a spring loaded plate, while the drive wheel mounted on the outside of the drum is non-removable and transmits rotation to the drum from the motor.

Description of the device operation

The aluminum tubes in the 4 egg-growing compartments contain grain infected with the sifter, creating a favorable environment for reproduction. Temperature and humidity sensors, if necessary, signal changes in the environment inside the compartment to allow timely adjustment of the breeding environment.

After an automatically set time, required for the hatching and growth of the moth, light sources 5 are switched on, facilitating the movement of the moth down the aluminum cassettes.

From the control unit 2, a command is sent at automatically set intervals, and from the water tank 8, the growing compartment is irrigated to irrigate the dust and promote its settling on the walls and subsequent discharge into the sewer.

Through the funnel for direction 6, the moth enters the compartment for reproduction and laying eggs 3, inside which a drum with six segments 16 is located.

After an automatically set time, the drum 16 rotates, and the moths accumulated in the drum segment, isolated by the walls of the segment on two sides and by the mesh 17 on the third side, enter the breeding zone.

Next, after an automatically set time required for reproduction and egg laying, the drum 16 is again rotated, and some of the moth eggs fall into the first segment, for young eggs, after which the drum 16 is again rotated after an automatically set time, and another portion of the eggs fall into the zone for mature eggs.

When the moth enters the first segment, as a rule, no egg laying occurs here yet, when after a specified time the drum 16 turns, and in the second segment the moth begins to lay eggs on the mesh 17, and the eggs stick to the mesh.

Then, after a certain set time, the drum rotates, and the eggs are removed from the grid 17 by the rigid edge 20, like a brush. Since the grid has perforations suitable for the size of the egg, the eggs fall through the grid into the tray 21, located under the drum 16 and divided by the funnel 18 into parts corresponding to the degree of maturity of the eggs. The first eggs collected in the tray are the youngest, "1st category of maturity".

Then the cycle repeats: drum 15 spins again, the moth gets into segment three. In this zone, some of the eggs that could not be peeled off from the net during one turn of the drum remain, the moth continues to reproduce and lay eggs on the net. During the next turn of the drum, its edge again removes the eggs, only this time over another part of tray 17, the eggs get into this tray, here will be the eggs of the "2nd category of maturity".

The cycle then repeats once more for the next segment, so that tray 21 produces “category 3” eggs.

Separating moth eggs by maturity is of great value because the youngest eggs are the most effective at infesting grain again to start the next moth rearing cycle.

The average "2nd category of maturity" can be used both for infection, which is less effective, and for feeding entomophages. The most mature are used directly as food for entomophages.

Under the tray 21, strain gauges 22 are installed, signaling the arrival of eggs in the tray. Thanks to the information read by the strain gauges, conclusions are made about the amount of hatched grain and the breeding conditions are adjusted to create the most favorable environment.

The device for growing sieve moths increases productivity because the production cycle is continuous with minimal human involvement, reduces losses by creating favorable conditions for growing moths and conditions for their reproduction, minimizes losses and increases safety because human contact is reduced throughout the growing cycle, reduces the amount of space required for sieve moth reproduction, and improves the quality of the finished product due to the separation of grain by maturity and the possibility of timely disposal of waste.
