The invention relates to a machine for harvesting corns (a standing crop). For providing a small-drum crusher (for corn harvesters) which is rapid in crushing speed and good in crushing effect, the technical scheme adopted by the invention is as follows: a plurality of movable blade groups are arranged on a central rotating shaft in the crusher, movable blades in the movable blade groups are cooperated with a stationary blade arranged at the feed inlet of the crusher so as to realize the rapid crushing of straws. The small-drum crusher for corn harvesters provided by the invention is simple and reasonable in structure, and can be widely applied to corn harvesters.
Description
Technical field
The present invention relates to the standing crop harvest corn with machinery, be meant that specifically maize harvesting machine uses the doffer cutter mill.
Background technology
Maize harvesting machine is when harvest operation, and the maize straw of plucking behind the fringe has three kinds of processing approach: a kind of is that stalk directly is laid on the field without pulverizing, and concentrates then and collects.Adopt on the maize harvesting machine structure of this mode operation reduced crushed stalk, stirred collection, device such as spinner, throwing pipe; Another kind of processing mode is to adopt field-returning machine to pulverize the back directly to carry out straw-returning; To be stalk pulverize the back by cutter mill to the third processing mode directly carries out straw-returning, or the stalk centralized collection after stirring gathering unit, spinner, throwing pipe and will pulverizing.Adopt the processing approach of the third maize straw, reducing mechanism plays important effect in treatment step.If stalk is pulverized bad, adopt the straw-returning mode can influence the farming in soil; Adopt the mode of centralized collection can cause the obstruction that stirs device, spinner or throwing pipe, influence the smooth operation of reaping machine.
Summary of the invention
The purpose of this invention is to provide and a kind ofly pulverize that speed is fast, the maize harvesting machine of good crushing effect is used the doffer cutter mill, carry out crushed stalk when being implemented in the harvest corn machine operation synchronously.
The technical scheme that the present invention adopts is: maize harvesting machine is used the doffer cracker; This cracker comprises the cylinder shape cracker shell that has the two ends end face of an accumbency; Having charging aperture and discharging opening above the cylinder shape shell and below corresponding; It is characterized in that: the barrel of described charging aperture one side is outwards turned up and is formed the stationary knife installed surface, and it is inner that the stationary knife cutting edge of installing on it points to cracker; The two ends of cracker central rotating shaft adopt the center of bearing fixing end face in cracker shell two ends also coaxial; At least one group of movable cutter set is installed on central rotating shaft; Described movable cutter set comprises two disc moving knife installing racks that diameter is identical, and central rotating shaft passes the center of circle of moving knife installing rack, is provided with at least two breach planar shaped at the periphery of moving knife installing rack and becomes erecting bed; Erecting bed on two moving knife installing racks is in same plane, is used to install moving knife.
The barrel of above-mentioned charging aperture one side is outwards turned up and is formed the stationary knife installed surface, and the barrel of its opposite side is outwards turned up, and forms with the stationary knife installed surface of respective side and falls " eight " font charging aperture.
Described charging aperture extends to the other end by an end of cracker shell.
Described discharging opening extends to the other end by an end of cracker shell.
The inner movable cutter set of above-mentioned cracker is three groups.
Above-mentioned three groups of movable cutter set, its group with organize between the moving knife angle different.
Erecting bed moving knife on the above-mentioned moving knife installing rack is five.
On two corresponding erecting beds of moving knife installing rack moving knife is installed directly in the above-mentioned movable cutter set.
For increasing the intensity of moving knife, be provided with the moving knife fixed head in the bottom of moving knife, the two ends of moving knife fixed head are installed on the corresponding erecting bed of moving knife installing rack, and moving knife is installed on the moving knife fixed head.
Beneficial effect of the present invention is: this maize harvesting machine with the doffer cutter mill within it portion many group moving knife are set; The edge radius is identical and concentric; Formation the cooperating of different angles between the moving knife between group and the group; Can guarantee to cut off when stalk enters into cracker with different attitudes, reach the technical purpose that stalk is thoroughly pulverized.This invention is simple and reasonable, can be widely used on the maize harvesting machine.

Embodiment
Below in conjunction with embodiment the present invention is further specified.
As shown in Figure 2; Maize harvesting machine is used the doffer cracker; This cracker comprises the cylinder shape cracker shell that has two ends end face 1 of an accumbency; Having charging aperture 3 and discharging opening 4 above the cylinder shape shell and below corresponding, the barrel 2 of charging aperture one side is outwards turned up and is formed stationary knife installed surface 5, and stationary knife 6 cutting edges of installing it on point to cracker inside; The barrel 2 of charging aperture 3 opposite sides is outwards turned up, and forms with the stationary knife installed surface of respective side 5 and falls " eight " font charging aperture 3.
As shown in Figure 1, the charging aperture 3 in the present embodiment, discharging opening 4 extend to the other end by an end of cracker shell.
As shown in Figure 1; The two ends of cracker central rotating shaft 7 adopt bearing 11 to be fixed in the center of cracker shell two ends end face 1 and coaxial; At least one group of movable cutter set is installed on central rotating shaft; The movable cutter set quantity of installing in the present embodiment is 3 groups, and the quantity of movable cutter set can rationally be confirmed according to the length of cracker, the length of moving knife.
As shown in Figure 2; Described movable cutter set comprises two disc moving knife installing racks 8 that diameter is identical; Central rotating shaft 7 passes the center of circle of moving knife installing rack 8; Being provided with at least two breach planar shaped at the periphery of moving knife installing rack 8 and becoming erecting bed 12, is that the periphery at moving knife installing rack 8 evenly is provided with 5 erecting beds 12 in the present embodiment, and the quantity of erecting bed 12 can rationally be confirmed according to the rotating speed of central rotating shaft 7; The low quantity that can increase erecting bed 12 of rotating speed, the rotating speed height can suitably reduce the quantity of erecting bed 12.Erecting bed 12 on two moving knife installing racks 8 in said one group of movable cutter set is in same plane, and the two ends of moving knife 9 are installed on the corresponding erecting bed 12 of two moving knife installing racks.
For increasing the intensity of moving knife, as shown in Figure 2, be provided with moving knife fixed head 10 in the bottom of moving knife 9, the two ends of moving knife fixed head 10 are installed on the corresponding erecting bed 12 of moving knife installing rack 8, and moving knife 9 is installed on the moving knife fixed head 10.
Fig. 2, Fig. 3, Fig. 4 are respectively the cutaway views of three groups of movable cutter set, can find out through the contrast of moving knife angle in the accompanying drawing, and the moving knife radius of edge in three groups of movable cutter set is identical and concentric, the certain angle that staggers respectively of the moving knife in movable cutter set and the movable cutter set.
As shown in Figure 1, the moving knife installing rack in three groups of movable cutter set is concentric.
Movable cutter set and the moving knife angle difference between the movable cutter set can guarantee that stalk can successfully be cut off, and reach the finely disintegrated technique effect when the diverse location of charging aperture gets into cracker with different attitudes.
