Description

Seedlings picking mechanism

Technical field

The present invention relates to planting machinery technical field, a kind of seedlings picking mechanism of transplanter is especially designed.

Background technology

A kind of seedling diffusion by seed plate of transplanter is planted to the equipment on soil.Current transplanter is all had no idea High-density planting is realized, a row amount is typically once planted between two to four plants, its main cause is, under original transplanter Material each of mechanism is individually a set of drive system driving, and cause that the cutting agency in equipment can not lean on is close, so Just have no idea to handle for some crops for needing high density to transplant, it is therefore necessary to improved.

Seedlings picking mechanism is the device that Xia Miao mechanisms are sent to after the seedling crawl for ejecting seedling picking mechanism on transplanter, in order to up to To high-density planting, seedlings picking mechanism is needed comprising multiple seedlings pickings folder, and each seedlings picking folder needs four actions, and first turns to and take Seedling mechanism ejects the position of seed plate, when the second seedling is fallen into seedlings picking folder, and seedlings picking folder is clamped, and the 3rd seedlings picking folder rotates vertical position Put, the 4th seedlings picking folder opens, then the seedling in seedlings picking folder is fallen into Xia Miao mechanisms.If this four actions, each seedling taking clamp Depend on single equipment to drive, such mechanism will become very huge, can not also set the distance between seedling taking clamp Put close.

The content of the invention

The present invention, there is provided a kind of seedlings picking mechanism, can be realized for deficiency of the prior art with a set of drive mechanism The everything of seedlings picking folder.

In order to solve the above-mentioned technical problem, the present invention is addressed by following technical proposals：Seedlings picking mechanism, the seedlings picking Mechanism includes the second rotating shaft, and the second rotating shaft two ends are rotatably connected in the frame, are fixed with and connect in second rotating shaft Seedling clip module, second rotating shaft is provided at both ends with the first pin and the second pin, and the seedlings picking clip module includes second and connect Bar, third connecting rod, fourth link, some seedlings pickings folder and some push rods, the seedlings picking folder include two pieces of intermediate plates and are arranged on two pieces It is provided with before the first bar hole and groove, the block and is provided with block between the intermediate plate, the side wall of the block Shoulder hole, the shoulder hole includes a circular hole and the second bar hole, the circular hole be arranged on it is described face to face before, described the Two bar holes are arranged on the projection being provided with the bottom of the circular hole, the intermediate plate with the fit depressions, the push rod Jacking block including the body of rod and end, the push rod is slidably connected in second rotating shaft, the second connecting rod and the described 3rd Connecting rod, which passes through to be provided with first bar hole, the second connecting rod and the third connecting rod, pushes the intermediate plate to the gear The spring of block, the push rod passes through second bar hole, and the jacking block is engaged with the circular hole, and the fourth link is worn Cross on the top of all blocks, second lever and be provided with lifting member, it is described when the second rotating shaft side is rotated Seedlings picking is pressed from both sides towards the lateral movement of seed plate one, and the push rod rear end is in contact with first lever, and the jacking block is released into the circle Hole, the block is slid down, and the projection is caught in groove, and at this moment the distance between two pieces of described intermediate plates diminish, the seedling It is clamped after seed plate ejection, when second rotating shaft is towards in opposite side rotation process, the seedlings picking is entrainment of seedling Towards lower seedling mechanism kinematic, the fourth link is gradually in contact with the lifting member, and the fourth link is relative to described Lifting member is moved downward, and the lifting member pulls block to move upwards, and the projection is deviate from from the groove, the intermediate plate it Between distance broaden.

Compared with prior art, the beneficial effects of the invention are as follows：Our seedlings picking mechanism has fully used link gear, profit It can allow multiple seedlings picking folders are synchronous to realize everything with a driving equipment, substantially reduce the mutual distance between mechanism, It can thus realize that densification is planted.
