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, particularly relate to a kind of bearing support structure that is applied to twolip bidirectional rotation mower.
Background technology
Because the meadow of urban green belts, golf course, farm level garden lamp often need to regularly be pruned, to keep the attractive in appearance of meadow integral body and the needs that meet athletic ground, a kind of suitable onerous toil during this operation, the scheme of therefore existing several work machinery, and be applied.In these Work machines, because mower is small-sized and easily operation, be therefore widely used.The mower of twolip bidirectional rotation, because bottom knife on it is worked in the mode of shearing, can steadily be sheared cursive script efficiently, and high-speed cruising good stability, and cutting efficiency is high, has wide range of applications.
The lower support structure of existing twolip mower is generally identical, all to be pressed in blade face, the frictional force producing due to thrust drives, bottom cap can be rotated together with blade, mower bottom can occur in mower operation process to be contacted and bumps with the hard thing such as earth's surface, stone, often there is end cover to break or higher degree wearing and tearing, cannot normal operation thereby cause.The two-way mower of part twolip adopts high hardness material to do bottom cap, makes complete machine weight generally heavier, and operator is easy to fatigue, affects the working time, reduces operating efficiency.
Summary of the invention
Technical problem to be solved by this invention is to provide a kind of bearing support structure that is applied to twolip bidirectional rotation mower, realize bottom cap separated with blade, bottom cap is not rotated, the collision of eliminating bottom cap to contact with the hard thing such as bottom, stone and occurring, elimination bottom cap is broken or the phenomenon of heavy wear.
The technical solution adopted for the present invention to solve the technical problems is: a kind of bearing support structure that is applied to twolip bidirectional rotation mower is provided, comprise bottom knife, bottom cap and output shaft, the mesopore of described bottom knife is contained on output shaft, described bottom knife bottom arranged beneath has disk spring and bottom cap, described disk spring top and bottom knife bottom cylindrical are inconsistent, bottom knife and bottom cap are separated, disk spring regulates upper and lower gap blade simultaneously, in assurance, between bottom knife, compress, described disk spring bottom is placed in bearing upper end, disk spring is pressed on bottom knife bottom by bearings, detain respectively in output shaft side and bottom cap on side body the left and right sides of described bearing, make bottom cap separated with output shaft, described bearing by bolt tightening in the axle head of output shaft.
Described bearing is ball bearing.
On the opposite flank of described bottom cap and output shaft, be provided with the draw-in groove suitable with bearing.
Described bolt is hex bolts.
Described bottom cap is made with nylon plastic(s).
Beneficial effect
The present invention compared with prior art, has following beneficial effect:
1, use the feature of the stress deformation of disk spring own, gap between adjustable blade automatically, thus making to compress between bottom knife, in assurance, bottom knife is with cut mode work.
2, can control cutter pole sheet pressure for setting value more among a small circle, guarantee that complete machine operation noise is little.
3, by disk spring, make bottom cap separated with blade, by bearing, make bottom cap separated with output shaft, self does not rotate bottom cap, when hard thing such as bottom cap and earth's surface, stone etc. contacts, can not bump, and eliminates common the breaking or heavy wear phenomenon of bottom cap.
4, bottom cap can be selected nylon plastic(s) with material, light with conventional material phase specific mass, alleviates operator's burden, and operator is provided operating efficiency; Operator can put mower and drag in ground, need not hang act mower and just can steadily cut.
Accompanying drawing explanation
Fig. 1 is assembling view of the present invention.
Fig. 2 is partial enlarged drawing of the present invention.
Embodiment
Below in conjunction with specific embodiment, further set forth the present invention.Should be understood that these embodiment are only not used in and limit the scope of the invention for the present invention is described.In addition should be understood that those skilled in the art can make various changes or modifications the present invention after having read the content of the present invention's instruction, these equivalent form of values fall within the application's appended claims limited range equally.
As shown in Figure 1-2, a kind of bearing support structure that is applied to twolip bidirectional rotation mower, comprise bottom knife 1, bottom cap 3 and output shaft 4, the mesopore of described bottom knife 1 is contained on output shaft 4, described bottom knife 1 bottom arranged beneath has disk spring 2 and bottom cap 3, described disk spring 2 tops and bottom knife 1 bottom cylindrical are inconsistent, bottom knife 1 and bottom cap 3 are separated, disk spring 2 regulates upper and lower gap blade simultaneously, in assurance, between bottom knife, compress, described disk spring 2 bottoms are placed in bearing 5 upper ends, disk spring 2 is subject to bearing 5 support compression on bottom knife 1 bottom, detain respectively on output shaft 4 sides and the interior side body of bottom cap 3 left and right sides of described bearing 5, make bottom cap 3 separated with output shaft 4, described bearing 5 is tightened against the axle head of output shaft 4 by bolt 6.
Described bearing 5 is ball bearing.
On the opposite flank of described bottom cap 3 and output shaft 4, be provided with the draw-in groove suitable with bearing 5.
Described bolt 6 is hex bolts.
Described bottom cap 3 use nylon plastic(s)s are made.
Embodiment 1
The present invention utilizes the feature of butterfly spring stress deformation, and in control, between bottom knife, pressure is for setting value more among a small circle, and noise is little, and disk spring adjustable blade gap automatically, compresses between bottom knife in assurance simultaneously, and in assurance, bottom knife is the mode work of shearing.
By disk spring, make bottom cap separated with blade, by bearing, make bottom cap separated with output shaft, self does not rotate bottom cap, contacts and can not bump with the hard thing such as earth's surface, stone, crack-free or heavy wear phenomenon, can guarantee that permanently effective work does not damage; Bottom cap material is nylon plastic(s), and quality is light, alleviates operator's burden, increases work efficiency; Operator can put body and drag in ground, need not hang act mower and just can steadily cut.
