Detailed Implementation

[0031] 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.

[0032] Reference Figure 1 - Figure 3This utility model provides an embodiment of a multi-layer filtered rice water weevil capture device, comprising an upper barrel 1. A coarse filter 2 is detachably installed on the inner wall of the top of the upper barrel 1. The coarse filter 2 can prevent large animals or debris from entering the device and protect the internal structure. The top of the upper barrel 1 has a slot that fits the coarse filter 2, so that the coarse filter 2 can be removed from the inside of the upper barrel 1, which facilitates the cleaning of the fine filter 6. A collection bottle 5 is detachably installed on the outer wall of the bottom of the upper barrel 1 through a quick-release assembly 4. The collection bottle 5 is made of transparent acrylic material. Through its transparent appearance, the rice water weevils collected inside can be collected and observed.

[0033] Reference Figure 2 and Figure 3 A fine filter screen 6 is fixedly connected to the center of the inner wall of the upper barrel 1. This fine filter screen 6 allows for multi-stage filtration of rice weevils entering the upper barrel 1. A trapping lamp 7 is installed on the inner side wall of the upper barrel 1. The trapping lamp 7 is existing technology; it emits light of a specific wavelength to attract rice weevils into the upper barrel 1. Multiple sets of inclined plates 8 are fixedly connected to the inner wall at the bottom of the upper barrel 1. By setting multiple sets of inclined plates 8 and staggering them left and right, only rice weevils are allowed to enter the collection container, preventing them from... The bottom of the outer wall of the bottom inclined plate 8 is fixedly connected to a top post 9. The inner wall of the top of the collection bottle 5 is elastically connected to a baffle 10 through a spiral spring 11. The bottom of the outer wall of the top post 9 is in contact with the surface of the baffle 10. The contact between the two causes the collection bottle 5 to be installed at the bottom of the upper barrel 1. The top post 9 will push against the baffle 10 and rotate it around its rotation center point, thereby opening the top of the collection bottle 5 and allowing the rice water weevil to enter the interior of the collection bottle 5 for collection and capture.

[0034] Reference Figure 2 and Figure 3The baffle 10 is rotatably connected to the inner wall of the top of the collection bottle 5. One end of the spiral spring 11 is fixedly connected to the inner side wall of the top of the collection bottle 5, and the other end of the spiral spring 11 is fixedly connected to the rotation shaft of the baffle 10. The function of the spiral spring 11 is to automatically rotate and close the baffle 10 after it is no longer pressed by the top column 9, thereby closing the opening at the top of the collection bottle 5 and preventing the rice water weevil from flying out at the moment of disassembly of the collection bottle 5. The quick-release assembly 4 includes a fixing ring 41, which is fixedly connected to the outer wall of the bottom of the upper barrel 1. The outer wall of the top of the collection bottle 5 is in contact with the inner side wall of the fixing ring 41. The inner wall of the fixing ring 41 is elastically connected to a wedge through a return spring 42. 43. One end of the return spring 42 is fixedly connected to the surface of the wedge 43, and the other end of the return spring 42 is fixedly connected to the inner wall of the fixing ring 41. The function of the return spring 42 is to reset the inclined surface of the wedge 43 when it is squeezed by the outer wall of the bottle mouth at the top of the collection bottle 5 and moved by manual prying. The wedge 43 is slidably connected to the inner wall of the fixing ring 41. The outer arc surface at the top of the collection bottle 5 is provided with a slot. The end of the wedge 43 is engaged with the inner wall of the slot. The engagement between the two allows the collection bottle 5 to be fixed at the bottom of the upper barrel 1 so that it can collect and capture the rice weevil that enters the upper barrel 1. The outer side wall of the upper barrel 1 is provided with a support mechanism 3.

[0035] Reference Figure 1 and Figure 4 The support mechanism 3 includes a support frame 31. A sliding frame 32 is slidably connected to the inner wall of the top of the support frame 31. The sliding frame 32 extends along the inner wall of the support frame 31, thereby adjusting the height of the upper bucket 1 so that its height can be adjusted in real time according to the height of the rice. A pressing block 34 is elastically connected to the inner wall of the bottom of the sliding frame 32 via a limiting spring 33. One end of the sliding frame 32 away from the support frame 31 is fixedly connected to the outer side wall of the upper bucket 1. One end of the limiting spring 33 is fixedly connected to the outer wall of the pressing block 34, and the other end of the limiting spring 33 is fixedly connected to the inner wall of the bottom of the sliding frame 32. The function of the limiting spring 33 is to control the pressing block. After the block 34 moves to the inner wall of the sliding frame 32, it automatically resets to its original position. The block 34 is slidably connected to the inner wall of the bottom of the sliding frame 32. The surface of the support frame 31 has a slot. The outer wall of the block 34 contacts the inner wall of the slot. The contact between the two can fix the sliding frame 32 at multiple positions extending from the inner wall of the support frame 31. The bottom end of the support frame 31 has an internal threaded groove. The inner wall of the bottom end of the support frame 31 is threaded and connected to a threaded seat 35. The threaded seat 35 can be used to move the support frame 31 downwards through the threaded groove, so that it can enter the soil at the edge of the paddy field or the ridge, thereby supporting and fixing the overall placement position.

[0036] Working principle: The trapping lamp 7 is located on the inner side wall of the upper barrel 1. It emits light of a specific wavelength. This special wavelength of light can induce a phototactic response in rice water weevils in the paddy field environment, causing them to fly towards the light source, that is, towards the upper barrel 1, thus entering the upper barrel 1 and starting the first step of the capture process. After the rice water weevils enter the upper barrel 1, they will first encounter the coarse filter 2. The coarse filter 2 is installed on the inner wall of the top of the upper barrel 1. Its pores are relatively large, and its main function is to block birds, large insects, and large objects or debris such as branches and leaves that may be mixed in from entering the device, thus preventing them from entering. These objects damage the internal fine structure and also prevent them from interfering with the subsequent capture process. After initial screening by the coarse filter 2, the rice water weevil continues to fly downwards and comes into contact with the fine filter 6. The fine filter 6 is located in the center of the inner wall of the upper barrel 1. Its pores are smaller, which can filter the rice water weevil more finely, allowing only rice water weevils of a certain size to pass through, further screening the target pests and improving the accuracy of capture. After passing through the fine filter 6, the rice water weevil will reach the area where multiple sets of inclined plates 8 are located. These inclined plates 8 are arranged in a staggered manner on the inner wall of the bottom of the upper barrel 1. Due to their special... The arrangement of the weevils ensures they can only move towards the collection bottle 5 along the inclined direction of the inclined plate 8, making it difficult for them to escape in the opposite direction. This effectively guides the weevils towards the collection bottle 5. When the weevils reach the bottom of the inclined plate 8, the top post 9, fixedly connected to the bottom of the outer wall of the inclined plate 8, comes into contact with the baffle 10, elastically connected to the inner wall of the top of the collection bottle 5 via a spiral spring 11. When the collection bottle 5 is installed at the bottom of the upper barrel 1, the top post 9 applies a force to the baffle 10, causing it to rotate around the center point of rotation. This opens the opening at the top of the collection bottle 5, allowing the weevils to escape. Successfully enter the collection bottle 5 and complete the collection and capture process. When it is necessary to disassemble the collection bottle 5, such as to check the collection situation or clean the inside, manually move the wedge 43 to overcome the elastic force of the return spring 42 and make the wedge 43 slide inward, disengaging from the slot of the collection bottle 5. At this time, the collection bottle 5 can be removed from the bottom of the upper barrel 1. Due to the design of the baffle 10 and the spiral spring 11, the baffle 10 will cancel the contact with the top post 9 at the moment the collection bottle 5 is removed, and automatically close the top opening of the collection bottle 5 to prevent rice water weevils from flying out, ensuring the effectiveness of the collection process and the convenience of subsequent operations.

[0037] When the device is placed on the edge or ridge of the paddy field, the threaded seat 35 is rotated to move downwards along the threaded inner wall of the support frame 31 until it enters the soil. Through friction and embedding with the soil, the support frame 31 is firmly fixed to the ground, providing stable support for the entire capture device and preventing it from tipping over or shifting due to wind, collisions, or other factors during use. When it is necessary to adjust the height of the upper bucket 1 to accommodate rice of different heights, the button 34 is pressed. The button 34 slides downwards along the inner wall of the bottom of the sliding frame 32, compressing the limit spring 33. At this time, the button 34 disengages from the slot on the surface of the support frame 31, and the sliding frame 32 can slide freely up and down on the inner wall of the support frame 31, causing the upper bucket 1 to rise or fall. After adjusting to a suitable height, the button 34 is released, and the button 34 is reset under the elastic restoring force of the limit spring 33. Its outer wall is re-engaged into the slot on the surface of the support frame 31, fixing the height of the sliding frame 32 (that is, the upper bucket 1). This realizes the flexible adjustment of the device height, enabling it to better adapt to the height changes of rice at different growth stages in the paddy field and improve the capture efficiency.

Although the present utility model has been described in detail with reference to the foregoing embodiments, those skilled in the art can still modify the technical solutions described in the foregoing embodiments or make equivalent substitutions for some of the technical features.
