Description

Technical Field

[0001] The utility model discloses a forestry grafting device, which relates to the technical field of grafting devices. Background Art

[0002] Grafting is one of the artificial propagation methods of plants. It is to graft the branches or buds of one plant onto the stem or root of another plant so that the two parts grow into a complete plant. Grafting methods are divided into branch grafting and bud grafting. Grafting is carried out by utilizing the healing function of plants after being injured. It is an important means to improve the growth rate, growth intensity or product quality of crops. During grafting, the cambium of the two wound surfaces is brought close and tied together. As a result, due to cell proliferation, they heal each other and become a whole connected by vascular tissue. In order to ensure the survival rate after grafting, a grafting device is usually used for fixation.

[0003] According to the "A Greening Seedling Grafting Device for Forestry" disclosed in Chinese Patent Publication No. CN216087761U, a clamping plate and a squeezing pad are provided, which clamp the grafted seedlings and the grafted branches, and the device and the grafted seedlings are fixed in a stationary position. Then, under the contraction force of the tension spring, the grafted seedlings and the grafted branches can produce a mutual squeezing effect on the fitting surfaces, which is beneficial to the connection and growth of the two and improves the fixing effect, and will not damage the grafted seedlings and the grafted branches, killing two birds with one stone. A clamping plate and a coil spring are provided, and the staff only needs to turn the left clamping plate to the right when closing the two clamping plates. Due to the structure of the clamping plate, the two clamping plates can be quickly connected and fixed, so that the staff can support the grafted seedlings and the grafted branches with one hand when operating the device, and fix the device with the other hand alone, which reduces the operation difficulty of the device, improves the fixing efficiency, and has strong practicality.

[0004] However, the above device has the problem of clamping and fixing the grafted part by two semicircular clamps. Since the grafted part protrudes outward, it is inevitably not a regular circle, which results in a smaller contact area between the semicircular clamps and the grafted part. The semicircular clamps cannot fit closely with the outer wall of the grafted part over a large area, affecting the fixation effect of the grafted plant. Utility Model Content

[0005] In view of the deficiencies in the prior art, the purpose of the utility model is to provide a forestry grafting device, which can make the grafting part fit tightly with the wrapping groove, thereby improving the fixing effect.

[0006] The purpose of the utility model is achieved in this way:

[0007] A forestry grafting device comprises a main structure and an adjustment structure, wherein the outer wall of the main structure is provided with the adjustment structure;

[0008] The main structure comprises a first limit plate, the outer wall of the first limit plate is fixedly connected with a serrated plate, the first limit plate is clamped with a second limit plate through the serrated plate, the outer wall of the second limit plate is fixedly connected with a fixing box, a threaded barrel is arranged at the bottom of the fixing box, an adjusting screw is threadedly connected inside the threaded barrel, a movable plate is arranged at the bottom of the adjusting screw, and a ratchet plate is fixedly connected to the top of the movable plate;

[0009] The adjustment structure comprises a fixing rod, a moving seat is arranged on the outer wall of the fixing rod, a fixing groove is arranged on the inner wall of the moving seat, and a fixing block is arranged inside the fixing groove.

[0010] Preferably, a guide rod is fixedly connected to the inner bottom wall of the fixed box, and the top of the guide rod passes through the movable plate and is slidably connected to the movable plate.

[0011] Preferably, a socket is provided at one end of the fixing box close to the first limiting plate, and the serrated plate is inserted into the fixing box through the socket and is engaged with the ratchet plate.

[0012] Preferably, the inner walls of the first limiting plate and the second limiting plate are both provided with wrapping grooves, and the outer surfaces of the wrapping grooves are provided with anti-slip sponges.

[0013] Preferably, a return spring is fixedly connected to the inner bottom wall of the fixing groove, and the top of the return spring is fixedly connected to the bottom of the fixing block.

[0014] Preferably, the outer wall of the fixing rod is provided with equidistant positioning grooves, and the shape and size of the positioning grooves are matched with the shape and size of the fixing grooves.

[0015] Preferably, the second limiting plate is fixedly connected to the outer wall of the movable seat.

[0016] Compared with the prior art, the beneficial effects achieved by the utility model are:

[0017] First, by inserting the serrated plate on the first limiting plate into the fixed box through the socket, and rotating the adjusting screw on the fixed box, the adjusting screw drives the movable plate to move upward, and the movable plate drives the ratchet plate to move upward along the guide rod, so that the ratchet plate and the serrated plate are engaged, and the meshing connection between the first limiting plate and the second limiting plate is completed. In this way, the grafted plant is clamped between the first limiting plate and the second limiting plate, so that the grafted part is closely fitted with the wrapping groove, thereby improving the fixing effect.

[0018] Second, by moving the movable seat, the movable seat is made to slide up and down on the fixed rod. When the fixed groove on the movable seat is aligned with the positioning groove on the fixed rod, the return spring in the fixed groove gives the fixed block an outward force, so that the fixed block is disengaged from the fixed groove and inserted into the positioning groove, thereby completing the limited fixation of the movable seat. In this way, the height of the grafting device can be adjusted by moving the movable seat to adapt to grafting in different situations, thereby improving the practicality of the grafting device.

[0029] Through the above technical solution, by inserting the serrated plate 102 on the first limiting plate 101 into the fixed box 104 through the socket, by rotating the adjusting screw 106 on the fixed box 104, the adjusting screw 106 drives the movable plate 107 to move upward, and the movable plate 107 drives the ratchet plate 108 to move upward along the guide rod 109, so that the ratchet plate 108 and the serrated plate 102 are engaged, and the meshing connection between the first limiting plate 101 and the second limiting plate 103 is completed. In this way, the grafted plant between them is clamped by the first limiting plate 101 and the second limiting plate 103, so that the grafted part is closely fitted with the wrapping groove 110, thereby improving the fixing effect;

[0030] By moving the movable seat 202, the movable seat 202 slides up and down on the fixed rod 201. When the fixed groove 203 on the movable seat 202 is aligned with the positioning groove 206 on the fixed rod 201, the return spring 205 in the fixed groove 203 gives the fixed block 204 an outward force, so that the fixed block 204 is disengaged from the fixed groove 203 and is inserted into the positioning groove 206, thereby completing the limited fixation of the movable seat 202. In this way, by moving the movable seat 202, the grafting device can be driven to adjust its height to adapt to grafting under different conditions, thereby improving the practicability of the grafting device.

[0037] Specifically, a return spring 205 is fixedly connected to the inner bottom wall of the fixing groove 203 , and the top of the return spring 205 is fixedly connected to the bottom of the fixing block 204 .

[0038] Through the above technical solution, by providing the return spring 205 , the return spring 205 applies an outward force to the fixed block 204 .

[0039] Specifically, the outer wall of the fixing rod 201 is provided with equidistant positioning grooves 206 , and the shape and size of the positioning grooves 206 match those of the fixing grooves 203 .

[0040] Through the above technical solution, by opening equidistant positioning grooves 206 on the outer wall of the fixed rod 201, the movable seat 202 can be adjusted to an equal distance on the fixed rod 201. By matching the shape and size of the positioning groove 206 with the shape and size of the fixed groove 203, the fixed block 204 can be more easily disengaged and inserted into the positioning groove 206.

[0041] Specifically, the second limiting plate 103 is fixedly connected to the outer wall of the moving base 202 .

[0042] Through the above technical solution, when the movable seat 202 moves, it can drive the second limiting plate 103 to move, complete the adjustment of the height of the grafting device, and improve the practicality of the grafting device.
