Abstract
A cutter device of a grassland breathing machine comprises a square tube shaft and a cutter assembly, wherein the cutter assembly is installed on the square tube shaft, two ends of the square tube shaft are provided with turned-over edges respectively, the turned-over edge at one end of the square tube shaft, which is connected with a power input shaft, is the left turned-over edge, the turned-over edge at the other end of the square tube shaft is the right turned-over edge, a washer is arranged on the square tube shaft and on the inner side of the left turned-over edge, the washer is connected with a profile of the square tube shaft, and the cutter assembly is located between the washer and the right turned-over edge. According to the cutter device, the washer is sleeved inside the left turned-over edge at one end of the square tube shaft, which is connected with the power input shaft, the inner side of the left turned-over edge is easy to deform, and the sleeved washer serves as a hoop and can prevent deformation of the square tube shaft. The cutter device is simple, but the problem in terms of quality is solved, and starting times of the grassland breathing machine is guaranteed to meet requirements. According to the cutter device, no process is added, an original device structure is not changed, and the increase of cost can be ignored.
Description
Technical field
The present invention relates to meadow ventilating machine cutter arrangement.
Background technology
Meadow ventilating machine, for improving the permeability on meadow, is conducive to the growth on meadow.The instrument of meadow ventilating machine has the wire claw adopting and clear up rubbish such as the fallen leaves on surface, meadow, there is the blade adopting and loosened the soil in surface, meadow, China Patent No. is 200720033955.2, name is called that the utility model of " cutter arrangement of meadow ventilating machine " discloses the cutting tool assembly that a kind of meadow ventilating machine uses, cutting tool assembly comprises rotating shaft and is connected to the cutter in rotating shaft, described rotating shaft is formed by connecting by for the polygonal cross-section hollow major axis of mounting cutter and the minor axis for installing clutch shaft bearing, the output shaft of gearbox inserts in major axis cavity, between the two for profile connect and for matched in clearance formed dismoutability connection, above-mentioned major axis adopts square tube to be square tube axle.The output shaft of gearbox is the power input shaft of cutter arrangement.Owing to being matched in clearance between the square output shaft of gearbox and the rectangular cavity of square tube axle, only ligament is very little, but due to inertia, opening, stop moment, the output shaft of gearbox is asynchronous with the rotation of square tube axle, produce shock between the two, the output shaft of the relative gearbox in square tube axoplasm ground is soft, often open, shut down, the position that square tube axle is contacted with output shaft of gear-box produces and is out of shape, the position of contact is outwards heaved gradually by plane, form arc surface, finally cause producing skidding between the output shaft of gearbox and square tube axle, the output shaft of gearbox cannot drive square tube axle to rotate, so above-mentioned cutter arrangement cannot ensure to reach the number of starts requirement to meadow ventilating machine.
Summary of the invention
The object of the invention is to propose a kind of meadow ventilating machine cutter arrangement that can prevent square tube shaft distortion.
For achieving the above object, the present invention takes following technical scheme: the meadow ventilating machine cutter arrangement that the present invention proposes comprises square tube axle and is arranged on the set of knives component on square tube axle, the two ends of square tube axle are respectively equipped with flange, the flange of one end that square tube axle is connected with power input shaft is left flange, then the flange of the other end is right flange, it is characterized in that: on square tube axle and the inner side being in left flange is provided with a packing ring, packing ring is connected with square tube spindle-type face, and described set of knives component is between packing ring and right flange.
Described packing ring has square hole, the square hole of packing ring and square tube axle interference fits.
Described set of knives component comprises the spacer between some blades and every two adjacent knife blades, and blade is connected with square tube spindle-type face.
Be provided with 1 to 2 resilient spacer between the spacer that in described set of knives component, the blade at two ends is adjacent with it, resilient spacer is connected with square tube spindle-type face.
The present invention overlaps a packing ring inside the left flange of one end that square tube axle is connected with power input shaft, is to hold yielding position inside the left flange of square tube axle, overlaps a packing ring and quite adds one hoop, can prevent the distortion of square tube axle.Although the present invention is simple, solve qualitative large problem, ensure that the number of starts of meadow ventilating machine reaches requirement.The present invention not adding technology, do not change original device structure, the increase of cost is negligible.

Embodiment
Embodiment 1
Meadow ventilating machine cutter arrangement shown in accompanying drawing 1 to Fig. 4, the set of knives component 2 comprising square tube axle 1 and be arranged on square tube axle 1, the two ends of tubular axis 1 are respectively equipped with flange, and the flange of one end that square tube axle 1 is connected with power input shaft is left flange 1a, then the flange of the other end is right flange 1b.Inside the left flange 1a of square tube axle 1, cover has a packing ring 4, and packing ring 4 is connected with square tube axle 1 profile.Square tube axle is square shaft, so packing ring 4 has square hole 4-1, and the square hole 4-1 of packing ring 4 and square tube axle 1 interference fits.Described set of knives component 2 is between packing ring 4 and right flange 1b.
Described set of knives component 2 comprises the spacer 2-2 between some blade 2-1 and every two adjacent knife blades, and blade 2-1 shifts to install, and blade 2-1 is connected with square tube axle 1 profile, takes blade 2-1 to be provided with square opening, the square opening of blade 2-1 and square tube axle 1 interference fits.The two ends, left and right of set of knives component 2 are blades, and be between the blade 2-11 of the high order end spacer 2-2 adjacent with it, be respectively provided with 1 to 2 resilient spacer 3 between spacer 2-2 that the blade 2-1n of low order end is adjacent with it, resilient spacer 3 is connected with square tube axle 1 profile.Resilient spacer 3 makes gapless between blade 2-1 and spacer 2-2.Above-mentioned set of knives component can be the blade assembly in the present embodiment accompanying drawing, also can be wire claw sub-assembly and other set of knives component.
When this cutter arrangement is installed, first one end of square tube axle 1 is completed flange on flanger, square tube axle 1 assembles packing ring, set of knives component, after having assembled, flanger completes the flange of the other end.During use, one end that square tube axle 1 has packing ring 4 is connected with the motor shaft of meadow ventilating machine or the output shaft of gearbox.
