Description

TECHNICAL FIELD

[0001] The present application relates to the field of irrigation tape joints, in particular to a farmland water conservancy irrigation tape adapter. BACKGROUND

[0002] At present, drip irrigation tape is a common way of farmland water-saving irrigation, which drips water and nutrients required by crops into the soil of crop root zone evenly through the irrigation tape and the drip irrigation tape installed on the main pipe tape.

[0003] The existing irrigation tape is mostly a hose without an adapter, and holes are punched on the irrigation tape according to the growth position of crops. Since the irrigation tape does not have elasticity, the diameter of the hole of the irrigation tape needs to be smaller than the diameter of the small end of the irrigation tape adapter. Since the irrigation tape adapter needs to be inserted into the irrigation tape hole and fixed, the insertion end of the adapter is usually wedge-shaped. The adapter is inserted into the irrigation tape hole from the tip, so that the flat end is attached to the inner wall of the main pipe tape, and then the flat end of the adapter is fixed to the irrigation tape by using a nut.

[0004] The existing technical solution in the above has the following defects: the adapter will inevitably be damaged during use. Since the hole is punched on the irrigation tape and the adapter is connected, the adapter needs to be replaced at the original hole when the adapter is replaced. The diameter of the flat end of the adapter is larger than the diameter of the hole of the irrigation tape, and the hole is easily enlarged or torn during disassembly, resulting in damage to the irrigation tape.

[0011] Optionally, a sealing groove is formed on the outer wall of the blocking piece, and a sealing ring is attached to the sealing groove.

[0012] By adopting the technical scheme, when the connecting head main pipe is inserted into the irrigation belt, the side of the sealing ring higher than the outer wall of the blocking piece is tightly attached to the inner wall of the irrigation belt, so that the connection opening is better sealed.

[0013] Optionally, a protective pad is attached to the end face of the fixed nut facing the blocking piece.

[0014] By adopting the technical scheme, the protective pad is located between the fixed nut and the outer wall of the irrigation belt, and when the end face of the fixed nut is tightly attached to the outer wall of the irrigation belt, the protective pad prevents the end face of the nut from wearing the irrigation belt, thereby better protecting the irrigation belt.

[0015] Optionally, a sliding ring is slidably attached to the pipe wall of the connecting head main pipe, the sliding ring is located on the side of the fixed nut away from the protective pad, and the sliding ring is fixedly connected to the end of the traction line outside the pipe wall of the connecting head main pipe.

[0016] By adopting the technical scheme, the traction line is driven by pushing the sliding ring, so that the blocking piece can be retracted.

[0017] Optionally, the end face of the connecting head main pipe away from the fixed nut is a flat end, and the pipe wall is inclined outward from the pipe opening and forms an inclined surface.

[0018] By adopting the technical scheme, the pipe opening of the connecting head main pipe is reduced, thereby facilitating the insertion of the adapter into the opening of the irrigation belt.

[0019] Optionally, an adapter pipe is integrally formed at one end of the connecting head main pipe away from the installation groove, and the adapter pipe is symmetrically arranged at both ends.

[0020] By adopting the technical scheme, the drip irrigation pipe is connected to both ends of the adapter pipe, reducing the excessive punching on the irrigation belt, thereby reducing the damage probability of the irrigation belt.

[0021] Optionally, the adapter pipe is threadedly connected with a locking nut, and a fixing ring is fixedly connected to an end face of the locking nut facing the convex rib, and an inner diameter of the fixing ring is greater than an outer diameter of the convex rib.

[0022] By adopting the above technical scheme, when the drip irrigation pipe is sleeved on the adapter pipe, the locking nut is rotated, the fixing ring is sleeved outside the drip irrigation pipe, the end portion of the drip irrigation pipe is clamped and fixed, and thus the drip irrigation pipe is fixed on the adapter pipe.

[0023] Optionally, the adapter pipe is provided with a valve near a position close to the connector main pipe.

[0024] By adopting the above technical scheme, the valve can be used to control the water amount flowing to the drip irrigation pipe from the irrigation belt, and thus the water amount supplied to crops can be controlled.

[0025] To sum up, the application has the following technical effects:

[0026] 1. The blocking piece can be retracted to prevent the irrigation belt opening from being enlarged when the connector is replaced by arranging the mounting groove;

[0027] 2. The adapter pipe has sealing performance after being connected by arranging the sealing ring on the outer wall of the blocking piece facing the fixing nut, and water leakage is prevented;

[0028] 3. The drip irrigation belt is more firmly connected on the adapter pipe by arranging the threadedly connected locking nut on the adapter pipe. BRIEF DESCRIPTION OF DRAWINGS
