Spike wood front end cutting mechanism for camellia oleifera seedling grafting

Abstract

The invention provides a scion wood front end cutting mechanism for camellia oleifera seedling grafting. The scion wood front end cutting mechanism comprises a cutting device, a supporting table, a guide plate and a workbench. The guide plate is provided with a tilt; and the large end of the inverted-L-shaped notch faces the direction opposite to the cutting direction of the cutting device. A transmission connecting plate is driven by an air cylinder to move, and therefore under the combined action of a sliding block, a linear bearing and a spring, a cutting blade is made to be tightly attached to'lt 'on a guide plate in the moving process. The purpose of rapidly cutting the front end of the scion wood into a smooth wedge-shaped notch is achieved.

Description

Technical Field

[0001] The present invention relates to the technical field of grafting equipment, and particularly relates to a cutting mechanism for the front end of scions used for grafting oil-tea camellia seedlings. Background Art

[0002] As an important woody oil plant, oil-tea camellia is widely planted in the Yangtze River Basin and various places in South China in our country. The main industries of oil-tea camellia are almost all located in our country, and there is very little relevant research abroad. In order to cultivate high-quality seedlings, grafting technology is currently widely used in the cultivation process of oil-tea camellia seedlings. At present, the grafting of improved oil-tea camellia seedlings in our country mainly relies on manual labor. Manual grafting has problems such as high labor intensity, low operation efficiency, difficult-to-guarantee survival rate, and high operation costs, which seriously restrict the development of the oil-tea camellia industry in our country. There is an urgent need to develop grafting machinery for improved oil-tea camellia seedlings.

[0003] Although many mature fruit and vegetable grafting machines have been developed at present, they are not suitable for the cleft grafting method of oil-tea camellia seedlings. According to the information consulted, at present, only the Harbin Institute of Forestry Machinery, State Forestry Administration and the Research Institute of Forestry New Technology, Chinese Academy of Forestry Sciences are jointly researching grafting machinery for oil-tea camellia seedlings. During the cleft grafting process, the front end of the scion branch needs to be cut into a smooth wedge shape, which is an important link in the grafting process of oil-tea camellia seedlings. The scheme adopted by the cutting mechanism for the front end of the scion of the Harbin Institute of Forestry Machinery, State Forestry and Grassland Administration is that multiple actuators act simultaneously to push two cutting knives arranged in a V shape to cut longitudinally, but multiple actuators need to be controlled simultaneously, and the control system is complex. Summary of the Invention

[0004] The present invention aims at the above problems and provides a cutting mechanism for the front end of scions used for grafting oil-tea camellia seedlings.

[0005] In order to achieve the above object, the technical solution adopted by the present invention is: The present invention provides a cutting mechanism for the front end of scions used for grafting oil-tea camellia seedlings, including a cutting device, a support table, a guide plate, and a workbench; the support table is fixed on the workbench, and its front view projection is in the shape of a "Ji", and there is a square hole at the center of the upper end surface; the cutting device is arranged below the support table; the guide plate is fixed to the position of the square hole at the center of the upper end surface of the support table by screws, and there is a "<"-shaped notch at its center position, the large end of which faces the opposite direction to the cutting direction of the cutting device, and there is also a trapezoidal groove along the horizontal direction at the center position on the large end side of the "<"-shaped notch on its upper surface.

[0006] Furthermore, the cutting device includes a slide rail, a slider, a smooth shaft, a linear bearing, a spring, a tool holder, a cutting knife, a transmission connection plate, and a cylinder; except for the transmission connection plate and the cylinder fixed on the workbench, all parts of the cutting device are placed in pairs and are symmetric about the horizontal axis of the support table.

[0007] The two guide wheels are fixed on both sides of the driving wheel shaft, and the two guide wheels are fixed on both sides of the driving wheel shaft, and the two guide wheels are fixed on both sides of the driving wheel shaft.

[0008] Furthermore, the angle range of the “<”-shaped notch on the guide plate is 10 degrees to 30 degrees.

[0009] The beneficial effect of the present invention is that a smooth wedge-shaped cut can be quickly cut at the front end of the tassel wood by only cooperating with a pneumatic cylinder and a mechanical mechanism without causing other damage to the tassel wood. BRIEF DESCRIPTION OF THE DRAWINGS
