Forest fruit hard branch grafting seedling beveling testing device

Abstract

The invention relates to a forest fruit hard branch grafting seedling beveling testing device and relates to the technical field of agricultural machines. The device is composed of a rack, a cutting mechanism, a seedling clamping mechanism, a seedling cutting and supporting mechanism and a beveling angle adjusting mechanism. The rack comprises a supporting bottom plate, a rack longitudinal rod and a rack beam. The rack is rotated to different angles around a base connecting shaft so that continuous adjustment of the beveling angle can be achieved. The cutting mechanism comprises an unthreaded shaft, a cutter fixing plate and a cutter. The cutter fixing plate and a bolt are used for replacing and fixing cutters with different parameters. The seedling clamping mechanism comprises a pair of seedling clamping flat tongs. The seedling cutting and supporting mechanism comprises a left seedling supporting slider, a right seedling supporting slider and a connecting plate, and the width and the position of a gap formed by the left seedling supporting slider and the right seedling supporting slider can be adjusted. The device is installed on a universal material testing machine through the unthreaded shaft and the base connecting shaft and is suitable for testing forest fruit hard branch grafting seedlings in different diameters and hardness degrees.

Description

technical field [0001] The invention relates to the technical field of agricultural machinery, in particular to a test device installed on a universal material testing machine to obliquely cut hardwood grafted seedlings of forest fruits. Background technique [0002] Grafting is to transplant a part of a plant's organs (such as branches and buds) to another plant, so that the two can heal and grow into a new individual. Production practice has proved that the self-rooted seedlings (cuttings, layering) of forest fruit cultivars have exposed their limitations, and the fruit grafting technology is more and more popular among producers. It is an important method, and the virus-free seedlings of forest fruits are an important measure to improve product quality. At present, domestic fruit grafting is dominated by manual green branch grafting, which has the characteristics of low efficiency, low survival rate of grafting, and high labor intensity. In foreign countries, hard branc...

Problems solved by technology

[0005] At present, in various cutting tests, due to the different test objects and test parameters, the designed cutting test devices vary widely, and the versatility for different seedlings is very low.

At the same time, most cutting tests only test the biomechanical properties of the test objects, and pay less attention to the influence of different cutting parameters on the smoothness of the cutting surface. Therefore, most of the existing test devices are used for cutting seedlings or stems Finally, the overall flatness of the cutting surface is low, which cannot meet the test requirements for studying the influence of different cutting parameters on the flatness of the cutting surface.

[0006] The key technology of the oblique cutting test of fruit hardwood grafted seedlings is that the parameters of the oblique cutting can be adjusted, and at the same time, it can prevent the overall low level of the cutting surface. The experimental device for oblique cutting of hardwood grafted seedlings of forest fruits can not only satisfy the adjustable test parameters, but also has good versatility, and can prevent the overall low flatness of the cutting surface, so as to meet the requirements of the research on the impact of different cutting parameters on the flatness of the cutting surface.
