Furthermore, the lower extreme of discharge opening has a connection piece, the lower extreme of screw rod rotates to be connected on the connection piece, have the ejection of compact breach that runs through the discharge opening on the connection piece, ejection of compact breach is located the lower extreme of cutting part.
The fertilization export is ejection of compact breach relatively less promptly, and is located the rear of cutting part, can make fertilizer be in the extrusion state, and is difficult to lead to the reverse of water to irritate into.
Further, the machine body is fixedly provided with two installation sleeves, the two installation shafts are respectively connected in the installation sleeves in a rotating mode, the installation sleeves are provided with locking screw holes perpendicular to the axis of the installation shafts, and the locking screw holes are connected with locking bolts capable of fixing the installation shafts and the installation sleeves in an internal thread mode.
The inclination angle of the fertilization slotting tool can be changed through the relative positions of the charging barrel and the rotating shaft so as to adjust the fertilization position, namely the depth of the fertilizer in the soil.
Furthermore, a feeding window is arranged on the circumferential surface of the charging barrel, and a stop door is arranged at the feeding window.
Furthermore, every installation epaxial articulated have a linking arm, is connected with one between two linking arms and catches up with the plain-barreled roll, catch up with the plain-barreled roll and rotate to be connected on the installation arm.
The leveling roller is used for compensating and burying a soil opening formed by the fertilizing slotting tool, so that subsequent rice transplanting is not affected, and a cutter groove formed on the surface of soil by the fertilizing slotting tool can be avoided, and fertilizer and water can be quickly mixed.
Furthermore, a material receiving hopper is fixedly arranged on the charging barrel, and each fertilization slotting tool is positioned in the material receiving hopper.
Can be through rotatory feed cylinder, when this base fertilizer machine of giving fertilizer to give fertilizer is in ground walking state, make the slotting tool up of giving fertilizer, fertilizer can be located after being extruded by the screw rod promptly and connect the hopper in, avoid the waste of fertilizer, before reentrant field, can pour out the fertilizer that connects in the hopper, then from newly adding to the feed cylinder.
