Description

Pitaya grafting stock slotting tool

Technical Field

The utility model belongs to the technical field of the dragon fruit grafting, especially, relate to a dragon fruit grafting stock slotting tool.

Background

At present, the method for cultivating the dragon fruit nursery stock mainly comprises cuttage, grafting, seedling sowing and the like. The cutting seedling raising has the advantages of simple technical requirements, easy maintenance of the characteristics and properties of excellent varieties, poor resistance, large using amount of cutting slips and the like; although the seedling sowing and seedling raising has strong root system and strong resistance, the seedling raising speed is slow, the fruiting is slow, the offspring variation is large, and the large-scale production is not facilitated. The advantages of the seedling and the cutting seedling are fully exerted by grafting and seedling raising, the respective defects are avoided, and the method has the advantages of strong root system, strong stress resistance, wide adaptability, quick seedling formation, early fruiting and the like. The grafting variety of the dragon fruit is various, and the grafting can be divided into surface healing and deep healing from the position of wound healing. The most common grafting flat grafting is surface healing. The surface layer has the defects of poor healing degree, quick water loss, firmness and the like. Deep healing on the contrary solves the above mentioned problems very well. The grooving grafting can enable the healing points of the scion and the stock to be in the grooved, so that the effect of deep healing is achieved, the water loss is less, the healing degree is high, and the mode that the scion is embedded into the grooved is firmer. The slotting grafting can be used for grafting scions by slotting on the top or the side of a drill, but no corresponding slotting tool is available for simply and quickly slotting the drill at present.

SUMMERY OF THE UTILITY MODEL

The utility model discloses to the not enough of above-mentioned prior art, invented a dragon fruit grafting stock slotting tool.

In order to achieve the above object, the utility model adopts the following technical scheme:

a dragon fruit grafting stock slotting cutter comprises a cutter holder, a U-shaped blade, screws, nuts and mounting grooves, wherein the cutter holder is provided with the through mounting grooves, and two sides of the top of the U-shaped blade are outwards extended to be provided with side wings; the bottom of the U-shaped blade penetrates through the mounting groove from top to bottom and the side wing is fixed on the cutter holder through a screw and a nut.

The utility model discloses a slotting tool adopts the design of U type blade, just can dig out the groove of grafting scion in the top or the side meat layer of brill wood after the cutting of U type blade.

Furthermore, the bottom of the U-shaped blade is arranged obliquely forwards, and the bottom of the U-shaped blade is contacted with the drilled wood firstly when the groove is dug, so that the U-shaped blade realizes point cutting to linear cutting, the point cutting is easier to break through a waxy cortex of the drilled wood, and the operation is more labor-saving; meanwhile, the front end of the dug groove is an inclined surface, so that the grafting scions are not easy to pull out and fall off by the inward-inclined groove clamp after being embedded.

Furthermore, the maximum distance between the cutting edges on the two sides of the U-shaped blade is 2mm, the grafted scion is more tightly extruded and attached to the meat of the stock after being embedded, the healing degree is high, and nutrition is more easily transmitted to the scion.

Further, the height of the U-shaped blade is 10-12 mm, the preferential height is 12mm, the height corresponds to the depth of the dug groove, the cutting of the scion is influenced by the too deep depth of the groove, and the scion is unstable and easy to fall off after the scion is grafted because the depth of the groove is too shallow.

Furthermore, the left end and the right end of the tool apron are bent and tilted upwards, so that the tool apron can be conveniently pushed by a hand and can also slide on the top of the drill.

The utility model has the advantages that: the slotting cutter of the utility model can perform slotting grafting scion on the top of the wood drill in the grafting process of the dragon fruit, thereby realizing fast, simple and convenient slotting grafting; if the assembly line mode is adopted for grafting, two pieces of drilling wood can be dug within one minute by one person, the efficiency is 3-4 times higher than that of the old tool, and the size strictness of the groove is ensured; the whole structure is simple, and the practicability is strong.

Detailed Description

The present invention is described in detail below with reference to the accompanying drawings:

in the description of the present invention, it should be noted that the directions or positional relationships indicated by "top", "bottom", "front", "back", etc. are based on the directions or positional relationships shown in the drawings, or the directions or positional relationships usually placed when the products of the present invention are used, and are only for convenience of description and simplification of the description, but do not indicate or imply that the indicated device or element must have a specific direction, be constructed and operated in a specific direction, and thus, should not be construed as limiting the present invention.

As shown in fig. 1 and 3, a dragon fruit grafting stock slotting tool comprises a tool apron 1, a U-shaped blade 2, a screw 3, a nut 4 and a mounting groove 5, wherein the tool apron 1 is provided with the mounting groove 5 which penetrates through, and the mounting groove 5 is located at the rear half part of the tool apron 1 and is located on the central line. The left end and the right end of the tool apron 1 are designed to be tilted upwards, so that the tool apron is convenient to hold by hands and push by hands, and the tool apron 1 can slide on the top of the drill. The two sides of the top of the U-shaped blade 2 extend outwards to form side wings 21, and the bottom of the U-shaped blade 2 penetrates through the mounting groove 5 from top to bottom during mounting and fixes the side wings 21 on the tool apron 1 through screws 3 and nuts 4.

The bottom of the U-shaped blade 2 of the embodiment is arranged obliquely forwards, and the bottom of the U-shaped blade 2 is arranged obliquely forwards as shown in fig. 2, so that the purpose is to realize point cutting during cutting of the wood drilling waxy cortex, the labor is saved, the front end of the dug groove is oblique, and the scion is not easy to fall off after grafting. When the U-shaped blade 2 is designed, a design mode of being narrow at the bottom and wide at the top is adopted, the maximum distance between the tops (the distance between the two side wings) is 6mm, and the width of the arc part at the bottom is 4 mm; the height H of the U-shaped blade 2 is 30 mm.

The using method comprises the following steps: holding the two ends of the tool apron 1 by one hand, flatly placing the tool apron 1 on the top surface of the drill, then contacting the front end of the bottom of the U-shaped blade 2 with a waxy cortex layer of the drill, then advancing for a certain distance, and finally tilting the front end of the tool apron 1 to pick out the meat quality of the part cut by the U-shaped blade 4.

Although particular embodiments of the present invention have been described and illustrated in detail, it should be noted that various changes and modifications could be made to the above-described embodiments without departing from the spirit of the invention and the scope of the appended claims.
