Description

Technology Field

[0001] The present invention relates to a furrow forming machine for cultivating upland rice.

[0002] More specifically, the present invention relates to a furrow forming machine for forming furrows that can be attached to a tractor for planting field rice. Background Technology

[0003] Upland rice refers to rice cultivated in fields. While it cannot be clearly distinguished from paddy rice from a botanical perspective, its characteristics can be distinctly differentiated from a horticultural perspective. Since upland rice is primarily planted in fields, it tends to be more resistant to environmental stress than paddy rice. Most upland rice is African rice, whereas paddy rice belongs to the Asian rice family. Globally, the growth characteristics of upland rice include weak stems, red grains, high shattering tendency, and dormancy. It is susceptible to disease and has low yields. Its quality and taste are also inferior to those of paddy rice. It thrives primarily in fields, wetlands, and freshwater environments. It has strong competitive power against weeds and is resistant to drought.

[0004] Compared to paddy rice, upland rice has thicker, wider, and larger leaves. It exhibits less tillering and has almost no regenerative capacity when the stem is cut. Its roots are thick and spread deeply, and it heads early and tends to grow tall. It has strong resistance to rice blast disease and high adaptability to specific soil types. Therefore, it is characterized by being primarily cultivated in water-scarce or drought-prone regions. In particular, soil moisture levels remain below field capacity, except during rainy periods. Upland rice cultivation sites are mostly flat or sloped. It is significant that upland rice is grown in areas where cultivating other alternative crops is difficult or in regions experiencing severe drought; while other upland crops can also be grown, it is cultivated for both food security and economic viability. Although there is almost no upland rice cultivation area in Korea, it is one of the most important food crops in West Africa (Sierra Leone, Guinea, Nigeria, Ivory Coast, and Liberia). Upland rice is cultivated as a major food source in South Asia, including India, Bangladesh, Sri Lanka, Nepal, and Bhutan, and in Southeast Asia, including Indonesia, Thailand, Myanmar, Cambodia, the Philippines, and Vietnam. It is also cultivated in Latin America, including Brazil, Bolivia, Peru, Colombia, Venezuela, Mexico, Guatemala, and Costa Rica.

[0005] Meanwhile, the soil in desert regions consists of sandy desert soil with very low moisture content. Desert soil is composed of finely crushed stones and minerals, making it very difficult to shape in itself, and it also lacks the ability to retain moisture.

[0006] The Middle East, being a desert region, is not suitable for rice cultivation due to a lack of water. To cultivate rice in desert areas, it is advisable to apply a farming method where seedlings are planted in deep furrows that retain water easily, rather than on raised ridges. Additionally, if a drip irrigation system is applied to supply water to individual rice plants rather than flooding the entire furrow, rice cultivation becomes possible even in desert regions.

[0007] However, in the case of desert regions, as mentioned above, shaping is difficult, and due to soil characteristics that make it difficult to retain water, the reality is that forming ridges is not easy with the configuration of conventional ridge forming machines.

[0008] As mentioned above, the present invention provides a furrow forming machine for enabling rice farming by efficiently utilizing a small amount of water for upland rice that can be cultivated in desert areas. Prior art literature

[0021] Hereinafter, preferred embodiments according to the present invention will be described in more detail with reference to the attached drawings.

[0022] Prior to describing the present invention, the following specific structural or functional descriptions are provided merely for the purpose of illustrating embodiments according to the concept of the present invention. Embodiments according to the concept of the present invention may be implemented in various forms and should not be interpreted as being limited to the embodiments described herein.

[0023] In addition, since embodiments according to the concept of the present invention may be subject to various modifications and may take various forms, specific embodiments are illustrated in the drawings and described in detail in this specification. However, this is not intended to limit the embodiments according to the concept of the present invention to specific disclosed forms, and it should be understood that they include all modifications, equivalents, and substitutions that fall within the spirit and scope of the present invention.

[0024] Before explaining the contents of the present invention, agricultural terms related to the present invention are briefly explained.

[0025] A ridge is a raised area created by plowing a field and piling up soil into furrows, while a furrow is a long, narrow indentation between the ridges. Typically, plants are planted and grown on the ridges, while water flows into the furrows. In this regard, the ridges and furrows are sometimes collectively referred to as furrows.

[0026] As described above, in the usual case, plants are planted on ridges, but in the present invention, since the invention is intended for upland rice based on the premise of a desert country with a shortage of water, rice is planted in a furrow where water is retained through drip irrigation by forming grooves in the furrow, so unlike in the usual case, rice is planted in the furrow.

[0027] Of course, since the furrow forming machine according to the present invention forms ridges along with furrows, it should not be interpreted as merely planting crops in the furrows.

[0029] Preferred embodiments of the present invention will be described in more detail below with reference to the drawings.

[0030] FIG. 1 illustrates a furrow forming machine for cultivating field rice according to one embodiment of the present invention installed on a tractor (T), FIG. 2 and FIG. 3 are front and rear perspective views of a furrow forming machine according to one embodiment of the present invention, and FIG. 4 and FIG. 5 are front and rear perspective views of a furrow forming machine according to another embodiment of the present invention.

[0031] FIG. 6 is a front perspective view of the furrow forming part of the present invention, FIG. 7 illustrates the triangular plow of the present invention, and FIG. 8 is a side view of a furrow forming machine according to one embodiment of the present invention.

[0032] Referring to FIGS. 1 to 5, the furrow forming machine (100) according to the present invention can be mounted on the rear of a tractor (T) and used. For example, the furrow forming machine (100) can be detachably coupled to the rear of the tractor (T) to form ridges for cultivating upland rice as the tractor (T) travels, and can simultaneously perform plowing operations to crush the soil for cultivating upland rice and ridge forming operations to form ridges using power drawn from the tractor (T).

[0033] In particular, according to one embodiment of the present invention, the furrow forming machine (100) is characterized by having a groove forming machine (500) that forms a groove to maintain a state in which water is collected by drip irrigation at the planting location of field rice within the furrow. The groove forming machine (500) will be described in detail later.

[0034] Naturally, the machine that provides power to and tows the furrow forming machine (100) is not limited to a tractor, and the furrow forming machine (100) according to the present invention can also be used to form furrows and ridges for crops other than field rice.

[0035] The furrow forming machine (100) according to the present invention is composed of a power shaft, a gearbox, a rotating shaft (30), a side frame (50), a triangular plow (200), a furrow forming part (300), a compaction rotating plate (400), a groove forming machine (500), etc.

[0036] One end of the power shaft may be connected to the tractor (T) and formed to be rotatable by power provided from the tractor (T). For example, the power shaft (10) may be configured such that one end is connected to the rear of the tractor (T), preferably to the power take-off shaft of the tractor (T), and may be implemented to be rotatable in the forward and / or reverse direction by power generated from the tractor (T).

[0037] The gearbox (20) is connected to the other end of the power shaft (10) to transmit power from the tractor (T) downward. For example, the power shaft (10) may be connected to one side of the gearbox (20), and a rotating shaft (30) with a pressing rotating plate (400) attached may be connected to the other side of the gearbox (20) as described above, and thus the gearbox (20) can transmit power provided from the tractor (T) to the rotating shaft (30) connected to the lower part of the gearbox (20).

[0038] A compression plate (400) is mounted on the outer surface of the above-mentioned rotation shaft, and as the rotation of the rotation shaft rotates, the compression plate (400) rotates to compression and form the ridge.

[0039] In addition, a rotary encoder for counting the number of rotations of the rotation shaft (30) is installed inside the rotation shaft (30).

[0041] The triangular plow (200) according to the present invention forms a furrow in the field as the tractor (T) moves.

[0042] As shown in Fig. 7, the triangular plow has a triangular end and is bent in the longitudinal direction to form a curved shape. The width of the triangular plow can be determined according to the width of the furrow to be formed.

[0043] As shown in FIG. 6, the ridge forming section (300) is composed of a pair of first side wall sections (310) facing each other and having their corners in contact, a pair of second side wall sections (320) positioned in contact with the first side wall sections (310) in a state of being inclined obliquely toward the ridge, and a ridge upper forming plate (330) positioned on the upper part of the ridge forming section (300) to evenly smooth the surface of the soil on the upper part of the ridge.

[0044] The above pair of first side wall sections (310) are formed in the shape of a triangular plate, and one side of each of the three line segments is in contact with each other to form a 'V' shape when viewed from above, and the angle of the 'V' shape is adjusted according to the width of the groove to be formed.

[0045] The second side wall (320) is positioned in contact with the first side wall (310) and is positioned in a state of being inclined obliquely toward the ridge, and the second side wall (320) serves to push and gather the soil gathered toward both ridges by the pair of first side walls (310) once more toward the ridge so that it is inclined obliquely.

[0046] Multiple ridge forming sections (300) are arranged in the longitudinal direction, and a ridge upper forming plate (330) is arranged on the upper part of each ridge forming section (300).

[0047] The upper molding plate (330) of the ridge serves to evenly smooth the surface of the soil gathered into the ridge by the ridge molding section (300) as the tractor moves.

[0048] When the shape of the ridge is formed to some extent by the ridge forming section (300) and the ridge upper forming plate (330), the side wall of the ridge is finally pressed by the pressing rotating plate (400) to press the ridge into a solid state, thereby completing the ridge forming.

[0049] The suppression turntable is made up of arc-shaped plates that come into contact with each other, similar to the shape of a pot lid.

[0050] Therefore, when viewed from behind, it has a rhombus shape, and as the compaction plate rotates, the ridge is compacted at an angle corresponding to half of the circumferential angle of the arc-shaped compaction plate to form the ridge.

[0052] A groove forming device (500) that forms grooves in the furrows at regular intervals according to the number of rotations of the suppression rotating plate (400) may be mounted and positioned on the rear side of the suppression rotating plate (400).

[0053] The above-mentioned groove forming device (500) is for forming a groove to retain water by drip irrigation at the planting location of field rice within the furrow.

[0054] That is, in order to form grooves according to the predetermined spacing of the planting positions of the field rice, the groove forming device (500) described above moves up and down in reciprocating motion according to the speed of the tractor (T) and the rotational speed of the rotating shaft (30) to which the compacting plate (400) is attached during the furrow forming operation, thereby forming grooves at regular intervals in the furrow according to the direction of travel of the tractor.

[0055] In addition, the above-mentioned groove forming device (500) is positioned behind the suppression rotating plate (400) according to the installation spacing of the suppression rotating plate (400), and is installed at regular intervals on the connecting bar (70) arranged in the horizontal direction.

[0056] In relation to the up-and-down reciprocating motion of the groove forming machine (500), the connecting bar (70) is connected to the main frame by a linear cylinder, and as the connecting bar (70) moves up and down according to the up-and-down movement of the linear cylinder, a groove is formed in the groove by the groove forming machine (500).
