  However, in the case of these conventional structures, the crops W such as paddy rice plants are planted at a fixed size between the streak B and the stock M by a riding type rice planting machine such as four-row planting, six-row planting, and eight-row planting, and After planting the seedlings, about three times, a plurality of middle-plowing weeding mechanisms are used to carry out the middle-plowing weeding by suppressing the weeds by advancing the intervals between the crops. In this weeding operation, for example, as shown in FIG. , When weeding the 6-row planted row with a 4-row medium-plowing weeder, it is necessary to strictly align the weeded row B and the non-weeded row B in order to prevent seedling damage In addition, when using a riding type rice transplanter, etc., the crop may be bent in a meandering manner depending on the situation of the paddy field and the driving situation, so that the crop is damaged or the weeding work efficiency is reduced, Prepare a weeding machine with the same number of lines as the number of rice transplanters. It has the disadvantage that there is that that must be.

  The present invention aims to solve such inconveniences, and among the present inventions, the invention according to claim 1 is characterized in that a plurality of medium-plowing weeding mechanisms are arranged side by side with respect to the traveling direction on the traveling frame. The middle plowing weeder is provided with a swinging swinging mechanism that swings to the left and right according to the traveling resistance of the traveling frame body.

  According to a second aspect of the present invention, as the swing swing mechanism, a swing arm is provided on the travel frame body so as to be swingable to the left and right by a fulcrum longitudinal axis, and the middle tiller is disposed at a rear portion in the traveling direction of the swing arm. A weeding mechanism is provided, and the invention according to claim 3 is characterized in that the middle-cultivated weeding mechanism comprises an inter-strain rotor capable of weeding a weed existing between crop plants. Is.

  As described above, in the invention according to claim 1, when the present invention is advanced through the traveling frame, a plurality of middle-plowing weeding mechanisms will simultaneously plow a plurality of weeds existing between crop stocks, At this time, each of the plurality of medium-plowing weeding mechanisms independently swings and swings to the left and right according to the resistance to the ground, crops, and water as the traveling frame progresses. Weeding work can prevent damage caused by crop collisions even when the alignment between the existing and non-weeded lines is not strict or when the crops are bent in a meandering manner. Efficiency can be improved.

  According to a second aspect of the present invention, as the swing swing mechanism, a swing arm is provided on the travel frame body so as to swing freely in the left and right directions along the fulcrum longitudinal axis, and the swing arm is moved rearward in the traveling direction. Since the middle plowing weed mechanism is provided at the position, the swing arm swings left and right around the vertical axis of the fulcrum, and swings and swings. According to the invention described in claim 3, the middle plowing and weeding mechanism is composed of an inter-rotor rotor capable of weeding the weeds existing between the crops. The weeds existing between the strains can be satisfactorily plowed without damaging the seedlings.

  1 to 10 show an embodiment of the present invention. FIGS. 1 to 9 show a first embodiment, and FIG. 10 shows a second embodiment.

  In the first embodiment shown in FIGS. 1 to 9, reference numeral 1 denotes a traveling frame. In this case, a grip handle 2 is provided at the rear, an engine 3 is mounted, and wheels 5 and 5 are provided at both ends of the axle 4. Thus, it is configured as a walking structure that grips the grip handle 2 and proceeds with the engine 3 as a drive source.

  6 is a middle plowing weeding mechanism, and in this case, it has a four-row weeding structure provided with four middle plowing weeding mechanisms 6. Each of these four middle plowing weeding mechanisms 6 exists in the inter-strain M of the crop W. A pair of inter-strain rotors 7 capable of weeding the weeds F are provided.

  8 is a swinging swinging mechanism, which has a structure in which the middle plowing and weeding mechanism 6 is swingable to the left and right by the resistance to the ground, crops, and water with the traveling frame 1 traveling, In this case, as the swinging and swinging mechanism 8, a swinging arm 9 is provided on the travel frame 1 so as to swing freely to the left and right by a fulcrum longitudinal axis 10. Is provided.

  In this case, the four sets of middle plowing and weeding mechanisms 6 are provided in two rows in the front row of the traveling frame 1, two rows in the rear row, and a total of four rows in a staggered manner. 6a is provided at four positions in the arrangement, the fulcrum vertical axis 10 is provided vertically at the intermediate position of the restriction frame 6a, and the front part of the swing arm 9 in the advancing direction is pivotally attached to each fulcrum vertical axis 10, A pair of inter-strain rotors 7 are provided at the rear part in the traveling direction of 9.

  In this case, the pair of inter-strain rotors 7 are provided with a pair of support rods 7a and 7a on each swing arm 9, and are opposed to each other with the crop W as a boundary, and support pieces 7b and 7a are disposed on the support rods 7a and 7a. The vertical axes 7c and 7c are arranged in a vertical direction with a tilt angle of 15 degrees in this case, and the vertical axes 7c and 7c are vertically arranged with respect to the horizontal with respect to the crop W through 7b. A rotor material 7d, 7d is provided on 7c so as to be pivotable, and a plurality of blade members 7e, 7e are projected in a radial manner on the rotor material 7d, 7d.
