Description
Technical field
The invention belongs to technical field of agricultural machinery, specifically, particularly cut the scissors driven pulley mounting structure on the micro-cultivated all-in-one of grass.
Background technology
Grass mower also known as mower, weeder, lawn mower etc., be a kind of for cutting the grass on a lawn, the machine tool of vegetation etc., it can save the activity duration of weeding workman, effectively reduces a large amount of human resources.
Mini-size tillage machine with small diesel engine or gasoline engine for power, the features such as have lightweight, volume is little, and structure is simple.Mini-size tillage machine is widely used in the nonirrigated farmland, paddy field, orchard etc. on Plain, mountain area, hills.Mix corresponding facility can carry out drawing water, generate electricity, spray the operation such as medicine, spray, also can draw towed vehicle and carry out short-distance transport, mini-size tillage machine freely can be exercised in field, user-friendly and deposit, eliminating the worry that large-scale farm machinery cannot enter mountain area field, is that vast farmers friend substitutes the cultivated optimal selection of ox.
At present, grass mower and mini-size tillage machine, as two kinds of independently farm machineries, play its exclusive function separately.If can by cut grass and ploughing and weeding two kinds of function i ntegration on a kind of machine, will greatly reduce the acquisition cost of user, and be conducive to reduction parking space.Therefore, those skilled in the art be just devoted to research and development cut grass micro-cultivated all-in-one.
Summary of the invention
Technical problem to be solved by this invention is to provide a kind of structure simply to cut grass-micro-cultivated dual-purpose machine scissors driven pulley arrangement.
Technical scheme of the present invention is as follows: one cuts grass-micro-cultivated dual-purpose machine scissors driven pulley arrangement, it is characterized in that: 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), and scissors driven pulley (4) is positioned between upper plate (1a) and lower plate (1b);
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), 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 (5), the front end of this support shaft (5) and upper overturning and lower flange fix, and be symmetrical arranged bearing pin (6) in the left and right sides of support shaft (5) front end, this bearing pin (6) is perpendicular with support shaft (5), and bearing pin (6) is fixed on the lower flange of upper plate (1a) rear end.
The present invention aims at and cuts grass-micro-cultivated dual-purpose machine design.Adopt above technical scheme, 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 and scissors driven pulley non-interference, respective dismounting is convenient, the good reliability of installation, and scissors driven pulley goes slick.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, is conducive to wearing fast with scissors transmission case being connected.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.
Beneficial effect: Holder for scissors moulding of the present invention is simple, processing and fabricating is easy, and structural strength is reliable, can not deform or damage; Holder for scissors and scissors transmission case easy to connect, for the parts such as scissors driven pulley provide arrangement space, thus make the dismounting of scissors driven pulley convenient, go slick, and complete machine structure can be made compacter, volume is smaller and more exquisite.
