2. Description of the Related Art In the current situation of rice farming in Japan, the introduction of market principles into rice distribution along with the liberalization of rice sales has forced the reduction of rice sales prices, and the production of high-quality rice adds value. Together with the need to increase work efficiency and maintain strong competitiveness, and to deal with the successor problem as a special environment industry that is often shunned by comparison with other industrial fields. In addition to the circumstances, the shift to part-time jobs to stabilize the management base has progressed, and the time and labor devoted to agricultural work has started to be squeezed, and various severe factors have forced us to switch to major mechanization. It is falling.

[0003] In particular, for part-time farmers, efficient farming is required in a short time. For example, when looking at rice harvesting in the harvest season, a wide field is harvested with a combine or the like. Many farmers have to harvest by themselves using a machine, and in order to improve work efficiency, if the field is well-organized, the outer periphery of the field is spirally wound in one direction and cut toward the center. It is devised to reduce the number of turns and the angle of the turn, or, if it is an irregular rice field, etc., in order to facilitate the handling of the combine, first, after cutting the outer peripheral side of the rice field around 2-3 turns, It is recommended to perform a middle splitting operation in which the area near the center of the rice field is cut longitudinally, cut along the long side direction from the vicinity of the center, and successively move to both sides to cut the field.

[0004] Even in the case of mechanized rice harvesting for improving work efficiency, large-scale mechanical harvesting can be performed at the place where the combine is first stepped on, or at a portion which is slightly left in the four corners of the rice field in the turning process. In most cases, only those places have to rely on hand-cutting, and for those who have become accustomed to machine-cutting, even the slightest part of rice cutting is not only very troublesome. In addition to delaying the cutting time shortened by mechanical cutting, it is necessary to move between the four corners of a large rice field, especially when the rice harvesting work has to be done by one person for some reason. In addition to wasting wasted time, while getting off and on the machine, mowing the part with a traditional scythe will result in a considerable increase in worker fatigue. Would strengthen the burden of the work itself mosquitoes had also become a cause.

[0005] The inventor of the present application, as one of those who has been engaged in agricultural work for many years, has not been able to wipe out a small amount of the hand-cutting work which is still left in the recent rice-cutting work with such a machine. After struggling with it, farmers thought of using the weed mower that they always had, and could easily and quickly cut even small-area rice, and were lightweight, easy to carry and efficient. We have started developing and researching tools for attaching brush cutters that enable work, and have repeated many experiments with trial and error over a long period of time. We also completed a rice harvesting frame with a new structure that can be attached and fixed, and succeeded in putting it into practical use. In the following, the configuration will be described in detail together with an embodiment representative of the present invention shown in the drawings.

It is a rice-harvesting frame for mounting a brush cutter, which is configured to be able to adjust the movement in the direction.

The holding frame main body functions to collectively hold the rice harvested by the bush cutter and surrounds the outer side of the rotating blade that is not used for cutting, thereby preventing unnecessary contact of the rotating blade with others. And has a receiving frame portion holding a predetermined amount of the cut rice, and a protective frame portion arranged outside the rotary blade that is not used for cutting and surrounding in an arc shape. In the manner described above, for example, after bending and forming a plurality of metal rods, as in an example described later,
It may be formed in the shape of a frame or a basket by welding, or may be formed by welding a plurality of narrow and narrow metal plates having a small width as described above, and furthermore, a synthetic resin However, there is no problem even if a material molded into an equivalent shape is adopted.

The fixing ring has a function of attaching and fixing the holding frame main body to the tip end side of the operation handle rod of the brush cutter, and furthermore, has an attachment angle of the holding frame main body to the operation handle rod, and / or ,
The fixing ring is provided with an angle adjusting screw and an advancing / retracting adjusting screw, and a nut is screwed onto each screw. With the angle adjusting screw, the mounting angle is fixed to an appropriate position on the back of the entanglement preventing wall so that the mounting angle can be adjusted, and the mounting position on the operating handlebar is adjusted by the advance / retreat adjusting screw in the axial direction of the handlebar. Either fixed, or provided with an angle adjusting screw and a nut screwed on it, so that only the mounting angle to the operating handle can be adjusted, or only the forward / backward adjusting screw and the nut screwed on this Is provided so that only the axial mounting position of the operation handle rod can be adjusted.

The above-mentioned adjusting function is achieved, for example, by a tightening ring having a receiving piece part in which the fixing ring is positioned on the side of the entanglement preventing wall, and a mating piece part which sandwiches the operating handle rod in the receiving piece part. It is configured to be tightened and loosened by screwing the tightening ring portion, or to a structure such as a short metal tube divided into two as in the embodiment described later. It is also possible to connect the lower end piece so as to be openable and closable in a hinge shape, form the upper end piece in a parallel shape, insert an advance / retreat adjusting screw, screw a nut to this, and tighten it. In addition, in addition to forming the lower end pieces in parallel to each other and realizing a structure provided with an angle adjusting screw penetrating these, the base end of the angle adjusting screw is coupled to the receiving piece, It can be realized as a single piece as if protruding To.

The protective frame prevents unnecessary contact of the rotary blade with other objects on the peripheral side of the rotary blade during rice harvesting, and has a function of preventing damage to the contacted object and spilling of the rotary blade. It also fulfills the function of ensuring safety at the same time, for example, it may be composed of a curved metal rod arranged in an arc shape on the centrifugal side of the rotary blade, and may be a vertical split made of synthetic resin. It is also possible to adopt a dish-like structure having a predetermined rigidity such as a cover, and to be attached to the receiving frame side or the roll-in preventing wall with bolts and nuts.

The receiving frame portion has a function of temporarily holding a predetermined amount of rice harvested by the rotary blade. The receiving frame portion is substantially concentric with the rotation axis of the rotary blade on the opening side of the protective frame portion. To be formed in a gutter shape having a predetermined length, for example, a metal bar is formed by bending, or a gutter-shaped curved plate made of a lightweight material such as synthetic resin is used. Since the receiving frame portion is a relatively large part for holding rice, it is desirable that the receiving frame portion be made of a lightweight material as much as possible.

The entanglement preventing wall portion is located on the opening side of the protective frame portion and functions to block the lower end portion of the cut rice and prevent it from being entangled in the rotary blade. It is also possible to form a flat plate arranged on the wraparound side of the blade, or to form a raked rice bottom scooping surface that is inclined so as to scoop up the lower end of the rice wrapping around with the rotating blade. In addition, as in the embodiments described below, the entanglement preventing wall portion is formed in a vertical or inclined wall shape with a slight gap formed on the upper side of the rotary blade. May be detached from the rotary blade, guided upward along the inclined surface, and temporarily held.

The angle adjusting screw and the nut screwed thereto fix the holding frame main body to a desired angle with respect to the operation handle rod by tightening, and perform the function of freely adjusting the angle by loosening. For example, an angle adjusting screw is fixedly and erected integrally with the fixing ring, and the angle adjusting screw is inserted through an insertion hole formed in the wrap prevention wall of the holding frame main body, or in the vicinity thereof, By screwing the nut, it is possible to perform the above function,
An angle adjusting screw is inserted into an insertion hole formed in each of the fixing ring and the holding frame main body in the vicinity of the entanglement preventing wall, and a nut is screwed into the angle adjusting screw to perform the above-described function. It is also possible. Furthermore, it is also possible to adopt a configuration in which an angle adjusting screw is projected and fixed to the entanglement preventing wall portion, and a fixing ring is attached thereto so that the angle can be adjusted, and is fastened and fixed with a nut.

The forward / backward adjusting screw is attached to and fixed to the operating handle rod together with the nut to be screwed thereto and the fixing ring fixed to the holding frame main body. This function serves to adjust the position of the holding frame body in the axial direction of the holding ring. For example, each end piece of the separated portion of the fixed ring is bent in parallel, and these end pieces are adjusted to advance and retreat. A screw that is inserted and a nut is screwed to its tip, or two or more than three or more advance / retreat adjusting screws are screwed to increase the tightening force. In addition to the above, it is also possible to use a thumb screw to make a tool unnecessary.

It is also possible to provide a reinforcing structure which is not easily deformed even by tightening with an angle adjusting screw, at the joint between the fixing ring and the entanglement preventing wall. In addition to the thick cylindrical annular seat shown in the embodiment described later, the fixing ring is provided on the entanglement preventing wall portion through which the screw is inserted. So that it can be slid around, and to prevent the displacement of the rice harvesting frame with respect to the bush cutter,
It is also possible to provide a mating uneven portion or a key structure formed at predetermined angles.

It is to be noted that whether the gutter-shaped opening side of the receiving frame portion or the opening portion of the protection frame portion formed correspondingly is formed on the left or right side is particularly limited. Rather, for example, by providing an insertion hole for attaching a fixing ring to each of the front and rear (distal side) ends of the entanglement preventing wall, a rice cutting frame that can be cut in any direction is provided. It is also possible. Further, depending on the shape of the fixed ring, there is a possibility that the operation handle rod may interfere with the entanglement preventing wall portion formed in a flat shape at the time of attachment and may not be attached. In order to avoid the problem, the entrapment preventing wall portion may be bent or cut into a concave shape over a predetermined range along the operation handle rod to form a shape that does not cause interference between the entrainment preventing wall portion and the operation handle rod. It is possible. Less than,
In order that the mower-mounting rice-harvesting frame of the present invention can be more clearly understood, some embodiments having representative configurations will be specifically described with reference to the accompanying drawings.
