Line centering no-tillage sowing machine for wheat in farmland covered by corn stalk

Abstract

A non-ploughing sower of wheat for the field covered by corn stalks aimes at performing collecting corn stals, cutting, ditching, applying fertilizer, sowing and rolling, and is composed of power drive system, knife axle, stalk collector installed in the front of machine frame, and knives installed to knife axle. Its advantages are less earthwork, low power consumption and no pollution of corn stalks.

Description

technical field [0001] The invention belongs to the technical field of agricultural machinery, in particular to a corn stalk-covered wheat row no-tillage seeder used in conjunction with a tractor. Background technique [0002] At present, in North China, including Beijing, Tianjin, Shandong, Hebei, Shanxi, Henan and other places, the governments of various places have paid attention to conservation tillage and are actively promoting conservation tillage technology. However, the biggest problem is that after corn stalks are harvested, corn stalks are thick and tough, and it requires a lot of power to chop them up when sowing wheat in corn stalk-covered land without tillage. Moreover, the amount of corn stalks is large and easily entangled on the planter. Straw plugs are formed.

However, the biggest problem is that after corn stalks are harvested, corn stalks are thick and tough, and it requires a lot of power to chop them up when sowing wheat in corn stalk-covered land without tillage. Moreover, the amount of corn stalks is large and easily entangled on the planter. Straw plug

[0003] To solve this problem, there are currently two solutions: the first method is to crush the corn stalks with a straw grinder, and then use a disc harrow or a rotary tiller to bury the crushed straw underground to reduce the amount of straw on the surface. , and then prepare the land and sow with an ordinary wheat seeder. Although this method does not require plowing, after the corn is harvested, the straw needs to be crushed, harrowed, prepared, and then sown. The tractor needs to enter the land at least 4 times, and the operation cost is high. , the agricultural time required for wheat sowing after corn harvest is longer, which cannot meet the needs of timely sowing: the second method works on the principle that after corn harvest, no other operations are required, such as the invention patent ZL99126557.2 "straw strip cutting Crushed tillage seeder", directly use this machine to enter the ground. The machetes and straight knives on the cutter shaft of this seeder are installed at intervals in strips. Chopped and mashed to form a relatively clean strip, followed by openers for re-furrowing and seeding

The advantage of this method is that after the corn is harvested, it can be directly sown without any work, but the biggest disadvantage is that because the knife on the knife shaft needs to penetrate into the soil and break the soil during work, it consumes a lot of power and it is difficult to improve the work efficiency. , and the broken soil is easy to cause water loss
