Technical Field

[0001] The invention relates to the technical field of pear tree grafting, and in particular to a pear tree grafting device and a grafting method thereof. Background Art

[0002] Grafting is a method of reproduction in which the buds or branches of one plant are grafted onto another plant so that the two parts grow into a complete plant. It is often used to increase the yield of high-quality, low-yield plants. Common methods of pear tree grafting include scion grafting, which involves preparing healthy pear seedlings as rootstocks, and then selecting branches of the desired variety of pear trees as scions for grafting.

[0003] When the existing grafting device is in use, the grafted branches are fixed by fixing clamps, which has a certain insufficient fixing effect on the branches. At the same time, when the wind blows, the branches will shake. The existing device lacks a buffer structure, and the shaking of the branches may cause the grafted branches to separate, which is not conducive to the use of the device. Summary of the invention

[0004] The purpose of the present invention is to solve the shortcomings existing in the prior art, such as: fixing the grafted branches by fixing clamps, which has certain shortcomings in the fixing effect of the branches. At the same time, when the wind blows, the branches will shake. The existing device lacks a buffer structure. When the branches shake, the grafted branches may be separated, which is not conducive to the use of the device. A pear tree grafting device and a grafting method thereof are proposed.

[0005] In order to achieve the above object, the present invention adopts the following technical solutions:

[0014] A pear tree grafting method comprises the following steps:

[0015] S1. Connect the grafted pear branches together, put the fixing tube on the outside of the connected branches to fix them, then install the fixing plate on the two grafted branches, install the fixing rod, the mounting block and the fixing plate together, and thread the connecting block with the fixing rod.

Under the elastic force of the connecting spring 8, the two fixing plates 2 are both subjected to a force in the direction of the fixing tube 3, and this force also acts on the branches, thereby squeezing the two branches, so that the branches are more tightly connected together, and the branches are not easy to separate;

[0029] When the wind blows, the branches will shake. The support structure can limit the shaking of the branches. At the same time, the buffer spring 19 and the damper can be used to further buffer the shaking after the limit. Under the premise of avoiding damage to the branches, the stability of the branches is ensured, and the branches connected together are prevented from separating due to shaking, resulting in grafting failure.

[0030] The supporting structure includes a connecting plate 9 fixedly mounted at the bottom end of the mounting platform 1, a connecting tube 10 fixedly connected to the bottom end of the connecting plate 9, a connecting rod 11 slidably connected between the inner walls of the connecting tube 10, the connecting rod 11 extends to the outside of the connecting tube 10, and one end of the connecting rod 11 located outside the connecting tube 10 is slidably connected to a connecting base 12, a buffer block 18 is fixedly connected to the bottom end of the connecting rod 11, a buffer groove 17 corresponding to the buffer block 18 is opened at the top end of the connecting base 12, a buffer spring 19 is fixedly connected to the side wall of the buffer block 18, and one end of the buffer spring 19 away from the buffer block 18 is fixedly connected to the inner wall of the buffer groove 17, a damper is fixedly mounted on each buffer spring 19, and each buffer spring 19 is fixedly connected to the side wall of the buffer block 18 through the damper;

A plurality of fixing bolts are installed on the connecting plate 9, and the connecting plate 9 is fixedly connected to the mounting platform 1 through the fixing bolts, so that the supporting structure can be easily disassembled from the mounting platform 1;

[0034] A pear tree grafting method comprises the following steps:

[0035] S1. Connect the grafted pear branches together, put the fixing tube 3 on the outside of the connected branches to fix them, then install the fixing plate 2 on the two grafted branches, install the fixing rod 4, the mounting block 6 and the fixing plate 2 together, and thread the connecting block 7 with the fixing rod 4. Under the elastic force of the connecting spring 8, the two fixing plates 2 will be subjected to a force in the direction of the fixing tube 3, and this force will also act on the branches, thereby squeezing the two branches and connecting the branches more tightly together;

[0036] S2. Install the support structure and the mounting platform 1 together, and fix the support structure to the ground through the connecting column 13. When the wind blows, the branches shake, and the support structure can limit the shaking of the branches. At the same time, the buffer spring 19 and the damper are used to further buffer the shaking after the limitation, and the stability of the branches is ensured while avoiding damage to the branches, so as to prevent the connected branches from separating due to shaking;

[0037] S3. After the branches have completely grown together, the supporting structure is separated from the mounting platform 1, and the fixing plate 2, the fixing tube 3 and other structures are removed at the same time.

[0038] When the device is used, the grafted pear branches are first connected together, and the fixing tube 3 is sleeved on the outside of the connected branches to fix them. Then the fixing plate 2 is installed on the two sections of the grafted branches, the fixing rod 4, the mounting block 6 and the fixing plate 2 are installed together, and then the connecting block 7 is threadedly connected to the fixing rod 4. Under the elastic force of the connecting spring 8, the two fixing plates 2 will be subjected to a force in the direction of the fixing tube 3, and this force will also act on the branches, thereby squeezing the two sections of the branches, so that the branches are more closely connected together, and the branches are not easy to separate, so that the branches can be bonded together when growing. In addition, the supporting structure is fixed to the ground by the connecting column 13, and the mounting platform 1 is supported by the connecting column 13. When the wind blows, the branches will shake, and the supporting structure can limit the shaking of the branches. At the same time, the buffer spring 19 and the damper are used to further buffer the shaking after the restriction. Under the premise of avoiding damage to the branches, the stability of the branches is guaranteed, and the branches connected together are prevented from separating due to shaking, resulting in grafting failure.
