Description
Technical field
The present invention relates to agriculture protective device technical field, and in particular to a kind of flexible handrail backplate.
Background technology
When carrying out field management operation, because plant strain is away from smaller, plant grows toward outside, and the machine in moving ahead is frequent
Branch, especially handrail pole can be encountered, larger infringement is caused to the tender shoots and plant leaves of new life.
Former handrail backplate is all smaller on the current machine such as garden supervisor and mini-tiller, only covers handrail pole front end, only
Beauty function can be played, can not still meet field job requirements well；Further, since the machine of in the market is of all kinds, no
The length of pole is respectively saved with machine handrail and front and rear pole institute is angled is not quite similar, and is to adapt to various types, it is necessary to go to process
Different moulds goes to manufacture, and work is complicated heavy.
The content of the invention
In view of the deficiencies of the prior art, the present invention provides a kind of flexible handrail backplate, existing backplate is changed
Enter, can more effectively avoid the tender shoots on machine scratch plant branch and leaf, while can opposite side backplate length and front and rear shield
The regulation of angle between plate, realize the flexible of handrail backplate.
The present invention is achieved through the following technical solutions：
A kind of flexible handrail backplate, including apron plate are provided, the rear end two sides of described apron plate are movably connected with
There is at least one set of adjustable in length and on the symmetrical side guard plate of apron plate center line, the rear end activity respectively of described side guard plate
It is connected with the finger guard on apron plate center line symmetrical setting.
Set side guard plate to be fixed on the outside of handrail pole and coordinate finger guard, handrail pole can completely be coated,
Reduce the damage of the stalk and blade to plant, be advantageous to protect plant branch tender shoots；The length of side guard plate can be adjusted, can
To be applicable the machine handrail of different length, convenient use.
Further, the rear end two sides of described apron plate are equipped with the arcwall face away from apron plate lateral surface, described
Arcwall face original position and final position it is all tangent with the side of apron plate, described arcwall face is hinged with side guard plate.
By setting arcwall face to carry out transition so that the surface of backplate is round and smooth, reduces the damage of the tender shoots and blade to plant
Bad effect, arcwall face, which is hinged side guard plate, can realize that arcuately face travel direction is adjusted side guard plate.
It is hinged preferably, described side guard plate is provided between two groups and two groups of side guard plates.
Two groups of be hinged side guard plates are set, and the convenient length for adjusting side guard plate matches with machine handrail length.
Further, described side guard plate includes the outer casing and inner casing for being located at same direction and being slidably connected, described
The front end of outer casing and the rear end of apron plate be hinged at, the rear end of described inner casing and the front end of finger guard are hinged.
Further, it is described be slidably connected refer to mutually to exist together with the madial wall vertical height of inner casing in outer casing it is solid
Surely there is the installing plate in band connection hole, length is equipped between described connecting hole and is more than connection pitch of holes guide rod.
Inner casing is slipped by guide rod and outer casing, it is possible to achieve the regulation of side guard plate length, convenient use.
Further, the outer casing between described apron plate and outer casing, two adjacent groups side guard plate and inner casing and
Inner casing is connected with finger guard in hinged place by opening up mounting hole hinge, and described mounting hole includes circular hole and with circular hole
The heart is the arc-shaped slot in the center of circle.
Outer casing and inner casing and inner casing and finger guard between apron plate and outer casing, two adjacent groups outer casing lead to
Cross hinge to be hinged, angle can be with left and right adjusting between front and rear backplate, and the arc-shaped slot on outer casing and finger guard ensure that front and rear
Angle can be adjusted up and down between backplate, to adapt to the change of angle between pole before and after different handrail poles.
Preferably, described arc-shaped slot is located at the inner side of circular hole and the company of arc-shaped slot center and the circular hole center of circle
Line is parallel with the length direction of side guard plate.
When circular hole is not adjusted under being used for backplate on the whole, backplate is fixed, it is necessary to when being adjusted up and down to backplate, taken
Bolt in lower circular hole, regulation arc-shaped slot center so that the bolt for being fixed on arc-shaped slot can be in arc-shaped slot
Under in the heart slidably, it is convenient adjust up and down.
Further, the upper surface of described outer casing is fixed with one towards in outer casing and tangent with upper surface half
Footpath is R arc surface I.
The upper surface of outer casing fixes one towards in outer casing and the arc surface I tangent with upper surface can utilize circular arc
Face I contacts with branch and twig, avoids vertical upper surface and the destruction caused to twig is directly contacted with twig.
Further, the upper surface of described inner casing is fixed with one towards in inner casing and tangent with upper surface half
Footpath is r arc surface II.
The upper surface of inner casing fixes one towards in inner casing and the arc surface II tangent with upper surface can utilize circle
Cambered surface II contacts with branch and twig, avoids vertical upper surface and the destruction caused to twig is directly contacted with twig.
Further, described arc surface I and arc surface II is the thickness of center of circle identical arc surface and R-r=outer casing
The thickness of degree=inner casing.
Arc surface I and arc surface II is concentric can cause inner casing arcwall face II outside outer casing arcwall face I
Medial surface it is in smoothing junction, be more convenient for using.
The invention has the advantages that：
First, there is one in the arcwall face outwards opened, the start bit of arcwall face after the connection of the side guard plate of apron plate side and both sides
Put tangent all with backplate side with final position, ensure that the protective action of backplate；
2nd, before the hinge connection between apron plate and outer casing, outer casing and inner casing and inner casing and finger guard ensure that
Angle can be with left and right adjusting between backplate afterwards, and angle can between the arc-shaped slot on outer casing and finger guard ensure that front and rear backplate
More than it is lower adjust, to adapt to the change of angle between pole before and after different handrail poles；
3rd, connected between outer casing and inner casing by guide rod, relative slip can be made along guide rod direction between the two, realized
Side backplate is to the adaptation in each section handrail strut lengths.
