Pull-type ditching system for combined direct seed machine

Abstract

The invention belongs to the field of ditching machine tools in agricultural machineries, which is characterized in that two front plows and two rear plows are symmetrically arranged in front and back of the side plate of a seeder; the front plows are single-face turnplows, and each front plow comprises a plow standard of the front plow, a plow face of the front plow, a side plate of the front plow and a baseboard of the front plow which are welded into a whole,the side plate of the front plow and the direction of forward motion are in a line, and the plow face of the front plow deflects to the inner side of a compartment surface; each rear plow comprises a plow standard of the rear plow, a plow face of the rear plow, a soil dividing plate of the rear plate, a side plate of the rear plow and a baseboard of the rear plow which are welded into a whole, the included angle between the work curved surface of the rear plow and the direction of forward motion is 20-30 degrees; the front plows and the rear plows are fixed on a permanent seat through bolts and are welded on the side plate of the seeder; three mounting holes are reserved on the plow standards of the front plows and the plow standards of the rear plows, and the mounting height thereof is adjustable; and the curved surface element line angle of the body of the front plow is 40-45 degrees, the ratio of lead curve height h to the aperture L is 1.7-1.8, the soil-plowing angle of the turnplow blade is 25-30 degrees, and the included angle between the two tangent lines at two end points is 110-120 degrees. The invention has the advantages that the front plows suffer little resistance during the process of cutting stubbles and ditching; the rear plows can be used for removing the soil and reshaping; and the ditch patterns are orderly.

Description

technical field [0001] The invention relates to the technical field of farmland ditching equipment in agricultural machinery, in particular to a traction type ditching system of a combined live broadcast machine, and focuses on solving the problem that the ditching resistance of the combined live broadcast machine is large and the power of the tractor cannot be effectively utilized when the ditch is opened. problem, the system can also be used for ditching operations of other farm machinery. Background technique [0002] There is a lot of rain in the southern part of our country. When planting, it is generally necessary to open a box ditch every few rows for drainage or for irrigation in case of drought. There are two main methods of mechanical ditch opening operation: one is to open the ditch first and then sow. This method uses different machines to complete the ditch opening and sowing operations successively, which is time-consuming and labor-intensive, and causes repeat...

Problems solved by technology

[0003] The purpose of the present invention is to overcome the technical defects of the existing ditching machines, aiming at the problems that the power of the tractor cannot be reasonably utilized when the combined seeder is opening the ditch, and the ditching resistance is large, and the ditch type is not easy to ensure, etc., to provide a stubble breaking machine. Traction type furrowing system composed of plow before furrowing and plow after soil clearing and shaping
