Description

DETAILED DESCRIPTION OF THE INVENTION (Industrial field of application) The present invention relates to a side cover device in a rotary device.

(Prior Art) Conventionally, in a rotary device in which a rotary cover that covers a rotary tillage part is composed of an upper cover, a rear cover, and a pair of left and right side covers, a press-formed product of a sheet metal material is used for the side covers, and this rotary cover is used. It was attached to the left and right side frame parts of the machine frame, for example, side frames and chain cases with bolts.

(Problems to be solved by the invention) Since the conventional side cover is made of sheet metal as described above and is fixed to the side frame portion, a large amount of mud is covered by the side cover when cultivating on a flexible ground. There was a defect that it adhered to the inner surface of.

The present invention has been made in view of such conventional problems, and an object thereof is to prevent mud from adhering to the inner surface of the side cover.

(Means for Solving the Problem) The present invention is directed to a rotary cover that covers the rotary tilling part 6.
10 comprises an upper cover 11, a rear cover 12, and a pair of left and right side covers 13, and the side cover 13 is formed of an elastic plate 20 so that a gap 27 is provided inside the side frame portion 5 of the rotary machine frame 1. Which is a side cover device in a rotary device arranged in a vertical direction, in which reinforcing plates 21 and 22 are embedded in both upper and lower edge portions of the elastic plate 20, and these parts are attached to the side frame portion 5, and
The side portion of the upper cover 11 is connected to the side frame portion 5 with the upper edge portion of 20 interposed.
It is attached to.

(Operation) The side cover 13 is attached to the side frame portion 5 with the reinforcing plates 21 and 22 embedded in the upper and lower edge portions of the elastic plate 20, and between the elastic plate 20 and the side frame portion 5. Since the elastic plate 20 is allowed to vibrate by providing the gap 27, it is possible to prevent the elastic plate 20 from vibrating due to the collision of the soil mass at the time of cultivating, and thus to prevent the mud from adhering to the inner surface of the side cover 13.

(Embodiment) Hereinafter, the present invention will be described in detail with reference to the illustrated embodiment. In FIG. 7, reference numeral 1 is a rotary machine frame, an upper frame portion such as an input gear case 2, a pair of left and right support arms 3, and the like. The left and right side frames and the side frame portion 5 such as the chain case 4 are formed in a gate shape. 6 is a rotary tiller, which is a side frame 5 such as a side frame or a chain case 4.
It is composed of a claw shaft 7 that is horizontally mounted between the lower end portions of the and a plurality of plowing claws 8 provided on the claw shaft 7, and is transmitted from the input gear case side through a chain transmission mechanism 9 in the chain case 4. It is driven by power. 10 is a rotary tiller 6
Rotary cover to cover the upper cover 11, upper cover
A rear cover 12, which is pivotally connected to the rear end of 11, a pair of left and right front side covers 13, and a pair of left and right rear side covers 14. 15 is a gauge wheel support frame, 16 is a rear cover 12
It is a lowering mechanism.

The upper cover 11 is attached to the support arm 3 through the brackets 17 at the middle of the left and right sides, and the left and right ends are sandwiched by the upper sides of the side covers 13 as shown in FIG. Brackets 18 formed on the front and rear of the side frame portion 5 of the chain case 4 and the like are attached by bolts 19.

The front side cover 13, as shown in FIGS. 3 and 4,
An elastic plate 20 made of rubber or other elastic material is embedded with reinforcing plates 21 and 22 such as sheet metal at both upper and lower edges thereof, and the left and right sides are substantially symmetrical and both side surfaces are finished to be smooth. The front side cover 13 is formed with three mounting holes 23 at positions corresponding to the upper reinforcing plate 21 and four mounting holes 24 at positions corresponding to the lower reinforcing plate 22. . As shown in FIG. 1, the front side cover 13 is attached to the bracket 18 of the side frame portion 5 together with the upper cover 11 by the bolts 19 inserted into the two front mounting holes 23 of the upper reinforcing plate 21. ,
Further, the bolts 25 are inserted into the four mounting holes 24 of the lower reinforcing plate 22, and are attached to the side frame portion 5 itself and the brackets 26 formed before and after the side frame portion 5 itself.

On the other hand, between the front side cover 13 and the side frame portion 5 such as the side frame and the chain case 4, as shown in FIGS. 1 and 2, except for the portions corresponding to the reinforcing plates 21 and 22. A gap 27 is formed so that the elastic plate 20 can vibrate. 1 and 2, the side of the chain case 4 is shown, and a recess 29 is formed in the inner plate 28 of the chain case 4 to ensure a predetermined gap 27. Therefore, the elastic plate 20 and the inner plate 28 are not formed. Although some of them are in contact with each other, this degree of contact is not a problem.

The rear side cover 14, as shown in FIGS. 5 and 6,
A reinforcing plate 31 having a U-shaped cross section is adhered to a peripheral portion of an elastic plate 30 made of rubber or the like.
2, 33 are formed, and the upper cover 11 and the side frame are formed by the bolts 34, 25 which are inserted into the respective mounting holes 23, 32, 24, 33 in a state of being superposed on the rear end outer surface of the front side cover 13. It is attached to the part 5.

According to the above configuration, it is possible to prevent mud from adhering to the inner surfaces of the front side cover 13 and the rear side cover 14 at the time of plowing. That is,
When the tilling claw 8 jumps the soil mass at the time of tilling, and the soil mass collides with each side cover 13, 14, the elastic plate 20,
Since 30 is deformed and vibrates, the adhesion of mud is significantly reduced as compared with the conventional one made of sheet metal. Further, since the elastic plates 20 and 30 are used, the noise generated by the collision of the soil mass is significantly reduced.

Since the front side cover 13 has the upper and lower reinforcing plates 21 and 22 embedded in the elastic plate 20, it can be formed in a symmetrical shape.
Therefore, the left and right front side covers 13 can be used also, and the number of parts is reduced. In addition, the reinforcing plate 21
Therefore, both ends of the upper cover 11 can be fastened to the side frame portions 5 with this interposed therebetween, and in this way, vibration and noise of the upper cover 11 are also reduced.

When securing the gap 27 outside the front side cover 13,
As shown in the figure, if the brackets 18 and 26 are provided inside the inner plate 28 of the chain case 4, it is not necessary to form the recess 29 or the like in the inner plate 28 of the chain case 4.

The front side cover 13 and the rear side cover 14 are separately configured,
When both are superposed, a step is formed between the two by the thickness of the front side cover 13. Therefore, as shown in FIGS. 9 and 10, a front side cover 13 and a rear side cover 14 are provided.
If the elastic plates 20 and 30 are integrally formed, there will be no step. However, in this case, the front side cover 13 cannot be used for both left and right.

(Effect of the Invention) According to the present invention, it is possible to prevent the mud from adhering to the inner surface of the side cover 13 and also to prevent the generation of noise during tilling. In addition, the vibration of the upper cover 11 causes the side frame to vibrate. Propagation to the portion 5 can be blocked, the durability and attachment strength of the elastic plate side cover 13 can be improved by the reinforcing plate 21, and the elastic plate 20 can prevent rusting and damage of the reinforcing plate 21.
