  Here, a specific configuration of the second post-work body 12b will be described with reference to FIGS. 5 (a) and 5 (b).

  As described above, the second rear work body 12b is the same as the third rear work body 12c, and includes a rear support arm 23, a rear chisel 24, a rear inversion plate 25, a pair of left and right rear wings 26, and the like. Yes.

  The rear support arm 23 is formed in a substantially square shape that is curved so that the lower end side is directed forward. The rear chisel 24 has a substantially triangular shape (asymmetrical shape) in plan view, and is formed in a flat plate shape. The rear chisel 24 is gradually inclined downward toward the front, and is directed to a predetermined long distance A side (side where the soil is reversed by the rear reverse plate 25) so as to correspond to the rear reverse plate 25. The slope is gradually descending.

  The rear inversion plate 25 has a substantially triangular cutout portion 10, and is formed in a curved plate shape that is bent so that the upper end side faces the left side that is the side that inverts the soil. The rear inversion plate 25 is gradually inclined downward so that the upper surface on the lower end side of the rear inversion plate 25 and the upper surface of the rear chisel 24 are flush with each other.

  Each of the left and right rear wings 26 has a substantially rectangular shape with a narrower width toward the tip in plan view, and is formed in a flat plate shape. The rear end of each rear wing 26 is attached to the lower end of the rear support arm 23, and protrudes from the lower end of the rear support arm 23 toward the rear oblique side. Each rear wing 26 is gradually inclined downward from the proximal end portion toward the distal end portion. That is, each rear wing 26 is gradually deeper toward the tip. As a result, the front end (lower end) of each rear wing 26 is positioned below the front end (lower end) of the rear chisel 24.

  The left and right rear wings 26 have different lengths, and the left and right rear wings 26 located on a predetermined short distance B side (the side where the soil is not reversed by the rear reversing plate 25) of the rear wings 26 when viewed from the front. The length in the direction is shorter than the length in the left-right direction of the rear wing 26 located on the predetermined long distance A side (the side on which the soil is reversed by the rear reversing plate 25) of both rear wings 26 when viewed from the front. It has become.

  Although the specific configurations of the rear working bodies 12b and 12c have been described, the front working bodies 11a and 11b and the rear working bodies 12b and 12c are symmetrically configured as described above. Description of the specific configuration of is omitted. The front work bodies 11a, 11b, and 11c and the rear work bodies 12a, 12b, and 12c are alternately arranged in the left-right direction when viewed from the front, and the work section 5 is configured by these six work bodies. Further, as is apparent from FIG. 1, the front end portion of the front wing 16 and the front end portion of the rear wing 26 that are adjacent to each other in a front view overlap each other.

  On the other hand, as shown in FIG. 3, the agricultural working machine 1 includes a pressure-reducing wheel 31 that is attached to the rear ends of both frame plate portions 4 of the body 2 and performs pressure-reducing work behind the rear work bodies 12 a, 12 b, 12 c. I have.

  The pressure-reducing wheel 31 has an attachment frame 30 that is detachably attached to the rear ends of both frame plate portions 4 of the body 2.

A rotating body 32 is rotatably attached to the lower end portion of the support plate portion 30a of the mounting frame 30. Between the left and right rotating bodies 32, a plurality of pressure reducing bars 33 that are longitudinal in the left-right direction are installed.

  Next, the operation and the like of the farm work machine 1 will be described.

  When plowing work (rough raising work) using the farm work machine 1, after connecting the tractor connection part 3 of the machine body 2 to the rear part of the tractor (not shown), the farm work machine 1 is operated by operating the three-point link hitch part of the tractor. The whole is lowered, and the lower ends of the working bodies 11a, 11b, 11c, 12a, 12b, and 12c are inserted into the soil of the field.

  Then, when the farm work machine 1 is moved forward by the forward traveling of the tractor, the front work bodies 11a, 11b, and 11c cut and lift the soil of the farm field, and are reversed and released to the right side, and the rear work bodies 12a, 12b, 12c cuts and lifts the soil in the field and flips it to the left.

  As a result, as shown in FIG. 1, the cutting soil from the front chisel 14 is guided by the front reversing plate 15 so as to be reversed in the direction of the arrow shown in the figure, and from the rear chisel 24. The soil is reversed and released in the direction of the arrow shown in the figure by being guided by the rear inversion plate 25. Then, the reversing cutting soil is pressed down by the pressing wheel 31 that rotates while moving forward.

  And according to such a farming machine 1, the predetermined long distance A which is the distance between the front surface of the front reversing plate 15 and the front surface of the rear reversing plate 25 which are spaced apart from each other in the front view is the same in the front view. It is longer than a predetermined short distance B, which is the distance between the rear surface of the front reversing plate 15 and the rear surface of the rear reversing plate 25 that face each other. As a result, the front surface of the front reversing plate 15 and the rear reversing plate 25 Since the space part a between the front surface is wider than the space part b between the rear surface of the front reversing plate 15 and the rear surface of the rear reversing plate 25, the reversibility of the cutting soil is improved and proper tilling work is performed. Can do.

  Further, the length in the left-right direction of the front wing 16 located on the predetermined short distance B side in the forward view is shorter than the length in the left-right direction of the front wing 16 located on the predetermined long distance A side. Since the rear side wing 26 located on the short distance B side has a length dimension in the left-right direction shorter than that of the rear wing 26 located on the predetermined long distance A side, The useless portion where the front wing 16 and the rear wing 26 overlap with each other can be reduced, and the weight can be reduced and the material cost can be reduced.

  Furthermore, the tip of the inclined front wing 16 is positioned below the tip of the inclined front chisel 14, and the tip of the inclined rear wing 26 is lower than the tip of the inclined rear chisel 24. Therefore, the tip side of the wings 16, 26 and the tip part of the chisel 14, 24 are the same depth when the tip side of the wings 16, 26 bends upward due to the resistance of the soil. As a result, the bottom surface of the tillage can be flattened.

  In addition, since both the front chisel 14 and the rear chisel 24 are inclined downward toward the soil reversal side, which is the predetermined long distance A side, the reversibility of the soil is further improved, and more appropriate tillage work is performed. it can.

  In the above embodiment, the configuration including the three front work bodies 11a, 11b, and 11c and the three rear work bodies 12a, 12b, and 12c has been described. However, at least two front work bodies 11a, 11b and at least Any configuration including two rear working bodies 12a and 12b may be used. For example, although not shown, a configuration including four or more front working bodies and four or more rear working bodies may be used.

  Further, for example, a synthetic resin plate to which soil is difficult to adhere may be detachably attached to the front surfaces of the metal reversal plates 15 and 25.

  Furthermore, instead of the pressure wheel 31 shown in FIG. 3, the pressure wheel 31 shown in FIG. 6 may be attached to the rear ends of both frame plate portions 4 of the body 2. Unlike the one in FIG. 3, the pressure reducing rod 33 of the pressure reducing wheel 31 shown in FIG. 6 is inclined with respect to the left-right direction.

  Further, the front frame portion 6 and the rear frame portion 7 included in the airframe 2 may have the same length (including substantially the same length) as the width dimension (machine width) of the airframe 2, for example, and the cross-sectional shape thereof It is arbitrary such as a quadrangle or a circle.
