Grass entangling preventing wide-width row sowing machine

Abstract

The invention discloses a grass entangling preventing wide-width row sowing machine. The grass entangling preventing wide-width row sowing machine comprises an elbow and an outlet pipe. The elbow is divided into two sections, one section is in a strip shape, and the other section is in an arc shape. The outlet pipe is in a flat trapezoid shape, and the upper port of the outlet pipe is smaller than the lower port of the outlet pipe. The port of the arc-shaped section of the elbow is inserted into the upper port of the outlet pipe. The bending direction of the grass entangling preventing wide-width row sowing machine is opposite to the forwarding direction of a tractor, so that the grass entangling preventing wide-width row sowing machine is not entangled by straw; meanwhile, certain distance is kept between the lower end of the grass entangling preventing wide-width row sowing machine and the ground surface, it is guaranteed that the grass entangling preventing wide-width row sowing machine does not hook straw below the ground plane, and sowing efficiency is improved; the sowing width of the grass entangling preventing wide-width row sowing machine is larger than that of a duckbill type row sowing machine and the like, so that the sowing line spacing is increased, photosynthesis of plants is facilitated, the tillering conditions of the plants are increased, and production and income are increased.

Description

technical field [0001] The invention belongs to the field of farmland plowing and sowing machinery parts, in particular to a wide-width seed drill for preventing entanglement of grass. Background technique [0002] With the continuous development and progress of agricultural planting technology, the sowing of dry crops such as wheat has shifted from manual operation to mechanized operation. At present, the more advanced sowing method is mechanized row sowing. At the same time, due to the rotation of the ground, the sprocket and chain drive the grooved wheel in the seed box at the lower end of the seed box to rotate, and the grooved wheel discharges the seeds to the seeding pipe, and then flows to the seed drill (also known as rowing) through the seeding pipe. The current seed drills mainly include duckbill type, shovel point type, chisel type, etc., but no matter what type, the seed outlet is bent towards the direction of the tractor, so that the weed straw will inevitably ...

Problems solved by technology

[0003] At the same time, the current drills are all round or square tubes, and the seeds flowing out are in a linear shape, which we call narrow drills. The land utilization rate of farmland is not high, and the yield of farmland is low, which affects the income level of farmers.
