In the front lower place of described casing (15), Holder for scissors (1) is set, this Holder for scissors (1) has upper plate (1a) and lower plate (1b), scissors driven pulley installing hole (1c) is offered at the middle part of upper plate (1a), an axle (3) is worn in this scissors driven pulley installing hole (1c), the upper end of seat axle (3) is by nut check, the lower end of present axle (3) is by bearing suit scissors driven pulley (4), scissors driven pulley (4) is positioned between upper plate (1a) and lower plate (1b), scissors driven pulley (4) is connected with the second drive (12) by belt, and in the bottom of scissors driven pulley (4), little axle (6) is installed prejudicially,
The front end of described upper plate (1a) is by bending continuously, form low order platform (1d), low order platform (1d) is offered rocking arm first installing hole (1e), described lower plate (1b) just offers rocking arm second installing hole (1f) to the position of rocking arm first installing hole (1e), bolt is through rocking arm first installing hole (1e) and rocking arm second installing hole (1f), and by nut check, this bolt is set with rocking arm (5) by bearing, rocking arm (5) is positioned between upper plate (1a) and lower plate (1b), and rocking arm (5) is in the front lower place of scissors driven pulley (4), the rear end of described rocking arm (5) is equipped with bearing pin (7), this bearing pin (7) is connected by the front end of bearing with connecting rod (8), the rear end of connecting rod (8) is connected with little axle (6) by bearing,
The front end of described lower plate (1b) exceedes the front end face of upper plate (1a), scissors installing hole (1g) is offered in the right and left symmetry of lower plate (1b) front end, the rear end of described lower plate (1b) upwards bends, form upper overturning, this upper overturning and upper plate (1a) rear end bend formed lower flange downwards and overlap fixing mutually;
Described upper overturning and lower flange overlap that overlapping is vertical is equipped with support shaft (9), the front end of this support shaft (9) and upper overturning and lower flange fix, the rear end of support shaft (9) is through two pieces of risers (14) bottom casing (15), bearing pin (10) is symmetrical arranged in the left and right sides of support shaft (9) front end, this bearing pin (10) is perpendicular with support shaft (9), and bearing pin (10) is fixed on the lower flange of upper plate (1a) rear end.
The present invention aims at and cuts the micro-cultivated all-in-one of grass and design, and cut the micro-cultivated all-in-one of grass and have dismountable scissors module, the present invention is the important component part of scissors module.On the top of scissors driving wheel of the present invention, end-tooth is set, this end-tooth can engage with the power of main transmission box, make the transmission of power of main transmission box to scissors driving wheel, scissors driving wheel is rotated by belt drive first drive, with coaxial the second drive of the first drive by belt by transmission of power to the driving mechanism in Holder for scissors, thus realize the opening and closing movement of scissors, complete machine is used as grass mower.When needs use as mini-size tillage machine, only the end-tooth on scissors driving wheel top and main transmission box need be thrown off, then pull down scissors module, replace with front-wheel and cultivated cutter, handover operation is not only convenient but also quick.Casing upper end and front end uncovered, on the one hand can save material, reduce production cost, on the other hand, for the transmission of power provides passage, be conducive to the power accepting main transmission box smoothly, and reposefully to shear driving mechanism transmission.
Holder for scissors moulding is simple, and be easy to processing and fabricating, production cost is low.Form arrangement space between the upper plate of Holder for scissors and lower plate, the shear driving mechanism parts such as scissors driven pulley, connecting rod and rocking arm can be held, thus saved space, make shear driving mechanism characteristics of compact layout, can machine volume be effectively reduced.
Scissors driven pulley installing hole in the middle part of upper plate is used for wearing an axle, so that scissors driven pulley is loaded on an axle by bearing holder (housing, cover); Rocking arm second installing hole in rocking arm first installing hole of upper front edge of board and lower plate matches, and for wearing bolt, the rocking arm of driving scissors is loaded on bolt by bearing holder (housing, cover).Rocking arm is in the front lower place of scissors driven pulley, and both dislocation, non-interference, respective dismounting is convenient, the good reliability of installation, and scissors driven pulley and rocking arm go slick.The parts composition toggles such as little axle, connecting rod and rocking arm, when scissors driven pulley rotates time, can drive rocking arm to carry out left and right reciprocally swinging by connecting rod, thus drive scissors folding operation.
Upper front edge of board forms low order platform, and low order platform shortens the distance between lower plate, while improving structural compactness further, bolt span can be avoided excessive and affect its structural strength.The scissors installing hole of lower front edge of board is used for wearing bolt and is connected with scissors, and fixed by two, left and right point between lower plate and scissors, the fastness of connection is good, and dismounting is very convenient.
The vertical fixed support axle of flange overlapping of Holder for scissors upper and lower plates, is connected between support shaft with upper and lower plates not only firmly but also reliably, can not comes off; Except junction, front end, the remainder of support shaft is unsettled, and support shaft is connected with two pieces of riser plug-in mountings of bottom half, can simplify the syndeton of casing and Holder for scissors, make assembly manipulation easier.Be symmetrical arranged bearing pin in the left and right sides of support shaft front end, bearing pin, for hanging scissors spring, is conducive to the dismounting of scissors spring convenient.
In order to simplify structure, be convenient to processing and fabricating, and guarantee there is enough intensity, prevent distortion or damage, described upper plate (1a) and lower plate (1b) form by the steel plate punched that thickness is 1.8-2.5mm.
In order to reduce material cost, except upper overturning, the remainder of described lower plate (1b) is pre-large post-small isosceles trapezoid.
At the journal stirrup (2) of the bottom welding band via hole of described lower plate (1b) front end, this journal stirrup (2) is equal to the distance of two scissors installing holes (1g).The anchor point of clutch line, for installing clutch line nut, so that clutch line location, is integrated on Holder for scissors, is not only conducive to clutch line cabling, and can reduce the cost making clutch line nut bracket separately by journal stirrup.
In order to prevent the axle from rotating, to guarantee that scissors driven pulley goes slick, reliably, scissors driven pulley installing hole (1c) is " D " shape, the cross section at seat axle (3) middle part is also " D " shape.
Described casing (15) is shaping by steel plate punched, and the bottom surface of casing (15) is low early and high after step surface, and riser (14) is positioned on the low order step surface of casing (15) bottom surface.Above structure casing is easy to processing and fabricating, and structural strength is reliable, can not deform or damage; Meanwhile, the compact of casing, takes up room little, arranges easily, can effectively reduce the volume of complete machine between shear driving mechanism and main transmission box.
Beneficial effect: the present invention is reasonable in design, structure is simple, by Holder for scissors for the parts such as scissors driven pulley, rocking arm provide arrangement space, thus make the parts dismounting such as scissors driven pulley, connecting rod, rocking arm convenient, whole mechanism driving is steady, go slick, it is firm to be connected between Holder for scissors with transmission case, is easy to assembling.
