Description

Technical Field

[0001] The present invention relates to the technical field of ecological environment transformation and restoration, and specifically to a multi-level habitat transformation and restoration device and method for coordinated tree, shrub, grass, terrestrial and aquatic activities. Background Art

[0002] At present, the construction of wind farms has had a certain impact on bird migration, and the land between wind turbines has not been fully utilized, resulting in a waste of land resources. In order to rationally utilize the land between wind turbines to facilitate the habitat of different birds, the ecological environment of the land needs to be transformed and restored. The traditional transformation and restoration method is to use equipment to dig holes in the land in the restoration area and plant plants. Although this method can achieve certain ecological restoration purposes, it has the following defects when used: it often only focuses on ecological restoration on land, while ignoring the restoration of water bodies, and the restoration effect needs to be improved. In addition, the land to be restored is usually wetland with saline soil. When the planting holes are dug by the equipment, water will leak into the dug planting holes, causing water accumulation in the planting holes. If drainage is not carried out, it is easy to cause the roots of the seedlings to rot after planting. When draining, independent pumping equipment is required, which is more troublesome to use. To this end, we propose a multi-level habitat transformation and restoration device and method for coordinated trees, shrubs, grasses, and terrestrial and aquatic plants. Summary of the Invention

DETAILED DESCRIPTION

[0036] The following will clearly and completely describe the technical solutions in the embodiments of the present invention in conjunction with the accompanying drawings. Obviously, the described embodiments are only part of the embodiments of the present invention, not all of the embodiments. Based on the embodiments of the present invention, all other embodiments obtained by ordinary technicians in this field without making creative efforts are within the scope of protection of the present invention.

[0037] Example 1

[0038] Please see the attached Figure 1 -Attached Figure 2 , a multi-level habitat reconstruction and restoration device that integrates trees, shrubs, grasses, terrestrial and aquatic plants, used to restore wetland areas;

[0039] The system comprises a mobile body 1, a land restoration unit arranged on the mobile body 1, and an aquatic organism delivery unit 4 connected to the mobile body 1, and the ecological environment of the restoration area is transformed and restored through the land restoration unit and the aquatic organism delivery unit 4;

[0040] The land restoration unit includes a sowing mechanism 2 for sowing herb seeds and a planting mechanism 3 for assisting in the planting of tree seedlings or shrub seedlings, which are provided on the mobile vehicle 1. The planting mechanism 3 can form a tree layer, a shrub layer, and a herb layer on the land in the restoration area. The sowing mechanism 2 is conventional in the art and will not be described in detail here.

[0041] The aquatic organism release unit 4 is to release aquatic organisms into the water area of the restoration area, and realize the comprehensive restoration of the ecosystem of the restoration area through the cooperation between aquatic organisms and trees, shrubs and grasses on land (for example, aquatic organisms (such as fish and benthic animals) provide food for birds and amphibians on land, and insects and plants on land provide food sources for aquatic organisms).

[0042] Implantation institution 3 includes:

[0043] A lifting device 31 (e.g., a lifting bracket, elevator, etc.) has a movable end connected to a carrier 32. A drill rod 34 is mounted on the carrier 32. The outer wall of the drill rod 34 is provided with a spiral blade 36. A water suction port is provided at the lower end of the drill rod 34. A negative pressure pipe 313 is disposed within the drill rod 34. One end of the negative pressure pipe 313 passes through the top of the drill rod 34 and is connected to a negative pressure drainage unit. The negative pressure drainage unit is disposed on a box 37, and the box 37 is disposed on the carrier 32.

[0044] A rotating device 38 (e.g., a motor) is mounted on the housing 37, with its output end connected to the negative pressure drainage unit and also connected to the drill rod 34 via a gear set 39 (two sets of meshing gears).

[0045] Considering that the restoration area is a wetland area, after the drilling rod 34 drives the spiral blade 36 to dig the planting pit, due to the high moisture content in the wet soil, the moisture will seep into the dug planting pit, causing water accumulation in the foundation pit, which can easily lead to the rot of the roots of the seedlings after planting, affecting the growth of the seedlings. For this reason, the negative pressure drainage part of the present application extracts the accumulated water in the planting pit through the water suction port and the negative pressure pipe 313 when the rotating device 38 drives the drilling rod 34 to rotate and dig the planting pit.

[0046] The above-mentioned herbaceous seeds, tree seedlings or shrub seedlings are salt-tolerant plants, such as trees: Tamarix, Fraxinus chinensis, Elaeagnus angustifolia, Robinia pseudoacacia, Populus euphratica, etc., shrubs: Lycium barbarum, Amorpha fruticosa, Hippophae rhamnoides, Artemisia halogenum, etc.; herbaceous plants: Suaeda salsa, Salicornia herba, Phragmites australis, Swertia reed, etc.

[0047] Preferably, the negative pressure drainage unit of this embodiment includes:

[0048] The water pump 316 is hollow at one end and closed at the other end. A matching piston is provided inside the pump. One end of the pump is provided with a one-way water pump pipe connected to the negative pressure pipe 313 and a one-way water outlet pipe connected to the water collection tank 318. Both the one-way water pump pipe and the one-way water outlet pipe are pipes with one-way valves inside.

[0049] Rack 2 317 has one end connected to the pumping cylinder 316 and the other end extending outside the pumping cylinder 316. Rack 2 317 meshes with a toothless gear located at the output end of rotating device 1 38. Rack 2 317 is also connected to the pumping cylinder 316 via an elastic reset member (e.g., a spring) to drive rack 2 317 to reset the piston when the toothless gear and rack 2 317 are separated.

[0050] When the rotating device 1 38 rotates, it not only drives the drill rod 34 to work, but also drives the rack 2 317 through the toothless gear. The rack 2 317 drives the piston to move in the water pumping cylinder 316, and then negative pressure is generated at the negative pressure tube 313 and the water suction port, so that the water in the planting pit is drawn into the water pumping cylinder 316. When the toothless gear and the rack 2 317 are separated, the elastic reset part drives the rack 2 317 to reset, and then the piston resets to compress the water in the water pumping cylinder 316 into the water collecting tank 318. The water in the water collecting tank 318 can be treated regularly.

[0051] A multi-level habitat restoration method for coordinated tree, shrub, grass, terrestrial and aquatic habitats, utilizing the above-mentioned restoration device, comprises the following steps:

[0052] S1: During use, the mobile vehicle 1 is moved to the area to be repaired, and herb seeds are sown at the desired location on the land in the area to be repaired via the sowing mechanism 2. The drill rod 34 is driven downward by the lifting device 31, and the rotating device 38 is turned on to drive the drill rod 34 to rotate to dig a planting hole in the soil. Then, a tree seedling or shrub seedling is placed in the planting hole, and the planting hole is covered with soil. The negative pressure drainage unit pumps out the accumulated water in the planting hole through the water suction port and the negative pressure pipe 313 when the rotating device 38 drives the drill rod 34 to rotate and dig the planting hole.

[0053] S2: placing the aquatic organism delivery unit 4 in the water area to be repaired, and repairing the water area through the aquatic organism delivery unit 4.

[0056] The winch device 41 is provided on the mobile body 1 and is connected to the surface mobile device 42 via a pull rope. The winch device 41 includes a frame, a rotating shaft provided in the frame, and a motor for driving the rotating shaft. The surface mobile device 42 includes, for example, a floating board and a propeller mechanism provided at the bottom of the floating board, but is not limited to this type.

[0057] The chassis 44 is provided on the mobile device 42 on the water surface, and a storage shell 45 is rotatably provided on its top. The top of the storage shell 45 is hollow and is detachably sealed with a shell cover. Several groups of storage chambers (not shown in the figure) are provided in a circular array in the storage shell 45 for storing benthic animals and fish respectively. Taking into account economic benefits, an extensive breeding mode is adopted, with appropriate stocking, but no feeding or medication. The fish are mainly small herbivorous fish, with a small amount of filter-feeding fish to regulate the water environment. Benthic animals are a food source for birds and fish. Large benthic organisms such as snails and shrimps that feed on plants are selected as important members of the restoration area ecosystem, and the bottoms of the several groups of storage chambers are provided with an active opening 1 that runs through the bottom of the storage shell 45.

[0058] A discharge pipe 43 has one end that passes through the surface mobile device 42 and the chassis 44 and is in correspondence with and communicates with one of the movable ports. A valve body is provided in the discharge pipe 43, which may be a solenoid valve. By opening the valve body, benthic animals or fish in the corresponding storage chamber can be discharged from the discharge pipe 43 into the water area.

[0059] The second rotating device 46 is provided on the surface mobile device 42 and is used to drive the storage shell 45 to rotate relative to the chassis 44. The second rotating device 46 includes a servo motor, a gear provided at the output end of the servo motor, and a gear ring meshing with the gear and sleeved on the outer wall of the storage shell 45.

[0060] The electrical appliances in the aquatic organism delivery unit 4 and the land restoration unit of the device can be connected to the external controller via wireless communication.

[0061] Preferably, the bottom of the surface mobile device 42 of this embodiment is provided with a card slot, and the frame of the winch device 41 is provided with a card block adapted to the card slot. When not in use, the surface mobile device 42 can be placed on the mobile body 1 through the cooperation of the card slot and the card block.

[0062] Example 3

[0063] Please see the attached Figure 2 -Attached Figure 3 The outer side of the intercepting net 310 is attached with a brush member 311. The brush member 311 includes a brush, a shaft portion connected to the brush, and a gear provided on the shaft portion. The shaft portion of the brush member 311 passes through the intercepting net 310 and is meshed with a rack 35. The brush member 311 is meshed with a rack 35 through the gear on its shaft portion. The rack 35 is fixedly sleeved on the outer wall of the negative pressure pipe 313. The top end of the negative pressure pipe 313 is rotatably connected to the input end of the negative pressure drainage part through a telescopic pipe through a bearing, which does not affect the rotation of the negative pressure pipe 313 with the drill rod 34 and does not affect its up and down movement. The outer wall fixing sleeve is provided with a driven ring 314, the top of the driven ring 314 is provided with an arc-shaped protrusion 315, and a fixed ring coaxial with the driven ring 314 is provided on the inner wall of the box body 37 and above the driven ring 314. The fixed ring is provided with a contact rod for slidingly abutting against the driven ring 314, and a ball is embedded in the end of the contact rod. When the contact rod contacts the arc-shaped protrusion 315, the negative pressure tube 313 drives the rack 1 35 to move downward, so that the brush part 311 rotates to clean the filter screen. The inner walls of the negative pressure tube 313 and the drill rod 34 are provided with an elastic reset member (such as a spring) for driving the negative pressure tube 313 to drive the rack 1 35 to reset when the contact rod and the arc-shaped protrusion 315 are staggered.

[0064] When the drill rod 34 rotates, the negative pressure tube 313 is also driven to rotate. When the negative pressure tube 313 rotates, it drives the driven ring 314 to rotate relative to the fixed ring. Then, through the cooperation of the contact rod and the arc-shaped protrusion 315, the negative pressure tube 313 drives the rack 35 to move up and down, and then drives the brush part 311 to rotate to clean the filter screen to prevent the filter screen from being blocked and affecting the entry of accumulated water.

[0065] Example 4

[0066] Please see the attached Figure 2 and attached Figure 4 On the basis of Example 1, an insert tube 33 is provided on the outer side of the spiral blade 36 of this embodiment. The insert tube 33 is connected to the supporting frame 32. A soil discharge pipe is provided on one side of the insert tube 33. The soil discharge pipe is connected to the soil processing part, and the soil processing part is connected to the supporting frame 32.

[0067] When the drill rod 34 rotates, the soil is lifted upward by the spiral blades 36. The soil lifted upward is guided and restricted by the insertion tube 33 so that the soil enters the soil processing part from the soil discharge pipe for processing.

[0068] Preferably, the soil processing unit of this embodiment includes:

[0069] The processing shell 319 has an inclined inner cavity with a screen 320, and a vibration device 321 (such as a vibrator) is installed on the screen 320. The higher end of the screen 320 corresponds to the discharge end of the soil discharge pipe, and the lower end corresponds to the impurity discharge pipe 312. The impurity discharge pipe 312 is inserted into the outer wall of the processing shell 319. After entering the processing shell 319 from the soil discharge pipe, the soil falls on the higher end of the screen 320. The vibration device 321 drives the screen 320 to vibrate, and large particles in the soil (such as stones, etc.) roll to the lower end of the screen 320. They can then be discharged by opening the impurity discharge pipe 312, and the soil passes downward through the screen 320.

[0070] The discharge port of the processing shell 319 is provided with a soil discharge pipe, one end of which is connected to the mobile body 1 through an adjustable bracket. After the seedlings are placed in the planting pit, the soil in the processing shell 319 is discharged into the planting pit through the soil discharge pipe to achieve backfilling. A valve body can be set in the soil discharge pipe, and an auxiliary soil suction equipment can also be set to assist in discharging the soil in the processing shell 319, which will not be described in detail here.

[0071] Preferably, a storage tank 322 for storing an improver is provided on the top of the processing shell 319 of this embodiment. The improver can be in liquid or powder form, such as limestone, humic acid or gypsum, etc., and is used to regulate the salt content in the soil. Because the restoration area is a wetland area, the soil in this area is saline-alkali land. By improving the backfilled soil, the salinity of the soil can be significantly reduced, the soil structure can be improved, the air permeability and water retention of the soil can be increased, and the nutrients required for plant growth can be provided, thereby promoting root development and healthy plant growth. Moreover, when the improved soil is backfilled to cover the planting pit, it can provide a more suitable growth environment for the plant roots, reduce salt stress and water evaporation, and thus improve the survival rate and growth rate of the plants.

[0072] A solenoid valve is provided at the discharge end of the storage tank 322 to facilitate control of the discharge opening and closing of the storage tank 322 .

[0073] Preferably, a sealing block 323 is provided at the discharge end of the storage tank 322 of this embodiment and is located below the solenoid valve. A connecting block 324 is rotatably provided at the bottom of the sealing block 323. Both the sealing block 323 and the connecting block 324 can be cylindrical. The connecting block 324 is connected to a discharge pipe 325. Both the sealing block 323 and the connecting block 324 are eccentrically provided with a through hole communicating with the discharge pipe 325. The discharge pipe 325 is transmission-connected to the output end of the rotating device 38. The two can be transmission-connected by a sprocket transmission group (including a sprocket and a chain). When the rotating device 38 is working, the discharge The material pipe 325 drives the connecting block 324 to rotate relative to the sealing block 323, so that the openings on the two are intermittently corresponding. If the solenoid valve at the discharge end of the storage tank 322 is opened, the improver in the storage tank 322 enters the discharge pipe 325 through the opening. The outer wall of the discharge pipe 325 is connected to the stirring support rod 326 that is in contact with the screen 320, and the outer wall of the stirring support rod 326 is provided with a plurality of groups of discharge holes. After entering the discharge pipe 325, the improver enters the stirring support rod 326 and is mixed with the soil under the action of the centrifugal force caused by the rotation of the stirring support rod 326 driven by the discharge pipe 325.
