Description

Bark over-cutting prevention device for camellia oleifera tree grafting seedling

Technical Field

The invention relates to the technical field of oil-tea tree grafting, in particular to a bark over-cutting prevention device for oil-tea tree grafting seedling.

Background

The camellia oleifera is a famous Chinese snack in Sichuan Yu region and belongs to a Sichuan dish. As breakfast, rice paste, mulberry kernel, crisp soybean or peanut, chopped radish, salt, pepper powder, chili oil, monosodium glutamate, shallot, even food, and northern camellia oil are different, spicy and delicious. The conventional rice paste is prepared by grinding rice flour to obtain ordinary rice, adding water, and cooking to obtain rice paste with proper thickness.

The camellia oleifera is easy to sow and breed. Can be directly planted with good effect. The oil tea can be obtained within three years. Because the camellia oleifera has drought resistance and cold resistance, the grafted camellia oleifera has strong stress resistance. Grafting is a method for artificial propagation of plants. That is, the shoot or bud of one plant is grafted onto the stem or root of another plant, such that the two parts are joined together to form a complete plant. The grafting method is divided into branch grafting and bud grafting. Grafting is the function of utilizing the wounded callus of plant. Before the bark or the branch of the oil-tea camellia tree is manually used for grafting, the special cutting and cutting equipment is required to be used for cutting the bark or the branch in a fixed length mode so as to facilitate the normal operation of the next grafting step, but because the branch or the bark is generally hard in texture, the cutter can cause over-cutting due to inertia, on one hand, the cutting equipment can be damaged, and on the other hand, the bark can be cut and damaged to influence the grafting.

Wherein: the surface of the limiting block 8 is provided with a through hole, the diameter of the through hole is matched with the cutting knife 5, and the cutting knife 5 penetrates through the through hole from top to bottom. The stop block 8 will limit the movement of the cutting knife 5 in the vertical direction only.

Wherein: the bottom end of the return spring 4 is fixedly connected to the side end surface of the base 1.

Wherein: the contact 19 is specifically composed of two balls and a spring which are attached to each other, two ends of the spring are respectively and fixedly connected to the balls and the inside of the base 1, and the contact 19, the current transformer 18 and the electromagnet 12 are electrically connected to each other.

Wherein: the main components of the electrorheological fluid 18 are gypsum, lime, carbon powder, olive oil, and water. When the electrorheological fluid 18 is energized, its texture will harden.

Wherein: the fixed stop blocks 14 and the movable stop blocks 17 are respectively provided with six and four and are uniformly distributed by taking the shaft center 9 as the center of a circle. The number of fixed stops 14 and movable stops 17 are not matched to each other and at least two of the movable stops 17 are in different states to simultaneously buffer the volume flow change of the electrorheological body 18.

Wherein: the ground of base 1 is fixedly connected with the support, and its top is through the mutual swivelling joint between fixed connection's axle center 9 and handle 7.

Wherein: the inner ring surface of the inner shaft 13 is fixedly connected with a ratchet wheel which is matched with the clamping hook 10.

The working principle is as follows: compare fig. 1 and fig. 2, the grafting bark that will wait to cut is placed and is located cutting knife 5 on base 1 surface under the position, operation handle 7, make it around with the support tie point as fig. 1 clockwise rotation, the top of handle 7 drives swivelling joint's transfer line one 2 and transfer line two 3 synchronous revolution through transfer line three 6 this moment, wherein transfer line one 2 is rotatory around the tie point with base 1, simultaneously tensile reset spring 4, and cutting knife 5 is because the whole horizontal position of transfer line two 3 descends, thereby drive cutting knife 5 and cut the bark downwards under the limiting action of stopper 8, after the cutting is accomplished, loosen handle 7, all structures can reset through reset spring 4's shrink. So far, all the operations of cutting the grafting bark of the oil tea tree are completed, and the purpose of convenient operation is realized.

In the cutting process, because the bark has certain hardness and toughness, when the dynamics of operating handle 7 is too big, the bark may break off in the twinkling of an eye, and cutting knife 5 descends rapidly, after meetting the ball of contact 19, will squeeze the ball to both ends, compresses the spring simultaneously, and the ball is because not hugging closely at this moment, and the contact 19 signal of telecommunication disconnection to will cut off the power off signal transmission to current variant 18 and electro-magnet 12 department. Normally, the electrorheological fluid 18 is soft, the movable stop 17 is contacted with the fixed stop 14 of the inner shaft 13 in the process of rotating and driving the outer shaft 15, at this time, the stop is compressed, the two stops cannot block the relative rotation between the inner shaft 15 and the outer shaft 15, and after the electrorheological fluid 18 becomes hard, the shape of the electrorheological fluid is fixed, the stop spring 16 is clamped to enable the electrorheological fluid not to normally contract, and at this time, the two stops can block the relative rotation between the inner shaft 15 and the outer shaft 15. In addition, although when normally rotating, the movable stopper 17 can extrude the current transformer 18 inwards, but because the quantity of the fixed stopper 14 and the movable stopper 17 is even number respectively and is not matched with each other, the movable stopper 17 has two groups of stoppers with the same quantity which are in different compression states respectively, on one hand, the stability of the structure can be improved, on the other hand, the whole volume of the current transformer 18 is ensured to be unchanged, and the current transformer is prevented from being incapable of normally flowing due to volume reduction.

When the electric signal of the contact 19 is not transmitted to the position of the electromagnet 12, the electromagnet 12 is electrified, and the attraction hook 10 is positioned in the axle center 9, and the clamping spring 11 is compressed, so that the relative rotation of the axle center 9 and the inner shaft 13 is not hindered. When the electromagnet 12 is powered off, the clamping spring 11 extends, the clamping hook 10 extends, the ratchet wheel fixedly connected with the inner part of the clamping inner shaft 13 limits the handle 7 to continue rotating clockwise, the cutting knife 5 is prevented from further moving downwards, the handle 7 is loosened, and the clamping hook 10 cannot be used for limited manufacturing, so that the normal resetting of the clamping hook can be ensured.

The invention adopts the design of triaxial double-layer relative rotation to replace the common mode of biaxial single-layer relative rotation, and can further improve the stability and fault-tolerant rate of the structure operation on the premise of normally realizing the purpose of the invention, so that the invention has wider applicability and higher practical value compared with the prior structure.

Although embodiments of the present invention have been shown and described, it will be appreciated by those skilled in the art that changes, modifications, substitutions and alterations can be made in these embodiments without departing from the principles and spirit of the invention, the scope of which is defined in the appended claims and their equivalents.
