Referring to fig. 2, fig. 2 is a schematic structural diagram of a pressure adjusting mechanism 2 according to an embodiment of the present invention. The four-bar linkage profiling mechanism 21 of this embodiment includes a seeding monomer link 213 and an upper link 211 and a lower link 212 that are provided in pairs, both ends of the upper link 211 are connected with the upper end of the seeding monomer link 213 and the machine body 1 respectively, both ends of the lower link 212 are connected with the lower end of the seeding monomer link 213 and the machine body 1 respectively, and the upper link 211 and the lower link 212 are arranged in parallel. The lower pressure regulator 22 can adopt any one of a hydraulic oil cylinder, a pneumatic spring or an air bag to realize the adjustment of the lower pressure, a lower pressure sensor 221 is arranged on the lower pressure regulator 22 and used for recording the pressure value of the lower pressure regulator 22, and the pressure value range of the lower pressure regulator 22 is 0-4000N. Wherein, the upper connecting rod 211 and the lower connecting rod 212 are respectively provided with two, the seeding monomer link span 213 is fixedly connected with the seeder frame, one end of the upper connecting rod 211 is hinged with the seeding monomer link span 213 through an upper pin shaft 25, the other end of the upper connecting rod 211 is hinged with the seeder body 1 through another upper pin shaft 25, one end of the lower connecting rod 212 is hinged with the seeding monomer link span 213 through a lower pin shaft 26, the other end of the lower connecting rod 212 is hinged with the seeder body 1 through another lower pin shaft 26, the whole seeding monomer can rotate around the upper pin shaft 25 and the lower pin shaft 26 at one end of the upper connecting rod 211 and the lower connecting rod 212, and monomer profiling is realized.
In this embodiment, the lower pressure regulator 22 is preferably a hydraulic cylinder, one end of the hydraulic cylinder is connected to the upper link 211 through an upper mounting seat 23, the other end of the hydraulic cylinder is connected to the lower link 212 through a lower mounting seat 24, an oil inlet 222 of the hydraulic cylinder is disposed on the upper mounting seat 23, and the lower pressure regulator 22 is mounted at the oil inlet 222. One end of the hydraulic oil cylinder is mounted on the upper mounting base 23, two ends of the upper mounting base 23 are respectively and fixedly connected with the pair of upper connecting rods 211, the other end of the hydraulic oil cylinder is mounted on the lower mounting base 24, and two ends of the lower mounting base 24 are respectively and fixedly connected with the pair of lower connecting rods 212.
When the lower pressure regulator 22 is a hydraulic cylinder, the hydraulic oil supply is from the tractor or tractor hydraulic system, and when the lower pressure is increased, the oil supply is increased by the oil delivery pump, the hydraulic oil enters the hydraulic cylinder through the oil inlet 222, and the piston rod is extended. A lower pressure sensor 221 is installed at the oil inlet 222 to record the pressure value of the lower pressure regulator 22. Because the upper part of the hydraulic oil cylinder is fixedly connected with the upper connecting rod 211 through the upper mounting seat 23, the downward pressure is increased, when the oil cylinder extends, the downward pressure acts on the two lower connecting rods 212 fixedly connected with the lower mounting seat 24, so that the whole machine body 1 together with the components thereon rotates clockwise around the upper pin shaft 25 and the lower pin shaft 26 hinged with the seeding monomer connecting frame 213.

If the adjusting handle 31 is rotated to enable the adjusting screw rod 32 to retract backwards, the connecting block 33 is driven to move anticlockwise, the depth limiting block 35 is driven to press the depth limiting crank arm 36 downwards, the depth limiting wheel 5 is lifted, the sowing depth becomes shallow, and similarly, the depth can be reversely adjusted to enable the sowing depth to become deep.
Referring to fig. 4-5, fig. 4 and 5 are schematic diagrams of the operation of the present invention, respectively. The utility model discloses it is difficult to control to the seeder is broadcast dark uniformity, influence the production problem of seeding quality, use the difference in height between gauge wheel 5 and the disc furrow opener 4 to broadcast dark L0 for the ideal, through exerting certain effort on gauge wheel 5, carry out compaction effect to not pressing soil 83, disc furrow opener 4 leaves the stable 8 lateral walls 81 in kind ditch of both sides, neat when 8 lateral walls 81 in kind ditch, the nothing is collapsed, and during no backward flow soil 84 in two kinds of 8 lateral walls 81 in kind ditch, seed 7 is under the effect of seed guide pipe, accurately broadcast kind ditch 8, the position of seed 7 this moment is located kind ditch 8 bottoms, the depth of planting is for the ideal depth of planting L0. Namely, the side wall 81 of the seed ditch 8 of the furrow opener is stable through the compacted soil 82 by controlling the combined action of the furrow opener and the depth-limiting wheel 5, and the soil 84 without collapse and backflow is ensured to stably broadcast deeply the seeds 7. Depth wheel 5 has the compaction effect to soil under certain effort, cuts soil when disc furrow opener 4 during operation, and the 8 lateral walls 81 of seed ditch that form are neat, do not have and collapse, and during the no backward flow soil 84 in the both sides wall 81, seed 7 is under the effect of seed guide pipe, and the seed ditch 8 is broadcast to the accuracy, and the position of seed 7 this moment is located 8 bottoms of seed ditch, and the back is again through earthing and suppression operation, accomplishes the seeding, and the seeding depth this moment is promptly for ideal depth of broadcast L0. If exert during the downforce or the action of gravity on gauge wheel 5 are not enough, 8 lateral walls 81 of seed furrow that disc furrow opener 4 cut soil formation are unstable, can take place to collapse, under disc furrow opener 4 pivoted effect, can cause 8 unilateral walls 81 of seed furrow or 8 both sides walls 81 of seed furrow to take place the backward flow phenomenon, when there is backward flow soil 84 in the seed furrow 8, the seed 7 degree of depth of sowing into seed furrow 8 through the seed guiding pipe again can change, and the actual depth of sowing L1 can be less than ideal depth of sowing L0. Under the same soil type condition, the larger the acting force exerted on the depth wheel 5, the more stable the side wall 81 of the seed trench 8, the larger the sinking amount of the depth wheel 5 relative to the ground 9, and the larger the volume weight of the soil below the depth wheel 5. Under the stable condition of seed furrow 8 lateral wall 81, the effort of applying on gauge wheel 5 should not too big, prevents to excessively densify soil, influences seed 7 development emergence and root system growth.
Of course, the present invention can be embodied in many other forms without departing from the spirit or essential attributes thereof, and it is intended that all such modifications and variations be considered within the spirit or scope of the present invention as defined by the appended claims.
