Abstract
Description
Technical Field
[0001] The present invention relates to a seeder for sowing seeds on the ground.
Background Art
[0002] Conventionally, a seeder has been known as a machine for manually sowing seeds on the ground. For example, Patent Document 1 below discloses a manual seed sower as a seeder configured to extrude seeds introduced from a seed inlet and guided to a seed standby section into the ground through a seed feeding section with a seed extrusion rod. In this case, this manual seed sower can sow a plurality of seeds (for example, 3 seeds) at a single location simultaneously by bundling a plurality (for example, 3 units) of manual seed sowers.

Patent Document 1
[0004] However, in the manual seed sower described in Patent Document 1 above, when bundling a plurality of manual seed sowers, it is necessary to connect the respective seed extrusion rods so that they can be interlocked, which complicates the configuration. In addition, since the seed standby section and the seed feeding section are formed with a large diameter, there is a problem that the interval between the sown seeds becomes wide and the utilization efficiency of the farmland is lowered.
[0005] The present invention has been made to address the above problems, and an object thereof is to provide a seeder that can sow a plurality of seeds simultaneously at positions close to each other with a simple configuration.
Summary of the Invention
[0006] In order to achieve the above object, a feature of the present invention is a seeder for sowing seeds on the ground, which includes a seed guide tube formed in a cylindrical shape extending upward with respect to the ground and guiding seeds from above downward, and a cylindrical discharge portion provided at the lower end of the seed guide tube and discharging the seeds that have fallen inside the seed guide tube toward the ground. The discharge portion has a plurality of discharge guide paths whose interiors are partitioned into at least two or more sections along the vertical direction and have discharge ports for discharging seeds independently onto the ground.
[0007] According to this, since the seeder has a plurality of discharge guide paths whose interiors are partitioned into at least two or more sections along the vertical direction and have discharge ports for discharging seeds independently onto the ground in the cylindrical discharge portion that discharges seeds toward the ground, a plurality of seeds can be sown simultaneously at positions close to each other with a simple configuration.
[0008] Another feature of the present invention is that in the seeder, the seed guide tube has a plurality of in-tube guide paths whose interiors are partitioned into at least two or more sections along the vertical direction and guide seeds independently to the plurality of discharge guide paths respectively.
[0009] According to this, since the seeder has a plurality of in-tube guide paths whose interiors are partitioned into at least two or more sections along the vertical direction and guide seeds independently to the plurality of discharge guide paths respectively, seeds can be surely guided to the plurality of discharge guide paths respectively.
[0010] Another feature of the present invention is that in the seeder, at least one of the discharge guide path and the in-tube guide path has a protruding portion where a part of the side wall protrudes to the side opposite to the adjacent guide path.
[0011] According to this, since a part of the side wall in at least one of the discharge guide path and the in-tube guide path of the seeder has an overhanging portion that projects to the side opposite to the adjacent guide path, seeds discharged from the discharge guide paths adjacent to each other can be sown at positions where they do not approach each other and are separated, making it easier to perform the thinning operation. That is, in the seeding operation (for example, the seeding operation of corn), the sown seeds do not always germinate well. For this reason, in the seeding operation, a plurality of seeds are sown in one place in advance, and later, a thinning operation is performed to leave only the well-germinated buds and remove the other buds. In this thinning operation, it is difficult to perform the thinning operation if the buds germinate at positions close to each other. However, in the seeder according to the present invention, since a plurality of seeds are sown in an appropriate positional relationship where they are not too close or too far from each other, the thinning operation can be made easier.
[0012] Another feature of the present invention is that, in the seeder, further, a seed receiving portion that receives seeds and guides them to the in-tube guide path is provided. The seed receiving portion has a plurality of receiving guide paths that are partitioned into at least two or more sections whose interiors extend along the vertical direction and guide the seeds to the plurality of in-tube guide paths independently. The plurality of receiving guide paths each have a receiving port that opens larger than the cross-sectional area of the in-tube guide path.
[0013] According to this, since the seeder includes a seed receiving body that has a receiving port that opens larger than the cross-sectional area of the in-tube guide path and guides the seeds to the in-tube guide path, the operator can easily introduce the seeds into each in-tube guide path, improving workability.
[0014] Another feature of the present invention is that, in the seeder, further, an extruder that extrudes the seeds guided to the discharge portion against the ground is provided.
[0015] According to this, since the seeder is provided with an extruder that extrudes the seeds guided to the discharging part onto the ground, the seeds can be surely placed in the ground. In this case, the extruder may extrude the respective seeds present in the plurality of discharge guide paths into the ground together by a common extrusion means, or may extrude each seed present in each discharge guide path into the ground by an individual extrusion means.
[0016] Another feature of the present invention is that, in the seeder, the plurality of discharge guide paths are formed at positions separated from each other with a gap therebetween.
[0017] According to this, since the seeder has the plurality of discharge guide paths formed at positions separated from each other with a gap therebetween, the seeds discharged from the adjacent discharge guide paths can be sown at positions where they do not approach each other and are separated, and it is possible to facilitate the thinning operation.
[0018] Another feature of the present invention is that, in the seeder, at least a part of the discharging part is formed to be transparent.
[0019] According to this, since at least a part of the discharging part of the seeder is formed to be transparent, the state of the seeds guided into the discharging part can be confirmed from the outside, and the accuracy of the seeding operation can be improved.

Embodiments for Carrying out the Invention
[0021] Hereinafter, an embodiment of the seeder according to the present invention will be described with reference to the drawings. FIG. 1 is a front view showing a schematic of the external configuration of the seeder 100 according to the embodiment of the present invention. Further, FIG. 2 is a side view showing a schematic of the external configuration of the seeder 100 shown in FIG. 1. Further, FIG. 3 is a partially broken rear view showing a schematic of the external configuration of the seeder 100 shown in FIG. 1. Further, FIG. 4 is a front view of the seeder 100 shown in FIG. 1 with the biasing body 113 and the grounding tool 140 omitted respectively.
[0022] (Configuration of the seeder 100) This seeder 100 is an agricultural implement used for an operator to manually sow seeds on the ground of a field. The seeder 100 is mainly configured to include a seed guide tube 101, a discharging part forming body 110, a pushing tool 120, and a grounding tool 140 respectively.
[0023] The seed guide tube 101 is a component for receiving the seeds to be sown in the field and guiding them to the discharging part forming body 110, and is formed of a metal material (for example, an aluminum material or a stainless steel material, etc.) into a cylindrical shape extending in the vertical direction. Specifically, the seed guide tube 101 is configured to include a main body part 102 and a seed receiving part 106 respectively.
[0024] The main body portion 102 is a portion for guiding the seeds introduced into the seed guide tube 101 to the discharge portion forming body 110, and is formed in a cylindrical shape extending in the vertical direction. In the present embodiment, the main body portion 102 is formed with a square cross-sectional shape. In this case, on the front wall surface of the main body portion 102, an inclined portion 102a is formed in the lower portion thereof that bends toward the back side, and the internal space is formed to be constricted. Further, on this inclined portion 102a, four bolts 103 for attaching a grounding tool 140 described later are provided in a protruding state.
[0025] On the other hand, on the back wall surface of the main body portion 102, a notch portion 102b is formed in the lower portion thereof with the central portion in the left-right direction being notched in a substantially triangular shape. The interior of this main body portion 102 is partitioned by a partition plate 104 extending in the vertical direction into a first in-tube guide path 105a and a second in-tube guide path 105b, which are two regions when viewed from the front.
[0026] The partition plate 104 is a component for partitioning the inside of the main body portion 102 to form the first in-tube guide path 105a and the second in-tube guide path 105b respectively, and is composed of a plate-like body made of metal (for example, aluminum or stainless steel) extending along the vertical direction inside the main body portion 102. This partition plate 104 is provided at the central portion in the left-right direction when viewed from the front inside the main body portion 102, and the upper end portion extends to the upper end portion of the main body portion 102 and the lower end portion extends to the upper end portion of the notch portion 102b slightly above the lower end portion of the main body portion 102.
[0027] The first in-tube guide path 105a and the second in-tube guide path 105b are spaces for independently guiding seeds to the discharge portion forming body 110 inside the main body portion 102, and are formed to extend in the vertical direction inside the main body portion 102. These first in-tube guide path 105a and second in-tube guide path 105b are formed to have the same size and are adjacent to each other in the left-right direction when viewed from the front of the main body portion 102.
[0028] The seed receiving part 106 is a part for receiving seeds from an operator and guiding them to the main body part 102, and is formed in a cylindrical shape extending in the vertical direction. In this case, the seed receiving part 106 is formed in a conical shape with a cross-sectional area that expands from the lower opening to the upper opening. Further, the inside of the seed receiving part 106 is partitioned by a partition plate 107 extending in the vertical direction into a first receiving guide path 108a and a second receiving guide path 108b, which are two regions on the left and right in a front view. This seed receiving part 106 is integrally formed with the seed guide pipe 101.
[0029] The partition plate 107 is, like the partition plate 104, a part for partitioning the inside of the seed receiving part 106 to form the first receiving guide path 108a and the second receiving guide path 108b respectively, and is composed of a plate-like body made of metal (for example, aluminum or stainless steel, etc.) extending along the vertical direction in the seed receiving part 106. This partition plate 107 is provided at the center in the left-right direction in a front view within the seed receiving part 106, with the upper end extending to the upper end of the seed receiving part 106 and the lower end extending to the upper end of the main body part 102 and being connected to the partition plate 104.
[0030] The first receiving guide path 108a and the second receiving guide path 108b are spaces for independently guiding seeds to the first in-pipe guide path 105a and the second in-pipe guide path 105b respectively within the seed receiving part 106, and are formed extending in the vertical direction within the seed receiving part 106. These first receiving guide path 108a and second receiving guide path 108b are formed with the same size adjacent to each other in the left-right direction in a front view of the seed receiving part 106. In this case, the first receiving guide path 108a and the second receiving guide path 108b are each formed with a first receiving opening 109a and a second receiving opening 109b that open with a cross-sectional area that expands greatly upward as the seed receiving part 106 is formed with a cross-sectional area that expands greatly upward.
[0031] As shown in FIGS. 5 to 7 respectively, the discharge part forming body 110 is a component that forms a discharge part 111 and an extrusion rod guide part 116, and is formed by bending a plate-like body made of metal (for example, aluminum or stainless steel) into a U-shaped (U-shaped) shape. That is, the discharge part forming body 110 is formed in a groove shape in which side walls 110b and 110c facing each other stand upright at both edge parts of a flat back plate 110a. In this case, the lower parts of the side walls 110b and 110c facing each other of the discharge part forming body 110 are cut out so as to be sharp toward the lower end part, and the discharge part 111 is formed in the inner space of this cut-out part, and the extrusion rod guide part 116 is formed in the upper space of this discharge part 111.
[0032] This discharge part forming body 110 is attached to the lower part on the back surface of the seed guide tube 101 via a rivet (not shown). In this case, the discharge part forming body 110 is attached in a state where the discharge part 111 projects and is exposed below the seed guide tube 101, and the extrusion rod guide part 116 is covered by the back surface of the seed guide tube 101.
[0033] The discharge part 111 is a space that temporarily holds the seeds S that have fallen into the seed guide tube 101 and in which the extrusion rods 123 and 124 described later slide respectively. It is partitioned by a partition wall 112 and is closed in an openable and closable manner by a biasing body 113.
[0034] The partition wall 112 is a component for partitioning the inside of the discharge part 111 into a first discharge guide path 114a and a second discharge guide path 114b, which are two regions in the left-right direction in a front view. It is formed in a U-groove shape with a cross-sectional shape obtained by bending a plate-like body made of metal (for example, aluminum or stainless steel) into a U-shaped (U-shaped) shape. In this case, one end side of both end parts of the side walls 112a and 112b facing each other of the partition wall 112 is curved inward, and the respective tip parts are in close contact with each other and closed.
[0035] As a result, the partition wall 112 has an overhanging portion 112c formed such that the side walls 112a and 112b on one end side bulge outward toward the other end side. Further, the partition wall 112 is formed such that the side walls 112a and 112b extend parallel to each other from the overhanging portion 112c toward the other end, and the tip portion 112d, which is the other end, opens downward. In this case, the partition wall 112 has an inclined surface formed at the opening 112e, which is the edge of the side walls 112a and 112b, and the inclined surface inclines from the one end side toward the back plate 112f on the side opposite to the opening 112e toward the other end side.
[0036] This partition wall 112 is attached by a rivet (not shown) at the center in the left - right direction in a front view within the discharge portion 111. In this case, one end of the partition wall 112 abuts against the lower end of the partition plate 104 of the seed guide tube 101. Further, the tip portion 112d on the side opposite to the overhanging portion 112c of the partition wall 112 is located inside the end of the discharge portion 111. Due to these, a first discharge guide path 114a and a second discharge guide path 114b are respectively formed outside each of the side walls 112a and 112b of the partition wall 112 within the discharge portion 111.
[0037] The biasing body 113 is a component that elastically covers the opening portion of the discharge portion 111 and is composed of a transparent and flexible resin plate - like body. In the present embodiment, the biasing body 113 is composed of a rectangular plate - like body in a front view of the biasing body 113. One end side of this biasing body 113 is attached to the inclined portion 102a of the seed guide tube 101, and the other end abuts against the inner surface of the back plate 110a of the discharge portion forming body 110 at substantially the same position as the tip portion 112d of the partition wall 112.
[0038] That is, the biasing member 113 is elastically abutted against the back plate 110a in a cantilever state. In this case, the plate surface of the biasing member 113 is in contact with the opening 112e of the partition wall 112. Due to these, the first discharge guide path 114a and the second discharge guide path 114b are formed as spaces elastically closed by the biasing member 113. Further, the biasing member 113 is held in a state where one end side thereof is sandwiched between the inclined portion 102a of the seed guide tube 101 and the attachment body 142 of the grounding tool 140 described later.
[0039] The first discharge guide path 114a and the second discharge guide path 114b are spaces for temporarily holding the seeds S that have fallen from the first internal pipe guide path 105a and the second internal pipe guide path 105b respectively, and are formed to extend vertically on both sides of the partition wall 112 within the discharge portion 111. These first discharge guide path 114a and second discharge guide path 114b are formed adjacent to each other via the partition wall 112 at positions adjacent to each other and have the same size. In this case, the lower portions of the first discharge guide path 114a and the second discharge guide path 114b are elastically closed by the biasing member 113, and the biasing member 113 elastically deforms so that the tip portion is separated from the back plate 110a, thereby forming the discharge port 115.
[0040] The extrusion rod guide portion 116 is a portion that slidably supports the extrusion rods 123, 124, and is formed in a cylindrical shape above the discharge portion 111. The extrusion rod guide portion 116 communicates with the discharge portion 111 and guides the extrusion rods 123, 124 in the vertical direction so that the tip portions of the extrusion rods 123, 124 protrude in and out of the discharge portion 111.
[0041] The extruder 120 is a tool for extruding the seeds S temporarily held in the first discharge guide path 114a and the second discharge guide path 114b within the discharge portion 111 to the outside, as shown in FIGS. 8(A) and 8(B) respectively, and is formed in a rod shape extending in the vertical direction. More specifically, the extruder 120 is configured to include an operation rod 121 and extrusion rods 123, 124 respectively.
[0042] The operating rod 121 is a component for operating the extrusion rods 123 and 124 in the vertical direction respectively, and is formed by shaping a metal material (for example, aluminum material or stainless steel material, etc.) into a rod shape extending in a long length with a square cross-sectional shape. An annular handle 122 for an operator using the seeder 100 to grip and operate the operating rod 121 is provided at the upper end of this operating rod 121.
[0043] The extrusion rods 123 and 124 are components for extruding the seeds S held in the first discharge guide path 114a and the second discharge guide path 114b to the outside respectively, and are formed by shaping a metal material (for example, aluminum material or stainless steel material, etc.) into a rod shape extending in a long length with a square cross-sectional shape. In this case, the extrusion rod 123 is a component for extruding the seeds S in the first discharge guide path 114a to the outside, and the extrusion rod 124 is a component for extruding the seeds S in the second discharge guide path 114b to the outside. These extrusion rods 123 and 124 are attached to both side surfaces so as to sandwich the operating rod 121 by double-sided tape, adhesive or welding and are integrated with the operating rod 121.
[0044] Also, the extrusion rods 123 and 124 are formed such that the tip portions for extruding the seeds S have a smaller cross-sectional area than the cross-sectional area of the upper portion of the respective tip portions and the tip portions are sharpened. Further, the extrusion rods 123 and 124 are formed to have a length that abuts against a stopper 131 (described later) provided on the back surface of the seed receiving portion 106 in the raised position. This extruder 120 has a lower portion slidably penetrating through an extrusion rod guide portion 116 in a discharge portion forming body 110, and an upper portion slidably penetrating through an extrusion rod support portion 130 provided on the back surface of the seed receiving portion 106 and being supported.
[0045] The extrusion rod support portion 130 is a component for supporting the upper portion of the extruder 120. Specifically, the extrusion rod support portion 130 is formed by attaching a plate-like body made of metal (for example, made of aluminum or stainless steel, etc.) bent into a hat shape (rectangular wave shape) to the back surface of the seed receiving portion 106 to form a through hole through which the extruder 120 slides.
[0046] The stopper 131 is a component for restricting the upward movement of the extruder 120, and is configured by attaching a block body made of metal (for example, aluminum or stainless steel, etc.), which is a rectangular parallelepiped in this embodiment, to the back surface of the seed receiving portion 106. In this case, the stopper 131 is attached above the extrusion rod support portion 130 and on the advancing paths of the extrusion rods 123 and 124, respectively. Thereby, the stopper 131 restricts the upward movement of the extruder 120 when the upper end portions of the extrusion rods 123 and 124 in the ascending extruder 120 abut against it.
[0047] The grounding tool 140 is a component for stably standing the seeder 100 on the ground, and is mainly composed of a grounding plate 141 and a mounting body 142.
[0048] The grounding plate 141 is a component that abuts against the ground, and is configured by forming a through hole through which the discharge portion 111 can penetrate in a plate-shaped body made of metal (for example, aluminum or stainless steel, etc.).
[0049] The mounting body 142 is a component for attaching the grounding plate 141 to the discharge portion forming body 110, and is configured by forming a plate-shaped body made of metal (for example, aluminum or stainless steel, etc.) into a cylindrical shape that can be fitted around the inclined portion 102a of the seed guide tube 101. The mounting body 142 has the grounding plate 141 attached to its lower end portion by welding, and is configured by forming through holes through which four bolts 103 penetrate in the portion covering the inclined portion 102a.
[0050] That is, the mounting body 142 is detachably attached to the inclined portion 102a by the four bolts 103 provided on the inclined portion 102a passing through and being tightened with nuts. Further, the mounting body 142 is configured such that an opening 142a is formed in a portion facing the biasing body 113 so that the biasing body 113 is exposed.
[0051] (Operation of the seeder 100) Next, the operation of the seeding machine 100 configured as described above will be explained. First, the operator prepares the seeding machine 100 and a large number of seeds to be sown in the field using the seeding machine 100. Next, the operator inserts the discharge part 111 in the seeding machine 100 into the ground.
[0052] Specifically, the operator holds the handle 122, lifts the entire seeding machine 100, and inserts the seeding machine 100 into the position where the seeds are to be sown. As a result, after the discharge part 111 of the seeding machine 100 starts to be inserted into the ground, the seeding machine 100 is inserted into the ground until the grounding plate 141 hits the ground. That is, the seeding machine 100 assumes an upright posture with the discharge part 111 below the grounding plate 141 entering the ground.
[0053] Next, the operator respectively throws the seeds into the first receiving port 109a and the second receiving port 109b of the seed receiving part 106. As a result, the seeds thrown into the first receiving port 109a fall to the bottom of the first discharge guide path 114a through the first receiving guide path 108a and the first internal pipe guide path 105a, respectively. Also, the seeds thrown into the second receiving port 109b fall to the bottom of the second discharge guide path 114b through the second receiving guide path 108b and the second internal pipe guide path 105b, respectively.
[0054] Next, the operator arranges the seeds in the ground. Specifically, the operator holds the handle 122 and pushes down the extruder 120. As a result, as shown in FIG. 7, the seeding machine 100 causes the extrusion rods 123 and 124 to descend through the descent of the operation rod 121 and enter the first discharge guide path 114a and the second discharge guide path 114b, respectively. Then, the extrusion rods 123 and 124 elastically deform the tip end side of the biasing body 113 in a direction away from the back plate 110a of the discharge part forming body 110 in the first discharge guide path 114a and the second discharge guide path 114b to form the discharge port 115, and push out various seeds S located near the discharge port 115 through the discharge port 115.
[0055] As a result, the seeds S located in the first discharge guide path 114a and the second discharge guide path 114b are pushed into the ground. In this case, since the tip portions of the extrusion rods 123 and 124 protrude beyond the discharge port 115, the seeds S located in the first discharge guide path 114a and the second discharge guide path 114b are pushed to positions at a depth deeper than the discharge port 115.
[0056] Next, the operator removes the seeder 100 from the position where the seeds S were discharged. Specifically, after the operator grips the handle 122 and lifts the extruder 120, the operator then lifts the entire seeder 100. As a result, the tip portions of the extrusion rods 123 and 124 inserted into the ground rise as the operating rod 121 rises and return to the first discharge guide path 114a and the second discharge guide path 114b, and return to the extrusion rod guide portion 116 through the first discharge guide path 114a and the second discharge guide path 114b, respectively.
[0057] In this case, the soil adhering to each of the four side surfaces of the extrusion rods 123 and 124 is scraped off by the lower end portion of the back plate 110a of the discharge portion forming body 110, the lower end portions of the side walls 110b and 110c, and the lower end portion of the biasing body 113. Further, the biasing body 113 returns to a state in which the tip portion that was elastically deformed when the extrusion rods 123 and 124 were respectively accommodated in the first discharge guide path 114a and the second discharge guide path 114b is elastically in close contact with the back plate 110a of the discharge portion forming body 110.
[0058] Then, thereafter, the seeder 100 is removed from the ground as the entire seeder 100 is lifted. As a result, the seeder 100 is removed from the position where the seeds S were discharged. If there is a place to sow the next seeds, the operator can carry the seeder 100 to the next sowing place and perform the sowing operation in the same manner.
[0059] As can be understood from the above operation description, according to the above embodiment, in the seeder 100, the inside of the cylindrical discharge part 111 that discharges seeds toward the ground is partitioned into two in the vertical direction, and the two first discharge guide paths 114a and the second discharge guide path 114b having discharge ports 115 that independently discharge seeds to the ground are provided. Therefore, a plurality of seeds can be sown simultaneously at positions close to each other with a simple configuration.
[0060] Furthermore, in implementing the present invention, it is not limited to the above embodiment, and various changes can be made without departing from the object of the present invention.
[0061] For example, in the above embodiment, the seeder 100 partitions the inside of one discharge part 111 into the first discharge guide path 114a and the second discharge guide path 114b, which are two regions. However, the seeder 100 may be configured by partitioning the inside of one discharge part 111 into at least two or more regions. Therefore, the seeder 100 can also partition the inside of one discharge part 111 into three or four regions.
[0062] Also, in the above embodiment, the seed guide pipe 101 partitions the inside into two regions, the first in-pipe guide path 105a and the second in-pipe guide path 105b, by the partition plate 104. However, the inside of the seed guide pipe 101 is not limited to being partitioned into two regions, and can be partitioned into a number corresponding to the number of partitions in the discharge part 111. Also, the seed guide pipe 101 can be configured as a single space without partitioning the inside. In this case, the operator will carefully put the seeds into the seed guide pipe 101 so that the seeds S enter the first discharge guide path 114a and the second discharge guide path 114b in the discharge part 111, respectively.
[0063] Also, the seed guide pipe 101 can be configured as a number of pipes corresponding to the number of partitions in the discharge part 111, that is, the first in-pipe guide path 105a and the second in-pipe guide path 105b as independent pipes. Also, the seed guide pipe 101 can be configured in a flexible or bendable tube shape or hose shape using a resin material or a cloth material in addition to a metal material.
[0064] Also, in the above embodiment, the seed receiving portion 106 is partitioned into two regions, i.e., a first receiving guide path 108a and a second receiving guide path 108b, by a partition plate 107 inside. However, the inside of the seed receiving portion 106 is not limited to being partitioned into two regions, and can be partitioned into a number corresponding to the number of partitions within the discharging portion 111. Also, the seed receiving portion 106 can be configured as a single space without partitioning inside. In this case, the operator has to carefully put seeds into the seed receiving portion 106 so that the seeds enter the first discharging guide path 114a and the second discharging guide path 114b within the discharging portion 111 respectively.
[0065] Also, in the above embodiment, the partition plate 107 of the seed receiving portion 106 is formed to extend up to the upper end portion of the seed receiving portion 106. However, the partition plate 107 of the seed receiving portion 106 can also be provided in a state where it does not reach the upper end portion of the seed receiving portion 106. According to this, the first receiving port 109a and the second receiving port 109b will be formed inside the seed receiving portion 106, and the operator can put his hand into the seed receiving portion 106 to put in seeds, and can prevent the seeds from overflowing outside the seed receiving portion 106.
[0066] Also, in the above embodiment, the seeder 100 is configured to include a seed receiving portion 106. However, the seeder 100 can also be configured by omitting the seed receiving portion 106.
[0067] Also, in the above embodiment, the partition wall 112 is configured to include an overhanging portion 112c. Thereby, among the seeds that have fallen through the first in-tube guide path 105a, the overhanging portion 112c bounces the seeds that have collided with the overhanging portion 112c to the side opposite to the second in-tube guide path 105b, and among the seeds that have fallen through the second in-tube guide path 105b, the overhanging portion 112c bounces the seeds that have collided with the overhanging portion 112c to the side opposite to the first in-tube guide path 105a, so that the positions where the two seeds are sown can be separated from each other.
[0068] That is, the first internal guide path 105a and the second internal guide path 105b are configured to include overhanging portions that protrude to the side opposite to the adjacent internal guide path, so that the positions of the seeds S sown through the respective pipe paths can be separated from each other. However, the seeder 100 can also be provided with overhanging portions in the first discharge guide path 114a and the second discharge guide path 114b. Further, this overhanging portion can be provided only on one of the guide paths adjacent to each other.
[0069] Also, in the above embodiment, the partition wall 112 has two side walls, a side wall 112a and a side wall 112b, and these two side walls are formed at positions separated from each other. Thereby, the partition wall 112 can separate the positions where the two seeds S are sown from each other. However, it is a matter of course that the partition wall 112 may be composed of one side wall. According to this, the first discharge guide path 114a and the second discharge guide path 114b are not separated from each other, are formed adjacent to each other, and the positions where the two seeds S are sown can be brought closer to each other.
[0070] Also, in the above embodiment, the seeder 100 is configured to include an extruder 120. However, the seeder 100 can be configured by omitting the extruder 120. In this case, the seeder 100 can be configured such that the discharge port 115 is always open.
[0071] Also, in the above embodiment, the discharge unit 111 is configured to provide a common discharge port 115 for the first discharge guide path 114a and the second discharge guide path 114b. However, the discharge unit 111 can also be configured to provide a discharge port 115 for each of the first discharge guide path 114a and the second discharge guide path 114b.
[0072] Also, in the above embodiment, the discharge unit 111 is configured such that the internal state can be visually recognized from the outside by configuring the biasing body 113 to be transparent. However, the discharge unit 111 can also be configured such that the internal state cannot be visually recognized from the outside by configuring the biasing body 113 with an opaque material (for example, a metal material).
[0073] In addition, in the above-described embodiment, the seeder 100 is configured to include the grounding member 140. However, the seeder 100 can also be configured by omitting the grounding member 140.
