Abstract
Disclosed is a straw crushing mechanism under a corn harvesting machine header. The straw crushing mechanism is installed under the corn harvesting machine header and used for crushing corn straws. A driven wheel, bearing seats and claw-shaped tearing cutters are installed on a main shaft. A fixed cutter assembly is transversely installed at a position close to rotation tracks of the claw-shaped tearing cutters, and fixed cutters on the fixed cutter assembly and the claw-shaped tearing cutters are mutually embedded during rotation. By means of the straw crushing mechanism under the corn harvesting machine header, the straw crushing degree is improved.
Description
Technical field
The present invention relates to a kind of maize harvesting machine, relate in particular to the crushed stalk mechanism of a kind of corn harvester below.
Background technology
The large-scale maize harvesting machine that uses at present is to adopt rear-mounted straw cutting apparatus crushing maize stalk.And middle-size and small-size maize harvesting machine is to adopt the horizontal cutter of rotation to shred upright maize straw below the front ceding of Taiwan, the maize straw that inclination is arranged, laterally enters has to leak cuts phenomenon, blade is easily blunt, can not shred soft and soggy pliable and tough corncob skin, cause stalk oversize, toothing is high, does not reach the agronomy planting requirement, is the jejune main cause of present middle-size and small-size maize harvesting machine.
Summary of the invention
The problem to be solved in the present invention is, current middle-size and small-size maize harvesting machine is to shred upright maize straw with the horizontal cutter of rotation, the maize straw that inclination is arranged, laterally enters has to leak cuts phenomenon, blade is easily blunt, can not shred soft and soggy pliable and tough corncob skin, cause stalk oversize, toothing is high, do not reach the agronomy planting requirement, provide a kind of can uprightly, in length and breadth, the crushed stalk mechanism of a kind of corn harvester below that can both pulverize of the tilt maize straw enter and soft and soggy pliable and tough corncob skin, be fit to large, medium and small type maize harvesting machine and install and use.
Technical scheme of the present invention realizes in the following manner: the crushed stalk mechanism of a kind of corn harvester below, be installed on the bearing block (1) of corn harvester below, comprise that driven pulley (2) is installed on the main shaft (3), cut in main shaft (3) upper mounting jaw type and to tear cutter (4), the upper pawl type of installing of main shaft (3) cuts that relative main shaft (3) is fixed for object of reference when tearing cutter (4) rotation, cutting and tearing cutter (4) rotary motion trace place near the pawl type, stationary knife assembly (5) is installed, and the stationary knife (6) during rotation on the stationary knife assembly (5) cuts with the pawl type and tears mutually embedding of cutter (4).
Said stationary knife assembly (5) is to be arranged by a plurality of stationary knifes (6) to be fixed on the same soleplate (7).
Said pawl type cut tear cutter (4) the pawl number more than 2 pawls.
The effect that the present invention is useful is: can uprightly, in length and breadth, the tilt maize straw enter and soft and soggy pliable and tough corncob skin can both tear and cut pulverizing, and toothing is low, broken degree is high, reaches the agronomy planting requirement.
Description of drawings
The present invention is further described below in conjunction with drawings and Examples.
Fig. 1 is the structure vertical view of the crushed stalk mechanism of a kind of corn harvester of the present invention below.
Fig. 2 is the end view of Fig. 1.
Fig. 3 is that the pawl type cuts the structure chart that tears cutter.
Fig. 4 is stationary knife.
Fig. 5 is the structure chart of stationary knife assembly.
Among the figure 1, bearing block, 2, driven pulley, 3, main shaft, 4, the pawl type cuts and tear cutter, 5, the stationary knife assembly, 6, stationary knife, 7, soleplate.
Embodiment
In Fig. 1, Fig. 2, Fig. 3, embodiment shown in Figure 5, crushed stalk mechanism with a kind of corn harvester below, be installed on the bearing block 1 of corn harvester below, comprise that driven pulley 2 is installed on the main shaft 3, cut in main shaft 3 upper mounting jaw types and to tear cutter 4, the pawl type of installing on the main shaft 3 cuts and tears cutter 4 relative main shafts 3 is fixed for object of reference, cutting and tearing cutter 4 rotary motion trace places near the pawl type, a plurality of stationary knife assemblies 5 are installed, and stationary knife during rotation on the stationary knife assembly 56 and pawl type cut and tear cutter 4 and mutually embed.
The pawl type cut tear cutter 4 the pawl number more than 2 pawls.
The course of work: when maize harvesting machine work is advanced, driven pulley 2 is driven to rotate, by main shaft 3 the pawl type is cut and tear cutter 4 rotations, because each stationary knife 6 on the stationary knife assembly 5 and pawl type cut and tear cutter 4 and mutually embed, can uprightly, in length and breadth, the tilt maize straw enter and soft and soggy pliable and tough corncob skin tear and cut pulverizing, can increase as required the quantity that stationary knife assembly 5 is installed, form multistage tearing and cut pulverizing, improve the quality of straw-returning, be fit to each region agronomy planting requirement.
Claims (3)
1. the crushed stalk mechanism of corn harvester below, be installed on the bearing block (1) of corn harvester below, comprise that driven pulley (2) is installed on the main shaft (3), it is characterized in that: cut in main shaft (3) upper mounting jaw type and tear cutter (4), the upper pawl type of installing of main shaft (3) cuts that relative main shaft (3) is fixed for object of reference when tearing cutter (4) rotation, cutting and tearing cutter (4) rotary motion trace place near the pawl type, stationary knife assembly (5) is installed, and the stationary knife (6) during rotation on the stationary knife assembly (5) cuts with the pawl type and tears mutually embedding of cutter (4).
2. the crushed stalk mechanism of a kind of corn harvester according to claim 1 below, it is characterized in that: stationary knife assembly (5) is to be arranged by a plurality of stationary knifes (6) to be fixed on the same soleplate (7).
