Description

  The present invention relates to a multi-seat laying support tool for easily and surely laying a so-called agricultural multi-seat on a vine in a field and making a worker's working posture easy.

In general, in field work, in order to cope with a cold time such as winter, after crops are planted at intervals in field fences, agricultural multi-sheets are laid on the fences to protect the crops from cold. Furthermore, after that, through the germination, seedling growth, etc., agricultural work such as forming an opening in the agricultural multi-sheet is required.
Agricultural multi-sheet is a sheet made of a thin plastic film, and is intended to keep the ground temperature, prevent weed germination and growth, and prevent fertilizer outflow in order to promote the growth of crops. In addition, in order to prevent the growth and growth of weeds, a black color that shields light is often used.

  Laying agricultural multi-sheets is generally not easy and requires a knack. For example, when an agricultural multi-sheet wound in a roll shape is laid while rolling on a ridge, the roll-shaped agricultural multi-sheet is likely to meander, making it difficult to lay alone. In addition, the width of the ridge is determined according to the crop to be planted, and it is necessary to plant according to the appropriate planting interval (between stocks and streaks) according to the crop to be planted. It was difficult to handle. This is especially difficult for beginners.

Thus, in the prior art, several devices that support the laying of agricultural multi-sheets have been proposed.
For example, the technique of Unexamined-Japanese-Patent No. 2003-180174 is known (patent document 1). The technology disclosed in Japanese Patent Application Laid-Open No. 2003-180174 includes a rod-shaped body that is inserted into a hole of a roll core of a roll-shaped agricultural multi-sheet and a string for guiding that is detachably attached to both ends of the rod-shaped body. It is. Agricultural multi-sheets are wound around a winding core in a roll shape, and the technique disclosed in Japanese Patent Application Laid-Open No. 2003-180174 inserts a rod-shaped body such as wood into the winding core and attaches a string-shaped body to both ends thereof. In use, by pulling the middle of the string-like body, the rod-like body is drawn perpendicularly to the heel, and as the rod-like body advances, the rod-like body is inserted into the roll core and the roll core. As the rolled multi-seat rotates, the multi-seat is unwound and laid.

  Further, for example, a technique disclosed in Japanese Utility Model Publication No. 58-107774 is known (Patent Document 2). The technique of Japanese Utility Model Publication No. 58-107774 is similar to Patent Document 1 in that it has a rod-like body that is inserted into the hole of the core of a roll-shaped agricultural multi-sheet, but is not a string-like body. It is provided with a wooden frame for guidance that is fixed to both ends of the frame. That is, it has a wooden frame instead of a string. In use, pulling the handle of the wooden frame, the rod-shaped body is drawn around perpendicularly to the heel, and the roll core is inserted into the winding core through which the rod-shaped body is inserted as the rod-shaped body advances. The multi-seat wound around is rotated and the multi-seat is unwound and laid.

JP 2003-180174 A Japanese Utility Model Publication No. 58-107774

However, the conventional multi-sheet laying support tool has the following problems.
First, the first problem of the multi-sheet laying support tool disclosed in Japanese Patent Application Laid-Open No. 2003-180174 is that the length of the rod-shaped body is determined, and thus the width of the agricultural multi-sheet to be attached is limited. It is a problem. As described above in the section of the prior art, the width of the multi-sheet is determined according to the width of the ridge suitable for the crop to be planted, and various widths are sold, and the worker selects the multi-sheet according to the crop. However, in the multi-sheet laying support tool disclosed in Japanese Patent Laid-Open No. 2003-180174, the width of the agricultural multi-sheet to be attached is limited. Japanese Patent Application Laid-Open No. 2003-180174 discloses a means for adjusting the width of a multi-sheet to be attached, in which a rod-shaped body is divided into a plurality of parts in the length direction and that which expands and contracts in the length direction by a charging structure. However, it is actually difficult to adjust the length of the rod-like body, and the width of the agricultural multi-sheet to be attached is practically limited.

  Further, the second problem of the multi-sheet laying support tool disclosed in Japanese Patent Laid-Open No. 2003-180174 is that the string-like body and the rod-like body are unexpectedly detached during use, and as a result, the roll-shaped multi-sheet is detached from the entire core. It is a problem that this problem is likely to occur. A string-like string connector is pushed in and attached to both ends of the rod-shaped body, but if a multi-sheet is laid by rolling on a non-uniform ridge, vibrations are transmitted, and both ends of the rod-shaped body It becomes easy to generate | occur | produce the malfunction that a string coupling tool will remove | deviate from a roll and a roll-shaped multi-sheet will also remove | deviate.

  Next, the multi-sheet laying support tool disclosed in Japanese Utility Model Publication No. 58-107774 also has a problem that the width of the agricultural multi-sheet to be attached is fixed because the width of the wooden frame is fixed. As described above in the section of the prior art, the width of the multi-sheet is determined according to the width of the ridge suitable for the crop to be planted, and various widths are sold, and the worker selects the multi-sheet according to the crop. However, in the multi-sheet laying support tool disclosed in Japanese Utility Model Publication No. 58-107774, the width of the agricultural multi-sheet to be attached is fixed. There was a problem that a multi-seat laying support tool had to be purchased and prepared.

  The present invention has been devised in view of the above-described conventional problems, and can be attached corresponding to agricultural multi-sheets of various widths with a simple structure and a small number of steps, making the agricultural work of multi-sheet laying easy. An object of the present invention is to provide a multi-sheet laying support tool that can be used.

The multi-sheet laying support tool of the present invention includes a first connecting tool that includes an outer surface body larger than the hole diameter of the core of the agricultural multi-sheet and an inner surface body smaller than the hole diameter of the core, and is attached to the hole at one end of the core. And a second connector attached to the hole at the other end of the winding core, a first string member having one end connected to the outer surface of the first connector, and one end connected to the inner surface of the first connector. The other end passes through the inside of the core and passes through the outer surface body from the inner surface body of the second connector, and the second string body is slidably mounted on the second string body. In the state, it has a restraining body that is stationary on the second string body due to frictional force and restricts the movement of the second coupling tool, and the second coupling tool is movable on the second string body. Agricultural machinery in which the second connector is restrained according to the position on the second string body, and the distance between the first connector and the second connector is adjusted. Is a Chishito laying assistance instrument.
By the said structure, the distance between a 1st coupling tool and a 2nd coupling tool can be adjusted freely, and it can respond even if it is an agricultural multi-sheet of what width. Moreover, since the 2nd string body is attached in the form which penetrates in the core material of an agricultural multi-sheet, the malfunction that an agricultural multi-sheet will remove | deviate unexpectedly does not generate | occur | produce.

  As a method for attaching the agricultural multi-sheet, the second string member is inserted through the hole at one end of the core and pulled out from the other end, and the inner surface of the first connector is stored in the hole at one end of the core. Attach, let the other end of the second string pass through from the inner surface of the second connector to the outer surface, and insert the second connector along the second string into the hole at the other end of the winding core The restraining body may be inserted from the other end of the second string body, and the restraining body may be slid along the second string body and attached to the position where the second connector is restrained.

  In addition, in the said structure, the structure which makes a part of 2nd string body an elastic body in the range of the inner surface body of a 1st coupling tool to the inner surface body of a 2nd coupling tool is preferable. The elastic body is not particularly limited, and examples thereof include a spring and rubber.

  In the above configuration, after the second connector is attached to the hole at the other end of the core, the second connector is further stretched to generate the elastic force and the second connector is attached to the stopper. By stopping at the stopping position, the elastic body pulls the first connector and the second connector from the inside of the core, and the first connector and the second connector pull the core from both sides. It becomes the structure clamped firmly, and it becomes difficult for a 1st connection tool and a 2nd connection tool to fall out from a core.

  Note that, in the above configuration, the first connector and the second connector have a structure that can rotate between the outer surface body and the inner surface body so that the agricultural multi-sheet can be easily rotated, and the core is easily rotated. A structure is preferable. The rotating means is not particularly limited. For example, there is a structure in which a bearing mechanism is provided on the boundary surface between the first connector and the second connector.

  Moreover, it is preferable to attach the line used as a scale or the color classification used as a scale on the 2nd string body. By attaching such scales and color coding, it can be used as a guide for adjusting the width at the time of attachment with respect to various widths of the agricultural multi-sheet.

According to the multi-sheet laying support tool of the present invention, the distance between the first connector and the second connector can be freely adjusted, and any width multi-seat farm can be used. Can do. Moreover, since the 2nd string body is attached in the form which penetrates in the core material of an agricultural multi-sheet, the malfunction that an agricultural multi-sheet will remove | deviate unexpectedly does not generate | occur | produce.
According to the multi-sheet laying support tool of the present invention, a part of the second string body is an elastic body in the range from the inner surface body of the first connector to the inner surface body of the second connector. For example, the elastic body pulls the first connector and the second connector from the inside of the core, and the first connector and the second connector can firmly hold the core from both sides. It becomes difficult for the first connector and the second connector to come off from the core.

  Hereinafter, embodiments of a multi-sheet laying support tool of the present invention will be described with reference to the drawings. However, the technical scope of the present invention is not limited to the specific applications, shapes, dimensions, and the like shown in the following embodiments.

  As a first embodiment, a first configuration example of the multi-sheet laying support tool 100 of the present invention is shown. FIG. 1 is a diagram showing a configuration example of a multi-sheet laying support tool of the present invention.

  As shown in FIG. 1A, the multi-sheet laying support tool 100 includes a first connector 110, a second connector 120, a first string body 130, a second string body 140, an elastic body 141, The stop body 150 is provided. In addition, the structure of the agricultural multi-sheet 200 is demonstrated as what was provided with the multi-sheet material 210 and the core 220 (hole diameter R of a core), as shown in FIG.1 (b). Each part of the winding core 220 has one end 221, its hole 222, its other end 223, and its hole 224, as shown in FIGS.

  The first connector 110 includes an outer surface body 111 larger than the hole diameter R of the core 220 of the agricultural multi-sheet 200 and an inner surface body 112 smaller than the hole diameter R of the core 220. As shown in FIG. 2A, the inner surface body 112 is fitted into the hole 222 of the core 220, but the outer surface 111 abuts against the edge of the hole 222 of the core 220, and the first connector 110 is It is attached to one end 221 of the winding core 220.

In this configuration, as shown in FIG. 2 (b), the first connector 110 is structured to be rotatable between the outer surface body 111 and the inner surface body 112. For example, a bearing structure or the like is charged between the two, and the outer surface 111 and the inner surface 112 are easy to rotate. As long as the inner surface body 112 easily rotates when the outer surface body 111 of the first connector 110 is pulled through the first string body 130, the first string body 130 and the second string body 2 By pulling the string 140, the winding core 220 and the multi-sheet material 210 rotate smoothly with the progress of the user, and the multi-sheet laying operation becomes easy.
The second connector 120 may have the same configuration as the first connector 110 in this configuration example, and the description thereof is omitted here.

  As shown in FIG. 4, the first connector 110 is attached to the hole 222 of the one end 221 of the core 220 of the agricultural multi-sheet 200, and the second connector 120 is not only the core 220 of the agricultural multi-sheet 200. It is attached to the hole 224 of the end 223.

  The first string 130 may be a string having a certain degree of tensile strength, such as a fiber string, a vinyl string, or a wire. One end of the first string 130 is connected to the outer surface 111 of the first connector 110, and the other end is held by the user as one of the strings, and is pulled as described later.

  The second string 140 may be a string having a certain degree of tensile strength, such as a fiber string, a vinyl string, or a wire, like the first string 130. As shown in FIG. 1A, the second string 140 passes through the outer surface 121 from the inner surface 122 of the second connector 120, and as shown in FIG. The connector 120 can move freely along the second string 140. However, as shown in FIG. 4 which will be described later, when it is sandwiched between the restraining body 150 and the outer surface body 121 of the second connector 120, it does not slide.

  As shown in FIG. 4, one end of the second string 140 is connected to the inner surface 112 of the first connector 110, and the inner surface 122 of the second connector 120 passes through the inside of the winding core 220. Is pulled out through the outer body 121 and connected to the user's hand, and the user pulls it.

  In this configuration example, the second string 140 is partially provided with an elastic body 141. The elastic body is not particularly limited, such as a spring or rubber. The range in which the elastic body 141 is provided is a range from the inner surface body 112 of the first connector 110 to the inner surface body 122 of the second connector 120 as shown in FIG. When attached to 200, the range is located inside the core 220 of the agricultural multi-sheet 200, as shown in FIG.

  That is, in this configuration, as shown in FIG. 5, an elastic body 141 is provided between the first connector 110 and the second connector 120 attached to both ends of the winding core 220, and both ends are caused by the elastic force. The first connector 110 and the second connector 120 are firmly tightened so that the first connector 110 and the second connector 120 do not come out from both ends of the core 220.

  Moreover, the structure which attaches the line used as a scale and color classification in the 2nd string 140 is also possible. By providing a scale line and color coding, when the agricultural multi-sheet laying support tool 100 of the present invention is mounted on the agricultural multi-sheet 200, the distance between the first connector 110 and the second connector 120 can be adjusted. It can be used as a guide.

  Next, the restraining body 150 is slidably mounted on the second string body 140, and is stationary on the second string body 140 by a frictional force in a natural state. In this configuration example, as shown in FIG. 3A, the restraining body is a member having three holes, and the second string 140 is passed through the zigzag so as to sew these three holes. Install. As shown in FIG. 3B, a large frictional force is applied if both ends of the second string 140 are pulled, and the restraining body 150 does not move on the second string 140 in the natural state. On the other hand, as shown in FIG. 3C, the position of the restraining body 150 on the second string 140 is adjusted if the second string 140 is fed out into each hole of the restraining body 150. be able to. If the stop body 150 is arranged so as to abut on the second connector 120, the movement of the second connector 120 is restricted.

  As described above, the second connector 120 can be freely moved on the second string 140 at the time of the initial attachment setting, but the second connector 120 is attached to the other end 223 of the core 220. After being applied, the elastic body 141 always applies a pulling force to the core 220 side, and further, since there is a restraining body in a direction away from the core 220, it is near the hole at the other end on the core 220 side. It will be in a stable state.

  That is, in the agricultural multi-sheet laying support tool 100 of the present invention, the distance between the first connector 110 and the second connector 120 can be freely adjusted, and after the adjustment, it is in a stable state without being easily detached. Thereafter, the distance between the first connector 110 and the second connector 120 can be easily changed. That is, the width of the multi-sheet 210 can easily correspond to various ones.

Next, a method for attaching the agricultural multi-sheet laying support tool 100 of the present invention to the agricultural multi-sheet 200 will be described. As an example, the width of the agricultural multi-sheet 200 to be mounted is 2 m.
In the initial state, as shown in FIG. 6A, the agricultural multi-sheet laying support tool 100 of the present invention is only the first string body 130, the first connecting tool 110, the second string body 140, and the elastic body 141. Are connected, and the second connector 120 and the restraining body 150 are removed.

(Procedure 1)
The second string 140 and the elastic body 141 are dropped from the hole 222 at one end 221 of the core 220 of the agricultural multi-sheet 200, and the second string 140 is removed from the hole 224 at the other end 223 of the core 220. (FIG. 6B). If the second string body 140 is continuously pulled out as it is, the first connector 110 reaches the vicinity of the hole 222 of the one end 221 of the core 220. Since the diameter of the inner surface body 112 of the first connector 110 is smaller than the diameter R of the winding core 220, the inner surface body 112 is accommodated in the hole 222 of the winding core 220, and the diameter of the outer surface body 111 is larger than R. Stops at the edge of the hole 222 of the core 220, and the first connector 110 is attached to one end 221 of the core 220 (FIG. 7A).

(Procedure 2)
The tip end of the second string 140 that has come out from the other end 223 of the winding core 220 is inserted from the inner surface body 122 of the second connector 120 into the outer surface body 121 and is inserted toward the winding core 220. If the second connector 120 is slid as it is toward the core 220, the inner surface 122 of the second connector 120 has a diameter smaller than the diameter R of the core 220. Since the diameter of the outer surface body 121 is larger than R, the outer surface body 121 stops at the edge of the hole 224 of the core 220, and the second connector 120 is attached to the other end 223 of the core 220 (see FIG. 7 (b)).

(Procedure 3)
Here, the second string 140 is further drawn in the outer direction of the second connector 120 (the user's hand direction). Since a part of the second string body 140 located inside the winding core 220 is the elastic body 141, the elastic body 141 is stretched by drawing the second string body 140, and an elastic force is generated ( FIG. 7 (c)).

(Procedure 4)
In a state where the elastic force 141 is appropriately applied with the elastic force 141, the stop body 150 is adjusted to be positioned immediately after the second connector 120 (on the user's hand side), so that the second string body 140 is stopped. A large frictional force is generated through the body 150 so as to sew, and the movement stops. In this state, the relative position of the second string body 140 and the restraining body 150 is fixed, and the restraining body 150 and the second connector 120 abut (FIG. 8A).

  As described above, the first connector 110, the core 220, the second connector 120, and the restraining body 150 are shown in FIG. 8A due to the elastic force of the second string 140 and the elastic body 141. Fixed in state. The winding core 220 is sandwiched between the first connector 110 and the second connector 120.

  Next, the agricultural multi-sheet laying operation by the agricultural multi-sheet laying support tool 100 of the present invention will be briefly described.

(Usage procedure 1)
After mounting the agricultural multi-sheet 200 in the above procedure, the user is pulled out from the length of the first string 130 and the other end of the core 220 in an agricultural work site such as a basket as shown in FIG. The second string 140 is held at a position where the lengths of the second string 140 are substantially equal.

(Use procedure 2)
If the user moves along the reed as it is, the agricultural multi-sheet 200 becomes substantially perpendicular to the reed, and the multi-sheet material 210 wound in a roll is fed out along with the movement of the user. Go over.
At this time, as shown in FIG. 9, the first connector 110 and the second connector 120 are smoothly rotated by a mechanism such as a bearing mechanism, and the multi-sheet material 210 is fed out.

  If it is necessary for the user to stretch the multi-sheet material 210 having a different width with another scissors, the agricultural multi-sheet 200 from the agricultural multi-sheet laying support tool 100 according to the present invention is performed in a procedure reverse to the above-described mounting procedure. And another multi-agricultural sheet 200 having an appropriate width may be attached and used.

  While the preferred embodiments of the agricultural multi-sheet laying support tool of the present invention have been illustrated and described above, it will be understood that various modifications can be made without departing from the technical scope of the present invention. .

  The present invention can be widely applied to tools for laying agricultural multi-sheets. It is not limited to the width of agricultural multi-sheets and can handle various widths.
