Abstract
Description
Technical Field
[0001] This utility model relates to the field of watering technology for seeding lines, and in particular to a pressureless watering device for seeding lines. Background Technology
[0002] Factory seedling production for vegetables and flowers involves several steps, including filling seedling trays with base soil, punching holes, sowing, covering with soil, and watering. Rice sowing requires filling with base soil first, then watering, then sowing, and finally covering with soil. During watering, the seedling trays pass under the water outlet of the watering device, driven by a conveyor belt. In practice, the watering volume needs to be adjusted by changing the conveyor speed of the seedling trays or the water flow rate. However, in actual production, changing the conveyor speed of the seedling trays can affect the sowing and soil covering processes on the sowing line, thus affecting the overall sowing efficiency. Adjusting the water flow rate can easily wash away the covered soil, thus affecting the seed germination rate.
[0003] To solve the above problems, a new type of pressureless watering device for seeding lines is needed. Summary of the Invention
[0004] The purpose of this invention is to provide a pressureless watering device for seeding lines, which can adjust the water volume without affecting the seedling tray conveying speed, and at the same time effectively prevent water from washing away the covered soil.
[0005] To achieve the above objectives, this utility model provides a pressureless watering device for a seeding line, including a watering bracket and a water storage tank located above the watering bracket. The bottom plate of the water storage tank is provided with a water outlet pipe. The bottom end of the water outlet pipe passes through the top plate of the watering bracket and is connected to a horizontally arranged first water pipe. The first water pipe is provided with a control valve and is connected to a horizontally arranged second water pipe. Both ends of the second water pipe are respectively connected to a horizontally arranged watering pipe through a water volume regulating valve. The watering pipe is perpendicular to the seedling tray conveying direction, and the bottom of the watering pipe is provided with water outlet holes evenly distributed along its length.
[0006] Preferably, the water storage tank has an inlet pipe at the top of its side wall, and a pressure-reducing pipe connected to the inlet pipe is provided inside the water storage tank. The diameter of the pressure-reducing pipe is larger than that of the inlet pipe.
[0007] Preferably, the pressure relief tube is equipped with a float valve.
[0008] Preferably, the water flow regulating valve is a mini ball valve.
[0009] Preferably, both the float valve and the mini ball valve are made of stainless steel.
[0010] Therefore, the present invention provides a pressureless irrigation device for a seeding line with the above-described structure, which has the following characteristics:
[0011] Beneficial effects:
[0012] 1. The water volume regulating valve can be used to adjust the water volume without changing the conveying speed of the seedling tray. The adjustment of the water volume will not affect the process of covering soil and sowing on the seed line, thus effectively ensuring the sowing efficiency.
[0013] 2. The water in the storage tank is slowed down by the buffering effect of the first water pipe, the second water pipe and the watering pipe, and flows out from the water outlet under the action of gravity, realizing pressureless watering. This effectively prevents the water from washing away the covered soil when adjusting the water volume, thus effectively ensuring the normal development of the seeds.
[0014] The technical solution of this utility model will be further described in detail below with reference to the accompanying drawings and embodiments. Attached Figure Description

[0020] The technical solution of this utility model will be further described below with reference to the accompanying drawings and embodiments.
[0021] Example
[0022] like Figure 1-3As shown, a pressureless watering device for a seeding line includes a watering bracket 1 and a water storage tank 2 located above the watering bracket 1. A water outlet pipe 3 is provided on the bottom plate of the water storage tank 2. The bottom end of the water outlet pipe 3 passes through the top plate of the watering bracket 1 and connects to a horizontally arranged first water pipe 4. A control valve 5 is provided on the first water pipe 4 to control whether the entire watering device discharges water. The first water pipe 4 is connected to a horizontally arranged second water pipe 6. Both ends of the second water pipe 6 are connected to a horizontally arranged watering pipe 7 via a water flow regulating valve 9. The water flow regulating valve 9 is made of stainless steel and is a mini ball valve used to regulate the water flow. The watering pipe 7 is perpendicular to the seedling tray conveying direction, and the bottom of the watering pipe 7 has water outlet holes 8 evenly distributed along its length.
[0023] A water inlet pipe 10 is installed on the top side wall of the water storage tank 2. A pressure-reducing pipe 11, connected to the water inlet pipe 10, is installed inside the water storage tank 2. The diameter of the pressure-reducing pipe 11 is larger than that of the water inlet pipe 10. The pressure-reducing pipe 11 is used to reduce water pressure, preventing turbulence and splashing in the water storage tank 2 due to excessive water pressure. A float valve 12 is installed on the pressure-reducing pipe 11. The float valve 12 is made of stainless steel, which is rust-resistant and durable. The float valve 12 is used to automatically control the liquid level in the water tower or pool. It features simple maintenance, flexibility, durability, high accuracy in liquid level control, and water level unaffected by water pressure, as well as a tight, leak-proof opening and closing mechanism.
[0024] During use, the water in the storage tank is slowed down by the buffering effect of the first water pipe, the second water pipe, and the irrigation pipe, and flows out from the outlet under the action of gravity, realizing pressureless irrigation. This effectively prevents the water from washing away the covered soil when adjusting the irrigation amount, thus effectively ensuring the normal development of the seeds. The water flow regulating valve 9 can change the water flow of the outlet 8, realizing the adjustment of the irrigation amount without changing the conveying speed of the seedling tray. The adjustment of the irrigation amount will not affect the soil covering and sowing procedures on the sowing line, effectively ensuring the sowing efficiency.
[0025] Therefore, the present invention provides a pressureless watering device for a seeding line with the above-mentioned structure, which can adjust the watering volume without affecting the seedling tray conveying speed, and can effectively prevent water from washing away the covered soil.
[0026] Finally, it should be noted that the above embodiments are only used to illustrate the technical solution of this utility model and not to limit it. Although the utility model has been described in detail with reference to preferred embodiments, those skilled in the art should understand that modifications or equivalent substitutions can still be made to the technical solution of this utility model, and these modifications or equivalent substitutions cannot cause the modified technical solution to deviate from the spirit and scope of the technical solution of this utility model.
