Description

Technical Field

[0001] This invention relates to the field of ecological protection engineering construction technology, specifically to a device and method for terrain modification in ecological protection engineering of abandoned aquaculture ponds. Background Technology

[0002] In the construction of ecological protection projects, in order to meet the needs of bird habitats, it is usually necessary to transform abandoned aquaculture ponds into ecological environments suitable for birds. However, traditional abandoned aquaculture ponds often contain a large number of Spartina alterniflora. This invasive plant not only occupies water space but also disrupts the ecological balance, seriously affecting birds' habitat and foraging. Therefore, in the transformation process, it is necessary to first completely remove Spartina alterniflora and then carry out terrain modification to create diverse habitats such as ecological islands, shallow beaches, and deep water areas suitable for birds.

[0003] Currently, some methods of land reclamation typically involve excavating Spartina alterniflora using digging equipment, followed by land reclamation using the same equipment. However, in practice, excavating Spartina alterniflora often involves digging up a large amount of soil, making subsequent treatment of the Spartina alterniflora more complicated and wasting soil resources. This also affects the accuracy and effectiveness of subsequent land reclamation. Therefore, we propose a land reclamation device and method for ecological protection projects of abandoned aquaculture ponds. Summary of the Invention

[0004] The purpose of this invention is to provide a terrain modification device and method for ecological protection projects of abandoned aquaculture ponds, so as to solve the problems mentioned in the background art.

[0005] To achieve the above objectives, the present invention provides the following technical solution:

[0006] A terrain modification device for ecological protection of abandoned aquaculture ponds includes a modification mechanism and a processing component. The modification mechanism is used to excavate Spartina alterniflora or soil from the abandoned aquaculture ponds, and the processing component is used to process the excavated Spartina alterniflora.

[0007] The processing component includes:

[0008] The shell has a guide partition block in its inner cavity, which divides the inner cavity of the shell into a soil flow chamber and a crushing chamber. The soil flow chamber is connected to a soil discharge pipe, and the side wall of the crushing chamber is connected to a material discharge pipe. The crushing chamber is symmetrically equipped with crushing roller assemblies for crushing Spartina alterniflora.

[0009] A rotating seat is located inside the housing and above the guide partition block. An opening is provided on one side of the rotating seat, and a filter screen for filtering soil is rotatably installed inside the opening. The rotating seat is driven to rotate by a rotating device embedded in the guide partition block so that the filter screen corresponds to the soil flow chamber or the crushing chamber.

[0010] A further improvement is that the modified mechanism includes:

[0011] The excavation head has several sets of discharge ports on its bottom wall for discharging soil. A cavity is formed on the bottom wall of the excavation head on one side of the discharge ports. A winding roller is rotatably mounted in the cavity via an elastic rotating shaft. A shielding cloth for covering the discharge ports is wound around the outer wall of the winding roller. The other end of the shielding cloth passes through the side wall of the excavation head and is connected to the winding device. An movable opening is formed on the outer wall of the shielding cloth in an area offset from the discharge ports. The winding device and the elastic rotating shaft work together to control the shielding cloth so that the movable opening of the shielding cloth corresponds to or is offset from the discharge ports.

[0012] Vibrator 1, located inside the cavity, is used to drive the excavator head to vibrate.

[0013] A further improvement is that one end of the filter screen is rotatably connected to the inner wall of the opening via a rotating shaft. The rotating shaft is driven by a rotating device on a rotating seat to rotate the filter screen. The top of the rotating seat is integrally provided with an inclined convex edge on the side away from the opening, and the lower end of the inclined convex edge corresponds to the filter screen. A vibrator is embedded in the rotating seat.

[0014] A further improvement is that a fixing block is inserted at the other end of the filter screen, and the other end of the fixing block is movably inserted into a groove opened in the inner wall of the opening. The fixing block and the bottom of the groove are connected by an elastic element. A winding shaft is rotatably provided in the groove, and one end of the winding shaft passes through the rotating seat and is connected to a gear. The gear and gear 2 mesh. The gear 2 is connected to the guide partition block through a bracket and is on the same axis as the center of the rotating seat. A pull rope is wound around the outer wall of the winding shaft, and one end of the pull rope is connected to the fixing block.

[0015] When the rotating seat rotates so that the filter screen corresponds to the crushing chamber, the winding shaft is driven by gear one and gear two to wind the pull rope and pull the fixed block into the tank.

[0016] A further improvement is that a second filter screen for filtering Spartina alterniflora is provided in the crushing chamber below the crushing roller assembly, and a heating element is provided in the crushing chamber below the second filter screen.

[0017] The two sets of crushing roller assemblies are connected by a gear set for transmission. One of the crushing roller assemblies is connected to the output end of the rotating device three. A stirring element is provided in the crushing chamber below the filter screen two. The shaft of the stirring element is connected to the output end of the rotating device three for transmission.

[0018] A further improvement is that the crushing roller assembly includes:

[0019] A rotating shaft is rotatably disposed within the crushing chamber, and an outer sleeve is fitted around its outer side. Support blocks are fixedly provided on the inner wall of the outer sleeve and the outer wall of the rotating shaft. An annular cavity is provided inside the outer sleeve, and a rotating ring coaxial with the rotating shaft is rotatably disposed within the annular cavity. Several sets of arc-shaped protrusions are provided on the outer circumference of the rotating ring.

[0020] Several sets of crushing blades are movably inserted into the outer wall of the outer sleeve in a ring array, and one end of the crushing blade extends into the annular cavity and slides against the rotating ring. The crushing blade is driven to move by the arc-shaped protrusion when the rotating ring rotates. The crushing blade and the inner wall of the annular cavity are connected by an elastic element.

[0021] An arc-shaped connector, located between two sets of support blocks, is used to drive the rotating ring to rotate when the rotating shaft rotates relative to the outer sleeve.

[0022] A further improvement is that the arc-shaped connector includes:

[0023] An arc-shaped plate has one end connected to a support block on a rotating shaft, and the other end extends into an arc-shaped seat and is equipped with a movable block. The movable block and the inner wall of the arc-shaped seat are connected by an elastic element. The end of the arc-shaped seat away from the arc-shaped plate is connected to a support block on an outer sleeve. A channel is opened in the support block on the outer sleeve, and a gear is rotatably inserted in the channel. The movable block is connected to an arc-shaped rack coaxial with the arc-shaped seat, and one end of the arc-shaped rack extends into the channel and meshes with the gear. The shaft of the gear is driven by a transmission rod, and one end of the transmission rod extends into an annular cavity and is driven by a rotating ring.

[0024] A further improvement is that the inner wall of the arc-shaped seat is provided with a pressure sensor for contacting the movable block. The pressure sensor is electrically connected to an external controller, and the external controller is electrically connected to the rotating device and an external alarm.

[0025] A further improvement is that the modification mechanism and the processing components are both located on the vehicle body, and the vehicle body is also equipped with an adjustment arm mechanism for adjusting the angle of the modification mechanism.

[0026] A method for terrain modification in an ecological protection project of abandoned aquaculture ponds, utilizing the aforementioned modification device, includes the following steps:

[0027] S1: The modified mechanism excavates Spartina alterniflora from the abandoned aquaculture pond and processes it in the treatment unit;

[0028] S2: Spartina alterniflora falls onto the filter screen one on the rotating seat. The soil in the Spartina alterniflora passes through the filter screen one and enters the soil flow chamber. Then it is discharged from the soil discharge pipe into the abandoned breeding pond. The rotating seat is driven by the rotating device two to rotate, so that the filter screen one corresponds to the crushing chamber. The rotation of the filter screen one causes the Spartina alterniflora to enter the crushing chamber.

[0029] S3: The incoming Spartina alterniflora is crushed by the crushing roller assembly, and the crushed Spartina alterniflora is discharged into the abandoned aquaculture pond through the discharge pipe;

[0030] S4: After treating the Spartina alterniflora in the abandoned aquaculture ponds, the soil and terrain in the abandoned aquaculture ponds are treated and modified by the modification agency.

[0031] Compared with the prior art, the beneficial effects of the present invention are:

[0032] 1) This invention can dig up Spartina alterniflora by the roots through a modified mechanism, and separate the dug-up Spartina alterniflora from the soil through a processing component. The Spartina alterniflora is then crushed, and the separated soil and crushed Spartina alterniflora are laid back on the abandoned aquaculture pond. This not only reduces the waste of soil resources and avoids affecting the accuracy and effect of subsequent terrain modification, but also improves soil fertility and enhances the quality of subsequent modification of the abandoned aquaculture pond. After cutting off Spartina alterniflora, the soil can be treated and the terrain modified through the modification mechanism. It is convenient to use, has a simple process, is short in time, and has low operating costs.

[0033] 2) This invention uses a crushing roller assembly to crush Spartina alterniflora. When an obstruction occurs, causing the rotating shaft to rotate relative to the outer sleeve, the movable block drives the arc-shaped rack, which in turn drives the gear assembly. The gear assembly drives the transmission rod, causing the rotating ring to rotate. When the rotating ring rotates, the arc-shaped protrusion drives the crushing blades to reciprocate. The crushing blades can better crush the obstruction through the rotational force and the shearing force of the reciprocating motion. If the obstruction still affects the operation, the movable block will move and press against the pressure sensor. The pressure sensor controls the rotating equipment to shut down and controls the external alarm to open to remind the user and prevent damage to the crushing roller assembly.

[0034] 3) The excavator head in the modified mechanism of the present invention is also equipped with a soil discharge port, a winding roller, a vibrator, a shielding cloth, and a winding device. The winding device can control the shielding cloth so that its movable opening is aligned with or offset from the soil discharge port. When they are aligned, the soil discharge port can discharge some soil, reducing the processing burden of subsequent processing components and further reducing the waste of soil resources. When they are separated, the soil can be processed normally and the terrain can be modified without soil being discharged from the soil discharge port, thus improving the flexibility of the device.

[0042] The technical solutions of the embodiments of the present invention will be clearly and completely described below with reference to the accompanying drawings. Obviously, the described embodiments are only some embodiments of the present invention, and not all embodiments. Based on the embodiments of the present invention, all other embodiments obtained by those skilled in the art without creative effort are within the scope of protection of the present invention.

[0043] Example 1

[0044] Please see the appendix Figure 1 - Appendix Figure 2 A terrain modification device for ecological protection of abandoned aquaculture ponds includes a modification mechanism 3 and a processing component 4. The modification mechanism 3 is used for Spartina alterniflora or soil in the abandoned aquaculture pond, and the processing component 4 is used for processing the dug-out Spartina alterniflora.

[0045] This device separates the dug-out Spartina alterniflora from the soil it carries through processing component 4, and then processes the Spartina alterniflora. Processing component 4 includes:

[0046] The shell 41 is hollow at the top and has a guide partition block 42 in its inner cavity. The guide partition block 42 divides the inner cavity of the shell 41 into a soil flow chamber 43 and a crushing chamber 44. The soil flow chamber 43 is connected to a soil discharge pipe 46. The guide partition block 42 is a right trapezoid with its inclined surface located inside the soil flow chamber 43 so that the soil entering is guided into the soil discharge pipe 46 for discharge. One end of the soil discharge pipe 46 extends to the outside of the vehicle body 1 so that the separated soil can be laid back on the abandoned aquaculture pond. The side wall of the crushing chamber 44 is connected to a discharge pipe, and the crushing chamber 44 is symmetrically equipped with crushing roller assemblies 48 for crushing Spartina alterniflora. The crushed Spartina alterniflora can be laid back on the abandoned aquaculture pond through the discharge pipe to improve soil fertility and improve the quality of subsequent transformation of the abandoned aquaculture pond.

[0047] A rotating seat 47 is located inside the housing 41 and above the guide partition block 42. A passage is opened on one side of the rotating seat 47, and a filter screen 49 for filtering soil is rotatably installed in the passage. The rotating seat 47 is driven to rotate by a rotating device 411 embedded in the guide partition block 42, so that the filter screen 49 corresponds to the soil flow chamber 43 or the crushing chamber 44. The rotating device 411 includes, for example, a servo motor and a reducer. When the dug-out Spartina alterniflora and soil are put into the housing 41, the Spartina alterniflora and soil are placed on the filter screen 49. The soil enters the soil flow chamber 43 through the filter screen 49 and is discharged from the soil discharge pipe 46. After the soil is discharged, the rotating seat 47 is driven to rotate by the rotating device 411, so that the filter screen 49 corresponds to the crushing chamber 44. The filter screen 49 is controlled to rotate to an inclined state, so that the Spartina alterniflora on the filter screen 49 enters the crushing chamber 44.

[0048] A method for terrain modification in an ecological protection project of abandoned aquaculture ponds, utilizing the aforementioned modification device, includes the following steps:

[0049] S1: The modified mechanism 3 digs out the Spartina alterniflora in the abandoned breeding pond and puts it into the processing component 4 for processing;

[0050] S2: Spartina alterniflora falls onto filter screen 49 on rotating seat 47. The soil in Spartina alterniflora passes through filter screen 49 and enters soil flow chamber 43. Then it is discharged from soil discharge pipe 46 into abandoned breeding pond. Rotating device 411 drives rotating seat 47 to rotate, so that filter screen 49 corresponds to crushing chamber 44. The rotation of filter screen 49 causes Spartina alterniflora to enter crushing chamber 44.

[0051] S3: The incoming Spartina alterniflora is crushed by the crushing roller assembly 48, and the crushed Spartina alterniflora is discharged into the abandoned aquaculture pond through the discharge pipe.

[0052] S4: After treating the Spartina alterniflora in the abandoned aquaculture pond, the soil and terrain in the abandoned aquaculture pond are treated and modified by the modification mechanism 3;

[0053] For example, the following modification methods can be adopted:

[0054] Ecological islands (bird refuge areas), shallow waters (wading bird foraging areas), open waters (deep-water waterfowl foraging areas and shallow-water waterfowl foraging areas), and deep-water areas (fish refuge areas) were excavated within the abandoned aquaculture ponds.

[0055] In the ecological isolation zone (external ditches and embankments), the elevation in the topographic design is a relative elevation, with the embankment as the 0.0m elevation, and the unit is meters.

[0056] Ecological Island: Kidney-shaped, the S-shaped water-land transition zone of the ecological island provides a larger foraging ground for birds and can be connected to the low dike on the side of the river; the bank slope is about 1:10, and the topography around the island is gradually transitioning from water, shallows, gentle slopes and mounds. A row of wooden stakes (about 50) is set up around the ecological island and its surroundings for herons and gulls to rest, with a spacing of about 1m. The wooden stakes are 4m long and 20cm in diameter at the larger end.

[0057] Shallow water topography: The shallow waters around the ecological island and along the low dikes on the side of the river are saucer-shaped with a bank slope of about 1:8. The gentlest bank slope is about 1:20. The water depth does not exceed 0.3m and accounts for a significant proportion of the total water area.

[0058] Deep water area topography: Constructed around the seawall and wind turbine foundation piles, the water depth after modification is 2-2.5m, and the slope is about 1:5. This area is a refuge area for fish and also an important overwintering ground for fish in winter.

[0059] Open water topography: The base elevation of open water surfaces is relatively flat, and the water is relatively still or the flow is slower than that of rivers. The water depth in shallow water foraging areas is 0.3-0.8m, while the water depth in deep water foraging areas is 0.8-1.2m.

[0060] Of course, it is not limited to the above-mentioned transformation method. It should also be noted that after removing Spartina alterniflora from the abandoned aquaculture pond area, the soil in the abandoned aquaculture pond area is excavated, filled, and leveled to transform it into the above-mentioned ecological island, shallow beach terrain, etc. However, the introduction or discharge of water sources into the abandoned aquaculture pond area does not require the transformation through this device. Water sources in the abandoned aquaculture pond area can be pumped out before construction and water sources can be injected into it after construction.

[0061] Example 2

[0062] Please see the appendix Figure 1 - Appendix Figure 3Based on Embodiment 1, in this embodiment, one end of filter screen 49 is rotatably connected to the inner wall of one side of the opening via a rotating shaft. The rotating shaft includes a rotating shaft seat and a rotating shaft. The rotating shaft is driven by a rotating device 410 mounted on a rotating seat 47 to rotate the filter screen 49. The rotating device 410 includes a servo motor and a reducer. The output end of the reducer and the rotating shaft in the rotating shaft are connected by a bevel gear set (two sets of meshing bevel gears). The top of the rotating seat 47 is integrally provided with an inclined convex edge on the side away from the opening, and the lower end of the inclined convex edge corresponds to the filter screen 49, so that the entering Spartina alterniflora and soil slide onto the filter screen 49 through the inclined convex edge. The rotating seat 47 is embedded with a vibrator 412, which is a conventional structure in the art.

[0063] When the Spartina alterniflora is on the filter screen 49, the vibrator 412 is turned on to make the rotating seat 47 vibrate, thereby causing the soil in the Spartina alterniflora to pass through the filter screen 49 and separate from the Spartina alterniflora. After the soil is removed, the rotating seat 47 rotates so that the filter screen 49 corresponds to the crushing chamber 44. The rotating device 410 drives the filter screen 49 to flip and tilt, so that the Spartina alterniflora on the filter screen 49 enters the crushing chamber 44.

[0064] Preferably, in this embodiment, a fixing block 415 is inserted into the other end of the filter screen 49. A fixing groove for the fixing block 415 to be inserted is opened at one end of the filter screen 49. The other end of the fixing block 415 is movably inserted into the groove opened in the inner wall of the opening. The fixing block 415 and the bottom of the groove are connected by an elastic element (e.g., a spring). A winding shaft is rotatably provided in the groove. One end of the winding shaft passes through the bottom wall of the rotating seat 47 and is connected to a gear 417. The gear 417 meshes with a gear 418. The gear 418 is connected to the guide partition block 42 through a bracket and is on the same axis as the center of the rotating seat 47. The gear 418 does not rotate. A pull rope 416 is wound around the outer wall of the winding shaft. One end of the pull rope 416 is connected to the fixing block 415.

[0065] When the rotating seat 47 rotates so that the filter screen 49 corresponds to the crushing chamber 44, the gear 417 and the gear 418 drive the winding shaft to wind the rope 416 and pull the fixed block 415 into the tank.

[0066] When the rotating seat 47 rotates, gear 417 drives the winding shaft to rotate and wind up the pull rope 416 under the action of gear 418. The pull rope 416 pulls the fixing block 415 into the groove, and then the rotating device 410 drives the filter screen 49 to flip. When the rotating seat 47 rotates to reset, the fixing block 415 resets under the action of the elastic element, so that one end of it is inserted into the fixing groove of the filter screen 49. In this way, the strength of the filter screen 49 in bearing Spartina alterniflora and soil when corresponding to the soil flow chamber 43 is improved, the burden on the rotating device 410 is reduced, and its service life is extended.

[0067] Example 3

[0068] Please see the appendix Figure 2 - Appendix Figure 4 Based on Embodiment 1, this embodiment has a second filter screen 414 for filtering Spartina alterniflora in the crushing chamber 44 below the crushing roller assembly 48. One end of the second filter screen 414 is hinged to the guide partition block 42, and the other end is fixed by a fastener inserted into the outer wall of the housing 41. The fastener can be a pin or bolt. By removing the fastener, the second filter screen 414 can be rotated downwards to clean the second filter screen 414 or the crushing roller assembly 48. In order to better clean this area, a door (not shown in the figure) is provided at the corresponding position on the outer wall of the housing 41. A heating element 45 is provided in the crushing chamber 44 below the second filter screen 414. The heating element 45 is, for example, a heating rod, a heating wire or other similar heating component. The heating element 45 generates high temperature to heat the crushed Spartina alterniflora, destroying the cell structure and biological activity of Spartina alterniflora, especially the regeneration ability of its seeds and rhizomes, thereby effectively preventing it from growing again after being laid back in the soil.

[0069] The two sets of crushing roller assemblies 48 are connected by a gear set (not shown in the figure, the gear set consists of two sets of meshing gears), so that the two sets of crushing roller assemblies 48 rotate synchronously in opposite directions. Specifically, see the attached diagram. Figure 2 As shown, the left crushing roller assembly 48 rotates clockwise, and the right crushing roller assembly 48 rotates counterclockwise.

[0070] One of the crushing roller assemblies 48 is connected to the output end of the rotating device three (not shown in the figure, for example, a motor). The crushing chamber 44 below the filter screen two 414 is equipped with a stirring element 413. The shaft of the stirring element 413 is connected to the output end of the rotating device three. A sprocket drive assembly (not shown in the figure, the sprocket drive assembly includes a sprocket and a chain) can be used. The aforementioned gear set, rotating device three and sprocket drive assembly are all installed on the outer wall of the housing 41. When the crushing roller assembly 48 crushes Spartina alterniflora, it simultaneously drives the stirring element 413. The stirring element 413 stirs the crushed Spartina alterniflora, so that it is evenly heated at high temperature.

[0071] Example 4

[0072] Please see the appendix Figure 2 - Appendix Figure 4 Based on Example 3, the crushing roller assembly 48 in this example includes:

[0073] A rotating shaft 481 is rotatably disposed within a crushing chamber 44. The end of the rotating shaft 481 passes through a housing 41. The gear set and the rotating device are all connected to the rotating shaft 481. An outer sleeve 482 is fitted on the outer side of the rotating shaft 481. Support blocks are fixedly provided on the inner wall of the outer sleeve 482 and the outer wall of the rotating shaft 481. An annular cavity 486 is opened inside the outer sleeve 482. A rotating ring 487 coaxial with the rotating shaft 481 is rotatably disposed inside the annular cavity 486. Several sets of arc-shaped protrusions 488 are provided on the outer circumference of the rotating ring 487.

[0074] Several sets of crushing blades 489 are movably inserted into the outer wall of the outer sleeve 482 in a ring array, and one end of the crushing blade 489 extends into the annular cavity 486 and slides against the rotating ring 487. One end of the crushing blade 489 is embedded with a ball that slides against the rotating ring 487. The crushing blade 489 is driven to move by the arc-shaped protrusion 488 when the rotating ring 487 rotates. The crushing blade 489 and the inner wall of the annular cavity 486 are connected by an elastic element (e.g., a spring).

[0075] An arc-shaped connector is located between two sets of support blocks and is used to drive the rotating ring 487 to rotate when the rotating shaft 481 rotates relative to the outer sleeve 482.

[0076] Considering that some soil may be unearthed when digging up Spartina alterniflora, and that this soil may contain stones, although filtering through the filter screen 49 can remove some stones and soil, there is still a possibility that some larger stones may enter the crushing chamber 44 along with the Spartina alterniflora. Therefore, during crushing, the rotating device 3, when working, causes the rotating shaft 481 to drive the arc-shaped connecting piece, which in turn drives the outer sleeve 482 to rotate, thereby crushing and cutting the Spartina alterniflora through the crushing blades 489. If the crushing blades 489 come into contact with obstructions (unfiltered stones), When large particles (or other large objects) are present, the outer sleeve 482 may become unable to rotate. Consequently, the rotating shaft 481 will rotate relative to the outer sleeve 482, causing the arc-shaped connector to drive the rotating ring 487 to rotate. The rotating ring 487 then intermittently pushes the crushing blade 489 through the arc-shaped protrusion 488, causing the crushing blade 489 to move back and forth. The crushing blade 489 can better cut up the obstruction through the rotational force and the shearing force of the reciprocating motion, so that the outer sleeve 482 can continue to be driven to rotate by the rotating shaft 481 and the arc-shaped connector to carry out the crushing work.

[0077] Preferably, the arc-shaped connector in this embodiment includes:

[0078] The arc-shaped plate 483 has one end connected to a support block on the rotating shaft 481, and the other end extends into the arc-shaped seat 484 and is equipped with a movable block. The movable block and the inner wall of the arc-shaped seat 484 are connected by an elastic element (e.g., a spring). It should be noted that the arc-shaped plate 483 and the arc-shaped seat 484 correspond to the opposite rotation of the outer sleeve 482 and the rotating shaft 481, so as to accommodate... Figure 4As shown, if the rotating shaft 481 rotates clockwise, the rotating shaft 481 causes the outer sleeve 482 to rotate clockwise through the arc plate 483 and the arc seat 484. When the outer sleeve 482 is blocked and cannot rotate, the rotating shaft 481 will drive the arc plate 483 to move the movable block in the arc seat 484 to compress the elastic element.

[0079] The end of the arc-shaped seat 484 away from the arc-shaped plate 483 is connected to a support block on the outer sleeve 482. The support block on the outer sleeve 482 has a channel, and a gear is rotatably inserted in the channel. The movable block is connected to an arc-shaped rack coaxial with the arc-shaped seat 484, and one end of the arc-shaped rack extends into the channel and meshes with the gear. The gear includes a gear meshing with the arc-shaped rack and a shaft sleeved at the center of the gear. The shaft of the gear is connected to a transmission rod 485. The shaft can be connected to the transmission rod 485 through a bevel gear set (two sets of meshing gears). One end of the transmission rod 485 extends into the annular cavity 486 and is connected to the rotating ring 487. The transmission rod 485 can be connected to the teeth on the outer wall of the rotating ring 487 through gear meshing. Of course, it is not limited to this transmission method.

[0080] When the arc plate 483 causes the movable block to move within the arc seat 484 and compress the elastic element, the arc rack simultaneously drives the gear component, which in turn drives the transmission rod 485, which in turn drives the rotating ring 487 to rotate.

[0081] Preferably, the inner wall of the arc-shaped seat 484 in this embodiment is provided with a pressure sensor 4810 for contacting the movable block. The pressure sensor 4810 is electrically connected to an external controller, and the external controller is electrically connected to the rotating device and an external alarm.

[0082] If the obstruction is an uncut stone, the inability to cut it will cause jamming. Therefore, as the rotating shaft 481 drives the arc plate 483, the moving block moves continuously within the arc seat 484 and presses against the pressure sensor 4810. The pressure sensor 4810 will send a signal to the external controller, causing the external controller to stop the rotating equipment and sound an external alarm to prevent damage to the crushing blade 489. Afterwards, the user can open the shell door to process the stone at the filter screen 414.

[0083] Example 4

[0084] Please see the appendix Figure 5 Based on Example 1, the modified mechanism 3 in this example includes:

[0085] The excavation head 31 has several sets of discharge ports 32 on its bottom wall for discharging soil. A cavity is formed on the bottom wall of the excavation head 31, located on one side of the discharge ports 32. A winding roller 33 is rotatably mounted within the cavity via an elastic rotating shaft (including the shaft and a torsion spring). A shielding cloth 35, made of a highly wear-resistant material such as polyester or polypropylene, is wound around the outer wall of the winding roller 33 to cover the discharge ports 32. The other end of the shielding cloth 35 penetrates the side wall of the excavation head 31 and is connected to a winding device 36 (including a motor and a roller). An movable opening is formed on the outer wall of the shielding cloth 35 in an area offset from the discharge ports 32. The winding device 36 and the elastic rotating shaft work together to control the shielding cloth 35, ensuring that the movable opening of the shielding cloth 35 corresponds to or is offset from the discharge ports 32, thus preventing soil from being discharged. Figure 6 As shown, the shielding cloth 35 is unwound by the winding device 36, and then the winding roller 33 winds up the shielding cloth 35 under the action of the elastic rotating shaft until the movable opening of the shielding cloth 35 corresponds to the soil discharge port 32. At this time, when the digging head 31 digs out Spartina alterniflora, the soil can be discharged from the soil discharge port 32 through the movable opening and the discharge port, reducing the processing burden of the subsequent processing component 4. When performing simple soil modification after removing Spartina alterniflora, the shielding cloth 35 can be wound up by the winding device 36 so that the movable opening of the shielding cloth 35 is staggered from the soil discharge port 32, so that the soil entering will not be discharged from the soil discharge port 32, so that it can be transferred to the required position as the digging head 31 moves.

[0086] It should be noted that the excavation head 31 is equipped with several sets of guide rollers for guiding the shielding cloth 35, and the guide rollers restrict the shielding cloth 35 from contacting the bottom wall of the excavation head 31.

[0087] Vibrator 34 is installed in the cavity to drive the excavation head 31 to vibrate. When the movable port corresponds to the discharge port 32, the vibrator 34 can be turned on to make the excavation head 31 vibrate to a certain extent, so that the soil can be discharged from the discharge port 32 better.
