Description

Technical Field

[0001] The invention relates to the technical field of agricultural machinery, and in particular to an amphibious aquatic weed cleaning device for aquaculture ponds. Background Art

[0002] With the development of social economy and the improvement of people's living standards, the degree of agricultural mechanization and electrification has been continuously deepened, and the modernization and economic management of river crab farming has been continuously improved. However, at present, since river crabs are mostly farmed by planting grass, aquatic plants are indispensable habitats, hiding places, and molting places for river crabs. However, it is easy for aquatic plants to grow too vigorously and cover the entire breeding water surface, which can easily cause insufficient dissolved oxygen in the water body and affect the growth of river crabs. Moreover, aquatic plants extending out of the water surface will hinder the formation of waves and are not conducive to the entry of oxygen in the air into the water body. Therefore, aquatic plants need to be trimmed.

[0003] In the prior art, the harvesting equipment of aquatic plants usually adopts a floating platform, on which a harvesting device is arranged for harvesting. When transferring, the aquatic plants on the floating platform need to be unloaded to the shore first, then the harvesting device needs to be salvaged to the shore, and finally transported to other breeding ponds. The whole process needs to be done manually, which is labor-intensive and the operation safety cannot be guaranteed. In addition, the harvesting device also needs to be driven forward and turned manually when working in the water, which is inconvenient to use and affects the harvesting efficiency of aquatic plants.

[0004] In the prior art, for example, a paddle wheel drive device of a surface cleaning boat with patent number CN201710303315.7 is driven in water by a paddle wheel mechanism, but its strength cannot support walking on land, and its usage scenarios are limited; for example, a multifunctional spherical drive wheel for an amphibious vehicle with patent number CN202011319543.1, if used for harvesting aquatic plants, has a complex structural design, increases the mass of the drive wheel itself, reduces the carrying capacity of the floating platform, and the design of the opening and closing paddle blades easily causes the aquatic plants to get stuck and affect the drive; for example, a foldable inflatable electric amphibious vehicle with patent number CN202410891690.8, if used for harvesting aquatic plants, as the load of the floating platform increases during the harvesting of aquatic plants, the draft depth of the drive wheel increases, which will affect the driving ability; in addition, a separate steering wheel mechanism needs to be provided to turn the floating platform and turn around, which increases the load of the floating platform itself. In addition, the existing amphibious drive wheels are usually made of stainless steel or other hard alloy materials to ensure strength and avoid deformation when walking on land, but this will further increase the load of the floating platform. Therefore, how to set the drive device so that the waterweed harvesting equipment can be amphibious and ensure the lightness and stability of the amphibious drive is a problem that technicians in this field need to consider.

[0020] Compared with the prior art, the advantages of the present invention are:

[0021] (1) Through the design of the amphibious driving mechanism, when in water, the first driving wheel and the second driving wheel can be adjusted to move upward to the water surface, and the driving movement is carried out by the rotation of the blades; when on land or in shallow water, the first driving wheel and the second driving wheel can be adjusted to move downward, and the tread can be pressed against the ground to carry out walking on land;

At the same time, the aquatic plants temporarily stored on the floating platform can also be directly transported to land and unloaded on land, which greatly reduces the labor intensity of manual labor and increases the safety of operation.

[0023] (2) The movement speed of the harvesting device can be adjusted by adjusting the draft and rotation speed of the second driving wheel; the turning and U-turn movements of the harvesting device can be achieved by adjusting the draft of the first driving wheels on both sides of the floating platform respectively; when harvesting aquatic plants, as the load of aquatic plants on the floating platform increases, the first driving wheel and the second driving wheel can be adjusted to move upward to ensure the driving efficiency of the harvesting device in the water;

[0024] It can also be operated by remote control, which further reduces the labor intensity of manual work and increases the safety of operation;

[0025] (3) In the setting of the driving wheel, the blades are connected to the hub and the sleeve at the same time, which strengthens the hub and prevents the hub from deforming when running on land. In addition, the setting of the wing plate and the wheel frame further strengthens the strength of the hub, so that the design of the driving wheel can use lighter materials such as aluminum alloy to reduce the load of the floating platform.

[0026] The wing plate can cut and break the nearby water plants during the rotation of the driving wheel to prevent the water plants from entangling the driving wheel and affecting the driving ability. At the same time, the wheel frame can also prevent the blades from hitting crabs and other farmed animals during the driving in the water, thus reducing the damage to the farmed aquatic products.

[0027] (4) The two first drive wheels and the two second drive wheels have different wheelbases, and the first drive wheel with a larger wheelbase is arranged on the side close to the harvesting device (the side with a larger load), which increases the walking stability.

[0038] The present invention is further described in detail below in conjunction with specific embodiments:

[0039] like Figure 1-Figure 5 As shown, the present invention is applied to the harvesting of waterweeds in aquaculture ponds. By arranging an amphibious driving device on a floating platform, the harvesting equipment can be driven in water and can also walk on land, thereby reducing the labor intensity of manually salvaging, carrying, and putting the harvesting equipment into water during the transfer. Moreover, the harvested waterweeds can be directly transported to the shore, and there is no need for manual transportation of the waterweeds on the shore, thereby reducing the labor intensity and improving the safety of the operation.

[0040] Specifically: An amphibious aquatic plant cleaning equipment for aquaculture ponds includes a floating platform 1, a harvesting device 2 connected to the end of the floating platform 1, the floating platform 1 is connected to a first driving mechanism 3 and a second driving mechanism 6, the first driving mechanism 3 is provided with two symmetrical groups and respectively connected to the two sides of the floating platform 1 close to the harvesting device 2; the second driving mechanism 6 is connected to the end of the floating platform 1 away from the harvesting device 2.

[0041] like Figure 3-Figure 5 As shown, the first driving mechanism 3 is provided with a first adjusting assembly 4 and a first driving wheel 5 .

[0042] The first driving wheel 5 includes a first driver 51 connected to the first adjustment component 4, and a land driving component 52 and a water driving component 53 are connected to the first driver 51, wherein two groups of water driving components 53 are provided and symmetrically arranged on both sides of the land driving component 52. The land driving component 52 includes a spoke 521 connected to the first driver 51, and a hub 522 is provided on the outer ring of the spoke 521. The water driving component 53 is provided in two groups and symmetrically arranged on both sides of the land driving component 52, and includes a sleeve 531 connected to the spoke 521, the first driver 51 is arranged in the sleeve 531, and a plurality of blades 532 are connected to the outer periphery of the sleeve 531, and at least a part of the side of the blade 532 away from the sleeve 531 is connected to the inner side of the hub 522.

[0043] In this embodiment, the spoke 521 is configured to be plate-shaped, the sleeve 531 is barrel-shaped, and the bottom surface of the sleeve 531 is fitted and connected to the spoke 521. The sleeve 531 and the hub 522 are concentrically arranged, and the plurality of blades 532 are evenly arranged, and the plane where they are located coincides with the axis of the sleeve 531. The first driver 51 can be a waterproof motor fixedly connected to the first adjustment component 4. The first driver 51 is arranged in the sleeve 531, and its driving end can be fixedly connected by bolts that penetrate the sleeve 531 and the spoke 521 at the same time, so that the sleeve 531 not only protects the first driver 51, but also strengthens the spoke 521 by fitting with the spoke 521. The outer ring of the hub 522 is provided with a tread 523, and the tread 523 can be other soft materials such as rubber to increase the buffering and shockproof ability of walking on land.

[0044] It should be noted that when walking on land, the total mass of the entire harvesting equipment and the waterweed on the floating platform 1 is relatively large. In order to prevent the hub 522 from deforming, the blades 532 are connected to the sleeve 531 and the hub 522 at the same time, supporting the hub 522 and increasing the strength of the hub 522. The sleeve 531 is a barrel-shaped sleeve with a gradually enlarged opening end, which can increase the strength of the sleeve 531 and further increase the support strength of the hub 522. In other embodiments, the blades 532 can also be connected to the spokes 521 at the same time, so that the strength of the hub 522 is further enhanced.

[0045] The end of the blade 532 away from the spoke 521 is provided with a wing plate 533, which is symmetrically arranged on both sides of the blade 532, and the wing plate 533 and the blade 532 are perpendicular to each other. One end of the wing plate 533 is connected to the sleeve 531, and the end away from the sleeve 531 is connected to the wheel frame 534; the wheel frame 534 is annular, and the outer diameter is smaller than the outer diameter of the hub 522.

[0046] In this embodiment, the wing plate 533 is provided to, on the one hand, cut and crush nearby aquatic plants when the first driving wheel 5 rotates, thereby preventing the aquatic plants from being entangled on the driving wheel and affecting the driving ability; on the other hand, it strengthens the strength of the blade 532, further increasing the supporting ability of the blade 532 on the hub 522.

[0047] In a crab pond, crabs will randomly inhabit in water plants. During the water plant cutting process, the rotation of the blade 532 may cause damage to the crab. Therefore, a wheel frame 534 is provided on the outer ring of the blade 532 to prevent the crab from directly colliding with the blade and causing damage. At the same time, the setting of the wheel frame 534 also further strengthens the blade 532 and the wing plate 533.

[0048] The first adjustment assembly 4 includes a first connecting rod 41 fixedly connected to the floating platform 1, and the first connecting rod 41 is rotatably connected to a second driver 42 and a triangular arm 43. The end of the second driver 42 away from the first connecting rod 41 is rotatably connected to the triangular arm 43; the triangular arm 43 is also connected to the first driving wheel 5 through a second connecting rod 44.

[0049] In this embodiment, the second driver 42 may be an electric push rod or other device capable of driving a linear motion. The second driver 42 may drive the triangular arm 43 to rotate on the first connecting rod 41, thereby driving the first driving wheel 5 to move upward or downward.

[0050] In order to further increase the stability of the movement of the second driver 42, the second link 44 and the triangular arm 43 are set to be rotatably connected. The second link 44 extends at a certain angle to the end away from the first driving wheel 5 to form a third link 441. The third link 441 is connected to the first link 41 through the fourth link 45. The fourth link 45 is rotatably connected to the third link 441 and the first link 41, and the connection between the fourth link 45 and the first link 41 is located at the end of the first link 41 away from the connection between the second driver 42 and the first link 41. When driving the first driving wheel 5 to move up and down, the second driver 42 drives the triangular arm 43 to rotate along the connection between it and the first link 41; at the same time, it drives the fourth link 45 to rotate relative to the third link 441 and the first link 41 at the same time, so that the first driving wheel 5 moves up or down.

[0051] like Figure 2 As shown, the second driving mechanism 6 is provided with a second adjustment assembly 7 and two coaxial second driving wheels 8. The second adjustment assembly 7 includes a first bracket 71 connected to the second driving wheel 8, and the first bracket 71 is also rotatably connected to the end of the floating platform 1 away from the harvesting device 2. The first bracket 71 is connected to the third driver 73 through the fifth connecting rod 72, and the fifth connecting rod 72 is rotatably connected to the first bracket 71 and the third driver 73; the end of the third driver 73 away from the fifth connecting rod 72 is rotatably connected to the floating platform 1.

[0052] In this embodiment, the second drive wheel 8 has the same structure as the first drive wheel 5, which will not be described in detail in this embodiment. The third driver 73 can be an electric push rod or other device capable of driving linear motion. When the third driver 73 is driven, the first bracket 71 is driven to rotate along the connection between it and the floating platform 1 through the fifth connecting rod 72, thereby driving the two second drive wheels 8 to move upward or downward.

[0053] The first bracket 71 includes support rods 711 connected to the two second driving wheels 8 respectively, and a support frame 712 connected to the two support rods 711. The ends of the two support rods 711 away from the second driving wheels 8 are both rotatably connected to one end of the floating platform 1; the fifth connecting rod 72 is rotatably connected to the center of the support frame 712. In this embodiment, in order to ensure the strength of the support frame 712 after being connected to the support rod 711, a U-shaped clamp can be used for fixed connection.

[0054] In addition, in order to ensure the walking stability of the harvesting equipment, the wheelbase of the two first drive wheels 5 is greater than the wheelbase of the two second drive wheels 8. When the harvesting device 2 is walking, if it encounters an obstacle, the second drive wheel 8 can be lifted one by one by the second drive mechanism 6 to cross the obstacle. The floating platform, the first drive mechanism and the second drive mechanism in this embodiment can all be made of aluminum alloy, which is light in weight and has sufficient strength. In addition, through the above-mentioned structural design of the first drive wheel and the second drive wheel, the strength of the wheel hub is greatly enhanced, and the drive wheel made of aluminum alloy can meet the land driving requirements of the harvesting device after being fully loaded with aquatic plants.

[0055] The above embodiments are only for illustrating the technical concept and features of the present invention, and their purpose is to enable people familiar with this technology to understand the content of the present invention and implement it accordingly, and they cannot be used to limit the scope of protection of the present invention. For those skilled in the art, it is obvious that the present invention is not limited to the details of the above exemplary embodiments, and the present invention can be implemented in other specific forms without departing from the spirit or basic features of the present invention. Therefore, no matter from which point of view, the embodiments should be regarded as exemplary and non-restrictive. The scope of the present invention is limited by the attached claims rather than the above description, and it is intended to include all changes within the meaning and scope of the equivalent elements of the claims in the present invention.
