Description

Technical Field

[0001] This utility model relates to the field of agricultural equipment technology, specifically to a drip irrigation device for crops with easily adjustable flow rate. Background Technology

[0002] Drip irrigation systems for crops are a highly efficient water-saving irrigation system that uses a pipeline system to deliver water to the vicinity of crop roots and then slowly drips the water into the soil through drippers to meet the crop's growth needs.

[0003] Existing drip irrigation systems for crops use drip emitters on drip irrigation pipes to irrigate crops. These systems consist of multiple drip irrigation pipes, each corresponding to different areas of crops. When different crops are grown in different areas, the drip flow rate needs to be adjusted accordingly. However, most drip irrigation systems require replacing the drip emitters on the drip irrigation pipes to change the flow rate, which is time-consuming, labor-intensive, and may affect irrigation efficiency. Therefore, we propose a crop drip irrigation system with easily adjustable flow rates to effectively address these drawbacks. Utility Model Content

[0004] The purpose of this invention is to provide a drip irrigation device for crops with easily adjustable flow rate, in order to solve the problems mentioned in the background art.

[0005] This utility model is achieved through the following technical solution: a drip irrigation device for crops with easily adjustable flow rate, comprising a water supply pipe, a plurality of drip irrigation pipes on the water supply pipe, a plurality of transition pipes fixedly provided on the water supply pipe, the plurality of transition pipes being arranged radially through the water supply pipe, the plurality of transition pipes and the plurality of drip irrigation pipes being arranged in a one-to-one correspondence, the drip irrigation pipes being connected to the inner cavity of the transition pipes, each of the plurality of transition pipes having a water inlet hole through the side wall of the inner cavity of the water supply pipe, and a piston being slidably provided inside each of the plurality of transition pipes along the length direction of the transition pipe, the width of the piston being not less than the diameter of the water inlet hole.

[0006] Optionally, the end of the transition tube away from the drip irrigation tube has a top cover, and a drive rod is fixedly provided on the side of the piston facing the top cover. One end of the drive rod extends to the outside of the transition tube, and the drive rod is slidably connected to the top cover along the length of the transition tube.

[0007] Optionally, a wide plate is provided on the side of the water supply pipe away from the drip irrigation pipe. The wide plate is slidably arranged along the length direction of the transition pipe, and several drive rods are connected to the wide plate.

[0008] Optionally, one end of one or more of the drive rods slides through the wide plate along the length of the transition tube, and the drive rods and the wide plate are detachably connected.

[0009] Optionally, a plurality of fixing pins are slidably provided on the wide plate along the height direction of the wide plate, and the plurality of fixing pins and the plurality of driving rods are arranged in a one-to-one correspondence, and the driving rods are provided with limiting holes for the fixing pins to be inserted.

[0010] Compared with the prior art, this utility model provides a drip irrigation device for crops with easily adjustable flow rate, which has the following beneficial effects:

[0011] This invention connects the drip irrigation pipe to the inner cavity of the water supply pipe through a transition pipe. A water inlet hole for water supply is opened on the transition pipe. The size of the water inlet hole is adjusted by a sliding piston inside the transition pipe, thereby changing the drip flow rate of all drippers on a single pipe without the need to replace the drippers, making flow rate adjustment more convenient and quick. Furthermore, the sliding of the wide plate allows all pistons to move together, thereby directly adjusting the flow rate of all drip irrigation pipes, enabling users to change the flow rate adjustment method according to different drip irrigation needs.

[0017] The technical solutions of the present utility model will be clearly and completely described below with reference to the accompanying drawings of the embodiments. Obviously, the described embodiments are only some embodiments of the present utility model, and not all embodiments. Based on the embodiments of the present utility model, all other embodiments obtained by those of ordinary skill in the art without creative effort are within the protection scope of the present utility model.

[0018] Please see Figure 1 - Figure 4A drip irrigation device for crops with easily adjustable flow rate includes a water supply pipe 1, several drip irrigation pipes 2 on the water supply pipe 1, and several transition pipes 3 fixedly installed on the water supply pipe 1. The transition pipes 3 are arranged radially through the water supply pipe 1, and the transition pipes 3 and the drip irrigation pipes 2 are arranged in a one-to-one correspondence. The drip irrigation pipes 2 are connected to the inner cavity of the transition pipes 3. Each of the transition pipes 3 has a water inlet hole 301 through it on the side wall of the inner cavity of the water supply pipe 1. In reality, the length of the drip irrigation pipes 2 is usually long, and the drip irrigation pipes 2 are usually flexible. Therefore, if the dripper is adjusted on the drip irrigation pipe 2, it will take a lot of time and greatly affect the efficiency of drip irrigation. Therefore, by connecting the water supply pipe 1 and the drip irrigation pipes 2 through the transition pipes 3 with higher hardness, the drip irrigation flow rate in the drip irrigation pipe 2 can be changed by changing the size of the water inlet hole 301.

[0019] Specifically, pistons 4 are slidably installed in several transition pipes 3 along the length of the transition pipe 3. The width of the pistons 4 is not less than the diameter of the water inlet 301, so that the user can control the pistons 4 to slide in the transition pipe 3, thereby changing the area of ​​the pistons 4 blocking the water inlet 301, and thus changing the opening degree of the water inlet 301, thereby adjusting the drip irrigation flow rate. This allows the user to adjust the drip irrigation flow rate in different drip irrigation pipes 2 according to their needs when drip irrigating different crops.

[0020] Furthermore, the end of the transition tube 3 away from the drip irrigation tube 2 has a top cover, and the piston 4 is fixedly provided with a drive rod 401 on the side facing the top cover. One end of the drive rod 401 extends to the outside of the transition tube 3, and the drive rod 401 is slidably connected to the top cover along the length of the transition tube 3, so that the user can control the piston 4 by pushing and pulling the drive rod 401 on the outside of the transition tube 3, thereby making the movement control of the piston 4 more convenient and faster.

[0021] When all drip irrigation pipes 2 are used to drip irrigate the same type of crop, it is necessary to control all pistons 4 at the same time to make the flow rate adjustment more convenient. Therefore, in this application, a wide plate 5 is provided on the side of the water supply pipe 1 away from the drip irrigation pipe 2. The wide plate 5 is slidably arranged along the length direction of the transition pipe 3. Several drive rods 401 are connected to the wide plate 5 together, so that the user can control the movement of the wide plate 5 to control the movement of several drive rods 401, thereby achieving the purpose of simultaneously controlling the movement of several pistons 4.

[0022] Furthermore, one end of several drive rods 401 slides through the wide plate 5 along the length of the transition tube 3. The drive rods 401 and the wide plate 5 are detachably connected so that when the drive rods 401 and the wide plate 5 are movably connected, several drive rods 401 can move independently on the wide plate 5 to achieve the purpose of individually controlling the movement of the corresponding piston 4. When several drive rods 401 are all fixedly connected to the wide plate 5, the wide plate 5 can simultaneously control the movement of all drive rods 401, thereby allowing users to change the movement mode of several drive rods 401 and several pistons 4 according to different drip irrigation needs, thus improving the applicability of the device.

[0023] To make the detachable connection between the drive rod 401 and the wide plate 5 clearer, this application provides a plurality of fixing pins 501 that slide along the height direction of the wide plate 5. The plurality of fixing pins 501 and the plurality of drive rods 401 are arranged in a one-to-one correspondence. The drive rod 401 is provided with a limiting hole for the fixing pin 501 to be inserted, so that when the fixing pin 501 slides upward to disengage from the limiting hole, the fixing pin 501 will not fix the drive rod 401, thereby allowing the drive rod 401 to slide along the length direction of the transition tube 3 on the wide plate 5; and when the fixing pin 501 slides downward to be inserted into the limiting hole, it will fix the drive rod 401, so that the drive rod 401 and the wide plate 5 are fixedly connected together, and the wide plate 5 can control the movement of the drive rod 401.

[0024] The working principle and usage process of this utility model are as follows: First, when several drip irrigation pipes 2 are used to drip irrigate the same type of crops, several fixing pins 501 are inserted into the limiting holes on the corresponding drive rods 401, so that several drive rods 401 are fixed on the wide plate 5. By controlling the movement of the wide plate 5, several drive rods 401 and pistons 4 move simultaneously, thereby changing the size of several water inlet holes 301 at the same time, so that the drip irrigation flow rate in several drip irrigation pipes 2 can be controlled simultaneously.

[0025] When several drip irrigation pipes 2 are used to drip irrigate different types of crops, the fixing pin 501 can be pulled out from the limiting hole on the piston 4. At this time, the user can control a certain drive rod 401 individually to achieve the purpose of controlling the movement of a certain piston 4 individually, so that the drip irrigation flow rate in several drip irrigation pipes 2 can be adjusted individually.
