(Points of interest)
Despite the diversification of food culture, Japan's staple food is still rice, and throughout the country to efficiently produce high-quality rice suitable for each climate from north to south. Modern rice farming continues to be carried out universally, and the results of infrastructure development such as repeated land readjustment projects have come to fruition. The sluice gates and weeding facilities at each site are strictly managed by local water users associations and land improvement districts, and weeding the shores around the irrigation canal and providing systematic and equal water intake and supply. Has been running.

    Agricultural waterways that are cooperated and used by many rice farmers in this way should be properly managed so that clean and sufficient water can be obtained down to the downstream fields, especially during the period from rice planting to the intermediate management period. Even if weeding with care not to drop it into the irrigation channel, such as when weeding for the purpose of securing sunlight in the surrounding paddy rice, controlling pests, reducing chemical spray etc. It is inevitable that some of the weeds that have been cut off will fall into the irrigation water and flow away downstream, and farmers who own rice fields in the downstream will interfere with the rice cultivation environment due to the weeds that have flowed into the fields. Care must be taken to prevent any damage, and weeds must be prevented from being damaged by the weeds clogged in the intake. There circumstances that inevitably spend extra a great effort to remove the work of weeds to be al stream of development of herbicide (herbicidal) techniques have been craving that can clean efficiently canal inexpensive therefor.

(Conventional technology)
Under such circumstances, as a measure to overcome the problem, for example, as proposed in the idea of “garbage removal device” in Japanese Utility Model Laid-Open No. 5-83028, a flat cross-section of the intake channel outlet penetrating the side wall of the irrigation channel is proposed. A plate-shaped member surrounding the three sides is provided, and this plate-shaped member is made of a lightweight and corrosion-resistant plate material in which a plurality of small holes are formed, and a handle is provided on the upper end side. Reduces the amount of garbage flowing into paddy fields, reduces the damage caused by garbage on rice seedlings, allows rice to grow normally, and also features easy handling of the dust remover and long service life From the upstream side to the downstream side along the water channel wall of the irrigation channel where the water supply port is opened, as in the invention, "the device for preventing clogging of the rice field water supply port in the irrigation channel" disclosed in JP-A-9-74931 From the waterway wall It consists of an intrusion protector that is placed away from the next, and a latch that holds the intrusion protector in a removable manner on the channel wall. The intrusion protector has a strip shape and is in contact with the channel wall A wall mounting portion that is attached to the water channel wall via a latch metal in a state, and is gently raised and bent toward the downstream side from the wall mounting portion, and at an appropriate interval from the middle substantially parallel to the water channel wall. Formed in a generally planar crank shape from the cover part that is bent and released toward the downstream side, and prevents intrusion of floating substances such as dust and grass into the water supply port with an intrusion protective body when water is supplied to the paddy field Etc. are occasionally seen.

However, the former “garbage removal device” is designed to be used on the side of the farm, which is the outlet of the intake that penetrates the side wall of the irrigation channel. It is impossible to install it so that it does not flow into the crocodile. It has the disadvantage that it cannot be used to prevent it from flowing downstream, and the latter “clogging prevention device for paddy field water inlets in irrigation canals” invention is a field intake in the irrigation canal. It was installed in the vicinity, and suspended matter such as mowing grass flowing down from the upstream side was guided to the downstream side to prevent it from flowing into the paddy field, and it did not demonstrate the effect of cleaning the water channel .

(Awareness of problems)
As described above, the previously proposed “garbage removal device” device and the “clogging prevention device for paddy field water inlet in irrigation channel” inventions are all installed near the irrigation channel from the irrigation channel to the farm field. It is possible to prevent the inflow of mowed grass and floating substances outside it, and it is possible to realize the cleaning of the entire irrigation water by damming and removing the garbage that tries to flow away from the upstream to the downstream of the irrigation channel. It must be installed separately for each field, and the burden on the economy is large. The degree of product increased, leaving the fatal problem of increasing the risk of suffering disadvantages.

(Object of invention)
Therefore, the present invention is easy to carry, can be easily installed at the necessary place of the irrigation channel, and only cut grass or floating matter outside it flows down from the upstream without disturbing smooth running water. Judging whether it is possible to develop a new irrigation weeding (weeding) technology that enables efficient damming and removal, we started its development and research quickly, trial and error over many years, and many trial productions As a result of repeating the experiment, this time, we finally succeeded in realizing a weeding instrument for a waterway with a novel structure, and in the following, together with an embodiment representing this invention shown in the drawings, its configuration is It will be described in detail.

(Structure of the invention)
As can be clearly understood from the embodiments representing the present invention shown in the drawings, the weeding apparatus for waterways of the present invention basically comprises the following configuration.
In other words, the U-groove upper edge bridging points can be attached and detached at both ends of the support shaft with a length that can be bridged between the upper edges of the U-groove installed for agricultural waterways. A plurality of fork-like arrangements arranged between the fixing mechanisms and within the width of the U-shaped groove water channel side by side with a predetermined interval. The long tooth ridges are connected and integrated at their respective ends with the lower frame for regulating the horizontal spacing, and the arrangement from the support shaft to the lower frame is determined according to the support shafts at both upper edges of the U-shaped grooves. A length that restricts the arrangement so that it can be placed obliquely between the rod-hanging part and the bottom of the U-shaped groove where the upstream side is offset from the side, and the shape of each side surface is concave toward the upstream side. Now, the weeding frame formed in the shape can be rotated around the axis of the spindle A waterway for herbicidal instrument to subject matter the configuration was made incorporating.

    The waterway weeding device having this basic structure is shown as a more concrete one. A support rod having a length that can be bridged between both upper edges of U-shaped grooves installed for agricultural waterways and the like. On the other hand, at both ends, a fixing mechanism for detachably fixing the U-shaped groove upper edge bridging portion is incorporated, and between the fixing mechanisms and within the U-shaped groove water channel width. In the part, a base frame of a plurality of long tooth hooks that are mounted in a fork-like arrangement at a predetermined interval is mounted side by side within the range of the top frame, and a base frame is connected to each of the long teeth. The leading ends of the long tooth ridges are connected and integrated with a lower frame for regulating the side-by-side spacing, and the arrangement from the upper frame of the support shaft to the lower frame is determined according to the support at both upper edges of the U-shaped groove. It can be placed diagonally between the shaft rod spanning part and the bottom of the U-shaped groove where the upstream side is offset In addition, a weeding frame formed in such a length and shape that each side shape is concave toward the upstream side is incorporated so as to be rotatable around the axis of the support shaft. It becomes the weeding implement for waterways which consists of the composition which consists of.

    As described above, according to the weeding apparatus for waterways of the present invention, the support shaft bar having a length that can be bridged between both upper end edges of the U-shaped groove installed for agricultural waterways is provided. A plurality of long tooth ridges that are arranged side by side within a range of the width of the water channel width and are arranged at predetermined intervals are connected and integrated with respective lower side frames for regulating the interval between the respective ends, When mowing work is done on the upstream side, the water that has flowed down in the irrigation channel can be easily and detachably installed at a midway point where the downstream side of the agricultural waterway is mowing. It can be passed smoothly and can be effectively cleaned including only solid materials such as mowing grass and other trash, and until now, it is possible to prevent the cutting grass from flowing into the paddy field. It has been considered very difficult, but this is definitely prevented, Inclination of the irrigation failure and rice by the influx into the field of grass, and, to demonstrate the effect that it becomes possible to entirely eliminate the adverse effects, such as the occurrence of pests due to it.

    After the irrigation channel has been cleaned, it can be easily removed and brought back to the vehicle for storage, and if it is always on-board during the inspection of paddy rice or farming, we found the flow of hay in the irrigation channel. Sometimes it has an excellent feature that it can be installed immediately, and it is not necessary to install a large weeder that requires expensive capital investment. By installing one or more of them in tandem in the irrigation channel upstream from the paddy field that is the target of irrigation, weeding and weeding can be carried out more efficiently. Therefore, before we start mowing around the irrigation channel or in the field, weeding the downstream of the irrigation channel in advance If so as to install the tool, erosion of downstream I water is dammed immediately mowed grass, that it becomes possible to prevent the pollution phenomenon, the effect can be expected than ever before.

    In addition, it is assumed that a fixing mechanism for temporarily fixing each of the U-shaped groove upper edge bridging points is incorporated at both ends of the support shaft, and the weeding device for the waterway is unexpectedly moved by flowing water pressure, A plurality of long tooth ridges that can be prevented from being washed away, and the arrangement state from the support shaft to the lower frame of the plurality of long tooth ridges, the support rod spanning points on both upper edges of the U-shaped groove, Then, it was regulated so that it could be placed diagonally between the bottom of the U-shaped groove where the upstream side was offset, and the flowing water pressure received by each long tooth ridge was adjusted to the upper edge of the U-shaped groove and the U-shaped It can be distributed and transmitted to the bottom of the groove to obtain sufficient installation strength, and each side shape of the long tooth ridge is formed in a length and shape that is concave toward the upstream side. The weeding frame is incorporated so that it can be freely rotated around the axis of the support shaft. Grass that has flowed down can flexibly take it to Shiwau flowing water pressure generated when the dammed, can be realized and durability strength was Xiu, a high backlog effect of grass clippings.

    Further, the base end of the plurality of long tooth ridges is mounted on the weeding frame body by mounting an upper frame that is rotatable with respect to the support shaft, and arranged in a fork-like arrangement at a predetermined interval side by side within the upper frame. Connected to each other, and the tip of each long toothed hook is connected with the lower frame for side-by-side spacing regulation, and it is integrated, because of the connection to the spindle rod through the upper frame of each long toothed base Besides, it is possible to remarkably increase the strength of the connecting portion of the weeding frame body that is rotatable with respect to the support shaft rod, and the upper frame and the lower frame of the weeding frame body are respectively parallel to the support shaft rod and one end. Provided with a weeding width adjusting mechanism comprising a guide rail portion arranged on the hook and a slider portion which is movable forward and backward along the guide rail portion and the other end of the support shaft is arranged on the hook. If the distance between the pair of long tooth ridges can be changed freely, the guidance of the weed width adjustment mechanism The slider portion is slid forward and backward with respect to the rail portion, and the width dimension of the weeding frame body is freely adjusted according to the channel width of the irrigation channel U-shaped groove. On the other hand, it has a great feature that it can be properly installed without gaps that allow the grass to pass easily.

    Furthermore, if either the support shaft or the upper frame of the weeding frame is equipped with a hanging hook near its center of gravity, it can be stored on a wall inside the warehouse, etc. It is possible to hang it on the truck bed, torii, etc. so that the loading space is not lost, and the weeding equipment for the waterway must be kept and carried on a daily basis in preparation for water management during the irrigation period. In some cases, it can be installed immediately in agricultural waterways at any time. On the other hand, a fixing mechanism is provided at each end of the support shaft so that both ends of the support shaft are bridged between both upper edges of the U-shaped groove. Securely and temporarily fixed, it is possible to reliably prevent the change in the posture of the weeding equipment for waterways and the occurrence of runoff, and in particular, the downwardly sharpened pile part can be rotated with respect to the support shaft or can not rotate. With one of the possible fixing After determining the installation position and the installation posture in the U-shaped groove, it is integrated and formed so that it can be stuck and fixed to the ground surface where both outer edges of the U-shaped groove of the agricultural waterway become traps. Immediately, the sharp tip of each pile part can be easily and quickly temporarily fixed by driving it into the ground, making it possible to realize more efficient and reliable installation work. When integrated with either one of the rods so that they can be rotated or fixed non-rotatably, the clamps are clamped between the upper edges of the U-shaped grooves, making them more reliable and strong. The excellent effect that it can be temporarily fixed to is obtained.

    On the other hand, a connecting cylinder for mounting a rotating operation rod is vertically installed and integrated at a proper position of the weeding frame body, and the connecting cylinder itself or the weeding frame body integrated with the connecting cylinder is the support shaft. When the situation is such that a lot of mowing grass is dammed to the weeding frame that is installed obliquely in the water of the U-shaped groove, Mount the tip of a separately prepared pivoting rod, the pivot rod as a fulcrum, the free end of the pivoting rod as a force point, and the weeding frame lower frame as a working point. Even when there is no moving rod, it is very difficult to pull up the grass that has been dammed up in the water flow. Move the herbage frame up or down from the bottom of the groove to the surface of the water and change the posture to near the water surface or above the water surface, Because it can be exposed to the surface, it is extremely practical to improve the efficiency and safety of the troublesome grass (garbage) collection work that flows down the waterway, and to greatly reduce the labor burden. The effect will be effective.

In implementing the present invention having the configuration as described above, the best or desirable mode will be described.
