Description

Technical Field

[0001] This utility model relates to the field of environmental protection construction machinery technology, specifically to a pull-out Spartina alterniflora removal device. Background Technology

[0002] Spartina alterniflora, belonging to the Poaceae family and the Spartina alterniflora genus, is a perennial herbaceous plant that grows in the intertidal zone of salt marshes. After years of artificial cultivation and natural dispersal, Spartina alterniflora has spread rapidly throughout coastal mudflats. It exhibits broad adaptability from freshwater to seawater, is tolerant of flooding and salinity, and can still grow normally even under conditions where each tide submerges for up to 6 hours. It can reproduce both sexually and asexually, has a well-developed underground root system that can reach depths of 50-100 cm in the soil, and easily undergoes secondary regrowth, making it a typical halophyte. Furthermore, the above-ground parts of Spartina alterniflora are tall and robust, with upright stems reaching up to 2 meters in height, and are capable of sexual reproduction, bringing a series of negative impacts to the local natural ecosystem, biodiversity, environmental resources, and ecological security.

[0003] To eradicate Spartina alterniflora, both the surface and underground parts must be removed simultaneously. If any part is not treated properly or the root system is not thoroughly removed, Spartina alterniflora is very likely to recur.

[0004] Existing Spartina alterniflora control methods generally employ mowing and tilling to physically remove the root system and surface parts. However, the tilling depth is limited to no more than 0.5 meters, and the root system can only be partially or completely removed during tilling, leading to easy recurrence of Spartina alterniflora and a low eradication rate. Furthermore, current tilling methods involve rotary tilling the entire tidal flat area, causing significant soil damage and impacting the habitat of existing benthic organisms.

[0005] As can be seen from the above, the existing technology has the problem of low control rate of Spartina alterniflora. Utility Model Content

[0006] The main purpose of this invention is to provide a pull-out Spartina alterniflora removal device to solve the problem of low Spartina alterniflora removal rate in the prior art.

[0011] Furthermore, there are multiple first and second removal tentacles, and the multiple first removal tentacles and multiple second removal tentacles are arranged at intervals along the annular direction of the transmission chain and correspond one to one.

[0012] Furthermore, the first and second removal tentacles have the same structure, including a clamping part, a guide rod, and a connecting part. The connecting part is connected to the transmission mechanism, one end of the guide rod is connected to the connecting part, and the clamping part is adjustablely connected to the guide rod.

[0013] Furthermore, the clamping part is a cone shape with a diameter that gradually decreases in the direction away from the connecting part.

[0014] Furthermore, the axial projection of the end of the clamping portion of one of the first and second removal tentacles away from the connecting portion is located within the connecting portion of the other, so that the connecting portion limits and stops the clamping portion.

[0015] Furthermore, the clamping part has a central hole for fitting onto the guide rod, and the clamping part is slidably connected to the guide rod; or the guide rod is a telescopic rod structure.

[0016] Furthermore, the removal mechanism has a first position, a second position, and a third position located at the front end, the middle, and the rear end, respectively. The distance between the first removal tentacle and the second removal tentacle located at the second position is smaller than the distance between the first removal tentacle and the second removal tentacle located at the first position, and the distance between the first removal tentacle and the second removal tentacle located at the second position is smaller than the distance between the first removal tentacle and the second removal tentacle located at the third position.

[0017] Furthermore, the removal assembly also includes two second rotating arms, which are rotatably disposed on both sides of the retractor and rotatably connected to the first removal component and the second removal component, respectively.

In this way, the pulling component cleans up the area where Spartina alterniflora has been pulled out, thereby replacing the existing method of mowing and tilling.

[0035] It should be noted that, unless otherwise specified, the embodiments and features described in this application can be combined with each other. The present invention will now be described in detail with reference to the accompanying drawings and embodiments.

[0036] It should be noted that, unless otherwise specified, all technical and scientific terms used in this application have the same meaning as commonly understood by one of ordinary skill in the art to which this application pertains.

[0037] In this utility model, unless otherwise stated, directional terms such as "upper," "lower," "top," and "bottom" are generally used in relation to the direction shown in the accompanying drawings, or in relation to the vertical, perpendicular, or gravitational direction of the component itself; similarly, for ease of understanding and description, "inner" and "outer" refer to the inner and outer contours of each component itself, but the above directional terms are not used to limit this utility model.

[0038] Obviously, the embodiments described above are only some embodiments of this utility model, and not all embodiments. Based on the embodiments of this utility model, all other embodiments obtained by those skilled in the art without creative effort should fall within the protection scope of this utility model.

[0039] To address the problem of low control rates of Spartina alterniflora in existing technologies, this invention provides a pull-out Spartina alterniflora removal device.

[0040] like Figures 1 to 2 As shown, this application provides a pull-out type Spartina alterniflora removal device, including a frame 10, a traveling component 20, a pulling component 30, and a collecting component 40. The traveling component 20 is disposed at the lower part of the frame 10 and is used to drive the frame 10 to move. The pulling component 30 is disposed at the front end of the frame 10 and is used to pull out Spartina alterniflora. The collecting component 40 is disposed on the frame 10 and is used to collect the Spartina alterniflora pulled out by the pulling component 30.

[0041] The technical solution of this application cleans the area where Spartina alterniflora is removed by removing components, thereby replacing the existing method of mowing and tilling. This ensures that the damage to the original soil is minimized and that all roots of Spartina alterniflora are removed as much as possible, avoiding secondary recurrence caused by root residues, and greatly improving the control rate of Spartina alterniflora.

[0042] It should be noted that in this embodiment, the front end is based on the direction of travel of the pull-out Spartina alterniflora removal device. The end facing the direction of travel of the removal device is the front end, and the end facing the opposite direction of travel of the removal device is the rear end.

[0043] In this embodiment, the frame 10 may be equipped with a driver's cab, thereby enabling manual driving and operation. Furthermore, the pull-out Spartina alterniflora removal device in this embodiment can also be operated autonomously, with remote control enabling operations such as movement, height adjustment, and high / low position removal of the removal device.

[0044] In this embodiment, the collection component 40 can collect and pack the uprooted Spartina alterniflora plants. After packing, they can be transferred to a waiting vessel for centralized transportation, thereby avoiding the secondary pollution caused by the accumulation of harvested Spartina alterniflora on the mudflats and the recurrence of Spartina alterniflora due to the spillage of grass seeds during the treatment process.

[0045] like Figures 3 to 6 As shown, the removal assembly 30 includes a removal mechanism 31, a transmission mechanism 32, and a retractor 33. The removal mechanism 31 includes a first removal member 311 and a second removal member 312, which are spaced apart and arranged opposite to each other. The first removal member 311 includes a first removal tentacle 3111, and the second removal member 312 includes a second removal tentacle 3121. The first and second removal tentacles 3111 and 3121 extend towards each other and are staggered, for clamping Spartina alterniflora. It can be understood that the area between the first and second removal tentacles 3111 and 3121 is the clamping area for Spartina alterniflora. Transmission mechanisms 32 are respectively disposed on the first removal member 311 and the second removal member 312. The ends of the first removal tentacle 3111 and the second removal tentacle 3121 are respectively connected to the transmission mechanisms 32. The transmission mechanisms 32 drive the first removal tentacle 3111 and the second removal tentacle 3121 to move toward the collecting assembly 40 to perform the first removal operation. The collector 33 is horizontally rotatable and is positionally adjustable to the removal mechanism 31, used to transport Spartina alterniflora to the removal mechanism 31.

[0046] Furthermore, such as Figures 3 to 6As shown, the first removal component 311 also includes a first transmission housing 3112, and the second removal component 312 also includes a second transmission housing 3122. The first transmission housing 3112 and the second transmission housing 3122 are centrally symmetrical irregular structures, and the transmission mechanism 32 is located in the first transmission housing 3112 and the second transmission housing 3122 respectively.

[0047] Specifically, in this embodiment, the first transmission housing 3112 and the second transmission housing 3122 are upright, tilted downwards, and have a Z-shaped structure. It can be understood that the area between the first transmission housing 3112 and the second transmission housing 3122 is the removal area of ​​the removal assembly 30. The first removal tentacle 3111 and the second removal tentacle 3121 are horizontally positioned in the removal area and move with the transmission mechanism 32.

[0048] like Figures 3 to 6 As shown, in this embodiment, the transmission mechanism 32 includes a transmission chain 321 and a sprocket 322. The sprocket 322 is connected and fixed to the first transmission housing 3112 and the second transmission housing 3122. The transmission chain 321 is annular and is adapted to the shapes of the first transmission housing 3112 and the second transmission housing 3122, respectively. The first removal tentacle 3111 and the second removal tentacle 3121 are respectively connected to the transmission chain 321 on both sides. Specifically, the transmission chain 321 is a Z-shaped annular chain.

[0049] Furthermore, the pull-out Spartina alterniflora removal device also includes a drive mechanism. The first drive mechanism is driven and connected to the transmission mechanism 32, specifically to the sprocket 322, thereby driving the transmission chain 321 to move along a Z-shaped circular trajectory.

[0050] In this embodiment, there are multiple first removal tentacles 3111 and multiple second removal tentacles 3121. These multiple first removal tentacles 3111 and multiple second removal tentacles 3121 are spaced apart and correspond one-to-one along the annular direction of the transmission chain 321. It can be understood that one first removal tentacle 3111 and one second removal tentacle 3121 form a clamping structure, thereby clamping and fixing the Spartina alterniflora plant, which then moves backward under the drive of the transmission mechanism 32, thus removing the Spartina alterniflora.

[0051] In this embodiment, the transmission mechanisms 32 on both sides of the removal assembly 30 drive the first removal tentacle 3111 and the second removal tentacle 3121 to move at the same speed.

[0052] Understandably, the end of the removal component 30 closest to the rack 10 is the rear end, which is also the top end; the retractor 33 of the removal component 30 is located at its front end, which is also the bottom end.

[0053] like Figures 1 to 2 , Figure 7 and Figure 7 As shown, in this embodiment, the collection component 40 includes a collection plate 41 and a receiving chamber 42. The receiving chamber 42 is disposed on the frame 10, and the collection plate 41 is disposed at the front end of the frame 10. The collection plate 41 includes a first plate body 411 and a second plate body 412 connected in sequence. The first plate body 411 is horizontally disposed, and the second plate body 412 is inclinedly disposed. Conveyor belts 43 are respectively disposed on the first plate body 411 and the second plate body 412 for conveying the Spartina alterniflora removed by the removal component 30 to the receiving chamber 42. That is, the conveyor belt 43 on the first plate body 411 is a horizontal conveyor belt, and the conveyor belt 43 on the second plate body 412 is an upwardly inclined conveyor belt. Specifically, the frame 10 has a hollow channel extending from front to back. The collection plate 41 overlaps with the hollow channel. The hollow channel is also equipped with a conveyor belt 43. The storage bin 42 is located at the rear end of the frame 10. The collection plate 41 is located below the removal component 30. The Spartina alterniflora plants that fall on the collection plate 41 are transported to the storage bin 42 in sequence through each conveyor belt 43.

[0054] Furthermore, such as Figure 7 As shown, the first plate 411 has inclined surfaces 4111 on both sides, sloping inward from the outside. In this embodiment, the conveyor belts 43 are located at the middle position of the first plate 411 and the second plate 412. By setting the inclined surfaces 4111, the Spartina alterniflora plants falling on the first plate 411 can be guided onto the conveyor belts 43, ensuring conveying efficiency. Furthermore, a vertical baffle is also provided around the periphery of the connection between the first plate 411 and the second plate 412. The baffle is connected to the inclined surfaces 4111, thereby guiding the Spartina alterniflora plants onto the conveyor belts 43 of the second plate 412 and preventing the Spartina alterniflora plants from falling from the collecting plate 41 to other positions.

[0055] In this embodiment, the removal mechanism 31 has a first position, a second position, and a third position located at the front end, middle, and rear end, respectively. The distance between the first removal tentacle 3111 and the second removal tentacle 3121 located at the second position is smaller than the distance between the first removal tentacle 3111 and the second removal tentacle 3121 located at the first position. The distance between the first removal tentacle 3111 and the second removal tentacle 3121 located at the second position is smaller than the distance between the first removal tentacle 3111 and the second removal tentacle 3121 located at the third position. Specifically, this embodiment achieves different distances between the first removal tentacle 3111 and the second removal tentacle 3121 at the three positions through a centrally symmetrical first transmission housing 3112 and second transmission housing 3122.

[0056] In this embodiment, the transmission chain 321 moves from the rear end to the front end on the upper surface and from the front end to the rear end on the lower surface. That is, since the collecting plate 41 is located below the removal assembly 30, the Spartina alterniflora held by the removal mechanism 31 needs to move from the bottom to the rear end so that it can fall onto the collecting plate 41. Of the three positions mentioned above, the first position is the entry position of Spartina alterniflora, that is, entering the removal mechanism 31. Therefore, a relatively large distance is needed between the first removal tentacle 3111 and the second removal tentacle 3121. The second position is the removal position of Spartina alterniflora. At this time, the first removal tentacle 3111 and the second removal tentacle 3121 clamp the Spartina alterniflora and continue to move towards the rear end to remove the Spartina alterniflora. Therefore, the distance between the first removal tentacle 3111 and the second removal tentacle 3121 is small. The third position is the falling position of Spartina alterniflora. After passing the second position, the Spartina alterniflora has been removed. When it reaches the third position, the clamping of the Spartina alterniflora is released, allowing the Spartina alterniflora to fall downwards to the collection plate 41 to complete the collection work. Therefore, a relatively large distance is also needed between the first removal tentacle 3111 and the second removal tentacle 3121. The first removal tentacle 3111 and the second removal tentacle 3121 in each of the above groups move cyclically in the above three positions to realize the entire cleaning process of Spartina alterniflora entering, removing and falling off.

[0057] In this embodiment, the first removal tentacle 3111 and the second removal tentacle 3121 have the same structure. Figure 6 As shown, the first removal tentacle 3111 and the second removal tentacle 3121 include a clamping part 31111, a guide rod 31112, and a connecting part 31113. The connecting part 31113 is connected to the transmission mechanism 32, specifically to the transmission chain 321, and thus moves with the transmission chain 321. One end of the guide rod 31112 is connected to the connecting part 31113, and the clamping part 31111 is adjustablely connected to the guide rod 31112.

[0058] In this embodiment, the clamping portion 31111 is a cone with a diameter that gradually decreases in the direction away from the connecting portion 31113. That is, the clamping portion 31111 has a cone-shaped structure. With the above arrangement, the clamping surface between the first removable tentacle 3111 and the second removable tentacle 3121 in a set is an inclined surface, which can improve the clamping effect on Spartina alterniflora.

[0059] In this embodiment, the clamping part 31111 has a central hole for fitting onto the guide rod 31112, and the clamping part 31111 is slidably connected to the guide rod 31112. During the process of the first pull-out tentacle 3111 and the second pull-out tentacle 3121 clamping the Spartina alterniflora, under the action of friction, the clamping part 31111 will gradually move towards the middle position along the guide rod 31112, that is, the clamping parts 31111 of the first pull-out tentacle 3111 and the second pull-out tentacle 3121 will gradually approach each other until the Spartina alterniflora is clamped.

[0060] In this embodiment, the axial projection of the end of the clamping portion 31111 of one of the first removal tentacles 3111 and the second removal tentacles 3121 away from the connecting portion 31113 is located within the connecting portion 31113 of the other, so that the connecting portion 31113 limits and stops the clamping portion 31111. That is, in extreme cases, for example, the clamping portion 31111 of the first removal tentacles 3111 may move a long distance, thereby moving to the end of the second removal tentacles 3121. At this time, due to the limiting stop of the connecting portion 31113 of the second removal tentacles 3121, the clamping portion 31111 of the first removal tentacles 3111 will not extend into the transmission chain 321 of the second removal member 312, thus avoiding affecting the operation of the second removal member 312.

[0061] In an optional embodiment, the guide rod 31112 can be a telescopic rod structure. Specifically, both ends of the guide rod 31112 are connected to the connecting part 31113 and the clamping part 31111, respectively. During the process of the first pull-out tentacle 3111 and the second pull-out tentacle 3121 clamping the Spartina alterniflora, under the action of friction, the clamping part 31111 will gradually move towards the middle position, thereby causing the guide rod 31112 to extend.

[0062] In this embodiment, as Figures 1 to 2 As shown, the pull-out Spartina alterniflora removal device also includes a height adjustment component 50. The height adjustment component 50 is disposed on the frame 10 and drivenly connected to the pull-out component 30, and is used to adjust the height of the pull-out component 30.

[0063] Specifically, such as Figures 3 to 5 As shown, the height adjustment assembly 50 includes two first rotating arms 51, which are rotatably mounted on both sides of the front end of the frame 10. The first removal component 311 and the second removal component 312 of the removal assembly 30 are rotatably connected to the two first rotating arms 51, respectively. Specifically, the rear ends of the first transmission housing 3112 and the second transmission housing 3122 are rotatably connected to the two first rotating arms 51, respectively. The first rotating arms 51 rotate up and down, thereby adjusting the overall height of the removal assembly 30.

[0064] In this embodiment, as Figures 3 to 5As shown, the removal assembly 30 also includes two second rotating arms 34, which are rotatably mounted on both sides of the retractor 33 and rotatably connected to the first removal member 311 and the second removal member 312, respectively. Specifically, the two second rotating arms 34 are rotatably connected to the front ends of the first transmission housing 3112 and the second transmission housing 3122, respectively. The second rotating arms 34 rotate up and down to adjust the height of the retractor 33.

[0065] In this embodiment, when the removal component 30 is running, according to the actual application scenario, the first rotating arm 51 first adjusts the overall height of the removal component 30, and then the second rotating arm 34 adjusts the height of the collector 33. The collector 33 rotates to collect the Spartina alterniflora plants into the removal mechanism 31. Finally, driven by the transmission chain 321, the Spartina alterniflora plants that have entered the removal mechanism 31 are removed by the pair of first removal tentacles 3111 and second removal tentacles 3121.

[0066] like Figures 3 to 5 As shown, the collector 33 is provided with multiple tooth structures 331 spaced circumferentially, and the tooth structures 331 are provided with multiple teeth 3311 spaced axially. Each tooth 3311 includes a first segment and a second segment set at an obtuse angle, and the bending direction of the tooth 3311 faces the frame 10. That is, the bending opening of the tooth 3311 faces the rear end. This arrangement buffers the Spartina alterniflora, preventing it from detaching downwards from the tooth 3311, thereby improving control efficiency.

[0067] In this embodiment, with Figure 5 Taking the angle shown as an example, the direction of rotation of the collector 33 is counterclockwise, thereby collecting the Spartina alterniflora plant from below into the removal mechanism 31.

[0068] like Figures 3 to 5 As shown, the removal assembly 30 also includes a crossbeam 35. The two ends of the crossbeam 35 are connected to the first transmission housing 3112 and the second transmission housing 3122, respectively, thereby improving the overall structural strength of the removal mechanism 31.

[0069] In this embodiment, the traveling component 20 includes a tracked traveling structure. By adopting a tracked traveling structure, the contact area between the traveling component 20 and the muddy tidal flat can be increased, preventing the cleaning device from getting stuck in the mud due to its own weight.

[0070] Furthermore, in this embodiment, the frame 10 also includes a float assembly for providing buoyancy for the pull-out Spartina alterniflora removal device. Specifically, the float assembly includes multiple hollow floats, which can be disposed around the periphery of the frame 10. Through the above arrangement, the pull-out Spartina alterniflora removal device in this embodiment is suitable for operations in wet tidal flats. The float assembly can improve the buoyancy of the removal device, thereby avoiding the problems of operating in waterlogged areas or sinking into deep pits as a condition for tidal flat operations.

[0071] In this embodiment, the pull-out Spartina alterniflora removal device also includes a vision sensor. The vision sensor is located at the front end of the frame 10 and is used to acquire image information in front of the pull-out Spartina alterniflora removal device.

[0072] In this embodiment, the pull-out Spartina alterniflora removal device also includes a distance measuring module. The distance measuring module is located at the front end of the frame 10 and is used to measure the distance to the Spartina alterniflora. Specifically, the distance measuring module can be a laser distance measuring module or other types of distance measuring modules.

[0073] In this embodiment, the pull-out Spartina alterniflora removal device also includes a controller. The controller is electrically connected to the aforementioned pull-out component, height adjustment component, drive mechanism, vision sensor, and distance measuring module, thereby achieving automatic control of the pull-out Spartina alterniflora removal device. The controller, through the vision sensor and distance measuring module, can identify the position and tilt angle of the Spartina alterniflora plant in real time, thus accurately guiding the gripping tentacles for targeted pull-out, improving operational accuracy. The entire gripping and pull-out process, combined with angle / height control and force feedback systems, achieves smooth pull-out, avoiding broken stems and roots.
