Description

Technical Field

[0001] This utility model relates to the field of agricultural machinery technology, and in particular to a seeding device. Background Technology

[0002] Currently, most seeders equipped with hill-seeders employ a fully enclosed design. Therefore, relying solely on human vision and hearing makes it impossible to effectively monitor the quality of the hill-seeder's operation. This leads to potential risks during the sowing process. For example, the seed delivery tube may become clogged or miss seeds. Such malfunctions can potentially prevent the sowing of one or even several rows, resulting in severe missed seeds. Missed seeds directly reduce crop yields and cause economic losses for farmers.

[0003] To effectively address this issue and improve the quality of precision seeding, an electronic intelligent monitoring system is used to monitor the seeding process of the seeder in real time. This system can issue audible and visual alarms when it detects abnormalities, notifying the driver of any missed seeding failures. This allows the driver to take timely measures to resolve the problem, ensuring smooth seeding operations, minimizing the risk of missed seeding, and guaranteeing stable and efficient agricultural production.

[0004] As mentioned in the prior art publication CN105325102B, "A Duckbill Seed Meter Missed Seeding Inspection Device for a Film-Laying Seeder" is installed on the film-laying seeder for real-time monitoring and alarm of the duckbill seed metering device. The inspection device includes: a pressure sensor, a data acquisition module, and a wireless transmission module installed on the duckbill seed metering device; a data processing module and a display module installed on the film-laying seeder. Specifically, the pressure sensor is installed on the bottom surface of the seed discharge cavity of the duckbill seed metering device. When the seeds fall onto the sensor surface, they generate an impact force on the sensor. Through signal reception and processing, the frequency of seed falling is obtained. Combined with the walking speed of the seeder, real-time detection and alarm of missed seeding are realized.

[0005] However, the pressure sensors and other components mentioned above are all connected by wires. This not only requires additional wiring holes for the wires to pass through, but also the excessive number of wires may cause problems such as wire tangling and wire breakage due to external force during the operation of the film-laying seeder, resulting in data loss. Utility Model Content

[0006] The purpose of this invention is to provide a seeding device that solves the problem of wire breakage caused by connecting the monitor and receiver with wires, and achieves the effect of ensuring a stable electrical connection between the monitor and receiver without the need for wire connection.

[0007] To achieve the above objectives, this utility model adopts the following technical solution: a seeding device, comprising... The mounting plate assembly is equipped with a receiver. The rotating disk assembly, which rotates relative to the fixed disk assembly, includes an annular seed-collecting block assembly and a plurality of duckbill assemblies spaced apart along the outer periphery of the seed-collecting block assembly. The duckbill assemblies are equipped with a monitor for monitoring seeding. The receiver includes a receiver body and a first conductive element electrically connected to the receiver body. The seed-collecting block assembly is equipped with a second conductive element electrically connected to the monitor. The second conductive element makes electrical contact with or separates from the first conductive element as the rotating disk assembly rotates. The electrical contact between the second conductive element and the first conductive element electrically connects the receiver body and the monitor to form a monitoring circuit.

[0008] After adopting the above technical solution, this utility model has the following advantages: The first conductive element is disposed on the receiver located on the fixed plate assembly, and the second conductive element is disposed on the seed-collecting block assembly. The second conductive element can rotate with the rotation of the seed-collecting device assembly. When it rotates to contact the first conductive element, the monitor and the receiver are electrically connected; when it rotates to separate from the first conductive element, the electrical connection between the monitor and the receiver is broken. Therefore, the connection between the monitor and the receiver can be controlled by the working path of the moving plate assembly itself. This eliminates the need for additional wires to electrically connect the monitor and the receiver, simplifying the electrical connection method between the two. It also eliminates the need for wire holes, reducing the number of parts processing steps. At the same time, eliminating the wire connection also avoids problems such as wire breakage that may occur when the moving plate assembly rotates relative to the fixed plate assembly during the operation of the seeder, improving the stability and reliability of the connection between the monitor and the receiver.

[0009] Furthermore, the second conductive element has a fixed end fixed to the seed-taking block assembly and an elastic arm extending from the fixed end. When the second conductive element is in electrical contact with the first conductive element, the elastic arm remains in contact with the first conductive element.

[0010] Using the aforementioned technical solution, the second conductive element is fixed to the fixed end of the seed-collecting block assembly, preventing displacement or loosening during operation due to rotation of the moving disk assembly or other external forces. When the second conductive element makes electrical contact with the first conductive element, the elastic arm maintains contact with the first conductive element due to its own elasticity, avoiding poor contact. Even when the seeder experiences some shaking during operation, the elastic arm maintains good contact with the first conductive element, ensuring the stability of the electrical connection between the monitor and the receiver. Furthermore, the elastic arm of the second conductive element has the ability to deform elastically. During the rotation of the moving disk assembly, when the second and first conductive elements rotate relative to each other, the elastic arm can buffer the impact through elastic deformation, reducing rigid collisions and friction between them. This not only reduces wear on both the first and second conductive elements, extending their service life, but also ensures good contact between them during long-term use, guaranteeing the normal operation of the monitoring circuit.

[0011] Furthermore, the elastic arm is a protruding structure formed by bending the first metal part itself, and the vertical distance h1 from the protruding structure to the fixed end extension surface is greater than the vertical distance h2 from the first conductive part to the fixed end extension surface.

[0012] By adopting the aforementioned technical solution, during the rotation of the moving disk assembly, when the elastic arm gradually approaches the first conductive element, since h1 > h2, the elastic arm will undergo elastic deformation during the contact process with the first conductive element, which can ensure that the elastic arm and the first conductive element always maintain a tight contact state. Even if there are factors such as vibration during the operation of the seeder, the elastic arm has sufficient elastic deformation to maintain good contact with the first conductive element, thus ensuring the reliability of the electrical connection between the monitor and the receiver.

[0013] Furthermore, the elastic arm has a first inclined surface, and the first conductive element has a second inclined surface. When the second conductive element rotates to make electrical contact with the first conductive element, the first inclined surface slides along the second inclined surface, guiding the elastic arm to undergo elastic deformation, so that the second conductive element contacts the first conductive element.

[0014] Using the aforementioned technical solution, when the second conductive component rotates to make electrical contact with the first conductive component, the first inclined surface slides along the second inclined surface. This makes the contact between the second and first conductive components a gradual process. As the first inclined surface slides along the second inclined surface, the elastic arm gradually deforms elastically, and the contact force between the two gradually increases. This reduces the impact of the contact between the first and second conductive components, reduces damage to the conductive parts caused by impact, and extends the service life of both the first and second conductive components. Furthermore, during the long-term operation of the seeder, this gentle contact method effectively avoids the problem of loosening or damage to the first and second conductive components due to repeated impacts.

[0015] Furthermore, the duckbill assembly contains an insulated seed guide, and the monitor is located within the seed guide.

[0016] Furthermore, a first channel for seeds to fall into is formed within the seed guide, and the monitoring end of the monitor is placed within the first channel.

[0017] Using the aforementioned technical solution, during the sowing process, the seeds pass through the first channel, and the monitoring end of the monitor can monitor information such as the time and quantity of the seeds passing through, thereby judging the passage of the seeds. Once an abnormality is detected, the monitor can send a signal in time and take corresponding measures, which improves the reliability of the hill seeder.

[0018] Furthermore, the monitoring module is a photoelectric sensor. Attached Figure Description

[0022] The technical solution of this utility model will be described in detail below with specific embodiments. The following specific embodiments can be selected to be combined or substituted with each other according to the actual situation, and the same or similar concepts or processes may not be described again in some embodiments.

[0023] like Figures 1 to 3 As shown, a seeding device includes... The fixed plate assembly 100 is equipped with a receiver 110; The moving disk assembly, which rotates relative to the fixed disk assembly 100, includes an annular seed-collecting block assembly 300 and a plurality of duckbill assemblies 200 spaced apart along the outer periphery of the seed-collecting block assembly 300. The duckbill assembly 200 is provided with a monitor 210 for monitoring sowing. The receiver 110 includes a receiver body 111 and a first conductive element 112 electrically connected to the receiver body 111. The seed-collecting block assembly 300 is provided with a second conductive element 310 electrically connected to the monitor 210. The second conductive element 310 comes into electrical contact with or separates from the first conductive element 112 as the moving disk assembly rotates. The electrical contact between the second conductive element 310 and the first conductive element 112 electrically connects the receiver body 111 and the monitor 210 to form a monitoring circuit.

[0024] Understandably, the first conductive element 112 is located on the receiver 110 of the fixed plate assembly 100, and the second conductive element 310 is located on the seed-collecting block assembly 300. The second conductive element 310 can rotate with the rotation of the seed-collecting assembly. When it rotates to contact the first conductive element 112, the monitor 210 and the receiver 110 are electrically connected. When it rotates to separate from the first conductive element 112, the electrical connection between the monitor 210 and the receiver 110 is broken. Therefore, the connection between the monitor 210 and the receiver 110 can be controlled by the working path of the moving plate assembly itself. This eliminates the need for additional wires to electrically connect the monitor 210 and the receiver 110, simplifying the electrical connection method and eliminating the need for wire holes, thus reducing the number of parts processing steps. Furthermore, eliminating the wire connection avoids potential wire breakage during the rotation of the moving plate assembly relative to the fixed plate assembly 100 when the seeder is working, improving the stability and reliability of the connection between the monitor 210 and the receiver 110.

[0025] It should be noted that this embodiment uses a socket-type seeding device as an example, but in actual use it can also be applied to disc-type seeding devices, finger-clamp seeding devices, and toothed disc seeding devices, etc.

[0026] Specifically, such as Figure 1 As shown, the seeder is divided into a seed filling state and a seed discharging state. Seeds are only discharged under gravity when the duckbill assembly 200 rotates to the seed discharging state.

[0027] Seeds are placed in the seed-collecting block assembly 300 and sown into the farmland by the duckbill assembly 200. In this embodiment, fifteen duckbill assemblies 200 are arranged at intervals along the circumference of the seed-collecting block assembly 300. The fifteen duckbill assemblies 200 rotate with the rotation of the moving plate assembly. Therefore, all fifteen duckbill assemblies 200 are in the sowing state.

[0028] In addition, such as Figures 4 to 7 As shown, the duckbill assembly 200 includes a movable duckbill and a fixed duckbill 220. Each duckbill assembly 200 contains an insulated seed guide 230, which is located within the fixed duckbill 220. The seed guide 230 is manufactured using 3D printing, and a monitor 210 is located within the seed guide 230. A first channel 240 for seeds to fall into the seed guide 230 is formed within the seed guide 230, and the monitoring end 211 of the monitor 210 is placed within the first channel 240. Thus, during sowing, as seeds pass through the first channel 240, the monitoring end 211 of the monitor 210 can monitor information such as the time and quantity of seeds passing through, thereby determining the seed passage status. Once an abnormality is detected, the monitor 210 can promptly send a signal and take corresponding measures, improving the reliability of the seed planter.

[0029] Specifically, the monitor 210 has a "U" shaped structure, allowing the seed to fall through the notch in the monitor 210.

[0030] Preferably, the monitoring module is a photoelectric sensor. When a seed falls from the first channel 240, it briefly blocks the monitor 210 to identify the seed's fall, and then transmits the detected signal to the receiver 110.

[0031] It should be explained that the seeds will only fall through the first channel 240 in the seed guide 230 when the duckbill assembly 200 is in the sowing state, because when monitoring the sowing status of the seeds, it is only necessary to monitor the sowing status of the duckbill assembly 200.

[0032] For example, if each duckbill assembly 200 is set to drop one seed in the sowing state, and there are four duckbill assemblies 200 in the sowing state, then the monitors 210 of these four duckbill assemblies 200 should all detect that one seed has fallen. If any duckbill assembly 200 fails to detect the seed falling, then the receiver 110 will receive the signal of the duckbill assembly 200 that missed the sowing.

[0033] In detail, the receiver 110 includes a receiver body 111 and a first conductive element 112 electrically connected to the receiver body by a metal bolt, wherein the power supply for the monitor 210 is also integrated into the receiver 110.

[0034] The seed extractor assembly is also provided with a second conductive element 310 that is electrically connected to the monitor 210.

[0035] It should be noted that the seed collection block assembly 300 includes seed holes for seed dispensing. In order to ensure that only a specified number of seeds can pass through the seed hole through the duckbill assembly 200, a curtain is provided at the seed hole position. In order to ensure that the curtain can be stably installed on the seed collector assembly, the curtain is fixed to the seed collection block assembly 300 by a metal fixing plate 320, which is made of iron.

[0036] Specifically, the monitor 210 includes a positive lead and a negative lead. The negative lead is electrically connected to the fixed duckbill 220 by a screw, and the duckbill assembly 200 is connected to the fixed plate assembly 100 by a rotating shaft. Both the rotating shaft and the fixed plate assembly 100 are made of metal with good conductivity, so the negative terminal of the monitor 210 is always electrically connected to the receiver 110.

[0037] It should be noted that since the seed conductor 230 is made of insulating material, it separates the positive and negative terminals of the monitor 210, thus preventing a short circuit.

[0038] The positive electrode of the monitor 210 is in contact with the metal fixing plate 320, which is fixedly connected to the fixing end 311 of the second conductive element 310 by metal bolts. The second conductive element 310 also has an elastic arm 312 extending from the fixing end 311. When the second conductive element 310 is in electrical contact with the first conductive element 112, the elastic arm 312 remains in contact with the first conductive element 112. In this embodiment, the second conductive element 310 is made of copper.

[0039] Therefore, the metal fixing piece 320 can not only fix the door curtain, but also be used to electrically connect the monitor 210 and the second conductive element 310.

[0040] The second conductive element 310 is fixed to the fixed end 311 of the seed-collecting block assembly 300, ensuring that the second conductive element 310 will not shift or loosen during operation due to the rotation of the moving disk assembly or other external forces. When the second conductive element 310 is in electrical contact with the first conductive element 112, the elastic arm 312 can maintain contact with the first conductive element 112 due to its own elasticity, avoiding poor contact. Even when the seeder shakes during operation, the elastic arm 312 can always maintain good contact with the first conductive element 112, ensuring the stability of the electrical connection between the monitor 210 and the receiver 110. In addition, the elastic arm 312 of the second conductive element 310 has the ability to elastically deform. During the rotation of the moving disk assembly, when the second conductive element 310 and the first conductive element 112 rotate relative to each other, the elastic arm 312 can buffer the movement through elastic deformation, reducing rigid collisions and friction between the two. This not only reduces the wear of the first conductive element 112 and the second conductive element 310 and extends their service life, but also ensures that the second conductive element 310 and the first conductive element 112 maintain good contact during long-term use, thus guaranteeing the normal operation of the monitoring circuit.

[0041] Specifically, such as Figure 8 As shown, the elastic arm 312 is a protruding structure formed by bending the first metal part itself. The vertical distance h1 from the protruding structure to the extension surface of the fixed end 311 is greater than the vertical distance h2 from the first conductive part 112 to the extension surface of the fixed end 311.

[0042] like Figure 9 As shown, during the rotation of the moving disk assembly, when the elastic arm 312 gradually approaches the first conductive element 112, since h1 > h2, the elastic arm 312 will undergo elastic deformation during the contact process with the first conductive element 112. This ensures that the elastic arm 312 and the first conductive element 112 always maintain a tight contact state. Even if there are factors such as vibration during the operation of the seeder, the elastic arm 312 has sufficient elastic deformation to maintain good contact with the first conductive element 112, thus ensuring the reliability of the electrical connection between the monitor 210 and the receiver 110.

[0043] Furthermore, the elastic arm 312 has a first inclined surface 313, and the first conductive element 112 has a second inclined surface 113. When the second conductive element 310 rotates to make electrical contact with the first conductive element 112, the first inclined surface 313 slides along the second inclined surface 113, guiding the elastic arm 312 to undergo elastic deformation, thus bringing the second conductive element 310 into contact with the first conductive element 112. This makes the contact between the second conductive element 310 and the first conductive element 112 a gradual process. As the first inclined surface 313 slides along the second inclined surface 113, the elastic arm 312 gradually deforms elastically, and the contact force between the two gradually increases. This reduces the impact of the contact between the first conductive element 112 and the second conductive element 310, reduces damage to the conductive components caused by impact, and extends the service life of the first conductive element 112 and the second conductive element 310. In addition, during the long-term operation of the seeder, this gentle contact method can effectively prevent the first conductive element 112 and the second conductive element 310 from loosening or being damaged due to repeated impacts.

[0044] In detail, the first conductive element 112 is made of copper and is located on the fixed plate assembly 100 in the fourth zone. The first conductive element 112 is electrically connected to the receiver 110. When the moving plate assembly rotates relative to the fixed plate assembly 100, only the second conductive element 310 of the duckbill assembly 200 in the fourth zone seeding state can contact the first conductive element 112. When the first conductive element 112 contacts the second conductive element 310, a monitoring circuit is formed.

[0045] In addition to the preferred embodiments described above, there are other embodiments of this utility model. All other embodiments obtained by those skilled in the art based on the embodiments of this utility model without creative effort are within the scope of protection claimed by this utility model.
