Description
Technical Field
The utility model relates to an agricultural machinery buries the stubble device, especially relates to a corn stalk buries stubble device on stubble soil preparation ridger, belongs to agricultural machine manufacturing and designing technical field.
Background
In the circular operation of planting corns in large areas in dry land in northern China, the mechanized returning of corn straws to the field is an important farming project. The corn straw has the characteristics of thick stubble height, thick inverted-ground layer laying and the like, so the mechanical stubble burying and smashing operation is difficult. The traditional paddy field stubble burying device is not suitable for the requirement of smashing and burying the stubble of the corn straw in the dry farmland, so people design a paddy field corn straw stubble burying device, a plurality of stubble burying blades are fixed on a rotating shaft by the device, and the stubble burying blades are bent into a certain angle by adopting metal laths of about four centimeters to form an L shape. When the corn stubble burying machine works, the power of a tractor drives the rotating shaft to rotate, and the L-shaped transverse blade crushes and embeds corn straw into soil to bury stubbles. However, in practical application, because the transverse blades and the corn straws are mostly in a cross contact mode and the contact surface is small, the traditional corn straw stubble burying device for the dry farmland is mainly used for crushing and secondarily used for burying the corn straws, and the effect of burying the corn straws is poor.
Disclosure of Invention
In order to overcome the technical insufficiency of the stubble device of current dry land corn stalk burying, the utility model provides a corn stalk buries stubble device on the stubble soil preparation ridger, it reaches the purpose that improves the stubble effect of burying through the structural design of pivot and handle of a knife, handle of a knife and blade.
In order to achieve the above purpose, the utility model adopts the following technical scheme: a stubble burying device on a corn straw stubble burying soil preparation ridger comprises: the stubble burying machine comprises a rotating shaft, a plurality of connecting discs and a plurality of stubble burying knives, wherein the rotating shaft is driven to rotate by the power of a tractor; the stubble burying cutter consists of a cutter handle and a blade, wherein the cutter handle is made by bending a metal lath into a set angle, and is characterized in that:
the connecting discs are fixed on the rotating shaft at intervals;
one end of each of four cutter handles is connected with the connecting disc and is uniformly distributed along the circumference of the connecting disc, and the bending angle between every two adjacent cutter handles is left and right;
the blade is a combination of a rectangular rectangle and an isosceles triangle, and the bottom edge of the isosceles triangle is the long edge of the rectangular rectangle;
the blade is fixedly connected to the other end of the hilt;
the tool holders on two adjacent connecting discs in the rotating shaft are mutually staggered by 45 degrees along the circumferential direction, and the distance between the blade on the left-bent tool holder of one connecting disc and the blade on the right-bent tool holder of the adjacent connecting disc in the axial direction of the rotating shaft is equal to zero;
the intersection angle of the bottom edge of the isosceles triangle on the blade and the axial center section of the rotating shaft is set between 14 degrees and 18 degrees.
Furthermore, the plate surface of the metal lath of the knife handle is vertical to the axial center section of the rotating shaft, and the rear end of the knife handle is wide and the front end of the knife handle is narrow.
Furthermore, the blades are provided with cutting edges on two sides of the isosceles triangle.
Further, the blade face of the blade is perpendicular to the plate face of the metal lath.
The utility model discloses compare with traditional dry farmland maize straw stubble-burying device, have following beneficial contribution:
1. the contact area with the corn straws is large, and no axial distance is left on the path of treading the straws;
2. the straw crushing and the straw embedding are carried out simultaneously, and the double effects are obvious.
The utility model has the advantages of reasonable design, simple structure and good stubble breaking and burying effects.
