Abstract
The invention relates to a bearing supporting mechanism for a double-edge bidirectional rotating mowing machine. The bearing supporting mechanism comprises a lower blade, a bottom hood and an output shaft. A center hole of the lower blade is installed on the output shaft. A disc spring and the bottom hood are arranged below the bottom end of the lower blade. The top of the disc spring is in contact with the outer circle of the bottom end of the lower blade to enable the lower blade to be isolated from the end part of the outer side of the bottom hood. The bottom of the disc spring is arranged at the upper end of a bearing. The disc spring is supported by the bearing and is tightly pressed on the bottom end of the lower blade. The left end and the right end of the bearing are respectively fastened on the output shaft and the inner side shell of the bottom hood. The bearing is tightened at the end of the output shaft through a bolt. The bearing supporting mechanism for the double-edge bidirectional rotating mowing machine has the advantages that since the bottom hood and the blade are separated from each other through the disc spring and the bottom hood and the output shaft are separated from each other through the bearing, the effect that the bottom hood does not rotate is realized, the collision between the bottom hood and the bottom and hard objects such as stones due to contact is eliminated, and the phenomenon that the bottom hood is cracked or seriously worn is avoided.
Description
Technical field
The present invention relates to twolip bidirectional rotation mower device, more particularly to one kind are applied to twolip bidirectional rotation mowing
The bearing support structure of machine.
Background technology
Meadow due to urban green belts, golf course, farm level garden lamp is frequently necessary to periodically prune, to keep grass
The overall needs attractive in appearance and meeting athletic ground in ground, a kind of suitable onerous toil during this operation, therefore existing multiple works
The scheme of industry machinery, and be applied.In these Work machines, due to the small-sized and easy operation of hay mover, therefore
It is widely used.The hay mover of twolip bidirectional rotation is worked in the way of shearing due to bottom knife thereon, can be steadily efficient
Shearing cursive script, and high-speed cruising good stability, cutting efficiency is high, has wide range of applications.
The lower support structure of existing twolip hay mover is generally identical, is all to be pressed in blade face, due to thrust
Produced frictional force drives, and bottom cap can be rotated together with blade, and hay mover bottom can occur in hay mover operation process
Portion's thing hard with earth's surface, stone etc. contacts and collides, and often has bottom cover rupture or weares and teares to a high degree, thus leading to not normal
Operation.The two-way hay mover of part twolip does bottom cap using high hardness material so that main screw lift is generally heavier, and operator is easy
In fatigue, affect the working time, reduce operating efficiency.
Content of the invention
The technical problem to be solved is to provide a kind of bearings being applied to twolip bidirectional rotation hay mover
Structure, is realized bottom cap and is separated with blade, bottom cap does not rotate, and eliminates bottom cap thing hard with bottom, stone etc. and contacts
And the collision occurring, eliminate the phenomenon of bottom cap rupture or heavy wear.
The technical solution adopted for the present invention to solve the technical problems is: provides one kind to be applied to twolip bidirectional rotation and mows
The bearing support structure of machine, including bottom knife, bottom cap and output shaft, the mesopore of described bottom knife is contained on output shaft, institute
Stating bottom knife bottom arranged beneath has disk spring and bottom cap, and described disk spring top is cylindrical with bottom knife bottom to offset
Touch, so that bottom knife is separated with bottom cap, disk spring adjusts upper and lower gap blade it is ensured that compressing between upper bottom knife simultaneously,
Described disk spring bottom is placed in bearing upper end, and disk spring is pressed on bottom knife bottom by bearings, described bearing
The left and right sides is detained on side body in the output shaft side and bottom cap respectively, so that bottom cap is separated with output shaft, described
Bearing is tightened against the axle head of output shaft by bolt.
Described bearing is ball bearing.
Described bottom cap with the draw-in groove being adapted with bearing is provided with the opposite flank of output shaft.
Described bolt is hex bolts.
Described bottom cap is made with nylon plastic(s).
Beneficial effect
The present invention compared with prior art, has a following beneficial effect:
1st, borrow the feature of disk spring stress deformation itself, gap between blade can be automatically adjusted, so that upper and lower knife
Compression between piece is it is ensured that upper bottom knife is with cut mode work.
2nd, knife pole sheet pressure can be controlled to be to set smaller range value it is ensured that whole machine operation noise is little.
3rd, so that bottom cap is separated with blade by disk spring, so that bottom cap is separated with output shaft by bearing, bottom
Portion's cover lid itself does not rotate, and will not collide when the hard thing of bottom cap and earth's surface, stone etc. contacts, eliminate bottom cap normal
The rupture seen or heavy wear phenomenon.
4th, bottom cap material can be selected for nylon plastic(s), light weight compared with conventional material, mitigates operator's burden, provides
Operator's operating efficiency；Operator can put hay mover and drag in ground, need not hang act hay mover and just can steadily be cut.
Brief description
Fig. 1 is the assembling view of the present invention.
Fig. 2 is the partial enlarged drawing of the present invention.
Specific embodiment
With reference to specific embodiment, the present invention is expanded on further.It should be understood that these embodiments are merely to illustrate the present invention
Rather than restriction the scope of the present invention.In addition, it is to be understood that after having read the content of present invention instruction, people in the art
Member can make various changes or modifications to the present invention, and these equivalent form of values equally fall within the application appended claims and limited
Scope.
As shown in Figure 1-2, a kind of bearing support structure being applied to twolip bidirectional rotation hay mover, including bottom knife 1, bottom
Portion's cover lid 3 and output shaft 4, the mesopore of described bottom knife 1 is contained on output shaft 4, and described bottom knife 1 bottom arranged beneath has dish
Spring 2 and bottom cap 3, described disk spring 2 top is cylindrical inconsistent with bottom knife 1 bottom, makes bottom knife 1 and bottom cap
3 separate, and disk spring 2 adjusts upper and lower gap blade it is ensured that compressing between upper bottom knife, described disk spring 2 bottom is put simultaneously
In bearing 5 upper end, disk spring 2 is subject to bearing 5 support compression on bottom knife 1 bottom, and the left and right sides of described bearing 5 is detained respectively
Give as security on side body in output shaft 4 side and bottom cap 3, so that bottom cap 3 is separated with output shaft 4, described bearing 5 passes through spiral shell
Bolt 6 is tightened against the axle head of output shaft 4.
Described bearing 5 is ball bearing.
Described bottom cap 3 is provided with, with the opposite flank of output shaft 4, the draw-in groove being adapted with bearing 5.
Described bolt 6 is hex bolts.
Described bottom cap 3 is made with nylon plastic(s).
Embodiment 1
The present invention utilizes the feature of butterfly spring stress deformation, and in control, between bottom knife, pressure is to set smaller range value,
Noise is little, and disk spring can automatically adjust gap blade it is ensured that compression is it is ensured that upper bottom knife is to shear between upper bottom knife simultaneously
Mode work.
So that bottom cap is separated with blade by disk spring, so that bottom cap is separated with output shaft by bearing, bottom
