A cutting joint device for automatic grafting of seedlings

Abstract

The invention discloses a cutting and joining device for seedling automatic grafting, which comprises a bracket, a cutting and joining mechanism arranged on the bracket, and a rootstock moving mechanism. The cutting and joining mechanism is provided with a fixed seat and a moving seat, and the moving seat is arranged on Above the fixed seat, the fixed seat is connected with the bracket, and the bottom of one end of the movable seat is provided with a grafting blade, and the movable seat is driven to move up and down to drive the grafting blade to move to complete the cutting action; The wood support assembly is provided with the front support of the earwood and the rear support of the earwood. The front support of the earwood is driven by the cylinder to move up and down; the support assembly of the rootstock is provided with the front support of the rootstock and the rear support of the rootstock. The mechanisms are connected, and the rootstock moving mechanism drives the front support of the rootstock to move up and down. The device can realize reliable cutting of rootstock and earwood as well as accurate and fast joining.

Description

technical field [0001] The invention relates to a grafting machine, specifically a cutting and joining device for automatic grafting of seedlings, which is used for cutting and joining of seedling branches, thereby completing the grafting process. Background technique [0002] Grafting is one of the methods of artificial propagation of plants. Grape grafting technology is an emerging technology. The use of machines for automatic grafting seedlings has a high survival rate and high production efficiency. However, the research on automatic grafting machines in my country started relatively late. In recent years, individual agricultural universities and research institutes in China have begun to study fruit trees. Automatic grafting equipment has made some progress, but due to many factors such as low degree of automation, complex structure, difficult maintenance and adjustment, the promotion and application are more restricted. [0003] The rural areas of our country are activ...

AI Technical Summary

Problems solved by technology

[0008] First of all, the movement of the cutting and joining process is relatively complicated, the operation chain is long, the grafting efficiency is not high, and the time interval between cutting and joining is long, and the water loss at the incision of the grafted seedlings affects the survival of the grafted seedlings to a certain extent. Secondly, both rootstock and earwood have a certain degree of flexibility, and the position of the incision after cutting has a certain deviation. Through the movement of the rootstock support platform or the earwood support platform, the joint of the rootstock and earwood incision sometimes deviates and cannot be smoothly joined , which affects the grafting efficiency; third, the structure of the clamping device and the V-shaped pneumatic cutting and transportation device are relatively complicated, and the processing and assembly costs are relatively high
