Description

[Detailed Description of the Invention] The present invention relates to a furrow tool used for sowing seeds at regular intervals in rows of soil filled in a seedling box.

Prior to the above-mentioned row sowing, conventionally, first, a leveling tool for leveling the bed soil was used to scrape off the excess bed soil in the seedling nursery box to level the top surface of the bed soil, and then a roller for making rows was used. The grooves are formed on the top surface of the bed using a groove shaping tool, and the grooves are shaped and fixed using a groove shaping tool.

In this way, three types of tools are prepared separately for a series of tasks such as leveling, groove cutting, shaping, and fixing, and these tools are replaced and used one after another, which is not only irrational, but also because there are a large number of tools, they are stored. There was also room for improvement.

This invention was devised in view of the above circumstances, and
It is an object of the present invention to provide a groove cutting tool that can perform the above series of operations rationally, and is also useful in terms of storage and use.

Therefore, the groove making tool according to the present invention forms a container-shaped main body from a pair of left and right vertical side plates each having a handle on the outer surface and a horizontal side plate continuous between the two vertical side plates. A roller for creating grooves is mounted between the vertical side plates, one edge of the horizontal side plate is made a flat edge for leveling the floor soil, and the outer surface of the horizontal side plate is formed by the roller. It is distinctive in that it is formed on an uneven surface that shapes and fixes the grooves.

An embodiment of the present invention will be described based on the drawings. Side plates 4, 4
It is a container-shaped main body consisting of a horizontal side plate 5 connected between both vertical side plates 4 and 4', and is integrally molded from a synthetic resin material.

Reference numeral 6 denotes a groove-forming roller that is mounted between the vertical side plates 4 and 4', and the outer peripheral surface of the roller 6 is provided with annular uneven portions so that the cross section forms a continuous wave shape with a constant pitch. a is formed.

Approximately half of the side plate 5 is smoothly curved, and the edge of the curved side plate portion on the side of the projections 3, 3' is formed into a flat edge for leveling the floor.

Further, approximately half of the remaining side plate 5 is formed into a rectangular box shape with the side facing the roller 6 open (see Fig. 5), and this box-shaped portion C is used as a fertilizer measuring cup. configured for use.

Further, a portion corresponding to the bottom plate in this box-shaped portion C is formed in a continuous wave shape corresponding to the uneven portion a of the roller 6, and the outer surface portion of the portion corresponding to the bottom plate is used for shaping and fixing the grooves. It is configured with an uneven surface d.

Next, a method of using the groove cutting tool having the above structure will be explained.

First, as shown in Figure 2A, place an appropriate amount of bed in the seedling box 7.
8, the protrusions 3, 3' are attached to the side walls 9, 9 of the seedling box 7.
' by placing it against the upper surface to define the insertion depth of the flat edge into the seedling nursery box 7, and by making the vertical side wall 4.4' come into contact with the inner surface of the side wall 9, 9' to position it in the left and right direction. In the state in which it was done,
Slide the main body A along the side wall 9.9'.

As a result, excess bed soil is scraped off by the flat edge, and the scraped-off excess bed soil is scooped into the container-shaped main body A, thereby leveling the top surface of the bed soil.

Next, as shown in FIG. 9' to define the insertion depth of the roller 6, and position the roller 6 in the left-right direction by bringing both end surfaces of the roller 6 into contact with the inner surface of the side wall 9.9'. Slide A.

As a result, the roller 6 rolls on the floor ±8, and grooves 10 are created by the uneven portions a.

Thereafter, as shown in FIG. 'Abut against the upper surface to define the insertion depth of the uneven surface d, and the vertical side plate 4
, 4' are brought into contact with the inner surfaces of the side walls 9, 9' and positioned in the left-right direction, and the main body A is similarly slid.

Thereby, the grooves 10 are shaped by the suppressing action of the uneven surface d, and are fixed so that the grooves 10 will not collapse unexpectedly during handling of the seedling raising box 7 before sowing work.

As mentioned above, the present invention includes a leveling tool for leveling the floor soil,
It is integrally equipped with a roller for creating grooves and a groove shaping tool for shaping and fixing the grooves.
A series of tasks such as leveling the soil bed prior to row sowing, creating grooves, and shaping and fixing the grooves can be performed extremely rationally by changing the posture of the groove cutting tool. Because of this structure, it is possible to provide a groove cutting tool that is excellent in terms of storage, can be manufactured at low cost, and is easy to handle and useful as a whole.
