Description

V-groove fertilizing, pesticide spraying and film covering seeder Technical Field The invention relates to the field of agricultural machinery, in particular to a V-ditch fertilization, pesticide spraying and film covering seeder. Background The seeder is an agricultural machine for sowing seeds into soil, can replace manual sowing, and improves the working efficiency and the sowing uniformity. For field crops such as corn, a film-covered sowing technology is often adopted for the purposes of preserving water and soil moisture, improving ground temperature and inhibiting weed growth. The V-shaped ditch film-covered sowing is a planting mode that a plastic film is covered above a V-shaped ditch and seeds are sowed at the bottom of the ditch, and has good water-collecting drought-resisting effect. The existing V-groove fertilizing, pesticide spraying and film covering seeder comprises a fertilizing device, a pesticide spraying device, a V-groove forming device, a film covering device, a film edge soil covering device and a hole sowing device, wherein the hole sowing device is required to punch holes on mulching films corresponding to the bottoms of V-shaped grooves and to sow seeds into soil during final sowing. In the operation flow, the hill-drop planter is a key component for realizing accurate sowing. The existing hill-drop planter mostly adopts a roller-type hill-drop planter, a plurality of duckbilled hole-forming devices are uniformly arranged on the circumference of the roller, and a seed sowing mechanism is arranged inside the roller. During operation, the roller contacts with the mulching film and passively rotates along with the advancing of the seeder, in the rotating process of the roller, the seed sowing mechanism conveys seeds to the duckbill hole forming device one by one, when the duckbill hole forming device rotates to the lowest position, the duckbill is opened, and the seeds fall into seed holes to finish one-time sowing. The structure is driven by the friction force of the roller and the mulching film, does not need external power input, and has the advantages of simple structure and automatic synchronization of plant spacing and advancing speed. When the hill planter is used for hill sowing, the seed taking mode is various, but the negative pressure induced draft seed taking is one of the core technologies in the precision hill sowing device, the working principle is that a fan is utilized to generate negative pressure on the suction hole side of the seed sowing disc, seeds are adsorbed and carried to a seed dropping area one by one, and then the seeds are dropped by dead weight by removing the negative pressure or setting positive pressure seed cleaning. However, the conventional drum-type hill planter still has the defects that the first sowing precision is not high, although one seed can be accurately taken by negative pressure induced draft seed taking under most conditions, two or more seeds can be sometimes taken, so that two or more seeds fall into one seed cavity to cause seed waste and difficult seedling in a later period, or no seeds exist in the seed cavity due to the blockage of a seed sowing channel, the failure of the seeds to timely enter duckbilled and the like, and the crop yield is influenced. Secondly, lack real-time monitoring and feedback, the driver is difficult to find the miss-seeding problem in time, and the manual reseeding can only be performed after the operation, and time and labor are wasted. Disclosure of Invention The invention aims to overcome the defects of the prior art and provides a V-ditch fertilization, pesticide spraying and film covering seeder. The technical scheme adopted by the invention is as follows in order to solve the technical problems: A V-ditch fertilizing, spraying and film covering seeder comprises a frame, a fertilizing device, a spraying device, a V-ditch forming device, a film covering device, a soil covering device and a hill seeding device; the hill-drop device comprises a connecting frame, a seed box, a hollow fixed shaft, a first fan, a second fan, an inner annular baffle plate with a first notch and a first inner through hole, an outer annular baffle plate with a first outer through hole, a first connecting hard tube connected with the first inner through hole and the first outer through hole, and a travelling wheel, wherein the first fan is connected with a blowing tube part inserted into one end of the fixed shaft, the second fan is connected with an air suction tube part inserted into the other end of the fixed shaft, the travelling wheel comprises two outer circular plates, two inner circular plates, a plurality of wheel spokes and a plurality of duck-bill parts, the duck-bill parts comprise a mounting plate connected with the two outer circular plates, a seed storage shell fixed on the mounting plate, a box cover connected with the box cover through an elastic reset connecting part, an abutting plate fixed on the mounting
