Description

Online straw pipeline forming machine for irrigation

Technical Field

The invention belongs to the technical field of straw pipeline preparation, and particularly relates to an on-line forming machine for a straw pipeline for irrigation.

Background

After years of efforts, the national irrigation area reaches 6800 kilohm 2 (10.02 hundred million acre) by 2011, wherein the irrigation area of cultivated land is 6146.7 kilohm 2 (9.22 hundred million acre), and the irrigation area exceeds half of the cultivated land area for the first time. However, in the existing irrigation area, the water-saving irrigation area is less than 40%, the high-efficiency water-saving irrigation (short for spray irrigation, micro-irrigation, high-standard low-pressure pipeline water delivery irrigation and the like) is less than 15%, and the spray irrigation and micro-irrigation area is less than 6%. It is known that in the above irrigation forms, except for sprinkling irrigation and micro-irrigation, most of the fields are still ground irrigation, namely the problem of the frequently-mentioned last kilometer of farmland irrigation, once the fields are dry, the defects of the existing farmland irrigation are exposed, and especially the demand gap of the development and production of an efficient water-saving technology is large.

The low mechanization degree of farmland irrigation is one of the main obstacles in the popularization of irrigation technology, and has become a short leg in the development of modern agriculture. In the field irrigation, apart from partial micro-irrigation and sprinkler irrigation systems, the whole irrigation system is in a stage mainly comprising manpower and secondarily comprising machinery, and most irrigation technologies (such as ridging, manually moving pipes, opening and closing valves and the like) cannot avoid heavy manual labor, which is also an important reason for pushing and not widening most efficient water-saving irrigation technologies at present.

The soil foundation soil fertility is the foundation for high quality and high yield of crops, and even the soil foundation soil fertility is in positive correlation with the economic development capability of a country and a region. The crop straws all contain a certain amount of various elements such as carbon, nitrogen, phosphorus, potassium and the like, and are precious renewable resources. The straw returning technology can not only rush the farming season and the accumulated temperature, but also avoid the problems of environmental pollution caused by rotting and burning, has obvious effects on drought resistance, soil moisture conservation, reduction of the using amount of chemical fertilizers, production cost saving, ecological environment protection and the like, and is one of the simplest and most effective methods for improving the soil foundation fertility.

The drainage pipe condition is generally laid respectively, that is, the irrigation pipe and the drain pipe are laid respectively, the irrigation pipe supplies water from inside to outside, the drain pipe adopts perforated pipe and the like, the two have different pressures, most plastic pipes (PVC, PE and the like) are made of materials, and the rat way is that one hole is pulled out underground by the rat plough on the basis of the existing land to play a drainage role. The structure of the rat way is unstable, and the rat way is easy to collapse particularly after being flushed with water, so that the drainage effect is influenced.

At present, the technology taking straws as one component for pipeline production exists in the market, but in the production process, the straws are denatured and are not the straws any more, and the straws cannot be naturally contacted due to the wrapping of plastics and are difficult to decompose and restore into soil. The production machinery is mostly industrialized operation, namely various pipes are produced in a plastic plant and then are pulled to the field to be laid according to the design. The laying process is manual or mechanical, and no technology for completing mechanical construction of raw materials at one time through field processing is available in the market.

The number of the elastic pieces 86 may be the same as or different from the number of the blades 83, as long as a plurality of blades are symmetrically arranged on the outer circumference of the solid structure of the rear half part of the pipe inner diameter adjustable unit 84.

The blade is a plurality of, makes on the one hand have a plurality of linear gaps on the straw pipeline after the shaping, can increase irrigation efficiency, and on the other hand for adjustment mechanism 82 is fixed in outer wall 81 through a plurality of blades more firm, and the stability of better assurance adjustment mechanism 82 position effectively guarantees the homogeneity of straw pipeline pipe thickness.

Other structures of the second embodiment are the same as those of the first embodiment, and are not described again.

The invention has the following beneficial effects:

(1) Materials are directly taken on site, and raw materials (straws and a small amount of soil) are collected, so that the cost is reduced, and the time and the labor are saved;

(2) The straw pipeline can be directly used without treatment after being formed, the production is convenient, and the period is short;

(3) The pipeline which takes the straws and the soil as main raw materials has double functions of irrigation, water storage and drainage;

(4) Realizes the one-time mechanical operation of raw material collection, field processing and field laying.

Finally, it should be noted that: the above embodiments are only for illustrating but not limiting the technical solution of the present invention, and any equivalent substitutions and modifications or partial substitutions made on the present invention without departing from the spirit and scope of the present invention should be covered by the protection scope of the claims of the present invention.
