Abstract

The utility model discloses a straw crushing mechanism of a maize harvesting machine. A bearing seat is arranged under a maize harvesting machine cutting table, a driven wheel, the bearing seat and multi-fork cutters are arranged on a spindle, a plurality of stationary cutter assemblies are transversely arranged at positions close to rotation tracks of the multi-fork cutters, and stationary cutters and the multi-fork cutters are inserted mutually during rotation.

Description

A kind of crushed stalk mechanism of maize harvesting machine

Technical field

The utility model relates to a kind of maize harvesting machine, relates in particular to a kind of crushed stalk mechanism of maize harvesting machine.

Background technology

The maize harvesting machine that uses at present 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, does not reach the agronomy planting requirement, is the jejune main cause of present maize harvesting machine.

Summary of the invention

Problem to be solved in the utility model is, the current corn reaping 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 maize harvesting machine that can both pulverize of the tilt maize straw enter and soft and soggy pliable and tough corncob skin.

The technical solution of the utility model realizes in the following manner: a kind of crushed stalk mechanism of maize harvesting machine, be installed on the bearing block (1) of corn harvester below, comprise that driven pulley (2) is installed on the main shaft (3), at main shaft (3) multi-fork cutter (4) is installed, the upper multi-fork cutter (4) of installing of main shaft (3) relatively main shaft (3) is fixed for object of reference, at close multi-fork cutter (4) rotary motion trace place, a plurality of stationary knife assemblies (5) are installed, and stationary knife during rotation (6) embeds mutually with multi-fork 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 at main shaft (3) installation trident cutter (8), the upper trident cutter (8) of installing of main shaft (3) relatively main shaft (3) is fixed for object of reference.

The effect that the utility model is useful is: can uprightly, in length and breadth, maize straw and the soft and soggy pliable and tough corncob skin enter that tilt can both pulverize, and toothing is low, broken degree height reaches the agronomy planting requirement.

Among the figure 1, bearing block, 2, driven pulley, 3, main shaft, 4, the multi-fork cutter, 5, the stationary knife assembly, 6, stationary knife, 7, soleplate, 8, the trident cutter.

Embodiment

In Fig. 1, Fig. 2, Fig. 3, Fig. 5, embodiment shown in Figure 6, crushed stalk mechanism with a kind of maize harvesting machine, be installed on the bearing block 1 of corn harvester below, comprise that driven pulley 2 is installed on the main shaft 3, at main shaft 3 multi-fork cutter 4 is installed, the multi-fork cutter 4 relative main shafts 3 of installing on the main shaft 3 are fixed for object of reference, at close multi-fork cutter 4 rotary motion trace places, a plurality of stationary knife assemblies 5 are installed, and stationary knife 6 embeds mutually with multi-fork cutter 4 during rotation.

Stationary knife assembly 5 is to be arranged by a plurality of stationary knifes 6 to be fixed on the same soleplate 7.

The course of work: when maize harvesting machine work is advanced, driven pulley 2 is driven to rotate, make 4 rotations of multi-fork cutter by main shaft 3, because each stationary knife 6 on the stationary knife assembly 5 embeds mutually with multi-fork cutter 4, can uprightly, in length and breadth, maize straw and the soft and soggy pliable and tough corncob skin cutting and grinding of tilting and to enter, make straw-returning reach the agronomy planting requirement.

In Fig. 4, Fig. 5, Fig. 6, Fig. 7, another embodiment shown in Figure 8, straw crushing mechanism with a kind of maize harvesting machine, be installed on the bearing block 1 of corn harvester below, comprise that driven pulley 2 is installed on the main shaft 3, at main shaft 3 trident cutter 8 is installed, the trident cutter 8 relative main shafts 3 of installing on the main shaft 3 are fixed for object of reference, at close trident cutter 8 rotary motion trace places, a plurality of stationary knife assemblies 5 are installed, and stationary knife 6 embeds mutually with trident cutter 8 during rotation.

The course of work: when maize harvesting machine work is advanced, driven pulley 2 is driven to rotate, make 8 rotations of trident cutter by main shaft 3, because each stationary knife 6 on the stationary knife assembly 5 embeds mutually with trident cutter 8, can uprightly, in length and breadth, maize straw and the soft and soggy pliable and tough corncob skin cutting and grinding of tilting and to enter, make straw-returning reach the agronomy planting requirement.
