TECHNICAL FIELD

[0001] The utility model belongs to the technical field of agricultural equipment, specifically belongs to a kind of transplanter seedling holder. BACKGROUND

[0002] In the agricultural equipment such as seedling transplanter, seedling holder is often used. When seedling holder clamps seedling, the force needs to be moderate, cannot appear seedling clamping injury situation, also need to prevent the force too small, seedling drop situation;In addition, when seedling is placed, seedling needs to be placed quickly, and cannot be placed in seedling, seedling is clamped again. In summary, the structure design of seedling holder in prior art is prone to inaccurate clamping force control, seedling clamping situation, after the above-mentioned situation occurs, seedling survival rate is affected. SUMMARY

[0003] The utility model provides a kind of transplanter seedling holder to reach the purpose of moderate force of seedling holder, seedling is not clamped after being placed.

[0004] A kind of transplanter seedling holder, including shell, seedling clamp arm, pull plate, return spring and cylinder;

[0005] Cylinder is connected in the shell side, pull plate pull frame is connected in the other side of shell, and the end of pull plate pull frame is connected with two pull plates, the end of pull plate is respectively pinned in seedling clamp arm;The rear side of each seedling clamp arm is pinned in shell, and return spring is further connected between seedling clamp arm.

[0006] Further, the shell is U-shaped, and the cylinder connecting hole is formed in the transverse wall of the U-shaped shell;Through hole and pin hole are formed in one of the walls.

[0007] Further, pin hole is formed in the other wall of the shell, and arc-shaped groove is formed in the inner side of the wall.

[0008] Further, the pull plate pull frame is U-shaped, and the transverse wall of the U-shaped pull plate pull frame is connected to the piston rod, pin shaft is connected between the side walls of the U-shaped pull plate pull frame, and the pull plate is connected to the pin shaft in the recessed groove.

[0009] Further, the recessed groove and the through hole are formed in the inner side of the seedling clamp arm, the pull plate is connected to the pin shaft in the recessed groove, and is contained in the through hole.

[0010] Further, the inner side of the seedling clamp arm is clamped, and the buffer pad is laid.

[0011] The utility model has the advantages that:

[0012] Compared with the seedling clamp in the prior art, the seedling clamp provided by the utility model opens with a larger rear angle and a whole trapezoidal opening space, and the use effect is better than that of the prior art with a nearly triangular opening structure. In addition, the seedling clamp has a reasonable structure design, reduces the situation of taking seedlings after planting seedlings during use, fully considers the durability and service life during the structural design, and therefore is convenient and easy to use, not easy to damage and has a very positive market prospect.

[0019] The technical scheme of the application will be further explained and described below through specific embodiments.

[0020] Referring to the drawings, the utility model provides a kind of transplanting machine seedling clamp, including shell 1, seedling clamp arm 2, pull plate 3, return spring 4 and air cylinder 5;

[0021] The shell 1 is U-shaped, and the air cylinder 5 connecting hole is formed on the transverse wall of the U-shaped shell. A through hole and a pin hole are formed on one of the walls. The through hole design makes it easy to install the internal pin shaft. On the other wall, a pin hole is formed, and an arc-shaped groove is formed on the inner side of the wall.

[0022] A cylinder 5 is connected to one side of the housing 1, and a pulling plate 3 is connected to the piston of the cylinder 5 at the other side of the housing 1. The pulling plate 3 is in the shape of a U, and the horizontal wall of the U is connected to the piston rod. A pin shaft is connected between the two side walls of the U, and the pulling plate 3 is connected to the pin shaft. The other end of the pulling plate 3 is connected to the pin of the seedling clamping arm 2. The inside of the seedling clamping arm 2 is provided with a concave groove and a through hole, and the pin shaft of the pulling plate 3 is connected to the concave groove and accommodated in the through hole. The rear side of each seedling clamping arm 2 is connected to the housing 1, and a return spring 4 is further connected between the seedling clamping arms 2. A buffer pad is arranged at the clamping position of the inside of the seedling clamping arm 2.

[0023] In use, the piston of the cylinder 5 is actuated to drive the pulling plate 3, and the pulling plate 3 pulls the seedling clamping arm 2 to open and close the seedling clamping arm 2, thereby achieving the functions of taking and placing seedlings.
