A kind of oblique cutting test device for hard branch grafted seedlings of forest fruit

Abstract

The present invention designs a test device for bevel cutting of hard branch grafted seedlings installed on a universal material testing machine, relates to the technical field of agricultural machinery, and consists of a frame, a cutting mechanism, a seedling clamping mechanism, a seedling cutting support mechanism and a bevel Angle adjustment mechanism composition. The frame includes a support base plate, frame longitudinal rods and frame beams, and rotates the entire frame to different angles around the connecting axis of the base to realize continuous adjustment of the bevel angle; the cutting mechanism includes an optical axis, a cutter fixing plate and a cutter, through The cutter fixing plate and bolts are used to replace and fix the cutters with different parameters; the seedling clamping mechanism includes a pair of seedling clamping vise; the seedling cutting support mechanism includes left and right seedling support sliders and connecting plates, which can be adjusted 1. The width and position of the gap formed by the right seedling support slider; the device is installed on the universal material testing machine through the optical axis and the base connecting shaft, and is suitable for the test of forest fruit and hard branch grafted seedlings with different diameters and hardness.

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 grafting technology of forest fruits is more and more popular among producers, mainly because the grafting technology of forest fruits is the best way to produce virus-free seedlings. 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 character...

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.
