Abstract
The utility model relates to a straw crushing mechanism under a corn harvester header. The straw crushing mechanism is mounted under the corn harvester header for crushing corn straws, and is characterized in that a driven wheel, bearing pedestals and claw-type cutting and tearing knives are mounted on a main shaft; a fixed knife assembly is transversely mounted in a position close to the rotation trace of the claw-type cutting and tearing knives; and when the straw crushing mechanism rotates, fixed knives on the fixed knife assembly are mutually embedded with the claw-type cutting and tearing knives, so that the crushing degree of straws is improved.
Description
Technical field
The utility model relates to a kind of maize harvesting machine, relates 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 upright maize straw of the horizontal cutter chopping of rotation 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
Problem to be solved in the utility model is, current middle-size and small-size maize harvesting machine is with the upright maize straw of the horizontal cutter chopping 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 the tilt maize straw enter and the soft and soggy pliable and tough corncob skin a kind of corn harvester below that can pulverize, be fit to large, medium and small type maize harvesting machine and install and use.
the technical solution of the utility model realizes in the following manner: the crushed stalk mechanism below a kind of corn harvester, be arranged on the bearing block (1) of corn harvester below, comprise that driven pulley (2) is arranged on main shaft (3), 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 when tearing cutter (4) rotation, relative main shaft (3) is fixed for object of reference, tear cutter (4) rotary motion trace place cutting near the pawl type, stationary knife assembly (5) is installed, stationary knife (6) during rotation on stationary knife assembly (5) cuts with the pawl type and tears cutter (4) embedding mutually.
Said stationary knife assembly (5) is to be arranged by a plurality of stationary knifes (6) to be fixed on same soleplate (7).
Said pawl type cut tear cutter (4) the pawl number more than 2 pawls.
The effect that the utility model is useful is: can uprightly, in length and breadth, the tilt maize straw enter and soft and soggy pliable and tough corncob skin can tear and cut pulverizing, and toothing is low, broken degree is high, reaches the agronomy planting requirement.
Description of drawings
Below in conjunction with drawings and Examples, the utility model is further illustrated.
Fig. 1 is the structure vertical view of the crushed stalk mechanism of a kind of corn harvester of the utility model 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.
In 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 arranged on the bearing block 1 of corn harvester below, comprise that driven pulley 2 is arranged on main shaft 3, cut in main shaft 3 upper mounting jaw types and tear cutter 4, the pawl type of installing on main shaft 3 cuts and tears the relative main shaft 3 of cutter 4 is fixed for object of reference, tear cutter 4 rotary motion trace places cutting near the pawl type, a plurality of stationary knife assemblies 5 are installed, and stationary knife during rotation on 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, tear cutter 4 and mutually embed because each stationary knife 6 on stationary knife assembly 5 and pawl type cut, 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 arranged on the bearing block (1) of corn harvester below, comprise that driven pulley (2) is arranged on 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 when tearing cutter (4) rotation, relative main shaft (3) is fixed for object of reference, tear cutter (4) rotary motion trace place cutting near the pawl type, stationary knife assembly (5) is installed, stationary knife (6) during rotation on stationary knife assembly (5) cuts with the pawl type and tears cutter (4) embedding mutually.
