Description

[Detailed description of the device]

[0001]

[Industrial applications]

 The present invention relates to a field leveling work machine capable of leveling the surface of a paddy field by transporting mud soil at a high level on the surface of a paddy field after harvesting to a low level.

[0002]

[Prior art]

 In the past, if the paddy field was not leveled and the irrigation was poor, after harvesting, dig the high place with a scoop and transport it to a low place with a unicycle etc. I was doing conversion work.

[0003]

[Problems to be solved by the device]

 However, since such work is performed by human power, it is a great labor, and it is a dangerous work, and the work efficiency is not improved.

[0004]

[Means for Solving the Problems]

 The present invention has been devised to solve such problems and to perform leveling work with good workability. Therefore, the front part of the machine body that is connected to the lifting body that can be lifted and lowered at the rear of the towing vehicle. A plurality of disc cutters arranged side by side at a predetermined interval in the horizontal direction are rotatably mounted on the shaft, and the excavating scaffolding plate is extended to the rear from the lower part between the adjacent disk cutters. A bucket having a sled at the bottom is connected to the rear portion of the excavating and scooping plate so as to be freely rotatable through a hinge.

[0005]

[Action]

 Therefore, when the tow vehicle pulls the aircraft at a high level in the paddy field after harvesting, each disc cutter automatically rotates and cuts the upper layer surface of the paddy field, excavating mud between adjacent disc cutters. While being scooped up on the board, it is washed away as it is, and it will be received in the bucket that is sliding following the back, and then it will be moved to the lower part of the paddy field and the lifting body will be raised. However, when the aircraft is lifted up, the bucket turns around the hinge and tilts backward, and the mud in the bucket can be discharged onto the low paddy field.

[0006]

【Example】

 B indicates a towing vehicle that is an agricultural tractor. A rear part of the rear case 7 at the rear of the tractor is connected with a rotary working machine C having a rotary 8 at the bottom through a three-point link mechanism 9 and a lift on the rear case 7. The arms 10 allow the rotary working machine C to move up and down, the front ends of the rotary working machines C pivotally support the front ends of the arms 11, and the rear ends of both arms 11 support a tail wheel 12 and a depth beam. A horizontally elongated lifting body 1 is connected, and a telescopic adjustment rod 14 with a handle 14a for lifting the lifting body 1 is interposed between the upper mast 13 and the middle portion of the arms 11 to provide a conventional structure. Although the structure is similar, it is also possible to use a management machine or a carrier as the towing vehicle.

Reference numeral A denotes an entire leveling work machine, in which both side portions of a rotary shaft 15 which axially supports four disc cutters 2 arranged in parallel at a predetermined interval in the lateral direction are supported by both bearings 16 and 16. The supporting arms 17, 17 extending from the bearings 16, 16 to the upper front side can be fitted to the lifting body 1 and can be detachably connected by a connecting pin 18 in a side view. -Shaped hitches 19 and 19 are fixedly provided, and the excavating and scooping plate 3 inclined forward and backward and rearward is extended rearward from the lower portion between the adjacent disc cutters 2 and 2. The tips of the four support arms 20 extending upward from the upper part of the excavation and scooping plate 3 on the rear side are connected to the intermediate parts of the support arms 17 and 17, respectively. The side plate 5a is inclined and at least three are provided on the lower surface. The lower part of the front of the bucket 5 having the sled 4 and having the upper edge of the front part at the same height as the height of the upper surface of the rear end of the excavating and scooping plate 3 is placed behind the excavating and scooping plate 3. It is configured to be freely rotatably connected via a hinge 6 to the lower end portion.

Therefore, as shown in FIG. 1, the rotary working machine C is lifted up so that the rotary 8 does not come into contact with the paddy field and the expansion and contraction of each disk cutter 2 slightly bites into the paddy field after harvesting. When the working machine A is lowered by the rod 14 and towed by the towing vehicle B, each disc cutter 2 automatically rotates to chop the upper layer surface (shown by a) of the paddy field. The mud between the two and two is scooped up on the scooping scooping plate 3 while being swept away as shown by the arrow B, and is received in the bucket 5 which is slid following the rear. After that, by moving it to a low place on the surface of the paddy field and lifting the lifting body 1 while raising the rotary working machine C, as shown in FIG. As the bucket 5 rotates about the hinge 6 and tilts backward, the mud in the bucket 5 can be discharged onto the low paddy field as indicated by the arrow C.

[0009]

[Effect of device]

 In this manner, the present invention can be towed by the towing vehicle B, scooping the upper layer surface of the paddy field by each disk cutter 2 and scooping up by the excavation scooping plate 3 to be received by the bucket 5, and also on the paddy field surface. By sliding the mud and transporting the mud to raise the lifting / lowering body 1, the bucket 5 can be tilted to discharge the mud, and the leveling work of the paddy field where the mud at the high surface of the paddy is moved to the low However, unlike the conventional method, it can be effectively and efficiently performed without requiring human power, and can be effectively used only by connecting the working machine to the towing vehicle B having the vertically movable elevator 1. It has a feature that it can be suitably implemented with a simple structure.
