Description

Technical Field

[0001] The present invention belongs to the field of intertidal zone operation machinery, and particularly relates to an intertidal zone sampling assistance tool. Background Art

[0002] In order to monitor the habitat changes of the intertidal zone, it is necessary to reach various pre-set sample plots at low tide to collect various samples such as mud samples, water samples, animals and plants. Since some sampling sites are far from the shore and the intertidal zone silt is relatively deep, scientific and technological personnel need to carry tools and samples with them, which is difficult to walk, and with the change of weather, it is easy to increase fatigue, reduce physical strength, and have low work efficiency. Especially in summer, the exposed intertidal zone surface will also accelerate the decomposition of organic matter, emit some peculiar smells, and at the same time cause a decrease in the oxygen content around. If staying in this environment for a slightly longer time, it is extremely easy to cause sampling personnel to feel uncomfortable, and even suffer from oxygen deficiency and heat stroke. Therefore, how to improve the sampling work efficiency in the intertidal zone environment, reduce the risks of sampling personnel, and develop an auxiliary tool suitable for walking in the intertidal zone area and avoiding sinking during walking is a topic that needs to be explored and innovated.

[0003] After retrieval, the existing publicly disclosed devices for walking on the intertidal zone are as follows:

[0004] 1. Chinese Patent (CN221979876U) discloses an intelligent device for removing Spartina alterniflora on the intertidal zone in its specification, including a vehicle frame, a driving device, a robotic arm assembly, a camera, a processor, a clamping member and a collection box; the driving device is used to drive the vehicle frame to move, the collection box is located at the rear side of the top surface of the vehicle frame, the robotic arm assembly is arranged at the front side of the top of the vehicle frame, the clamping member is arranged at the front side of the robotic arm assembly, the camera is arranged at the top of the front side of the robotic arm assembly, and the shooting direction faces forward, and the processor is electrically connected to the robotic arm assembly, the camera and the clamping member respectively. The driving device mainly drives the driving wheels and tracks through a motor to realize the movement of the device. Among them, using the track structure, the device can also move freely in the intertidal zone area. It can be seen that the track is used as a device for walking on the intertidal zone. However, it is very difficult for the track to move in a relatively muddy area of the intertidal zone.

[0005] 2. Chinese patent application (CN109267563A) discloses a device for laying geotextiles on mudflats, comprising a drive box and a laying frame. A drive motor is fixed to each end of the drive box, a first rotating shaft is fixed to the output end of the drive motor, and a moving wheel is fixed to the end of the first rotating shaft away from the drive motor. A dragging mechanism is fixed between the drive box and the laying frame. A rotating mechanism is fixed to the top of each side of the laying frame, and a rotating shaft is connected between the rotating mechanisms. A geotextile roll is fixed to the rotating shaft. The bottom of the laying frame is an arc-shaped structure, and a first slot is formed at the end of the bottom of the laying frame away from the drive box. A fixing mechanism is clamped inside the first slot. Anti-sinking blocks are evenly inserted into the moving wheel along the circumference. It can be seen that the anti-sinking blocks are installed radially along the circumference of the moving wheel and are flat-plate structures. When the anti-sinking blocks are inserted into the mudflat and swung out, the amount of mudflat pushed by the anti-sinking blocks is large, and the resistance they encounter is extremely large, which increases the load on the drive motor and makes it easy to damage.

[0006] As can be seen from the above, the existing mudflat walking device still has defects. Therefore, in view of the defects of the above-mentioned prior art, a mudflat sampling assisting tool that can carry people, transport tools and samples has been developed. Summary of the Invention

[0012] Furthermore, the steering mechanism includes a support frame, which is mounted on the top of the guide body; a support tube, which is connected to the frame through a support rod; and a vertical rod, one end of which passes through the support tube and is connected to the drive seat, and the other end is connected to the steering rod; the drive seat is connected to the support frame.

[0013] Furthermore, the mudflat sampling assist tool of the present invention also includes a support rod, a nut and a limit block. One end of the support rod is connected to the guide body, and the other end is passed through a support frame and threadedly connected to the nut. The limit block is installed on the support rod and is located between the guide body and the support frame.

[0014] Furthermore, the mudflat sampling assisting tool of the present invention also includes a limiting ring, which is installed on the vertical rod and fits the top of the supporting tube.

[0015] Furthermore, the mudflat sampling assisting tool of the present invention also includes a cover body, the guide body is provided with an accommodating space, the top of the accommodating space is provided with a box opening, and the cover body is movably buckled on the box opening.

[0016] Furthermore, the driving mechanism includes a driving motor, the driving motor is provided with an output shaft, the output shaft is mounted on the driving wheel; a driving shaft, the driving shaft is mounted on the driven wheel, and both ends are respectively connected to an anti-sinking wheel for transmission, and the driven wheel is connected to the driving wheel for transmission; a battery; a controller, the controller is provided with a power switch; and a speed control handle, the speed control handle is installed on the direction adjustment mechanism; wherein, the controller is electrically connected to the battery, the speed control handle, and the driving motor.

[0018] Another technical solution based on the same inventive concept: A method for using a beach sampling assistance tool, the method comprising the following steps:

[0019] (1) Place the beach sampling assistance tool on the beach, and the guiding body and the hollow box body support the beach sampling assistance tool to float on the beach;

[0020] (2) Then place the beach sampling tool on the top of the vehicle frame;

[0021] (3) The beach sampling staff sits in the sample box and starts the driving mechanism. The driving mechanism drives the anti-sinking wheels on both sides of the vehicle frame to rotate, and multiple arc-shaped mud plates on the anti-sinking wheels rotate. When the arc-shaped mud plates rotate and insert into the beach, the whole beach sampling assistance tool is pushed forward. The beach sampling staff holds the steering mechanism and controls the rotation of the guiding body through the steering mechanism to adjust the forward direction.

[0022] Advantages of the present invention over the prior art:

[0023] 1. The present invention can walk on the beach, can carry people, can transport the tools required for beach sampling and the samples obtained from sampling, and overcomes the problem that sampling personnel have difficulty walking on the beach during existing beach sampling. The hollow box body can prevent the vehicle frame from sinking into the beach. The guiding body with a hull structure floats on the beach. The driving mechanism drives the anti-sinking wheels on both sides of the vehicle frame, and the two anti-sinking wheels push the beach sampling assistance tool of the present invention forward. The sampling personnel can sit in the sample box on the vehicle frame, and the tools required for beach sampling can be placed on the vehicle frame, avoiding the sampling personnel from carrying sampling tools and walking on the beach, and reducing the difficulty of beach sampling work for the sampling personnel. The beach sampling assistance tool of the present invention can move towards the beach sampling point under the control of the sampling personnel. The samples obtained from sampling are placed in the sample box, and then the beach sampling assistance tool can be controlled to return.

[0024] 2. The mud guard of the present invention can block the beach mud and sewage thrown out by the rotation of the anti-sinking wheels, can keep the top of the vehicle frame dry and hygienic, and effectively prevent the beach mud and sewage from polluting the top of the vehicle frame. The mud guard is divided into a first arc section and a second arc section, which is beneficial to increasing the interval between the first arc section and the anti-sinking wheel, avoiding that the interval is too small and is easily filled with beach mud, thus affecting the work of the anti-sinking wheel; while the first arc section extends outward and bends upward from the vehicle frame, so that the beach mud centrifugally thrown out by the anti-sinking wheel hits the convex surface. The contact surface between the beach mud and the first arc section is not a plane, and the beach mud can quickly fall downward under the action of its own gravity, effectively preventing the beach mud from accumulating on the first arc section.

[0025] 3. In the anti-sinking wheel of the present invention, a plurality of arc-shaped mud plates are circumferentially spaced and connected between two parallel and spaced support rings. The periphery of the arc-shaped mud plate is not a closed structure. During the rotation of the arc-shaped mud plate inserted into the beach mud, the pushed beach mud can move into the space between the two support rings, which can reduce the resistance of the beach mud to the arc-shaped mud plate and reduce the load on the driving motor.

DETAILED DESCRIPTION

[0035] In order to enable people skilled in the art to better understand the technical solutions in this application, the technical solutions of the present invention will be clearly and completely described below with reference to the accompanying drawings and embodiments. Obviously, the described embodiments are only part of the embodiments of this application. Based on the embodiments in this application, all other embodiments obtained by ordinary technicians in this field without making creative work should fall within the scope of protection of this application.

[0036] Example 1:

[0037] like Figures 1 to 6 As shown, this embodiment of a mudflat sampling assist tool includes a guide body 1, a frame 22, a hollow box 28, anti-sinking wheels 25, and a steering mechanism. The guide body 1 has a hull structure, and the side panels on both sides along the length direction protrude from the bottom surface; the sample box 17 and the drive mechanism are mounted on the frame 22; the hollow box 28 is mounted on the bottom of the frame 22; the anti-sinking wheels 25 are mounted on both sides of the frame 22, and the anti-sinking wheels 25 are connected to the drive mechanism. The anti-sinking wheels 25 include multiple curved mud plates 251, which are spaced apart around the circumference, with a central angle of 90° to 180° and a length of 30cm to 100cm. The steering mechanism is mounted on one end of the frame 22 and connected to the guide body 1. The steering mechanism is driven to drive the guide body 1 to rotate.

[0038] like Figures 1 - 3As shown in Fig. 6, the two side surfaces of the guiding body 1 protrude from the bottom surface 103. The parts of the side surfaces protruding from the bottom surface form the resistance ends. The distance that the resistance ends protrude from the bottom surface can be 2 - 5 cm. During use, the protruding distance of the resistance ends can be 2 cm, 3 cm, 4 cm or 5 cm, etc. When the resistance ends protrude from the bottom surface, they can be inserted into the mud of the tidal flat relative to the bottom surface. When the resistance ends are parallel to the moving direction of the tidal flat sampling assisting tool of the present invention, at this time, the resistance generated by the resistance ends is the smallest. When the resistance ends form an intersection with the moving direction of the tidal flat sampling assisting tool of the present invention, it will block the advancing direction, enabling the guiding member to change the moving direction.

[0039] It can be understood that during the process of the angle between the resistance end and the moving direction changing from 0 to 90°, the resistance received by the resistance end gradually increases. When the angle between the resistance end and the moving direction is 0°, that is, the resistance end and the moving direction are parallel, at this time, the resistance received by the resistance end is the smallest; when the angle between the resistance end and the moving direction is 90°, at this time, the resistance received by the resistance end is the largest.

[0040] When the adjusting mechanism drives the guiding member 1 to rotate, the resistance end 103 on the guiding member 1 rotates accordingly. The resistance end provides resistance, causing the guiding member to stop moving in the original moving direction. And under the action of the thrust force, the guiding member is pushed to move in the direction where the resistance end is inclined, enabling the guiding member to change the moving direction.

[0041] To facilitate the user to place the feet, a connecting rod 32 and a footrest rod 31 are additionally installed. One end of the connecting rod 32 is connected to the vehicle frame 22, and the other end is connected to the footrest rod 31. The footrest rod 31 is used for the feet to rest on.

[0042] The connecting rod 32 can extend outward and downward relative to the vehicle frame 22, enabling the connecting rod to be installed in a crossed manner with the vehicle frame. Furthermore, it can facilitate the footrest rod to deviate from the vehicle frame, which is beneficial for the user to comfortably rest the feet.

[0043] As Figures 1 to 3 shown, the guiding body is in the structure of a hull. That is, one end of the guiding body is provided with an inclined surface that slopes downward, and the inclined surface is arc-transitionally connected to the bottom surface of the guiding body, which is beneficial for the guiding body to break through the mud on the tidal flat when moving forward and can reduce the resistance exerted by the tidal flat on the guiding body.

[0044] As Figures 1 to 3 shown, for a structure of the guiding body, a cover body 5 is additionally installed. The guiding body 1 is provided with a receiving space 101, and the top of the receiving space 101 is provided with a box opening 102. The cover body 5 is movably buckled on the box opening 102. The cover body can prevent sundries from falling into the receiving space.

[0045] As Figure 1 、 2As shown, a structure of the hollow box body 28: The hollow box body 28 is provided with a groove 281 with an open top. This can not only reduce the weight of the hollow box body but also facilitate the floating of the hollow box body on the beach. It can be understood that the hollow box body 28 can support the vehicle frame 22 advantageously and effectively prevent the vehicle frame from sinking into the beach.

[0046] As Figure 1 , 2 , 4, 5 show that a plurality of arc-shaped mud plates 251 are installed at circumferential intervals on the anti-sinking wheel 25, and the plurality of arc-shaped mud plates 251 are installed longitudinally, that is, the arc-shaped mud plates extend along the axial direction of the anti-sinking wheel. When the anti-sinking wheel is placed on the beach, the arc-shaped mud plates located at the bottom of the anti-sinking wheel squeeze the beach mud, and the beach mud supports the arc-shaped mud plates in the opposite direction, so that the arc-shaped mud plates can support the anti-sinking wheel to float on the beach.

[0047] As Figure 1 , 2 , 4, 5 show that one end of the arc-shaped mud plate 251 is fixed and the other end extends outward in an arc. When the anti-sinking wheel rotates counterclockwise, the plurality of arc-shaped mud plates on the anti-sinking wheel are cyclically inserted into the beach mud, so as to reversely push the anti-sinking wheel forward, and the anti-sinking wheel then pushes the overall beach sampling assistance tool forward.

[0048] The first specification of the arc-shaped mud plate 251 can be a central angle of 90° and a length of 30 cm.

[0049] The second specification of the arc-shaped mud plate 251 can be a central angle of 135° and a length of 65 cm.

[0050] The third specification of the arc-shaped mud plate 251 can be a central angle of 180° and a length of 100 cm.

[0051] It can be understood that the arc-shaped mud plates are not limited to the above three specifications. During use, they can be adjusted according to work needs to select a suitable arc-shaped mud plate specification. It should be noted that the length of the above-mentioned arc-shaped mud plates is not the arc length but the length extending along the axial direction of the arc-shaped mud plates.

[0052] It should also be noted that when the length of the arc-shaped mud plate is 30 cm to 100 cm, it can make the contact area between the arc-shaped mud plate and the beach mud large enough, which is conducive to the beach mud squeezing and pushing the arc-shaped mud plate upward, so as to prevent the anti-sinking wheel from sinking deeply into the beach mud.

[0053] A drive mechanism structure. The drive mechanism includes a drive motor 19, a drive shaft 26, a battery 16, a controller 29, and a speed control handle 14. The drive motor 19 has an output shaft 20, which is mounted on a drive wheel 21. The drive shaft 26 is mounted on a driven wheel 27, with both ends drivingly connected to an anti-sinking wheel 25. The driven wheel 27 is in a driving connection with the drive wheel 21. The controller 29 has a power switch 30. The speed control handle 14 is mounted on the steering mechanism. The controller 29 is electrically connected to the battery 16, the speed control handle 14, and the drive motor 19.

[0054] One installation method of the drive shaft 26 and the frame 22: the drive shaft 26 is horizontally mounted on the frame 22. The drive shaft 26 and the frame 22 are connected by a bearing seat 34. The drive shaft 26 can rotate relative to the bearing seat 34.

[0055] A transmission connection structure between the driving wheel 21 and the driven wheel 27: The driving wheel 21 and the driven wheel 27 are connected to each other through the transmission member 23. When the transmission member 23 is a transmission chain, the driving wheel 21 and the driven wheel 27 are both sprockets. When the transmission member 23 is a transmission belt, the driving wheel 21 and the driven wheel 27 are both pulleys.

[0056] It is understandable that if Figure 1 、 2 As shown in , 4, one matching of the driving wheel and the driven wheel can be: the driving wheel adopts a small wheel, and the driven wheel adopts a large wheel.

[0057] A transmission connection structure between the output shaft 20 and the driving wheel 21: the output shaft 20 and the driving wheel 21 are connected by a key. The output shaft drives the driving wheel to rotate through the key.

[0058] A transmission connection structure between the driving shaft 26 and the driven wheel 27: the driving shaft 26 and the driven wheel 27 are connected by a key.

[0059] It is understandable that the battery serves as the power supply.

[0060] One structure of the battery may be an aluminum battery, and the specifications of the aluminum battery may be 60V and 32A.

[0061] The speed regulating handle 14 is electrically connected to the controller 29 and is used to regulate the speed of the driving motor 19 .

[0062] A control method of the speed control handle 14:

[0063] Turn the speed control handle 14 clockwise, and the controller 29 controls the driving motor to increase the speed, so as to realize the accelerated movement of the beach sampling assistance tool of the present invention. When the speed control handle 14 is fixed at a certain position, the driving motor maintains a constant speed at this position, so as to realize the uniform movement of the beach sampling assistance tool of the present invention. Turn the speed control handle 14 counterclockwise, and the controller 29 controls the driving motor to decelerate, so as to realize the decelerated movement of the beach sampling assistance tool of the present invention.

[0064] As Figures 1 to 3 shown, the side and bottom of one end of the hollow box body 28 close to the guide body 1 are connected by an arc transition. This can help reduce the moving resistance of the hollow box body.

[0065] The working mode of the driving mechanism:

[0066] Turn on the power switch 30 on the controller 29, and the driving motor 19 is in a charged state.

[0067] Turn the speed control handle 14, the controller 29 controls the driving motor 19 to start, the driving motor 19 drives the output shaft 20 to rotate, the output shaft 20 drives the driving wheel 21 to rotate, the driving wheel 21 drives the driven wheel 27 to rotate through the transmission member 24, the driven wheel 27 drives the driving shaft 26 to rotate, and the driving shaft 26 drives the anti-sinking wheels 25 at both ends to rotate. Under the push of the two anti-sinking wheels 25, the beach sampling assistance tool of the present invention moves forward.

[0068] During the movement, the guide body 1 is rotated through the steering mechanism to realize steering. For example, when the steering mechanism fixes the guide body, the beach sampling assistance tool of the present invention moves along the direction pointed by the guide body. Of course, according to needs, the guide body 1 can be rotated through the steering mechanism so that the beach sampling assistance tool of the present invention moves towards the destination.

[0069] The guide member 1 and the bottom surface of the hollow box body 28 are flat, which is beneficial to increasing the contact area with the beach surface. The guide member has a hollow hull structure, and the hollow box body is a hollow structure. The guide member and the hollow box body can help increase the volume of the displaced beach medium. The guide member and the hollow box body float on the beach, so that the overall structure can float on the beach. When the driving mechanism drives the anti-sinking wheels to rotate, the anti-sinking wheels push the beach sampling assistance tool of the present invention forward. During the movement, the steering mechanism controls the guide member, and the guide member plays a guiding role.

[0070] In some alternative embodiments, in order to block the beach mud thrown out when the anti-sinking wheels rotate, a mud guard 18 is additionally installed. As Figure 1 、 2As shown, a fender 18 is suspended above the anti-sinking wheel 25; the fender 18 includes a first arc segment 181 and a second arc segment 182. The first arc segment 181 is placed above the anti-sinking wheel 25, extends to both sides and bends downward. One end of the second arc segment 182 is tangentially connected to the first arc segment 181, and the other end extends outside the frame 22 and bends upward.

[0071] The fender 18 can block the beach mud thrown outwards when the anti-sinking wheel rotates.

[0072] The first arc segment 181 extends outside the frame 22 and bends upward, which can block the beach mud and sewage centrifugally thrown out when the anti-sinking wheel rotates, and can effectively prevent the beach mud and sewage from polluting the top of the frame. The interval between the first arc segment and the anti-sinking wheel increases. When the beach mud thrown out by the anti-sinking wheel adheres to the first arc segment, it does not affect the rotation of the anti-sinking wheel. The first arc segment is an arc structure. For the beach mud hitting the first arc segment, the contact surface between the beach mud and the first arc segment is not a plane and there is a height difference. Therefore, the beach mud adhering to the first arc segment can quickly fall off by its own gravity, avoiding increasing the load. It solves the problem that the close interval between the existing fender and the wheel is likely to cause the interval to be filled with mud and affect the rotation of the wheel.

[0073] The second arc segment 182 can further block the sewage carried by the anti-sinking wheel during rotation from being thrown to the top of the frame, effectively preventing the sewage from polluting the top of the frame and facilitating keeping the top of the frame dry. The second arc segment bends downward, which is conducive to the quick detachment of the sewage from the second arc segment.

[0074] As Figure 1 、 2 shown, the first arc segment and the second arc segment are connected in an externally tangent manner, which is conducive to the flatness of the connection part, and thus conducive to the falling of the adhering beach mud.

[0075] As Figure 1 、 2 shown, the first arc segment 181 is installed on the frame 22 through a suspension rod 24. The second arc segment 182 is installed on the frame 22 through another suspension rod 24. The first arc segment 181 and the second arc segment 182 are suspended on the frame 22 through the suspension rod 24 and are placed above the anti-sinking wheel 25.

[0076] In some alternative embodiments, a structure of the anti-sinking wheel is given. The anti-sinking wheel 25 further includes an annular support frame and a drive sleeve 255. Annular support frames are installed at both ends of the drive sleeve 255, and multiple arc-shaped mud plates 251 are installed at circumferential intervals between the two annular support frames; the annular support frame includes a support ring 252, a reinforcing rod 253 and a support disc 254. The support disc 254 is placed inside the support ring 252 and is connected by multiple reinforcing rods 253. Among them, the center of the support disc 254 coincides with the center of the support ring 252.

[0077] A plurality of reinforcing rods 253 are used to connect the support ring 252 and the support disc 254. A through-hole is formed between adjacent reinforcing rods. When the anti-sinking wheel travels on the tidal flat, the tidal flat mud can be discharged outward through the through-hole.

[0078] One structure of the drive sleeve 255 can be a cylinder. One transmission connection structure between the drive sleeve 255 and the drive shaft 26 is that the drive sleeve 255 and the drive shaft 26 are connected by a key. The drive shaft 26 can drive the drive sleeve 255 to rotate through the key.

[0079] The number of the installed reinforcing rods 253 can be 3, 4, 5, 6, 7, 8 or the like.

[0080] The support rings 252 at both ends of the drive sleeve are arranged in parallel at intervals. The two support rings 252 are used to support and install the arc-shaped mud board 251. It can be understood that the connection method between the support ring and the arc-shaped mud board can be welding connection.

[0081] It should be noted that a through-hole is formed at the central position of the support disc 254, and the support disc is sleeved on the drive sleeve 255 through the through-hole. One connection method between the support disc and the drive sleeve is that the support disc and the drive sleeve can be fixedly connected by welding.

[0082] The arc-shaped mud board 251 is installed on two support rings 252 arranged in parallel at intervals. The periphery of the arc-shaped mud board is not closed. During the process of the arc-shaped mud board being inserted into and rotated out of the tidal flat mud, the tidal flat mud can move into the interval between the two support rings, reducing the resistance to the arc-shaped mud board, reducing the load of the drive motor, and achieving the protection of the drive motor.

[0083] In some alternative embodiments, a structure of the steering mechanism is given. The steering mechanism includes a support frame, a support cylinder 10 and a vertical rod 12. The support frame is erected on the top of the guide body 1; the support cylinder 10 is connected to the vehicle frame 22 through a support rod 33; one end of the vertical rod 12 passes through the support cylinder 10 and is connected to the drive seat 9, and the other end is connected to the steering rod 13; the drive seat 9 is connected to the support frame.

[0084] As Figures 1 to 3 shown, the speed control handle 14 is installed at one end of the steering rod 13, and the other end of the steering rod 13 is installed with a handle 13.

[0085] As Figures 1 to 3 shown, the support frame includes a support rod 6 and a cross bar 8, and the support rod 6 is installed at both ends of the cross bar 8. When the support frame is erected on the guide body, each side of the guide body is connected to a support rod 6.

[0086] Furthermore, a connection structure between the guide body 1 and the support rod 6 is additionally provided with a support rod 2, a nut 3, and a stopper 4. One end of the support rod 2 is connected to the guide body 1, and the other end passes through the support rod 6 and is threadedly connected to the nut 3. The stopper 4 is installed on the support rod 2 and is located between the guide body 1 and the support frame.

[0087] The limiting block 4 and the nut 3 on the support rod 2 can clamp and fix the support rod 6.

[0088] like Figures 1 to 3 As shown, two drive rods 91 extend outward from the drive base 9, intersecting each other. Both drive rods 91 are connected to the crossbar 8 via struts 7. The two drive rods 91 and the crossbar 8 form a triangular structure. It is understood that when the vertical rod 12 is rotated under force, it drives the drive base 9, and the two drive rods 91 on the drive base rotate accordingly. The two drive rods 91 simultaneously drive the crossbar 8 in the same direction, which in turn drives the support rods 8. The two support rods 6 then drive the guide body 1, which in turn rotates to achieve the desired direction.

[0089] The support tube 10 and the frame 28 can be connected by at least one support rod 33. The number of support rods 33 installed can be 1, 2 or 3. Figures 1 to 3 As shown, the support tube 10 and the frame 28 are connected by two support rods 33. One end of the two support rods is closely connected on the support tube, and the other end is spaced apart on the frame. The two support rods and the frame form a triangular structure, which can help the two support rods to stably support the support tube.

[0090] like Figures 1 to 3 As shown, to prevent the end of the guide body closest to the frame from tilting upward, a pressure rod 35 and a diagonal brace 36 are additionally installed. The diagonal brace 36 is installed at both ends of the crossbar 8. The two diagonal braces 36 are connected by a pressure rod 35, and the pressure rod 35 is attached to the top surface of the guide body 1. The interaction between the diagonal brace 36 and the pressure rod 35 can prevent the end of the guide body closest to the frame from tilting upward, which can further facilitate the stable movement of the guide body.

[0091] In some optional embodiments, in order to prevent the vertical rod from detaching from the support tube, a limit ring 11 is additionally installed. The limit ring 11 is installed on the vertical rod 12 and fits against the top of the support tube 10. The limit ring 11 can limit the vertical rod 12 from moving downward along the support tube 10.

[0092] In some optional embodiments, such as Figure 6 As shown, a motor protection cover 37 and a storage basket 38 are additionally installed. The motor protection cover 37 covers the motor 19 and is provided with a through slot for the transmission member to pass through. The through slot allows the transmission member 23 to pass through, thereby enabling the driving wheel 21 and the driven wheel 27 to be smoothly connected through the transmission member 23.

[0093] The motor protection cover 37 can protect the drive motor 19.

[0094] The storage basket 38 is installed at the rear end of the vehicle frame 22 and can be used to store items, sampling samples, etc.

[0095] Based on the same inventive concept, another technical solution of the present invention: a method for using a beach sampling assistance tool, the method for using includes the following steps:

[0096] (1) Place the beach sampling assistance tool on the beach, and the guiding body 1 and the hollow box body 28 support the beach sampling assistance tool to float on the beach;

[0097] (2) Then place the beach sampling tool on the top of the vehicle frame 22;

[0098] (3) The beach sampling staff sits in the sample box 17, starts the driving mechanism, the driving mechanism drives the anti-sinking wheels 25 on both sides of the vehicle frame 22 to rotate, and the multiple arc-shaped mud plates 251 on the anti-sinking wheels 25 rotate. When the arc-shaped mud plates rotate and insert into the beach, the whole beach sampling assistance tool is pushed forward. The beach sampling staff holds the steering mechanism and controls the rotation of the guiding body 1 through the steering mechanism. The side surface of the guiding body 1 protrudes from the bottom surface to form a resistance end. When turning, the resistance end pushes the beach soil to receive resistance, blocking the guiding body from continuing to move in the original moving direction, so that the guiding body moves in the direction it deflects, and the advancing direction can be adjusted.

[0099] Obviously, the above embodiments are only examples clearly described and not limitations on the implementation manners. For those of ordinary skill in the art, other different forms of changes or variations can be made based on the above description. It is not necessary and impossible to list all the implementation manners here. And the obvious changes or variations derived therefrom are still within the protection scope of the present invention.
