Wheat tillage limiting sowing machine

Abstract

The invention provides a wheat tillage limiting sowing machine, comprising a tillage limiting device, a ridge forming device, a trenching sowing device, a compacting machine and a rack, wherein the tillage limiting device is used for deep tillage of a sown part, and comprises two groups of crankshafts, a connecting rod, a tillage limiting rod and a shovel, and the ridge forming device adopts upper layer of dry soil for ridge forming. When tillage is carried out, each group of crankshafts drives the corresponding shovel to vertically move for deep tillage through the corresponding connecting rod and the corresponding tillage limiting rod, then a shovel of the ridge forming device makes arc-shaped movement downwards to sow the upper layer of dry soil into a ridge forming transmitter for ridge forming under the action of the crankshafts, the connecting rod and a ridge forming rod, and afterwards the trenching sowing device and the compacting machine are used. According to the wheat tillage limiting sowing machine, the front of each wheat trenching sowing device is provided with one shovel of the ridge forming device and one shovel of the tillage limiting device, and only after the soil at the sown parts is subjected to deep scarification and the upper layer of dry soil is removed for ridge forming, trenching fertilizer application, sowing and compacting can be carried out.

Description

technical field [0001] The invention relates to a limited-tillage wheat planter which only deeply plows the sowing place and uses the upper layer of dry soil to inject ridges, and belongs to the technical field of agricultural machinery. Background technique [0002] Existing wheat planters plow the land first and then sow, and some have proposed no-tillage sowing, such as patent No. 201110045864.1 wheat no-tillage planter, including blades for breaking stubble in furrows, ditch openers for sowing, suppression devices and machines. frame, this technology basically does not disturb the soil layer; and it can cut off the straw of weeds, and it is not easy to drag the grass. However, the trenching and stubble breaking in this technology is a kind of shallower cultivated land. Because there is too little loose soil, it is difficult to form ridges, which will increase the difficulty of watering wheat in the future. After sowing with this seeder for many years, a shallower cultiva...

Problems solved by technology

However, the trenching and stubble breaking in this technology is a kind of shallower cultivated land. Because there is too little loose soil, it is difficult to form ridges, which will increase the difficulty of watering wheat in the future. After sowing with this seeder for many years, a shallower cultivated land will be formed. The bottom of the plow is bound to reduce the yield of wheat
