Description

Technical Field

[0001] This utility model relates to the field of agricultural weeding equipment technology, and in particular to a heat-insulating blanket for weeding with hot water. Background Technology

[0002] Currently, hot water weeding, as an environmentally friendly method, is gradually gaining popularity in households, gardening, and agriculture. Traditional hot water weeding methods mainly involve directly spraying hot water with a handheld water gun or a fixed nozzle, using high temperatures to destroy the plant cell structure and achieve the purpose of weeding. However, this method suffers from problems such as rapid heat loss and low thermal efficiency, and manually operating the water gun is not only labor-intensive but also makes it difficult to achieve uniform hot water coverage.

[0003] In the existing technology, in order to solve the problem of heat loss in hot water weeding, some improved hot water weeding equipment has appeared on the market, such as sprinkler irrigation systems with insulation layers. These sprinkler irrigation systems usually increase the number of nozzles to expand the coverage area of ​​the spray and wrap the sprinkler pipes with insulation material. However, this method, by increasing the number of nozzles and wrapping the pipes with insulation material, still cannot solve the problem of the rapid cooling of the hot water sprayed from the nozzles and the heat loss at the nozzle connection.

[0004] Regarding the aforementioned technologies, the inventors believe that current hot water weeding methods suffer from the drawback of rapid heat loss during the process. Utility Model Content

[0005] To address the issue of rapid heat loss during hot water weeding, this application provides a heat-insulating blanket for hot water weeding.

[0006] The present application provides a heat insulation blanket for weed control using hot water, which includes a silicone blanket, a nozzle head, a connecting pipe and a hot water pipe connector. The nozzle head is connected and fixed to the silicone blanket, the connecting pipe connects the nozzle head, one end of the hot water pipe connector is interference-fitted to the connecting pipe, and the other end is connected to an external hot water source; The silicone blanket has a positioning pin at its edge, and the silicone blanket also has a positioning hole at its edge for the positioning pin on the adjacent silicone blanket to be inserted and positioned.

[0007] By adopting the above technical solution, the hot water pipe is preferably made of flexible insulation material. A connecting pipe continuously and rapidly delivers hot water to the nozzle head, while the connecting pipe is interference-fitted to the hot water pipe joint to ensure the airtightness of the hot water source transmission, further reducing heat loss during hot water transmission. Hot water circulates from the bottom of the silicone blanket, which, due to its inherent properties, provides continuous temperature insulation, achieving the effect of hot water weed control. The positioning pins and holes on the edge of the silicone blanket form a modular splicing structure, facilitating rapid assembly when laying the silicone blanket over large areas. The interlocking positioning prevents displacement, improving the overall airtightness and insulation performance of the insulation blanket. The nozzle head is connected and fixed to the silicone blanket for uniformly spraying hot water to enhance the weed control effect. This solution solves the problems of rapid heat loss and low installation efficiency in traditional weed control and insulation devices.

[0008] Optionally, the silicone blanket is rectangular in shape, with positioning pins at the edges of adjacent sides and positioning holes at the other two edges.

[0009] By adopting the above technical solution, the silicone blanket has positioning pins at any two adjacent edges, and positioning holes at the remaining two edges, forming an interlocking structure. During installation, adjacent insulation blankets fit together through the positioning pins and positioning holes, forming a grid-like splicing, effectively reducing splicing gaps and preventing heat loss; at the same time, the grid-like splicing improves the installation efficiency of the insulation blanket, saves installation time, and further expands the applicability of the insulation blanket.

[0010] Optionally, the positioning pin includes a fixing section and a plug-in section; wherein the fixing section is integrally formed with the silicone blanket and is cylindrical, the plug-in section is connected to the fixing section and is conical, and the maximum diameter of the plug-in section is larger than the diameter of the positioning hole.

[0011] By adopting the above technical solution, the fixing section and the silicone blanket are integrally injection molded, ensuring the connection strength between the silicone blankets. The insertion section adopts a tapered head structure, with its maximum diameter slightly larger than the positioning hole diameter. During insertion, the elastic deformation of the silicone itself achieves a tight fit. The tapered design guides the insertion section to automatically align, reducing installation difficulty. At the same time, the radial pressure generated by the interference fit enhances the sealing performance and prevents hot water leakage, thus improving the reliability of the insulation blanket and the ease of installation.

[0012] Optionally, the nozzle head is connected to the silicone blanket by a bolt with a washer; the silicone blanket also has a mounting hole, and the bolt passes through the mounting hole and is threaded to the nozzle head.

[0013] By adopting the above technical solution, the bolt with a gasket can disperse the bolt pressure through the gasket, preventing the silicone blanket from tearing; furthermore, the gasket can compensate for the gap between the bolt and the mounting hole, thus avoiding the risk of low insulation efficiency of the silicone blanket at the mounting hole. The threaded connection facilitates the disassembly of the nozzle head, thereby facilitating the maintenance or replacement of the nozzle head.

[0014] Optionally, the nozzle head is provided with a connecting seat for bolt connection at the upper end, one or more plug-in posts for interference connection of the connecting pipe at the side end, a water spray nozzle communicating with the plug-in post at the lower end, and a support seat for supporting the nozzle head away from the ground at the lower end.

[0015] By adopting the above technical solution, the connecting seat provides an installation surface for the connection between the bolt and the nozzle head. The side-end insertion post and the connecting pipe are interference-fitted to ensure a sealed fluid passage. The lower water nozzle can achieve rapid, large-area hot water spraying through modular quick assembly of the nozzle head. The support base lifts the nozzle head off the ground, which can prevent the water nozzle from being blocked by ground mud, and at the same time facilitate the diffusion of the hot water sprayed from the water nozzle to achieve rapid, large-area hot water spraying.

[0016] Optionally, the support base is integrally formed with the nozzle head and located on the outer periphery of the water spray nozzle, and a guide groove is formed between any two adjacent support bases.

[0017] By adopting the above technical solution, the integrally molded support base is distributed around the water nozzle to form a ring support structure, which enhances the pressure resistance of the nozzle head. The guide groove between adjacent support bases guides the water flow along a preset path to prevent water flow deviation from causing local overheating or uneven weeding, thereby improving weeding efficiency.

[0018] Optionally, the plug-in post has a pagoda-shaped connection structure, the plug-in post includes multiple tapered tubes, and an annular sealing groove is formed at the connection of any two tapered tubes; the plug-in post is interference-fitted with the connecting tube.

[0019] By adopting the above technical solution, multiple tapered tubes are coaxially integrated, with their diameter decreasing from the inside to the outside, forming a tapered interface. When the connecting tube and the plug are interlocked, the outer tapered tube of the plug compresses the connecting tube to form a structure similar to a sealing ring, while the annular sealing groove directly fits into the inner wall of the connecting tube. Therefore, the tapered tube and the annular sealing groove work together to form a double sealing barrier, enhancing the sealing performance of the connecting tube and the plug. This structure allows for quick assembly and disassembly of the connecting tube and the plug, while ensuring long-term stability.

[0020] Optionally, one end of the hot water pipe connector is a plug-in post and the other end is a threaded pipe; the plug-in post is interference-fitted to one end of the connecting pipe, and the threaded pipe is threadedly connected to the outlet pipe of the external hot water source.

[0021] By adopting the above technical solution, the plug-in post and the connecting pipe are interference-fitted, and the threaded pipe is threadedly connected to the outlet pipe of the external hot water pipe, realizing the rapid connection between the insulation blanket and the hot water source. The coaxial design of the plug-in post and the threaded pipe ensures the straightness of the fluid channel and reduces the direct pressure during fluid flow; furthermore, this structure can achieve rapid insertion and transmission of hot water, thereby reducing heat loss during the hot water transmission process.

[0022] In summary, this application includes at least one of the following beneficial technical effects: 1. During installation, the interference fit between the positioning pins and positioning holes on the edge of the silicone blanket enables rapid splicing and fixing between the silicone blankets, thus forming a grid-like splicing structure. This effectively reduces splicing gaps, improves the insulation efficiency of the silicone blanket, and because the silicone material itself has elastic deformation capabilities, a self-sealing effect can be formed at the joints of the silicone blanket, preventing hot water leakage and improving the practicality of the silicone blanket. 2. The pagoda-shaped insertion post of the nozzle head, through its own tapered tube and annular sealing groove, improves the sealing performance of the connection when the connecting pipe is interference-fitted, and ensures the long-term stability of the connection. The support base at the bottom of the nozzle head can raise the distance between the nozzle head and the ground, preventing the water nozzle from being blocked by surface mud and debris during long-term use. At the same time, the guide groove between the support bases can guide and diffuse the hot water spray path, improve the hot water spray effect, and thus improve the efficiency of hot water weeding. 3. The nozzle head and the silicone blanket are connected by bolts with washers. The washers can compensate for the gaps in the bolt connection, preventing hot water leakage and further improving the effect of hot water weeding. At the same time, the bolt connection also allows for quick connection and replacement of the nozzle head and the silicone blanket, improving the convenience and operability of the insulation system.

[0030] This application discloses a heat-insulating blanket for weed control using hot water. (See also...) Figure 1 A hot water weeding insulation blanket includes a silicone blanket 1, a nozzle head 2, a connecting pipe 3, and a hot water pipe connector 4. The components work together to form a hot water weeding insulation blanket that can be quickly assembled and disassembled and has high heat preservation efficiency.

[0031] Reference Figure 1 , Figure 2 As shown, the silicone blanket 1 is preferably made of liquid silicone material and is integrally molded, and preferably has a sheet-like rectangular structure. Positioning pins 5 and positioning holes 6 are provided at the edges of its adjacent sides. The positioning pins 5 and silicone blanket 1 are integrally injection molded. The positioning pins 5 are divided into a fixing section 7 and an insertion section 8.

Furthermore, the maximum diameter of the insertion section 8 is slightly larger than the diameter of the positioning hole 6. During installation, adjacent silicone blankets 1 can be seamlessly joined by interference fit between the positioning pins 5 and the positioning holes 6.

[0032] Reference Figure 3 As shown, the silicone blanket 1 is also provided with a mounting hole 9. The silicone blanket 1 and the nozzle head 2 are connected to each other by a bolt 11 with a washer 10 fixed in the mounting hole 9. The nozzle head 2 is also provided with a connecting seat 12, which allows the bolt 11 to be threadedly connected to the nozzle head 2 after passing through the mounting hole 9. The connecting seat 12 is integrally formed with the nozzle head 2, and the outer diameter of the connecting seat 12 is preferably slightly smaller than the inner diameter of the mounting hole 9. When connecting the nozzle head 2 and the silicone blanket 1, the connecting seat 12 can be inserted into the mounting hole 9 first, and then the bolt 11 can be used for connection, thereby further improving the reliability of the connection between the silicone blanket 1 and the nozzle head 2.

[0033] Reference Figure 4 , Figure 5As shown, the nozzle head 2 also includes a plug-in post 13 located at the side end, a water nozzle 14 at the lower end, and a support base 15 that supports the nozzle head 2 away from the ground.
