Description

The first step of grass-mowing machine work is turned to bit architecture system

Technical field

This utility model relates to the technical field of grass-mowing machine, and the especially first step of a kind of grass-mowing machine work is turned to Bit architecture system.

Background technology

At present, having a kind of grass-mowing machine on the market, press the button, work head can be round pole automatic turning Some angles, then with hands work head pulled and become the state of 90 degree with initial angle, the most just can be beating the grass Machine is put in and pushes the grass-mowing machine periphery along lawn on the ground stretching out the grass of lawn scope to destroying.This beat the grass The operation principle of machine is: the internal part for driving work head to overturn of this grass-mowing machine is that cylindrical screw compresses bullet Spring, when the head that works does not overturns, i.e. 0 degree when beating the grass, the internal spring being used for driving work head to overturn is in Most compressed state, has a snap close to stick the correlated parts of work head, thus work head can not be overturn； When user needs to be switched to 90 degree of deburring states, need press button to unclamp snap close, cylindrical screw Compression spring just releases energy, and drives the upset of work head, then puts in place with Hand supplementary upset.

In order to drive work head to overturn, the spring of the inside needs to put aside the biggest power, and this power is Allow put together machines difficult, and have influence on the inside dependency structure intensity, this rollover characteristics at any time may Losing efficacy, if to allow the upset of work first step put in place in this kind of structure again, the power of spring is also basic at this Upper much larger, it is clear that this structure is irrational.

Utility model content

The technical problems to be solved in the utility model is: in order to overcome the deficiencies in the prior art, it is provided that The first step of a kind of grass-mowing machine work is turned to bit architecture system.

This utility model solves its technical problem the technical scheme is that grass-mowing machine work first step upset Put in place structural system, have turning arm, rotary shaft, turning arm clasp, turning arm button, rotating spring, Rubber column, needle roller and turning arm button spring；Turning arm is mainly by left half turning arm and right half turning arm assembling Forming, rotary shaft is mainly assembled by left half rotary shaft and right half rotary shaft；Turning arm clasp and turning arm Button is fixed on left half turning arm by tapping screw, and rotating spring is fixed on left half by meson head screw On turning arm, rubber column is filled in the left half corresponding circular groove of turning arm；It is corresponding that needle roller is arranged on left half rotary shaft Groove in, the hook on rotating spring hooks needle roller, and rotary shaft is filled in the endoporus of turning arm clasp, and rotation Convex tendon in rotating shaft props up the rubber column on turning arm, and turning arm button spring is arranged on turning arm clasp.

The most specifically, the right side opening of the right side half rotary shaft described in technique scheme is provided with square groove one, The bottom that left half rotary shaft and right half rotary shaft are mutually spliced jointly offers and forms 90 degree of angles with square groove one Square groove two；Under a work original state parallel to the ground, turning arm clasp is in the rotation of compressive state Pivoted arm button spring is withstood, in the fixture block within turning arm clasp snaps in square groove one so that location work head；When Pressing turning arm button, turning arm button is rotated under arm clasp and presses, and the fixture block within turning arm clasp takes off From square groove one, rotating spring pulls rotary shaft to rotate, and the fixture block within turning arm clasp is because of turning arm button bullet To position work head in the effect jacking square groove two of spring.

The beneficial effects of the utility model: the simple in construction of this system, reasonable in design, click button, beat Grass machine just directly can be turned to 90 degree of deburring states from 0 degree of state of beating the grass, and need not put in place with Hand supplementary upset again, Easy and simple to handle, service efficiency is high, and repair rate is low.

Detailed description of the invention

Presently in connection with accompanying drawing, this utility model is described in further detail.These accompanying drawings are showing of simplification Being intended to, basic structure of the present utility model is described the most in a schematic way, therefore it only shows and this utility model Relevant composition.

See that Fig. 1, Fig. 2, Fig. 3 and Fig. 4, the first step of grass-mowing machine work are turned to bit architecture system, have rotation Pivoted arm 1, rotary shaft 2, turning arm clasp 3, turning arm button 4, rotating spring 5, rubber column 6, needle roller 7 and turning arm button spring 8；Turning arm 1 is mainly by left half turning arm 1-1 and right half turning arm 1-2 assembling Forming, rotary shaft 2 is mainly assembled by left half rotary shaft 2-1 and right half rotary shaft 2-2；Turning arm button Ring 3 and turning arm button 4 are fixed on left half turning arm 1-1 by tapping screw, and rotating spring 5 passes through Meson head screw is fixed on left half turning arm 1-1, and rubber column 6 is filled in left half turning arm 1-1 and justified accordingly In groove；Needle roller 7 is arranged in the left half corresponding groove of rotary shaft 2-1, and the hook on rotating spring 5 hooks rolling Pin 7, rotary shaft 2 is filled in the endoporus of turning arm clasp 3, and the convex tendon 2-1-1 in rotary shaft 2 props up rotation Rubber column 6 on pivoted arm 1, turning arm button spring 8 is arranged on turning arm clasp 3.Right half rotary shaft The right side opening of 2-2 is provided with the end that square groove one 2-3, left half rotary shaft 2-1 and right half rotary shaft 2-2 are mutually spliced Portion offers and square groove two 2-4 of square groove one 2-3 90 degree of angles of formation jointly.

Under a work original state parallel to the ground, i.e. 0 degree state of beating the grass, rotating spring 5 is in Big extended state, turning arm clasp 3 is in the turning arm button spring 8 of compressive state to be withstood, turning arm Fixture block within clasp 3 snaps in square groove one 2-3, thus firmly positions the head that works.

Turning 90 degrees when work head is turned over by needs, press turning arm button 4, turning arm button 4 is rotated arm Clasp is pressed for 3 times, and the fixture block within turning arm clasp 3 departs from square groove one 2-3, and rotating spring 5 pulls rotary shaft 2 rotate, and rotary shaft 2 is after flipping an angle, and the fixture block within turning arm clasp 3 is because of turning arm button bullet In effect jacking square groove two 2-4 of spring 8, thus firmly position the head that works, machine put on the ground, Machine is promoted to repair the edge on lawn, i.e. 90 degree deburrings along course.In rotary shaft 2 and work head upset During, the convex tendon 2-1-1 in rotary shaft 2 can be limited in specific angle by the circular groove on turning arm 1, Such position limiting structure can prevent rotary shaft 2 and work head upset excessive.Rubber column 6 in turning arm 1 circular groove Play the effect of buffering.

With above-mentioned according to desirable embodiment of the present utility model for enlightenment, by above-mentioned description, relevant Staff can carry out various change completely in the range of without departing from this utility model technological thought And amendment.The content that the technical scope of this utility model is not limited in description, it is necessary to root Its technical scope is determined according to right.
