Anti-blockage corn no-tillage seeder

Abstract

The invention relates to an anti-blockage corn no-tillage seeder, which comprises a machine frame, a fertilizer tank, a plurality of no-tillage seeder single bodies and ground wheels. The fertilizer tank and the plurality of no-tillage seeder single bodies are arranged on the machine frame. The fertilizer tank is provided with a fertilizing shaft which is connected with the ground wheels by chain transmission. Each no-tillage seeder single body comprises a seeding box and a furrowing blade handle, which are arranged on the machine frame, wherein the bottom of the furrowing blade handle is connected with a fertilizing furrower; and a seeding furrower and a press wheel are connected with the machine frame at the rear side of each fertilizing furrower. The anti-blockage corn no-tillage seeder is characterized in that: a driving shaft parallel to the fertilizing shaft is connected below the machine frame and in front of the furrowing blade handles by a plurality of supporting frames; one end of the driving shaft is connected with the fertilizing shaft through chain transmission; the driving shaft is provided with driving bevel gears corresponding to the no-tillage seeder single bodies; the centers of driven bevel gears meshed with the driving bevel gears are fixedly connected with roller shafts; each roller shaft is provided with a roller for pushing straw aside; and the lower ends of the roller shafts are connected with the fertilizing furrowers rotationally.

Description

technical field [0001] The invention relates to an agricultural machine, in particular to a corn no-tillage seeder with an anti-blocking function. Background technique [0002] Since conservation tillage can reduce wind erosion and water erosion, and improve soil fertility and drought resistance, my country has vigorously promoted conservation tillage for decades. The difference between conservation tillage and traditional tillage is that it directly sows on the land covered with straw, so no-tillage sowing technology is the key. [0003] There are many kinds of no-tillage seeders currently in use. From the principle of anti-blocking function, the main points are: (1) Install a passive stubble cutting device in front of the opener: a typical curved surface type seeder developed by the former Beijing Agricultural Engineering University. Grass cutter, which has good grass separation performance, simple structure, low cost, and is not easy to wear, but has poor adaptability to...

Problems solved by technology

[0003] There are many kinds of no-tillage seeders currently in use. From the principle of anti-blocking function, the main points are: (1) Install a passive stubble cutting device in front of the opener: a typical curved surface type seeder developed by the former Beijing Agricultural Engineering University. Grass cutter, which has good grass separation performance, simple structure, low cost, and is not easy to wear, but has poor adaptability to the amount of straw coverage; the combined depth-limiting grass cutter and inter-row grass roller developed by China Agricultural University, the effect of the combination of the two better, but it is still difficult to avoid clogging when the amount of straw coverage is large; therefore, this type of anti-blocking device has poor adaptability, and it is difficult to solve the problem of blockage when the amount of straw coverage is large

(2) Power-driven active anti-blocking device: A typical example is the drive-type disc knife anti-blocking device developed by China Agricultural University. The disc knife in this device obtains a higher cutting speed and can effectively use sliding cutting to Good cutting effect; the strip crushing planter produced by Hebei Nonghaha uses the principle of crushing to open the way and directional weeding to complete the sowing while cutting the straw; but the power consumption of the above active anti-blocking device is too large, due to the high speed, Causes strong vibration of the machine tool, poor safety, and the problem of dust caused by high speed during operation is also very prominent

(3) Multi-beam structure: The openers are staggered and installed on the multi-beams to increase the distance between the openers. Wider row spacing can increase the passage of straw and reduce the problem of stubble blockage. Adopt traction type; this mechanism is not suitable for the current situation of small plots and low tractor power in our country
