Abstract
Description
Technical Field
[0001] The present invention relates to the technical field of crop sowing, and in particular to an all-in-one crop sowing machine, a sowing system and a working method. Background Art
[0002] Taro has a long history and important position in my country. It is one of my country's traditional crops. Large taro, mainly Lipu taro, has been widely planted in many regions of my country, while small taro, mainly Luochuan taro, has problems such as low survival rate of seedlings, time-consuming manual sowing, low yield and high market price. This not only makes it difficult for the small taro planting industry to scale up, but also limits its market competitiveness and development prospects.
[0003] At this stage, the key development direction of Xingnong Machinery has always been focused on large-scale crop sowing or harvesting, which is often suitable for essential grains such as wheat, corn, and potatoes. Because most of these crops have no special sowing requirements, strong adaptability to the growth environment and high survival rate, they are often sown in large areas and large quantities. Mature large-scale automated sowing equipment already exists at home and abroad and is applied in actual agricultural production; while for small taro, yam, lotus root and other crops that have special sowing requirements or are not suitable for intensive sowing, ridge turning, sowing, film covering, harvesting and other tasks are generally done manually. At the same time, there are also problems such as low seedling survival rate, long labor time, and difficulty in monitoring the entire life cycle of crops.
[0004] At present, when sowing crops with special requirements for sowing, a straight-cylinder mechanism is often used for sowing and a transmission gear is used to make the rack on the shovel mesh with the worm to rotate and dig holes. However, it is difficult to distinguish the direction of the sprouts of the crops when using the straight-cylinder mechanism, and at the same time, when the hole-digging structure uses gears, it undergoes two transmissions, resulting in low transmission efficiency and slow hole digging. When the straight-cylinder mechanism transmits crops with different sprout directions, the hole digging work is not completed, and the crops are usually half-buried in the soil at different inclination angles, making it difficult to achieve excellent sowing effects. Summary of the invention

[0015] Preferably, it also includes a fertilization mechanism, an irrigation mechanism and a film covering mechanism;

[0022] The embodiment of the present invention further provides a working method of a crop seeding machine, comprising the following steps:
[0023] The screw driven by the reduction motor moves the crops coming from the acrylic seed box so that the sprouts of the crops face upward and come out from the mouth of the arc-shaped pipe tube. After the seed cup reaches the predetermined position in advance, the mechanical arm rotates and controls the multiple wire-driven paddles in the seed cup to extend and retract to catch the crops.
[0024] When the robotic arm rotates to the sowing position, that is, when it rotates to the top of the digging mechanism, the digging mechanism controls the spherical worm gear at the connection of multiple acrylic brackets to rotate, driving the rack on the inner side of each acrylic bracket to move downward so that the digging shovel cooperates to dig holes.

[0025] The embodiments of the present invention provide an integrated crop sowing machine, a sowing system and a working method. Compared with the prior art, the beneficial effects thereof are as follows:
[0026] The invention uses a screw rod driven by a reduction motor inside the arc-shaped pipe tube to move the crops coming from the acrylic seed box so that the direction of the sprouts is upward and the sprouts come out from the pipe mouth of the arc-shaped pipe tube. After the seed cup reaches the predetermined position in advance, the mechanical arm rotates and controls multiple wire-driven paddles in the seed cup to extend and retract to catch the crops. When the mechanical arm rotates to the sowing position, that is, when it rotates to the top of the hole digging mechanism, the hole digging structure controls the spherical worm at the connection of multiple acrylic brackets to rotate, driving the rack inside each acrylic bracket to move downward so that the digging shovel cooperates to dig The holes are dug, that is, the tips of multiple digging shovels are driven to close at the same time to complete the hole digging work. At the same time, multiple line-driven paddles are extended and retracted again to make the crops fall into the soil with the sprouts facing upward. Multiple digging shovels move upward so that the digging shovels cooperate with backfilling soil to carry out sowing. When sowing, the direction of the crop sprouts is controlled, and the hole digging is driven by the spherical worm gear to drive the racks on the inner side of the four acrylic brackets. The transmission is carried out once in the form of a 1:1 transmission ratio, which greatly improves the hole digging efficiency and makes the crops quickly buried in the soil in the correct posture, greatly improving the sowing effect.
[0027] In addition, the present invention conducts modular design on the seeder, which can coordinate work systematically when sowing. If new functional mechanisms need to be added, each mechanism can be flexibly disassembled and assembled according to work needs, thereby ensuring its professionalism when performing different tasks.
[0028] Moreover, by arranging sensors, Beidou navigation modules, 5G communication modules and Bluetooth modules on the seeder, the present invention can not only ensure the accuracy of sowing and management work, but also detect and manage the status of crops remotely.

[0050] See also Figure 1 to Figure 3 The embodiment of the present invention provides an integrated crop sowing machine, a sowing system and a working method, including a seed box module, a hole digging module, a seed placing module, a fertilizing module, an irrigation module and a film covering module; it also includes a management mechanism, which is divided into a communication module and a monitoring module. The communication module uploads work instructions through the Bluetooth module, and the 5G module feeds back the monitoring data to the Onenet cloud platform. Users can view it in real time through a mobile phone app or a computer. The robot electronic control is mainly programmed and controlled using the Arduino program. Specifically including:
[0051] 1. Seed box module design.
[0052] 1. The overall structure of the seed box.
[0053] The seed box is divided into two layers, each layer can hold 10 small taro, and a maximum of 3*10 taro can be stored; each taro seedling is separated into storage bins by partitions, and the upper and lower layers are connected by a four-link pull-out structure of the partition. After the lower layer is sown, the partition can be pulled out to keep the taro seedlings on the upper layer with the bud tip facing up and drop to the lower layer. The overall length, width and height of the seed box are 590mm*300mm*200mm, and the size of each storage bin is 75mm*56mm*80mm.
[0054] 2. Partition pulling mechanism.
[0055] In order to ensure the orderliness and convenience of sowing, the partition pull-out structure of the seed box uses a four-bar linkage. When the taro does not need to fall, the partition moves to the front end and fits tightly against the side plate of the seed box. When it needs to fall, the motor drives the crankshaft to rotate, and the partition moves backward along the guide rail through the connecting rod transmission to ensure that the taro seedlings fall smoothly. Figure 4 and Figure 5 shown.
[0056] The four-bar linkage consists of a crank (replaced by a gear) and two connecting rods. However, due to the symmetrical distribution of the mechanism, there are four connecting rods and two gears (cranks), so it is referred to as a four-bar linkage; the slider at the end of the crank is replaced by a nylon rod on the gear, and the hollow groove rail passing through the connecting rod is driven by the gear to move along the radial direction of the connecting rod to drive the connecting rod to rotate. The sliders at the heads of the connecting rods on both sides are fixed on the guide rails to enable the two sides to move synchronously, and then the sliders are connected to the draw plate; the gears are driven by a stepper motor, and the driven gear transmission ratio is 1:1. The gears are fixed to the motor frame with the motor to ensure that the end of the motor shaft does not interfere with the movement of the connecting rod.
[0057] 2. Seeding module design.
[0058] 1. The overall structure of the seeding module.
[0059] like Figure 6 As shown, the seeding module can be divided into two parts. The upper part is the acrylic seed box 2, which will be sent to the symmetrical cylinders on both sides through the rotating rod according to the direction of the bud tip. The seeding gripper will grab the taro seedlings to be planted in the cylinders on both sides and send them to the top of the pit to be planted, and then release the four claws to complete the seeding work; the overall length, width and height are: 650mm*500mm*563mm.
[0060] 2. Design of seed box mechanism.
[0061] The four walls of the acrylic seed box 2 are fixed to the aluminum material by the first M6 screws 12, which ensures the stability during the actual operation of the machine; the taro seedlings entering the acrylic seed box 2 can roll into the central groove along the inclined wall, and the bottom of the central groove is a pointed arc mouth, which ensures that the taro seedlings will not directly enter the cylinders on both sides when falling, but will first phase in the center and wait for the rotating rod; the engineering drawing is shown in FIG. Figure 7 , Figure 8 and Fig. 9 As shown; after the small taro falls into the central groove, the back of the central groove slide 3 is fixed on the slider of the electric lead screw, and the lead screw stepper motor rotates to make the central groove slide move downward along the inside of the acrylic seed box 2 until it is tangent to the edges of the pipes on both sides, and the rotation direction of the rotating rod is controlled according to the direction of the bud tip; if the bud tip is facing left, that is, the rotating rod needs to rotate clockwise, and when it moves to the central groove, it pushes the taro seedling to move to the right and fall into the right tube, and finally keeps the bud tip facing upward and falls into the cylindrical seed placing gripper; if the bud tip is facing right, the rotating rod rotates counterclockwise, pushes the taro seedling to fall into the left tube, and is sent to the top of the pit to be planted by the seed placing gripper to fall in a manner with the bud tip facing upward; the rotating rod is driven by a stepper motor, and the recognition vision technology can be used to adjust the rotation direction according to the actual bud tip direction.
[0062] The seed placing gripper can be divided into two motion mechanisms: a rotating end and a cup-shaped gripper (seed cup 10); the front end of the seed placing gripper mechanism is a cup-shaped gripper, the rear end is fixed on the base, the rotating end is located in front of the fixed end, and is controlled by a steering gear 7.
[0063] The cup-shaped gripper of the seed placing mechanism adopts wire-driven movement; when the taro seedling falls from the seed placing box tube to the cup-shaped gripper, the end of the wire-driven paddle 5 is vertically downward, and the straight-line distance from the winding end to the cup-shaped winding hole of the four wires is the shortest. When the total length of the wire remains unchanged, the wire connected to the four fingers inside the gripper is longer, so that the four fingers are tightened to grab the taro; when the gripper arm rotates to the base limiter at the center, the gripper is already located above the soil pit to be placed, and at the same time, the rotatable end of the wire-driven paddle 5 comes into contact with the limiter, and the end head moves along the semi-cylindrical section of the limiter so that the head is no longer kept vertically downward, and the straight-line distance from the winding end to the cup-shaped winding hole becomes longer, so that the wire length of the four fingers in the cup becomes shorter, and the four fingers are opened, and the taro seedling naturally falls into the pit, completing the seed placing.
[0064] 3. Design of digging module.
[0065] 1. The overall structure of the digging module.
[0066] The main function of the hole digging module is to dig a hole that meets the size requirements of small taro planting under soil conditions of different hardness. At the same time, it can lift the dug soil when planting, and cover the soil back into the hole after planting to complete the pit filling work. The advantage of this design is that it can not only dig holes and sow seeds under different field conditions, but also realize the functions of digging holes and covering soil through the same module; the preliminary plan is to use a stepper motor to control the central worm to rotate and drive four meshing gears to rotate at a transmission ratio of 1:3, and the gears are then meshed with the racks on the shovels to drive the four shovels to move downward or upward along the track to complete the hole digging operation or the soil covering operation. However, adding transmission gears inside the mechanism not only makes assembly difficult, but also reduces the transmission efficiency through two transmissions, and causes insufficient downward pressure applied by the tip of the shovel when digging, which is easy to yield on hard soil, resulting in damage to the mechanism and failure to complete the hole digging task; such as Fig.10 As shown, the newly designed hole digging mechanism consists of four alloy digging shovels 24 with racks on the sides and a spherical worm 25 controlled by a DC motor. The entire hole digging mechanism is fixed on the conveyor sliders on both sides, that is, the synchronous belt slide assembly 22, and can move up and down with the sliders. Compared with the first version, it not only strengthens the structural strength of the four shovels, but also removes the gear with a transmission ratio of 1:3 that meshes with the worm, allowing the rack to directly mesh with the worm to improve the transmission efficiency and enhance the tip downward pressure applied to the soil surface when digging holes. The structure is lightweight and the assembly plan is optimized. At the same time, the electric push rod is no longer used as the rising mechanism, but a lead screw is used to ensure the stability of the rise.
[0067] The newly designed burrowing module not only has a more stable structural strength, but also uses sheet metal for chassis installation. Compared with the acrylic plate assembly solution, it is less likely to cause the burrowing mechanism to shake back and forth when it rises as a whole, causing the excavated soil to spill out. The maximum distance that the burrowing mechanism can descend (compared to the base of the burrowing module) is 200mm, and the maximum height that the mechanism can rise as a whole is 550mm, the travel of the conveyor belt. The overall size of the burrowing module (within the normal working range) is: 222mm*364mm*627mm.
[0068] 2. Design of digging module mechanism.
[0069] like Fig.11 As shown, the newly designed digging module is mainly controlled by a motor to rotate the spherical worm 25 inside the frame fixed on the conveyor slider, that is, the synchronous belt slide assembly 22, and at the same time, the inner racks of the four digging shovels 24 are all engaged with the spherical worm 25 and driven by the worm, and the transmission ratio is 1:1, that is, for every rotation of the spherical worm 25, the rack moves up or down one tooth number according to the rotation direction; each digging shovel 24 can be smoothly connected to the track on the frame by using chamfered hexagon socket counter-locking screws and adding isolation gaskets, and can descend or rise with the movement of the rack; the four acrylic brackets 23 are kept relatively fixed by the four-corner connectors and fixed to the slider by the connectors.
[0070] 3. The specific process of implementing the digging function is as follows.
[0071] The electronic control system issues a command to start digging the hole, the conveyor belt stepper motor rotates forward, and the entire frame descends with the conveyor belt slide. When it reaches the surface of the soil to be dug, the conveyor belt stops, and the motor controls the spherical worm 25 to start rotating, driving the four digging shovels 24 to descend along the circular arc track of the frame. At the same time, the four digging shovels 24 descend with the rack, and the tips of the shovel heads gradually close to complete the digging work.
[0072] After that, the four digging shovels 24 remain in a closed state, and the conveyor belt motor flips to drive the entire frame to rise. After reaching the specified height, the seeding module waits for the seeding gripper to send the taro seedlings to the top of the dug pit. After releasing the taro seedlings, the spherical worm 25 reverses to make the four shovels rise and gradually separate due to the rack drive. At this time, the excavated soil falls directly into the pit from above to complete the soil covering operation.
[0073] After a complete digging operation is completed, the conveyor motor and the spherical worm 25 move simultaneously to return the frame and the digging shovel 24 to the initial position.
[0074] The hole digging module designed by the present invention operates stably and efficiently, and the four-shovel mechanism can dig holes in soils of different hardnesses, and can stably rise while lifting the dug soil without soil loss; in particular, the innovative design of the spherical worm 25 and the rack transmission, the spherical structure ensures that it is tangent to the arc-shaped rack, and can better mesh without motion interference, thereby improving the transmission efficiency of the mechanism and increasing the downward pressure of the shovel head tip on the soil, so that the shape of the dug hole is stable, the position of each hole is accurate, and there is no soil collapse. At the same time, the shovel does not produce yield deformation due to large resistance, and can accurately put the soil back into the pit when covering the soil to complete the landfill of the taro seedlings, and the taro seedlings will not be exposed due to deviation in the covering soil position.
[0075] 4. Design of fertilization and irrigation module.
[0076] 1. Overall design of fertilization and irrigation module.
[0077] like Fig.12 As shown, the fertilization and irrigation mechanism can be divided into three parts: fertilizer box, water tank and feeder. The water tank and fertilizer box are directly fixed on the frame through aluminum profiles, and the feeder is connected to the lower end of the fertilizer box through a sheet metal motor frame. The overall dimensions of the fertilization mechanism and water tank are: 216mm*206mm*400mm, 290mm*130mm*240mm.
[0078] 2. Design of fertilization and irrigation mechanism.
[0079] The fertilization and irrigation mechanism is mainly divided into the fertilization mechanism and the irrigation mechanism. The irrigation mechanism is mainly composed of a water tank and a water pipe. The principle is relatively simple, but it will eventually be connected to a three-way interface with the output pipe of the fertilization mechanism, and then a DC motor diaphragm pump will be used to control the flow rate to achieve the fertilization and irrigation functions; the fertilizer box is above the fertilization mechanism, and the output port of the fertilizer box is connected to the feeder; the feeder can be compared to a 4-tooth gear, and between the two teeth is the delivery bin for each fertilization. The central axis of the feeder is connected to the output shaft of the stepper motor fixed on the motor frame through a coupling, and the stepper motor drives the feeder to rotate. Each rotation of 45° completes one feeding, and repeats this process over and over again. The design of the feeder not only ensures that the amount of fertilizer delivered each time is the same, but also allows the feeding to be stopped at any time. The output port of the feeder and the output end of the water pipe connected to the water tank are both connected to a three-way interface, and the output end of the three-way interface is connected to a DC motor diaphragm pump through a pipeline. The diaphragm pump can change the fluid flow rate by controlling the size of the suction force generated, and transport water and fertilizer. The output end of the pump is connected to the pipe, and ultimately the fertilizer and water can be directly transported to the pit after planting, realizing real-time and precise fertilization and irrigation functions.
[0080] 5. Lamination module design.
[0081] For taro crops such as small taro, mulching reduces soil moisture evaporation and also has the effect of storing water and conserving moisture. Under the protection of the mulch, the fertilizer applied to the soil will not be lost due to wind, sun or rain, and it also effectively controls the growth of weeds.
[0082] The film covering mechanism is mainly composed of rollers, triangular blades and a base. The rollers are connected to the aluminum profile of the vehicle body through sheet metal connectors, and can be adjusted according to the height of the vehicle bottom surface from the field to be covered, ensuring that the rollers can press the covered film closely against the soil surface. At the same time, the triangular blade of the film cutting mechanism is connected to the electric push rod, which can provide sufficient downward force to achieve automatic film cutting. Fig.13 shown.
[0083] The present invention is mainly composed of a seed box module, a seed placing module, a hole digging module, a fertilization and irrigation module and a film covering module; the overall three-dimensional diagram is as follows Fig.14 As shown; the digging module will face the digging work of soils with different hardness and height. In the field experiment of the first version of the digging mechanism, the use of gears with a transmission ratio of 3:1 reduced the transmission efficiency. When facing hard soil, some shovel heads showed bending due to yield strain or direct fracture from the rack due to excessive resistance; the newly designed digging mechanism has high stability; the cup-shaped gripper of the seed placement module has strengthened the ability of the robot arm to resist gravity rectangular deformation by adding a base.
[0084] The present invention adopts a modular design, and each function can be systematically coordinated and operated through the modular design when performing sowing work; if new functional modules need to be added, each module can be flexibly disassembled and assembled according to work needs, ensuring the lightness and professionalism of the robot when performing different tasks.
[0085] The present invention has integrated functions. In current actual agricultural activities, existing agricultural machinery has the disadvantages of single function, labor consumption, low intelligence and low operation precision. The present invention integrates all the functions required for small taro sowing and management on one vehicle, and each function has not only high operation precision and stable structure, but also high automation and coordination, so that the whole system can operate continuously and stably.
[0086] The present invention makes innovation in the transmission mechanism. In the hole digging mechanism, a transmission structure of a spherical worm 25 and an arc-shaped rack is designed. Only one motor needs to be controlled to drive the shovel to dig holes downward, and the soil covering work after seeding can be completed. The accuracy, stability and simplicity of the mechanism are guaranteed while the transmission efficiency is improved. At the same time, a line-driven cup-type seeding gripper is designed in the seeding structure. By adding a limiter to control the gripper to automatically grasp and release the taro seedlings, the electronic control layout is simplified while reflecting the cutting-edge design of the under-actuated gripper.
[0087] By adding advanced technologies such as intelligent, digital and 5G communication technology, the present invention can not only ensure the accuracy of sowing and management work, but also provide technical support for remote crop status detection and management; specifically, the present invention uses 5G technology, Beidou navigation technology and industrial Internet cloud platform technology; using 5G technology and Beidou centimeter-level precision positioning technology, Beidou positioning data is collected in real time, and uploaded to China Mobile Onenet cloud platform in real time through HTTP protocol, so that users can view the work location in real time on multiple platforms, not just GPS positioning data; also combined with the rapidly developing intelligent sensor technology, we can collect crop growth environment information and upload it to the cloud platform in real time. This work has adopted humidity and temperature sensors to monitor the vehicle environment in real time; the present invention is equipped with a camera system to regularly record the growth status of crops in the farmland, and at the same time uses the advanced neural network technology YOLOV8 architecture to train the recognition library of Luochuan taro suffering from pests and diseases. After the pictures are uploaded, they are compared and alarmed for plants with pests and diseases.
[0088] The above-mentioned embodiments only express several implementation methods of the present invention, and the descriptions thereof are relatively specific and detailed, but they cannot be understood as limiting the scope of the invention patent. It should be pointed out that, for ordinary technicians in this field, several variations and improvements can be made without departing from the concept of the present invention, and these all belong to the protection scope of the present invention. Therefore, the protection scope of the patent of the present invention shall be subject to the attached claims.
