Seed manure furrow opener capable of spreading manure in layers

Abstract

The invention provides a seed manure furrow opener capable of spreading manure in layers. A furrow plough shovel is fixedly arranged on the front wall at the lower end of a column, and seed protection plates are located below a scoop-wheel seed-metering device and fixedly arranged on the lateral wall opposite to the column. The seed manure furrow opener is characterized in that the bottom of the seed protection plates is 50-80mm higher than the bottom of the column. A bottom plate is welded at one end of the bottom of each seed protection plate close to the column, a front scraping plate is respectively fixedly arranged on each bottom plate, and the front scraping plates and the seed protection plates form a 120-degree inclination angle. Two back scarping plates are hinged to the outer side of the seed protection plates through pin shafts. The top of the column is connected with a manure distribution pipe, one side at the lower end of the column far away from the furrow plough shovel is beveled, an anti-blocking slide carriage is welded at the lower end in the column, and the anti-blocking slide carriage and the beveled surface form a lower manure discharge port. An upper manure discharge port is arranged on the column at the position with 30-50mm away from the upper end of the lower manure discharge port, a manure distribution plate is additionally arranged at the lower edge of the upper manure discharge port in the column, and the manure distribution plate and the anti-blocking slide carriage incline in the same direction; and the bottom edges of the front scraping plate are level to the lower edges of the upper manure discharge port. The seed manure furrow opener saves energy consumption and production cost and can effectively reduce straw blocking during seed sowing.

Description

technical field [0001] The invention relates to a seed fertilizer ditch opener capable of layered fertilization, which belongs to the technical field of agricultural machinery. Background technique [0002] The opener is an important part of the seeder. It is responsible for introducing fertilizer and seeds into the soil to a specified depth and covering the soil. Its sowing and fertilizer discharge of the common seeder require two openers to operate respectively. The fertilization opener is installed before the sowing opener, so that the distance between the two openers for sowing and fertilizing on the no-tillage planter is very close, which not only consumes high power, but also increases the material consumption and production cost of the planter, and is easy to produce The congestion of straw and weeds seriously affects the quality of sowing.
