[0034] The following will be combined with the drawings in the specification of the present invention to clearly and completely describe the technical solutions in the embodiments of the present invention. Obviously, the described embodiments are only part of the embodiments of the present invention, not all of the embodiments. Based on the embodiments of the present invention, all other embodiments obtained by ordinary technicians in this field without creative work are within the scope of protection of the present invention.

[0035] Please see attached Figure 1 - Attachment Fig. 9The embodiment of the present invention provides an automatic navigation agricultural sowing device, comprising a mounting base plate 1, a special crawler 2 is mounted on the bottom of the mounting base plate 1, a quantitative box 501 is fixedly connected to one side of the top of the mounting base plate 1, a rotating disk 508 is rotatably connected to the inside of the quantitative box 501, a fixed block 507 is fixedly connected to the eccentric position of the outer side of the rotating disk 508, two limit plates 505 are fixedly connected to the inner side wall of the mounting base plate 1, a movable plate 506 is slidably connected to the inner side of the limit plate 505, a driving rod 504 is fixedly connected to the outer side of the movable plate 506, a rubber piston 503 is fixedly connected to one end of the driving rod 504, a first connecting pipe 502 is connected to the bottom of the quantitative box 501, a control valve is mounted on the outer side of the first connecting pipe 502, the fixed block 507 is driven to rotate eccentrically by the rotation of the rotating disk 508, and then the movable plate 506 and the driving rod 504 are driven to move back and forth left and right, so that the rubber piston 503 moves inside the quantitative box 501, and quantitative fertilization is achieved. A pump body 701 is fixedly connected to one side of the top of the installation base plate 1, and a second transport pipe 703 is fixedly connected to the output end of the pump body 701, and a first transport pipe 702 is fixedly connected to the input end of the second transport pipe 703. One end of the first transport pipe 702 is connected to the outside of the liquid storage tank 8, and the other end of the second transport pipe 703 is connected to the outside of the quantitative tank 501. A groove is provided on the inner side of the movable plate 506, and the fixed block 507 is movably connected to the inside of the groove.

[0036] Specifically, the mounting base plate 1 is the supporting structure of the entire device, and a special crawler 2 is installed at the bottom. The crawler design enables the device to travel stably under various terrain conditions, and is particularly suitable for the complex environment of agricultural fields. This crawler system ensures the mobility and adaptability of the agricultural sowing device, and can efficiently complete the sowing work of large areas of farmland.

[0037] One end of the driving rod 504 is fixedly connected to the rubber piston 503. Through the reciprocating motion of the driving rod 504, the rubber piston 503 moves along a certain track inside the quantitative box 501. When the rubber piston 503 moves, the fertilizer inside the quantitative box 501 is accurately discharged to the downstream pipeline. Since the length of the driving rod 504 is fixed, the amount of fertilizer applied each time is precisely controllable. This design ensures the accuracy of the amount of fertilizer applied and can avoid excessive use or waste of fertilizer.

[0038] The pump body 701 is used to deliver fertilizer from the liquid storage tank 8 into the quantitative box 501 through the first transport pipe 702. The output end of the pump body 701 is connected to the quantitative box 501 through the second transport pipe 703 to ensure that the fertilizer can flow into the quantitative box 501 for precise fertilization. The use of the pump body 701 makes the delivery of fertilizer more stable, and the operation of the fertilization system is controlled by the dual-axis motor 601 to achieve comprehensive regulation of the agricultural sowing process.

[0039] Specifically, after the pump body 701 is started, the fertilizer in the liquid storage tank 8 is delivered to the quantitative tank 501 through the first transport pipe 702. When the fertilizer enters the quantitative tank 501, the eccentric rotation of the rotating disk 508 drives the fixed block 507 to move eccentrically, and further drives the movable plate 506 to reciprocate left and right along the limit plate 505. Under the traction of the driving rod 504, the rubber piston 503 moves synchronously, and through this movement, the fertilizer is quantitatively discharged into the first connecting pipe 502.

[0040] As the rubber piston 503 reciprocates, the fertilizer in the metering box 501 is delivered in a uniform and precise manner. This process not only realizes the quantitative application of fertilizer, but also controls the precise amount of fertilizer applied each time, avoiding the problem of excessive or insufficient fertilizer. In order to adjust the amount of fertilizer released, it is only necessary to adjust the initial position of the rubber piston 503, and the amount of fertilizer applied can be flexibly adjusted without changing other components of the system.

[0041] A liquid storage tank 8 is fixedly connected to the middle side of the top of the installation base plate 1, a dual-axis motor 601 is installed on the top of the liquid storage tank 8, a driving gear 602 is fixedly connected to the bottom output end of the dual-axis motor 601, a support frame 603 is installed inside the dual-axis motor 601, and three mounting parts are arranged on the outside of the support frame 603, the inner sides of the three mounting parts are all rotatably connected with a rotating shaft, one end of the rotating shaft is fixedly connected to a driven gear 604, the other end of the rotating shaft is fixedly connected to a driving disk 605, a stirring rod 606 is fixedly connected to the outer eccentric part of the driving disk 605, and the outer sides of multiple driven gears 604 are meshed with the outer sides of the driving gear 602.

[0042] Specifically, the liquid storage tank 8 is fixedly mounted on the top middle side of the mounting base plate 1. The mounting base plate 1 serves as a supporting structure, carrying the liquid storage tank 8 and the subsequent driving system to ensure that the stirring system can operate stably. The liquid storage tank 8 is used to store the fertilizer solution or liquid fertilizer to be stirred and provide a container environment to contain the fertilizer.

[0043] The driving gear 602 drives the multiple driven gears 604 to rotate synchronously. Specifically, the driving gear 602 transmits power to the multiple driven gears 604 through gear transmission. The outer sides of the multiple driven gears 604 are meshed and connected with the outer sides of the driving gear 602, and rotate together, thereby achieving a multi-point, synchronous transmission effect. This transmission method ensures that during the operation of the entire mixing system, all rotating parts can move in a coordinated and efficient manner.

[0044] The driving disk 605 is provided with an eccentric design on the outside, and a stirring rod 606 is fixedly connected to the eccentric position. The stirring rod 606 generates an eccentric rotational motion under the rotation of the driving disk 605. Due to the eccentric design, the stirring rod 606 generates centrifugal force during the rotation process, which enables the stirring rod 606 to form a strong stirring effect inside the liquid storage tank 8. In this way, the stirring rod 606 can effectively mix the fertilizer evenly, avoid stratification or precipitation of fertilizer components, and ensure that the fertilizer can achieve the desired effect during the application process.

[0045] The fertilizer stirring device of the present invention starts the dual-shaft motor 601 to drive the driving gear 602 to rotate. The driving gear 602 drives multiple driven gears 604 to rotate synchronously through gear transmission. Under the joint action of the rotating shaft and the driving disk 605, the driving disk 605 rotates synchronously and drives the eccentric stirring rod 606 to produce eccentric movement. During the operation, the stirring rod 606 efficiently mixes the fertilizer in the liquid storage tank 8 to avoid stratification or precipitation of fertilizer components, thereby improving the uniformity and stability of the fertilizer.

[0046] It also includes a sowing component, which includes two storage boxes 301, both of which are fixedly connected to the front side of the mounting base 1, a fixed cylinder 302 is fixedly connected to the bottom of the storage box 301, a driving motor 305 is fixedly connected to the outer side of the fixed cylinder 302, a rotating rod 306 is fixedly connected to the output end of the driving motor 305, a plurality of sowing blades 307 are fixedly connected to the outside of the rotating rod 306, a plurality of sowing grooves 308 are provided on the outside of the fixed cylinder 302, a mounting frame 303 is fixedly connected to the outer side of the storage box 301, a rotating rod 306 is rotatably connected to the inner side of the mounting frame 303, and a plurality of soil-turning blades 304 are fixedly connected to the outer side of the rotating rod 306.

[0047] Specifically, the driving motor 305 starts to work, and the power generated drives the rotating rod 306 to rotate through the bevel gear transmission assembly.

[0048] The soil turning blade 304 rotates with the movement of the rotating rod 306 to loosen the soil. Loose soil is conducive to the germination of seeds and can provide enough moisture and air for the seeds.

[0049] As the rotating rod 306 rotates, the sowing blade 307 also rotates. The sowing blade 307 transports the seeds in the storage box 301 to the soil through the sowing groove 308. The rotation of the blade is not only for sowing, but also helps to evenly distribute the seeds and avoid over-concentrated sowing.

[0050] During the sowing process, the seeds enter the device through the fixed cylinder 302. Driven by the rotating rod 306, the sowing blades 307 discharge the seeds to the ground to ensure that the seeds can be evenly sown. The design of the sowing blades 307 can ensure that the seeds enter the soil smoothly, and the sowing depth and spacing are properly controlled.

[0051] The outer side of the mounting frame 303 is rotatably connected to a transmission rod 401, and the left and right ends of the transmission rod 401 are fixedly connected to a first bevel gear 402. The rotating rod 306 and one end of the rotating rod 306 are fixedly connected to a second bevel gear 403, and the outer sides of the two second bevel gears 403 are meshed with the outer sides of the first bevel gear 402.

[0052] The top output end of the dual-axis motor 601 is connected to the outer side of the rotating disk 508 through a transmission assembly. The transmission assembly includes two synchronous wheels, one of which is fixedly connected to the top output end of the dual-axis motor 601, and the other two synchronous wheels are fixedly installed on the outer side of the rotating disk 508, and the two synchronous wheels are connected by a synchronous belt.

[0053] Specifically, the dual-axis motor 601 provides rotational power through the top output terminal, and the power is transmitted to the synchronous belt through the first synchronous wheel, and then the second synchronous wheel is driven by the synchronous belt, and finally the rotation of the rotating disk 508 is realized. The combination of the synchronous belt and the synchronous wheel ensures stable and accurate power transmission during the transmission process.

[0055] Positioning module, used for precise time positioning;

[0056] A control module, used for processing data and controlling the automatic driving of the seeding device;

[0057] Specifically, it includes data processing: by real-time processing of data from devices such as positioning modules, sensors and cameras, the control module can determine the current position, speed, direction, etc. of the device, and automatically adjust the driving trajectory according to the path planning algorithm.

[0058] Automatic control system: The control module is connected to the hardware interfaces such as the motor, transmission system, and steering system, and can automatically adjust the speed and direction of the equipment to avoid manual intervention

[0059] Communication module, used for real-time data exchange between devices;

[0060] Specifically, the agricultural seeding system needs to interact with the remote cloud platform or monitoring center for data. The communication module can transmit the status, task progress and location information of the equipment in real time. Remote users can view the status of the equipment through mobile phones, computers and other devices, and perform remote control.

[0061] Display and operation interface, used to provide real-time information and operation control to the operator;

[0062] Specifically, the agricultural seeding system may need to interact with the remote cloud platform or monitoring center for data. The communication module can transmit the status, task progress and location information of the equipment in real time. Remote users can view the status of the equipment through mobile phones, computers and other devices and perform remote control.

[0063] Path planning and navigation algorithms to calculate the optimal path and ensure accurate device tracking;

[0064] Specifically, its contents include:

[0065] Path planning: Based on the actual shape of the field and the sowing requirements, the system uses an algorithm to calculate the optimal path. These paths can be straight, curved or gridded to ensure that all sowing areas are covered and duplicate sowing is avoided.

[0066] Precise navigation: After the path planning is completed, the navigation algorithm will adjust the device's driving route in real time to ensure that the device follows the optimal path and avoids deviation caused by mechanical errors or external interference. Navigation technologies include:

[0067] Autonomous driving algorithm: Use algorithms such as PID control and model predictive control (MPC) to ensure that the equipment can perform path navigation smoothly and accurately.

[0068] Boundary recognition: Scan the boundaries of farmlands through sensors (such as lidar, ultrasound, etc.) to ensure that the equipment does not deviate from the track at the edges and turns.

[0069] Obstacle avoidance: If there is an obstacle on the path, the navigation system will automatically calculate a new path to avoid collision between the device and the obstacle.

[0070] Precision seeding control module to achieve precise seeding control.

[0071] Specifically, the precision seeding control module is used to control the working status of the seeding device in real time to ensure that the seeds can be sown at the appropriate depth, spacing and density. This module is usually combined with soil sensors, climate sensors and other equipment to adjust the seeding strategy according to soil conditions and climate conditions.

[0072] Working principle: The device is used specifically to control the movement of the device by adding a navigation system. At this time, the driving motor 305 is started to drive the rotating rod 306 to rotate synchronously, which further drives the second bevel gear 403 to rotate, and further the first bevel gear 402 engaged therewith rotates. At this time, the transmission rod 401 rotates along and drives another second bevel gear 403 to rotate, which drives the rotating rod 306 and the sowing blade 307 to rotate, and the soil is turned over by the sowing blade 307. At this time, the seeds in the storage box 301 enter the interior of the fixed cylinder 302. In addition, the rotation of the rotating rod 306 drives multiple sowing blades 307 to rotate, and the seeds are discharged through the sowing groove 308 to achieve sowing;

[0073] In addition, by starting the dual-axis motor 601, the driving gear 602 is driven to rotate, thereby driving the multiple meshing driven gears 604 to rotate synchronously, and further driving the driving disk 605 to rotate synchronously, so that the stirring rod 606 rotates eccentrically, and the fertilizer inside the liquid storage tank 8 is efficiently mixed by the stirring rod 606, which can effectively avoid the phenomenon of stratification or precipitation of fertilizer components, so that the fertilizer can achieve higher uniformity and stability during the application process. Thereby improving the effectiveness of the fertilizer;

[0074] By starting the pump body 701, the fertilizer in the liquid storage tank 8 enters the second transport pipe 703 through the first transport pipe 702, and then enters the quantitative box 501 through the second transport pipe 703. At this time, the output end of the double-axis motor 601 drives the rotating disk 508 to rotate coaxially through the transmission assembly, which further drives the fixed block 507 to rotate eccentrically. Since the fixed block 507 moves in the groove inside the movable plate 506, the movable plate 506 is driven to move back and forth along the inner wall of the limit plate 505. Under the traction force of the driving rod 504, the rubber The rubber piston 503 moves synchronously. When the cavity inside the quantitative box 501 is filled with fertilizer, the fertilizer is discharged through the first connecting pipe 502 as the rubber piston 503 moves to the right. When the rubber piston 503 moves to the left, the cavity is filled with fertilizer again. Since the length of the driving rod 504 is fixed, the amount of fertilizer applied each time is also fixed. When the amount of fertilizer needs to be changed, it is only necessary to change the initial position of the rubber piston 503. In this way, through precise quantitative fertilization control, the amount of fertilizer applied is intelligently adjusted according to various factors such as the growth stage of the crop and soil fertility, and accurate fertilizer delivery is achieved. In this way, excessive use of fertilizer is effectively avoided, the utilization rate of fertilizer is improved, and thus the cost and negative impact on the environment are reduced.

[0075] Although embodiments of the present invention have been shown and described, it will be appreciated by those skilled in the art that various changes, modifications, substitutions and variations may be made to the embodiments without departing from the principles and spirit of the present invention, and that the scope of the present invention is defined by the appended claims and their equivalents.
