Description

TECHNICAL FIELD

[0001] The utility model relates to the technical field of afforestation maintenance device, concretely is afforestation maintenance device with spray function. BACKGROUND

[0002] In today's era, with people's increasing attention to ecological environment and continuous pursuit of a better life, the landscaping industry is ushering in a golden period of rapid development. Today, whether it is a city park, a street, or a rural field, a courtyard, everywhere can be seen carefully planned and designed landscaping landscape. These landscaping areas are not a one-time job after completion, but require regular maintenance, including watering, which is a crucial maintenance step. Water is the source of life and plays an indispensable role in plant growth. Regular watering of plants in landscaping can ensure that they have adequate water and maintain normal physiological metabolism, thereby maintaining a vibrant state and continuously providing people with a visually pleasing and fresh and pleasant ecological environment.

[0003] The existing patent (publication number: CN215454451U) discloses a landscaping maintenance spray device. First, the water in the spray pipe is sprayed in a mist form through the spray nozzle, making the water spray more uniform in the spray area. The spray angle of the spray pipe can be changed by the rotatable rotating ring, thereby ensuring that the area that needs to be sprayed is sprayed. Then, the opening and closing of each electric control valve can be controlled by the PLC control box, thereby spraying the area that needs to be sprayed. Finally, the spray nozzle is protected by the protective cover to prevent damage or clogging of the spray nozzle.

[0004] However, the existing equipment still has some shortcomings. As can be seen from the figure, although the protective cover in the equipment can protect the atomizing nozzle, it is limited to the side. Dust can fall into the interior of the protective cover from the top when not in use, and when accumulated to a certain amount, it can still clog the atomizing nozzle, affecting the normal use of the equipment, leading to frequent cleaning of the interior of the protective cover, and increasing maintenance costs and workload. UTILITY MODEL CONTENTS

[0005] Therefore, the utility model aims to provide a landscaping maintenance device with spray function to solve the technical problems mentioned in the background.

[0006] To achieve the above-mentioned purpose, the utility model provides the following technical scheme: a landscaping maintenance device with spray function, comprising a main water supply pipe, the outer wall of the main water supply pipe is fixedly connected with a plurality of branch water pipes, the outer wall of each branch water pipe is fixedly installed with a butt joint pipe, the top outer wall of the butt joint pipe is connected with a connecting pipe, the top outer wall of the connecting pipe is threadedly connected with a spraying assembly.

[0007] The spraying assembly comprises a shell which is screwed to the outer wall of the top end of the butt joint pipe, a hole cover which is fixedly connected to the center of the upper surface of the shell, an inner ring which is fixedly connected to the inner wall of the bottom end of the shell, an installation ring which is fixedly connected to the inner wall of the center of the inner ring, a sliding rod which is slidingly connected to the center of the installation ring, a sealing plate which is fixedly sleeved to the outer wall of the sliding rod above the inner ring, and a spraying cap which is fixedly connected to the top end of the outer wall of the sliding rod.

[0008] By adopting the above technical scheme, the electrically controlled water valve is first opened to supply water, the water flow extrudes the sealing plate to make the spraying cap extend out of the shell and the spring stretch, and preparation is made for the automatic downward movement of the spraying cap for resetting after the water supply is stopped. When the spraying cap is retracted, the surface spray holes and the through holes of the hole cover are staggered, and when the spraying cap is extended, the surface spray holes and the through holes of the hole cover are connected. The spraying cap and the through hole are used to protect the spray holes when the spraying cap is retracted, prevent dust from blocking the spray holes, improve the stability of the equipment, and reduce the labor intensity of cleaning.

[0009] Further, a plurality of groups of through holes are arranged at equal angles around the center of the outer wall of the hole cover, and the plurality of groups of through holes are divided into two layers according to different horizontal heights, and the two layers of through holes are staggered with each other.

[0010] By adopting the above technical scheme, the two layers of through holes can cooperate with the two layers of staggered spray holes. When the spraying cap is retracted, one layer of spray holes and one layer of through holes are staggered with each other to close the spray holes and prevent dust from blocking the spray holes.

[0011] Further, a first limiting ring is fixedly connected to the bottom end of the outer wall of the sliding rod, a spring is sleeved to the outer wall of the sliding rod, and a rubber gasket is fixedly connected to the lower surface of the sealing plate.

[0012] By adopting the above technical scheme, the sliding rod is limited by the first limiting ring to prevent the sliding rod from sliding excessively and falling off, improve the stability of the equipment, the spring can prepare for the automatic downward movement of the spraying cap for resetting after the water supply is stopped, and the rubber gasket can enhance the airtightness between the sealing plate and the installation ring to prevent water seepage.

[0013] Further, the two ends of the spring are fixed to the lower surface of the sealing plate and the upper surface of the installation ring respectively, and the top end of the spring is not in contact with the rubber gasket.

[0014] By adopting the above technical scheme, the two ends of the spring are fixed to the lower surface of the sealing plate and the upper surface of the installation ring respectively to stretch the force storage when the spraying cap moves upward, and then the sealing plate loses the upward force when the water supply is stopped. At this time, the spring rebounds to drive the spraying cap and the sealing plate to move downward for resetting. The inner diameter of the rubber gasket is greater than the outer diameter of the spring, which can prevent the spring from extruding the rubber gasket and prolong the service life of the rubber gasket.

[0015] Further, the cross-sectional shape of the spraying cap is in the shape of the letter "U", and the top end of the outer wall of the sliding rod is fixed to the center position of the inner wall of the spraying cap.

[0016] By adopting the above technical solution, when the spray cap with a cross-sectional shape of the letter "U" moves upward, the water flows through the inner wall of the spray cap to the spray hole.

[0017] Furthermore, a limit ring is fixedly sleeved on the bottom outer wall of the spray cap, the spray cap penetrates the outer wall of the upper surface of the housing and is slidably connected to the orifice cover, and a spray hole is opened at the position corresponding to the through hole of the spray cap.

[0018] By adopting the above technical solution, the limit ring can provide a limit for the spray cap, prevent the spray cap from slipping off, and ensure the stability of the equipment.

[0019] Furthermore, the outer wall of the housing is provided with protective vertical grooves, and an electrically controlled water valve is fixedly installed on the outer wall of the connecting pipe below the spraying assembly.

[0020] By adopting the above technical solution, the protective vertical grooves on the outer wall of the shell can increase friction and facilitate the installation of the rotating shell.

[0021] In summary, the present invention has the following main advantages:

[0022] This invention first opens the electrically controlled water valve to supply water. The water flow squeezes the sealing plate, causing the spray cap to extend out of the housing and the spring to stretch. This prepares for the spray cap to automatically move down and reset after the water supply stops. When the spray cap retracts, its surface spray holes and the through holes of the orifice cover are staggered. When it extends, they are connected. The automatically retractable spray cap and through holes protect the spray holes when the spray cap retracts, preventing dust from clogging the spray holes, improving equipment stability, and reducing the intensity of manual cleaning.
