Description

Technical Field

[0001] This invention relates to the field of planting and cultivation technology, specifically to a water-retaining and root-stabilizing cultivation device for greening plants in sandy areas. Background Technology

[0002] When carrying out vegetation restoration and sand fixation projects in sandy areas, traditional manual planting methods are inefficient, costly, and difficult to implement on a large scale in vast sandy areas. To improve the efficiency of greening sandy areas, various mechanized cultivation equipment has emerged in the agricultural planting field. These devices are usually based on tractors or special vehicle platforms and can achieve continuous operations such as ditching, planting seedlings, and covering with soil, which improves the speed of operation to a certain extent.

[0003] Existing cultivation equipment, especially double-row or multi-row planting equipment designed to improve efficiency, typically has a fixed spacing between its planting units (such as furrow openers or planters). When encountering obstacles located between two planting rows during operation, the entire machine often needs to be rerouted or stopped for manual clearing, severely disrupting the uniformity of planting row spacing and the continuity of operation.

[0004] Some agricultural machines with obstacle avoidance functions have already appeared in the prior art. For example, CN213880814U discloses a weeding device with contour-following obstacle avoidance function, which detects obstacles through sensors and uses hydraulic cylinders to drive the weeding unit to move laterally or swing to avoid obstacles.

[0005] However, such designs are typically designed for obstacle avoidance by individual tools (such as weeders) near fixed work trajectories. Their adjustment freedom is relatively limited, and their core purpose is to protect the machine itself rather than maintain the trajectory and quality of continuous operation. Simply transplanting or arranging such single-degree-of-freedom obstacle avoidance mechanisms in parallel with double-row or multi-row continuous planting equipment still struggles to resolve the conflict between the overall travel path of the equipment and the planned row spacing when encountering obstacles between rows. It fails to ensure the continuity of multi-row planting, uniform row spacing, and coordinated movement of planting units while avoiding obstacles. Therefore, designing a dedicated device that enables planting units to flexibly and collaboratively adapt to complex terrain, thereby achieving uninterrupted and efficient greening, under the specific working mode of multi-row continuous planting, has become a pressing technical problem in this field. Summary of the Invention

[0006] This invention provides a water-retaining and root-stabilizing cultivation device for greening plants in sandy areas, which has the beneficial effects of integrating double-row continuous planting and adaptive terrain obstacle avoidance functions, and solves the problems mentioned in the background art.

As the sand vehicle travels along the sand, green plants are cultivated through the two planting mechanisms. When the sand vehicle passes through obstacle terrain, the relative distance between the two planting mechanisms is adjusted by the first adjustment mechanism to avoid obstacles.

[0010] As an optional solution of the water-retaining and root-fixing cultivation device for sandy land greening described in this invention, the base is further provided with a second adjustment mechanism, which is used to adjust the angle of the two planting mechanisms relative to the chassis.

[0011] As an optional embodiment of the water-retaining and root-fixing cultivation device for sandy land vegetation described in this invention, the second adjustment mechanism includes a second cylinder, with a second connecting shaft and a third connecting shaft fixedly installed at both ends of the second cylinder, the second connecting shaft being rotatably connected to the chassis, and the third connecting shaft being rotatably connected to the mounting base.

[0012] As an optional solution of the water-retaining and root-stabilizing cultivation device for sandy land vegetation described in this invention, the planting mechanism includes a seedling box and a grass-inserting component. The seedling box is fixedly installed on the sliding base and is inclined to hold the vegetation. The grass-inserting component includes an L-shaped fork, which is used to pick up the vegetation from the seedling box and plant it in the sandy land.

[0013] As an optional solution of the water-retaining and root-fixing cultivation device for sandy land vegetation described in this invention, the grass-inserting assembly further includes a first rotating rod, a first connecting rod, and a first connecting arm. The first rotating rod is rotatably mounted on the sliding seat, and the first connecting rod is fixedly installed at the tail end of the L-shaped fork. One end of the first connecting arm is fixedly mounted on the first rotating rod, and the other end of the first connecting arm is rotatably mounted on the first connecting rod.

[0014] As an optional solution of the water-retaining and root-fixing cultivation device for sandy land greening described in this invention, the grass insertion assembly further includes a second rotating rod, a second connecting arm and a third connecting arm, the second rotating rod is rotatably mounted on the slide, and the second connecting rod is fixedly installed in the middle of the L-shaped fork; One end of the second connecting arm is fixedly mounted on the second rotating rod, and the other end of the second connecting arm is rotatably mounted on the second connecting rod. The two ends of the third connecting arm are respectively rotatably mounted on the first connecting rod and the second connecting rod.

[0015] As an optional embodiment of the water-retaining and root-fixing cultivation device for sandy land vegetation described in this invention, the planting mechanism further includes a feeding component for conveying the vegetation on the seedling box. The feeding component includes a first conveyor roller and a second conveyor roller rotatably mounted on the seedling box, and a conveyor belt is drivingly connected to the first conveyor roller and the second conveyor roller.

[0016] As an optional embodiment of the water-retaining and root-fixing cultivation device for sandy land vegetation described in this invention, wherein: a first motor and a second motor are fixedly installed on the slide block, the output shaft of the first motor is fixedly connected to the second rotating rod, and the output shaft of the second motor is fixedly connected to the second conveying roller.

[0017] The present invention has the following beneficial effects: 1. This water-retaining and root-stabilizing cultivation device for sandy land vegetation achieves a balance between efficient continuous operation and intelligent obstacle avoidance. The device features a sliding and rotating mounting base under the chassis of the sand-planting vehicle, upon which two independent planting mechanisms are symmetrically arranged. This allows the equipment to cultivate two rows of vegetation in parallel, significantly improving operational efficiency. The core innovation lies in the ability of a first adjustment mechanism to drive two sliding blocks to slide towards or away from each other along a second arc-shaped groove when encountering obstacles. This allows for quick and flexible adjustment of the lateral spacing between the two planting mechanisms, avoiding obstacles between rows without requiring the entire vehicle to detour, thus ensuring continuous operation and controllable row spacing.

[0018] 2. This water-retaining and root-stabilizing cultivation device for sandy land vegetation enhances its overall adaptability to complex terrain. In addition to lateral spacing adjustment, the device is equipped with a second adjustment mechanism consisting of a second cylinder, a second connecting shaft, and a third connecting shaft. This mechanism allows the entire mounting base to rotate within the first arc-shaped groove of the chassis, using its slide rod as an axis. When an obstacle is located on one side of the travel path, the second adjustment mechanism can be controlled collaboratively or independently to deflect both planting structures by an angle, minimizing path deviation to avoid the obstacle. This dual adjustment mechanism of spacing and angle significantly enhances the device's passability and adaptability in sandy environments filled with irregular obstacles.

[0019] 3. This water-retaining and root-stabilizing cultivation device for sandy land vegetation achieves dual-degree-of-freedom cooperative adaptive obstacle avoidance based on a specific mechanical structure. Existing obstacle avoidance solutions often rely on single-dimensional linear extension or simple oscillation, which have limited adjustment capabilities when dealing with chaotic and irregular obstacles in sandy terrain. This invention constructs a composite motion platform with dual degrees of freedom—lateral spacing adjustment and overall angle deflection—through a unique combination of a rotating joint consisting of a "sliding rod-first arc-shaped groove" and a sliding joint consisting of a "sliding seat-second arc-shaped groove." The first and second adjustment mechanisms do not work in isolation but can coordinate their actions based on obstacle information, dynamically planning the optimal obstacle avoidance path (such as only lateral separation, only angle deflection, or a combination of both), thereby achieving obstacle avoidance with minimal operational path deviation. This deeply integrated mechanical design and control logic ensures efficient and smooth connection between obstacle avoidance actions and continuous planting operations in complex terrain, fundamentally solving the technical problem of fixed-row or multi-row equipment being forced to frequently detour or interrupt operations in sandy environments.

[0027] The technical solutions of the embodiments of the present invention will be clearly and completely described below with reference to the accompanying drawings. Obviously, the described embodiments are only some embodiments of the present invention, and not all embodiments. Based on the embodiments of the present invention, all other embodiments obtained by those skilled in the art without creative effort are within the scope of protection of the present invention.

[0028] Example 1, please refer to Figures 1-6 A water-retaining and root-stabilizing cultivation device for green plants in sandy areas includes a sand-carrying vehicle 1, a chassis 2 fixedly installed on the bottom of the sand-carrying vehicle 1, and a mounting seat 3 slidably installed on the bottom of the chassis 2.

[0029] The mounting base 3 is provided with a first adjustment mechanism, which includes two slide rods 4, two first arc-shaped grooves 5, two slide blocks 6, and two second arc-shaped grooves 7.

[0030] Two sliding rods 4 are fixedly installed on the mounting base 3. Two first arc-shaped grooves 5 are symmetrically opened on the base 2. The centers of the two first arc-shaped grooves 5 are both located on the central axis of the mounting base 3. The two sliding rods 4 are slidably installed in the two first arc-shaped grooves 5 respectively. Two second arc-shaped grooves 7 are symmetrically opened on the mounting base 3. Two sliding blocks 6 are slidably installed in the two second arc-shaped grooves 7 respectively. Planting mechanisms are installed on both sliding blocks 6.

[0031] As the sand vehicle 1 travels along the sand, green plants are cultivated through two planting mechanisms. When the sand vehicle 1 passes through obstacle terrain, the relative distance between the two planting mechanisms is adjusted by the first adjustment mechanism to avoid obstacles.

[0032] A first cylinder 8 is fixedly mounted on the mounting base 3. The first cylinder 8 is distributed along the central axis of the mounting base 3. A first connecting shaft 9 is fixedly mounted on the piston rod of the first cylinder 8.

[0033] The first adjustment mechanism also includes two connecting plates 10. One end of each connecting plate 10 is rotatably mounted on the first connecting shaft 9, and the other end of each connecting plate 10 is rotatably mounted on two slide blocks 6.

[0034] In this embodiment: To achieve multi-row operation, existing mechanized planting equipment often adopts a rigid layout with fixed spacing for its planting units, or makes limited adjustments in a single dimension (such as only horizontal or only vertical). When encountering randomly distributed obstacles in sandy areas, this type of design often faces a dilemma: either the entire vehicle is forced to detour, disrupting the work rhythm and damaging the uniformity of row spacing; or it risks passing through, resulting in damage to the equipment or a decrease in planting quality.

[0035] The starting point of this invention is to abandon the obstacle avoidance approach of "fixed" or "single degree of freedom" and instead construct a mechanical platform with two adjustable degrees of freedom and interconnected motion trajectories. Its innovation is not simply to juxtapose known linear telescopic mechanisms and rotational mechanisms, but rather to achieve a more intelligent obstacle avoidance strategy that is more in line with the actual working conditions of sandy terrain through specific geometric constraints and motion coupling relationships.

[0036] Specifically, the sand-driving vehicle 1 can be a remotely controlled vehicle, facilitating operation in sandy environments. A mounting base 3 slides onto the chassis 2 of the sand-driving vehicle 1. A double-row planting mode is selected for water-retaining and root-stabilizing cultivation of greenery on the sand, and it also has obstacle avoidance capabilities. The positions of the two planting mechanisms on the mounting base 3 are not fixed. When encountering obstacles such as stones on the ground, the positions of the two planting mechanisms can be adjusted through a first adjustment mechanism, increasing the relative distance between them, thus helping the sand-driving vehicle 1 avoid obstacles when it passes over them.

[0037] Specifically, if the obstacle is in the direction of travel of the two planting units and is located in the middle of the two planting units, the obstacle can be avoided by moving the two planting units in opposite directions.

[0038] Specifically, when the central axis of the mounting base 3 is horizontal, the two implantation mechanisms are symmetrically positioned based on the mounting base 3, with the first cylinder 8 mounted on the mounting base 3. When the piston rod of the first cylinder 8 moves to the left, since the lengths of the two connecting plates 10 are fixed, and the sliding block 6 slides in an arc along the second arc groove 7, it has a limiting effect, causing the two sliding blocks 6 to slide to the left along the two second arc grooves 7 respectively. This increases the relative distance between the two implantation mechanisms.

[0039] It should be further explained that the cultivation of vegetation in sandy areas achieves "water retention and root strengthening." This function is not achieved through a single additional component, but rather through a combination of a systematic operation of the entire device and specific planting methods, specifically manifested in the following aspects: The water-retaining design of the planting process, specifically the L-shaped fork 15 in the planting assembly, is designed to minimize disturbance to the plant's root ball. When retrieving a seedling from the seedling box 14, the curved structure of the L-shaped fork 15 supports the bottom of the plant's root ball, and combined with the gentle push of the conveyor belt 25, ensures stable seedling retrieval. During the insertion of the plant into the sandy soil, the linkage mechanism (first rotating rod 16, second rotating rod 19, first connecting arm 18, second connecting arm 21, third connecting arm 22, etc.) drives the L-shaped fork 15 to move approximately vertically in the soil insertion section, allowing the plant to be planted vertically and stably into the sand, avoiding root damage and insufficient soil covering caused by oblique insertion. Vertical deep planting helps the roots contact the deep sandy soil, initially achieving "root stabilization."

[0040] In this invention, the seedlings placed in the seedling box 14 are pre-treated rootstock seedlings containing water-retaining agents and nutrient substrates. This is a conventional pretreatment technique in the field of sandy soil cultivation. The device, while in motion, implants these seedlings with "water-retaining and root-strengthening" potential into the sandy soil in an optimal physical posture (vertical) with minimal root disturbance. After implantation, the wheels of the sand-carrying vehicle 1 or a specially equipped lightweight compaction roller (a common auxiliary function of sandy soil operation vehicles, not shown in the figure but common knowledge to those skilled in the art) can lightly compact the planting point, ensuring close contact between the rootstock and the surrounding sand, reducing water evaporation channels, thereby achieving the final effects of "water retention" and "root strengthening." Therefore, "water retention and root strengthening" is a direct result and inherent attribute of the operation output of this cultivation device.

[0041] Example 2, please refer to Figures 2-6 The base 2 is also equipped with a second adjustment mechanism, which is used to adjust the angle of the two planting mechanisms relative to the chassis 2.

[0042] The second adjustment mechanism includes a second cylinder 11, with a second connecting shaft 12 and a third connecting shaft 13 fixedly installed at both ends of the second cylinder 11. The second connecting shaft 12 is rotatably connected to the chassis 2, and the third connecting shaft 13 is rotatably connected to the mounting base 3.

[0043] In this embodiment: considering other situations of obstacle distribution, that is, when the obstacle is in the travel path of one of the planting units, if the relative distance between the two planting units is still increased to avoid the obstacle, the distance between the two planting units will be too large, resulting in uneven distribution of green plants.

[0044] Therefore, in order to avoid obstacles to the minimum, the relative distance between the two planting mechanisms can be increased according to the specific situation, and the mounting base 3 can be rotated clockwise by a certain angle so that the two planting mechanisms are no longer horizontal to the left and right, but are distributed in a diagonal line.

[0045] If the obstacle is closer to the left, the relative distance between the two planting mechanisms can be avoided by rotating the mounting base 3 counterclockwise by a certain angle, instead of increasing the distance between the two planting mechanisms.

[0046] Specifically, the mounting base 3 is not fixed to the lower end of the chassis 2. Two sliding rods 4 are symmetrically mounted on the mounting base 3, and slide within two first arc-shaped grooves symmetrically opened at the lower end of the chassis 2. The two first arc-shaped grooves 5 are also arc-shaped grooves based on the central axis.

[0047] The second connecting shaft 12 is horizontally rotatably mounted on the lower end of the chassis 2, and the third connecting shaft 13 is also horizontally rotatably mounted on the side of the mounting base 3. By extending the piston rod of the second cylinder 11, the mounting base 3 can be pushed to rotate clockwise; by shortening the piston rod of the second cylinder 11, the mounting base 3 can be pushed to rotate counterclockwise.

[0048] As a conventional existing technology, sand-driving vehicles 1 are typically equipped with terrain perception modules, such as ultrasonic sensors, lidar, or vision cameras (all existing mature components) installed at the front of the vehicle or the front of the chassis 2. These sensors continuously scan the sand surface in front of and to the sides of the vehicle, identifying the height, outline, and relative position of obstacles such as protruding rocks and shrub stumps. Sensor data is transmitted to the onboard controller of the sand-driving vehicle 1. The controller has a built-in algorithm that calculates and predicts the travel trajectories of the two planting mechanisms (specifically, the expected entry points of the L-shaped forks 15) in real time. When the predicted trajectory conflicts with the detected obstacle position, the controller determines that an obstacle has been encountered and generates corresponding adjustment commands. This automated "perception-decision-execution" process is widely used in the field of agricultural robots. By applying the output of this process to the first and second adjustment mechanisms, intelligent obstacle avoidance planting is achieved.

[0049] The actions of the first and second adjustment mechanisms are not fixed in terms of priority; rather, the onboard controller makes dynamic decisions based on real-time obstacle information. They can operate independently or in coordination, exhibiting high flexibility and adaptability. The decision-making logic is as follows: Independent action scenes: Prioritize activation of the first adjustment mechanism: When the sensor detects that the obstacle is mainly located between the expected planting points of the two planting mechanisms (L-shaped forks 15), and the width of the obstacle is less than the maximum adjustable distance between the two slides 6 in the second arc-shaped groove 7, the controller prioritizes activating only the first adjustment mechanism. This means controlling the first cylinder 8 to move, driving the two slides 6 to move in opposite directions via the connecting plate 10, directly increasing the lateral distance between the two L-shaped forks 15, thus clearing the obstacle. At this time, the angle of the mounting base 3 remains unchanged.

[0050] Prioritize activation of the second adjustment mechanism: When an obstacle is biased to one side, roughly in front of the travel of one of the planting mechanisms, and the obstacle is not wide, the controller prioritizes activating only the second adjustment mechanism. This involves controlling the extension and retraction of the second cylinder 11, pushing the mounting base 3 to rotate within the first arc-shaped groove 5 via the slide rod 4, thereby changing the overall trajectory of both planting mechanisms, causing them to simultaneously avoid the obstacle as if "twisting." At this time, the distance between the two L-shaped forks 15 remains unchanged.

[0051] Collaborative action scenarios: When encountering large or uniquely positioned obstacles, two mechanisms may need to operate simultaneously to achieve optimal obstacle avoidance. For example, a large obstacle may partially obscure the middle and extend to one side. In this case, the controller will send control signals to the first cylinder 8 and the second cylinder 11 simultaneously or nearly simultaneously. From a mechanical response speed perspective, the initial response of the first adjustment mechanism (linear motion) may be slightly faster, but the two quickly enter a cooperative working state. By changing the spacing through the first adjustment mechanism and changing the angle through the second adjustment mechanism, the final positions of the two mechanisms can be flexibly adjusted to any desired position, thus successfully planning an obstacle avoidance path in complex terrain. There is no fixed "starting priority"; their actions are parallel and complementary.

[0052] Example 3, please refer to Figures 2-6 The planting mechanism includes a seedling box 14 and a grass-planting component. The seedling box 14 is fixedly installed on the slide 6 and is tilted to hold green plants. The grass-planting component includes an L-shaped fork 15, which is used to pick up green plants from the seedling box 14 and plant them in the sand.

[0053] The grass-planting assembly also includes a first rotating rod 16, a first connecting rod 17, and a first connecting arm 18. The first rotating rod 16 is rotatably mounted on the slide block 6, and the first connecting rod 17 is fixedly installed on the tail end of the L-shaped fork 15.

[0054] One end of the first connecting arm 18 is fixedly mounted on the first rotating rod 16, and the other end of the first connecting arm 18 is rotatably mounted on the first connecting rod 17.

[0055] The grass-planting assembly also includes a second rotating rod 19, a second connecting arm 21, and a third connecting arm 22. The second rotating rod 19 is rotatably mounted on the slide block 6, and the second connecting rod 20 is fixedly installed in the middle of the L-shaped fork 15.

[0056] One end of the second connecting arm 21 is fixedly installed on the second rotating rod 19, and the other end of the second connecting arm 21 is rotatably installed on the second connecting rod 20. The two ends of the third connecting arm 22 are rotatably installed on the first connecting rod 17 and the second connecting rod 20, respectively.

[0057] The planting mechanism also includes a feeding assembly for conveying the green plants on the seedling box 14. The feeding assembly includes a first conveyor roller 23 and a second conveyor roller 24 that are rotatably mounted on the seedling box 14. A conveyor belt 25 is drivenly connected to the first conveyor roller 23 and the second conveyor roller 24.

[0058] A first motor 26 and a second motor 27 are fixedly installed on the slide block 6. The output shaft of the first motor 26 is fixedly connected to the second rotating rod 19, and the output shaft of the second motor 27 is fixedly connected to the second conveying roller 24.

[0059] In this embodiment: the seedling box 14 can store a large number of green plants. Its specific structure can be referred to the existing rice transplanter and will not be described in detail. The seedling box 14 is equipped with a feeding component to assist the green plants in tilting and descending. The second motor 27 drives the second conveyor roller 24 to rotate clockwise, so that the first conveyor roller 23 and the conveyor belt 25 run clockwise. The conveyor belt 25 transports the green plants in the seedling box 14 downwards in a circular manner.

[0060] The grass-planting assembly is a linkage mechanism that performs eccentric motion. First, the first motor 26 drives the second rotating rod 19 to rotate counterclockwise, which in turn drives the second connecting arm 21 and the second connecting rod 20 to perform counterclockwise circular motion. The second connecting rod 20 then causes the L-shaped fork 15 to tend to perform circular motion. Simultaneously, because the first connecting rod 17 is limited by the first rotating rod 16 under the connection of the first connecting arm 18, the L-shaped fork 15 ultimately performs eccentric counterclockwise motion. Figure 3 For example, when the L-shaped fork 15 moves counterclockwise from the upper point to the left point, its head contacts the straw on the seedling box 14 at an angle. When the L-shaped fork 15 moves counterclockwise from the left point to the lower point, its head carries the plant and inserts it into the ground in a nearly vertical direction. The planting mechanism, as the basic structure of the rice transplanter, is existing technology, and the specific movement principle of the L-shaped fork 15 will not be elaborated upon.

[0062] The above description is only a preferred embodiment of the present invention. It should be noted that for those skilled in the art, several improvements and modifications can be made without departing from the technical principles of the present invention, and these improvements and modifications should also be considered within the scope of protection of the present invention.
