Description

Branch pipe protection bridge for drop irrigation of potato field

Technical Field

The utility model relates to the field of agricultural machinery, concretely relates to drip irrigation potato field branch pipe protects bridge.

Background

Drip irrigation tapes are used for local irrigation by sending water through plastic pipes (drip irrigation pipe guides) to the roots of crops through orifices or drippers on capillary pipes with the diameter of about 10 mm. Is to drip water evenly and slowly, drop by drop, into the soil near the roots of the crops through a dripper or drip tape that has a very small outflow opening.

Most of drip-irrigation potatoes are cultivated in high ridges, the land is gathered to form ridges, and the height of each ridge is 30-40cm generally; the potatoes are planted on the ridges, the drip irrigation belts are buried (or placed on the surface layer) of each ridge, each drip irrigation belt is connected with the branch pipes vertically and then is used for conducting water flowing to finish drip irrigation, namely the drip irrigation belts are parallel to the ridges, and the branch pipes are perpendicular to the ridges and the furrows. The field pipe arrangement drip irrigation system can efficiently and conveniently directly convey water to the roots of crops, but has a problem that after the field pipe arrangement is finished after potato seeding, subsequent farming operations such as intertillage and insecticide spraying need to be carried out by entering a farmland through agricultural mechanized equipment, for example, a tractor enters the field in a ridge-crossing and ditch-grinding mode, namely four wheels of the tractor roll the furrows to advance, and the branch pipes are vertically arranged on the ridges in a ridge direction, so that the branch pipes are exposed in a hollowed-out mode at the positions of the furrows, and when the branch pipes are rolled, the tractor easily breaks holes and bends the branch pipes to cause damage.

For the problems, the existing solution is to pad sand bags on the upper and lower exposed branch pipes at the furrow to protect the branch pipes and then let the tractor pass through, but the solution can solve the problems, but is very inconvenient to implement; firstly, the transportation is inconvenient, the sand bag is not a professional tool, the tractor needs to transport the sand bag to the next section of branch pipe for placing after rolling, and the sand bag is generally heavier and is more laborious to transport; secondly, sand bags are added on the upper portion and the lower portion of the branch pipe, the process is not easy, the upper portion of the branch pipe is good, but the sand bags are required to be inserted below the branch pipe under the branch pipe, and the sand bags and the ditch are difficult to move due to friction; thirdly, because the soil of the furrow is soft and is tightly wrapped by the temporary sandbag, when the tractor rolls, the sharp stones in the sandbag can puncture the branch pipes, which is also one of the reasons that the branch pipes at the furrow are often damaged even if the tractor is supported by the sandbag at present; the breakage of branch pipe can lead to the outflow of intraductal water, not only can erode furrow department and destroy original ridge type and influence potato normal growth, can make the pressure unbalance in the whole drip irrigation system moreover, causes the drip irrigation zone to instil into the liquid manure inequality in farmland, and the drip irrigation zone in distance even is because pressure is not enough and the consequence of can't driping irrigation.
