Description

The invention relates to biological protection of agricultural plants, in particular to a module for laying eggs of the sieve bug.

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 device for breeding grain moths is known from the prior art (USSR patent for invention No. 560569, IPC A01K 67/00), comprising a frame, a drum, a cassette holder with cassettes, a temperature and humidity control unit for the growing environment, characterized in that, in order to ensure a better exit of moths from the grain, it is equipped with a rotation drive for the cassette holder and an air diffuser for forced collection of moths exiting the cassettes.

The disadvantages of this invention are the lack of a corresponding compartment for collecting the eggs of the grain moth, which significantly complicates the collection process, reduces efficiency and safety, since it increases human contact with the waste products of the grain moth and its eggs. Also, the lack of elements and devices in the design intended to account for the volume of the harvest complicates the process of planning the required volume of the finished product.

The prior art discloses a device for collecting eggs for breeding lepidopteran insects (Chinese Utility Model Patent No. 215454808, IPC A01K 67/033), comprising a mounting frame, a cultivating mechanism and a temporary storage mechanism, and the left and right sides of the mounting frame are provided with arcuate supports. The cultivating mechanism includes a cultivating box, two auxiliary assembly components and an arcuate cover, wherein the cultivating box is located inside the mounting frame, and the two auxiliary collection components are respectively located at the front and back of the cultivating box. The upper end of the breeding box is provided with an arcuate interface, the arcuate cover is assembled inside the arcuate interface, and the arcuate cover slides through the right side of the breeding box and is rigidly connected to the first handle.

The temporary storage mechanism includes a fixed round plate, a rotating round plate, a net drum and an arc-shaped net. The fixed round plate is fixed to the arc-shaped support on the left side, and the rotating round plate rotates on the right. On the arc-shaped support side, the net drum is located between the fixed round plate and the rotating round plate, the net drum is rotationally connected to the fixed round plate, and the net drum is connected to the rotating round plate. The rotating round plate is rigidly connected, the front and rear sides of the right end of the fixed round plate are rigidly provided with egg brushes, which correspond to the inner wall of the mesh drum, the fixed round plate is provided with a loading hole, and the yarn The mesh drum is provided with a placement hole, the arc-shaped mesh is collected on the placement hole, the arc-shaped mesh slides through the rotating round plate and is rigidly connected to the second handle, and the right side of the rotating round plate is rigidly provided with the second handle.

The disadvantages of this invention are the lack of a drive/motor for rotating the plate, thus harvesting involves a long stay of a person/operator in the room with this installation, which significantly reduces efficiency and safety, since it increases human contact with the waste products of the grain moth and its eggs.

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

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

The technical result is achieved in that the egg-laying module of the sieve-puller contains a sealed housing with a removable cover, inside which a drum for laying eggs is placed with the possibility of rotation and periodic stopping, a drive wheel is installed on the outer side of the drum, transmitting rotation to the drum from a motor with a belt drive, a funnel is installed under the drum with a receiving tray located under it, equipped with strain gauges, and a net is stretched around the drum, preventing the sieve-puller from getting beyond its limits, while marks corresponding to the segments are placed on the drum, and a sensor is located on the inner side of the housing, detecting the mark when the drum is rotated by one segment.

The invention is further illustrated by the following figures:

Fig. 1. General view of the device for growing eggs of the sieveworm;

Fig. 2. Sectional view of the egg-laying compartment.

The egg-laying module of the sieve-treader is made in the form of a sealed housing 1 with a removable cover (not shown in the figure), a drum 2 for laying and growing eggs placed inside the housing, a motor with a belt drive 3 for rotating the drum and a compartment for harvesting 4. To enable cleaning, a hatch 5 is provided for manual and automatic cleaning of the spent segment of the drum.

Drum 2, located inside body 1, is made with six segments 6 and surrounded by net 7, preventing moths from getting beyond the drum. Under the drum, a funnel 8 is installed for separating the harvest (eggs) by collection time and a plumb line/weight 9, ensuring tension of net 7 around the drum.

Drum 2 is removable to allow cleaning between growing cycles and is held by a spring-loaded plate (not shown in the figure), while the drive wheel mounted on the outer side of the drum is non-removable and transmits rotation to the drum from engine 3.

A closing/opening sensor is installed at the bottom of the module to ensure tightness. If the drawer is not completely closed, the operator receives a notification that the drawer must be closed.

In addition, drum position sensors are located inside the module. There are marks on the drum (for example, a magnet, RFID tag or others), the number of which corresponds to the number of drum segments, they are located at an equal distance from the drum axis opposite each of the segments - "marks No. 1".

On the fixed wall of the housing on its inner side there is a magnet, an RFID tag reader - “sensor No. 1”, designed with the ability to read tags No. 1 when the drum rotates.

Thus, when the drum rotates, the sensor detects the mark and records the rotation at the level of one segment.

In addition, on the wall of the drum there is a mark No. 2 at a distance from the axis of the drum different from the distance at which "marks No. 1" are located, opposite it on the fixed wall of the housing on its inner side there is "sensor No. 2" recording a full rotation of the drum (by 360 degrees). Thus, if sensor No. 2 has recorded a full rotation of the drum by 360 degrees, and the number of sensors in the field of view of sensor No. 1 does not correspond to the number of segments in the drum, the operator receives a message about a malfunction in the drum rotation device, which allows increasing the efficiency of the device by tracking malfunctions as quickly as possible.

Description of the device operation

When entering the egg-laying module of the sieve moth, it enters drum 2 with six segments 6.

After an automatically set time, drum 2 rotates, and the moths accumulated in the drum segment, isolated by the walls of segment 6 on two sides and by mesh 7 on the third side, enter the breeding zone.

Next, after an automatically set time required for reproduction and egg laying, drum 2 spins again, and some of the moth eggs fall into the first section, for young eggs, after which the drum spins again after an automatically set time, and another portion of the eggs fall into the zone for mature eggs.

When the moth gets into the sections, it starts laying eggs on the net 7, the eggs stick to the net and then, after a certain time, the drum 2 rotates and the hard edge, like a brush, removes the eggs from the net 7. Since the net 7 has perforations suitable for the size of the egg, the eggs fall through the net 7 into the tray 10, located under the drum 2 and divided by the funnel 8 into parts corresponding to the degree of maturity of the eggs. The first eggs collected in the tray are the youngest, "category 1 maturity".

Then the cycle repeats: drum 2 spins again, the moth gets into section three. In this zone, some of the eggs that could not be peeled off from the grid 7 during one turn of the drum remain, the moth continues to reproduce and lay eggs on the grid. At the next turn of drum 2, its edge again removes the eggs, only this time over another part of tray 10, the eggs get into this tray, here are the eggs of the "2nd category of maturity".

The cycle is then repeated once again for the next section, so that tray 10 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 10, strain gauges 11 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.

After each rotation of drum 2, the device transmits a signal about the need to clean the compartment in the corresponding segment, after which the cleaning process is started in automatic mode (turns on the vacuum cleaner, removing dust from the corresponding segment). After the completion of automatic cleaning, the operator receives a signal about the completion of automatic cleaning and the need to check the segment. The operator inspects the hatch 5 in the compartment, checks whether everything is clean, and in case of residual contamination, performs manual cleaning.

In a particular case, to eliminate the need to open hatch 5 for manual inspection, the inspection hatch can be made of transparent plastic.

The cycle then repeats after each rotation.

The egg-laying module for the sieve moth increases productivity because the production cycle is continuous with minimal human involvement, reduces losses by creating favorable conditions for the moth to grow and reproduce, minimizes losses and increases safety because human contact is reduced throughout the growing cycle, reduces the amount of space required for the sieve moth to reproduce, increases productivity because several egg-laying modules can be used simultaneously, providing optimal conditions, and improves the quality of the finished product by separating the grain according to its degree of maturity and allowing for timely disposal of waste.
