Description

Technical Field

[0001] This utility model relates to the field of grafting, and in particular to a pretreatment device for grafting rootstock. Background Technology

[0002] In plant grafting techniques, cleft grafting is a commonly used grafting method, widely applied in the cultivation of fruit trees, garden trees, and some ornamental plants. This method involves vertically splitting the cross-section of the rootstock using a clefting knife or grafting chisel, inserting a scion with buds, and achieving healing between the two to eventually form a new plant.

[0003] Although cleft grafting has advantages such as high survival rate and strong bonding, it still has many inconveniences in actual operation, especially in the rootstock treatment stage. When using a chopping knife or grafting chisel to vertically split the rootstock, the risk of tool misalignment during the cut makes it difficult for the operator to apply precise force, easily leading to hand injuries. Therefore, operators are hesitant to make long cuts, making it impossible to complete the splitting operation in one go. To achieve the splitting effect, a hammer or other auxiliary tool is usually needed to further hammer the top of the chopping knife or grafting chisel to enhance the splitting effect. During this process, the operator needs to hold the chopping knife or grafting chisel with one hand to prevent slippage or displacement, while the other hand performs the hammering operation. Coordinating both hands is difficult, the overall process is time-consuming and laborious, and the operation is not convenient, affecting grafting efficiency and safety. Therefore, a rootstock pretreatment device is proposed. Utility Model Content

[0004] The main purpose of this utility model is to provide a pretreatment device for grafting rootstock, which solves the problems of the difficulty of coordinating both hands in the existing cleft grafting process, the time-consuming and laborious overall process, the lack of convenient operation, and the impact on grafting efficiency and safety.

[0005] To solve the above-mentioned technical problems, the technical solution adopted by this utility model is: a grafting rootstock pretreatment device, comprising a rootstock body, and the pretreatment device comprising:

[0006] The frame can be fitted onto the outside of the rootstock body;

[0007] The clamping mechanism consists of multiple clamping units arranged in a ring on the frame, used to clamp the rootstock body in the frame;

[0008] The movable chopping knife is installed vertically in the frame, with its lower blade resting against the top of the rootstock.

[0009] The hammerhead is located on top of the movable chopping blade and can abut against the top of the frame.

[0010] In the preferred embodiment, the frame includes a bottom ring with telescopic holes for installing clamping units, and multiple support rods on the top of the bottom ring with top sleeves on the top of the support rods.

[0011] In a preferred embodiment, the clamping unit includes a telescopic rod that is telescopically disposed in a telescopic hole.

[0012] In the preferred embodiment, a rubber pad is provided on the clamping side of the clamping arc plate.

[0013] In the preferred embodiment, the number of clamping units and support rods are the same, and the clamping units and their corresponding support rods are located on the same vertical line.

[0014] In the preferred embodiment, the clamping unit further includes a hinge seat and a bending rod. The hinge seat is mounted on the support rod, and the bent part of the bending rod is hinged to the hinge seat via a pivot. A push-pull rod is provided at the top of the limiting plate, and a movable groove is provided in the push-pull rod to pass through it laterally. A clearance groove adapted to the push-pull rod is provided below the bending rod, and an abutment rod that movably passes through the movable groove is provided at the bottom end of the clearance groove.

[0015] In the preferred embodiment, a lever is provided at the top of the bent rod.

[0016] In the preferred embodiment, the top sleeve is provided with external threads, and a locking part for locking the clamping unit in the clamping state is threadedly installed.

[0017] The locking part includes a lifting sleeve threaded onto the outside of the top sleeve, and the bottom end of the lifting sleeve is provided with an abutment ring that can abut against the upper part of the bending rod.

Detailed Implementation

[0031] like Figure 1-7As shown, a grafting rootstock pretreatment device includes a rootstock body 6 and the pretreatment device includes: a frame 1, a clamping mechanism 2, a movable splitting blade 4, and a hammer head 5.

[0032] The frame 1 can be fitted onto the outside of the rootstock body 6. The clamping mechanism 2 consists of multiple clamping units arranged in a ring on the frame 1, which are used to clamp the rootstock body 6 in the frame 1, thereby fixing the pretreatment device on the rootstock body 6. The movable chopping knife 4 can be vertically moved up and down in the frame 1, and its lower blade abuts against the top of the rootstock body 6. The hammer head 5 is located on the top of the movable chopping knife 4 and can abut against the top of the frame 1.

[0033] It should be noted that when the rootstock body 6 is not inserted into the frame 1, the bottom end of the movable chopping knife 4 is slightly higher than the clamping mechanism 2.

[0034] With this design, the pretreatment device can be fitted onto the top of the rootstock body 6, and the pretreatment device can be fixed to the top of the rootstock body 6 by the ring-shaped clamping unit, so that the rootstock body 6 is located at its center. At the same time, due to the insertion of the rootstock body 6, it can push the movable chopping blade 4 upward to a certain height. At this time, the movable chopping blade 4 can be split open by pressing down or hammering the hammer head 5. In addition, the insertion height of the rootstock body 6 can be adjusted according to the required splitting depth. The contact relationship between the hammer head 5 and the frame 1 plays a role in limiting the downward splitting.

[0035] In the preferred embodiment, the frame 1 includes a bottom ring 101, on which a telescopic hole 102 for installing a clamping unit is provided. Multiple support rods 103 are provided on the top of the bottom ring 101. The design of the support rods 103 makes it easy for the operator to observe the positional relationship between the movable chopping knife 4 and the rootstock body 6, as well as the chopping situation. A top sleeve 104 is provided on the top of the support rods 103.

[0036] In the preferred embodiment, the clamping unit includes a telescopic rod 201 that is telescopically disposed in the telescopic hole 102. The inner end of the telescopic rod 201 is provided with a clamping arc plate 202, and the outer end is provided with a limiting plate 203. The clamping arc plate 202 is used to clamp the rootstock body 6, and the limiting plate 203 is used to limit its maximum insertion length to prevent it from detaching. A clamping spring 204 is fitted on the outside of the telescopic rod 201. The clamping spring 204 is located between the clamping arc plate 202 and the inner side of the bottom ring 101.

[0037] With this design, the tension of the clamping spring 204 can be used to keep the clamping arc plate 202 in a clamping state, and the clamping state can be released by pulling back.

[0038] In the preferred embodiment, a rubber pad 212 is provided on the clamping side of the clamping arc plate 202. The rubber pad 212 can increase the contact surface with the rootstock body 6 through its own deformation, thereby improving the clamping force and friction, while preventing damage to the rootstock body 6.

[0039] In the preferred embodiment, the number of clamping units and support rods 103 is the same. In this embodiment, there are four clamping units, which are distributed in a ring at equal intervals. The clamping units and the corresponding support rods 103 are located on the same vertical line.

[0040] In a preferred embodiment, the clamping unit further includes a hinge seat 207 and a bending rod 208. The bending rod 208 is specifically V-shaped. The hinge seat 207 is mounted on the support rod 103. The bent part of the bending rod 208 is hinged to the hinge seat 207 via a pivot, so that the movement of its lower part can be controlled by its upper part. A push-pull rod 205 is provided at the top of the limiting plate 203. The push-pull rod 205 has a movable groove 206 that extends laterally through it. A clearance groove 209 that matches the push-pull rod 205 is provided below the bending rod 208. An abutment rod 210 that extends through the movable groove 206 is provided at the bottom of the clearance groove 209.

[0041] With this design, by pressing the upper part of the bending rod 208, the lower part of the abutment rod 210 can move up and down in the movable groove 206, thereby allowing the clamping arc plate 202 to retract and release the clamping state. At the same time, it is convenient to fit the pretreatment device onto the outside of the rootstock body 6.

[0042] In the preferred embodiment, a paddle 211 is provided at the top of the bending rod 208 to facilitate the operator to press it.

[0043] It should also be noted that since there are four clamping units in this embodiment, the operator needs to use both hands to press two levers 211 simultaneously to achieve the effect of pulling back the clamping units at the same time. Therefore, the width of the levers 211 needs to meet the requirement of one hand controlling two.

[0044] In the preferred embodiment, the top sleeve 104 is provided with external threads, and a locking part 3 for locking the clamping unit in the clamping state is threadedly installed, thereby further improving the clamping tightness and improving the stability during the downward splitting process.

[0045] The locking part 3 includes a lifting sleeve 301 threaded onto the outside of the top sleeve 104, and the bottom end of the lifting sleeve 301 is provided with an abutment ring 302 that can abut against the upper part of the bending rod 208.

[0046] With this design, the lifting sleeve 301 can be rotated to move it up and down outside the top sleeve 104, thereby moving the abutment ring 302 to the position of contacting the bending rod 208. This contact relationship with the bending rod 208 improves the tightness of the clamping arc plate 202, and rotating it upwards can release the locking state.

[0047] The inner side of the top sleeve 104 is provided with two symmetrical limiting grooves 105, and both the upper and lower ends of the limiting grooves 105 are open.

[0048] In the preferred embodiment, the movable chopping knife 4 includes a knife body 401. Both sides of the knife body 401 are provided with limiting strips 402 that slide in conjunction with the limiting grooves 105. The bottom end of the limiting strips 402 is provided with an anti-detachment block 403 that is wider than the limiting grooves 105, so that the knife body 401 can move up and down under the limiting action of the limiting grooves 105 and the limiting strips 402. At the same time, the hammer head 5 and the anti-detachment block 403 respectively play the role of limiting up and down.

[0049] In the preferred embodiment, the limiting groove 105 and the telescopic rod 201 are arranged in an alternating manner to avoid conflict between the telescopic rod 201 and the limiting strip 402.

[0050] The above embodiments are merely preferred technical solutions of this utility model and should not be considered as limitations on this utility model. The protection scope of this utility model should be the technical solution described in the claims, including equivalent substitutions of the technical features described in the claims. That is, equivalent substitutions and improvements within this scope are also within the protection scope of this utility model.
