Description

Technical Field

[0001] The invention relates to the technical field of ecological protection engineering construction, and in particular to a terrain transformation device and method for an abandoned breeding pond ecological protection engineering project. Background Art

[0002] In the construction of ecological protection projects, in order to meet the needs of bird habitats, it is usually necessary to transform abandoned breeding ponds into an ecological environment suitable for bird habitats. However, traditional abandoned breeding ponds often contain a large number of Spartina alterniflora. This invasive plant not only occupies the water space, but also destroys the ecological balance and seriously affects the habitat and foraging of birds. Therefore, in the transformation process, it is necessary to first completely remove Spartina alterniflora, and then carry out terrain transformation to construct diversified habitats such as ecological islands, shallows, deep water areas, etc. suitable for bird habitats.

[0003] At present, some transformation methods usually involve digging out Spartina alterniflora through excavation equipment, and then transforming the terrain through excavation equipment. However, in actual operation, a large amount of soil will be dug out when digging out Spartina alterniflora, which makes the subsequent treatment of Spartina alterniflora more troublesome and leads to a waste of soil resources, affecting the accuracy and effect of subsequent terrain transformation. For this reason, we propose a terrain transformation device and method for abandoned aquaculture pond ecological protection engineering. Summary of the invention

[0026] A method for terrain transformation of an ecological protection project for abandoned aquaculture ponds, using the above transformation device, includes the following steps:

[0027] S1: Dig out Spartina alterniflora in the abandoned aquaculture pond through the transformation mechanism and make it enter the processing component for processing;

[0028] S2: The Spartina alterniflora falls on the first filter screen on the rotating seat. The soil in the Spartina alterniflora passes through the first filter screen and enters the soil flow cavity, and then is discharged into the abandoned aquaculture pond through the soil discharge pipe. The rotating device two is used to drive the rotating seat to rotate so that the first filter screen corresponds to the crushing cavity, and the Spartina alterniflora enters the crushing cavity by the rotation of the first filter screen;

[0029] S3: Crush the Spartina alterniflora that enters through the crushing roller assembly, and discharge the crushed Spartina alterniflora into the abandoned aquaculture pond through the discharge pipe;

[0030] S4: After treating the Spartina alterniflora in the abandoned aquaculture pond, treat the soil in the abandoned aquaculture pond and transform the terrain through the transformation mechanism.

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

[0032] 1) The present invention can dig up the Spartina alterniflora by its roots through the transformation mechanism, separate the dug-out Spartina alterniflora and soil through the treatment component, crush the Spartina alterniflora, and lay the separated soil and crushed Spartina alterniflora back into the abandoned aquaculture pond. This not only reduces the waste of soil resources, avoids affecting the accuracy and effect of subsequent terrain transformation, but also improves soil fertility and the quality of subsequent transformation of the abandoned aquaculture pond. After cutting off the Spartina alterniflora, the soil can be treated and the terrain can be transformed through the transformation mechanism, which is convenient to use, simple in process, short in time-consuming, and low in use cost;

[0033] 2) The present invention uses a crushing roller assembly to crush the Spartina alterniflora. When an obstacle causes the rotating shaft to rotate relative to the outer sleeve, the movable block can drive the arc rack, the arc rack drives the gear part, and the gear part drives the transmission rod to make the rotating ring rotate. When the rotating ring rotates, the crushing blade is driven to reciprocate through the arc protrusion. The crushing blade can better cut the obstacle through the rotational force and the shearing force of the reciprocating motion. If it is still affected by the obstacle, the movable block will move and press the pressure sensor, and the pressure sensor controls the rotation device three to close and the external alarm to open to remind the user to avoid damage to the crushing roller assembly;

[0034] 3) The earth-digging head in the transformation mechanism of the present invention is also provided with a soil discharge port, a winding roller, a vibrator one, a shielding cloth and a winding device. The shielding cloth can be controlled through the winding device so that the movable port on it corresponds to or is staggered from the soil discharge port. When the two correspond, part of the soil can be discharged from the soil discharge port, reducing the processing burden of the subsequent processing component and further reducing the waste of soil resources. When the two are separated and the soil can be normally treated and the terrain can be transformed, the soil will not be discharged from the soil discharge port, improving the flexibility of the device.

[0042] Next, the technical solutions in the embodiments of the present invention will be clearly and completely described in conjunction with the accompanying drawings in the embodiments of the present invention. Obviously, the described embodiments are only a part of the embodiments of the present invention, rather than all the embodiments. Based on the embodiments of the present invention, all other embodiments obtained by those of ordinary skill in the art without creative efforts shall fall within the protection scope of the present invention.

[0043] Embodiment 1

[0044] Please refer to the attached Figure 1 - attached Figure 2 , a terrain transformation device for an ecological protection project of abandoned aquaculture ponds, including a transformation mechanism 3 and a processing component 4. The transformation mechanism 3 is used for Spartina alterniflora or soil in the abandoned aquaculture ponds, and the processing component 4 is used for processing the dug Spartina alterniflora;

[0045] Among them, the device separates the dug Spartina alterniflora from the soil it carries through the processing component 4, and then processes the Spartina alterniflora. The processing component 4 includes:

[0046] The housing 41 has a hollow top. A guiding partition block 42 is provided in its inner cavity. The guiding partition block 42 divides the inner cavity of the housing 41 into a soil flow cavity 43 and a crushing cavity 44. The soil flow cavity 43 is connected with a soil discharge pipe 46. The guiding partition block 42 is in the shape of a right trapezoid, and its inclined surface is located in the soil flow cavity 43 so as to guide the incoming soil 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 is re-laid back to the abandoned aquaculture pond. The side wall of the crushing cavity 44 is connected with a discharge pipe, and crushing roller assemblies 48 for crushing Spartina alterniflora are symmetrically arranged in the crushing cavity 44. The crushed Spartina alterniflora can be re-laid back to the abandoned aquaculture pond through the discharge pipe, improving the soil fertility and enhancing the subsequent renovation quality of the abandoned aquaculture pond.

[0047] The rotating seat 47 is arranged in the housing 41 and above the guiding partition block 42. An opening is provided on one side of the rotating seat 47, and a first filter screen 49 for filtering soil is rotatably arranged in the opening. The rotating seat 47 is driven to rotate by a second rotating device 411 embedded in the guiding partition block 42 so that the first filter screen 49 corresponds to the soil flow cavity 43 or the crushing cavity 44. The second rotating device 411 includes, for example, a servo motor and a reducer. When the excavated Spartina alterniflora and soil are put into the housing 41, the Spartina alterniflora and soil are placed on the first filter screen 49. The soil enters the soil flow cavity 43 through the first 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 second rotating device 411 so that the first filter screen 49 corresponds to the crushing cavity 44, and the first filter screen 49 is controlled to rotate to an inclined state so that the Spartina alterniflora on the first filter screen 49 enters the crushing cavity 44.

[0048] An ecological protection project terrain renovation method for an abandoned aquaculture pond, using the above renovation device, includes the following steps:

[0049] S1: The Spartina alterniflora in the abandoned aquaculture pond is dug out by the renovation mechanism 3 and enters the treatment assembly 4 for treatment;

[0050] S2: The Spartina alterniflora falls on the first filter screen 49 on the rotating seat 47. The soil in the Spartina alterniflora passes through the first filter screen 49 and enters the soil flow cavity 43, and then is discharged into the abandoned aquaculture pond from the soil discharge pipe 46. The rotating seat 47 is driven to rotate by the second rotating device 411 so that the first filter screen 49 corresponds to the crushing cavity 44, and the Spartina alterniflora enters the crushing cavity 44 by the rotation of the first filter screen 49;

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

[0052] S4: After the Spartina alterniflora in the abandoned aquaculture pond is processed, the soil in the abandoned aquaculture pond is processed and the terrain is renovated by the renovation mechanism 3;

[0053] For example, the following transformation methods are adopted:

[0054] Ecological islands (bird refuges), shoals (foraging areas for wading birds), open waters (foraging areas for deep-water waterfowl and shallow-water waterfowl), deep water areas (fish refuges) and

[0055] In ecological isolation areas (external ditches and embankments), the elevation in terrain design is relative elevation, with the embankment as 0.0m elevation, and the unit is m;

[0056] Ecological island: The shape is kidney-shaped. The S-shaped water-land ecotone of the ecological island provides a larger foraging area for birds and can be connected to the low embankment on the side of the river. The bank slope is about 1:10, and a landform with a gradual transition of water, shoals, gentle slopes and earth mounds is formed around the island. A row of wooden stakes (about 50) are set up on the ecological island and its surroundings for herons and gulls to rest. The spacing is about 1m. The length of the wooden stakes is 4m and the diameter of the big head is 20cm.

[0057] Shallow terrain: The shallows around the ecological island and the shallows along the low embankments on the river side are in a shallow saucer shape, with a bank slope of about 1:8, the gentlest bank slope of about 1:20, and a water depth of no more than 0.3m, accounting for a large proportion of the total water area;

[0058] Deepwater terrain: constructed around the seawall and wind turbine foundation piles, with a water depth of 2-2.5m and a slope of about 1:5 after the transformation. This area is a safe haven for fish and an important wintering ground for fish in winter;

[0059] Open water terrain: The base elevation of the open water surface is relatively flat, the water body is relatively still or the flow is relatively slow compared to the river. The water depth in the shallow waterfowl foraging area is 0.3-0.8m, and the water depth in the deep waterfowl foraging area 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 the Spartina alterniflora in the abandoned breeding pond area, the soil in the abandoned breeding pond area is excavated, landfilled and leveled to form the above-mentioned ecological island, shoal terrain, etc., while the introduction or discharge of water into the abandoned breeding pond area does not require the transformation of this device. The water source in the abandoned breeding pond area can be extracted before construction, and water can be injected into it after construction.

[0061] Example 2

[0062] Please see attached Figure 1 -Attached Figure 3On the basis of Example 1, one end of the filter screen 49 of this embodiment is rotatably connected to the inner wall of one side of the through-hole through a rotating shaft member, the rotating shaft member includes a rotating shaft seat and a rotating shaft, the rotating shaft member is driven by a rotating device 410 arranged on the rotating seat 47 to drive the filter screen 49 to flip, 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 member are connected by a bevel gear set (two sets of meshing bevel gears), the top of the rotating seat 47 is integrated with an inclined convex edge on one side away from the through-hole, 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, and the rotating seat 47 is embedded with a vibrator 2 412, which belongs to the conventional structure in the field;

[0063] When the Spartina alterniflora is on the filter screen 49, the rotating seat 47 is vibrated by turning on the vibrator 412, so that the soil in the Spartina alterniflora passes through the filter screen 49 and is separated from the Spartina alterniflora; after removing the soil, the rotating seat 47 is rotated so that the filter screen 49 corresponds to the crushing chamber 44, and the filter screen 49 is driven to flip and tilt through the rotating device 410, so that the Spartina alterniflora located on the filter screen 49 enters the crushing chamber 44.

[0064] Preferably, a fixing block 415 is inserted into the other end of the filter screen 1 49 of the present embodiment, a fixing groove for inserting the fixing block 415 is opened at one end of the filter screen 1 49, the other end of the fixing block 415 is movably inserted into the groove body opened on the inner wall of the through opening, and the fixing block 415 and the groove bottom of the groove body are connected by an elastic member (such as a spring), a winding shaft is rotatably arranged in the groove body, and one end of the winding shaft passes through the bottom wall of the rotating seat 47 and is connected to a gear 1 417, the gear 1 417 is meshed with the gear 2 418, the gear 2 418 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 2 418 does not rotate, and a pull rope 416 is wound on the outer wall of the winding shaft, and 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 1 49 corresponds to the crushing chamber 44, the winding shaft winding rope 416 is driven by the gear 1 417 and the gear 2 418 to pull the fixed block 415 into the tank body;

[0066] When the rotating seat 47 rotates, the gear 1 417 drives the winding shaft to rotate and reel in the pull rope 416 under the action of the gear 2 418. The pull rope 416 pulls the fixed block 415 into the trough body, and then drives the filter screen 49 to flip through the rotating device 1 410; when the rotating seat 47 rotates and resets, the fixed block 415 is reset under the action of the elastic member so that one end of the filter screen 49 is inserted into the fixed groove of the filter screen 49. In this way, the strength of the filter screen 49 in bearing the Spartina alterniflora and soil when corresponding to the soil flow cavity 43 is improved, the burden of the rotating device 410 is reduced, and its service life is extended.

[0067] Example 3

[0068] Please refer to the attached Figure 2 - attached Figure 4 , on the basis of Example 1, a second filter screen 414 for filtering Spartina alterniflora is provided in the crushing chamber 44 below the crushing roller assembly 48 in this example. One end of the second filter screen 414 is hinged to the guiding and separating block 42, and the other end is fixed by a fixing member inserted into the outer wall of the housing 41. The fixing member can be a snap pin or a bolt, etc. By removing the fixing member, the second filter screen 414 can be rotated downward to facilitate the cleaning of the second filter screen 414 or the crushing roller assembly 48. In order to better clean this place, a housing door (not shown in the figure) is provided at the corresponding position on the outer wall of the housing 41. A heating member 45 is provided in the crushing chamber 44 below the second filter screen 414. The heating member 45 is, for example, a heating rod, a heating wire or other similar heating components. The crushed Spartina alterniflora is heated by the heating member 45 to generate high temperature, so as to destroy the cell structure and biological activity of Spartina alterniflora, especially the regeneration ability of its seeds and rhizome parts, thereby effectively preventing it from growing again after being laid back into the soil;

[0069] The two crushing roller assemblies 48 are connected by a gear set (not shown in the figure, the gear set is two meshing gears), so that the two crushing roller assemblies 48 rotate synchronously in opposite directions. Specifically, as shown in the attached Figure 2 , 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 a third rotating device (not shown in the figure, such as a motor). A stirring member 413 is provided in the crushing chamber 44 below the second filter screen 414. The shaft portion of the stirring member 413 is connected to the output end of the third rotating device by transmission. A sprocket transmission group (not shown in the figure, the sprocket transmission group includes sprockets and chains) can be used. The above-mentioned gear set, the third rotating device and the sprocket transmission group are all installed on the outer side wall of the housing 41. When the crushing roller assembly 48 crushes Spartina alterniflora, it drives the stirring member 413 at the same time, and the stirring member 413 stirs the crushed Spartina alterniflora to make it evenly heated by high temperature.

[0071] Example 4

[0072] Please refer to the attached Figure 2 - attached Figure 4 , on the basis of Example 3, the crushing roller assembly 48 in this example includes:

[0073] The rotating shaft 481 is rotatably arranged in the crushing chamber 44. The end of the rotating shaft 481 penetrates through the housing 41. Both the gear set and the rotating device three are connected to the rotating shaft 481. An outer sleeve 482 is sleeved outside it. Support blocks are fixedly arranged on both the inner wall of the outer sleeve 482 and the outer wall of the rotating shaft 481. An annular cavity 486 is formed in the outer sleeve 482. A rotating ring 487 coaxial with the rotating shaft 481 is rotatably arranged in the annular cavity 486. A plurality of groups of arc-shaped protrusions 488 are arranged on the circumferential outer wall of the rotating ring 487;

[0074] A plurality of groups of crushing blades 489 are movably inserted into the outer wall of the outer sleeve 482 in an annular array. One end of the crushing blade 489 extends into the annular cavity 486 and is in sliding contact with the rotating ring 487. A ball in sliding contact with the rotating ring 487 is embedded at one end of the crushing blade 489. 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 member (such as a spring);

[0075] An arc-shaped connecting member is arranged between the two 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 will be dug out when digging out Spartina alterniflora, and there may be stones in the soil. Although a certain amount of stones and soil can be filtered out when passing through the first filter screen 49, there is still a possibility that some larger stones enter the crushing chamber 44 along with the Spartina alterniflora. Therefore, during crushing, when the rotating device three works, the rotating shaft 481 drives the arc-shaped connecting member, and the arc-shaped connecting member drives the outer sleeve 482 to rotate, and then the Spartina alterniflora is crushed and cut by the crushing blade 489. If the crushing blade 489 contacts an obstacle (unfiltered stone or other large particles), it will cause the outer sleeve 482 to be unable to rotate. Then the rotating shaft 481 will rotate relative to the outer sleeve 482, causing the arc-shaped connecting member to drive the rotating ring 487 to rotate. Then the rotating ring 487 intermittently pushes the crushing blade 489 through the arc-shaped protrusion 488, causing the crushing blade 489 to move reciprocally. The crushing blade 489 can better cut the obstacle through the rotational force and the shearing force of the reciprocating motion, so that the outer sleeve 482 can be continuously driven by the rotating shaft 481 and the arc-shaped connecting member to rotate for crushing work.

[0077] Preferably, the arc-shaped connecting member of this embodiment includes:

[0078] An arc-shaped plate 483, one end of which is connected to the support block on the rotating shaft 481, and the other end extends into the arc-shaped seat 484 and is provided with a movable block. The movable block and the inner wall of the arc-shaped seat 484 are connected by an elastic member (such as a spring). It should be noted that the arc-shaped plate 483 and the arc-shaped seat 484 correspond to the reverse rotation directions of the outer sleeve 482 and the rotating shaft 481 they are in to attach 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-shaped plate 483 and the arc-shaped seat 484. When the outer sleeve 482 is blocked and unable to rotate, the rotating shaft 481 drives the arc-shaped plate 483 to move the movable block in the arc-shaped seat 484 to squeeze the elastic member;

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

[0080] When the arc-shaped plate 483 moves the movable block in the arc-shaped seat 484 to squeeze the elastic member, it also causes the arc-shaped rack to drive the gear member, the gear member drives the transmission rod 485, and the transmission rod 485 drives the rotating ring 487 to rotate.

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

[0082] If the blocking object is a stone that cannot be chopped, non-removal will cause jamming. Therefore, as the rotating shaft 481 drives the arc-shaped plate 483 to continuously move the movable block in the arc-shaped seat 484 and then squeeze the pressure sensor 4810, the pressure sensor 4810 will send a signal to the external controller, causing the external controller to control the rotating device three to stop working and the external alarm to sound, preventing the crushing blade 489 from being damaged. Subsequently, the user can open the shell door to process the stone at the filter screen two 414.

[0083] Embodiment 4

[0084] Please refer to the attached Figure 5 , on the basis of Embodiment 1, the transformation mechanism 3 of this embodiment includes:

[0085] The digging head 31 has a bottom wall with a plurality of discharge ports 32 for discharging soil. A cavity is provided on the bottom wall of the digging head 31 and located on one side of the discharge port 32. A winding roller 33 is provided in the cavity to rotate via an elastic rotating shaft (including a rotating shaft and a torsion spring). A shielding cloth 35 for shielding the discharge port 32 is wound on the outer wall of the winding roller 33. The shielding cloth 35 is made of a highly wear-resistant material, such as polyester, polypropylene, etc. The other end of the shielding cloth 35 passes through the side wall of the digging head 31 and is connected to a winding device 36 (including, for example, a motor and a roller body). A movable opening is provided on the outer wall of the shielding cloth 35 and in an area offset from the discharge port 32. The winding device 36 and the elastic rotating shaft cooperate to control the shielding cloth 35 so that the movable opening of the shielding cloth 35 corresponds to or is offset from the discharge port 32, so as to attach Figure 6 As shown, the shielding cloth 35 is unwound by the winding device 36, and then the winding roller 33 reels 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 opening 32. At this time, when the digging head 31 digs out the Spartina alterniflora, the excavated soil can be discharged from the soil discharge opening 32 through the movable opening and the discharge opening, thereby reducing the processing burden of the subsequent processing component 4; and when the soil is simply transformed after removing the Spartina alterniflora, the shielding cloth 35 can be reeled in by the winding device 36, so that the movable opening of the shielding cloth 35 is staggered with the soil discharge opening 32, thereby preventing the entered soil from being discharged from the soil discharge opening 32, so that it can be transferred to the desired position with the movement of the digging head 31;

[0086] It should be noted that a plurality of guide rollers for guiding the shielding cloth 35 are provided in the digging head 31 , and the guide rollers limit the shielding cloth 35 from contacting the bottom wall of the digging head 31 .

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