Description

Plug seedling transplanter presss from both sides and gets mechanism Technical Field The utility model relates to the technical field of agricultural machinery, in particular to a clamping mechanism of a plug seedling transplanting machine. Background In the field of modern agricultural planting, ‌ plug seedling transplanting technology ‌ refers to the process of transplanting seedlings cultivated using plug seedling technology into a larger container or soil. The plug seedling technology adopts light matrix soilless materials such as turf, vermiculite and the like, and adopts mechanical precision seeding, one seedling per plug, and one seedling per plug. The seedling raising mode makes the seedling grow in independent space, has complete root system, high survival rate after transplanting and fast and orderly growth and development. The automation demand of plug seedling transplanting operation is growing increasingly, and the performance of the clamping mechanism serving as a core execution component of the transplanting machine directly determines the transplanting efficiency and the seedling survival rate. However, traditional clamping device adopts rigid clamping jaw cooperation straight line drive structure more, and easy the causing epidermis damage when rigid clamping jaw and seedling stem direct contact especially when the fragile plug seedling of centre gripping, and the clamping force is too big can lead to the seedling to break, and the clamping force is not enough then probably to initiate the slippage, and current clamping mechanism is got the plug seedling of damaging easily, and it is poor to get the reliability to the clamp of plug seedling, and this scheme solves this technical problem. Disclosure of utility model Aiming at the defects of the prior art, the utility model provides the clamping mechanism of the plug seedling transplanting machine, which drives the forward and reverse screw rods to move through the high-speed rotation of the motor, the forward and reverse screw rods drive the clamping arms to move oppositely, so that the arc clamping pieces are slowly close to plug seedlings, the clamping of the arc clamping pieces is buffered by the plurality of sponge bosses, the clamping of the plug seedlings by the arc clamping pieces is more stable and reliable through the self-locking effect of the clamping arms and the forward and reverse screw rods, the clamping of the plug seedlings by the arc clamping pieces is flexibly buffered through the sponge bosses, the situation that the plug seedlings are broken due to the stress concentration during clamping is avoided, and the clamping effect of the clamping mechanism on the plug seedlings is better.
