Description

Technical Field

[0001] This invention relates to the field of desert greening engineering technology, specifically to a high-pressure water jet desert seedling planting system, which is particularly suitable for mechanized vegetation restoration operations in arid and semi-arid regions. Background Technology

[0002] Currently, the global desertification area has reached 36 million square kilometers, and is expanding at a rate of 50,000 to 70,000 square kilometers per year. Traditional desert afforestation methods face three major technical bottlenecks: low efficiency of manual planting, low irrigation water utilization, and a seedling survival rate generally below 30%. Existing mechanized planting equipment, while achieving integrated ditching and planting, has the following drawbacks: the low lateral water diffusion rate in sandy soil, resulting in low seedling survival rates, necessitates the development of a new type of desert afforestation equipment that integrates efficient planting, precise irrigation, and energy conservation. Summary of the Invention

[0003] In view of the problems and shortcomings of the existing technology, the present invention provides a high-pressure water jet desert seedling planting system.

[0004] The technical solution of this invention is as follows:

[0005] The high-pressure water jet desert seedling planting system consists of a planter mounted on a planting vehicle via a planting robotic arm, which includes a guide, a fence pipe support, and several fence water pipes connected in sequence.

[0006] The guide and the fence tube support are hollow tubular structures with the central hole coaxial. The top of the guide is provided with an outwardly expanding inlet, and the fence tube support is provided with a water inlet hole connected to the water supply system. The fence water pipes are arranged in a circular array at the bottom of the fence tube support, with the upper inlet connected to the fence tube support and the bottom providing a water outlet hole.

[0007] The water supply system includes a water storage tank, a water pump, and a high-pressure accumulator connected in sequence. The high-pressure accumulator is connected to the water inlet through a pipeline. The water supply system is used to supply water to the planter and regulate the flow rate.

[0008] A deadbolt is also connected to the fence tube support, which is used to open and close the center hole of the fence tube support.

[0009] The anti-lock device includes an anti-lock frame, a drive mechanism, and an anti-lock plate. The anti-lock frame is connected to the fence tube support, and the anti-lock plate controls the connection or disconnection between the central hole of the fence tube support and the guide through the drive mechanism.

[0010] The high-pressure water jet desert seedling planter also includes a support base, which is installed and supported on the outer ring of the circumferential array of grid water pipes, located at the lower end of the grid water pipes near the water outlet.

[0011] The guide includes an outwardly expanding tapered inlet and a connecting part coaxially connected to the center hole of the fence tube support.

[0012] The fence water pipe includes a water pipe and a nozzle. The water pipe is a long and thin pipe connected to the nozzle at the bottom. The upper side wall of the nozzle is provided with a wrench fastening plane, and the lower part is provided with a conical head. The bottom of the conical head is provided with a water outlet hole.

[0013] The water storage tank and water pump are integrated on the planting vehicle. The inlet of the water storage tank is also connected to a water receiving device, and the opening of the water receiving device faces upward.

[0014] The water supply system also includes a water truck with a self-drive chassis. A water tank and an adjustable water injection pipe assembly are connected to the self-drive chassis. The adjustable water injection pipe assembly is connected to the water tank through a water pump and consists of multiple sections of retractable and rotatable connecting pipes, used to inject water into the water receiving parts.

[0015] The adjustable water injection pipe assembly includes a first connecting pipe, a second connecting pipe, and a third connecting pipe;

[0016] The first connecting pipe adopts a right-angle bend, with its lower part being vertical and able to rotate freely, and its upper part being horizontal. Its outlet is connected to the inlet of the second connecting pipe. The second connecting pipe is horizontal and can automatically extend and retract. Its outlet is connected to the inlet of the third connecting pipe. The third connecting pipe is vertical and can automatically extend and retract. Its outlet is connected to a ferromagnetic water connector.

[0017] The water receiving fitting is equipped with an electromagnetic positioning component, and the ferromagnetic water connector is used to magnetically connect with the electromagnetic positioning component.

[0018] The ferromagnetic water connector is spherical with several water outlet holes on its wall.

[0019] The beneficial effects of this invention are:

[0020] High-pressure water jets create stable planting holes in the sand, avoiding the problems of sand loosening and hole collapse caused by traditional mechanical digging. The water jets simultaneously provide initial moisture to the seedlings, promoting root development. The ring-shaped array of water pipes creates a uniform water flow field, ensuring that the planting holes are regular in shape and consistent in depth. Compared to traditional manual digging methods, this significantly improves efficiency and water resource utilization, effectively solving the problems of low planting efficiency and severe water waste in desert areas.

[0021] The planting holes created by the high-pressure water flow allow the seedling roots to reach the moist sand layer directly. The locking device design prevents the water flow from floating the seedlings, ensuring full contact between the roots and the sand. The seedling survival rate can reach over 90%, a significant improvement compared to traditional methods.

[0022] The planter is operated automatically by a multi-degree-of-freedom robotic arm, in conjunction with an intelligent watering system from an irrigation truck, to automate the entire process of seedling placement, drilling, planting, and watering. This significantly reduces manual labor and is particularly suitable for large-scale afforestation projects in desert areas.

[0023] The water truck employs a multi-wheel independent suspension system and lidar navigation, enabling precise positioning and stable water injection in soft sand. The hydraulic adjustment function of the wheels allows the equipment to adapt to undulating terrain, ensuring stable operation in harsh environments. Attached Figure Description

[0033] The technical means adopted to achieve the intended purpose of the present invention will be further described below with reference to the accompanying drawings in the embodiments of the present invention.

[0034] Example 1

[0035] See Figure 1 A high-pressure water jet desert seedling planting system includes a planter 1 and a water supply system. The planter 1 includes a guide 11, a fence pipe support 12, and several fence water pipes 13 connected in sequence.

[0036] See Figure 1 The guide 11 and the fence tube support 12 are hollow tubular structures with their central holes coaxial. The top of the guide 11 has an outwardly expanding inlet for inserting seedlings into the planter 1 through the inlet. The fence tube support 12 has a water inlet 121 connected to the water supply system. The fence water pipes 13 are arranged in a circular array at the bottom of the fence tube support 12, and their upper inlets communicate with the fence tube support 12. See Figure 3 The fence water pipe 13 includes a water pipe and a nozzle 16. The water pipe is a long and thin pipe, and the nozzle 16 is connected to the bottom. The upper side wall of the nozzle 16 has a wrench fastening surface, and the lower part has a conical head with a water outlet hole at the bottom. The nozzle 16 and the water pipe can be detachably connected or integrally formed. It is preferred to adopt a detachable connection structure to facilitate the replacement of the nozzle 16.

[0037] The guide 11 includes an outwardly expanding conical inlet and a connecting part coaxially connected to the central hole of the fence pipe support 12. The conical inlet ensures that the seedling falls vertically into the central hole of the connecting part, then into the central hole of the fence pipe support 12, and then downwards through the central hole of the fence pipe support 12 into a cylindrical channel formed by the fence water pipe 13, and finally downwards from the channel outlet into the planting hole. The fence pipe support 12 is connected to the water supply system through the water inlet 121. Water enters the fence water pipe 13 through the fence pipe support 12, and then flows out from the water outlet at the bottom of the fence water pipe 13, forming a high-pressure water flow. The high-pressure water flow impacts downwards to form the planting hole, driving the roots of the seedling deep into the sand. Water is injected at the same time as planting, which greatly reduces the time required to plant seedlings and improves the survival rate.

[0038] See Figure 5 The water supply system includes a water storage tank 32, a water pump 33, and a high-pressure accumulator 34 connected in sequence. The inlet of the water pump 33 is connected to the outlet of the water storage tank 32, and the outlet is connected to the high-pressure accumulator 34 through a pipeline. The high-pressure accumulator is connected to the water inlet 121 on the fence pipe support 12 through a pipeline. The flow rate of the water supply is automatically controlled by a valve installed on the pipeline.

[0039] See Figure 8In use, the seedling is first placed in the guide 11, and the water supply system is activated to provide high-pressure water to the planter 1. The water flows through the inlet 121 of the fence pipe support 12, through the fence water pipe 13, and forms a high-pressure water flow from the outlet at the bottom of the fence water pipe 13. The high-pressure water flow impacts the sand to form planting holes. At the same time, the planter 1 sinks as the planting hole depth increases. After reaching the appropriate depth, the planter 1 is lifted up, and the roots of the seedling are buried in the mud and sand, thus completing the planting and watering of the seedling. Then, the planting of the next seedling is carried out.

[0040] See Figure 2 The fence tube support 12 is also connected to a locking device 14, which is used to open and close the center hole of the fence tube support 12. When placing the seedling into the planter 1, the locking device 14 is opened, connecting the center hole on the fence tube support 12 with the guide 11, so that the seedling falls smoothly into the planting hole at the bottom; when the planter 1 and the seedling sink to a suitable depth, the locking device 14 is closed, blocking the hole on the fence tube support 12, preventing the high-pressure water flow from pushing the planted seedling upwards and affecting the root fixation, and preventing the water below from floating the seedling and affecting the root fixation of the seedling.

[0041] The locking device 14 includes a locking frame 141, a drive mechanism, and a locking plate 143. The locking frame 141 is connected to the fence tube support 12. The locking plate 143 is driven by the drive mechanism to control the connection or disconnection between the center hole of the fence tube support 12 and the guide 11. The drive mechanism uses a motor 142 and a screw. The screw is threaded into one end of the locking plate 143, and the other end of the locking plate 143 extends into the center hole inside the fence tube support 12. When the motor 142 rotates, it drives the locking plate 143 to move relative to the locking frame 141. When it moves inward, it blocks the center hole of the fence tube support 12; when it moves outward, it opens the center hole of the fence tube support 12. When the seedling is placed on the guide 11, the locking plate 143 opens; when the seedling sinks to the target depth, the locking plate 143 closes.

[0042] See Figure 3 To improve the stability of the fence water pipe 13 and prevent it from spreading out during drilling, the high-pressure water jet desert seedling planter 1 and water supply system also include a support base 15, which is installed and supported on the outer ring of the circumferentially arrayed fence water pipe 13, located at the lower end of the fence water pipe 13 near the water outlet.

[0043] This planter can be used for planting manually, or like... Figure 4 or Figure 5 The planter 1 is then mounted on the planting cart 3 via the planting robotic arm 2. The planting robotic arm is a multi-degree-of-freedom robotic arm, mounted on the planting cart 3 via a flange. The water tank 32 and water pump 33 are integrated on the planting cart 3. Automated planting is achieved through the planting robotic arm 2, further improving planting efficiency compared to manual planting methods.

[0044] To further enhance automation, the planting vehicle includes a self-drive chassis, seedling boxes, a conveying mechanism, a gripping robotic arm, and a sizing robotic arm. The seedling boxes have a through-type structure for storing seedlings to be planted. The conveying mechanism includes a first conveying mechanism and a second conveying mechanism. The first conveying mechanism is located at the bottom of the seedling box and transports the seedlings in sections downstream. The gripping robotic arm is mounted above the conveying mechanism and is responsible for gripping individual seedlings and transferring them to the second conveying mechanism. The sizing robotic arm grips seedlings from the second conveying mechanism and transfers them to the high-pressure water jet planter on the planting robotic arm.

[0045] Example 2

[0046] See Figure 5 The main differences between this embodiment and Embodiment 1 are as follows:

[0047] The inlet of the water storage tank 32 is also connected to the water receiving component 31, and the opening of the water receiving component 31 faces upward, and an electromagnetic positioning component 311 is provided inside.

[0048] The water supply system also includes a water truck 4, used to fill the water storage tank. See Figure 6 The water truck 4 has a self-drive chassis, on which a water tank and an adjustable water injection pipe assembly are connected. The adjustable water injection pipe assembly is connected to the water tank through a water pump 33 and is used to inject water into the water receiving part 31.

[0049] See Figure 6 The adjustable water injection pipe assembly includes a first connecting pipe 41, a second connecting pipe 42, and a third connecting pipe 43. The first connecting pipe 41 is a right-angle bend, with its lower part vertical and capable of free rotation, and its upper part horizontal. Its outlet connects to the inlet of the second connecting pipe 42. The second connecting pipe 42 is horizontal and capable of automatic horizontal expansion and contraction. Its outlet connects to the inlet of the third connecting pipe 43. The third connecting pipe 43 is vertical and capable of automatic vertical expansion and contraction. Its outlet connects to a ferromagnetic water connector 44. (See also...) Figure 7 The magnetic water connector is used to magnetically connect with the electromagnetic positioning element 311 during water injection. The second connecting pipe 42 and the third connecting pipe 43 are automatically extended and retracted by a telescopic mechanism. This adjusts the position of the ferromagnetic water connector 44 so that it can magnetically connect with the electromagnetic positioning element 311, thereby ensuring that the water truck 4 can accurately inject water into the water receiving part 31 and prevent water from spilling outside the water receiving part 31, thus wasting water resources. Specifically, during the process of the third connecting pipe 43 being electrically extended downwards to the water receiving part 31, in order to avoid shaking caused by the vehicle running, the water connector 44 is thrown outside the water receiving part 31, and the electromagnetic positioning element 311 is energized to generate magnetism, attracting the magnetizable ferromagnetic water connector into the water receiving part 31; when the water truck runs out and a new truck needs to be replaced, the electromagnetic positioning element 311 loses its electromagnetic property, and the third connecting pipe retracts electrically. The telescopic mechanism is driven by a lead screw or hydraulic cylinder by a motor 142.

[0050] See Figure 6 The ferromagnetic water connector 44 is spherical, with several water outlet holes on its wall. The water outlet holes can be round holes or arc-shaped elongated holes.

[0051] In use, the electromagnetic positioning component is energized to generate magnetism. The first connecting pipe 41 then rotates outward, positioning the second connecting pipe 42 outside the water tank. The length of the second connecting pipe 42 is then adjusted until the third connecting pipe 43 is positioned above the water receiving component 31. The length of the third connecting pipe 43 is then adjusted until the ferromagnetic water connector 44 connects to the electromagnetic positioning component 311. The water pump 33 is then started to fill the water receiving component 31 with water. After filling, the water pump 33 stops, and the electromagnetic positioning component 311 separates from the water connector. The lengths of the third connecting pipe 43 and the second connecting pipe 42 are then adjusted to their shortest possible lengths, and the first connecting pipe 41 is rotated to move the third connecting pipe 43 outside the water receiving component 31. Finally, the water truck 4 drives away until the next filling.

[0052] See Figure 6 The self-propelled chassis includes a chassis body, control system, power module, steering drive device, hydraulic rods, and wheels. The control system is located at the bottom of the chassis body, while the power module is mounted on the chassis. The control system integrates a main control unit, sensor interfaces, and communication modules, and is responsible for coordinating the operation of the entire irrigation truck 4. The power module adopts a redundant backup design, with at least two independent power supply units.

[0053] Two rows of wheels are symmetrically arranged along the length of the chassis. Each row includes several drive wheels and driven wheels, with the drive and driven wheels staggered. This multi-wheel design significantly improves traversability on soft sand. Each wheel is connected to the chassis via a steering drive unit, which uses a high-torque direct-drive motor 142, allowing direct steering adjustment within a 360° range. A hydraulic rod is mounted on the wheel support below the steering drive unit. The hydraulic system allows independent adjustment of the ground clearance of each wheel, ensuring all wheels maintain contact with the uneven sand while maintaining consistent force on each wheel. The wheels are hinged to the lower part of the hydraulic rod, providing rotational freedom about a horizontal axis parallel to the vehicle's length. This enhances the chassis's passability, especially allowing the wheels to deflect freely when encountering obstacles.

[0054] A high-precision lidar is installed at the front and rear of the chassis, which can detect the surrounding environment in real time and perform accurate positioning. The positioning data is fed back to the control system for navigation and path planning.

[0055] The remaining structure is the same as in Example 1, and will not be described again here.

[0056] The above description represents a preferred embodiment of the present invention. However, the present invention is not limited to the above embodiments and examples. Within the scope of knowledge possessed by those skilled in the art, all variations, equivalent substitutions, improvements, etc., made without departing from the concept of the present invention should be included within the protection scope of the present invention.
