Description

Technical Field

[0001] The present invention relates to a hand-held seeder that allows a worker to plant one or several vegetable or flower seeds at a time in soil such as a field or a vegetable garden while standing.

Background Art

[0002] As a means for performing efficient seeding work, a large seeder that automates all the steps of the seeding operation and a hand-held seeder mainly used in home vegetable gardens and the like are known. This hand-held seeder is small and lightweight, so it is easy for beginners to handle, and because it saves space and is easy to store and carry, it is selectively used as a tool that can flexibly adjust the type and amount of seeds for small-scale work.

[0003] The functions required for this hand-held seeder include a function for adjusting the seeding depth for the purpose of improving the germination rate, a function for replacing the nozzle and hopper according to the size of the seeds to prevent clogging and uneven seeding, a function for controlling the number of seeds, and a vibration function for evenly sowing small seeds. However, as described in the effects of the invention in

[0008] of Patent Document 1, "being able to easily perform seeding work in a comfortable posture" can be said to be the first required function for any hand-held seeder. As a structure for performing seeding work in this comfortable posture, it is common for the hand-held seeder itself to be rod-shaped and have a certain length. As described in the known document 1, a method of filling a storage part provided near the ground with the seeds to be sown and sowing them one by one, or as shown in FIG. 1, a method of dropping the seeds onto the ground through the inside of a tubular seed supply member, where the end on the hand side of the tubular seed supply member serves as the seed inlet.

[0004] However, among the characteristics of seeds when using a hand-held seeder, there are those in which the orientation of the seeds is highly related to the germination rate. For example, in the case of pumpkins, in order to facilitate the roots to grow in the correct direction during germination, it is required to sow the seeds with the protruding part provided at one end of the elliptical shape of the seed facing downwards. In such a case, when using the method of filling the storage part as in the known document 1, it is necessary to incorporate a mechanism for adjusting the inclination or vibration that can adjust the orientation of the seeds in the filling part, and to use air flow or vibration on the way through which the seeds pass to guide the seeds to an appropriate orientation, resulting in the problem of complex structure. Also, in the method of dropping from the input port at hand as shown in FIG. 1, since the seeds are dropped into the holes with the inner diameter of the tubular seed supply member, there is a possibility that the orientation of the seeds may change freely when the seeds fall, and it is difficult to keep the orientation of the seeds constant, resulting in a problem.

Summary of the Invention

Problems to be Solved by the Invention

[0006] Therefore, an object of the present invention is to be able to sow seeds having a protruding shape at one end of an elliptical shape with the protruding shape direction at one end always facing downwards into the ground, and to achieve this effect only by adding a simple structure using inexpensive materials to a general hand-held seeder.

Means for Solving the Problems

[0007] In order to solve the above problems, the hand-held seeder of the present invention is a hand-held seeder provided with a seed inlet at one end of a tubular seed supply member and an openable and closable beak-shaped mechanism at the other end. An inner diameter changing member is inserted into the tube of the tubular seed supply member. The inner diameter changing member is a substantially square tube member having a lid portion with a seed inlet at one end, and is detachable from the hand-held seeder. The inner diameter of the seed inlet and the substantially square tube member of the inner diameter changing member is set to be smaller than the longitudinal length of the seed having a protrusion shape at one end of the elliptical shape and larger than the lateral length. Also, it is a hand-held seeder provided with a seed inlet at one end of a tubular seed supply member and an openable and closable beak-shaped mechanism at the other end. The inside of the tube of the tubular seed supply member is partitioned in the vertical direction, a second seed inlet and a second seed dropping path are provided, and the inner diameters of the second seed inlet and the second seed dropping path are set to be smaller than the longitudinal length of the seed having a protrusion shape at one end of the elliptical shape and larger than the lateral length.

Advantages of the Invention

[0008] In the hand-held seeder according to the present invention, by setting the inner diameter of the tubular seed supply member corresponding to the seed inlet and the seed dropping path for sowing seeds on the ground to be smaller than the longitudinal length of the seeds to be sown, it is possible to prevent the seeds introduced from the seed inlet from rotating by 90 degrees or more. When a seed having a protrusion shape at one end of the elliptical shape is inserted with the protrusion shape facing down, it is always possible to sow the seed on the ground with the protrusion shape facing down. Since the inner diameter of the tubular seed supply member, which is the seed inlet and the seed dropping path of a commercially available hand-held seeder, is generally the same size as the thickness of the tubular seed supply member to be used, a member for changing the inner diameter is detachably attached to the tubular seed supply member, or a part of the inside of the tube of the tubular seed supply member is partitioned to provide a second seed inlet and a second seed dropping path, and different seed inlets and seed dropping paths are provided according to the type of seeds, so that the types of seeds that can be sown with one hand-held seeder can be increased and the versatility can be enhanced. When using a method of filling seeds into a storage part near the ground as in the prior art document 1, adjustments such as incorporating a mechanism for inclination or vibration capable of adjusting the orientation of the seeds within the filling part, and guiding the seeds into an appropriate orientation by using air flow or vibration during the passage of the seeds are required. However, by utilizing the configuration of the present invention, it is possible to adjust the orientation of the seeds without using a complicated structure.

Modes for Carrying Out the Invention

[0010] An embodiment of the handheld seeder of the present invention will be described with reference to the drawings. However, the configurations, drawings, etc. described in this handheld seeder are not intended to limit the scope of this invention unless specifically described, and are merely illustrative examples. Fig. 1 shows a front view of a general hand-held seeder, and Fig. 2 shows a side view. In each figure, (a) shows the state before sowing seeds, and (b) shows the state during use when sowing seeds.

[0011] (Regarding the process of sowing with the hand-held seeder according to the present invention) As shown in Fig. 1(a) and Fig. 2(a), for the hand-held seeder according to the present invention, the upper part shown in the figure, which is one end of the tubular seed supply member 02, is used as the seed inlet 03, and a beak-shaped mechanism 04 is connected to the lower part shown in the figure, which is the other end. The hand-held seeder 01 is used by inserting the beak-shaped mechanism 04 into the ground such as a field where sowing is desired. The hand-held seeder 01 is provided with a handle 05 near the seed inlet 03, and the beak-shaped mechanism 04 is connected to a lever 06 provided near the handle 05 via a wire 07. As shown in Fig. 1(b) and Fig. 2(b), the operator can open the beak-shaped mechanism 04 by simultaneously grasping the handle 05 and the lever 06. By opening the beak-shaped mechanism 04, a sowing hole can be opened in the ground such as a field, and it has the function of dropping seeds from the seed inlet 02 into the sowing hole for sowing.

[0012] Fig. 3 shows the shape of the inner diameter changing member 08 used by inserting it into the hand-held seeder 01 as (a) a front view, (b) an enlarged top view, and (c) an enlarged bottom view. The inner diameter changing member 08 is an attachment for changing the inner diameter of the tubular seed supply member 02 corresponding to the path through which the seeds of the hand-held seeder 01 fall. A lid portion 10 is provided at one end of a square tube member 09 having an inner diameter smaller than the inner diameter of the tubular seed supply member 02. The lid portion 10 is circular with a diameter larger than that of the seed inlet 03 and is provided with a seed inlet 11 connected to the square tube member 09. The lid portion 10 functions as a stopper when the inner diameter changing member 08 is inserted from the end on the opposite side of the lid portion 10 through the seed inlet 03 of the hand-held seeder 01. As shown in FIG. 4, the lid portion 10 provided at one end of the inner diameter changing member 08 is inserted upward through the seed inlet 03 of the hand-held seeder 01. FIG. 4(a) shows a diagram during the insertion process, and (b) shows a diagram during use when sowing seeds after insertion. It is desirable to insert the inner diameter changing member 08 until the position where the end portion on the seed inlet 03 side of the hand-held seeder 01 is in close contact with the lid portion 10 of the inner diameter changing member 08. Then, as shown in FIG. 4(b), after the lid portion 10 of the inner diameter changing member 08 is brought into close contact with the end portion of the seed inlet 03 of the hand-held seeder 01, seeds are dropped from the seed inlet 11 provided in the lid portion 10 of the inner diameter changing member 08 according to the usage procedure of the hand-held seeder 01 described in

[0012] , and sowing is performed.

[0013] (Regarding the hand-held seeder) The hand-held seeder 01 used in the hand-held seeder according to the present invention is assumed to be a manual seeder as shown in FIGS. 1 and 2, in which seeds are sown one by one by being put into a seed inlet provided at the operator's hand, which is called a precision seeder, a dibbler, etc. As long as it is a seeder equipped with a straight pipe corresponding to the seed inlet and the seed dropping path of the present invention, the configuration of the seeder, the shape or the length of the members is not limited.

[0014] (Regarding the shape of the seed inlet and the tubular seed supply member) FIG. 5 shows (a) a top view of the hand-held seeder 01 and (b) a top view after the inner diameter changing member 08 is inserted into the hand-held seeder 01. The tubular seed supply member 02 of the handheld seeder 01 is a straight tube, and as shown in Fig. 5(a), it is common that the seed inlet 03 of the handheld seeder 01 has the same shape as the inner diameter of the tubular seed supply member 02. In this embodiment, as a means of changing the shape of the inner side of the seed inlet 03 of the handheld seeder 01 and the tubular seed supply member 02, the inner diameter changing member 08 is inserted into the handheld seeder 01 to make it replaceable. However, it does not prevent the structure from limiting the use from the beginning by making the shape of the inner side of the seed inlet 03 of the handheld seeder 01 and the tubular seed supply member 02 the same as the inner diameter of the inner diameter changing member 08.

[0015] (Regarding the inner diameter changing member) The inner diameter changing member 08 is provided with a lid portion 10 at one end of a square tube member 09 having an inner diameter smaller than the inner diameter of the tubular seed supply member 02 corresponding to the seed dropping path. The lid portion 10 is circular with a diameter larger than that of the seed inlet 03 and is provided with a seed inlet 11 connected to the square tube member 09. The dotted line portion in Fig. 5(b) is a line showing the seed inlet 03 through transmission. By closing the seed inlet 03 with the lid portion 10 provided in the inner diameter changing member 08, the path through which the input seeds fall to the ground can be changed into the square tube member 09. Also, as shown in the bottom view of the beak-shaped mechanism 04 of the handheld seeder 01 in Fig. 6(a) in the closed state and the bottom view when the beak-shaped mechanism 04 is opened after inserting the inner diameter changing member 08 into the handheld seeder 01 in Fig. 6(b), when the beak-shaped mechanism 04 is opened, the square tube member 09 is exposed. The length of the inner diameter changing member 08 is such that when the beak-shaped mechanism 04 is inserted into the ground, the end of the square tube member 09 does not touch the ground, like the end 12 of the inner diameter changing member shown by the dotted line portion in Fig. 4(b). This can prevent soil from entering the end of the square tube member 09 on the ground side and causing clogging, and at the same time, since the distance between the end of the square tube member 09 on the ground side and the ground is close, it can prevent the change in the direction of the sown seeds, which is desirable.

[0016] (Regarding the inner diameter of the inner diameter changing member) Fig. 7(a) is a cross-sectional view of the tubular seed supply member 02 in the handheld seeder 01 before inserting the inner diameter changing member 08 when seeds pass through it, and (b) is a cross-sectional view of the angular tube member 09 when seeds pass through it after inserting the inner diameter changing member 08. The size of the inner diameter of the angular tube member 09 will be described with reference to Fig. 7. As shown in Fig. 7(a), when the inner diameter of the tubular seed supply member 02 is larger than the longitudinal length of the pumpkin seed 13, when the pumpkin seed 13 falls with the protruding end 14 facing downwards, it can rotate freely. Therefore, like the pumpkin seed 13 located at the lower part shown in the figure, the protruding end 14 may face upwards. That is, the problem of always sowing the seeds with the protruding end 14 facing downwards into the ground cannot be solved. On the other hand, as shown in Fig. 7(b), when the inner diameter of the angular tube member 09 is set to be smaller than the longitudinal length of the pumpkin seed 13 and larger than the lateral length, and the pumpkin seed 13 falls with the protruding end 14 facing downwards, since the pumpkin seed 13 cannot rotate by more than 90 degrees, the protruding end 14 will always touch the ground. Therefore, by setting the seed inlet 11 of the inner diameter changing member 08 and the inner diameter of the angular tube member 09 to be larger than the minimum value of the longitudinal length of the seeds to be sown and smaller than the maximum value of the lateral length, it is possible to have the functions of the present invention. In this embodiment, since sowing of pumpkin seeds is assumed, an angular tube-shaped member is used in accordance with the shape of the flat seeds, but as long as the shape meets the requirements, it is not limited to this, such as a cylindrical shape.

[0017] (Regarding other embodiments) Although the above-described embodiment has a function of providing versatility by making the inner diameter changing member 08 detachable, as shown in FIG. 8, a partition member 15 having the same function as the inner diameter changing member 08 is added to the seed inlet 03 and the tubular seed supply member 02 connected to the seed inlet 03, and a pumpkin seed inlet 16 is provided, and it is also possible to adopt a configuration in which the seed inlet is changed according to the type of seeds to be sown. In the embodiment shown in FIG. 8, since it is not necessary to attach and detach the inner diameter changing member 08, the configuration is more efficient. Thus, the method of changing the inner diameter of the seed inlet 03 and the tubular seed supply member 02 connected to the seed inlet 03 is not limited to this.
