Description

Technical Field

[0001] The utility model belongs to the technical field of field tobacco planting, and in particular relates to a combined drip irrigation belt. Background Art

[0002] At present, drip irrigation has been widely used in field tobacco planting. It mainly adopts a PE pipe structure with holes in the pipe body and lays it on the tobacco ridge. When water supply is needed, water is directly supplied to the PE pipe, and the water source can be sprayed from the holes of the PE pipe and supply water to the tobacco plants. The overall use effect is good. However, there are also some problems in the actual application process: 1) The PE pipe has a strong integrity. One PE pipe corresponds to one tobacco ridge or even several tobacco ridges. However, the tobacco growth process involves multiple mechanical tillage, weeding and soiling operations, which can easily cause the PE pipe to be crushed, deformed or broken. Either the entire PE pipe is scrapped, or it needs to be cut and hot-melt welded to patch the pipe, which not only requires professional treatment, but also causes the pipe diameter at the joint to narrow; 2) Due to the uncertainty of the opening position and the water hammer effect, the PE pipe moves, and it is impossible to accurately supply water to the tobacco plants. The height of the tobacco ridge is relatively large, which easily causes the water supplied by drip irrigation to flow between the ridges in the later stage, resulting in water waste. Especially when using integrated water and fertilizer topdressing, it will cause waste of water and fertilizer. Utility Model Content

[0003] In view of the shortcomings of the prior art, the purpose of the utility model is to provide a combined drip irrigation belt. The utility model improves the existing drip irrigation belt, has a simple overall structure and is convenient to assemble, disassemble and maintain, and can effectively position the tobacco plants and supply water and fertilizer.

[0004] In order to achieve the above purpose, the utility model provides the following technical solutions:

[0005] A combined drip irrigation belt, which includes branch units arranged corresponding to tobacco plants, several conveyor belts connecting two adjacent branch units, and a head for sealing the branch unit at the end. The branch unit includes a tee, two coaxial joints of the tee are in the shape of cones, and a telescopic hose made of plastic is connected to the end of the vertical joint. The end of the telescopic hose is closed and a row of axially arranged drip irrigation holes is opened on the tube body.

[0006] Preferably, an L-shaped winding column is provided on the outer wall of the vertical joint of the three-way pipe, and a pull wire is integrally provided at the end of the telescopic hose.

[0007] Preferably, the coaxial joint of the tee pipe is integrally provided with two sealing gaskets on the outer wall of the cone-shaped maximum outer diameter.

[0008] Preferably, the conveyor belt is a PE pipe.

[0009] Preferably, the inner wall of the coaxial joint of the tee pipe used to connect to the next conveyor belt is provided with an internal thread, and the end cap is a cylinder and the outer wall is provided with an external thread for screwing into the internal thread.

[0010] The application process of this utility model is as follows:

[0011] First of all, the laying method of the PE pipe drip irrigation belt in the utility model is different from that in the prior art. The utility model can determine the length of each section of the conveyor belt according to the spacing between tobacco plants on the ridge (modern tobacco planting has specific requirements for the spacing between tobacco plants and the row spacing, so the spacing between tobacco plants is basically fixed), and then the two ends of each section of the conveyor belt are respectively connected with the coaxial joints of two three-way pipes (two sealing gaskets can effectively ensure the airtightness of the connection), so as to complete the connection of multiple conveyor belts and three-way pipes to form a drip irrigation belt, and at the same time, each three-way pipe is arranged corresponding to a tobacco plant and the free coaxial joint of the three-way pipe at the end of the drip irrigation belt is connected to the head, so as to complete the closure of the end of the drip irrigation belt.

[0012] During the above assembly process, the telescopic hose at the vertical joint of the three-way pipe is extended from a pleated straight tube state to an arc tube shape surrounding the tobacco plant (the tobacco seedling in the early stage), and the drip irrigation hole needs to be kept upward and the water outlet direction is toward the tobacco plant (the tobacco seedling in the early stage). At the same time, the pull wire is coiled on the L-shaped winding column to prevent the water hammer effect during the later water flow from causing the telescopic hose to be displaced or deformed.

[0013] Finally, the head ends of several drip irrigation belts are connected to the water source output by the water pump. The water source (or liquid fertilizer) is dripped to the roots of the tobacco plants through the drip irrigation holes on each telescopic hose to improve the water and fertilizer supply effect. At the same time, if a conveyor belt is damaged, it can be quickly replaced with a spare conveyor belt to complete the repair, and the three-way pipe can be used for a long time and repeatedly.

[0014] Compared with the prior art, the utility model has the following advantages: the utility model improves the existing drip irrigation belt, has a simple overall structure and is convenient to assemble, disassemble and maintain, and can effectively position the tobacco plants for water and fertilizer supply.

[0018] In order to make the purpose, technical solution and advantages of the utility model more clear, the utility model is further described in detail below in conjunction with the accompanying drawings and embodiments. It should be understood that the specific embodiments described here are only used to explain the utility model and are not used to limit the utility model.

[0019] like Figure 1-3 As shown, a combined drip irrigation belt comprises branch units arranged corresponding to tobacco plants, a plurality of conveyor belts 1 connecting two adjacent branch units, and a sealing head 5 for sealing the last branch unit:

[0020] The branch unit includes a tee 2, the two coaxial joints 21 of the tee 2 are in the shape of a cone, and the outer wall of the coaxial joint 21 at the maximum outer diameter of the cone is integrally provided with two sealing gaskets 22. The inner wall of the coaxial joint 21 of the tee 2 used to connect the next conveyor belt 1 is provided with an internal thread, and the head 5 is a cylinder and the outer wall is provided with an external thread for screwing the internal thread.

[0021] The end of the vertical joint 23 of the three-way pipe 2 is connected to a telescopic hose 3 made of plastic material. The end of the telescopic hose 3 is closed and a row of axially arranged drip irrigation holes 31 are opened on the tube body. The outer wall of the vertical joint of the three-way pipe 2 is provided with an L-shaped winding column 24. The end of the telescopic hose 3 is integrally provided with a pull wire 4 for winding around the L-shaped winding column. The conveyor belt 1 is a PE pipe.

[0022] The application process of this utility model is as follows:

[0023] First of all, the laying method of the PE pipe drip irrigation belt in the utility model is different from that in the prior art. The utility model can determine the belt length of each section of the conveyor belt 1 according to the spacing between tobacco plants on the ridge (modern tobacco planting has specific requirements for the spacing between tobacco plants and the row spacing, so the spacing between tobacco plants is basically fixed), and then the two ends of each section of the conveyor belt 1 are respectively connected with the coaxial joints 21 of two three-way pipes 2 (two sealing gaskets 22 can effectively ensure the airtightness of the connection), so that the connection of multiple conveyor belts 1 and three-way pipes 2 is completed to form a drip irrigation belt. At the same time, each three-way pipe 2 is arranged corresponding to a tobacco plant and the free coaxial joint 21 of the three-way pipe 2 at the end of the drip irrigation belt is connected to the head 5, so that the end of the drip irrigation belt is closed.

[0024] In the above assembly process, the telescopic hose 3 at the vertical joint 23 of the three-way pipe is extended from the folded straight tube state to the arc tube shape surrounding the tobacco plant (the tobacco seedling in the early stage), and the drip irrigation hole 31 needs to be kept upward and the water outlet direction is toward the tobacco plant (the tobacco seedling in the early stage). At the same time, the pull wire 4 is coiled on the L-shaped winding column 24 to prevent the water hammer effect during the later water flow from causing the telescopic hose 3 to be displaced or deformed.

[0025] Finally, the head ends of the plurality of drip irrigation belts are connected to the water source output by the water pump, and the water source (or liquid fertilizer) is dripped to the root and stem of the tobacco plant through the drip irrigation holes 31 on each telescopic hose, thereby improving the water supply and fertilizer supply effect. At the same time, if a conveyor belt is damaged at a certain place, the spare conveyor belt 1 can be quickly replaced to complete the repair, and the three-way pipe 2 can be used for a long time and repeatedly.
