Description: BACKGROUND OF THE INVENTION 1. Field of the Invention The present invention relates to a ridge coating apparatus for continuously forming ridges in, for example, a field. 2. Description of the Related Art In the floating of a ridge shaping plate of this kind of ridge coating apparatus (following the original ridge and pressurizing a slope), the slope is strongly tightened by performing a floating operation at the time of dry field work, and wet field work is performed. Occasionally, a floating lock was used to secure the amount of soil on the slope (thickness of the slope). [0003] However, in the case of only two stages of such locking and unlocking of the floating, since the adjustment of the thickness of the slope at the time of wetland work is constant,
There was a problem that the ridge was easily collapsed when the moisture was high, and the tightening force was insufficient when the moisture was low, so that appropriate ridge shaping could not be performed. SUMMARY OF THE INVENTION Accordingly, the present invention provides a vibrator and a vibrator arm for mounting a ridge shaping plate which are supported on a lifting frame via a parallel link so as to be able to move up and down, and a parallel link is provided between the parallel link and the lifting frame. A guide frame is provided in the main body case of the ridge coating device, in which a lock arm for fixing is provided and a plurality of lock portions of the lock arm are provided so that the parallel link can be fixed in multiple stages.
Only, the lift frame is slidably supported via a guide roller on the guide frame, with mounting the lifting cylinder via a cylinder attachment seat to the main body case, remove the lock pin for fixing the lift frame and the guide frame It is provided freely, and the connecting member is fixed to the elevating frame via a set bolt so that the mounting position can be changed, and the elevating cylinder is connected to the connecting member. The cold region (high ridge region) or the warm region (low ridge region) ), Etc., it is possible to select the elevating area of the ridge shaping plate by the elevating frame according to the regional / field conditions. For example, when the shaping plate lowering allowance is insufficient in the standard state, the lock pin is inserted into the guide frame and the frame is raised and lowered. By fixing the frame and then retracting the elevating cylinder to change the coupling member to a higher position than the center, By removing the pin, the lowering margin is secured, and when the raising margin of the shaping plate is insufficient in the standard condition, the raising margin is secured by changing the connecting member to a lower position than the center, so the low ridge and high ridge The work conditions can be properly handled by a ridge coater with one specification,
