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

Embodiment Construction
[0011] The purpose of the present invention is achieved like this: the support of this wheat limited tillage planter links to each other with the tractor, the gearbox above the support links to each other with the output shaft of the tractor, The crankshaft and the wheel are connected, and the tillage limiting lever crankshaft and crankshaft drive the shovel to move up and down through the tillage limiting lever to deeply plow the sowing place, and bring the soil to the top of the tillage limiting leveler bracket. There is a screw shaft on the bracket, and the two sides of the screw shaft There is a transmission wheel, and the transmission wheel is connected with the crankshaft wheel. Through the rotation of the screw shaft, the soil is crushed and evenly covered by the half-moon groove under the leveling bracket on the top of the tea crop straw returned to the field on both sides of the shovel, and then driven to the top. The ditching helical rotation of the spiral opener will...

The invention provides a wheat tillage limit sowing machine which comprises a tillage limit machine, a ridging device, ditching sowing devices, a compacting machine and a frame. The tillage limit machine is used for deeply tilling a sowing position, the ridging device for ridging by upper dry soil, and the tillage limit machine comprises two groups of crank shafts, a connecting rod, a tillage limit rod and shovels. When the sowing machine is used for tilling, the crank shafts drive the shovels to vertically move through the connecting rod and the tillage limit rod to deeply till the soil, arc-shaped downward moving of the shovels of the ridging device is implemented under the actions of crank shaft connecting rods and ridging rods, the upper dry soil is added into a ridging conveyer to ridge, and operations of the ditching sowing devices and the compacting machine are implemented. According to the sowing machine, one group of shovels of the ridging device and the tillage limit machineare arranged in the front of each group of wheat ditching sowing device, the soil at the sowing position is deeply loosened, the upper dry soil is removed, and ditching, fertilizer applying, sowing and compacting can be implemented after ridges are formed.
Description
technical field [0001] The invention relates to a kind of wheat that is only deeply plowed at the sowing place, and the excess soil after loosening the soil is uniformly covered on the tea crop stalks returned to the field and leveled, and the upper layer of dry soil is used for ridge injection The utility model relates to a limited-tillage seeder, which 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. This technology basically does not disturb the soil layer; and it can cut off the weed stalks and 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, i...
