Description

Technical Field

[0001] The utility model relates to the technical field of grafting, and particularly to a device for splitting a rootstock and a grafting device having the same. Background Art

[0002] In order to maintain certain excellent characteristics of plants, certain methods must be used to inherit these excellent characteristics. At present, due to the increasingly prominent problem of continuous cropping obstacles of melons, grafting technology has attracted more and more attention. Professional seedling growers and seedling companies have emerged as the times require.

[0003] Grafting is one of the artificial vegetative propagation methods of plants, that is, a branch or bud of one plant is grafted onto the stem or root of another plant, so that the two parts grafted together grow into a complete plant. The grafted branch or bud is called a scion, and the grafted stem or root is called a rootstock. Generally, a seedling with 2 to 4 buds is selected as the scion, which becomes the upper part or top of the plant after grafting. The rootstock becomes the root system part of the plant after grafting.

[0004] In the process of grafting, it is necessary to split the grafting end of the rootstock to form a grafting seam for the scion to insert. Splitting the rootstock is an important link related to the success rate of grafting. For professional seedling growers and seedling companies, the splitting of the rootstock is mostly carried out manually. Affected by human factors, the differences in the grafting seams are relatively large, resulting in the inability to guarantee the success rate of grafting. Moreover, safety accidents such as scratches are likely to occur during the splitting process. Therefore, there is an urgent need to provide a device for splitting the rootstock.

Detailed implementation manners

[0030] In the following description, a large number of details are provided to enable a thorough understanding of the present utility model. However, those skilled in the art can understand that the following description only exemplarily shows the preferred embodiments of the present utility model, and the present utility model can be implemented without one or more such details. In addition, in order to avoid confusion with the present utility model, some well-known technical features in the art are not described in detail.

[0031] According to one aspect of the present utility model, a rootstock splitting device is provided. The rootstock splitting device can split the grafting end of the rootstock to form a grafting seam for the scion to be inserted. Therefore, the rootstock splitting device can provide a basis for subsequent grafting processes. The rootstock splitting device can be applied to any suitable equipment, including but not limited to grafting equipment. Therefore, according to another aspect of the present utility model, a grafting equipment is also provided. The rootstock splitting device and the grafting equipment of the embodiments of the present utility model will be described in detail below with reference to the accompanying drawings.

[0032] As Figure 2-5 shown, the rootstock splitting device 100 can include a tool assembly 200 and a claw opening assembly 300.

[0033] Combined with Figure 1 and 6 shown, the tool assembly 200 can be used to split the grafting end of the rootstock 400 so that a grafting seam can be formed inside the grafting end. The tool assembly 200 can adopt any suitable tool, including but not limited to a splitting knife, as long as it can form a grafting seam on the grafting end.

[0034] In order to facilitate the splitting, the grafting end of the stock 400 usually needs to be fixed. In some embodiments, the grafting end of the stock 400 can be fixed by the first clamping jaw 510. Specifically, the first clamping jaw 510 can be opened, the stock 400 can be clamped on the first clamping jaw 510, and then the first clamping jaw 510 can be closed, so that the grafting end of the stock 400 can be clamped and fixed. In this way, when the tool assembly 200 is splitting, the first clamping jaw 510 can suppress the deviation of the grafting end, thereby improving the consistency of the grafting seam, and the quality of the splitting seam is higher. The first clamping jaw 510 may include a pneumatic clamping jaw, an electric clamping jaw, or a hydraulic clamping jaw, etc.

[0035] The jaw opening assembly 300 can be used to open the first jaw 510. Specifically, under the action of the jaw opening assembly 300, the first jaw 510 can be opened, thereby forming a joint space. Due to the joint space, the scion can slightly open the grafting seam, so that it can be inserted into the grafting seam more smoothly. Therefore, the joint space can usually be smaller, as long as it can meet the insertion of the scion. Therefore, compared with the opening amplitude of the first jaw 510 when clamping the rootstock 400, the opening amplitude of the first jaw 510 at this time can be smaller. In this way, during the process of inserting the scion into the grafting seam, the first jaw 510 can still play a good limiting role on the grafting end, thereby still suppressing the deviation of the grafting end. During the grafting process, if the first clamping jaw 510 can be opened to a predetermined angle to form a joint space, the scion can be inserted into the grafting seam more easily. If the first clamping jaw 510 itself is used to ensure that the stock 400 is clamped and opened to a predetermined angle, the performance requirements of the first clamping jaw 510 will be very high. Therefore, in this solution, the formation of the joint space is achieved through the action of the clamping jaw opening component 300, that is, the joint space is not formed by the first clamping jaw 510 itself, so the cost of the first clamping jaw 510 will be reduced, thereby reducing the overall cost of the stock splitting device 100. Therefore, the use of the clamping jaw opening component 300 is a relatively cost-saving solution that makes the overall stock splitting device 100 more concise and reliable. When the clamping jaw opening component 300 cancels the action on the first clamping jaw 510, the first clamping jaw 510 can be restored to a closed state by relying on its driving unit or its own rebound performance. The clamping jaw opening component 300 can use any suitable component, such as a cylinder component or a motor component, as long as the first clamping jaw 510 can be opened. The jaw opening assembly 300 may act on the first jaw 510 in any manner, including but not limited to pressing.

[0036] In practical applications of the rootstock splitting device 100, the first jaw 510 can fix the grafting end of the rootstock 400. The tool assembly 200 can split the grafting end of the rootstock 400 to form a grafting seam inside the grafting end. Before the scion is inserted into the grafting seam, the jaw opening assembly 300 can act on the first jaw 510, so that the first jaw 510 can be opened by a small amplitude to form a joint space. In this way, after the scion is inserted into the grafting seam, the scion can slightly expand the grafting seam, so that it can be inserted into the grafting seam more smoothly.

[0037] In summary, the rootstock splitting device 100 provided by the embodiment of the present utility model can automatically split the rootstock, so that manual operation is not required. In this way, the rootstock splitting device 100 can avoid labor costs and prevent safety accidents such as scratches. Moreover, due to the absence of the influence of human factors, the consistency of the grafting seams is relatively high, so that the success rate of grafting can be improved. In addition, the working efficiency of splitting the rootstock is relatively high, so that the efficiency of grafting can be improved.

[0038] In an embodiment where the rootstock splitting device 100 is applied to a grafting device, as Figure 1 and 6 shown, the grafting device may further include a rootstock clamping device 500. The rootstock clamping device 500 may include the above-mentioned first jaw 510. In this way, the grafting device can make the consistency of the grafting seams relatively high, so that the success rate of grafting can be improved.

[0039] The first jaw 510 can adopt any suitable jaw as long as it can fix the grafting end of the rootstock 400. In some embodiments, the first jaw 510 can be a Y-shaped jaw. The Y-shaped jaw can include a 30-degree jaw or jaws at any other suitable angle. A convex block 511 can be provided on the Y-shaped jaw. When the convex block 511 is acted on by the jaw opening assembly 300, the Y-shaped jaw can be opened to form a joint space. When the tool assembly 200 splits the grafting end of the rootstock 400, the Y-shaped jaw can provide a relatively large clamping force, so that the deviation of the grafting end can be better suppressed. Moreover, since the inner side of the Y-shaped jaw can still support the grafting end when it is opened, during the process of inserting the scion into the grafting seam, the limiting effect of the Y-shaped jaw on the grafting end is relatively good. In addition, the convex block 511 can facilitate the action of the jaw opening assembly 300 to facilitate the formation of a joint space.

[0040] Exemplarily, the grafting device may further include a second jaw 520. The second jaw 520 may be used to fix the non-grafted end of the rootstock 400. That is to say, the second jaw 520 and the first jaw 510 may be independent jaws, and the two can be opened and closed separately. Specifically, the first jaw 510 and the second jaw 520 can be opened, the rootstock 400 can be clamped onto the first jaw 510 and the second jaw 520, and then the first jaw 510 and the second jaw 520 can be closed, so as to clamp and fix the grafted end and the non-grafted end of the rootstock 400 respectively. The second jaw 520 and the first jaw 510 can clamp different positions of the rootstock 400, so as to improve the effect of fixing the rootstock 400, further inhibit the offset of the rootstock 400, and thus can further improve the consistency of the grafting seam and the quality of the split seam is higher. Since the rigidity of the rootstock is usually not very high, it is particularly important to fix the rootstock at different positions. Moreover, when the jaw opening assembly 300 opens the first jaw 510, the second jaw 520 can also fix the rootstock 400, so as to inhibit the offset of the grafting seam, and then ensure that the scion can be smoothly inserted into the grafting seam, ensuring a relatively high success rate of grafting.

[0041] The second jaw 520 may include a pneumatic jaw, an electric jaw or a hydraulic jaw, etc. The structures of the second jaw 520 and the first jaw 510 may be the same or different. Exemplarily, the second jaw 520 may be a parallel jaw. In this way, the second jaw 520 and the first jaw 510 can clamp the rootstock 400 in different directions respectively, so as to further improve the stability of fixing the rootstock 400.

[0042] Returning to the rootstock splitting device 100, as Figure 2-5 shown, the jaw opening assembly 300 may include an opening driving member 310 and an abutting member 320. The abutting member 320 may be connected to the driving end of the opening driving member 310. Under the driving of the opening driving member 310, the abutting member 320 can move, so as to abut against the first jaw 510, and then the first jaw 510 can be opened to form a seam space. In the embodiment where there is a convex block 511 on the Y-shaped jaw, the abutting member 320 can abut against the convex block 511. The opening driving member 310 includes but is not limited to a motor, a cylinder or a hydraulic cylinder. With such a setting, the structure of the jaw opening assembly 300 is relatively simple and convenient for manufacturing. Moreover, the opening driving member 310 can control the moving distance of the abutting member 320, so as to abut the first jaw 510 to open by different amplitudes, and then can control the size of the seam space. In this way, the rootstock splitting device 100 can meet different grafting requirements and has strong applicability.

[0043] Exemplarily, the abutting member 320 may include a fixing portion 321 and a rolling portion 322. The rolling portion 322 is rotatably sleeved on the fixing portion 321. The driving end of the opening driving member 310 may be connected to the fixing portion 321. In this way, the opening driving member 310 can drive the rolling portion 322 to move through the fixing portion 321. Under the drive of the opening driving member 310, the rolling surface 323 of the rolling portion 322 can rollingly abut against the first jaw 510, so that the first jaw 510 can form a seam space. In this way, during the process that the rolling portion 322 abuts against the first jaw 510, the rolling surface 323 can roll on the first jaw 510 to form rolling friction, thereby reducing the frictional force and wear.

[0044] Exemplarily, the abutting member 320 may include a cam follower. The inner ring of the cam follower and the mounting shaft connected to the inner ring may be the fixing portion 321. The driving end of the opening driving member 310 may be connected to the mounting shaft. The outer ring of the cam follower may be the rolling portion 322. The outer peripheral surface of the outer ring of the cam follower may be the rolling surface 323. With such a setting, the abutting member 320 can adopt a standard part, so that there is no need for separate design, and the design amount of the rootstock splitting device 100 is reduced.

[0045] Exemplarily, the opening driving member 310 may include a slide cylinder. The slide cylinder can drive the abutting member 320 to move linearly. In an embodiment where the first jaw 510 includes a Y-shaped jaw, the moving direction of the abutting member 320 is different from the opening direction of the Y-shaped jaw, and the rolling surface 323 of the rolling portion 322 can rollingly abut against the Y-shaped jaw. The slide cylinder can ensure the smooth movement of the abutting member 320 and relatively high torsional strength. Moreover, the stop position of the slide cylinder is limited, so that the position of the abutting member 320 can be ensured to be accurate, and further the size of the seam space can be accurately controlled.

[0046] Exemplarily, the tool assembly 200 may include a splitting driving member 210 and a tool mechanism 220. The tool mechanism 220 may be connected to the driving end of the splitting driving member 210. Under the drive of the splitting driving member 210, the tool mechanism 220 can move along the extending direction of the grafting end to form a grafting seam in the grafting end. The splitting driving member 210 includes but is not limited to a motor, a cylinder or a hydraulic cylinder. The tool mechanism 220 includes but is not limited to a splitting tool mechanism, as long as it can form a grafting seam. With such a setting, the structure of the tool assembly 200 is relatively simple and convenient for manufacturing.

[0047] Exemplarily, the tool mechanism 220 may include a connecting member 221, a telescopic driving member 222, and a tool 223. The connecting member 221 may be connected between the driving end of the split seam driving member 210 and the main body of the telescopic driving member 222. In this way, the split seam driving member 210 can drive the telescopic driving member 222 and the connecting member 221 to move synchronously along the extension direction of the grafting end. The split seam driving member 210 includes, but is not limited to, a motor, a cylinder, or a hydraulic cylinder. The tool 223 may be connected to the driving end of the telescopic driving member 222. Driven by the telescopic driving member 222, the tool 223 can move between the extended position and the retracted position along the telescopic direction. Among them, when the tool 223 is in the extended position, it can be located outside the connecting member 221. When the tool 223 is in the retracted position, it can be located inside the connecting member 221. The connecting member 221 may include a frame, a baffle, or any other suitable structure. With such an arrangement, when the tool 223 is in the retracted position, the connecting member 221 can protect the tool 223, thereby preventing personnel from being accidentally injured by touching the tool 223. Under the action of the split seam driving member 210, the tool 223 in the extended position can move along the extension direction of the grafting end to form a grafting seam. The telescopic direction may be perpendicular to the extension direction of the grafting end. The telescopic driving member 222 includes, but is not limited to, a motor, a cylinder, or a hydraulic cylinder. The tool 223 includes, but is not limited to, a splitting knife, as long as it can form a grafting seam.

[0048] In practical applications, the tool 223 can usually be in the retracted position. When split seam is required, the telescopic driving member 222 can drive the tool 223 to move along the telescopic direction to the extended position. Then, the split seam driving member 210 can drive the telescopic driving member 222 and the tool 223 to move toward the grafting end along the extension direction of the grafting end, so that the tool 223 can be inserted into the grafting end, thereby forming a grafting seam. The telescopic driving member 222 can drive the tool 223 to move along the telescopic direction to the retracted position, so that the tool 223 can leave the grafting end. Then, the split seam driving member 210 can drive the telescopic driving member 222 and the tool 223 to move away from the grafting end along the extension direction of the grafting end to return to the initial position, thereby preparing for the next split seam.

[0049] Exemplarily, the connecting member 221 may include a connecting seat 224 and a protection plate 225. The protection plate 225 may be connected to the connecting seat 224. The connecting seat 224 may be connected between the driving end of the split seam driving member 210 and the main body of the telescopic driving member 222. When the tool 223 is in the retracted position, it can be located at the rear side of the protection plate 225. The "rear side" can generally be the side facing away from the personnel. In this way, the protection plate 225 can effectively protect the personnel from being accidentally injured. When the tool 223 is in the extended position, it can extend out of the protection plate 225. The structure of this connecting member 221 is relatively simple and convenient for processing and manufacturing.

[0050] Exemplarily, the tool assembly 200 may further include a base 230 and a stopper 240. The main body of the split seam driving member 210 and the stopper 240 may both be connected to the base 230. When forming the grafting seam, the connecting member 221 may abut against the stopper 240. Through the limiting effect of the stopper 240 on the connecting member 221, the tool 223 can be driven into the expected position within the grafting end, so that an expected grafting seam can be formed. In this way, the consistency of the grafting seam is higher and the success rate of grafting is higher. The stopper 240 may adopt various types of stoppers known in the art or that may appear in the future, including but not limited to a baffle or a stop block. In some embodiments, the stopper 240 may include a combination of a hydraulic buffer stopper and a hard stopper. When the connecting member 221 is about to reach the position, it may first contact the hydraulic buffer. The hydraulic oil damping in the hydraulic buffer can buffer and decelerate the connecting member 221. And when the tool 223 is driven into the expected position within the grafting end, the connecting member 221 may abut against the hard stopper, so that it can stop moving.

[0051] Exemplarily, in an embodiment where the jaw opening assembly 300 includes an opening driving member 310 and an abutting member 320, the jaw opening assembly 300 may further include a mounting plate 330. The mounting plate 330 may be connected between the base 230 and the main body of the opening driving member 310. With such an arrangement, the jaw opening assembly 300 and the tool assembly 200 can be connected together.

[0052] Exemplarily, a linear guide 250 may further be provided on the base 230. The linear guide 250 may extend along the extending direction of the grafting end. Driven by the split seam driving member 210, the connecting member 221 is slidably connected to the linear guide 250. The linear guide 250 can improve the stability and linearity of the movement of the tool 223, thereby improving the quality of the grafting seam.
