Description

Technical Field

[0001] The present invention relates to the technical field of agricultural machinery, and in particular to a fully automatic aquatic weed harvesting 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, river crabs are mostly cultivated by planting grass. Water grass is an indispensable habitat, hiding place, and molting place for river crabs. However, it is easy for water grass 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, water grass extending out of the water surface will hinder the generation of waves and is not conducive to the entry of oxygen in the air into the water body. Therefore, water grass needs to be trimmed. In addition, in the standards for building high-standard crab ponds, there are also clear requirements for supporting equipment, including a low damage rate to crabs when the equipment is running; requirements for trimmed water grass, such as consistent top depth, neat sides, or trimming into various ornamental shapes.

[0003] In the prior art, such as the small boat-mounted aquatic grass harvester with patent number CN201110074463.9 that can be quickly disassembled and assembled; the intelligent energy-saving harvesting device and its use method with patent number CN202011136414.9, etc., the harvesting devices are all scissor-type, set at the end of the harvesting conveyor belt, and cut the aquatic grass as the floating platform moves forward. However, in the crab pond, crabs will randomly inhabit the aquatic grass, and the scissor-type setting is easy to cause damage to the crabs, and can only harvest the top of the aquatic grass, and the use scene is limited. For example, a portable aquatic grass harvesting device with patent number CN202210092169.9 is provided with a horizontal cutter and a vertical cutter to achieve the trimming of the side of the aquatic grass, but it needs to set up multiple drive devices, the structure is relatively complex, and the overall load of the harvesting equipment is increased; it is also impossible to trim the aquatic grass at other angles, and the use scene is still limited.

[0004] In addition, when the aquatic plants are harvested, the crabs may be transported along with the aquatic plants by the transport assembly. The transport mechanism in the prior art usually adopts a belt-type transport, and some crabs cannot escape, resulting in the loss of crabs.

[0005] Therefore, how to achieve accurate trimming of aquatic plants in aquaculture ponds and reduce or avoid damage to river crabs is a problem that technicians in this field need to consider. Summary of the invention

[0006] The purpose of the present invention is to provide a fully automatic aquatic plant harvesting equipment for aquaculture ponds to solve the problems in the prior art of damaging river crabs by pruning aquatic plants in aquaculture ponds and failing to accurately control the pruning of aquatic plants.

[0007] The technical solution of the present invention is: a fully automatic aquatic weed harvesting device for a breeding pond, comprising a floating platform, wherein the floating platform is connected to a transmission component through a first connection component and a second connection component, and the end of the transmission component away from the floating platform is connected to a harvesting component; The harvesting component includes a rotating component connected to the end of the conveying component away from the floating platform, and a cutting component connected to the rotating component. The cutting component includes a mounting plate connected to the rotating component, a first driver is connected to the mounting plate, and a first connecting rod is slidably connected through a slider; a rack is connected to the first connecting rod, and the first driver drives the first connecting rod to reciprocate on the slider, thereby driving the rack to reciprocate to cut the aquatic plants.

[0008] The first driver is connected to a second connecting rod, the second connecting rod is connected to the first connecting rod through a third connecting rod, and the third connecting rod is rotatably connected to the first connecting rod and the second connecting rod; The first driver drives the second connecting rod to rotate, and drives the first connecting rod to reciprocate on the slider through the third connecting rod.

[0009] The mounting plate is provided with a protective cover, and the protective cover is provided with a long strip-shaped notch; The first connecting rod is arranged in the protective cover, and both ends of the first connecting rod are connected to the rack through a fourth connecting rod extending out of the notch.

[0010] Preferably, the rotating assembly comprises a support rod connected to the frame of the transmission assembly, the mounting plate is rotatably connected to the support rod; the support rod is connected to a second driver and is connected to a push rod via a guide sleeve; One end of the push rod away from the second driver is connected to the mounting plate through a fifth connecting rod, and the fifth connecting rod is rotatably connected to the mounting plate and the push rod; The second driver is connected to the push rod and can drive the push rod to slide on the guide sleeve, and then drive the mounting plate to rotate on the support rod through the fifth connecting rod.

[0011] Preferably, the conveying assembly includes two groups of chains symmetrically arranged on a frame, the chains are connected by a plurality of parallel and spaced conveying rods, and the two groups of chains rotate synchronously and drive the plurality of conveying rods to rotate.

[0012] Preferably, a guide plate is provided on the frame, a guide groove is formed on the guide plate, and the chain is embedded in the guide groove.

[0013] Preferably, the first connecting assembly comprises a first bracket connected to the floating platform, a sixth connecting rod whose middle portion is rotatably connected to the first bracket, one end of the sixth connecting rod is rotatably connected to the frame, and the other end is rotatably connected to the floating platform via a third driver; The third driver can drive the sixth connecting rod to rotate on the first bracket, thereby driving the transmission component to move.

[0015] Compared with the prior art, the advantages of the present invention are: (1) The reciprocating motion of the rack cuts off the water plants. In crab pond farming, even if the rack contacts the crab, it will only push the crab away, thus avoiding damage to the crab and reducing the crab injury rate; The conveying assembly is arranged by rotating multiple conveying rods in parallel, so that water plants are not easily piled up during transmission. Crabs can escape by crawling on the surface of water plants or through the gaps between the conveying rods, further reducing the loss of crabs.

DETAILED DESCRIPTION

[0018] The present invention is further described in detail below in conjunction with specific embodiments: like Figure 1-Figure 7 As shown, the present invention is applied to the harvesting of waterweeds in crab ponds and other breeding ponds. In the breeding ponds of river crabs, waterweeds are planted in the middle part of the crab ponds. When harvesting waterweeds, the top and sides of the waterweeds need to be trimmed to prevent the waterweeds from reaching the water surface or growing wildly to the sides. When trimming the waterweeds, the following issues need to be noted: avoid damage to river crabs; when collecting waterweeds and river crabs are mistakenly collected, the river crabs need to be able to escape by themselves; in addition, in the construction of high-standard crab ponds, the harvested waterweeds should not only be suitable for the growth of river crabs, but also have ornamental value.

[0019] The specific technical solution is: a fully automatic waterweed harvesting device for aquaculture ponds, comprising a floating platform 1, the floating platform 1 is connected to a transmission component 4 through a first connection component 2 and a second connection component 3, and the end of the transmission component 4 away from the floating platform 1 is connected to a harvesting component 5. The floating platform 1 is driven to float in the crab pond; the harvesting component 5 cuts the waterweed at or below the water surface; and the transmission component 4 then transmits the cut waterweed to the floating platform 1 for collection.

[0020] like Figure 5-Figure 7As shown, the harvesting assembly 5 includes a rotating assembly 51 connected to the end of the conveying assembly 4 away from the floating platform 1, and a cutting assembly 52 connected to the rotating assembly 51. The cutting assembly 52 includes a mounting plate 521 connected to the rotating assembly 51, a first driver (not shown) is connected to the mounting plate 521, and a first connecting rod 522 slidably connected through a slider 524. A protective cover 523 is also provided on the mounting plate 521, and the slider 524 and the first connecting rod 522 are both arranged inside the protective cover 523. Two long strip notches 5231 are provided on the protective cover 523. Both ends of the first connecting rod 522 are connected to a fourth connecting rod 525 perpendicular to it, and the fourth connecting rod 525 extends out of the protective cover 523 through the notch 5231, and a rack 526 is connected between the two fourth connecting rods 525.

[0021] The first driver is connected to a second connecting rod 527 , which is connected to the first connecting rod 522 via a third connecting rod 528 , and the third connecting rod 528 is rotationally connected to the first connecting rod 522 and the second connecting rod 527 .

[0022] In this embodiment, two groups of harvesting components 5 are provided, which are symmetrically connected to the ends of the conveying component 4. When the rotating components 51 on both sides respectively drive the cutting components 52 to be parallel to the ends of the conveying component 4, the cutting components 52 on both sides are in the same straight line.

[0023] The first driver may be a motor, which is fixedly connected to the mounting plate 521, and its driving end is connected to the second connecting rod 527. The first driver drives the second connecting rod 527 to rotate, so that one end of the third connecting rod 528 rotates accordingly, and the other end drives the first connecting rod 522 to reciprocate on the slider 524, while the fourth connecting rod 525 reciprocates at the long strip notch 5231, thereby driving the rack 526 to reciprocate to cut the waterweed.

[0024] It should be noted that the rack 526 can be a thin steel plate with spikes, or a rope saw formed by a toothed wire rope. In practical applications, the aquatic plants in crab ponds are mainly elodea, black grass, etc., and the stems are fragile and easy to break, which can be easily cut by the high-speed reciprocating motion of the rack 526.

[0025] In other embodiments, the waterweed can be cut by driving the ring-shaped rope saw to rotate. Specifically, at least two pulleys are arranged on the mounting plate 521, and the rope saw is wound around the pulleys; the first driver drives the pulley to rotate, driving the rope saw to rotate at high speed, thereby cutting the waterweed.

[0026] The rotating assembly 51 includes a support rod 511 connected to the frame 41 of the transmission assembly 4, and a mounting plate 521 is rotatably connected to the support rod 511; the support rod 511 is connected to a second driver (not shown) and a push rod 513 via a guide sleeve 512. The end of the push rod 513 away from the second driver is connected to the mounting plate 521 via a fifth connecting rod 514, and the fifth connecting rod 514 is rotatably connected to the mounting plate 521 and the push rod 513.

[0027] In this embodiment, the support rod 511 and the frame 41 are detachably connected, and the connection position of the support rod 511 and the frame 41 can be adjusted according to different use conditions, so that the cutting assembly 52 is away from or close to the transmission assembly 4. The second driver can be an electric push rod or other device capable of driving linear motion. The second driver is connected to the push rod 513 and can drive the push rod 513 to slide on the guide sleeve 512, and then drive the mounting plate 521 to rotate on the support rod 511 through the fifth connecting rod 514.

[0028] like Figure 2-Figure 4 As shown, the conveying assembly 4 includes two groups of chains 42 symmetrically arranged on a frame 41, and the chains 42 are connected by a plurality of parallel and spaced conveying rods 43, and the two groups of chains 42 rotate synchronously and drive the plurality of conveying rods 43 to rotate. A guide plate 44 is arranged on the frame 41, and a guide groove 45 is formed on the guide plate 44, and the chain 42 is embedded in the guide groove 45.

[0029] In this embodiment, the chain 42 will loosen after long-term use, and the guide groove 45 can support the chain to prevent the chain 42 from loosening, so as to ensure the stability of transmission. When the river crab escapes from the transmission component 4, it may be clamped on the chain 42 and cause damage, and the guide groove 45 prevents the chain 42 from being exposed and avoids damage to the river crab. There is a gap between two adjacent transmission rods 43, which makes it easier for the river crab to escape.

[0030] In addition, in other embodiments, a claw (not shown) may be connected to the transmission rod 43 to hook the aquatic plants and ensure effective transmission of the aquatic plants.

[0031] like Figure 1-Figure 2 As shown, the first connecting assembly 2 includes a first bracket 21 connected to the floating platform 1, a sixth connecting rod 22 whose middle part is rotatably connected to the first bracket 21, one end of the sixth connecting rod 22 is rotatably connected to the frame 41, and the other end is rotatably connected to the floating platform 1 through a third driver 23.

[0032] The second connection assembly 3 includes a seventh connecting rod 31 rotatably connected to the end of the floating platform 1, and one end of the seventh connecting rod 31 away from the floating platform 1 is connected to the transmission assembly 4 through a guide block 32 and a slide rail 33, and the guide block 32 is rotatably connected to the seventh connecting rod 31, and the slide rail 33 is fixedly connected to the frame 41. The seventh connecting rod 31 is also rotatably connected to the floating platform 1 through a fourth driver 34.

[0033] In this embodiment, two groups of the first connecting assembly 2 and the second connecting assembly 3 are provided, which are respectively provided on both sides of the frame 41 to ensure the stability of the adjustment process of the transmission assembly 4. However, the third driver 23 and the fourth driver 34 can each be provided with one, and the two can drive the first connecting assembly 2 and the second connecting assembly 3 through other connecting rod structures according to the actual installation position. This is the prior art and will not be repeated in this embodiment.

[0034] The adjustment process is as follows: the third driver 23 drives the sixth connecting rod 22 to rotate on the first bracket 21, so that the transmission component 4 slides on the guide block 32 along the direction of the slide rail 33 to perform an extension or retraction action; when the fourth driver 34 drives the seventh connecting rod 31 to rotate, the guide block 32 drives the transmission component 4 to rotate along the rotation connection between it and the sixth connecting rod 22, so that the harvesting component 5 moves upward or downward, thereby adjusting the harvesting length of the aquatic plants by the harvesting component 5. It should be noted that when the third driver 23 drives the movement, in addition to moving along the direction of the slide rail 33, the transmission component 4 also rotates along the connection between the guide block 32 and the seventh connecting rod 31, so that the harvesting component 5 moves slightly upward or downward. This movement process can be amplified or offset by the adjustment of the second connecting component 3, so it can be ignored. In addition, during the process of harvesting aquatic plants, as the amount of aquatic plants on the floating platform 1 increases, the draft depth increases, and the draft depth of the harvesting component 5 will also increase synchronously, causing the harvested length of the aquatic plants to gradually increase. Therefore, the first connecting component 2 and the second connecting component 3 can be adjusted to allow the harvesting component 5 to move upward relative to the floating platform 1 to ensure the stability of the length of the harvested aquatic plants.

[0035] 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.
