Abstract
Description
Technical Field
[0001] The invention relates to the technical field of plant sampling, and in particular to a rice leaf disease identification sampler. Background Art
[0002] Rice is widely cultivated as the staple food for more than half of the world's population. Its cultivated area and yield rank among the highest among cereals, making it a key cornerstone of food security. However, rice is highly susceptible to various diseases during its growing period, particularly leaf diseases such as rice blast, bacterial leaf blight, and sheath blight. Large-scale outbreaks of these diseases can severely impact rice's physiological processes, including photosynthesis and respiration, leading to reduced or even complete crop failure. Accurately and promptly identifying rice leaf diseases and implementing effective prevention and control measures are key to achieving high and stable rice yields.
[0003] The development of a leaf disease identification and sampling device aims to provide an objective, accurate, and efficient method for collecting samples for disease identification, addressing the shortcomings of manual identification. Scientific analysis of collected leaf samples allows for rapid and precise determination of disease types, providing a strong basis for subsequent precision prevention and control. Existing leaf disease identification and sampling devices typically use an image recognition device integrated into the side of a cutting blade to identify diseased spots on rice leaves. Once the diseased spots are identified, the cutting blade is used to cut and sample the rice.
[0004] However, when existing leaf disease identification and sampling devices use a cutting blade to cut and sample rice leaves with identified diseased spots, residual tissue fluid or cell fluid from the leaves adheres to the blade's surface. The presence of an image recognition device on the blade makes it difficult to clean the blade after sampling. When the sampler samples the next rice plant, this residual virus-containing fluid can easily be transferred to its leaves, leading to cross-infection of the rice virus between different rice plants and expanding the spread of the disease. Summary of the Invention
[0005] The purpose of the present invention is to overcome the problems in the prior art and provide a rice leaf disease identification sampler that can prevent tissue fluid or cell fluid from the diseased leaves from remaining on the cutting knife when sampling diseased rice leaves, thereby preventing rice viruses from cross-infecting different rice plants.

[0030] The following is combined with Figure 1-Figure 7 , the specific embodiments of the present invention are described in detail, but it should be understood that the scope of protection of the present invention is not limited by the specific embodiments. Based on the embodiments of the present invention, all other embodiments obtained by ordinary technicians in this field without making any creative efforts shall fall within the scope of protection of the present invention.
[0031] like Figure 1-Figure 7As shown, the rice leaf disease identification sampler provided by the present invention includes a housing 7, an active roller 802, a driven roller 803, an image recognizer 804, a reciprocating mechanism 101 and a first cutter 102, wherein the active roller 802 and the driven roller 803 are opposite to each other, and the active roller 802 and the driven roller 803 are both rotatably connected to the housing 7, the active roller 802 is connected to a driving device 805, and a through hole 806 is provided on the housing 7. The first cutter 102 is connected to the reciprocating mechanism 101, and the reciprocating mechanism 101 is used to drive the first cutter 102 to reciprocate along the thickness direction of the rice leaf 1. It also includes: a second cutter 103, an intermittent rotation mechanism 104 and a brushing mechanism. The second cutter 103 is a polygonal prism structure. The second cutter 103 is arranged on the lower side of the first cutter 102. The reciprocating mechanism 101 drives the first cutter 102 to move closer to the second cutter 102. When the cutter 103 moves to one side, the blade of the first cutter 102 can be in contact with the side wall of the second cutter 103 on the side close to the first cutter 102; the intermittent rotation mechanism 104 is connected to the second cutter 103, and the intermittent rotation mechanism 104 is used to drive the second cutter 103 to rotate when the blade of the first cutter 102 separates from the side wall of the second cutter 103, until the next side wall of the second cutter faces the first cutter; the brushing mechanism includes a first brush 105 and a disinfectant spraying unit 106, and the disinfectant spraying unit 106 is used to spray disinfectant onto the first brush 105. When the reciprocating mechanism 101 drives the first cutter 102 to move away from the second cutter 103, the first brush 105 is arranged on the other side of the lower end of the first cutter 102 opposite to the image recognizer 804, and the first brush 105 is in contact with both sides of the blade of the first cutter 102.
[0032] The working principle of the above embodiment is briefly described below:
[0033] A guide plate 801 is provided in the housing 7 of the sampler. The active roller 802 and the driven roller 803 are respectively provided on the upper and lower sides of the guide plate 801. The active roller 802 and the driven roller 803 are provided on one side of the second cutting knife 103. When the sampler is used to identify and sample rice with diseased spots, the rice leaf 1 with the diseased spots is inserted into the housing 7 through the through hole 806. The leaf 1 is inserted between the active roller 802 and the driven roller 803 under the guidance of the guide plate 801. The leaf 1 is clamped between the active roller 802 and the driven roller 803. The driving roller is driven to rotate by the driving device 805. The rolling roller drives the driven roller through the blade 1. The wheel rotates, and under the action of the active and driven rollers, the blade 1 is pulled between the second cutter 103 and the first cutter 102. At this time, the image recognizer 804 is used to identify the diseased spot on the blade 1. When the image recognizer 804 identifies the diseased spot on the blade 1, it controls the reciprocating mechanism 101 to move, and the reciprocating mechanism 101 drives the first cutter 102 to move closer to the second cutter 103. When the blade of the first cutter 102 contacts a side wall of the second cutter 103, the shear force applied to the blade 1 by the first and second cutters 102, 103 cuts off the blade 1 with the diseased spot, thereby completing the sampling of the blade 1. During this process, the disinfectant spraying unit 106 sprays disinfectant onto the first brush 105. Then, the reciprocating mechanism 101 drives the first cutter 102 to move away from the second cutter 103. At this point, the bristles of the first brush 105 have a certain elasticity, and the bristles of the first brush 105, which is loaded with disinfectant, can fit against both sides of the blade of the first cutter 102. The blade of the first cutter 102 moves relative to the first brush 105, thereby using the first brush 105 to scrub the blade of the first cutter 102, thereby cleaning the leaf tissue fluid or cell fluid remaining on the blade of the first cutter 102. When the reciprocating mechanism 101 drives the first cutter 102 to move until the blade of the first cutter 102 separates from the side wall of the second cutter 103, the second cutter 103 is rotated by the intermittent rotation mechanism 104 until the next side wall of the second cutter 103 faces the first cutter 102. As a result, the blade of the first cutter 102 and the side wall of the second cutter 103 facing the first cutter 102 are both clean. At this time, when the sampler is used to sample the leaves of the next rice plant, the next rice plant can be effectively prevented from being infected with the pathogens existing in the previous rice plant.
[0034] The rice leaf disease identification sampler of the present invention can prevent tissue fluid or cell fluid of the diseased rice leaf 1 from remaining on the cutting knife when sampling the diseased rice leaf 1, thereby preventing rice viruses from cross-infecting different rice plants when the sampler samples different rice plants.
[0035] On the basis of the above embodiment, in order to ensure the cleaning effect of the first brush 105 on the blade of the first cutter 102, cross infection of rice viruses between different rice plants is further prevented.
[0036] like Figure 2 and Figure 5 As shown, the disinfectant spraying part 106 is connected to a bracket 201, and a first slide groove 202 is provided on the bracket 201. The length direction of the first slide groove 202 is perpendicular to the movement direction of the first cutter 102. The first brush 105 is slidably connected in the first slide groove 202. The first brush 105 is connected to a first transmission mechanism, and the first transmission mechanism is connected to the first cutter 102. The first cutter 102 drives the first brush 105 to slide back and forth along the length direction of the first slide groove 202 through the first transmission mechanism, so that the first brush 105 intermittently fits the blade of the first cutter 102 or the disinfectant spraying part 106.
[0037] When the reciprocating mechanism 101 drives the first cutter 102 to reciprocate, thereby cutting the blade 1, the reciprocating mechanism 101 drives the first brush 105 to slide back and forth along the length direction of the first slide groove 202 through the first transmission mechanism. Since the first slide groove 202 is perpendicular to the movement direction of the first cutter 102, the movement direction of the first brush 105 is perpendicular to the movement direction of the first cutter 102, so that the first brush 105 can brush the blade of the first cutter 102. Since the reciprocating mechanism 101 drives the first cutter 102 and the first brush 105 at the same time, the first brush 105 can clean the blade of the first cutter 102 every time the first cutter 102 cuts the blade 1, thereby ensuring the cleanliness of the first brush 105 and the cleaning effect of the first brush 105 on the blade of the first cutter 102, so as to further prevent rice viruses from forming cross-infection between different rice plants when sampling rice plants.
[0038] As a preferred solution, Figure 2-Figure 4 and Figure 6As shown, the second cutter 103 is rotatably connected to the bracket 201, the disinfectant spraying part 106 is arranged on one side of the bracket 201, and the bracket 201 is provided with a second slide groove 401 along the length direction of the second cutter 103, and a connecting rod 203 is slidably connected in the second slide groove 401, and a second brush 402 is provided on the connecting rod 203. The connecting rod 203 is connected to the first cutter 102 through a second transmission mechanism, and the first cutter 102 drives the second brush 402 to slide along the length direction of the second slide groove 401 through the connecting rod 203, so that the second brush 402 intermittently fits the side wall of the second cutter 103 or the disinfectant spraying part 106. When the reciprocating mechanism 101 drives the first cutter 102 to reciprocate, thereby cutting the blade 1, the reciprocating mechanism 101 drives the second brush 402 to slide along the length direction of the second slide 401 through the connecting rod 203, so that the second brush 402 intermittently fits the side wall of the second cutter 103 or the disinfectant spraying part 106. When the second brush 402 fits the disinfectant spraying part 106, the disinfectant spraying part 106 sprays disinfectant onto the second brush 402. Then, as the reciprocating mechanism 101 is driven, the connecting rod 203 drives the second brush 402 to move toward the side close to the second cutter 103. When the second brush 402 fits the side wall of the second cutter 103, due to the second slide 401 along the length direction of the second cutter 103, direction, therefore, the second brush 402 with disinfectant can scrub the side wall of the second cutter 103 where cell fluid and tissue fluid of the leaf 1 remain, and under the drive of the reciprocating mechanism 101, the second cutter 103 rotates once each time, and the second brush 402 reciprocates once. Therefore, each time the second cutter 103 cuts a pair of leaves 1 once, the second brush 402 scrubs the side wall of the second cutter 103 once, and the second brush 402 is sprayed with disinfectant once by the disinfectant spraying part 106, so that the second brush 402 can always be kept clean, ensuring the cleaning effect of the second brush 402 on the side wall of the second cutter 103, thereby further preventing the rice virus from forming cross-infection between different rice plants when the sampler continuously samples rice plants.
[0039] As a preferred solution, Figure 2 and Figure 6As shown, the connecting rod 203 is provided with a sliding hole perpendicular to the length direction of the second cutter 103, and the second brush 402 is connected to a sliding rod 3, and the sliding rod 3 is slidably connected in the sliding hole. A spring 107 is provided on the sliding rod 3, and the spring 107 is in contact with the second brush 402. The spring 107 is used to apply an elastic force to the second brush 402 toward the side of the second cutter 103. Since the sliding hole is perpendicular to the length direction of the second cutter 103, when the second cutter 103 rotates, the edge of the second cutter 103 pushes the second brush 402 to move away from the second cutter 103. At this time, the second brush 402 drives the slide bar 3 to slide in the sliding hole toward the side away from the second cutter 103. The spring 107 is squeezed by the second brush 402. Under the action of the elastic force of the spring 107, the second brush 402 with disinfectant adheres to the side wall of the second cutter 103. Since the second cutter 103 is a polygonal prism structure, the second cutter 103 reciprocates and squeezes the spring 107 when rotating. Under the guidance of the slide bar 3 and the slide bar 3, the second brush 402 can be ensured to always adhere to the side wall of the second cutter 103, thereby ensuring the cleaning effect of the second brush 402 on the side wall of the second cutter 103.
[0040] As a preferred solution, Figure 2-Figure 7 As shown, the first transmission mechanism and the second transmission mechanism have the same structure, both including a first rack 501, a transmission shaft 502 and a first gear 503, the first rack 501 is provided on the connecting rod 203 or the first brush 105, the length direction of the first rack 501 is the same as the length direction of the first slide 202, the transmission shaft 502 is rotatably connected to the bracket 201, the first gear 503 is provided on the transmission shaft 502, the first gear 503 is gear-connected with the first rack 501, and a second gear 504 is also provided on the transmission shaft 502, the first cutter 102 is connected to the second rack 505, the second rack 505 is provided along the movement direction of the first cutter 102, and the second rack 505 is gear-connected with the second gear 504. When the reciprocating mechanism 101 drives the first cutter 102 to reciprocate along the thickness direction of the blade 1, the reciprocating mechanism 101 simultaneously drives the second transmission mechanism and the first rack 501 of the first transmission mechanism to reciprocate, and the first rack 501 drives the first gear 503 to rotate back and forth, thereby driving the transmission shaft 502 to rotate back and forth, and the transmission shaft 502 drives the second gear 504 to rotate back and forth, thereby driving the second rack 505 to reciprocate along the width direction of the blade 1, thereby driving the second brush 402 or the first brush 105 to reciprocate along the width direction of the blade 1, thereby reciprocatingly brushing the blade of the first cutter 102 and the side wall of the second cutter 103 to clean the side wall of the second cutter 103.
[0041] As a preferred solution, Figure 3-Figure 5As shown, the intermittent rotation mechanism 104 includes an overrunning clutch 601 and a grooved wheel mechanism 602, the second cutter 103 is connected to the grooved wheel mechanism 602, the grooved wheel mechanism 602 is connected to a rotating shaft 603, the rotating shaft 603 is connected to the overrunning clutch 601, the overrunning clutch 601 is connected to a third gear 604, the third gear 604 is connected to a third rack 605, and the third rack 605 is connected to the first cutter 102. Under the action of the overrunning clutch 601 and the grooved wheel mechanism 602, when the first cutter 102 moves toward the side close to the second cutter 103 and the blade of the first cutter 102 does not contact the side wall of the second cutter 103, the grooved wheel mechanism 602 drives the second cutter 103 to rotate. When the reciprocating mechanism 101 drives the first cutter 102 to move toward the side close to the second cutter 103, the first cutter 102 drives the third rack 605 to move toward the side close to the second cutter 103, and the third rack 605 drives the third gear 604 to rotate forward. At this time, the overrunning clutch 601 is engaged, and the third gear 604 drives the rotating shaft 603 to rotate forward. The rotating shaft 603 drives the second cutter 103 to rotate a certain angle through the grooved wheel mechanism 602 and then stops. At this time, the side wall of the second cutter 103 close to the first cutter 102 is parallel to the blade of the first cutter 102. When the blade of the first cutter 102 cuts through the blade 1 resting on the second cutter 103, the blade of the first cutter 102 fits against the side wall of the second cutter 103 parallel to it, thereby achieving cutting and sampling of the blade 1. When the first cutter 102 moves away from the second cutter 103, the first cutter 102 drives the third rack 605 to move away from the second cutter 103, and the third rack 605 drives the third gear 604 to reverse. At this time, the overrunning clutch 601 is disengaged, and the third gear 604 cannot drive the rotating shaft 603 to rotate. The second cutter 103 is in a stationary state. At this time, the cutting knife drives the second brush 402 to move along the length direction of the second cutter 103 through the first rack 501 and the first gear 503, thereby cleaning the side wall of the second cutter 103. Using the second brush 402 to clean the side wall of the stationary second cutter 103 can improve the cleanliness of the side wall of the second cutter 103, thereby further preventing rice viruses from forming cross infection between different rice plants when sampling rice plants.
[0042] As a preferred solution, the disinfectant spraying unit 106 is provided with a travel switch. When the first brush 105 or the second brush 402 is in contact with the disinfectant spraying unit 106, the travel switch controls the disinfectant spraying unit 106 to spray disinfectant onto the first brush 105 or the second brush 402. By providing the travel switch, when the first brush 105 or the second brush 402 moves to contact with the disinfectant spraying unit 106, the travel switch controls the disinfectant spraying unit 106 to spray disinfectant onto the first brush 105 or the second brush 402. This not only improves the automation level of the entire sampler, but also ensures the timeliness of disinfectant spraying and the scrubbing performance of the first brush 105 and the second brush 402.
