Cutting and jointing device for automatic grafting of seedlings

Abstract

The invention discloses a rootstock and scion support mechanism for automatic grafting, which comprises a scion support assembly and a rootstock support assembly; the rootstock support assembly is provided with a scion front bearing and a scion rear bearing; the scion front bearing and the scion rear bearing are respectively arranged on two sides of a moving seat; the rootstock support assembly isprovided with a rootstock front bearing and a rootstock rear bearing, the rootstock front bearing and the rootstock rear bearing are respectively arranged at two sides below the moving seat; the scion front bearing and the rootstock front bearing are connected with a driving part, and the scion front bearing and the rootstock front bearing are driven to move in the vertical direction. The rootstock and scion support mechanism for automatic grafting is used for supporting and positioning a rootstock and a scion in the operating process of a grafting machine so as to assist in completing the grafting and cutting operation.

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
