Fig. 1 is the explanation to mower 20 and bracket 22 structures.Said mower is any type mower, and an operation board 23 and handle 24 are set on mower 20, and these parts installation sites can change.
Mower 20 has front end 26 and rear end 28 two parts, and the rear end 28 of mower defines a vertical plane 30.Handle 24 comprises that dead lever 32 and position bar 34, dead lever are provided with fixing hole 35, are fixed on dead lever 32 on the mower through screw.This handle is fixed on mode on the mower applicable to the mower of any kind.Dead lever extends upwardly elongatedness 44; Its place ahead is towards the front end of mower, and upwards is connected with the position bar, and dead lever and position bar monoblock cast form; Position bar 34 development lengths 46; The position rod rear end is towards the rear end of mower and near operation control panel 23, and the boom end mounting knob 38 in the position is dead lever 32 and position bar 34 coupling part shapes in an angle 42.
As previously mentioned; Handle 24 comprises dead lever 32, position bar 34 and handle 38, and setting operation dish and handle 38 between the front end 26 of mower and rear end 28 are when using bracket 22; Operator's 40 (see figure 3)s are using operation board 23 and a suitable height will being arranged to 38 o'clock, with handled easily.Dead lever and position pole length to each other or longer or short, between dead lever and position bar shape in an angle, its angle is that the obtuse angle also can be acute angle, or other possible combination.
Referring to shown in Figure 2; First is coupling, and to make operation platform rotation or platform be that the axle center is with respect to shank 54 rotations (referring to Fig. 6) with the first rotating shaft A to device; In this way, when mower affects bracket to advance, produce swing if run into uneven road surface; Mower is rotated (left or right) in the horizontal direction, this rotation be different by the caused swing of bracket.First is coupling, and device 56 makes platform 48 rotations or to be the axle center with the first rotating shaft A (or first trunnion axis) rotate with respect to shank 54.Equally, this device that is coupling can make mower and bracket can self-movement to adapt to these caused swings in uneven road surface.
The 3rd is coupling, and to make castor 52 be that the relative bracket supporting arm in axle center 50 rotates with the 3rd rotating shaft C to device 60.Like this, when mower traction bracket was run into uneven highway section, mower and bracket (left or right) or vertical direction (upwards downwards) separately in the horizontal direction rotated; The 3rd is coupling, and to make castor 52 be that rotate with respect to supporting arm 50 in the axle center with the 3rd rotating shaft C (or vertical axis) to device, make castor can self-movement with the swing that adapts to uneven road surface and cause and make the bracket that hangs over the mower back continue motion.
Be coupling in the device 56 first, the pore 70, that power transmission shaft 62 1 ends 74 are inserted through central siphon 66 is until the outer end of central siphon, and guard member 67 is fixed on central siphon 66 on the crossbeam 76 of platform 48 (also seeing shown in Fig. 9 and 10).
In Figure 10, through the first pivot pin fixture 68 power transmission shaft 62 is fixed in the central siphon 66, the first pivot pin fixture 68 is a kind of linchpin, and it comprises pivot pin 124, lock ring 126 and fasteners 128, and pivot pin one end is fixed on the fasteners, and the other end is a free end 130.Lock ring is installed on the fasteners, and its two end is all rotatable.During use, the free end 130 of pivot pin is inserted through axis hole 64 and engages (fixing) power transmission shaft 62 up to fasteners 128, through rotating lock ring 126 with fastening power transmission shaft 62.Equally, the first pivot pin fixture 68 is fixed on power transmission shaft 62 on the central siphon 66.The first pivot pin fixture is applicable to that also the mow connection of machinery of any other type fixes.
Second is coupling device 58 referring to Fig. 7 and shown in Figure 8.Second device that is coupling comprises and connects shank, pair of hook lever arm 84, mounting bracket 86, connects the support 85 and the second pivot pin fixture 88.
On mounting bracket 86, be provided with position limit piece 92 and 94 in opposite directions, and back side piece 96.On the piece of limit, be respectively equipped with piece hole, limit 100 and 102, the piece hole site, two limits on the piece of limit is accurately relative.
Connect support 85 and be flat; It has two plane surfaces 104 and 106 in opposite directions; Be provided with two in its surface and connect bracket holes 108 and 110, thereby screw 112 is fixed on the mower through being connected support in connection bracket holes 108 and the corresponding hole of 110 insertion mowers.
Connecting support 85 also can be fixed on the mower through welding or welding or other modes of monoblock cast.
Chock 114 monoblock casts, and be between the limit piece 94 of the surface 106 that connects support 85 and mounting bracket 86.Chock 114 produces a space between connection support and mounting bracket, connect support and be fixed on the mounting bracket, and mounting bracket is screwed on mower through connecting support.
For shank 54 is installed on the mounting bracket, hook arm 84 is inserted between the limit piece 92 and 94 of mounting bracket 86 in the opening 98, aims at piece hole, limit 100 and 102 until the connecting hole 82 of hook arm, and the second pivot pin fixture 88 is fixed on shank on the mounting bracket 86 then.The second pivot pin fixture 88 comprises pivot pin 116, pin hole 118 and pin 122; Pin is flat pin; When installing; Through piece hole, limit 100, pivot pins 116 are inserted in the piece hole, limit 102 of connecting hole of hook arm 82 and limit piece 94, up to pin hole 118 at mounting bracket with till connecting space between the support and exposing.When accomplishing aforesaid operations, pin 122 is passed pin hole 118 and pivot pin 116 is fixed on mounting bracket 86 and the hook arm 84.Like this, the hook arm through mounting bracket be connected support and be connected on the mower.
The 3rd be coupling device 60 more detailed description see shown in Figure 2ly, the 3rd device that is coupling comprises central siphon 132 and the yoke 134 that is provided with yoke axle 138.
Contain bearing in the central siphon 132, yoke axle 138 passes bearing and inserts in the central siphon.It is cylindric that central siphon is, and central siphon is fixed on the end position of bracket supporting arm, inserts bearing in the central siphon to constitute the of the present invention the 3rd device that is coupling through the yoke axle.When yoke is installed in 52 last times of castor, the yoke axle can pass through bearing free turn in central siphon; After bracket hung up mower, castor can rotate 360 ° of angles.
As stated, the present invention improves mower and bracket device, and the mower that is provided has more flexibility; Particularly when mower rotated or moves through steep area or abrupt slope, mower had better stability; The operator can have better view to the obstacle of mower front; Increase the regulating power of mower effectively; When the last bracket of mower load, the operator stands in when transferring to driving wheel on the operation platform and with operator's weight, and the mower driving wheel has better tractive force; And avoid the connection shank of bracket and castor when rotating, possibly come off.
Like this, the inventor has made the further improvement of mower of the present invention and bracket device, and this is invented concrete technical scheme describe.Obviously, these improvement and variation are clearly to existing mower, have substantive distinguishing features and obvious improvement, have good practical value simultaneously.
