Abstract
Description
Technical Field
[0001] This utility model relates to the field of water chestnut harvesting technology, specifically a water chestnut harvesting device. Background Technology
[0002] Euryale ferox, or water caltrop, is an annual aquatic herb belonging to the genus Euryale in the family Nymphaeaceae. It typically grows in ponds and lakes. Its leaves are green and wrinkled on the upper surface, and purplish-red on the underside, densely covered with short hairs. The flowers are solitary with purplish-red petals. The fruit is a berry, spherical, covered with hard spines, resembling a chicken's head, hence its other name, "chicken head rice." The seeds are edible, rich in starch, protein, vitamins, and other nutrients. They are commonly used in cooking and also have medicinal uses, including strengthening the spleen, stopping diarrhea, and tonifying the kidneys and securing essence. It has wide applications in the food and pharmaceutical fields.
[0003] Currently, the main methods for harvesting water chestnuts are manual harvesting and mechanical harvesting. Manual harvesting requires growers to work arduously in knee-deep water in water chestnut fields, wearing waterproof trousers. Because water chestnuts are thorny, hand harvesting is not only inefficient but also extremely dangerous, as it easily leads to injuries. Prolonged exposure to damp conditions also harms the body. Furthermore, it's difficult to accurately judge fruit ripeness manually, leading to delayed or over-harvesting, affecting yield and fruit quality. While mechanical harvesting equipment can improve efficiency to some extent, its high cost deters many small-scale growers. Moreover, in shallow water areas or complex water bodies with dense aquatic plants, the equipment's flexibility is greatly reduced, making it prone to damage, and maintenance costs are high and require specialized personnel. Utility Model Content
[0004] The purpose of this invention is to provide a water chestnut harvesting device to solve the problems mentioned in the background art.
[0005] To achieve the above objectives, this utility model provides the following technical solution: a water chestnut harvesting device, including a handle, a picking mechanism at the top of the handle, and a stem-breaking mechanism at the rear of the picking mechanism.
[0006] The picking mechanism includes a picking component and a locking component. The picking component is located on the top of the handle, and the locking component is located on the surface of the picking component.
[0007] The stem-breaking mechanism includes a disassembly assembly and a cutting assembly. The disassembly assembly is located behind the harvesting assembly, and the cutting assembly is located inside the disassembly assembly.
[0008] Preferably, the picking component includes a protruding rod, which is fixedly connected to the top of the handle, and a positioning spoon is fixedly connected to the top of the protruding rod.
[0009] Preferably, the positioning component includes a root and stem groove and a drain hole, wherein the root and stem groove is located inside the left side of the positioning spoon, and the drain hole is located inside the surface of the positioning spoon.
[0010] Preferably, the disassembly and assembly assembly includes a mounting base, which is fixedly connected to the rear side of the positioning spoon. A locking block is engaged inside the rear side of the mounting base, and a locking strip is engaged inside the outer ring of the locking block. The locking strip is fixedly connected to the inner ring of the mounting base, and a bolt is sleeved on the inner ring of the locking block. The bolt is threadedly connected to the mounting base.
[0011] Preferably, the cutting assembly includes a U-shaped cutting blade, which is fixedly connected to the inner ring of the locking block. The opening direction of the locking block is consistent with the root and stem locking groove. A clearance hole is provided on the front side of the U-shaped cutting blade, which is located inside the rear side of the positioning spoon.
[0012] Compared with the prior art, the present invention provides a harvesting device for water chestnuts, which has the following beneficial effects:
[0013] 1. This water chestnut harvesting device, through its ingeniously designed harvesting mechanism, greatly simplifies the harvesting process. Workers simply need to grip the handle to easily move the positioning spoon quickly beneath the water chestnut fruit. With the precise cooperation of the rootstock groove and the empty hole, the water chestnut rootstock is quickly secured. Then, a gentle swing of the handle allows the U-shaped cutting blade to efficiently sever the rootstock, allowing the water chestnut fruit to detach smoothly. This process is simple and seamless, significantly reducing the time required to harvest individual water chestnuts compared to traditional manual harvesting, greatly improving overall harvesting efficiency. It enables the harvesting of large areas of water chestnuts in a shorter time, significantly enhancing harvesting efficiency.
[0014] 2. This water chestnut harvesting device completely changes the traditional manual harvesting method. Growers previously had to immerse themselves in cold, damp water for extended periods, putting immense strain on their bodies and frequently resulting in injuries from the water chestnut thorns. This device allows workers to harvest the fruit from the edge of the field or on a boat, simply by holding a handle, eliminating the need to go into the water and effectively preventing the harmful effects of moisture. Furthermore, harvesting using this device eliminates direct contact with the thorny water chestnuts, fundamentally preventing injuries and significantly improving working conditions, reducing labor intensity, and effectively lowering the risk of injury.
[0015] 3. For small-scale growers, the high cost of mechanical harvesting equipment is prohibitive. This water chestnut harvesting device, however, is inexpensive, consisting of only a simple handheld tool, making it economical and easily meeting their harvesting needs. In terms of aquatic environments, whether in shallow water or areas with dense aquatic plants, workers can easily maneuver the handle to accurately position the positioning spoon to the water chestnut fruit, demonstrating excellent environmental adaptability despite limitations in aquatic conditions. This overcomes the shortcomings of large machinery in complex aquatic operations and is highly adaptable to different planting scales and aquatic environments.
[0016] 4. In practical use, ease of maintenance is crucial for this water chestnut harvesting device. The stem-cutting mechanism of this device fully considers this, with the U-shaped cutting blade fixed to the rear of the mounting base via a unique disassembly and assembly assembly. If the operator needs to replace the U-shaped cutting blade, simply rotating the bolts allows for quick disassembly and installation of the clamping block. The operation is simple and easy to understand, requiring no professional technical knowledge, greatly saving maintenance time and costs, ensuring the device is always in good working order, and continuously and efficiently serving the water chestnut harvesting work. This convenient maintenance and replacement design ensures easy maintenance and replacement. Attached Figure Description

Those skilled in the art can understand the specific meaning of the above terms in this utility model according to the specific circumstances.
[0025] This utility model provides a technical solution:
[0026] Example 1
[0027] Combination Figures 1 to 4 A harvesting device for water chestnut includes a handle 3, a harvesting mechanism 1 is provided on the top of the handle 3, and a stem-breaking mechanism 2 is provided on the rear side of the harvesting mechanism 1.
[0028] The picking mechanism 1 includes a picking component 11 and a locking component 12. The picking component 11 is located on the top of the handle 3, and the locking component 12 is located on the surface of the picking component 11.
[0029] The harvesting component 11 includes a protruding rod 1101, which is fixedly connected to the top of the handle 3. A positioning spoon 1102 is fixedly connected to the top of the protruding rod 1101. The positioning component 12 includes a root and stem slot 1201 and a hole 1202. The root and stem slot 1201 is opened inside the left side of the positioning spoon 1102, and the hole 1202 is opened inside the surface of the positioning spoon 1102.
[0030] Furthermore, staff only need to hold the handle 3 to control the movement of the positioning spoon 1102, so that the root below the gorgon fruit is engaged in the inner ring of the empty hole 2202 through the root slot 1201. Then, simply pull the handle 3 to cut the gorgon fruit root through the U-shaped cutting blade 2201. After that, staff can harvest the gorgon fruit through the positioning spoon 1102. The setting of the hole 1202 prevents water from accumulating in the positioning spoon 1102, making it convenient for staff to use.
[0031] Example 2
[0032] See Figures 1 to 4 Furthermore, based on Embodiment 1, the stem-breaking mechanism 2 includes a disassembly and assembly component 21 and a cutting component 22. The disassembly and assembly component 21 is located on the rear side of the harvesting component 11, and the cutting component 22 is located inside the disassembly and assembly component 21.
[0033] The assembly / disassembly component 21 includes a mounting base 2101, which is fixedly connected to the rear side of the positioning spoon 1102. A locking block 2102 is engaged inside the rear side of the mounting base 2101. A locking strip 2103 is engaged inside the outer ring of the locking block 2102. The locking strip 2103 is fixedly connected to the inner ring of the mounting base 2101. A bolt 2104 is sleeved on the inner ring of the locking block 2102. The bolt 2104 is threaded into the mounting base 2101. The cutting component 22 includes a U-shaped cutting blade 2201, which is fixedly connected to the inner ring of the locking block 2102. The opening direction of the locking block 2102 is consistent with the root and stem slot 1201. A clearance hole 2202 is opened on the front side of the U-shaped cutting blade 2201, which is located inside the rear side of the positioning spoon 1102.
[0034] Furthermore, the U-shaped cutting blade 2201 is fixedly connected to the rear side of the mounting base 2101, so that the water chestnut root that is locked in the root slot 1201 can be cut by simply shaking it slightly in the empty hole 2202. The operation is simple and easy to use. At the same time, the staff can also complete the disassembly and assembly of the locking block 2102 by simply rotating the bolt 2104, which makes it easy for the staff to replace the U-shaped cutting blade 2201. The operation is simple and easy for the staff to use.
[0035] In actual operation, when this device is used, the staff only needs to hold the handle 3 to control the positioning spoon 1102 to move it below the water chestnut fruit, so that the root of the water chestnut fruit is engaged in the empty hole 2202 through the root slot 1201. Then the staff swings the handle 3 to make the positioning spoon 1102 shake. The shaking of the positioning spoon 1102 causes the U-shaped cutting blade 2201 to shake. The shaking of the U-shaped cutting blade 2201 contacts the root and cuts the root. After that, the water chestnut fruit is separated from the root and stem. Then the staff can control the positioning spoon 1102 to enter the storage container to complete the harvesting of the water chestnut fruit.
[0036] When the U-shaped cutting blade 2201 needs to be replaced, the worker first rotates the bolt 2104. Rotating the bolt 2104 disengages it from the locking block 2102 and the mounting base 2101. Then, the worker moves the locking block 2102 backward, which disengages it from the mounting base 2101. This completes the disassembly of the locking block 2102. The worker then inserts the new locking block 2102 into the rear side of the mounting base 2101. After the locking block 2102 is fully inserted into the rear side of the mounting base 2101, the worker inserts the bolt 2104 into the locking block 2102 and rotates it. The bolt 2104 rotates and moves forward from the rear side of the mounting base 2101 until it can no longer be rotated. This completes the installation of the locking block 2102 and the replacement of the U-shaped cutting blade 2201.
