Description

Technical Field

[0001] The utility model belongs to the technical field of drip irrigation, and in particular relates to an automatic drip irrigation device for flowers. Background Art

[0002] Flower cultivation refers to the process of cultivating and breeding herbaceous plants with ornamental value. During the cultivation process, the growth and breeding of precious flowers generally have high requirements for water irrigation. Some precious flowers can only be irrigated by drip irrigation, so automatic drip irrigation devices are used.

[0003] After searching, a Chinese patent with announcement number CN218736372U discloses a drip irrigation head for flower planting. This patent can send irrigation water in the drip irrigation head into the drainage box through the drainage outlet, and then drip out through the leakage plate in the drainage box for irrigation. At the same time, the lower plate can be conveniently engaged with the lower end surface of the leakage plate through the side plate. By offsetting the through hole 1 of the leakage plate and the through hole 2 of the lower plate, the irrigation water can be dripped out at a slower speed, thereby achieving the function of adjusting the drip irrigation speed, making the irrigation belt suitable for the growth needs of different varieties of flowers, and making irrigation more practical and changeable.

[0004] However, the above patent has the following problems during use:

[0005] 1. During daily use, when the drip irrigation head comes into contact with the soil, soil and other dirt will stick to the outside of the drip irrigation head. After the drip irrigation head is stopped for a period of time, the dirt will solidify in the holes on the outer wall of the drip irrigation head, which will affect the water spraying from the holes when the drip irrigation head continues to be used.

[0006] 2. There is no function to filter the drip irrigation water at the front end of the drip irrigation pipe. A small amount of soil, sand and other particulate matter will be mixed into the irrigation water, which can easily block the drip irrigation port, causing poor or uneven water flow and affecting the planted flowers. Summary of the Invention

[0007] To solve the problems raised in the above-mentioned background technology. The utility model provides an automatic drip irrigation device for flowers, which uses a driving structure to realize the automatic drip irrigation opening and closing operation of the drip irrigation structure, and sets a filter cylinder at the front end of the drip irrigation pipe to filter the drip irrigation water, so as to prevent a small amount of particulate matter such as soil and sand from mixing into the irrigation water and clogging the drip irrigation port, causing poor water flow and affecting flower planting. The driving structure drives the drip irrigation funnel to adjust its height, ensuring that soil cannot come into contact with the drip irrigation head when not watering, so that soil impurities cannot stick to and solidify in the drip irrigation head, and ensure that the drip irrigation head can be used normally after a period of time.

[0008] To achieve the above-mentioned purpose, the utility model provides the following technical solution: an automatic drip irrigation device for flowers, comprising a support frame, a water storage cylinder installed on the support frame, a water outlet at the bottom center of the water storage cylinder connected to a water outlet piston cylinder, a drip irrigation structure connected inside the water outlet piston cylinder, the drip irrigation structure comprising a piston rod and a drip irrigation funnel connected to each other, and a driving structure for driving the drip irrigation funnel and the piston rod to move up and down installed at the bottom of the support frame.

The sealing piston assembly includes an upper piston and a lower piston. The bottom of the piston rod is connected to the drip irrigation funnel. A hollow drip irrigation chamber is provided inside the piston rod. Water inlet holes are opened around the upper end of the hollow drip irrigation chamber between the sealing piston assemblies. A filter mesh cylinder wrapped around the water inlet hole is provided between the sealing piston assemblies. A flow hole is provided at the bottom of the hollow drip irrigation chamber, which is connected to the drip irrigation head at the bottom of the drip irrigation funnel.

[0010] As a preferred solution, the driving structure includes a motor, a driving gear, a screw rod and a guide rod; the screw rod and the guide rod are installed on both sides of the bottom of the support frame through a mounting frame, a driven gear is provided at the upper end of the screw rod, a motor is installed at the bottom of one side of the support frame, a driving gear is provided at the driving end of the motor and is meshed with the driven gear, a screw rod slider is slidingly provided on the screw rod, and is connected to one side of the drip irrigation funnel through the screw rod slider, and the other end of the drip irrigation funnel is slidably connected to the guide rod through a guide slider.

[0011] As a preferred solution, drip irrigation holes are provided around the inner bottom of the drip irrigation funnel.

[0012] As a preferred solution, the water inlet at the top of the water storage cylinder is connected to an external water pipe through a pipe joint; and a transparent observation window is provided on the outer wall of the water storage cylinder.

[0013] As a preferred solution, support rods are provided around the bottom of the support stand.

[0014] Compared with the prior art, the beneficial effects of the present invention are:

[0015] The motor of the utility model controls the start and stop time through the initially set single chip microcomputer, drives the piston rod and the drip irrigation funnel to rise, until the upper piston at the top of the piston rod extends out of the water outlet piston cylinder and enters the water storage cylinder, and the lower piston continues to be sealed and maintained in the water outlet piston cylinder. At this time, the hollow drip irrigation chamber inside the piston rod and the water storage cylinder are opened, the water inside the water storage cylinder is filtered through the filter cylinder and then enters the hollow drip irrigation chamber through the water inlet hole, and flows into the drip irrigation head at the bottom of the drip irrigation funnel from the flow hole at the bottom of the hollow drip irrigation chamber to perform drip irrigation operation on the flowers; the driving structure is used to realize the automatic drip irrigation start and close operation of the drip irrigation structure, and the drip irrigation water is filtered at the front end of the drip irrigation pipe through the filter cylinder to prevent a small amount of particulate matter such as soil and sand from mixing into the irrigation water and clogging the drip irrigation port, causing poor or uneven water discharge and affecting flower planting.

[0016] The driving structure drives the drip irrigation funnel to adjust its height, so that the soil cannot contact the drip irrigation head when irrigation is not needed, ensuring that the soil cannot contact the drip irrigation head when irrigation is not needed, and thus preventing impurities such as soil from sticking and solidifying in the drip irrigation head, thereby ensuring that the drip irrigation head can be used normally after a period of time, thereby ensuring the uniformity of irrigation.
