Description

Technical Field

[0001] This utility model relates to the field of agricultural machinery technology, and in particular to a drive device for an amphibious aquatic grass harvesting boat. Background Technology

[0002] With the development of society and economy and the improvement of people's living standards, the degree of agricultural mechanization and electrification is constantly deepening, and the modernization and economic management of river crab farming are also constantly improving. However, at present, since river crabs are mostly raised using the grass-planting farming model, aquatic plants are an indispensable habitat, hiding place, and molting place for river crabs. However, it is easy for aquatic plants to grow too vigorously and cover the entire farming water surface, which can easily lead to insufficient dissolved oxygen in the water and affect the growth of river crabs. Moreover, aquatic plants that extend above the water surface can hinder the generation of waves and prevent oxygen from the air from entering the water. Therefore, aquatic plants need to be pruned.

[0003] In existing technologies, aquatic plants are typically harvested using floating platforms equipped with harvesting devices. However, the launching, retrieval, and transportation of these platforms all require manual intervention, and manual operation is also necessary, making them inconvenient and impacting harvesting efficiency. Therefore, devising a drive mechanism that enables the floating platform to move autonomously and operate in water is a problem that those skilled in the art need to consider. Utility Model Content

[0004] The purpose of this invention is to provide a drive device for an amphibious aquatic weed harvesting vessel to solve the problems of inconvenient floating platform transfer and driving in water in the prior art.

[0005] The technical solution of this utility model is: a drive device for an amphibious aquatic grass harvesting boat. The harvesting boat includes a floating platform, a drive device connected to the floating platform, and a harvesting device disposed at the end of the floating platform. The drive device includes a front drive assembly and a rear drive assembly connected to the floating platform. The front drive assembly is provided in two sets and is symmetrically disposed on both sides of the floating platform at one end near the harvesting device.

[0006] The rear drive assembly is located at the end of the floating platform away from the harvesting device, and includes a first bracket rotatably connected to the floating platform, a first drive assembly connected to the first bracket and the floating platform, and a first drive wheel connected to the first bracket. The first drive assembly can drive the first bracket to rotate on the floating platform, so that the first drive wheel performs ground walking and water driving actions.

[0007] Preferably, the first drive assembly includes a first linear actuator rotatably connected to the floating platform, a first link rotatably connected to the first linear actuator, and an end of the first link away from the first linear actuator rotatably connected to a first bracket.

[0008] Preferably, there are two first drive wheels, which are symmetrically arranged on both sides of the first bracket.

[0009] Preferably, the first drive wheel includes a drive motor connected to a first bracket, a hub connected to the drive motor, and multiple blades connected to both sides of the hub. The multiple blades on each side are arranged in a circle, the circle containing the multiple blades is concentric with the hub, and the outer diameter of the circle is smaller than the outer diameter of the hub.

[0010] Preferably, the hub includes a rim and spokes, the spokes extend laterally from the center and are connected to a sleeve, and the drive motor is disposed inside the sleeve; the blades are connected to the outer ring of the sleeve and are also connected to the spokes, and two adjacent blades form an outer ring and an open hollow area on the side away from the spokes.

[0011] Preferably, a wheel rim is connected to the outer corner of the blade away from the spoke, and a connecting plate extends on both sides of the outer edge in the direction of rotation of the drive wheel. The two ends of the connecting plate are connected to the wheel rim and the bushing, respectively.

[0012] Preferably, the outer rim of the wheel hub is connected to a tire tread, and the tire tread is provided with raised patterns.

[0013] Preferably, the front drive assembly includes a second bracket connected to the floating platform, a second drive wheel connected to the second bracket, and a second linear drive connected to the second bracket;

[0014] The second support is a multi-link structure, which can drive the second drive wheel to move up or down under the drive of the second linear actuator to perform underwater driving or ground walking actions.

[0015] Compared with the prior art, the advantages of this utility model are:

[0016] (1) With the amphibious drive device, when the floating platform is in the water, the first drive wheel and the second drive wheel can rotate upward to the water surface and drive the movement by the rotation of the paddle blades; when on land or in shallow water, the first drive wheel and the second drive wheel can rotate downward to lift the floating platform and drive it to move, so that no manual handling is required when transferring or transporting it on the road, which greatly reduces the labor intensity of manual labor.

[0017] Furthermore, the amphibious setup allows for direct transport of harvested aquatic plants to the road surface, making manual collection of aquatic plants easier.

[0018] (2) The two front drive components are set independently, so that when driving in water, the floating platform can be turned by adjusting the draft of the two second drive wheels respectively;

[0019] (3) The spokes in the hub make the hub almost solid, which strengthens the drive wheel. In addition, the blades are connected to the sleeve, spokes, wheel rim and connecting plate at the same time, which also serves as the hub skeleton, further strengthening the hub and preventing the hub from deforming when walking on the ground.

[0028] The present invention will be further described in detail below with reference to specific embodiments:

[0029] like Figure 1 As shown, this utility model is applied to harvesting aquatic plants in aquaculture ponds. By installing an amphibious drive device on a floating platform, the platform can float on the water surface and automatically drive and turn, moving in shallow water or on land. Specifically,

[0030] A drive device for an amphibious aquatic plant harvester, the harvester includes a floating platform 1, a drive device connected to the floating platform 1 and a harvesting device 2 disposed at the end of the floating platform 1, the drive device including a front drive assembly 3 and a rear drive assembly 4 connected to the floating platform 1.

[0031] The rear drive assembly 4 is located at the end of the floating platform 1 furthest from the harvesting device 2. It includes a first support 41 rotatably connected to the floating platform 1, a first drive assembly 42 connected to both the first support 41 and the floating platform 1, and first drive wheels 43 connected to the first support 41. Specifically, the first drive assembly 42 includes a first linear actuator 421 rotatably connected to the floating platform 1, a first connecting rod 422 rotatably connected to the first linear actuator 421, and one end of the first connecting rod 422 furthest from the first linear actuator 421 rotatably connected to the first support 41. Two first drive wheels 43 are provided and symmetrically arranged on both sides of the first support 41.

[0032] In this embodiment, the two ends of the first support 41 are respectively rotatably connected to the floating platform 1 to increase the stability of the first support 41; the first connecting rod 422 is connected at the center of the first support 41. When the first linear actuator 421 performs the pushing action, it can push the first support 41 to rotate through the first connecting rod 422, and at the same time drive the first drive wheel 43 to rotate downward until the first support 41 is in a vertical state. At this time, the first drive wheel 43 performs the walking action on land or in the silt of shallow water area; when the first linear actuator 421 performs the pulling action, it can drive the first support 41 to rotate in the opposite direction through the first connecting rod 422, and at the same time drive the first drive wheel 43 to rotate upward. The draft of the first drive wheel 43 can be adjusted according to the draft of the floating platform 1 to achieve the purpose of driving the floating platform 1 to walk in the water.

[0033] like Figure 2 As shown, the first drive wheel 43 needs to move on land and drive in water. Therefore, the first drive wheel 43 includes a drive motor 44 connected to the first bracket 41, a hub 45 connected to the drive motor 44, and multiple blades 46 connected to both sides of the hub 45. The multiple blades 46 on each side are arranged in a circle, and the circle containing the multiple blades 46 is concentric with the hub 45, and the outer diameter is smaller than the outer diameter of the hub 45.

[0034] The drive motor 44 can be a hub motor and needs to be waterproofed, which is existing technology and will not be described in detail in this embodiment.

[0035] The wheel hub 45 includes a rim 451 and spokes 452. The outer ring of the spokes 452 is completely connected to the inner ring of the rim 451 to ensure the strength of the rim 451. Of course, the edges of the spokes 452 can also be hollowed out according to the actual situation. A sleeve 453 extends from the center of the spokes 452 to the side and is connected to it. The drive motor 44 is located inside the sleeve 453, and the sleeve 453 protects the drive motor 44.

[0036] Multiple blades 46 are evenly arranged and connected to the outer ring of the sleeve 453, and simultaneously connected to the spokes 452. Two adjacent blades 46 form an outer ring and an open fan-shaped hollow area on the side away from the spokes 452. A wheel rim 461 is connected to the outer corner of the blade 46 away from the spokes 452. A connecting plate 462 extends from the outer edge towards both sides of the drive wheel rotation direction, and the two ends of the connecting plate 462 are connected to the wheel rim 461 and the sleeve 453, respectively. In this embodiment, in addition to driving in water, the blades 46, connecting plates 462, wheel rim 461, and sleeve 453 also serve as the frame of the hub 45, further strengthening the hub 45.

[0037] The outer rim of the wheel hub 45 is connected to the tread 454, which has raised treads. This makes it easier to travel on land.

[0038] like Figure 3 As shown, two sets of front drive components 3 are provided, symmetrically arranged on both sides of the floating platform 1 near the harvesting device 2. Each front drive component 3 includes a second support 31 connected to the floating platform 1, a second drive wheel 32 connected to the second support 31, and a second linear actuator 33 connected to the second support 31. The second support 31 is a multi-link structure, which can drive the second drive wheel 32 upwards or downwards under the drive of the second linear actuator 33 to perform underwater driving or ground walking actions. In this embodiment, the structure of the second drive wheel 32 is basically the same as that of the first drive wheel 43, and will not be described again. The two front drive components 3 are independently arranged. When driving in water, the floating platform 1 can be steered by adjusting the draft of the two second drive wheels 32 respectively.

[0039] In addition, two second drive wheels 32 are located on both sides of the floating platform 1, and two first drive wheels 43 are located at the rear of the floating platform 1. The different wheel spacing makes the floating platform 1 more stable when moving on land. At the same time, when encountering obstacles such as nets during the relocation of aquaculture ponds, the second drive wheels 32 can be driven one by one to lift them and cross the obstacles.
