Description

Technical Field

[0001] This invention relates to the field of lunar resource acquisition technology, specifically a single-motor multi-functional shovel-type shovel. Background Technology

[0002] Currently, lunar sampling tools mainly fall into four categories: rotary impact drills, mechanical shovels, pneumatic samplers, and composite sampling systems, each suitable for different sampling scenarios and mission requirements.

[0003] Rotary percussion drills use an external auger drill rod with an internal soft bag (such as Kevlar fiber) to break up lunar soil and collect samples through a combination of rotation and impact, reaching depths of 2–3 meters. Their advantage lies in obtaining deep, undisturbed samples, but they suffer from severe drill wear, high power consumption (approximately 200W), and susceptibility to contamination during sample transfer. NASA's latest TRIDENT drilling system adds in-situ volatile analysis capabilities, but still faces limitations such as complex mechanism and significant weight (approximately 20 kg).

[0004] Mechanical shovels include adjustable-angle shovels, petal-shaped grippers, and clamshell excavators. These tools have relatively simple structures and can flexibly collect loose lunar regolith and small rocks from the surface. However, these sampling tools suffer from limited functionality and adaptability: traditional sampling shovels only have a shovel function and require subsequent equipment for sample processing; the complex terrain of the lunar surface leads to low sample collection efficiency; and existing equipment lacks the ability to classify samples of different particle sizes.

[0005] Pneumatic samplers are an emerging technology in recent years, such as the Lunar PlanetVac (LPV) developed by Honeybee Robotics and the TAGSAM device validated by the OSIRIS-REx mission. The former uses compressed gas to impact lunar soil and collect samples through negative pressure, while the latter uses high-pressure gas perturbation combined with a valve closure principle. Pneumatic sampling has significant advantages such as high speed (on the order of seconds), low power consumption, and lightweight structure, but the sampling depth is extremely shallow (<5 cm) and it is sensitive to physical parameters such as lunar soil particle size and moisture content, thus limiting its applicability.

[0006] The composite sampling system integrates drilling and shoveling functions, enabling multi-point operation via a robotic arm. While this system expands the sampling range to some extent, it still employs a simple modular design, resulting in independent control of each module, insufficient coordination, and high redundancy in the overall system. Summary of the Invention

[0007] To address the problems of mechanical shovels, such as limited shovel function, low efficiency in complex terrain, and lack of ability to grade samples of different particle sizes, this invention proposes a single-motor, multi-functional shovel-type picking shovel. This invention uses a vibration drive component to shake off lunar dust from lunar rocks, increasing sample purity. Furthermore, the rotation of the robotic arm, combined with the structural design of the sample picking component, allows for the smooth transfer of the target sample to other units.

[0008] This invention proposes a single-motor multi-functional shovel-type pickup shovel, which specifically includes a sample pickup component, a rotary shaft, a vibration drive component, a housing, and a rotary drive component. The housing is equipped with the vibration drive component and the rotary drive component, and has an internal transmission structure. One end of the rotary shaft is connected to the sample pickup component, and the other end is rotatably connected to the housing. The rotary shaft is connected to the rotary drive component through the transmission structure. The vibration drive component drives the rotary shaft and the sample pickup component to vibrate.

[0009] Furthermore, the vibration drive assembly includes a base and a vibrator, the base and the housing are connected, and the rotating shaft passes through the base; the vibrator is disposed on the base and strikes the rotating shaft.

[0010] Furthermore, a storage basket docking assembly is provided on the rotary shaft.

[0011] Furthermore, the sample pickup assembly includes a rock sampling area, a vibration dust removal area, and a lunar rock and soil retention area connected in sequence.

[0012] Furthermore, the rock sampling area includes several sampling teeth, which are connected to the vibration dust removal area.

[0013] Furthermore, the vibration dust removal zone is provided with several dust removal ports.

[0014] Furthermore, a lunar rock-powder transfer structure is provided on one side of the upper end of the lunar rock and lunar soil retention area, and a lunar rock sample delivery area is provided on the other side.

[0015] Furthermore, the lunar rock-powder transfer structure is an arc-shaped structure.

[0016] Furthermore, the transmission structure includes a bevel gear, which is sleeved on the rotary shaft and connected to the rotary drive assembly.

[0017] Furthermore, the housing is equipped with a robotic arm docking assembly.

[0018] The beneficial effects of the single-motor multi-functional shovel-type picking shovel described in this invention are as follows: (1) The single-motor multi-functional shovel-type picking shovel of the present invention, driven by a robotic arm, penetrates the lunar soil through the set rock sampling area to pick up the target lunar rock. The picked-up lunar rock is in the vibration dust removal area. Under the action of the vibration drive component, the vibration is transmitted to the sample picking component through the rotary shaft, thereby vibrating and removing dust from the lunar rock. The fallen dust is discharged from the dust removal port, thereby increasing the purity of the sample. The processed lunar rock is lifted by the picking shovel and rolled into the lunar rock and lunar soil retention area to wait for transfer. The rotating rotary shaft transfers the lunar rock to other units for further grinding and storage through the lunar rock sample delivery area. The rotating sample picking component allows the lunar rock-powder transfer area to receive the ground lunar rock and its produced lunar rock powder and transfer it to other units for analysis and storage. The present invention, through the rotation of the robotic arm and the structural design of the sample picking component, can smoothly deliver the target sample to other units.

Detailed Implementation

[0021] The technical solutions of the embodiments of the present invention will be clearly and completely described below with reference to the accompanying drawings. It should be noted that, unless otherwise specified, the embodiments and features described in the embodiments of the present invention can be combined with each other. The described embodiments are merely some embodiments of the present invention, not all embodiments. All other embodiments obtained by those skilled in the art based on the embodiments of the present invention without creative effort are within the scope of protection of the present invention.

[0022] Specific implementation method one: See Figures 1-3 This embodiment describes a single-motor, multi-functional shovel-type picking shovel that can pick up lunar rocks with an envelope size of 15mm to 45mm. After picking up the rocks, the shovel can be subjected to preliminary vibration and dust removal, and surface lunar soil samples can be collected. The lunar soil and rock samples can then be transferred to other units via a robotic arm.

[0023] The single-motor multi-functional shovel-type pickup shovel specifically includes a sample pickup component 1, a rotary shaft 2, a storage basket docking component 3, a vibration drive component 4, a housing 5, and a rotary drive component 6. The housing 5 is used to protect the internal components, prevent dust contamination, and provide structural support. The vibration drive component 4 and the rotary drive component 6 are mounted on the housing 5, and a transmission structure is installed inside. One end of the rotary shaft 2 is connected to the sample pickup component 1, and the other end is rotatably connected to the housing 5. The sample pickup component 1 works with the robotic arm to perform operations such as shoveling, vibration, temporary storage, and transfer. The rotary shaft 2 is connected to the rotary drive component 6 through the transmission structure, and the rotary drive component 6 drives the rotary shaft 2 to rotate. The vibration drive component 4 drives the rotary shaft 2 and the sample pickup component 1 to vibrate. By striking the rotary shaft 2, power is transmitted to the sample pickup component for vibration and dust removal.

[0024] The storage basket docking assembly 3 is fixedly mounted on the rotary shaft 2 and positioned between the sample pickup assembly 1 and the vibration drive assembly 4. The storage basket docking assembly 3 can cooperate with the storage basket to drive its transfer. The housing 5 is also equipped with a robotic arm docking assembly 7, which connects to the robotic arm to perform operations such as digging and transferring. The transmission structure includes a bevel gear 8, which is sleeved on the rotary shaft 2 and connected to a bevel gear on the rotary drive assembly 6. This gear transmits torque, changes the direction of rotation, and transfers the kinetic energy of the rotary drive assembly 6 to the rotary shaft 2.

[0025] The vibration drive assembly 4 includes a base and a vibrator. The base and the housing 5 are connected, and the rotating shaft 2 passes through the base. The vibrator is set on the base and strikes the rotating shaft 2.

[0026] The sample pickup assembly 1 includes a rock sampling area 9, a vibration dust removal area 10, a lunar rock-powder transfer structure 11, a lunar rock and lunar soil retention area 12, and a lunar rock sample delivery area 13, which are connected sequentially. The rock sampling area 9 includes several sampling teeth connected to the vibration dust removal area 10, which are used to excavate lunar rock. The sampling teeth are connected by connecting posts to enhance structural strength. The vibration dust removal area 10 has several dust removal ports. The vibration drive assembly 4 transmits power to the sample pickup assembly 1 by striking the rotating shaft 2 to vibrate and remove dust from the lunar rock. Dust falling from the lunar rock is discharged through the dust removal ports. The lunar rock and lunar soil retention area 12 has a lunar rock-powder transfer structure 11 on one side and a lunar rock sample delivery area 13 on the other side; the lunar rock-powder transfer structure 11 is an arc-shaped structure. The rock sampling area 9 is mainly responsible for shoveling the target lunar rocks deep into the lunar soil. The shoveled lunar rocks are placed in the vibration and dust removal area 10 and subjected to vibration and dust removal. The processed lunar rocks are rolled into the lunar rock and lunar soil retention area 12 by lifting the shovel to await transfer. In the lunar rock delivery area 13, the lunar rocks are transferred to other units for further grinding and storage by rotating the rotary shaft 2. Under the rotation of the rotary shaft 2, the ground lunar rocks and their produced lunar rock powder are received in the lunar rock-powder transfer area 11 and transferred to other units for analysis and storage.

[0027] In summary, the single-motor multi-functional shovel-type picking shovel described in this invention, driven by a robotic arm, delves into the lunar soil through the designated rock sampling area 9 to scoop up target lunar rocks. The scooped lunar rocks are placed in the vibration and dust removal area 10. Under the action of the vibration drive component 4, the vibration is transmitted to the sample picking component 1 via the rotary shaft 2, thereby vibrating and removing dust from the lunar rocks. The fallen dust is discharged from the dust removal port, thus increasing the purity of the sample. The processed lunar rocks are lifted by the picking shovel and rolled into the lunar rock and lunar soil retention area 12 to await transfer. The rotating rotary shaft 2 then transfers the lunar rocks to other units via the lunar rock delivery area 13 for further grinding and storage. The rotating sample picking component 1 allows the lunar rock-powder transfer area 11 to receive the ground lunar rocks and their produced lunar rock powder and transfer them to other units for analysis and storage. This invention, through the rotation of the robotic arm and the structural design of the sample picking component, can smoothly deliver the target sample to other units.
