Description

Technical Field

[0001] This utility model relates to the field of grafting, and in particular to an auxiliary grafting device for custard apple. Background Technology

[0002] Custard apples are produced in summer and autumn, with the autumn harvest being the main focus. The flowering period is from late spring, around May to June, when pollination occurs. The fruiting period is from June to November, during which time the fruit is harvested, packaged, and prepared for sale. Grafting is one of the artificial propagation methods for plants. Grafting methods are divided into branch grafting and bud grafting. During grafting, the cambium layers of the scion and rootstock should be tightly connected to ensure the scion survives. The branch or bud that is grafted is called the scion; the plant being grafted is called the rootstock. After grafting, the scion and rootstock should be immediately wrapped together with plastic film.

[0003] However, in the existing technology, the grafting process of custard apple tree trunks is carried out by manual visual inspection and manual grafting operation, which makes it difficult to control the grafting quality and the bacteria on the hands can easily contaminate the cut surface of the grafted tree trunk. Utility Model Content

[0004] The technical problem to be solved by this utility model is to provide an auxiliary grafting device for custard apples. The technical solution of this utility model to solve the above-mentioned technical problem is as follows:

[0005] A custard apple grafting aid includes an opening and closing locking unit. Two positioning and anti-deviation units are installed on the inner side of the opening and closing locking unit. A grafting trunk is provided between the two positioning and anti-deviation units. Two grafting cut surface positioning units are installed on the upper end face of the opening and closing locking unit. The two positioning and anti-deviation units and the grafting cut surface positioning units are symmetrically installed relative to the grafting trunk. A grafting wrapping unit is installed at the rear end of the opening and closing locking unit. The opening and closing locking unit includes a locking rod. Connecting strips are installed on the outer sides of both ends of the locking rod. The rear ends of the two connecting strips are respectively rotatably connected to a first swing strip and a second swing strip.

[0006] The grafting cut surface positioning unit includes a cut surface guide clamp, a transmission frame is fixedly installed on the front end face of the cut surface guide clamp, and an adjustment rod is installed on the inner side of the bottom end of the transmission frame.

[0007] Preferably, the positioning and anti-deviation unit includes a double-headed positioning seat. A connecting bent rod is fixedly installed at one end of the upper surface of the double-headed positioning seat. A limiting diagonal strip is rotatably connected to the outer side of the middle part of the connecting bent rod. Both ends of the double-headed positioning seat are provided with toothed blocks. The grafted tree trunk is installed by engaging the two ends of the two double-headed positioning seats with the toothed blocks. The upper surface of the grafted tree trunk is provided with a tree trunk cross section. The upper ends of the two limiting diagonal strips are in close contact with the tree trunk cross section.

[0008] Preferably, the grafting and wrapping unit includes an installation column, a film roll placement box is installed on the outside of the installation column, a cover plate is threaded to the upper end of the film roll placement box, a film outlet is provided on the rear end face of the film roll placement box, the bottom end of the installation column passes through the cover plate and the film roll placement box in sequence and is fixedly connected to the first swing bar, the film roll placement box is rotatably connected to the installation column, a film roll is provided between the film roll placement box and the installation column, and the film roll is sleeved on the outside of the middle part of the installation column.

[0009] Preferably, the rear ends of the first swing bar and the second swing bar are rotatably connected by a mounting post, and the first swing bar, the second swing bar and the two connecting bars are symmetrically installed relative to the locking rod. The rear end of the locking rod passes through the connecting bar located at the front end of the second swing bar and is connected to the connecting bar located at the front end of the first swing bar by a thread.

[0010] Preferably, the first and second swing bars are slidably connected to the two transmission frames and the slit guide plate, the surfaces of the first and second swing bars are provided with scale lines, the adjusting rod passes through the first and second swing bars and is threadedly connected to the transmission frame, and the first and second swing bars are rotatably connected to the two adjusting rods.

[0011] Compared with the prior art, the present invention has the following advantages:

[0012] 1. After selecting the grafting trunk, the trunk is cut to form a cross-section. Then, the opening and locking unit drives two positioning and anti-deviation units and the grafting cut surface positioning unit to fit onto the outside of the grafting trunk. The two limiting diagonal strips can initially position the whole. When the locking rod rotates, it drives the first swing bar and the second swing bar to swing back and forth through the two connecting bars. Then, the first swing bar and the second swing bar synchronously drive the two positioning and anti-deviation units and the grafting cut surface positioning unit to move towards each other. The double-headed positioning seat and the limiting diagonal strips can keep the whole fixed to the grafting trunk, avoiding the whole from deflecting or vertically displacing relative to the grafting trunk. The cut surface guide plate is adjusted according to the grafting position, so that when the two adjusting rods rotate relative to the first swing bar and the second swing bar, they drive the cut surface guide plate to slide linearly through the transmission frame. The surfaces of the first swing bar and the second swing bar are equipped with scale lines, so that the position of the cut surface guide plate can be precisely adjusted.

[0013] 2. Two cutting guide plates guide and limit the blade, facilitating rapid cutting of the grafting surface on the grafted trunk. This allows for precise control of the position and depth of the grafting surface. After the grafting surface is formed, the locking rod is rotated in the opposite direction to keep the double-headed positioning seat loose from the grafted trunk. Then, the grafted branch is inserted into the grafting surface, and the entire unit is rotated clockwise. As the locking unit rotates relative to the grafted trunk, the film roll in the film roll box is output through the film outlet, achieving a rotating wrapping operation for the grafted trunk and grafted branch. This effectively reduces the difficulty of grafting, improves the grafting quality, and avoids contact between the hands and the cut surface, thus preventing contamination of the cut surface by bacteria from the hands.

[0019] The specific embodiments of this utility model will be further described below with reference to the accompanying drawings. It should be noted that these descriptions are for the purpose of aiding understanding of this utility model, but do not constitute a limitation thereof. Furthermore, the technical features involved in the various embodiments of this utility model described below can be combined with each other as long as they do not conflict with each other.

[0020] like Figure 1 and Figure 2As shown, the present invention provides an auxiliary grafting device for custard apples, comprising an opening and closing locking unit 1. Two positioning and anti-deviation units 2 are installed on the inner side of the opening and closing locking unit 1, with a grafting trunk positioned between the two positioning and anti-deviation units 2. Two grafting cut surface positioning units 3 are installed on the upper surface of the opening and closing locking unit 1. The two positioning and anti-deviation units 2 and the grafting cut surface positioning units 3 are symmetrically installed relative to the grafting trunk. A grafting wrapping unit 4 is installed at the rear end of the opening and closing locking unit 1. The opening and closing locking unit 1 includes a locking rod 104, with connecting strips 103 installed on the outer sides of both ends of the locking rod 104. The rear ends of the two connecting strips 103 are rotatably connected to first swing strips 101. The first swing bar 101, the second swing bar 102, and the two connecting bars 103 are symmetrically installed relative to the locking rod 104. The rear end of the locking rod 104 passes through the connecting bar 103 located at the front end of the second swing bar 102 and is connected to the connecting bar 103 located at the front end of the first swing bar 101 by a thread. When the locking rod 104 rotates, it drives the first swing bar 101 and the second swing bar 102 to swing relative to each other through the two connecting bars 103. In turn, the first swing bar 101 and the second swing bar 102 synchronously drive the two positioning and anti-deviation units 2 and the grafting cut surface positioning unit 3 to move towards each other, so as to fix the whole on the outside of the grafted tree trunk.

[0021] As a preferred technical solution in this embodiment, such as Figures 1 to 3 As shown, the positioning and anti-deviation unit 2 includes a double-headed positioning seat 201. A connecting bent rod 203 is fixedly installed at one end of the upper surface of the double-headed positioning seat 201. A limiting diagonal strip 202 is rotatably connected to the outer side of the middle part of the connecting bent rod 203. Both ends of the double-headed positioning seat 201 are provided with toothed blocks. The grafted trunk is installed by engaging the two ends of the double-headed positioning seats 201 with the toothed blocks. The upper surface of the grafted trunk is provided with a trunk section. The upper ends of the two limiting diagonal strips 202 are in close contact with the trunk section. The double-headed positioning seat 201 and the limiting diagonal strips 202 can keep the whole fixed to the grafted trunk, and prevent the whole from deflecting and vertically displacing relative to the grafted trunk.

[0022] As a preferred technical solution in this embodiment, such as Figure 1 and Figure 2As shown, the grafting cut positioning unit 3 includes a cut guide clamp 303. A transmission frame 302 is fixedly installed on the front end face of the cut guide clamp 303. An adjusting rod 301 is installed on the inner side of the bottom end of the transmission frame 302. The first swing bar 101 and the second swing bar 102 are slidably connected to the two transmission frames 302 and the cut guide clamp 303. The surfaces of the first swing bar 101 and the second swing bar 102 are provided with scale lines. The adjusting rod 301 passes through the first swing bar 101 and the second swing bar 102 and is connected to the transmission frame 302 by a thread. The first swing bar 101 and the second swing bar 102 are rotatably connected to the two adjusting rods 301. By precisely adjusting the position of the cut guide clamp 303, the blade is guided and limited by the two cut guide clamps 303, which facilitates the blade to quickly cut the grafting cut on the grafting trunk and effectively controls the position and depth of the grafting cut.

[0023] As a preferred technical solution in this embodiment, such as Figure 3 and Figure 4 As shown, the grafting wrapping unit 4 includes a mounting post 403. A film roll placement box 401 is mounted on the outside of the mounting post 403. The upper end of the film roll placement box 401 is connected to a cover plate 402 by a thread. The rear end face of the film roll placement box 401 is provided with a film outlet 404. The bottom end of the mounting post 403 passes through the cover plate 402 and the film roll placement box 401 in sequence and is fixedly connected to the first swing bar 101. The rear ends of the first swing bar 101 and the second swing bar 102 are rotatably connected through the mounting post 403. The film roll placement box 401 is rotatably connected to the mounting post 403. A film roll is provided between the film roll placement box 401 and the mounting post 403. The film roll is sleeved on the outside of the middle part of the mounting post 403. When the opening and closing locking unit 1 drives the grafting wrapping unit 4 to rotate clockwise relative to the grafted tree trunk, the film roll in the film roll placement box 401 is output through the film outlet 404 and realizes the automatic rotation and wrapping operation of the grafted tree trunk and grafted branches.

[0024] In summary, when grafting a custard apple tree, after selecting the grafting trunk, the trunk is cut to form a cross-section. Then, the opening and closing locking unit 1 drives two positioning and anti-deviation units 2 and the grafting cut surface positioning unit 3 to fit onto the outside of the grafting trunk. Specifically, the limiting oblique strip 202 swings relative to the double-headed positioning seat 201 through the connecting bent rod 203, so that the upper end of the limiting oblique strip 202 is in close contact with the cross-section of the trunk. Thus, the two limiting oblique strips 202 can perform preliminary positioning of the whole. The rear end of the locking rod 104 passes through one of the connecting strips 103 and is connected to the other connecting strip 103 by threads. When the locking rod 104 rotates, it drives the first swing strip 101 and the second swing strip 102 to swing relative to each other through the two connecting strips 103. Thus, the first swing strip 101 and the second swing strip 102 synchronously drive the two positioning and anti-deviation units 2 and the grafting cut surface positioning unit 3 to move towards each other.

[0025] Both ends of the double-headed positioning seat 201 are provided with toothed blocks, which can be engaged with the surface of the tree trunk by means of the toothed blocks at both ends of the two double-headed positioning seats 201. In this way, the double-headed positioning seat 201 and the limiting inclined strip 202 can keep the whole fixed to the grafted tree trunk, and prevent the whole from deflecting or vertically displacing relative to the grafted tree trunk. The cutting guide clamp 303 is adjusted according to the grafting position, so that when the two adjusting rods 301 rotate relative to the first swing bar 101 and the second swing bar 102, the cutting guide clamp 303 is driven to slide linearly through the transmission frame 302. The surfaces of the first swing bar 101 and the second swing bar 102 are provided with scale lines, so the position of the cutting guide clamp 303 can be precisely adjusted.

[0026] Two guide plates 303 guide and limit the blade, facilitating the rapid cutting of the grafting surface on the grafted trunk. This allows for precise control of the position and depth of the grafting surface. After the grafting surface is formed, the locking rod 104 is rotated in the opposite direction to keep the double-headed positioning seat 201 loose from the grafted trunk. Then, the grafted branch is inserted into the grafting surface, and the whole thing is rotated clockwise. As the locking unit 1 opens and closes, the grafting wrapping unit 4 rotates relative to the grafted trunk. The film roll in the film roll placement box 401 is output through the film outlet 404, realizing the rotation and wrapping operation of the grafted trunk and grafted branch. This effectively reduces the difficulty of grafting, improves the grafting quality, and avoids contact between the hands and the cut surface, thus preventing contamination of the cut surface by bacteria from the hands.

[0027] The embodiments of this utility model have been described in detail above with reference to the accompanying drawings, but this utility model is not limited to the described embodiments. For those skilled in the art, various changes, modifications, substitutions, and variations can be made to these embodiments without departing from the principles and spirit of this utility model, and these variations still fall within the protection scope of this utility model.
