Abstract
The invention discloses a straw chopping mechanism under a header of a corn harvester. The straw chopping mechanism is mounted under the header of the corn harvester to chop corn straws, structurally comprises a driven wheel, a bearing block and a straight-cutting blade which are all mounted on a spindle, and further is provided with a row of fixed blades on a back retainer.
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
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.The fixed form of these cutters is that the hole of cutter bottom is inserted and is connected with pivot pin with the base on main shaft, when main shaft is motionless, all cutters around main shaft separately in random state.When main shaft High Rotation Speed, due to the very large centrifugal force of weight generation of self, do not having in resistant situation, its movement locus is vertical in main shaft, too much when the inlet of stalk, resistance surpasses the inertial time of these hammer cutters, backward revolution, radius of turn diminishes, the pulverizing quality of impact to stalk.Make main shaft rotation imbalance, produce and tremble, shake, 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
The problem to be solved in the present invention 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, the fixed form of these cutters is that the hole of cutter bottom is inserted and is connected with pivot pin with the base on main shaft, when main shaft is motionless, all cutters at main shaft around separately in random state, when main shaft High Rotation Speed, due to the very large centrifugal force of weight generation of self, do not having in resistant situation, its movement locus is vertical in main shaft, when the inlet of stalk too much, resistance surpasses the inertial time of these hammer cutters, revolution backward, radius of turn diminishes, the pulverizing quality of impact to stalk, make main shaft rotation imbalance, generation is trembled, shake, badly damaged header frame, cause frame breaking strain, if these hammer cutters is lightweight, during rotation, inertia is little, to can not reach pulverizing requirement to stalk, a kind of lightweight vertical cut cutter is provided, utilize the inertia of main shaft and driven pulley and the power that driven pulley imports into, make vertical cut cutter rotary cutting crushing straw, make spindle operation steady, reduce power consumption, stalk is produced to the crushed stalk mechanism of a kind of corn harvester below of better crushing effect.
Technical scheme of the present invention realizes in the following manner: the crushed stalk mechanism of a kind of corn harvester below, be arranged on the bearing block (1) of corn harvester below, comprise that driven pulley (2), vertical cut cutter (3) are arranged on main shaft (4), stationary knife (5) is arranged on backboard, the upper vertical cut cutter (3) of installing of main shaft (4) relatively main shaft (4) for object of reference be fixed.
Said is at the upper symmetrical a plurality of vertical cut cuttves (3) of installing of main shaft (4) at the upper vertical cut cutter (3) of installing of main shaft (4).
The effect that the present invention is useful is: the kinetic energy producing while distinguishing theoretically hammer cutter and be by deadweight and rotation smashes stalk, and the present invention is that the power importing into by driven pulley shreds stalk, has largely reduced the overall weight of crushed stalk mechanism.Reduce power consumption, remarkable to soft stalk effect especially.Smooth running, the suitable corn harvester below that is arranged on is used.
Accompanying drawing explanation
Below in conjunction with drawings and Examples, the present invention is further described.
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 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 of a kind of corn harvester below, be arranged on the bearing block 1 of corn harvester below, comprise that driven pulley 2, vertical cut cutter 3 are arranged on main shaft 4, stationary knife 5 is arranged on backboard, the relative main shaft 4 of vertical cut cutter 3 of installing on main shaft 4 for object of reference be fixed.
A plurality of vertical cut cuttves 3 are installed on main shaft 4.
The course of work: when maize harvesting machine work is advanced, driven pulley 2 is driven to rotate, and makes 3 rotations of vertical cut cutter, and coordinate with stationary knife 5 by main shaft 4, can, the maize straw entering and soft and soggy pliable and tough corncob skin cutting and grinding, make straw-returning reach agronomy planting requirement.
Claims (2)
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), vertical cut cutter (3) are arranged on main shaft (4), stationary knife (5) is arranged on backboard, it is characterized in that: the upper vertical cut cutter (3) of installing of main shaft (4) relatively main shaft (4) for object of reference be fixed.
2. the crushed stalk mechanism of a kind of corn harvester according to claim 1 below, is characterized in that: at the upper symmetrical a plurality of vertical cut cuttves (3) of installing of main shaft (4).
