[Industrial applications]

 The present invention relates to the structure of a planting claw of a planting part of a grass transplanter.

[0002]

[Prior art]

 Conventionally, it has been known that a grass transplanter has been improved by improving the seedling mounting table of the rice transplanter, and the planting part of the grass transplanter has almost the same structure as the rice transplanter, and it has a mat shape. The planting claws that cut out a certain amount of rush from the seedling table on which the grass seedlings were placed had a structure similar to that of rice transplanters.

[0003]

[Problems to be solved by the device]

 However, in the conventional planting claw, as shown in Fig. 8, the receiving portion at the tip of the push rod is formed in a V shape when viewed from the front. In the receiving part of the section, the rush seedlings hit the front surface of the receiving part and bent, and when the planting was carried out, the push rods were extended to push out the grass seedlings, so the seedlings would be pushed into the soil while being broken, and it would be easily scratched. The planting posture had collapsed and the seedlings had fallen, adversely affecting the growth of rush.

 The problems to be solved and the means for solving the present invention are as described above. Next, a specific configuration of the present invention will be described with reference to the accompanying drawings. Fig. 1 is an overall side view of the hay transplanter, Fig. 2 is a perspective view of the hay seedling cut out by the planting claw of the present invention, and Fig. 3 is a front view and side view of the push rod receiving portion of the planting claw. 4 is a perspective view showing a second embodiment of the planting nail, FIG. 5 is a front view and a side view of the receiving portion in FIG. 4, and FIG. 6 is a perspective view showing a third embodiment of the planting nail. FIG. 7 is a perspective view showing a fourth embodiment of the planting nail.

To explain the overall structure of the hay transplanter in FIG. 1, a planting part C is detachably attached to the rear end of the traveling device A via a work implement mounting device B, and the planting part C is attached to the planting mission. A seedling mounting table 16 is arranged above the case 13, a chain case 14 is projected from the planting mission case 13 to the rear, a planting arm 15 is arranged at the rear end of the chain case 14, and the planting arm 15 is provided. The planting claw 9 of the present invention is provided at the tip. Then, power is input to the planted mission case 13 via the transmission shaft 11 from the PTO shaft projecting rearward from the rear surface of the traveling device A, and the seedling table 16 is reciprocated from the planted mission case 13. By rotating the planting arm 15 in synchronism with the reciprocating movement, the tip of the planting claw 9 is rotated in an elliptical shape, and a certain amount of rush seedlings on the seedling mounting table 16 are cut and planted on the rice field. Of.

As shown in FIGS. 2 and 3, the base 9a of the planting claw 9 is bolted to the tip of the planting arm 15 as shown in FIGS. 2 and 3. It is fixed in place and is divided into two parts from the center part of the planting claw 9 and the tip parts 9b and 9b are formed in a fork shape to facilitate cutting of grass seedlings. A push rod 12 is provided in the planting arm 15 below the planting claw 9 so as to be capable of retracting, and the push rod 12 has a U-shaped front end, which extends to the side of the tip 9b. Since the side receiving plate 12a and the rear receiving plate 12b projecting obliquely upward and rearward from the lower portion of the side receiving plate 12a are provided, and the side receiving plate 12a and the rear receiving plate 12b form the receiving portion D. is there.

Therefore, when the planting arm 15 is rotated and the rush seedling E is cut off from the seedling mounting table 16 by the planting claw 9, the rush seedling E is received by the receiving portion D and is received by the side receiving plate 12a. The lateral support plate 12b prevents the grass seedlings E from being smoothly received by the rear receiving plate 12b on a long surface, and the planting arm 15 rotates downward to move the receiving portion D into the soil. When the push push rod 12 is extended and the grass seedling E is pushed out, the grass seedling E is not broken and is not damaged.

Further, as another structure for preventing the rush seedling E from being damaged when pushed out by the push rod 12, as shown in FIGS. 4 and 5, the structure of the planting claw 9 is divided into two as in the above.
