The working principle of the invention and process for using: in the fertilizer apparatus that the agricultural is applied fertilizer with layered displacement-variable in use, head Device is first mounted on tractor rear portion, mounting base 17 is connected by U bolt and the installation of seeder crossbeam, then rotary motion Casing 2003 selects mounting rack 1 close to horizontal position angle, to 2004 interpolation of locking screw holes so that oscillating rod 2005 is swung Enter bolt, rotating casing 2003 and oscillating rod 2005 are fixed, then turning knob 15, drives 14 turns of height adjusting screw rod It is dynamic, further such that mounting rod 16 is moved up and down along height adjusting screw rod 14,16 position of mounting rod is adjusted, so that mounting rack 1 Stop when holding level；

Device after the installation is completed, is put into fertilizer into fertilizer box 2, is internally located at fertilizer partition 3 and fertilizer box in fertilizer box 2 The fertilizer for the identical type stored between 2 inner walls, fertilizer box 2 are internally located between fertilizer partition 3 and are placed with second at position Fertilizer, and the variable fertilization controller placed on driving motor 803 and tractor is electrically connected, then according to crop demand, Trench digging and primary thickness of earth-fill cover are adjusted；

When trench digging position is adjusted, fixing bolt 1802 is removed first, is ditched then according to actual demand is mobile Device handle 1803 is properly ditched highly so that furrowing blade 1809 is located at, then selection and through-hole 1804 similar in fixing bolt 1802, Plough handle 1803 is adjusted again, so that fixing bolt 1802 passes through the rubber ring 1807 inside through-hole 1804, because of fixing sleeve Connection is engaged with fixing sleeve 1801 by screw thread in 1801 bottoms, ensure that the stabilization in 1803 use process of plough handle, completes Ditching depth is adjusted in completion, and the buffer spring 1806 by connecting on the outside of rubber ring 1807, avoids furrowing blade 1809 Encounter hard object cause plough handle 1803 squeeze fixing bolt 1802, and cause fixing bolt 1802 damage the case where, it is then right Primary thickness of earth-fill cover is adjusted, and crank 1903 is rotated when adjusting, drives depth adjustment screw rod 1902 to rotate, because of internally threaded sleeve 1905 engage connection by screw thread with depth adjustment screw rod 1902, drive internally threaded sleeve 1905 along depth adjustment screw rod 1902 It is mobile to fixed block 1904, so that the second connecting rod 1906 is incrementally increased with horizontal sextant angle, and then push drum connection Block 1907 moves down, so that mounting post 1908 drives trailing bar 1909 to move down, it is deep to complete the primary earthing of trailing bar 1909 The adjusting of degree；

In tractor driving device moving process, variable fertilization controller controls driving motor 803 according to fertilizer formula Rotation, when driving motor 803 rotates, because fertilizer box 2 is internally located at the phase stored between fertilizer partition 3 and 2 inner wall of fertilizer box Congener fertilizer, fertilizer box 2, which is internally located between fertilizer partition 3, is placed with second of fertilizer at position, so that after metering Fertilizer is fallen in mixer 5, and is separated by mixing partition 6, so that the fertilizer mixed proportion of 6 two sides of mixing partition is variable The calculated optimal proportion of fertilization controller, in moving process, furrowing blade 1809 is ditched, variable fertilization controller control bit Driving motor 803 between trailing bar 1909 and furrowing blade 1809 starts, so that the mixed fertilizer in 6 side of mixing partition Material falls to bottom of trench, and then soil a part of ditch two sides is back into ditch by trailing bar 1909, and 1909 height of trailing bar is upper It states and has been adjusted in operation, so that the driving electricity between variable fertilization controller control trailing bar 1909 and earthing roller 2007 Machine 803 starts, so that the mixed fertilizer in 6 other side of mixing partition falls to the soil surface that lid covers, and then realize Remaining soil is pressed into ditch finally by earthing roller 2007, realizes the covering of soil, avoid fertilizer direct by the purpose of layering Waste is lost caused by exposure.

Finally, it should be noted that being not intended to restrict the invention the foregoing is merely preferred embodiment of the invention, to the greatest extent Present invention has been described in detail with reference to the aforementioned embodiments for pipe, for those skilled in the art, still can be with It modifies the technical solutions described in the foregoing embodiments or equivalent replacement of some of the technical features.It is all Within the spirit and principles in the present invention, any modification, equivalent replacement, improvement and so on should be included in guarantor of the invention Within the scope of shield.
