Technical Field
[0001] The present application relates to the field of agricultural machinery, and in particular to a structure for harvesting aquatic plants used in shrimp and crab 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] Existing aquatic grass weeding structures are generally cut by cutting mechanisms, such as cutting with cutting strips. This type of weeding cannot achieve the weeding function, and the cutting mechanism is relatively complex and can easily damage shrimps and crabs. Summary of the invention
[0004] The purpose of the present invention is to provide a waterweed harvesting structure for shrimp and crab ponds, which can perform different weeding or cutting on the waterweeds as needed, while reducing damage to shrimps and crabs.

[0007] Preferably, in the above-mentioned shrimp and crab pond waterweed harvesting structure, the cutting box body is rotatably mounted on the front collecting plate around one end thereof by 360 degrees. When the two cutting boxes rotate toward each other to a horizontal position, the waterweed within the width of the front collecting plate is harvested and collected; When the two cutting boxes are rotated back to back to a horizontal position, the waterweed outside the width range of the front collecting plate is cut, and the waterweed within the width range of the front collecting plate is thinned; When the two cutting boxes are rotated to a vertical state, the waterweeds within the width of the front collecting plate are cleared, and the waterweeds on both sides of the front collecting plate are cut to form an oxygen channel.
[0008] Preferably, in the above-mentioned aquatic weed harvesting structure for shrimp and crab ponds, when the two cutting box bodies are rotated horizontally toward each other, a spacing space is formed between the two cutting box bodies.

DETAILED DESCRIPTION
[0019] The following will describe the technical solutions in the embodiments of the present invention in detail in conjunction with the drawings in the embodiments of the present invention. Obviously, the described embodiments are only part of the embodiments of the present invention, not all of the embodiments. Based on the embodiments of the present invention, all other embodiments obtained by ordinary technicians in this field without creative work are within the scope of protection of the present invention.
[0020] Combination Figure 1-5 As shown, a waterweed harvesting structure 100 for shrimp and crab ponds includes a cutting mechanism installed at the front end of a front collecting plate 101, the cutting mechanism includes two cutting box bodies 102 arranged opposite to each other, one end of the two cutting box bodies 102 are respectively rotatably installed at the bottom of the front end of the front collecting plate 101, and a cutting line body 103 is provided on the side of the cutting box body 102 away from the front collecting plate 101, and the cutting line body 103 harvests the waterweed.
[0021] The cutting box body 102 is mounted on the front collecting plate 101 by rotating 360° around one end thereof. When the two cutting boxes 102 rotate toward each other to a horizontal position, the waterweed within the width of the front collecting plate 101 is harvested and collected; When the two cutting boxes 102 rotate back to back to horizontal, the waterweed outside the width range of the front collecting plate 101 is cut, and the waterweed within the width range of the front collecting plate 101 is thinned; When the two cutting boxes 102 are rotated to a vertical state, the water plants within the width of the front collecting plate 101 are cleared, and the water plants on both sides of the front collecting plate 101 are cut to form an oxygen channel.
[0022] In this embodiment, the water plants are harvested by cutting the line body, which minimizes the impact on shrimps and crabs. The two cutting boxes are respectively rotated and installed to achieve different cutting or weeding functions. When it is necessary to cut a certain area, the two boxes are rotated towards each other to be horizontal, and then the water plants in the area are cut. Figure 1As shown; when it is necessary to cut the water grass outside the area, for example, to form two channels, they are rotated back to back to horizontal, and the collecting plate can sparse the water grass by cutting the broken line, as shown Figure 2 As shown; when the vertical state is maintained, it is generally turned vertically upward, vertical cutting forms an oxygen channel, and the grass is trimmed in the area at the same time. Of course, other angles can also be used, all of which belong to the scope of this application.
[0023] Furthermore, when the two cutting box bodies 102 are rotated toward each other and horizontally, a separation space 104 is formed between the two cutting box bodies 102 .
[0024] In this embodiment, interference between the two is prevented during rotation.
[0025] Furthermore, the cutting mechanism is slidably installed, and the included angle between the sliding direction and the front collecting plate 101 is 45-75°, and the sliding distance of the cutting mechanism is 0-900mm.
[0026] In this embodiment, the cutting mechanism is sunk to cut the waterweed at the bottom of the collecting plate.
[0027] Furthermore, the cutting wire body 103 moves back and forth along its extension direction for cutting, and the two ends of the cutting wire body 103 are fixed to two connecting posts 105, and the two connecting posts 105 protrude to the outside of the cutting box body 102, and the cutting box body 102 is formed with a sliding groove 106 for the connecting posts 105 to move.
[0028] In this embodiment, the cutting line is driven by two connecting posts, and the surface of the cutting box is not exposed except for the sliding groove, which reduces the entry of aquatic plants into the interior of the cutting box. At the same time, the cutting line can reduce the damage to shrimps and crabs.
[0029] Furthermore, the other end of the terminal 105 away from the cutting line body 103 is formed on a slide bar 107, and a slider 108 is fixedly provided on the slide bar 107, and the slider 108 is slidably installed inside the cutting box body 102. One end of the slide bar 107 is rotatably installed on one end of a connecting piece 109, and the other end of the connecting piece 109 is rotatably installed on a protruding part of a cam 110. After the cam 110 rotates, it drives the slide bar 107 to reciprocate, thereby driving the cutting line body 103 to reciprocate.
[0030] In this embodiment, the reciprocating motion of the cutting wire body is achieved by the cam, and the structure is simple and ingenious.
[0031] Furthermore, the axis of the cam 110 is fixedly connected to one end of the flexible shaft 111 , and the other end of the flexible shaft 111 is connected to the rotary shaft 112 on the front collecting plate 101 .
[0032] In this embodiment, the technical solution requires a small cutting force and can be driven directly by a flexible shaft, and the power of the flexible shaft is directly driven by the rotary shaft of the collecting plate, reducing the installation of the driving device. The technical solution is mainly used to cut the Elodea in shrimp and crab ponds. The algae is very fragile and can be broken with just a light touch. Therefore, a flexible shaft is used to drive the cam, which ultimately drives the cutting line to reciprocate. The design is ingenious and reduces the number of driving components.
[0033] Furthermore, railings 114 are formed on both sides of the front collecting plate 101 , and the cutting mechanism is slidably mounted on the railings 114 .
[0034] In this embodiment, the cutting box is integrally mounted on the front end of the railing to achieve sliding and can penetrate deep below the water surface.
[0035] In order to perform grass grooming, the front collecting plate 101 includes a revolving conveyor belt 113 capable of forward and reverse conveying. The revolving conveyor belt 113 includes a plurality of supporting ribs 115 arranged in sequence along the conveying direction. A plurality of cutting fold lines 116 are arranged on the revolving conveyor belt 113, and the cutting fold lines 116 are bound to the supporting ribs 115. The cutting fold lines 116 are soft steel wires. A plurality of cutting fold lines 116 are arranged in an interlaced manner. The cutting fold lines 116 are arranged in an X, V or W shape.
[0036] In this embodiment, in order to achieve the weeding function, cutting fold lines are arranged on the front collecting plate. Since the algae are very fragile, they will automatically break when they touch the cutting fold lines. The fold lines do not need to be densely arranged. When the ship sails through the hull, only part of the aquatic plants will touch the cutting fold lines, thus achieving the weeding function and partially breaking and weeding the dense aquatic plants. Figure 1-2 For multiple cutting lines, forming X, V or W, Figure 3 It is a simple V-shape, and other shapes should certainly fall within the scope of the present application.
[0037] It should be noted that, in this article, relational terms such as first and second, etc. are only used to distinguish one entity or operation from another entity or operation, and do not necessarily require or imply any such actual relationship or order between these entities or operations. Moreover, the terms "include", "comprise" or any other variants thereof are intended to cover non-exclusive inclusion, so that a process, method, article or device including a series of elements includes not only those elements, but also other elements not explicitly listed, or also includes elements inherent to such process, method, article or device. In the absence of further restrictions, the elements defined by the sentence "comprise a ..." do not exclude the existence of other identical elements in the process, method, article or device including the elements.
[0038] The above is only a specific implementation of the present application. It should be pointed out that for ordinary technicians in this technical field, several improvements and modifications can be made without departing from the principles of the present application. These improvements and modifications should also be regarded as the scope of protection of the present application.
