Description

Conifer seed grafting cutter

Technical Field

The utility model relates to a grafting technical field, concretely relates to conifer kind grafting cutter.

Background

At present, with the increasing of the eating amount of natural green organic food, the improvement of the industrialization degree and the increasing of international trade, the demand and export amount of Korean pine seed products are also increased year by year, the market demand is increased day by day, the price is greatly increased, a natural and organic emerging industry integrating the fields of healthy food, health care products, medicines and the like is formed by taking the deep processing of Korean pine seeds as a core, the development of Korean pine seed industry has wide development space and good development prospect, and the development of Korean pine seed industry has great economic potential. Therefore, enthusiasm for cultivating clonal fruit forest of Korean pine is increased in various places in the northeast, and development momentum of Korean pine grafted seedlings is high. Along with the continuous increase of the grafting workload, the use problem of the grafting cutter is also highlighted. Many nursery stock operators breed large batches of Korean pine grafted nursery stocks under the condition that grafting cutters are inconvenient to use and have certain danger degree, and the problems of large scion loss, uneven bred nursery stocks, low production efficiency and the like are caused.

A pith cambium grafting method is mostly adopted for building a clonal fruit forest of the Korean pine, and the problems of low survival rate and small growth amount of other methods used in the Korean pine grafting can be solved. A sharp blade is required to complete the cutting step during the manufacturing process. In the operation process of workers, the common blades are not smooth, so that scions are not cut in place and wasted, and the production efficiency is influenced occasionally. The flexible double-edge razor blade is smooth and has hand feeling, can be quickly cut into the scion medulla part and smoothly cut along the medulla part at one time, has very high smoothness and can greatly improve the working efficiency. The blade is comfortable and has good flexibility, and a novice can find hand feeling in a short time and adapt quickly. While other types of blades are too stiff to be so handy. However, such a double-edged razor blade needs to be separated into two parts from the middle, and in order to prevent frequent hand injuries, it is necessary to wrap an adhesive tape on one side of the half blade for easy handling. The area that half blade can be held is very little, hurts the hand easily, and it is also inconvenient not to use. The workload is large, the blade is required to be kept sharp, the blade is consumed at a high speed, the replacement speed is high, and the process of frequently winding the adhesive tape is time-consuming.

Disclosure of Invention

The utility model discloses the technical problem that will solve is: aiming at the problems, the grafting cutter is convenient to use, high in operation efficiency, easy to use, safe and reliable.

The technical solution of the utility model is that: the utility model provides a conifer kind grafting cutter, includes blade and handle of a knife, the blade is cut into two from the middle by twolip razor blade and forms, the position that one side of handle of a knife is close to the tip is equipped with the recessed groove that suits with blade tip shape, is equipped with the gland of being made by the platelike body on the handle of a knife, is equipped with "U" shape groove of fretwork on the gland, and the part that "U" shape groove wraps up constitutes according to the splenium, and the gland can connect on the handle of a knife vertically slidably, and some of blade inlays in the recessed groove, and other parts stretch out by the tip of handle of a knife, and the part in blade recessed groove can be covered to the slip gland, presses according to splenium and can exert pressure to the blade and press it firmly to press tightly on the handle of a knife.

The technical effects of the utility model are that: has the advantages of reasonable structural design, low cost, simple operation, convenient use, high production efficiency and small danger coefficient. The cutter has wide application range, can be applied and popularized in the fields of grafting technology and the like, is more suitable for the production of Korean pine grafted seedlings, and is more beneficial to the grafting of conifer species. Aiming at the defects of a cutter used in the existing Korean pine grafting process, the traditional knife adopting the medullary heart forming layer attaching method is improved, and a blade is embedded on a knife handle and can be quickly replaced. The grafting efficiency is improved, the loss of the scions is reduced, the production efficiency of grafted seedlings is utilized to the maximum, the scion cost is saved, the grafting survival rate is improved, and the hand injury of workers is reduced.

Detailed Description

As shown in fig. 1 to 4, a conifer species grafting cutter comprises a blade 1 and a handle 2, wherein the blade 1 is formed by cutting a double-edge razor blade into two parts from the middle, a blade embedding groove 3 which is adaptive to the shape of the end part of the blade 1 is arranged at the position, close to the end part, of one side of the handle 2, the depth of the blade embedding groove 3 corresponds to the thickness of the blade 1, a gland 4 made of a sheet body is arranged on the handle 2, a hollowed-out 'U' -shaped groove 5 is arranged on the gland 4, a pressing part 6 is formed by the part surrounded by the 'U' -shaped groove 5, the gland 4 is longitudinally connected to the handle 2 in a sliding manner, one part of the blade 1 is embedded in the blade embedding groove 3, the other part of the blade 1 is extended from the end part of the handle 2, the sliding gland 4 can cover the part of the blade 1 embedded in the blade embedding groove 3, and the pressing part 6 can firmly press the blade 1 on the handle 2.

The inner side surface of the pressing part 6 is provided with a flexible rubber patch 7. The rubber material can increase the friction force, and can also make the atress disperse to the contact surface through the mode of deformation, makes blade 1 more firm, uses more smoothly.

The inner side surface of the pressing part 6 is provided with a groove 8 convenient for pressing of a thumb.

The edge of two sides of the gland 4 is provided with a chute 9 formed by turned edges, and the gland 4 is connected to the knife handle in a sliding way by matching the chute 9 with the edge of the knife handle 2.

And the edges of two sides of the knife handle 2 are provided with slideways 10 matched with the sliding grooves 9 of the gland 4.

The handle 2 is provided with a limiting part 11 for preventing the gland from slipping at one end provided with the embedded groove 3.

The cutter device is designed aiming at needle-leaved trees, is used for producing grafting seedlings in nursery lands and improving and cultivating Korean pine clone fruit forest in mountain forestation lands, has wide application range, greatly improves grafting production efficiency, fully saves expense of Korean pine grafting scions, saves production cost and improves safety guarantee of workers.

When the cutter is used, the cutter blade is divided into two parts from the middle, then a half cutter blade is taken and placed in the cutter embedding groove, and the pressing cover is pushed forwards to cover the cutter blade part in the cutter groove. When the kitchen knife works, the knife handle part is held, the food finger is supported on the back of the knife handle, and the mother finger presses the pressing part of the pressing cover to apply certain pressure to the blade. Because the knife handle has more suitable thickness than the knife handle directly winding the rubberized fabric on the blade, the use is more convenient and free.
