Description

Multifunctional integrated seeder Technical Field The invention relates to the technical field of seeders, in particular to a multifunctional integrated seeder. Background Sowing is used as a key link of crop planting, and the operation quality directly influences the emergence rate, the growth consistency and the final yield of subsequent crops. The existing seeding equipment is difficult to comprehensively adapt to complex and fine planting requirements, and still has a plurality of defects. Firstly, traditional seeding equipment only possesses single seed metering function more, and often need accomplish a plurality of links such as arable land, ditching, seeding, fertilization, earthing, suppression in proper order in the crop seeding process, and the peasant household need be equipped with multiple agricultural machinery equipment such as rotary cultivator, seeder, fertilizer distributor, has not only increased equipment acquisition cost and storage pressure, and field operation process is loaded down with trivial details, many times advances the ground moreover, has reduced operating efficiency. Secondly, the farmland in China is complex in type, most plots are influenced by factors such as topography, irrigation, cultivation history and the like except for high-standard farmland in part of plain areas, and the problems of fluctuation of the farmland, local concave or convex and the like exist. The seeding mechanism of the existing seeder is designed to be at a fixed height, and lacks flexible self-adaptive adjusting function, when the device works on uneven field, the relative height of the seeding mechanism and the field can fluctuate along with the change of terrain, and further the seeding depth is neglected and shallow, the consistency of the seeding depth is poor, and the quality of the seedlings is uneven. When the seed is too deep, the oxygen and illumination required by seed germination are insufficient, the ground breaking resistance is high, the situations of delayed emergence, weak emergence and even no emergence are easy to occur, when the seed is too shallow, the seed is easily influenced by drought and insect damage, the root system is shallow in soil, the later lodging resistance is poor, and finally, the field crops are uneven in emergence, the growth situation difference is large, and the improvement of the crop yield is severely restricted. Disclosure of Invention The invention aims to provide a multifunctional integrated seeder which integrates various functions of farmland, ditching, seeding, fertilization, earthing, compacting and the like into a whole, and remarkably improves the seeding efficiency of crops, and the multifunctional integrated seeder has a self-adaptive adjusting function, a seeding mechanism of the multifunctional integrated seeder can automatically adjust the height according to the conditions of fluctuation, local depression or protrusion and the like of a field surface, ensures the relative height stability of the seeding mechanism and the field surface, ensures the uniform and consistent seeding depth, effectively improves the seedling emergence quality, avoids the problems of seedling emergence delay, weak seedling, no seedling emergence, poor lodging resistance and the like caused by improper seeding depth, and remarkably improves the yield of crops. The technical scheme adopted by the invention for solving the technical problems is that the multifunctional integrated seeder comprises a frame, wherein the frame comprises a front frame and a rear frame, the rear frame comprises an upper frame and a lower frame, one end of the upper frame is fixedly connected with the front frame, the other end of the upper frame is movably connected with the upper part of an adjusting mechanism, one end of the lower frame is movably connected with the front frame, and the other end of the lower frame is movably connected with the lower part of the adjusting mechanism; The rotary tillage mechanism is connected with the front frame; the fertilizing mechanism is connected with the front frame and is positioned above the rotary tillage mechanism; the seeding mechanism is connected with the lower rack through a first connecting rod and comprises a plurality of sowers and a first connecting seat for fixing the sowers, and the first connecting seat is movably connected with the first connecting rod; the pressing mechanism is connected with the lower frame through a second connecting rod and comprises a plurality of pressing wheels and a second connecting seat for fixing the pressing wheels, the pressing wheels are correspondingly arranged with the seeder, and the second connecting seat is movably connected with the second connecting rod; the ditching mechanism is positioned at two sides of the frame. Further, fertilizer distributor includes fertilizer case and carries auger, the bottom of fertilizer case be provided with the recess that fertilizer case length direction is unanimou
