Description

DETAILED DESCRIPTION OF THE INVENTION (Field of Industrial Application) The present invention relates to an agricultural land leveling machine that is pulled by a tractor or the like to level farmland.

(Prior art and problems) Conventionally, plowing has been carried out on farmland using a plow pulled by a tractor or the like. To properly perform soil preparation, it is necessary to make the coarse soil particles on the ground fine, to properly compact the lower layer, and to flatten the ground surface. Therefore, after plowing, it is necessary to perform land leveling work using land leveling equipment such as a power harrow.

Therefore, working efficiency is reduced, and since the tractor travels again on farmland that has already been plowed, the plowed soil is compacted by the wheels, resulting in poor workability and making it impossible to obtain the desired level of land. Also, a system has been proposed in which a plow is equipped with a rotary harrow to perform multiple tasks, but this has the problem that it cannot be realized because the speeds of each task are different.

(Object of the invention) The present invention was made in view of such busy circumstances, and
To provide an agricultural land leveling machine which can finish leveling work at the same time as plowing work, has good workability, and can properly compact the lower layer to obtain ground leveling with fine particles and a flat surface. purpose.

(Structure of the Invention) The agricultural land leveling machine according to the present invention is characterized in that a ground leveling section is provided at the rear of the vehicle body integrally with the plow body.

(Example) The present invention will be described in detail below based on an example shown in the drawings.

FIG. 1 shows an embodiment of the present invention, which is composed of a plow body 1 and a ground leveling section 2.

The main body 1 can be a conventional commercially available plow, and in this embodiment, the tip has a towing part 1 for a tractor or the like.
A frame 4 whose plane is approximately in the shape of a cutting edge is connected to the rear end of the connecting frame 3 forming a shape so that it can rotate in the horizontal direction about the center of the horizontal rod 5 at the tip. Rear part 6a of vertical rods 6 and 7.

7aK has a configuration in which the main bodies 8 and 9 are attached facing downward, and the soil from when the rear side car body 8 forms a plow groove is thrown into the plow groove formed by the preceding car body 9. It is.

The rear part 7aK of the vertical rod 7 of the frame 4 has a tip 10a of a support rod 10 extending obliquely outward and rearward secured to the mounting portion of the vehicle body 9 with the same mounting bolt 11. A ground leveling front 2 is rotatably fixed at the center of the end portion 10b.

In this embodiment, as shown in FIG. 2, a rotating shaft 14 is pivotally connected between the legs Lla and 13b of the gate-shaped frame. 1
5 is fixed, branch lines 16 are installed at parallel intervals between the peripheral edges of these disks, and furthermore, a pin 17 protruding from the center of the frame sphere is connected to the support rod l.
It is configured to be fitted into a cylinder 1B formed at the rear end portion 10b of the cylinder 1B, to be rotatably connected thereto, and to be fixed in a predetermined position by a tightening screw 19. Further, in this embodiment, the ground leveling front 2 only needs to be located at the rear of the vehicle body 9, and therefore the support rod 10 for connecting and pulling the ground leveling front 2 is bent into a substantially dogleg shape. Note that the ground leveling tool in the present invention is not limited to the configuration shown in this embodiment as long as it has a machine shape.

In order to use the agricultural land leveling machine having such a configuration, the traction part 2 formed at the tip of the plow body 1 is connected to a tractor etc. as in conventional plowing work, and the vertical angle of the vehicle body 8.9 and The horizontal angle is selected as appropriate to suit the farmland, and it is used in the same way as traditional plowing. This is what makes the lid run. The horizontal direction of the vehicle body 8°9 is determined by rotating the frame 6 around the horizontal rod 5 at the tip. In other words, when the frame 6 rotates, the support rod W fixed to the frame 6 also rotates at the same time, and the rotation axis 14 before leveling 2 is not perpendicular to the direction of movement, making it difficult to perform leveling work properly. Loosen the tightening screw 19 that fixes the support rod 10 and rotate the rotation shaft 14 around the bottle 17.
is rotated perpendicular to the traveling direction, and then the tightening screw 19 is tightened again. As the tractor travels, a grout groove is formed by the e bodies 8 and 9, and the soil dug up from the main body 8Vc is removed from the main body 91.
The soil leveling basket 2 passes over the mountain-shaped plow groove formed by C, and at this time, the soil leveling basket 2 flattens the ground surface, finely breaks coarse soil particles on the surface, and further removes the lower layer. After proper suppression, ridge formation and seeding.

It is possible to obtain a level surface suitable for carrying out various operations such as transplanting easily and neatly.

(Effects of the Invention) The agricultural land leveling machine of the present invention has a structure in which one or two soil leveling baskets are provided at the rear of the plow body, so that plowing work and land leveling work can be performed in one operation. It is efficient and has good soil leveling performance as there is no need for a tractor to drive through the ground that has been previously plowed to level the ground. Also, since it uses a leveling basket as a leveling tool, it can be used over a large area. This plow flattens the ground surface, crushes the ground into fine soil particles, and properly compacts the underlying layer, making it easy to level the ground for subsequent work in a short time.Moreover, the plow itself is similar to conventional plows. It is economical because the plow can be used as is, and has various effects such as excellent durability.
