Description

Technical Field

[0001] The utility model relates to the field of water conservancy, in particular to a pipeline outlet conversion device. Background Art

[0002] At present, the crops used for saline-alkali land improvement are generally rice. However, after the successful improvement of saline-alkali land, the rice fields will often be changed to plant crops such as wheat and corn that require drip irrigation. At this time, the diameter of the pipe used for rice irrigation often cannot meet the requirements of drip irrigation, so a device that can convert the pipe outlet diameter is needed. Summary of the invention

[0003] The purpose of the utility model is to provide a pipeline outlet conversion device, which has a simple and practical structure, is easy to construct, adapts to displacement, and can adjust the diameters of the upper and lower hoops to adapt to various pipelines. The technical solution is as follows:

[0004] A pipeline outlet conversion device comprises a first rubber tapered tube, an upper fixing hoop, a lower fixing hoop and a diameter adjustment device, characterized in that: the upper fixing hoop is fixed to the large end of the rubber tapered tube, the diameter adjustment device is fixed to the small end of the rubber tapered tube, the diameter adjustment device is an aluminum tapered tube, the large end of the diameter adjustment device is fixedly connected to the small end of the rubber tapered tube, the first rubber tapered tube and the diameter adjustment device form a water passage, and the lower fixing hoop is connected to the peripheral wall of the diameter adjustment device through a second rubber tapered tube.

[0005] The upper fixing hoop is set at one end of the larger pipe and is tightened and fixed by the upper fixing hoop, inserted into the water inlet of the pipe to be connected through the diameter adjustment device, set at the pipe mouth through the lower fixing hoop, and is tightened and fixed by the lower fixing hoop. Due to the elastic form of the second rubber conical tube, it can be suitable for installation at pipe mouths of various diameters.

[0006] The utility model adopts the method of upper and lower steel hoops and rubber tapered tubes, and is provided with a diameter adjustment device to adapt to pipelines of different diameters.

[0007] The beneficial effect achieved by the utility model is that by connecting pipes of different diameters, the pipes of farmland that originally needed to be replaced do not need to be replaced, thus saving manpower, time and cost and improving efficiency. BRIEF DESCRIPTION OF THE DRAWINGS

[0009] Figure 2 It is a cross-sectional view of the utility model. DETAILED DESCRIPTION

[0010] The following will be combined with the drawings in the embodiments of the utility model to clearly and completely describe the technical solutions in the embodiments of the utility model. Obviously, the described embodiments are only part of the embodiments of the utility model, not all of the embodiments. Based on the embodiments in the utility model, all other embodiments obtained by ordinary technicians in this field without creative work are within the scope of protection of the utility model.

[0011] Please refer to Figures 1-2, a pipeline outlet conversion device includes a first rubber conical tube 1, an upper fixing hoop 2, a lower fixing hoop 3 and a diameter adjustment device 4, characterized in that: the upper fixing hoop 2 is fixed to the large end of the rubber conical tube, and the diameter adjustment device 4 is fixed to the small end of the rubber conical tube. The diameter adjustment device is an aluminum conical tube, and the large end of the diameter adjustment device is fixedly connected to the small end of the rubber conical tube. The first rubber conical tube and the diameter adjustment device form a water passage, and the lower fixing hoop is connected to the peripheral wall of the diameter adjustment device through the second rubber conical tube 5.

[0012] The upper fixing hoop is set on one end of the larger pipe and is tightened and fixed by the upper fixing hoop, inserted into the water inlet of the pipe to be connected through the diameter adjustment device, set on the pipe mouth through the lower fixing hoop, and is tightened and fixed by the lower fixing hoop. Due to the elastic form of the second rubber conical tube 5, it can be suitable for installation at pipe mouths of various diameters.

[0013] The upper fixing hoop and the lower fixing hoop are of the same combination and size, and are both provided with an adjustable ring piece 6 and a tightening bolt 7. The adjustable ring piece is provided with a plurality of connecting holes, and the connecting holes are fixed with the tightening bolts and nuts.

[0014] Although the embodiments of the present invention have been shown and described, it will be appreciated by those skilled in the art that various changes, modifications, substitutions and variations may be made to the embodiments without departing from the principles and spirit of the present invention, and that the scope of the present invention is defined by the appended claims and their equivalents.
