Fig. 1 is a structure diagram of the present invention;
Fig. 2 is plan structure figure of the present invention.
Embodiment
Shown in Figure 2 like Fig. 1; The present invention relates to a kind of grass mower cutterhead height-regulating device, among the figure: leading screw 1, angle shape rod 2, nut 3, hind axle 4, M10 bolt 5, M10 locknut 6, front and back connector 7, heighten female 23, the power transmission shaft 24 of connector 8, forebay 9, forebay connecting plate 10, connecting rod 11, cutterhead connecting plate 12, bolt 13, nut 14, trailing wheel 15, afer bay connecting plate 16, right gripper shoe 17, afer bay 18, copper sheathing 19, bolt 20, locknut 21, clamping screw 22, locking.
The present invention except comprise forebay 9, afer bay 18, be contained in afer bay 18 belows trailing wheel 15, be contained in the power transmission shaft 24 of afer bay lower rear, with the cutterhead that afer bay is connected, also comprise:
By the screw-nut body that leading screw 1, nut 3 are formed, this screw-nut body is contained in afer bay 18 rear portions.
Left and right sides gripper shoe, label is enclosed within on the power transmission shaft 24 for the middle part of right this gripper shoe of gripper shoe rotationally among the figure, and the rear end of this gripper shoe is connected with afer bay 18 and front end is connected with hind axle 4.Label is right gripper shoe among the figure.
Before and after connector 7, its rear end and hind axle 4 are hinged and lower end front end and forebay 9 is affixed.
Connecting rod 11, its two ends are hinged with forebay and cutterhead respectively.For ease of installing, the two ends of connecting rod 11 are hinged with forebay connecting plate 10 and cutterhead connecting plate 12 respectively, and forebay connecting plate 10 is affixed with forebay 9 and cutterhead respectively with 12 of cutterhead connecting plates.)
The pin joint of the pin joint at connecting rod 11 two ends and the rear and front end of gripper shoe 17 constitutes parallelogram.
In addition, another end of angle shape rod 2 and an end of heightening connector 8 that is used to heighten are hinged, and this another end and hind axle 4 of heightening connector 8 is hinged.
The present invention utilizes one to be formed quadric chain front and back wheel is coupled together by right gripper shoe 17, connecting rod 11, forebay 9, afer bay 18, and wherein cutterhead has a connecting rod to link to each other with afer bay 18, and afer bay 18 both sides are affixed with bolt and cutterhead, form an integral body.Therefore just can regulate the height of afer bay and cutterhead simultaneously through regulating screw-nut body.
Following detailed operation principle.
Regulate leading screw 1 and screw with nut 3, leading screw is around copper sheathing 19 rotations, and angle shape rod 2 can be around the centre bore rotation of afer bay connecting plate 16, and it is fixing with locknut 6 through bolt 5 with angle shape rod to heighten coupling assembling 8, and can rotate.Front and back connector 7 and 13 fixing and locknut 14 lockings of forebay 9 usefulness bolts, affixed here.Connecting rod 11 is connected with cutterhead connecting plate 12 usefulness bolts with framework connecting plate 10 respectively, and this two place is all hinged.Right gripper shoe 17 can be rotated around the center of power transmission shaft 24, and affixed with hind axle 4.As shown in Figure 1, two pin joints of connecting rod 11 and right gripper shoe 17 constitute a parallelogram.The four edges of parallelogram is respectively right gripper shoe 17, connecting rod 11, forebay 9, afer bay 18.Wherein: on right gripper shoe 17, the connecting rod 11 two pin joint X are arranged respectively; The pin joint of forebay 9 and right gripper shoe 17 is on the same axis of trailing wheel 15; The pin joint of afer bay 18 and connecting rod 11 is on cutterhead connecting plate 12, and four some lines constitute parallelogram sturcutre.
When adjusting leading screw 1 turned clockwise, leading screw 1 drove nut 3 through screw thread and moves backward, and nut 3 drives angle shape rods 2 and is rotated counterclockwise around the center of framework connecting plate 16.Angle shape rod 2 drives again to be heightened coupling assembling 8 and moves up, and then makes and heighten coupling assembling 8 and also drive hind axle 4 and move up.Affixed with hind axle 4 because of right gripper shoe 17, so the center that the right gripper shoe 17 of hind axle 4 drives centers on power transmission shaft 24 rotates counterclockwise, the rear end of gripper shoe drives the frame whole height and reduces; Forebay 9 is rotated counterclockwise through framework connecting plate 10 drivening rods 11 simultaneously, descends thereby connecting rod 11 drives cutterhead through cutterhead connecting plate 12.After adjusting to the height that needs, with clamping screw 22 and locking female 23 right gripper shoe 17 is fixed with afer bay 18 again.Because cutterhead and afer bay are an integral body, so, can reach the whole purpose that reduces of cutterhead and frame through regulating leading screw.
When adjusting leading screw 1 is rotated counterclockwise, in like manner can reach the purpose that integral body is heightened.
