Obstacle crossing device of intelligent novel agricultural seeding machine

Abstract

The invention relates to the technical field of agricultural machinery, in particular to an obstacle crossing device of an intelligent novel agricultural seeding machine. The obstacle crossing device comprises a machine frame, a connecting rod and a furrow opener mounted at one end of the connecting rod, a kidney-shaped hole is formed in the upper surface of the machine frame, a vertically arranged cylinder is slidably mounted in the kidney-shaped hole, the upper end of the cylinder is closed, a piston is slidably mounted in the barrel, a vertically-arranged buffer rod is fixedly connected to the lower surface of the piston, the lower end of the buffer rod extends to the lower side of the barrel and is rotatably connected to the middle of the connecting rod, a vertically-arranged upper spring is arranged on the upper side of the piston, a lower spring is arranged on the lower side of the piston, the lower spring sleeves the buffer rod, and two soil cleaning pieces are symmetrically mounted on the outer surface of the lower end of the barrel. Compared with the prior art, the obstacle crossing device of the intelligent novel agricultural seeding machine has the following beneficial effect that the purpose of conveniently cleaning soil in kidney-shaped hole.

Description

technical field [0001] The invention is an obstacle-surmounting device for a smart new agricultural seeder, which belongs to the technical field of agricultural machinery. Background technique [0002] The opener is one of the key components on the seeder, and its working performance directly affects the work of the seeder. In order to prevent the rotating ditching disc or cutter head from collapsing and being damaged when encountering stones, making the whole ditching device unusable, it is necessary to install an obstacle-surpassing mechanism composed of springs and cylinders on the seeder to play The role of buffer protection. [0003] In order to prevent the cylinder from being damaged due to uneven force, the cylinder is often slid and inserted into the waist hole. However, during use, the soil entering the waist hole will adhere to the inner wall of the waist hole under the extrusion of the cylinder. As a result, the range of activities of the cylinder is reduced, an...

[0003] In order to prevent the cylinder from being damaged due to uneven force, the cylinder is often slid and inserted into the waist hole. However, during use, the soil entering the waist hole will adhere to the inner wall of the waist hole under the extrusion of the cylinder. As a result, the range of activities of the cylinder is reduced, and the soil attached to the inner surface of the waist hole needs to be cleaned frequently, which is time-consuming and laborious
