Existing drainage and mole implement has some drawbacks, as it has one working body, lower productivity, during operation the stability of the course is lost in the depth of the gun and the weakness of its frame. The proposed new improved drainage - mole implements, has high productivity, high machine utilization factor (MUF) and the extreme working bodies which made with inclined racks to save from collapsing from above the shells of mole drainage. It has a working width of up to 4 m, the frame consists of three parts, the middle frame is hung on a tractor with three point connections, U-shaped frames with a wide grip of up to 1 m are put on the middle frames on both sides, and between the working body there is a side and average of 2 m, and you can reduce their distance to 2 m. The depth of mole drainage formation is selected depending on the dependence of the mechanical compositions and the degree of soil salinity. The working bodies for the formation of mole drainages, the cone cylinder has a diameter of 0.105-0.110 m, the height of the stand is 1.0-1.2 m, the length of the steel cable is 0.30-0.35 m connecting the posts with the cone of the cylinder, the working width is wave-shaped bit 0,055-0,080 m, the angle of installation of the working body 27-300 and the speed of the unit 1.24-1.36 m / s with this parameter provides high-quality process execution. When using a drainage mole gun in highly saline soil, harmful salts from the soil are reduced by 5-6 times, the desalinization coefficient is 7.4 and this tool can be used after 2-3 years.
