  In general, in finishing work, the finishing condition of the paddy is affected by soil and soil conditions such as clay, sand, voids, and weather conditions during finishing work, such as clear weather and rainy weather. For example, in the case of trimming work using a rotary trimming body having a plurality of pressing plate bodies, it is suitable for sanding soil and dry trimming work. In the case of trimming work by a rotating trimming body having a smooth conical surface or a cylindrical surface, which is made of resin and has a continuous surface, the surface is relatively clayey and wet. It turns out to be suitable for work.

  That is, in the relatively clayey soil and wet state, when the sizing work is performed with the rotary sizing body having the plurality of pressing plate bodies, in the finished state, the surface of the slag is wavy, In some cases, the surface soil is relatively easy to collapse due to the partial peeling of the surface soil, and the pressing state inside the clay may be lowered.

  However, in the case of the conventional structure, the plurality of pressing plate bodies are made of the same material, thickness, and shape, that is, a plurality of pressing plate bodies made of the same rigid plate material are used. The rigidity here is determined based on the material of the plate material, the thickness of the plate material, the cross-sectional shape of the plate material, etc., and means the force (load / deformation amount) required to cause unit deformation. Therefore, there is an inconvenience that there is a strong demand for a finishing work that achieves a good finish without being affected by soil conditions and weather conditions during the finishing work.

  SUMMARY OF THE INVENTION The present invention aims to solve such inconveniences. Among the present inventions, the invention according to claim 1 connects a machine frame to a traveling machine body by a connection mechanism, Is provided with a leveling mechanism having a rotary leveling body capable of rotating and leveling the surface by press-fitting rotation at a rear position in the advancing direction of the banking mechanism. There are provided a plurality of pressing plate bodies having flexible elasticity, and the plurality of pressing plate bodies are composed of several kinds of plate materials having different rigidity from each other. .

  According to a second aspect of the present invention, the rotary trimming body comprises a side trimming body capable of trimming one side surface of the scissors and a top surface trimming body capable of trimming the top surface of the scissors. And / or a plurality of pressing plate bodies disposed on the outer peripheral portion of each of the upper surface trimming bodies, wherein the plurality of pressing plate bodies are made of several types of plate materials having different stiffnesses. The invention according to claim 3 is characterized in that the plurality of pressing plate bodies made of several kinds of plate materials having mutually different stiffnesses are made of a plate material having a small rigidity along the rotation direction of the rotary adjusting body. In this invention, the plurality of pressing plate bodies are different in rigidity from each other in magnitude. It is characterized in that it is made of a kind of plate material, and the invention according to claim 5 A plurality of pressing plate bodies made of two types of plate materials having different properties are arranged alternately and repeatedly along the rotation direction of the rotary trimming body. The invention according to Item 6 is characterized in that the magnitude of the rigidity is determined depending on the material of the plate material, the thickness of the plate material, the cross-sectional shape of the plate material, and the like.

  As described above, in the invention according to claim 1, the present invention causes the traveling machine body to travel along the old paddle, while the embankment mechanism continuously raises the paddy field mud up to the old paddle. On the other hand, the adjusting mechanism is driven, the rotating adjusting body rotates and adjusts the surface, and a plurality of pressure-clamping plates having flexible elasticity are arranged on the outer peripheral portion of the rotating adjusting body. Therefore, the pressing plate body gradually pressurizes the embankment as the rotary trimming body rotates, and the pressing plate body has flexible elasticity. Can be gradually tightened, the embankment can be securely clamped, and a more robust ridge can be obtained. In this case, the plurality of pressing plate bodies have several kinds of rigidity different from each other. Because it is made of a plate material, the rigidity of the plate differs depending on the size, for example, the elastic modulus of the pressed plate body, how to bend, and the degree of pressure contact of the heel Clamping plates with different strengths can be obtained, and by performing trimming work with pressure plates with different stiffness, it is greatly affected by the soil conditions of the field, dredging, and weather conditions during trimming. Therefore, it is possible to perform a trimming operation that achieves a good finished state.

  According to a second aspect of the present invention, the rotary trimming body comprises a side trimming body capable of trimming one side surface of the collar and an upper surface trimming body capable of trimming the upper surface of the collar. A plurality of pressure plate bodies having flexibility and elasticity are arranged on the outer periphery of each of the trimming body and / or the upper surface trimming body, and the plurality of pressure plate bodies have several kinds of different stiffnesses. Therefore, the upper surface and / or one side surface of the heel can be rotationally adjusted by the pressing plate body of the side surface adjusting body and / or the upper surface adjusting body of the rotary adjusting body and the pressing operation can be performed. Since the plate bodies have different stiffnesses, it is possible to obtain pressure plate members that have different elastic modulus, bending method, and strength of the pressure contact of the flanges. By performing the trimming work with the clamp plate, it is not so much affected by the soil condition of the field and straw, and the weather conditions during the trimming work. In addition, in the invention according to claim 3, a plurality of pressing plate bodies made of several kinds of plate materials having different rigidity are From a small rigid plate material to a progressively larger rigid plate material in order along the rotation direction of the rotary trimming body, it is sequentially arranged from a small clamping force to a large clamping force as the rotary trimming body rotates. In the invention according to claim 4, the heel can be squeezed gradually and repeatedly, and the sledge can be squeezed by repeating this operation, and the sizing operation can be performed to achieve a good finish. The above-mentioned plurality of pressing plate bodies are composed of two types of plate materials having different rigidity from each other. Therefore, the effect of having different rigidity from each other can be obtained while minimizing the types of pressing plate bodies. In the invention according to claim 5, Since the plurality of pressing plate bodies made of two kinds of plate materials having different stiffnesses from each other are alternately arranged along the rotation direction of the rotary trimming body, the collar surface is alternately weak and strong. The weak and strong tightening pressure is repeated, and the rivet can be tightened as much as that. In the invention of claim 6, the magnitude of the rigidity depends on the material of the plate, the thickness of the plate, Since it is determined depending on the cross-sectional shape or the like, the rigidity of the pressing plate body can be easily determined.
