Abstract
The utility model provides a straw crushing mechanism of a corn harvester. The straw crushing mechanism of the corn harvester is mounted below a cutting table of the corn harvester and is used for crushing corn straws. The straw crushing mechanism of the corn harvester is characterized in that a driven wheel, a bearing base and a tooth cutting tool are mounted on a spindle; a fixed tool assembly is transversely mounted at the position which is close to a rotation trace of the tooth cutting tool; and a fixed tool on the fixed tool assembly is inserted into a tooth cutting tool groove in a rotating process, so that the crushing degree of the straw is improved.
Description
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 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 a kind of maize harvesting machine that can 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.
the technical solution of the utility model realizes in the following manner: a kind of crushed stalk mechanism of maize harvesting machine, be arranged on the bearing block (1) of corn harvester below, comprise that driven pulley (2) is arranged on main shaft (3), at the upper tooth cutter (4) of installing of main shaft (3), during upper tooth cutter (4) rotation of installing of main shaft (3), relative main shaft (3) is fixed for object of reference, at close tooth cutter (4) rotary motion trace place, stationary knife assembly (5) is installed, stationary knife (6) during rotation on stationary knife assembly (5) inserts in the chase of tooth cutter (4).
Said stationary knife assembly (5) is to be arranged by a plurality of stationary knifes (6) to be fixed on same soleplate (7).
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 cutting and grinding, 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 maize harvesting machine of the utility model.
Fig. 2 is the end view of Fig. 1.
Fig. 3 is the structure chart of tooth cutter.
Fig. 4 is the structure chart of 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 tooth cutter, 5, the stationary knife assembly, 6, stationary knife, 7, soleplate.
Embodiment
In Fig. 1, Fig. 2, Fig. 3, Fig. 4, embodiment shown in Figure 5, crushed stalk mechanism with a kind of maize harvesting machine, be arranged on the bearing block 1 of corn harvester below, comprise that driven pulley 2 is arranged on main shaft 3, tooth cutter 4 are installed on main shaft 3, the relative main shaft 3 of tooth cutter 4 of installing on main shaft 3 is fixed for object of reference, near tooth cutter 4 rotary motion trace places, a plurality of stationary knife assemblies 5 are installed, and the stationary knife 6 during rotation on stationary knife assembly 5 inserts in the chase of tooth cutter 4.
The course of work: when maize harvesting machine work is advanced, driven pulley 2 is driven to rotate, make 4 rotations of tooth cutter by main shaft 3, because each stationary knife 6 on stationary knife assembly 5 inserts in the chase of tooth 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, can increase as required the quantity that stationary knife assembly 5 is installed, form multistage cutting and grinding, improve the quality of straw-returning, be fit to each region agronomy planting requirement.
Claims (2)
1. the crushed stalk mechanism of a maize harvesting machine, 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: at the upper tooth cutter (4) of installing of main shaft (3), during upper tooth cutter (4) rotation of installing of main shaft (3), relative main shaft (3) is fixed for object of reference, at close tooth cutter (4) rotary motion trace place, stationary knife assembly (5) is installed, stationary knife (6) during rotation on stationary knife assembly (5) inserts in the chase of tooth cutter (4).
2. the crushed stalk mechanism of a kind of maize harvesting machine according to claim 1 is characterized in that: stationary knife assembly (5) is to be arranged by a plurality of stationary knifes (6) to be fixed on same soleplate (7).
