Description

Technical Field

[0001] This utility model relates to the field of agricultural equipment technology, specifically to a rice spore collection device based on a drone. Background Technology

[0002] Rice spores mainly originate from the propagation bodies of pathogenic fungi (such as rice blast fungus and rice sheath blight fungus) and diseased rice straw and grains remaining in the field. Pathogens reproduce asexually through conidia and are spread to the surface of rice plants by wind and rain, forming an infection cycle. By analyzing spore concentration and species, outbreak trends of diseases such as rice blast can be predicted, guiding precise pesticide application. Currently, field spore monitoring equipment generally adopts a fixed installation mode, which suffers from high equipment purchase costs and complex installation and maintenance, resulting in low willingness among ordinary farmers to install and deploy such equipment. To address this pain point, the industry is exploring mobile monitoring technology, such as the drone-borne spore collection device proposed in patent CN113335514B. This device uses a stacked glass slide storage structure, but its mechanical transmission components are relatively complex, and its stability may be problematic in actual use. Moreover, this patent only includes an airflow inlet and does not design an airflow outlet path, which can easily cause spore-containing airflow to remain inside the device, contaminating the internal components and requiring frequent cleaning.

[0019] The technical solutions of the present utility model will be clearly and completely described below with reference to the accompanying drawings of the embodiments. Obviously, the described embodiments are only some embodiments of the present utility model, and not all embodiments. Based on the embodiments of the present utility model, all other embodiments obtained by those of ordinary skill in the art without creative effort are within the protection scope of the present utility model.

[0020] As attached Figure 1-6 As shown, the rice paddy spore collection device based on a drone is installed at the lower part of a quadcopter drone. The spore collection device includes a box body 1, a box cover 2, an air guide 4, and a collection tray assembly 5.

[0021] As attached Figure 1 , 2 As shown in Figures 1 and 3, the box body 1 is a hollow cavity structure. The upper opening is provided with a box cover 2 by bolts or other detachable structures. The upper part of the box cover 2 is provided with a connecting post 21 that connects to the lower part of the drone.

[0022] The collection tray assembly 5 is located inside the box body 1.

[0023] The collection tray assembly 5 includes a rotating motor and control unit 51, a rotating disk 52, several carrier grids 53, several culture dishes 54, and an air guide duct 55.

[0024] The rotating motor and control unit 51 are located at the center of the bottom surface of the housing 1. The rotating shaft of the rotating motor is connected to the rotating disk 52, which rotates under its drive. The control unit 51 controls the rotating electrode to perform its operation.

[0025] A number of through holes are provided on the rotating disk 52, and a placement ring 521 is provided at the through hole. The carrier mesh 53 is a stainless steel mesh and is detachably placed in the placement ring 521. The culture dish 54 is placed on the carrier mesh 53.

[0026] An air guide hole is provided on the side wall of the box body 1. One end of the air guide pipe 55 passes through the air guide hole and is connected to the air guide cover 4. The air guide pipe 55 and the box body 1 are fixed together by adhesive at the air guide hole. The other end of the air guide pipe 55 extends to the upper part of the placement ring 521 and is provided with an air blowing port with a diameter smaller than the placement ring 521 and larger than the culture dish 54. The air blowing port is located on the upper part of the placement ring 521 and is coaxial with the upper part of the placement ring 521.

[0027] During the drone's flight, spores are carried by the airflow through the air guide 4 and air guide 55 into the culture dish 54, thus collecting the spores. Then, the rotating motor and control unit 51 are activated, causing the rotating disk 52 to rotate, so that another culture dish 54 is rotated below the air outlet, thus achieving multiple collections.

[0028] The control unit includes a circuit board, control buttons, and a battery. The control buttons allow for "jogging" of the rotating motor (i.e., rotating it by a specific angle to move the placement ring 521 to the lower part of the air vent). Each press switches one placement ring, facilitating the placement and removal of the culture dish. During the collection process, a timed start can be set, meaning the rotating motor begins rotating a certain time after takeoff. It can also be connected to a drone remote controller for controlled "jogging." The specific circuit structure of the control unit can be obtained by those skilled in the art through adaptive design and is not within the scope of this application.

[0029] To ensure smooth airflow, an air outlet is provided on the bottom surface of the box 1 located directly below the air inlet, and an air guide ring 11 is provided at the outlet, with the top of the air guide ring 11 slightly lower than the bottom of the rotating disk 52. After the airflow passes through the air guide shroud 4 and the air guide pipe 55 and reaches the culture dish 54, the airflow flows out through the stainless steel mesh and then out through the air guide ring 11.

[0030] Furthermore, as shown in the attached document. Figure 5 As shown, in order to avoid instability and skewness that may result from the long-term use of the rotating disk 52 relying solely on the output shaft of the rotating motor and control unit 51, a raised ring 12 is provided on the lower part of the side wall of the box body 1. The top of the raised ring 12 is slightly lower than the bottom of the rotating disk 52, and several rotating beads 121 are provided on the top surface of the raised ring 12, which can provide support while ensuring the smooth operation of the rotating disk 52.

[0031] As attached Figure 4 , 6 As shown, the carrier mesh 53 is formed by welding thin stainless steel rods. Furthermore, to achieve a reliable connection of the carrier mesh 53, it includes a disc portion 531 and several limiting rods 532. The limiting rods 532 are arranged in a circumferential array on the outer side of the disc portion 531, slightly inclined outwards. Several grooves 521a are provided on the upper section of the inner wall of the placement ring 521. The top of the limiting rods 532 has an outwardly bent head. In use, the carrier mesh 53 limiting rods 532 are placed into the grooves 521a, and the carrier mesh 53 is pushed downwards until the top of the limiting rods 532 reaches the bottom of the grooves 521a. The reliable connection between the carrier mesh 53 and the placement ring 521 is achieved by the elasticity of the limiting rods 532 and the limiting head at the top.

[0032] A plurality of limiting protrusions 531a are provided on the disc portion 531 of the carrier grid 53. The limiting protrusions 531a are obtained by bending a thin stainless steel rod. The limiting protrusions 531a are arranged in a circumferential array. The culture dish is stuck on the limiting protrusions 531a to achieve a reliable connection.

[0033] The lid 2 is provided with an openable and closable retrieval door 22, which allows for convenient placement and removal of the petri dish.

[0034] In use, place several petri dishes coated with Vaseline on the carrier grid 53. Then, place the spore collection device under the drone. The drone collects spores as it flies. After collection, the drone returns, the spore collection device is removed, and the petri dishes are taken out through the retrieval cover 22 and new petri dishes are placed inside. If necessary, open the lid 2 to clean the inside. The carrier grid 53 is detachable and can be easily removed for cleaning or replacement.

[0035] It should be noted that, unless otherwise explicitly specified and limited, terms such as "installation," "connection," "joining," "fixing," and "setting" should be interpreted broadly. For example, they can refer to a fixed connection, a detachable connection, or an integral part; they can refer to a mechanical connection or an electrical connection; they can refer to a direct connection or an indirect connection through an intermediate medium; they can refer to the internal communication of two components or the interaction between two components. Those skilled in the art can understand the specific meaning of the above terms in this utility model according to the specific circumstances.
