Abstract

PROBLEM TO BE SOLVED: To provide a seed string sowing device with which the feed-out quantity of a seed string is made equal with quantity to be buried and unwanted tensile force is prevented from being loaded to the seed string. SOLUTION: In this seed string sowing device, a seed string 1 supplied from a seed string reel or the like is buried in soil 10 along a main planting roller 5 driven and rotated along the surface of soil while moving in sowing direction. In this case, the seed string 1 is constituted so as to be supplied just for the length corresponding to the moving amount of surface of the main planting roller 5 in contact with the surface of the main planting roller 5 through a presser roller 3 to be driven and rotated in press-contact with the surface of the main planting roller 5. The surface of the presser roller 3 is composed of an elastic member, and the surface of the main planting roller 5 is driven, and rotated in press-contact with and pressed onto the surface of soil by a spring in the case of sowing.

Description

Detailed Description of the Invention

[0001]

BACKGROUND OF THE INVENTION 1. Field of the Invention The present invention relates to a seed string sowing device for sowing vegetables and the like in a field with a seed string.

[0002]

2. Description of the Related Art A field such as a seed tape in which vegetable seeds are held at regular intervals on a tape, or a paper tape such as a non-woven fabric in which the seeds are wound and entwined with a thread (hereinafter collectively referred to as a seed string) The work of sowing is widely performed. In the conventional laying of the seed string, first, the tip of the seed string is fixed to the ridge with a wire or the like, and the seed string is placed along the drum of the device while manually moving the seeding device equipped with the seed string supply drum or moving the truck. The general method is to cover the soil sequentially while pressing it against the soil surface. In the seed string burying process using the device of the type described above, tension may be intermittently generated between the fixed end and the laying end of the tip of the seed string, and the seed string is moved in the soil in the buried soil. Can form spaces in the soil that compromise germination conditions. In extreme cases, seed strings may appear on the cover soil when the field is uneven.

[0003]

SUMMARY OF THE INVENTION It is an object of the present invention to provide a seed string sowing device in which the feeding amount of the seed string is the same as the amount to be buried and the seed string is not subjected to an unintended tension. is there.

In order to achieve the above-mentioned object, the seed string sowing device according to the present invention will be described as follows in association with embodiments. That is, in the seed string sowing device according to the present invention, the seed string 1 is moved in the seeding direction and driven to rotate along the soil surface.
A seed string sowing device to be buried in soil 10 along with the above, wherein the seed string 1 is pressed against the surface of the main planting roller 5 and is pressed to the surface of the main planting roller 5 by a pressing roller 3 which is driven to rotate. The seed string 1 having a length corresponding to the amount of movement of the surface of the main planting roller 5 is supplied. The surface of the pressing roller 3 is an elastic member,
It can be configured so as to be pressed so as to rotate following the surface of the main implantation roller 5. The main planting roller 5 can be configured to be pressed against the soil surface by a spring during sowing.

DETAILED DESCRIPTION OF THE PREFERRED EMBODIMENTS The present invention will be described below in detail with reference to the drawings. FIG. 1 is a schematic side view showing an embodiment of a seed string sowing device according to the present invention, with a part cut away. FIG. 2 is a schematic view showing the relationship between the main implanting roller and the seed string when the seed string sowing apparatus shown in FIG. 1 is viewed from the direction AA in FIG. FIG. 3 shows the part of the seed string buried in the soil. FIG. 4 is a plan view of an embodiment of the seed string seeding device according to the present invention, and FIG. 5 is a side view of the embodiment of the seeding device. A main shaft 9 and a pressing roller lever 13 are pivotally attached to the main frame 11 by a connecting shaft 8. The main shaft 9 is moved in the direction indicated by the arrow B by a truck or the like (not shown). A spring 19 is stretched between the main shaft 9 and the main frame 11, and a spring 18 is stretched between the pressing roller lever 13 and the main frame 11. Implanted main shaft 5 on shaft 22 fixed to main frame 11
Are rotatably provided. The main implantation roller 5 is provided with a pair of flanges 7, 7. Hubs 21, 21 are integrally provided on the flanges 7, 7. A pressing roller 3 whose surface is made of an elastic material is rotatably provided on the other end side of the pressing roller lever 13. Further, a guide ring 15 formed by processing a wire is provided at the tip of the pressing roller lever 13. The main shaft 9 is provided with a plow 17 as shown in FIGS. When the main shaft 9 is pulled by a truck or the like in the direction shown by the arrow B, the furrow groove 10a is formed by the tip of the plow 17 so that the seed string 1 is buried in the soil 10. Please refer to FIG. 4 and FIG. 5 for the shape of the plow 17. A mud remover 20 is provided at the rear end of the main frame 11 to remove the soil attached to the surface of the planting main roller 5.

The seed string 1 is wound around a reel (not shown), and is brought to the surface of the main implantation roller 5 from above in FIG. 1 through a guide ring 15. The seed string 1 is pressed against the surface of the main roller 5 by the pressing roller 3. A spring 19 hung between the main shaft 9 and the main frame 11 applies a counterclockwise rotational force to the main frame 11 in FIGS. 1 and 5, and urges the shaft 22 of the main implantation roller 5 toward the soil 10. . As a result, the main planting roller 5 is pressed against the surface of the soil 10. When the main shaft 9 is moved in the direction of the arrow B in FIG. 1, the ridge groove 10a is formed as described above, and the seed string 1 is pushed into the ridge groove 10a by the implantation main roller 5 and is pressed by a pressing roller (not shown). It is covered with soil as shown in 3. FIG.
As shown in, seeds 1a are wound in the seed string 1 at regular intervals. The pressing roller lever 13 is biased counterclockwise in FIGS. 1 and 5 by the spring 18 that is stretched between the main frame 11 and the pressing roller lever 13, and presses the pressing roller 3 against the surface of the implantation main roller 5. The seed string 1 guided to the surface of the main implantation roller 5 via the guide ring 15 is pressed against the main implantation roller 5 by the pressing roller 3.

[0007]

As described in detail above, the seed string sowing apparatus according to the present invention is a main planting roller for moving the seed string supplied from the seed string reel in the sowing direction and driven to rotate along the soil surface. Along the line, in a seed string sowing device to be buried in soil, the seed string is a pressing roller that is pressed against the surface of the main implantation roller and driven to rotate, and is pressed against the surface of the primary implantation roller to press the surface of the primary implantation roller. It is configured to supply a seed string having a length corresponding to the movement amount. Therefore, the seed string is pressed and embedded on the surface of the soil 10 by the rotation amount of the main planting roller. Even if the seed string 1 buried in the soil 10 is pulled from the left side in FIG. 1 for some reason, the seed string 1 is sandwiched between the main implantation roller 5 and the pressing roller 3, so that the seed string 1 It will not be withdrawn. In other words, the seed string 1 is accurately supplied to the soil 10 by the rotation amount of the main planting roller 5. Since the feeding amount of the seed string is the same as the amount to be buried, tension is not applied to the buried seed string. Therefore, problems such as the seed string moving in the soil to form a cavity around the seed string and floating on the soil surface are completely prevented.
