Description

Technical Field

[0001] This invention belongs to the field of agricultural machinery technology, and particularly relates to a cleaning device for a rice transplanter and the rice transplanter itself. Background Technology

[0002] Rice, as an important crop, typically requires seedling cultivation during its production process. Once rice seeds have matured into seedlings, those with high survival rates are transplanted to ensure high yields. Traditional manual rice transplanting is inefficient, labor-intensive, and results in uneven seedling distribution, affecting light and ventilation and reducing yield. Rice transplanters, on the other hand, damage seedling roots during transplanting, prolonging the recovery period. Rice transplanters overcome the drawbacks of both manual and machine methods, offering high efficiency, no root damage, no recovery period, and high yields.

[0003] During the transplanting process using a rice transplanter, the machine uses a unique seedling-grasping mechanism to remove the seedlings from the seedling trays, their roots still covered in moist soil. The seedlings are then systematically thrown into the paddy field. This soil, mixed with broken seedling leaves, easily accumulates on the seedling-grasping mechanism, such as the seedling clamps, clamping belts, and other auxiliary structures. This accumulated soil can clog the mechanism, leading to failed seedling removal and hindering the transplanter's smooth operation. Currently, the soil is typically washed manually from the seedling-grasping mechanism. However, when this problem occurs, transplanting must be stopped, and the transplanter must be driven to a clean water source for cleaning, causing significant inconvenience, increasing labor costs, and wasting valuable time. Summary of the Invention

[0004] In view of the above-mentioned defects or deficiencies of the prior art, the present invention provides a cleaning device and a rice transplanter for a rice transplanter, aiming to solve the technical problem that the existing washing method of the rice transplanter's seedling picking mechanism causes great inconvenience to users, increases labor burden and wastes valuable working time.

[0005] To achieve the above objectives, the present invention provides a cleaning device for a rice transplanter, comprising a water tank, a water pipe assembly, a nozzle, a water pump, and a camera; the water tank is disposed at the head of the rice transplanter; the water pipe assembly is connected to the water tank and extends along the chassis of the rice transplanter from the head toward the seedling-collecting mechanism at the tail of the rice transplanter; the nozzle is connected to the end of the water pipe assembly and is disposed toward the seedling-collecting mechanism; the water pump is mounted on the water pipe assembly; and the camera is disposed above the seedling-feeding section of the rice transplanter to control the water pump to start based on the seedling-feeding images captured by the camera.

[0006] In this embodiment of the invention, the cleaning device further includes a three-way connector and a water gun assembly. The first and second connectors of the three-way connector are connected to a water pipe assembly located between the water pump and the nozzle. The water gun assembly is connected to the third connector of the three-way connector.

[0007] In this embodiment of the invention, the water gun assembly includes a first on / off valve that is connected to a third connector via a connecting water pipe, an extended water pipe that is detachably connected to the first on / off valve, and an adjustable pressure water gun connected to the end of the extended water pipe away from the first on / off valve.

[0008] In this embodiment of the invention, a high-pressure fan-shaped nozzle is provided on the nozzle head.

[0009] In an embodiment of the present invention, the water tank includes a tank body with a water outlet and a first water purification module located inside the tank body, and a water pipe assembly extends from the water outlet into the tank body and is connected to the first water purification module.

[0010] In this embodiment of the invention, the first water purification module includes a first mounting base with an installation hole, a filter screen disposed on one side of the first mounting base around the installation hole, and a first filter cloth wrapped around the outside of the filter screen. One end of the water pipe assembly extends into the body of the box and enters the water purification chamber formed by the filter screen through the installation hole.

[0011] In this embodiment of the invention, the cleaning device further includes a controller mounted on the machine head. The controller is communicatively connected to both a camera and a water pump. The controller is configured to:

[0012] Get images of seedlings being planted;

[0013] Determine whether seedling blockage has occurred based on the photos of seedlings being introduced;

[0014] If seedling blockage occurs within the preset blocking time, the water pump will be turned on.

[0015] In this embodiment of the invention, determining whether seedling blockage has occurred based on the seedling entry image includes:

[0016] Input the seedling images into the image recognition model;

[0017] The image recognition model determines whether seedling blockage has occurred.

[0018] In this embodiment of the invention, the controller is further configured to:

[0019] Obtain automatic operation instructions, preset start time, and preset stop time;

[0020] The water pump is controlled to start and stop at preset start and stop times according to automatic operation instructions.

[0021] In this embodiment of the invention, the controller is further configured to:

[0022] Obtain manual operation instructions;

[0023] The water pump is turned on and off according to manual operation instructions.

[0024] In this embodiment of the invention, the controller is further configured to:

[0025] Determine whether there is any abnormal water spraying based on the photos of the seedlings being introduced;

[0026] The controller outputs a command to start the water pump as a prerequisite. If an abnormal water spraying occurs, the controller will control the water pump to run alternately in the forward and reverse directions.

[0027] To achieve the above objectives, the present invention also provides a rice transplanter, wherein the rice transplanter includes a cleaning device for the rice transplanter as described above.

[0028] Through the above technical solution, the cleaning device for rice transplanters provided in this embodiment of the invention has the following beneficial effects:

[0029] The cleaning device for a rice transplanter includes a water tank, a water pipe assembly, a spray nozzle, a water pump, and a camera. The water tank is installed at the head of the transplanter. The water pipe assembly is connected to the water tank and extends along the chassis of the transplanter from the head towards the seedling-collecting mechanism at the tail. The spray nozzle is connected to the end of the water pipe assembly and faces the seedling-collecting mechanism. The water pump is installed on the water pipe assembly. The camera is positioned above the seedling-feeding section of the transplanter to control the water pump's operation based on images captured by the camera. The transplanting method can be determined based on the images captured by the camera. If the seedling inlet of the machine is blocked, it means that the accumulated mud in the seedling picking mechanism is preventing the seedlings from passing through. If the blockage is confirmed by the seedling inlet image, the water pump can be turned on to guide the water in the water tank through the water pipe assembly to the nozzle to clean the accumulated mud on the seedling picking mechanism. This eliminates the need to stop the seedling throwing operation or move the seedling thrower to a place with clean water for manual cleaning. This achieves automatic cleaning of the seedling picking mechanism, improving ease of use, reducing labor burden, and reducing operation time.

[0050] The specific embodiments of the present invention will be described in detail below with reference to the accompanying drawings. It should be understood that the specific embodiments described herein are for illustration and explanation only and are not intended to limit the present invention.

[0051] The cleaning apparatus for a rice transplanter according to the present invention is described below with reference to the accompanying drawings.

[0052] like Figure 1 As shown, the present invention provides a cleaning device for a rice transplanter, wherein the cleaning device for the rice transplanter includes:

[0053] Water tank 3 is used to be installed at the head 1 of the rice transplanter;

[0054] Water pipe assembly 4 is connected to water tank 3 and is provided to extend along the chassis of rice transplanter from the head 1 toward the tail 2 of rice transplanter for the seedling taking mechanism.

[0055] The nozzle 5 is connected to the end of the water pipe assembly 4 and is positioned toward the seedling picking mechanism;

[0056] Water pump 6 is installed on water pipe assembly 4; and

[0057] A camera 211 is installed above the seedling inlet section 21 of the rice transplanter so that the water pump 6 can be turned on based on the seedling inlet image captured by the camera 211.

[0058] Using the aforementioned cleaning device in the rice transplanter, the presence of a seedling inlet 21 can be determined based on the seedling inlet image captured by camera 211. If the seedling inlet 21 is blocked, it indicates that the accumulated mud in the seedling collection mechanism has prevented the seedlings from passing through. When the seedling inlet 21 is blocked based on the seedling inlet image, the water pump 6 can be turned on to guide the water in the water tank 3 through the water pipe assembly 4 to the nozzle 5 to clean the accumulated mud on the seedling collection mechanism. This eliminates the need to stop the rice transplanting operation or move the rice transplanter to a place with a clean water source for manual cleaning, thus achieving automatic cleaning of the seedling collection mechanism. This improves ease of use, reduces labor burden, and shortens operation time.

[0059] Specifically, during the operation of the rice transplanter, the user places the seedling tray filled with seedlings onto the belt of the seedling inlet section 21 of the transplanter. Under normal circumstances, the seedling tray can smoothly reach the seedling picking mechanism, which can pick up the seedlings with soil attached to their roots from the seedling tray and send them to the transplanting section for transplanting. In abnormal circumstances, that is, the soil attached to the roots of the seedlings will block the seedling picking mechanism, causing the number of seedlings that cannot pass through the seedling picking mechanism to gradually increase, forming a blockage. Therefore, a camera 211 is installed above the seedling inlet section 21 to automatically determine whether a blockage has occurred by taking pictures of the seedlings entering the machine. If a blockage occurs, the water pump 6 can be activated to clean the accumulated mud on the seedling picking mechanism. In this invention, the camera 211 is positioned above the seedling inlet 21. The acquired images of the seedling inlet 21 are used to determine whether the seedling inlet 21 is blocked. Based on the blockage, it is determined whether the accumulated mud on the seedling removal mechanism has blocked the mechanism, preventing the seedlings from passing through. This is not done by directly positioning the camera 211 near the seedling removal mechanism to acquire images containing the mechanism and directly determining whether the accumulated mud on the mechanism has blocked it. This is because the space within the seedling removal mechanism is very narrow, making it difficult to install the camera 211 and acquire images. Furthermore, the large amount of accumulated mud within the mechanism can easily damage the camera 211. Positioning the camera 211 above the seedling inlet 21 undoubtedly facilitates the installation of the camera 211 and the acquisition of images, while also extending the service life of the camera 211.

[0060] See Figure 1 and Figure 2 In this embodiment of the invention, the cleaning device further includes a three-way connector 7 and a water gun assembly 8. The first connector 71 and the second connector 72 of the three-way connector 7 are connected to the water pipe assembly 4 located between the water pump 6 and the nozzle 5. The water gun assembly 8 is connected to the third connector 73 of the three-way connector 7. Specifically, the water pipe assembly 4 includes a first water pipe 41 disposed between the water tank 3 and the input end of the water pump 6, a second water pipe 42 disposed between the water pump 6 and the first connector 71 of the three-way connector 7, and a third water pipe 43 disposed between the second connector 72 of the three-way connector 7 and the nozzle 5. Since the water gun assembly 8 is connected to the third connector 73 of the three-way connector 7, the cleaning device can also wash away the accumulated mud on the rice transplanter through the water gun assembly 8, thereby facilitating the maintenance of the entire vehicle.

[0061] In this embodiment of the invention, the water gun assembly 8 includes a first on / off valve 81 connected to a third connector 73 via a connecting water pipe 44, an extended water pipe 82 detachably connected to the first on / off valve 81, and an adjustable pressure water gun 83 connected to the end of the extended water pipe 82 away from the first on / off valve 81. That is, by controlling the opening or closing of the first on / off valve 81, the adjustable pressure water gun 83 can be controlled to perform a full-machine cleaning operation on the rice transplanter. The extended water pipe 82 is detachably connected to the first on / off valve 81, thus facilitating the removal and proper storage of the extended water pipe 82 from the first on / off valve 81 when a full-machine cleaning operation is not required. In addition, the first shut-off valve 81 can also have an air venting function. When the water in the water tank 3 is used up, air will be drawn into the water pipe assembly 4. When the water in the water tank 3 is replenished, the air in the water pipe assembly 4 cannot be expelled in time, resulting in an air blockage. This causes the water pump 6 to be unable to pump water from the water tank 3 to the nozzle 5. At this time, the first shut-off valve 81 connected to the third connector 73 can be opened, and the water pump 6 can be turned on without connecting the extension water pipe 82. This allows the water pump 6 in the water tank 3 to be smoothly inserted into the water pipe assembly 4, and the air can be expelled from the first shut-off valve 81, thus completing the air venting operation.

[0062] Specifically, the first shut-off valve 81 can be a quick-connect valve, facilitating installation on the connecting water pipe 44. When the water gun assembly 8 is needed to clean the entire rice transplanter, the first shut-off valve 81 can be opened; otherwise, it can remain closed. It should be noted that a second shut-off valve 9 can also be provided between the nozzle 5 and the three-way connector 7. That is, when the first shut-off valve 81 is open for cleaning the entire machine, the second shut-off valve 9 can remain closed, while it can be opened when cleaning the seedling-taking mechanism. Of course, the invention is not limited to this; the three-way connector 7 can also be a three-way valve housing structure, meaning that a reversing valve core is provided inside the three-way connector 7 to control the water in the water tank 3 to guide the nozzle 5 and / or the water gun assembly 8.

[0063] In this embodiment of the invention, the nozzle 5 may be equipped with a high-pressure fan-shaped nozzle. The high-pressure fan-shaped nozzle is hollow inside, without any other complex structure, making it less prone to mud accumulation and thus providing an anti-clogging function. Furthermore, the nozzle forms a small rectangular opening, resulting in a fan-shaped spray effect with wide coverage, saving water, reducing the frequency of water replenishment in the water tank 3, and alleviating labor burden. Specifically, there are multiple high-pressure fan-shaped nozzles, spaced apart on the nozzle 5. The specific number of high-pressure fan-shaped nozzles can be determined based on the number of seedling-collecting mechanisms on the rice transplanter.

[0064] See Figure 1 and Figure 3In this embodiment of the invention, the water tank 3 includes a tank body 31 with a water outlet and a first water purification module 32 located inside the tank body 31. The water pipe assembly 4 extends from the water outlet into the tank body 31 and connects to the first water purification module 32. That is, the first water purification module 32 can purify the water entering the water pipe assembly 4 from the water tank 3, allowing users to draw water locally near fields (e.g., ditches, rivers, etc.) without encountering blockages in the water pipe assembly 4 or the sprinkler head 5 due to water quality issues. This makes the invention more adaptable to agricultural environments, reduces water quality requirements, and saves labor costs.

[0065] In this embodiment of the invention, the first water purification module 32 includes a first mounting base 321 with a mounting hole, a filter screen 322 disposed on one side of the first mounting base 321 around the mounting hole, and a first filter cloth wrapped around the outside of the filter screen 322. One end of the water pipe assembly 4 extends into the tank body 31 and enters the water purification chamber formed by the filter screen 322 through the mounting hole. That is, when the water pump 6 is turned on to pump water from the water tank 3 to the nozzle 5, the water in the water tank 3 first passes through the first filter cloth for a first filtration, and then through the filter screen 322 for a second filtration before entering the water purification chamber and flowing into the water pipe assembly 4. Thus, the first water purification module 32, composed of the first filter cloth and the filter screen 322, achieves a secondary filtration effect to improve the cleanliness of the water. Even if the first filter cloth is broken, the filter screen 322 can still perform the filtration function. Specifically, the filter screen 322 can be made of stainless steel.

[0066] In this embodiment of the invention, the tank body 31 is also provided with a water inlet, and the water tank 3 further includes a second water purification module 33 corresponding to the water inlet disposed on the tank body 31, that is, when water is added to the water tank 3, it can be purified first through the second water purification module 33. Further, the second water purification module 33 may include a second filter cloth.

[0067] In this embodiment of the invention, a quick-connect fitting 45 is fitted onto one end of the water pipe assembly 4 near the water tank 3. The quick-connect fitting 45 is inserted into the tank body 31 from the water outlet and fixed to the tank body 31. By pressing the O-ring of the quick-connect fitting 45, the water pipe assembly 4 can be freely and quickly removed from the water tank 3. In addition, a first mounting bracket 11 is provided on the chassis corresponding to the head 1 of the rice transplanter. The water tank 3 can be fixed to the first mounting bracket 11 by metal bands and bolts. Rubber blocks are placed between the water tank 3 and the metal bands, and between the water tank 3 and the first mounting bracket 11. The rubber blocks can be used to absorb the vibration generated by the chassis and also prevent the water tank 3 from being worn through by the metal bands. More specifically, the water pipe assembly 4 is laid along the chassis frame of the rice transplanter, and the water pipe assembly 4 is fixed with cable ties or metal buckles every 300mm at the corners; the four support feet of the water pump 6 can be made of rubber to eliminate the vibration generated by the water pump 6 itself and the vibration caused by the operation of the chassis engine. The four support feet of the water pump 6 are fixed to the second mounting bracket with bolts, and the second mounting bracket is fixed to the chassis; the three-way connector 7 is fixed by compression nuts to connect the second water pipe 42, the third water pipe 43 and the connecting water pipe 44 from three directions.

[0068] In this embodiment of the invention, the cleaning device further includes a controller mounted on the machine head 1. The controller is communicatively connected to the camera 211 and the water pump, and is configured to:

[0069] Get images of seedlings being planted;

[0070] Determine whether seedling blockage has occurred based on the photos of seedlings being introduced;

[0071] If seedling blockage occurs within the preset blocking time, then control water pump 6 to start.

[0072] Specifically, camera 211 sends the captured images of the seedlings entering the plant to the controller. The controller determines whether seedling blockage has occurred based on the images. If blockage occurs and persists for a preset time, the controller activates water pump 6 to enable the cleaning device to enter intelligent cleaning mode, thereby clearing the accumulated mud from the seedling-collecting mechanism and resolving the blockage. More specifically, after initially determining that blockage has occurred based on the seedling images, the controller continues to acquire images of the seedlings entering the plant within the preset time. If the acquired images still indicate blockage, the controller activates water pump 6 to prevent erroneous operation. Furthermore, the controller can also be equipped with a control button to start and stop camera 211.

[0073] In this embodiment of the invention, if seedling blockage occurs within the preset blocking time, after controlling the water pump 6 to start, the method further includes: continuing to acquire seedling entry images captured by the camera 211; if the acquired seedling entry images are determined to indicate that no seedling blockage has occurred, the water pump 6 can be controlled to shut down.

[0074] In this embodiment of the invention, determining whether seedling blockage has occurred based on the seedling entry image includes:

[0075] Input the seedling images into the image recognition model;

[0076] The image recognition model determines whether seedling blockage has occurred.

[0077] Furthermore, the image recognition model can be obtained by training a RetNet50 classification model. Specifically, it can be trained using images of the seedling entry section 21 idling, the seedling entry section 21 normally entering seedlings, and the seedling entry section 21 abnormally entering seedlings (i.e., seedling blockage). If the image recognition model outputs "0", it indicates that the input image is an image of the seedling entry section 21 idling; if the image recognition model outputs "1", it indicates that the input image is an image of the seedling entry section 21 normally entering seedlings; and if the image recognition model outputs "2", it indicates that the input image is an image of the seedling entry section 21 abnormally entering seedlings. After inputting the seedling entry images captured by the camera 211 into the image recognition model, the image recognition model can identify whether seedling blockage has occurred based on the seedling entry images and output the recognition result. Of course, the present invention is not limited to this. The controller can also store images of the seedling inlet 21 idling, the seedling inlet 21 normally inleting seedlings, and the seedling inlet 21 abnormally inleting seedlings. By comparing the seedling inlet images captured by the camera 211 with the pre-stored images one by one, it is possible to determine whether the seedling inlet 21 has entered the seedling stage based on the degree of similarity.

[0078] In this embodiment of the invention, the controller is further configured to:

[0079] Obtain automatic operation instructions, preset start time, and preset stop time;

[0080] The water pump 6 is controlled to start and stop at preset start and stop times according to the automatic operation instructions.

[0081] Specifically, the automatic operation command can be issued via the "Automatic" button on the control panel located at the head 1 of the rice transplanter. When the user presses the "Automatic" button, an automatic operation command to start the water pump 6 is sent to the controller, putting the cleaning device into automatic cleaning mode. Simultaneously, the control panel at the head 1 also has an input device for setting preset start and stop times. When the cleaning device is in automatic cleaning mode, the controller can first control the water pump 6 to start for the preset start time, then control the water pump 6 to stop for the preset stop time, and then control the water pump 6 to start for the preset start time, repeating this process to achieve the automatic cleaning function of the cleaning device. This allows users to set preset start and stop times based on the degree of mud adhesion on the seedling-harvesting mechanism, achieving water conservation.

[0082] In this embodiment of the invention, the controller is further configured to:

[0083] Obtain manual operation instructions;

[0084] The water pump 6 is turned on and off according to the manual operation instructions.

[0085] In this embodiment of the invention, the manual operation command can be issued through the "manual" button on the control panel located at the head 1 of the rice transplanter. That is, when the user presses the "manual" button, a manual operation command to start the water pump 6 can be sent to the controller, so that the cleaning device is in manual cleaning mode. Furthermore, the control panel located at the head 1 of the rice transplanter can also be equipped with a "close" button. That is, when the user presses the "close" button, a manual operation command to close the water pump 6 can be sent to the controller.

[0086] In this embodiment of the invention, the controller is further configured to:

[0087] Determine whether there is any abnormal water spraying based on the photos of the seedlings being introduced;

[0088] The controller outputs the start of the water pump as a prerequisite. If an abnormal water spraying occurs, the controller will control the water pump 6 to run alternately in the forward and reverse directions.

[0089] Specifically, the camera 211 is positioned above the seedling inlet 21 of the rice transplanter, and the camera 211 can be a wide-angle camera 211. The shooting range can cover not only the seedling inlet position of the seedling inlet 21, but also the water spraying position of the nozzle 5. Therefore, the seedling inlet image acquired by the camera 211 includes the water spraying image of the nozzle 5. Thus, it is possible to determine whether a water spraying abnormality has occurred based on whether the nozzle 5 is spraying water in the seedling inlet image. If the nozzle 5 is not spraying water in the seedling inlet image, it is determined that a water spraying abnormality has occurred. A water spraying abnormality can prove that at least one of the first water purification module 32, water pipe assembly 5, or nozzle 5 is blocked. At this time, the controller enters the self-cleaning mode and controls the water pump 6 to rotate in both directions, so that the water flow can alternately flush between the first water purification module 32, water pipe assembly 4, and nozzle 5 in both forward and reverse directions, thereby realizing the self-cleaning function of the present invention, reducing the probability of blockage and achieving maintenance-free function. Specifically, the self-cleaning mode can control the water pump 6 to rotate forward for 5 seconds, then reverse for 5 seconds, and repeat this alternating operation for 2 minutes. This allows the water flow to alternate between the first water purification module 32, the water pipe assembly 4, and the nozzle 5, flushing away the accumulated mud on the inner wall of the water pipe, the outer wall of the filter screen 322, and the nozzle 5, thus achieving the self-cleaning function.

[0090] In addition, after the self-cleaning function is activated for the first time, it will not be activated again within the preset self-cleaning interval to avoid repetitive and unnecessary operations. The process continues until the preset self-cleaning interval reaches zero, at which point the acquired seedling entry images are used to determine if any abnormal water spraying has occurred, and the next cycle of checks begins.

[0091] In this embodiment of the invention, determining whether an abnormal water spraying has occurred based on the seedling entry image includes:

[0092] Input the seedling images into the image recognition model;

[0093] The image recognition model determines whether an abnormal water spraying has occurred based on its recognition results.

[0094] Furthermore, the image recognition model can be obtained by training a RetNet50 classification model. Specifically, it can be trained using images of the seedling entry section 21 idling, the seedling entry section 21 normally entering seedlings, the seedling entry section 21 abnormally entering seedlings (i.e., seedling blockage), and abnormal water spraying. If the image recognition model outputs "0", it indicates that the input image is an image of the seedling entry section 21 idling; if the image recognition model outputs "1", it indicates that the input image is an image of the seedling entry section 21 normally entering seedlings; if the image recognition model outputs "2", it indicates that the input image is an image of the seedling entry section 21 abnormally entering seedlings; and if the image recognition model outputs "3", it indicates that the input image is an image of abnormal water spraying. After inputting the seedling entry images captured by the camera 211 into the image recognition model, the image recognition model can identify whether seedling blockage or abnormal water spraying has occurred based on the seedling entry images and output the recognition results.
