But, owing to be formed in elongated and the central ground grading rotor 27b in contact area elongated central buoyancy aid 55 the place aheads on fore-and-aft direction and then the structure of shortening body total length of length before and after configuration is positioned between the left and right sides trailing wheel 11,11, so should the ground grading rotor 27b of central authorities be positioned at the below of the left and right sides lower link 41,41 of lifting linking member device 3, exist in when the portion of planting seedlings 4 is risen, central ground grading rotor 27b collides left and right sides lower link 41,41 and the problem of the portion of planting seedlings 4 of can't rising.
Therefore, make the central ground grading rotor 27b that is positioned at central buoyancy aid 55 the place aheads and be fastened on the structure that a plurality of connecting hole 77a of being arranged on the supporting member 77, spring 78 on 77b, the 77c hang central ground grading rotor 27b front portion by means of top.Therefore, plant seedlings when planting seedlings operation when portion 4 utilizes ground grading rotor 27 ground gradings in decline, thereby the ground grading rotor 27b of central authorities utilizes its weight to extend spring 78 a little makes it be in the ground grading operation that suits on the height identical with left and right sides ground grading rotor 27a, in addition, when the portion of planting seedlings 4 is risen, abut to left and right sides lower link 41 above the ground grading rotor 27b of central authorities, 41, rising along with the portion of planting seedlings 4, spring 78 extends longlyer, the ground grading rotor 27b of central authorities changes into the posture towards the below, and the portion of planting seedlings 4 is risen without barrier.
In addition, because central ground grading rotor 27b makes by means of top and is fastened on a plurality of connecting hole 77a that are arranged on the supporting member 77,77b, spring 78 on the 77c is hung the structure of central ground grading rotor 27b front portion, therefore, because the foozle of spring 78 or the weight error of central ground grading rotor 27b etc., when portion 4 is planted seedlings in decline, when the height of central ground grading rotor 27b and left and right sides ground grading rotor 27a not simultaneously, change the connecting hole 77a on engaging spring 78 tops, 77b, 77c, and then regulate central ground grading rotor 27b up and down the height, can make central ground grading rotor 27b identical, so that the ground grading operation that suits with the height of left and right sides ground grading rotor 27a.
Have again, if between supporting member 77 and central ground grading rotor 27b, get involved damper, make the structure of the vertical tremor that prevents that central ground grading rotor 27b from causing because of spring 78, then further improve the ground grading performance.In addition, replace the structure in the hole on change engaging spring 78 tops, make adjusting rod is set, so that regulating spring 78 also can with the structure of the clamped position of supporting member 77.
On the other hand, because being positioned at, the left and right sides chain shell 73,73 of making central ground grading rotor 27b has as lifting control the plant seedlings central buoyancy aid 55 of function of sensor of portion 4 and the structure between the left and right sides trailing wheel 11,11 (left and right sides auxiliary wheel 11a, 11a), therefore, left and right sides chain shell 73,73 prevents to be fallen on the central buoyancy aid 55 by the earth that left and right sides trailing wheel 11,11 (left and right sides auxiliary wheel 11a, 11a) is rolled, the front portion of central authorities' buoyancy aid 55 moves up and down aptly with the earth face, therefore plant seedlings portion 4 by suitably lifting control, carry out the good operation of planting seedlings.
