Abstract
The invention relates to agricultural machines, in particular to a corn harvester. The corn harvester comprises a front cornstalk gathering device, a corncob picking device and a stalk smashing device, wherein the smashing device comprises a cutter shaft connected with cutting-off cutters. The corn harvester is characterized in that cutter shaft threaded holes used for installing the cutting-off cutters are formed in the cutter shaft, the cutting-off cutters are of a long-strip-shaped structure, each cutting-off cutter is provided with a cutting-off cutter threaded hole matched with the cutter shaft threaded holes, and the cutting-off cutters and the cutter shaft are fixed through the cutter shaft threaded holes and the cutting-off cutter threaded holes by bolts. The cutting edge of each cutting-off cutter is arranged in the length direction of the cutter shaft, the section of the cutter shaft is of a cube structure, four side faces of the cutter shaft are installing faces, the four cutting-off cutters are installed on the four side faces of the cutter shaft respectively, and the cutter shaft is of a hollow structure inside. The corn harvester has the advantages of being good in cornstalk cutting-off effect, good in work balance and long in service life.
Description
Technical field
The present invention relates to agricultural machinery, particularly relate to maize harvesting machine.
Technical background
Maize harvesting machine comprises the reducing mechanism of collecting device, ear-picking unit and the stalk of cornstalk above, and reducing mechanism comprises cutter shaft, is connected with amputation knife on cutter shaft; In prior art, amputation knife is hinged on cutter shaft, namely alleged flail knife; Like this, the stalk of corn is pounded often the structure of slabbing instead of is chopped into the structure of section shape off, that is to say, the degree of grinding of corn straw is inadequate, affects the crushing effect of corn; In addition in the prior art, the cross section of cutter shaft is the structure of six prismatics, what install is three amputation knives, there is the poor shortcoming of balance, bring larger vibration to maize harvesting machine, also affect the service life of amputation knife, three amputation knives are installed on a cutter shaft and are also had and block the shortcoming that corn straw is grown.
Summary of the invention
Object of the present invention is exactly for above-mentioned shortcoming, provides a kind of and blocks that cornstalk is effective, the maize harvesting machine of the long service life of good, the machine of when work balance.
Technical scheme of the present invention is achieved in that a kind of maize harvesting machine, comprises the reducing mechanism of collecting device, ear-picking unit and the stalk of cornstalk above, and reducing mechanism comprises cutter shaft, is connected with amputation knife on cutter shaft; It is characterized in that: on described cutter shaft, there is the cutter shaft screw that amputation knife is installed, described amputation knife is the structure of strip, amputation knife has the amputation knife screw that coordinates cutter shaft screw, amputation knife and cutter shaft are fixed by cutter shaft screw, amputation knife screw with bolt, and the blade of described amputation knife is along the length direction setting of cutter shaft.
Say further, the cross section of described cutter shaft is the structure of square, and four sides of cutter shaft are installed surfaces, and four amputation knives are installed respectively in four sides.
Say further, described cutter shaft inside is hollow structure.
The invention has the beneficial effects as follows: such maize harvesting machine has that the cornstalk of blocking is effective, when work balance good, vibrate little, the advantage that machine service life is long.The cross section of described cutter shaft is the structure of square, four sides of cutter shaft are installed surfaces, and four amputation knives are installed respectively in four sides, can ensure that cornstalk blocks more broken, the balance of complete machine is better, four amputation knives are installed can be ensured the service life of amputation knife; Described cutter shaft inside is hollow structure, can alleviate cutter shaft weight, reduce costs.
Brief description of the drawings
Fig. 1 is the structural representation of cutter shaft of the present invention and amputation knife.
Fig. 2 is the A-A cross-sectional view in Fig. 1.
Wherein: 1, cutter shaft 2, amputation knife 3, bolt 4, blade 5, hollow-core construction.
specific embodiments:
Below in conjunction with accompanying drawing, the present invention is further illustrated.
As shown in Figure 1, 2, a kind of maize harvesting machine, comprises the reducing mechanism of collecting device, ear-picking unit and the stalk of corn above, and reducing mechanism comprises cutter shaft 1, is connected with amputation knife 2 on cutter shaft; It is characterized in that: on described cutter shaft, there is the cutter shaft screw that amputation knife is installed, described amputation knife is the structure of strip, amputation knife has the amputation knife screw that coordinates cutter shaft screw, amputation knife and cutter shaft are fixed by cutter shaft screw, amputation knife screw with bolt 3, and the blade 4 of described amputation knife is along the length direction setting of cutter shaft.
Say further, the cross section of described cutter shaft is the structure of square, and four sides of cutter shaft are installed surfaces, and four amputation knives are installed respectively in four sides, as shown in Figure 2.
Say further, described cutter shaft inside is hollow structure 5.
The foregoing is only specific embodiments of the invention, but architectural feature of the present invention is not limited to this, any those skilled in the art is in the field of the invention, and the variation of doing or modification are all encompassed in the scope of the claims of the present invention.
