Detailed description of the invention
The present invention will be further described below in conjunction with the accompanying drawings.
Being illustrated in figure 1 embodiment of the present invention hay mover, this hay mover is self-propelled mower, and the power source of so-called self-propelled mower, i.e. hay mover can band motor mower roller so that user does not promotes or tries hard to recommend motor mower hay mover just can be made to move with less.Described hay mover includes power source 1, and in the present embodiment, described power source 1 is gasoline engine.Power source 1 is arranged on base 2, and described base 2 is provided around roller 3, and described roller 3 makes hay mover to move freely.Base 2 rear is provided with grass box 4, and described grass box 4 is for collecting the useless grass cut down.Described grass box 4 is arranged over push rod 5, and user controls hay mover by operation push rod 5 and runs.
If Fig. 2 is to shown in 7, below described power source 1, being i.e. provided with cutting member bindiny mechanism 6 below base 2, described bindiny mechanism 6 is connected with the output shaft of power source 1 so that power source 1 can drive bindiny mechanism 6.Described bindiny mechanism 6 includes shaft coupling 61, location-plate 62, cutting member 63, pad 64 and screw rod 65.Described shaft coupling 61 is sheathed in the output shaft (not shown) of power source 1, the first end 611 of shaft coupling 61 is provided with groove 613, and hay mover is certainly walked belt sleeve and is located in described groove 613, therefore, shaft coupling rotates just can drive belt, thus band motor mower roller 3 moves.Shaft coupling 61 is made up of (such as Fig. 3) main component 601 and inserts 602, and described main component 601 is working of plastics, reduces the weight of shaft coupling 61, and meanwhile, working of plastics easily does decorative pattern so that shaft coupling is more attractive.Reinforcement 615 it is additionally provided with on main component 601.Described main component 601 is wrapped in inserts 602, and inserts 602 is metallic sintered products so that shaft coupling 61 has certain degree of hardness.Described shaft coupling 61 has the second end 612, and described location-plate 62 is arranged at the second end 612.Location-plate 62 is circular, and for stamping parts, location-plate has annular wall 621, and annular wall 621 is looped around on the second end 612 outer wall (as shown in Figure 7), and location-plate 62 is played certain position-limiting action.Described location-plate 62 is provided with boss 623, the present embodiment is provided with two boss 623, boss 623 coordinates with the hole, location 631 on cutting member 63 so that cutting member 63 can position and be installed on location-plate 62, and therefore cutting member 63 and location-plate 62 can rotate simultaneously.It is provided with adapting mechanism between described location-plate 62 and shaft coupling 61; make cutting member 63 by resistance stuck time; relatively rotating of certain angle is produced between location-plate 62 and shaft coupling 61; described relatively rotating refers to relatively deflecting between shaft coupling 61 and location-plate 62; it is different from continuous print and rotates skidding; so that boss 623 is hardly damaged, protect shaft coupling 61 and power source simultaneously.Described rotational angle is less than 90 degree, it is preferred that less than 10 degree, it is also possible to less, because the stiction between each parts of bindiny mechanism 6 is different, the angle rotated between different shaft couplings 61 and location-plate 62 is the most different, but will not be rotation of continuously skidding.In the present embodiment, described adapting mechanism includes the recess 614 being arranged on shaft coupling 61 and the claw 624 being arranged on location-plate 62, and described recess 614 is surrounded on inserts 602 outer wall, forms annular notch.Described claw 624 is positioned at around centre bore 625, is provided with four claws 624 in the present embodiment, is spaced 90 degree of settings.Described claw 624 both sides are provided with gap 622, and claw 624 includes inclined plane part 242 and tongue 241, and inclined plane part 242 makes location-plate 62 bottom surface 243 and tongue 241 have certain difference in height；Tongue 241 snaps in recess 614 so that shaft coupling 61 is connected with location-plate 62.Described cutting member 63 is positioned at below location-plate 62, and grass can be cut off by cutting member 63, and in the present embodiment, cutting member 63 is blade.Being additionally provided with installing hole 632 on cutting member 63, the center of circle in the center of circle of installing hole 632 and hole 631, location the most on the same line, thus it can be prevented that blade is anti-loaded.
Parts connected mode in bindiny mechanism 6 is, described screw rod 65 is squeezed into and is positioned on the power source output shaft of shaft coupling 61, through pad 64, cutting member 63, location-plate 62, the screwed hole offered, and above-mentioned parts are serially connected in together.Now, the protuberance 616 of described inserts 602 is through the installing hole 632 of cutting member 63, and cutting member 63 is pressed on shaft coupling, and described location-plate 62 is crushed between shaft coupling 61 and cutting member 63.When hay mover starts, the output shaft rotation of power source 1, drive cutting member 63 and shaft coupling to rotate, owing to cutting member 63 is set on the boss 623 of location-plate 62, therefore location-plate 62 rotates the most together, and the most whole bindiny mechanism 6 is in rotary state.When cutting member 63 cut to the bigger barrier of hardness or stuck time, cutting member 63 is by shock loading, now due to after turning an angle in the annular notch 614 on shaft coupling 61 of the claw on location-plate 62 power source quit work, i.e. in cutting member 63 is quit work during this period of time to power source 1 by impact, relative to rotating of having certain angle between location-plate 62 with shaft coupling 61 so that the boss 623 on shaft coupling 61 will not damage.
The garden instrument cutting member bindiny mechanism of the present invention; location-plate 62 is set between shaft coupling 61 and cutting member 63; shaft coupling 61 is connected with location-plate 62 on-fixed; make cutting member 63 when by shock loading; there is the rotation of certain angle between location-plate 62 and shaft coupling 61, protect shaft coupling 61 and described boss 623 is not damaged by；Meanwhile, it is the working of plastics of inserts that shaft coupling 61 uses by a metallic sintered products, alleviates the quality of shaft coupling, reduces cost, and owing to being working of plastics coated metal part, outward appearance is not easy to get rusty and attractive in appearance.The embodiment of the present invention is one embodiment of the present invention, any without departing from the principle of the invention and the replacement of design or improvement, all within protection scope of the present invention.
