Abstract

The utility model discloses the crushed stalk mechanism below a kind of corn harvester.Be arranged on below corn harvester, crushing maize stalk, it is on main shaft, install driven pulley, bearing block and vertical cut cutter, and on backboard, installs one to be ranked cutter.

Description

Crushed stalk mechanism below a kind of corn harvester
Technical field
The utility model relates to a kind of maize harvesting machine, particularly relates to the crushed stalk mechanism below a kind of corn harvester.
Background technology
Current maize harvesting machine adopts Clothoid type straight knife, flail knife, hammer pawl to the pulverizing of maize straw, is generically and collectively referred to as hammer cutter.To be holes bottom cutter with the base on main shaft insert with pivot pin is connected for the fixed form of these cutters, and when main shaft is motionless, all cutters are in random state separately around main shaft.When main shaft High Rotation Speed, because the weight of self produces very large centrifugal force, do not having in resistant situation, its movement locus is vertical in main shaft, when the inlet of stalk is too much, resistance exceedes the inertial time of these hammer cutters, can turn round backward, radius of turn diminishes, and affects the pulverizing quality to stalk.Make main axis uneven, generation is trembled, is shaken, badly damaged header frame, causes frame breaking strain.If these hammer cutters is lightweight, during rotation, inertia is little, will can not reach pulverizing requirement to stalk.
Summary of the invention
Problem to be solved in the utility model is, current maize harvesting machine adopts Clothoid type straight knife to the pulverizing of maize straw, flail knife, hammer pawl, be generically and collectively referred to as hammer cutter, to be holes bottom cutter with the base on main shaft insert with pivot pin is connected for the fixed form of these cutters, when main shaft is motionless, all cutters are in random state separately around main shaft, when main shaft High Rotation Speed, because the weight of self produces very large centrifugal force, do not having in resistant situation, its movement locus is vertical in main shaft, when the inlet of stalk is too much, resistance exceedes the inertial time of these hammer cutters, can turn round backward, radius of turn diminishes, the pulverizing quality of impact to stalk, make main axis uneven, generation is trembled, shake, badly damaged header frame, cause frame breaking strain, if these hammer cutters is lightweight, during rotation, inertia is little, pulverizing requirement will can not be reached to stalk, a kind of lightweight vertical cut cutter is provided, utilize the power that the inertia of main shaft and driven pulley and driven pulley import into, make vertical cut cutter rotary cutting crushing straw, make spindle operation steady, reduce power consumption, crushed stalk mechanism below a kind of corn harvester stalk being produced to better crushing effect.
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) below corn harvester, comprise driven pulley (2), vertical cut cutter (3) is arranged on main shaft (4), stationary knife (5) is arranged on backboard, upper vertical cut cutter (3) relative main (4) installed of main shaft (4) for object of reference be fixed.
Said is the multiple vertical cut cutter (3) of the upper symmetrical installation of main shaft (4) at upper vertical cut cutter (3) of installing of main shaft (4).
The effect that the utility model is useful is: distinguishing hammer cutter is theoretically smash stalk by the kinetic energy of generation when deadweight and rotation, and the utility model is the power chopping stalk imported into by driven pulley, largely reduces the overall weight of crushed stalk mechanism.Reduce power consumption, especially to the stalk Be very effective of softness.Smooth running, is suitable for being arranged on below corn harvester and uses.
Accompanying drawing explanation
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 below a kind of corn harvester of the utility model.
Fig. 2 is the end view of Fig. 1.
Fig. 3 is the structure chart of vertical cut cutter.
In figure 1, bearing block, 2, driven pulley, 3, vertical cut cutter, 4, main shaft, 5, stationary knife.
Embodiment
In the embodiment shown in Fig. 1, Fig. 2, Fig. 3, by the crushed stalk mechanism below a kind of corn harvester, be arranged on the bearing block 1 below corn harvester, comprise driven pulley 2, vertical cut cutter 3 is arranged on main shaft 4, stationary knife 5 is arranged on backboard, on main shaft 4 install vertical cut cutter 3 relative main 4 for object of reference be fixed.
Main shaft 4 is installed multiple vertical cut cutter 3.
The course of work: when maize harvesting machine work is advanced, driven pulley 2 is driven to rotate, and by main shaft 4, vertical cut cutter 3 is rotated, and coordinates with stationary knife 5, can, the maize straw entered and soft and soggy pliable and tough corncob skin cutting and grinding, straw-returning be made to reach agronomy planting requirement.

Claims (2)
