(b) Conventional technology Conventionally, vibrating agricultural machines include subsoilers for soil layer improvement, bullet culvert excavators, root vegetable diggers, and root cutters, each of which has been manufactured as a dedicated machine. .

(c) Problems that the invention aims to solve As a result, farmers had to prepare a variety of specialized working machines, albeit of the same vibrating type, which had the disadvantage of increasing costs and requiring a large storage space. .

(d) Means for solving the problem According to the present invention, a beam receiver having a wide width in the lateral direction of the fuselage and having a substantially L-shaped cross section is connected to the vibration output part of the vibration generator, and , A beam pressing body having a wide width in the transverse direction of the fuselage and a substantially inverted L-shaped cross section is arranged opposite to the beam receiver, and the beam receiving body and the beam pressing body are connected by tightening bolts. A vibrating beam in the shape of a substantially rectangular rod, which connects various attachments for agricultural work in a cantilevered manner, is configured to be grippable between the beam receiver and the beam presser, so that it can be tightened and loosened in a clamping manner by screwing. The present invention aims to provide an attachment mounting structure for a vibrating working machine.

(e) Functions and Effects According to this invention, a beam receiver having a wide width in the lateral direction of the machine body and having a substantially L-shaped cross section is connected to the vibration output part of the vibration generator of a vibratory work machine. , a beam presser having a substantially inverted L-shaped cross section is disposed opposite to the beam receiver, and the beam receiver and the beam presser connect various thickening attachments in a cantilevered manner. Since the vibrating beam is grippable, the vibrating beam is prevented from twisting and is firmly supported, making it possible to efficiently carry out various operations using the blade.
