Description

Technical Field

[0001] The invention relates to the technical field of gorgon fruit harvesting, in particular to a portable digging tool specially used for gorgon fruit harvesting. Background Art

[0002] Gorgon fruit is a plant of the Nymphaeaceae family, a large annual aquatic herb. Its fruit is shaped like a chicken head, commonly known as chicken head fruit. The fruit contains a large number of seeds. The seed kernel has the effects of nourishing the kidney and strengthening essence, replenishing the spleen and stopping diarrhea, removing dampness and stopping leukorrhea, and is deeply loved by the people. However, the fruit, petiole and leaves of the prickly gorgon fruit are covered with sharp thorns, making it difficult to harvest directly by hand. The current harvesting method of gorgon fruit mostly relies on manual labor, and workers need to work in water for a long time, which is harmful to the body and easily leads to diseases such as lumbar muscle strain. In addition, because gorgon fruit grows in water, the positions of mature gorgon fruit buds are different. Some are on the water surface, some are half floating on the water surface and half below the water surface, and some are even completely below the water surface, which increases the difficulty of picking.

[0003] Existing, such as Chinese patent publication number: CN117694096A, discloses an automatic water chestnut harvesting device, including a harvesting boat, one end of the harvesting boat is equipped with a harvesting mechanism and a conveying mechanism, the harvesting mechanism is installed at the input end of the conveying mechanism; the harvesting boat is equipped with a control console, the console is respectively connected to the walking mechanism, harvesting mechanism and conveying mechanism of the harvesting boat, the console is used to control the walking mechanism to drive the harvesting boat to walk on the water surface, and control the harvesting mechanism to harvest the water chestnuts on the water surface, and also control the conveying mechanism to transport the water chestnuts harvested by the harvesting mechanism to the harvesting boat.

[0004] However, the harvesting tools in the existing technology are suitable for large-scale salvage and are not suitable for small-scale personal harvesting. The current harvesting of water chestnuts mainly relies on manual labor to go into the water and use sickles, scissors and other tools to harvest mature water chestnuts. However, the existing harvesting tools themselves have a certain gravity. Workers hold the tools for a long time during operation, and it is very easy for the tools to accidentally fall into the water and sink. Once the tools fall into the water, they will quickly sink into the mud or be entangled by aquatic plants, making them difficult to salvage. As a result, people harvesting water chestnuts are likely to step on the fallen harvesting tools when working in the water, causing foot injuries to the harvesters.

[0005] Therefore, we propose a special portable digging tool for harvesting Euryale ferox, so as to solve the above-mentioned problems. Summary of the Invention

[0016] Preferably, a collecting net bag is fixedly connected between the bottoms of the plurality of positioning blocks, and the collecting net bag is used to collect the dug water chestnuts.

[0017] Compared with the prior art, the present invention has the following beneficial effects: 1. When in use, the entire digging tool is put into the water by holding the handle rod, so that the floating board floats on the water surface. After the person harvesting the water chestnuts gets into the water, he grasps the handle rod and pushes the floating board forward. In the process of moving forward, the leaf-cutting blade can cut the obstructing lotus leaves and water plants, thereby facilitating the floating board to move forward, and then facilitating the movement to the position of the water chestnuts, solving the problem of the existing digging tools falling and sinking. When harvesting, by moving the first movable picking saw and the second movable picking saw, when the stem of the water chestnut is located between the first movable picking saw, the second movable picking saw and the fixed picking saw, the saw teeth of the two intersect with the saw teeth of the fixed picking saw. When intersecting, the stem of the water chestnut will be cut off, thereby completing the digging of the water chestnuts. The buoyancy will float the digging tool on the water surface, making it easier for the harvesters to dig.

[0018] 2. When in use, push the floating plate, and the stem of the water chestnut will be limited by the arc surface of the limiting block. The second movable picking saw is fixed on the first movable picking saw. There is a gap between the two, and the fixed picking saw can just be inserted into the gap. In this process, the harvester grasps the movable crank to rotate the rotating block inside the rotating hole, thereby driving the first connecting rod to rotate. Since the first connecting rod and the second connecting rod are movably connected together by the connecting shaft, when the first connecting rod rotates, the second connecting rod will be driven to move. The movable slide can only move left and right under the limiting action of the limiting slide frame. The movable slide slides between the two rotating drums at this time, but will not fall. Therefore, when harvesting water chestnuts, the harvester only needs to turn the movable crank to complete the harvesting of the water chestnuts, which is light and labor-saving.

[0019] 3. During use, when the first movable picking saw is close to the fixed picking saw, the second connecting pipe sleeve is away from the first connecting pipe sleeve. When the first movable picking saw, the second movable picking saw and the fixed picking saw cross-cut the mature water chestnuts, the collecting net bag is in an open state. The weight of the mature water chestnuts will sink and fall directly into the collecting net bag, thereby preventing the dug mature water chestnuts from sinking to the bottom of the water. Among them, the gravity of the collecting net bag full of water chestnuts is smaller than the buoyancy of the first hollow floating block and the second hollow floating block, so it will not sink even if it is full. The movement of the two mounting rods will drive the collecting net bag to open and close. When the first movable picking saw, the second movable picking saw and the fixed picking saw are separated, the two mounting rods will be close to each other, and then the collecting net bag will be tightened, which can prevent the collected water chestnuts from overflowing from the collecting net bag due to buoyancy.

After the person who harvests the water chestnuts gets into the water, he grasps the handle rod 104 and pushes the floating board 101 forward. In the process of moving forward, he will encounter large lotus leaves and water plants. At this time, the leaf cutting blade 106 can cut the obstructing lotus leaves and water plants, thereby facilitating the pushing of the floating board 101. The floating plate 101 moves forward, and then it is convenient to move to the position of the water chestnut, which solves the problem of the existing digging tools falling and sinking. During harvesting, by moving the first movable picking saw 204 and the second movable picking saw 205, the stem of the water chestnut is located between the first movable picking saw 204, the second movable picking saw 205 and the fixed picking saw 201, so that the saw teeth of the two are crossed with the saw teeth of the fixed picking saw 201. When crossing, the stem of the water chestnut will be cut off, thereby completing the digging of the water chestnut. The buoyancy will float the digging tool on the water surface, making it easier for the harvesters to dig.

The outer surface of the floating board 101 is fixedly connected to the hand The handle rod 104 is used to facilitate the grasping of the harvesters, which is conducive to the movement of the digging tool in the water. The top of the fixed picking saw 201 is fixedly connected to a connecting frame 5 near one end, and the connecting frame 5 is fixedly installed at the bottom of the floating board 101. The top of the fixed picking saw 201 is fixedly connected to a connecting rod 4 for auxiliary connection near the other end. The top of the connecting rod 4 is fixedly connected to the bottom of the floating board 101. A fixed plate 202 is fixedly connected to the corner of one side of the fixed picking saw 201. The outer surface of the fixed plate 202 is fixedly connected to a limiting block 203, and the arc surface of the limiting block 203 is used to limit the stem of the water chestnut.

The inner wall of the limited sliding groove 207 is slidably connected to the outer surface of the fixed slide 208. The bottom of the fixed plate 202 is fixedly connected to two fixed blocks 218. The outer surfaces of the two fixed blocks 218 are rotatably connected to a rotating drum 219. A reinforcing plate 220 is fixedly connected between one end of the two fixed blocks 218.

A connecting shaft 214 is movably connected between one end of the first connecting rod 213 and one end of the second connecting rod 215.

[0026] In this embodiment, when in use, the floating plate 101 is pushed so that the stem of the water chestnut is located between the fixed picking saw 201 and the first movable picking saw 204 and the second movable picking saw 205, and then the floating plate 101 is pushed forward. The stem of the water chestnut will be limited by the arc surface of the limit block 203. At this time, the limit slide frame 206 is sleeved on the outside of the fixed slide bar 208 and slides. The fixed slide bar 208 and the limit slide groove 207 are interlocked, so that the first movable picking saw 204 will not fall when moving. The second movable picking saw 205 is fixed on the first movable picking saw 204, and there is a gap between the two. The fixed picking saw 201 can just be inserted into the gap. The harvester grasps the movable crank 211 to rotate the rotating block 210 inside the rotating hole 209, thereby driving the first connecting rod 213 to rotate. Since the first connecting rod 213 and the second connecting rod 215 are movably connected together through the connecting shaft 214, when the first connecting rod 213 rotates, the second connecting rod 215 will be driven to move, and the movable slide 216 can only move left and right under the limiting action of the limiting slide frame 206. The movable slide 216 slides between the two rotating drums 219 at this time, but will not fall. Therefore, when harvesting water chestnuts, the harvester only needs to rotate the movable crank 211 to complete the digging of water chestnuts, which is light and labor-saving.

[0027] Example 3: Figures 1-9 As shown, the floating assembly 1 includes a floating board 101, which is used to make the water chestnut digging tool float stably on the water surface. The water chestnut harvesting assembly 2 includes a fixed picking saw 201 and a first movable picking saw 204. The top of the first movable picking saw 204 is fixedly connected to the second movable picking saw 205, and the first movable picking saw 204 and the second movable picking saw 205 cross the fixed picking saw 201 when moving. The water chestnut collecting assembly 3 includes a group of first fixed rods 301 and a group of second fixed rods 303. A group of first fixed rods 301 is fixedly installed at the bottom of the floating board 101, and a group of second fixed rods 303 are fixedly installed at the bottom of the floating board 101. A second set of fixed rods 303 are fixedly installed on the bottom of the first movable picking saw 204, a first connecting pipe sleeve 302 is fixedly connected between the bottom ends of a set of first fixed rods 301, a second connecting pipe sleeve 304 is fixedly connected between the bottom ends of a set of second fixed rods 303, the inner wall of the first connecting pipe sleeve 302 and the inner wall of the second connecting pipe sleeve 304 are rotatably connected with the mounting rod 305, both ends of the two mounting rods 305 are fixedly connected with positioning blocks 306, and a collection net bag 307 is fixedly connected between the bottoms of multiple positioning blocks 306, and the collection net bag 307 is used to collect the dug water chestnuts.

[0028] In this embodiment, when in use, the fixed picking saw 201 is stationary, the first movable picking saw 204 is movable, the first connecting pipe sleeve 302 is stationary, and the second connecting pipe sleeve 304 is movable. Then, when the first movable picking saw 204 is close to the fixed picking saw 201, the second connecting pipe sleeve 304 is away from the first connecting pipe sleeve 302, so the opening and closing of the two are opposite. Then, when the first movable picking saw 204, the second movable picking saw 205 and the fixed picking saw 201 cross-cut the ripe water chestnuts, the collecting net bag 307 is in an open state. The ripe water chestnuts are heavy and easy to sink, and the unripe water chestnuts will sink after floating briefly. After being cut, it falls directly into the collecting net bag 307, thereby preventing the ripe water chestnuts dug from sinking to the bottom of the water, and there is no need for the harvesters to free up their hands to hold the net bag to salvage them. Among them, the gravity of the collecting net bag 307 filled with water chestnuts is smaller than the buoyancy of the first hollow floating block 102 and the second hollow floating block 103, so it will not sink even if it is full. The movement of the two mounting rods 305 will drive the collecting net bag 307 to open and close. When the first movable picking saw 204, the second movable picking saw 205 and the fixed picking saw 201 are separated, the two mounting rods 305 will be close to each other, and then the collecting net bag 307 will be tightened, which can prevent the collected water chestnuts from overflowing from the collecting net bag 307 due to buoyancy.

[0029] The method of using and working principle of the present device: when in use, the whole digging tool is put into the water by holding the handle bar 104, so that the floating board 101 floats on the water surface. The first hollow floating block 102 and the two second hollow floating blocks 103 have a large enough buoyancy to make the digging tool float on the water surface. After the person who harvests the water chestnuts goes into the water, he grasps the handle bar 104 and pushes the floating board 101 forward. In the process of moving forward, he will encounter large lotus leaves and water plants. At this time, the leaf cutting blade 106 can cut the obstructing lotus leaves and water plants, thereby facilitating the floating board 101 to move forward and then move to the position of the water chestnuts. When harvesting, the first movable picking saw 204 and the second movable picking saw 205 are moved. When the stem of the water chestnut is located between the first movable picking saw 204, the second movable picking saw 205 and the fixed picking saw 201, the saw teeth of the two intersect with the saw teeth of the fixed picking saw 201, and the stem of the water chestnut is cut off when crossing, thereby completing the excavation of the water chestnut. When in use, the floating plate 101 is pushed to make the water chestnut stem located between the fixed picking saw 201 and the first movable picking saw 204 and the second movable picking saw 205, and then the floating plate 101 is pushed forward. The stem of the water chestnut will be limited by the arc surface of the limiting block 203, and at this time, the limiting sliding frame 206 is sleeved on the outside of the fixed sliding bar 208 and slides. The fixed sliding bar 208 and the limiting sliding groove 207 are interlocked, so that the first movable picking saw 204 will not fall when moving, and the second movable picking saw 204 will not fall. 05 is fixed on the first movable picking saw 204, and there is a gap between the two, and the fixed picking saw 201 can just be inserted into the gap. In this process, the harvester grasps the movable crank 211 to rotate the rotating block 210 inside the rotating hole 209, thereby driving the first connecting rod 213 to rotate. Since the first connecting rod 213 and the second connecting rod 215 are movably connected together through the connecting shaft 214, when the first connecting rod 213 rotates, the second connecting rod 215 will be driven to move, and the movable slide 216 can only move left and right under the limiting action of the limiting slide frame 206. The movable slide 216 slides between the two rotating drums 219 at this time, but will not fall. Therefore, when harvesting water chestnuts, the harvester only needs to rotate the movable crank 211 to complete the work. When harvesting water chestnuts in pairs, the fixed harvesting saw 201 is stationary, the first movable harvesting saw 204 is movable, the first connecting pipe sleeve 302 is stationary, and the second connecting pipe sleeve 304 is movable. Then, when the first movable harvesting saw 204 is close to the fixed harvesting saw 201, the second connecting pipe sleeve 304 is away from the first connecting pipe sleeve 302, so the opening and closing of the two are opposite. Then, when the first movable harvesting saw 204, the second movable harvesting saw 205 and the fixed harvesting saw 201 cross-cut the mature water chestnuts, the collecting net bag 307 is in an open state, and the weight of the mature water chestnuts will sink and fall directly into the collecting net bag 307, thereby preventing the harvested mature water chestnuts from sinking to the bottom of the water.The gravity of the collection net 307 when filled with gorgon fruit is smaller than the buoyancy of the first hollow floating block 102 and the second hollow floating block 103. Therefore, even when filled, it will not sink. The movement of the two mounting rods 305 drives the collection net 307 to open and close. When the first movable picking saw 204, the second movable picking saw 205, and the fixed picking saw 201 are separated, the two mounting rods 305 will move closer, and the collection net 307 will be tightened, which can prevent the collected gorgon fruit from overflowing the collection net 307 due to buoyancy.
