On described wall position 14, as shown in Figure 3 and 4, have on the neighboring at diapire position 15, erect with certain interval 6 the vertical position 14a connecting portion 14b upper and lower with being connected respectively this adjacent vertical position 14a arranging in a circumferential direction, between vertical position 14a and upper and lower connecting portion 14b, there is upper and lower width w1, in lateral plan, form 6 slightly described openings 17. of elliptical shape with certain interval in a circumferential direction

At this moment, the value that the area (aperture area) of described opening 17 is set is larger than the area at wall position 14, this value, in the rotation of rotating knife 13, when wall position 14 rotating speed according to the rules rotates, the vegetations of cutting etc. can not enter anti-part 11 inside that are involved in from opening 17, and there have soil and mud or smear metal (being soil and mud etc. hereinafter referred to as these) to enter from the anti-upper opening 11a that is involved in part 11 to be anti-while being involved in part 11 inside, can be discharged to as described later and prevent being involved in part 11 outsides.In addition, the width w1 of the above-below direction of opening 17 is forming certain width along the direction of rotation イ of rotating knife 13, is remaining unchanged, and its upstream one side and downstream one side form half-circle-arc shape.

In addition, in the upper end at the described anti-wall position 14 that is involved in part 11, as shown in Figure 3, by this wall position 14 is carried out to bending to the inside, the position 14c that returns that outer peripheral face forms R shape is integrally formed.And, the anti-size that is involved in part 11 is for example 134mm left and right of its external diameter (diameter), as shown in Figure 2, the distance size L that the outer peripheral face 6a lower end of bearing cover 6 starts is 20～50mm, described height dimension h1 is set as for example 27mm left and right, but these sizes will, according to the form of the bearing portion 7 of the external diameter of the parent metal dish 18 of rotating knife 13 described later and cutting machine 1, be wished large as far as possible.

Further, described assembly wall position 16, as Fig. 3 and as shown in Figure 5, fixing hole 16b is set as the height dimension that can form, and this fixing hole 16b is positioned at the bottom that faces described opening 17.And, utilize this assembly wall position 16, as shown in Figure 5, prevent that being involved in part 11 is integrally fixedly mounted on cutting machine 1.

That is, utilize the fixing hole 16b at assembly wall position 16 on the screwed hole 19 of the outer peripheral face 6a lower end of bearing cover 6 formation, by fixed installation means, will prevent being involved in part 11 with bolt 20 and integrally fixedly mount.At this moment, bolt 20 on the circumferencial direction of assembly wall position 16c with certain interval setting example as 4～8, when preventing that being involved in part 11 is firmly fixedly mounted on bearing cover 6, under fixed installation state, below the lower end at assembly wall position 16 and diapire position 15, can more not be projected into rotating knife 13 1 sides (below of Fig. 2) than the installed surface of pivot flange 8.

In addition, described bolt 20 fastening, is the bottom that utilizes the anti-described opening 17 that is involved in part 11, and the instrument of screwdriver and spanner etc. 23 is inserted in opening 17, and bolt 20 is carried out fastening to fastening direction rotation.Anti-be involved in part 11 by this, can prevent from being as described later involved in cutting machine 1 end (bearing cover 6 parts) because rotating knife 13 makes the vegetation etc. of cutting.And, prevent that being involved in part 11 is fixedly installed on bearing cover 6, be not limited only to use bolt 20 to be fixed installation, for example by all-round or multiple positions of the upper and lower side at assembly wall position 16 etc. by welded formula be fixedly installed on the outer peripheral face 6a of bearing cover 6 also passablely, can take appropriate fixed installation means.

The described rotating knife 13 of installing on cutting machine 1 like this, as shown in Figure 2, there is parent metal dish 18 discoideus, that form multiple light weights hole (without diagram), on the center of this parent metal dish 18, form the installing hole 21 being installed on cutting machine 1.In addition, the outside of the installing hole 21 of parent metal dish 18 forms on tabular surface, on its position, neighboring, form multiple blades fixed installation position and blade carrier (without diagram) with certain interval, on each blade fixed installation position, the blade 22 that the superhard alloy of blade forms is welded and fixed installation by solder brazing respectively.

And, on the bearing cover 6 of connecting rod 4 ends that has fixedly mounted the anti-cutting machine 1 that is involved in part 11, by belling edge 9 and construction bolt 10 etc., rotating knife 13 is installed as described.Under the installment state of this rotating knife 13, the anti-assembly wall position 16 that is involved in part 11, bearing cover 6 lower ends are positioned at its opening 16a.In addition, by the height dimension h1 at the anti-wall position 14 that is involved in part 11 being set as to the value of regulation, between the upper end at wall position 14 and the outer peripheral face of connecting rod 4, guaranteed the gap size h2 (for example 2～15mm) of regulation.

And, under the installment state of rotating knife 13, driving cutting machine 1, rotating knife 13 rotating speed is according to the rules rotated, and cuts vegetation etc. by blade 22.In addition simultaneously, the vegetation of cut-out etc. contact with the outer peripheral face at the anti-wall position 14 that is involved in part 11, present anti-bounce status, prevent that the vegetation of cutting off etc. is involved in the part of the bearing cover 6 of cutting machine 1 end etc.

In addition, what the anti-opening 11a of portion being from it involved in part 11 entered has for example piled up a certain amount of soil and mud etc., can be discharged to the anti-outside that is involved in part 11 from opening 17.The discharge of this soil and mud etc., be the head (bearing cover 6 parts) of the cutting machine 1 during by cutting operation passes to head vibration when the wobbling action of direction (head is mutual mobile action on left and right directions) and rotating knife 13 rotate to the left and right, in cutting operation process, be automatically discharged to the anti-outside that is involved in part 11 from opening 17.

That is to say, in the outer peripheral face 6a lower end of the bearing cover 6 of cutting machine 1, be not projected under the state of rotating knife 13 1 sides, by preventing that being involved in part 11 use bolts 20 integrally fixedly mounts, use the anti-wall position 14 that is involved in part 11 four corner in the outside of the outer peripheral face 6a lower end of the bearing cover of cutting machine 16 can be carried out to interval covering with the distance L of regulation, the vegetations of cutting off by inhibition blade 22 etc. contact itself with bearing cover 6, utilization is arranged on the large opening 17 of area on wall position 14, anti-soil and the mud etc. being involved in part 11 will be entered into, by moving left and right of rotating knife 13 etc., automatically be discharged to the anti-outside that is involved in part 11.

Like this, according to described cutting machine 1, in the outer peripheral face 6a lower end of bearing cover 6, anti-be involved in part 11 be equipped with on the neighboring with the nearly circular diapire position 15 of plan view, this diapire position 15 with erect arrange between the integrally formed multiple walls position 14 of state and adjacent wall position 14, form than the more large-area multiple openings 17 in wall position 14 etc.Prevent that it is integrally hard-wired being involved in part 11, therefore by the anti-part 11 that is involved in when preventing that vegetation etc. is involved in the end of cutting machine 1, preventing that the soil and the mud etc. that splash from entering anti-is involved in part 11 inside, can alleviate operating personnel's burden, fully improves the efficiency of cutting operation.

In addition, because wall position 14 has the connecting portion 14b of multiple vertical position 14a and upper and lower side, between adjacent vertical position 14a and connecting portion 14b, form opening 17, so wall position 14 self can form opening 17, can improve the rigidity at wall position 14 self, conscientiously prevent the discharge that is involved in and ensures soil and mud etc. of vegetation etc.Also have, the aperture area of opening 17 is set greatlyr than the area at wall position 14, therefore can obtain practical anti-when being involved in effect by wall position 14, can be discharged to simply the anti-outside that is involved in part 11 by entering into anti-soil and the mud etc. being involved in part 11 by opening 17, can conscientiously prevent its accumulation.

In addition, prevent that being involved in part 11 is the openings 17 by wall position 14, use bolt 20 can be arranged on removably on bearing cover 6, can be as required by the anti-part 11 that is involved in when being arranged on cutting machine 1, the anti-replacing that is involved in part 11 etc. is also easy to, and can promote the easy-to-use of cutting machine 1.

Also have in addition, the anti-wall position 14 that is involved in part 11 self has formed larger area opening 17, can will prevent that being involved in part 11 self carries out lightweight, the weight that as far as possible suppresses the particularly end of cutting machine 1 increases, and can further improve the workability of cutting operation.In addition, anti-being involved on the upper end-face edge at wall position 14 of part 11, formed formed by round slip surface return to position 14c, therefore return to position 14c and can improve the rigidity at wall position 14 by this, when for example, the anti-distortion that is involved in part 11 when can preventing movable cutting machine 5 etc., also can improve operating personnel and touch anti-safety while being involved in part 11.

What Fig. 6-8 represented is that the described anti-distortion that is involved in part 11 is given an example.。Below, with the same position of described example on, use prosign describe.The anti-part 11 that is involved in of Fig. 6 is by the aperture area of opening 13, and what arrange in direction of rotation イ upstream one side is larger, less (or contrary) that downstream one side arranges.By setting the area of this opening 17, anti-soil and the mud etc. being involved in part 11 can be discharged to the anti-outside that is involved in part 10 effectively from the larger side of aperture area, prevent that part 11 is interior to be piled up preventing being involved in for soil and mud etc., simultaneously by most suitable aperture area 17 is set, can maintain the rigidity at the wall position 14 self of regulation.

In addition, the anti-opening 17 that is involved in part 11 of Fig. 7 is not by slightly elliptical shape of lateral plan, but formed by the smaller a little circular hole 17a of the height dimension h1 than wall position 14, this hole 17a is arranged on and closes on circumferencial direction.In the situation of this example, as shown in two pecked lines of figure, make the diameter of Yi Ce hole, downstream 17a of direction of rotation イ less than upstream one side, can obtain the action effect identical with Fig. 6 also passable.

In addition, the anti-part 11 that is involved in of Fig. 8 forms opening 17 by recess 17b.; on circumferencial direction on the neighboring at diapire position 15, interval according to the rules forms the tabular wall position 14 of the OBL for example circular arc of lateral plan, forms the opening 17 of recess 17 as top open (opening) between this adjacent wall position 14.This anti-being involved in part 11, is to be also involved in vegetation etc. at the wall position 14 that prevents rotation, by recess 17b, anti-soil and the mud etc. being involved in part 11 is discharged to outside simultaneously.

In the middle of this example, shown in two pecked lines, owing to being that the height dimension h1 at wall position 12 of direction of rotation イ upstream one side is than low formation of downstream one side, therefore make the area of recess 17b (opening 17) different also passable with downstream one side in upstream one side, wall position 12 is not to be formed by the tabular of the circular shape of Rack, for example, forms a wall position 14 by 1 or many bar-shaped parts (pole part) passable yet.

Use in the middle of the example of this recess 17b, also except obtaining with described example and each identical operation effectiveness of giving an example, because opening 17 is formed by recess 17b, can further make anti-being involved in the light-weighted while of part 11, make the anti-structure that is involved in part 11 simpler, manufacturing cost is cheap, and the anti-effect that is involved in is easy to be set to optimum state with discharge effect.Like this, the form of anti-the wall position 14 and the opening 17 etc. that are involved in part 11, according to the form of cutting machine 1, can obtain simultaneously and prevent being involved in function and discharge function, adopts rational structure.

And, in described example, the anti-part 11 that is involved in is the lower ends that are fixedly mounted on the bearing cover 6 that covers bearing portion 7, but according to the form of cutting machine 1, as long as by the anti-lower end that is involved in part 11 and is fixedly mounted on the flange and the cover etc. that are positioned at the outermost locational suitable shape that covers bearing portion 7.In addition, the shape of quantity, parent metal dish 18 and the anti-external diameter that is involved in part 11 etc. of the opening 17 in described example is an example, for example opening 17 is not 6, it is appropriate number of 2～8 grades etc., in the scope of main idea that does not depart from relevant each invention of the present invention, can adopt appropriate structure.

The present invention is not limited only to the cutting machine of engine-driven, can be used for all cutting machines that can cut vegetation etc. such as DYN dynamic cutting machine.

In sum, be only preferred embodiment of the present invention, be not used for limiting practical range of the present invention, i.e. all equivalences of doing according to the content of the present patent application the scope of the claims change and modify, and all should be technology category of the present invention.
