Description

  The present invention realizes another new object by utilizing an incision and cutting action with a scissors.

  Plant growth in temperate and fertile areas is really strong. Regardless of whether it is a yard or a vacant lot around a house, many kinds of trees and plants sprout. Perhaps it is the germination of seeds that have been eaten and carried by birds and seeds that have fallen from surrounding trees or have been carried by the wind.

Without knowing, they sprouting secretly in parks, garden corners, shrub stocks, hedges, and street planting. Usually these weeds and weeds do not stop in our eyes unless they are of a certain size. When I noticed, the roots are quite deep, and when I try to pull it out, it is surprisingly strong, and the tree diameter is still thin, so it can be cut from the middle of the trunk before the root is pulled out, or only the bark is peeled off Become. In the next year, new shoots and leaves are grown from the roots.
The same is true for kuzu and so on, while the vines are growing in the weeds. When the leaves become noticeable in the surrounding weeds, the stems are usually quite thick and the roots are deep.

  In such cases, it is normal to dig from the root with a scoop, but this is not possible in an important garden, planting, fence, or shrub group. Also, if the roots are deep or wide, digging up can be a daunting task.

  Therefore, as another method, it is also possible to apply a foliage-type bactericidal agent having osmotic transfer properties to fresh cuts of stems, branches and trunks to withstand. The solution of glyphosate ammonium salt migrates through the plant body and inhibits the action of an enzyme called EPSPS necessary for producing an aromatic amino acid necessary for the growth of the plant to wither the plant. By the way, in the case of miscellaneous shrubs with a tree diameter of 50 mm or less, between March and October, 1 to 2 milliliters of a 41 percent solution may be injected into the core that is deeper than the vascular bundle.

  However, this method is complicated. While moving for work, you must always carry knives, scissors, containers with treatment solution, brushes, etc., place the container and damage the trunk with the knife, etc. Open and apply the treatment solution to the cut surface with a brush. The problem is that it is very cumbersome and inefficient. The work of climbing higher is even more so.

Although a kite for applying chemicals has been proposed, a tube for supplying chemicals is connected to the side of the blade that should be cut, a long tube is required, or a position that is always higher than the working height In reality, it is necessary to hold the chemical tank, and it is impossible to use it.
In addition, a method of digging a groove on the back surface of the cutting blade and applying a chemical to the cut surface has also been proposed, but this does not know where the chemical has gone, and it should be applied evenly and thoroughly to the cut surface. I can't.
Japanese Utility Model Sho 56-153160

Furthermore, when the diameter of the plant to be treated is small, the cross-sectional area may be too small to apply the required amount.
In addition, depending on the tree species, the treatment agent may be diluted with the sap that comes out from the cut end, and the effect may be weakened.
Furthermore, since it takes time to penetrate the applied treatment agent into the plant body, it should be left on the cut surface for about 1 day if possible, and at least 3 to 6 hours. It will be washed away and will not be effective.
Therefore, it is necessary to apply a processing agent with high stickiness and viscosity, but there is no way to handle such a processing agent.
ACT 02-73936 Hei Kaihei 03-31830

  So, without worrying about the weather too much, you can easily and reliably secure garden trees, weeds, etc. that you found unnecessary by caring for gardens and parks, etc. We propose a method for killing it and its traps.

First, it is desirable to increase the viscosity of the treatment agent in order to increase the sticking property and to be thickly applied to the cut surface. Alternatively, it is also one method to use after processing into a colloidal or gel form.
Moreover, it is necessary to apply | coat a processing agent to a cut surface reliably. Therefore, it is desirable to push the treatment agent so as to penetrate into the deep part of the plant tissue on the cut surface as much as possible.

  As shown in FIG. 1, a normal pruning shear has a cutting blade 1 and a receiving blade 2 facing each other. The receiving blade 2 is used on the tip side of the object 6 such as a branch, and the cutting blade 1 is used on the root side. The receiving blade 2 mainly receives the branch to be cut from below, and the cutting blade 1 is cut into the branch held by the receiving blade 2 from above. The cutting blade 1 enters the workpiece 6 by the action of gripping at the handgrip part using the blade fulcrum pin 5 as a fulcrum.

In view of this, a hole, that is, a path 7 is provided in the cutting blade constituent member from the handle as shown in FIG. 3 or from the portion of the blade to the side surface of the cutting blade.
And it proposes supplying a processing agent etc. under pressure. It can also be proposed to hold the container containing the treatment agent on the belt or the like of the worker and pump the treatment agent or the like from the container to the heel in the palm by a fixed length tube or the like. The work can be performed without any inconvenience since it is connected to the part of the handle in the palm.

By supplying a treatment agent such as a viscous material from the supply port E while cutting, useful treatment agents and the like are cut from the discharge port H on the side and front side of the cutting blade 1 as shown in FIGS. The treatment agent can be directly applied to the cut surface of the workpiece 6 by being discharged toward the surface or the like.
As shown in FIG. 4, the processing agent 8 is supplied between the cutting surface P of the workpiece 6 and the cutting blade side surface of the cutting blade 1, so that the cutting blade 1 adheres the inside of the workpiece 6 to the cutting surface P. While the cutting is proceeding, the processing agent or the like 8 is reliably rubbed against the cutting surface P simultaneously by the cutting blade side surface of the cutting blade 1.

  The position of the discharge port H at the end of the path is provided at a position close to the blade line in the middle of the blade.

  Next, as shown in FIG. 1, a recess is provided in the place of the radial end discharge outlet H on the side surface of the cutting edge to form a liquid reservoir 9. There is an advantage that a necessary amount of the processing agent or the like can be fed and stored here and applied to the cut surface sufficiently and widely.

In addition, it is proposed that the side surface of the cutting edge or the bottom surface S of the liquid reservoir 9 is provided with a groove, or that the cross-sectional shape is corrugated as shown in FIG. Since the cutting blade 1 enters into the workpiece 6 as indicated by the arrows in the figure, the cutting surface P of the workpiece 6 tends to hold down the side surface of the cutting blade and the bottom surface S of the liquid reservoir 9. Therefore, if the cutting blade side surface and the bottom surface of the liquid reservoir 9 are made uneven, as a result, the treatment agent 8 and the like 8 can be reliably rubbed against the cutting surface P.

  Furthermore, it is proposed that a pump using reciprocating motion such as a piston is attached to the handshake part, and the reciprocating motion that pushes and pulls the piston is directly linked to the gripping and returning motion of the handshake part of the heel.

  The processing agent 8 sent to the liquid reservoir 9 under pressure by a pump or the like has an internal pressure when the cutting blade side surface and the cutting surface P are in close contact with each other. While being pressed down to the deep part of the P structure, the extruded treatment agent 8 or the like is widely diffused between the side surface of the blade and the cutting surface P, and has an effect of expanding the coating area. These are remarkable because the higher the viscosity of the treatment agent, the easier the internal pressure is generated.

  It is possible to simultaneously apply a useful substance such as a treatment agent while cutting, incising or cutting with only the scissors of the present invention, thereby improving the efficiency of the entire operation. Further, since the bag of the present invention has good portability, there are further advantages in working in high places and narrow places.

  Furthermore, liquids and jelly-like, purine-like, wax-like, ointment-like fluids and semi-solids can be spouted into a fresh cut as they are fresh, and then directly pressed into the cut tissue or thickly applied. It becomes possible to make the medicinal effect stable and sufficient.

  Moreover, since the path leads to just below the cut surface, the sent processing agent is reliably applied to the cut surface.

Furthermore, since a series of operation and action are coupled mechanically, and all actions are performed with good timing in one operation, it is not necessary to concentrate much attention. When gripping is started, cutting starts at the small blade portion, and when the cutting is slightly advanced, a certain amount of processing agent is sent and the side surface of the cutting blade rubs it against the cutting surface. When gripping is completed, cutting or the like is completed, and a predetermined amount of application is completed on the cut surface, and the operation is completed.

As an example of this proposal, a general pruning shears for a right-handed person will be described as an example. Usually hold the heel in the right hand and hold the tip side of the branch to be cut with the left hand slightly. When it is pressed firmly, the cut opens quickly. Normally, the receiving blade is on the left side with respect to the cutting edge, that is, the branch side to be cut.
Hereinafter, the present invention will be described more specifically with reference to examples.

First, a heel that operates a pump between two handles of the heel, that is, a thumb handle and a four finger handle is proposed.
As shown in FIG.
(A) A piston-type pump device 11 is attached to the handle portion of one blade (K) so that the axial center line of the piston 12 is in a tangential direction on an arc centering on the blade fulcrum pin 5.
(B) The piston 12 and the handle portion of the other blade (U) are connected by a connecting rod 15 having hinge structures at both ends.
(C) The discharge port (G) of the pump device 11 and the path 7 are connected.
Constructed as described above, the gripping and returning motion of the handshake part is converted into the reciprocating motion of the piston, the pump device 11 is interlocked, and the processing agent 8 is pumped to the side of the cutting blade in a timely manner by cutting with the pump. Propose a kite that can be used.

  The repeated operation of gripping and returning as a scissors performed at the handshake part, that is, the motion of the handshake part that opens and closes in a fan shape with the blade fulcrum pin 5 as the center point can be converted into 100% of the reciprocating motion of the piston 12. The processing agent 8 is drawn into the cylinder 13 in the stroke return stroke, the processing agent 8 is fed out in the stroke stroke, and a fixed amount of the processing agent 8 is cut through the path 7 provided inside the cutting blade component. It sends to the liquid pool 9 on the front side of the blade.

  In the case of a treatment agent having poor fluidity such as a viscous material, it is necessary to send it with a large pressure. However, if the path 7, piston 12, cylinder 13, etc. are made of a robust material such as metal or plastic, this can be achieved.

In general, we cut tree branches, weeds, etc. with pruning shears, which is generally less than 20 mm in diameter. Although there are differences depending on the design of the heel pattern and the palm of the user, it is often cut with a small blade about 20 to 35 mm away from the center of the blade fulcrum. Therefore, a liquid reservoir 9 is provided in the vicinity according to the purpose of the bag. As shown in FIG. 4, when the liquid reservoir 9 portion of the cutting blade 1 penetrates into the workpiece 6, it will be in a sealed state unless the left hand is pressed down strongly to open the cut. Since the treatment agent 8 is in a state where an internal pressure is applied by the action of the pump, the treatment agent 8 is pressed against the cut surface P with an equal pressure and is pushed to the deep part of the tissue of the cut surface P.

In addition, the supply of processing agents, etc. by the pump, pressurization and cutting action as scissors and pressing and rubbing action on the cut surface are linked in one operation, so that each action is timely and stable application There is also an effect that is surely performed. Also, if the handle is closed, the supply from the pump device stops and the amount supplied from the pump device with a single grip is constant, making it easy to grasp and manage the application amount.

  When a thin branch has to be cut, or in preparation for use in which the cutting situation cannot be visually recognized by one's own eyes, as shown in the example of FIG. It is preferable to attach a mark 10 indicating the position.

Further, it is more convenient if the container 16 containing the processing agent 8 is made small and attached to the handshake part so that it can be used even when climbing a high place.
Further, a case 17 for storing the container is provided so as to be fixed to the handshake part, and the bottom of the shrinkable container 16 stored in the case 17 is pushed by a container spring 18 or the like, so that the container 16 is compressed while being compressed. When the processing agent 8 is naturally supplied to the pump device 11, the processing agent 8 is smoothly and stably sent out from the pump device 11.

  There is a valve or cock that can stop the supply of processing agent etc. in front of the pump device, and the connection between the piston and the handle is disconnected between the operation of the pump and the operation of the connection between the piston and the handle. If a mechanism is provided, it becomes possible to perform a single pruning operation with the pruning shears of the present invention as required in the work, which is more convenient.

Next, an example of a pruning shears that applies a preservative, a desiccant, or other treatment agent to the cut branches and the like will be described.

The arrangement of the pump and the related operation action are the same as those in the first embodiment, except that the processing agent and the like pumped by the pump are discharged from the side surface of the cutting blade back side of the cutting blade 1 as shown in FIG. Since the treatment agent or the like is discharged from the liquid pool 9 on the back side of the cutting blade, it can be applied to the cut surface of the branch to be cut off.

In this case, since the back surface of the cutting edge of the cutting blade 1 is generally flat, a gap is hardly generated between the cutting surface and the liquid pool, and the internal pressure generated in the treatment agent can be made higher than that in the first embodiment. There is a tendency for application to be reliable.

The same effect can be expected by once cutting with a scissors as usual, and then rubbing the cut surface of a manually cut branch or a remaining branch against the liquid reservoir 9. Further, by using the side surface on the side where the liquid reservoir 9 is used as a ridge, a treatment agent or the like can be applied to various cut surfaces.

  Combining the pruning shears of the present invention with a herbicide of the foliage treatment type can be used for selective killing of deciduous shrubs, some evergreen shrubs, is portable and efficient, Contributes to reliable processing.

Not only can it be used for landscape work on trees and plants in gardens, parks, streets, but it can also be used for thinning trees such as Japanese cedar and cypress. When the tree has a small tree diameter, take a large cut surface by diagonal cutting. When the tree diameter is too large, the treatment agent can be injected into the outer periphery of the tree trunk by cutting it while turning it.

It can also be used in the same manner when weeds with relatively thick weeds such as Japanese pampas grass and stag beetle.
It is difficult to eliminate kuzu in the weeds, but if it is a commercially available 41-percent glyphosate ammonium salt treatment agent, it can be killed with the above-mentioned medicinal properties if it is applied to 1 to 2 milliliters per strain. I can do it. If the concentration is increased, a smaller amount can be used.

Application methods include preventing fruit trees such as peaches, pears, apples and persimmons, or garden trees such as maple trees, and roadside trees, and insects such as beetles and caterpillars from entering the trunk, leaves, pulp, new treetops, and under the tree. In order to prevent or control, a method of penetrating an insect repellent, insecticide, etc. having penetrability from the cut surface of the branch of the present invention can also be proposed. It is also effective for extermination and prevention of insect pests such as scale insects, leafhoppers, beetles, aphids, whiteflies, thrips, etc. that have arrived on the bark, leaves, or entered the trunk.
Furthermore, it is possible to propose combinations of seeds such as strawberries and strawberries with no seeds, fruit enlargement, and ripening promoting agents.
In addition, wax can be applied to prevent germs from entering from the cut end.

  In addition, as a treatment for the branch on the side to be cut off, a combination with antiseptics, desiccants, nutrients, etc. can be conceived for harvesting grafting spikes, collecting florets and the like. Since the side surface on the back side of the cutting edge is generally planar, a bactericidal agent and a moisturizing agent can be applied to the cut end without roughening the cut end when collecting scion or flower buds.

  The application of the present invention is not limited to pruning shears. It can also be applied to general rice cakes that are cut with repeated gripping and returning, gardening rice cakes, bonsai rice cakes, gardening rice cakes, etc. The effect is the same as that of the pruning shears described above. It is also possible to propose reversing the positional relationship between the cutting blade and the receiving blade in the pruning shears. If you want to press abactericide, etc. strongly against the root cross-section of the root side, cut the root and back from the side of the side of the cutting edge that has a flat shape with the cutting blade and receiving blade in the opposite positional relationship of the normal scissors It is good to spit on the surface.
