Description

Technical Field

[0001] This utility model relates to the field of agricultural planting technology, and in particular to a device for fixing and clamping grafted vegetable seedlings. Background Technology

[0002] Vegetable grafting seedling fixing and clamping structures are key devices used in agricultural production to ensure that the rootstock and scion are accurately fitted and stably fixed during the grafting process, thereby improving the grafting survival rate. The core function of the vegetable grafting seedling fixing and clamping structure is to provide appropriate clamping force and support stability without damaging the seedling tissue, while adapting to the morphological differences of different types of vegetable seedlings.

[0003] Existing vegetable grafting seedling fixing and clamping structures mostly adopt modular and adaptive designs. The modular structure breaks down the device into independent components such as the base, clamping arms, and fixing heads. For example, a "V-groove" is used to fix upright-stemmed vegetables, while a "ring-shaped wrapping" structure is used to fix vining-stemmed vegetables.

[0004] Existing vegetable grafting seedling fixing and clamping structures are usually made of hard plastic and connected by flexible metal. Since the roots and stems of vegetable grafting seedlings are delicate, fixing them with plastic claws may cause marks or damage at the grafting site. In addition, the plastic claws wrap around the roots and stems, affecting the air permeability of the roots and stems, thus affecting the quality and survival rate of vegetable grafting. Utility Model Content

[0005] To overcome the problem that existing vegetable grafting seedling fixing and clamping structures are usually made of hard plastic and connected by elastic metal, which may cause marks or damage to the grafting site due to the tender roots and stems of vegetable grafting seedlings, and the plastic clamps also affect the air permeability of the roots and stems, thus affecting the quality and survival rate of vegetable grafting.

[0006] The technical solution of this utility model is as follows: a vegetable grafting seedling fixing and clamping structure device, including a first claw, a first connecting rod, a support ring, a second connecting rod, and a second claw. The first connecting rod is fixed to the end of the first claw, and the second connecting rod is fixed to the end of the second claw. The support ring is clamped to the side wall between the first and second connecting rods. A connecting block is fixed to the side wall of the second connecting rod. An installation groove is opened on the side wall of the first connecting rod. A clamping block is fixed to the end of the first claw. A clamping groove is opened at the end of the second claw near the clamping block. A first pad is fixed to the inner side wall of the first claw and the clamping block. A second pad is fixed to the inner side wall of the second claw. A plurality of third through grooves are opened on the side wall of the first claw, and a plurality of fourth through grooves are opened on the side wall of the second claw.

[0007] Furthermore, the first and second claws are symmetrically distributed, the locking block is engaged in the middle of the locking groove, and the surfaces of the first and second pads are both honeycomb-shaped, which improves the water storage capacity of the surfaces of the first and second pads.

[0008] Furthermore, the first claw, the first connecting rod, and the locking block are fixedly connected to form an integral structure, and the second connecting rod, the second claw, and the connecting block are fixedly connected to form an integral structure.

[0009] Furthermore, two circular grooves are formed on the side wall of the second connecting rod near the mounting groove, and both circular grooves are connected to the mounting groove.

[0010] Furthermore, two rotating shafts are fixed on the side wall of the connecting block. The rotating shafts are symmetrically distributed and are connected to the middle of the mounting groove in sequence, which improves the stability of the rotation of the first and second jaws.

[0011] Furthermore, the support ring is ring-shaped, and both ends of the support ring are fixed with arc-shaped connecting rods, and the ends of the arc-shaped connecting rods are fixed with support feet.

[0012] Furthermore, a first through groove is provided on the side wall of the first connecting rod, and a second through groove is provided on the side wall of the second connecting rod. The first and second through grooves are symmetrically distributed for the insertion of the arc-shaped connecting rod. A first slot is provided on the side wall of the first connecting rod for the support foot to engage, and a second slot is provided on the side wall of the second connecting rod for the support foot to engage, thereby improving the stability of the support ring installation.

[0013] Furthermore, a support rod is inserted into the middle of the support ring, and the bottom end of the support rod is inserted into the ground, which improves the stability of the grafted seedling planting support.

[0014] The beneficial effects of this utility model are:

[0015] Compared to traditional vegetable grafting seedling fixing and clamping structures, this device improves the convenience of clamping and repositioning through the use of a first claw, a first connecting rod, a support ring, a second connecting rod, and a second claw. The combination of the clamping block and the clamping groove expands the rotation angle of the first and second claws, improving the adaptability of the clamping. The third and fourth through slots reduce the weight of the clamping structure, facilitating liquid flow to the surfaces of the first and second pads. The porous and loose surfaces of the first and second pads facilitate water retention and maintain moisture, thereby improving the quality and survival rate of the vegetable grafting seedlings. Furthermore, the inclusion of a support ring, an arc-shaped connecting rod, a support rod, and support feet enhances the convenience of repositioning the first and second claws. The combination of the support rod and support ring improves the stability of the grafted seedling's rootstock. Attached Figure Description

[0022] The present invention will be further described below with reference to the accompanying drawings and embodiments.

[0023] Among the currently discovered feasible technologies, the following are described:

[0024] Vegetable grafted seedlings have slender stems and tender tissues, which means that the fixing and clamping structure must meet multiple requirements. First of all, stability is the foundation. During the grafting operation and healing stage, the structure must ensure that the relative positions of the scion and rootstock are fixed, so that the cambium layers are closely attached and promote the fusion of callus tissue.

[0025] Clip-type fixing structures are widely used and are mainly divided into plastic clips and metal clips. Plastic clips are mostly made of polyethylene or polypropylene, which have the advantages of being lightweight, inexpensive, and rust-proof. The structure is often U-shaped or V-shaped, and the clamping force is generated by the elastic deformation of the clips. During operation, the opening is aligned with the hinge part and pressed to fix it. Metal clips are made of stainless steel and the clamping force is adjusted by spring buckles. They are suitable for large-scale mechanized grafting.

[0026] The binding method is a traditional fixation method, using materials such as plastic strips and hemp rope to manually wrap the seedlings. This method allows for flexible adjustment of the binding strength to suit seedlings of different thicknesses and shapes, and the materials are widely available and inexpensive. However, its operational efficiency is extremely low, consuming a lot of manpower and time, and the manual binding strength is difficult to control precisely, easily resulting in problems such as too tight binding hindering growth or too loose binding causing the grafting site to loosen. It is not suitable for the needs of modern large-scale production.

[0027] The sleeve structure includes: an elastic collar made of silicone or rubber with an inner diameter slightly smaller than the stem diameter. For example, by applying force evenly through ring contraction, the damage rate to cucumber seedlings is less than 1%. However, it is prone to aging with long-term use and needs to be replaced every quarter.

[0028] The development of vegetable grafting seedling fixing and clamping structures, from mechanical fixing to intelligent self-adaptation, and from single function to multidisciplinary integration, reflects the technological leap of agricultural modernization. With the deep application of materials science, artificial intelligence and Internet of Things technologies, clamping structures will continue to innovate towards precision, greenness and intelligence.

[0029] Please refer to Figures 1-5 A vegetable grafting seedling fixing and clamping structure device includes a first claw 1, a first connecting rod 2, a support ring 3, a second connecting rod 4, and a second claw 5.

A snap-fit ​​groove 7 is provided near the end of the snap-fit ​​block 6, so that the snap-fit ​​block 6 can be snapped into the middle of the snap-fit ​​groove 7, thereby facilitating the clamping and deformation of the first snap-fit ​​claw 1 and the second snap-fit ​​claw 5 to adapt to the grafting roots of vegetables of different sizes. A first pad 8 is fixed on the inner side wall of the first snap-fit ​​claw 1 and the snap-fit ​​block 6, and a second pad 9 is fixed on the inner side wall of the second snap-fit ​​claw 5. The surfaces of the first pad 8 and the second pad 9 are both honeycomb-shaped, which improves the water storage capacity of the surfaces of the first pad 8 and the second pad 9. Several third through grooves 16 are provided on the side wall of the first snap-fit ​​claw 1, the second Several fourth through grooves 20 are provided on the side wall of the claw 5. The third through groove 16 and the fourth through groove 20 pass through the first claw 1 and the second claw 5 in sequence to facilitate the replenishment of water and nutrient solution, while reducing the weight of the first claw 1 and the second claw 5, saving materials and reducing the load on the vegetable grafted seedlings. The first pad 8 and the second pad 9 have soft and elastic surfaces, which improves the safety of the vegetable roots and stems, reduces marks and damage, and stores water and nutrient solution to keep the vegetable grafted roots and stems moist, thereby improving the survival rate and quality of vegetable grafting.

[0030] The second connecting rod 4 has two circular grooves 18 on its side wall near the mounting groove 17. Both circular grooves 18 are connected to the mounting groove 17. Two rotating shafts 21 are fixed on the side wall of the connecting block 14. The rotating shafts 21 are symmetrically distributed and are connected to the middle of the mounting groove 17 in sequence, which improves the stability of the rotation of the first pawl 1 and the second pawl 5.

[0031] Both ends of the support ring 3 are fixed with arc-shaped connecting rods 10, and the ends of the arc-shaped connecting rods 10 are fixed with support feet 22. The side walls of the first connecting rod 2 are provided with first through grooves 11, and the side walls of the second connecting rod 4 are provided with second through grooves 13.

The side walls of the first connecting rod 2 are provided with first locking grooves 12 for the support feet 22 to be locked, and the side walls of the second connecting rod 4 are provided with second locking grooves 19 for the support feet 22 to be locked, which improves the stability of the support ring 3 installation. A support rod 15 is inserted in the middle of the support ring 3. The external dimensions of the support rod 15 are adapted to the internal dimensions of the support ring 3. The bottom end of the support rod 15 is inserted into the ground, which improves the stability of the grafted seedling planting support.

[0032] When using this vegetable grafting seedling fixing clamping structure device, after the vegetable grafting seedling is completed, the operator uses their fingers to pinch the first connecting rod 2 and the second connecting rod 4 in sequence, thereby causing the first claw 1 and the second claw 5 to rotate and open around the rotating shaft 21, thus facilitating the placement of the first claw 1 and the second claw 5 on the outer surface of the vegetable seedling grafted rootstock. Then, the first connecting rod 2 and the second connecting rod 4 are released, allowing the first connecting rod 2 and the second connecting rod 4 to return to their original position under the elastic force of the support ring 3, thereby clamping and fixing the grafted seedling with the first pad 8 and the second... The second padding layer 9 has a soft and elastic surface that comes into direct contact with the grafted seedling, thereby improving the safety of the vegetable rootstock clamping and reducing marks and damage. Water is then sprayed on the surfaces of the first claw 1 and the second claw 5 for maintenance. The third through groove 16 and the fourth through groove 20 pass through the first claw 1 and the second claw 5 in sequence to facilitate liquid flow and at the same time reduce the disturbance of the grafted seedling by the weight of the first claw 1 and the second claw 5. The first padding layer 8 and the second padding layer 9 are honeycomb-shaped to facilitate the storage of water and nutrient solution to keep the vegetable grafted rootstock moist, thereby improving the survival rate and quality of vegetable grafting.
