Embodiment
Below in conjunction with accompanying drawing the utility model is described further.
Be illustrated in figure 1 as the utility model embodiment mower, this mower is self-propelled mower, so-called self-propelled mower, namely the power source of mower can drive the mower roller, makes the user not promote or tries hard to recommend motor mower mower is moved with less.Described mower comprises power source 1, and in the present embodiment, described power source 1 is gasoline engine.Power source 1 is arranged on the base 2, is provided with roller 3 around the described base 2, and described roller 3 makes mower to move freely.Base 2 rears are provided with careless case 4, and described careless case 4 is used for collecting the useless grass that cuts down.Described careless case 4 tops are provided with push rod 5, and the user is by the 5 control mower operations of operation push rod.
Shown in Fig. 2 to 7, described power source 1 below, namely base 2 belows are provided with cutting member bindiny mechanism 6, and described bindiny mechanism 6 links to each other with the output shaft of power source 1, makes power source 1 can drive bindiny mechanism 6.Described bindiny mechanism 6 comprises shaft coupling 61, location-plate 62, cutting member 63, pad 64 and screw rod 65.Described shaft coupling 61 is sheathed on the output shaft (not shown) of power source 1, the first end 611 of shaft coupling 61 is provided with groove 613, and mower is located in the described groove 613, therefore from walking belt sleeve, shaft coupling rotates just can drive belt, thereby drives 3 motions of mower roller.Shaft coupling 61 constitutes (as Fig. 3) by main component 601 and inserts 602, and described main component 601 is working of plastics, has reduced the weight of shaft coupling 61, and simultaneously, working of plastics is done decorative pattern easily, makes shaft coupling more attractive in appearance.Also be provided with reinforcement 615 on the main component 601.Described main component 601 is wrapped in inserts 602, and inserts 602 is metallic sintered products, makes shaft coupling 61 have 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, is stamping parts, and location-plate has annular wall 621, and annular wall 621 is looped around on the second end 612 outer walls (as shown in Figure 7), and location-plate 62 is played certain position-limiting action.Described location-plate 62 is provided with boss 623, be provided with two boss 623 in the present embodiment, boss 623 cooperates with locating hole 631 on the cutting member 63, makes cutting member 63 to locate and to be installed on the location-plate 62, so cutting member 63 and location-plate 62 can rotate simultaneously.Be provided with between described location-plate 62 and the shaft coupling 61 and connect mechanism; make cutting member 63 be subjected to resistance when stuck; produce relatively rotating of certain angle between location-plate 62 and the shaft coupling 61; describedly relatively rotate the relative deflection that refers between shaft coupling 61 and the location-plate 62; being different from continuous rotation skids; thereby make boss 623 not fragile, protected shaft coupling 61 and power source simultaneously.Described rotational angle is less than 90 degree, and is preferred, less than 10 degree, also can be littler, and because the stiction difference between bindiny mechanism's 6 each parts, the angle of rotation is also different between different shaft couplings 61 and the location-plate 62, but can not be the rotation of continuously skidding.In the present embodiment, the described mechanism that connects comprises the recess 614 that is arranged on the shaft coupling 61 and the claw 624 that is arranged on the location-plate 62, and described recess 614 is surrounded on inserts 602 outer walls, forms annular notch.Described claw 624 is positioned at around the centre bore 625, is provided with four claws 624 in the present embodiment, and 90 degree arrange at interval.Described claw 624 both sides are provided with gap 622, and claw 624 comprises inclined plane part 242 and tongue 241, and it is poor that inclined plane part 242 makes that location-plate 62 bottom surfaces 243 and tongue 241 have certain height; Tongue 241 snaps in recess 614, makes shaft coupling 61 be connected with location-plate 62.Described cutting member 63 is positioned at location-plate 62 belows, and cutting member 63 can cut off grass, and in the present embodiment, cutting member 63 is blade.Also be provided with installing hole 632 on the cutting member 63, the center of circle of the center of circle of installing hole 632 and locating hole 631 can prevent that thus the blade dress is anti-not on same straight line.
Parts connected mode in the bindiny mechanism 6 is, described screw rod 65 passes pad 64, cutting member 63, location-plate 62 and squeezes into the screwed hole of offering on the power source output shaft that is positioned at shaft coupling 61, and above-mentioned parts are serially connected in together.At this moment, the protuberance 616 of described inserts 602 passes the installing hole 632 of cutting member 63, and cutting member 63 is pressed on the shaft coupling, and described location-plate 62 is crushed between shaft coupling 61 and the cutting member 63.When mower started, the output shaft of power source 1 rotated, and drive cutting member 63 and shaft coupling and rotate, owing to cutting member 63 is set on the boss 623 of location-plate 62, so also rotation together of location-plate 62, this moment, whole bindiny mechanism 6 was in rotary state.When cutting member 63 cuts to the bigger barrier of hardness or when stuck, cutting member 63 is subjected to shock loading, this moment is owing to the back power source that turns an angle in the annular notch 614 of claw on shaft coupling 61 on the location-plate 62 quits work, namely cutting member 63 be subjected to impacting quit work during this period of time to power source 1 in, relative to rotating of certain angle arranged, make that the boss 623 on the shaft coupling 61 can not damage between location-plate 62 and the shaft coupling 61.
Garden instrument cutting member of the present utility model bindiny mechanism, between shaft coupling 61 and cutting member 63, location-plate 62 is set, shaft coupling 61 is connected with location-plate 62 on-fixeds, make cutting member 63 when being subjected to shock loading, the rotation of certain angle is arranged between location-plate 62 and the shaft coupling 61, protected shaft coupling 61 and described boss 623 not to be damaged; Simultaneously, shaft coupling 61 employings have alleviated the quality of shaft coupling by the working of plastics that a metallic sintered products is inserts, have reduced cost, owing to be working of plastics coated metal spare, outward appearance is not easy to get rusty and is attractive in appearance.The utility model embodiment is a kind of embodiment of the present utility model, and any replacement or improvement that does not break away from the utility model principle and design is all within protection domain of the present utility model.
