Summary of the invention

(problem that invention will solve)

The object of the present invention is to provide a kind of power digger to use attachment arrangement, it possesses grapple mechanism and cutting mechanism, and grapple can use separately simultaneously, can prevent that crops are wrapped on the slip cylinder part of cutter.

(being used to solve the method for problem)

It is the attachment arrangement that is installed on the arm leading section of power digger that the power digger that the present invention relates to uses attachment arrangement, and it is characterized in that comprising: grapple portion is arranged at top; And cutting part, have the rotating knife of the downside that is arranged at this grapple portion.

When using this attachment arrangement, can enough grapples with higher crops harnesses such as sugarcanes, and directly with cutter with root side harvesting and carrying.

In timber carrying etc., have the situation that does not need cutter.

Therefore, the present invention has the characteristic that grapple portion and cutting part releasably are connected.

In addition, for gathering in after with the crops harness, preferably make cutter in the enterprising line slip of fore-and-aft direction with grapple.

Therefore; In the present invention, preferably, cutting part can make rotating knife on fore-and-aft direction, slide; Said slide mechanism is equipped on inner cylinder portion the inboard of urceolus portion sliding freely; The cylinder and the piston rod of the inboard through being built in this urceolus portion and inner cylinder portion, inner cylinder portion be by extension and contraction control, the rotary driving part of the leading section through being installed on this inner cylinder portion and rotating knife is installed.

Like this, when the harvesting crops, can prevent that crops are wrapped on the cylinder mechanism of the sliding part that constitutes rotating knife.

(effect of invention)

Because attachment arrangement involved in the present invention possesses grapple mechanism and cutting mechanism, therefore, only is installed on the leading section of power digger, just can be used in harvesting and the carrying of crops.

And, owing to can cutting part be left, therefore, also can use as the grapple attachment arrangement, of many uses.

In addition, because will be in harvesting during crops, therefore the inner cylinder portion that is used to make cylinder that rotating knife slides on fore-and-aft direction and piston rod to be built in urceolus portion and to stretch from urceolus portion, can prevent that crops are wrapped on the slip cylinder part.

Embodiment

Describe according to the structure example of following accompanying drawing attachment arrangement involved in the present invention.

As shown in Figure 1; Attachment arrangement 10 have the leading section that is installed on power digger about two

installing plates

11,12, about jaw 22, the 23 grapple portion 20 that carries out on-off action with and the cutting part 30 of downside, cutting part advances the drive division 32 of rotating knife 31 through slide block 33 and retreats.

Its action describes in Fig. 2 and Fig. 5.

(a) under the state that the

jaw

22,23 of grapple portion about 20 is opened, crops 4 are taken in the inboard of the

jaw

22,23 of these both sides, and carry out harness.

Under this state, shown in Fig. 2 (b), (c), when rotating knife 31 advanced, crops were gathered in root side.

This attachment arrangement 10 is installed on the state of leading section of power digger 1 shown in Fig. 6.

Installing hole 11a shown in Figure 1,12a pin is connected in the leading section of the arm 2 of power digger 1, and installing

hole

11b, 12b pin be connected in the leading section of front rod 3, can be used in the harvesting of crops 4.

Below, according to Fig. 4 and Fig. 5 the structure example of grapple portion 20 is described.

With with respect to about installing

plate

11,12 mode vertical with horizontal direction,

pivotal support plate

21,21 is connected up and down abreast.

Through

pivot

21a, 21b with about the root side of

jaw

22,23 be articulated between this pivotal support plate up and down.

About

jaw

22,23 become the mode left and right sides subtend configuration of recess with inboard with the pawl of bowed shape.

For about the pawl of

jaw

22,23 about when closing each other do not interfere; In the present embodiment; About

jaw

22,23 be formed on the length of above-below direction of connecting plate gap be set; Make when the leading section of the pawl of inciting somebody to action bowed shape up and down connects on above-below direction through connecting

plate

22b, 23b the inboard of the jaw 23 on the jaw 22 entering right sides in left side.

About

jaw

22,23 through

tube connector

22a, 23a will be up and down the root side of pawl connect, and the connection carriage of general triangular shape is installed on this tube connector, thereby is connected with

pivot

21a, 21b.

When under the state of opening at the jaw of Fig. 5 (a) present embodiment being described; The connection carriage in left side has the connecting rod connection carriage 25a of epimere side and the cylinder of hypomere side is connected carriage 24b, and the connection carriage on right side has the connecting rod connection carriage 25c of all identical epimere side of last hypomere and the cylinder of hypomere side is connected carriage 24e.

The connecting rod in left side connects carriage 25a to have under the state of Fig. 5 (a) and is positioned at the pitman shaft 25b in the place ahead more than pivot 21a; The connecting rod on right side connects carriage 25c to have and is positioned at the pitman shaft 25d at rear more than pivot 21b, and with the both ends of synchronising (connecting) rod 25 be

coupling pitman shaft

25b, 25d about this.

On the other hand; The cylinder in the left side of hypomere side connects carriage 24b to have and is positioned at the gyroaxis 24c of rear side more than pivot 21a; The cylinder on right side connects carriage 24e and has the gyroaxis 24d coaxial with the pitman shaft 25d of synchronising (connecting) rod 25; About

gyroaxis

24c, 24d one of which is connected with the back pivot of cylinder 24, with the leading section pivotal connection of another and piston rod 24a.

Therefore, when giving prominence to through the piston rod 24a that omits cylinder 24 such as illustrated underground when advancing, shown in Fig. 5 (b) and since its action through synchronising (connecting) rod 25 make connecting rod connect

carriage

25a, 25c turns round, therefore, left and right sides jaw is closed each other.

In the present embodiment, through be arranged at pivotal support plate 21 about

block

21c, 21d and be arranged at block 22c, the 23c butt of pawl side, thereby the closing angle of

restriction jaw

22,23.

Below, according to Fig. 3 the structure example of cutting part 30 is described.

Use is arranged at the mounting flange 30a on the top of cutting part 30, is removable installed in the bottom 12c of installing

plate

11,12 through fixtures such as bolt 40.

Fig. 3 (c) illustrates the state of cutting part 30 after grapple portion 20 dismounting.

Cutting part 30 is installed on drive division 32 through driving shaft 32a with the rotating knife that is rotated 31, and drive division 32 is connected in the leading section of inner cylinder portion 33c, inner cylinder portion 33c with the state of outside seal under, carry out slides in telescopic in the inboard of the 33b of urceolus portion.

Cylinder 33d and piston rod 33e are built in the inboard of inner cylinder portion 33 and the 33b of urceolus portion, the leading section of piston rod 33e are connected in the inboard leading section of inner core through connecting portion 33f.

Thus, only through hydraulic piping being connected in connector 33a, while can rotating knife 31 be rotated through drive division 32 to advance, backward movement, and can prevent that crops are wrapped on the piston rod 33e.

In addition, the sidepiece from about urceolus portion 33 is provided with shank 34, makes it possible in the enterprising line height adjustment of above-below direction.

The 34a of foot about shank 34 has, 34a and the 34b of skid plate portion, the 34b that flatly are installed on the lower end of foot at fore-and-aft direction can prevent the decline that rotating knife 31 is too much.
