Description

Soil crushing device on corn stalk stubble-burying soil-preparation ridger

Technical Field

The utility model relates to an agricultural machinery hack device especially relates to a hack device on maize straw buries 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 and stalk, thick land-dumping layer, large dry blocks of northern field soil and the like, so the corn straw has difficulty in mechanized stubble burying and field soil crushing operation. A crushing cutter in a traditional paddy field stubble burying and soil crushing device is bent into a certain angle by adopting a metal lath of about four centimeters to form an L shape. When the straw cutting machine works, the power of the tractor drives the rotating shaft to rotate, and the L-shaped transverse blade cuts into the soil, so that the straw is buried in the soil on one hand, and the soil is cut up on the other hand. However, the crushing knife in the soil crushing device is not particularly suitable for the soil crushing requirement of dry soil in northern dry fields. Because the paddy field soil has high viscosity, the soil crushing mode is mainly the cutting crushing mode, and the dry type soil is mainly the smashing crushing mode. Therefore, the soil crushing device suitable for dry soil in the northern dry field is designed, and the device has important significance for providing a good seedbed for late sowing in the northern dry field and ensuring the cultivation quality.

Disclosure of Invention

An object of the utility model is to provide a hack device on maize straw buries stubble soil preparation ridger, it makes northern dry farmland straw smash the effect better with dry field soil through the structural design of smashing the sword, and the farming quality of seedbed is better.

In order to realize the purpose, the utility model adopts the following technical scheme: a soil crushing device on a corn straw stubble-burying soil-preparation ridger comprises a rotating shaft, a plurality of connecting blocks and a plurality of crushing cutters, wherein the connecting blocks are welded on the outer diameter of the rotating shaft; the crushing cutter consists of a half cutter handle and a half cutter face; the rotation axis drive rotation through tractor power, its characterized in that:

the connecting blocks in each group are distributed in parallel at equal intervals along the length direction of the same axial center section of the rotating shaft, and the connecting blocks in the groups are uniformly distributed along the circumferential direction of the rotating shaft;

every two adjacent connecting blocks in the plurality of groups of connecting blocks are staggered equidistantly along the axial direction of the rotating shaft;

one side of the knife face of each crushing knife is provided with a cutting edge, the other side of the knife face of each crushing knife is provided with a bending corner, every two crushing knives are fixedly connected with a connecting block at the knife handle, the two crushing knives are respectively arranged on the two sides of the connecting block, and the directions of the cutting edges and the bending corners are consistent.

Further, the axial distance of the crushing cutter on the two adjacent connecting blocks in the axial direction of the rotating shaft is larger than zero and smaller than 20 mm.

Further, the thickness of the crushing knife is not less than 8 mm.

Further, the bending angle between the bending surface of the bending corner of the crushing cutter and the cutter surface is set to be 130-140 degrees.

The utility model discloses compare with traditional paddy field stubble-burying hack device, have following beneficial contribution:

1. the two crushing knives are fixed on one connecting block, not only have equidirectional blades and have certain mass, but also the mass is far away from the rotating shaft, when the rotating shaft rotates at high speed, the rotational inertia of the soil crushing device is increased, the rotational kinetic energy is increased, so that the crushing knives have the functions of crushing the field soil and smashing dry accumulated field soil, and the soil crushing effect is good;

2. the crushing cutter is provided with a bending corner, when the accumulated soil can not be crushed once, the accumulated soil can be thrown out by turning and falls on the comb teeth in the subsequent land leveling device, so that the soil blocks repeatedly enter the soil crushing device for re-crushing.

The utility model has the advantages of reasonable design, simple structure, good straw crushing and field effect, strong adaptability and the like.

Detailed Description

The invention will be further explained with reference to the drawings:

as shown in fig. 1, 2 and 3, the plurality of connecting blocks 2 are divided into a plurality of groups, the connecting blocks 2 in each group are welded on the outer diameter of the rotating shaft 1 in parallel at equal intervals along the length direction of the same axial center section of the rotating shaft 1, and the plurality of groups of connecting blocks 2 are uniformly distributed along the circumferential direction of the rotating shaft 1 and staggered at equal intervals along the axial direction of the rotating shaft 1; the crushing cutter 3 is provided with a half cutter handle and a half cutter surface, one side of the cutter surface is provided with a cutting edge 301, and the other side is provided with a bending corner 302; every two crushing cutters 3 are fixedly connected with one connecting block 2 at the cutter handles and are respectively arranged on two sides of the connecting block 2, and the cutting edges 301 of the two crushing cutters are consistent with the direction of the bending corners 302; the axial distance between the crushing cutters 3 on the two adjacent connecting blocks 2 in the axial direction of the rotating shaft 1 is set to be 15 mm; the thickness of the crushing blade 3 was set to 8 mm. The bending angle between the bending surface of the bending corner 302 and the knife surface is set to 135 °.
