Description

Technical Field

[0001] This invention relates to the field of rice panicle sampling technology, specifically to a sampling device and method for detecting effective panicles in rice breeding. Background Technology

[0002] Rice panicle sampling can provide information on the growth and quality of rice in farmland, helping farmers understand the health status and growth level of the paddy fields. By obtaining timely growth data, farmers can adjust and optimize agricultural production management according to actual conditions, including fertilization, irrigation, and pest and disease control, thereby improving rice yield and quality. Rice panicle sampling can also provide information on the nutrient content and pest and disease status of the rice, helping farmers understand the nutrient status and pest and disease risks of the paddy fields. Based on the sampling results, farmers can apply fertilizers and pesticides in a targeted manner, avoiding excessive fertilization and pesticide abuse, reducing resource waste and environmental pollution, and improving agricultural production efficiency. When breeding rice, it is necessary to sample and test the effective panicles.

[0003] Publication No. CN118067428A discloses an automated sampling device for rice ears in smart agriculture fields. This device can automatically perform rice ear threshing and sampling, and can store grains from different sampling areas in separate zones. This allows for intelligent field management based on the growth status of the stored grains, eliminating the need for manual sampling on-site. The device can also perform zoned sampling for pests, offering multiple functions. However, this patent still has the following problems in practical use: While this intelligent agricultural field rice panicle automated sampling device can achieve rice panicle threshing and sampling by utilizing the cooperation of fixed and vibrating comb teeth, it cannot adjust accordingly to different growth stages of rice. Some rice plants grow taller and have denser panicles, while others are shorter and have sparser panicles due to malnutrition. This results in incomplete sampling of some panicles, affecting the accuracy of the sampling. In addition, some rice branches and leaves are collected into the rice collection chamber during the sampling process. When the rice panicles need to be tested, the branches and leaves need to be removed, which not only affects the efficiency of the test but also increases the labor intensity of workers and is not conducive to saving labor costs.

[0004] Therefore, a sampling device and method for detecting effective panicles in rice breeding are proposed to solve the problems mentioned above. Summary of the Invention

[0005] The purpose of this invention is to provide a sampling device and method for effective panicle detection in rice breeding, to solve the problems mentioned in the background art. Due to the different growth states of rice, some rice plants grow taller and have denser panicles, while others are shorter and have sparser panicles due to malnutrition. This makes it impossible to adjust the sampling according to the different growth states of rice, resulting in incomplete sampling of some panicles, thus affecting the accuracy of panicle sampling. Furthermore, during panicle sampling, some rice branches and leaves are collected into the rice collection chamber. When panicle testing is required, the branches and leaves need to be removed, which not only affects the efficiency of testing but also increases the labor intensity of workers and is not conducive to saving labor costs.

The accordion cover can protect the lifting top frame and lifting base frame from dust, preventing dust from entering the interior of the lifting top frame and lifting base frame and affecting the lifting double-threaded rod and lifting sliding rod, thus affecting the lifting and moving of the entire mobile vehicle.

[0023] Compared with the prior art, the beneficial effects of the present invention are as follows: This sampling device and method for detecting effective panicles in rice breeding moves the rice panicles towards the inside of the sampling box, avoiding the phenomenon of the rice panicle threshing sampling box being damaged during threshing sampling, thus affecting the efficiency of rice panicle threshing sampling. The second connecting shaft drives the second rotating shaft and the second threshing rod to rotate counterclockwise, enabling threshing of the rice panicles from the bottom, improving the integrity of rice threshing and avoiding incomplete threshing, which would affect the accuracy of the detection data. The bellows protective cover can protect the lifting top frame and lifting bottom frame from dust, preventing dust from entering the interior of the lifting top frame and lifting bottom frame, thus affecting the lifting bidirectional threaded rod and lifting sliding rod, and affecting the lifting and moving of the entire mobile vehicle. The specific details are as follows: 1. By setting up a threshing and sampling mechanism, not only can the first rotating motor drive the first rotating gear to rotate, but also the meshing connection between the first rotating gear and the first meshing gear ring can cause the first meshing gear ring to drive the rotating connecting ring, connecting bracket, and second connecting ring to rotate. Simultaneously, the rotating connecting ring drives the first rotating shaft and the first threshing rod to rotate clockwise, moving the rice ears towards the inside of the sampling box and avoiding the phenomenon of the rice ear threshing sampling box being obstructed during threshing sampling, thus affecting the efficiency of rice ear threshing sampling. At the same time, the second rotating motor is activated to drive the rotating worm gear to rotate. Utilizing the meshing connection between the rotating worm gear and the rotating worm wheel, the rotating worm wheel drives the second connecting shaft, the second meshing gear ring, and the second rotating shaft to rotate counterclockwise. Utilizing the meshing connection between the second meshing gear ring and the second rotating gear, the second rotating gear drives the first rotating shaft and the first threshing rod to rotate clockwise, thus... The process involves moving the rice ears towards the inside of the sampling box, while the first threshing rod performs initial threshing. The second connecting shaft drives the second rotating shaft and the second threshing rod to rotate counterclockwise, enabling threshing of the rice ears from the bottom, improving the integrity of threshing and preventing incomplete threshing that could affect the accuracy of the test data. The sieve at the bottom of the sampling box separates the rice ears and branches. Simultaneously, the conveyor motor drives the conveyor auger to rotate, transporting the threshed rice ears to the connecting pipe. The collection bag is then placed over the outside of the connecting pipe, and the fixing knob is rotated to rotate the fixing bolt. Utilizing the threaded connection between the fixing bolt and the fixing sleeve, the fixing bolt moves the clamping block, which clamps the collection bag for easy collection of rice ears. The rotating motor drives the rotating connecting shaft and the sampling box to rotate, discharging the rice branches and leaves. 2. By setting up a lifting collection mechanism, not only can the rice ears to be tested be classified and stored using collection boxes and collection bags, but the lifting motor can also be activated to drive the sprocket transmission assembly and the lifting double-sided threaded rod to rotate. This causes the lifting threaded sleeve to move relative to the outside of the lifting double-sided threaded rod, while simultaneously moving the top rotating support. Under the action of the lifting rotating rod and the rotating connecting shaft, the bottom rotating support and the lifting sliding sleeve can be moved, allowing the lifting sliding sleeve to move relative to the outside of the lifting sliding rod. The connecting spring can fix the lifting sliding sleeve to the lifting base frame, and the moving wheels can move the entire mobile vehicle. At the same time, the height of the mobile vehicle can be adjusted, facilitating random sampling of rice at different heights, making the sampled rice ears more representative. The accordion cover can be used to protect the lifting top frame and lifting base frame from dust, preventing dust from entering the interior of the lifting top frame and lifting base frame and affecting the lifting double-sided threaded rod and the lifting sliding rod, thus affecting the lifting and movement of the entire mobile vehicle.

[0031] Please see Figure 1 , Figures 9-11The lifting and collecting mechanism 2 includes a mobile vehicle 201. A sampling trough 202 is provided inside the mobile vehicle 201. An installation slot 203 is provided near the center of the sampling trough 202. A collection box 204 is fixedly installed on one side of the top of the mobile vehicle 201. Several collection bags 205 are placed inside the collection box 204. A handle 206 is fixedly installed on one side of the mobile vehicle 201 near the collection box 204. A rotating slot 207 is provided inside the mobile vehicle 201. Lifting top frames 208 are symmetrically installed at the bottom of the mobile vehicle 201.

The moving wheels 223 are fixedly installed on both sides of the bottom of the lifting base frame 221. The rice ears to be tested are classified and stored using the collection box 204 and the collection bag 205. At the same time, the lifting motor 210 is started to drive the sprocket transmission assembly 211 and the lifting double-threaded rod 212 to rotate. This causes the lifting threaded sleeve 213 to move relative to the outside of the lifting double-threaded rod 212, thereby driving the top rotating support 214 to move. Under the action of the lifting rotating rod 215 and the rotating connecting shaft 216, the bottom rotating support 217 moves. The movement of 7 and the lifting sliding sleeve 218 allows the lifting sliding sleeve 218 to move relative to the outside of the lifting sliding rod 219.

The bellows cover 222 can be used to protect the lifting top frame 208 and the lifting base 221 from dust, preventing dust from entering the interior of the lifting top frame 208 and the lifting base 221, thereby affecting the lifting bidirectional threaded rod 212 and the lifting sliding rod 219, and affecting the lifting and moving of the entire mobile vehicle 201.

[0032] Working principle: Before using this sampling device and method for detecting effective panicles in rice breeding, it is necessary to check the overall condition of the device to ensure it can operate normally. Figure 1 - Figure 11 As shown, firstly, the rice ears to be tested are classified and stored using the collection box 204 and collection bag 205. Simultaneously, the lifting motor 210 is activated, driving the sprocket transmission assembly 211 and the lifting bidirectional threaded rod 212 to rotate. This causes the lifting threaded sleeve 213 to move relative to the outside of the lifting bidirectional threaded rod 212, simultaneously moving the top rotating support 214. Under the action of the lifting rotating rod 215 and the rotating connecting shaft 216, the bottom rotating support 217 and the lifting sliding sleeve 218 move, causing the lifting sliding sleeve 218 to move relative to the outside of the lifting sliding rod 219. The connecting spring 22 then... The lifting sliding sleeve 218 and the lifting base frame 221 can be fixed, and the entire mobile vehicle 201 can be moved using the moving wheels 223. At the same time, the height of the mobile vehicle 201 can be adjusted to facilitate random sampling of rice at different heights, making the sampled rice ears more representative. The accordion cover 222 can be used to protect the lifting top frame 208 and the lifting base frame 221 from dust, preventing dust from entering the interior of the lifting top frame 208 and the lifting base frame 221, thereby affecting the lifting bidirectional threaded rod 212 and the lifting sliding rod 219, and affecting the lifting and moving of the entire mobile vehicle 201.

[0033] Secondly, the first rotating motor 102 drives the first rotating gear 103 to rotate. Utilizing the meshing connection between the first rotating gear 103 and the first meshing gear ring 104, the first meshing gear ring 104 drives the rotating connecting ring 105, the connecting bracket 106, and the second connecting ring 107 to rotate. Simultaneously, the rotating connecting ring 105 drives the first rotating shaft 108 and the first threshing rod 109 to rotate clockwise. This moves the rice ears towards the inside of the sampling box 101, preventing the rice ear threshing sampling box 101 from being obstructed during threshing sampling, thus improving the efficiency of rice ear threshing sampling. At the same time, the second rotating motor 113 is activated, driving the rotating worm gear 114 to rotate. Utilizing the meshing connection between the rotating worm gear 114 and the rotating worm wheel 115… The characteristics of the worm gear 115 cause the second connecting shaft 116, the second meshing gear ring 117, and the second rotating shaft 118 to rotate counterclockwise. Utilizing the meshing connection between the second meshing gear ring 117 and the second rotating gear 110, the second rotating gear 110 drives the first rotating shaft 108 and the first threshing rod 109 to rotate clockwise. This allows the rice ears to move towards the interior of the sampling box 101, while the first threshing rod 109 performs preliminary threshing. The counterclockwise rotation of the second rotating shaft 118 and the second threshing rod 119 by the second connecting shaft 116 allows for threshing from the bottom of the rice ears, improving the completeness of threshing and preventing incomplete threshing that could affect the accuracy of the test data.

[0034] Finally, the rice ears and rice branches and leaves are screened using the screening screen 121 at the bottom of the sampling box 101. At the same time, the conveyor motor 122 is started to drive the conveyor auger 123 to rotate. The conveyor auger 123 is used to transport the threshed rice ears to the connecting pipe 125. The collection bag 205 is put on the outside of the connecting pipe 125, and the fixing knob 128 is turned to drive the fixing bolt 127 to rotate. Taking advantage of the threaded connection between the fixing bolt 127 and the fixing sleeve 126, the fixing bolt 127 drives the clamping block 129 to move. The clamping block 129 clamps the collection bag 205 to facilitate the collection of rice ears. The rotating motor 130 drives the rotating connecting shaft 131 and the sampling box 101 to rotate, which can discharge the rice branches and leaves.
