After that, the insertion pin 25 is inserted into the through holes 24 and 42 that match each other. In this way, as shown in FIG. 5, one of the earthenware forming bodies 10 can be changed to the earthing usage pattern. Then, the other soil cultivator forming body 10 can be changed to the soil culturing use form in the same procedure. In such a culture use form, the moving wheels 9 and 9 function as tail wheels.

  Here, the pair of left and right cultivator forming bodies 10, 10 in the cultivating soil use form pushes the cultivated soil in which the first shields 31, 31 are cultivated by the cultivating unit 5 forward, and the cultivated spilled outward. The second shields 32 and 32 and the third shields 33 and 33 guide the soil to the outside rear to cultivate the soil.

  When changing the cultivator forming body 10 to no culturing use form, the same procedure is used to remove the insertion pin 25 from the culturing use form described above → 180 ° sliding rotation of the mounting piece 23 → the insertion pin 25 By inserting, as shown in FIG. 4, it is possible to change one of the earthenware forming bodies 10 to a non-cultured earth use form. And it can change to the soil non-use form also with the same procedure also about the other soil cultivator formation body 10. In this state, operations other than cultivating such as moving the aircraft can be performed. At this time, the first shields 31 and 31 are disposed above the moving wheels 9 and 9, and the second shield 32 is disposed at a position shielding the outside of the moving wheels 9. By using the cultivator forming bodies 10, 10, it is possible to perform a fender function for preventing the attached soil and the like from being spun up to the worker side by the moving wheels 9, 9.

  In this way, the pair of left and right cultivator forming bodies 10 forming the cultivator are configured to use the cultivating position where the front and outside of the moving wheels 9 and 9 are shielded to perform the culturing function, and above the moving wheels 9 and 9. Since the position can be freely changed to the soil non-use position that shields the inner side and fulfills the fender function, each cultivator forming body 10 can function effectively at either the use position or the non-use position. Can do.

  In addition, in the soil use position, between the inner edge portions 40 and 40 of the first shields 31 and 31 of the soil cultivator forming bodies 10 and 10 facing each other close to the left and right, the vertical direction is straight. An interference avoidance gap 35 extending in the vertical direction is provided, and the rod-shaped resistance rod 7 extending in the vertical direction can be moved through the interference avoidance gap 35 so that the resistance rod and each cultivator forming body 10 interfere with each other. Is avoiding. That is, when the mutual use position of the resistance rod 7 and the moving wheels 9 and 9 is changed, the resistance rod 7 is lowered and disposed at the use position, and the earthenware former is integrally formed with the movement wheels 9 and 9. 10 and 10 are flipped up and arranged at the non-use position, and the earthenizer forming bodies 10 and 10 are lowered and arranged at the use position integrally with the moving wheels 9 and 9, and the resistance rod 7 is flipped up and placed in a non-use position. At the time of the movement of the two parts to be transferred, there is a moment when the two intersect each other. At this time, the resistance bar 7 moves in the interference avoidance gap 35 and interferes with the two cultivator forming bodies 10 and 10. I try not to. Here, it is necessary to form the gap between the interference avoidance gaps 35 as short as possible to ensure a good soil culturing function. However, the gap 35 is formed wider than at least the outer diameter of the resistance bar 7.

  In this way, since the interference between the resistance bar 7 and each cultivator forming body 10 is avoided via the interference avoidance gap 35, the resistance bar 7 used at the time of tillage work, and at the time of movement and soil cultivation The moving wheels 9 and 9 used (as tail wheels when cultivating) can be smoothly transferred to each other's use position, preventing the occurrence of problems such as damage and deformation due to interference between the two. it can. Therefore, it is possible to solve problems such as troublesome and storage locations for changing the resistance rod 7 and each cultivator forming body 10 one by one.
