A cutting test device for hard branch grafted seedlings of forest fruit based on cutting and sliding cutting

Abstract

The invention provides a testing device installed on a universal material testing machine and used for cutting and sliding cutting of forest fruit hard-twig graft seedlings, and relates to the technical field of agricultural machines. The device comprises a base, a gantry type support, a cutting mechanism and a cutting angle adjusting mechanism. The testing device is installed on the universal material testing machine through a base fixing rod and a polished shaft in the cutting mechanism. The cutting mechanism comprises a cutter, a cutter clamping part, the polished shaft and a polished shaft connection part. Cutters with different parameters are fixed and the sliding cutting angles of the cutters are adjusted through the cutter clamping part and bolts. The cutting angle adjusting mechanism can achieve cutting of the seedlings at different angles and can adjust the size and the position of a seam formed by an upper seam control element and a lower seam control element, and the situation that the overall flatness degree of the cutting faces of the seedlings is low is prevented. Thus, the test parameters of the device are adjustable, universality is good, influences of different cutting parameters on the flatness degree of the cutting faces can be researched, and the testing device is suitable for hard-twig graft testing of the forest fruit seedlings with different diameters and hardnesses.

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 for cutting and sliding cutting of fruit and hard branch grafted seedlings. 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 countri...

Problems solved by technology

[0004] 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.
