Description

Technical Field

[0001] The invention relates to a fertilizing operation component of a crop seeder. Background Art

[0002] With large-scale operations, a large number of combined seeders are widely used. The general operation plan is to first use a plowshare to open furrows and turn the soil, then sow the seeds through a seeder, and simultaneously apply fertilizer on one side of the seeds, and finally, cover the seeds and fertilizers through a cover.

[0003] For example, CN105993250A is a multifunctional agricultural soil loosening, fertilizing and seeding machine. Although it discloses a technical solution, in practice, due to the distance between fertilizer and seeds, a lot of fertilizer is wasted. At the same time, the seeds cannot fully absorb it, resulting in the inability of the roots to take root better and poor resistance to lodging. However, if the fertilizer and seeds are sown at the same time, the fertilizer will cause the seeds to burn. How to avoid burning the seeds and at the same time, fully utilize the fertilizer and achieve better rooting has become a technical problem that needs to be solved urgently. Summary of the invention

[0061] In step CC, first, during the continuous conveying of mud fertilizer, the mud fertilizer falls into the extrusion box through the middle through hole of the mud fertilizer; then, under the action of the rotating screw shaft, the mud fertilizer continuously passes through the gap between the rotating screw shaft and the guide sleeve, the inner cavity of the connecting seat, and is output from the mud fertilizer output pipe and sent to the feed rotary joint through the rubber hose;

[0062] When there is no need to supply mud fertilizer, the gearbox assembly is shifted to make the rotating screw shaft rotate in the opposite direction.

[0063] First, then, the cut mud fertilizer and seed mixture falls into the drop channel and falls along the inclined bottom into the open trench.

[0064] In general,

[0065] The present invention realizes combined operation by first breaking the soil to reduce the forward resistance of the plowshare, and then digging furrows again on the ridges, thereby achieving accurate soil covering of the sowing mixture and controlling the amount of soil covering to avoid being too deep or too shallow, thereby effectively maintaining water and fertilizer.

10. The crop seeding and fertilizing operation component of claim 9, characterized in that: The steps of fertilizer operation are as follows: Step A, storing seeds to be sown in the seeder (200) and discharging the seeds downward in a quantitative manner from a seed drop port (212); Step B, in the transfer component (201), receiving the quantitative seeds dropped from the seeder (200) at the top, and discharging and pressing the quantitative seeds downward; Step C, in the mixing component (202), first, the mud fertilizer that is continuously fed is pre-stored; then, the seeds falling from the transfer component (201) are received at the top; secondly, the mud fertilizer is squeezed and mixed with the seeds during the downward rotation; thirdly, the mud fertilizer mixed with the seeds is scraped off and falls into the falling component (203); Step D, when the seed drill moves forward, first, the lower end sheath (228) digs a ditch in the field to carry out construction work; then, the mud fertilizer mixed with seeds falls into the ditch; In step A, step AA is also performed in conjunction with the step of preparing a mixture of soil, fertilizer and water in the mud fertilizer component (204) and stirring the mixture continuously; In step C, step CC is also performed in conjunction with the step that the mud fertilizer component (204) sends the mud fertilizer mixture to the extrusion component (205); then, the extrusion component (205) rotates forward to continuously extrude the mud fertilizer into the mixing component (202); when the mud fertilizer is not needed, the extrusion component (205) rotates reversely to continuously stir the mud fertilizer; In step B, the transfer shaft body (208) rotates, firstly, receiving the falling quantitative seeds from above; then, the seeds fall to the transfer drop port (218) as the center groove (214) rotates, and fall, wherein, the protrusion of the process T key (215) acts in the straight groove of the center groove (214) through its own gravity and spring force, and the T-shaped guide block (213) shakes up and down in the radial direction of the T-shaped groove (211), so that the seeds fall without being attached; When the central groove (214) rotates upward without load, the cleaning brush (207) is driven by the cleaning shaft (206) to clean the central groove (214); In step AA, the mud fertilizer box (230) continuously stirs the mud fertilizer to prevent the mud fertilizer from condensing and separating, and the mud fertilizer is squeezed and pushed from the mud fertilizer near the shaft end to the middle optical axis through the double screw shaft (231). During this period, the mud fertilizer is pressed down by the elastically controlled n-type elastic pressure head (237), so that the mud fertilizer on the top is continuously stirred and mixed; In step C, first, the mud fertilizer enters the inner cavity of the rotating hollow shaft portion (220) through the feeding rotary joint (223) and emerges from the graduated lateral channel (222); then, as the rotating hollow shaft portion (220) rotates, when the lateral channel (222) reaches the upper position, it receives the seeds falling from the transfer drop port (218); secondly, the seeds and mud fertilizer contact the inner wall of the mixing shell (219) during rotation and sink into the mud fertilizer and mix together; thirdly, when the seeds reach the mixing drop port (224) at the lower position, due to the gravity of the mud fertilizer and the continuous squeezing force, the seeds and the mud fertilizer are exposed together; thereafter, the exposed mud fertilizer contacts the cutting plate (225) and is cut off, and the remaining mud fertilizer is squeezed and then returns to continue the cycle; In step CC, first, during the continuous conveying of mud fertilizer, the mud fertilizer falls into the extrusion box (239) through the mud fertilizer middle through hole (232); then, under the action of the rotating screw shaft (233), the mud fertilizer continuously passes through the gap between the rotating screw shaft (233) and the guide sleeve (234), and the inner cavity of the connecting seat (243), and is output from the mud fertilizer output pipe (235) and delivered to the feed rotary joint (223) through the rubber hose; When the supply of mud fertilizer is not needed, the gearbox assembly (238) is shifted to make the rotating screw shaft (233) rotate in the opposite direction; In step D, first, then, the cut mud fertilizer and seed mixture falls into the falling channel (227) and falls into the ditch along the inclined bottom (241).
