Description

Technical Field

[0001] This invention belongs to the field of water ecological governance technology, specifically relating to a device for the refined resource utilization of aquatic higher plants. Background Technology

[0002] Aquatic higher plants are a group within the ecological framework and an important component of aquatic ecosystems. Based on their growth and lifestyle in water, they are generally divided into floating-leaved plants and submerged plants. Floating-leaved plants have leaves that float on the water surface, while submerged plants are completely submerged. Appropriate amounts of aquatic higher plants can eliminate pollution, purify water, and restore aquatic ecosystems. However, aquatic plants have extensive root systems, strong germination capabilities, rapid growth, and fast reproduction. Excessive or withered aquatic higher plants, if not properly removed in a timely manner, can not only affect navigation but also deplete oxygen in the water, causing secondary water pollution and accelerating eutrophication.

[0003] Currently, the main method for managing aquatic higher plants is to organize manpower for harvesting. This is labor-intensive, inefficient, and the harvested aquatic higher plants are not reused, resulting in a waste of resources. Summary of the Invention

Detailed Implementation

[0038] The technical solution of the present invention will now be described in detail with reference to the accompanying drawings.

[0039] This invention provides a device for the refined resource utilization of aquatic higher plants, such as... Figure 1 and Figure 2 As shown, the system includes a hull 1 and, mounted on the hull 1, a salvage device 2, a pretreatment device, a sorting device, a crushing device 4, a first loading device 5, a drying device 6, and a second loading device 7. The salvage device 2, installed at the front of the hull 1, is used to salvage aquatic higher plants from the river channel and transport them to the sorting device. The pretreatment device is used to screen the aquatic higher plants by species, obtaining floating-leaved plants and submerged plants, and then transporting the floating-leaved and submerged plants to the sorting device, respectively. The sorting device is used to screen the floating-leaved and submerged plants by maturity, obtaining floating-leaved and submerged plants, and then transporting the floating-leaved and submerged plants to the sorting device, respectively. The crushing device 4 is used to crush mature plants and transport them to the first loading device 5. The first loading device 5 is used to collect the crushed mature plants. The drying device 6 is used to dry immature plants and transport them to the second loading device 7. The second loading device 7 is used to collect the dried immature plants.

[0040] The aquatic higher plant fine resource utilization equipment of the above embodiment includes a salvage device 2, a sorting device, a crushing device 4, a first loading device 5, a drying device 6, and a second loading device 7 installed on the hull 1. The salvage device 2 salvages aquatic higher plants from the river and transports them to the pretreatment device. The pretreatment device screens the aquatic higher plants to obtain floating-leaved plants and submerged plants, and then transports the floating-leaved plants and submerged plants to the sorting device. The sorting device screens the floating-leaved plants and submerged plants according to their maturity to obtain mature plants and immature plants. The mature plants are transported to the crushing device, and the immature plants are transported to the drying device. The crushing device crushes the mature plants, which are then collected by the first loading device. The drying device dries the immature plants, which are then collected by the second loading device. The aquatic higher plant fine resource utilization equipment provided by this invention integrates the salvage, sorting, and processing of aquatic higher plants. It has a high degree of automation, reduces manual labor intensity, improves the cleaning efficiency of aquatic higher plants, and enables the secondary utilization of aquatic plant resources after processing. The aquatic higher plant fine resource utilization equipment provided by this invention first screens the floating-leaved plants and submerged plants among the salvaged aquatic higher plants. The floating-leaved plants, with their abundant leaves, can be processed and used to feed animals that prefer leafy greens, while the submerged plants, with their abundant roots and stems, can be processed and used to feed animals that prefer root and stem feed. The screened floating-leaved and submerged plants are then further screened according to maturity. Mature plants are crushed into loose material and collected for use as feed for adult animals, while immature plants are dried and collected for use as feed for young animals. Finally, mature floating-leaved plant material, immature floating-leaved plant material, mature submerged plant material, and immature submerged plant material are obtained, thus achieving fine classification and utilization of aquatic plants.

[0041] As a preferred option, such as Figure 1 and Figure 3 As shown, the salvage device 2 in this embodiment includes a material-feeding assembly 22, a first conveying assembly 23, and a cutting assembly 21 arranged sequentially from top to bottom. The cutting assembly 21, material-feeding assembly 22, and first conveying assembly 23 are all connected to the hull 1. During operation, the cutting assembly 21 cuts the roots and stems of the aquatic higher plants at the bottom of the pool. The material-feeding assembly 22 moves the aquatic higher plants, causing them to fall to the feed end of the first conveying assembly 23. The first conveying assembly 23 then conveys the plants to the pre-treatment device.

[0042] Specifically, the cutting assembly 21 includes a strip cutter 211 and a support rod. The strip cutter 211 is arranged along the width of the hull and is installed on the outer side of the front of the hull via the support rod. The bottom of the strip cutter 211 is horizontal, cutting the roots and stems of plants against the silt layer at the bottom of the riverbed. This ensures that the plants are cut while also compacting the silt layer, preventing damage to the original silt layer structure at the bottom of the riverbed. The top of the strip cutter 211 has an inclined guide surface, which guides the plants after they are cut by the material feeding assembly, ensuring that the plants fall more easily onto the first conveying assembly.

[0043] The feeding assembly 22 includes a lever and feeding wheels 221. The lever is inclined downwards, and multiple feeding wheels are spaced apart from top to bottom on the lever. Each feeding wheel 221 is rotatably connected to the lever, and the lever is correspondingly provided with multiple first driving members, which are connected one-to-one with the feeding wheels 221 to drive the feeding wheels to rotate. One side of the feeding wheel 221 is provided with multiple feeding posts 222, which are spaced apart circumferentially along the feeding wheel 221. During operation, the uppermost feeding wheel is located above the liquid surface, and the lowermost feeding wheel is located at the feeding end of the first conveying assembly 23. All the feeding wheels 221 rotate. The feeding wheels above the liquid surface push the floating plants downwards, and then the feeding wheels below push them sequentially to the feeding end of the first conveying component. At the same time, the feeding wheels push the submerged plants to the feeding end of the first conveying component, preventing the plants from scattering into the river channel under the impact of the water. This also ensures that the plants are distributed along the Y-axis into the first conveying component, that is, arranged along the length of the ship and along the direction of plant transportation, which facilitates subsequent processing.

[0044] The first conveying assembly 23 includes an upper conveying assembly 231 and a lower conveying assembly 232 arranged in parallel, with the upper conveying assembly positioned above the lower conveying assembly. One end of each of the upper and lower conveying assemblies is located within the hull, with the ends furthest from the hull forming the front end, which constitutes the feed inlet of the first conveying assembly. The distance between the front end of the upper conveying assembly and the front end of the hull is less than the distance between the front end of the lower conveying assembly and the front end of the hull; that is, in the plant conveying direction, the front end of the upper conveying assembly lags behind the front end of the lower conveying assembly. Thus, the area between the front ends of the lower and upper conveying assemblies forms the feed inlet. Both the upper and lower conveying assemblies employ belt conveyor structures, and each belt is equipped with pressure posts 233. The pressure posts 233 of the upper and lower conveying assemblies are staggered, pressing down on the plants during conveying to prevent them from scattering into the riverbed due to water impact. The front sections of the upper conveying assembly 231 and the lower conveying assembly 232 are horizontally positioned.

[0045] During operation, the hull 1 moves forward within the river channel, and the strip cutter 211 of the cutting assembly 21 follows the hull 1 forward, cutting the roots and stems of aquatic higher plants. All feeding wheels 221 rotate, and feeding columns 222 push the plants towards the first conveying assembly, causing the plants to fall into the inlet. The upper and lower conveying assemblies squeeze the plants and convey them backward into the hull.

[0046] Preferably, the cutter assembly 21, the feeding assembly 22, and the first conveying assembly 23 are all rotatably mounted on the hull. Specifically, the support rod of the cutter assembly 21 is rotatably mounted on the outer side of the front end of the hull, the feeding lever of the feeding assembly 22 is rotatably mounted on the outer side of the front end of the hull, and one end of the upper and lower conveying assemblies is rotatably mounted inside the hull. In this way, the cutter assembly 21, the feeding assembly 22, and the first conveying assembly 23 can all be adjusted up and down according to the depth of different working channels, so that the cutter assembly 21 is located at the bottom of the pool, and the feeding wheel of the uppermost feeding assembly is located above the liquid surface, thereby successfully harvesting both floating-leaved plants and submerged plants.

[0047] like Figure 4 As shown, the pretreatment device includes a box 311 with a top opening and a second conveying assembly 312. The box 311 is filled with water and has a first vibrator. The inlet end of the second conveying assembly 312 is located at the bottom of the box 311, and the outlet end extends out of the box from the top opening and connects to the sorting device. A first filter plate 313 is provided inside the box 311, with one end of the first filter plate 313 rotatably connected to the side wall of the box. In the initial state, the first filter plate 313 is vertical, with its free end below the liquid surface and the end connected to the box 311 above the liquid surface. The first filter plate 313 divides the inside of the box 311 into a screening area and a conveying area, as shown. Figure 4The left side of the first filter plate is the screening section, and the right side is the conveying section. The feed end of the second conveying component 312 is located at the bottom of the screening section, and the part of the second conveying component 312 located in the conveying section is arranged at an upward angle. The first filter plate 313 can be rotated at an angle of not less than 180°. During operation, the first filter plate 313 rotates from a vertical position toward the screening section and upward, and after rotating 180°, it continues to rotate toward the conveying section and downward to the preset position.

[0048] During operation, the retrieval device 2 transports aquatic higher plants into a water-filled container 311. The first vibrator is activated. Because floating-leaved plants have more abundant leaves and smaller stems and leaves, and their leaves are mostly flat with many pores on the epidermis, resulting in lower density, they move towards the liquid surface and eventually float. Submerged plants, with smaller leaves and more developed roots and stems, have higher density and move towards the bottom of the container, eventually landing on the second conveying assembly 312 located at the bottom of the screening section. The second conveying assembly 312 transports the submerged plants out of the container until they reach the sorting device. The sorting device screens the submerged plants by maturity, separating mature and immature plants. Mature plants are conveyed to the crushing device and then collected by the first loading device, while immature plants are conveyed to the drying device and then collected by the second loading device. After all the submerged plants at the bottom of the container have undergone maturity screening and subsequent processing and collection, the first filter plate 313 is flipped to the left and upward. During this flipping process, floating leaf plants on the liquid surface are collected. After flipping 180°, the floating leaf plants collected on the first filter plate fall onto the second conveying component located in the conveying area. The second conveying component 312 transports the floating leaf plants out of the container until they reach the sorting device. The sorting device screens the floating leaf plants for maturity, obtaining mature and immature plants. Mature plants are conveyed to the crushing device and then collected by the first loading device, while immature plants are conveyed to the drying device and then collected by the second loading device.

[0049] Preferably, the second conveying component adopts a roller conveying structure. After the box is vibrated, heavier particles such as stones and pebbles will sink onto the second conveying component along with the submerged plants. When conveyed to the conveying area, due to the upward tilt, most particles will fall through the gaps between the rollers and into the bottom of the conveying area, thereby reducing the number of particles entering the sorting device and performing the first filtration of particles. Because the gaps between the rollers are relatively large, and the larger the particle size, the greater its weight, and the easier it is to fall during the upward conveying process, the plants conveyed to the sorting device contain almost no large particles, only a small number of small particles.

[0050] In this embodiment, the pretreatment device utilizes the characteristics of floating-leaved and submerged plants. A water-filled vibrating chamber efficiently screens the plants. The screened submerged and floating-leaved plants are then sequentially conveyed to a classification device for maturity screening via a second conveyor assembly. After pretreatment and classification, mature and immature submerged plants, as well as mature and immature floating-leaved plants, are obtained, achieving refined resource classification and utilization. Since both screened submerged and floating-leaved plants are sequentially conveyed to the classification device via the second conveyor assembly, a single device can be used for maturity screening and subsequent processing of both types of plants, eliminating the need for two classification devices and four subsequent processing devices, thus simplifying the overall equipment structure.

[0051] like Figure 1 , Figure 2 and Figure 5 As shown, the sorting device 32 includes a third conveying component. The inlet end of the third conveying component is connected to the outlet end of the second conveying component, and the conveying directions of the third and second conveying components are the same. The outlet end of the third conveying component is connected to the crushing device 4 and the drying device 6. The third conveying component adopts a belt conveyor structure, and a third filter hole 322 is provided on the third belt 321 of the third conveying component. Multiple air nozzles 323 are spaced along the conveying direction on one side of the third belt, such as... Figure 6 As shown, the air jet direction of the nozzle is perpendicular to the conveying direction. The discharge end of the second conveying component is connected to the side of the third conveying component where the nozzle is located. Figure 6 As shown, a filter plate 324 and a stone collection box 325 are inclinedly arranged below the third conveying assembly, with the bottom end of the second filter plate 324 located in the stone collection box 325. The pore diameter of the second filter plate 324 is smaller than that of the third filter plate. A water collection box 326 is arranged below the second filter plate 324, and the water collection box is connected to the pretreatment device body through a water pipe. A second vibrator 327 is arranged on the second filter plate 324.

[0052] During operation, the pretreatment device conveys the screened plants to the side of the third conveyor belt equipped with air nozzles. Water and a small amount of particulate matter from the plants fall through the third filter holes onto the second filter plate 324, where the third conveyor belt performs a second filtration of the particles. The second vibrator 327 drives the second filter plate 324 to vibrate, intercepting the particles. Water passes through the second filter plate and falls into the water collection tank 326 below. The water in the water collection tank 326 flows into the pretreatment device for plant classification. Particles are intercepted on the surface of the second filter plate and finally fall into the stone collection box 325. Air nozzles 323 spray air onto the plants on the third conveyor belt. Due to the different densities of mature and immature aquatic plants, the airflow blows the less dense mature aquatic plants to the other side of the third conveyor belt, while the denser immature aquatic plants remain on the side with the air nozzles. The third conveyor assembly conveys the mature aquatic plants on one side to the crushing device and the immature aquatic plants on the other side to the drying device.

[0053] The classification device in this embodiment sequentially screens the submerged and floating-leaved plants for maturity, achieving refined resource classification and utilization. Utilizing the characteristics of mature and immature plants, an air jet method is employed for maturity screening, improving the accuracy of screening and reducing the number of immature plants among the final mature plants and vice versa. The screened mature and immature plants are located on the same conveyor belt and can be directly and simultaneously transported to the crushing and drying devices, resulting in a simple structure and high conveying efficiency. Water filtered from the plants is recycled back to the pretreatment device for further classification, conserving water resources.

[0054] As a preferred option, such as Figure 2 , Figure 5 and Figure 6 As shown, the crushing device 4 includes a fourth conveying assembly, a pressing assembly 43, a crushing plate 44, a first cutting assembly 45, and a second cutting assembly 46. The feed end of the fourth conveying assembly is connected to the discharge end of the third conveying assembly (without the air nozzle), and the fourth and third conveying assemblies have the same conveying direction. The fourth conveying assembly adopts a belt conveyor structure, and the fourth belt 41 of the fourth conveying assembly is provided with a fourth filter hole 42. The pressing assembly 43 is located above the fourth conveying assembly. One end of the crushing plate 44 is connected to the discharge end of the fourth conveying assembly, and the other end of the crushing plate 44 is connected to the first storage device 5. The first cutting assembly 45 and the second cutting assembly 46 are located above the crushing plate 44, and are used to cut mature plants and convey them towards the first storage device.

[0055] Specifically, the extrusion assembly 43 includes an extrusion roller, and multiple extrusion angles are set at intervals around the circumference of the extrusion roller. For example... Figure 8As shown, the first cutting assembly 45 includes a rotating shaft and multiple cutting plates 451. The multiple cutting plates 451 are respectively mounted around the rotating shaft via support plates 452. Each cutting plate has a blade 453 on one side. The rotating shaft rotates at the same speed as the extrusion wheel, and the extrusion distance between two adjacent extrusion angles is the same as the distance between the blades of two adjacent cutting plates. Therefore, when the first cutting assembly cuts the plant into strips, the cut and extrusion marks coincide, making it easier to cut the plant. The second cutting assembly 46 includes a crushing wheel with multiple blades around its circumference.

[0056] During operation, mature plants are conveyed onto the fourth conveyor belt 41. First, an extrusion assembly creates indentations on the plants, facilitating the subsequent cutting of the plants into strips by the first cutting assembly. Furthermore, the extrusion assembly squeezes out a small amount of water from the mature plants, further enhancing the dehydration and drying effect. The extruded mature plants are then conveyed to the crushing plate 44, where the first cutting assembly cuts them into strips along the indentations. Finally, the second cutting assembly further crushes the strips of plants.

[0057] The crushing device in this embodiment first squeezes out indentations on the plant, then cuts the plant into strips along the indentations, further cutting the plant and aquatic plants, and finally further crushes the strips of plant.

[0058] As a preferred option, such as Figure 2 As shown, the first warehousing device 5 in this embodiment includes a hopper 51, a discharge plate 52, and a first collection box 53. As... Figure 9 As shown, the top of the end of the hopper 51 connected to the crushing device 4 has a bulk material inlet 54, and the bottom of the other end has a bulk material outlet 55. A fifth conveying assembly 58 is installed inside the hopper, employing a spiral conveying structure. During the conveying process of the spiral conveyor structure, the crushed plant material increases its travel length within the hopper 51, which aids in drying. Furthermore, the crushed aquatic plants are scattered within the hopper 51, increasing the contact area with the air inside, further contributing to drying. A heating jacket 56 is fitted over the outer wall of the hopper, raising the temperature of the side walls. Under the spiral conveying structure, the crushed plant material, under the influence of centrifugal force, is conveyed forward along the inner wall of the hopper 51. Therefore, the external heating jacket 56 further enhances the drying effect of the bulk material. Figure 10As shown, the discharge plate 52 is inclined downwards, with its top end located below the bulk material outlet 55 and its bottom end located inside the first collection box 53. Preferably, the discharge plate 52 is provided with guide strips 57, which have a horizontal portion and an inclined portion. The horizontal portion is parallel to the bottom plate of the hull 1, and the inclined portion is located above the horizontal portion. When the dried plant material is discharged from the hopper, it falls on the inclined portion of the uppermost guide strip and then falls downwards into the first collection box. By setting the guide strips, the sliding path of the bulk material and the contact area with air can be increased, which helps to dry the bulk material again.

[0059] During operation, the plant material, after being crushed by the crushing device 4, enters the hopper 51 through the bulk material inlet 54. The fifth conveying component 58 transports the bulk material to the bulk material outlet 55. During the conveying process, the bulk material is dried. The bulk material falls from the bulk material outlet 55 onto the drop plate 52 and then into the first collection box 53.

[0060] In this embodiment, the first feeding device dries the bulk material within the silo 51 by extending the conveying path, increasing the contact area with air, and conveying it forward along the heated inner wall of the silo 51. The material then falls through a drop plate to the first collection box 53 for further drying.

[0061] As a preferred option, such as Figure 1 As shown, the drying device 6 in this embodiment includes a drying plate 61, a hot air blower 62, a circulating fan 63, and a stirring assembly. The drying plate 61 is fixed to the hull 1 by a vibrator 66. Figure 5 and Figure 6 As shown, one end of the drying plate 61 is connected to the side of the air nozzle mounted on the discharge end of the third conveying assembly, and the other end is connected to the second inlet device 7. The drying plate 61 is provided with ventilation holes 611. Preferably, multiple partitions 65 are spaced apart on the upper surface of the drying plate 61, the partitions 65 are inclined, and the angle between the partitions 65 and the drying plate 61 is an acute angle. When immature plants are conveyed onto the drying plate 61, the plants will rest on two adjacent partitions 65, and the ventilation holes 611 can transfer hot air between the two adjacent partitions 65 to dry the immature plants. The air outlet 621 of the hot air blower 62 is located below the drying plate 61 and near the end of the drying plate connected to the second inlet device. The air inlet 631 of the circulating fan 63 is located above the drying plate and opposite the air outlet 621 of the hot air blower. The air outlet 632 of the circulating fan is located above the drying plate and near the end where the drying plate connects to the sorting device. The air outlet of the circulating fan directs the airflow towards the end where the drying plate connects to the second inlet device. A guiding assembly is positioned above the drying plate and is used to guide immature plants on the drying plate towards the second inlet device. Specifically, as... Figure 11As shown, the swaying assembly includes a first connecting rod 641, a second connecting rod 642, and a swaying plate 643. One end of the first connecting rod 641 and the second connecting rod 642 are rotatably mounted on the hull 1, and the other ends of the swaying plate 643 are hinged to both ends of the first connecting rod 641 and the second connecting rod 642, respectively. By rotating the first connecting rod 641, the swaying plate 643 is driven to sway the immature plants from left to right on the drying plate 61, ensuring that the plants are distributed in a straight line on the drying plate 61 and moving the plants towards the second loading device. The swaying part 644 is located on the side of the swaying plate 643 closest to the drying plate 61. The swaying part 644 is arc-shaped, which can avoid interference with the partition 65 when swaying the plants.

[0062] During operation, after the immature plants are conveyed onto the drying plate 61, the outlet 632 of the circulating fan blows hot air with a certain amount of moisture from above the drying plate 61 at an angle towards the immature plants, causing them to move towards the second loading device. The outlet 621 of the hot air blows fresh hot air from below the drying plate 61 towards the immature plants. The hot air passes through the ventilation hole 611 and over the immature plants, then is drawn in by the suction port 631 of the circulating fan above the drying plate 61, and then blown towards the immature plants from the outlet 632 of the circulating fan.

[0063] In this embodiment, the drying device uses a circulating fan to pre-dry the immature plants as they enter the drying plate. Then, as the immature plants move towards the second loading chamber, they are further dried using a hot air fan. During hot air drying, the circulating fan absorbs excess hot air for pre-drying. That is, pre-drying is first performed with hot air mixed with moisture, followed by post-drying with pure hot air. This dual drying process improves the drying effect and avoids wasting excess heat from the hot air.

[0064] As a preferred option, such as Figure 1 and Figure 12As shown, the second loading device 7 in this embodiment includes a steering assembly 71, a first unloading assembly 72, a sixth conveying assembly, a second unloading assembly 74, and a second collection box 75 arranged sequentially. A cable tie gun is provided at the end of the sixth conveying assembly connected to the second unloading assembly 74. The steering device 71 is mounted on one side of the drying plate 61 via a bracket and is used to turn the dried immature plants. The steering device 71 uses a conventional 90° turning conveyor belt. When the retrieval device 2 retrieves aquatic higher plants, under the action of the feeding assembly, the plants are distributed along the Y-axis, that is, arranged along the length of the ship and also along the plant conveying direction. The plants are always distributed along the Y-axis as they are conveyed through the primary screening device, secondary screening device, and drying device. By setting the steering device 71, the dried immature plants can be turned horizontally by 90°, that is, the plants in the plane are changed from a Y-axis distribution to an X-axis distribution, facilitating the subsequent conveying by the sixth conveying assembly. Both the first feeding assembly 72 and the second feeding assembly 74 use rectangular cross-section conveying pipes, and both are inclined. After being turned, the immature plants fall onto the sixth conveying assembly via the first feeding assembly 72. When the sixth conveying assembly transports the immature plants to the discharge end, a cable tie gun bundles the immature plants. The bundled immature plants then fall into the second collection box 75 via the second feeding assembly.

[0065] Preferred, such as Figure 12As shown, the sixth conveying assembly includes two progressive plates 731 and a temporary storage plate 732. The two progressive plates are respectively mounted on both sides of the temporary storage plate via two sets of progressive drive assemblies. The progressive drive assemblies are used to drive the progressive plates from the initial position towards the second collection box to the progressive position, and then back towards the first material assembly to the initial position. The top of the progressive plate has multiple progressive slots 7311 along its length, and the top of the temporary storage plate 732 has multiple temporary storage slots 7321 along its length. The progressive drive assembly includes two supports 7331, two drive wheels 7332, a synchronous belt 7333, two eccentric wheels 7334, and a motor. The two eccentric wheels are spaced apart at the bottom of the progressive plate along its length. The two drive wheels are respectively mounted on the two supports 7331, and the motor is connected to one of the drive wheels. The synchronous belt 7333 is sleeved on the two drive wheels, and the two drive wheels are respectively connected to the two eccentric wheels, driving the eccentric wheels to rotate. The eccentric wheel rotates eccentrically, causing the progressive plate to move upwards towards the second collection box, then downwards towards the second collection box, then downwards towards the first feeding assembly, and finally upwards towards the first feeding assembly, completing one rotational motion. This drives the transfer of plants between two adjacent temporary storage tanks 75, thus completing the conveying of immature plants. A baffle 722 is rotatably installed at the discharge port of the first feeding assembly, which closes the discharge port of the first feeding assembly when no external force is applied. One of the progressive plates 731 has a protrusion 7312 at the top of the end that connects to the first feeding assembly 72. When the progressive plate 731 moves upwards towards the second collection box, the protrusion 7312 applies force to the baffle 722, causing the baffle 722 to flip upwards and open the discharge port of the first feeding assembly.

[0066] During operation, dried immature plants are conveyed to a steering device 71, which then turns the plants, causing them to fall into the first feeding assembly. When the progressive drive assembly drives the progressive plate 731 upwards and towards the second collection box, and then downwards and towards the second collection box again, the protrusion 7312 applies force to the baffle 722, causing it to flip upwards and open the outlet of the first feeding assembly. The immature plants fall into the first progressive groove 7311. Subsequent progressive grooves 7311 then lift plants from their corresponding temporary storage slots 7321. When the progressive drive assembly drives the progressive plate 731 downwards and towards the first feeding assembly, the protrusion 7312 disengages from the baffle 722, causing it to flip downwards and close the outlet of the first feeding assembly. Simultaneously, the first progressive groove 7311 places plants into the first temporary storage slot, and subsequent progressive grooves 7311 place plants into the next temporary storage slot after the original temporary storage slot. When the progressive drive assembly drives the progressive plate 731 downward and towards the first feeding assembly, and upward and towards the first feeding assembly, the progressive groove returns to its initial position. Thus, the progressive plate achieves forward feeding after one rotation. The cable tie gun bundles the immature plants conveyed to the last temporary storage slot, and the bundled immature plants fall into the second collection box 75 via the second feeding assembly.

[0067] In this embodiment, the second loading device and the sixth conveying component adopt a progressive structure, which enables the transport of plants in bundles, facilitating their bundling. By setting a turning device 71, the dried immature plants can be turned horizontally by 90°, that is, the plants in the plane are changed from a Y-axis distribution to an X-axis distribution, which facilitates the subsequent progressive transport by the sixth conveying component.

[0068] The workflow of the aquatic higher plant fine resource utilization equipment of the above preferred embodiment is as follows:

[0069] As the vessel enters the river channel, the cutting assembly 21, the feeding assembly 22, and the first conveying assembly 23 are adjusted vertically according to the channel depth, ensuring that the cutting assembly 21 is positioned at the bottom of the pool and the feeding wheel at the top of the feeding assembly is above the liquid surface. The vessel 1 moves forward within the river channel, and the strip-shaped cutter 211 of the cutting assembly 21 follows the vessel 1 forward, cutting the roots and stems of aquatic higher plants. All first driving components drive the corresponding feeding wheels 221 to rotate, pushing floating-leaved and submerged plants towards the first conveying assembly, causing the plants to fall into the inlet. The upper and lower conveying assemblies compress the plants and convey them backward to the pre-treatment device within the vessel hull. After aquatic higher plants are transported into the water-filled container 311, the first vibrator is activated. Floating-leaved plants, with their more abundant leaves and smaller stems and leaves, flattened leaves with numerous stomata on the leaf epidermis, and lower density, move towards the liquid surface and eventually float. Submerged plants, with smaller leaves and more developed root systems, and higher density, move towards the bottom of the container and eventually land on the second conveying assembly 312 located at the bottom of the screening section. The second conveying assembly 312 transports the submerged plants out of the container until they are conveyed to the sorting device. The sorting device screens immature plants for maturity, separating them into mature and immature plants. Mature plants are conveyed to the crushing device and then collected by the first loading device, while immature plants are conveyed to the drying device and then collected by the second loading device. After all the submerged plants at the bottom of the container have undergone maturity screening and subsequent processing and collection, the first filter plate 313 is flipped to the left and upward. During this flipping process, floating plants on the liquid surface are collected. After flipping 180°, the floating plants collected on the first filter plate fall onto the second conveyor assembly located in the conveying area. The second conveyor assembly 312 transports the floating plants out of the container until they are conveyed to the sorting device. The sorting device screens the floating plants for maturity, obtaining mature and immature plants. Mature plants are conveyed to the crushing device and then collected by the first loading device, while immature plants are conveyed to the drying device and then collected by the second loading device. The pretreatment device conveys the screened plants to the side of the third conveyor assembly's third belt equipped with air nozzles. Water and a small amount of particulate matter in the plants fall through the third filter holes onto the second filter plate 324, where the third belt performs a second filtration of the particles. The second vibrator 327 drives the second filter plate 324 to vibrate, intercepting particles. Water passes through the second filter plate and falls into the water collection tank 326 below. The water in the water collection tank 326 is then fed into the pretreatment device for plant species sieving. Particles are intercepted on the surface of the second filter plate and finally fall into the stone collection box 325. The air nozzle 323 sprays air onto the plants on the third belt. Due to the different densities of mature and immature aquatic plants, the airflow blows the less dense mature aquatic plants to the other side of the third belt, while the denser immature aquatic plants remain on the side where the air nozzle is located.The third conveying unit transports mature aquatic plants on one side to the crushing device and immature aquatic plants on the other side to the drying device.

[0070] After mature plants are conveyed onto the fourth conveyor belt 41, they are first pressed by the extrusion assembly to create indentations, facilitating the subsequent cutting by the first cutting assembly. Furthermore, the extrusion assembly squeezes out a small amount of water from the mature plants, further aiding in dehydration and drying. The extruded mature plants are then conveyed to the crushing plate 44, where the first cutting assembly cuts them into strips along the indentations. Finally, the second cutting assembly further crushes the strips. The crushed plant material enters the hopper 51 through the material inlet 54, and the fifth conveyor assembly 58 transports it to the material outlet 55, drying the material during transport. The material falls from the material outlet 55 onto the drop plate 52 and then into the first collection bin 53. Once all the mature material from submerged plants has been processed, the first collection bin 53 is replaced to hold the mature material from floating-leaved plants.

[0071] After the immature plants are conveyed onto the drying plate 61, the outlet 632 of the circulating fan blows hot air with a certain amount of moisture from above the drying plate 61 at an angle towards the immature plants, causing them to move towards the second loading device. The outlet 621 of the hot air blows fresh hot air from below the drying plate 61 towards the immature plants. The hot air passes through the ventilation holes 611 and over the immature plants, then is drawn in by the suction port 631 of the circulating fan above the drying plate 61, and then blown back towards the immature plants from the outlet 632 of the circulating fan. The dried immature plants are then conveyed to the turning device 71, which turns the dried immature plants, causing them to fall into the first feeding assembly. When the progressive drive assembly drives the progressive plate 731 upward and towards the second collection box, and then downward and towards the second collection box, the protrusion 7312 applies force to the baffle 722, causing the baffle 722 to flip upward and open the discharge port of the first feeding assembly. Immature plants fall into the first progressive groove 7311. Subsequent progressive grooves 7311 lift the plants in their corresponding temporary storage slots 7321 and remove them from the temporary storage slots. When the progressive drive assembly drives the progressive plate 731 downward and towards the first feeding assembly, the protrusion 7312 disengages from the baffle 722, and the baffle flips downward and closes the discharge port of the first feeding assembly. Simultaneously, the first progressive groove 7311 places the plants into the first temporary storage slot, and subsequent progressive grooves 7311 place the plants into the next temporary storage slot after the original temporary storage slot. When the progressive drive assembly drives the progressive plate 731 downward and towards the first feeding assembly, and upward and towards the first feeding assembly, the progressive groove returns to its initial position. Thus, the progressive plate achieves forward feeding after one rotation. The cable tie gun bundles the immature plants conveyed to the last temporary storage tank, and the bundled immature plants fall into the second collection box 75 via the second feeding component. After all the immature material of the submerged plants has been processed, the second collection box 75 is replaced to hold the immature material of the floating-leaved plants.

[0072] Ultimately, we can obtain mature materials from submerged plants, immature materials from submerged plants, mature materials from floating-leaved plants, and immature materials from floating-leaved plants. The mature materials from submerged plants are used to feed adult animals that prefer to eat roots and stems, while the immature materials from submerged plants are used to feed young animals that prefer to eat roots and stems. The mature materials from floating-leaved plants are used to feed adult animals that prefer to eat leaves, while the immature materials from floating-leaved plants are used to feed young animals that prefer to eat leaves, thus achieving the refined utilization of aquatic higher plant resources.

[0073] The above description is merely a specific embodiment of the present invention, but the scope of protection of the present invention is not limited thereto. Any variations or substitutions that can be easily conceived by those skilled in the art within the scope of the technology disclosed in the present invention should be included within the scope of protection of the present invention.
