Description

TECHNICAL FIELD

[0001] The utility model relates to the technical field of agronomy grafting, more particularly to an agronomic auxiliary grafting device. BACKGROUND

[0002] In agricultural production, grafting technology is an important horticultural means, widely used in the propagation and improvement of fruit trees, ornamental plants and vegetables. Through grafting, the scion of excellent varieties (such as high yield, disease resistance, high quality, etc.) can be combined with the stock of strong roots (such as strong roots, strong resistance, etc.), forming new plants, so as to realize the improvement of varieties and the improvement of yield. However, the traditional grafting method often relies on manual operation, which is low in efficiency, and the fixation and protection of the grafting part have many challenges.

[0003] The limitations of traditional grafting method are as follows:

[0004] Single fixation method: traditional grafting method usually uses binding, clamping and other methods to fix the grafting part, but these methods often have the problems of loose fixation and easy loosening, especially in windy and rainy weather, the grafting part is easy to be damaged, which affects the survival rate of grafting.

[0005] Observation and management are not convenient: after traditional grafting, the grafting part is often wrapped in binding material or soil, which is not convenient for horticultural workers to observe its growth state at any time. Once the grafting part appears abnormal, such as infection of bacteria, poor growth, etc., it is difficult to find and handle in time, resulting in grafting failure.

[0006] Poor adaptability: different plants and different parts of grafting need different fixation methods and angles. Traditional grafting method often cannot meet the needs of different grafting, resulting in poor grafting effect. INVENTION CONTENTS

The clamping assembly is adjusted by moving the threaded rod 603 in the threaded sleeve 601, so as to achieve good fixation of the grafting part.

[0033] The clamping assembly comprises an arc-shaped plate 607 fixedly connected with the piston cylinder 604, an air bag cushion layer 608 fixedly connected at the inner end of the arc-shaped plate 607, a non-woven fabric cushion layer 609 covered at the inner end of the air bag cushion layer 608, a matching piston block 605 slidingly installed at the inner side of the piston cylinder 604, a compression spring 606 fixedly connected between the piston block 605 and the threaded sleeve 601, and an inflation hole formed in the arc-shaped plate 607 and in communication with the air bag cushion layer 608 through the piston cylinder 604. The air in the piston cylinder 604 is extruded into the air bag cushion layer 608 through the inflation hole by extruding the piston block 605 by the threaded rod 603, so as to make the air bag cushion layer 608 expand, and in turn, the grafting part is fixed more gently. The non-woven fabric cushion layer 609 increases the friction to prevent relative sliding, and the air bag cushion layer 608 can adapt to grafting parts of different shapes.

[0034] The rotating mechanism 3 comprises a rotating plate 301 located at the outer side of the mounting plate 2, a matching rotating column 302 rotatably installed in the rotating hole, and the rotating column 302 is fixedly connected with the grafting cylinder 1 and the rotating plate 301 at both ends. A hidden groove is formed at the end of the rotating plate 301 close to the mounting plate 2, a matching clamping ball 303 is movably installed at the opening of the hidden groove, a compression spring 304 is fixedly connected between the clamping ball 303 and the bottom wall of the hidden groove, a plurality of semispherical clamping grooves 8 are arranged in an annular array on the outer wall of the mounting plate 2, and the semispherical clamping grooves 8 are matched with the clamping ball 303.

[0035] The telescopic rod 4 comprises an inner rod fixedly connected with the mounting plate 2 and an outer cylinder fixedly connected with the base 5, and the inner rod is slidingly installed in the outer cylinder.

[0038] When the technical personnel observes that the grafting part grows well and does not need to be fixed through the grafting cylinder 1, the rotating block 602 can be reversely rotated to loosen the grafting part by the clamping assembly, and then the grafting cylinder 1 can be removed.

[0039] The above is only a preferred specific embodiment of the utility model; however, the protection scope of the utility model is not limited to this. Any skilled person in the art can make equivalent replacement or change according to the technical scheme and improvement concept of the utility model within the technical range disclosed by the utility model, which should be covered in the protection scope of the utility model.
