Micro corn sowing fertilizing and mulching machine

Abstract

The invention discloses a micro corn sowing fertilizing and mulching machine which comprises a traction frame, two web wheels and a transmission mechanism, a plant distance regulator, two furrow plough tips and a seeding fertilizer and a transmission mechanism, a set of film mulcher frames, a film mulcher shaft, a set of film mulcher lifting mechanism, two film pressing wheels and a width regulating shaft, and two soil covering wheel disk mechanisms; the front of the traction frame is hinged with the tiller body; the two ends of the two fertilizer sowing device drive shafts respectively penetrate through the hexagonal holes in the middle of the middle sprocket room active sprocket and the seeding tray; the right side sprocket of the plant spacing regulator is connected to the drive shaft of the two seeding fertilizers by a chain near the central fixed sprocket; the front part of the film mulcher lifting mechanism is hinged on the tail support fork of the traction frame, and the rear part is sleeved on the laminating sleeve shaft. The machine of the invention is driven by a micro tillage machine and driven by a rotary tiller. After the tiller is finished, there is no need to replacethe iron wheel. Only the cultivating knife box and the resistance cultivating knife are taken off, and then the pin hole of the front end of the traction frame of the machine is hinged with the microtillage machine to start the seeding and fertilizing filming operation.

Description

technical field [0001] The invention relates to agricultural machinery, in particular to a miniature corn sowing, fertilizing and film covering machine. Background technique [0002] Sowing corn in the northern plains has gradually transitioned from manual labor to mechanized operations. In the hilly and mountainous areas of the south, large and medium-sized seeders cannot be used. The labor intensity of the manual seeder operator is high, and the work efficiency is too low. The planter driven by the small four-wheel tractor has a complex structure, inconvenient loading and unloading and operation, the labor intensity of the operator is high, and the purchase cost remains high, so it has not been widely used. [0003] At present, only some of the seeding machines suitable for micro-tillage machines are developed by some agricultural science institutes and research institutes. The seeders are transplanted from large and medium-sized seeders, and there are problems such as dr...

AI Technical Summary

Problems solved by technology

Seeders driven by small four-wheel tractors have complex structures, are inconvenient to load, disassemble and operate, and the labor intensity of operators is high, and the purchase cost remains high, so they have not been widely used.

[0003] At present, only some of the seeding machines suitable for micro-tillage machines are developed by some agricultural science institutes and research institutes. The seeders are transplanted from large and medium-sized seeders, and there are problems such as driving iron wheels sticking to mud and slipping, and ground wheel webs. The clay slips, the structure of the seeder is irreversible in one direction, and the row spacing is not variable. It can only realize a single function of sowing, the function of adjusting the depth of sowing is not available, the function of adapting to uneven ground is not available, and the structure is bulky.
