Description

Technical Field

[0001] This utility model relates to the field of drip irrigation system technology, and in particular to a drip irrigation system for planting Chinese medicinal herbs. Background Technology

[0002] In the process of modern agricultural development, the scale of Chinese medicinal herb cultivation has been continuously expanding. Traditional irrigation methods, due to their large water consumption and low water resource utilization rate, are prone to problems such as soil compaction and decline in the quality of medicinal herbs, making it difficult to meet the needs of refined cultivation of Chinese medicinal herbs. As a result, drip irrigation systems are mostly used to irrigate the cultivated Chinese medicinal herb crops.

[0003] Most existing drip irrigation systems lack a mechanism to clearly alert users when drip cans become clogged, making it difficult to detect blockages in a timely manner. This can affect the continuous and effective irrigation of medicinal plants corresponding to the location of the clogged drip can. Utility Model Content

[0004] In view of this, the present invention provides a drip irrigation system for planting Chinese medicinal herbs to solve the problem of the lack of a mechanism that can provide a conspicuous reminder of the blockage of the drip irrigation head.

[0005] The technical solution proposed by this utility model is: a drip irrigation system for planting Chinese medicinal herbs, specifically including a water distribution hose, on which a row of rigid drainage pipes arranged at equal intervals are fixedly connected;

[0006] A shielded piston sleeve is fixedly connected to the wall of the rigid drain pipe and communicates with it. A transparent piston sleeve is fixedly connected to the opening at the head of the shielded piston sleeve. The transparent piston sleeve and the shielded piston sleeve are connected together to form a relatively long piston tube sleeve. A sliding shaft is slidably installed inside the piston tube sleeve in the form of a spring push. A mounting plate is fixedly connected to the head of the sliding shaft. A rubber piston is fixedly connected to the mounting plate. The outer circumference of the rubber piston is in frictional and extrusion contact with the inner circumference of the piston tube sleeve. An observation layer is provided on the surface of the rubber piston. A drip head is threadedly connected to the top opening of the rigid drain pipe. When the drip head is unobstructed, the rubber piston is pushed and slid into the shielded piston sleeve by the spring that pushes the sliding shaft. When the drip head is blocked, the piston tube sleeve is pressurized. The rubber piston is pushed and slid into the transparent piston sleeve by the increased pressure of the pressurization.

[0007] Furthermore, the transparent piston sleeve has an integrally formed baffle with an increased diameter at its tail end, and the sliding shaft and the baffle are slidably connected through it, with a limit plate fixedly connected to the tail end of the sliding shaft.

[0008] A spring that pushes the slide shaft is fitted onto the slide shaft and is compressed and clamped between the mounting plate and the stop plate, with the limiting plate abutting against the stop plate.

[0009] Furthermore, a cleaning ring is slidably fitted on the piston sleeve, and a ring-shaped cleaning sponge is fixed to the inner circumference of the cleaning ring by Velcro. The inner circumference of the ring-shaped cleaning sponge is in frictional contact with the outer circumference of the piston sleeve.

[0010] Furthermore, a knob ring is rotatably mounted on the top part of the rigid drain pipe, and a connecting rod is rotatably connected between the knob ring and the cleaning ring.

[0011] Furthermore, the top of the cleaning ring is integrally formed with a sliding lug, and an L-shaped guide rod is fixedly connected between the rigid drain pipe and the baffle. The sliding lug and the horizontal rod segment of the L-shaped guide rod are in sliding engagement.

[0012] Furthermore, it also includes a water pump, with a water guide hose connected to the water pump's outlet pipe, a water distribution hose connected to the first end of the water guide hose, and water distribution hoses arranged on the water distribution hose.

[0013] Furthermore, both ends of the water guiding hose and the beginning of the water distribution hose are closed structures.

[0014] The drip irrigation system for planting Chinese medicinal herbs provided by this utility model has the following beneficial effects:

[0015] 1. When a drip head is clogged, the piston sleeve is pressurized internally. The rubber piston is pushed and slid into the transparent piston sleeve by the increased pressure of the pressurization. Since the rubber piston is conspicuously red, when the rubber piston is pushed into the transparent piston sleeve, the staff can easily and promptly find the position of the rubber piston through the transparent piston sleeve. Based on this, they can determine that the drip head corresponding to the position of the rubber piston is clogged, and promptly unclog the clogged drip head to restore the drip irrigation performance of the clogged drip head, ensuring normal and continuous drip irrigation for the Chinese herbal plants corresponding to the position of the clogged drip head.

[0016] 2. The knob ring, connecting rod, and cleaning ring are connected to form a crank-slider mechanism. Through this mechanism, turning the knob ring in both directions can drive the cleaning ring and the annular cleaning sponge to slide back and forth along the piston sleeve, wiping away the wet soil adhering to the piston sleeve and restoring the transparent piston sleeve to a clear and transparent state. This allows staff to clearly observe whether the rubber piston is pushed into the transparent piston sleeve and accurately determine whether the drip head is blocked. Compared with the existing design that directly wipes the piston sleeve with fingers, this is more convenient and efficient, has a better cleaning effect, and can avoid the wet soil from sticking and soiling the fingers.

[0036] Please refer to Figures 1 to 6 Example 1:

[0037] This embodiment proposes a drip irrigation system for planting Chinese medicinal herbs, including a water distribution hose 4, on which a row of equally spaced rigid drainage pipes 5 are fixedly connected;

[0038] A shielded piston sleeve 503 is fixedly connected to the wall of the rigid drain pipe 5 and communicates with it. A transparent piston sleeve 504 is fixedly connected to the opening at the head of the shielded piston sleeve 503. The transparent piston sleeve 504 and the shielded piston sleeve 503 are connected together to form a relatively long piston tube sleeve. A sliding shaft 6 is slidably installed inside the piston tube sleeve in the form of a spring push. A mounting plate 602 is fixedly connected to the head of the sliding shaft 6. A rubber piston 7 is fixedly connected to the mounting plate 602. The outer circumference of the rubber piston 7 is in frictional and extrusion contact with the inner circumference of the piston tube sleeve. An observation layer is provided on the surface of the rubber piston 7. The observation layer is conspicuously red. Specifically, the observation layer can be a waterproof coating or a red sticker, or the rubber piston 7 itself can be red, as long as it is convenient for the user to observe. A drip head 8 is installed on the top opening of the rigid drain pipe 5 by screwing it in. The shielded piston sleeve 503 is an opaque structure.

[0039] Preferably, the tail end of the transparent piston sleeve 504 is integrally formed with a baffle 5041 with an increased diameter, the slide shaft 6 and the baffle 5041 are slidably connected through, and the tail end of the slide shaft 6 is fixedly connected to a limiting plate 601; a spring sleeve for pushing the slide shaft 6 is fitted on the slide shaft 6 and is compressed and clamped between the mounting plate 602 and the baffle 5041, and the limiting plate 601 abuts against the baffle 5041.

[0040] Preferably, the first end opening of the shielded piston sleeve 503 is provided with an annular threaded groove 5031, and the first end opening of the transparent piston sleeve 504 is integrally formed with a threaded ring 5042. The threaded ring 5042 is threadedly connected to the annular threaded groove 5031, and the inner diameters of the threaded ring 5042 and the annular threaded groove 5031 are the same as the inner diameter of the piston sleeve.

[0041] Implementation 2: This embodiment is based on Implementation 1, but with the following additions:

[0042] This embodiment includes a cleaning ring 505, which is slidably mounted on the piston tube sleeve. A ring-shaped cleaning sponge 5051 is fixed to the inner circumference of the cleaning ring 505 by Velcro, and the inner circumference of the ring-shaped cleaning sponge 5051 is in frictional contact with the outer circumference of the piston tube sleeve. A knob ring 501 is rotatably mounted on the top part of the rigid drain pipe 5, and a connecting rod 5011 is rotatably connected between the knob ring 501 and the cleaning ring 505. A sliding lug 5052 is integrally formed on the top of the cleaning ring 505. An L-shaped guide rod 502 is fixedly connected between the rigid drain pipe 5 and the baffle 5041, and the sliding lug 5052 and the horizontal rod section of the L-shaped guide rod 502 are in sliding engagement.

[0043] Preferably, it also includes a water pump 1, the outlet pipe of the water pump 1 is connected to a water guide hose 2, and its inlet pipe is connected to an external irrigation water source through an external pumping pipe. The first end of the water guide hose 2 is connected to a water distribution hose 3, and water distribution hoses 4 are connected and arranged on the water distribution hose 3.

[0044] Preferably, both ends of the water guiding hose 2 and the beginning of the water distribution hose 4 are closed structures.

[0045] The following is a detailed explanation of the working principle, specific details, implementation steps, functions and interrelationships of each feature, and their role in realizing this technical solution: The water pump 1 is used to pump and transport irrigation water to the water guide hose 2. The irrigation water entering the water guide hose 2 is continuously transported to the water distribution hose 3 and a row of water distribution hoses 4 under the pressure of the water pump 1. The row of water distribution hoses 4 is distributed between the rows of Chinese herbal medicine plants, and the position of the row of drip heads 8 on each water distribution hose 4 corresponds one-to-one with the row of Chinese herbal medicine plants in which it is located. The irrigation water transported to the water distribution hose 4 is dripped out through the row of drip heads 8 on the water distribution hose 4 to drip irrigate the Chinese herbal medicine plants at the corresponding positions in the row of Chinese herbal medicine plants.

[0046] When the drip head 8 is unobstructed, the rubber piston 7 is pushed and slid into the shielded piston sleeve 503 by the spring on the sliding shaft 6. When the drip head 8 is blocked, the piston sleeve is pressurized, and the rubber piston 7 is pushed and slid into the transparent piston sleeve 504 by the increased pressure of the pressurization. Since the rubber piston 7 is conspicuously red, when the rubber piston 7 is pressed and pushed into the transparent piston sleeve 504, the staff can easily and promptly find the position of the rubber piston 7 through the transparent piston sleeve 504, and determine that the drip head 8 corresponding to the position of the rubber piston 7 is blocked. The blocked drip head 8 can be cleared in time to restore the drip irrigation performance of the blocked drip head 8 and ensure normal and continuous drip irrigation for the Chinese herbal plants corresponding to the position of the blocked drip head 8.

[0047] It is worth noting that when the rubber piston 7 is pushed into the transparent piston sleeve 504, it drives the sliding shaft 6 and the mounting plate 602 to slide synchronously. The mounting plate 602 compresses the spring on the sliding shaft 6. When the drip head 8 clears the blockage, the pressure inside the piston sleeve is released, and the compressed spring loses its pushing force. It can push back to drive the sliding shaft 6 and the rubber piston 7 back to their original position, and drive the rubber piston 7 to slide into the shielded piston sleeve 503, thus relieving the reminder of the blockage.

[0048] The knob ring 501, connecting rod 5011, and cleaning ring 505 are connected to form a crank-slider mechanism. Through this mechanism, the forward and reverse rotation of the knob ring 501 can drive the cleaning ring 505 and the annular cleaning sponge 5051 to slide back and forth along the piston sleeve, wiping away the wet soil adhering to the piston sleeve and restoring the transparent piston sleeve 504 to a clear and transparent state. This allows the staff to clearly observe whether the rubber piston 7 is pushed into the transparent piston sleeve 504 and accurately determine whether the drip head 8 is blocked. Compared with the existing design of directly wiping the piston sleeve with fingers, this is more convenient and efficient, has a better cleaning effect, and can avoid the wet soil from sticking and soiling the fingers.
