Patent No. 4154545 Patent No. 3622164 Patent No. 3493612

Generally, in ridge preparation work such as ridge preparation and ridge restoration, for example, the soil properties of the field and ridge such as clay, sand, gap ratio, water content ratio, particle size, etc., and for example, fine weather, rainy weather, etc. It is known that the finish condition of the ridges is affected by the weather conditions during the ridge preparation work.

For example, in the case of ridge preparation work using a rotary ridge preparation body having a plurality of compression plates, the soil is relatively sandy and the weather conditions are suitable for ridge preparation work in a dry state. On the other hand, in the case of ridge preparation work by a rotary ridge having a fixed surface plate body formed of a metal material or a resin material on the outer peripheral portion of the rotary ridge and having a continuous smooth surface on the entire surface. It has been found that the soil is relatively clayey and suitable for ridge preparation work in a wet state.

That is, when the ridges are trimmed by the rotary ridges having a plurality of compression plates in the relatively clay soil and in a wet state, the surface of the ridges may undulate in the finished state. There is a disadvantage that the surface soil is relatively liable to collapse due to partial peeling of the epidermis soil of the ridges, and the compression state inside the ridges may be lowered.

The present invention aims to solve such inconveniences, and in the present invention, the invention according to claim 1 connects a machine frame to a traveling machine body by a connecting mechanism, and the old ridge is connected to the machine frame. An embankment mechanism for raising soil is provided in the ridge, and a ridge mechanism having a rotary ridge capable of rotating the ridge surface by pressure welding rotation is provided at a position rearward in the traveling direction of the fill mechanism. The portion is formed on the ridge surface in a compression region capable of rotationally adjusting the ridge, and the compression region is divided into a fixed compression region and a movable compression region in the rotational circumferential direction of the rotary ridge, and the movable pressure is formed. The tightening region is a single or a plurality of compartments in the compression region, the fixed compression region is composed of a fixed face plate body, the movable compression region is composed of a movable face plate body, and is divided into the movable compression region. A through hole is formed in the outer peripheral portion of the rotary ridge, and the fixed compression region is a remaining compartment of the movable compression region larger than the division of the movable compression region. It is on the ridge.

Further, in the invention according to claim 2, the movable face plate body is made of a compression plate body having flexible elasticity, and the front end portion of the compression plate body in the rotation direction is a mounting portion of an outer peripheral portion of the rotation ridge body. The rear end in the rotation direction is formed at the free end that can be separated from the outer peripheral portion of the rotary ridge, and the compression plate of the outer peripheral portion of the rotary ridge is formed at the fixed end. It is characterized in that a compression surface portion is provided at a position facing the inner surface of the free end portion of the body.

As described above, in the invention according to claim 1, the present invention causes the traveling machine to travel along the old ridge, while the embankment mechanism continuously raises the field mud on the ridge on the old ridge, and on the other hand. The ridge adjustment mechanism is driven to rotate the rotary ridge, the outer peripheral portion of the rotary ridge is formed in a compression region capable of rotating the ridge surface, and the compression region is the rotary ridge of the rotary ridge. A compartment is formed in a fixed compression region and a movable compression region in the circumferential direction of rotation, the movable compression region is defined as one or more compartments in the compression region, and the fixed compression region is larger than the compartment of the movable compression region. Since it is the remaining section of the compression region, the ridge surface is rotationally adjusted by the fixed compression region and the movable compression region as the compression region of the outer peripheral portion of the rotary ridge, and is fixed. The ridge surface can be squeezed by the ridge surface, which has two types of squeezing action, which are different from the fixed squeezing action by the squeezing area and the movable squeezing action by the movable squeezing area, as well as during soil properties and ridge preparation work. Flexibility to weather conditions and the like can be obtained, and the ridge adjustment work can be performed satisfactorily, and the fixed compression region is composed of a fixed face plate body, and the movable compression region is made of a movable face plate body. Since it is configured, the ridge adjustment work is performed by pressure welding rotation contact by the continuous smooth fixed surface of the fixed surface plate in the fixed compression region, and pressure welding rotation contact by the movable surface of the movable surface plate in the movable compression region. The ridges are adjusted by the method, and the ridges can be compressed by two types of compression, fixed and movable by the fixed surface plate in the fixed compression region and the movable surface plate in the movable compression region. The ridge surface can be squeezed by the squeezing action, and the flexibility to the soil properties and the weather conditions at the time of ridge preparation work can be obtained, so that the ridge preparation work can be performed well and it is movable. Since a through hole is formed in the outer peripheral portion of the rotary ridges partitioned in the compression region, the compression plate gradually bends inward from a flat shape due to the presence of the through hole and gradually bends the embankment. It is possible to tighten the embankment to the inside, and the embankment can be gripped by the bending motion of the curved shape inward, so that the embankment can be reliably pressed, and more robust ridges can be obtained. It is possible to suppress the phenomenon of soil adhering to the compression plate body, and it is possible to perform good ridge preparation work.

Further, in the invention according to claim 2, the movable face plate body is made of a compression plate body having flexible elasticity, and the front end portion of the compression plate body in the rotation direction is an outer peripheral portion of the rotation ridge body. The rear end in the rotational direction is formed at the free end that can be separated from the outer peripheral portion of the rotary ridge, and is formed at the fixed end that is fixed to the mounting portion. Since the compression surface portion is provided at the position facing the inner surface of the free end portion of the free end portion, the compression plate body moves between the pressure contact position and the restoration position of the ridge surface due to its own flexible elasticity as the rotary ridge body rotates. The flap operation gradually tightens the filling, and the filling is strongly pressed due to the presence of the compression surface at the position facing the inner surface of the free end of the compression plate on the outer periphery of the rotary ridge, and the compression plate is acceptable. Since it has flexural elasticity, the compression plate body can flex from a flat state and flap to gradually tighten the filling, and the filling can be reliably tightened, resulting in more robust ridges. Obtainable.
