Description

Technical Field

[0001] This utility model relates to the field of irrigation sprinkler technology, and in particular to a timed irrigation sprinkler for municipal green belts. Background Technology

[0002] Currently, different varieties of seedlings are planted in municipal green belts to enhance their aesthetics. However, different seedlings have different water requirements. When watering municipal green belts, it is necessary to manually water them at fixed times. However, manual watering is time-consuming and labor-intensive, and it is impossible to accurately control the amount of water. This results in different amounts of water being poured into different seedlings, which can easily lead to insufficient watering or excessive watering, causing the soil to become saturated, resulting in root rot or water overflow. Therefore, a timed watering nozzle for municipal green belts has been designed to solve the above problems. Utility Model Content

[0003] In view of the shortcomings of existing irrigation sprinklers, the purpose of this utility model is to provide a timed irrigation sprinkler for municipal green belts, which has the advantages of quantitative irrigation and controllable irrigation time.

[0004] To achieve the above objectives, the present invention employs the following technical solution: a timed irrigation sprinkler head for municipal green belts, comprising a cylindrical body, a nozzle, a sliding plate, a switch assembly, an opening adjustment bolt, and a timed action frame. The top of the cylindrical body has an inlet for connecting a water pipe, and the bottom of the cylindrical body has a detachable nozzle. The cylindrical body has a flow channel connecting the inlet and the nozzle. The switch assembly is located in the middle of the flow channel for connecting or blocking the flow channel. One side of the cylindrical body has a mounting box, and the mounting box contains a sliding plate that is slidably connected. The side of the sliding plate is rotatably connected to an opening adjustment bolt, which extends out of the mounting box and engages with it. The end face of the sliding plate is provided with a timed action frame for the timed start switch assembly.

[0005] Preferably, the switching assembly includes a valve plate and a spring. The valve plate is radially slidably connected to the middle of the cylindrical body. The valve plate is used to block or connect the flow channel. Both ends of the valve plate penetrate the cylindrical body. The spring is disposed on one side of the valve plate to force the valve plate to block the flow channel.

[0006] More preferably, the sliding direction of the valve plate is the same as that of the sliding plate;

[0007] Preferably, the timing action frame includes a hollow cam, a reduction gear, a drive gear, and a drive motor. The hollow cam is rotatably connected to the end face of the sliding plate. The inner edge of the hollow cam has a gear ring. The drive motor is fixed to the end face of the sliding plate and located at the center of the hollow cam. The output shaft of the drive motor is provided with a drive gear. The reduction gear is rotatably connected to the end face of the sliding plate and located inside the hollow cam. The reduction gear meshes with the gear ring and the drive gear.

[0008] Preferably, the top of the mounting box has an indicator for indicating the amount of water poured, and the top of the sliding plate has a pointer that extends out of the mounting box, the pointer being used to point to the indicator to indicate the amount of water poured;

[0009] The beneficial effects of this utility model are: 1. By controlling the motor speed, the rotation speed of the hollow cam is changed, so that the hollow cam can open the valve plate after a certain period of time, thereby connecting the flow channel and enabling timed watering, thus achieving the effect of timed watering; 2. By rotating the opening adjustment bolt, the sliding plate is moved, thereby changing the opening degree of the hollow cam opening the valve plate, thus achieving the effect of changing the watering volume.

[0016] Please see Figures 1 to 3 The embodiments of this utility model include:

[0017] A timed irrigation sprinkler for municipal green belts includes a cylindrical body 1, a nozzle 2, a sliding plate 3, a switch assembly 4, an opening adjustment bolt 5, and a timed action frame 6. The top of the cylindrical body 1 has a water inlet 11 for connecting a water pipe, and the bottom of the cylindrical body 1 has a detachable nozzle 2. The cylindrical body 1 has a flow channel 12 connecting the water inlet 11 and the nozzle 2. The switch assembly 4 is located in the middle of the flow channel 12 to connect or block the flow channel 12. One side of the cylindrical body 1 has a mounting box 7, and the mounting box 7 has a slidingly connected sliding plate 3. The side of the sliding plate 3 is rotatably connected to the opening adjustment bolt 5, which extends out of the mounting box 7 and engages with it. The end face of the sliding plate 3 has a timed action frame 6 for the timed start switch assembly 4.

[0018] The switch assembly 4 includes a valve plate 41 and a spring 42. The valve plate 41 is radially slidably connected to the middle of the cylindrical body 1. The valve plate 41 is used to block or connect the flow channel 12. Both ends of the valve plate 41 penetrate the cylindrical body 1. The spring 42 is disposed on one side of the valve plate 41 to force the valve plate 41 to block the flow channel 12.

[0019] The sliding direction of the valve plate 41 is the same as that of the sliding plate 3.

[0020] The timing action frame 6 includes a hollow cam 61, a reduction gear 62, a drive gear 63, and a drive motor 64. The hollow cam 61 is rotatably connected to the end face of the sliding plate 3. The inner edge of the hollow cam 61 has a gear ring 65. The drive motor 64 is fixed to the end face of the sliding plate 3 and located at the center of the hollow cam 61. The output shaft of the drive motor 64 is provided with a drive gear 63. The reduction gear 62 is rotatably connected to the end face of the sliding plate 3 and located inside the hollow cam 61. The reduction gear 62 meshes with the gear ring 65 and the drive gear 63.

[0021] The top of the mounting box 7 has an indicator 8 for indicating the amount of water to be poured, and the top of the sliding plate 3 has a pointer 9 that extends out of the mounting box 7. The pointer 9 is used to point to the indicator 8 to indicate the amount of water to be poured.

[0022] With the above settings, its specific working principle in actual operation is as follows:

[0023] First, use a hose to connect the water inlet 11 of the sprinkler head to the water supply pipe. Then, point the nozzle 2 at the different varieties of seedlings that need to be watered, thus completing the installation of the watering sprinkler head.

[0024] When timed watering is required, the rotation speed of the hollow cam 61 is changed by controlling the motor speed, so that the hollow cam 61 can open the valve plate 41 after a certain period of time, thereby connecting the flow channel 12 and enabling timed watering, thus achieving the effect of timed watering.

[0025] When it is necessary to change the irrigation water volume, the sliding plate 3 is moved by rotating the opening adjustment bolt 5. The sliding plate 3 moves the hollow cam 61 away from or closer to the valve plate 41. While adjusting, observe the pointer 9 pointing to the indicator plate 8. This can change the opening of the hollow cam 61 opening the valve plate 41, thereby achieving the effect of changing the irrigation volume.

[0026] The above description is merely an embodiment of this utility model and does not limit the patent scope of this utility model. Any equivalent structural or procedural transformations made based on the description and drawings of this utility model, or direct or indirect applications in other related technical fields, are similarly included within the patent protection scope of this utility model.
