Abstract
Description
Technical Field
[0001] This application relates to the field of agricultural machinery, and in particular to a structure for harvesting aquatic plants in shrimp and crab ponds. 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] Existing aquatic plant thinning structures are generally achieved through cutting mechanisms, such as cutting strips. This type of cutting cannot achieve the function of thinning plants, and the cutting mechanism is relatively complex and can easily damage shrimp and crabs. Utility Model Content
[0004] The purpose of this invention is to provide a structure for harvesting aquatic plants in shrimp and crab ponds, which can thin or cut aquatic plants as needed, while reducing damage to shrimp and crabs.
[0005] To achieve the above objectives, the present invention provides the following technical solution.
[0006] This application discloses a structure for harvesting aquatic plants in shrimp and crab ponds, including a cutting mechanism installed at the front end of a front collection plate. The cutting mechanism includes two cutting boxes arranged opposite each other, with one end of each cutting box rotatably installed at the bottom of the front end of the front collection plate.

[0007] Preferably, in the above-mentioned aquatic plant harvesting structure for shrimp and crab ponds, the cutting box is mounted on the front collecting plate with a 360° rotatable configuration around one end.
[0008] When the two cutting boxes rotate towards each other to a horizontal position, they harvest and collect the aquatic plants within the width range of the front collection plate.
[0009] When the two cutting boxes are rotated to a horizontal position in opposite directions, they cut the aquatic plants outside the width range of the front collection plate and thin out the aquatic plants within the width range of the front collection plate.
[0010] When the two cutting boxes are rotated to a vertical position, the aquatic plants within the width range of the front collection plate are thinned out, and the aquatic plants on both sides of the front collection plate are cut to form oxygen channels.
[0011] Preferably, in the above-mentioned aquatic plant harvesting structure for shrimp and crab ponds, when the two cutting boxes rotate horizontally towards each other, a space is formed between the two cutting boxes.

After the cam rotates, it drives the sliding rod to move back and forth, thereby driving the cutting line to move back and forth.
[0016] Preferably, in the above-mentioned aquatic plant harvesting structure for shrimp and crab ponds, the shaft of the cam is fixedly connected to one end of the flexible shaft, and the other end of the flexible shaft is connected to the rotary shaft on the front collecting plate.
[0017] Preferably, in the above-mentioned aquatic plant harvesting structure for shrimp and crab ponds, the front collecting plate includes a rotary conveyor belt capable of forward and reverse transport, and the rotary shaft drives the rotary conveyor belt to move.
[0018] Preferably, in the above-mentioned aquatic plant harvesting structure for shrimp and crab ponds, railings are formed on both sides of the front collecting plate, and the cutting mechanism is slidably installed on the railings.

[0026] The technical solutions of the present utility model will be described in detail below with reference to the accompanying drawings. Obviously, the described embodiments are only some embodiments of the present utility model, and not all embodiments. Based on the embodiments of the present utility model, all other embodiments obtained by those skilled in the art without creative effort are within the protection scope of the present utility model.
[0027] Combination Figure 1-5 As shown, the aquatic plant harvesting structure 100 for shrimp and crab ponds includes a cutting mechanism installed at the front end of the front collection plate 101. The cutting mechanism includes two cutting boxes 102 arranged opposite to each other. One end of each cutting box 102 is rotatably installed at the bottom of the front end of the front collection plate 101. A cutting line 103 is provided on the side of the cutting box 102 away from the front collection plate 101, and the cutting line 103 harvests aquatic plants.
[0028] The cutting box 102 is mounted on the front collection plate 101 by rotating 360° around one end.
[0029] When the two cutting boxes 102 rotate towards each other to a horizontal position, they harvest and collect the aquatic plants within the width range of the front collection plate 101.
[0030] When the two cutting boxes 102 rotate in opposite directions to a horizontal position, they cut the aquatic plants outside the width range of the front collection plate 101 and thin out the aquatic plants within the width range of the front collection plate 101.
[0031] When the two cutting boxes 102 are rotated to a vertical position, they thin out the aquatic plants within the width of the front collection plate 101 and cut the aquatic plants on both sides of the front collection plate 101 to form oxygen channels.
[0032] In this embodiment, aquatic plants are harvested using a cutting line, minimizing the impact on shrimp and crabs. Two cutting boxes are installed and rotated separately, allowing for different cutting or thinning functions. When cutting is needed in a specific area, the two boxes rotate towards each other to a horizontal position, and then cut the aquatic plants within that area. Figure 1 As shown; when it is necessary to cut aquatic plants outside the designated area, such as to form two channels, the plates rotate in opposite directions to a horizontal position, while the collection plate can then thin out the aquatic plants by cutting along zigzag lines, as shown. Figure 2 As shown; when kept vertical, it is generally flipped vertically upwards, vertically cutting to form oxygen channels, while simultaneously thinning the grass in the area. Of course, other angles can also be used, all of which fall within the scope of this application.
[0033] Furthermore, when the two cutting boxes 102 rotate horizontally towards each other, a space 104 is formed between the two cutting boxes 102.
[0034] In this embodiment, interference between the two is prevented during rotation.
[0035] Furthermore, the cutting mechanism is slidably installed, with its sliding direction forming an angle of 45-75° with the front collecting plate 101, and the sliding distance of the cutting mechanism is 0-900mm.
[0036] In this embodiment, the cutting mechanism is lowered to cut the aquatic plants at the bottom of the collection plate.
[0037] Furthermore, the cutting wire 103 moves back and forth along its extension direction to cut, and the two ends of the cutting wire 103 are fixed to two terminals 105. The two terminals 105 protrude to the outside of the cutting box 102, and a sliding groove 106 is formed on the cutting box 102 for the terminals 105 to move.
[0038] In this embodiment, the cutting line is driven by two terminals, and the surface of the cutting box is not exposed except for the sliding groove, which reduces the entry of aquatic plants into the cutting box. At the same time, the cutting line can reduce damage to shrimp and crabs.
[0039] Furthermore, the other end of the terminal block 105, away from the cutting wire body 103, is formed on the slide rod 107. A slider 108 is fixedly mounted on the slide rod 107, and the slider 108 is slidably installed inside the cutting box body 102. One end of the slide rod 107 is rotatably mounted on one end of a connecting piece 109, and the other end of the connecting piece 109 is rotatably mounted on a protruding part of a cam 110. After the cam 110 rotates, it drives the slide rod 107 to move back and forth, thereby driving the cutting wire body 103 to move back and forth.
[0040] In this embodiment, the reciprocating motion of the cutting line is achieved by a cam, resulting in a simple and ingenious structure.
[0041] 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.
[0042] In this embodiment, because the required cutting force is relatively small, this technical solution can be directly driven by a flexible shaft, and the power of the flexible shaft is directly driven by the rotating shaft of the collecting plate, reducing the installation of drive equipment. This technical solution is mainly used for cutting Elodea nuttallii in shrimp and crab ponds. This algae is very fragile and can be broken with just a light touch. Therefore, a flexible shaft drives a cam, which ultimately drives the cutting line to reciprocate. The design is ingenious and reduces the number of drive components.
[0043] 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.
[0044] In this embodiment, the cutting box is installed at the front end of the railing, allowing it to slide and extend deep below the water surface.
[0045] For weed thinning, the front collection plate 101 includes a rotary conveyor belt 113 capable of forward and reverse transport. The rotary conveyor belt 113 includes multiple supporting ribs 115 arranged sequentially along the transport direction. Multiple cutting zigzag lines 116 are arranged on the rotary conveyor belt 113, and the cutting zigzag lines 116 are bound to the supporting ribs 115. The cutting zigzag lines 116 are made of soft steel wire. Multiple cutting zigzag lines 116 are arranged in an X, V, or W shape.
[0046] In this embodiment, in order to achieve the grass thinning function, cutting zigzag lines are laid out on the front collection plate. Since algae are very fragile, they will automatically break when they touch the cutting zigzag lines. The zigzag lines do not need to be densely laid out. When the boat is sailing, only some aquatic plants will touch the cutting zigzag lines, thus achieving the grass thinning function and partially breaking and thinning dense aquatic plants. Figure 1-2 Multiple cutting lines form an X, V, or W shape. Figure 3 The shape is a simple V-shape, but other shapes are also within the scope of this application.

[0048] The above description is only a specific embodiment of this application. It should be noted that for those skilled in the art, several improvements and modifications can be made without departing from the principle of this application, and these improvements and modifications should also be considered within the scope of protection of this application.
