Description

A kind of mower bracket device

Technical field

The utility model relates to a kind of automatic hay mower and bracket, particularly a kind of automatic mower bracket device, and this bracket is installed on the mower, and it has good flexibility, stability and the strong ability that cuts the grass on a lawn when using.

Background technology

For many years, self-powered mower is higher because of its efficient that cuts the grass on a lawn, thereby is developed faster, also is well-known technology and on the mower tailstock, hang up bracket.The original bracket that uses of mower is general trailer, and this trailer does not adopt pivotal connection mechanism.For example, a kind of trailer of taking of the U.S., this trailer is hooked on the terminal vehicle frame of mower through two side rods, and this trailer is provided with seat on rack wheel, supply the user to be seated and control the mower direct of travel with pin.Afterwards, in the design of mower bracket, improved, for example, " a kind of station sitting posture mower bracket " reported, this bracket is provided with an elongated connection peg, through peg bracket is connected with mower.Report " a kind of movable bracket " is also arranged, which is provided with H shape support, on mower, be provided with T shape member, with cooperating of T shape member bracket is connected on the mower through H shape support.

Chinese patent (ZL032676441) discloses a kind of mower bracket, and bracket is connected with mower through connecting rod, is connecting horizontal U-joint and vertical u-shaped joint respectively at the two ends of connecting rod; The horizontal joint mower of ining succession; The vertical joint bracket of ining succession, connecting rod can be made 180 degree along the vertical ground direction and swings up and down like this, and bracket can wide-angle swing along the vertical connecting direction; When mower was turned or reversed end for end, bracket also can be along with turning or the tune follow-up.

Backward; People are provided with the rotating hinge structure in order to increase the flexibility of mower bracket on bracket, it is connected the bracket arm on the tailstock of mower through vertical rotating shaft; Increase flexibility, can pass through catwalk or little radius of turn neatly in use.For example; United States Patent (USP) (USPat.NO.5004251) open " a kind of bracket that is connected on the automatic mower "; It is provided with operation platform and two linking arms on bracket, linking arm of bracket is connected with mower through feathering axis, and another linking arm is connected with the operation platform; The operation platform can rotate around rotating shaft, has so just increased the flexibility of bracket when advancing or turn.

Equally, Chinese patent (ZL2010205533777) discloses a kind of mower bracket, and an end of its connecting rod is provided with clasp, and the other end is provided with connecting axle.On the mower tailstock, be provided with connecting hole,, connecting rod be movably connected on the bracket through cooperating of clasp and connecting hole.This structure, make mower hang up bracket rotate when advancing tune flexibly, steadily, safety.

Though above-mentioned improvement has made the performance of mower bracket obtain very big improvement, but still exist tangible structural defect with not enough.For example, when the commentaries on classics of operator's weight and mower is done the time spent apart from rotating shaft is applied, with regard to restive stress and the load forces that in the vertical pivots rotation, is produced.The deviation of this rotation and its structural defect are in operation bracket to have destabilizing factor; Both otherwise receive operator's weight limits; Keep enough tractive force and the bracket of mower advance and turn good flexibility and stability again, the above-mentioned type mower bracket is difficult to take into account.Therefore, design that a kind of new to have flexibility, stability and a reliability automatic mower bracket necessary.

Summary of the invention

Embodiment

The contrast accompanying drawing specifies its structure.

Fig. 1～10th, the structure of mower bracket device of the present invention and annexation diagram.

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.

Bracket 22 comprise the operation platform 48, a pair of bracket supporting arm 50, a pair of castor 52 is connected shank 54 with one, as previously mentioned, first be coupling device 56 be used for attended operation platform 48 be connected shank 54; Second device 58 that is coupling is used for connecting shank 54 and mower 20; The 3rd device 60 that is coupling is used for connecting castor 52 and bracket supporting arm 50.

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.

Second device 58 that is coupling makes and connects shank 54 and rotate (see figure 5) with 48 rotations of operation platform or around the second rotating shaft B with respect to mower; In this way; When mower traction bracket is advanced; Uneven road is smooth to cause swing if meet when mower goes, and will make beat (up or down) of mower in vertical direction, and this beating is that the twisting that is produced with bracket is different.Second device 58 that is coupling makes that to connect shank be that (second trunnion axis is vertical each other with first trunnion axis) rotated with respect to mower in the axle center with the second rotating shaft B, and makes mower and the self-movement of bracket ability to adapt to the swing of these uneven road surfaces.

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.

First device 56 that is coupling is further specified referring to Fig. 7.First device 56 that is coupling comprises power transmission shaft 62, the axis hole 64 on the power transmission shaft, beam barrel 66, guard member 67 and the first pivot pin fixture 68.

Power transmission shaft 62 is a rigid body, and it has rightabout two

ends
