Description

[0001]
BACKGROUND OF THE INVENTION
The present invention relates to a seed string cutting device that can be used in connection with a seed string seeding device or the like that seeds a vegetable or the like in a field or the like with a seed string, and cuts the seed string at the seeding end point.
[0002]
[Prior art]
Work to sow fields using seed tape that holds vegetable seeds etc. on a tape at regular intervals, or wrapping seeds in paper tape such as non-woven fabric and entangled with strings (hereinafter collectively referred to as seed strings in this application) Is widely practiced.
There has been practiced a sowing method in which a plurality of seed string seeding devices (in multiples) are towed with a trucker or the like and simultaneously laid on a large number of ridges. In such a case, it is necessary to cut the seed string at the seeding end point. Conventionally, a method has been employed in which an operator is out of the track and inserts a cutter into the soil and cuts it in the soil, or mechanically inserts a number of blades into the soil and cuts them.
[0003]
[Problems to be solved by the invention]
As described above, when the cutter is repeatedly inserted into the soil, the cutting edge is worn and dull, which is not preferable.
An object of the present invention is to provide a novel seed string cutting device that does not depend on a method for inserting a blade into soil.
[0004]
[Means for Solving the Problems]
In order to achieve the above object, a seed string cutting device according to the present invention comprises:
A seed string cutting device for cutting a seed string supplied and embedded in soil at a seeding end point,
Is composed of a means for contacting the cutter is provided on the soil pressing disposed it has been said in a plane intersecting the direction of the seed string seeds cord to hold scooping part of the seed string soil surface Yes.
The means for bringing the seed string into contact with the cutter may be a lever that has a hook at the tip in a plane intersecting the direction of the seed string, moves under the seed string, and scoops up part of the seed string. The cutter can be provided in the movement path of the lever.
[0005]
[Action]
According to the above configuration, the seed string that is supplied to the soil from the seed string reel and buried is driven by the lever and moved below the seed string by the hook at the tip of the lever, and the seed string is arranged in the space. It can be cut by pressing against the cutter.

DETAILED DESCRIPTION OF THE INVENTION
Hereinafter, the present invention will be described in more detail with reference to the drawings.
FIG. 1 is a schematic side view showing a state in which an embodiment of a seed string cutting device according to the present invention is used in combination with a seed string seeding device. 2 is a rear view of the seed string cutting device shown in FIG. 1, and is a view of the seed string seeding device shown in FIG. 1 as viewed from the rear side in the traveling direction. FIG. 3 is a schematic plan view showing the positional relationship of the seed string cutting device with respect to the seed string embedded in the seed string seeding device. FIG. 4 is a schematic plan view showing a state in which the seed string is cut by the seed string cutting device at the end of sowing when the seed string is embedded by the seed string seeding device.
[0007]
As shown in FIG. 1, a main frame 11 and a pressing roller lever 13 are rotatably provided on a main shaft 9 of the seed string seeding device by a connecting shaft 8.
A spring 19 is spanned between the main frame 11 and the main shaft 9, and a spring 18 is spanned between the main frame 11 and the pressing roller lever 13. A pressing roller 3 whose surface is an elastic member is rotatably provided at the distal end side of the pressing roller lever 13, and a guide ring 15 provided by processing a wire is provided at the distal end of the pressing roller lever 13. . A planting main roller 5 is rotatably provided on a shaft 22 provided on the main frame 11. The implanted main roller 5 is provided with a pair of flanges 7 and 7 and hubs 21 and 21. A flange 17 is provided in association with the main shaft 9, and when the main shaft 9 is moved in the direction of arrow B, the groove 17 a is formed by the flange 17. A seed string cutting device CU is provided on the rear end side of the main frame 11.
[0008]
The configuration of the seed string cutting device CU will be further described with reference to FIG. The frame 31 of the seed string cutting device CU is provided integrally with the main frame 11. In addition, it can also be provided separately behind the seed string sowing device. The frame 31 is provided with a guide shaft 32, and a lever 39 is coupled to the guide shaft 32 by a long groove 39a of the lever.
A bifurcated hook portion 39 b is provided on the lower end side of the lever 39. A spring 35 is provided between the pin at the upper end of the lever 39 and the frame 31, and the pin is coupled to the rope 36, and the rope 36 is formed by the rope guide 33 provided integrally with the frame 31. It is provided so that it can be pulled upward through a hole. The cable guide 33 can be lifted upward by human power in the simplest device. When a multiple seed string seeding device is used, it can be configured to be pulled up by a common motor. The seed string cutting device CU is provided with a disk cutter 37.
In addition, although the example which uses a disk cutter was shown in this Example, when the material of a seed string is cut | disconnected easily with a heat | fever, a heater can also be used as a cutter.
[0009]
The main shaft 9 of the seed string seeding device is pulled in the direction indicated by the arrow B in FIG. The seed string 1 stored in a seed string reel (not shown) is guided to the surface of the planting main roller 5 through the guide ring 15, and the seed string 1 pressed against the planting main roller 5 by the pressing roller 3 is the planting main roller. 5 is pressed against the trench 10 a of the soil 10.
The seed string 1 is embedded in the soil for a predetermined length, and when the seed string 1 is cut, the seed string cutting device CU described above is operated to cut the seed string 1. FIG. 1 shows a state where the seed string is cut.
[0010]
Next, the operation of the seed string cutting device will be described with reference to FIGS. In FIG. 2, when the rope 36 is pulled upward, the hook portion 39 b at the lower end of the lever 39 rotates in the clockwise direction indicated by the broken line in FIG. 2 to lift the seed string 1 and press the seed string 1 against the cutter 37. . FIG. 3 shows a state immediately before the lever 39 starts to rotate, and FIG. 4 shows a state in which the lever 39 presses the seed string 1 against the cutter 37 and cuts it.
[0011]
【The invention's effect】
As explained in detail above, the seed string cutting device according to the present invention is:
A seed string cutting device for cutting a seed string supplied to the soil from a seed string reel and embedded at a seeding end point,
A means for holding the seed string in a plane intersecting the direction of the arranged seed string and scooping up a part of the seed string to contact a cutter provided on the soil surface.
The means for bringing the seed string into contact with the cutter is a lever that has a hook that moves in a plane intersecting the direction of the seed string, moves under the seed string, and scoops up a part of the seed string, Can be provided in the movement path of the lever.
Since the cutter is provided on the soil surface, it is not damaged by contact with the soil. When sowing using a trucker or the like, the driver can cut the seed string by an operation from the trucker, and does not need to cut the seed string from the trucker with a blade or the like.
