Description

Technical Field

[0001] This invention relates to the field of ecological restoration technology and equipment, specifically to an adaptive planting device for submerged plants using nutrient pots as carriers. Background Technology

[0002] Submerged plants are an important component of aquatic ecosystems. They can purify eutrophic waters by competing with phytoplankton for light and nutrients, and provide a favorable growth environment for zooplankton, benthic animals, epiphytic fungi, and bacteria, thus maintaining the diversity of aquatic animals and microorganisms. Therefore, restoring aquatic plant communities dominated by submerged plants is an important measure for managing eutrophic waters and rebuilding aquatic ecosystems.

[0003] Artificial planting is an effective way to restore aquatic plants and has been widely used in actual aquatic ecological restoration. Currently, submerged plants are mainly planted manually, with typical methods including manual planting, bamboo stick propagation, basket planting with soil covering, wrapping / sack planting, and cement culvert planting with soil covering. Artificial planting has several drawbacks: it is inefficient, difficult, time-consuming, and costly. Furthermore, the use of auxiliary weights such as stones, sacks, and cement culverts may have new impacts on the bottom layer.

[0004] To achieve large-scale planting and restoration of aquatic plants, mechanization is an important way to improve the efficiency of manual planting operations and reduce labor costs, especially suitable for high-efficiency and low-cost aquatic vegetation restoration in large-scale water areas. Patent document (CN213662434U) discloses an aquatic plant planter. Workers can hold the planter handle and apply pulling force to move the pull rod and connecting plate upward. The clamping rod unfolds outward due to the pulling force, and the aquatic plants to be planted are placed in the middle of the clamping rod. After releasing the pull rod, the two clamping rods automatically return to clamp the aquatic plants inward. The soil fixing plate moves down to the riverbed mud layer along the direction of the planting rod. The rebound force of the first return spring pulls the planting rod downward to carry out the cutting planting operation. This aquatic plant planter assists in manual cutting propagation and secures the soil around the planted cuttings, preventing them from being washed away by water flow. It solves the problem of existing aquatic plant clamps being difficult to adjust. However, this device still relies primarily on manual cutting, resulting in high labor costs and lower planting efficiency compared to ship-structure devices, making it unsuitable for large-scale, submerged plant cultivation. Patent document (CN213662434U) proposes some simplified aquatic plant planting tools; these portable tools are still mainly manually operated, with low levels of automation and intelligence. Another document (CN113455151B) discloses a small number of suspended aquatic plant planting devices, which directly propagate seedlings through cuttings, making standardized planting difficult.

[0005] Patent document (CN105461076A) discloses a method for cultivating and planting submerged plant turf. This method involves creating composite submerged plant turf and then transferring and implanting it into ecosystems such as rivers and lakes to be restored. Submerged plant seedlings are cultivated in shallow ponds using seeds, winter buds, and broken branches attached to a plant fiber mat. During transplanting, the cultivated seedlings, along with the plant fiber mat, are removed from the pond in blocks, forming turf rolls that are then rolled into cylindrical shapes for easy transport and placement in the affected waters. The turf is then placed sequentially on the bottom of the pond and secured with T-shaped tags. While this document provides a novel approach to submerged plants, the related operations are primarily manual, and no related cultivation or planting machinery is disclosed.

[0006] Patent document (CN214708992U) discloses an aquatic plant planting device. A planting frame is installed inside a partition I, which is nested within a partition II. A float I is located above partition I, driving the planting frame and partition II to move up and down. Aquatic plants are planted on the planting frame, and the partition II and planting frame are controlled to sink together to the bottom of the water, allowing the aquatic plant cuttings to insert into the lakebed sediment. The planting frame is equipped with planting cylinders and a driving device. The two side plates of the planting cylinders form a planting cavity, and the driving device controls the opening and closing of the two side plates. This aquatic plant planting device cannot adjust the planting depth of individual aquatic plants, and cannot ensure that the vegetation is planted to the predetermined depth, especially considering uneven riverbeds and potential impurities in the bottom sediment.

[0007] Patent document (CN113455151B) discloses a submerged plant transplanting device, including: a seedling storage chamber, a seedling conveying assembly, a transplanting assembly, and a control system. An underwater ranging sensor measures the depth of the furrowing teeth from the bottom of the water. A conveyor belt transports seedlings from the seedling storage chamber to the receiving hopper. The seedlings fall through the receiving hopper into the conveying pipe and automatically descend to the furrowing teeth at the end of the connecting pipe. A telescopic cylinder II, through its telescopic movement, causes the furrowing teeth to converge and expand, thus realizing the submerged plant transplanting operation. This device largely mechanizes the entire submerged plant transplanting process, reducing labor costs. However, this device does not consider the potential for uneven soil texture in the riverbed during the planting of submerged plant seedlings, nor does it employ standardized planting units, thus limiting its operational efficiency and seedling survival rate.

[0008] Patent document (CN11531688A) discloses an automated submerged plant planting vessel using laser depth sounding, comprising a main hull, a power system, a control module, depth sounding components, a transmission component, a planting chamber, planting components, and a drainage system. This automated submerged plant planting vessel replaces manual planting, improving planting efficiency, saving costs, and standardizing planting density. The laser depth sounding technology used can precisely control the planting depth according to different underwater topographic conditions, enhancing planting results. However, the retractable seedling-grabbing claw used in this automated planting vessel may damage the submerged plant seedlings during the grasping action, leading to a reduced seedling survival rate.

[0009] In summary, existing methods for planting submerged plants mostly involve directly placing seedlings or manual planting, which results in low survival rates of the planted vegetation. Furthermore, the low level of automation in aquatic planting machinery makes it difficult to standardize and scale up planting.

[0010] This invention proposes a novel approach for the standardized and mechanized cultivation of submerged plants. The planting device of this invention can effectively collect environmental information in real time through pressure and distance sensors, precisely control the planting depth according to different riverbed topographic conditions, and provide timely feedback on planting information. This ensures that the nutrient pot units are planted on the riverbed, thereby improving seedling survival rates. It effectively improves planting efficiency and adaptability. Using the nutrient pot units as the planting carrier effectively solves the problems of seedling tangling and damage caused by transportation, facilitating standardized operations for planting submerged plant seedlings and improving operational efficiency and the survival rate of submerged plants. Summary of the Invention

[0011] The purpose of this invention is to achieve standardized and mechanized cultivation of submerged plants, and to propose an adaptive cultivation device for submerged plants using nutrient pots as carriers.

[0012] To solve the above-mentioned technical problems, the present invention adopts the following technical solution:

[0013] An adaptive planting device for submerged plants using nutrient pots as carriers is characterized by comprising a nutrient pot unit, a conveying system, a planting system, a sensing and control system, and a water surface support system.

[0014] The nutrient pot unit contains a nutrient substrate for covering and fixing the seeds or seedlings of submerged plants.

[0015] The conveying system includes a conveyor chain plate, a baffle, a conveying support, and a power unit for the conveying system. The conveyor chain plate is installed on the conveying support, and a conveying baffle is provided on the surface of the conveyor chain plate. The conveyor chain plate and the baffle move under the drive of the power unit for the conveying system, and transport the cultivation pot unit to the planting system.

[0016] The planting system includes a planting telescopic component, a sleeve, a sleeve support, a pressure rod, a sleeve sliding plate, and a sleeve opening adjustment device. The planting telescopic component includes a drive motor, a drive pulley, a driven pulley, a lead screw, a screw, a lead screw nut, a guide sleeve, a push rod, and a guide frame. The drive motor drives the drive pulley, which in turn drives the driven pulley to rotate via belt transmission. The driven pulley drives the lead screw to rotate. The lead screw nut and guide sleeve are fastened together by screws. The lead screw nut and guide sleeve move linearly up and down under the rotation of the lead screw. The guide sleeve and guide frame have a mechanical fit. A push rod is installed below the guide sleeve. A pressure sensor is connected to the end of the push rod, and a pressure rod is connected below the pressure sensor. The pressure rod applies planting force to the nutrient pot unit under the drive of the push rod, causing it to be planted in the underwater soil. The sleeve is fixedly installed on the sleeve support. The sleeve has a feeding port on its side, and a sleeve sliding plate is provided at the feeding port to facilitate the nutrient pot unit sliding into the sleeve. After sliding into the sleeve, the nutrient pot unit is supported by the sleeve opening adjustment device before the pressure rod moves downward for planting.

[0017] The aforementioned sensing and control system includes a control unit, a pressure sensor, and a distance sensor; the distance sensor is mounted on a sleeve; the pressure sensor and the distance sensor respectively measure the planting pressure of the nutrient pot unit and the distance to the riverbed, and input the information to the control unit; the control unit controls the movement distance and speed of the push rod according to the distance to the riverbed and the planting pressure to ensure that the nutrient pot unit is planted into the riverbed at a depth of 5-20cm.

[0018] The water surface carrying system includes a seedling storage bin, a seat, a water surface platform power unit, and a water surface platform. The water surface platform power unit can drive the water surface platform to move on the water surface. The water surface platform is equipped with a seedling storage bin and a seat. The seedling storage bin stores nutrient pot units.

[0019] Furthermore, the nutrient pot unit is made of biodegradable material;

[0020] Furthermore, the sleeve opening adjustment device is provided with 3-6 sets of support rods arranged along the circumference. The support rods are telescopic and adjustable, and their ends are made of elastic and variable material. The sleeve opening adjustment device can adjust the size of the opening at the end of the sleeve according to the actual planting needs to allow different sizes of nutrient pot units to pass through.

[0021] Compared with existing technologies, the submerged plant planting device of this invention has the following advantages and benefits: Workers place the submerged plant nutrient pots on a conveyor belt on a water surface platform. The nutrient pots are then transferred to a pressurized planting device at the end of the platform. As the conveyor baffle moves, the nutrient pots automatically fall into the clamping sleeve, and the pressure rod presses down to complete the planting. Therefore, mechanized, standardized, and large-scale planting can be achieved.

[0022] During operation, the planting platform uses a telescopic planting device to press down a pressure bar, planting submerged plant nutrient pots onto the riverbed. This pressure bar eliminates the need to clamp the submerged plant seedlings, preventing damage to the roots and stems and thus reducing the survival rate. It solves the problems of existing aquatic plant clamps being difficult to adjust and operate, hindering user experience, and also avoids the difficulty of securing aquatic plants to the riverbed when directly placed in the water. Therefore, replacing individual submerged plant seedlings with nutrient pot units effectively improves plant survival rates. The device uses a distance sensor to collect riverbed depth information, allowing for precise control of planting depth based on different riverbed topography to ensure the submerged plant nutrient pots are planted on the riverbed, improving seedling survival rates. A pressure sensor collects planting pressure parameters, which are controlled by a control unit to move the planting telescopic device and provide timely feedback, effectively improving planting density uniformity and efficiency. This planting device significantly reduces manual labor, facilitating efficient and low-cost aquatic vegetation restoration in large-scale water areas. Attached Figure Description

Detailed Implementation

[0030] The technical solutions of the present invention will be clearly and completely described below with reference to the accompanying drawings in the embodiments of the present invention.

[0031] like Figure 1-6 The image shows an embodiment of an adaptive submerged plant planting device using a nutrient pot as a carrier according to the present invention, which mainly includes a nutrient pot unit conveying system, a submerged plant planting system, a control unit, and a water surface mounting system, etc.

[0032] Reference Figure 1-2 In this invention, the nutrient pot unit 18 contains a nutrient substrate for covering and fixing the seeds or seedlings of the submerged plant 3; the conveying system includes a conveyor chain plate 1, a baffle 2, a conveying support 11, and a conveying system power unit 12; the conveyor chain plate 1 is installed on the conveying support 11, and the conveyor chain plate support 11 is connected and fixed in the water surface platform 16; the surface of the conveyor chain plate 1 is provided with a conveying baffle 2; the conveyor chain plate 1 and the baffle 2 move under the drive of the conveying system power unit 12, and transport the nutrient pot unit 18 to the planting system;

[0033] Reference Figure 3-6In this invention, the planting system includes a planting telescopic assembly, a sleeve 8, a sleeve support 6, a pressure rod 5, a sleeve slide plate 7, and a sleeve opening adjustment device 10. The planting telescopic device of the submerged plant planting system can be an electric cylinder, a pneumatic cylinder, or a hydraulic cylinder, which can be selected according to actual working needs. It enables the output shaft push rod 26 of the planting telescopic device to drive the pressure rod 5 to perform a feeding motion in the direction perpendicular to the water surface, and can repeatedly perform the cutting planting action of the nutrient pot unit 18. Taking an electric cylinder as an example, the planting telescopic assembly includes a drive motor 19, an active pulley 20, a passive pulley 21, a lead screw 22, a screw 23, a lead screw nut 24, a guide sleeve 25, a push rod 26, and a guide frame 27. The drive motor 19 drives the active pulley 20, which drives the passive pulley 21 to rotate via belt transmission. 1. Drive screw 22 to rotate. Screw nut 24 and guide sleeve 25 installed on screw 22 are fastened by screw 23. Screw nut 24 and guide sleeve 25 move up and down linearly under the rotation of screw 22. Guide sleeve 25 and guide frame 27 have a mechanical cooperation relationship. Push rod 26 is installed below guide sleeve 25. Pressure sensor 4 is connected to the end of push rod 26. Pressure rod 5 is connected below pressure sensor 4. Pressure rod 5 applies planting force to nutrient pot unit 18 under the drive of push rod 26, so that it is planted in underwater soil. Sleeve 8 is fixedly installed on sleeve bracket 6. Sleeve 8 has a feeding port on the side. Sleeve slide plate 7 is provided at the feeding port to facilitate the nutrient pot unit 18 to slide into sleeve 8. After sliding into sleeve 8, nutrient pot unit 18 is supported by sleeve opening adjustment device 10 before pressure rod 5 moves down to plant.

[0034] The sensor control system includes a control unit 17, a pressure sensor 4, and a distance sensor 9. The distance sensor 9 is mounted on the sleeve 8. The pressure sensor 4 and the distance sensor 9 measure the planting pressure and riverbed distance of the nutrient pot unit 18, respectively, and input the information to the control unit 17. The control unit 17 uses a PLC control module to receive and process the detection signal data, and controls the movement distance and speed of the push rod 26 according to the riverbed distance and planting pressure to ensure that the nutrient pot unit 18 is planted into the riverbed at a depth of 3-20cm.

[0035] The water surface carrying system includes a seedling storage chamber 13, a seat 14, a water surface platform power unit 15, and a water surface platform 16. The water surface platform power unit 15 can drive the water surface platform 16 to move on the water surface. The water surface platform 16 is equipped with a seedling storage chamber 13 and a seat 14. The seedling storage chamber 13 stores nutrient pot units 18.

[0036] The working principle of this invention is as follows:

[0037] The water surface platform power unit 15 drives the water surface platform 16 to run in the water. Driven by the conveyor system power unit 12, the conveyor chain 1 uniformly transports the nutrient pot unit 18 to the seedling outlet at the end of the water surface platform 16. As the conveyor baffle 2 moves, the nutrient pot unit 18 automatically falls into the sleeve 8. The sleeve 8 has an opening adjustment device 10 at its end to adjust the size for holding the nutrient pot unit 18. The planting telescopic mechanism, pressure sensor 4, and distance sensor 9 are all electrically connected to the control unit 17. The distance sensor 9 collects information about the riverbed depth in the planting environment and feeds the water depth data back to the control unit 17 in real time. The control unit 17 integrates and consolidates the data. The information control of the planting telescopic device drives the pressure rod 5 to press down the nutrient pot unit 18, precisely controlling the planting depth according to different riverbed terrain conditions, ensuring that the nutrient pot unit 18 is planted on the riverbed to improve the survival rate of submerged plant seedlings. During the pressing planting process, the pressure sensor 4 collects the pressure data of the output shaft push rod 26 of the planting telescopic device in real time, and promptly feeds the information back to the control unit 17 to facilitate the movement of the planting telescopic device. This avoids the situation where the local soil of the riverbed may be uneven in hardness or contain other impurities, which may prevent the predetermined planting depth from being reached, making it difficult for the roots of submerged plants to penetrate into the bottom of the lake, thus reducing the survival rate and affecting the uniformity of the planting density of submerged plants.

[0038] Example 1

[0039] In this invention, the sleeve 8 is cylindrical, with its upper end attached to the end of the planting telescopic device. A large opening on the side facilitates the insertion of the nutrient pot unit 18. The lower end is equipped with a sleeve opening adjustment device 10. The sleeve opening adjustment device 10 has 3-6 sets of support rods arranged circumferentially. These support rods can be threaded, and springs and wedges are installed at their ends. Bolts and wedges are connected by springs. The inclined surfaces of the three wedges combine to form a constricted shape, which can hold the nutrient pot unit 18 that falls from above the side opening of the sleeve 8. The extension length of the bolts can be adjusted. The adjustable wedge block combination has a closing size to accommodate different sizes of nutrient pot units 18. During the pressure application of the pressure rod 5 for planting and during the retraction process after planting, the deformation of the spring device can prevent interference. The sleeve slide plate 7 is flared, with the larger opening facing upwards, and is fixed at the side opening of the sleeve 8 to prevent the nutrient pot unit 18 from sliding out of the sleeve 8 when it falls from the seedling outlet of the conveyor chain plate 1. The entire submerged plant planting system is vertically fixed at the seedling outlet at the end of the water surface platform 16 by the sleeve bracket 6, with the side opening of the sleeve 8 installed directly opposite the seedling outlet.

[0040] Example 2

[0041] This invention primarily focuses on planting in the nutrient pot unit 18. On one hand, it eliminates the need for pre-planting preparations such as soil preparation, wrapping, and potting, saving planting time and labor costs. On the other hand, compared to planting single submerged plant seedlings, it significantly improves the survival rate of the plants. The number of submerged plants planted per clump is controlled to around 15. The nutrient pot unit 18 is made of materials such as paper and peat moss, containing easily biodegradable plant fibers rich in nitrogen, phosphorus, and potassium. It includes both round and square shapes, with the upper diameter slightly larger than the lower diameter. 8. The bottom has a round hole to help with drainage during the seedling stage and to prevent root rot and root development of submerged plant seedlings after planting. It can be transplanted with the pot on without damaging the seedlings. After the cup decomposes, it will blend with the soil to synthesize organic fertilizer and increase soil organic matter. Appropriate nutrient soil can be prepared in the nutrient pot unit 18 according to the planting needs to promote the initial planting and growth of submerged plants. Appropriate weight can be added to the nutrient pot unit 18 to help it sink to the bottom. In order to ensure the survival rate of seedlings, it is necessary to plant them as soon as they arrive to ensure that the submerged plant seedlings do not dehydrate.

[0042] Example 3

[0043] In this invention, the conveyor chain plate 1 can be driven by belt pulleys, sprockets, etc. According to the size of the nutrient pot unit 18, a conveyor baffle 2 is installed above the conveyor chain plate 1 at appropriate intervals to prevent the nutrient pot unit 18 from moving and colliding during the movement of the water surface platform 16, and to prevent the submerged plant seedlings at the seedling outlet from accumulating and blocking.

[0044] The above description is merely an exemplary embodiment of the present invention. It should be noted that those skilled in the art can make various improvements and modifications without departing from the principles of the present invention, and these improvements and modifications should also be considered within the scope of protection of the present invention.
