The field digging machine is provided with a crushing structure for crushing the closed soil generated in the existing digging ditch due to the progressive formation of the crushing member by the crushing member.

As described above, in the invention according to claim 1, the machine frame is driven by the traveling machine body , the lower part of the plow member is penetrated into the field scene, and the field soil is dug up by the plow member. Field scattered materials such as straw debris that are discharged to the side and scattered in the field scene in front of the plow member in the traveling direction are discharged to the side by the pretreatment member, and the grooving work can be performed well. , the field soil provided collapsible crushable member freely swing vertically, closed soil occurs at the intersection between the existing drilling Tomizo by dug member Ki referred above, or, taken dug by the plow member side Occurs in the existing excavation ditch due to the progressive formation of the above excavation ditch as a closed soil in the existing excavation ditch caused by the fall of the excavation soil discharged toward the side into the existing excavation ditch. Since it is provided with a crushing structure that crushes the closed soil with a crushing member, the crushing member rolls and travels in the field scene, descends and swings into the existing excavation ditch, and rides on the field scene. The ascending and oscillating motion is repeated, and the crushing member crushes the closed soil as a barrier that blocks the flow path of the existing digging groove by the descending swaying motion of the crushing member into the existing digging groove. The flow path can be secured, the drainage drainage property is not hindered, and the drainage function of the excavation ditch can be reliably maintained.

Then, as shown in FIG. 7, when the excavation groove W is progressively formed, the crushing roll portion 26a of the crushing member 26 rolls around the field scene a and intersects the existing excavation groove WK to perform the existing excavation. When located in the groove WK, the crushing member 26 swings downward and swings around the connecting pin 25, and is dug by the closed soil DH or the plow member 11 generated at the intersection with the existing excavation groove WK by digging the plow member 11. Due to the blockage soil DH in the existing excavation ditch WK caused by the drop of the excavation soil D taken and discharged to the side into the existing excavation ditch WK, that is, the progressive formation of the excavation ditch W. As shown in FIGS. 7, 8 and 9, the closed soil DH generated in the existing excavation groove WK is crushed by the crushing member 26 due to the downward swing of the crushing member 26 centering on the connecting pin 25. As a result, when passing through the existing excavation groove WK, the crushing member 26 rises and swings around the connecting pin 25, and the crushing roll portion 26a of the crushing member 26 rides on the field scene a and rolls. The crushing member 26 crushes the closed soil DH by the downward swing of the crushing member 26, and the flow path can be secured by crushing the closed soil DH as a barrier to block the flow path of the existing excavation groove WK.

Since the example of this embodiment has the above configuration, as shown in FIGS. 1 and 2, the machine frame 3 is lowered by the connecting mechanism 2, and the lower part of the groove cutting body 8.8 and the lower part of the plow member 11 are field scenes. The machine frame 3 is driven by the traveling machine body 1 after penetrating into a, and the field scattered matter E such as straw debris and stocks scattered in the field scene a located in front of the groove cutting body 8 and 8 in the traveling direction is It is discharged to the side by the pretreatment member 20, and the grooving resistance of the grooving body 8.8 and the grooving resistance of the plow member 11 can be reduced accordingly, and the grooving body 8.8 rotates around. As it progresses, a double-row groove R is cut in the field scene a, and in this case, the grooving resistance is reduced by the blade portions 8a and 8a, and the soil between the two-row grooves is dug by the plow member 11 behind the groove. discharged taken in laterally stabilizing members 22 diastema member 11 by digging fringed the drilling Tomizo W field on edge surfaces W ₁ · _{W 1} and the inner groove side surfaces forming both upper corner edges of the left and right It _{is in sliding contact with W 2} and W _2, and the height of the plow member 11 can be stabilized by the stabilizing member 22, and the plow member 11 excessively scoops the field mud depending on the condition of the field soil, and the traction force increases. Can be suppressed, the depth of the excavation groove W can be kept substantially constant, and the grooving work of the excavation groove W can be smoothly performed.

In this case, FIG. 5, as shown in FIG. 6, the stability in the member 22, which can be brought into sliding contact with the field on the edge surfaces W ₁ · _{W 1} of the right and left to form the two upper corner edges of the right and left of the drilling Tomizo W upper contact plate face 22a · 22a, connecting plate surface 22c between the right and left groove side _W 2 · _{W 2} in slidable contact with side abutting plate surfaces 22b · 22b and left and right side abutment plate surface 22b · 22b are formed Since the front edges of the upper abutting plate surfaces 22a and 22a and the connecting plate surface 22c are formed on the curved rising surface, the height of the plow member 11 can be stabilized by the upper abutting plate surfaces 22a and 22a. In addition, the side contact plate surfaces 22b and 22b of the stabilizing member 22 can suppress the lateral runout of the plow member 11 and the groove cutting body 8 and 8, so that the grooving work can be performed well and the crushing member 26 can be performed. The crushing structure of the can be simplified.

At this time, as shown in FIGS. 5 and 6, the crushing member 26 capable of crushing the field soil is connected to the stabilizing member 22 by the connecting pin 25, and the crushing member 26 can swing up and down around the connecting pin 25. The crushing member 26 is formed in a cylindrical roll shape capable of rolling and traveling in the field scene a, and is a closed soil DH or a plow generated at an intersection with an existing excavation groove WK by digging the plow member 11. Progress of the above-mentioned excavation groove W as a closed soil DH in the existing excavation groove WK caused by the drop of the excavation soil D excavated by the member 11 and discharged to the side into the existing excavation groove WK. Since the closed soil DH generated in the existing excavation groove WK due to the formation is provided with a crushing structure due to the weight of the crushing member 26 and the weight 29, the crushing member 26 rolls in the field scene a. The downward swinging motion into the existing excavation groove WK and the climbing / rising rocking motion to the field scene a are repeated around the connecting pin 25, and the crushing member 26 is inserted into the existing excavation groove WK. The crushing member 26 can crush the closed soil DH as a barrier to block the flow path of the existing excavation groove WK by the downward swinging operation of the crushing member 26 to secure the flow path of the excavation groove W / WK, and has drainage and drainage properties. The drainage function of the excavation ditch W / WK can be reliably maintained.

In the above embodiment, the grooving bodies 8.8 are made up of two pairs of grooving bodies, but the grooving bodies 8.8 can be used as a blade-shaped grooving blade, or one of the grooving bodies. In some cases, the groove cutting body is forcibly rotated, and in the above embodiment, a pair of groove cutting bodies 8.8 and a plow member 11 are arranged as a pair. It may be a set or more, and the structure and the like of the stabilizer 22 are appropriately modified and designed.

Further, in the above-described embodiment, the closed soil DH is crushed by the weight of the crushing member 26 and the weight 29, but a crushing structure may be adopted by a spring mechanism.

As described above, the intended purpose can be sufficiently achieved.
