Description

TECHNICAL FIELD

[0001] The present application relates to the technical field of pest egg mass collection, in particular to a non-destructive collection method for lepidopteran pest egg masses based on vibration separation and a portable device. BACKGROUND

[0002] Lepidopteran pests are the most serious pests in agricultural production, including cotton bollworm, corn borer, fall armyworm, diamondback moth and other major agricultural pests. This type of pest has strong reproductive capacity, with a single female laying hundreds to thousands of eggs, and the egg particles are small, often with scales and mucus on the surface, posing a great challenge to pest monitoring and biological control. In the field of biological control, accurate acquisition of pest egg masses is crucial for the mass breeding of natural enemies such as trichogramma; in the aspect of pest monitoring and early warning, rapid separation of field-collected egg masses is a fundamental step for population dynamics research. Currently, the separation of lepidopteran pest egg masses mainly relies on manual operation and mechanical separation. Manual separation uses traditional methods such as a brush, which has low efficiency and relies on the experience of the operator, making it difficult to meet the needs of large-scale applications. Mechanical separation equipment is mainly based on vibration separation and air flow separation principles, such as the "egg separator" disclosed in Chinese patents CN106733666A and CN201621400166U, which separates scales and insect eggs by combining a vibration box with an air blower. However, existing mechanical separation techniques have the following significant drawbacks:

[0003] Large volume, poor portability: existing equipment mostly adopts a fixed design, including large components such as a frame, a vibration box, and an air blower, with a total weight usually exceeding 15-20 kg, requiring special transportation tools for handling, completely unable to meet the needs of real-time monitoring and field collection. For example, the separator described in CN106733666A has a height exceeding 1.2 meters, which must be fixedly installed for use.

[0004] In view of the above technical bottlenecks, some improvements have emerged in recent years. Patent CN117562044A proposes a lepidopteran pest control method based on a specific vibration frequency, revealing the sensitivity differences of different types of pests to vibration frequency, providing a theoretical basis for optimization of vibration separation parameters; patent CN219182498U shows a simple vibration type insect pupal stage management device, verifying the feasibility of a miniaturized vibration device. However, these technologies have not fundamentally solved the problem of coordinating the portability, efficiency, and adaptability of lepidopteran pest egg mass separation equipment.

[0005] Therefore, there is an urgent need in the art to develop a lightweight, high-efficiency, and highly adaptable portable lepidopteran pest egg mass separation device to meet the growing on-site operation needs in modern agricultural pest monitoring and biological control. SUMMARY

[0071] The method comprises the following steps:

[0072] S1, different clay blocks with insect eggs are put into the entrance cavity 22, the left and right inclination angles of the entrance cavity 22 are greater than the front and back inclination angles, the left and right inclination angles are 10 degrees, the front and back inclination angles are 5 degrees, so that the different clay blocks move horizontally along the entrance cavity 22 under the action of gravity, and finally come out from different flow outlets 23.

[0073] S2, the clay blocks flowing out slide downward along the arc-shaped hopper 24, the arc-shaped partition plate 17 separates the clay blocks with different viscosities, and the clay blocks enter the connection position of the arc-shaped hopper 24 and the guide plate 16.

[0074] S3, at this time, the rotating disc 5 outside is rotated, the connecting piece 7 at the right end and the fixedly connected support 27 are driven to rotate by the rotary shaft 3, the metallic sliding block 6 fixedly connected to the outer surface of the rotary shaft 3 moves up and down in the sliding groove 19, so that vibration can be realized.

[0075] S4, when it is necessary to adjust the vibration amplitude and the brushing frequency of the brush 11, the fixed rod 10 adsorbed on the annular magnet 9 is taken symmetrically, the rotation amplitude is improved by eccentric action during rotation, the distribution of the brush 11 is that the bristles of the brush 11 on the side with higher viscosity of the clay block are thicker, and gradually become thinner to the side with lower viscosity of the clay block.

[0076] S5, the worm eggs outside the soil block is brushed, through the guide plate 16 and screen 18 fall into the receiving cavity 26 in the lower end.

[0077] Example three

[0078] When the fixed rod 10 rotates, due to the uneven distribution of mass, the moment of inertia will be different in different directions. The inertia of the ring magnet 9 is inconsistent in different directions. The moment of inertia I of the object can be expressed as:

[0079]

[0080] Where m i is the mass of the i-th small mass element in the object, r i is the distance from the mass element to the rotation axis. The ring magnet 9 is unbalanced and only one fixed point can move, which will generate periodic torque during rotation and cause vibration. The size of the centrifugal force is:

[0081] F=m·r·ω 2 .

[0082] Where m is the mass, r is the distance from the mass element to the rotation axis, and ω is the angular velocity. Due to the uneven torque, the object will experience periodic vibration when the fixed point moves.

[0083] Working principle: The soil block with worm eggs is placed in the receiving cavity 26 from the entrance cavity 22. The left and right inclination angles of the entrance cavity 22 are greater than the front and rear inclination angles, so different adhesion soil will slide to different positions. The soil with high adhesion will slide for a long time, and the soil with low adhesion will slide for a short time. The upper opening facilitates observation, reduces weight and is portable. According to the different viscosity of the soil block, the lateral movement speed of the soil block in the receiving cavity 26 is realized, the soil block with different viscosity slides from the separation area formed by the arc-shaped separation plate 17 and the arc-shaped bucket 24, and the sliding mechanism 21 is composed.

[0084] Under the action of gravity, the soil block moves downward along the arc-shaped bucket 24. The outer part is manually rotated to drive the rotating disc 5 to rotate, and the rotating shaft 3 is driven to rotate the right end of the connecting piece 7. The right end of the connecting piece 7 is provided with a support 27, the outer part of the support 27 is provided with a ring magnet 9, the outer part of the ring magnet 9 is magnetically connected with a fixed rod 10, the outer surface of the fixed rod 10 is provided with a brush 11, the brush 11 has different thicknesses, the brush 11 near the soil block with high adhesion is thicker, and the brush 11 near the soil block with low adhesion is thinner.

[0085] The outer surface of the rotating shaft 3 is fixedly connected with a metal sliding block 6, which slides up and down in a sliding groove 19 in the supporting rod 2. In order to increase the rotating amplitude and the frequency of the soil block brushing of the brush 11, the number of the fixed rods 10 is taken to make the ring-shaped magnet 9 and the bracket 27 generate an eccentric force. The number and position of the fixed rods 10 are adjusted, so that different frequencies and amplitudes of vibration can be provided during the rotation of the brush 11. The vibration is due to the unbalanced arrangement of the fixed rods 10, and the vibration can be generated during the rotation. The metal sliding block 6 only has the freedom of moving up and down, i.e. the up and down vibration can be completed. The relative sliding of the metal sliding block 6 and the sliding groove 19 realizes the vibration effect. In order to improve the stability of the metal sliding block 6 in the sliding groove 19, a strong magnet 20 is placed on the outside of the supporting rod 2. In order to improve the vibration effect, a spring 8 is tightly connected to the upper end of the connecting piece 7. The upper end of the spring 8 is fixedly connected with a pressing rod 13. The two sides of the pressing rod 13 are fixedly connected with side plates 14. The spring 8 plays a role of resetting the connecting piece 7 in time.

[0086] The lower end of the arc-shaped hopper 24 is connected with a guide plate 16. A screen 18 is arranged at the front end of the guide plate 16. The insect eggs brushed by the brush 11 roll down from the guide plate 16, fall from the screen 18 to the bottom and enter the storage cavity 26.

[0087] Although the embodiments of the present application have been shown and described, it is to be understood that various changes, modifications, substitutions and alterations can be made to the embodiments without departing from the principles and spirit of the present application, and the scope of the present application is defined by the appended claims and their equivalents.
