Description

Technical Field

[0001] The invention relates to a grafter, in particular to a grafter suitable for large-diameter rootstocks. Background Art

[0002] The existing clamp-type grafter is suitable for grafting branches with smaller diameters. For large-diameter stock, the incision is made at the edge of the stock, and there are often multiple incisions along the circumference of the stock. The existing grafter is not suitable for grafting such large-diameter stock. At present, grafting such large-diameter stock is done by manually cutting the grafting interface at the edge of the stock with a knife, but knife cutting is laborious and inefficient. Moreover, cutting the grafting interface with a knife also poses a safety problem if excessive force is used. Summary of the invention

[0005] Furthermore, the clamp includes a screw rod threadedly connected to the lower part of the vertical rod of the gantry, an arc-shaped hoop plate arranged on one end of the screw rod located inside the gantry, and a second handle arranged on one end of the screw rod located outside the gantry, and the arc-shaped hoop plate is rotationally matched with the end of the screw rod.

[0006] Furthermore, a sleeve is provided in the middle of the outer arc surface of the arc hoop plate, a circular flange cooperating with the sleeve is provided on the end of the screw rod, and an end cover is provided at the end of the sleeve to prevent the circular flange from escaping from the sleeve.

[0007] Furthermore, anti-skid sharp teeth are arranged on the bottom surface of the anti-skid plate.

[0008] Furthermore, a semi-cylindrical friction-reducing protrusion in contact with the lever is arranged on the upper end surface of the rectangular sliding sleeve.

[0009] Beneficial effects of the present invention:

[0010] The vertical cutting grafter of the present invention is fixed on the stock pile by a hoop, and the cutter is pushed downward by a lever to cut the grafting incision. It can adapt to stock piles of different diameters, and after cutting an incision, the cutter and the sliding cutting guide seat can be conveniently rotated around the shaft rod to another grafting part of the stock to perform the next cutting, which has the advantages of simple and flexible operation, labor-saving cutting, high efficiency, etc. Moreover, compared with cutting the grafting port with a knife, the vertical cutting grafter of the present invention is safer to use.

[0014] The present invention will be further described below in conjunction with the accompanying drawings and embodiments.

[0015] As shown in the figure, the vertical cutting grafter in this embodiment includes a hoop for holding the rootstock, a portal frame 1 and a cutting mechanism. The gantry includes two vertical rods 101 connected to the hoop and a cross rod 102 connecting the two vertical rods. The cutting mechanism includes a shaft rod 2, a sleeve 3, a pin 4, a lever 5, a first handle 6, a cutter 7 and a sliding guide seat 8. The shaft rod is vertically fixed to the middle part of the cross rod, the sleeve is rotatably matched with the upper end of the shaft rod, the pin is vertically arranged on the outer side of the sleeve, one end of the lever is hinged to the pin, and the other end of the lever is connected to the first handle. A rectangular groove 9 is arranged on the lever. The sliding guide seat includes a guide plate 801 for guiding the cutter to move downward and an anti-skid plate 802 connected to the lower end of the guide plate. The upper end of the guide plate is arranged in the rectangular groove on the lever and slidably matches the rectangular groove, and the upper end of the guide plate has a limiting horizontal protrusion 803 to prevent it from sliding out of the rectangular groove. The cutter 7 includes a conductor 701 and a rectangular sleeve 702 arranged at the upper end of the conductor, and the rectangular sleeve is sleeved on the guide plate and slidably matches with the guide plate. In this embodiment, a limiting nut 10 is also provided at the upper end of the shaft rod to prevent the sleeve from falling out.

[0016] In this embodiment, the hoop comprises a screw rod 11 connected to the lower part of the vertical rod of the gantry through a thread, an arc hoop plate 12 provided on one end of the screw rod located inside the gantry, and a second handle 13 provided on one end of the screw rod located outside the gantry, and the arc hoop plate is rotatably matched with the end of the screw rod. Of course, in different embodiments, the structure of the hoop can also adopt other forms.

[0017] In this embodiment, a ring sleeve 14 is provided in the middle of the outer arc surface of the arc hoop plate, a circular flange matching with the ring sleeve is provided on the end of the screw rod, and an end cap 15 is provided at the end of the ring sleeve to prevent the circular flange from falling out of the ring sleeve. This structure allows the end of the screw rod to rotate flexibly in the ring sleeve, while preventing the arc hoop plate from falling off from the end of the screw rod.

[0018] The vertical cutting grafter in this embodiment is used by placing the crossbar of the gantry on the end face of the stock pile 16, then clamping and fixing the hoop on the stock pile, then placing the anti-slip plate of the sliding cutting guide seat on the end face of the stock pile and making the cutter close to the bark part, and finally pushing the cutter down by the lever to cut a grafting incision at one time. The vertical cutting grafter in this embodiment can adapt to stock piles of different diameters, and after cutting an incision, the cutter and the sliding cutting guide seat can be conveniently rotated around the shaft rod to another grafting part of the stock for the next cutting, which has the advantages of simple and flexible operation, labor-saving cutting, high efficiency, etc.

[0019] As an improvement to the above embodiment, anti-skid sharp teeth 804 are provided on the bottom surface of the anti-skid plate. The provision of the anti-skid sharp teeth can better ensure that the position of the sliding cutting guide seat is stable and immobile during the process of pushing the cutter downward.

[0020] As an improvement to the above embodiment, a semi-cylindrical anti-friction protrusion 703 in contact with the lever is provided on the upper end surface of the rectangular sleeve. This improvement enables the rectangular sleeve to slide smoothly along the lever when the lever pushes the cutter downward.

[0021] Finally, it should be noted that the above embodiments are only used to illustrate the technical solution of the present invention rather than to limit it. Although the present invention has been described in detail with reference to the preferred embodiments, those skilled in the art should understand that the technical solution of the present invention can be modified or replaced by equivalents without departing from the purpose and scope of the technical solution of the present invention, which should be included in the scope of the claims of the present invention.
