Specific embodiment
It is specific embodiment of the utility model and in conjunction with attached drawing below, the technical solution of the utility model is made further
Description, but the utility model is not limited to these examples.
As shown in Figure 1, this grass trimmer includes fuselage and the walking mechanism being arranged on fuselage, mowing-apparatus and for adjusting
The height adjustment mechanism of mowing-apparatus relative altitude.
As shown in Fig. 2, height adjustment mechanism includes that bracket and the rotation gear 1 being arranged on body rack and setting are being cut
Sliding rack 2 on careless device, sliding rack 2 is vertically arranged and engages with rotation gear 1, and a driving is additionally provided on body rack
Motor, the motor shaft of the driving motor pass through transmission parts for power transmission to mowing-apparatus, and wherein transmission parts include sector
Gear set, directly to drive rod 3 and oblique drive rod 4, directly connect to drive rod 3 with sector gear group, sector gear group include two
A sector gear, one of sector gear are connect with the main shaft of cut-off blade in mowing-apparatus, another sector gear with
It is directly connected to drive rod 3, the both ends of oblique drive rod 4 pass through the motor shaft of universal joint and driving motor and directly to drive rod 3
Connection, oblique drive rod 4 include the first interlocking bar and the second interlocking bar, and the end face of the first interlocking bar, which extends, is equipped with a rectangular extension
Bar 5, the end face of the second interlocking bar offer one and the rectangular matched rectangular hole slot of 5 size of extension rod, and rectangular extension rod 5 is trapped in
In the rectangular hole slot.
As shown in Fig. 2, sliding rack 2 and rotation gear 1 there are two and be mutually aligned cooperation, two rotation gears two-by-two
A connecting rod is equipped between 1, connecting rod is equipped with and is fixed with a spanner 6, which includes in the " u "-shaped being buckled to, spanner 6
Two blocks of side plates and a swingle, swingle, which is freely rotated, to be arranged between two blocks of side plates, and one end difference of two blocks of side plates is fixed
In connecting rod.
The present apparatus adjusts height and position of the mowing-apparatus relative to body rack by way of rack-and-pinion, for people
Operate more conveniently, two rotation gears 1 are provided with connecting rod, and spanner 6, such people are provided in the connecting rod
Rotation gear 1 can be easily rotated by operation spanner 6, to drive sliding rack 2 to slide up and down, this mode adjusts height
The amplitude popularity of degree is very good, and mowing-apparatus can be made to adjust to any position in tooth location on sliding rack 2, and
And this programme also has a very crucial point, because the driving motor for providing mowing-apparatus power source is arranged on the outside,
And with the mutual alignment between it on transverse plane direction, so by the connection of the output main shaft and mowing-apparatus of driving motor
Dynamic transmission parts are also laterally to furnish, and are presented as in the design directly to drive rod 3, and directly to drive rod 3, laterally ornaments will be moved
Power source passes to sector gear group because mowing-apparatus be in the height direction it is transportable, directly by directly to biography
Lever 3 can generate mobile constraint to transmit power, in order to solve this problem be added in transferring element in this section in the design
Oblique drive rod 4, and the both ends of the oblique drive rod 4 and electric machine main shaft and directly to drive rod 3 respectively with the shape of universal joint
Formula connection, and the oblique drive rod 4 will have flexible function, could make mowing-apparatus during the decline will not be by
It is constrained, and oblique drive rod 4 has also just been designed to that the first interlocking bar and the second interlocking bar are spliced by the design.
As seen in figures 3-5, walking mechanism includes travel wheel 7, and the side of travel wheel 7 offers a ring annular groove 8, annular
Sliding is equipped with a compensation ring block 9 in slot 8, and the glide direction for compensating ring block 9 is consistent with the rotation main shaft of travel wheel 7, compensates ring block 9
Several gag lever posts 10 are equipped with towards the one side inside ring annular groove 8, offers and limits in the travel wheel 7 of 8 bottom of ring annular groove
10 quantity of bar is identical and the limit hole 11 of position alignment, and the one-to-one correspondence of gag lever post 10 is embedded in limit hole 11, in ring annular groove 8
It is additionally provided with a micro hydraulic bar 12, which connect with compensation ring block 9 and for driving the compensation sliding of ring block 9 to make it
The state for retracting or extending can be in relative to ring annular groove 8, the outer ring of compensation ring block 9 has arc, compensates ring block 9 from ring
Shape slot 8 extends its rear outer ring curvature and is mutually matched and is connected with the wheel arc of travel wheel 7, compensates and also sets between ring block 9 and travel wheel 7
There is the fastener that them can be made mutually to lock.
Usually, travel wheel 7 is in the state in Fig. 5, and the travel wheel 7 under the state is exactly a common wheel.And have
When grass trimmer can work under some rugged environments, such as the road surface of some muddy hollows, if still using Fig. 5 at this time
In travel wheel 7, easily lead to during rolling the travel wheel 7 skidding, so, in order to solve this problem, originally set
Meter, which uses, embeds a compensation ring block 9 that can voluntarily shrink according to demand, by micro hydraulic bar 12 by the compensation ring block 9
Extend, then lock, the lucky outer ring curvature of the compensation ring block 9 and the wheel outer ring curvature of travel wheel 7 itself match simultaneously
Linking, at this moment becomes the state in Fig. 4, it can be seen that the bottom of travel wheel 7 has gone out outside the arc contact surface of own, compensation
Ring block 9 also provides part can be with the face of ground face contact, and at this moment entire travel wheel 7 becomes larger with the area that road surface can contact,
Friction area can effectively be increased after travelling on some hollow heavy roads face, so that more steady in 7 rolling process of travel wheel.
