Detailed Description

The structure, principle and operation of the present invention will be further described with reference to the accompanying drawings and specific embodiments, but the scope of the present invention is not limited thereto.

When the plug seedling transplanting operation is carried out, piston rods at two ends of the bidirectional cylinder 2 extend out, parallel push rods 33 fixedly connected with the bidirectional cylinder slide to two ends of a cross beam along guide rails of a cross beam 11 of the bracket 1, the planting force arm 3 moves towards two ends of the cross beam and drives the planting duckbill 4 to rise and lift to a seedling receiving position, and at the moment, the planting duckbill 4 is closed under the action of the closing cylinder 5; after the seedling receiving barrel for planting the duckbilled seedlings 4 receives the seedlings, the piston rod of the bidirectional cylinder 2 retracts to drive the parallel push rod 33 to move along the slide rail of the cross beam 11 in the opposite direction, the planting duckbilled seedlings 4 are driven to move downwards through the planting force arm 3, and meanwhile, the closed cylinder 5 drives the planting duckbilled seedlings 4 to open and put down the plug seedlings under the action of the comprehensive coordination controller, so that the actions of digging holes and planting seedlings are realized; after the planting duckbill 4 is put down to the plug seedling, the bidirectional air cylinder 2 drives the planting force arm 3 to drive the planting duckbill 4 to move upwards, and when the lowest point of the planting duckbill 4 is higher than the plug seedling by a certain distance, the closing air cylinder 5 drives the planting duckbill 4 to close under the action of the comprehensive coordination controller to prepare for receiving the next plug seedling; and the steps are sequentially circulated to complete the transplanting operation of the plug seedlings.

The seedling clamping and seedling carrying are the problems that the closing of planting duckbills is controlled by a mechanical cam and is difficult to overcome, and particularly the problems frequently occur during the high-speed transplanting of plug seedlings. In order to avoid the problem of seedling clamping and seedling carrying caused by the early closing of the planting duckbill 4, the utility model specially ensures that the planting duckbill is closed after rising to a certain distance higher than the plug seedling by means of program control through the comprehensive coordination controller; meanwhile, the utility model adopts the auxiliary closing spring to accelerate the closing speed of the planted duckbilled seedlings so as to ensure the success rate of the seedling receiving of the next plug seedling; under the action of the comprehensive coordination controller, the planting mechanism of the utility model can perform the actions of seedling throwing, seedling receiving, hole digging and seedling planting more coordinately and efficiently.

The embodiment is a preferred embodiment of the present invention, but the present invention is not limited to the above embodiment, and any obvious improvement, replacement or modification which can be made by those skilled in the art without departing from the essence of the present invention belongs to the protection scope of the present invention.
