Description

[Technical Field]

[0001] The present invention relates to a cultivation tool for cultivating agricultural crops. [Background technology]

[0002] Conventionally, when cultivating agricultural crops on the ground in a farm field, workers have had to sit or bend over to work, which places a strain on the workers.

[0003] In addition, by using a box surrounded by side walls and filling the box with soil to cultivate plants, the height of the top surface of the soil inside the box can be raised above the ground, reducing the burden on the worker. However, the presence of the side walls restricts the position of the worker's toes, forcing them to work from a position away from the box, which can impair workability.

DETAILED DESCRIPTION OF THE INVENTION

[0009] An embodiment of the present invention will now be described with reference to the drawings.

[0010] 1 and 2 show a cultivation tool 10. The cultivation tool 10 is assembled and placed on the ground 11 of soil in a field, for example.

[0011] The cultivation tool 10 includes a frame 13 that contains soil 12, such as field soil or horticultural soil, for cultivating agricultural crops. The frame 13 is rectangular in plan view, with a longitudinal dimension of approximately 4700 mm, a transverse dimension (width) intersecting the longitudinal dimension of approximately 800 mm, and a height from the ground 11 of approximately 1000 mm, for example.

[0012] The top and bottom surfaces are open inside the frame body 13, forming a storage space 14 for storing soil 12. There is no bottom plate on the bottom surface of the storage space 14, and the bottom surface of the storage space 14 is the ground surface 11. Therefore, the soil 12 filled into the storage space 14 of the frame body 13 is piled up on the ground surface 11.

[0013] The frame 13 has a plurality of support posts 15 erected on the ground 11 and side walls 16 arranged between these support posts 15, and is configured so that the plurality of side walls 16 surround the periphery of the storage space 14. The support posts 15 and side walls 16 are made of wood, for example, but may also be made of resin or metal.

[0014] The support posts 15 are erected on the ground 11 by burying their lower sides in the ground 11. The support posts 15 have corner posts (first posts) 20 arranged at the four corners and multiple connecting posts (second posts) 21 arranged in the middle of the long sides. The corner posts 20 have a substantially L-shaped cross section in the horizontal direction, and the ends of the long side walls 16 and the short side walls 16 are arranged inside the corner posts 20 in a combined manner. The connecting posts 21 have a substantially H-shaped cross section in the horizontal direction, and are assembled by inserting the ends of the side walls 16 from above into connecting grooves 22 formed on both sides.

[0015] The side walls 16 have long side walls 23 disposed on the long sides of the frame body 13 and short side walls 24 disposed on the short sides of the frame body 13 .

[0016] 2 and 3, the long side wall 23 includes a lower side wall 23L at the bottom, an intermediate side wall 23M stacked on the lower side wall 23L, and an uppermost upper side wall 23U stacked on the intermediate side wall 23M. Fitting grooves 25 are provided over the entire longitudinal area on the upper surfaces of the lower side wall 23L and the intermediate side wall 23M, and fitting protrusions 26 are provided over the entire longitudinal area on the lower surfaces of the intermediate side wall 23M and the upper side wall 23U so as to be fittable into the fitting grooves 25. No fitting grooves 25 are provided on the upper surface of the upper side wall 23U.

[0017] 4, the short-side side walls 24 include a lower side wall 24L at the bottom, an intermediate side wall 24M stacked on the lower side wall 24L, and an uppermost upper side wall 24U stacked on the intermediate side wall 24M. Fitting grooves 25 are provided over the entire longitudinal length on the upper surfaces of the lower side wall 24L and the intermediate side wall 24M, and fitting protrusions 26 are provided over the entire longitudinal length on the lower surfaces of the intermediate side wall 24M and the upper side wall 24U so as to be fittable into the fitting grooves 25. No fitting grooves 25 are provided on the upper surface of the upper side wall 24U.

[0018] 2 to 4, buried portions 27 to be buried in the ground 11 are provided on the lower sides of the side walls 16, i.e., on the lower sides of the lower side walls 23L, 24L. The buried portions 27 may be buried in the ground 11 by pressing the base side walls from above after being placed on the ground, or by piling up soil 12 on the ground 11 after being placed on the ground 11. Alternatively, the buried portions 27 may simply be placed on the ground 11.

[0019] The height of the cultivation tool 10 from the ground 11 can be adjusted depending on the length of the supports 20, 21 and the number of stacked intermediate side walls 23M, 24M.

[0020] As shown in FIGS. 2 and 3 , an opening 28 is provided at the lower side of the long side wall 23, which is the side wall 16 located on the long side of the frame body 13. The opening 28 is provided above the buried portion 27 of the lower side wall 23L. The vertical height of the opening 28 is, for example, approximately 150 mm, allowing the toes of a shoeed worker to be inserted therein, and the width along the longitudinal direction of the lower side wall 23L is approximately 1200 mm, which is smaller than the longitudinal dimension of the lower side wall 23L. The opening 28 is located in a region more inward than the periphery of the lower side wall 23L. The lower side of the opening 28 is preferably at approximately the same height as the ground 11, allowing the toes of a worker to insert therein without getting caught in the buried portion 27.

[0021] The inside of the opening 28 in the lower side wall 23L is covered with a retaining wall 30, which prevents the soil 12 contained inside the frame body 13 from filling up the opening 28 or escaping through the opening 28 to the outside. The retaining wall 30 is made of, for example, resin, metal, or wood, and has a substantially semicircular cross section in the vertical direction, with its upper and lower ends fixed to the inside of the lower side wall 23L at the upper and lower edges of the opening 28 by fixing members 31, such as screws. The longitudinal dimension of the retaining wall 30 is the same as or longer than the longitudinal dimension of the opening 28. The longitudinal end faces of the retaining wall 30 may be open, but are preferably closed with blocking members.

[0022] The retaining wall 30 protrudes further into the storage space 14 inside the frame body 13 than the opening 28, and the opening 28 and the inside of the retaining wall 30 facing the opening 28 form a recess 32 on the lower side of the side wall 16 into which the worker's toes can fit.

[0023] When installing the cultivation tool 10, first, the lower portions of the supports 20, 21 are buried in the ground 11, and then the supports 20, 21 are erected on the ground 11.

[0024] Next, the lower side wall 23L of the long side wall 23 is inserted from above between the supports 20, 21 and between the supports 21, 21, and the buried portion 27 of the lower side wall 23L is buried in the ground 11. Similarly, the lower side wall 24L of the short side wall 24 is inserted from above between the corner supports 20, 20, and the buried portion 27 of the lower side wall 24L is buried in the ground 11.

[0025] Furthermore, the middle side walls 23M, 24M and the upper side walls 23U, 24U are assembled in this order from above onto the lower side walls 23L, 24L to form the frame body 13.

[0026] The storage space 14 of the frame 13 is filled with soil 12 for cultivation. The soil 12 is piled up on the ground 11 because the bottom of the frame 13 is open.

[0027] Then, with respect to the installed cultivation tool 10, the worker moves through the working area 40 along the longitudinal direction of the cultivation tool 10 on both sides of the shorter side of the cultivation tool 10, and performs work to cultivate crops in the soil 12 inside the cultivation tool 10.

[0028] At this time, the height of the top surface of the soil 12 in the cultivation tool 10 is set at a position higher than the ground 11, so the worker can work while standing without sitting or bending over greatly, thereby reducing the burden on the worker.

[0029] When a worker works on the cultivation tool 10 from the work area 40, the worker can insert his / her toes into the recesses 32, allowing the worker to approach the cultivation tool 10 and easily perform work.

[0030] In this way, by using the cultivation tool 10, the burden on the worker can be reduced and workability can be improved.

[0031] The recess 32 is formed by an opening 28 opened in the side wall 16 and a soil retaining part 30 that protrudes inside the frame body 13 and covers the opening 28, and while allowing a worker to insert his or her feet into the recess 32, it is possible to prevent the opening 28 from being filled with soil 12 inside the frame body 13 or the soil 12 from leaking out through the opening 28.

[0032] The side wall 16 is provided at its lowest part with an embedded portion 27 that is embedded in the ground 11, so that the side wall 16 can be firmly installed on the ground 11.

[0033] A recess 32 is provided on the upper side of the buried portion 27 of the side wall 16, and the lower side of the recess 32 is made approximately the same height as the ground 11, so that the worker can insert his / her feet into the opening 28 without getting caught on the buried portion 27.

[0034] Because the retaining portion 30 is formed in a semicircular ring shape in cross section that protrudes toward the inside of the frame body 13, it is strong and can support the pressure of the soil 12 inside the frame body 13 while allowing the worker's toes to be inserted into the recess 32.Furthermore, when the worker's toes are inserted into the recess 32, the insertion is gradually restricted along the inner arc of the retaining portion 30, so the impact when the toes hit and stop against the retaining portion 30 can be reduced compared to when the retaining portion 30 is a vertical wall surface.

[0035] The height of the cultivation tool 10 from the ground 11 can be adjusted depending on the length of the supports 20, 21 and the number of stacked side walls 16.

[0036] The frame body 13 of the cultivation device 10 has a rectangular shape when viewed from above, and a recess 32 is provided in the long side wall 23, which is the side wall 16 located on the long side, so that the worker can work from one side of the frame body 13 in the short direction to the other side, improving workability.

[0037] The short side wall 24 of the frame 13 may also be provided with a recess 32 .

[0038] Although the embodiment of the present invention and its modified examples have been described above, various combinations of configurations, partial omissions, substitutions and modifications are also possible. [Explanation of symbols]
