A grafting device for fruit trees

Abstract

This utility model discloses a grafting device for fruit trees, comprising: a male hoop plate, with studs fixed on both the front and rear sides of the left end of the male hoop plate; a female hoop plate, located on the left side of the male hoop plate and movably passing through the studs, with a nut threaded onto the outside of the studs and tightly fitted to the left end of the female hoop plate; a retaining seat, fixed to the right end of the male hoop plate; a binding strap assembly, installed on the left end of the female hoop plate; and a retaining strip, connected to the binding strap assembly and engaging with the retaining seat. The male and female hoop plates are fitted together and fixed onto the fruit tree branch. Pulling the retaining strip unwinds the binding strap from outside the winding wheel, tightening the spring. The binding strap is then wrapped around the grafted bud on the fruit tree branch. Finally, the retaining strip on the female hoop plate side engages with the retaining seat on the male hoop plate side. This securely binds the grafted bud to the fruit tree branch, preventing separation of the grafted bud from the graft union on the fruit tree branch.

Description

Technical Field

[0001] This utility model relates to the field of fruit tree grafting technology, and in particular to a fruit tree grafting device. Background Technology

[0002] Grafting is one of the methods of asexual reproduction in fruit trees. It involves taking a branch or bud from a superior variety of plant and attaching it to a suitable part of another plant, allowing the two to combine and form a new plant. In traditional fruit tree grafting, the graft union is mainly tied manually using materials such as plastic film and tape. This method carries the risk of insecure binding, easy loosening or breakage, and difficulty in maintaining stable and even pressure at the junction of the grafted bud and the rootstock, thus affecting callus formation. Utility Model Content

[0003] The purpose of this invention is to overcome the shortcomings of the prior art and provide a grafting device for fruit trees to solve the problems mentioned in the background art.

[0022] like Figures 1-3 As shown, a grafting device for fruit trees includes:

[0023] Male hoop plate 1, with studs 11 fixed on both the front and rear sides of the left end of the male hoop plate 1;

[0024] The female hoop plate 2 is located to the left of the male hoop plate 1 and passes through the stud 11. The stud 11 is externally threaded with a nut 22 that is tightly attached to the left end of the female hoop plate 2. The female hoop plate 2 has through holes 21 on both the front and rear sides of the right end. The left part of the stud 11 passes through the through holes 21. The stud 11 of the male hoop plate 1 can pass through the through holes 21 of the female hoop plate 2. Then the nut 22 is screwed into the outside of the stud 11 until it is tightly attached to the female hoop plate 2. In this way, the male hoop plate 1 and the female hoop plate 2 can be used to fix and fit on the branches of the fruit tree.

[0025] Card holder 4, the card holder 4 is fixed to the right end of the male hoop plate 1, the card holder 4 has slots 41 at both the front and rear ends, and the slots 41 have card holes 42 at both the upper and lower ends of the inner wall of the slots 41.

[0026] The strap assembly 5 is installed at the left end of the mother hoop plate 2. The strap assembly 5 includes a strap box 51, a reel 52, and a strap 53. The strap box 51 is fixed to the mother hoop plate 2. The reel 52 is rotatably connected inside the strap box 51. The strap 53 is wrapped around the outside of the reel 52. The end of the strap 53 moves through the side of the strap box 51 and is fixed to the retaining strip 6. The strap 53 is an elastic strap. When the strap 53 is pulled, the strap 53 is unwound from the outside of the reel 52, and the reel 52 rotates counterclockwise.

[0027] The clip 6 is connected to the binding strap assembly 5, engages with the clip seat 4, and inserts into the slot 41. Both ends of the clip 6 have spring grooves 61, and a clip block 63 is slidably connected inside the spring groove 61. A spring 62 is fixed between the clip block 63 and the bottom of the spring groove 61. The clip block 63 is inserted into the clip hole 42. Pulling the clip 6 allows the binding strap 53 to be unwound from outside the winding wheel 52. The binding strap 53 is then wrapped around the grafted bud on the fruit tree branch. Finally, the clip 6 on the female hoop plate 2 side engages with the clip seat 4 on the male hoop plate 1 side, allowing the clip 6 to insert into the slot 41. When the clip 6 is inserted into the slot 41, the clip 63 can be squeezed to move into the spring groove 61 to compress the spring 62. When the clip 6 is inserted into the slot 41 until the clip 63 corresponds to the clip hole 42, the compressed spring 62 can spring the clip 63 to engage with the clip hole 42. This allows the binding strap 53 to stably bind the grafted buds on the fruit tree branch and prevent the grafted buds from separating from the grafting interface on the fruit tree branch. When it is necessary to separate the clip 6 from the clip 4, the clip 63 inserted into the two clip holes 42 can be squeezed at the same time to separate the clip 63 from the clip hole 42, and the clip 6 can be removed from the slot 41.

[0028] Spring assembly 7 is installed at the lower end of strap assembly 5. Spring assembly 7 includes spring box 71, shaft 72 and spring 73. Spring box 71 is fixed at the lower end of strap box 51. Shaft 72 is bearing connected to the middle of spring box 71. The upper part of shaft 72 is fixed to the lower part of winding wheel 52. Spring 73 is installed on the outside of shaft 72. The first and last ends of spring 73 are fixed to the outer wall of shaft 72 and the inner wall of spring box 71, respectively. When winding wheel 52 rotates counterclockwise, it can drive shaft 72 to rotate counterclockwise. In this way, shaft 72 can drive spring 73 to tighten. Spring 73 gives shaft 72 a clockwise restoring force.

[0029] Both the inner ends of the male hoop 1 and the female hoop 2 are fixed with rubber pads 3. When the male hoop 1 and the female hoop 2 are fitted together and fixed on the fruit tree branches, the rubber pads 3 directly contact the fruit tree branches, which can prevent the male hoop 1 and the female hoop 2 from causing damage to the bark of the fruit tree branches.

[0030] Working principle: Place the male hoop plate 1 and the female hoop plate 2 on both sides of the fruit tree branch, and let the stud 11 of the male hoop plate 1 pass through the through hole 21 of the female hoop plate 2. Then screw the nut 22 into the outside of the stud 11 until it is tightly against the female hoop plate 2. The male hoop plate 1 and the female hoop plate 2 can then be fixedly fitted onto the fruit tree branch. Then pull the locking strip 6, which will pull the binding strap 53 from the outside of the winding wheel 52 to unwind it. At this time, the winding wheel 52 will rotate counterclockwise, which will drive the rotating shaft 72 to rotate counterclockwise. This will drive the spring 73 to tighten. The spring 73 will give the rotating shaft 72 a clockwise return force. The binding strap 53 is wrapped around the outside of the grafted bud on the fruit tree branch. Finally, the clip 6 on the female hoop 2 side is engaged with the clip 4 on the male hoop 1 side, so that the clip 6 is inserted into the slot 41. When the clip 6 is inserted into the slot 41, the clip block 63 can be squeezed into the spring groove 61 to compress the spring 62. When the clip 6 is inserted into the slot 41 until the clip block 63 corresponds to the clip hole 42, the compressed spring 62 can spring the clip block 63 to engage with the clip hole 42. In this way, the binding strap 53 can stably bind the grafted bud on the fruit tree branch and prevent the grafted bud from separating from the grafting interface on the fruit tree branch.
