Description

Technology Field

[0001] The present invention is a device for sowing potatoes in furrows.

[0002] More specifically, it is a potato planter designed to adjust the planting depth according to the region and terrain, ensure that cut seed potatoes are planted correctly, and plant potatoes at uniform intervals. Background Technology

[0004] The method of planting potatoes is carried out by forming furrows in the field, digging the soil to a certain depth using a farming tool such as a hoe or a cultivator on the ridges formed between the two furrows to form a furrow, planting seed potatoes at regular intervals in the furrow, and then covering them with soil again.

[0005] As this work process is carried out manually by human labor, it is natural that work efficiency declines due to increased working time and costs. To address this, efforts have been made to mechanize potato planting, and numerous automatic potato planters are currently being developed.

[0006] As shown in the following patent documents 1 to 3, potato planters are towed by agricultural machinery such as a tractor to sow seeds.

[0007] For small-scale farmers or those planning to plant a small quantity of potatoes, purchasing a potato planter towed by agricultural machinery such as a tractor has the disadvantage of being quite burdensome.

[0008] Figure 1 is a conventional manual potato planter.

[0009] A conventional potato planter comprises a planter (1) consisting of a first planter (1a) and a second planter (1b) coupled to rotate around a hinge (C), a handle part (2) consisting of a first handle part (2a) and a second handle part (2b) extended from the planter (1); and an input hopper (3) that guides potatoes (4) to be inserted into the first planter (1a) and the second planter (1b).

[0010] In a conventional potato planter like this, a planting trowel (1) is inserted into a furrow formed as shown in FIG. 1 (a), and a potato (4) is inserted into an input hopper (3). Then, when the handle part (2) is gathered as shown in FIG. 1 (b), the planting trowel (1) rotates around the hinge (C) and opens up. At this time, the inserted potato is inserted into the planting hole formed by the planting trowel (1). When the potato planter is lifted upward in this state, the planting of the potato is completed.

[0011] Potatoes to be sown are usually not whole potatoes, but are cut into 2 to 4 pieces, and the cut potatoes are inserted into the sown holes formed by the sown trowel (1) as shown in Fig. 2 to be sown.

[0012] When planting is performed as in Fig. 2(a), the potato eyes are located on the lower side, which results in the sprouts not growing well. Therefore, although the cut potatoes should be inserted into the planting hole formed by the planting trowel (1) and planted as in Fig. 2(b), most of the cut potatoes are usually planted as in Fig. 2(a). This phenomenon is particularly pronounced in the case of potatoes cut into two pieces. Prior art literature

[0032] To fully understand the present invention, preferred embodiments of the invention are described with reference to the accompanying drawings. Embodiments of the present invention may be modified in various forms, and the scope of the present invention should not be interpreted as being limited to the embodiments described in detail below. These embodiments are provided to more completely explain the present invention to those with average knowledge in the art. Accordingly, the shapes of elements in the drawings may be exaggerated to emphasize clearer explanations. It should be noted that in each drawing, identical components may be depicted with the same reference numeral. Detailed descriptions of known functions and configurations that are deemed to unnecessarily obscure the essence of the present invention are omitted.

[0034] The present invention is a manual potato planter configured to adjust the planting depth of potatoes according to various environmental factors such as topography, climate, and soil, to ensure that cut seed potatoes are planted correctly, and to plant potatoes at uniform intervals.

[0035] The potato planter comprises a planter consisting of a first planter and a second planter that rotate around a hinge, and a handle portion extending from the planter and rotating the planter around the hinge, the handle portion consisting of a first handle portion and a second handle portion. The planter has a potato turning means formed on the inner side of the planter to temporarily settle a cut potato being fed in, and then drops the potato when the end of the planter is opened by rotating the planter around the hinge; a planting position marking means formed to rotate to mark the next planting position when the handle portion is operated to open the closed planter; and a planting hole adjustment means on one side of the planter that can adjust the depth of the planting hole formed by the planter.

[0037] Hereinafter, an embodiment of the potato planter of the present invention will be described in more detail with reference to the drawings illustrating the embodiment.

[0038] Referring to Figures 3 and 4,

[0039] The configuration of the potato planter of the present invention comprises: a planting trowel (10) consisting of a first planting trowel (11) and a second planting trowel (12) installed to rotate around a hinge (C); a handle part (20) consisting of a first handle part (21) and a second handle part (22) that extend from the planting trowel (10) and rotate the planting trowel (10) around the hinge (C); an input hopper (30) configured to allow potatoes to be easily fed into the planting trowel (10) composed of the first planting trowel (11) and the second planting trowel (12); a planting hole adjustment means (40) installed on the outer surface of the first planting trowel (11) of the planting trowel (10) to adjust the depth of the planting hole; and a cutting potato being fed in, installed on the inner surface of the first planting trowel (11) of the planting trowel (10), and then around the hinge (C) It includes a potato turning means (50) formed to drop when the end of the planting trowel (10) is rotated and spreads, and a planting position marking means (60) configured to rotate and mark the next planting position when the handle part (20) is operated to spread the closed planting trowel (10).

[0041] The above handle portion (20) has a handle length adjustment device (23) on each of the first handle portion (21) and the second handle portion (22) so that it can be conveniently used according to various body types (height differences).

[0042] Generally, there is a significant difference in height between men and women, and due to this, there is a disadvantage that the handle part (20) is inconvenient to use when it is constant.

[0043] In addition, when adjusting the depth of the seeding hole using the seeding hole adjustment means (40), the depth to which the seeding trowel (10) is inserted into the ground changes, so there is a need to adjust the length of the handle part (20), and there is a need to adjust the length of the handle part (20) due to geographical (environmental) factors such as the height difference of the furrow.

[0044] The first handle portion (21) and the second handle portion (22) of the above handle portion (20) are typically formed in the shape of a rod (pipe), and the handle length adjustment device (23) formed on each of the first handle portion (21) and the second handle portion (22) formed in the shape of a rod (pipe) can use various adjustment methods to adjust the length of the rod (pipe).

[0045] Various techniques for adjusting the length of a pole (pipe) are known, such as using a set screw or using a ball supported by elasticity. In particular, it is desirable to use a length adjustment method widely used in hiking sticks, but the adjustment method is not technically limited.

[0047] The above-mentioned planting hole adjustment means (40) is configured to allow the planting depth of potatoes to be adjusted according to various environmental factors such as terrain, climate, and soil, and is composed of a depth adjustment adjustment rod (41) that moves up and down along the outer surface of one side of the outer surface of a standard planting trowel (10) and is fixed at an arbitrary position.

[0048] Referring to FIGS. 5 to 8,

[0049] The above-mentioned seeding hole adjustment means (40) is composed of a depth adjustment adjustment rod (41) that adjusts the position of the seeding trowel (10) inserted into the ground by contacting the ground of the furrow, an up-and-down moving plate (42) formed to wrap around a part of the outer surface of the first seeding trowel (11) so that the depth adjustment adjustment rod (41) can move up and down along the outer surface of the first seeding trowel (11) of the seeding trowel (10), a guide hole (43) formed in the first seeding trowel (11) to guide the up-and-down moving plate (42) that moves up and down, and a moving plate fixing device (44) composed of a bolt and a nut that can fix the up-and-down moving plate (42) that moves up and down along the guide hole (43) at any position.

[0050] The depth adjustment guide (41) is installed at a predetermined angle to the first shovel (11) so that when the shovel (10) is inserted into the ground of the furrow, it is parallel to the ground.

[0052] The above seeding hole control means (40) is usually installed on the outer surface of the first seeding trowel (11) as shown in the attached drawing, but may also be installed on the outer surface of the second seeding trowel (12).

[0054] The above potato turning means (50) is configured to allow the cut potato to temporarily rest, and to drop when the end of the planting trowel (10) is rotated around the hinge (C) and the end is spread apart, thereby positioning the cut part of the potato in the downward direction (the ground of the planting hole).

[0055] Referring to FIGS. 5 to 8,

[0056] The above potato turning means (50) is installed on the inner surface of the first trowel (11) of the trowel (10), and is configured as a turning catch (51) such that when the end of the trowel (10) is closed as in FIG. 5 and FIG. 6, it becomes horizontal like the depth adjustment guide (41) of the trowel hole adjustment means (40), and when the end of the trowel (10) is opened for planting as in FIG. 8, it is tilted at a predetermined angle of inclination (θ) so that the cut potato slides down and falls.

[0057] The above-mentioned rotating stopper (51) is made of a fork-shaped plate as shown in FIG. 7 and is installed on the lower side of the hinge (C) so that when the end of the trowel (10) is closed, the potato does not fall downwards through the internal passage formed by the first trowel (11) and the second trowel (12), and when the end of the trowel (10) is open, the potato can fall downwards (see FIG. 8).

[0058] To explain in more detail,

[0059] As shown in FIG. 6, when the ends of the first planting trowel (11) and the second planting trowel (12) are closed, the potatoes are prevented from passing through by the rotating catch (51), which is the potato rotating means (50).

[0060] When the first planting trowel (11) and the second planting trowel (12) rotate around the hinge (C) and the ends spread apart, the passage formed by the first planting trowel (11) and the second planting trowel (12) gradually becomes larger, and when the first planting trowel (11) rotates around the hinge (C), the rotating catch (51), which is the potato rotating means (50), becomes inclined from a horizontal state and has an angle of inclination (θ), and as a result, the cut potato that is placed on the rotating catch (51), which is the potato rotating means (50), slides along the inclined rotating catch (51) and is placed in the planting hole on the lower side.

[0061] Potatoes cut by this process can be positioned so that the cut portion touches the ground of the planting hole, allowing the direction of the eye to be positioned upward. Additionally, the operator can check whether planting is being done in a desirable manner by looking at the cut potatoes placed on the rotating catch (51).

[0062] The above potato turning means (50) is usually installed on the inner side of the first seeding trowel (11) as shown in the attached drawing, but may also be installed on the inner side of the second seeding trowel (12).

[0064] The above-mentioned planting position marking means (60) is configured to ensure uniform spacing of the potatoes being planted, and is configured to rotate to mark the next planting position when the handle part (20) is operated to open the closed planting trowel (10).

[0065] Referring to FIGS. 3, FIGS. 4, FIGS. 9, and FIGS. 10,

[0066] The above-mentioned planting position marking means (60) is composed of a marking member (61) for marking the planting position, a marking rotating member (62) which is hinge-connected to the outer surface of the planting trowel (10) at one end so as to rotate and has the marking member (61) installed at the other end, and a marking link device (63) configured so that the marking rotating member (62) rotates according to the opening and closing of the handle part (20).

[0067] The above marking hole (61) is configured so that marking can be performed even with changes in the depth at which the seeding trowel (10) is inserted into the ground by the seeding hole adjustment means (40).

[0068] The above marking member (61) is composed of a tip member (61a) for marking and a screw shaft (61b) that enables the upper and lower height adjustment of the marking member (61).

[0069] The above marking rotating plate (62) is installed so that one end rotates around the first hinge axis (C1) on the outer surface of the second seed plate (12) of the seed trowel (10), and the other end is installed with a marking hole (61).

[0070] The above-mentioned marking rotator (62) is composed of a first rotator (62a) formed in a tubular shape, with one end installed to rotate on a first hinge shaft (C1); a second rotator (62b), with one end installed to be inserted into the first rotator (62a) and the other end having a screw hole (62c) to be screw-coupled with the screw shaft (61b) of the marking member (61); and a length adjustment member (62d) that fixes the second rotator (62b) inserted into the first rotator (62a).

[0071] The above length adjustment member (62d) can fix the second rotating member (62b) inserted into the first rotating member (62a) at any position, and usually a fixing bolt is used.

[0072] The above marking link device (63) is configured to allow a marking rotating plate (62) that rotates around a first hinge axis (C1) to rotate the handle portion (20) according to operation.

[0073] The above marking link device (63) is positioned so that the marking rotation plate (62) is positioned on the upper side when the lower part of the seeding trowel (10) is raised as in (a) of FIG. 9, and when the handle part (20) is closed so that the lower part of the seeding trowel (10) is spread out as in (b) of FIG. 9, the marking rotation plate (62) rotates so that the marking hole (61) marks the ground of the furrow.

[0074] This marking link device (63) is composed of a first marking link (63a) with one end connected to a second hinge shaft (C2) on one side of the upper part of the first seeding trowel (11), a second marking link (63b) with one end connected to a third hinge shaft (C3) on one side of the lower part of the second handle (22), and a third marking link (63c) with one end connected to a fourth hinge shaft (C4) on one side of the first rotating part (62a) of the marking rotating part (62) and the other end connected to a fifth hinge shaft (C5) together with the ends of the first marking link (63a) and the second marking link (63b).

[0075] Either of the first marking link (63a) and the second marking link (63b) connected to the fifth hinge axis (C5) is formed with an elongated hole.
