Description

Technical Field

[0001] This utility model relates to the field of agricultural machinery technology, and in particular to a rice disease and pest detection device. Background Technology

[0002] As a major food crop, rice is frequently attacked by various pests throughout its growth cycle, severely impacting its yield and quality. To effectively control pests, timely and accurate monitoring of pest species, density, and occurrence patterns in the field is crucial. Therefore, setting up various pest detection devices in rice fields has become a routine agricultural technique.

[0003] Most existing pest detection devices utilize the phototaxis of pests, using attractive lights to lure them to the collection area. However, these devices often have structural deficiencies in the sample collection process. Their sampling mechanisms are typically simple drawers or collection boxes. In uneven and complex environments like outdoor fields, the drawers are prone to shaking, tilting, or even jamming when operators pull them out. This not only affects the smoothness of operation but may also cause collected pest samples to fall out, become mixed with other samples, or be damaged, thus affecting the accuracy of subsequent detection and analysis.

[0004] Furthermore, the outdoor natural environment is highly variable; wind direction, wind force, and sudden rainfall can all interfere with the effectiveness of pest trapping and the normal operation of the device. Traditional detection devices have relatively fixed structures and lack the ability to adapt to these environmental factors. For example, they cannot effectively guide airflow according to wind direction to improve trapping efficiency, nor can they provide timely shelter for critical components during rain. This design deficiency significantly reduces the reliability and stability of the device under complex weather conditions.

[0005] Therefore, this utility model proposes a rice disease and pest detection device to overcome the shortcomings of the prior art. Utility Model Content

[0006] In view of the problems existing in the rice disease and pest detection device, such as poor stability of the sampling drawer during the pulling process, easy shaking and displacement, and difficulty in adjusting the airflow direction and providing rain protection according to environmental changes, this utility model aims to provide a rice disease and pest detection device with an improved structure that can effectively solve the above problems.

[0007] This utility model provides a rice disease and pest detection device, including: a base platform, a support column, a detection chamber, an attraction lamp, a sampling drawer assembly, and a transmission assembly.

[0008] The bottom end of the support column is fixedly connected to the base platform; the detection chamber is fixedly connected to the top end of the support column; the attraction light is located below the detection chamber; the sampling drawer assembly is installed below the detection chamber, and the sampling drawer assembly includes a drawer body and a sliding rod; the transmission assembly includes a turntable, a transmission rod, and adjustable blades.

[0009] The sampling drawer assembly also includes a limiting plate fixed within the detection chamber structure. The limiting plate has a guide groove, and the side wall of the drawer body slides within the guide groove.

[0010] Furthermore, the transmission rod is vertically arranged, and its lower end is coaxially rotatably connected to the turntable.

[0011] The transmission assembly also includes a transmission wheel, which is fixedly connected to the rod body of the transmission rod.

[0012] The adjustable blade is pivotally connected to the outside of the detection chamber, and one end of the adjustable blade is engaged with the transmission wheel.

[0013] Preferably, the sliding rod is fixedly connected to the front outer wall of the drawer body.

[0014] Preferably, to achieve multi-point adjustment, there are multiple adjustable blades, and the multiple adjustable blades are arranged at intervals along the axial direction of the transmission rod; correspondingly, multiple transmission wheels corresponding one-to-one with the adjustable blades are fixedly connected to the transmission rod.

[0015] Based on the above configuration, the plurality of adjustable blades are preferably evenly distributed around the outer periphery of the detection chamber.

[0016] Preferably, the rice disease and pest detection device further includes a protective top cover, which is fixedly connected to the top of the detection chamber.

[0017] Preferably, the rice disease and pest detection device further includes a base support, which is fixedly connected to the bottom of the base platform.

[0020] This utility model has the following beneficial effects: 1. This utility model solves the problem in the prior art that the sampling drawer is prone to shaking or shifting during the pulling process, which leads to inconvenience or failure in sample collection, by setting a limiting plate with a guide groove and making the drawer body of the sampling drawer assembly slide in cooperation with it. This achieves the technical effect of improving the stability and accuracy of sampling operation.

[0021] 2. This utility model, by setting up a transmission component that links a turntable, a transmission rod, and a transmission wheel, realizes the synchronous rotation adjustment of multiple adjustable blades, which solves the problems of poor adaptability of existing pest detection devices to natural environments such as airflow and rainwater, and inconvenient adjustment of trapping efficiency. It achieves the technical effect of optimizing the trapping environment with simple structure and convenient operation.

[0022] 3. This utility model integrates a stable sampling drawer structure with an adjustable blade transmission structure into a single design. The overall structure is compact and the functions are well coordinated. While ensuring accurate sampling, it enhances the device's adaptability to outdoor environments and improves its overall practical value. Attached Figure Description

[0025] To make the objectives, technical solutions, and advantages of this utility model clearer, the technical solutions in the embodiments of this utility model will be clearly and completely described below with reference to the accompanying drawings. Obviously, the described embodiments are only a part of the embodiments of this utility model, and not all of them. All other embodiments obtained by those skilled in the art based on the embodiments of this utility model without creative effort are within the scope of protection of this utility model.

[0026] Example: Please refer to Figures 1 to 4 This utility model provides a rice disease and pest detection device, which aims to solve the problems in the prior art where the sampling drawer assembly has poor stability and is prone to shaking and displacement during the pulling process, and the device is difficult to adjust the airflow direction and provide rain protection according to environmental changes.

[0027] like Figure 1 As shown, the rice disease and pest detection device includes a base platform 5, with base legs 6 fixedly connected to the bottom of the base platform 5. The base platform 5 and base legs 6 together form a stable foundation for the device. The bottom end of the support column 3 is fixedly connected to the base platform 5, and the detection chamber 1 is fixedly connected to the top of the support column 3. The protective top cover 2 is fixedly connected to the top of the detection chamber 1 to protect the detection chamber 1. The attraction lamp 8 is located below the detection chamber 1 and is fixed to the bottom of the detection chamber 1 through the lampshade base 7. The sampling drawer assembly 4 is installed below the detection chamber 1 and includes a drawer body and a sliding rod 402. The sliding rod 402 is fixedly connected to the front outer wall of the drawer body. The transmission assembly 9 is located outside the device and includes a turntable 904, a transmission rod 901, and an adjustable blade 903.

[0028] To solve the above-mentioned technical problems, the technical solution of this embodiment is that the sampling drawer assembly 4 and the transmission assembly 9 have a specific structural fit and connection relationship; Please refer to the following carefully. Figure 1 and Figure 3 The following is a detailed description of the stable structure of the sampling drawer assembly 4: The sampling drawer assembly 4 also includes a limiting plate 401, which is fixed inside the detection chamber 1 structure. The limiting plate 401 has a guide groove, and the side wall of the drawer body slides into the guide groove of the limiting plate 401. This sliding guide structure ensures that the drawer body always moves stably along the predetermined trajectory during the pulling process, effectively avoiding shaking and deviation during operation. Please refer to further details. Figure 1 , Figure 2 and Figure 4 The linkage structure of the transmission assembly 9 is described in detail below: The transmission rod 901 of the transmission assembly 9 is set vertically, and the lower end of the transmission rod 901 is rotatably connected to the turntable 904 on the same axis. The transmission wheel 902 is fixedly connected to the rod body of the transmission rod 901. The adjustable blade 903 is pivotally connected to the outside of the detection chamber 1, and one end of the adjustable blade 903 is meshed with the transmission wheel 902. When the turntable 904 is manually rotated, the turntable 904 drives the transmission wheel 902 to rotate synchronously through the transmission rod 901, and then the adjustable blade 903 rotates synchronously through meshing transmission, realizing the unified adjustment of airflow guidance and rainproof angle.

[0029] Based on the above embodiments, the present invention may further include the following preferred technical solutions: As a preferred embodiment, please refer to Figure 1 and Figure 2 The number of adjustable blades 903 is multiple, and the multiple adjustable blades 903 are arranged at intervals along the axial direction of the transmission rod 901; multiple transmission wheels 902 are fixedly connected to the transmission rod 901, and the multiple transmission wheels 902 correspond one-to-one with the multiple adjustable blades 903; furthermore, the multiple adjustable blades 903 are evenly distributed around the outer periphery of the detection chamber 1.

[0030] As another preferred embodiment, please refer to Figure 2 and Figure 4 The transmission wheel 902 is a gear, and the adjustable blade 903 is provided with a linkage structure that meshes with the gear. This gear meshing transmission ensures that the rotation of the transmission rod 901 can be accurately transmitted to the adjustable blade 903.

[0031] The working principle of this utility model is as follows: When pest detection and adjustment are required, the operator manually rotates the turntable 904 of the transmission assembly 9. The rotation of the turntable 904 drives the vertically mounted transmission rod 901 to rotate via a coaxial rotation connection, and the transmission wheel 902 fixed on the transmission rod 901 rotates accordingly. Since the transmission wheel 902 is engaged with one end of the adjustable blade 903 pivotally connected to the outside of the detection chamber 1, the rotation of the transmission wheel 902 drives the adjustable blade 903 to pivot synchronously, thereby changing the blade angle and achieving airflow guidance and rain protection adjustment. At the same time, the attraction lamp 8 is activated and illuminated. Under the combined guidance of the light and airflow, pests gather towards the detection chamber 1. When it is necessary to collect pest samples, the operator pulls out the sliding rod 402 of the sampling drawer assembly 4, which drives the drawer body to slide outward. During the pulling process, the side wall of the drawer body always slides and engages within the guide groove on the limiting plate 401. This guiding engagement structure between the limiting plate 401 and the drawer body provides precise guidance and limitation for the drawer body, strictly limiting its movement trajectory. This effectively solves the problems of unstable pulling and easy shaking and deviation, ensuring the stability and convenience of sample collection. Throughout the process, the base platform 5, base legs 6, supporting column 3, protective top cover 2, and lampshade base 7 together provide a stable and reliable installation and protective foundation for the device. The above description is merely a specific embodiment of this utility model, but the protection scope of this utility model is not limited thereto. Any variations or substitutions that can be easily conceived by those skilled in the art within the technical scope disclosed in this utility model should be included within the protection scope of this utility model. Therefore, the protection scope of this utility model should be determined by the protection scope of the claims.
