Background technology
The cereal crops such as greengrocery crop and Oryza sativa L. such as Citrullus vulgaris, Fructus Capsici, Fructus Lycopersici esculenti are both needed to carry out seedling operation, traditional seedling operation is all vegetable or cereal crops seed points are placed in hole, hole tray cave by artificial hand point mode, and working performance is low, operation quality is poor, labor intensity is greatly the problem that must solve. In recent years, a kind of negative pressure is inhaled kind of a hole tray implanted device and is applied in production operation, and compared with traditional artificial hand bunch plating, labor intensity reduces, and working performance and operation quality increase. But, due to the deficiency of structural design, this machine adopts negative pressure to inhale and plants, it unloads kind of an operation is after laying down negative-pressure sucking, only relies on the deadweight of kind of grain and falls to broadcasting from suction nozzle and execute in hole tray cave is cheated, finds in operation uses, the kind grain card having more than 1% is stayed suction nozzle and is unloaded, unload kind of rate below 98%, simultaneously as contain kind of a dish transfixion, the seed-filling rate < 70% of suction nozzle, heavily kind rate > 20%, hole rate and replay rate are high, cause seeding quality to decline.
Summary of the invention
The purpose of the invention is aiming at above-mentioned prior art Problems existing, and a kind of vibration negative pressure suction kind of design unloads kind of a combination tray seeder with malleation, reaches to improve seed-filling rate and unloads kind of a rate, reduces replay rate, ensures the purpose of seeding operation quality.
The purpose of the invention is achieved in that and is respectively mounted hole tray on support assembly, blower fan and the normally opened air valve of negative pressure, the transposition rotating hinge of rocking bar is contained on support assembly, be hinged equipped gas dish in described transposition rocking bar top ends, handle and suction nozzle are fitted respectively over the upper of gas dish, on following side, described support assembly is also respectively mounted the normally closed air valve of malleation and vibrator, on described vibrator upper lateral part, it is positioned at hole tray sidepiece place and a Sheng kind dish is installed, described gas dish is by a left side for the rocking bar that replaces, the parallel swing of dextrad cooperates with hole tray and a Sheng kind dish respectively, the two ends of negative pressure trachea are connected with threeway and fan air inlet respectively, the normally opened air valve of described negative pressure is fitted on negative pressure trachea pipeline, the two ends of malleation trachea are connected with threeway and blower fan gas outlet respectively, the normally closed air valve of malleation is fitted on malleation trachea pipeline, described gas dish is connected by main trachea with threeway, described gas dish and the normally closed air valve of malleation, the normally opened air valve of negative pressure coordinates in synchronizing contact or synchronizes to disengage cooperation, so far constitute vibration negative pressure suction kind and unload kind of a combination tray seeder with malleation.
The invention adopts vibration negative pressure suction kind and malleation to unload kind of a combinative structure, the seed-filling rate of suction nozzle is greatly improved and unloads kind of a rate, reduce the heavily kind rate of suction nozzle simultaneously, have novel structure, rationally, simple, Job Operations simple and convenient, use the feature reliable, operation quality is good, efficiency is high, can be widely used for all kinds of vegetable and cereal crops seedling operation uses, applied widely.
