Description

Technical Field

[0001] This invention relates to the field of agricultural machinery technology, and in particular to a seeder. Background Technology

[0002] A seeder is a planting machine that sows crop seeds. Seeders used for a certain type or type of crop are often named after the crop, such as grain row seeders, corn hill seeders, cotton seeders, and pasture broadcasters. Seeders plant crop seeds or coated seeds that have been pelleted. According to the sowing method, they can be divided into three categories: vacuum seed seeders, broadcasters, row seeders, and hill seeders.

[0003] Traditional seeders often rely on manual adjustment based on experience to control seeding depth, making it difficult to make precise adjustments based on complex and ever-changing soil texture and moisture conditions. This results in inconsistent seed germination rates, which can easily affect nutrient supply to crops in the early stages of growth and reduce seedling survival rates. Summary of the Invention

[0004] The main objective of this invention is to provide a seeder that allows for adjustment of the seeding depth.

[0005] To achieve the above objectives, the present invention provides a seeder comprising:

[0006] frame;

[0007] A support frame is connected to the machine frame, and the support frame has a first limiting groove that extends in a downward direction.

[0008] A shovel assembly, wherein the shovel assembly is movably engaged in the first limiting groove;

[0009] The drive assembly includes a first drive member connected to the frame, the output end of the first drive member connected to the shovel assembly, and capable of driving the shovel assembly to reciprocate along the extension direction of the first limiting groove.

[0010] The control component includes a controller and a detection element. The detection element is communicatively connected to the controller and is used to detect soil conditions and feed them back to the controller, so that the controller controls and adjusts the depth to which the first drive element drives the shovel assembly to move downward.

[0011] In one embodiment, the shovel assembly includes a shovel and a baffle, the baffle being connected to the shovel and the baffle and the shovel forming a feeding channel, and the shovel being engaged in the first limiting groove.

[0012] In one embodiment, the seeder further includes a seeding assembly, which includes a fixed frame, a first storage bin, and a screw meter. The first storage bin has a receiving cavity for storing seeds. The fixed frame is connected to the frame, and the screw meter is connected to the bottom of the first storage bin to control the number of seeds output from the first storage bin. The output end of the screw meter is connected to the feeding channel.

[0013] In one embodiment, the sowing assembly further includes a second storage bin, which has a receiving cavity for storing fertilizer. The bottom of the second storage bin is connected to a conveying pipe, which communicates with the discharge channel. The conveying pipe is equipped with a solenoid valve, and the controller is communicatively connected to the solenoid valve to control the opening and closing of the channel inside the conveying pipe.

[0014] In one embodiment, the seeder further includes a second drive unit connected to the shovel plate, the output end of the second drive unit being connected to the baffle plate and capable of driving the baffle plate closer to or further away from the shovel plate.

[0015] In one embodiment, the seeder further includes a vibration assembly, which includes a connector, a pressure plate, a support, a vibrating element, and an elastic element. The pressure plate is connected to the vibrating element, the support is connected to the support frame, and the two ends of the elastic element extending in the direction of extension are respectively connected to the vibrating element and the support. The end of the vibrating element away from the pressure plate is connected to the baffle, and the two ends of the connector extending in the direction of extension are respectively connected to the output end of the first drive element and the pressure plate.

[0016] In one embodiment, the support frame further forms a second limiting groove, which extends along the extension direction of the elastic member, and the vibrating member is engaged in the second limiting groove.

[0017] In one embodiment, the elastic element is a spring.

[0018] In one embodiment, the detection element includes a soil sensor and a humidity sensor, which are spaced apart at the bottom end of the support frame.

[0019] In one embodiment, the seeder further includes guide wheels and a handle, the guide wheels being located at the bottom of the frame and the handle being connected to the frame.

[0020] The present invention provides a seeder in which the frame serves as the basic support structure, providing mounting and fixing positions for other components and ensuring the stability and integrity of the entire device. A support frame is connected to the frame and forms a first limiting groove extending obliquely downwards. A first driving component drives the shovel assembly to reciprocate obliquely, facilitating soil turning for sowing. The control component includes a controller and a detection component. The detection component detects soil conditions and feeds feedback to the controller, which then adjusts the depth at which the first driving component drives the shovel assembly downwards based on this feedback information. This enables the seeder to adaptively adjust to different soil conditions, ensuring the rationality and accuracy of the sowing depth. This allows the seeder to better adapt to complex and changing farmland soil environments, thereby improving sowing quality and creating favorable conditions for subsequent seed germination and growth.

[0036] A seeder is a planting machine that sows crop seeds. Seeders used for a certain type or type of crop are often named after the crop, such as grain row seeders, corn seeders, cotton seeders, and pasture broadcasters. Seeders plant crop seeds or coated seeds that have been pelleted. According to the sowing method, they can be divided into three categories: vacuum seeders, broadcasters, row seeders, and hill seeders.

[0037] Traditional seeders often rely on manual adjustment based on experience to control seeding depth, making it difficult to make precise adjustments based on complex and ever-changing soil texture and moisture conditions. This results in inconsistent seed germination rates, which can easily affect nutrient supply to crops in the early stages of growth and reduce seedling survival rates.

[0038] To solve the above problems, please refer to... Figures 1 to 8 This invention proposes a seeder 100, including a frame 1, a support frame 2, a shovel assembly 3, a drive assembly, and a control assembly. The support frame 2 is connected to the frame 1 and has a first limiting groove 21 extending in a downward direction. The shovel assembly 3 is movably engaged in the first limiting groove 21. The drive assembly includes a first drive member 41 connected to the frame 1, with its output end connected to the shovel assembly 3, and capable of driving the shovel assembly 3 to reciprocate along the extension direction of the first limiting groove 21. The control assembly includes a controller 51 and a detection member 52. The detection member 52 is communicatively connected to the controller 51 and is used to detect soil conditions and feed them back to the controller 51, so that the controller 51 controls and adjusts the depth to which the first drive member 41 drives the shovel assembly 3 downward.

[0039] The present invention provides a seeder 100. The frame 1 serves as the basic support structure of the entire seeder 100, providing installation and fixing positions for other components, ensuring the stability and integrity of the entire device. A support frame 2 is connected to the frame 1 and forms a first limiting groove 21 extending obliquely downwards. A first driving member 41 drives the shovel assembly 3 to reciprocate obliquely, facilitating soil turning for sowing. The control component includes a controller 51 and a detection member 52. The detection member 52 detects soil conditions and feeds feedback to the controller 51. The controller 51 then controls and adjusts the depth of the shovel assembly 3 driven by the first driving member 41 based on this feedback information. This enables the seeder 100 to adaptively adjust to different soil conditions, ensuring the rationality and accuracy of the sowing depth. This allows the seeder 100 to better adapt to complex and changing farmland soil environments, thereby improving sowing quality and creating favorable conditions for subsequent seed germination and growth. It should be noted that the communication connection mentioned here can be either wired or wireless. A wired connection uses cables or fiber optics to directly connect the controller 51 and the detection element 52 for electrical control. A wireless connection uses electromagnetic wave transmission to achieve communication between the controller 51 and the detection element 52. The choice can be made according to actual needs. Specifically, the controller 51 is a programmable logic controller (PLC). The PLC 51 has data storage, analysis, and remote communication functions, and can be remotely monitored and parameter set via mobile terminals or computers. By incorporating the PLC 51, this controller 51 integrates powerful data storage, in-depth analysis, and efficient remote communication functions. Users can flexibly cope with various complex and changing operating scenarios, greatly improving the convenience and efficiency of seeding operation management.

[0040] In an optional embodiment, to facilitate sowing after the shovel assembly 3 turns over the soil, please refer to... Figure 1 , Figure 2 , Figure 3 as well as Figure 5 The shovel assembly 3 includes a shovel 31 and a baffle 32. The baffle 32 is connected to the shovel 31, and the baffle 32 and the shovel 31 enclose a material feeding channel. The shovel 31 is engaged in the first limiting groove 21.

[0041] The shovel plate 31 is mainly responsible for ditching and other operations in contact with the soil. The material discharge channel formed by the baffle plate 32 and the shovel plate 31 provides a fixed channel for seed delivery, ensuring that the seeds fall accurately into the soil treated by the shovel plate 31, avoiding seed scattering or uneven distribution. The shovel plate 31 is engaged in the first limiting groove 21, ensuring the stability and accuracy of the entire shovel plate assembly 3 during movement. This allows the material discharge channel to change accurately as the shovel plate 31 moves, better coordinating with the sowing work, improving the accuracy and uniformity of sowing, and facilitating the rational distribution of seeds in the soil, thereby improving seed germination rate and crop growth quality.

[0042] In an optional embodiment, for ease of precise seeding, please refer to... Figure 1 , Figure 2 ,as well as Figure 4 The seeder 100 also includes a seeding assembly, which includes a fixed frame 61, a first storage box 62, and a screw meter 63. The first storage box 62 has a receiving cavity for storing seeds. The fixed frame 61 is connected to the frame 1. The screw meter 63 is connected to the bottom of the first storage box 62 to control the number of seeds output by the first storage box 62. The output end of the screw meter 63 is connected to the feeding channel.

[0043] The fixing frame 61 is connected to the frame 1, providing a stable mounting base for the sowing assembly and ensuring the stability of the entire sowing assembly during operation. The first storage bin 62 has an internal cavity for storing seeds, and an inlet is located at the top of the first storage bin 62 to facilitate seed input into the cavity. The screw meter 63 is connected to the bottom of the first storage bin 62, precisely controlling the quantity of seeds output. It accurately measures the seed output by controlling the screw's rotation speed and number of rotations, ensuring that the number of seeds at each sowing point meets the preset requirements during the sowing process, avoiding seed waste or overly dense or sparse sowing. The output end of the screw meter 63 is connected to the feeding channel, allowing the metered seeds to smoothly and accurately enter the feeding channel and fall into the soil, ensuring the continuity and smoothness of seed delivery, improving the working efficiency and sowing quality of the seeder 100, and making the sowing process more standardized and precise.

[0044] In an optional embodiment, for ease of fertilization during sowing, please refer to... Figure 1 , Figure 2 ,as well as Figure 4The seeding assembly also includes a second storage box 64, which has a cavity for storing fertilizer. The bottom of the second storage box 64 is connected to a conveying pipe 641, which is connected to a discharge channel. The conveying pipe 641 is equipped with a solenoid valve 642. The controller 51 is connected to the solenoid valve 642 to control the opening and closing of the channel inside the conveying pipe 641.

[0045] By incorporating a second storage bin 64 to hold fertilizer, the seeder 100 can simultaneously carry seeds and fertilizer for sowing operations. A conveying pipe 641 is connected to the bottom of the second storage bin 64, which connects to a discharge channel to deliver fertilizer to the soil. The conveying pipe 641 is equipped with a solenoid valve 642, and the controller 51 communicates with the solenoid valve 642, allowing for control of the opening and closing of the channels within the conveying pipe 641 as needed. This enables the seeder 100 to precisely control the timing and amount of fertilizer application according to a preset fertilization method and the actual needs of the soil while sowing seeds, achieving simultaneous seed and fertilizer application. This improves the integration and efficiency of the sowing operation, reduces the need for separate fertilization, and saves time and labor costs. Furthermore, precise fertilization control helps avoid over- or under-fertilization, improving fertilizer utilization.

[0046] In an optional embodiment, for ease of synchronizing sowing and fertilization, please refer to... Figure 3 and Figure 5 The seeder 100 also includes a second drive unit 42, which is connected to the shovel plate 31. The output end of the second drive unit 42 is connected to the baffle plate 32 and can drive the baffle plate 32 to move closer to or away from the shovel plate 31.

[0047] Specifically, to facilitate simultaneous sowing and fertilization, the shovel plate 31 and baffle plate 32 can be set to a semi-enclosed state. During the sowing operation, the controller 51 controls the screw metering device 63 and the solenoid valve 642 to input the seeds and fertilizer required for a single sowing into the feeding channel inside the shovel plate assembly 3. At this time, the shovel plate 31 and the baffle plate 32 are in a closed and fitted state, and the seeds and fertilizer are in the feeding channel and cannot fall. When the shovel plate assembly 3 descends and turns over the soil, the controller 51 controls the second driving component 42 to drive the baffle plate 32 away from the shovel plate 31. The seeds and fertilizer gradually fall into the soil under their own gravity, thereby achieving simultaneous sowing and fertilization and ensuring the accuracy of sowing and fertilization. In addition, a partition can also be set on the baffle plate 32 to separate the seeds and fertilizer, so that the seeds and fertilizer can maintain a certain distance after falling into the soil, avoiding direct contact between the fertilizer and the seeds, which could cause seed burning. The opening and closing mechanism of the shovel plate 31 and the baffle plate 32 also helps to control the width of the furrow. By spreading the soil on both sides of the shovel plate 31 and the baffle plate 32, it is easier for seeds and fertilizers to fall onto the top of the soil, which helps to ensure the sowing depth. After sowing, the first drive component 41 drives the shovel plate assembly 3 to move upward, and the soil turned over by the shovel plate assembly 3 returns to its original position to cover the seeds and fertilizers, thus achieving soil covering. In this way, sowing, fertilization and soil covering operations are realized simultaneously, improving the efficiency and convenience of sowing operations.

[0048] In an optional embodiment, to prevent seeds and fertilizer from sticking to baffle 32, please refer to... Figure 2 , Figure 3 , Figure 5 as well as Figure 6 The seeder 100 also includes a vibration assembly, which includes a connector 71, a pressure plate 72, a support 73, a vibrating element 74, and an elastic element 75. The pressure plate 72 is connected to the vibrating element 74, the support 73 is connected to the support frame 2, the two ends of the elastic element 75 in the extension direction are respectively connected to the vibrating element 74 and the support 73, the end of the vibrating element 74 away from the pressure plate 72 is connected to the baffle 32, and the two ends of the connector 71 in the extension direction are respectively connected to the output end of the first drive element 41 and the pressure plate 72.

[0049] The end of the shovel plate 31 is engaged in the first limiting groove 21 and extends outward to connect with the connector 71. The two ends of the connector 71 are respectively connected to the output end of the first driving member 41 and the pressure plate 72. The first driving member 41 drives the connector 71 to move downward, thereby driving the shovel plate assembly 3 and the pressure plate 72 downward. The pressure plate 72 exerts pressure on the elastic member 75, causing it to undergo elastic deformation and accumulate elastic potential energy. When the shovel plate assembly 3 completes the trenching, the first driving member 41 moves upward to reset. The elastic member 75 loses its constraint and releases its elastic potential energy, which exerts a force on the vibrating member 74, causing it to drive the baffle 32 to vibrate. On the one hand, this can prevent seeds and fertilizers from adhering to the baffle 32, effectively preventing seeds or fertilizers from blocking or bridging in the feeding channel during the sowing process. On the other hand, the vibration also helps to loosen the soil, allowing the soil to better combine with seeds and fertilizers to a certain extent, improving the sowing and fertilization effect, and creating more favorable conditions for seed germination and growth.

[0050] For further details, please refer to... Figure 2 , Figure 3 as well as Figure 6 The support frame 2 also has a second limiting groove 22, which extends along the extension direction of the elastic member 75, and the vibrating member 74 is engaged in the second limiting groove 22.

[0051] The movement trajectory of the vibrating element 74 is limited by the second limiting groove 22, ensuring that the vibrating element 74 can only move within the range of the second limiting groove 22 along the extension direction of the elastic element 75. This guarantees the stability and accuracy of the movement of the vibrating element 74. It avoids instability such as deviation, swaying, or excessive swinging of the vibrating element 74 during operation, helps to precisely control the amplitude and direction of vibration, and thus ensures a more uniform and stable vibration effect of the baffle 32. This better enables the vibrating assembly to play its role in preventing blockage and promoting the falling of seeds and fertilizers, improving the reliability and stability of the entire seeder 100's operation.

[0052] In an optional embodiment, the elastic element 75 is a spring. A spring is a common elastic element with good and stable elastic properties. Using a spring as the elastic element 75 provides a stable, continuous, and appropriately sized elastic force, enabling the vibrating element 74 to generate appropriate vibration amplitude and frequency when subjected to driving and external forces, and to quickly return to its initial position when no force is applied, ensuring the normal operation cycle of the vibrating assembly. Simultaneously, the spring structure is relatively simple, low-cost, and easy to install and maintain, which helps reduce the overall production cost and maintenance difficulty of the seeder 100, improving the equipment's economy and practicality. In other embodiments, the elastic element 75 can also be a leaf spring or a compression spring, selected according to actual needs.

[0053] In an alternative embodiment, please refer to Figures 1 to 3The detection component 52 includes a soil sensor 521 and a humidity sensor 522, which are spaced apart at the bottom of the support frame 2.

[0054] Soil sensor 521 can monitor various physical and chemical properties of the soil in real time, such as soil texture, fertility, and pH; humidity sensor 522 can detect soil moisture content. This information, acquired by the sensors, is fed back to controller 51. Based on this detailed soil condition data, controller 51 can more precisely adjust the depth of the first drive component 41 driving the shovel assembly 3 downwards, achieving intelligent control of the sowing depth to meet the requirements of different crops for different sowing depths, and improving the adaptability of the seeder 100 to various types of crops and different soil conditions. Furthermore, the data from humidity sensor 522 can also help determine whether the soil needs irrigation, providing a reference for the entire agricultural planting process, improving the intelligence level of the seeder 100 and its adaptability to the farmland environment.

[0055] In an alternative embodiment, please refer to Figure 1 The seeder 100 also includes guide wheels 8 and handles 9. The guide wheels 8 are located at the bottom of the frame 1, and the handles 9 are connected to the frame 1.

[0056] When the seeder 100 is working, the guide wheel 8 contacts the ground, providing stable guidance for the seeder 100 to move forward. This ensures that the seeder 100 can travel along the predetermined route, avoiding deviation from the sowing area or uneven sowing, thus improving the accuracy and uniformity of sowing. This is beneficial for standardized crop planting and subsequent field management. The handle 9 is connected to the frame 1, providing the operator with a convenient position to operate and control the seeder 100. The operator can easily push and control the direction and speed of the seeder 100 through the handle 9, and it also facilitates manual intervention and adjustment of the seeder 100 when necessary. This improves the ease of operation and human-machine interaction of the seeder 100, making sowing work more convenient and efficient.

[0057] Please refer to Figure 7 and Figure 8When cultivating different types of soil, the soil condition (such as humidity, hardness, etc.) is detected by soil sensor 521 and humidity sensor 522 and fed back to controller 51. Controller 51 calculates the cultivation depth H, H = 0.8Sh + Mh (Sh is the hardness detection value and Mh is the humidity detection value), and sends a control signal to control and adjust the stroke of the first drive component 41 according to the calculation result, thereby realizing automatic control and adjustment of the tillage depth. It also realizes remote monitoring and interaction of seeder 100 through mobile terminal or computer. Controller 51 controls and interacts with actuators such as second drive component 42, solenoid valve 642, and screw meter 63, thereby setting the seed and fertilizer spreading amount and the single furrow width of shovel plate assembly 3. All of these can be completed on the remote operation interface, realizing human-machine interaction between user and seeder 100 and improving the automation of sowing operation.
