Description

Technical Field

[0001] This invention relates to the field of soybean seed testing technology, and in particular to an automated soybean seed testing instrument. Background Technology

[0002] When conducting soybean plant evaluation, in addition to taking pictures to collect phenotypic data of soybean plants, it is also necessary to remove soybeans from the plants to record data such as the number of seeds per plant and the average weight of a single seed. At the same time, it is also necessary to take pictures of the soybeans to obtain phenotypic data.

[0003] In existing technologies, the harvesting of soybean seeds from individual plants is mostly done manually, which is not only difficult to operate and has low efficiency, but also prone to missed harvesting. In addition, the harvested soybean plants cannot be easily processed.

[0004] Although threshing equipment can be used to thresh individual soybean plants, after threshing, operators still need to manually remove the threshed soybean grains and transfer them to the seed testing tray for counting, weighing, and photographing. This process has a low degree of automation and a significant impact on seed testing efficiency.

[0005] Therefore, it is necessary to invent an automated soybean seed testing instrument to solve the above problems. Summary of the Invention

[0006] The purpose of this invention is to provide an automated soybean threshing instrument, which offers higher threshing efficiency compared to traditional manual threshing. Compared to traditional threshing equipment, it eliminates the need for transferring threshed soybean grains after threshing, resulting in a higher degree of automation and significantly improved threshing efficiency. This addresses the problem mentioned in the background art where the threshing of individual soybean plants is mostly done manually, which is not only difficult and inefficient but also prone to missed threshing. Furthermore, the threshed soybean plants are not easily processed. Although threshing equipment can be used to thresh individual soybean plants, after threshing, operators still need to manually remove the threshed soybean grains and transfer them to a threshing tray for counting, weighing, and photographing, resulting in low automation and a significant impact on threshing efficiency.

[0021] The technical solutions of the embodiments of the present invention will be clearly and completely described below with reference to the accompanying drawings. Obviously, the described embodiments are only some embodiments of the present invention, and not all embodiments. Based on the embodiments of the present invention, all other embodiments obtained by those skilled in the art without creative effort are within the scope of protection of the present invention.

[0022] This invention provides, for example Figures 1-7 The soybean automated seed testing instrument shown includes a weighing component 1, a threshing component 2 arranged on the top left side of the weighing component 1, and a stalk crushing component 3 nested in the middle of the right side of the weighing component 1. A separation counting component 4 is arranged at the top of the inner cavity of the weighing component 1, a phenotypic data acquisition component 5 is arranged at the bottom of the separation counting component 4, and a soybean particle distribution component 6 is arranged below the phenotypic data acquisition component 5.

[0023] like Figure 3As shown, the weighing component 1 includes a high-strength cast iron base 11 with a powder-coated surface. The cast iron material ensures overall stability, while the powder coating enhances rust and corrosion resistance, making it suitable for various environments, including laboratories and fields. A 304 stainless steel casing 12 is fixedly mounted on the top right side of the base 11, offering lightweight, wear-resistant, and easy-to-clean properties. This prevents soybean debris residue from breeding bacteria and also withstands impacts and friction during long-term use. An electronic weighing device 13 is installed on the top left side of the base 11, and a food-grade PP soybean particle container 14 is placed on top of the electronic weighing device 13. This container is non-toxic, odorless, and has a smooth surface. To prevent contamination of soybean particles and to avoid soybean particles sticking together, facilitating subsequent cleaning, a stainless steel guide plate 15 is fixedly installed on the top left side of the inner cavity of the casing 12. The inner side is coated with polytetrafluoroethylene to reduce the coefficient of friction between soybean particles and soybean stalks and the plate surface, ensuring that the soybean particles slide smoothly without residue. A control cabinet 16 is fixedly installed on the top left side of the casing 12. The control cabinet 16 contains a PLC controller, and the signal output terminal of the PLC controller is connected to a computer. A display 17 is fixedly installed on the top left side of the control cabinet 16. Both the electronic weighing device 13 and the display 17 are electrically connected to the PLC controller inside the control cabinet 16.

[0024] By setting up the above structure, the soybean particles output through the output tube B633 fall into the soybean particle receiving cup 14 after output. Then, the electronic weighing device 13 weighs the soybean particles inside the soybean particle receiving cup 14 and sends the weighing data to the PLC controller inside the control cabinet 16. The PLC controller then displays the weight of the soybean particles on the display 17.

[0025] like Figure 4 As shown, the threshing assembly 2 includes a threshing hopper 21 fixedly installed on the top left side of the casing 12 and made of high manganese steel. High manganese steel has high strength and impact resistance. Two mutually symmetrical guide plates A22 are fixedly installed on the top inner side of the threshing hopper 21. The guide plates are made of 304 stainless steel, with a polished surface, which ensures smooth guidance, prevents jamming of soybean plants, and is corrosion-resistant and not easily deformed. Two eccentric shafts 23 are rotatably nested on the bottom inner side of the threshing hopper 21 through bearings. Gears A24 are fixedly sleeved on the front outer side of each of the two eccentric shafts 23 and the two gears A24 mesh with each other. A motor A25 is fixedly installed on the rear side of the threshing hopper 21 and is connected to the adjacent eccentric shaft 23 for transmission. The motor A25 is electrically connected to the PLC controller inside the control cabinet 16.

[0026] By setting up the above structure, when a single soybean plant is vertically placed into the threshing hopper 21 with the top opening, the two guide plates A22 guide the soybean plant during the placement process, so that the soybean plant accurately enters between the two eccentric shafts 23. The motor A25 drives the two eccentric shafts 23 to rotate continuously through the two gears A24. When the two eccentric shafts 23 rotate, they continuously knock on the soybean plant, so that the soybean grains are released from the pods. Subsequently, the soybean stems and the released soybean grains fall onto the top of the guide plate 15 and are guided by the guide plate 15 to the conveyor belt 41.

[0027] like Figure 5 As shown, the stalk crushing assembly 3 includes a crushing hopper 31 fixedly nested at the bottom right side of the housing 12. The hopper is made of 304 stainless steel, which is high-strength and can withstand the impact of stalks during crushing, preventing deformation. A guide plate B32, made of engineering plastic, extending to the outside of the crushing hopper 31, is fixedly installed at the bottom inner side of the hopper 31. This guide plate is smooth and wear-resistant, guiding the crushed stalk fragments to flow smoothly without residue. Two crushing rollers 33 are nested within the hopper 31 via bearings. Gears B34 are fixedly fitted onto the front ends of both rollers 33, and the two gears B34 mesh with each other. A motor B35, which is connected to the adjacent crushing rollers 33, is fixedly installed at the rear of the hopper 31. The motor B35 is electrically connected to the PLC controller inside the control cabinet 16.

[0028] By setting the above structure, soybean stalks can fall into the crushing hopper 31 through the top opening of the crushing hopper 31. At this time, the motor B35 drives the two crushing rollers 33 to rotate continuously through the two gears B34, thereby crushing the soybean stalks. The crushed soybean stalk fragments are output through the guide plate B32.

[0029] like Figure 6As shown, the separation and counting assembly 4 includes a conveyor belt 41 installed at the top of the inner cavity of the housing 12 and located below the guide plate 15. Multiple falling channels 42 are evenly arranged on the conveyor belt 41. A baffle 43, made of ABS engineering plastic, is fixedly connected to the inner wall of the housing 12 at the left end of the inner side of the conveyor belt 41. This baffle 43 is lightweight and impact-resistant, preventing soybean particles from getting caught between the conveyor belt 41 and the rotating roller, ensuring that all soybean particles are effectively collected. An upper guide hopper 44, fixedly connected to the inner wall of the housing 12, is located below the conveyor belt 41. The bottom outlet is fixedly connected to a lower guide hopper 45 that fits against the left side of the crushing hopper 31. Both the lower guide hopper 45 and the upper guide hopper 44 are made of 304 stainless steel, ensuring smooth guidance and eliminating dead corners where bean particles may remain. A fan 46 is fixedly nested on the left side of the lower guide hopper 45, and a separation channel 47 is opened on the right side of the lower guide hopper 45. An output pipe A48 is fixedly connected to the bottom outlet of the lower guide hopper 45, and an infrared counter 49 is fixedly installed at the bottom outer side of the output pipe A48. The conveyor belt 41, the fan 46, and the infrared counter 49 are all electrically connected to the PLC controller inside the control cabinet 16.

[0030] By setting up the above structure, after the soybean grains roll onto the top of the conveyor belt 41, they fall into the upper guide hopper 44 through the falling channel 42. After the soybean stalks fall onto the top of the conveyor belt 41, they are continuously conveyed to the right by the conveyor belt 41 and finally fall into the crushing hopper 31 through the top opening of the crushing hopper 31. The soybean grains falling into the upper guide hopper 44 are guided into the lower guide hopper 45, and then fall into the output pipe A48 through the lower guide hopper 45. Finally, they are output to the right side of the inner side of the bearing plate 62 through the bottom opening of the output pipe A48. During this process, the fan 46 blows air on the falling soybean grains, so that the small amount of debris contained in the soybean grains passes through the separation channel 47 and falls into the crushing hopper 31 and is discharged synchronously. The infrared counter 49 counts the soybean grains when they are output from the output pipe A48 and sends a counting signal to the PLC controller inside the control cabinet 16. The PLC controller displays the number of soybean grains on the display 17.

[0031] like Figure 6 As shown, the phenotypic data acquisition component 5 includes a top plate 51 fixedly installed at the bottom left side of the lower guide hopper 45. A CCD camera 52 and two supplementary lights 53 are fixedly installed at the bottom of the top plate 51. The CCD camera 52 and the two supplementary lights 53 are electrically connected to the PLC controller inside the control cabinet 16. The CCD camera 52 is located directly above multiple carrier plates 62. The CCD camera 52 has high resolution and, together with the supplementary lights 53, provides uniform illumination, which can clearly capture the phenotypic characteristics of soybean particles such as size, shape, and color without shadow interference.

[0032] By setting up the above structure, the CCD camera 52 can take multiple pictures of the soybean particles inside the multiple receiving channels 621 as the soybean particles slowly roll inside the receiving channels 621, and at the same time transmit the captured data to an external computer, thereby achieving more comprehensive phenotypic data acquisition.

[0033] like Figure 7 As shown, the soybean particle distribution component 6 includes a fixed frame 61 fixedly mounted on the top of the base 11. A support plate 62 is fixedly mounted on the top of the fixed frame 61. Multiple receiving channels 621 are evenly opened on the inner side of the support plate 62. A movable plate 622 is slidably attached to the right end of the inner side of the support plate 62. Elastic connectors 623 are fixedly connected to both ends of the left side of the movable plate 622. The elastic connectors 623 are springs. A spreading plate 624, which is slidably attached to the inner side of the support plate 62, is fixedly connected to the left ends of the two elastic connectors 623. A support plate 63 is slidably attached to the bottom of the support plate 62. A rubber pad is nested on the top of the support plate 63. The rubber pad increases the friction between the support plate 63 and the soybean particles, so that when the support plate 63 moves the rubber pad to the right, the rubber pad can cause the soybean particles to rotate inside the receiving channels 621, thereby achieving more comprehensive phenotypic data. The collection system includes a connecting block 631 fixedly connected to the left side of the front of the tray 63, a guide bucket C632 fixedly connected to the bottom of the bearing plate 62 below the tray 63, an output pipe B633 extending to the outside of the housing 12 fixedly connected to the bottom opening of the guide bucket C632, an upper reciprocating screw 64 and a lower reciprocating screw 65 nested together on the inner front end of the fixing frame 61 via bearings, a motor C66 fixedly connected to the right side of the fixing frame 61 and driven by the upper reciprocating screw 64, the motor C66 being electrically connected to the PLC controller inside the control cabinet 16, an upper gear 67 nested together on the outer side of the upper reciprocating screw 64 in the horizontal direction, the upper gear 67 being rotatably set on the left front end of the moving plate 622 via bearings, a connecting block 631 being drivenly sleeved on the outer side of the lower reciprocating screw 65, and a lower gear 68 being fixedly sleeved on the left end of the outer side of the lower reciprocating screw 65.

[0034] By setting up the above structure, after all the soybean particles fall into the inner right end of the support plate 62, the motor C66 drives the upper reciprocating screw 64 to rotate continuously. When the upper reciprocating screw 64 rotates, it drives the moving plate 622, which is guided by the inner wall of the support plate 62, to move continuously to the left. The moving plate 622, through two elastic connectors 623, drives the spreading plate 624 to move continuously to the left. During the leftward movement of the spreading plate 624, it pushes the soybean particles stacked on the inner right end of the support plate 62, so that the large particles enter the multiple receiving channels 621 respectively. At this time, the bottom of the receiving channel 621 The opening is blocked by the support plate 63, preventing it from falling directly into the receiving channel 621. When the upper reciprocating screw 64 rotates, it drives the upper gear 67 to rotate synchronously through the outer groove and the inner slider of the upper gear 67. When the moving plate 622 moves to the left, it pushes the upper gear 67 to move to the left synchronously. When the moving plate 622 moves to the inner left end of the bearing plate 62, the left side of the paving plate 624 is in contact with the inner wall of the bearing plate 62 and blocked by the bearing plate 62. As the moving plate 622 continues to move to the left, the two elastic connecting pieces 623 are compressed. As the moving plate 622 continues to move to the left, the continuous rotation... The upper gear 67, driven by the moving plate 622, meshes with the lower gear 68, causing the lower gear 68 to rotate synchronously. The rotation of the lower gear 68 drives the lower reciprocating screw 65 to rotate synchronously. The rotation of the lower reciprocating screw 65, in turn, drives the support plate 63 to continuously move to the right via the connecting block 631. During this rightward movement, the soybean grains slowly roll inside the receiving channel 621. As the lower reciprocating screw 65 continues to rotate, the connecting block 631 moves to the rightmost end of the reciprocating thread on the outer side of the lower reciprocating screw 65. At this point, the lower part of the multiple receiving channels 621 is no longer obstructed. As soybean granules fall into the guide hopper C632 and are output through the output pipe B633, the connecting block 631 moves to the rightmost end of the reciprocating thread on the outer side of the lower reciprocating screw 65. As the lower reciprocating screw 65 continues to rotate, the connecting block 631 moves to the left to reset. During the leftward reset of the connecting block 631, the moving plate 622 moves to the leftmost end of the reciprocating thread on the outer side of the upper reciprocating screw 64 and drives the moving plate 622 to move to the right to reset. During the reset of the moving plate 622, it pulls the upper gear 67 to move to the right synchronously to reset. After the moving plate 622 is reset, the motor C66 stops.

[0035] The working process of this invention is as follows: A single soybean plant is vertically placed into the threshing hopper 21 with its top opening. Two guide plates A22 guide the soybean plant during placement, ensuring that the plant accurately enters between two eccentric shafts 23. A motor A25 drives the two eccentric shafts 23 to rotate continuously via two gears A24. As the shafts rotate, they continuously strike the soybean plant, causing the soybean grains to be extracted from the pods. Subsequently, the soybean stalks and the extracted soybean grains fall onto the top of the guide plate 15 and are guided by the guide plate 15 to the conveyor belt 41. After the soybean grains roll onto the top of the conveyor belt 41, they fall into the upper guide bucket 44 through the falling channel 42. After the soybean stalks fall onto the top of the conveyor belt 41, they are continuously conveyed to the right by the conveyor belt 41 and finally fall into the crushing bucket 31 through the top opening of the crushing bucket 31. At this time, the motor B35 drives the two crushing rollers 33 to rotate continuously through the two gears B34, thereby crushing the soybean stalks. The crushed soybean stalk fragments are output through the guide plate B32. Soybean particles falling into the upper guide hopper 44 are guided into the lower guide hopper 45, and then fall into the output pipe A48 from the lower guide hopper 45. Finally, they are output to the right side of the inner side of the bearing plate 62 through the bottom opening of the output pipe A48. During this process, the fan 46 blows air on the falling soybean particles, causing a small amount of debris contained in the soybean particles to pass through the separation channel 47 and fall into the crushing hopper 31 and be discharged synchronously. The infrared counter 49 counts the soybean particles when they are output from the output pipe A48 and sends a counting signal to the PLC controller inside the control cabinet 16. The PLC controller displays the number of soybean particles on the display 17. After all the soybean grains fall into the inner right end of the bearing plate 62, the motor C66 drives the upper reciprocating screw 64 to rotate continuously. When the upper reciprocating screw 64 rotates, it drives the moving plate 622, which is guided by the inner wall of the bearing plate 62, to move continuously to the left. The moving plate 622 drives the spreading plate 624 to move continuously to the left through the two elastic connectors 623. During the leftward movement of the spreading plate 624, it pushes the soybean grains stacked on the inner right end of the bearing plate 62, so that the large grains enter the multiple receiving channels 621 respectively. At this time, the bottom opening of the receiving channel 621 is blocked by the support plate 63, and cannot fall directly from the receiving channel 621. When the upper reciprocating screw 64 rotates, it drives the upper gear 67 to rotate synchronously through the sliding groove on its outer side and the slider on the inner side of the upper gear 67. When the moving plate 622 moves to the left, it pushes the upper gear 67 to move to the left synchronously. When the moving plate 622 moves to the left end of the inner side of the bearing plate 62, the left side of the paving plate 624 is attached to the inner wall of the bearing plate 62 and blocked by the bearing plate 62. When the moving plate 622 continues to move to the left, the two elastic connecting pieces 623 are compressed. As the moving plate 622 continues to move to the left, the continuously rotating upper gear 67 meshes with the lower gear 68 due to the push of the moving plate 622, causing the lower gear 68 to rotate synchronously. When the lower gear 68 rotates, it drives the lower reciprocating screw 65 to rotate synchronously. When the lower reciprocating screw 65 rotates, it drives the tray 63 to move continuously to the right through the connecting block 631. During the rightward movement of the tray 63, the soybean particles slowly roll inside the receiving channel 621. During this process, the CCD camera 52 takes multiple pictures of the soybean particles inside the multiple receiving channels 621 and transmits the captured data to the PLC controller, which then transmits it to the external computer. As the lower reciprocating screw 65 rotates continuously, the connecting block 631 moves to the rightmost end of the reciprocating thread on the outer side of the lower reciprocating screw 65. At this time, the lower part of the multiple receiving channels 621 is no longer blocked. As the soybean particles fall into the guide bucket C632 and are output through the output pipe B633, the output soybean particles fall into the soybean particle receiving cup 14. Then, the electronic weighing device 13 weighs the soybean particles in the soybean particle receiving cup 14 and sends the weighing data to the PLC controller inside the control cabinet 16. The PLC controller then displays the weight of the soybean particles on the display 17. After the connecting block 631 moves to the rightmost end of the reciprocating thread on the outer side of the lower reciprocating screw 65, as the lower reciprocating screw 65 continues to rotate, the connecting block 631 moves to the left to reset. During the leftward reset of the connecting block 631, the moving plate 622 moves to the leftmost end of the reciprocating thread on the outer side of the upper reciprocating screw 64 and drives the moving plate 622 to move to the right to reset. During the reset of the moving plate 622, it pulls the upper gear 67 to move to the right synchronously to reset until the moving plate 622 is reset, and then the motor C66 stops.

[0036] Finally, it should be noted that the above description is only a preferred embodiment of the present invention and is not intended to limit the present invention. Although the present invention 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. Any modifications, equivalent substitutions, improvements, etc., made within the spirit and principles of the present invention should be included within the protection scope of the present invention.
